Overview
We
are a biopharmaceutical company focused on improving the intracellular delivery of critical therapeutics through our paradigm-changing
lipid nanocrystal (LNC) delivery platform. We are also focused on creating value through identifying a partner to continue
the development of LYPDISO™ (formerly MAT9001), a next generation, highly purified, prescription-only omega-3 free fatty
acid formulation specifically designed for the treatment of cardiovascular and metabolic conditions.
Matinas
BioPharma is dedicated to maximizing the value associated with our unique LNC platform delivery technology. This proprietary platform
technology, licensed from Rutgers University on an exclusive worldwide basis, nano-encapsulates target molecules in a way that
facilitates safe, efficient, and targeted intracellular delivery. Comprised of phospholipids, like phosphatidylserine, and calcium,
our LNCs can be differentiated from any other delivery technology today both in terms of how LNCs provide flexibility with route
of administration as well as how LNCs gain access to cells and how they can also provide flexibility with route of administration.
LNCs have been delivered orally, intramuscularly, intravenously and through inhalation. Because of their unique composition, LNCs
can be delivered into a cell through any or all of phagocytosis, membrane fusion, or clathrin-mediated endocytosis.
In
addition to efficient intracellular delivery to treat a variety of cell-based pathogens, diseases and conditions, our technology
allows for the targeted and safe delivery of pharmaceutical agents directly to sites of infection or inflammation. This highly
stable, efficient and broadly applicable drug delivery platform has the potential to deliver a broad range of therapeutic agents,
including small molecules, vaccines, peptides and proteins, as well as nucleic acid polymers (e.g., antisense, oligonucleotides,
siRNA, mRNA) for use in treating a broad range of inflammatory, infectious and other intracellular diseases (e.g., intracellular
pathogen-related, genetic disorders, and cancer).

Our
lead drug candidate based on the LNC platform delivery technology is MAT2203, an oral formulation of amphotericin B, a well-known
and highly effective, antifungal drug (though frequently associated with significant renal toxicity and currently only
available in an intravenous formulation) currently used and approved to treat a variety of invasive, and potentially deadly, fungal
infections. MAT2203 has been developed to date with the assistance and financial support of the National Institutes of Allergy
and Infectious Disease (NIAID) of the National Institutes of Health (NIH). MAT2203 has been designated as a Qualified Infectious
Disease Product (QIDP) with Fast Track Status for the treatment of invasive candidiasis, the treatment of aspergillosis, the prevention
of invasive fungal infections in patients who are on immunosuppressive therapy, and, most recently, the treatment of cryptococcosis.
While we continue to believe that MAT2203 could become an important solution to the significant unmet medical need to prevent
invasive fungal infections in immunosuppressed patients, we also believe there are opportunities for a more rapid approval of
MAT2203 for the treatment of certain invasive fungal infections in areas of high unmet medical need.
In
partnership with the NIH, we have conducted numerous preclinical studies of MAT2203 in cryptococcal meningitis and demonstrated
that MAT2203 was able to (a) cross the blood-brain barrier, (b) effectively treat this infection and (c) eliminate the toxicity
normally associated with delivery of amphotericin B intravenously. The NIH has funded a grant submission from the University of
Minnesota for a clinical study of MAT2203 in patients with cryptococcal meningitis in Uganda, where this disease is highly prevalent
among the human immunodeficiency virus (HIV)-positive community. This study, which has been called the Encochleated Oral Amphotericin
for Cryptococcal Meningitis Trial (EnACT), initiated in 2019 and currently enrolling patients in Cohort 2 of the trial,
is exploring the use of MAT2203 for both induction and maintenance therapy, and we believe that, if positive, it could form the
foundation for registrational approval in this indication. Moreover, since this study potentially validates the use of MAT2203
in what is arguably one of the most difficult-to-treat fungal infections, we believe MAT2203 is well-positioned to become a best-in-class
antifungal drug for the treatment of invasive fungal infections. Furthermore, a demonstration that MAT2203 can effectively cross
the blood-brain barrier in humans could potentially position our LNC platform delivery technology for use with molecules designed
to treat other inflammatory diseases of the central nervous system through an oral route of administration. Developing MAT2203
utilizing primarily non-dilutive, government-sponsored, financing allows us to focus our internal cash resources on LYPDISO while
advancing MAT2203, MAT2501 and our innovative LNC platform delivery technology.
We
are also progressing the development of MAT2501, our oral amikacin development program, which is funded in large part by the Cystic
Fibrosis Foundation (CFF) which we are developing for the treatment of non-tuberculous mycobacterial (NTM) infection, a highly
prevalent lung infection in patients with underlying cystic fibrosis. We received funding of $3.75 million from the CFF in November
2020 which was based upon the positive preclinical proof-of-concept data generated by Colorado State University testing MAT2501
efficacy against both amikacin-sensitive and resistant strains of infecting organisms in a CF mouse model for NTM infections.
We
have been engaged in discussions with various large, well-established and well-financed biotech and global pharmaceutical companies
on potential applications of the LNC platform delivery technology.
●
In
July 2018, we announced a research collaboration with the National Institute of Neurological Disorders and Stroke (NINDS)
of the NIH, focused on the development of a novel therapy for the treatment of HIV combining targeted antisense oligonucleotides
(ASO) and Matinas’ LNC platform delivery technology.
●
In
January 2019, we announced a research evaluation with a top global pharmaceutical company in which our LNC platform delivery
technology would be explored in delivering certain nucleic acid polymers.
●
In
May 2019, we announced a research collaboration with ViiV Healthcare to develop and evaluate formulations of antiviral drug
candidates.
●
In
December 2019, we announced a feasibility collaboration with Genentech relating to the development of oral formulations of
a number of Genentech proprietary compounds applying the LNC platform delivery technology.
●
In
December 2020, we announced a collaboration with the National Institute of Allergy and Infectious Diseases to evaluate oral
formulations of Gilead’s antiviral remdesivir utilizing our LNC platform delivery technology.
We
continue to evaluate additional potential strategic collaborations with other interested biotech and pharmaceutical partners.
These early stage, proof-of-concept evaluations could provide an efficient, less expensive pathway to create numerous strategic
verticals in areas of innovative medicine while capitalizing on the development expertise and financial resources of well-established
pharmaceutical and biotech companies. Data from these evaluations could position us as a licensor of our LNC platform delivery
technology to numerous strategic partners better positioned to absorb the risks and costs of drug development while allowing our
company to become a royalty aggregator with the potential to generate upfront license, milestone and royalty payments as we maximize
the value of the overall LNC platform delivery technology.
3
We
are also focused on securing value for LYPDISO through a collaboration or partnership in the United States or globally. LYPDISO
is a soft gelatin capsule containing a complex mixture of multiple long-chain omega-3 fatty acids, primarily eicosapentaenoic
acid (EPA) and docosapentaenoic acid (DPA). There are a number of existing FDA-approved prescription omega-3 products, including
Lovaza®, Vascepa® and Epanova®, and this class of drugs has extensive evidence of safety and well-documented clinical
efficacy in lowering triglycerides (TGs) in patients with hypertriglyceridemia (HTG). We believe that given LYPDISO’s enhanced
bioavailability (as a free fatty acid rather than an ethyl ester) and its unique composition (high EPA plus DPA, with very little
DHA), it is differentiated from other existing products in the omega-3 class.
Triglycerides
(TGs) and cholesterol are integral components of lipoproteins, the primary transport vehicle for lipids in the body. High levels
of triglyceride-rich lipoproteins are associated with a substantially increased risk of atherosclerotic cardiovascular disease,
and, in the case of very high triglycerides, acute pancreatitis. Triglyceride elevations can be due to both genetic and environmental
factors and are frequently associated with comorbid conditions such as diabetes, chronic renal failure, and nephrotic syndrome.
Unlike the currently approved pharmaceutical omega-3 products, all of which have been repurposed following clinical failures in
their originally intended indications, LYPDISO has been specifically designed and developed to treat HTG, dyslipidemia and other
cardiovascular and metabolic conditions.
We
had previously been focused on the initial development of LYPDISO for an initial indication for the treatment of severe hypertriglyceridemia
(SHTG), which are those patients with triglyceride levels ≥ 500mg/dL, since TG-lowering is a well-accepted surrogate outcome
marker of clinical efficacy in these patients. Additionally, the prescription omega-3 product Vascepa has been approved for cardiovascular
risk reduction in patients at high cardiovascular risk with TGs ≥ 150 md/dL. The development plan for LYPDISO is via a 505(b)(2)
regulatory pathway, which tends to be shorter and less expensive than under Section 505(b)(1) (for new chemical entities that
have never been approved in the United States). The 505(b)(2) pathway allows us to rely, at least in part, on U.S. Food and Drug
Administration (FDA) findings of safety and/or effectiveness for a previously approved drug. Based on prior written feedback received
from the FDA in 2014, and additional verbal and written feedback from FDA in August of 2020, we believe that a 505(b)(2) pathway
is possible and appropriate for LYPDISO.
In
parallel with the preclinical and clinical studies necessary for FDA approval of LYPDISO, we also recently completed the ENHANCE-IT
study, a head-to-head crossover study of LYPDISO vs. Vascepa, which was intended to differentiate LYPDISO from the current leading
prescription omega-3 therapy. While the primary endpoint of percent change in TGs from baseline to end-of-treatment did not meet
statistical significance in the prespecified pharmacodynamic (PD) population, analysis of the per protocol (PP) population demonstrated
statistically significant improvement and superiority of LYPDISO over Vascepa in TGs, total cholesterol and very-low-density lipoprotein
(VLDL) cholesterol. A key secondary endpoint in ENHANCE-IT was the measurement of eicosapentaenoic acid, or EPA levels, in the
blood, as that has become a key surrogate marker in determining cardiovascular risk reduction. In ENHANCE-IT, plasma EPA concentrations
were significantly higher with LYPDISO vs. Vascepa (46% relative percent increase change from baseline EPA level vs. Vascepa)
and we believe indicate the potential for superior cardioprotection with LYPDISO vs. Vascepa. Overall, the data from ENHANCE-IT
support the pursuit of cardiovascular outcomes indication for LYPDISO. Given the significant time and expense of conducting a
cardiovascular outcomes trial, we have determined that a partner will be required to further develop LYPDISO. We have initiated
a process to identify and secure a partner over the next few quarters.
Strategy
We
are focused on improving the intracellular delivery of critical therapeutics through our paradigm-changing lipid
nanocrystal (LNC) drug delivery platform and its application to overcome current challenges in safely and effectively delivering
small molecules, nucleic acids, gene therapies, proteins/peptides, and vaccines. We are also focused on creating value through
finding a partner to continue the development of LYPDISO, our proprietary, next-generation prescription omega-3 drug, which we
believe is differentiated from all other prescription omega-3 products and positioned to potentially demonstrate superior cardioprotective
effects.
4
Key
elements of our strategy include:
●
Advancing
our clinical stage assets based on our LNC platform delivery technology and continuing to expand utilization of this promising
technology into areas of innovative medicine.
●
Delivering
efficacy data for MAT2203 in the EnACT study for the treatment of cryptococcal meningitis, which would highlight the safety
and efficacy of this promising drug candidate, while demonstrating the ability of our LNC platform technology to deliver potent
medicines across the blood-brain barrier with oral administration.
●
Progressing
the development of MAT2501 through extensive preclinical toxicology and efficacy studies in NTM infections and completing
a single ascending dose pharmacokinetic study in healthy volunteers later in 2021, all with the financial support of the Cystic
Fibrosis Foundation.
Our
Lipid Nanocrystal (LNC) Platform Delivery Technology
Efficient
and safe delivery of medicines remains one of the biggest challenges in the pharmaceutical and biotech industry today. The advancement
of science and the emerging importance of cell-mediated immunity and current challenges associated with effective intracellular
drug delivery has created a significant area of need. Current technology options, including liposomes, lipid nanoparticles (LNPs)
and viral vectors, have been widely adopted but each have significant limitations including inefficient delivery, undesirable
and dangerous toxicity and immunogenicity, and unstable formulations forcing challenging storage conditions (Figure 1). The method
in which these technologies gain access to a cell varies and often is responsible for significant adverse effects for patients.
Despite these known challenges, adoption has been widespread due to the lack of viable alternatives. Today, LNPs and viral vectors
are being used to deliver both small molecules and gene therapy.
Figure
1: Current Delivery Technologies
Our
Solution: LNCs
Our
proprietary lipid nanocrystals (LNCs) are primarily composed of two naturally occurring materials: a phospholipid, like phosphatidylserine
(PS), and calcium. They are stable and have a unique multilayered structure consisting of a large, continuous, solid, lipid bilayer
sheet rolled up in a spiral or as stacked sheets, with no internal aqueous space. This unique structure provides protection from
degradation for molecules trapped in or between lipid bilayers. Components within the interior of the LNCs remain intact, even
though the outer layers of the LNCs may be exposed to harsh environmental conditions or enzymes (Figure 2).

Figure
2 LNC Formulation
Our
LNCs protect active pharmaceutical ingredients in lipid bilayers and can intercalate into the phospholipid interior or otherwise
remain trapped within the bilayers (Figure 3). The presence of minimal amounts of calcium keeps the LNCs intact.
Figure
3 LNCs Protect API in Bilayers
LNCs
can be delivered in a variety of ways, including orally, intramuscularly, intravenously and through inhalation. This flexibility
represents a significant advantage over other delivery modalities and presents significant opportunities to efficiently encapsulate
many different molecules, both water soluble and water insoluble, including small molecules, nucleic acids such as antisense oligonucleotides
(ASOs), messenger RNA (mRNA) and small interfering RNA (siRNA), and nucleotides as large as eleven kilobases including DNA plasmids
and potentially CRISPR/Cas9, a gene editing technology.
6
Intracellular
delivery of molecules is usually accomplished by either phagocytosis, clathrin-mediated endocytosis (CME) or through membrane
fusion. LNPs are limited in that they can typically only access a cell through the CME process, followed by disruption of the
endosomal membrane within the cell to gain access to the cytoplasm. LNPs typically are very inefficient, and patients also experience
injection site adverse events and other toxicities associated with CME delivery, thereby limiting chronic use. LNPs also cannot
be delivered orally. Viral vectors, including adeno-associated virus, attempts to utilize nature’s intracellular delivery
mechanisms to facilitate fusion with the cell membrane and delivery of molecules into a cell. Unfortunately, viral vectors have
historically been associated with severe negative immune responses and, like LNPs, cannot be delivered orally. We believe LNCs
can effectively delivery molecules through all three mechanisms, in addition to having great flexibility with the desired route
of administration.
We
believe that LNC’s unique ability to enter a cell through phagocytosis, membrane fusion or CME, or a combination thereof,
relates directly to the presence of a phospholipid, like phosphatidylserine. Phosphatidylserine (PS) is present in virtually all
cells and is an integral part of the cell membrane. PS is normally localized to the inner part of the membrane bilayer by active
cellular processes. However, with cell “activation”, which occurs when there is infection, inflammation, injury, stimulation,
cell death or some other issue impacting a particular cell, PS moves from the inner layer to the outer layer and facilitates fusion
with our LNCs (Figure 4). Certain cells also contain PS receptors, which actively take up LNCs due to the presence of PS (Figure
5).
Figure
4: Asymmetry of the Phospholipid Membrane
7
Figure
5: Role of PS and PS Receptors in the Uptake of LNCs into Cells
Through
phagocytosis, macrophage and other cells containing PS receptors readily engulf LNCs and their drug cargo into vesicles, or endosomes,
facilitating intracellular delivery. LNCs can also fuse with cell membranes and deliver drug cargo directly to the cytoplasm.
LNCs have been designed to mimic enveloped viruses and can efficiently deliver drugs and/or molecules to cells without adverse
immune responses.
For
some molecules, the goal is simply to achieve safe and effective intracellular delivery. This is especially relevant when delivering
sensitive genetic material and other molecules desiring cellular impact (i.e., antivirals). For other molecules, or drugs, utilizing
activated cells as a mechanism to deliver drug to infected tissues or other areas of the body becomes critical.
LNCs
in pre-clinical studies have been shown to improve existing drugs by providing 1) cell-targeted delivery; 2) reduced blood
levels thereby reducing toxicity; and 3) oral delivery of drugs now only available intravenously. For example, LNCs delivered
orally work by encapsulating molecules of drugs in a solid, anhydrous, crystalline structure, protecting them as they pass through
the GI tract where they cross the mucous membrane. Once the LNCs have crossed the mucosal barrier of the GI tract into the lymphatic
system, they are picked up by activated cells including cells of the mononuclear phagocytic system, such as macrophages and dendritic
cells. Activated macrophages, with drug-loaded LNCs inside, follow natural signal molecule paths and migrate to the site of infection
or to the target organ and deliver their payload.
Therapeutic
applications of our proprietary delivery technology have been initially focused on the delivery of several potent and highly efficacious
anti-fungal and anti-bacterial agents, which are currently still associated with serious side effects, including irreversible
toxic effects on kidney and hearing function. We believe our technology has the potential for targeted delivery of these agents,
which positions us to be at the forefront of dealing with these very serious problems. We have now also expanded our research
and development efforts for our LNC platform delivery technology to focus on the delivery of a wide range of therapeutic treatments,
in particular those in the oligonucleotide class of agents (antisense oligonucleotides, mRNA, and CRISPR-Cas9).We continue to
push forward our business development efforts to further expand our collaborations across pharma and biotech companies who have
innovative therapies with delivery challenges, which may be addressed with our LNC platform delivery technology.
Multi-organ
Protection: A key innovation of our LNC platform delivery technology is our ability to package medication inside lipid-crystal
particles without leaking. Because of their crystalline nature, these particles are truly solid and hold on tightly to their medication
payload. This is where the LNC platform delivery technology differs markedly from other lipid-based delivery technology, such
as liposomal delivery. Liposomes are liquid delivery systems which typically leak some of their drug content into the circulatory
system, thus still exposing vulnerable organs and tissues to potential toxic effects. Keeping potentially organ-toxic medications
inside the lipid-crystal particles significantly differentiates our LNC platform delivery technology from other drug-delivery
approaches.
8
Targeted
Delivery: The size of our individual LNCs is typically in the range of 50-500 nm. This is very small and by comparison
close to the size of a large virus or a small bacterium. Our body produces many activated cell-types that are predisposed to interact
with our LNCs. These activated cell types, including bone marrow-derived hematopoietic cells such as macrophages, infected cells,
injured cells, tumor cells and epithelial cells are all prone to engulf or fuse with our phosphatidylserine-based LNCs. Because
of the size of our LNCs and their PS surface structure (the cell membranes of bacteria are also made up from PS), activated cells
tend to take up these LNCs very efficiently and without any adverse immune response.
Oral
Formulation: Many drugs that are currently on the market are only effective in treating diseases when administered intravenously.
For example, many anti-infective drugs must be administered intravenously in order to be effective. IV administration presents
several challenges to care, such as risk of infection, patient discomfort from injections, and higher cost of care than anti-infective
drugs that can be taken orally (IV delivery must be performed by a doctor or nurse, often within a very expensive hospital setting).
Although several technologies have been used to attempt to convert IV drugs to orally delivered medications, success has been
limited due to the difficulty in achieving adequate bioavailability (i.e., the amount of drug that is absorbed into the body)
with an oral formulation. We believe that the unique LNC structure in our platform technology protects the drug from degradation
when it passes through the GI tract and that its lipid surface features facilitate the particle being absorbed into the blood
stream. The potential application of our LNC platform delivery technology for the delivery of injectable medications offers significant
clinical and commercial value with successfully demonstrated safety and efficacy in human clinical trials.
Our
LNC platform technology changes the delivery of medicines in a unique manner and alters the bio-distribution of these medications
by targeting tissues and organs that are affected by infection and inflammation. In addition to IV-only anti-infectives such as
amphotericin B and amikacin, we have orally delivered in animal studies the influenza vaccine, siRNA, NSAIDs, other anti-infectives
such as atovaquone, and many other compounds across multiple therapeutic areas, demonstrating the potential broad application
of our technology. We have observed rapid local accumulation in infected tissues, which appear to be the result of transport of
our drug-loaded LNCs by and to activated cells.
Our
LNC Clinical Stage Assets
We
have leveraged our platform LNC delivery technology to develop two clinical-stage products that we believe have the potential
to become best-in-class drugs in their respective therapeutic classes. Our lead LNC platform delivery technology product candidate,
MAT2203, is an orally-administered LNC formulation of a broad spectrum anti-fungal drug called amphotericin B. We believe there
are opportunities for a potentially rapid approval of MAT2203 for the treatment of certain invasive fungal infections in areas
of high unmet medical need. In partnership with the National Institutes of Health (NIH), we have conducted numerous preclinical
studies of MAT2203 for the treatment of cryptococcal meningitis (CM), a deadly fungal infection that affects the brain, typically
in immunocompromised individuals. In such studies, we observed the potential for MAT2203, utilizing our LNC platform delivery
technology, to (a) cross the blood-brain barrier, (b) treat this infection and (c) eliminate the toxicity normally associated
with intravenous delivery of amphotericin B.
Based
upon the preclinical data generated by the NIH, the NIH has financially supported a grant application from the University of Minnesota
to conduct the EnACT study in Uganda. This study was initiated in October 2019 and is exploring the use of MAT2203 for both induction
and maintenance therapy in the treatment of CM, which is one of the most frequent and opportunistic infections in HIV patients.
Given the high morbidity and mortality associated with CM in HIV patients, the clinical unmet need is globally very high with
the global burden estimated at 1 million cases annually. We plan to leverage a 505(b)(2) regulatory pathway for MAT2203, in part
relying upon FDA’s findings of the efficacy of IV amphotericin B. This strategy was discussed with the FDA in June 2019,
where we outlined our development plans for MAT2203 in CM and received FDA approval to proceed with the EnACT study which is currently
enrolling subjects in Cohort 2 of the trial. We have received four qualified infectious disease (QIDP) designations as well as
an orphan designation for the treatment of cryptococcosis, which, if approved, would result in twelve years of regulatory exclusivity
for MAT2203. We plan to seek accelerated approval for this indication following the availability of the results of the ongoing
EnACT Study. We believe that this study may have the potential to become a potential pivotal study to support approval of MAT2203
for the treatment of CM during both induction and maintenance phases of treatment.
9
Our
second clinical stage LNC-based product candidate is MAT2501, an orally administered formulation of the broad-spectrum aminoglycoside
antibiotic amikacin, which may be used to treat different types of multidrug-resistant bacteria, including non-tuberculous mycobacterium
infections (NTM), as well as various multidrug-resistant gram negative and intracellular bacterial infections. In May 2017, we
completed and announced topline results from a Phase 1 single escalating dose clinical trial of MAT2501 in healthy volunteers
in which no serious adverse events were reported and where oral administration of MAT2501 at all tested doses yielded blood levels
that were well below the safety levels recommended for injected amikacin, supporting further development of MAT2501 for the treatment
of NTM infections. Following reformulation work, in 2019, we received a grant from the Cystic Fibrosis Foundation (CFF) to complete
preclinical studies with Colorado State University which further demonstrated the potential for MAT2501 in treating cystic fibrosis-associated
NTM lung infections. In November 2020, we received an additional grant from the CFF in the amount of 3.75 million USD to support
the continued development of MAT2501 through a comprehensive preclinical tox program and a single ascending dose (SAD) study in
healthy volunteers with our new and improved formulation of MAT2501. This most recent grant was based upon the positive preclinical
proof of concept data generated by Dr. Diane Ordway at Colorado State University in a rigorous mouse model of NTM infection in
mice with underlying CF disease.
MAT2203
Our
lead anti-fungal product candidate, MAT2203, is an application of our LNC platform delivery technology to a broad spectrum and
potent anti-fungal drug called amphotericin B. Traditionally, amphotericin B is an IV-administered drug used as a last resort
for treatment of systemic fungal infections resistant to triazoles and echinocandins, including resistant candidiasis, cryptococcal
meningoencephalitis, and aspergillosis. To date, there have been little to no reports of clinically observed drug-resistance to
amphotericin B, further bolstering the use of this compound as the most likely last resort treatment for fungal infections in
the foreseeable future. However, the use of amphotericin B is relatively limited because it is currently only available as an
IV-administered product and has documented history of severe toxicity (most notably nephrotoxicity). By utilizing our LNC platform
delivery technology to nano-encapsulate amphotericin B, there is now an opportunity for the drug to be administered orally with
targeted delivery to infected cells, which we believe may have fewer side effects than the currently available IV-formulations
of amphotericin B. Our LNC delivery of amphotericin B changes the bio-distribution, resulting in a higher level of the drug at
the site of infection and a lower level of free circulating amphotericin B. By reducing the amount of circulating drug, our LNC
platform delivery technology may reduce overall toxicity. Importantly, drug concentrations will be high only in target tissues
due to the migratory nature of activated cells to inflammatory regions. Based upon our studies to date, we believe MAT2203 has
the potential to offer improved safety and reduced toxicity and, as a result, we believe MAT2203 will be able to offer a categorically
different and improved formulation that delivers orally administered amphotericin B, directly to the target cell at the site of
infection. In collaboration with the NIH, in multiple studies, we have demonstrated in CM mouse models that our LNC-delivered
amphotericin B, following oral administration, can successfully cross the blood brain barrier to the site of infection in mice.
This demonstration provides important data indicating that our LNC platform delivery technology could become an important delivery
solution for a variety of CNS-based disorders and diseases.
We
believe that MAT2203 has the potential to become a best-in-class induction, consolidation, and maintenance therapy for the treatment
of CM in HIV patients by offering the following key benefits:
●
Potential
to treat resistant pathogens . We believe that MAT2203 has the potential to prevent and treat fungal infections caused
by drug-resistant fungi, including those resistant to existing azoles and echinocandins, due to amphotericin B’s fungicidal
(i.e., killing the fungi) nature and potency against resistant strains and the potential for our LNC platform delivery technology
to provide higher drug exposure early in the course of therapy.
●
Enabling
an all-oral therapy. CM has become the most common cause of adult meningitis in many parts of Africa, where cryptococcosis
now rivals tuberculosis in all-cause mortality. While long-term survival has improved with widespread use of antiretroviral
therapy in high-income countries, early mortality remains high. Early mortality rates are often ~ 70% in routine practice
where access to diagnostics or medications is limited or unavailable, intracranial pressure is uncontrolled, or in settings
where other barriers to the management of CM exist. IV administration of amphotericin B deoxycholate is not often possible
in resource-limited settings, even when it is available.
●
Shorter
and less costly hospital stays and lower outpatient costs . By providing physicians and patients with access to an orally
available, broad spectrum fungicidal agent in MAT2203, there is the potential to reduce hospital costs, which account for
over 70% of the overall treatment cost of invasive fungal infections.
10
The
FDA has granted MAT2203 designations for Qualified Infectious Disease Product, or QIDP, and Fast Track for the treatment of invasive
candidiasis and aspergillosis, for the prevention of invasive fungal infections in patients on immunosuppressive therapy, and
the treatment of cryptococcosis. We recently also received Orphan Drug Designation for MAT2203 for the treatment of cryptococcosis
and associated CM. The FDA may designate a product candidate as an orphan drug if it is intended to treat a rare disease or condition,
which is generally defined as having a patient population of fewer than 200,000 individuals in the United States, or a patient
population greater than 200,000 in the United States where there is no reasonable expectation that the cost of developing the
drug will be recovered from sales in the United States. The orphan drug designation provides eligibility for orphan drug exclusivity
in the United States upon FDA approval if a product that has orphan drug designation subsequently receives the first FDA approval
for a particular active ingredient for the disease for which it has such designation. For a product that obtains orphan drug designation
based on a plausible hypothesis that it is clinically superior to the same drug that is already approved for the same indication,
in order to obtain orphan drug exclusivity upon approval, clinical superiority of such product to this same drug that is already
approved for the same orphan indication must be demonstrated. Orphan drug exclusivity means that the FDA may not approve any other
applications, including an NDA, to market the same drug for the same indication for seven years, except in limited circumstances
such as if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient
quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. Similarly,
the FDA can subsequently approve a drug with the same active moiety for the same condition during the exclusivity period if the
FDA concludes that the later drug is clinically superior, meaning the later drug is safer, more effective or makes a major contribution
to patient care. Orphan drug designation also entitles a party to financial incentives such as opportunities for grant funding
towards clinical trial costs, a waiver from payment of user fees, an exemption from performing clinical studies in pediatric patients
unless the FDA requires otherwise by regulation, and tax credits for the cost of the clinical research. The QIDP designation,
provided under the Generating Antibiotic Incentives Now Act, or the GAIN Act, offers certain incentives for the development of
new antibacterial or antifungal drugs, including eligibility for Fast Track designation, priority review and, if approved by the
FDA, eligibility for an additional five years of marketing exclusivity. Fast Track designation enables more frequent interactions
with FDA to expedite drug development and review. Fast Track designation does not change the standards for approval, and we can
provide no assurances that we can maintain Fast Track designation for MAT2203 or that such designation will result in faster regulatory
review. The seven-year period of marketing exclusivity provided through orphan designation, if granted, combined with an additional
five years of marketing exclusivity provided by the QIDP designation positions MAT2203 with a potential for a total of 12 years
of marketing exclusivity to be granted at the time of FDA approval.
MAT2203
- Product Profile
MAT2203
is an orally-administered, LNC formulation of amphotericin B (a broad-spectrum fungicidal agent). Little to no clinical resistance
has been reported to date with amphotericin B as compared to the rapidly emerging drug resistance seen with other antifungal therapies.
Currently, IV administered amphotericin B is the only broad spectrum fungicidal; however, it has significant treatment-limiting
side effects, most notably nephrotoxicity. We believe that the ability to provide amphotericin B orally using our proprietary
and novel oral formulation comprising our LNC platform delivery technology, may offer a new and promising alternative for patients
and doctors.
The
data from animal toxicity studies for MAT2203 indicate a side-effect advantage over other amphotericin B formulations, which we
believe is based on two phenomena:
●
The
lipid- nanocrystal is a solid particle that does not significantly “leak” its drug content while circulating.
The particle releases its medication pay-load only when inside the target cells, and thus appears that the use of MAT2203
does not result in off-organ toxicities normally seen in the kidneys when using current formulations of amphotericin B.
●
Because
of this targeted approach, we have been able to increase the therapeutic window on a
mg/kg basis as compared to IV amphotericin B formulations. We have observed equivalent
efficacy at lower doses as well as been able to use oral doses of up to 10x the highest
tolerable IV dose in animal model studies.

Development
History of MAT2203 and Initial Target Indication
MAT2203
has been studied extensively in animal model studies of various fungal infections including invasive candidiasis, aspergillosis,
and CM.
In
a clinical Phase 1 single-dose, double-blind, dose-escalating, pharmacokinetic study of 48 healthy volunteers, oral MAT2203 was
observed to be well-tolerated with no serious adverse events reported, and without any observed nephrotoxicity. The most commonly
reported adverse events (AEs) were nausea and abdominal pain. None of the AEs were related to abnormal laboratory evaluations.
All treatment emergent adverse events (TEAEs) were mild except 1 instance of “upper respiratory tract infection” which
was moderate in a subject following 800 mg MAT2203. No AEs led to withdrawal. There were no serious AEs. There was one pregnancy
(subsequently determined that the conception date was 1 to 2 days prior to dosing) resulting in elective termination from the
study. More recently, in our Phase 2 trial of MAT2203 conducted by the NIH, four out of four enrolled patients suffering from
chronic refractory mucocutaneous candidiasis met their primary efficacy endpoint. One patient continues on treatment with no evidence
of kidney or other toxicity frequently associated with the use of amphotericin B.
In
October 2020, results from Phase 1 of the EnACT Study were published in the Journal of Antimicrobial Agents and Chemotherapy (C.
Skipper, et.al) which was a Phase 1 ascending-dose trial of MAT2203 administered at 1.0 g, 1.5 g, or 2.0 g per day in 4 to 6 divided
doses among HIV-positive survivors of cryptococcosis (n=9 per cohort). We assessed the tolerability of MAT2203, and the AEs associated
with MAT2203 treatment over three days. The second part of the Phase 1 trial assessed the tolerability of 1.5 grams/day (the 100%
tolerated dose) administered for seven days. In the singe-ascending dose part of the study, all subjects in the 1.5 g treatment
group received their full dose without vomiting (100% tolerability). The cohort receiving 1 g had 4 transient clinical AEs in
2 subjects. The cohort receiving 1.5 g had 7 clinical AEs in 1 subject. The cohort receiving 2 g had 20 clinical AEs in 5 subjects.
From a qualitative survey, 26 of 27 (96%) preferred their experience with MAT2203 over their prior experience with IV amphotericin
(AMB).
The
second, multiple dose cohort received 1.5 g/day for 1 week, which was the 100% tolerated dose, with 98.4% of doses taken. Overall,
5 clinical AEs occurred in this cohort of subjects without any observed kidney toxicity. Oral MAT2203 was well-tolerated when
given in 4 to 6 divided daily doses without the toxicities commonly seen with IV AMB.
Based
on the findings from Phase 1 of the EnACT Trial, 2.0 g was selected as the target dose for the induction phase of treatment and
1.5 g for the maintenance dose for Stage 1 of the study. Phase 2 of the trial is evaluating the safety, tolerability, and efficacy
of MAT2203 in approximately 100 HIV-infected patients with cryptococcal meningitis. Participants enrolled in the experimental
arm of each cohort received oral MAT2203 and flucytosine (5FC) in four separate stages and duration for induction therapy, using
the maximum tolerated dose of MAT2203 that was identified in the preceding Phase 1 Trial. The experimental arm receives MAT2203
through induction and maintenance therapy for a total of approximately 6 weeks. Participants randomized to the control arm in
each cohort receive the 2018 WHO recommended standard of care, which is IV AMB and 5FC, followed by fluconazole.
The
first cohort of EnACT has been completed. A key objective of Cohort 1 was to assess the safety and tolerability of oral MAT2203
while assessing efficacy. Ten participants were randomized to the experimental arm and 4 to the control arm. The study treatments
received are summarized in the following figure:
Patients
in the experimental arm received induction therapy with IV AMB (1 mg/kg/day) for the first five days, oral MAT2203 (2 g/day in
divided doses) from Day 5-14, and oral 5FC (100 mg/kg/day) for the first 14 days of treatment. Induction therapy was followed
by consolidation or maintenance therapy with oral MAT2203 (1.5 g/day) from Day 15 to Week 6, oral fluconazole (800 mg/day) from
Day 15 to week 10, followed by oral fluconazole (200 mg/day).
12
Efficacy
and safety data from Cohort 1 of the study were reviewed by an Independent Data Safety Monitoring Board (DSMB) which voted unanimously
to progress into the second cohort of patients in the EnACT Study.
Enrollment
in the second cohort of patients has begun and Cohort 2.
Cohort
2 (or Stage 2) of the EnACT Study is designed to assess the potential to treat CM infections with oral MAT2203 as a step-down
treatment during the induction phase of treatment immediately following only 2 days of IV amphotericin treatment, with continued
treatment with MAT2203 for up to 6 weeks during early maintenance treatment. We believe that the clinical benefit of step-down
treatment from IV amphotericin to oral MAT2203 will provide compelling clinical evidence of efficacy in treating this deadly infection
with our oral agent. We believe that this Cohort of patients will also provide key data to support the further advancement of
the EnACT Study to ultimately test the potential to treat CM infections with an all-oral amphotericin dosing regimen in subsequent
cohorts (Stages 3 and 4 below).
The
read-out for Cohort 2 is expected in the second half of 2021.
Antifungal
Market Opportunity
The
overall global antifungal market accounted for approximately $11.9 billion in 2018 and is expected to reach approximately $13.9
billion by 2026. In 2018, the global invasive fungal infection market was valued at more than $6 billion. This includes therapies
used as active treatment or prophylaxis (preventative) in the inpatient and outpatient setting, therapies used for the treatment
of hospitalized patients and therapies used for the treatment of patients who are being discharged from the hospital. We estimate
that, each year, there are over 1.5 million cases of invasive fungal infections caused by various species of Candida, Aspergillus
and Cryptococcus, the three most common invasive fungal pathogens, globally. The estimated incidence in the U.S. for
these conditions is approximately 46,000 for invasive candidiasis, 15,000 for invasive aspergillosis, and 3,700 for CM. For example,
aspergillosis-associated hospitalizations in the U.S. alone came at an estimated treatment cost of more than $1 billion. The rapid
progression of disease and high mortality rates (20% - 50%) associated with documented invasive fungal infections often result
in antifungal therapy being administered in suspected (unconfirmed) cases or as a preventative measure in patients at high risk.
Also, the increasingly widespread use of immune suppressive drugs as cancer chemotherapy or for organ transplantation or treatment
of autoimmune disease has resulted in an increasing population of patients at risk for invasive fungal infections. Furthermore,
the limited number of systemic antifungal drug classes, consisting of azoles, echinocandins and polyenes, and their extensive
use, has led to increased numbers of infections with drug-resistant strains. The Centers for Disease Control and Prevention (CDC)
has listed fluconazole-resistant Candida as a serious threat requiring prompt and sustained action and has also identified
a rise in echinocandin resistance, especially among Candida glabrata. In June 2016, the CDC issued an extraordinary alert
for healthcare facilities and providers to be on the lookout for patients with Candida auris , a multidrug resistant strain
with high mortality (approximately 60%). Almost half of C. auris isolates are multidrug resistant to two or more antifungal
classes (large majority resistant to fluconazole, 40% resistant to echinocandins). We believe this underscores the urgent need
for new agents with demonstrated activity against resistant strains and that can be administered with significantly less toxicity
and the potential to discharge patients earlier to reduce hospital stays and associated costs.
13
Physicians’
options for the treatment of fungal infections are limited by a lack of innovative therapies. Several factors have contributed
to the low rate of antifungal drug development, including a previously challenging regulatory environment that necessitated large
and costly clinical trials. As a result of this regulatory environment and other factors, the number of antifungals in development
has decreased, while anti-microbial resistance has increased.
MAT2501
MAT2501
is an oral, LNC formulation of the broad-spectrum aminoglycoside antibiotic agent amikacin, which utilizes our proprietary LNC
platform to achieve oral bioavailability, limit toxicity, and enable targeted delivery to sites of infection. Currently, amikacin
can only be delivered parenterally or through inhalation and is used to treat a variety of chronic and acute bacterial infections,
including both NTM infections and various multi-drug resistant gram-negative bacterial infections. IV and inhaled amikacin, however,
are associated with major side-effects including nephrotoxicity and ototoxicity (permanent loss of hearing) with long-term use.
We believe that MAT2501’s ability to orally deliver high levels of amikacin directly to the lung and without use-limiting
toxicity, distinguishes it from all available therapies and could provide an important solution for patients and physicians. We
are currently developing MAT2501 for the treatment of NTM lung disease, including infections in patients with CF. MAT2501 has
been designated as a Qualified Infectious Disease Product (QIDP) and as an Orphan Drug for the treatment of NTM by the US FDA.
NTM
lung disease is a chronic, debilitating condition arising from an NTM infection in the lungs and is associated with significant
patient morbidity and mortality. The signs and symptoms of NTM lung disease often overlap with the underlying lung conditions
that increase the risk for NTM, like cystic fibrosis, bronchiectasis, COPD, and asthma. The most common pathogens for NTM infections
in the United States are Mycobacterium avium complex (MAC), which accounts for more than 80% of all NTM infections in the
US. Patients with NTM lung infections frequently require lengthy hospital stays and prolonged courses of antibiotics to manage
their disease. The prevalence of human disease attributable to NTM has increased over the past two decades and is now growing
at more than 8% per year and is even more prevalent than tuberculosis in the US. In 2018, it was estimated that between 75,000
and 100,000 patients were diagnosed with NTM lung disease in the US alone.
Non-tuberculous
mycobacterium (NTM) infections are extremely difficult to treat, especially so in patients with cystic fibrosis (Eikani, et.
al ., 2018). The infecting organisms are frequently resistant to most antibiotics, and current treatment regimens require combination
therapies with highly toxic drugs for long periods of time, further complicated by challenges in delivering therapeutic levels
of these toxic drugs across plasma membranes of infected cells.
These
challenges are amplified in CF patients, with the thick buildup of pulmonary secretions that further impair treatment of infecting
organisms. Pulmonary infections represent the most frequent type of infection in CF patients, and are responsible for more than
90% of deaths in the CF population (Rowe SM, et.al . 2005). Mycobacterium avium complex (MAC) and Mycobacterium abscessus
complex (MABSC) are non-tuberculous mycobacterial species that have emerged in recent years as important opportunistic pathogens
frequently responsible for pulmonary infections in CF patients (Brode SK, et. al . 2014). Infections due to MAC and MABSC
are difficult to treat and to eradicate since these organisms are naturally resistant to most antibiotics. The recommended treatment
for MAC and MABSC pulmonary infections includes a combination of a macrolide (clarithromycin or azithromycin), an aminoglycoside
(amikacin), and an antimycobacterial antibiotic for MAC (rifampin and ethambutol), while MABSC many times requires intravenous
β-lactam (cefoxitin or imipenem) at least for 12 months (Floto RA, et. al. , 2016). The cure rate is only 25-40% in
the case of macrolide resistance, which is present in 40 to 60% of the isolates (Roux AL et. al ., 2015). Moreover, unsuccessful
eradication of MAC and MABSC is considered as a contraindication for lung transplantation by several CF centers, and significantly
restrict therapeutic options in severely ill patients. Therefore, more specific and active and less toxic antimicrobials are urgently
needed.

MAT2501
Previous and Ongoing Studies
The
most recent completed pre-clinical animal model studies testing the preclinical efficacy of MAT2501 were funded by a grant from
the Cystic Fibrosis Foundation (CFF). An additional grant was awarded from the CFF in February of 2020 to support the screening
of new optimized formulations of MAT2501 in collaboration with Diane Ordway, Ph.D. of Colorado State University (CSU). Most recently,
a CFF grant of $3.75 million was awarded to us in November 2020 to support the early development of MAT2501 through the end of
Phase 1. The recent grant from the CF Foundation was based upon the data generated by CSU and summarized below.
Preclinical
and Clinical Studies
The
Investigational New Drug (IND) application for MAT2501, was opened in January 2016 to investigate MAT2501 in the proposed indication
for treatment of non-tuberculosis mycobacterial (NTM) infections.
We
have conducted numerous repeat-dose non-clinical studies including a 28-Day rat study and 3 nonclinical studies in large animals
(2 with dog and 1 with dog and minipig). Data generated to date suggest no toxicity signals related to those observed with IV
amikacin.
We
have conducted to date a first-in-human Phase I study entitled: A Phase 1, Double-Blind, Placebo- Controlled, Single, Ascending
Dose Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of Encochleated Amikacin (CAMK/MAT2501) Following Oral Administration
in Healthy Adult Subjects. Safety was monitored through physical examinations, vital signs, 12-lead ECGs, audiometry tests, pupillary
reflex tests and clinical lab tests. No serious adverse events were reported in the study. Adverse events were tolerable and not
unexpected. There were no adverse events related to audiology assessments or ophthalmic pupillary reflex testing. A total of 36
subjects were entered into this study in three (3) cohorts (dosing of 12 subjects (9 active drug subjects and 3 placebo subjects
in each cohort). Doses tested were 200mg under fasted conditions, 400mg under fasted and fed conditions and 800mg under fed conditions.
One subject in high dose cohort (800 mg dose, fed condition) was discontinued early during the study as a result of gastrointestinal
issues possibly related to study drug. The study was completed in March of 2017 and the final clinical study report was submitted
to the IND in February of 2018.
MAT2501
(LNC Oral Amikacin) for the Treatment of NTM Infections in Mouse Models of CF
In
vivo chronic efficacy studies
MAT2501
was tested in in vivo experiments of NTM infections in CF mouse models. In the CF (B6CFTR tm1UNC /CFTR tm1UNC )
mice chronic model for CF, the CAMK was administered daily for each NTM species tested on each of the six NTM strains across two
tiers. Tier 1 included strains having a low drug resistance and Tier 2 included drugs that were resistant to macrolide antibiotics
(See Table 1).

Study
Design
Six
CF chronic model experiments were conducted i) to evaluate whole organ bacterial burden and ii) to evaluate whole organ pathology
and metabolic stability using hepatocytes from mice. Groups of CF mice were infected with mycobacterium avium (Ma) and mycobacterium
abscessus (Mabs) strains as described in Table 1. On day 2 after infection, 5 mice in each group were ethically euthanized to
quantify the initial bacterial burden. Treatment for the remaining animals began after 28 days of infection. Oral MAT2501 100
mg/kg QD, Oral MAT2501 100 mg/kg BID, untreated control and two positive controls (oral clarithromycin 250 mg/kg and subcutaneous
amikacin 150 mg/kg 3x/week) were administered for 8 weeks. After the drug treatment began, any effect the compound had on lung,
liver and spleen bacterial numbers and organ histology was assessed (CFU, pathology) at intermittent time intervals of treatment
(2, 4, 8, weeks of drug treatment) and compared to untreated concurrent control saline and clarithromycin 250 mg/kg and amikacin
150 mg/kg control values (Obregon A., et. al , 2015).

Conclusions
Oral
administration of MAT2501 safely and effectively treated Mycobacteria infections in a mouse model of Cystic Fibrosis.
●
Colony
counts showed that the oral administration of MAT2501 100 mg/kg resulted in CFU lung, spleen and liver counts that were lower
than those in mice receiving parenteral amikacin alone.
●
Colony
counts showed that the oral administration BID of MAT2501 resulted in CFU lung, spleen and liver counts that were significantly
lower than those in mice receiving clarithromycin alone.
●
The
lung pathology in cystic fibrosis mice infected with each of the NTM isolates evaluated in this study showed that lesions
were more numerous and larger in infected mice that were treated with clarithromycin or parenteral amikacin compared to the
smaller lesions after oral administration of MAT2501.
NTM
Treatment Guidelines and Limitations of Current Treatments
The
American Thoracic Society (ATS), European Respiratory Society (ERS), European Society of Clinical Microbiology and Infectious
Diseases (ESCMIID), and Infectious Diseases Society of America (IDSA) jointly sponsored the recent development of updated NTM
Treatment Guidelines in adults (Daley C, et.al , 2020). The guidelines recommend a standard NTM lung disease treatment with
a combination of 3-4 medications. These include Amikacin (or streptomycin), clarithromycin (or azithromycin), rifampin (or rifabutin),
and ethambutol. Amikacin is an important drug used for treatment of Mycobacterium abscessus pulmonary disease. Certain
combinations of antibiotics work better together because of their unique mechanisms of action that work in concert to eliminate
the infection. It is for this reason that sputum samples are qualified for precise identification of the species and sensitivity
testing of the microorganism. When treatment failures arise, another combination of antibiotics will be recommended depending
on the NTM strain.
Multiple
drug therapy in NTM lung disease can cause adverse effects, which leads to treatment discontinuation or patient nonadherence.
Current guidelines recommend monitoring for drug toxicity at repeat intervals. Gastrointestinal side effects with oral agents
are common. Due to severe gastrointestinal disturbance, the use of macrolides may require dose adjustment. Drug-induced hepatotoxicity
due to rifampin and other agents must be monitored by liver function tests and monitoring complete blood count when using rifampin
or tigecycline is recommended. Renal function testing is required with IV amikacin use due to its known renal toxicity liability,
an issue that we believe could be addressed with our novel targeted LNC oral formulation of amikacin, MAT2501. Due to the established
risk of otoxicity such as hearing loss, tinnitus, or vestibular toxicity, patients who receive IV amikacin or streptomycin need
to be educated regarding the signs and symptoms of toxicity with audiometry testing at the start of therapy and again on subsequent
visits with discontinuation, or a decrease in dose or frequency if signs suggestive of toxicity occur. There remains a significant
unmet clinical need for safer, yet potent, agents for the improved management of NTM lung disease. MAT2501 has the potential of
providing a safer and more targeted approach to the treatment of NTM disease.
The
early development plan for MAT2501 builds upon the preclinical proof of concept in vitro studies which have demonstrated
antibiotic activity against both sensitive and multidrug resistant strains M. abscessus and M avium. The planned Tox Program
will evaluate the optimized formulation of MAT2501 in a rigorous battery of studies to assess and characterize the safety profile
of MAT2501. The planned studies will support the safety package required to progress the development of MAT2501 into Phase 2 clinical
trials. These studies will carefully monitor the safety signals known to be associated with IV amikacin treatment (hearing loss
and kidney/renal safety). These studies will include:
●
28
rat toxicity study to assess any potential effects of MAT2501 on hearing and associated side effects
●
3-
and 9-month long-term safety study in dog to support longer-term dosing in clinical trials
16
These
GLP studies are planned to be initiated in the second half of 2021 and will commence following FDA review of the protocols for
the 3- and 9-month dog study, which will be submitted for review by Q3 2021.
A
Phase 1 SAD Study will also be conducted with the optimized formulation in parallel with the long-term tox study and is expected
to be initiated in Q4 2021 with final data available early 2022.
LYPDISO
Overview
LYPDISO
is a complex mixture of multiple long-chain omega-3 fatty acids, primarily eicosapentanoic acid (EPA) and docosapentanoic acid
(DPA) encapsulated in a delayed release soft gelatin capsule. Unlike currently approved pharmaceutical omega-3 products, all of
which have been repurposed following clinical failures in their originally intended indications, LYPDISO has been specifically
designed and developed to treat HTG in patients with cardiovascular and metabolic conditions. There are a number of existing FDA-approved
omega-3 products, including Lovaza®, Vascepa® and Epanova®, and this class of drugs has extensive evidence of safety
and well-documented clinical efficacy in lowering TGs in patients with HTG. Vascepa has also demonstrated the ability to achieve
meaningful reductions in cardiovascular risk based primarily upon achievement of elevated levels of EPA in the blood. We believe
that given LYPDISO’s enhanced bioavailability (as a free fatty acid rather than an ethyl ester) and its unique composition
(high EPA plus DPA), it can be differentiated from other existing products in the omega-3 class and have uniquely potent impacts
on TGs, but also a variety of other biomarkers, including achieving elevated levels of EPA in the blood.
Currently,
the only available route to an approval for TG-lowering with a prescription omega-3 drug is in severe hypertriglyceridemia (SHTG),
where patients have TG levels ≥ 500 mg/dL, and where TG-lowering is a well-accepted surrogate marker. Additionally, Vascepa
has been approved for cardiovascular risk reduction in patients at high cardiovascular risk with TGs ≥ 150mg/dL, based upon
its ability to achieve elevated levels of EPA in the blood. Our current development plan is via a 505(b)(2) regulatory pathway,
which allows us to rely, at least in part, on FDA findings of safety and/or effectiveness for a previously approved drug. Based
on prior written feedback received from the FDA in 2014, and additional verbal and written feedback from FDA in August of 2020,
we believe that a 505(b)(2) pathway is possible and appropriate for LYPDISO.
In
parallel with the preclinical and clinical studies necessary for FDA approval of LYPDISO, we also recently completed the ENHANCE-IT
study, a head-to-head crossover study of LYPDISO vs. Vascepa, which was intended to differentiate LYPDISO from the current leading
prescription omega-3 therapy. We believe that the results from ENHANCE-IT suggest potential for LYPDISO as a best-in-class prescription
omega-3 for cardiovascular risk reduction and we are pursuing a partnership to continue development of LYPDISO moving forward.
We do not plan on pursuing an indication for SHTG and have reallocated resources away from this clinical indication.
Hypertriglyceridemia
and Cardiovascular Disease
Triglycerides
and cholesterol are integral components of lipoproteins, the primary transport vehicle for lipids in the body. High levels of
triglyceride-rich lipoproteins are associated with a substantially increased risk of atherosclerotic cardiovascular disease, and
in the case of very high triglycerides (> 500 mg/dL), acute pancreatitis. HTG can be due to both genetic and environmental
factors, including obesity, a sedentary lifestyle, and high caloric diets. HTG is also tightly linked with comorbid conditions
such as diabetes, chronic renal failure, and nephrotic syndrome. It is estimated that over 25 million adults in the United States
have triglyceride levels ≥200 mg/dL and that more than 50 million adults in the United States have triglyceride levels ≥150
mg/dL. Additionally, approximately 4 million adults in the United States have very high triglyceride levels (≥500 mg/dL). The
prevalence of HTG is rapidly increasing in both the United States and throughout the world, as a direct consequence the growing
epidemic of obesity. Recent studies have confirmed that high levels of triglyceride-rich lipoproteins are an independent risk
factor for cardiovascular disease-related events such as myocardial infarction, ischemic heart disease, and ischemic stroke. Mixed
dyslipidemia refers to a condition in which patients have a combination of both elevated triglycerides (≥200mg/dl), and elevated
cholesterol levels. According to the National Cholesterol Education Program (NCEP), mixed dyslipidemia affects approximately 30
to 35 million Americans.
17
Multiple
epidemiological, clinical, and genetic studies suggest that patients with severe hypertriglyceridemia (TGs > 500 mg/dL)
are at a much greater risk for pancreatitis, a potentially life-threatening condition. Elevated TG levels are also strongly linked
to a higher risk for heart disease and stroke, especially so with low levels of high-density lipoprotein cholesterol (HDL-C) and/or
elevated levels of low-density lipoprotein cholesterol (LDL-C). Furthermore, the genes regulating both TGs and LDL-C are equally
strong predictors of CAD, unlike HDL-C which is not. Thus, TGs and TG-rich lipoproteins have come to be recognized as an important
factor contributing to Atherosclerotic Cardiovascular Disease (ASCVD).
There
are currently approximately 92 million (more than 1 out of every 3) adults in the United States with one or more types of cardiovascular
disease; an estimated 800,000 new or recurrent coronary events and 795,000 new or recurrent strokes occur each year. Heart attacks,
strokes and other cardiovascular events represent the leading cause of death and disability among men and women in western societies.
Recent
ASCVD Guidelines from The American Diabetes Association (ADA), the European Society of Cardiology/European Atherosclerosis Society
(ESC/EAS), National Lipid Association (NLA) and American Association of Clinical Endocrinology/American College of Endocrinology
(AACE/ACE) as well as a recent Scientific Advisory from the American Heart Association (AHA) have all advocated the use of an
omega-3 product (icosapent ethyl) in patients at high CV risk who have persistently high TGs (> 135 mg/dL) despite statin therapy.
Current
guidelines for the management of very high triglyceride levels (≥500 mg/dL) suggest that reducing triglyceride levels is the
primary treatment goal in these patients to reduce the risk of acute pancreatitis, while treating LDL-C remains an important secondary
goal. Other important parameters to consider in patients with very high triglycerides include levels of apolipoprotein B (apo
B), non-HDL-C, and very low-density lipoprotein cholesterol (VLDL-C).
Current
Treatment Options
The
dramatic rise in obesity over the last few decades is strongly linked to concomitant increases in population cholesterol and triglyceride
levels. Observational studies have highlighted the critical role that high cholesterol and high triglyceride levels (collectively,
“dyslipidemia”) have as a predictor of cardiovascular events. Accordingly, the introduction of new drugs and novel
mechanisms of action to lower the risk of cardiovascular events has become a priority. The initial treatment recommendation for
patients with dyslipidemia is typically a low-fat diet. If diet alone is not effective, dyslipidemia is then often treated with
statins, which account for approximately 80% of all dyslipidemia prescriptions. Statins as a class have been shown to not only
lower blood cholesterol levels, but have also been shown in multiple studies to reduce the risk of heart attacks, strokes, and
other adverse cardiovascular events. At present statins are utilized in almost 40% of patients with dyslipidemia in the United
States. The primary effect of statins is to reduce LDL-cholesterol, with only modest effects on triglycerides. Recognizing that
both cholesterol and triglycerides contribute to cardiovascular risk, and that statins alone are not always effective triglyceride
lowering drugs, the National Cholesterol Education Program panel recommends the use of additional therapies to lower triglyceride
levels in patients with SHTG. Fibrates, niacin, and omega-3-based medications have all been utilized to lower triglycerides levels.
The
overall treatment rate of patients with HTG has remained relatively low. It is estimated that less than ten percent of the adult
population with SHTG actually receives therapy beyond statins. Historically, fibrates such as gemfibrozil (Lopid) and fenofibrate
(Tricor or Trilipix) were leading treatments for HTG. However, due to their inability to establish clinical outcome benefits and
their limited compatibility with statin therapy, fibrate utilization has remained relatively low and is currently declining. Other
niacin-containing products used to treat SHTG have not been able to establish additional outcome benefits beyond statin treatment
alone, and their use is also declining. In patients with SHTG, many of whom are already receiving a statin, first-line drug therapy
is often a prescription omega-3 product, which have been shown to reduce triglycerides in the range of 20%-45%.
18
The
global prescription omega-3 market has been growing steadily over the last two decades; we estimate the market currently is approaching
$2 billion in global sales. The leading omega-3 prescription pharmaceutical products currently approved for the treatment of HTG
are Glaxo Smith Kline’s Lovaza (omega-3-acid ethyl esters, an omega-3 mixture containing mostly EPA and DHA, originally
approved in the US in 2004, branded as Omacor in the rest of the world), Amarin’s Vascepa (an ethyl ester formulation of
primarily EPA), approved in 2014 in the United States, Omacor and Seacor, (which are very similar to Lovaza and marketed in Europe);
and Mochida Pharmaceutical’s Epadel (98% ethyl eicosapentaenoate), an ethyl ester formulation of EPA, the leading Japanese
omega-3 product. In addition, Astra Zeneca’s omega-3, Epanova, a free fatty acid formulation of EPA and DHA was approved
in the US in 2016 but has not been launched. Until recently, all prescription omega-3 products in the US were only approved for
SHTG, but in December of 2019 Vascepa was approved in the US for the reduction of cardiovascular risk in high-risk patients with
TGs > 150 mg/dL despite statin therapy. This approval was based upon data generated in a large, multi-year, multi-center outcomes
study of Vascepa called REDUCE-IT.
The
REDUCE-IT study was a multicenter, randomized, double-blind, placebo-controlled trial of Vascepa in patients at high cardiovascular
risk with elevated triglycerides despite statin therapy. A total of 8,179 patients with established cardiovascular disease or
with diabetes and other risk factors, who had been receiving statin therapy and who had fasting TGs of 135 to 499 mg/dL and LDL-C
levels of 41 to 100 mg/dL were randomized to 2 g of Vascepa twice daily (total daily dose 4 g) or placebo (mineral oil). The primary
endpoint was a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization,
or unstable angina. The key secondary end point was a composite of cardiovascular death, nonfatal myocardial infarction, or nonfatal
stroke. Median follow-up was 4.9 years.
In
the 8,179 patients enrolled (71 % secondary prevention, 29% primary prevention) primary endpoints occurred in 17.2% of the Vascepa-treated
patients and 22.0% of the placebo patients (HR 0.75; p<0.001); corresponding key secondary end point event rates were 11.2%
and 14.8%, respectively (HR 0.74; p<0.001). There were also significant reductions with Vascepa in the rates of fatal/non-fatal
MI (HR 0.69; p<0.001), urgent/emergent coronary revascularization (HR 0.65; p<0.001), cardiovascular death (HR 0.80; p=0.03)
hospitalization for unstable angina (HR 0.68; p=0.002) and fatal/non-fatal stroke (HR 0.72; p=0.01). From a safety standpoint,
a slightly more patients in the Vascepa group were hospitalized for atrial fibrillation or flutter (3.1% vs. 2.1%, p=0.004), and
serious bleeding events were slightly more frequent with Vascepa (2.7% vs 2.1%, p = 0.06).
One
very important piece of information to emerge from REDUCE-IT was the importance of EPA blood levels. In REDUCE-IT, EPA levels
were the only biomarker that was significantly correlated with clinical benefit, across a wide spectrum of cardiovascular outcomes.
Changes in TGs, LDL-C, non-HDL, apoB and CRP were all not predictive of better outcomes with Vascepa in the REDUCE-IT trial. Importantly,
there was a significant continuous relationship between EPA levels and outcome for the primary and key secondary endpoints. The
higher the EPA level, the lower the hazard ration for adverse events, and the better the outcomes in REDUCE-IT.
LYPDISO
Development History and Plan
We
completed the first preclinical studies of LYPDISO in 2013 with others completed during 2014. In 2015, we announced results from
an open-label head-to-head PK/PD Trial of LYPDISO against Vascepa in patients with elevated triglyceride levels. This crossover
study demonstrated superior bioavailability of LYPDISO, along with greater efficacy in reducing serum triglycerides, total- and
non-HDL-cholesterol, apolipoprotein CIII and PCSK9 levels. Forty-two patients were treated with 4 grams/day of LYPDISO or Vascepa
for 14 days, followed by a 5-week wash-out period and crossed over to the other treatment for another 14 days of treatment. Study
subjects were required to have fasting TG levels of 200-400 mg/dl without lipid altering therapy, or fasting TG levels of 200
to 350 mg/dL if they were on stable-dose statin monotherapy. Forty patients completed both arms of the trial. In comparison to
Vascepa, treatment with LYPDISO provided significantly greater reductions in TGs, very low-density lipoprotein cholesterol (VLDL)
non-HDL cholesterol, total cholesterol, apolipoprotein AI, apolipoprotein CIII, and PCSK9. In additional, LYPDISO achieved significantly
higher blood levels of EPA.
19
Following
initial announcement of these data in 2015, due primarily to cardiovascular regulatory and commercial market conditions, as well
as limited financial resources, we postponed further development of LYPDISO until such time as data could became available from
REDUCE-IT. The REDUCE-IT data were announced in the fall of 2018, and as previously noted, there was robust clinical benefit in
8,000+ higher-risk patients with elevated triglycerides despite adequate LDL-C control with statins, with no statistical heterogeneity
between the primary and secondary prevention cohorts. Following the release of these data, we promptly re-activated our development
program for LYPDISO.
The
development program for LYPDISO was initially designed to (a) complete studies required for approval for an initial indication
to treat SHTG and, (b) complete additional trials to demonstrate the differentiation of LYPDISO vs. other approved omega-3 products
while creating the potential for subsequent label enhancement in a broader dyslipidemic patient population. The IND was reactivated
in the second quarter of 2019.
During
the second half of 2019 and the first quarter of 2020 we completed a 28-day preclinical comparative bridging toxicology study,
initiated and competed the in-life portion of an additional 90-day preclinical comparative bridging toxicology study, and initiated
and completed the clinical dosing for a comparative 4-way crossover clinical bioavailability study versus Lovaza in 36 healthy
volunteers. Lovaza was identified as the reference-listed drug under Section 505(b)(2) to FDA as part of the regulatory strategy
for approval of LYPDISO. The comparative bioavailability study to Lovaza involved an open label, single-dose, randomized, 4-way
crossover comparison of 4g of LYPDISO to 4g of Lovaza, under both fasted and fed conditions (high-calorie, high-fat breakfast).
Treatments were administered with at least 14 days between each dosing. Plasma free and total EPA, DPA and DHA were measured at
baseline and at specified timepoints up to 48-hours post-dose to assess bioavailability. Key areas of interest were baseline-free
adjusted free and total EPA (primary) and baseline-adjusted free and total DPA (secondary). Under fasted conditions, baseline-adjusted
total EPA and total DPA were substantially higher for LYPDISO compared with Lovaza. Similar findings were noted for free EPA and
free DPA. Under fed conditions, the absorption of Lovaza improved substantially, while that of LYPDISO improved slightly. Total
omega-3 levels (EPA + DPA + DHA) were approximately 50-60% higher with LYPDISO than with Lovaza after a high fat meal. Given that
in the fasted state LYPDISO was very well absorbed, with only a minimal food effect, whereas Lovaza was poorly absorbed unless
taken with a high fate meal, this indicated that the free fatty acid formulation of LYPDISO provided improved absorption with
a minimal food effect and without the need for a high fat meal for effective absorption. Key endpoints and assessments include
PK parameters (e.g., AUC, C max , T max , t 1/2 ) for total EPA, DHA and DPA and comparison of PK parameters
for LYPDISO in the fasted and fed (high fat meal) state.
In
August of 2020 we held an End-of-Phase 2 Meeting with FDA to review the results of the preclinical and comparative bioavailability
studies, and to discuss issues related to an approval in SHTG. The FDA provided feedback that: 1) with these preclinical and comparative
bioavailability data in-hand, a 505(b)(2) registration pathway was reasonable; 2) a single placebo-controlled Phase 3 trial would
likely be sufficient to establish efficacy in SHTG, and 3) the necessary safety database for approval could be supplement with
other patients, including patients with SHTG.
In
parallel with the preclinical and clinical studies necessary for FDA approval, we have also recently completed the ENHANCE-IT
study, an additional clinical study intended to differentiate LYPDISO from Vascepa, widely considered the leading prescription
omega-3 drug. ENHANCE-IT was a randomized, open-label, parallel-group, crossover study designed to assess and compare the effects
of LYPDISO and Vascepa on lipid markers and blood omega-3 levels. It included 100 adult men and women with elevated triglycerides
(150-499 mg/dL); approximately 58% of study subjects had TGs ≥ 200 mg/dL. The study protocol involved two 28-day treatment
periods, with a washout period of at least 28 days between treatments and was conducted at 8 sites in the U.S. LYPDISO and Vascepa
were each given as 2g twice daily with food in accordance with the approved Vascepa labeling. Baseline and post-treatment measurements
included triglycerides, Total-, LDL-, VLDL-, HDL- and non-HDL cholesterol, apolipoproteins A1, B and C3 and PCSK9, as well as
hs-CRP. An additional important endpoint was omega-3 blood levels, including EPA, DPA, DHA and total levels for both treatment
periods. The primary endpoint in ENHANCE-IT was the percent change from baseline to end-of-treatment in plasma triglycerides.
The first subject as randomized in June of 2020, enrollment was completed by the end of August, last-patient, last-visit was at
the end of November and the database was locked in mid-January 2021.
20
In
February 2021 we announced topline data from the ENHANCE-IT trial. Two analysis populations were prespecified in the statistical
analysis plan: a pharmacodynamic (PD) population (94 patients), and a per-protocol (PP) population (82 patients). The PD population
included all subjects for whom estimation of pharmacodynamic parameters was possible for both treatment periods, regardless of
study drug compliance. The PP population included patients from the PD population, with the added stipulation of at least 80%
compliance with study medications (verified by pill counts), with no clinically important protocol violations or deviations. The
PP population group was expected to have less variability due to poor study drug compliance, and to provide a more accurate representation
of how each study drug (LYPDISO or Vascepa) would perform when taken as directed.
The
topline results from ENHANCE-IT were as follows:
●
The
primary endpoint (% change in TG from baseline) was numerically greater with LYPDISO vs. Vascepa (21.9% vs. 15.7%) but did
not meet statistical significance in the prespecified PD population. Statistical significance as achieved in the PP population
(20.9% vs. 13.8%).
●
Plasma
EPA concentrations, absolute change from baseline and % change from baseline were all significantly higher with LYPDISO than
with Vascepa, in both the PD and PP populations (46% relative percent increase change from baseline EPA with LYPDISO vs. Vascepa).
●
There
were also significant reductions in hs-CRP with LYPDISO as compared with Vascepa, suggesting the potential superior anti-inflammatory
impact of LYPDISO.
●
There
were no serious adverse events reported and no dropouts related to study drug adverse events.
These
results provided important information about the potential role of LYPDISO in the management of patients with elevated triglycerides
and cardiovascular disease and highlighted the differentiation from Vascepa and generic copies of Vascepa in the omega-3 class.
The results of ENHANCE-IT suggest meaningful opportunities for LYPDISO as a best-in-class prescription omega-3 product for cardiovascular
risk reduction. Given the significant time and cost associated with cardiovascular outcomes clinical trials, we have initiated
a process to identify a partner to advance development of LYPDISO. We have allocated resources away from a Phase 3 program in
SHTG and will focus our internal resources primarily on advancement of our LNC platform delivery technology.
21
Strategic
Collaborations Using LNC Platform Delivery Technology
We
believe our LNC platform delivery technology can be used to reformulate a wide variety of molecules and drugs which, (i) require
delivery technology to effectively protect molecules and drugs in the body and could benefit from efficient delivery and cellular
uptake by target cells, and (ii) are currently only available in IV formulations or, (iii) otherwise experience significant toxicity-related
adverse events. We have tested a range of pharmaceutical compounds reformulated by our LNC platform delivery technology in proof-of-concept
animal studies, including oligonucleotides (mRNA, siRNA, DNA plasmids), vaccines, anti-inflammatory agents, NSAIDs and atovaquone.
We intend to pursue opportunities to develop products, either alone or in partnership with other pharmaceutical or biotech companies,
related to this technology and this remains a key part of our strategy to maximize the value of this unique and disruptive lipid-crystal
nanoparticle delivery technology.
In
January 2019 we announced a research evaluation with an undisclosed top global pharmaceutical company aimed to evaluate synergistic
effects of our LNC platform delivery technology with our partner’s nucleic acid polymer technology. Formulations will be
developed using our LNC platform delivery technology which enables the development of a wide range of difficult-to-deliver molecules.
Promising formulations will be tested in in vitro and in vivo preclinical studies. For competitive reasons, the
agreement stipulates certain confidential provisions, including the pharmaceutical company’s identity, the therapeutic molecule(s),
the intended targets and the financial terms of the agreement.
In
May 2019 we announced a research collaboration with ViiV Healthcare, a global specialist HIV company established by GlaxoSmithKline
and Pfizer dedicated to delivering advances in the treatment and care of people living with HIV or who are at risk for developing
HIV. As part of this collaboration, formulations of select antivirals will be developed using our LNC platform delivery technology.
Promising formulations will be tested in in vivo preclinical studies to identify a lead LNC antiviral formulation to take forward
in development. Due to the global pandemic, progress on this program has been limited due to competing ViiV Healthcare priorities.
In
December 2019, we announced a feasibility collaboration with Genentech, a Roche company, to evaluate formulations of a number
of Genentech compounds utilizing our LNC platform delivery technology. During 2020 we made progress in formulating two molecules
from this collaboration and continue to work with Genentech to evaluate these formulations and plan for additional preclinical
studies.
In
December 2020, we announced a collaboration with the National Institute of Allergy and Infectious Diseases (NIAID) to develop
oral formulations of Gilead’s remdesivir, which is currently only available as an intravenous therapy in the fight against
COVID-19. We believe the attributes of our LNC platform technology will allow for oral bioavailability and efficient intracellular
delivery. We have begun formulating remdesivir and preparing to deliver formulations to NIAID for in vitro preclinical
studies in COVID-19 models. If successful, the formulations will proceed to in vivo testing later in 2021.
We
continue to evaluate additional potential strategic collaborations with other interested biotech and pharmaceutical partners.
These early stage, proof-of-concept evaluations could provide an efficient, less expensive pathway to create numerous strategic
verticals in areas of innovative medicine while capitalizing on the development expertise and financial resources of well-established
pharmaceutical and biotech companies. Data from these evaluations could position us as a licensor of our LNC platform delivery
technology to numerous strategic partners better positioned to absorb the risks and costs of drug development while allowing our
company to become a royalty aggregator with the potential to generate upfront license, milestone and royalty payments as we maximize
the value of the overall LNC platform delivery technology.

Exclusive
License Agreement with Rutgers University
Through
our acquisition of Aquarius Biotechnologies Inc., we acquired a license from Rutgers University for the LNC platform delivery
technology. The Amended and Restated Exclusive License Agreement between Aquarius and Rutgers, The State University of New Jersey
(successor in interest to the University of Medicine and Dentistry of New Jersey) provides for, among other things, (1) a license
issue fee of $25,000 paid upon execution, (2) an increased equity interest in the company from 5% to 7.5% of Aquarius (prior to
our acquisition of Aquarius in the Aquarius Merger), (3) royalties on a tiered basis between low single digits and the mid-single
digits of net sales of products using such licensed technology, (4) a one-time sales milestone fee of $100,000 when and if sales
of products using the licensed technology reach the specified sales threshold and (5) an annual license fee of initially $10,000,
increasing to $50,000 over the term of the license agreement. We also agreed to assume the responsibility to pay required patent
prosecution and maintenance fees covering the technology.
Unless
otherwise terminated by either party, the term of the license, on a country-by-country basis, shall be the longer of 7-1/2 years
from the date of first commercial sale of a product in a country using the licensed technology or until the expiration of the
last-to-expire patent rights licensed under the agreement, whichever is longer. Rutgers has the right to terminate the license
agreement if we have not commenced commercial sales of at least one product using the licensed technology within nine years of
the effective date of the license agreement.
Intellectual
Property
The
proprietary nature of, and protection for, our product candidates and our discovery programs, processes and know-how are important
to our business. We will seek to protect our products and associated technologies for their manufacturing and development through
a combination of patents, trade secrets, proprietary know-how, FDA exclusivity and contractual restrictions on disclosure. Our
policy is to pursue, maintain and defend patent rights and to protect the technology, inventions and improvements that are commercially
important to the development of our business. Our success will significantly depend on our ability to obtain and maintain patent
and other proprietary protection for commercially important technology and inventions and know-how related to our business, defend
and enforce our patents, preserve the confidentiality of our trade secrets and operate without infringing the valid and enforceable
patents and proprietary rights of third parties. We also rely heavily on know-how and continuing technological innovation to develop
and maintain our proprietary position.
Matinas-Owned
Intellectual Property Relating to LYPDISO
We
have sought patent protection in the United States and internationally for our LYPDISO discovery program, and any other inventions
to which we have rights, where available and when appropriate. Our policy is to pursue, maintain and defend patent rights, whether
developed internally or licensed from third parties, and to protect the technology, inventions and improvements that are commercially
important to the development of our business.
Our
current patent portfolio relating to LYPDISO is comprised of two issued U.S. patents and one issued foreign patent in Australia.
The issued patents cover the Company’s proprietary methods relating to triglyceride levels, total cholesterol, VLDL-cholesterol
or apolipoprotein C-III by administering a pharmaceutical composition comprising omega-3 fatty acids including eicosapentaenoic
acid (EPA) and docosapentaenoic acid (DPA). These patents provide important protection to LYPDISO through 2033. In addition, we
have eight additional patent applications across four patent families covering the oil composition for LYPDISO, other omega-3
fatty acid compositions, as well as formulations of LYPDISO and similar formulations. All of these filed patent applications also
comprise methods of use of such oil compositions and formulations. Any patents that may issue from these filed United States patent
applications and their counterpart international application covering the LYPDISO drug substance, formulation, and methods for
use in treatment would extend protection until at least 2033.
Exclusively
Licensed and Matinas-Owned Intellectual Property Relating to Our Proprietary LNC Platform Delivery Technology and MAT2203
The
patents and patent applications that we exclusively license from Rutgers University provide patent protection for the proprietary
chemistry technology used in our process to make our lipid nanocrystal and geodate cochleates and formulate the active pharmaceutical
ingredients delivered inside this delivery technology, as in MAT2203, our lead product comprising the LNC platform delivery technology.
Pursuant to our license agreement, we acquired rights to a portfolio that currently includes 2 pending applications and 30 issued
U.S. and foreign patents, including 24 patents issued within the last 5 years, which extends patent protection until at least
2033. In addition, we have over 20 Matinas-owned pending patent applications filed both in the United States and in foreign jurisdictions
within the past 5 years. We have chosen to file these patent applications in selected foreign markets that we consider important
for our product candidates. These international markets generally include Europe, China, India, Brazil, Russia, Canada, Japan,
Korea, Australia and Mexico. These pending patent applications can extend patent protection through 2040. This patent portfolio
covers our LNC platform delivery technology which covers a broad spectrum of technology, including amphotericin B LNCs, geodate
LNCs, methods of delivering nutrients or biologically relevant molecules to a host using LNCs, LNC vaccine compositions and protein-lipid
vesicles, small interfering RNA LNCs, methods of enhancing the LNC encapsulation of hydrophilic molecules, LNCs made with low
purity soy phosphatidylserine, methods of treating Mycobacterial infections, and methods of treating cryptococcus infections.
23
We
cannot be sure that patents will be granted with respect to any of our pending patent applications or with respect to any patent
applications we may own or license in the future, nor can we be sure that any of our existing patents or any patents we may own
or license in the future will be useful in protecting our technology. For this and more comprehensive risks related to our intellectual
property, please see “Risk Factors—Risks Relating to Our Intellectual Property and Regulatory Exclusivity.”
In
addition to patents, we rely on trade secrets and know-how to develop and maintain our competitive position. For example, significant
aspects of our proprietary LNC platform delivery technology as well as the manufacture of certain intermediates utilized in LYPDISO,
as well as our soft gelatin capsule formulation, are based on unpatented trade secrets and know-how. Trade secrets and know-how
can be difficult to protect. We seek to protect our proprietary technology and processes, in part, by confidentiality agreements
and invention assignment agreements with our employees, consultants, scientific advisors, contractors and commercial partners.
These agreements are designed to protect our proprietary information and, in the case of the invention assignment agreements,
to grant us ownership of technologies that are developed through a relationship with a third party. We also seek to preserve the
integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and
electronic security of our information technology systems. While we have confidence in these individuals, organizations and systems,
agreements or security measures may be breached, and we may not have adequate remedies for any breach. In addition, our trade
secrets may otherwise become known or be independently discovered by competitors. To the extent that our contractors use intellectual
property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions.
We
also plan to seek trademark protection in the United States and outside of the United States where available and when appropriate.
We intend to use these registered marks in connection with our pharmaceutical research and development as well as our product
candidates.
Competition
The
biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense competition and a strong
emphasis on proprietary products. We face competition from many different sources, including commercial pharmaceutical and biotechnology
enterprises, academic institutions, government agencies and private and public research institutions. Many of these companies
have far greater human and financial resources and may have product candidates in more advanced stages of development and many
will reach the market before our product candidates. Competitors may also develop products that are more effective, safer or less
expensive or that have better tolerability or convenience.
LYPDISO
Our
competitors, both in the United States and abroad, include large, well-established pharmaceutical and generic companies, specialty
and generic pharmaceutical sales and marketing companies, and specialized cardiovascular treatment companies. GlaxoSmithKline
plc currently sells Lovaza ® , a prescription-only omega-3 fatty acid indicated for patients with SHTG, which was
approved by FDA in 2004 and has been on the market in the United States since 2005. Multiple generic versions of Lovaza are available
in the United States. Other large companies with competitive products include AbbVie, Inc., which currently sells Tricor ®
and Trilipix ® for the treatment of SHTG and Niaspan ® , which is primarily used to raise high-density
lipoprotein cholesterol, or HDL-C, but is also used to lower triglycerides. Multiple generic versions of Tricor, Trilipix and
Niaspan are also available in the United States. In 2012, Amarin Corporation received an approval to market its prescription-only
omega-3 ethyl ester called Vascepa® for the treatment of SHTG. In December of 2019 Vascepa was approved in the US for the
reduction of cardiovascular risk in high-risk patients with TGs > 150 mg/dL despite statin therapy. In January of 2021, the
European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) recommended approval for Vazkepa
(Vascepa) in the EU for a similar indication. Approval of Vazkepa is expected in the second quarter of 2021.
24
In
addition, in May 2014, Epanova ® (omega-3-carboxylic acids) capsules, a free fatty acid form of omega-3 (comprised
of 55% EPA and 20% DHA), was approved by the FDA for patients with SHTG. Epanova was developed by Omthera Pharmaceuticals, Inc.,
and is now owned by AstraZeneca Pharmaceuticals LP (AstraZeneca). To date, AstraZeneca has not launched Epanova in the United
States or in any other territory around the world but did conduct the STRENGTH study (a long-term outcomes study to assess ST atin
R esidual risk reduction with E pa N ova in hi G h cardiovascular risk patien T s with H ypertriglyceridemia).
STRENGTH was a randomized, double-blind, placebo-controlled (corn oil), parallel group design study that enrolled approximately
13,000 patients with HTG and low HDL and high risk for cardiovascular disease, randomized 1:1 to either corn oil plus statin or
Epanova plus statin, once daily. In January 2020, following the recommendation of an independent data monitoring committee, AstraZeneca
decided to end the STRENGTH trial due to a low likelihood of Epanova having any demonstrable benefit in the study. Final results
were published in November of 2020.
In
addition, in March 2017, Kowa Research Institute (a subsidiary of the Japanese company Kowa Co., Ltd.) initiated a Phase 3 cardiovascular
outcomes trial titled PROMINENT, examining the effect of pemafibrate in reducing cardiovascular events in Type II diabetic patients
with HTG. Kowa Research Institute has publicly estimated study completion in May 2022, and if successful, US regulatory approval
is estimate mid-2023.
During
2018, two outcomes studies were completed of omega-3 mixtures which both failed to achieve their primary endpoints of cardiovascular
risk reduction and two meta-analyses were published showing that omega-3 mixtures are not effective in lowering cardiovascular
risk. Results of these failed outcomes studies and analysis, while not done with LYPDISO, may negatively affect utilization of
LYPDISO, if approved. For example, the VITamin D and OmegA-3 TriaL (VITAL), failed to achieve its primary endpoint of lowering
cardiovascular events. VITAL was an NIH funded randomized double-blind, placebo-controlled, 2x2 factorial trial of 2000 IU per
day of vitamin D3 and 1 gram per day of omega-3 fatty acid mixture supplementation (Lovaza) for the primary prevention of cancer
and cardiovascular disease in a nationwide US cohort of 25,874 adults not selected for elevated cardiovascular or cancer risk.
Likewise, in 2018, results from A Study of Cardiovascular Events iN Diabetes (ASCEND) trial were released and showed negligible
results for omega-3 fatty acid mixtures 1 gram daily. ASCEND was a British Heart Foundation funded 2x2 factorial design, randomized
study to assess whether aspirin 100 mg daily versus placebo and separately, omega-3 fatty acid mixtures 1 gram daily versus placebo,
reduce the risk of cardiovascular events in a nationwide UK cohort of over 15,000 individuals with diabetes who do not have atherosclerotic
cardiovascular disease. In a meta-analysis, presented in 2018 by the Cochran Foundation and separately as published in JAMA, additional
omega-3 studies were evaluated. Similar to the VITAL and ASCEND studies, most of the studies in these omega-3 meta-analyses were
of omega-3 mixtures, including DHA, and most were studies of relatively low doses of omega-3 as is associated with dietary supplementation
and/or they studied relatively low risk patient populations. The exception was the JELIS study, conducted in Japan, of highly
pure EPA which showed a positive outcome benefit but had significant limitations in its application to a wider population. The
negative results from such omega-3 mixture studies could create misleading impressions about the use of omega-3s generally, including
LYPDISO, despite the unique combination of active ingredients in LYPDISO and its higher dose regimen.
MAT2203
and MAT2501
Although
we believe that our proprietary LNC platform delivery technology, experience and knowledge in our areas of focus provide us with
competitive advantages, these potential competitors could reduce our commercial opportunities. For many of our product candidates,
we anticipate facing competition from other products that are available on a generic basis and offered at low prices. Many of
these generic products have been marketed by third parties for many years and are well accepted by physicians, patients and payers.
We
believe that MAT2203 and MAT2501 and any other development candidate we may pursue in the future using our proprietary LNC platform
delivery technology, paralleled with our scientific and development expertise in the field of drug delivery, provide us with competitive
advantages over our peers. However, we face potential competition from various sources, including larger and better-funded pharmaceutical,
specialty pharmaceutical, and biotechnology companies, as well as from generic drug manufacturers, academic institutions, governmental
agencies and public and private research institutions.
25
MAT2203
will primarily compete with antifungal classes approved for the treatment of fungal and mold infections, which include
polyenes, azoles and echinocandins. The approved branded therapies for these indications include Cancidas (caspofungin, marketed
by Merck & Co.), Eraxis (anidulafungin, marketed by Pfizer, Inc.), Mycamine (micafungin, marketed by Astellas Pharma US, Inc.),
Diflucan (fluconazole, marketed by Pfizer, Inc.), Noxafil (posaconazole, marketed by Merck & Co.), Vfend (voriconazole, marketed
by Pfizer, Inc.), Sporanox (itraconazole, marketed by Jansen Pharmaceuticals, Inc.), Cresemba (isavuconazole, marketed by Astellas
Pharma US, Inc.), Ambisome (liposomal amphotericin B, marketed by Astellas Pharma US, Inc.) Abelcet (lipid complex amphotericin
B, marketed by Sigma Tau Pharmaceuticals Inc.) and amphotericin B deoxycholate (marketed by X-Gen Pharmaceuticals, Inc.). There
currently are and may be more generic versions of these products available at the time of MAT2203 market approval, which will
create added competition. In addition to approved therapies, we expect that MAT2203 may compete with product candidates that we
are aware of in clinical development by third parties, such as SCY-078 (being developed by Scynexis, Inc.), rezafungin acetate
(being developed by Cidara Therapeutics, Inc.) and certain products being developed by Viamet Pharmaceuticals Holdings, LLC, Vical
Incorporated and F2G, Ltd.
MAT2501
will primarily compete with aminoglycosides indicated for the treatment of NTM lung infections and will include Arikayce®,
an inhaled formulation of amikacin (marketed by Insmed) and IV amikacin (Amikin; marketed by Bristol Myers Squibb) as well as
a number of generic manufacturers of IV amikacin.
Manufacturing
We
currently engage with multiple third-party manufacturers to supply us with certain of the intermediates used in LYPDISO and an
additional manufacturer to formulate a third intermediate and supply us with the final drug form. We have an additional manufacturer
which fills and provides our final LYPDISO capsules. If any of these manufacturers should become unavailable to us for any reason,
we have identified a number of potential replacements, although we might incur some delay in qualifying such replacements. We
expect to add additional suppliers and manufacturers for both the intermediates and final LYPDISO drug product as we advance LYPDISO
further into clinical development.
We
currently lease and operate in-house manufacturing capabilities for our lead LNC platform delivery technology product candidate,
MAT2203, MAT2501, and for our LNC platform discovery programs in the gene therapy and vaccine spaces. While sufficient to produce
the clinical supplies of product necessary to conduct our ongoing clinical trials and potentially early commercialization of MAT2203
and MAT2501, we may need to expand our internal manufacturing capabilities in the future. If we are not able to retain our current
manufacturing facilities and if we do not develop additional in-house manufacturing capability for our MAT2203, MAT2501 and product
candidates sufficient to produce product for commercialization of these products, we will need to develop relationships with third-party
manufacturers for the manufacture of our product candidates which could be time consuming and expensive. We are in the process
of identifying a third-party contract manufacturer for MAT2203 and other products derived from our LNC platform technology.
There
are a number of potential third-party suppliers for amphotericin B, the generic active pharmaceutical ingredient in our lead clinical
stage product candidate – MAT2203 and for amikacin, the generic active pharmaceutical ingredient in our preclinical LNC
product candidate – MAT2501. Although to date we have not entered into formal supply agreements to secure sufficient supply
of amphotericin B or amikacin to support our clinical programs for MAT2203 or MAT2501, we believe we will be able to secure supply
of amphotericin B and amikacin to support our clinical programs for MAT2203 and MAT2501 and from one or more third-party suppliers.
As we move through development for our product candidates, we expect to enter into long term supply arrangements for key active
pharmaceutical ingredients.
Sales
and Marketing
We
currently do not have any sales and marketing infrastructure. We plan to retain U.S. marketing and sales rights or co-promotion
rights for our product candidates for which we receive marketing approvals, particularly in situations where it is possible to
access the market through a focused, specialized sales force. For situations in which a large sales force is required to access
the market, and with respect to markets outside the United States, we generally plan to commercialize our product candidates through
collaborative arrangements with leading pharmaceutical and biotechnology companies.

Review
and Approval of Drugs in the United States
In
the United States, FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and implementing regulations.
The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign
statutes and regulations requires the expenditure of substantial time and financial resources. Failure to comply with the applicable
U.S. requirements at any time during the product development process, approval process or after approval may subject an applicant
and/or sponsor to a variety of administrative or judicial sanctions, including refusal by FDA to approve pending applications,
withdrawal of an approval, imposition of a clinical hold, issuance of warning letters and other types of letters, product recalls,
product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts,
restitution, disgorgement of profits, or civil or criminal investigations and penalties brought by FDA and the Department of Justice,
or DOJ, or other governmental entities.
Our
product candidates must be approved by FDA through the new drug application, or NDA, or biologics license application, or BLA,
in the case of biologic product candidates, process before they may be legally marketed in the United States. An applicant seeking
approval to market and distribute a new drug product in the United States must typically undertake the following:
●
completion
of nonclinical laboratory tests, animal studies and formulation studies in compliance with FDA’s good laboratory practice,
or cGLP, regulations;
●
submission
to FDA of an IND, which must take effect before human clinical trials may begin;
●
approval
by an independent institutional review board, or IRB, representing each clinical site before each clinical trial may be initiated;
●
performance
of adequate and well-controlled human clinical trials in accordance with current good clinical practices, or GCP, to establish
the safety and efficacy of the proposed drug product for each indication;
●
preparation
and submission to FDA of an NDA or BLA;
●
review
of the product by an FDA advisory committee, where appropriate or if applicable;
●
satisfactory
completion of one or more FDA inspections of the manufacturing facility or facilities at which the product, or components
thereof, are produced to assess compliance with current Good Manufacturing Practices, or cGMP, requirements and to assure
that the facilities, methods and controls are adequate to preserve the product’s identity, strength, quality and purity;
●
payment
of user fees and securing FDA approval of the NDA or BLA; and
●
compliance
with any post-approval requirements, including a risk evaluation and mitigation strategy, or REMS, and post-approval studies
required by FDA.
Nonclinical
Studies
Nonclinical
studies include laboratory evaluation of the purity and stability of the manufactured drug substance or active pharmaceutical
ingredient and the formulated drug or drug product, as well as in vitro and animal studies to assess the safety and activity
of the drug for initial testing in humans and to establish a rationale for therapeutic use. The conduct of nonclinical studies
is subject to federal regulations and requirements, including cGLP regulations. The results of the nonclinical tests, together
with manufacturing information, analytical data, any available clinical data or literature and plans for clinical trials, among
other things, are submitted to FDA as part of an investigational new drug application, or IND.
27
Companies
usually must complete some long-term nonclinical testing, such as animal tests of reproductive adverse events and carcinogenicity,
and must also develop additional information about the chemistry and physical characteristics of the drug and finalize a process
for manufacturing the drug in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable
of consistently producing quality batches of the drug candidate and, among other things, the manufacturer must develop methods
for testing the identity, strength, quality and purity of the final drug product. Additionally, appropriate packaging must be
selected and tested and stability studies must be conducted to demonstrate that the drug candidate does not undergo unacceptable
deterioration over its shelf life.
Human
Clinical Trials in Support of a Regulatory Approval
Clinical
trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators
in accordance with GCP requirements, which include, among other things, the requirement that all research subjects provide their
informed consent in writing before their participation in any clinical trial. Clinical trials are conducted under written study
protocols detailing, among other things, the objectives of the study, the parameters to be used in monitoring safety and the effectiveness
criteria to be evaluated. A protocol for each clinical trial and any subsequent protocol amendments must be submitted to FDA as
part of the IND. An IND automatically becomes effective 30 days after receipt by FDA, unless before that time FDA raises concerns
or questions related to a proposed clinical trial and places the trial on clinical hold. In such a case, the IND sponsor and FDA
must resolve any outstanding concerns before the clinical trial can begin. Accordingly, submission of an IND may or may not result
in FDA allowing clinical trials to commence.
In
addition, an IRB representing each institution participating in the clinical trial must review and approve the plan for any clinical
trial before it commences at that institution, and the IRB must conduct continuing review and reapprove the study at least annually.
The IRB must review and approve, among other things, the study protocol and informed consent information to be provided to study
subjects. An IRB must operate in compliance with FDA regulations. Information about certain clinical trials must be submitted
within specific timeframes to the National Institutes of Health for public dissemination on their ClinicalTrials.gov website.
A
sponsor who wishes to conduct a clinical trial outside the United States may, but need not, obtain FDA authorization to conduct
the clinical trial under an IND. When a foreign clinical study is conducted under an IND, all FDA IND requirements must be met
unless waived. If a foreign clinical trial is not conducted under an IND, the sponsor may submit data from the clinical trial
to FDA in support of an NDA or IND so long as the clinical trial is conducted in accordance with GCP and if FDA is able to validate
the data from the clinical trial through an on-site inspection, if FDA deems it necessary.
Human
clinical trials are typically conducted in three sequential phases, which may overlap or be combined:
Phase
1 : The drug is initially introduced into a small number of healthy human subjects or patients with the target disease (e.g.
cancer) or condition and tested for safety, dosage tolerance, absorption, metabolism, distribution, excretion and, if possible,
to gain an early indication of its effectiveness and to determine optimal dosage.
Phase
2 : The drug is administered to a larger number of trial participants, up to several hundred, who usually have the disease
or condition that the experimental drug is intended to treat, to identify possible adverse effects and safety risks, to preliminarily
evaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage.
Phase
3 : These clinical trials are commonly referred to as “pivotal” studies, which typically denotes a study which
presents the data that FDA or other relevant regulatory agency will use to determine whether or not to approve a drug. In Phase
3 clinical trials, the drug is administered to an expanded patient population, generally at geographically dispersed clinical
trial sites, in well-controlled clinical trials to generate enough data to statistically evaluate the efficacy and safety of the
product for approval, to establish the overall risk-benefit profile of the product, and to provide adequate information for the
labeling of the product.
28
Progress
reports detailing the results of the clinical trials must be submitted at least annually to FDA and more frequently if serious
adverse events occur. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period,
or at all. Furthermore, FDA or the sponsor may suspend or terminate a clinical trial at any time on various grounds, including
a finding that the research subjects are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate
approval of a clinical trial at its institution, or an institution it represents, if the clinical trial is not being conducted
in accordance with the IRB’s requirements or if the drug has been associated with unexpected serious harm to patients. FDA
will typically inspect one or more clinical sites to assure compliance with GCP and the integrity of the clinical data submitted.
Submission
of an NDA to FDA
Regulatory
approval for most new drug or biologic products is based on two adequate and well-controlled Phase 3 clinical trials that provide
evidence of the safety and efficacy of the proposed new product. Assuming successful completion of required clinical testing and
other requirements, the results of the nonclinical and clinical trials, together with detailed information relating to the product’s
chemistry, manufacture, controls and proposed labeling, among other things, are submitted to FDA as part of an NDA requesting
approval to market the drug product for one or more indications. Under federal law, the submission of most NDAs is additionally
subject to an application user fee and the sponsor of an approved NDA is also subject to annual prescription drug program fees
and establishment user fees. These fees are typically increased annually.
FDA
conducts a preliminary review of an NDA within 60 days of its receipt and informs the sponsor by the 74th day after FDA’s
receipt of the submission whether the application is sufficiently complete to permit substantive review. FDA may request additional
information rather than accept an NDA for filing. In this event, the application must be resubmitted with the additional information.
The resubmitted application is also subject to review before FDA accepts it for filing. Once the submission is accepted for filing,
FDA begins an in-depth substantive review. FDA has agreed to specified performance goals in the review process of NDAs. Most such
applications are meant to be reviewed within ten months from the date of filing, and most applications for “priority review”
products are meant to be reviewed within six months of filing. The review process may be extended by FDA for various reasons,
and for various time periods, including for three additional months to consider new information or clarification provided by the
applicant to address an outstanding deficiency identified by FDA following the original submission.
Before
approving an NDA, FDA typically will inspect the facility or facilities where the product is or will be manufactured. These pre-approval
inspections cover all facilities associated with an NDA submission, including drug component manufacturing (such as Active Pharmaceutical
Ingredients), finished drug product manufacturing and control testing laboratories. FDA will not approve an application unless
it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure
consistent production of the product within required specifications. Additionally, before approving an NDA, FDA will typically
inspect one or more clinical sites to assure compliance with GCP.
FDA
is required to refer an application for a novel drug to an advisory committee or explain why such referral was not made. Typically,
an advisory committee is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates
and provides a recommendation as to whether the application should be approved and under what conditions. FDA is not bound by
the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.
Fast
Track, Breakthrough Therapy and Priority Review Designations
FDA
is authorized to designate certain products for expedited review if they are intended to address an unmet medical need in the
treatment of a serious or life-threatening disease or condition. These programs are fast track designation, breakthrough therapy
designation and priority review designation.
Specifically,
FDA may designate a product for Fast Track review if it is intended, whether alone or in combination with one or more other drugs,
for the treatment of a serious or life-threatening disease or condition, and it demonstrates the potential to address unmet medical
needs for such a disease or condition. For Fast Track products, sponsors may have greater interactions with FDA and FDA may initiate
review of sections of a fast track product’s NDA before the application is complete. This rolling review may be available
if FDA determines, after preliminary evaluation of clinical data submitted by the sponsor, that a Fast Track product may be effective.
The sponsor must also provide, and FDA must approve, a schedule for the submission of the remaining information and the sponsor
must pay applicable user fees. However, FDA’s time period goal for reviewing a Fast Track application does not begin until
the last section of the NDA is submitted. In addition, the Fast Track designation may be withdrawn by FDA if FDA believes that
the designation is no longer supported by data emerging in the clinical trial process.
29
Second,
in 2012, Congress enacted the Food and Drug Administration Safety and Improvement Act, or FDASIA. This law established a new regulatory
scheme allowing for expedited review of products designated as “breakthrough therapies.” A product may be designated
as a breakthrough therapy if it is intended, either alone or in combination with one or more other drugs, to treat a serious or
life-threatening disease or condition and preliminary clinical evidence indicates that the product may demonstrate substantial
improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed
early in clinical development. FDA may take certain actions with respect to breakthrough therapies, including holding meetings
with the sponsor throughout the development process; providing timely advice to the product sponsor regarding development and
approval; involving more senior staff in the review process; assigning a cross-disciplinary project lead for the review team;
and taking other steps to design the clinical trials in an efficient manner.
Third,
FDA may designate a product for priority review if it is a drug that treats a serious condition and, if approved, would provide
a significant improvement in safety or effectiveness. FDA determines, on a case-by-case basis, whether the proposed drug represents
a significant improvement when compared with other available therapies. Significant improvement may be illustrated by evidence
of increased effectiveness in the treatment of a condition, elimination or substantial reduction of a treatment-limiting drug
reaction, documented enhancement of patient compliance that may lead to improvement in serious outcomes, and evidence of safety
and effectiveness in a new subpopulation. A priority designation is intended to direct overall attention and resources to the
evaluation of such applications, and to shorten FDA’s goal for taking action on a marketing application from ten months
to six months.
Under
Section 524 of the FDCA, FDA is authorized to award a priority review voucher to sponsors of certain tropical disease product
applications that meet the criteria specified in the Act. A priority review voucher may be used by the sponsor who obtains it,
or it may be transferred to another sponsor who may use it to obtain priority review for a different application. Priority review
vouchers can result in the acceleration of review and approval of a product candidate by up to four months. In order to be eligible
for a tropical disease priority review voucher, the application must be: for a listed tropical disease; submitted under Section
505(b)(1) of the FDCA or Section 351 of the Public Health Service Act; for a product that contains no active ingredient that has
been approved in any other application under those statutory provisions; and must qualify for priority review. FDA has identified
in guidance those product applications for the prevention or treatment of tropical diseases that may qualify for a priority review
voucher.
Accelerated
Approval Pathway
FDA
may grant accelerated approval to a drug for a serious or life-threatening condition that provides meaningful therapeutic advantage
to patients over existing treatments based upon a determination that the drug has an effect on a surrogate endpoint that is reasonably
likely to predict clinical benefit. FDA may also grant accelerated approval for such a condition when the product has an effect
on an intermediate clinical endpoint that can be measured earlier than an effect on irreversible morbidity or mortality, or IMM,
and that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into
account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. Drugs granted
accelerated approval must meet the same statutory standards for safety and effectiveness as those granted traditional approval.
For
the purposes of accelerated approval, a surrogate endpoint is a marker, such as a laboratory measurement, radiographic image,
physical sign, or other measure that is thought to predict clinical benefit but is not itself a measure of clinical benefit. Surrogate
endpoints can often be measured more easily or more rapidly than clinical endpoints. An intermediate clinical endpoint is a measurement
of a therapeutic effect that is considered reasonably likely to predict the clinical benefit of a drug, such as an effect on IMM.
FDA has limited experience with accelerated approvals based on intermediate clinical endpoints but has indicated that such endpoints
generally may support accelerated approval where the therapeutic effect measured by the endpoint is not itself a clinical benefit
and basis for traditional approval, if there is a basis for concluding that the therapeutic effect is reasonably likely to predict
the ultimate clinical benefit of a drug.
30
The
accelerated approval pathway is most often used in settings in which the course of a disease is long, and an extended period of
time is required to measure the intended clinical benefit of a drug, even if the effect on the surrogate or intermediate clinical
endpoint occurs rapidly. The accelerated approval pathway is usually contingent on a sponsor’s agreement to conduct, in
a diligent manner, additional post-approval confirmatory studies to verify and describe the drug’s clinical benefit. As
a result, a product candidate approved on this basis is subject to rigorous post-marketing compliance requirements, including
the completion of Phase 4 or post-approval clinical trials to confirm the effect on the clinical endpoint. Failure to conduct
required post-approval studies, or confirm a clinical benefit during post-marketing studies, would allow FDA to withdraw the drug
from the market on an expedited basis. All promotional materials for product candidates approved under accelerated regulations
are subject to prior review by FDA.
FDA’s
Decision on an NDA
On
the basis of FDA’s evaluation of the NDA and accompanying information, including the results of the inspection of the manufacturing
facilities, FDA may issue an approval letter or a complete response letter. An approval letter authorizes commercial marketing
of the product with specific prescribing information for specific indications. A complete response letter generally outlines the
deficiencies in the submission and may require substantial additional testing or information in order for FDA to reconsider the
application. If and when those deficiencies have been addressed to FDA’s satisfaction in a resubmission of the NDA, FDA
will issue an approval letter. FDA has committed to reviewing such resubmissions in two or six months depending on the type of
information included. Even with submission of this additional information, FDA ultimately may decide that the application does
not satisfy the regulatory criteria for approval.
If
FDA approves a product, it may limit the approved indications for use for the product, require that contraindications, warnings
or precautions be included in the product labeling, require that post-approval studies, including Phase 4 clinical trials, be
conducted to further assess the drug’s safety after approval, require testing and surveillance programs to monitor the product
after commercialization, or impose other conditions which can materially affect the potential market and profitability of the
product. In addition, as a condition of approval, FDA may require an applicant to develop a REMS. REMS use risk minimization strategies
beyond the professional labeling to ensure that the benefits of the product outweigh the potential risks. To determine whether
a REMS is needed, FDA will consider the size of the population likely to use the product, seriousness of the disease, expected
benefit of the product, expected duration of treatment, seriousness of known or potential adverse events and whether the product
is a new molecular entity. REMS can include medication guides, physician communication plans for healthcare professionals and
elements to assure safe use, which may include, but are not limited to, special training or certification for prescribing or dispensing,
dispensing only under certain circumstances, special monitoring and the use of patient registries. FDA may require a REMS before
approval or post-approval if it becomes aware of a serious risk associated with use of the product. The requirement for a REMS
can materially affect the potential market and profitability of a product.
FDA
may prevent or limit further marketing of a product based on the results of post-market studies or surveillance programs. After
approval, many types of changes to the approved product, such as adding new indications, manufacturing changes and additional
labeling claims, are subject to further testing requirements and FDA review and approval.
Post-Approval
Requirements
Drugs
manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by FDA, including, among
other things, requirements relating to recordkeeping, periodic reporting, product sampling and distribution, advertising and promotion
and reporting of adverse experiences with the product. After approval, most changes to the approved product, such as adding new
indications or other labeling claims, are subject to prior FDA review and approval. There also are continuing, annual user fee
requirements for any marketed products and the establishments at which such products are manufactured, as well as new application
fees for supplemental applications with clinical data.
In
addition, drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to
register their establishments with FDA and state agencies and are subject to periodic unannounced inspections by FDA and these
state agencies for compliance with cGMP requirements. Changes to the manufacturing process are strictly regulated and often require
prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from
cGMP and impose reporting and documentation requirements upon the sponsor and any third-party manufacturers that the sponsor may
decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality
control to maintain cGMP compliance.
31
Once
an approval is granted, FDA may withdraw the approval if compliance with regulatory requirements and standards is not maintained
or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including
adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements,
may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical
trials to assess new safety risks; or imposition of distribution or other restrictions under a REMS program. Other potential consequences
include, among other things:
●
restrictions
on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;
●
fines,
warning or untitled letters or holds on post-approval clinical trials;
●
refusal
of FDA to approve pending NDAs or supplements to approved NDAs, or suspension or revocation of product approvals;
●
product
seizure or detention, or refusal to permit the import or export of products; or
●
injunctions
or the imposition of civil or criminal penalties.
FDA
strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Drugs may be promoted
only for the approved indications and in accordance with the provisions of the approved label. FDA and other agencies actively
enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted
off-label uses may be subject to significant liability.
In
addition, the distribution of prescription pharmaceutical products is subject to the Prescription Drug Marketing Act, or PDMA,
which regulates the distribution of drugs and drug samples at the federal level and sets minimum standards for the registration
and regulation of drug distributors by the states. Both the PDMA and state laws limit the distribution of prescription pharmaceutical
product samples and impose requirements to ensure accountability in distribution.
Abbreviated
New Drug Applications for Generic Drugs
In
1984, with passage of the Hatch-Waxman Amendments to the FDCA, Congress authorized FDA to approve generic drugs that are the same
as drugs previously approved by FDA under the NDA provisions of the statute. To obtain approval of a generic drug, an applicant
must submit an abbreviated new drug application, or ANDA, to the agency. In support of such applications, a generic manufacturer
may rely on the nonclinical and clinical testing previously conducted for a drug product previously approved under an NDA, known
as the reference listed drug, or RLD.
Specifically,
in order for an abbreviated new drug application, or ANDA to be approved, FDA must find that the generic version is identical
to the RLD with respect to the active ingredients, the route of administration, the dosage form and the strength of the drug.
At the same time, FDA must also determine that the generic drug is “bioequivalent” to the innovator drug. Under the
statute, a generic drug is bioequivalent to a RLD if the rate and extent of absorption of the drug do not show a significant difference
from the rate and extent of absorption of the listed drug.
Upon
approval of an ANDA, FDA indicates whether the generic product is therapeutically equivalent to the RLD in its publication “Approved
Drug Products with Therapeutic Equivalence Evaluations,” also referred to as the “Orange Book.” Physicians and
pharmacists consider a therapeutically equivalent generic drug to be fully substitutable for the RLD. In addition, by operation
of certain state laws and numerous health insurance programs, FDA’s designation of therapeutic equivalence often results
in automatic substitution of the generic drug by the pharmacist without the knowledge or consent of either the prescribing physician
or patient.
32
Under
the Hatch-Waxman Amendments, FDA may not approve an ANDA until any applicable period of non-patent exclusivity for the RLD has
expired. The FDCA provides a period of five years of non-patent data exclusivity for a new drug containing a new chemical entity.
In cases where such exclusivity has been granted, an ANDA may not be submitted to FDA until the expiration of five years unless
the submission is accompanied by a Paragraph IV certification, in which case the applicant may submit its application four years
following the original product approval. The FDCA also provides for a period of three years of exclusivity if the NDA includes
reports of one or more new clinical investigations, other than bioavailability or bioequivalence studies, that were conducted
by or for the applicant and are essential to the approval of the application. This three-year exclusivity period often protects
changes to a previously approved drug product, such as a new dosage form, route of administration, combination or indication.
Hatch-Waxman
Patent Certification and the 30 Month Stay
Upon
approval of an NDA or a supplement thereto, NDA sponsors are required to list with FDA each patent with claims that cover the
applicant’s product or an approved method of using the product. Each of the patents listed by the NDA sponsor is published
in the Orange Book. When an ANDA applicant submits its application to FDA, the applicant is required to certify to FDA concerning
any patents listed for the reference product in the Orange Book, except for patents covering methods of use for which the ANDA
applicant is not seeking approval. Specifically, the applicant must certify with respect to each patent that:
●
the
required patent information has not been filed;
●
the
listed patent has expired;
●
the
listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or
●
the
listed patent is invalid, unenforceable or will not be infringed by the new product.
A
certification that the new product will not infringe the already approved product’s listed patents or that such patents
are invalid or unenforceable is called a Paragraph IV certification. If the applicant does not challenge the listed patents or
indicate that it is not seeking approval of a patented method of use, the ANDA application will not be approved until all the
listed patents claiming the referenced product have expired.
If
the ANDA applicant has provided a Paragraph IV certification to FDA, the applicant must also send notice of the Paragraph IV certification
to the NDA and patent holders once the ANDA has been accepted for filing by FDA. The NDA and patent holders may then initiate
a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The filing of a patent infringement
lawsuit within 45 days after the receipt of a Paragraph IV certification automatically prevents FDA from approving the ANDA until
the earlier of 30 months after the receipt of the Paragraph IV notice, expiration of the patent, or a decision in the infringement
case that is favorable to the ANDA applicant.
Pediatric
Studies and Exclusivity
Under
the Pediatric Research Equity Act of 2003, an NDA or supplement thereto must contain data that are adequate to assess the safety
and effectiveness of the drug product for the claimed indications in all relevant pediatric subpopulations, and to support dosing
and administration for each pediatric subpopulation for which the product is safe and effective. With enactment of the Food and
Drug Administration Safety and Innovation Act, or FDASIA, in 2012, sponsors must also submit pediatric study plans prior to the
assessment data. Those plans must contain an outline of the proposed pediatric study or studies the applicant plans to conduct,
including study objectives and design, any deferral or waiver requests, and other information required by regulation. The applicant,
FDA and FDA’s internal review committee must then review the information submitted, consult with each other, and agree upon
a final plan. FDA or the applicant may request an amendment to the plan at any time.
FDA
may, on its own initiative or at the request of the applicant, grant deferrals for submission of some or all pediatric data until
after approval of the product for use in adults, or full or partial waivers from the pediatric data requirements. Additional requirements
and procedures relating to deferral requests and requests for extension of deferrals are contained in FDASIA.
33
Pediatric
exclusivity is another type of non-patent marketing exclusivity in the United States and, if granted, provides for the attachment
of an additional six months of marketing protection to the term of any existing regulatory exclusivity, including the non-patent
exclusivity. This six-month exclusivity may be granted if an NDA sponsor submits pediatric data that fairly respond to a written
request from FDA for such data. The data do not need to show the product to be effective in the pediatric population studied;
rather, if the clinical trial is deemed to fairly respond to FDA’s request, the additional protection is granted. If reports
of requested pediatric studies are submitted to and accepted by FDA within the statutory time limits, whatever statutory or regulatory
periods of exclusivity or patent protection cover the product are extended by six months. This is not a patent term extension,
but it effectively extends the regulatory period during which FDA cannot approve another application.
Orphan
Designation and Exclusivity
Under
the Orphan Drug Act, FDA may designate a drug product as an “orphan drug” if it is intended to treat a rare disease
or condition (generally meaning that it affects fewer than 200,000 individuals in the United States, or more in cases in which
there is no reasonable expectation that the cost of developing and making a drug product available in the United States for treatment
of the disease or condition will be recovered from sales of the product). A company must request orphan product designation before
submitting a NDA. If the request is granted, FDA will disclose the identity of the therapeutic agent and its potential use. Orphan
product designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.
If
a product with orphan status receives the first FDA approval for the disease or condition for which it has such designation, the
product will be entitled to orphan product exclusivity. Orphan product exclusivity means that FDA may not approve any other applications
for the same product for the same indication for seven years, except in certain limited circumstances. Competitors may receive
approval of different products for the indication for which the orphan product has exclusivity and may obtain approval for the
same product but for a different indication. If a drug or drug product designated as an orphan product ultimately receives marketing
approval for an indication broader than what was designated in its orphan product application, it may not be entitled to exclusivity.
21st
Century Cures Act
On
December 13, 2016, Congress passed the 21 st Century Cures Act, or the Cures Act. The Cures Act is designed to modernize
and personalize healthcare, spur innovation and research, and streamline the discovery and development of new therapies through
increased federal funding of particular programs. It authorizes increased funding for FDA to spend on innovation projects. The
new law also amends the Public Health Service Act to reauthorize and expand funding for the National Institutes of Health. The
Act establishes the NIH Innovation Fund to pay for the cost of development and implementation of a strategic plan, early-stage
investigators and research. It also charges NIH with leading and coordinating expanded pediatric research. In addition, the Cures
Act includes provisions requiring FDA to assess and publish guidance on the use of novel clinical trial designs, the use of real-world
evidence in applications, the availability of summary level review for supplemental applications for certain indications, and
the qualification of drug development tools. Because the Cures Act has only recently been enacted, its potential effect on our
business remains unclear with the exception of a provision requiring that we post our policies on the availability of expanded
access programs for individuals. Because these provisions allow FDA to spend several years developing these policies, the effect
on us could be delayed.
With
amendments to the FDCA and the Public Health Service Act, or PHSA, Title III of the Cures Act seeks to accelerate the discovery,
development, and delivery of new medicines and medical technologies. To that end, and among other provisions, the Cures Act reauthorizes
the existing priority review voucher program for certain drugs intended to treat rare pediatric diseases until 2020; creates a
new priority review voucher program for drug applications determined to be material national security threat medical countermeasure
applications; and revises the FDCA to streamline review of combination product applications.
34
Section
3042 of the Cures Act authorizes a new “Limited Population Pathway” to expedite approval of antimicrobial products
intended to treat serious or life-threatening infections for which there are unmet medical needs. Drugs approved under this provision
would be required to adhere to special labeling requirements, including a prominent “Limited Population” statement.
Additionally, in recognition of increasing concerns about drug-resistant infections, the Act requires the U.S. Government Accountability
Office (GAO) to compile a report on antimicrobial resistance by 2021, which would include a review of any effect of the new Limited
Population Pathway on antibacterial or antifungal resistance. We will monitor these developments but cannot currently assess how
this initiative may impact our business.
Other
Health Care Regulations
Health
Privacy Laws
We
are subject to data protection laws and regulations (i.e., laws and regulations that address privacy and data security). In the
U.S., numerous federal and state laws and regulations, including state data breach notification laws, state health information
privacy laws, and federal and state consumer protection laws (e.g., Section 5 of the FTC Act), govern the collection, use, disclosure,
and protection of health-related and other personal information. Failure to comply with data protection laws and regulations could
result in government enforcement actions and create liability for us (which could include civil and/or criminal penalties), private
litigation and/or adverse publicity that could negatively affect our operating results and business. In addition, we may obtain
health information from third parties (e.g., principal investigators involved in our clinical trials) that are subject to privacy
and security requirements under the Health Insurance Portability and Accountability Act of 1996, or HIPPA, as amended by the Health
Information Technology for Economic and Clinical Health Act, or HITECH. HIPAA generally requires that covered entities (healthcare
providers, health plans and healthcare clearinghouses) obtain written authorizations from patients prior to disclosing protected
health information of the patient (unless an exception to the authorization requirement applies). If authorization is required
and the patient fails to execute an authorization or the authorization fails to contain all required provisions, then we may not
be allowed access to and use of the patient’s information and our research efforts could be impaired or delayed. Furthermore,
use of protected health information that is provided to us pursuant to a valid patient authorization is subject to the limits
set forth in the authorization (e.g., for use in research and in submissions to regulatory authorities for product approvals).
Among other things, HITECH makes HIPAA’s privacy and security standards, as well as the various penalties or failure to
comply, directly applicable to “business associates”—independent contractors or agents of covered entities performing
certain functions involving the creation or use of protected health information on behalf of a covered entity or providing services
to a covered entity. While we do not believe we are a “business associate” under HIPAA, regulatory agencies may disagree.
The
collection and use of personal health data in the European Union, presently governed by the provisions of the European Data Protection
Directive (95/46/EC), or the EU Directive, as implemented by the European Member States, will be replaced with the General Data
Protection Regulation, or GDPR. Currently, the EU Directive establishes a regulatory framework designed to protect the security
of personal data collected about residents of the EU and the movement of such personal data across the national borders of the
EU Member States. The EU Directive would apply to clinical trial data we may collect about residents of the European Union. GDPR
was adopted in 2016 and will become enforceable in the European Union Member States in May 2018. The GDPR will impose many new
or additional requirements including, but not limited to, obtaining consent of the individuals to whom the personal data relates,
the nature and scope of notifications provided to the individuals, the security and confidentiality of the personal data, data
breach notification and using third party processors in connection with the processing of the personal data. Failure to comply

Fraud
and Abuse Laws
In
addition to FDA restrictions on marketing of pharmaceutical products, several other types of state and federal laws have been
applied to restrict certain marketing practices in the pharmaceutical industry in recent years. These laws include anti-kickback
statutes and false claims statutes. The federal healthcare program anti-kickback statute prohibits, among other things, knowingly
and willfully offering, paying, soliciting or receiving remuneration to induce or in return for purchasing, leasing, ordering
or arranging for the purchase, lease or order of any healthcare item or service reimbursable under Medicare, Medicaid or other
federally financed healthcare programs. This statute has been interpreted to apply to arrangements between pharmaceutical manufacturers
on the one hand and prescribers, purchasers and formulary managers on the other. Violations of the anti-kickback statute are punishable
by imprisonment, criminal prosecution, civil monetary penalties and exclusion from participation in federal healthcare programs.
Although there are a number of statutory exemptions and regulatory safe harbors protecting certain common activities from prosecution
or other regulatory sanctions, the exemptions and safe harbors are drawn narrowly, and practices that involve remuneration intended
to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exemption or safe
harbor.
35
Federal
false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the
federal government, or knowingly making, or causing to be made, a false statement to have a false claim paid. Recently, several
pharmaceutical and other healthcare companies have been prosecuted under these laws for allegedly inflating drug prices they report
to pricing services, which in turn were used by the government to set Medicare and Medicaid reimbursement rates, and for allegedly
providing free product to customers with the expectation that the customers would bill federal programs for the product. In addition,
certain marketing practices, including off-label promotion, may also violate false claims laws. The majority of states also have
statutes or regulations similar to the federal anti-kickback statute and false claims laws, which apply to items and services
reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payor.
Affordable
Care Act
In
late March 2010, the Federal government enacted the comprehensive health care reform package, the Affordable Care Act (ACA). Among
other provisions, the ACA imposes individual and employer health insurance requirements, provides certain insurance subsidies
(e.g., premiums and cost sharing), mandates extensive insurance market reforms, creates new health insurance access points (e.g.,
State and federal-based health insurance exchanges), expands the Medicaid program, promotes research on comparative clinical effectiveness
of different technologies and procedures, and makes a number of changes to how products and services will be reimbursed by the
Medicare program. Amendments to the Federal False Claims Act under the ACA have made it easier for private parties to bring “qui
tam” (whistleblower) lawsuits against companies, under which the whistleblower may be entitled to receive a percentage of
any money paid to the government.
Since
its enactment, there have been judicial and Congressional challenges and amendments to certain aspects of the ACA. There is continued
uncertainty about the implementation of the ACA, including the potential for further amendments to the ACA and legal challenges
to or efforts to repeal the ACA. If the ACA is repealed or further modified, or if implementation of certain aspects of the ACA
are delayed, such repeal, modification or delay may materially adversely impact our business, strategies, prospects, operating
results or financial condition. We are unable to predict the full impact of any repeal, modification or delay in the implementation
of the ACA on us at this time. Due to the substantial regulatory changes that will need to be implemented by CMS and others, and
the numerous processes required to implement these reforms, we cannot predict which healthcare initiatives will be implemented
at the federal or state level, the timing of any such reforms, or the effect such reforms or any other future legislation or regulation
will have on our business.
Designation
of and Exclusivity for Qualified Infectious Disease Products
In
2012, Congress passed legislation known as the Generating Antibiotic Incentives Now Act, or GAIN Act. This legislation is designed
to encourage the development of antibacterial and antifungal drug products that treat pathogens that cause serious and life-threatening
infections. To that end, the law grants an additional five years of marketing exclusivity upon the approval of an NDA for a drug
product designated by FDA as a Qualified Infectious Disease Product, or QIDP. Thus, for a QIDP, the periods of five-year new chemical
entity exclusivity, three year new clinical investigation exclusivity and seven year orphan drug exclusivity, would become 10
years, eight years, and 12 years, respectively.
A
QIDP is defined in the GAIN Act to mean “an antibacterial or antifungal drug for human use intended to treat serious or
life-threatening infections, including those caused by—(1) an antibacterial or antifungal resistant pathogen, including
novel or emerging infectious pathogens;” or (2) certain “qualifying pathogens.” A “qualifying pathogen”
is a pathogen that has the potential to pose a serious threat to public health (e.g., resistant gram-positive pathogens, multi-drug
resistant gram negative bacteria, multi-drug resistant tuberculosis and Clostridium difficile ) and that is included in
a list established and maintained by FDA. A drug sponsor may request FDA to designate its product as a QIDP any time before the
submission of an NDA. FDA must make a QIDP determination within 60 days of the designation request. A product designated as a
QIDP will be granted priority review by FDA and can qualify for “fast track” status.
36
The
additional five years of market exclusivity under the GAIN Act for drug products designated by FDA as QIDPs applies only to a
drug that is first approved on or after July 9, 2012. Additionally, the five-year exclusivity extension does not apply to: a supplement
to an application under Section 505(b) of the FDCA for any QIDP for which an extension is in effect or has expired; a subsequent
application submitted with respect to a product approved by FDA for a change that results in a new indication, route of administration,
dosing schedule, dosage form, delivery system, delivery device or strength; or a product that does not meet the definition of
a QIDP under Section 505(g) based upon its approved uses.
Patent
Term Restoration and Extension
A
patent claiming a new drug product may be eligible for a limited patent term extension under the Hatch-Waxman Act, which permits
a patent restoration of up to five years for patent term lost during product development and FDA regulatory review. The restoration
period granted is typically one-half the time between the effective date of an IND and the submission date of a NDA, plus the
time between the submission date of a NDA and the ultimate approval date. Patent term restoration cannot be used to extend the
remaining term of a patent past a total of 14 years from the product’s approval date. Only one patent applicable to an approved
drug product is eligible for the extension, and the application for the extension must be submitted prior to the expiration of
the patent in question. A patent that covers multiple drugs for which approval is sought can only be extended in connection with
one of the approvals. The USPTO reviews and approves the application for any patent term extension or restoration in consultation
with FDA.
Review
and Approval of Drug Products in the European Union
In
order to market any product outside of the United States, a company must also comply with numerous and varying regulatory requirements
of other countries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials,
marketing authorization, commercial sales and distribution of drug products. Whether or not it obtains FDA approval for a product,
the company would need to obtain the necessary approvals by the comparable non-U.S. regulatory authorities before it can commence
clinical trials or marketing of the product in those countries or jurisdictions. The approval process ultimately varies between
countries and jurisdictions and can involve additional product testing and additional administrative review periods. The time
required to obtain approval in other countries and jurisdictions might differ from and be longer than that required to obtain
FDA approval. Regulatory approval in one country or jurisdiction does not ensure regulatory approval in another, but a failure
or delay in obtaining regulatory approval in one country or jurisdiction may negatively impact the regulatory process in others.
Pursuant
to the European Clinical Trials Directive, a system for the approval of clinical trials in the European Union has been implemented
through national legislation of the member states. Under this system, an applicant must obtain approval from the competent national
authority of a European Union member state in which the clinical trial is to be conducted. Furthermore, the applicant may only
start a clinical trial after a competent ethics committee has issued a favorable opinion. Clinical trial application must be accompanied
by an investigational medicinal product dossier with supporting information prescribed by the European Clinical Trials Directive
and corresponding national laws of the member states and further detailed in applicable guidance documents.
To
obtain marketing approval of a drug under European Union regulatory systems, an applicant must submit a marketing authorization
application, or MAA, either under a centralized or decentralized procedure.
The
centralized procedure provides for the grant of a single marketing authorization by the European Commission that is valid for
all European Union member states. The centralized procedure is compulsory for specific products, including for medicines produced
by certain biotechnological processes, products designated as orphan medicinal products, advanced therapy products and products
with a new active substance indicated for the treatment of certain diseases. For products with a new active substance indicated
for the treatment of other diseases and products that are highly innovative or for which a centralized process is in the interest
of patients, the centralized procedure may be optional.
37
Under
the centralized procedure, the Committee for Medicinal Products for Human Use, or the CHMP, established at the European Medicines
Agency, or EMA, is responsible for conducting the initial assessment of a drug. The CHMP is also responsible for several post-authorization
and maintenance activities, such as the assessment of modifications or extensions to an existing marketing authorization. Under
the centralized procedure in the European Union, the maximum timeframe for the evaluation of an MAA is 210 days, excluding clock
stops, when additional information or written or oral explanation is to be provided by the applicant in response to questions
of the CHMP. Accelerated evaluation might be granted by the CHMP in exceptional cases, when a medicinal product is of major interest
from the point of view of public health and in particular from the viewpoint of therapeutic innovation. In this circumstance,
the EMA ensures that the opinion of the CHMP is given within 150 days.
The
decentralized procedure is available to applicants who wish to market a product in various European Union member states where
such product has not received marketing approval in any European Union member states before. The decentralized procedure provides
for approval by one or more other, or concerned, member states of an assessment of an application performed by one-member state
designated by the applicant, known as the reference member state. Under this procedure, an applicant submits an application based
on identical dossiers and related materials, including a draft summary of product characteristics, and draft labeling and package
leaflet, to the reference member state and concerned member states. The reference member state prepares a draft assessment report
and drafts of the related materials within 210 days after receipt of a valid application. Within 90 days of receiving the reference
member state’s assessment report and related materials, each concerned member state must decide whether to approve the assessment
report and related materials.
If
a member state cannot approve the assessment report and related materials on the grounds of potential serious risk to public health,
the disputed points are subject to a dispute resolution mechanism and may eventually be referred to the European Commission, whose
decision is binding on all member states.
Pharmaceutical
Coverage, Pricing and Reimbursement
Significant
uncertainty exists as to the coverage and reimbursement status of products approved by FDA and other government authorities. Sales
of products will depend, in part, on the extent to which the costs of the products will be covered by third party payors, including
government health programs in the United States such as Medicare and Medicaid, commercial health insurers and managed care organizations.
The process for determining whether a payor will provide coverage for a product may be separate from the process for setting the
price or reimbursement rate that the payor will pay for the product once coverage is approved. Third party payors may limit coverage
to specific products on an approved list, or formulary, which might not include all of the approved products for a particular
indication. Additionally, the containment of healthcare costs has become a priority of federal and state governments, and the
prices of drugs have been a focus in this effort. The U.S. government, state legislatures and foreign governments have shown significant
interest in implementing cost-containment programs, including price controls, restrictions on reimbursement and requirements for
substitution of generic products. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies
in jurisdictions with existing controls and measures, could further limit our net revenue and results.
In
order to secure coverage and reimbursement for any product that might be approved for sale, a company may need to conduct expensive
pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product, in addition to the
costs required to obtain FDA or other comparable regulatory approvals. A payor’s decision to provide coverage for a product
does not imply that an adequate reimbursement rate will be approved. Third party reimbursement may not be sufficient to maintain
price levels high enough to realize an appropriate return on investment in product development.
In
the European Union, pricing and reimbursement schemes vary widely from country to country. Some countries provide that drug products
may be marketed only after a reimbursement price has been agreed. Some countries may require the completion of additional studies
that compare the cost-effectiveness of a particular product candidate to currently available therapies. For example, the European
Union provides options for its member states to restrict the range of drug products for which their national health insurance
systems provide reimbursement and to control the prices of medicinal products for human use. European Union member states may
approve a specific price for a drug product, or it may instead adopt a system of direct or indirect controls on the profitability
of the company placing the drug product on the market. Other member states allow companies to fix their own prices for drug products
but monitor and control company profits. The downward pressure on health care costs in general, particularly prescription drugs,
has become intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition, in some
countries, cross-border imports from low-priced markets exert competitive pressure that may reduce pricing within a country. Any
country that has price controls or reimbursement limitations for drug products may not allow favorable reimbursement and pricing
arrangements.
38
Healthcare
Law and Regulation
Healthcare
providers, physicians and third-party payors play a primary role in the recommendation and prescription of drug products that
are granted marketing approval. Arrangements with third party payors and customers are subject to broadly applicable fraud and
abuse and other healthcare laws and regulations. Such restrictions under applicable federal and state healthcare laws and regulations,
include the following:
●
the
federal healthcare anti-kickback statute prohibits, among other things, persons from knowingly and willfully soliciting, offering,
receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of
an individual for, or the purchase, order or recommendation of, any good or service, for which payment may be made, in whole
or in part, under a federal healthcare program such as Medicare and Medicaid;
●
the
federal False Claims Act imposes civil penalties, and provides for civil whistleblower or qui tam actions, against individuals
or entities for knowingly presenting, or causing to be presented, to the federal government, claims for payment that are false
or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government;
●
the
HIPPA imposes criminal and civil liability for executing a scheme to defraud any healthcare benefit program or making false
statements relating to healthcare matters;
●
HIPAA,
as amended by the HITECH and its implementing regulations, also imposes obligations, including mandatory contractual terms,
with respect to safeguarding the privacy, security and transmission of individually identifiable health information;
●
the
federal false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or
making any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services;
●
the
federal transparency requirements under the ACA requires manufacturers of drugs to report to the Department of Health and
Human Services information related to payments and other transfers of value to physicians and teaching hospitals and physician
ownership and investment interests and the reported information will be made publicly available on a searchable website; and
●
analogous
state and foreign laws and regulations, such as state anti-kickback and false claims laws, may apply to sales or marketing
arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including
private insurers.
Some
state laws require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines
and the relevant compliance guidance promulgated by the federal government in addition to requiring drug manufacturers to report
information related to payments to physicians and other health care providers or marketing expenditures. State and foreign laws
also govern the privacy and security of health information in some circumstances, many of which differ from each other in significant
ways and often are not preempted by HIPAA, thus complicating compliance efforts.
