Overview and Strategy
Anavex Life Sciences Corp. is a clinical stage
biopharmaceutical company engaged in the development of differentiated therapeutics by applying precision medicine to central nervous
system (“CNS”) diseases with high unmet need. We analyze genomic data from clinical trials to identify biomarkers,
which we use in the analysis of our clinical trials.
Our lead product candidate, ANAVEX ® 2-73,
is being developed to treat Alzheimer’s disease, Parkinson’s disease and potentially other central nervous system diseases,
including rare diseases, such as Rett syndrome, a rare severe neurological monogenic disorder caused by mutations in the X-linked
gene, methyl-CpG-binding protein 2 (“MECP2”).
We currently have two core programs and two
seed programs. Our core programs are at various stages of clinical and preclinical development, in neurodegenerative and neurodevelopmental
diseases.
The following table summarizes key information about our programs:

Anavex has a portfolio of compounds varying
in sigma-1 receptor (SIGMAR1) binding activities. The SIGMAR1 gene encodes the SIGMAR1 protein, which is an intracellular chaperone
protein with important roles in cellular communication. SIGMAR1 is also involved in transcriptional regulation at the nuclear envelope
and restores homeostasis and stimulates recovery of cell function when activated. In order to validate the ability of our compounds
to activate quantitatively the SIGMAR1, we performed, in collaboration with Stanford University, a quantitative Positron Emission
Tomography (PET) imaging scan in mice, which demonstrated a dose-dependent ANAVEX ® 2-73 target engagement or receptor
occupancy with SIGMAR1 in the brain.

Cellular Homeostasis
Many diseases are possibly directly caused
by chronic homeostatic imbalances or cellular stress of brain cells. In pediatric diseases, such as Rett syndrome or infantile
spasms, the chronic cellular stress is possibly caused by the presence of a constant genetic mutation. In neurodegenerative diseases,
such as Alzheimer’s and Parkinson’s diseases, chronic cellular stress is possibly caused by age-correlated buildup
of cellular insult and hence chronic cellular stress. Specifically, defects in homeostasis of protein or ribonucleic acid (“RNA”)
lead to the death of neurons and dysfunction of the nervous system. The spreading of protein aggregates resulting in a proteinopathy,
a characteristic found in Alzheimer’s and Parkinson’s diseases that results from disorders of protein synthesis, trafficking,
folding, processing or degradation in cells. The clearance of macromolecules in the brain is particularly susceptible to imbalances
that result in aggregation and degeneration in nerve cells. For example, Alzheimer’s disease pathology is characterized by
the presence of amyloid plaques, and neurofibrillary tangles, which are aggregates of hyperphosphorylated Tau protein that are
a marker of other diseases known as tauopathies as well as inflammation of microglia. With the SIGMAR1 activation through SIGMAR1
agonists like ANAVEX ® 2-73, our approach is to restore cellular balance (i.e. homeostasis). Therapies that correct
defects in cellular homeostasis might have the potential to halt or delay neurodevelopmental and neurodegenerative disease progression.
ANAVEX ® 2-73-specific Biomarkers
As part of some of our clinical trials, we
have incorporated a genomic analysis to better understand potential populations for whom our clinical programs might benefit. In
our clinical trials, a full genomic analysis of Alzheimer’s disease patients treated with ANAVEX ® 2-73 has
helped us identify actionable genetic variants. A significant impact of the genomic biomarkers SIGMAR1, the direct target of ANAVEX ® 2-73
and COMT, a gene involved in memory function, on the drug response level was identified, leading to an early ANAVEX ® 2-73-specific
biomarker hypothesis. We believe that excluding patients with SIGMAR1 identified biomarker variant (approximately 10%-20%
of the population) in prospective studies would identify approximately 80%-90% patients that would display clinically significant
improved functional and cognitive scores. The consistency between the identified DNA and RNA data related to ANAVEX ® 2-73,
which are considered independent of Alzheimer’s disease pathology, as well as multiple endpoints and time-points, provides
support for the potential precision medicine clinical development of ANAVEX ® 2-73 by using genetic biomarkers identified
within the trial population itself to target patients who are most likely to respond to ANAVEX ® 2-73 treatment. We
may in the future utilize such an approach in Alzheimer’s disease as well as indications like Parkinson’s disease dementia
or Rett syndrome in which ANAVEX ® 2-73 is currently being studied.

Clinical Trials Overview
Alzheimer’s Disease
In November 2016, we completed a Phase 2a clinical
trial, consisting of Part A and Part B, which lasted a total of 57 weeks, for ANAVEX ® 2-73 in mild-to-moderate Alzheimer’s
patients. This open-label, randomized trial in Australia met both primary and secondary endpoints and was designed to assess the
safety and exploratory efficacy of ANAVEX ® 2-73 in 32 patients. ANAVEX ® 2-73 targets sigma-1 and muscarinic
receptors, which have been shown in preclinical studies to reduce stress levels in the brain believed to restore cellular homeostasis
and to reverse the pathological hallmarks observed in Alzheimer’s disease. In October 2017, we presented positive pharmacokinetic
(“PK”) and pharmacodynamic (“PD”) data from the Phase 2a clinical trial, which established a concentration-effect
relationship between ANAVEX ® 2-73 and trial measurements. These measures obtained from all patients who participated
in the entire 57 weeks include exploratory cognitive and functional scores as well as biomarker signals of brain activity. Additionally,
the clinical trial appeared to show that ANAVEX ® 2-73 activity was enhanced by its active metabolite (ANAVEX19-144),
which also targets the SIGMAR1 receptor and has a half-life approximately twice as long as the parent molecule.
Two consecutive trial extensions for the Phase
2a trial have allowed participants who completed the 52-week Part B of the trial to continue taking ANAVEX ® 2-73,
providing us an opportunity to gather extended safety data for a cumulative time period of five years. In August 2020, patients
completing these Phase 2a trial extensions were granted continued access to treatment with ANAVEX ® 2-73 through the
Australian Government Department of Health – Therapeutic Goods Administration’s compassionate use Special Access Scheme.
A larger Phase 2b/3 double-blind, placebo-controlled
trial of ANAVEX ® 2-73 in Alzheimer’s disease commenced in August 2018. The Phase 2b/3 trial enrolled 509 patients
for 48 weeks, randomized 1:1:1 to two different ANAVEX ® 2-73 doses or placebo. The trial commenced in Australia;
and during fiscal 2020 additional regions were added in the United Kingdom, The Netherlands, Germany and Canada. Primary and secondary
endpoints will assess safety and both cognitive and functional efficacy, measured through Alzheimer’s Disease Assessment
Scale – Cognition (ADAS-Cog), ADCS-ADL and Clinical Dementia Rating – Sum of Boxes for cognition and function (CDR-SB).
In addition to the primary endpoints, the ANAVEX ® 2-73 Phase 2b/3 trial design incorporated pre-specified statistical
analyses related to potential genomic precision medicine biomarkers identified in the ANAVEX ® 2-73 Phase 2a clinical
trial. The trial completed enrollment in June 2021, exceeding the 450 patient enrollment target at 52 sites across Canada, Europe
and Australia.
In October 2019, we initiated a long-term
open label extension study of ANAVEX ® 2-73, entitled the ATTENTION-AD trial, for patients who have completed the
48-week Phase 2b/3 placebo-controlled trial referenced above. This trial extension for an additional two years gives patients
the opportunity to continue their treatment. Upon request by patients, caretakers and investigators, this extension trial was
extended by one additional year.
Rett Syndrome
In February 2016, we presented positive preclinical
data for ANAVEX ® 2-73 in Rett syndrome, a rare neurodevelopmental disease. The data demonstrated dose related and
significant improvements in an array of behavioral and gait paradigms in a mouse model with a MECP2-null mutation that causes neurological
symptoms that mimic Rett syndrome. The study was funded by the International Rett Syndrome Foundation (“Rettsyndrome.org”). In January 2017, we were awarded a financial grant
from Rettsyndrome.org of a minimum of $0.6 million to cover some of the costs of a multicenter Phase 2 clinical trial of ANAVEX ® 2-73
for the treatment of Rett syndrome. This award was received in quarterly instalments which commenced during fiscal 2018.
8
In March 2019, we commenced the first Phase
2 clinical trial in a planned Rett syndrome program of ANAVEX ® 2-73 for the treatment of Rett syndrome. The clinical
trials are being conducted in a range of patient age demographics and geographic regions, utilizing an oral liquid once-daily formulation
of ANAVEX ® 2-73.
The first Phase 2 trial, (ANAVEX®2-73-RS-001), which took place in the
United States, was completed in December 2020. This trial was a randomized double-blind, placebo-controlled safety, tolerability, PK and
efficacy trial of oral liquid ANAVEX ® 2-73 formulation in 25 adult female patients with Rett syndrome over a 7-week treatment
period including ANAVEX ® 2-73-specific genomic precision medicine biomarkers. The primary endpoint of the trial was safety.
The dosing of 5 mg ANAVEX ® 2-73 was well-tolerated and demonstrated dose-proportional PK. All secondary efficacy endpoints
of the trial showed statistically significant and clinically meaningful response in the Rett Syndrome Behaviour Questionnaire (“RSBQ”)
response, when compared to placebo, in the intent to treat (“ITT”) cohort (all participants, p = 0.011). 66.7% of ANAVEX ® 2-73
treated subjects showed a statistically significant improvement in RSBQ response as compared to 10% of the subjects on placebo in the
ITT cohort (all participants, p = 0.011). ANAVEX ® 2-73 treatment resulted in a sustained improvement in Clinical Global
Impression Improvement (“CGI-I”) response throughout the 7-week clinical trial, when compared to placebo in the ITT cohort
(all participants, p = 0.014). Consistent with previous ANAVEX ® 2-73 clinical trials, patients carrying the common form
of the SIGMAR1 gene treated with ANAVEX ® 2-73 experienced stronger improvements in the prespecified efficacy endpoints.
The second, international
trial of ANAVEX ® 2-73 for the treatment of Rett syndrome, called the AVATAR trial, commenced in June 2019. This
trial took place in Australia and the United Kingdom using a higher dose than the U.S. based Phase 2 trial for Rett syndrome.
The trial was a Phase 3 randomized, double-blind, placebo-controlled trial to evaluate the safety and efficacy of ANAVEX ® 2-73
in 33 adult patients over a 7-week treatment period including ANAVEX ® 2-73 specific precision medicine biomarkers.
Based upon the input from the successful U.S. Phase 2 Rett syndrome trial (ANAVEX®2-73-RS-001), we updated the endpoints for
the AVATAR trial (ANAVEX®2-73-RS-002) to appropriately assess the clinically meaningful outcome following International Conference
on Harmonization (ICH) guidelines. These updates were approved by the respective regulatory authorities in the U.K. and in Australia,
respectively, where the AVATAR trial was conducted.
The data from the AVATAR trial was released in February 2022. The clinical
trial met all primary and secondary efficacy and safety endpoints, with consistent improvements in primary efficacy endpoint, RSBQ response
(p = 0.037), and secondary efficacy endpoints, ADAMS (p = 0.010) and CGI-I (p = 0.037) response. Efficacy endpoints demonstrated statistically
significant and clinically meaningful reductions in Rett syndrome symptoms. Convenient once daily oral liquid doses of up to 30 mg of
ANAVEX ® 2-73 were also well tolerated with good medication compliance. All patients who participated in the trial were
eligible to receive ANAVEX ® 2-73 under a voluntary open label extension protocol.
In July 2020, we commenced the third trial
of ANAVEX ® 2-73 for the treatment of Rett syndrome, called the EXCELLENCE trial. This Phase 2/3 trial in pediatric
patients with Rett syndrome includes trial sites in Australia, the United Kingdom, and Canada, and will evaluate the safety and
efficacy of ANAVEX ® 2-73 in approximately 84 pediatric patients, aged 5 to 18, over a 12-week treatment period incorporating
ANAVEX ® 2-73 specific precision medicine biomarkers. All patients who participate in the trial will be eligible
to receive ANAVEX ® 2-73 under a voluntary open label extension protocol, which is currently ongoing.
Parkinson’s Disease
In September 2016, we presented positive preclinical
data for ANAVEX ® 2-73 in an animal model of Parkinson’s disease, which demonstrated significant improvements
on behavioral, histopathological, and neuroinflammatory endpoints. The study was funded by the Michael J. Fox Foundation. Additional
data announced in October 2017 indicated that ANAVEX ® 2-73 induced robust neurorestoration in experimental Parkinsonism.
We believe that the encouraging results we have gathered in this preclinical model, coupled with the favorable profile of this
product candidate in the Alzheimer’s disease trial, support the notion that ANAVEX ® 2-73 has the potential
to treat Parkinson’s disease dementia.
9
In October 2020, we completed a double-blind,
randomized, placebo-controlled proof-of-concept Phase 2 trial with ANAVEX ® 2-73 in Parkinson’s disease dementia
in Spain and Australia, to study the effect of the compound on both the cognitive and motor impairment of Parkinson’s disease.
The Phase 2 trial enrolled approximately 132 patients for 14 weeks, randomized 1:1:1 to two different ANAVEX ® 2-73
doses, 30 mg and 50 mg, or placebo. The ANAVEX ® 2-73 Phase 2 Parkinson’s disease dementia trial design incorporated
genomic precision medicine biomarkers identified in the ANAVEX ® 2-73 Phase 2a Alzheimer’s disease trial.
The trial demonstrated that ANAVEX ® 2-73
was safe and well tolerated in oral doses up to 50 mg once daily. The results showed clinically meaningful, dose-dependent, and
statistically significant improvements in the Cognitive Drug Research (“CDR”) computerized assessment system analysis.
Treatment with ANAVEX ® 2-73 also resulted in clinically meaningful improvements as measured by the global composite
score of Parkinson’s disease symptom severity, MDS-Unified Parkinson’s Disease Rating Scale total score on top of standard
of care including dopaminergic therapy, levodopa and other anti-PD medications after 14 weeks of treatment, suggesting ANAVEX ® 2-73’s
potential capability of slowing and reversing symptoms that progress in Parkinson’s disease. In addition, the trial confirmed
the precision medicine approach of targeting SIGMAR1 as a genetic biomarker in response to ANAVEX ® 2-73 may result
in improved clinical outcomes.
In January 2021, we were awarded a research
grant of $1.0 million from The Michael J. Fox Foundation for Parkinson’s Research to develop ANAVEX ® 2-73
for the treatment of Parkinson’s disease. The award will explore utilization of PET imaging biomarkers to enable measurement
of target engagement and pathway activation of the SIGMAR1 with clinically relevant doses in people with Parkinson’s disease.
Frontotemporal Dementia
In July 2020, we commenced the First-in-Human
Phase 1 clinical trial of ANAVEX ® 3-71. ANAVEX ® 3-71 was previously granted orphan drug designation
for the treatment of Frontotemporal Dementia (“FTD”) by the FDA. ANAVEX ® 3-71 is an orally administered small molecule
targeting sigma-1 and M1 muscarinic receptors that is designed to be beneficial for neurodegenerative diseases. In preclinical
studies, ANAVEX ® 3-71 demonstrated disease-modifying activity against the major hallmarks of Alzheimer’s disease
in transgenic (3xTg-AD) mice, including cognitive deficits, amyloid and tau pathologies, as well as beneficial effects on mitochondrial
dysfunction and neuroinflammation.
The Phase 1 clinical trial was a prospective
double-blind, randomized, placebo-controlled trial in Australia. A total of 36 healthy male and female subjects were included.
Single escalating doses of ANAVEX ® 3-71 were administered in order to evaluate the safety, tolerability, and PK of
ANAVEX ® 3-71 and the effects of food and gender on its PK in healthy volunteers.
The trial met its primary and secondary endpoints
of safety, with no serious adverse events (“SAEs”) or dose-limiting toxicities observed. ANAVEX ® 3-71
was well tolerated in all cohorts receiving ANAVEX ® 3-71 in single doses ranging from 5 mg to 200 mg daily with no
SAEs and no significant lab abnormalities in any subject. In the trial, ANAVEX ® 3-71 exhibited linear PK. Its pharmacokinetics
was also dose proportional for doses up to 160 mg. Gender had no effect on the PK of the drug and food had no effect on the bioavailability
of ANAVEX ® 3-71. The trial also met the secondary objective of characterizing the effect of ANAVEX ® 3-71
on electrocardiogram (“ECG”) parameters. There were no clinically significant ECG parameters throughout the trial.
Participant QTcF measures were normal across all dose groups with no difference between ANAVEX ® 3-71 and placebo.
Based on these results, and ANAVEX ® 3-71’s
pre-clinical profile, we intend to advance ANAVEX ® 3-71 into a biomarker-driven clinical development dementia program
for the treatment of schizophrenia, FTD and Alzheimer’s disease, evaluating longitudinal effect of treatment with ANAVEX ® 3-71.
We believe the results of these clinical trials and preclinical study could serve as the basis for advancing into respective registration
studies in the U.S.

Our Pipeline
Our research and development pipeline includes
ANAVEX ® 2-73 currently in three different clinical trial indications, and several other compounds in different stages
of clinical and pre-clinical development.
Our proprietary SIGMACEPTOR™ Discovery
Platform produced small molecule drug candidates with unique modes of action, based on our understanding of sigma receptors. Sigma
receptors may be targets for therapeutics to combat many human diseases, both of neurodegenerative nature, including Alzheimer’s
disease, as well as of neurodevelopmental nature, like Rett syndrome. When bound by the appropriate ligands, sigma receptors influence
the functioning of multiple biochemical signals that are involved in the pathogenesis (origin or development) of disease. Multiple
viruses including SARS-CoV-2 (COVID-19) induce cellular stress by intrinsic mitochondrial apoptosis and other related cellular
processes, in order to ensure survival and replication. Hence, it is possible that SIGMAR1 could play a role in modulating the
cellular response to viral infection and ameliorate pathogenesis.
Compounds that have been subjects of our research
include the following:
ANAVEX ® 2-73 (blarcamesine)
We believe ANAVEX ® 2-73 may offer
a disease-modifying approach in neurodegenerative and neurodevelopmental diseases by activation of SIGMAR1. ANAVEX ® 2-73
is being developed in an oral liquid once-daily formulation for rare diseases such as Rett syndrome as well as an oral once-daily
capsule formulation for diseases such as Alzheimer’s disease.
In Rett syndrome, administration of ANAVEX ® 2-73
in liquid form resulted in both significant and dose related improvements in an array of behavioral paradigms in the MECP2 HET
Rett syndrome disease model. In addition, in a further experiment sponsored by Rettsyndrome.org, ANAVEX ® 2-73 was
evaluated in automatic visual response and respiration tests in 7-month old mice, an age at which advanced pathology is evident.
Vehicle-treated MECP2 mice demonstrated fewer automatic visual responses than wild-type mice. Treatment with ANAVEX ® 2-73
for four weeks significantly increased the automatic visual response in the MECP2 Rett syndrome disease mice. Additionally, chronic
oral dosing daily for 6.5 weeks of ANAVEX ® 2-73 starting at ~5.5 weeks of age was conducted in the MECP2 HET Rett
syndrome disease mouse model assessed the different aspects of muscular coordination, balance, motor learning and muscular strengths,
some of the core deficits observed in Rett syndrome. Administration of ANAVEX ® 2-73 resulted in both significant
and dose related improvements in an array of these behavioral paradigms in the MECP2 HET Rett syndrome disease model.
In May 2016 and June 2016, the FDA granted
Orphan Drug Designation to ANAVEX ® 2-73 for the treatment of Rett syndrome and infantile spasms, respectively. In
November 2019, the FDA granted to ANAVEX ® 2-73 the Rare Pediatric Disease (RPD) designation for the treatment of
Rett syndrome. The RPD designation is intended to encourage the development of treatments for rare pediatric diseases.
Further, in February 2020, the FDA granted
Fast Track designation for the ANAVEX ® 2-73 clinical development program for the treatment of Rett syndrome. The
FDA Fast Track program is designed to facilitate and expedite the development and review of new drugs to address unmet medical
needs in the treatment of serious and life-threatening conditions.
For Parkinson’s disease, data demonstrates
significant improvements and restoration of function in a disease modifying animal model of Parkinson’s disease. Significant
improvements were seen on all measures tested: behavioral, histopathological, and neuroinflammatory endpoints. In October 2020,
we completed a double-blind, randomized, placebo-controlled proof-of-concept Phase 2 trial with ANAVEX ® 2-73 in Parkinson’s
disease dementia, to study the effect of the compound on both the cognitive and motor impairment of Parkinson’s disease.
The Phase 2 trial enrolled approximately 132 patients for 14 weeks, randomized 1:1:1 to two different ANAVEX ® 2-73
doses, 30 mg and 50 mg, or placebo. The ANAVEX ® 2-73 Phase 2 Parkinson’s disease dementia trial design incorporated
genomic precision medicine biomarkers identified in the ANAVEX ® 2-73 Phase 2a Alzheimer’s disease trial.
11
The trial demonstrated that ANAVEX ® 2-73
was safe and well tolerated in oral doses up to 50 mg once daily. The results showed clinically meaningful, dose-dependent, and
statistically significant improvements in the CDR computerized assessment system analysis. We anticipate conducting further clinical
trials of ANAVEX ® 2-73 in Parkinson’s disease dementia after submitting the results of the trial to the FDA
to obtain regulatory guidance.
In Alzheimer’s disease animal models,
ANAVEX ® 2-73 has shown pharmacological, histological and behavioral evidence as a potential neuroprotective, anti-amnesic,
anti-convulsive and anti-depressive therapeutic agent, due to its potent affinity to SIGMAR1 and moderate affinities to M1-4 type
muscarinic receptors. In addition, ANAVEX ® 2-73 has shown a potential dual mechanism which may impact amyloid, tau
pathology and inflammation. In a transgenic Alzheimer’s disease animal model Tg2576, ANAVEX ® 2-73 induced a
statistically significant neuroprotective effect against the development of oxidative stress in the mouse brain, as well as significantly
increased the expression of functional and synaptic plasticity markers that is apparently amyloid-beta independent. It also statistically
alleviated the learning and memory deficits developed over time in the animals, regardless of sex, both in terms of spatial working
memory and long-term spatial reference memory.
Based on the results of pre-clinical testing,
we initiated and completed a Phase 1 single ascending dose (SAD) clinical trial of ANAVEX ® 2-73. In this Phase 1
SAD trial, the maximum tolerated single dose was defined per protocol as 55-60 mg. This dose is above the equivalent dose shown
to have positive effects in mouse models of Alzheimer’s disease. There were no significant changes in laboratory or ECG parameters.
ANAVEX ® 2-73 was well tolerated below the 55-60 mg dose with only mild adverse events in some subjects. Observed
adverse events at doses above the maximum tolerated single dose included headache and dizziness, which were moderate in severity
and reversible. These side effects are often seen with drugs that target CNS conditions, including Alzheimer’s disease.
In November 2016, we completed a Phase 2a clinical
trial for ANAVEX ® 2-73, for the treatment of Alzheimer’s disease. The open-label randomized trial was designed
to assess the safety and exploratory efficacy of ANAVEX ® 2-73 in 32 patients with mild-to-moderate Alzheimer’s
disease. The Phase 2a trial met both primary and secondary objectives of the trial.
In July 2018, we presented
the results of a genomic DNA and RNA evaluation of the participants in the Phase 2a clinical trial. More than 33,000 genes were
analyzed using unbiased, data driven, machine learning, artificial intelligence (AI) system for analyzing DNA and RNA data in patients
treated with ANAVEX ® 2-73. The analysis identified genetic variants that impacted response to ANAVEX ® 2-73,
among them variants related to the SIGMAR1, the target for ANAVEX ® 2-73. Results showed that trial participants with
the common SIGMAR1 wild type gene variant, which is estimated to be about 80% of the population worldwide, demonstrated improved
cognitive (MMSE) and the functional (ADCS-ADL) scores. The results from this evaluation supported the continued evaluation of genomic
information in subsequent clinical trials, since these signatures can now be applied to neurological indications tested in future
clinical trials with ANAVEX ® 2-73 including Alzheimer’s disease, Parkinson’s disease dementia and Rett
syndrome.
ANAVEX ® 2-73
data met prerequisite information in order to progress into a Phase 2b/3 placebo-controlled trial. On July 2, 2018, the Human Research
Ethics Committee in Australia approved the initiation of our Phase 2b/3, double-blind, randomized, placebo-controlled 48-week safety
and efficacy trial of ANAVEX ® 2-73 for the treatment of early Alzheimer’s disease. Clinical trial sites in
Canada, the United Kingdom, the Netherlands and Germany were also added. This Phase 2b/3 trial design incorporates inclusion of
genomic precision medicine biomarkers identified in the ANAVEX ® 2-73 Phase 2a trial. The Phase 2b/3 trial, which
has completed enrollment, randomized 1:1:1 to either two different ANAVEX ® 2-73 doses or placebo.
We believe preclinical data from our studies
also supports ANAVEX ® 2-73 as a potential platform drug for other neurodegenerative diseases beyond Alzheimer’s
disease, Parkinson’s disease or Rett syndrome, more specifically, epilepsy, infantile spasms, Fragile X syndrome, Angelman
syndrome, multiple sclerosis and, more recently, tuberous sclerosis complex (TSC). ANAVEX ® 2-73 demonstrated significant
improvements in all of these indications in the respective preclinical animal models.
12
In a preclinical study sponsored by the Foundation
for Angelman Syndrome, ANAVEX ® 2-73 was assessed in a mouse model for the development of audiogenic seizures. The
results indicated that ANAVEX ® 2-73 administration significantly reduced audiogenic-induced seizures. In a study
sponsored by FRAXA Research Foundation regarding Fragile X syndrome, data demonstrated that ANAVEX ® 2-73 restored
hippocampal brain-derived neurotrophic factor (BDNF) expression to normal levels. BDNF under-expression has been observed in many
neurodevelopmental and neurodegenerative pathologies. BDNF signaling promotes maturation of both excitatory and inhibitory synapses.
ANAVEX ® 2-73 normalization of BDNF expression could be a contributing factor for the positive data observed in both
neurodevelopmental and neurodegenerative disorders like Angelman and Fragile X syndromes.
In addition, preclinical data to-date also
indicates that ANAVEX ® 2-73 has the potential to demonstrate protective effects of mitochondrial enzyme complexes
during pathological conditions, which, if impaired, are believed to play a role in the pathogenesis of neurodegenerative and neurodevelopmental
diseases.
In addition, preclinical data on ANAVEX ® 2-73
related to multiple sclerosis indicates that ANAVEX ® 2-73 may promote remyelination in multiple sclerosis disease.
Further, our data also demonstrates that ANAVEX ® 2-73 has the potential to provide protection for oligodendrocytes
(“OL’s”) and oligodendrocyte precursor cells (“OPC’s”), as well as central nervous system neurons
in addition to helping repair by increasing OPC proliferation and maturation in tissue culture.
In March 2018, we presented preclinical data
of ANAVEX ® 2-73 in a genetic mouse model of tuberous sclerosis complex (“TSC”). TSC is a rare genetic
disorder characterized by the growth of numerous benign tumors in many parts of the body with a high incidence of seizures. The
preclinical data demonstrated that treatment with ANAVEX ® 2-73 significantly increased survival and reduced seizures
in those mice.
ANAVEX ® 3-71
ANAVEX ® 3-71 is a clinical drug
candidate with a novel mechanism of action via SIGMAR1 activation and M1 muscarinic allosteric modulation, which has been shown
to enhance neuroprotection and cognition in Alzheimer’s disease models. ANAVEX ® 3-71 is a CNS-penetrable potential
disease modifying treatment for cognitive impairments. We believe it is effective in very small doses against the major Alzheimer’s
hallmarks in transgenic (3xTg-AD) mice, including cognitive deficits, amyloid and tau pathologies, and also has beneficial effects
on inflammation and mitochondrial dysfunctions. ANAVEX ® 3-71 indicates extensive therapeutic advantages in Alzheimer’s
and other protein-aggregation-related diseases given its ability to enhance neuroprotection and cognition via SIGMAR1 activation
and M1 muscarinic allosteric modulation.
A preclinical study examined the response of
ANAVEX ® 3-71 in aged transgenic animal models and showed a significant reduction in the rate of cognitive deficit,
amyloid beta pathology and inflammation with the administration of ANAVEX 3-71. In April 2016, the FDA granted Orphan Drug Designation
to ANAVEX ® 3-71 for the treatment of FTD.
During pathological conditions ANAVEX ® 3-71
demonstrated the formation of new synapses between neurons (synaptogenesis) without causing an abnormal increase in the number
of astrocytes. In neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease, synaptogenesis is believed
to be impaired. Additional preclinical data presented also indicates that in addition to reducing oxidative stress, ANAVEX ® 3-71
has the potential to demonstrate protective effects of mitochondrial enzyme complexes during pathological conditions, which, if
impaired, are believed to play a role in the pathogenesis of neurodegenerative and neurodevelopmental diseases.
13
In July 2020, we commenced the first Phase
1 clinical trial of ANAVEX ® 3-71. The trial took place in Australia and was a double-blind, randomized, placebo-controlled,
Phase 1 trial to evaluate safety and tolerability, and PK of oral escalating doses of ANAVEX ® 3-71 including effects
of food and gender in healthy volunteers. The trial met its primary and secondary endpoints of safety, respectively with no serious
adverse events (SAEs) or dose-limiting toxicities observed, as more fully described above under Clinical Trials Overview –
Frontotemporal Dementia .
Based on these results, and ANAVEX ® 3-71
pre-clinical profile, the Company intends to advance ANAVEX ® 3-71 into a biomarker-driven clinical development dementia
program for the treatment of schizophrenia, FTD and Alzheimer’s disease, evaluating longitudinal effect of treatment with
ANAVEX ® 3-71. We believe the results of this clinical trial and preclinical study could serve as a basis for advancing
into respective registration trials in the U.S.
ANAVEX ® 1-41
ANAVEX ® 1-41 is a sigma-1 agonist.
Pre-clinical tests revealed significant neuroprotective benefits (i.e., protects nerve cells from degeneration or death) through
the modulation of endoplasmic reticulum, mitochondrial and oxidative stress, which damages and impairs cell viability. In addition,
in animal models, ANAVEX ® 1-41 prevented the expression of caspase-3, an enzyme that plays a key role in apoptosis
(programmed cell death) and loss of cells in the hippocampus, the part of the brain that regulates learning, emotion and memory.
These activities involve both muscarinic and SIGMAR1 systems through a novel mechanism of action.
Preclinical data presented also indicates that
ANAVEX ® 1-41 has the potential to demonstrate protective effects of mitochondrial enzyme complexes during pathological
conditions, which, if impaired, are believed to play a role in the pathogenesis of neurodegenerative and neurodevelopmental diseases.
ANAVEX ® 1066
ANAVEX ® 1066, a mixed
sigma-1/sigma-2 ligand is designed for the potential treatment of neuropathic and visceral pain. ANAVEX ® 1066 was
tested in two preclinical models of neuropathic and visceral pain that have been extensively validated in rats. In the chronic
constriction injury model of neuropathic pain, a single oral administration of ANAVEX ® 1066 dose-dependently restored
the nociceptive threshold in the affected paw to normal levels while leaving the contralateral healthy paw unchanged. Efficacy
was rapid and remained significant for two hours. In a model of visceral pain, chronic colonic hypersensitivity was induced by
injection of an inflammatory agent directly into the colon and a single oral administration of ANAVEX ® 1066 returned
the nociceptive threshold to control levels in a dose-dependent manner. Companion studies in rats demonstrated the lack of any
effects on normal gastrointestinal transit with ANAVEX ® 1066 and a favorable safety profile in a battery of behavioral
measures.
ANAVEX ® 1037
ANAVEX ® 1037 is designed for
the treatment of prostate and pancreatic cancer. It is a low molecular weight, synthetic compound exhibiting high affinity for
SIGMAR1 at nanomolar levels and moderate affinity for sigma-2 receptors and sodium channels at micromolar levels. In advanced pre-clinical
studies, this compound revealed antitumor potential. It has also been shown to selectively kill human cancer cells without affecting
normal/healthy cells and also to significantly suppress tumor growth in immune-deficient mice models. Scientific publications highlight
the possibility that these ligands may stop tumor growth and induce selective cell death in various tumor cell lines. Sigma receptors
are highly expressed in different tumor cell types. Binding by appropriate sigma-1 and/or sigma-2 ligands can induce selective
apoptosis. In addition, through tumor cell membrane reorganization and interactions with ion channels, we believe our drug candidates
may play an important role in inhibiting the processes of metastasis (spreading of cancer cells from the original site to other
parts of the body), angiogenesis (the formation of new blood vessels) and tumor cell proliferation.
ANAVEX ® 1037 is currently in
the pre-clinical and clinical testing stages of development, and there is no guarantee that the activity demonstrated in pre-clinical
models will be shown in human testing.

We continue to identify and initiate discussions
with potential strategic and commercial partners to most effectively advance our programs and increase stockholder value. Further,
we may acquire or develop new intellectual property and assign, license, or otherwise transfer our intellectual property to further
our goals.
Our Target Indications
We are developing compounds with potential
application to two broad categories and several specific indications, including:
Central Nervous System Diseases
●
Alzheimer’s disease – In 2022, an estimated 6.5 million Americans were suffering from Alzheimer’s disease. The Alzheimer’s Association ® estimates that by 2050, this number is expected to rise to 12.7 million Americans. Medications on the market today treat only the symptoms of Alzheimer’s disease and do not have the ability to stop its onset or its progression. We believe there is an urgent and unmet need for both a disease modifying cure for Alzheimer’s disease as well as for better symptomatic treatments.
●
Parkinson’s disease – Parkinson’s disease is a progressive disease of the nervous system marked by tremors, muscular rigidity, and slow, imprecise movement. It is associated with degeneration of the basal ganglia of the brain and a deficiency of the neurotransmitter dopamine. Parkinson’s disease currently is estimated to afflict more than 10 million people worldwide, typically middle-aged and elderly people. The Parkinson’s disease market is expected to reach to $11.5 billion by 2029, according to GlobalData.
●
Rett syndrome – Rett
syndrome is a rare X-linked genetic neurological and developmental disorder that affects the way the brain develops, including protein
transcription, which is altered and as a result leads to severe disruptions in neuronal homeostasis. It is considered a rare, progressive
neurodevelopmental disorder and is caused by a single mutation in the MECP2 gene. Because males have a different chromosome combination
from females, boys who have the genetic MECP2 mutation are affected in devastating ways. Most of them die before birth or in early
infancy. For females who survive infancy, Rett syndrome leads to severe impairments, affecting nearly every aspect of the child’s
life; severe mental retardation, their ability to speak, walk and eat, sleeping problems, seizures and even the ability to breathe
easily. Rett syndrome affects approximately 1 in every 10,000-15,000 females.
●
Depression – Depression is a major cause of morbidity worldwide according to the World Health Organization. The global antidepressant drug market is projected to reach $21 Billion by 2030 according to Allied Market Research. Pharmaceutical treatment for depression has been historically dominated by blockbuster brands. However, the dominance of the leading brands is waning, largely due to an increase in the number of approvals for antidepressant drugs.
●
Epilepsy – Epilepsy
is a common chronic neurological disorder characterized by recurrent unprovoked seizures. These seizures are transient signs and/or
symptoms of abnormal, excessive or synchronous neuronal activity in the brain. According to the Centers for Disease Control and Prevention,
in 2015 epilepsy affected 3.4 million Americans. Today, epilepsy is often controlled, but not cured, with medication that is categorized
as older traditional anti-epileptic drugs and second generation anti-epileptic drugs. Because epilepsy afflicts sufferers in different
ways, there is a need for drugs used in combination with both traditional anti-epileptic drugs and second generation anti-epileptic
drugs.
●
Neuropathic Pain –
We define neuralgia, or neuropathic pain, as pain that is not related to activation of pain receptor cells in any part of the body.
Neuralgia is more difficult to treat than some other types of pain because it does not respond well to normal pain medications. Special
medications have become more specific to neuralgia and typically fall under the category of membrane stabilizing drugs or antidepressants.
15
Cancer
●
Malignant Melanoma – Predominantly a skin cancer, malignant melanoma can also occur in melanocytes found in the bowel and the eye. Malignant melanoma accounts for a large majority of skin cancer deaths. The treatment includes surgical removal of the tumor, adjuvant treatment, chemo and immunotherapy, or radiation therapy. According to iHealthcareAnalyst, Inc. the worldwide malignant melanoma market is expected to grow to $7.5 billion by 2029.
●
Prostate Cancer
– Specific to men, prostate cancer is a form of cancer that develops in the prostate, a gland in the male reproductive
system. Cancer cells may metastasize from the prostate to other parts of the body, particularly the bones and lymph nodes.
Drug therapeutics for prostate cancer are expected to increase to nearly $10.1 billion by the end of 2030 according to Market
Research Future.
●
Pancreatic Cancer
– Pancreatic cancer is a malignant neoplasm of the pancreas. In the United States, approximately 62,000 new cases of
pancreatic cancer will be diagnosed this year and approximately 50,000 patients will die as a result of their cancer, according
to the American Cancer Society. Sales predictions by Market Data Forecast predict that the market for the global pharmaceutical
treatment of pancreatic cancer will increase from $2.59 billion in 2022 to $3.73 billion by 2027.
Competition
The drug discovery and development industry
is very competitive, characterized by rapid advancements in technology, where protection of proprietary advancements is essential.
Any product candidates that we may successfully develop and commercialize, may compete with existing therapies, or new therapies
that may become available in the future. Our commercial opportunities could be reduced or eliminated if our competitors develop
and commercialize products that are more effective, have fewer side effects, are more convenient or are less expensive than any
products that we may develop.
We believe our approach to the treatment of
Alzheimer’s disease and other CNS diseases differs from our competitors - our platform may offer a disease-modifying approach
in neurodegenerative and neurodevelopmental diseases by activation of SIGMAR1. In our preclinical studies, when activated by SIGMAR1
agonists, such as ANAVEX ® 2-73, SIGMAR1 demonstrated reduced cellular stress before and after RNA gene transcription.
Our studies confirm the potential existence of a predictive biomarker of response established through SIGMAR1 mRNA expression that
could be used in future clinical trials. Because of its role in maintaining neuronal homeostasis, we believe sigma receptors show
significant promise as viable targets for therapeutic molecules in an effort to treat Alzheimer’s disease and other CNS diseases
and disorders, including Parkinson’s disease and Rett syndrome, by restoring healthy gene expression.
At this time, our competitors are primarily
other biomedical development companies that are aiming to discover and develop compounds to be used in the treatment of Alzheimer’s
disease and other CNS diseases, and those companies already doing so. We also face competition from academic institutions and government
agencies, both in the United States and abroad.
Our competitors may have significantly greater
financial resources, an established presence in the market, expertise in research and development, manufacturing, preclinical and
clinical testing, may be in the process of obtaining regulatory approvals and marketing of approved products. These competitors
also compete with us in recruiting and retaining qualified scientific and technical personnel, establishing clinical trial sites
and patient registration for clinical trials, as well as in acquiring or developing technologies complementary to, or necessary
for, our programs. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative
arrangements with large and established companies.
For additional discussion of the risks
related to competition, see Item 1A “Risk Factors.”

South Africa, which are expected to expire in January 2030.
17
We also own other patent applications
directed to enantiomers, crystals, formulations, uses, and patient selection methods that may provide additional protection for
one or more of our product candidates.
We regard patents and other intellectual
property rights as corporate assets. Accordingly, we attempt to optimize the value of intellectual property in developing our business
strategy including the selective development, protection, and exploitation of our intellectual property rights. In addition to
filings made with intellectual property authorities, we protect our intellectual property and confidential information by means
of carefully considered processes of communication and the sharing of information, and by the use of confidentiality and non-disclosure
agreements and provisions for the same in contractor’s agreements. While no agreement offers absolute protection, such agreements
provide some form of recourse in the event of disclosure, or anticipated disclosure.
Our intellectual property position,
like that of many biomedical companies, is uncertain and involves complex legal and technical questions for which important legal
principles are unresolved. For more information regarding challenges to our existing or future patents, see “Risk Factors”.
Government regulation
Government authorities in the United
States, at the federal, state and local levels, and other countries extensively regulate, among other things, the research, development,
testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution,
marketing and export and import of products such as those we are developing. A new drug must be approved by the FDA through the
NDA or ANDA process before it may be legally marketed in the United States. We are subject to various government regulations in
connection with the development of our pipeline.
U.S. Drug Development and Regulation
In the United States, the FDA regulates drugs
under the Federal Food, Drug, and Cosmetic Act and its implementing regulations (“FDCA”). The process of obtaining
regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations
require 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 post approval may subject an applicant to administrative or
judicial sanctions. These sanctions could include the FDA’s refusal to approve pending applications, withdrawal of an approval,
import refusal, a clinical hold, warning letters, product recalls, product seizures, total or partial suspension of production
or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties.
Any agency or judicial enforcement action could have a material adverse effect on us.
Once a drug candidate is identified for development,
it enters the preclinical testing stage and an Investigational New Drug Application (“IND”) may be opened for the regulatory
development of the product. Preclinical tests include laboratory evaluations of product chemistry, toxicity and formulation, as
well as other preclinical studies. An IND sponsor must submit the results of the preclinical tests, together with manufacturing
information and analytical data, to the FDA as part of the IND to conduct clinical trials. The sponsor must also include a protocol
detailing, among other things, the objectives of the first phase of clinical trials, the parameters to be used in monitoring the
safety of the trial, and the effectiveness criteria to be evaluated should the first phase lend itself to an efficacy evaluation.
Some preclinical testing may continue even after the IND is filed. The IND automatically becomes effective thirty (30) days after
receipt by the FDA, unless the FDA, within the 30-day time period, places the clinical trial on a clinical hold. Clinical holds
also may be imposed by the FDA at any time before or during clinical trials due to safety concerns about ongoing or proposed clinical
trials or non-compliance with specific FDA requirements, and the trials may not begin or continue until the FDA notifies the sponsor
that the hold has been lifted.
18
All clinical trials must be conducted under
the supervision of one or more qualified investigators in accordance with FDA good clinical practice (“GCP”) requirements,
which include a requirement that all research subjects provide their informed consent in writing for their participation in any
clinical trial. Clinical trials must be conducted under protocols detailing the objectives of the trial, dosing procedures, subject
selection inclusion and exclusion criteria and the safety and/or effectiveness criteria to be evaluated. Each protocol must be
submitted to the FDA as part of the IND, and timely safety reports must be submitted to the FDA and the investigators for serious
and unexpected adverse events. An Institutional Review Board (“IRB”) at each institution participating in the clinical
trial must review and approve each protocol before a clinical trial may commence at the institution and must also approve the information
regarding the trial as well as the informed consent form that must be provided to each trial participant or his or her legal representative,
monitor the study until completed and otherwise comply with all applicable IRB regulations.
Human clinical trials are typically conducted
in three sequential phases that may overlap or be combined in certain cases:
Phase 1: The compound is initially introduced
into healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism, distribution and excretion and, if
possible, to gain an early indication of its effectiveness. In most cases, initial Phase 1 clinical trials are conducted with healthy
volunteers. However, where the compound being evaluated is for the treatment of severe or life-threatening diseases, such as cancer,
and especially when the product may be too toxic to ethically administer to healthy volunteers, the initial human testing may be
conducted on patients with the target disease or condition. Sponsors sometimes subdivide their Phase 1 clinical trials into Phase
1a and Phase 1b clinical trials. Phase 1b clinical trials are typically aimed at confirming dosage, PK and safety in a larger number
of patients. Some Phase 1b clinical trials evaluate biomarkers or surrogate markers that may be associated with efficacy in patients
with specific types of diseases or conditions.
Phase 2: This phase involves clinical trials
in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of
the product for specific targeted diseases or conditions and to confirm dosage tolerance and appropriate dosage.
Phase 3: Phase 3 clinical trials are undertaken
to further evaluate dosage, clinical efficacy and safety in an expanded patient population, generally at geographically dispersed
clinical trial sites. These clinical trials, often referred to as “pivotal” or “confirmatory” clinical
trials, are intended to establish the overall risk-benefit ratio of the compound and provide, if appropriate, an adequate basis
for product approval and labeling.
The FDA or the sponsor may suspend a clinical
trial at any time on various grounds, including any finding that the research subjects or patients are being exposed to an unacceptable
health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution 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 study subjects. In addition, clinical trials may be overseen by an independent group of qualified experts organized by
the sponsor, known as a data safety monitoring board or committee. Depending on its charter, this board or committee may determine
whether a trial may move forward at designated check points based on access to certain data from the trial.
Phase 4: Phase 4 or post-approval trials may
also be conducted after a drug receives initial marketing approval. These trials, often referred to as “Phase 4” trials,
are used to gain additional experience from the treatment of patients in the intended therapeutic indication. In certain instances,
the FDA may mandate the performance of such clinical trials as a condition of approval of continued marketing of the product.
During the development of a new drug, sponsors
are given several opportunities to meet with the FDA. These meetings can provide an opportunity for the sponsor to share information
about the progress of the application or clinical trials, for the FDA to provide advice, and for the sponsor and the FDA to reach
agreement on the next phase of development. These meetings may occur prior to the submission of an IND, at the end of Phase 2 clinical
trials, or before an NDA is ultimately submitted. Sponsors typically use the meetings at the end of the Phase 2 trials to discuss
Phase 2 clinical results and present plans for the pivotal Phase 3 clinical trials that they believe will support approval of the
new drug. Meetings at other times may be made upon request and are subject to approval by the FDA.
19
Concurrent with clinical trials, companies
typically complete additional, animal or other non-clinical studies, develop additional information about the chemistry and physicochemical
characteristics of the drug, and finalize a process for manufacturing the product in commercial quantities in accordance with the
FDA’s current Good Manufacturing Practices (“cGMP”) requirements. The manufacturing process must consistently
produce quality batches of the drug and, among other things, the manufacturer must develop methods for testing the identity, strength,
quality and purity of the final drug. In addition, appropriate packaging must be selected and tested, and stability studies must
be conducted to demonstrate the effectiveness of the packaging and that the compound does not undergo unacceptable deterioration
over its shelf life.
While the IND is active, progress reports summarizing
the results of ongoing clinical trials and nonclinical studies performed since the last progress report must be submitted on at
least an annual basis to the FDA, and written IND safety reports must be submitted to the FDA and investigators for serious and
unexpected adverse events, findings from other studies suggesting a significant risk to humans exposed to the same or similar drugs,
findings from animal or in vitro testing suggesting a significant risk to humans, and any clinically important, increased incidence
of a serious adverse reaction compared to that listed in the protocol or investigator brochure.
There are also requirements governing the submission
of certain clinical trials and completed trial results to public registries. Sponsors of certain clinical trials of FDA-regulated
products are required to register and disclose specified clinical trial registration and results information, which is made publicly
available at www.clinicaltrials.gov. Failure to properly report clinical trial results can result in civil monetary penalties.
Disclosure of clinical trial results can often be delayed until the new product or new indication being studied has been approved.
U.S. review and approval process
The results of product development, preclinical
and other non-clinical studies and clinical trials, along with descriptions of the manufacturing process, analytical tests conducted
on the chemistry of the drug, proposed labeling and other relevant information are submitted to the FDA as part of a New Drug Application
(“NDA”). The submission of an NDA is subject to the payment of substantial user fees; a waiver of which may be obtained
under certain limited circumstances.
The FDA reviews NDAs to determine, among
other things, whether the product is safe and effective for its intended use and whether it is manufactured in a cGMP-compliant
manner, which will assure and preserve the product’s identity, strength, quality and purity. Under the Prescription Drug
User Fee Act (“PDUFA”), the FDA has a goal of ten months from the date of “filing” of a standard, completed
NDA for a new molecular entity to review and act on the submission. This review typically takes twelve months from the date the
NDA is submitted to the FDA because the FDA has approximately two months to make a “filing” decision after the application
is submitted. The FDA conducts a preliminary review of all NDAs within the first sixty days after submission, before accepting
them for filing, to determine whether they are sufficiently complete to permit substantive review. The FDA may request additional
information rather than accept an NDA for filing. In this event, the NDA must be resubmitted with the additional information. The
resubmitted application also is subject to review before the FDA accepts it for filing.
The FDA may refer an application for a new
drug to an advisory committee. 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 and under what conditions the application should be
approved. The FDA is not bound by the recommendations of such an advisory committee, but it considers advisory committee recommendations
carefully when making decisions.
20
Before approving an NDA, the FDA will also
inspect the facility where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing
processes and facilities are in compliance with cGMP requirements and are adequate to assure consistent production of the product
within required specifications. Before approving an NDA, the FDA may also inspect one or more clinical trial sites to assure compliance
with GCP requirements and inspect the clinical trial records.
After the FDA evaluates an NDA, it will issue
an approval letter or a Complete Response Letter. A Complete Response Letter indicates that the review cycle of the application
is complete, and the application will not be approved in its present form. A Complete Response Letter usually describes the specific
deficiencies in the NDA identified by the FDA and may require additional clinical data, such as an additional pivotal Phase 3 trial
or other significant and time-consuming requirements related to clinical trials, nonclinical studies or product manufacturing.
If a Complete Response Letter is issued, the sponsor must resubmit the NDA, addressing all of the deficiencies identified in the
letter, or withdraw the application. Even if such data and information are submitted, the FDA may decide that the NDA does not
satisfy the criteria for approval. An approval letter authorizes commercial marketing of the drug with prescribing information
for specific indications.
The Pediatric Research Equity Act (“PREA”),
requires IND sponsors to conduct pediatric clinical trials for most drugs, for a new active ingredient, new indication, new dosage
form, new dosing regimen or new route of administration. Under PREA, original NDAs and supplements must contain a pediatric assessment
unless the sponsor has received a deferral or waiver. The required assessment must evaluate the safety and effectiveness of the
product for the claimed indications in all relevant pediatric subpopulations and support dosing and administration for each pediatric
subpopulation for which the product is safe and effective. The sponsor or the FDA may request a deferral of pediatric clinical
trials for some or all of the pediatric subpopulations. A deferral may be granted for several reasons, including a finding that
the drug is ready for approval for use in adults before pediatric clinical trials are complete or that additional safety or effectiveness
data needs to be collected before the pediatric clinical trials begin. The FDA must send a non-compliance letter to any sponsor
that fails to submit the required assessment, keep a deferral current or fails to submit a request for approval of a pediatric
formulation.
If a drug receives FDA approval, the approval
may be limited to specific diseases and dosages, which could restrict the commercial value of the product. In addition, the FDA
may require testing and surveillance programs to monitor the safety of approved products which have been commercialized and may
require a sponsor to conduct post-marketing clinical trials (Phase 4 clinical trials), which are designed to further assess a drug’s
safety and effectiveness after NDA approval. The FDA may also place other conditions on approval, including a requirement for a
risk evaluation and mitigation strategy (“REMS”) to assure the safe use of the drug. If the FDA concludes a REMS is
needed, the sponsor of the NDA must submit a proposed REMS. The FDA will not approve the NDA without an approved REMS, if required.
A REMS could include medication guides, physician communication plans or elements to assure safe use, such as restricted distribution
methods, patient registries and other risk minimization tools. Any of these limitations on approval or marketing could restrict
the commercial promotion, distribution, prescribing or dispensing of products. Marketing approval may be withdrawn for non-compliance
with REMS or other regulatory requirements, or if problems occur following initial marketing.
Post-approval requirements
Once an approval is granted, the FDA may withdraw
the approval if compliance with regulatory standards is not maintained or if problems occur after the drug reaches the market.
Later discovery of previously unknown problems with a drug may result in restrictions on the drug or even complete withdrawal of
the drug from the market. After approval, some types of changes to the approved drug, such as adding new indications, certain manufacturing
changes and additional labeling claims, are subject to further FDA review and approval. Manufacturers and other entities involved
in the manufacture and distribution of approved drugs are required to register their establishments with the FDA and certain state
agencies and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP regulations
and other laws and regulations.
21
Any drug product manufactured or distributed
by us pursuant to FDA approval will be subject to continuing regulation by the FDA, including, among other things, record-keeping
requirements, reporting of adverse experiences with the drug, providing the FDA with updated safety and efficacy information, drug
sampling and distribution requirements, complying with certain electronic records and signature requirements, and complying with
FDA promotion and advertising requirements. FDA strictly regulates labeling, advertising, promotion and other types of information
regarding approved drugs that are placed on the market, and imposes requirements and restrictions on drug manufacturers, such as
those related to direct-to-consumer advertising, the prohibition on promoting products for uses or in patient populations that
are not described in the product’s approved labeling (known as “off-label use”), industry-sponsored scientific
and educational activities, and promotional activities involving the internet. Discovery of previously unknown problems or the
failure to comply with the applicable regulatory requirements may result in restrictions on the marketing of a product for a certain
indication or withdrawal of the product from the market as well as possible civil or criminal sanctions. Failure to comply with
the applicable governmental requirements at any time during the product development process, approval process or after approval,
may subject an applicant or manufacturer to administrative or judicial civil or criminal sanctions and adverse publicity. The FDA
sanctions could include refusal to approve pending applications, withdrawal of an approval, clinical holds on post-marketing clinical
trials, enforcement letters, import refusals, product recalls, product seizures, total or partial suspension of production or distribution,
injunctions, fines, refusals of government contracts, mandated corrective advertising or communications with doctors, debarment,
restitution, disgorgement of profits, or civil or criminal penalties.
Expedited development and review programs
The FDA has a fast track designation program
that is intended to expedite or facilitate the process for reviewing new drug products that meet certain criteria. Specifically,
new drugs are eligible for fast track designation if they are intended to treat a serious or life-threatening disease or condition
and demonstrate the potential to address unmet medical needs for the disease or condition. With regard to a fast track product,
the FDA may consider for review sections of the NDA on a rolling basis before the complete application is submitted, if the sponsor
provides a schedule for the submission of the sections of the NDA, the FDA agrees to accept sections of the NDA and determines
that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the NDA.
Any product submitted to the FDA for approval,
including a product with a fast track designation, may also be eligible for other types of FDA programs intended to expedite development
and review, such as priority review and accelerated approval.
A product is eligible for priority review if
it is intended to treat a serious condition, and if approved, would provide a significant improvement in safety or efficacy compared
to currently marketed products. The FDA will attempt to direct additional resources to the evaluation of an application for a new
drug designated for priority review in an effort to facilitate the review. The FDA endeavors to review applications with priority
review designations within six months of the filing date, as compared to ten months for review of NDAs under its current PDUFA
review goals.
In addition, a product may be eligible for
accelerated approval. Drugs intended to treat serious or life-threatening diseases or conditions may be eligible for accelerated
approval upon a determination that the product has an effect on a surrogate endpoint that is reasonably likely to predict a clinical
benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, 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. As a condition of approval, the FDA may
require that a sponsor of a drug receiving accelerated approval perform adequate and well-controlled post-marketing clinical trials.
Drugs receiving accelerated approval may be subject to expedited withdrawal procedures if the sponsor fails to conduct the required
post-marketing trials or if such trials fail to verify the predicted clinical benefit. In addition, the FDA currently requires
as a condition for accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the commercial
launch of the product.
22
The Food and Drug Administration Safety and
Innovation Act (“FDASIA”) established a category of drugs referred to as “breakthrough therapies” that
may be eligible to receive breakthrough therapy designation. A sponsor may seek FDA designation of a compound as a “breakthrough
therapy” if the product is intended, alone or in combination with one or more other products, 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. The designation includes all of the fast track program features, as well as more intensive FDA interaction and guidance.
The breakthrough therapy designation is a distinct status from both accelerated approval and priority review, which can also be
granted to the same drug if relevant criteria are met. If a product is designated as breakthrough therapy, the FDA will work to
expedite the development and review of such drug.
Fast track designation, priority review and
breakthrough therapy designation do not change the standards for approval but may expedite the development or approval process.
However, even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets
the conditions for qualification or decide that the time period for FDA review or approval will not be shortened.
Orphan drug designation
Under the Orphan Drug Act, the FDA may grant
orphan designation to a drug intended to treat a rare disease or condition, which is a disease or condition that affects fewer
than 200,000 individuals in the United States or, if it affects more than 200,000 individuals in the United States, there is no
reasonable expectation that the cost of developing and making a drug product available in the United States for this type of disease
or condition will be recovered from sales of the product. Orphan designation must be requested before an NDA is submitted. After
the FDA grants orphan designation, the identity of the therapeutic agent and its potential orphan use are publicly disclosed by
the FDA. Orphan designation does not convey any advantage in or shorten the duration of the regulatory review and approval process.
If a product that has orphan designation subsequently
receives the first FDA approval for the disease or condition for which it has such designation, the product is entitled to orphan
product exclusivity, which means that the FDA may not approve any other applications to market the same drug for the same indication
for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan exclusivity
or inability to manufacture the product in sufficient quantities. The designation of such drug also entitles a party to financial
incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user-fee waivers. However,
competitors may receive approval of different products for the indication for which the orphan product has exclusivity or obtain
approval for the same product but for a different indication for which the orphan product has exclusivity. Orphan exclusivity also
could block the approval of one of our compounds for seven years if our compound is determined to be contained within the competitor’s
product for the same indication or disease, or if a competitor obtains approval of the same drug as defined by the FDA. In addition,
if an orphan designated product receives marketing approval for an indication broader than what is designated, it may not be entitled
to orphan exclusivity.
Abbreviated New Drug Applications, 505(b)(2)
Applications, and Marketing exclusivity
In seeking approval for a drug through an NDA,
applicants are required to list with the FDA each patent with claims that cover the applicant’s drug or an approved method
of use of the drug. Upon approval of a drug, each of the patents listed in the application for the drug is then published in the
FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the “Orange Book.” Drugs
listed in the Orange Book can, in turn, be cited by competitors in support of approval of an Abbreviated New Drug Application,
or ANDA, or a 505(b)(2) application. In this case, the original NDA (the so-called pioneer drug) is known as the
“listed” drug or “reference-listed” drug. An ANDA provides for marketing of a drug that has the same active
ingredient and the same strength, route of administration and dosage form as the listed drug and has been shown through testing
to be bioequivalent to the listed drug or receives a waiver from bioequivalence testing. ANDA applicants are generally not required
to conduct or submit results of preclinical or clinical tests to prove the safety or effectiveness of their drug, other than the
requirement for bioequivalence testing. Drugs approved in this way are considered therapeutically equivalent, and are commonly
referred to as “generic equivalents” to the listed drug. These drugs then generally can be substituted by pharmacists
under prescriptions written for the original listed drug.
23
A 505(b)(2) application is a type of NDA that
relies, in part, upon data the applicant does not own and to which it does not have a right of reference. Such applications often
are submitted for changes to previously approved drug products, and rely on the FDA’s prior findings of safety and effectiveness
for a third party’s NDA to abbreviate the showings the sponsor of the 505(b)(2) application must make to establish that its
product is safe and effective.
The ANDA or 505(b)(2) applicant is required
to certify to FDA concerning any patents listed for the referenced approved drug in FDA’s Orange Book. Specifically, for
each listed patent, the applicant must certify that: (1) the required patent information has not been filed; (2) the
listed patent has expired; (3) the listed patent has not expired but will expire on a particular date and approval is sought
after patent expiration; or (4) the listed patent is invalid, unenforceable or will not be infringed by the new drug. A certification
that the new drug will not infringe the already approved drug’s listed patents or that such patents are invalid or unenforceable
is called a Paragraph IV certification. If the ANDA or 505(b)(2) applicant does not include a Paragraph IV certification,
the ANDA or 505(b)(2) application will not be approved until all of the listed patents claiming the referenced drug have expired,
except for any listed patents that only apply to uses of the drug not being sought by the ANDA or 505(b)(2) applicant.
If the ANDA or 505(b)(2) applicant has
made a Paragraph IV certification, the applicant must also send notice of a Paragraph IV Notice Letter to the NDA and patent holders
once the ANDA or 505(b)(2) application 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 Notice Letter. The filing of a patent infringement lawsuit
within 45 days of the receipt of notice of a Paragraph IV Notice Letter automatically prevents FDA from approving the ANDA
until the earlier of 30 months, expiration of the patent, settlement of the lawsuit, modification by a court or a decision
in the infringement case that is favorable to the ANDA or 505(b)(2) applicant. As discussed below, the ANDA or 505(b)(2) application
also will not be approved until any applicable non-patent exclusivity listed in the Orange Book for the reference-listed
drug has expired.
Market exclusivity provisions under the FDCA
can delay the submission or approval of certain marketing applications. The FDCA provides a five-year period of non-patent marketing
exclusivity within the United States to the first applicant to obtain approval of an NDA for a new chemical entity. A drug is a
new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule
or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not approve or even accept
for review an abbreviated new drug application (“ANDA”), or an NDA submitted under Section 505(b)(2) (a “505(b)(2)
NDA”), submitted by another company for another drug containing the same active moiety, regardless of whether the drug is
intended for the same indication as the original innovative drug or for another indication, where the applicant does not own or
have a legal right of reference to all the data required for approval. However, an application may be submitted after four years
if it contains a certification of patent invalidity or non-infringement to one of the patents listed with the FDA by the innovator
NDA holder.
The FDCA alternatively provides three years
of marketing exclusivity for an NDA, or supplement to an existing NDA, if new clinical investigations, other than bioavailability
studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application,
for example new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the modification
for which the drug received approval on the basis of the new clinical investigations and does not prohibit the FDA from approving
ANDAs or 505(b)(2) NDAs for drugs containing the active ingredient for the original indication or condition of use. Five-year and
three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would
be required to conduct or obtain a right of reference to all of the preclinical studies and adequate and well-controlled clinical
trials necessary to demonstrate safety and effectiveness.
24
Pediatric exclusivity is another type of marketing
exclusivity available in the United States. Pediatric exclusivity provides for an additional six months of marketing exclusivity
attached to another period of exclusivity if a sponsor conducts clinical trials in children in response to a written request from
the FDA. The issuance of a written request does not require the sponsor to undertake the described clinical trials. In addition,
orphan drug exclusivity, as described above, may offer a seven-year period of marketing exclusivity, except in certain circumstances.
United States Patent Term Restoration
Depending upon the timing, duration and specifics
of FDA approval of our future product candidates, some of our United States patents may be eligible for limited patent term extension
under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred to as the Hatch-Waxman Amendments.
The Hatch-Waxman Amendments permit restoration of the patent term of up to five years as compensation for patent term lost during
the FDA regulatory review process for a drug that has not been previously approved for commercial marketing. Patent-term restoration,
however, cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date and only
those claims covering such approved drug product, a method for using it or a method for manufacturing it may be extended. The patent-term
restoration period is generally one-half the time between the effective date of an IND and the submission date of an
NDA plus the time between the submission date of an NDA and the approval of that application, except that the review period is
reduced by any time during which the applicant failed to exercise due diligence. Only one patent applicable to an approved drug
is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent. The
U.S. Patent and Trademark Office, in consultation with the FDA, reviews and approves the application for any patent term extension
or restoration. In the future, we may apply for restoration of patent term for our currently owned or licensed patents to add patent
life beyond its current expiration date, depending on the expected length of the clinical trials and other factors involved in
the filing of the relevant NDA.
Foreign Sales
Sales outside the United States of potential
drug compounds we develop will also be subject to foreign regulatory requirements governing human clinical trials and marketing
for drugs. The requirements vary widely from country to country, but typically the registration and approval process takes several
years and requires significant resources. In most cases, if the FDA has not approved a potential drug compound for sale in the
United States, the potential drug compound may be exported for sale outside of the United States, only if it has been approved
in any one of the following: the European Union or a country in the European Economic Area (the countries in the European Union
and the European Free Trade Association) if the drug or device is marketed in that country or the drug or device is authorized
for general marketing in the European Economic Area, Canada, Australia, New Zealand, Japan, Israel, Switzerland and South Africa.
There are specific FDA regulations that govern this process.
U.S. coverage and reimbursement
Significant uncertainty exists as to
the coverage and reimbursement status of any compound for which we may seek regulatory approval. Sales in the United States will
depend in part on the availability of sufficient coverage and adequate reimbursement from third-party payors, which include government
health programs such as Medicare, Medicaid, CHIP, TRICARE and the Veterans Administration, as well as managed care organizations
and private health insurers. Prices at which we or our customers seek reimbursement for our therapeutic compounds can be subject
to challenge, reduction or denial by payors.
25
The process for determining whether
a payor will provide coverage for a product is typically separate from the process for setting the reimbursement rate that the
payor will pay for the product. A payor’s decision to provide coverage for a product does not imply that an adequate reimbursement
rate will be available. Additionally, in the United States there is no uniform policy among payors for coverage or reimbursement.
Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own coverage and reimbursement
policies, but also have their own methods and approval processes. Therefore, coverage and reimbursement for products can differ
significantly from payor to payor. If coverage and adequate reimbursement are not available, or are available only at limited levels,
successful commercialization of, and obtaining a satisfactory financial return on, any product we develop may not be possible.
Third-party payors are increasingly challenging
the price and examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety
and efficacy. In order to obtain coverage and reimbursement for any product that might be approved for marketing, we may need to
conduct expensive studies in order to demonstrate the medical necessity and cost-effectiveness of any products, which would be
in addition to the costs expended to obtain regulatory approvals. Third-party payors may not consider our compounds to be medically
necessary or cost-effective compared to other available therapies, or the rebate percentages required to secure favorable coverage
may not yield an adequate margin over cost or may not enable us to maintain price levels sufficient to realize an appropriate return
on our investment in drug development. Additionally,
we or our collaborators may develop companion diagnostic tests for use with our product candidates. Companion diagnostic tests
require coverage and reimbursement separate and apart from the coverage and reimbursement for their companion pharmaceutical or
biological products. Similar challenges to obtaining coverage and reimbursement, applicable to pharmaceutical or biological products,
will apply to companion diagnostics.
Fraud and Abuse Laws
Federal and state health care laws and
regulations restrict business practices in the biopharmaceutical industry. In the biopharmaceutical industry, there are a number
of federal and state health care regulatory requirements that apply to entities, including, but not limited to, the federal and
state fraud and abuse laws. These laws include, but are not limited to, anti-kickback and self-referral law, civil false claims
act law, criminal false statement law, civil monetary penalty laws, exclusion law, and other civil, criminal, and administrative
laws. Health care laws, regulations, and guidance continuously evolve and are thereby subject to constant change.
The Federal Anti-Kickback Statute, 42
U.S.C. § 1320a-7b(b), among other things, prohibits the knowing and willful offer, payment, solicitation or receipt of any
form of remuneration, whether directly or indirectly and overtly or covertly in cash or in kind, in return for, or to induce the
referral of an individual for the:
●
furnishing or arranging for the furnishing of items or services reimbursable in whole or in part under Medicare, Medicaid or other federal healthcare programs; or
●
purchase, lease, or order of, or the arrangement or recommendation of the purchasing, leasing, or ordering of any item or service reimbursable in whole or in part under Medicare, Medicaid or other federal healthcare programs.
There are a number of narrow safe harbors
to the Federal Anti-Kickback Statute. Such safe harbors permit certain payments and business practices that, although they would
otherwise potentially implicate the Federal Anti-Kickback Statute, are not treated as an offense under the same if all of the requirements
of the specific applicable safe harbor are met. Actual knowledge of the statute or specific intent to violate it is not required
in order for a person or entity to have committed a violation.
The Federal Anti-Kickback Statute applies
to certain arrangements with healthcare providers, product end users and other parties, including marketing arrangements and discounts
and other financial incentives offered in connection with the sales of our products. Regulatory authorities may determine that
certain marketing, pricing, or other activities violate the Federal Anti-Kickback Statute or other applicable laws. Noncompliance
with the Federal Anti-Kickback Statute can result in civil, administrative and/or criminal penalties, restrictions on the ability
to operate in certain jurisdictions, and exclusion from participation in Medicare, Medicaid or other federal healthcare programs.
In addition, non-compliance can result in the need to curtail and/or restructure operations. Any penalties, damages, fines, exclusions,
curtailment or restructuring of operations could adversely affect the ability to operate a business, financial condition, and results
of operations. A violation of the Federal Anti-Kickback Statute can serve as a false or fraudulent claim for purposes of the civil
False Claims Act and the civil monetary penalties statute.
26
The federal Health Insurance Portability and Accountability
Act of 1996 (“HIPAA”) among other things, enacted numerous provisions that prohibit knowingly and willfully executing, or
attempting to execute, a scheme or artifice to defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses,
representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program,
regardless of the payor (e.g., public or private), willfully obstructing a criminal investigation of a healthcare offense, and knowingly
and willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially false, fictitious
or fraudulent statements in connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare
matters. These provisions include 18 U.S.C. §§ 286, 287, 669, 1035, 1347, and 1518, all as described further below.
The Ethics in Patient Referrals Act,
commonly known as the “Stark Law,” 42 U.S.C. § 1395nn, prohibits a physician from making referrals for certain
“designated health services” payable by Medicare to an entity in which the physician or an immediate family member
of such physician has an ownership or investment interest or with which the physician has entered into a compensation arrangement,
unless a statutory exception applies. There are a number of exceptions to the Stark Law. Such exceptions permit certain payments
and arrangements that, although they would otherwise potentially implicate the Stark Law, are not treated as a violation under
the same if the requirements of the specific exceptions are met. Violation of the Stark Law could result in denial of payment,
disgorgement of reimbursements received under a noncompliance arrangement, civil penalties, damages and exclusion from Medicare
or other governmental programs. These requirements are highly technical and there can be no guarantee that regulatory authorities
will not determine or assert that arrangements are in violation of the Stark Law and do not otherwise meet applicable Stark Law
exceptions.
The federal false statements statute,
42 U.S.C. § 1320a-7b(a), prohibits knowingly and willfully falsifying, concealing, or omitting a material fact or making any
materially false statement in connection with the delivery of health care benefits, items, or services. Similarly, 18 U.S.C. §
1035 prohibits a person or entity, in any matter involving a health care benefit program, from knowingly or willfully falsifying,
concealing, or covering up by any trick, scheme, or device a material fact; making any materially false, fictitious, or fraudulent
statements or representations; or making or using any materially false writing or document knowing the same to contain any materially
false, fictitious, or fraudulent statement or entry. In addition to criminal penalties, violation of these statutes may result
in collateral administrative sanctions, including exclusion from participation in Medicare, Medicaid and other federal health care
programs.
18 U.S.C. § 669 prohibits knowingly
and willfully embezzling, stealing, or otherwise without authority converting to the use of any person or entity other than the
rightful owner, or intentionally misapplying any of the moneys, funds, securities, premiums, credits, property, or other assets
of a health care benefit program. In addition to criminal penalties, violation of this statute may result in collateral administrative
sanctions, including exclusion from participation in Medicare, Medicaid and other federal health care programs.
The criminal health care fraud statute,
18 U.S.C. § 1347, establishes criminal liability for whoever knowingly and willfully executes, or attempts to execute, a scheme
or artifice to defraud any health care benefit program, or to obtain, by means of false or fraudulent pretenses, representations,
or promises, any of the money or property owned by, or under the custody or control of, any health care benefit program, in connection
with the delivery of or payment for health care benefits, items, or services. In addition to criminal penalties, violation of this
statute may result in collateral administrative sanctions, including exclusion from participation in Medicare, Medicaid and other
federal health care programs. A person or entity need not have actual knowledge of this law or specific intent to commit a violation
of this law.
18 U.S.C. § 1518 establishes criminal
liability for whoever willfully prevents, obstructs, misleads, delays or attempts to prevent, obstruct, mislead, or delay the communication
of information or records relating to a violation of a Federal health care offense to a criminal investigator. In addition to criminal
penalties, violation of this statute may result in collateral administrative sanctions, including exclusion from participation
in Medicare, Medicaid and other federal health care programs.
18 U.S.C. § 286 establishes criminal
liability for whoever enters into any agreement, combination, or conspiracy to defraud the United States, or any department or
agency thereof, by obtaining or aiding to obtain the payment or allowance of any false, fictitious or fraudulent claim. In addition
to criminal penalties, violation of this statute may result in collateral administrative sanctions, including exclusion from participation
in Medicare, Medicaid and other federal health care programs.
27
18 U.S.C. § 287 establishes criminal
liability for whoever knowingly makes or presents a false, fictitious or fraudulent claim to the United States Government, including
any department or agency thereof. In addition to criminal penalties, violation of this statute may result in collateral administrative
sanctions, including exclusion from participation in Medicare, Medicaid and other federal health care programs.
The Federal False Claims Act, 31 U.S.C.
§ 3729, et seq., provides, in part, that the federal government—or a private party on behalf of the government—may
bring a lawsuit against any person whom it believes has knowingly presented, or caused to be presented, a false or fraudulent claim
for payment, or who has made a false statement or used a false record to get a claim paid or to avoid, decrease or conceal an obligation
to pay money to the federal government or who has knowingly retained an overpayment. Knowledge under the Federal False Claims Act
means actual knowledge, deliberate indifference, or reckless disregard. In addition, amendments in 1986 to the Federal False Claims
Act have made it easier for private parties to bring whistleblower lawsuits against companies.
The civil monetary penalties law, 42
U.S.C. § 1320a-7a, provides, in part, that the federal government may seek civil monetary penalties against any person who
presents or causes to be presented claims to a Federal health care program that the person knows or should know is for an item
or services that was not provided as claimed or is false or fraudulent, or the person has made a false statement or used a false
record to get a claim paid. The federal government may also seek civil monetary penalties for a wide variety of other conduct,
including offering remuneration to influence a Medicare or Medicaid beneficiary’s selection of providers and violations of
the Federal Anti-Kickback Statute.
Violations of the Federal False Claims
Act and/or the Civil Monetary Penalties Law can result in penalties ranging from $12,537 to $25,076 for each false claim violation
of the Federal False Claims Act and varying amounts based on the type of violation of the Civil Monetary Penalties Law, plus up
to three times the amount of damages that the federal government sustained. In addition, the federal government may also seek exclusion
from participation in all federal health care programs.
42 U.S.C. Section 1320a-7 provides that
individuals and entities can be mandatorily or permissively excluded from participation in federal health care programs. The grounds
for mandatory exclusion include, but are not limited to, conviction for a criminal offense related to the delivery of an item or
service reimbursed under a federal or state health care program, and a conviction related to health care fraud. The grounds for
permissive exclusion include, but are not limited to, criminal offenses relating to fraud inside and outside of health care, convictions
related to obstruction of an investigation or audit, and/or failure to disclose certain required information. Exclusion from federal
health care programs—whether mandatory or permissive—may mean that our customers may not be able to get reimbursed
by federal and/or state health care programs for use or dispensing of our products .
State Fraud and Abuse Provisions
Many states have also adopted some form
of anti-kickback and anti-referral laws and false claims acts and civil monetary penalties and other fraud and abuse provisions
that apply regardless of payer, in addition to items and services reimbursed under Medicaid and other state programs. A determination
of liability under such laws could result in fines, penalties, and exclusion, as well as restrictions on the ability to operate
in these jurisdictions.
Corporate liability can be present as
a result of the illegal activities of employees, representatives, contractors, collaborators, agents, subsidiaries, or affiliates,
even if they were not explicitly authorized. There can be no assurance that all employees, representatives, contractors, collaborators,
agents, subsidiaries or affiliates will comply with the foregoing laws at all times. Violation of the aforementioned and other
laws could result in whistleblower complaints, investigations, sanctions, settlements, prosecution, government oversight and reporting,
other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions
or other administrative remedies, suspension and/or debarment from contracting with certain governments or other persons, the loss
of privileges, reputational harm, contract damages, adverse media coverage and other collateral consequences. In addition, corporate
directors, officers, employees, and other representatives who engage in violations of these and other laws may face imprisonment,
fines, and penalties. If any subpoenas or investigations are launched, or governmental or other sanctions are imposed, or if a
company does not prevail in any possible civil or criminal litigation, business, financial condition, and results of operations
could be materially harmed. In addition, responding to any action will likely result in a materially significant diversion of management’s
attention and resources and significant defense costs and other professional fees. Enforcement actions and sanctions could further
harm business, financial condition, and results of operations. Any of the consequences contained in this paragraph and section
could adversely affect the ability to operate the business, financial condition, and the results of operations.
28
Sunshine Act
The
Sunshine Act requires manufacturers of products reimbursed by Medicare, Medicaid or the Children’s Health Insurance Program
(“CHIP”) to collect and annually report detailed data to the Centers for Medicare and Medicaid Services (“CMS”)
regarding payments or other transfers of value to physicians, certain other health care providers (such
as physicians assistants and nurse practitioners), and teaching hospitals (“covered recipients”), as well as
any ownership or investment interest held by physicians and their immediate family members. The reporting data must be accompanied
by an attestation as to the accuracy of the data and failure to timely and accurately submit required information may result in
civil monetary penalties.
Health Insurance Portability and
Accountability Act
Besides enacting the program integrity provisions described above, HIPAA, also
created a new set of privacy and security requirements. As amended by the Health Information Technology for Economic and Clinical Health
Act, and implementing regulations thereunder, HIPAA requires certain healthcare providers, health plans and healthcare clearinghouses
who conduct specified electronic healthcare transactions (“covered entities”), as well as their independent contractors and
agents who conduct certain activities involving protected health information on their behalf (“business associates”) to comply
with enumerated requirements relating to the privacy, security and transmission of protected health information. Failure to comply with
HIPAA can result in corrective action, as well as civil fines and penalties and government oversight. Among other changes, HITECH made
HIPAA security standards directly applicable to business associates, increased the tiered civil and criminal fines and penalties that
may be imposed against covered entities, business associates and possibly other persons, and gave state attorneys general new authority
to file actions to enforce HIPAA. Further, the breach notification rule implemented under HITECH requires covered entities to notify affected
individuals, the U.S. Department of Health and Human Services Office of Civil Rights (“OCR”), the agency that enforces HIPAA,
and for breaches affecting more than 500 individuals, the media, of any breaches of unsecured protected health information. HIPAA does
not create a private right of action for individuals, though individuals may submit complaints related to HIPAA to OCR.
Legislative Activities Aimed at Controlling
Drug Costs
In the United States, there have been, and continue to be proposed and enacted
legislation at the federal and state levels designed to, among other things, bring more transparency to drug pricing, review the relationship
between pricing and manufacturer patient programs, reduce the cost of drugs under Medicare, and reform government program reimbursement
methodologies for drugs. For example, in July 2021, the Biden administration released an executive order, “Promoting Competition
in the American Economy,” with multiple provisions aimed at prescription drugs. In response to Biden’s executive order, on
September 9, 2021, the U.S. Department of Health and Human Services (“HHS”) released a Comprehensive Plan for Addressing High
Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that Congress could
pursue as well as potential administrative actions HHS can take to advance these principles. In addition, the Inflation Reduction Act
(“IRA”) passed on August 16, 2022. The IRA, among other things, (1) directs HHS to negotiate the price of certain highly-utilized
single-source drugs and biologics covered under Medicare and (2) imposes rebates under Medicare Part B and Medicare Part D to penalize
price increases that outpace inflation. These provisions will take effect progressively starting in fiscal year 2023, although they may
be subject to legal challenges. It is currently unclear how the IRA will be implemented but is likely to have a significant impact on
the pharmaceutical industry. Further, the Biden administration released an additional executive order on October 14, 2022, directing HHS
to submit a report within 90 days on how the Center for Medicare and Medicaid Innovation can be further leveraged to test new models for
lowering drug costs for Medicare and Medicaid beneficiaries. We expect that additional U.S. federal healthcare reform measures will be
adopted in the future, any of which could limit the amounts that the U.S. federal government will pay for healthcare products and services,
which could result in reduced demand for our product candidates or additional pricing pressures.
