1. BUSINESS
Overview
We
are a clinical-stage specialty immunotherapy company harnessing one of nature’s most powerful immunological weapons, CD8+ cytotoxic
T lymphocytes (“CD8+ CTLs” or “CTLs”), to develop off-the-shelf, precision T cell therapies for the treatment
of infectious diseases, cancers, and neurological disorders, with the aim of addressing the significant unmet needs of large patient
populations. We believe that sustainability and commercial success in the forthcoming era of medicine will rely on ensuring patient accessibility
through advanced science, innovative business models and engagement across the development lifecycle and healthcare system. We aspire
to be the first biotechnology company offering commercially attractive, economically viable, and cost-effective personalized T cell therapies.
We
believe our allogeneic, precision T cell technology platform, ExacTcell TM , represents a significant scientific breakthrough
that has the potential to produce a new class of off-the-shelf – manufactured and stored for immediate use – drugs with diverse applications
spanning virology, oncology, and neurology. ExacTcell is a set of processes and methodologies to develop, enrich, and expand single human
leukocyte antigen (“HLA”) restricted CTL therapies with proactively selected, precisely defined targets. HLA molecules are
proteins that play an important role in the immune system’s ability to recognize “self” versus “foreign.”
There are numerous HLA types that vary from person to person. CD8+ CTLs, also known as killer T cells, are white blood cells that are
part of the immune system and destroy infected, malignant, or otherwise damaged cells. We are focused on using ExacTcell to develop allogeneic
therapeutics, meaning therapeutics that are intended to be infused in patients other than the original donor.
ExacTcell
therapies are based on carefully selected, naturally occurring CTLs that are designed to recognize targets of interest from the body’s
native T cell receptor pool, unlike genetically engineered T cell therapies. CD8+ CTLs in ExacTcell-based products target multiple and
distinct antigens, with the aim to circumvent the impact of mutations in viruses and cancer cells, which can render existing treatments
ineffective. ExacTcell is designed to maximize the immunologic specificity of our products in order to eliminate malignant and virally
infected cells while allowing healthy cells to remain intact. We believe this high degree of specificity has the potential to significantly
reduce the chances of cross-reactivity or adverse impact on healthy cells. Our confidence in ExacTcell is reflected in our development
pipeline, which has been carefully tailored to address the unmet needs of large patient populations grappling with life-threatening viral
diseases, both viral and non-viral induced cancers, and neurological disorders such as multiple sclerosis.
The
first clinical product of ExacTcell, TVGN 489, is being developed to fill a critical gap in COVID-19 therapeutics for the immunocompromised
and the high-risk elderly, with potential applications in both treatment and prevention of chronic lingering
symptoms of the disease (“Long COVID”). Viruses, including COVID-19, hijack cellular machinery to transform infected cells
into virus production plants. Elimination of infected cells is necessary to allow them to be replaced by healthy, uninfected counterparts.
TVGN 489 consists of CTLs that are designed to be active against multiple precise, well defined, and well characterized targets spread
across the SARS-CoV-2 genome. The product progressed from pre-discovery to the clinic in less than 18 months, and in January 2023, we
completed the Phase 1 proof-of-concept clinical trial of TVGN 489 for the treatment of ambulatory, high-risk adult COVID-19 patients.
No dose-limiting toxicities or significant treatment-related adverse events were observed in the treatment arm. Secondary endpoints showing
a rapid reduction of viral load and that infusion of TVGN 489 did not prevent development of the patients’ own T cell-related (cellular)
or antibody-related (humoral) anti-COVID-19 immunity were also met. None of the patients reported progression of infection, reinfection,
or the development of Long COVID during the six-month follow-up period. These clinical observations were mirrored by laboratory evidence
of the persistence of TVGN 489 cells for at least six months after treatment. We hope to launch a pivotal trial of TVGN 489 in COVID-19
patients with B cell malignancies as soon as late 2024, with studies of other highly vulnerable populations thereafter. TVGN 489 is also
in preclinical development for treatment and prevention of Long COVID.

Business
Combination
Prior
to February 14, 2024, Semper Paratus Acquisition Corporation (“Semper Paratus”) was a special purpose acquisition
company formed for the purpose of effecting a merger, stock purchase, reorganization or similar acquisition or business combination
with one or more businesses. On February 14, 2024 (the “Closing Date”), Semper Paratus completed the previously
announced business combination pursuant to that certain Agreement and Plan of Merger by and among Semper Paratus, Semper Merger Sub,
Inc., a Delaware corporation and a wholly owned subsidiary of Semper Paratus (“Merger Sub”), SSVK Associates, LLC,
Semper Paratus’s sponsor (the “Sponsor”), in its capacity as purchaser representative, Tevogen Bio Inc, a Delaware
corporation (“Tevogen Bio”), and Dr. Ryan Saadi, in his capacity as seller representative (the “Merger
Agreement”).
As
contemplated by the Merger Agreement, on the Closing Date, Merger Sub merged with and into Tevogen Bio, with Tevogen Bio being the surviving
company and a wholly owned subsidiary of Semper Paratus (the “Merger,” and together with the other transactions contemplated
by the Merger Agreement, the “Business Combination”). In connection with the closing of the Business Combination, we changed
our name from “Semper Paratus Acquisition Corporation” to “Tevogen Bio Holdings Inc.” As of the open of trading
on February 15, 2024, our common stock and public warrants began trading on The Nasdaq Stock Market LLC (“Nasdaq”) as “TVGN”
and “TVGNW,” respectively.
Our
Pipeline
We
are leveraging our understanding of immunotherapy and our ExacTcell platform to discover, validate, and build a proprietary pipeline
of T cell therapies with diverse targets in infectious disease, cancer, and neurological disorders. The figure below details our pipeline
of product candidates and their targets:
1
Phase
1 clinical trials are designed in part to generate proof of concept data and safety-related data on tolerability and side effects.
2
A
pivotal trial is a trial designed to generate data sufficient to support the filing of an application for regulatory approval. A
pivotal trial may not necessarily be denoted as a Phase 3 clinical trial, and instead may be a Phase 2 or Phase 2/3 clinical trial.
We believe that Phase 2, Phase 2/3, or Phase 3 clinical trials may serve as pivotal trials for TVGN 489.
3
Our
completed Phase 1 clinical trial of TVGN 489 was specifically conducted in ambulatory, high-risk adult patients with acute cases
of COVID-19.
4
We
believe that the data from our completed Phase 1 clinical trial should be sufficient to serve as the basis for one or more later
stage, potentially pivotal trials in acute COVID-19 patients with B-cell cancer immune suppression, other B cell immune suppressed
acute COVID-19 patients without a B cell cancer indication, and for Long COVID prevention and treatment. We cannot be certain whether
we will be permitted to move from a Phase 1 trial directly to a pivotal trial covering any specific target population until FDA reviews
and concurs with or rejects our proposed plans, and FDA may require us to conduct further trials to generate additional safety and
efficacy data prior to approval.
5
Data
collected in the completed Phase 1 trial of TVGN 489 includes and in all future trials of TVGN 489 is expected to include information
regarding the incidence of Long COVID in patients treated with TVGN 489 versus untreated patients or those treated with alternate
approaches.
8
Our
Strategy
Our
goal is to have a positive impact on patients’ health and treatment equity by developing and commercializing personalized cell
therapies to treat infectious disease, cancer, and neurological disease. Key elements of our strategy to advance toward this goal include
the following:
●
Advancing
the clinical development of TVGN 489 for the treatment of COVID-19 and Long COVID . We completed a Phase 1 proof-of-concept
trial of TVGN 489 for the treatment of high-risk ambulatory adult COVID-19 patients in January 2023 and hope to launch a pivotal
trial in COVID-19 patients with B cell malignancies as soon as late 2024. TVGN 489 is also in development for other highly vulnerable
COVID-19 patients and sufferers of Long COVID. We will undertake a Long COVID genetic predisposition trial early in the second quarter
of 2024 in part to generate information needed to expeditiously conduct a Long Covid treatment trial that we expect to be launched
in approximately the first quarter of 2025.
●
Leveraging
our ExacTcell platform to develop therapies for additional indications . In addition to TVGN 489, we are leveraging our ExacTcell
platform to advance product candidates in virology, oncology, and neurology. Preclinical investigation is underway with product candidates
for the treatment of Epstein-Barr virus-associated lymphomas, multiple sclerosis, and several other viral and cancer targets.
●
Developing
manufacturing capabilities, including through acquisitions . We will need to develop manufacturing capabilities for clinical
and, if approved, commercial supply of our cell therapy products. Our efforts to develop manufacturing capability are currently focused
on acquiring existing manufacturing facilities or constructing one or more new manufacturing facilities, including through collaboration
with a potential facility development partner, and we have identified a potential clinical manufacturing facility for use.
●
Forming
strategic alliances and collaborating with partners to augment our capabilities . We may pursue strategic alliances with other
biopharmaceutical companies with well-established presences in the specialties we aim to target for our indications. This may include
co-marketing, co-promotion, and co-development relationships, or a partnership with a diagnostics company to help improve availability
of rapid HLA testing. We also intend to explore options to work with partners to augment the study and treatment of patients and
the impact of our product candidates, including medical professionals, healthcare professional networks, pharmacy benefit managers,
insurance companies, and artificial intelligence companies.

Our
ExacTcell Platform
Our
ExacTcell platform and our therapies harness one of nature’s own approaches to eradicating cancer and other diseases: the cytotoxic
or killer T cell. We believe that our patented ExacTcell precision allogeneic T cell development platform has the potential to be a broadly
applicable approach for developing convenient and reasonably priced cellular immunotherapies for the treatment of acute viral infections,
long-term consequences of viral infections such as Long COVID, viral- and non-viral-induced cancers, and certain neurological disorders.
ExacTcell
focuses on the selection and expansion of naturally occurring, genetically unmodified CD8+ CTLs to target multiple, distinct, preselected
antigens present only on virus-infected or malignant cells and to kill those cells. We believe that by relying on CD8+ CTLs, ExacTcell
has the potential to produce an entirely new class of drugs that could present numerous benefits over existing platforms. In contrast
to other approaches, ExacTcell enables a single, specific HLA molecule to be targeted in a clinical product and the specific target peptides
to be known with certainty and precision. HLA molecules are proteins present on the cell surface that play an important role in the immune
system’s ability to recognize “self” versus “foreign.” Specifically, HLA molecules present foreign antigens
to T cells for eradication. There are numerous HLA types that vary from person to person.
Killer
T cells are white blood cells that play a vital role in the immune system’s defense against diseases, including viruses and cancer.
Most CTLs, including those developed with ExacTcell, express T cell receptors (“TCRs”), which are surface proteins that provide
each T cell with its unique immune specificity to recognize and react against specific foreign antigenic peptides of infected or malignant
cells. These foreign antigenic peptides are presented in conjunction with an HLA molecule. The CTLs destroy their infected or malignant
cell targets by inducing them to undergo apoptosis, or programmed cell death, by releasing cytolytic granules that produce pores in the
target cell’s membrane. CTLs also possess a protein that spans the entirety of the cell membrane, known as Cluster Differentiation
8 (which makes them CD8+), that aids in the reaction. CD8+ T cells work in conjunction with HLA-class I molecules, and CD4+ T cells work
in conjunction with HLA-class II molecules.
10
Currently
available cell-based immunotherapy approaches include genetically unmodified T cells applied to the treatment of viruses early after
transplant and genetically modified chimeric antigen receptor (“CAR”) T cells used to treat a selected subset of malignancies.
We believe that to date, cellular therapy has not been harnessed to its full potential for clinical application. We believe that our
proprietary approach will allow T cell products to be generated with a much higher target-specific CD8+ content and better-defined target
specificity than existing commercially available approaches. Contrasted with our approach, the genetically unmodified T cells used after
hematopoietic stem cell transplantation for the treatment of viral infections have used large viral proteins, pools of peptides, or infected
cells to stimulate CTLs. These broader targets may stimulate both CD4+ and CD8+ T cell responses, resulting in more heterogeneous T cell
products with little information regarding the specific peptide targets recognized by the T cells. By stimulating with only carefully
defined smaller peptides that are selected to bind to a single HLA-class I molecule, our approach elicits a high degree of target-specific
CD8+ responses, which we believe may result in improved outcomes as compared to these other approaches. Knowing the specific peptide
targets also allows rapid identification of the impact of mutations on our CTL products.
Due
to the targeted nature of the cells ExacTcell can produce, we also believe we may be able to avoid some of the unwanted corollary effects
observed in other T cell immunotherapies. For example, we believe products developed through ExacTcell could potentially avoid the high
incidence of adverse events, some life-threatening, such as cytokine release syndrome and neurotoxicity, that have been observed with
autologous and allogeneic CAR-T platforms. Autologous cell therapies are derived from a donor’s own cells, as contrasted with allogenic
therapies such as ours, where cells are from third party donors.
In
order to select candidate peptides for ExacTcell products, we rely on a combination of computer-facilitated prediction of the ability
of specific peptide candidates to bind to specific HLA molecules and published scientific research. Once candidates are selected, we
use tetramer staining to assess whether T cells recognize the target peptides and assess cytotoxicity against individual peptide-pulsed
and non-pulsed targets. This allows us to rapidly and proactively select multiple, precise, candidate T cell targets and then quickly
experimentally confirm them for use. Through our Tevogen.ai artificial intelligence initiative, we are exploring ways to deploy artificial
intelligence-powered target detection to further accelerate our product development pace, either internally or in collaboration with
leading entities in the field of artificial intelligence.
As
illustrated in the figure below, we begin the ExacTcell process by collecting cells from a healthy donor. T cells from the donor are
exposed to the preselected targeted peptides and through a repetitive process of selection and expansion. CD8+ CTLs specific for the
targeted, antigenic peptides become the major cellular component of the final product. The expansion of the antigen specific CTLs is
extensive enough to produce over 100, and up to hundreds, of doses from a single donor. Those doses can then be used to treat hundreds
of patients who share the same HLA type.
11
ExacTcell
stands in contrast with both autologous and allogeneic CAR-T platforms, which target antigens present on both healthy and diseased cells
and require genetic modification of the T cells. In autologous CAR-T approaches, the quantity and health of desired T cells in patient
blood samples used to manufacture the CAR-T product have been among the largest obstacles for T cell therapies to date. Much of this
is due to the chemotherapy treatments the patients have already received. Some existing CAR-T therapies may take weeks to manufacture,
may require patients to receive pre-infusion lymphodepleting ( i.e. , immunosuppressing) chemotherapy as part of a lengthy preparation
process, and be hospitalized in many cases during the CAR-T cell infusion or afterwards due to the frequency of side effects from the
therapy such as cytokine release syndrome. These treatments may also require lifelong monitoring for the development and treatment of
infections due to eradication of normal parts of the immune system along with the cancer.
More
recently, in November of 2023, FDA announced that it had “received reports of T-cell malignancies, including chimeric antigen receptor
positive lymphoma, in patients who received treatment with BCMA- or CD19-directed autologous CAR T cell immunotherapies.” These
secondary malignancies resulted in hospitalization and death in a small subset of patients. On January 19, 2024, FDA required a class-wide
black box warning be added to the label of these CAR T products regarding this risk. FDA also underscored that the benefits of CAR-T
therapies continue to outweigh their risks but recommended lifelong monitoring of this potential side effect. Currently approved autologous
CAR-T platforms utilize the patient’s own T cells to manufacture their products. These cells have previously been exposed to cancer
therapy and are genetically altered and subsequently expanded.
In
contrast, CTLs generated using the ExacTcell platform come from a healthy donor with a normal immune system. ExacTcell CTLs are not genetically
altered in the manufacturing process and although they expand during manufacture, this is the expected response of a T-lymphocyte when
encountering its target antigen. The genetic modifications necessary to make CAR-T cells, which may be associated with the recent reports
of T-cell malignancies, are not utilized in the manufacture of our products made on the ExacTcell platform. Moreover, secondary malignancies
have not been described in the unmodified T cell products given to hundreds of post-transplant patients. Although our ExacTcell products
are not designed to be genetically modified, they are still in the early stages of testing, and only limited human and laboratory study
data are available regarding the risk profiles of our products. Allogeneic CAR-T approaches are in early-stage development, but concerns
exist regarding side effects similar to autologous CAR-T, and additionally, the development of graft versus host disease with allogeneic
CAR-T products, both of which we believe will be of lower risk with our platform.
Hundreds
of doses per donor can be obtained using the ExacTcell approach, which is expected to facilitate off-the-shelf use and the ability to
administer doses within hours of diagnosis in the case of treatments against viruses where rapid therapeutic intervention is crucial.
Use of TVGN 489, for example, is expected to begin with a confirmatory COVID-19 test and rapid HLA typing for which results would be
available in six to eight hours, allowing selection of the proper product based on HLA type. After confirmation of HLA type, thawing
takes minutes, and cells are infused within ten minutes of thawing.
The
convenience of “off-the-shelf” – manufactured and stored for immediate use – therapy has the potential to offer timely and
cost-efficient therapeutics by potentially eliminating the need for specialized medical facilities, unlike existing platforms. By producing
products in which the active CD8+ T cell components are present at high concentrations, we believe relatively small volumes will be required,
allowing our therapies to be easily and promptly delivered in the ambulatory setting as a very brief intravenous administration such
as in a physician’s office.
12
We
are working to further advance ExacTcell with a new, proprietary T cell receptor-engineered process (“TCR-T”), which we believe
may substantially increase the number of doses that can be produced from a single donor. Available technology can be used to allow us
to interrogate over a thousand individual T cells to determine which one kills peptide-pulsed targets fastest or kills the most in a
given timeframe. This highest performing T cell can then be isolated, and its T cell receptor sequenced, allowing us to make an artificial
TCR gene that can be introduced into CD8+ T cells collected from healthy donors. We believe this could allow at least a several-fold
increase in the number of desired CTLs as compared to our current approach. We expect efforts to produce second generation products based
on this process may begin shortly after and if initial regulatory approval of the first-generation product is obtained.
Our
First Product Candidate
Our
first product candidate, TVGN 489, is an off-the-shelf, allogeneic cytotoxic CD8+ T cell therapy designed to fill a critical gap in COVID-19
therapeutic solutions for the immunocompromised and the high-risk elderly, with potential applications in both treatment and prevention
of Long COVID. Treatment for these groups represents an area of unmet or incompletely met need which we believe TVGN 489 can significantly
address. We rapidly progressed TVGN 489 from pre-discovery to the clinic in only 18 months. TVGN 489 cells are derived from healthy donors
who recovered from a prior COVID-19 infection, and TVGN 489 is active against multiple, precise targets spread across the SARS-CoV-2
genome.
In
January 2023, we completed a Phase 1 proof-of-concept trial of TVGN 489 for the treatment of ambulatory high-risk adult COVID-19 patients.
No dose-limiting toxicities or significant TVGN 489-related adverse events were observed in this trial at any of the four dosing levels
tested. Secondary endpoints showing a rapid reduction of COVID-19 viral load and to show that infusion of TVGN 489 did not prevent development
of the patient’s own T cell-related (cellular) and antibody-related (humoral) anti-COVID-19 immunity were also met. In addition,
none of the patients in the treatment arm reported progression of infection, reinfection, or the development of Long COVID during the
six-month follow-up period. The TVGN 489 in the Phase 1 trial was formulated to match patients expressing HLA-A*02:01, the most common
HLA type in the population.
We
believe TVGN 489 has the potential to be less susceptible to viral mutation than monoclonal antibodies, less susceptible to drug resistance
than antivirals, and to rapidly be able to overcome any increased immune evasion of current and emerging SARS-CoV-2 variants. We also
believe ExacTcell can enable us to deliver products faster, at a greater scale, and at lower cost than future competing cell therapies,
if any. Despite selection of T cell targets in 2020, the HLA-A*02:01 TVGN 489 product has maintained a high degree of activity through
the full range of studied delta and subsequent omicron variants. In contrast, most monoclonal antibodies were withdrawn from the market
for lack of efficacy related to the emergence of new variants, providing what we believe to be evidence of decreased susceptibility of
TVGN 489 to viral mutation. In addition, knowing the precise peptide targets of our therapy helps allow rapid assessment regarding their
preservation or loss as soon as new variants are sequenced. We check emerging COVID-19 variants against TVGN 489 targets on an ongoing
basis.
COVID-19
Background
COVID-19,
caused by the SARS-CoV-2 virus, has killed millions and infected hundreds of millions since its emergence in late 2019. Groups currently
most at risk for poor outcomes due to COVID-19 are immunocompromised individuals unable to mount an adequate immune response, such as
those with immune system cancers, immunodeficiency disorders, transplant recipients, patients with immune-mediated disorders requiring
immunosuppressive therapy, or high doses of corticosteroids, the elderly and the unvaccinated. For example, recent data shows that the
majority of COVID-19 deaths occur in people over the age of 65. The risk of severe illness from COVID-19 for an individual tends to escalate
with an increase in their number of underlying medical conditions. In addition to the acute impacts of infection, a significant portion
of those who have been infected by COVID-19 in the past develop more chronic and potentially debilitating symptoms afterwards, a condition
termed Long COVID. Of US adults, 17.6% had experienced symptoms of Long COVID, according to the Centers for Disease Control and Prevention’s
(“CDC’s”) household pulse survey taken from January 9 through February 5, 2024. As of October 2023, 5% of all adults
were still experiencing symptoms of Long COVID, according to a USA FACTS review of U.S. Census Bureau data. Despite the availability
of vaccines and emergence of initial therapeutics, significant gaps and shortcomings in treatment remain both for vulnerable patients
experiencing an acute infection and for Long Covid sufferers for whom there are no treatment options approved for the indication or its
underlying causes.
13
Like
other viruses that have RNA as their genetic material, SARS-CoV-2 is constantly evolving through random mutations. New mutations can
potentially increase or decrease infectiousness and virulence. In addition, mutations can increase the virus’ ability to evade
adaptive immune responses from past SARS-CoV-2 infection or vaccination. New variants of the SARS-CoV-2 virus continue to emerge, and
many people continue to be adversely affected by COVID-19, particularly those at the highest risk and sufferers of Long COVID. Moreover,
a growing body of scientific data suggests new immune-evasive variants are more likely to arise in immunocompromised patients because
they are less able to eradicate the virus. The longer duration of infection within the host affords the virus more opportunity to mutate
so as to evade the immune system.
As
of May 2023, about 103 million cumulative confirmed COVID-19 cases were reported in the United States alone. While there has been a decrease
in the number of confirmed and reported cases, this is a multifactorial issue due in part to a decrease in testing by younger or healthier
individuals, reliance on home tests, the results of which are often not reported, expiration of federal funding for testing, and the
CDC’s discontinuation of collection of testing data. However, a large number of Americans remain highly vulnerable to COVID-19
infection, including immunocompromised and elderly patients. For example, the rate of hospitalization in cancer patients with COVID-19
infection remains high, specifically for those under active chemotherapy or immunosuppression. There is therefore a high unmet need to
have an effective treatment available for these populations. Classic herd immunity leading to eradication of COVID-19 is unlikely, much
as is the case for influenza, respiratory syncytial virus (RSV), and other endemic respiratory viruses. This contrasts with smallpox,
for example, where both natural infection and vaccination eliminated virus transmission. SARS-CoV-2 infection and vaccination produce
a steadily waning natural and vaccine-induced immunity, respectively, but do not eliminate transmission. Although the number of daily
reported cases and deaths has declined, the emergence of more transmissible variants has led to spikes in cases and mortality, and variants
are expected to continue to evolve over time.
The
current COVID-19 landscape is also characterized by continued vaccine hesitancy among a significant portion of the population, unequal
access to vaccines and treatment, lack of response in some immunocompromised and other high-risk groups, and breakthrough cases among
the vaccinated due in part to increased immune evasion by current and emerging variants and the relatively short duration of protection
by booster shots. We expect these circumstances to continue, which could adversely impact long-term community-level protective immunity.
In addition, we believe that the expiration of the U.S. federal Public Health Emergency and U.S. government funding for COVID-19 testing,
and treatment could lead to higher pricing for diagnostics and therapeutics.
Only
two anti-viral agents, Nirmatrelvir/Ritonavir (Paxlovid) and Remdesivir, have been FDA-approved for the treatment of COVID-19. While
Paxlovid is indicated for treatment in individuals at high risk for viral progression, neither drug has been specifically authorized
for use in immunocompromised patients, creating a need for the development of novel therapies in this area. Both drugs also present challenges
for subsets of patients. Paxlovid is associated with many drug-drug interactions, resulting in the need to temporarily stop ongoing medications
or seek alternative therapy and thereby making it difficult for some patients to take. This is especially true for patients on multiple
medications, which is often true of high-risk patients requiring anti-COVID-19 treatment. Paxlovid is also known to be associated with
COVID-19 rebound, which has been calculated as high as 21% in ambulatory patients, according to a study published in the Annals of Internal
Medicine in November 2023. Although the rate of rebound in high-risk subgroups is less well-documented, we anticipate it may be as high
or higher in this group. Paxlovid also must be started within five days of symptom development to be effective. Remdesivir must be given
within seven days and is only available in intravenous form, requiring three daily infusions in a treatment center. Remdesivir has also
been associated with liver enzyme abnormalities and gastrointestinal side effects. Monoclonal antibodies to the viral spike protein were
introduced early in the pandemic for treatment of COVID-19, but typically have been rendered ineffective over time as the virus continues
to evolve. No therapies have been approved to treat the underlying causes of the symptoms of Long COVID, and significant research is
ongoing to determine why some patients fully recover while others develop long-term complications.

Key
Advantages of TVGN 489
Given
the ongoing spread of COVID-19 and its effects and continued gaps in treatment, there is a clear need for alternatives to current therapeutic
options for COVID-19. We believe TVGN 489 has been shown to be less susceptible to viral mutations than monoclonal antibodies and thus
able to overcome the increased immune evasion of current and emerging COVID-19 variants. We also believe TVGN 489 has the potential to
be less susceptible to drug resistance than antivirals. As contrasted with existing therapies, TVGN 489 is designed to recognize multiple
specific target peptides from distinct COVID-19 proteins, versus one or two targets typically derived only from the spike protein. Whereas
other viral therapies buy time for natural immunity to emerge and definitively control the virus, TVGN 489 provides natural immunity
directly and immediately to patients.
TVGN
489’s targets have also persisted in studied COVID-19 variants. We have observed TVGN 489’s targets to be generally retained,
in nearly all cases at greater than a 95% level of retention, in the genome of all of the isolates of SARS-CoV-2 variants that we have
studied to date. This is in significant contrast with the target loss of anti-spike monoclonal antibody therapies, which led to the withdrawal
of emergency use authorizations (“EUAs”) that had been granted during the now-expired COVID-19 National Public Health Emergency.
For example, the EUA for AbCellera Biologics’ and Eli Lilly’s bamlanivimab administered alone, which was granted in November
2020, was revoked in April 2021 due to a sustained increase in viral variants that were not sensitive to this product.
COVID-19
variants have demonstrated how this virus is able to escape our immune system through mutation. However, we believe our proprietary approach
to manufacturing TVGN 489 may allow us to monitor the sequences of emerging variants and, if necessary, to proactively adjust or fine
tune our products to ensure that they continue to recognize and treat current and future variants of this and other viruses. For example,
with our approach, if a product contains T cells that recognize and target seven different peptides and one is lost through mutation,
that peptide can be dropped from future product batches. Similarly, if the mutation generates a new peptide target, that target can be
added to future batches. However, making these types of changes to TVGN 489 may require additional regulatory approvals, and there is
no guarantee that we will receive such approvals.
TVGN
489 is also designed to be fast acting, as the cells are fully mature and crafted to be primed to act as soon as they find their way
to infected cells. All patients in the interventional arm of our Phase 1 clinical trial noted improved symptoms within two to three days,
which is shorter than the average noted by patients in the observational arm, and 83% of patients in the interventional arm had negative
nasal swab polymerase chain reaction tests within 14 days. The consistency of the resolution was suggestive of a treatment effect and
the observed period is in contrast to a range of up to 90 days in the general population. This observed consistency and rapidity of nasal
swab COVID-19 resolution was in a population where five individuals were on active immunosuppression for cancer and one for lupus at
the time of COVID-19 infection. Two patients on the trial went on to stem cell transplantation, an immunosuppressive procedure, within
a month of treatment. Neither experienced COVID-19 reactivation, which we believe further attests to the rapid acting nature of this
product. When immunocompromised patients get sick from COVID-19, their current treatment regimens for existing conditions are often stopped.
For oncology patients, this can be especially disruptive or even harmful. Given TVGN 489’s design and these results, we believe
TVGN 489 may allow immunocompromised patients to recover and be able to return to their pre-COVID-19 treatment regimen with minimal delays.
Production
of TVGN 489 and Mechanism of Action
TVGN
489 cells are sourced from healthy donors who have recovered from a previous COVID-19 infection. These donor cells are subsequently expanded
by 600-fold or more by restimulating them toward specific peptide targets. This is accomplished by exposing them to antigen-presenting
cells and selectively isolating the T cells that recognize the specific targets. TVGN 489 is formulated to precisely target multiple
peptide targets spread across the SARS-CoV-2 genome, rather than focusing solely on the mutation-susceptible spike protein, which is
the primary target of most vaccines and monoclonal antibodies. Upon completion of the manufacturing process, the cells are frozen and
stored for future intravenous infusion.
15
Administration
of TVGN 489 infuses the body with killer T cells that have been designed to attack COVID-19 infected cells. These highly purified, multi-target
CD8+ CTLs are intended to bind to and eliminate infected cells expressing the targeted peptides against which the CTLs were manufactured.
Peptides are presented in conjunction with the HLA molecule and the CTLs eradicate diseased cells expressing these viral or malignant
targets. To be clinically effective, a T cell therapy must be compatible with the patient’s specific HLA type. Therefore, a panel
of HLA-specific CTL products is necessary to broadly cover and treat the population. In our next clinical trial of TVGN 489, we expect
to treat patients with the six most common HLA types, which we believe would represent between 60% and 65% of the COVID-19 infected population.
We plan to continue expansion into additional HLA types until we are confident that between 90% and 95% of the population could be treated
based on our research.
We
believe that once bound to infected cells, TVGN 489 cells then destroy the infected cells through formation of an immunological synapse
between the killer cell and target and the release of cytotoxic granules from TVGN 489 into the target. These both produce pores in the
target cell’s membrane and also trigger a process known as apoptosis, or programmed cell death, which is built into all our cells.
Then, once the infected cells die, new, healthy cells are able to grow in their place.
Discovery
and Preclinical Data
Our
approach to identifying CTL targets starts with computer-based prediction and then tests candidate peptides functionally with T cells. We use a technique known as tetramer staining to assess whether T cells recognized these target peptides, assessed cytotoxicity against
individual peptide-pulsed and non-pulsed targets, and selected final peptides for use in TVGN 489 on that basis.
We
conducted multiple in-vitro studies of TVGN 489 in preparation for filing the investigational new drug application (“IND”)
with FDA and observed strong antiviral activity against SARS-CoV-2 in these laboratory studies. In preclinical studies, we observed that
TVGN 489 cells kill target cells that are exposed to SARS-CoV-2 peptides, but not cells that are not exposed to those peptides. This
is illustrated in the figure below, which shows the percentage of cells killed over a four-hour period when targets were pulsed with
the peptides and when they were not, with the x-axis showing the lysis rates based on the ratio of CTLs to target cells.
16
Identification
of appropriate COVID-19 peptide targets for additional HLA molecules remains ongoing, and we plan to continue this testing until we are
confident that between 90% and 95% of the COVID-19 infected population could be treated based on our research.
Clinical
Development for COVID-19 Patients
FDA
permitted our IND for TVGN 489 to proceed in May 2021, and we began enrolling patients in the Phase 1 proof-of-concept trial of TVGN
489 for the treatment of high-risk ambulatory adult COVID-19 patients in October 2021. Patients in the trial were newly diagnosed with
COVID-19 and were deemed to be at high risk for complications due to the presence of one or more underlying medical conditions defined
as high risk by the CDC, including among others cancer, hypertension, obesity, diabetes, cardiovascular disease, and old age. The trial,
which was conducted at Thomas Jefferson University Hospital in Philadelphia, was completed in January 2023.
The
trial included two arms, with 12 patients in the treatment, or interventional, arm and 18 patients in the observational arm. Assignment
to the interventional arm versus the observational arm was based on each patient’s HLA type. Patients expressing HLA-A*02:01, the
most common HLA type in the population, matched the CTLs and were enrolled in the interventional arm. Patients in the treatment arm had
been infected with either the delta variant or one of three omicron variants of COVID-19. Patients on the interventional arm had a higher
median number of comorbid conditions, a higher incidence of immune compromise, and a higher number of patients who were unvaccinated
or failed to respond to vaccination versus patients on the observational arm.
Each
patient in the treatment arm received a single intravenous infusion of TVGN 489 within four days of diagnosis. Analysis of COVID-19 viral
load showed that the patients were early in their COVID-19 disease course. Patients were treated with TVGN 489 at one of four dose levels:
1 x 10 5 /kg; 3 x 10 5 /kg; 1 x 10 6 /kg; or 3 x 10 6 /kg. These dose levels were chosen based on
data regarding antiviral T cell therapy in hematopoietic transplant patients involving the administration of similar cell numbers. Three
patients were enrolled at each dosing level with the option to enroll three more if a significant side effect was observed. Each dose
level concluded with three patients rather than six and the treatment arm concluded with a total of 12 patients rather than 24, primarily
due to the absence of appreciable toxicities across all dose levels. The comparative arm, which was designed to end enrollment when treatment
arm enrollment was completed, concluded with 18 patients, appreciably less than what would have occurred if the treatment group required
additional enrollment. Observational arm patients received standard of care treatment, including monoclonal antibodies. Interventional
arm patients were monitored in the hospital for four days before being discharged and then were observed daily at home for ten additional
days and again at the one, two, three, and six-month anniversary of the initial infusion. Observational arm patients were monitored at
home over the same interval.
The
primary endpoints of the trial, which were safety-related, were met. No dose-limiting toxicities or significant adverse events related
to TVGN 489, including acute infusion reactions, cytokine release syndrome, neurotoxicity, or instances of graft versus host disease,
were observed in any patient at any dose level of our Phase 1 trial of TVGN 489.
17
Secondary
endpoints showing a rapid reduction of COVID-19 viral load and showing that infusion of TVGN 489 did not prevent development of the patient’s
own T cell-related (cellular) and antibody-related (humoral) anti-COVID-19 immunity were also met. In other words, observations indicate
that TVGN 489 did not prevent the body from responding to the infection and generating its own CTLs and antibodies to COVID-19.
All
treatment arm patients reported returning to their baseline level of health without COVID-19 symptoms within 14 days of treatment. All
such patients also reported symptom improvement within two to three days of treatment, which corresponded with a decrease in the COVID-19
viral load on PCR testing in the majority of patients. None of the patients who participated in the trial reported progression of their
COVID-19 infection and none developed COVID-19 or Long COVID during the six-month follow-up period. These clinical observations were
mirrored by laboratory evidence of the persistence of infused TVGN 489 cells for at least six months after treatment.
Persistence
of infused therapeutic cells remains a significant issue in the T cell therapy space, leading to challenges in controlling viral infections,
preventing viral recurrence, and managing cancer relapse. The shorter the CTLs persist in the recipient, the less opportunity they have
to perform their intended therapeutic tasks. Genetic differences between donor and recipient in allogeneic cell products and new genes
introduced into autologous products can be recognized by the patient’s immune system, which can encourage elimination of the administered
cells. This is one of the reasons why lymphodepleting therapy is commonly administered prior to CAR-T treatments. Maximizing the percentage
of CTLs in the products is also useful as the CTLs may receive re-stimulation from the virus infecting the patient and have a better
ability to protect themselves against elimination by the patient’s immune system. Most studies of genetically unmodified CTLs have
suggested that they are eliminated within weeks, with three months, in highly immune-suppressed hematopoietic blood and marrow transplant
(“HSCT”) patients, being the longest that they typically are reported to persist. The highly immune-suppressed nature of
the HSCT patient group is thought to allow for longer than typical persistence.
In
our Phase 1 clinical trial for TVGN 489, following infusion, peripheral blood of five patients was collected at various timepoints throughout
the six-month follow-up period. These samples were sent to Adaptive Biotechnologies (“Adaptive”) to evaluate the persistence
of infused TVGN 489 in the patients following treatment, and Adaptive conducted analyses by sequencing protein chains of TCRs in the
samples. As seen in the figure below, Adaptive’s data showed persistence of T cells present in the TVGN 489 product but absent
from the recipients prior to administration of TVGN 489. This subset of CTLs was found in all samples tested, including at the final
study assessment at six months. The TCRs used to recognize TVGN 489’s peptides were also shown to be largely distinct from person
to person, making it highly unlikely that the cells from later timepoints derive from anything other than the product in these five different
patients. Taken together, we believe this data shows the persistence of TVGN 489 cells six months after administration.
18
TVGN
489 COVID-19 Reactive CD8+ T Cells Detected Throughout the Six-Month Follow Up Period
Expansion
and persistence of allogeneic T cells has been associated with disease control in many settings. Whether the prolonged persistence of
the CTLs used in this study is of benefit in the treatment of COVID-19, Long COVID, or alternate future viral or oncologic targets for
these CTLs merits further examination. However, the evidence of their prolonged persistence provides us with encouragement for future
applications of the ExacTcell platform, particularly in oncology.
We
believe based on precedential industry examples, including in areas with high unmet needs or strong early phase clinical trial results,
that we may be able to commence pivotal trials of TVGN 489 on the basis of the results of our completed Phase 1 trial. A pivotal trial
is a trial designed to generate data sufficient to support the filing of an application for regulatory approval. Although the clinical
trial process usually includes three phases, a pivotal trial may not necessarily be denoted as a Phase 3 clinical trial, and instead
may be a Phase 2 or Phase 2/3 clinical trial. As soon as late 2024, we hope to begin a pivotal trial of TVGN 489 for the treatment of
COVID-19 in select vulnerable populations with humoral immune suppression due to B cell malignancy or the treatment thereof. Patients
with hematological malignancies continue to experience higher rates of hospitalization and death as compared to the general population
and those with solid tumors. Increased mortality, hospitalization, and incidence of Long COVID are higher in patients with B cell malignancies
due to inadequate vaccination response and the immunosuppressive consequences of treatment received for B cell cancers. While the major
acute outcomes of patients with hematological malignancies and COVID-19 have improved with increasing experience, delays in cancer treatment
due to the infection are increasingly recognized as a long-term impact of COVID-19 in this population. Whereas treatment arm patients
in our Phase 1 proof-of-concept clinical trial all had a single HLA type, we expect to treat patients in this pivotal trial who have
any of the six most common HLA types, which we believe would represent between 60% and 65% of the population. The primary endpoint of
this trial is planned to be reduced risk of hospitalization, with secondary endpoints relating to pace of viral load reduction, duration
of hospitalization, intensive care unit admissions, hours on supplemental oxygen, mortality, COVID-19 recurrence, Long COVID diagnosis,
and interruption in cancer treatment associated with COVID-19. At this stage, however, we cannot be certain whether we will be permitted
to move from a Phase 1 trial directly to a pivotal trial until FDA reviews and concurs with or rejects our proposed plans, and FDA may
require us to conduct further trials to generate additional safety and efficacy data.
As
development of TVGN 489 continues, we may also seek FDA’s regenerative medicine advanced therapy (“RMAT”) designation
for TVGN 489, which as explained in “Regulatory Environment – Expedited Development and Review Programs” below, is intended
to facilitate efficient development and expedited review.
19
Other
Target Patient Populations and Indications for TVGN 489
Other
target patient populations for TVGN 489 that we are prioritizing include the treatment of COVID-19 in B cell immune suppressed acute
COVID-19 patients without a B cell cancer indication, elderly and infirm acute COVID-19 patients, and Long COVID sufferers. As noted
above, these patients are among those with the greatest need for effective treatment. We believe that the safety and the clinical benefit
data from our completed Phase 1 clinical trial in ambulatory, high-risk adult patients should be sufficient to serve as the basis for
later-stage and potentially pivotal trials in these patient groups as well as for the prevention of Long COVID. However, whether such
trials may serve as pivotal trials, the phase of these trials, and the dose level to be selected in each trial remains subject to discussions
with and agreement by FDA.
We
also intend to develop TVGN 489 for the treatment of acute COVID-19 in patients on T cell suppressing drugs, including solid organ transplant
patients. The suppression of these patients’ immune systems may make them more susceptible to developing graft versus host disease.
Based on data analyzed from hundreds of bone marrow transplant patients receiving T cell therapies showing almost no incidence of graft
versus host disease, we believe it unlikely that patients on T cell suppressing drugs would develop graft versus host disease as a result
of treatment with TVGN 489. However, we believe the possibility nonetheless merits an additional safety study in this target population
prior to moving forward with later stage clinical development. In addition, higher doses may also be required for efficacy in these patients
as compared to other patients, as T cell suppressing drugs may reduce the impact of TVGN 489, requiring more cells to produce comparable
effect.
Recent
studies have detected persistent viral spike and nucleocapsid proteins in some Long COVID patients, suggesting a persistent viral reservoir
in those patients. If that is correct, we believe that TVGN 489 may circumvent Long COVID by preventing such a reservoir from being established
or by minimizing its size. No treated patients in our Phase 1 proof-of-concept trial developed Long COVID. We expect considerable additional
information on Long COVID prevention to be obtained from our planned acute COVID-19 treatment trials in which patients treated with TVGN
489 are expected to be compared to patients receiving standard of care treatment. We believe that the comparative data with respect to
patients in these trial arms going on to develop Long COVID should provide sufficient information to obviate a separate Phase 1 Long
COVID prevention trial, and that the significant unmet need for treatment in vulnerable patients as well as the efficacy data in preventing
Long COVID generated in these studies will lend further support for a streamlined development pathway. However, we cannot be certain
whether FDA will require us to conduct a separate prevention trial until FDA reviews and concurs with or rejects our proposed plans.
Work
is also beginning to identify Long COVID biomarkers in preparation for Long COVID treatment trials. We believe that certain individuals
may be genetically predisposed to Long COVID, in that the HLA types of Long COVID patients may be skewed toward some HLA types and away
from others. However, very limited Long COVID-related HLA typing information has been published to date. We therefore plan to launch
a non-therapeutic blood draw study in the second quarter of 2024 to assess whether the Long COVID population generally reflects
or is skewed towards or away from certain HLA types and to determine the optimal HLA types to target in a therapeutic trial of TVGN 489
for the treatment of Long COVID. This will allow us to develop CTLs for the HLA types most commonly found in Long COVID. Following the
results of that study, we plan to begin a clinical trial in Long COVID treatment in approximately the fourth quarter of 2024. Specific
symptoms will also be explored for an association with the viral reservoir in advance of this trial. Additional studies in vulnerable
populations are expected to follow.
20
Other
Discovery Programs, Product Candidates and Indications
In
addition to TVGN 489, we have several product candidates under early-stage development in virology, neurology, and oncology using our
ExacTcell platform technology. We are developing Epstein-Barr virus (“EBV”) specific CTLs for potential use in multiple sclerosis
(“MS”) and EBV-associated lymphomas. Our TVGN 601 is being developed for MS, and our TVGN 930 is being developed for EBV-associated
lymphomas. EBV is a common virus that infects over 90% of the world’s adult population, according to the World Health Organization
(the “WHO”), and is mainly transmitted through saliva, but also through other body fluids such as blood and semen. EBV is
the leading cause of infectious mononucleosis, and infects B-cells, a type of immune cell. Recent studies have suggested a potential
link between infection with EBV and later onset of inflammation that causes MS, and EBV infection can lead to a variety of cancers and
cancer-like disorders, including lymphomas, nasopharyngeal cancers, Post-Transplant Lymphoproliferative Disorder, and others. Given the
widespread nature of EBV and the serious health problems it can cause, investigative work is underway to identify effective peptide targets
for this virus to further the development of TVGN 601 and TVGN 930. Investigative work is also underway to develop product candidates
targeted at human papilloma virus (“HPV”)-related diseases, including TVGN 920 in cervical cancer and TVGN 960 in oropharyngeal
cancer, which is a type of mouth and throat cancer. Cervical cancer and oropharyngeal cancer are both commonly caused by HPV. According
to the WHO, HPV is responsible for 99% of cervical cancers. Mouth and throat cancers are more diverse, but the WHO estimates that about
70% of oropharyngeal cancers are due to HPV. Although a vaccine for HPV exists, the National Cancer Institute estimates that as of 2021,
only 58.5% of adolescents between the ages of 13 and 15 had received the recommended doses, estimated vaccination among older populations
is lower, and the COVID pandemic has shown that significant portions of the population will avoid vaccination. We believe that as with
other viral infections, the availability of both a preventative strategy and a treatment strategy is important to reduce incidence and
impact of disease and is investigating peptide candidates for HPV to further the development of TVGN 920 and TVGN 960.
We
believe that our ExacTcell approach also presents a novel and highly specific technique to combating cancers with T cell therapy. Unlike
CAR-T or Bispecific T-cell Engager (BiTE) antibody approaches, which recruit a heterogeneous group of T cells to the tumor, our approach
would instead focus a highly purified population of CTLs on the tumor, which we believe may provide more potential to accomplish the
task of eradicating the cancer. Cancer cells may not always express an ideal T cell target on their own. However, it is possible to coat
a cancer cell with a well-recognized target peptide using monoclonal antibodies or liposomes. We believe this would allow our target
specific CTLs to then attack the cancer cells. We also believe that our approach has the potential to eventually bring the benefits of
cell therapies to first-line options in oncology, as well as to create products that may overcome current limitations of checkpoint inhibitors.
T
cells can lose their ability to fight viruses and tumors in prolonged infections and cancer in a state called T cell exhaustion that
is characterized by the presence of certain biomarkers. Expression of these markers, which include PD-1, PDL-1, and LAG-3, has been observed
to be low level to absent in TVGN 489 cells. Moreover, TVGN 489 cells are functionally tested after generation, and have been observed
to remain strongly cytolytic at very low ratios of CTLs to target cells, which shows that they are not displaying the functional limitations
associated with T cell exhaustion.
Manufacturing
We
relied on a Clinical Trial Services and Materials Agreement with Thomas Jefferson University for the manufacture of TVGN 489 for our
Phase 1 proof-of-concept trial. However, we will need to develop manufacturing capabilities for clinical and, if approved, commercial
supply of our cell therapy products. Our efforts to develop manufacturing capability are currently focused on acquiring existing manufacturing
facilities or constructing one or more new manufacturing facilities, including through collaboration with a potential facility development
partner.
Our
Commercialization Plans
If
approved, we plan to globally commercialize TVGN 489 and our other product candidates aimed at serving a large patient population suffering
from infectious diseases, cancer, and multiple sclerosis. Our commercial and market access team has been diligently working alongside
our research and development team and external experts to better understand market dynamics, identify segments with high unmet needs,
map the patient journey, understand the competition within each segment, and identify opportunities for our product candidates. The same
team continues to offer input in portfolio planning and target prioritization for our research pipeline. We are also proactive in identifying
potential collaboration and service partners, including distribution partners for our sophisticated, cryopreserved cell therapy products
like TVGN 489. As part of our company’s mission of patient centricity, we aim to collaborate with all stakeholders, including patients,
healthcare professionals, sales channel partners, public and private payers, and service providers. Essential commercial capabilities,
such as market analytics, pricing, and commercial operations functions, are continuously being developed as we progress toward the later-stage
development of TVGN 489.
21
Artificial
Intelligence
In
October 2023, we announced Tevogen.ai, a new early-stage initiative focused on harnessing the potential of artificial intelligence to
expedite drug development, optimize laboratory processes and clinical trials, unravel complex biological data, improve patient outcomes,
and pass on related savings to patients. We intend to assemble a team of research scientists, physicians, data scientists, and artificial
intelligence and machine learning engineers to help accomplish these goals by leveraging tools and techniques that might include large,
curated data sets, algorithmic models, pattern recognition, data analyses, automation, and artificial intelligence-powered software such
as chatbots. As an initial part of this initiative, we are specifically exploring ways to deploy artificial intelligence-powered target
detection to further accelerate our product development pace, either internally or in collaboration with leading entities in the field
of artificial intelligence. We also intend to explore the potential use of artificial intelligence to power tools that could anticipate
potential adverse reactions and efficacy concerns for and identify patients who would be most likely to respond to an investigational
therapy. The ability to search the human genome for specific peptide sequences might, for example, eliminate some peptide targets simplifying
the peptide screening/selection process. We have filed patents for algorithms to be trained against a curated dataset to predict immunologically
active HLA-peptide complexes and additionally to predict T-cell receptor engagement tied to specific HLA-peptide complexes.
Our
History and Team
We
were incorporated as a Cayman Islands exempted company in April 2021, and Tevogen Bio was established in June 2020 as a Delaware corporation.
Our senior leadership team is composed of eminent scientists and accomplished biopharmaceutical leaders. The team brings together diverse
experience across the entire life sciences spectrum, including biotechnology, pharmaceuticals, hospitals, public and private insurance,
education, and health policy. Additionally, our team holds substantial expertise in drug development, global product launches, and commercialization
and ensuring patient access across a range of therapeutic areas.
Competition
The
biotechnology industry, and in particular the cell therapy sector, are characterized by the rapid evolution of technologies and understanding
of disease etiology, and strong pursuit and defense of intellectual property. We believe that our approach, strategy, scientific development
capabilities, know-how, access to global experts, and experience provide us with competitive advantages. However, we expect future competition
in some of the indications we are targeting and from existing or emerging pharmaceutical and biotechnology companies as well as possibly
from governmental agencies, academic institutions, and public and private research institutions, among others. Some of our competitors,
either alone or through collaborations, have greater financial resources and expertise in research and development, conducting clinical
trials, manufacturing, obtaining regulatory approvals, and marketing approved products than we do. Smaller or early-stage companies may
also prove to be competitors, particularly through collaborative arrangements with large and established companies. Entities in the biotechnology
industry also compete with us in recruiting and retaining qualified scientific, clinical, and management personnel and may compete with
us in establishing clinical trial sites and enrolling patients in clinical trials as well as in acquiring technologies complementary
to, or necessary for, our programs. As a result, our competitors may discover, develop, license, or commercialize products before or
more successfully than we do.
TVGN
489 is being developed to fill the critical gaps that exist in COVID-19 therapeutics for the immunocompromised and the high-risk elderly.
No treatments are specifically approved for immunocompromised patients as of the date of this Annual Report, and clinical trial data
of currently approved treatments in immunocompromised patients is limited. The National Institutes of Health’s (“NIH”)
COVID-19 Treatment Guidelines Panel, a group of clinical experts that has developed guidance on COVID-19 care (the “NIH Panel Guidelines”),
currently recommends prompt treatment of COVID-19 in non-hospitalized immunocompromised patients with antiviral drugs, but acknowledges
the limitations of these drugs and related research in such patients. Two antivirals are currently FDA-approved for COVID-19 treatment:
Gilead Science’s Veklury ® (Remdesivir) for the treatment of mild-to-moderate COVID-19 in hospitalized or non-hospitalized
adults who are at high risk for progression to severe COVID-19, and Pfizer’s Paxlovid (Nirmatrelvir/Ritonavir tablets) for the
treatment of mild-to-moderate COVID-19 in adults who are at high risk for progression to severe COVID-19. The NIH Panel Guidelines highlight
the limitation of the insights that clinical trials conducted for Remdesivir and for Nirmatrelvir/Ritonavir tablets in broader populations
can provide with respect to immunocompromised patients, as each trial enrolled only limited numbers of such patients. For example, a
retrospective study examining the use of Nirmatrelvir/Ritonavir tablets in vulnerable individuals with COVID-19 included only 13.2% highly
immunocompromised and 10.6% moderately immunocompromised patients with cancer, with cancer type and type immunosuppressive medications
not otherwise specified. Although the NIH Panel Guidelines acknowledge observation in retrospective studies of “some potential
benefits” of the use of Paxlovid for patients with “various immunocompromising conditions,” they also note that because
the pivotal trial of Nirmatrelvir/Ritonavir tablets did not enroll many immunocompromised participants, “efficacy ... was not established
for this population.” Based on our target product profile, therefore, we anticipate that these products may not be direct competitors
in our target patient population. Moreover, we believe that TVGN 489’s anticipated single outpatient infusion may be easier to
administer than Veklury’s multiple infusions over a number of days. Additionally, Paxlovid requires daily doses, has a significant
number of drug interaction issues, as discussed in “COVID-19 Background” and noted by the NIH Panel Guidelines, and has experienced
numerous patient reports of disease relapse or rebound, which in each case we do not anticipate for TVGN 489 based on its design and
our Phase 1 proof of concept trial results. We do expect that these products may present direct competition in high-risk elderly patients,
but we are initially targeting immunocompromised indications.
22
Monoclonal
antibodies have also previously been considered promising as an effective therapeutic option for COVID-19, including in immunocompromised
patients, and several had been granted EUAs. However, these treatments have had their EUAs revoked by FDA due to lack of efficacy stemming
from viral mutations. For example, AstraZeneca’s Evusheld (tixagevimab co-packaged with cilgavimab), a monoclonal antibody pair
that previously had an EUA granted on December 8, 2021, for preventive use in immunocompromised patients, was undermined by viral mutations,
resulting in the revocation of its EUA in January 2023, only 13 months later. Evushield had previously been associated with a reduced
risk of mortality in ancestral strains of COVID-19, but the results of a trial reported in February 2024 showed that Evushield failed
to impact patient clinical status or increase viral clearance in hospitalized COVID-19 patients. This finding was thought to be due at
least in part to evasion of the therapy by newer COVID-19 variants, highlighting the difficulty of applying monoclonal antibody treatments
to COVID-19 therapy. There are nonetheless ongoing efforts to develop additional anti-COVID monoclonal antibodies for treatment and prevention
of Covid-19 infection. For example, in January 2024, Invivyd applied to FDA for EUA of its product, VYD222, a broadly neutralizing monoclonal
antibody used for COVID-19 prevention in immunocompromised individuals. While this product has shown in vitro activity against a currently
circulating variant, JN.1, it may remain vulnerable to novel viral mutations. Antibodies, unlike T-cells, recognize intact molecules.
Consequently, even remote mutations, not directly where the antibodies bind, may alter how the target molecule folds and its overall
shape and therefore prevent antibody binding. T-cells, in contrast, recognize small peptide breakdown products of proteins and are only
affected if the mutation is directly within the target peptide. Although it is possible that the epitope targeted by VYD 222 and others
like it will remain more durable, this remains to be seen.
More
broadly, known companies developing virus-specific T cell therapies include Atara Biotherapeutics (“Atara Bio”), whose Ebvallo
(tabelecleucel) has received approval in Europe for treating a rare hematologic cancer caused by EBV. AlloVir, Inc. (“AlloVir”) is another company developing
allogeneic T cell therapies for viral diseases. Neither Atara Bio nor AlloVir has an active development program for the treatment of
COVID-19. AlloVir conducted a Phase 1b trial of an allogeneic, partially HLA-matched product candidate in COVID-19 and reported results
of the trial in 2021 but has not continued clinical development. One patient in the trial experienced a recurrence of the disease and
died four weeks after treatment. Atara Bio announced in November 2023 that the Phase 2 trial of its T cell therapy, ATA 188, targeting
EBV-infected B cells and plasma cells in progressive forms of multiple sclerosis, failed to meet efficacy or biomarker endpoints. Patients
initially treated with placebo in this trial later received ATA 188, which we believe may have made it more challenging to discern a
difference between the study arms. ATA 188 targets only three latent EBV proteins, whereas our CTL peptide targets are selected from
all proteins expressed at the appropriate point in the viral life cycle, whether unique to that point in the viral life cycle or not.
This approach provides far more immunologic targets and thus more opportunities for viral control. In addition, ATA 188 is generated
against targets restricted by several HLA alleles, which is likely to reduce the functional dose of drug targeting any one HLA allele,
as contrasted with CTLs developed with ExacTcell, which are generated against a single HLA specificity and therefore allow a more precise
understanding and control of dosage.
We
anticipate that we may face competition as new therapies enter the market and advanced technologies become available from time to time.
We expect that any treatments which we develop and commercialize will need to compete on, among other things, efficacy, safety, convenience
of administration and delivery, and price. Commercialization of any treatments we develop will be affected by the level of competition
from original and biosimilars products and the availability of reimbursement from government and other third-party payors.
23
Our
ability to commercialize our proprietary cell products could be significantly and adversely affected if our competitors develop and commercialize
products that are more effective, have a better safety profile, are more convenient or are less expensive than our products. Our competitors
also may obtain relevant regulatory approvals for their products more rapidly than we may be able to obtain approval for ours, which
could result in our competitors obtaining a head start and establishing a frontrunner position before we are ready to commercialize.
If we are not able to compete effectively against our existing and potential competitors, our business, financial condition, results
of operations and growth prospects may be materially and adversely affected.
Intellectual
Property
Our
commercial success depends in part on our ability to obtain and maintain patent and other proprietary protection for our products and
methods, preserve the confidentiality of our trade secrets, operate without infringing, misappropriating, or otherwise violating the
valid, enforceable proprietary rights of others, and prevent others from infringing, misappropriating, or otherwise violating our proprietary
rights. We rely on a combination of patents, patent applications, and trade secrets to establish and protect our intellectual property
rights. Our ability to stop third parties from making, using, selling, offering to sell, or importing our products without the right
to do so may depend on the extent to which we have rights under valid and enforceable patents or trade secrets that cover these activities.
We
continue to build our intellectual property portfolio and seek to protect our proprietary position by, among other things, filing patent
applications. Our patent estate includes patents and patent applications with claims relating to our product candidates, methods of use,
and methods of preparing the product candidates. As of March 15, 2024, our U.S. intellectual property portfolio includes three U.S. patents
relating to TVGN 489 for the treatment of COVID-19, nine pending U.S. patent applications, including two patent applications relating
to the treatment of COVID-19, five relating to the treatment of other viruses or cancer, and two related to artificial intelligence-driven
T cell target identification and receptor engagement, as well as eleven ex-U.S. patent applications, including applications in Australia,
Canada, Europe, Japan, Qatar, and United Arab Emirates directed at viral specific T cells, methods of treating and preventing viral infections,
and methods for developing CD3+CD+ cells against multiple viral epitopes for the treatment of viral infections, which have anticipated
expiration dates through July 29, 2042.
In
the United States, our three issued utility patents, all of which will expire on December 9, 2040, are U.S. Patent No. 11,191,827 covering
methods of treating COVID-19 infection using COVID-19 peptide specific CTLs, U.S. Patent No. 11,207,401 covering COVID-19 peptide-specific
CTLs, and U.S. Patent No. 11,219,684 covering methods of manufacturing COVID-19 peptide specific CTLs. A pending utility patent application
in the United States directed at viral specific T cells and methods of treating and preventing viral infections has an anticipated expiration
of December 9, 2041.
In
addition, we have applied for registered trademark protection for “Tevogen Bio” (and design) as well as “ExacTcell”
with the U.S. Patent and Trademark Office (the “USPTO”).
We
determine strategy for claim scope for our patent applications on a case-by-case basis, taking into account advice of counsel and our
business model and needs. We file patents containing claims for protection of useful applications of our proprietary technologies and
any product candidates, including new applications or uses we discover for existing technologies and product candidates, based on our
assessment of their strategic value. We continuously reassess the number and type of patent applications, as well as our pending and
issued patent claims, to ensure maximum coverage and value are obtained for our processes and compositions, given existing patent office
rules and regulations.
Human
Capital Resources
Our
success depends on our ability to attract and retain highly qualified management and personnel. As of April 26, 2024, we had 17 full-time
and no part-time employees. We value a work culture that encourages employees, contractors, and vendors to contribute their unique and
diverse perspectives, to harness optimism and creativity, and to be ready to learn and develop solutions towards a common and greater
purpose of developing accessible immunotherapies. Our work culture is centered around four “CORE” values: Curiosity, Optimism,
Respect, and Equality. We believe it is essential and necessary that these values are instilled and maintained in each of our employees
to foster a collaborative culture. At our current size, ensuring this culture is primarily achieved through the recruitment process.
Talent recruitment at our current stage is setting the foundation for further company growth. When attracting talent, we ensure that
every job description mentions our core values, and the importance of these values in achieving our mission. Beyond evaluating experience,
job applicants are also evaluated based on their values and passions. We believe it is necessary that each employee represents our four
core values. As our employee numbers increase, we plan to create more defined programs to further enhance our company culture and retention
of personnel.

Regulatory
Environment
Government
Regulation and Product Approval
In
the United States, biological products are subject to regulation under the Federal Food, Drug, and Cosmetic Act (the “FDCA”),
and the Public Health Service Act (the “PHSA”), and other federal, state, and local statutes and regulations. Both the FDCA
and PHSA and their corresponding regulations govern, among other things, the research, development, clinical trials, testing, manufacturing,
quality control, safety, purity and potency (efficacy), labeling, packaging, storage, record keeping, distribution, reporting, marketing,
promotion, advertising, post-approval monitoring, and post-approval reporting involving biological products. Along with third-party contractors,
we will be required to navigate the various preclinical and clinical regulatory obligations and the commercial approval requirements
of the governing regulatory agencies of the countries in which we wish to conduct studies or seek approval or licensure of our product
candidates. The processes for obtaining regulatory approvals in the United States, along with subsequent compliance with applicable laws
and regulations and other regulatory authorities, require the expenditure of substantial time and financial resources.
Government
policies may change and additional government regulations may be enacted that could prevent or delay further development or regulatory
approval of any product candidates, product or manufacturing changes, additional disease indications or label changes. We cannot predict
the likelihood, nature or extent of government regulation that might arise from future legislative or administrative action.
Review
and Approval for Licensing Biologics in the United States
In
the United States, FDA regulates our current product candidates as biological products, or biologics, under the FDCA, the PHSA, and associated
implementing regulations. Biologics, like other drugs, are used for the diagnosis, cure, mitigation, treatment, or prevention of disease
in humans. In contrast to low molecular weight drugs, which have a well-defined structure and can be thoroughly characterized, biologics
are generally derived from living material (human, animal, or microorganism), are complex in structure, and thus are usually not fully
characterized.
Biologics
are also subject to other federal, state, and local statutes and regulations. The failure to comply with applicable statutory and regulatory
requirements at any time during the product development process, approval process, or after approval may subject a sponsor or applicant
to administrative or judicial enforcement actions. These actions could include the suspension or termination of clinical trials by FDA,
FDA’s refusal to approve pending applications or supplemental applications, withdrawal of an approval, issuance of warning or untitled
letters, product recalls, product seizures, total or partial suspension of production or distribution, import detention, injunctions,
fines, refusals of government contracts, restitution, disgorgement of profits, or civil or criminal investigations and penalties brought
by FDA, the Department of Justice (“DOJ”), and other governmental entities.
An
applicant seeking approval to market and distribute a biologic in the United States must typically undertake the following:
●
completion
of non-clinical laboratory tests and studies performed in accordance with FDA’s good laboratory practice (“GLP”)
regulations;
●
manufacture,
labeling and distribution of investigational drugs in compliance with FDA’s current good manufacturing practice (“cGMP”)
requirements;
25
●
submission
to FDA of an IND, which must become effective before clinical trials may begin and must be updated annually and when significant
changes are made;
●
approval
by an independent institutional review board (“IRB”) for each clinical site before each clinical trial may be initiated;
●
performance
of adequate and well-controlled human clinical trials in accordance with FDA’s Good Clinical Practices (“GCP”)
to establish the safety, purity, and potency of the proposed biological product candidate for its intended purpose;
●
after
completion of all pivotal clinical trials, preparation of and submission to FDA of a Biologics License Application (“BLA”)
requesting marketing approval, which includes providing sufficient evidence to establish the efficacy, safety, purity, and potency
of the proposed biological product for its intended use, including from results of nonclinical testing and clinical trials;
●
satisfactory
completion of an FDA advisory committee review, when appropriate, as may be requested by FDA to assist with its review;
●
satisfactory
completion of one or more FDA inspections of the manufacturing facility or facilities at which the proposed product, or certain components
thereof, are produced to assess compliance with cGMP and data integrity requirements to assure that the facilities, methods, and
controls are adequate to preserve the biological product’s identity, strength, quality, and purity and, if applicable, FDA’s
good tissue practice (“GTP”) requirements for human cellular and tissue products;
●
satisfactory
completion of FDA inspections of selected clinical investigation sites to assure compliance with GCP requirements and the integrity
of the clinical data;
●
satisfactory
completion of an FDA sponsor GCP inspection, often conducted at the applicant’s headquarters facility;
●
payment
of user fees (unless there is a waiver, exemption, or reduction) under the Prescription Drug User Fee Act (“PDUFA”) for
the relevant year;
●
FDA’s
review and approval of the BLA to permit commercial marketing of the licensed biologic for particular indications for use in the
United States;
●
compliance
with post-approval requirements, including the potential requirements to implement a Risk Evaluation and Mitigation Strategy (“REMS”),
to report adverse events and biological product deviations, and to complete any post-approval studies; and
●
completion
of any post-approval clinical studies required by FDA, such as confirmatory trials or pediatric studies.
From
time to time, legislation is drafted, introduced, and passed in Congress that could significantly change the statutory provisions governing
the testing, approval, manufacturing, and marketing of biological products regulated by FDA. In addition to new legislation, FDA regulations,
guidance documents, and policies are often revised or interpreted by the agency in ways that may significantly affect the regulation
of biological products in the United States. It is impossible to predict whether further legislative changes will be enacted or whether
FDA regulations, guidance, policies, or interpretations will change, and the effects of any such changes.
26
Preclinical
and Clinical Development
Before
an applicant can begin testing the potential product candidate in human subjects, the applicant must first conduct preclinical studies.
Preclinical studies may include laboratory evaluations of product chemistry, toxicity, and formulation, as well as in vitro and animal
studies to assess the potential safety and activity of the drug for initial testing in humans and to establish a rationale for therapeutic
use. Preclinical studies are subject to federal regulations and requirements, including GLP regulations, which govern the conduct of
animal studies designed to test a product’s safety. None of our preclinical studies to date have been animal studies. The results
of an applicant’s preclinical studies are submitted to FDA as part of an IND.
An
IND is a request for authorization from FDA to administer an investigational new drug product to humans. An IND is an exemption from
the FDCA that allows an unapproved drug to be shipped in interstate commerce for use in a clinical trial. Such authorization must be
secured prior to interstate shipment and administration of a biological drug that is not subject of an approved BLA. In support of an
IND, applicants must submit a protocol for each clinical trial, which details, among other things, the objectives of the trial, the parameters
to be used in monitoring safety and the effectiveness criteria to be evaluated. A separate submission to the existing IND must be made
for each successive clinical trial conducted during product development and for any subsequent protocol amendments.
Human
clinical trials may not begin until an IND is effective. The IND automatically becomes effective 30 days after receipt by FDA, unless
FDA raises safety concerns or questions about the proposed clinical trial within the 30-day time period. In such a case, FDA may place
the IND on clinical hold and the IND sponsor must resolve any of FDA’s outstanding concerns or questions before the clinical trial
can begin. Submission of an IND therefore may or may not result in regulatory authorization to begin a clinical trial.
FDA
may also place a clinical hold or partial clinical hold on a clinical trial following commencement of the trial under an IND. A clinical
hold is an order issued by FDA to the sponsor to delay a proposed clinical investigation or to suspend an ongoing investigation. A partial
clinical hold is a delay or suspension of only part of the clinical work requested under the IND. For example, under a partial clinical
hold, FDA may instruct a sponsor not to enroll any new patients into a study, but permit the previously enrolled patients to continue
in the study. No more than 30 days after imposition of a clinical hold or partial clinical hold, FDA will provide the sponsor a written
explanation of the basis for the hold. Following issuance of a clinical hold or partial clinical hold, an investigation may only resume
after FDA has notified the sponsor that the investigation may proceed. FDA will base that determination on information provided by the
sponsor addressing the deficiencies previously cited or otherwise satisfying FDA that the investigation can proceed.
Clinical
trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators in
accordance with GCP regulations, which include the requirement that all research subjects provide their informed consent for their participation
in any clinical trial. If a sponsor chooses to conduct a foreign clinical study under an IND, all FDA IND requirements must be met unless
waived. When the foreign clinical study is not conducted under an IND, the sponsor must ensure that the study complies with GCP regulations
in order to use the study as support for an IND or application for marketing approval, including review and approval by an IRB and informed
consent from subjects.
Furthermore,
an independent IRB for all sites participating in a clinical trial must review and approve the plan for any clinical trial and its informed
consent form before the clinical trial begins at each site, and must monitor the trial until completed. Regulatory authorities, the IRB,
or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to
an unacceptable health risk or that the trial is unlikely to meet its stated objectives.
Some
trials also include oversight by an independent group of qualified experts organized by the clinical trial sponsor, known as a data safety
monitoring board (“DSMB”). DSMBs review unblinded study data at pre-specified times during the course of the study. If the
DSMB determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy, the DSMB
can make a recommendation to the sponsor to modify or stop the trial.
Other
grounds for a sponsor’s decision to suspend or terminate a study may be made based on evolving business objectives or competitive
climate.
27
For
purposes of BLA approval, clinical trials are typically conducted in the following sequential phases:
● Phase
1: The investigational product is initially introduced into a small group of healthy human
subjects or patients with the target disease or condition. These trials are designed to test
the safety, dosage tolerance, absorption, metabolism and distribution of the investigational
product in humans and the side effects associated with increasing doses. These trials may
also yield early evidence of effectiveness.
● Phase
2: The investigational product is administered to a slightly larger patient population with
a specified disease or condition to evaluate the preliminary efficacy, optimal dosages, and
dosing schedule and to identify possible adverse side effects and safety risks. Multiple
Phase 2 clinical trials may be conducted to obtain information prior to beginning larger
and more expensive Phase 3 clinical trials.
● Phase
3: The investigational product is administered to an expanded patient population to further
evaluate dosage, to provide statistically significant evidence of clinical efficacy and to
further test for safety, generally at multiple geographically dispersed clinical trial sites.
These clinical trials are intended to generate sufficient data to statistically demonstrate
the efficacy and safety of the product, to establish the overall risk/benefit ratio of the
investigational product, and to provide an adequate basis for product approval by FDA.
These
phases may overlap or be combined. In some cases, FDA may require, or companies may voluntarily pursue, additional clinical trials after
a product is approved to gain more information about the product, referred to as Phase 4 trials.
Such post-approval trials are conducted following initial approval, often to develop additional data and information relating to the
use of the product in new indications.
Progress
reports detailing the results of the clinical trials must be submitted at least annually to FDA. In addition, IND safety reports must
be submitted to FDA for any of the following: serious and unexpected suspected adverse reactions in study subjects; findings from epidemiological
studies, pooled analysis of multiple studies, animal or in vitro testing, or other clinical studies, whether or not conducted under an
IND, and whether or not conducted by the sponsor, that suggest a significant risk in humans exposed to the drug; and any clinically important
increase in the rate of a serious suspected adverse reaction over such rate listed in the protocol or investigator brochure.
A
sponsor’s planned clinical trials may not be completed successfully within any specified period, or at all. Furthermore, FDA or
the sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects
are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution,
or an institution it represents, if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the
drug has been associated with unexpected serious harm to patients. FDA will typically inspect one or more clinical sites to assure compliance
with GCP and the integrity of the clinical data submitted.
During
clinical development, the sponsor often refines the indication and endpoints on which the BLA will be based. For endpoints based on patient-reported
outcomes (“PROs”), the process typically is an iterative one. FDA has issued guidance on the framework it uses to evaluate
PRO instruments. Although the agency may offer advice on optimizing PRO instruments during the clinical development process, FDA usually
reserves final judgment until it reviews the BLA.
Concurrent
with clinical trials, companies often complete additional animal studies, and develop additional information about the chemistry and
physical characteristics of the drug and finalize a process for manufacturing the product in commercial quantities in accordance with
cGMP. The manufacturing process must be capable of consistently producing quality batches of the drug candidate and, among other things,
must develop methods for testing the identity, strength, quality, purity and potency of the final drug. Additionally, appropriate packaging
must be selected and tested, and stability studies must be conducted to demonstrate that the drug candidate does not undergo unacceptable
deterioration over its shelf life.
BLA
Submission and Review
Assuming
successful completion of all required clinical testing in accordance with all applicable regulatory requirements, an applicant may submit
a BLA requesting licensing to market the biologic for one or more indications in the United States. The BLA must include the results
of nonclinical studies and clinical trials; detailed information on the product’s chemistry, manufacture, controls; and proposed
labeling. Under the PDUFA, a BLA submission is subject to an application user fee, unless a waiver, reduction, or exemption applies.
28
FDA
will initially review the BLA for completeness before accepting it for filing. Under FDA’s procedures, the agency has 60 days from
its receipt of a BLA to determine whether the application will be accepted for filing and substantive review. If the agency determines
that the application does not meet this initial threshold standard, FDA may refuse to file the application and request additional information,
in which case the application must be resubmitted with the requested information and review of the application delayed.
After
the BLA is accepted for filing, FDA reviews the BLA to determine, among other things, whether a product is safe, pure, and potent and
if the facility in which it is manufactured, processed, packed, or held meets standards designed to assure the product’s continued
identity, strength, quality, safety, purity, and potency. To ensure cGMP, GLP, GCP, GTP, and other regulatory compliance, an applicant
must incur significant expenditure of time, money, and effort in the areas of training, record keeping, production and quality control.
In addition, FDA expects that all data be reliable and accurate, and requires sponsors to implement meaningful and effective strategies
to manage data integrity risks. Data integrity is an important component of the sponsor’s responsibility to ensure the safety,
efficacy and quality of its product or products.
For
cellular products, FDA will not approve the product if the manufacturer is not in compliance with the GTPs, to the extent applicable.
GTPs are FDA regulations and guidance documents that govern the methods used in, and the facilities and controls used for, the manufacture
of human cells, tissue, and cellular and tissue-based products (“HCT/Ps”), which are human cells or tissue intended for implantation,
transplant, infusion, or transfer into a human recipient. The primary intent of the GTP requirements is to ensure that cell and tissue-based
products are manufactured in a manner designed to prevent the introduction, transmission and spread of communicable disease. FDA regulations
also specify how HCT/P establishments must register and list their HCT/Ps with FDA and how they must evaluate donors through screening
and testing, where applicable.
If
FDA determines that the application, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies
in the submission and often will request additional testing or information. Notwithstanding the submission of any requested additional
information, FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.
The
performance goals and policies implemented by FDA under the PDUFA generally provide for FDA action on an original BLA within 10 months
of filing, which (as discussed above) typically occurs within 60 days of submission, but that deadline is extended in certain circumstances.
Furthermore, the review process is often significantly extended by FDA’s requests for additional information or clarification.
FDA
may refer applications for novel products or products that present difficult questions of safety or efficacy to an advisory committee.
Typically, an advisory committee consists of a panel that includes clinicians and other experts who will review, evaluate, and provide
a recommendation as to whether the application should be approved and, if so, under what conditions. FDA is not bound by the recommendations
of an advisory committee, but it considers such recommendations carefully when making decisions and usually has followed such recommendations.
After
FDA evaluates a BLA and conducts inspections of manufacturing facilities where the investigational product and/or its components will
be produced, FDA may issue an approval letter or a Complete Response Letter (“CRL”).
An approval letter authorizes commercial marketing of the biologic with specific prescribing information for specific indications. A
CRL will describe all of the deficiencies that FDA has identified in the BLA, except that where FDA determines that the data supporting
the application are inadequate to support approval, FDA may issue the CRL without first conducting required inspections, testing submitted
product lots and/or reviewing proposed labeling. If and when the deficiencies have been addressed to FDA’s satisfaction in a resubmission
of the BLA, FDA will issue an approval letter. In issuing the CRL, FDA may recommend actions that the applicant might take to place the
BLA in condition for approval, including requests for additional data, information, or clarification. FDA may delay or refuse approval
of a BLA if applicable regulatory criteria are not satisfied, and may require additional testing or information and/or require new clinical
trials. Even with submission of this additional information, FDA ultimately may decide that the application does not satisfy the regulatory
criteria for approval.
29
During
the approval process, FDA will determine whether a REMS is necessary to help ensure the benefits outweigh the risks of the biologic.
A REMS is a safety strategy to manage a known or potential serious risk associated with a product and to enable patients to have continued
access to such medicines by managing their safe use, and 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. If FDA concludes that
a REMS is needed, the BLA sponsor must submit a proposed REMS and FDA will not approve the BLA without a REMS that the agency has determined
is acceptable.
If
FDA approves a product, it may limit the approved indications for use for the product, or require that contraindications, warnings, or
precautions be included in the product labeling. FDA may also require that post-approval studies, including Phase
4 clinical trials, be conducted to further assess the drug’s safety after approval. FDA may prevent or limit further marketing
of a product based on the results of post-market studies or surveillance programs.
FDA
may also require testing and surveillance programs to monitor the product after commercialization. For biologics, such testing may include
official lot release, which requires the manufacturer to perform certain tests on each lot of the product before it is released for distribution.
The manufacturer then typically must submit samples of each lot of product to FDA, together with a release protocol showing a summary
of the history of manufacture of the lot and the results of all of the manufacturer’s tests performed on the lot. FDA may also
perform certain confirmatory tests on lots of some products itself, before releasing the lots for distribution by the manufacturer.
In
general, an approved BLA only allows the sponsor to market the biologic as approved, without modification. If, for example, a sponsor
modifies an approved T cell product to target different peptides or in our case to target another HLA type, the sponsor would be required
to either file a supplemental BLA with FDA or receive FDA approval for a comparability protocol in order to implement this change into
the final product.
FDA
may withdraw the product approval if compliance with pre- and post-marketing requirements is not maintained or if problems occur after
the product reaches the marketplace.
Post-Approval
Requirements
Any
products manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by FDA, including,
among other things, requirements relating to recordkeeping, periodic reporting, reporting of certain deviations and adverse experiences,
product sampling and distribution, and advertising and promotion of the product. After approval, many types of changes to the approved
product, such as adding new indications, manufacturing changes and additional labeling claims, are often subject to further testing requirements
and FDA review and approval, depending on the nature of the post-approval change. There also are continuing user fee requirements, under
which FDA assesses an annual program fee for each product identified in an approved BLA. Biologic manufacturers and their third-party
contractors are required to register their facilities with FDA and certain state agencies. These facilities are subject to routine and
periodic unannounced inspections by FDA and certain state agencies for compliance with cGMP, post-marketing safety reporting and data
integrity requirements, which impose certain procedural and documentation requirements to assure quality of manufacturing and product.
FDA has increasingly observed cGMP violations involving data integrity during site inspections and is a significant focus of its oversight.
Requirements with respect to data integrity include, among other things, controls ensuring complete and secure data; activities documented
at the time of performance; audit trail functionality; authorized access and limitations; validated computer systems; and review of records
for accuracy, completeness, and compliance with established standards.
Post-approval
changes to the manufacturing process are strictly regulated, and, depending on the significance of the change, may require FDA approval
before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting
requirements upon the sponsor and any third-party manufacturers that the sponsor may use. Accordingly, manufacturers must continue to
expend time, money, and effort in the area of production and quality control to maintain compliance with cGMP, data integrity, pharmacovigilance,
and other aspects of regulatory compliance.
30
FDA
may withdraw the approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product
reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity
or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved
labeling to add new safety information; imposition of post-approval studies to assess new safety risks; or imposition of distribution
or other restrictions under a REMS. Other potential consequences include, for example:
●
restrictions
on the marketing or manufacturing of a product, complete withdrawal of the product from the market, or product recalls;
●
fines,
warning or untitled letters, or holds on post-approval clinical studies;
●
refusal
of FDA to approve pending applications or supplements to approved applications, or suspension or revocation of existing product approvals;
●
product
seizure or detention, or refusal of FDA to permit the import or export of products; or
●
permanent
injunctions and consent decrees, including the imposition of civil or criminal penalties.
FDA
strictly regulates the marketing, labeling, advertising, and promotion of prescription drug products placed on the market. A company
can make only those claims relating to safety and efficacy, purity and potency that are approved by FDA and in accordance with the provisions
of the approved labeling. FDA’s regulation includes, among other things, standards and regulations for direct-to-consumer advertising,
communications regarding unapproved uses, industry-sponsored scientific and educational activities and promotional activities involving
the Internet and social media. Promotional claims relating to a product’s safety or effectiveness are prohibited before the drug
is approved. After approval, a product generally may not be promoted for uses that are not approved by FDA, as reflected in the product’s
prescribing information. In the United States, healthcare professionals are generally permitted to prescribe drugs for such uses not
described in the drug’s labeling, known as off-label uses, because FDA does not regulate the practice of medicine. However, FDA
regulations impose rigorous restrictions on manufacturers’ communications and prohibit the promotion of off-label uses. It may
be permissible, under very specific, narrow conditions, for a manufacturer to engage in non-promotional, non-misleading communication
regarding off-label information, such as distributing scientific or medical journal information.
If
a company is found to have promoted off-label uses, it may become subject to adverse public relations and administrative and judicial
enforcement by FDA, the DOJ, or the Office of the Inspector General of the Department of Health and Human Services (“HHS”),
as well as other federal and state authorities. This could subject a company to a range of penalties that could have a significant commercial
impact, including civil, administrative, and criminal fines, penalties, and agreements that materially restrict the manner in which a
company promotes or distributes products. The federal government has levied large civil, administrative, and criminal fines and penalties
against companies for alleged improper promotion, and has also requested that companies enter into Corporate
Integrity Agreements and Consent Decrees of Permanent Injunction under which specified promotional conduct is changed or curtailed.
The
distribution of prescription drugs and biologics are subject to the Drug Supply Chain Security Act (“DSCSA”), which requires
manufacturers and other stakeholders to comply with product identification, tracing, verification, detection and response, notification,
and licensing requirements. In addition, the Prescription Drug Marketing Act and its implementing regulations and state laws limit the
distribution of prescription pharmaceutical product samples, and the DSCSA imposes requirements to ensure accountability in distribution
and to identify and remove prescription drug and biological products that may be counterfeit, stolen, contaminated, or otherwise harmful
from the market.
31
Expedited
Development and Review Programs
FDA
offers a number of expedited development and review programs for qualifying product candidates. The fast-track program is intended to
expedite or facilitate the process for reviewing new products that meet certain criteria. Specifically, new products 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. A product intended to treat a serious or life-threatening disease or condition
may also be eligible for breakthrough therapy designation to expedite its development and review. Any marketing application for a biologic
submitted to FDA for approval, including a product with a fast-track designation and/or breakthrough therapy designation, may be eligible
for other types of FDA programs intended to expedite FDA review and approval process, such as priority review and accelerated approval.
FDA also may grant accelerated approval to certain products studied for their safety and effectiveness in treating serious or life-threatening
diseases or conditions.
The
RMAT designation, which we are currently planning to seek for some of our therapies, is intended to facilitate an efficient development
program for, and expedite review of, any drug that meets the following criteria: (1) the drug is a cell therapy, therapeutic tissue engineering
product, human cell and tissue product, or any combination product using such therapies or products, with limited exceptions; (2) the
drug is intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition; and (3) preliminary clinical
evidence indicates that the drug has the potential to address unmet medical needs for such a disease or condition. Like breakthrough
therapy designation, RMAT designation provides potential benefits that include more frequent meetings with FDA to discuss the development
plan for the product candidate and eligibility for rolling review and priority review. Products granted RMAT designation may also be
eligible for accelerated approval on the basis of a surrogate or intermediate endpoint reasonably likely to predict long-term clinical
benefit, or reliance upon data obtained from a meaningful number of sites (including through expansion to additional sites) so as to
remove any likelihood of site-specific or investigator-specific bias on the evidence of effectiveness. Once approved, when appropriate,
FDA can permit fulfillment of post-approval requirements for RMATs receiving accelerated approval through the submission of clinical
evidence, clinical studies, patient registries, or other sources of real-world evidence such as electronic health records; through the
collection of larger confirmatory datasets; or through post-approval monitoring of all patients treated with the therapy prior to approval.
Fast
track designation, breakthrough therapy designation, priority review, accelerated approval, and RMAT designation do not change the standards
for approval but may expedite the development or approval process.
Patent
Term Restoration and Marketing Exclusivity
After
approval, owners of relevant drug or biological product patents may apply for up to a five year term patent extension to restore a portion
of patent term lost during product development and FDA review of a BLA if approval of the application is the first permitted commercial
marketing or use of a drug or biologic containing the active ingredient under the Drug Price Competition and Patent Term Restoration
Act of 1984, referred to as the Hatch-Waxman Act. The allowable patent term extension is
calculated as one-half of the product’s testing phase, which is the time between the effective date of an IND and initial BLA submission,
and all of the approval phase, which is the time between BLA submission and approval, up to a maximum of five years. The time can be
shortened if FDA determines that the applicant did not pursue approval with due diligence. The total patent term after the extension
may not exceed 14 years from the date of FDA approval of the product. Only one patent claiming each approved product is eligible for
restoration and the patent holder must apply for restoration within 60 days of approval, even if the product cannot be commercially marketed
at that time. The USPTO, in consultation with FDA, reviews and approves the application for patent term restoration.
For
patents that might expire during the BLA application phase, the patent owner may request an interim patent extension. An interim patent
extension increases the patent term by one year and may be renewed up to four times. For each interim patent extension granted, the post-approval
patent extension is reduced by one year. The director of the USPTO must determine that approval of the product candidate covered by the
patent for which a patent extension is being sought is likely. Interim patent extensions are not available for a product candidate for
which a BLA has not been submitted.
32
Biosimilars
and Marketing Exclusivities
The
Biologics Price Competition and Innovation Act (“BPCIA”) created an abbreviated approval
pathway for biological product candidates shown to be highly similar to or interchangeable with an FDA licensed biological product. A
biological product on which another biological product candidate’s BLA relies to establish biosimilarity is known as a reference
product. Biosimilarity sufficient to reference a prior FDA-approved product requires that there be no differences in conditions of use,
route of administration, dosage form and strength, and no clinically meaningful differences between the biological product candidate
and the reference product in terms of safety, purity, and potency. Biosimilarity must be shown through analytical trials, animal trials
and at least one clinical trial, unless the Secretary of HHS waives a required element. A biosimilar product candidate may be deemed
interchangeable with a prior approved product if it meets the higher hurdle of demonstrating that it can be expected to produce the same
clinical results as the reference product and, for products administered multiple times, the biological product candidate and the reference
biologic may be switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative
to exclusive use of the reference biologic. Complexities associated with the larger, and often more complex, structures of biologics,
as well as the process by which such products are manufactured, pose significant hurdles to implementation of the abbreviated approval
pathway that are still being resolved by FDA.
A
reference biologic is granted 12 years of exclusivity from the time of first licensure of the reference product, and no application for
a biosimilar can be submitted for four years from the date of licensure of the reference product. The first biological product candidate
submitted under the abbreviated approval pathway that is determined to be interchangeable with the reference product has exclusivity
against a finding of interchangeability for other biologics for the same condition of use for the lesser of (i) one year after first
commercial marketing of the first interchangeable biosimilar, (ii) 18 months after the first interchangeable biosimilar is approved if
there is no patent challenge, (iii) 18 months after resolution of a lawsuit over the patents of the reference biologic in favor of the
first interchangeable biosimilar applicant, or (iv) 42 months after the first interchangeable biosimilar’s application has been
approved if a patent lawsuit is ongoing within the 42 month period. At this time, it is unclear whether products deemed “interchangeable”
by FDA will, in fact, be readily substituted by pharmacies, which are governed by state pharmacy laws and regulations.
Healthcare
Regulation
Coverage,
Pricing, and Reimbursement
Our
ability to successfully commercialize any products for which we receive regulatory approval for commercial sale will depend, in part,
on the extent to which third-party payors provide coverage and establish adequate reimbursement levels for such products, and significant
uncertainty exists as to the coverage and reimbursement status of any products for which may we obtain regulatory approval. In the United
States, third-party payors include federal and state health care programs, private managed care providers, health insurers and other
organizations. The process for determining whether a third-party payor will provide coverage for a product may be separate from the process
for setting the price of a product or for establishing the reimbursement rate that such a payor will pay for the product. Third-party
payors may limit coverage to specific products on an approved list, also known as a formulary, which might not include all of the FDA-approved
products for a particular indication. Third-party payors are increasingly challenging the price, examining the medical necessity, and
reviewing the cost-effectiveness of medical products, therapies, and services, in addition to questioning their safety and efficacy.
We may need to conduct expensive pharmaco-economic studies in order to demonstrate the medical necessity and cost-effectiveness of our
products, in addition to the costs required to obtain FDA approvals. Our product candidates may not be considered medically necessary
or cost-effective. A payor’s decision to provide coverage for a product does not imply that an adequate reimbursement rate will
be approved. Further, one payor’s determination to provide coverage for a product does not assure that other payors will also provide
coverage for the product. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to
realize an appropriate return on our investment in product development.
The
marketability of any product candidates for which we receive regulatory approval for commercial sale may suffer if the government and
third-party payors fail to provide adequate coverage and reimbursement. In addition, emphasis on managed care in the United States has
increased and we expect will continue to increase the pressure on healthcare pricing. Coverage policies and third-party reimbursement
rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which we receive
regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.
Other
Healthcare Laws and Compliance Requirements
Although
we currently do not have any commercialized products, our current and future business operations may be subject to additional healthcare
regulation and enforcement by the federal government and by authorities in the states and foreign jurisdictions in which we conduct our
business. Such laws include, without limitation, state and federal anti-kickback, fraud and abuse, false claims, privacy and security,
price reporting and physician sunshine laws. Some of our pre-commercial activities are subject to some of these laws.
33
The
federal Anti-Kickback Statute makes it illegal for any person or entity, including
a prescription drug manufacturer or a party acting on its behalf to knowingly and willfully, directly or indirectly, solicit, receive,
offer, or pay any remuneration in cash or in kind that is intended to induce or reward the referral of business, including the purchase,
order, or lease of any item or service for which payment may be made under a federal healthcare program, such as Medicare or Medicaid.
The term “remuneration” has been broadly interpreted to include anything of value. The Anti-Kickback
Statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, formulary
managers and beneficiaries on the other.
Although
there are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution, the exceptions
and safe harbors are drawn narrowly. Practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases
or recommendations may be subject to scrutiny if they do not qualify for an exception or safe harbor. Failure to meet all of the requirements
of a particular applicable statutory exception or regulatory safe harbor does not make the conduct per se illegal under the Anti-Kickback
Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all its facts
and circumstances. Several courts have found that the Anti-Kickback Statute may be
violated if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare program business. In
addition, liability may be established without actual knowledge of the statute or specific intent to violate it. Violations of this law
are punishable by up to ten years in prison, and can also result in criminal fines, civil money penalties and exclusion from participation
in federal healthcare programs.
Moreover,
a claim including items or services resulting from a violation of the federal Anti-Kickback
Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act.
The
federal civil False Claims Act prohibits, among other things, individuals or entities from knowingly presenting, or causing to be presented,
a false or fraudulent claim for payment of government funds or knowingly making, using, or causing to be made or used, a false record
or statement material to an obligation to pay money to the government or knowingly concealing or knowingly and improperly avoiding, decreasing,
or concealing an obligation to pay money to the federal government. Persons and entities can be held liable under these laws if they
are deemed to “cause” the submission of false or fraudulent claims by, for example, providing inaccurate billing or coding
information to customers or promoting a product off-label. Many pharmaceutical and other healthcare companies have been investigated
and have reached substantial financial settlements with the federal government under the civil False Claims Act for a variety of alleged
improper marketing activities, including: providing free product to customers with the expectation that the customers would bill federal
programs for the product; providing sham consulting fees, grants, free travel and other benefits to physicians to induce them to prescribe
the company’s products; and inflating prices reported to private price publication services, which are used to set drug payment
rates under government healthcare programs. Penalties for federal civil False Claims Act violations may include up to three times the
actual damages sustained by the government, plus mandatory civil penalties of between $13,508 and $27,018 for each separate false claim,
and the potential for exclusion from participation in federal healthcare programs. In addition, although the federal False Claims Act
is a civil statute, False Claims Act violations may also implicate various federal criminal statutes.
The
healthcare fraud provisions of the Health Insurance Portability and Accountability Act (“HIPAA”) prohibit knowingly and willfully
executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third- party payors, knowingly
and willfully embezzling or stealing from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare
offense, and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious
or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Like the federal Anti-Kickback
Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed
a violation.
34
Many
states have analogous laws and regulations, such as: state anti-kickback and false claims laws that may apply to sales or marketing arrangements
and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers; laws
that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant
compliance guidance promulgated by the federal government or otherwise restrict payments that may be made to certain healthcare providers;
laws that require drug manufacturers to report information related to clinical trials or information related to payments and other transfers
of value to physicians and other healthcare providers or marketing expenditures; laws that restrict the ability of manufacturers to offer
co-pay support to patients for certain prescription drugs; and laws and local ordinances that require identification or licensing of
sales representatives.
HIPAA,
as amended by the Health Information Technology for Economic and Clinical Health Act (“HITECH”), and their implementing regulations,
mandates, among other things, the adoption of uniform standards for the electronic exchange of information in common healthcare transactions,
as well as standards relating to the privacy and security of individually identifiable health information, which require the adoption
of administrative, physical and technical safeguards to protect such information. Among other things, HITECH makes HIPAA’s security
standards directly applicable to business associates, defined as independent contractors or agents of covered entities that create, receive,
or obtain protected health information in connection with providing a service for or on behalf of a covered entity. HITECH also increased
the civil and criminal penalties that may be imposed against covered entities and business associates, and gave state attorneys general
new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney’s
fees and costs associated with pursuing federal civil actions. In addition, certain state laws govern the privacy and security of health
information in certain circumstances, some of which are more stringent than HIPAA and many of which differ from each other in significant
ways and may not have the same effect, thus complicating compliance efforts. Failure to comply with these laws, where applicable, can
result in the imposition of significant civil and/or criminal penalties.
The
U.S. federal Physician Payment Sunshine Act, implemented as the Open
Payments Program, requires manufacturers of drugs, devices, biologics, and medical supplies for which payment is available under Medicare,
Medicaid or the Children’s Health Insurance Program (with certain exceptions)
to report annually to CMS information related to direct or indirect payments and other transfers of value to physicians and teaching
hospitals (and certain other practitioners as of 2022), as well as ownership and investment interests held in the company by physicians
and their immediate family members.
Because
we intend to commercialize products that could be reimbursed under a federal health care program and other governmental healthcare programs,
we intend to develop a comprehensive compliance program that establishes internal control to facilitate adherence to the rules and program
requirements to which we will or may become subject. Although the development and implementation of compliance programs designed to establish
internal control and facilitate compliance can mitigate the risk of investigation, prosecution, and penalties assessed for violations
of these laws, the risks cannot be entirely eliminated.
If
our operations are found to be in violation of any of such laws or any other governmental regulations that apply to us, we may be subject
to penalties, including, without limitation, administrative, civil and criminal penalties, damages, fines, disgorgement, contractual
damages, reputational harm, diminished profits and future earnings, the curtailment or restructuring of our operations, exclusion from
participation in federal and state healthcare programs and individual imprisonment, any of which could adversely affect our ability to
operate our business and our financial results.
Health
Care Reform
In
the United States and some foreign jurisdictions, there have been, and continue to be, legislative and regulatory changes and proposed
changes regarding the healthcare system that could prevent or delay marketing approval of product candidates, restrict or regulate post-approval
activities, and affect the ability to profitably sell product candidates for which marketing approval is obtained. Among policy makers
and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated
goals of containing healthcare costs, improving quality and/or expanding access. In the United States, the pharmaceutical industry has
been a particular focus of these efforts and has been significantly affected by major legislative initiatives.
For
example, the Affordable Care Act (“ACA”)
substantially changed the way healthcare is financed by both the government and private insurers, and significantly impacts the U.S.
pharmaceutical industry. The ACA contains provisions that may reduce the profitability of drug products through increased rebates for
drugs reimbursed by Medicaid programs, extension of Medicaid rebates to Medicaid managed care plans, mandatory discounts for certain
Medicare Part D beneficiaries, and annual fees based on
pharmaceutical companies’ share of sales to federal health care programs. The ACA made several changes to the Medicaid
Drug Rebate Program, including increasing pharmaceutical manufacturers’ rebate liability by raising the minimum basic Medicaid
rebate. The ACA also expanded the universe of Medicaid utilization subject to drug rebates by requiring pharmaceutical manufacturers
to pay rebates on Medicaid managed care utilization and by enlarging the population potentially eligible for Medicaid drug benefits.
35
There
have been judicial challenges to certain aspects of the ACA, as well as efforts by Congress to modify, and by agencies to alter the implementation
of, certain aspects of the ACA. For example, Congress eliminated the tax penalty for failure to comply with the ACA’s individual
mandate to carry health insurance. Further, the Bipartisan Budget Act of 2018, among other things, amended the ACA to increase from 50
percent to 70 percent the point-of-sale discount that is owed by pharmaceutical manufacturers who participate in Medicare
Part D to close the coverage gap in most Medicare drug plans, commonly referred to as the donut
hole (this existing coverage gap program will be sunset by the Inflation Reduction Act beginning in 2025 and replaced with a new manufacturer
discount program).
It
is possible that the ACA, as currently enacted or as may be amended in the future, as well as other healthcare reform measures, including
those that may be adopted in the future, may result in more rigorous coverage criteria, and less favorable payment methodologies, or
other downward pressure on coverage and payment and the price that we receive for any approved product. Any reduction in reimbursement
or restriction on coverage under Medicare or other federal health care programs may result in a similar reduction or restriction by private
payors.
Other
legislative changes have been proposed and adopted in the U.S. since the ACA was enacted. For example, the Inflation Reduction Act introduces
several changes to the Medicare Part D benefit, including
a limit on annual out-of-pocket costs and a change in manufacturer liability under the program which could negatively affect the profitability
of our product candidates. The IRA sunsets the current Part D coverage gap discount program starting
in 2025 and replaces it with a new manufacturer discount program. Failure to pay a discount under this new program will be subject to
a civil monetary penalty. In addition, the IRA establishes a Medicare Part
B inflation rebate scheme effective January 2023 and a Medicare Part
D inflation rebate scheme effective October 2022, under which, generally speaking, manufacturers will owe rebates if the price of a Part
B or Part D drug increases faster than the pace of inflation. Failure to timely pay a Part
B or D inflation rebate is subject to a civil monetary penalty. The IRA also creates a drug price negotiation
program under which the prices for Medicare units of certain high Medicare spend drugs and biologicals without generic or biosimilar
competition will be capped by reference to, among other things, a specified non-federal average manufacturer price starting in 2026.
Failure to comply with requirements under the drug price negotiation program is subject to an excise tax and/or a civil monetary penalty.
Congress continues to examine various policy proposals that may result in pressure on the prices of prescription drugs with respect to
the government health benefit programs and otherwise. The IRA or other legislative changes could impact the market conditions for our
product candidates.
In
general, there has been heightened governmental scrutiny over the manner in which drug manufacturers set prices for their commercial
products, which has resulted in several Congressional inquiries and proposed and enacted
federal and state legislation designed to, among other things, bring more transparency to drug product pricing, review the relationship
between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. At the
state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological
product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing
cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.
Privacy
We
may also be subject to federal, state, national and international laws and regulations governing the privacy and security of health-related
and other personal data we collect and maintain (e.g., Section 5 of the Federal Trade Commission Act, the California
Privacy Rights Act, and the EU’s General Data Protection Regulation (the “GDPR”)). The GDPR, for example, imposes restrictions
on the processing (e.g., collection, use, or disclosure) of personal data in the EU and also imposes strict restrictions on the transfer
of personal data out of the EU to the United States. These laws and regulations are evolving and subject to interpretation and may impose
limitations on our activities or otherwise adversely affect our business. In addition, state laws govern the privacy and security of
health information in specified circumstances, many of which differ from each other in significant ways and may not have the same effect,
thus complicating compliance efforts.
If
we or our third party partners fail to comply or are alleged to have failed to comply with these or other applicable data protection
and privacy laws and regulations, or if we were to experience a data breach involving personal data, we could be subject to government
enforcement actions or private lawsuits. Any associated claims, inquiries, or investigations or other government actions could lead to
unfavorable outcomes that have a material impact on our business including through significant penalties or fines, monetary judgments
or settlements including criminal and civil liability for us and our officers and directors, increased compliance costs, delays or impediments
in the development of new products, negative publicity, increased operating costs, diversion of management time and attention, or other
remedies that harm our business, including orders that we modify or cease existing business practices.
