Recent
Developments
In
December 2024 the Company announced that it was in the process of exploring and reviewing strategic alternatives on an expedited basis
in order to preserve the Company’s cash, including a potential transaction with investor David Lazar of Activist Investing, LLC,
or “Lazar”. The Company’s Board of Directors reviewed a range of appropriate strategies to realize value from its assets.
The Board directed management to reduce operating costs, which included the liquidation of the Company’s wholly owned United Kingdom
subsidiary Cyclacel Limited, or Subsidiary, while such alternatives were being explored. On January 2, 2025 the Company entered into
a securities purchase agreement with investor Lazar, pursuant to which he agreed to purchase from the Company 1,000,000 shares of Series
C Convertible Preferred Stock and 2,100,000 shares of Series D Convertible Preferred Stock of Cyclacel at a purchase price of $1.00 per
share for aggregate gross proceeds of $3.1 million, subject to the terms and conditions of the Agreement. The proceeds of the transaction
will be used to settle outstanding liabilities of the Company and other general corporate and operating purposes.
On
January 31, 2025, the creditors voluntary liquidation of Cyclacel Limited was announced in the London Gazette, one of the official public
records of the government of the United Kingdom. As part of the Company’s efforts to reduce operating costs it has determined to
focus on the development of the plogo clinical program only. On March 10, 2025, the Company entered into an Agreement for the Sale and
Purchase of certain assets related to plogo with Cyclacel Limited and the joint liquidator. Therefore, fadraciclib, the Subsidiary’s
other drug development program, is being marketed for sale by the joint liquidator through Hilco Appraisals Limited, a firm of professional
valuation agents and will no longer be part of the assets of the Company as of January 2025.
With
the commencement of the liquidation of the Subsidiary, the Company will no longer be considered to have control over the Subsidiary and
the financial results of the Subsidiary will be deconsolidated from those of the Company. The deconsolidation, which is anticipated to
increase stockholders’ equity by approximately $5.0 million, will be reported in the Company’s Form 10-Q for the three months
ended March 31, 2025.

General
We
are a clinical-stage biopharmaceutical company working to develop innovative cancer medicines based on cell cycle, epigenetics and mitosis
biology. We are a pioneer company in the field of cancer cell cycle biology with a vision to improve patient healthcare by translating
insights in cancer biology into medicines that can overcome resistance and ultimately increase a patient’s overall survival.
The
epigenetic/anti-mitotic program is evaluating plogo, a PLK1 inhibitor, in solid tumors and hematological malignancies. Our strategy is
to build a diversified biopharmaceutical business based on a pipeline of novel drug candidates addressing oncology and hematology indications.
We
have retained rights to commercialize our clinical development candidates and our business objective is to enter into selective partnership
arrangements with these programs. Substantially all our efforts to date have been devoted to performing research and development, conducting
clinical trials, developing and acquiring intellectual property, raising capital and recruiting and training personnel.
As
part of the Company’s efforts to reduce operating costs, it has determined to focus on the development of plogo only.
Cell
Cycle Control Biology
Polo
Kinases and other mitotic kinases were first discovered in fruit flies by our former Chief Scientist, Professor David Glover, PhD. PLK1
is a serine/threonine kinase playing a central role in cell division, or mitosis. In particular, PLK1 regulates mitotic entry, spindle
formation, mitotic exit and cytokinesis and is an important regulator of the DNA damage checkpoint. Cancer cells are much more sensitive
to PLK1 depletion than normal cells with intact cell cycle checkpoints. Inhibiting PLK1 blocks proliferation by prolonged mitotic arrest
followed by onset of cancer cell death. The lead drug in our anti-mitotic program is plogosertib, or plogo (formerly known as CYC140).
Clinical
Development Pipeline
Our
pipeline of innovative medicines aims to provide safe and effective anticancer treatment options to patients combined with the convenience
of oral administration. Our preclinical and clinical studies suggests that daily dosing by the oral route is a preferred strategy for
both our drugs. We also conducted certain early clinical studies using intravenous (“i.v.”) administration. The aim of the
current streamlined studies is to assess safety and identify signals of clinical activity which may lead to registration-enabling outcomes.

Polo-Like-Kinase
inhibitor — Plogosertib
In
our Polo-like Kinase, or PLK, inhibitor program, we have discovered potent and selective small molecule inhibitors of PLK1. Polo Kinase
was discovered by Professor David Glover, our former Chief Scientist.
PLK1
is a serine/threonine kinase with a central role in cell division, or the mitotic phase of the cell cycle, and is an important regulator
of the DNA damage checkpoint. PLK1 over-expressing tumors include colorectal, esophageal, gastric, leukemia, lung, lymphoma, ovarian
and squamous cell cancers, as well as MYC amplified cancers including breast. Recent data with another PLK1 inhibitor in clinical development,
suggest that PLK1 inhibition may be effective in KRAS-mutated metastatic colorectal cancer.
Plogo
is a novel, small molecule, selective, PLK1 inhibitor which has demonstrated an epigenetic mechanism, potent and selective target inhibition
(PLK1 IC50 approximately 3 nM) and impressive efficacy in human tumor xenografts at non-toxic doses. Plogo has improved pharmaceutical
properties over earlier, clinical stage, PLK inhibitors. Our translational biology program supports the development of plogo in solid
tumor and hematological malignancy indications.
Clinical
development
Phase
1/2 Study in advanced solid tumors and lymphomas (CYC140-101, orally dosed)
This
open-label Phase 1/2 registration-directed study uses a streamlined design and initially seeks to determine the RP2D for single-agent
oralplogo in a dose escalation stage. Once RP2D has been established, the study will enter into proof-of-concept, cohort stage, using
a Simon 2-stage design. In this stage plogo will be administered to patients in up to seven mechanistically relevant cohorts including
patients with bladder, breast, colorectal (including KRAS mutant), hepatocellular and biliary tract, and lung cancers (both small cell
and non-small cell), as well as lymphomas. An additional basket cohort will enroll patients with biomarkers relevant to the drug’s
mechanism, including MYC amplified tumors. The protocol allows for expansion of individual cohorts based on response which may allow
acceleration of the clinical development and registration plan for plogo.
Fifteen
patients have been treated at the first five dose escalation levels with no dose limiting toxicities observed. Stable disease has been
observed in pretreated patients with gastrointestinal, lung, and ovarian cancers. A new, alternative salt, oral formulation of plogo
with improved bioavailability is under development.

Published
preclinical data
Preclinical
data presented at the 2016 28th EORTC-NCI-AACR Molecular Targets and Cancer Therapeutics Symposium and at the 2017 Annual Meeting of
the American Association of Cancer Research demonstrated the therapeutic potential of plogo as a targeted anti-cancer agent. The data
demonstrated that plogo is a selective PLK1 inhibitor which is highly active against both solid and liquid cancer models, preferentially
induces growth inhibition and cell death in malignant versus non-malignant cells.
Treatment
of proliferating cells with plogo resulted in reduced phosphorylation of the PLK1 substrate phospho-nucleophosmin, accumulation of cells
in mitosis and an increase in the proportion of mitotic cells with monopolar spindles, which are all features consistent with PLK1 inhibition.
In a cell line panel derived from esophageal cancer and various non-malignant solid tissues, plogo was preferentially cytotoxic to malignant
cells. Malignant cells which are sensitive to plogo undergo complete growth inhibition and induction of cell death in response to treatment.
In contrast, non-malignant cells are only temporarily arrested and normal cell cycle transit is restored.
Business
Strategy
Our
clinical development strategy is focused on our program in epigenetics/mitosis control biology. As part of the Company’s efforts
to reduce operating costs it has determined to focus on the development of the plogo clinical program only. Fadraciclib, the Subsidiary’s
other drug development program, is being marketed for sale by the joint liquidators through Hilco Appraisals Limited, a firm of professional
valuation agents and will no longer be part of the assets of the Company as of January 2025. We have retained worldwide rights to commercialize
plogo.
Focus
on the cell cycle and cancer
Our
core area of expertise is in cell cycle biology and our senior management team has extensive experience in research, preclinical and
clinical development and sales and marketing. The novel, mechanism-targeted cell cycle drugs we are developing are designed to be highly
selective in comparison to conventional chemotherapies, potentially inducing death in cancer cells while sparing most normal cells which
may give rise to fewer side-effects.
Thus,
we believe that we are well placed to exploit the significant opportunities that this area offers for new drug discovery and development.
Develop
anticancer drug candidates in all phases of the cell cycle and multiple compounds for particular cell cycle targets
Targeting
a broad development program focused on multiple phases of the cell cycle allows us to minimize risk while maximizing the potential for
success, and also to develop products that are complementary to one another.
Enter
into partnering arrangements selectively, while developing our own sales and marketing capability
We
currently retain virtually all marketing rights to the compounds associated with our clinical-stage drug programs. To optimize our commercial
return, we intend to enter into selected partnering arrangements and to retain co-promotion rights as appropriate. Generally we plan
to develop compounds through the Phase 2 proof-of-efficacy stage before seeking a partner. We may enter into partnering arrangements
earlier than Phase 2 proof-of-concept trials where appropriate, or in connection with drug programs outside our core competency in oncology.
Licenses
Some
of our programs are based on technology licensed from others. Our breach of an existing license or failure to obtain a license to technology
required to develop, test and commercialize our products may seriously harm our business. In March 2023, we terminated our license agreement
with Daiichi Sankyo Co., Ltd. for patents and patent applications covering sapacitabine for commercial reasons.

Patents and Proprietary Rights
As
of December 31, 2024, we owned 2 patent granted in the United States, 2 granted by the European Patent Office, or EPO, and 6 granted
in other countries worldwide. We owned 2 patent applications filed in the United States, 2 filed at the EPO and 16 filed in other countries
worldwide.
As
of March 26, 2025, we have 2 patents granted in the United States, 1 granted by the European Patent Office, or EPO, and 6 granted in
other countries worldwide. We have 2 patent applications filed in the United States, 2 filed at the EPO and 16 filed in other countries
worldwide.
Intellectual
Property Strategy
We
consider intellectual property rights to be vital and use a variety of methods to secure, protect and evaluate these rights. These methods
include ownership and enforcement of patent rights, patent applications, license agreements with third parties, invention assignment,
confidentiality and non-compete agreements with key employees and consultants, material transfer agreements, and trademark protection.
We
give priority to obtaining substance of matter claims in the United States, the EPO, Japan and other important markets if such protection
is available. We prefer composition of matter claims because they provide us with rights to the compounds themselves, and not merely
a particular use. In addition to composition of matter claims, we seek coverage for solid state forms, polymorphic and crystalline forms,
medical uses, combination therapies, specific regimens, pharmaceutical forms of our compounds and synthetic routes where available and
appropriate. Claims covering combination therapies, specific regimens and pharmaceutical forms can be valuable because the therapeutic
effect of pharmaceuticals used in the anticancer field is often enhanced when individual therapeutics are used in particular combinations
or dosed in a certain way. The availability of protection in these areas can, however, vary from jurisdiction to jurisdiction and combination
claims are particularly difficult to obtain for many inventions.
Since
publications in scientific or patent literature often lag behind actual discoveries, we are not certain of being first to make the inventions
covered by each of our pending patent applications or the first to file those patent applications. Generally, patent applications are
maintained in secrecy for a period of 18 months or more, which increases the uncertainty we face. Moreover, the patent positions of biotechnology
and pharmaceutical companies are highly uncertain and involve complex legal and factual questions. As a result, we cannot predict the
breadth of claims allowed in biotechnology and pharmaceutical patents, or their enforceability. Third parties or competitors may challenge
or circumvent our patents or patent applications, if issued. Because of the extensive time required for development, testing and regulatory
review of a potential product, it is possible that before we commercialize any of our products, any related patent may expire, or remain
in existence for only a short period following commercialization, thus reducing any advantage of the patent and the commercial opportunity
of the product.
If
patents are issued to others containing valid claims that cover our compounds or their manufacture or use or screening assays related
thereto, we may be required to obtain licenses to these patents or to develop or obtain alternative technology. We are aware of several
published patent applications, and understand that others may exist, that could support claims that, if granted and held valid, would
cover various aspects of our developmental programs, including in some cases particular uses of our drug candidate plogo, or other therapeutic
candidates, or substances, processes and techniques that we use in the course of our research and development and manufacturing operations.
In
addition, we understand that other applications and patents exist relating to potential uses of plogo which are not part of our
current clinical programs for those compounds. Although we intend to continue to monitor the pending applications, it is not
possible to predict whether these claims will ultimately be allowed or if they were allowed what their breadth would be. In
addition, we may need to commence litigation to enforce any patents issued to us or to determine the scope and validity of
third-party proprietary rights. For example, in one case we opposed a European patent relating to human aurora kinase and the patent
was finally revoked (no appeal was filed). Litigation would create substantial costs. We are aware that other patents exist that
claim substances, processes, techniques and methods of use, which, if held valid, could potentially restrict the scope of our
research, development or manufacturing operations. If competitors prepare and file patent applications in the United States that
claim technology that we also claim, we may have to participate in interference proceedings in the United States Patent and
Trademark Office to determine which invention has priority. These proceedings could result in substantial costs, even if the
eventual outcome is favorable to us. An adverse outcome in litigation could subject us to significant liabilities to third parties
and require us to seek licenses of the disputed rights from third parties or to cease using the technology, even a therapeutic
product, if such licenses are unavailable or too expensive.

Issued
patents for plogo cover the United States, EPO and six other countries.
Manufacturing
We
have no in-house manufacturing capabilities and have no current plans to establish manufacturing facilities for significant clinical
or commercial production. We have no direct experience in manufacturing commercial quantities of any of our products, and we currently
lack the resources or capability to manufacture any of our products on a clinical or commercial scale. As a result, we are dependent
on corporate partners, licensees or other third parties for the manufacturing of clinical (and eventually commercial) scale quantities
of all of our products. We believe that this strategy will enable us to direct operational and financial resources to the development
of our product candidate rather than diverting resources to establishing a manufacturing infrastructure.
Government
Regulation
The
FDA and comparable regulatory agencies in state and local jurisdictions, as well as in foreign countries, impose substantial regulatory
requirements upon the clinical development, manufacture, marketing and distribution of drugs. These agencies and other federal, state
and local authorities regulate research and development activities and the testing, manufacture, quality control, import, export, safety,
efficacy, labeling, packaging, storage, distribution, record keeping, approval, advertising, promotion, marketing, post-approval monitoring,
and post-approval reporting of drug products, such as those we are developing. Along with our third-party contractors, we will be required
to navigate the various preclinical, clinical and commercial approval requirements of the governing regulatory agencies of the countries
in which we wish to conduct studies or seek approval or licensure of plogo or any of its product candidates. The process of obtaining
regulatory approvals and the subsequent compliance with appropriate federal, state, local, and foreign statutes and regulations require
the expenditure of substantial time and financial resources.
For
example, in the United States, the FDA regulates drugs under the Federal Food, Drug and Cosmetic Act and its implementing regulations.
The process required by the FDA before our drug candidates may be marketed in the United States generally involves the following:
● completion
of extensive nonclinical laboratory tests, which may include animal studies and formulation
studies, all performed in accordance with the FDA’s good laboratory practice, or GLP,
regulations;
● submission
to the FDA of an investigational new drug application, or IND, which must become effective
before clinical trials may begin and must be updated annually or when significant changes
are made;
● approval
by an Institutional Review Board (“IRB”) or ethics committee at each clinical
site before the trial is initiated at such sites;
● performance
of adequate and well-controlled clinical trials in accordance with good clinical practice,
or GCP, and other clinical-trial related regulations to establish the safety and efficacy
of the drug candidate for each proposed indication;
● preparation
and submission of a new drug application (“NDA”), to the FDA;
● a
determination by the FDA within 60 days of its receipt of an NDA to file the application
for review;
10
Table of Contents
● satisfactory
completion of an FDA Advisory Committee review, if applicable;
● satisfactory
completion of an FDA pre-approval inspection of the manufacturing facilities at which the
product is produced to assess compliance with current good manufacturing practice requirements,
or cGMP, regulations;
● potential
audit of selected clinical trial sites to assess compliance with GCP and the integrity of
the clinical data submitted in support of the NDA; and
● FDA
review and approval of the NDA to permit commercial marketing of the drug product for particular
approved indications for use in the United States.
This
testing and approval process requires substantial time, effort and financial resources, and we cannot be certain that any approvals for
our drug candidates will be granted on a timely basis, if at all.
Preclinical
development
Before
testing any drug product candidate, including plogo, our sole current product candidate, in humans, the product candidate must undergo
rigorous preclinical testing. Preclinical and other nonclinical tests generally include laboratory evaluation of product chemistry, formulation
and stability, as well as studies to evaluate toxicity in animals. The Consolidated Appropriations Act for 2023, signed into law on December
29, 2022, (P.L. 117-328) amended the FDCA and the Public Health Service Act to specify that nonclinical testing for drugs may, but is
not required to, include in vivo animal testing. According to the amended language, a sponsor may fulfill nonclinical testing requirements
by completing various in vitro assays (e.g., cell-based assays, organ chips, or micro-physiological systems), in silico studies (i.e.,
computer modeling), other human or nonhuman biology-based tests (e.g., bioprinting), or in vivo animal tests. The conduct of preclinical
studies is subject to federal regulations and requirements, including GLP regulations for safety/toxicology studies. Some long-term preclinical
testing, such as animal tests of reproductive adverse events and carcinogenicity, may continue after an IND for an investigational drug
candidate is submitted to the FDA and human clinical trials have been initiated.
The
results of preclinical tests, together with manufacturing information and analytical data, are submitted as part of an IND to the FDA.
An IND must become effective before human clinical trials may begin. The IND automatically becomes effective 30 days after receipt by
the FDA, unless the FDA, within the 30-day time period, issues a notice expressly authorizing the proposed trial to proceed or raises
concerns or questions about the adequacy or safety of the preclinical testing or the proposed conduct of the clinical trial, including
concerns that human research subjects will be exposed to unreasonable health risks. If FDA raises concerns or places the trial on clinical
hold, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. Our submission of an IND,
or those of our collaborators, may therefore not result in FDA authorization to commence a clinical trial. A separate submission to an
existing IND must also be made for each successive clinical trial conducted during product development. Further, an independent institutional
review board, or IRB, for each medical center proposing to conduct the clinical trial (or a central IRB) must review and approve the
plan for any clinical trial before such trial commences at that site and the designated IRB must monitor the clinical trial until completed.
The FDA or the clinical trial sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects
or patients are being exposed to an unacceptable health risk. Clinical testing also must satisfy extensive good clinical practice, or
GCP, requirements, including those relating to informed consent.
Clinical
Trials
For
purposes of an NDA submission, clinical trials are typically conducted in the following three sequential phases, which may overlap:
Phase
1 : The clinical trials are initially conducted in a limited population to test the drug candidate for safety, dose tolerance,
absorption, metabolism, distribution and excretion in healthy humans. In the case of some products for severe or life-threatening
diseases, such as cancer, especially when the product may be too inherently toxic to ethically administer to healthy volunteers, the
initial human testing is often conducted in patients. Phase 1 clinical trials can be designed to evaluate the impact of the drug
candidate in combination with currently approved drugs.
11
Table of Contents
Phase
2: These clinical trials are generally conducted in a limited patient population to identify possible adverse effects and safety
risks, to evaluate preliminary efficacy of the drug candidate for specific targeted indications and to determine dose tolerance and optimal
dosage. Multiple Phase 2 clinical trials may be conducted by the sponsor to obtain information prior to beginning larger and more expensive
Phase 3 clinical trial.
Phase
3: These clinical trials are commonly referred to as pivotal clinical trials. If the Phase 2 clinical trials demonstrate that a dose
range of the drug candidate is effective and has an acceptable safety profile, Phase 3 clinical trials are then undertaken in large patient
populations to further evaluate dosage, to provide substantial evidence of clinical efficacy and to further test for safety in an expanded
and diverse patient population at multiple, geographically dispersed clinical trial sites. These trials are intended to establish the
overall risk-benefit ratio of the product candidate and provide, if appropriate, an adequate basis for product labeling. Phase 3 trials
typically include comparisons with placebo and/or other comparator treatments. The duration of treatment is often extended to mimic the
actual use of a product during marketing.
In
some cases, the FDA may condition approval of an NDA for a drug candidate on the sponsor’s agreement to conduct a Phase 4, which
includes additional clinical trials to further assess the drug’s safety and effectiveness after NDA approval.
In
the Consolidated Appropriations Act for 2023, Congress amended the FDCA to require sponsors of a Phase 3 clinical trial, or other “pivotal
study” of a new drug to support marketing authorization, to submit a diversity action plan for such clinical trial. The action
plan must include the sponsor’s diversity goals for enrollment, as well as a rationale for the goals and a description of how the
sponsor will meet them. A sponsor must submit a diversity action plan to FDA by the time the sponsor submits the trial protocol to the
agency for review. The FDA may grant a waiver for some or all of the requirements for a diversity action plan. It is unknown at this
time how the diversity action plan may affect Phase 3 trial planning and timing or what specific information FDA will expect in such
plans, but if FDA objects to a sponsor’s diversity action plan and requires the sponsor to amend the plan or take other actions,
it may delay trial initiation.
Progress
reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more frequently if unexpected
serious adverse events, or SAEs, occur. The FDA or the sponsor may suspend or terminate a clinical trial at any time on various grounds,
including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend
or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the clinical
protocol, GCP, or other IRB requirements or if the drug has been associated with unexpected serious harm to patients.
NDA
Submission and Review by the FDA
Assuming
successful completion of all required testing in accordance with all applicable regulatory requirements, the results of product development,
preclinical studies and clinical trials are submitted to the FDA as part of an NDA requesting approval to market the product for one
or more indications. The NDA must contain proof of the product candidate’s safety and substantial evidence of effectiveness for
its proposed indication or indications in the form of relevant data available from pertinent preclinical and clinical studies, including
negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry,
manufacturing, controls, and proposed labeling, among other things. In particular, a marketing application must demonstrate that the
manufacturing methods and quality controls used to produce the drug product are adequate to preserve the drug’s identity, strength,
quality, and purity. Data can come from company-sponsored clinical studies intended to test the safety and effectiveness of a use of
the product, or from a number of alternative sources, including studies initiated by investigators. FDA approval of an NDA must be obtained
before the corresponding drug may be marketed in the United States.
12
Table of Contents
The
FDA reviews all NDAs submitted to determine if they are substantially complete before it accepts them for filing and may request additional
information rather than accepting a submission for filing. The FDA must make a decision on accepting an NDA for filing within 60 days
of receipt and must inform the sponsor by the 74th day after the FDA’s receipt of the submission whether the application is sufficiently
complete to permit substantive review. The FDA may refuse to file any submission that it deems incomplete or not properly reviewable
at the time of submission and may request additional information. In this event, the marketing application must be resubmitted with the
additional information requested by the agency. The resubmitted application is also subject to review before the FDA accepts it for filing.
During
the review process, the FDA reviews the NDA to determine, among other things, whether the product is safe and effective and whether the
facility in which it is manufactured, processed, packed, or held meets standards designed to assure the product’s continued strength,
quality, and purity. The FDA may refer any NDA, including applications for novel drug candidates which present difficult questions of
safety or efficacy to an advisory committee to provide clinical insight on application review questions. Typically, an advisory committee
is a panel of independent experts, including clinicians and other scientific experts that reviews, evaluates and provides a recommendation
as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendation of an advisory
committee, but it considers such recommendations carefully when making final decisions on approval.
Under
the Pediatric Research Equity Act, or PREA, amendments to the FDCA, an NDA or supplement to an NDA must contain data that are adequate
to assess the safety and efficacy of the product candidate for the claimed indications in all relevant pediatric populations and to support
dosing and administration for each pediatric population for which the product is safe and effective. The FDA may grant deferrals for
submission of pediatric data or full or partial waivers. The PREA requires a sponsor that is planning to submit a marketing application
for a product that includes a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration
to submit an initial Pediatric Study Plan, or PSP, within sixty days of an end-of-Phase 2 meeting or, if there is no such meeting, as
early as practicable before the initiation of the Phase 3 or Phase 2/3 clinical trial. The initial PSP must include an outline of the
pediatric study or studies that the sponsor plans to conduct, including trial objectives and design, age groups, relevant endpoints and
statistical approach, or a justification for not including such detailed information, and any request for a deferral of pediatric assessments
or a full or partial waiver of the requirement to provide data from pediatric studies along with supporting information. The FDA and
the sponsor must reach an agreement on the PSP. A sponsor can submit amendments to an agreed upon initial PSP at any time if changes
to the pediatric plan need to be considered based on data collected from pre-clinical studies, early-phase clinical trials or other clinical
development programs.
If
regulatory approval of a product is granted, such approval is limited to the conditions of use (e.g., patient population, indication)
described in the application and may entail further limitations on the indicated uses for which such product may be marketed. For example,
the FDA may approve the NDA with a Risk Evaluation and Mitigation Strategy, or REMS, plan to mitigate risks, which 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. The FDA determines the requirement for a REMS, as well as the specific REMS provisions, on a case-by-case
basis. If the FDA concludes a REMS plan is needed, the sponsor of the NDA must submit a proposed REMS. The FDA will not approve an NDA
without a REMS, if one is required. The FDA also may condition approval on, among other things, changes to proposed labeling (e.g., adding
contraindications, warnings or precautions) or the development of adequate controls and specifications. Once approved, the FDA may withdraw
the product approval if compliance with pre- and post-marketing regulatory standards is not maintained or if problems occur after the
product reaches the marketplace. The FDA may require one or more Phase 4 post-market studies and surveillance to further assess and monitor
the product’s safety and effectiveness after commercialization and may limit further marketing of the product based on the results
of these post-marketing studies. After approval, some types of changes to the approved product, such as adding new indications, manufacturing
changes and additional labeling claims, are subject to further testing requirements and FDA review and approval. In addition, new government
requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could
delay or prevent regulatory approval of our products under development.

Table of Contents
Fast
Track, Priority Review, and Breakthrough Therapy Designations
A
sponsor may seek approval of its product candidate under programs designed to accelerate FDA’s review and approval of new drugs
and biological products that meet certain criteria. Specifically, new drugs and biological products are eligible for fast track designation
if they are intended to treat a serious or life-threatening condition and demonstrate the potential to address unmet medical needs for
the condition. Fast track designation provides increased opportunities for sponsor interactions with the FDA during preclinical and clinical
development, in addition to the potential for rolling review once a marketing application is filed, meaning that the FDA may consider
for review sections of the NDA or BLA on a rolling basis before the complete application is submitted, if the sponsor provides a schedule
for the submission of the sections of the application, the FDA agrees to accept the sections and determines that the schedule is acceptable,
and the sponsor pays any required user fees upon submission of the first section of the application. A fast track designated product
candidate may also qualify for accelerated approval (described below) or priority review, under which the FDA sets the target date for
FDA action on the NDA or BLA at six months after the FDA accepts the application for filing.
Priority
review is granted when there is evidence that the proposed product would be a significant improvement in the safety or effectiveness
of the treatment, diagnosis, or prevention of a serious condition. Significant improvement may be illustrated by evidence of increased
effectiveness in the treatment of a condition, elimination or substantial reduction of a treatment-limiting drug reaction, documented
enhancement of patient compliance that may lead to improvement in serious outcomes, or evidence of safety and effectiveness in a new
subpopulation. If criteria are not met for priority review, the application is subject to the standard FDA review period of 10 months
after FDA accepts the application for filing.
In
addition, a sponsor may seek FDA designation of its product candidate as a breakthrough therapy if the product candidate is intended,
alone or in combination with one or more other drugs or biologics, to treat a serious or life-threatening disease or condition and preliminary
clinical evidence indicates that the therapy may demonstrate substantial improvement over existing therapies on one or more clinically
significant endpoints, such as substantial treatment effects observed early in clinical development. Breakthrough therapy designation
provides all the features of fast track designation in addition to intensive guidance on an efficient development program beginning as
early as Phase 1, and FDA organizational commitment to expedited development, including involvement of senior managers and experienced
review and regulatory staff in a proactive, collaborative, cross-disciplinary review, where appropriate. A drug designated as breakthrough
therapy is also eligible for accelerated approval if the relevant criteria are met.
Even
if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for
qualification or decide that the time period for FDA review or approval will not be shortened. fast track, priority review and breakthrough
therapy designations do not change the scientific or medical standards for approval or the quality of evidence necessary to support approval
but may expedite the development or approval process.
Accelerated
Approval
In
addition, products studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful
therapeutic benefit over existing treatments may receive accelerated approval from the FDA and may be approved on the basis of adequate
and well-controlled clinical trials establishing that the drug product has an effect on a surrogate endpoint that is reasonably likely
to predict clinical benefit. The FDA may also grant accelerated approval for such a drug or biologic when it has an effect on an intermediate
clinical endpoint that can be measured earlier than an effect on irreversible morbidity or mortality, or IMM, and that is reasonably
likely to predict an effect on IMM or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition
and the availability or lack of alternative treatments. As a condition of approval, the FDA may require that a sponsor of a drug or biologic
receiving accelerated approval perform post-marketing clinical trials to verify and describe the predicted effect on IMM or other clinical
endpoint, and the product may be subject to expedited withdrawal procedures. Drugs and biologics granted accelerated approval must meet
the same statutory standards for safety and effectiveness as those granted traditional approval.

Table of Contents
The
accelerated approval pathway is usually contingent on a sponsor’s agreement to conduct, in a diligent manner, additional post-approval
confirmatory studies to verify and describe the product candidate’s clinical benefit. As a result, a product candidate approved
on this basis is subject to rigorous post-marketing compliance requirements, including the completion of Phase 4 or post-approval clinical
trials to confirm the effect on the clinical endpoint. Failure to conduct required post-approval studies, or to confirm the predicted
clinical benefit of the product during post-marketing studies, would allow the FDA to withdraw approval of the product. As part of the
Consolidated Appropriations Act for 2023, Congress provided FDA additional statutory authority to mitigate potential risks to patients
from continued marketing of ineffective drugs or biologics previously granted accelerated approval. Under the act’s amendments
to the FDCA, FDA may require the sponsor of a product granted accelerated approval to have a confirmatory trial underway prior to approval.
The sponsor must also submit progress reports on a confirmatory trial every six months until the trial is complete, and such reports
are published on FDA’s website. The amendments also give FDA the option of using expedited procedures to withdraw product approval
if the sponsor’s confirmatory trial fails to verify the claimed clinical benefits of the product.
All
promotional materials for product candidates being considered and approved under the accelerated approval program are subject to prior
review by the FDA.
Special
Protocol Assessment
If
a Phase 2 clinical trial is the subject of discussion at an end-of-Phase 2 meeting with the FDA, a sponsor may be able to request a Special
Protocol Assessment, or SPA, the purpose of which is to reach agreement with the FDA on the design of the Phase 3 clinical trial protocol
design and analysis that will form the primary basis of an efficacy claim. If such an agreement is reached, it will be documented and
made part of the administrative record, and it will be binding on the FDA and may not be changed unless the sponsor fails to follow the
agreed-upon protocol, data supporting the request are found to be false or incomplete, or the FDA determines that a substantial scientific
issue essential to determining the safety or effectiveness of the drug was identified after the testing began. Even if an SPA is agreed
to, approval of the NDA is not guaranteed because a final determination that an agreed-upon protocol satisfies a specific objective,
such as the demonstration of efficacy, or supports an approval decision, will be based on a complete review of all the data in the NDA.
Orphan
Drugs
Under
the Orphan Drug Act, the FDA may grant orphan drug designation to a drug intended to treat a rare disease or condition, defined as a
disease or condition with a patient population of fewer than 200,000 individuals in the United States, or a patient population greater
than 200,000 individuals in the United States and when there is no reasonable expectation that the cost of developing and making available
the drug in the United States will be recovered from sales in the United States for that drug. Orphan drug designation must be requested
before submitting a marketing application. After the FDA grants orphan drug designation, the generic identity of the therapeutic agent
and its potential orphan use are disclosed publicly by the FDA.
If
a drug product that has orphan drug designation subsequently receives the first FDA approval for a particular active ingredient for the
disease for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve
any other applications, including a full NDA, to market the same drug for the same indication for seven years, except in limited circumstances,
such as a showing of clinical superiority to the product with orphan product exclusivity or if FDA finds that the holder of the orphan
product exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan product to meet the needs
of patients with the disease or condition for which the drug was designated. Orphan product exclusivity does not prevent the FDA from
approving a different drug for the same disease or condition, or the same drug for a different disease or condition. Among the other
benefits of orphan drug designation are tax credits for certain research and a waiver of the NDA application user fee.

Patent
term restoration
Depending
upon the timing, duration and specifics of FDA approval of the use of our product candidate, some of our United States patents may be
eligible for limited patent term extension under the Hatch-Waxman Act. The Hatch-Waxman Act permits a patent restoration term of up to
five years as compensation for patent term lost during product development and the FDA regulatory review process. However, patent term
restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product candidate’s approval date.
The patent term restoration period is generally one half of the time between the effective date of an IND and the submission date of
an NDA, plus the time between the submission date of the NDA and the approval of that application, except that the review period is reduced
by any time during which the applicant failed to exercise due diligence. Only one patent applicable to an approved product candidate
is eligible for the extension and the application for extension must be made prior to expiration of the patent. The USPTO, in consultation
with the FDA, reviews and approves the application for any patent term extension or restoration. In the future, we intend to apply for
restorations of patent term for some of our currently owned or licensed patents to add patent life beyond their current expiration date,
depending on the expected length of clinical trials and other factors involved in the submission of the relevant NDA.
Post-approval
requirements
Following
approval of a new product, the manufacturer and the approved product are subject to pervasive and continuing regulation by the FDA, including,
among other things, monitoring and recordkeeping activities, reporting of adverse experiences with the product, product sampling and
distribution restrictions, complying with promotion and advertising requirements, which include restrictions on promoting drugs for unapproved
uses or patient populations (i.e., “off-label use”) and limitations on industry-sponsored scientific and educational activities.
The manufacturer and its products are also subject to similar post-approval requirements by regulatory authorities comparable to FDA
in jurisdictions outside of the United States where the products are approved. Although physicians may prescribe legally available products
for off-label uses, manufacturers may not market or promote such uses.
FDA
regulations require that products be manufactured in specific approved facilities and in accordance with cGMPs. The cGMP regulations
include requirements relating to organization of personnel, buildings and facilities, equipment, control of components and drug product
containers and closures, production and process controls, packaging and labeling controls, holding and distribution, laboratory controls,
records and reports and returned or salvaged products. The manufacturing facilities for our product candidate must meet applicable cGMP
requirements to the FDA’s or comparable foreign regulatory authorities’ satisfaction before any product is approved and our commercial
products can be manufactured. We rely, and expect to continue to rely, on third parties for the production of clinical (and ultimately
commercial) quantities of our products in accordance with cGMP regulations. These manufacturers must comply with cGMP regulations that
require, among other things, quality control and quality assurance, the maintenance of records and documentation and the obligation to
investigate and correct any deviations from cGMP. Manufacturers and other entities involved in the manufacture and distribution of approved
drugs are required to register their establishments with the FDA and certain state agencies and are subject to periodic prescheduled
or unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, manufacturers
must continue to expend time, money and effort in the area of production and quality control to maintain cGMP compliance. Future inspections
by the FDA and other regulatory agencies may identify compliance issues at the facilities of our CMOs that may disrupt production or
distribution or require substantial resources to correct. In addition, the discovery of conditions that violate these rules, including
failure to conform to cGMPs, could result in enforcement actions, and the discovery of problems with a product after approval may result
in restrictions on a product, manufacturer or holder of an approved NDA, including voluntary recall and regulatory sanctions as described
below.
16
Table of Contents
Once
an approval or clearance of a drug is granted, the 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 mandatory revisions to the approved labeling to add new safety information; imposition of post-market or
clinical trials to assess new safety risks; or imposition of distribution or other restrictions under a REMS program. Other potential
consequences include, among other things:
● restrictions
on the marketing or manufacturing of the product, complete withdrawal of the product from
the market or product recalls;
● fines,
warning letters or other enforcement-related letters or clinical holds on post-approval clinical
trials;
● refusal
of the FDA to approve pending marketing applications or supplements to approved marketing
authorizations, or suspension or revocation of product approvals;
● product
seizure or detention, or refusal to permit the import or export of products;
● injunctions
or the imposition of civil or criminal penalties; and
● consent
decrees, corporate integrity agreements, debarment, or exclusion from federal health care
programs; or mandated modification of promotional materials and labeling and the issuance
of corrective information.
In
addition, the distribution of prescription pharmaceutical products is subject to the Prescription Drug Marketing Act, or PDMA, which
regulates the distribution of drugs and drug samples at the federal level and sets minimum standards for the registration and regulation
of drug distributors by the states. Both the PDMA and state laws limit the distribution of prescription pharmaceutical product samples
and impose requirements to ensure accountability in distribution. Most recently, the Drug Supply Chain Security Act, or DSCSA, was enacted
with the aim of building an electronic system to identify and trace certain prescription drugs distributed in the United States. The
DSCSA mandates phased-in and resource-intensive obligations for pharmaceutical manufacturers, wholesale distributors, and dispensers
over a 10-year period that was initially expected to culminate in November 2023. In August 2023, the FDA announced “a 1-year stabilization
period to accommodate additional time” needed by pharmaceutical supply chain stakeholders. Since then, the deadline has been pushed
further with an additional year into 2025. The DSCSA’s new 2025 deadline for manufacturers and repackagers is May 27, 2025. From
time to time, new legislation and regulations may be implemented that could significantly change the statutory provisions governing the
approval, manufacturing and marketing of products regulated by the FDA. It is impossible to predict whether further legislative or regulatory
changes will be enacted, whether FDA regulations, guidance or interpretations will be changed or what the impact of such changes, if
any, may be.
Other
U.S. health care laws and regulations
The
majority of states also have statutes or regulations similar to the aforementioned federal laws, some of which are broader in scope and
apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payor.
Some state laws require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines,
or the relevant compliance guidance promulgated by the federal government, in addition to requiring drug manufacturers to report information
related to payments to physicians and other health care providers or marketing expenditures to the extent that those laws impose requirements
that are more stringent than the Physician Payments Sunshine Act. State and foreign laws also govern the privacy and security of health
information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus
complicating compliance efforts.
17
Table of Contents
Because
of the breadth of these laws and the narrowness of their exceptions and safe harbors, it is possible that business activities can be
subject to challenge under one or more of such laws. The scope and enforcement of each of these laws is uncertain and subject to rapid
change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulations. Federal
and state enforcement bodies have recently increased their scrutiny of interactions between healthcare companies and healthcare providers,
which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry.
Ensuring
that business arrangements with third parties comply with applicable healthcare laws and regulations is costly and time consuming. If
business operations are found to be in violation of any of the laws described above or any other applicable governmental regulations
a pharmaceutical manufacturer may be subject to penalties, including civil, criminal and administrative penalties, damages, fines, disgorgement,
individual imprisonment, exclusion from governmental funded healthcare programs, such as Medicare and Medicaid, contractual damages,
reputational harm, diminished profits and future earnings, additional reporting obligations and oversight if subject to a corporate integrity
agreement or other agreement to resolve allegations of non-compliance with these laws, and curtailment or restructuring of operations,
any of which could adversely affect a pharmaceutical manufacturer’s ability to operate its business and the results of its operations.
Regulation
outside of the United States
In
addition to regulations in the United States, we will be subject to a variety of foreign regulations governing clinical trials and commercial
sales and distribution of our products outside of the United States. Whether or not we obtain FDA approval for a product candidate, we
must obtain approval by the comparable regulatory authorities of foreign countries or economic areas, such as the 28-member European
Union, before we may commence clinical trials or market products in those countries or areas. The approval process and requirements governing
the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly between countries and jurisdictions and can
involve additional testing and additional administrative review periods. The time required to obtain approval in other countries and
jurisdictions might differ from and be longer than that required to obtain FDA approval. Regulatory approval in one country or jurisdiction
does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country or jurisdiction
may negatively impact the regulatory process in others.
European
Union drug development, review and approval
In
the European Union, our product candidate also may be subject to extensive regulatory requirements. As in the United States, medicinal
products can be marketed only if a marketing authorization from the competent regulatory agencies has been obtained. Similar to the United
States, the various phases of pre-clinical and clinical research in the European Union are subject to significant regulatory controls.
The
Clinical Trials Directive 2001/20/EC, the Directive 2005/28/EC on GCP, and the related national implementing provisions of the individual
EU Member States govern the system for the approval of clinical trials in the European Union. Under this system, an applicant must obtain
prior approval from the competent national authority of the EU Member States in which the clinical trial is to be conducted. Furthermore,
the applicant may only start a clinical trial at a specific study site after the competent ethics committee has issued a favorable opinion.
The clinical trial application must be accompanied by, among other documents, an IMPD (the Common Technical Document) with supporting
information prescribed by Directive 2001/20/EC, Directive 2005/28/EC, and where relevant the implementing national provisions of the
individual EU Member States and further detailed in applicable guidance documents. All suspected unexpected serious adverse reactions
to the investigated drug that occur during the clinical trial have to be reported to the competent national authority and the Ethics
Committee of the Member State where they occurred.
Under
the EU’s new Clinical Trials Regulation, which took effect in January 2022, there will be a centralized application procedure
where one EU Member State’s competent authority takes the lead in reviewing part I of the application, which contains
scientific and medicinal product documentation, and the other national authorities only have limited involvement. Part II, which
contains the national and patient-level documentation, will be assessed individually by each EU Member State. Strict deadlines have
been established for the assessment of clinical trial applications. The role of the relevant ethics committees in the assessment
procedure will continue to be governed by the national law of the competent EU Member State. Any substantial changes to the trial
protocol or other information submitted with the CTA must be notified to or approved by the relevant competent authorities and
ethics committees. Medicines used in clinical trials must be manufactured in accordance with good manufacturing practices. Other
national and EU-wide regulatory requirements may also apply. Currently, the extent to which clinical trials will be governed by the
Clinical Trials Regulation will depend on when the clinical trial is initiated or on the duration of an ongoing trial. As of January
2023, all new clinical trials must comply with the Clinical Trials Regulation. In addition, any clinical trial that was already
under way as of January 1, 2023 and continues for more than three years from the day on which the Clinical Trials Regulation becomes
applicable (i.e., January 31, 2025), the Clinical Trials Regulation will at that time begin to apply to the clinical
trial.

Table of Contents
To
obtain a marketing authorization of a drug in the European Union, we may submit marketing authorization applications, or MAA, either
under the so-called centralized or national authorization procedures.
Centralized
procedure
The
centralized procedure provides for the grant of a single marketing authorization following a favorable opinion by the European Medicines
Agency, or EMA, that is valid in all EU member states, as well as Iceland, Liechtenstein and Norway. The centralized procedure is compulsory
for medicines produced by specified biotechnological processes, products designated as orphan medicinal products, advanced-therapy medicines
(such as gene-therapy, somatic cell-therapy or tissue-engineered medicines) and products with a new active substance indicated for the
treatment of specified diseases, such as HIV/AIDS, cancer, diabetes, neurodegenerative disorders or autoimmune diseases and other immune
dysfunctions and viral diseases. The centralized procedure is optional for products that represent a significant therapeutic, scientific
or technical innovation, or whose authorization would be in the interest of public health. Under the centralized procedure the maximum
timeframe for the evaluation of an MAA by the EMA is 210 days, excluding clock stops, when additional written or oral information is
to be provided by the applicant in response to questions asked by the Committee for Medicinal Products for Human Use, or the CHMP. Accelerated
assessment might be granted by the CHMP in exceptional cases, when a medicinal product is expected to be of a major public health interest,
particularly from the point of view of therapeutic innovation. The timeframe for the evaluation of an MAA under the accelerated assessment
procedure is 150 days, excluding stop-clocks.
National
authorization procedures
There
are also two other possible routes to authorize medicinal products in several EU countries, which are available for investigational medicinal
products that fall outside the scope of the centralized procedure:
Decentralized
procedure. Using the decentralized procedure, an applicant may apply for simultaneous authorization in more than one EU country of medicinal
products that have not yet been authorized in any EU country and that do not fall within the mandatory scope of the centralized procedure.
Mutual
recognition procedure. In the mutual recognition procedure, a medicine is first authorized in one EU Member State, in accordance with
the national procedures of that country. Following this, further marketing authorizations can be sought from other EU countries in a
procedure whereby the countries concerned agree to recognize the validity of the original, national marketing authorization.
Under
the above described procedures, before granting the marketing authorization, the EMA or the competent authorities of the Member States
of the EEA make an assessment of the risk-benefit balance of the product on the basis of scientific criteria concerning its quality,
safety and efficacy.
Conditional
approval
In
specific circumstances, E.U. legislation (Article 14(7) Regulation (EC) No 726/2004 and Regulation (EC) No 507/2006 on Conditional
Marketing Authorizations for Medicinal Products for Human Use) enables applicants to obtain a conditional marketing authorization
prior to obtaining the comprehensive clinical data required for an application for a full marketing authorization. Such conditional
approvals may be granted for product candidates (including medicines designated as orphan medicinal products) if (1) the
risk-benefit balance of the product candidate is positive, (2) it is likely that the applicant will be in a position to provide the
required comprehensive clinical trial data, (3) the product fulfills unmet medical needs and (4) the benefit to public health of the
immediate availability on the market of the medicinal product concerned outweighs the risk inherent in the fact that additional data
are still required. A conditional marketing authorization may contain specific obligations to be fulfilled by the marketing
authorization holder, including obligations with respect to the completion of ongoing or new studies, and with respect to the
collection of pharmacovigilance data. Conditional marketing authorizations are valid for one year, and may be renewed annually, if
the risk-benefit balance remains positive, and after an assessment of the need for additional or modified conditions or specific
obligations. The timelines for the centralized procedure described above also apply with respect to the review by the CHMP of
applications for a conditional marketing authorization.

Table of Contents
European
Union regulatory exclusivity
In
the European Union, new products authorized for marketing (i.e., reference products) qualify for eight years of data exclusivity and
an additional two years of market exclusivity upon marketing authorization. The data exclusivity period prevents generic or biosimilar
applicants from relying on the pre-clinical and clinical trial data contained in the dossier of the reference product when applying for
a generic or biosimilar marketing authorization in the European Union during a period of eight years from the date on which the reference
product was first authorized in the European Union. The market exclusivity period prevents a successful generic or biosimilar applicant
from commercializing its product in the EU until ten years have elapsed from the initial authorization of the reference product in the
EU. The ten-year market exclusivity period can be extended to a maximum of eleven years if, during the first eight years of those ten
years, the marketing authorization holder obtains an authorization for one or more new therapeutic indications which, during the scientific
evaluation prior to their authorization, are held to bring a significant clinical benefit in comparison with existing therapies.
European
Union orphan designation and exclusivity
The
criteria for designating an orphan medicinal product in the European Union, are similar in principle to those in the United States.
Under Article 3 of Regulation (EC) 141/2000, a medicinal product may be designated as orphan if (1) it is intended for the
diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition;
(2) either (a) such condition affects no more than five in 10,000 persons in the European
Union when the application is made, or (b) the product, without the benefits derived from orphan status, would not generate
sufficient return in the European Union to justify investment; and (3) there exists no satisfactory method of diagnosis, prevention
or treatment of such condition authorized for marketing in the European Union, or if such a method exists, the product will be of
significant benefit to those affected by the condition, as defined in Regulation (EC) 847/2000. Orphan medicinal products are
eligible for financial incentives such as reduction of fees or fee waivers and are, upon grant of a marketing authorization,
entitled to ten years of market exclusivity for the approved therapeutic indication. The application for orphan designation must be
submitted before the application for marketing authorization. The applicant will receive a fee reduction for the marketing
authorization application if the orphan designation has been granted, but not if the designation is still pending at the time the
marketing authorization is submitted. Orphan designation does not convey any advantage in, or shorten the duration of, the
regulatory review and approval process.
The
ten-year market exclusivity in the European Union may be reduced to six years if, at the end of the fifth year, it is established that
the product no longer meets the criteria for orphan designation, for example, if the product is sufficiently profitable not justifying
maintenance of market exclusivity. Additionally, marketing authorization may be granted to a similar product for the same indication
at any time if:
● the
second applicant can establish that its product, although similar, is safer, more effective
or otherwise clinically superior;
● the
applicant consents to a second orphan medicinal product application; or
● the
applicant cannot supply enough orphan medicinal product.
20
Table of Contents
PRIME
designation
The
EMA grants access to the Priority Medicines, or PRIME, program to investigational medicines for which it determines there to be preliminary
data available showing the potential to address an unmet medical need and bring a major therapeutic advantage to patients. As part of
the program, the EMA provides early and enhanced dialogue and support to optimize the development of eligible medicines and speed up
their evaluation, aiming to bring promising treatments to patients sooner.
Periods
of authorization and renewals
A
marketing authorization is valid for five years in principle and the marketing authorization may be renewed after five years on the basis
of a re-evaluation of the risk-benefit balance by the EMA or by the competent authority of the authorizing member state. To this end,
the marketing authorization holder must provide the EMA or the competent authority with a consolidated version of the file in respect
of quality, safety and efficacy, including all variations introduced since the marketing authorization was granted, at least six months
before the marketing authorization ceases to be valid. Once renewed, the marketing authorization is valid for an unlimited period, unless
the European Commission or the competent authority decides on justified grounds relating to pharmacovigilance, to proceed with one additional
five-year renewal. Any authorization which is not followed by the actual placing of the drug on the E.U. market (in case of centralized
procedure) or on the market of the authorizing member state within three years after authorization ceases to be valid (the so-called
sunset clause).
Health
Care Reform
The
FDA’s and other regulatory authorities’ policies may change, and additional government regulations may be enacted that could
prevent, limit or delay regulatory approval of our product candidate. For example, Congress must reauthorize the FDA’s user fee
programs every five years and often makes changes to those programs in addition to policy or procedural changes that may be negotiated
between the FDA and industry stakeholders as part of this periodic reauthorization process. Congress most recently reauthorized the user
fee programs in September 2022 but without any substantive policy changes. If we are slow or unable to adapt to changes in existing requirements
or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval
that we otherwise may have obtained and we may not achieve or sustain profitability, which would adversely affect our business, prospects,
financial condition and results of operations.
As
previously mentioned, the primary trend in the U.S. health care industry and elsewhere is cost containment. Government authorities and
other third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medical
products and services, implementing reductions in Medicare and other health care funding and applying new payment methodologies. For
example, the ACA, among other things, increased the minimum Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate
Program; extended the Medicaid Drug Rebate Program to utilization of prescriptions of individuals enrolled in Medicaid managed care plans;
imposed mandatory discounts for certain Medicare Part D beneficiaries as a condition for manufacturers’ outpatient drugs coverage
under Medicare Part D; and established a Center for Medicare Innovation at the U.S. Centers for Medicare and Medicaid Services, or CMS,
to test innovative payment and service delivery models to lower Medicare and Medicaid spending.
We
expect that future changes or additions to the ACA, the Medicare and Medicaid programs and changes stemming from other healthcare reform
measures, especially with regard to healthcare access, financing or other legislation in individual states, could have a material adverse
effect on the health care industry in the United States.
In
addition, other legislative changes have been proposed and adopted in the United States since the ACA that affect health care expenditures.
These changes include aggregate reductions to Medicare payments to providers of up to 2% per fiscal year pursuant to the Budget Control
Act of 2011, which began in 2013 and was extended by the Consolidated Appropriations Act for 2023 and will remain in effect through 2032
unless additional Congressional action is taken.
21
Table of Contents
Moreover,
there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed 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 product pricing, review the relationship between pricing and manufacturer patient programs, and reform government
program reimbursement methodologies for drug products. Notably, on December 20, 2019, the Further Consolidated Appropriations Act for
2020 was signed into law (P.L. 116-94) that includes a piece of bipartisan legislation called the Creating and Restoring Equal Access
to Equivalent Samples Act of 2019 (the “CREATES Act”), which provides a legislatively defined private right of action under
which eligible product developers can bring suit against companies who refuse to sell sufficient quantities of their branded products
on commercially reasonable, market-based terms to support such eligible product developers’ marketing applications. The CREATES
Act aims to address the concern articulated by both the FDA and others in the industry that some brand manufacturers have improperly
restricted the distribution of their products, including by invoking the existence of a REMS for certain products, to deny generic and
biosimilar product developers access to samples of brand products. Because generic and biosimilar product developers need samples to
conduct certain comparative testing required by the FDA, some have attributed the inability to timely obtain samples as a cause of delay
in the entry of generic and biosimilar products. To remedy this concern, the CREATES Act establishes a private cause of action that permits
a generic or biosimilar product developer to sue the brand manufacturer to compel it to furnish the necessary samples on “commercially
reasonable, market-based terms.” Whether and how generic and biosimilar product developments will use this new pathway, as well
as the likely outcome of any legal challenges to provisions of the CREATES Act, remain highly uncertain and its potential effects on
our future commercial products are unknown. We cannot currently predict the specific outcome or impact on our business of such regulatory
and legislative initiatives.
In
August 2022, the Inflation Reduction Act of 2022, or the IRA, was signed into law, which is a measure from the Biden administration aimed
at reducing prescription drug costs and increasing access to innovative cell and gene therapies for Medicaid recipients. Among other
things, the IRA has multiple provisions that may impact the prices of drug products that are both sold into the Medicare program and
throughout the United States. Starting in 2023, a manufacturer of a drug or biological product covered by Medicare Parts B or D must
pay a rebate to the federal government if the drug product’s price increases faster than the rate of inflation. This calculation
is made on a drug product by drug product basis and the amount of the rebate owed to the federal government is directly dependent on
the volume of a drug product that is paid for by Medicare Parts B or D. Additionally, starting in payment year 2026, CMS will negotiate
drug prices annually for a select number of single source Part D drugs without generic or biosimilar competition. CMS will also negotiate
drug prices for a select number of Part B drugs starting for payment year 2028. If a drug product is selected by CMS for negotiation,
it is expected that the revenue generated from such drug will decrease. In addition to the IRA’s drug price negotiation provisions,
Executive Order 14087, issued in October 2022, called for the CMS innovation center to prepare and submit a report to the White House
on potential payment and delivery modes that would complement to IRA, lower drug costs, and promote access to innovative drugs. On his
first day in office, President Donald Trump repealed Executive Order 14087, which introduces uncertainty in federal drug pricing strategies.
At
the state level, individual states are increasingly aggressive in passing legislation and implementing 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. In December 2020, the U.S. Supreme Court held unanimously that federal law does not preempt the states’
ability to regulate pharmacy benefit managers (PBMs) and other members of the healthcare and pharmaceutical supply chain, an important
decision that appears to be leading to further and more aggressive efforts by states in this area. The Federal Trade Commission in mid-2022
also launched sweeping investigations into the practices of the PBM industry that could lead to additional federal and state legislative
or regulatory proposals targeting such entities’ operations, pharmacy networks, or financial arrangements. Significant efforts
to change the PBM industry as it currently exists in the United States may affect the entire pharmaceutical supply chain and the business
of other stakeholders, including biopharmaceutical developers like us. In addition, regional healthcare authorities and individual hospitals
are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription
drug and other healthcare programs. These measures could reduce the ultimate demand for our products, once approved, or put pressure
on our product pricing.
22
Table of Contents
We
expect that these and other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria
and in additional downward pressure on the price that we receive for any approved drug, which could have an adverse effect on customers
for our product candidate. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction
in payments from private payors.
There
have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal and state levels directed at
broadening the availability of healthcare and containing or lowering the cost of healthcare. The implementation of cost containment measures
or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our products.
Such reforms could have an adverse effect on anticipated revenue from plogo and any of our future product candidates that we may successfully
develop and for which we may obtain regulatory approval and may affect our overall financial condition and ability to develop product
candidates.
Competition
The
biotechnology and biopharmaceutical industries are rapidly changing and highly competitive. We are seeking to develop and market drug
candidates that will compete with other products and therapies that currently exist or are being developed. Other companies are actively
seeking to develop products that have disease targets similar to those we are pursuing. We face competition from many different sources,
including commercial, pharmaceutical and biotechnology companies, academic institutions, government agencies and private and public research
institutions. Many of our competitors have significantly greater financial, manufacturing, marketing and drug development resources than
we do. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements
with large and established companies. Our commercial opportunity will be reduced or eliminated if our competitors develop and commercialize
products that are safer, more effective, have fewer side effects or are less expensive than any products that we may develop. In addition,
competitors compete in the areas of recruiting and retaining qualified scientific and management personnel, establishing clinical trial
sites and patient registration for clinical trials, as well as in acquiring technologies and technology licenses. Some of these factors
can delay completion of recruitment into our clinical trials.
A
large number of drug candidates are in development for the treatment of leukemia and lymphomas, MDS, gastrointestinal, genitourinary,
gynecological and thoracic cancers and other advanced solid tumors. Cardiff Oncology has a PLK1 inhibitor in clinical trials and we believe
that Arbutus, Boehringer Ingelheim, GlaxoSmithKline, Merck, Onconova, and Takeda have been and may continue to be evaluating PLK inhibitors
for hemato-oncology indications. Several companies are pursuing discovery and research activities in each of the other areas that are
the subject of our research and drug development program.
Environmental
Social and Government (“ESG”) Matters
We
recognize the importance of ESG matters, with a specific focus on Human Capital Management, as integral to creating a sustainable foundation
for our long-term business strategy. We support professional development at all levels. We also take reports of suspected violations
of our codes of conduct and take seriously appropriate action.
As
we do not operate laboratories or manufacture products, we believe that our environmental impact is relatively small. We are involved
in office waste reduction practices.
Our
mostly remote workforce has further reduced our carbon footprint. We strive to offer excellent benefits and long-term incentives to help
retain our workforce.
Our
human capital resources and objectives include identifying, recruiting, retaining and incentivizing our existing and additional employees.
The principal purposes of our equity incentive plans are to attract, retain and reward personnel through the granting of equity-based
compensation awards in order to increase shareholder value and our success by motivating such individuals to perform to the best of their
abilities to achieve our objectives.
We
recognize that our industry is specialized and dynamic and a significant aspect of our success is our continued ability to execute our
human capital strategy of attracting, engaging, developing and retaining highly skilled talent. There is fierce competition both within
our industry and in the geographic locations in which we have offices for highly skilled talent, and we offer a robust set of benefits,
career-enhancing learning experiences and initiatives aligned with our mission, vision, and values in order to attract qualified prospective
employees and to retain and motivate our employees. We offer competitive compensation for our employees and strongly embrace a pay for
performance philosophy in setting and adjusting compensation.
