Overview
We are a clinical stage biopharmaceutical
company focused on developing therapies for the treatment of high impact, difficult to treat cancers through the inhibition of glycogen
synthase kinase-3 (GSK-3). We are developing elraglusib (formerly 9-ING-41), an ATP-competitive small molecule that is designed to enter
cancer cells and block the function of the enzyme glycogen synthase kinase-3 beta (“GSK-3β”), a master regulator of complex
biological signaling cascades, including those mediated by oncogenes, that lead to tumor cell survival, growth, migration, and invasion.
We believe that the blockade of GSK-3β signaling ultimately results in the death of the cancer cells and the regulation of anti-tumor
immunity.
We have exclusively licensed a
portfolio of GSK-3 inhibitors developed in a collaboration between The Board of Trustees of the University of Illinois-Chicago (“UIC”)
and Northwestern University (“NU”). Elraglusib is the lead drug in our portfolio and is being evaluated in a randomized Phase 2
trial in patients with metastatic pancreatic ductal adenocarcinoma (“mPDAC”), our most advanced clinical indication to date.
We are also advancing a Phase 1/2 clinical trial in refractory pediatric malignancies, including Ewing sarcoma (“EWS”).
Elraglusib represents a broad
opportunity for us to potentially initiate and advance multiple drug development programs around our lead asset based on data emerging
from completed or ongoing Phase 1/2 trials and non-clinical biological, cellular, and animal data. Animal tumor model data, Phase 1/2
clinical data and AI-based computational approaches have identified a number of areas of unmet clinical need in cancer treatment where
elraglusib may play an interventional role, including pancreatic, metastatic melanoma, lung, colon, breast, renal, and ovarian cancer,
leukemias and lymphomas, as well as some pediatric cancers including Ewing sarcoma, neuroblastoma and pediatric leukemias.
Elraglusib Injection
Our lead clinical program, referred
to as Actuate-1801, is an intravenous (“IV”) injection solution of elraglusib (“Elraglusib Injection”) that we
are evaluating for the treatment of first-line mPDAC.
To date, we have treated over
500 patients with Elraglusib Injection in Phase 1 and Phase 2 studies. Elraglusib Injection is currently being evaluated in a Phase 2
study (as part 3B of our Actuate 1801 protocol) as a weekly IV infusion in combination with gemcitabine/nab-paclitaxel (“GnP”).
Overall survival (“OS”) has been summarized throughout the study by following and reporting 1 year survival rate. The primary
endpoint at the end of the study will be summarized as median overall survival (“mOS”). The study completed enrollment in
January 2024, and top-line results are expected to be presented in the second quarter of 2025. As further described below, we conducted
a preliminary analysis of interim data in the pre-specified safety population as of November 15, 2024, at the point when >70% of death
events occurred in the GnP control arm. Log-rank analysis will be used to determine statistical significance when comparing the elraglusib/GnP
and GnP arms of the study.
1
The analysis of interim data demonstrated
that treatment with elraglusib in combination with GnP resulted in statistically significant increases in 1-year survival rate (p-value
of 0.002) and mOS (hazard ratio of 0.63, p-value of 0.016) versus treatment with GnP alone. The combination treatment also resulted in
increased Objective Response Rates (“ORR”) and Disease Control Rates (“DCR”) in the elraglusib/GnP combination
arm versus the GnP control arm. As depicted in Figure 1 and below, interim data highlights from the predefined safety population as of
the November 15, 2024 cutoff date include:
· The interim data met the primary endpoint with
a 1-year survival rate of 43.6% in the elraglusib/GnP combination arm versus 22.5% in the GnP control arm (p-value of 0.002).
· 18- and 24-month survival rates also demonstrated
benefit of 20.9% vs 0% and 16.7% vs 0% in the elraglusib/GnP combination vs GnP arms, respectively.
· In the elraglusib/GnP combination arm, 38% of
subjects were still alive vs 19% in the GnP control arm.
· A statistically significant 37% reduction in
risk of death and increased mOS were observed in the elraglusib/GnP combination arm (mOS of 9.3 months) vs the GnP control arm (mOS of
7.2 months), (hazard ratio of 0.63, p-value of 0.016).
· The trial also met its primary safety endpoint.
Treatment-emergent adverse events (“TEAEs”) and Serious Adverse Events (“SAEs”) in the elraglusib/GnP combination
arm were similar to those observed in the GnP arm, indicating a favorable risk-benefit profile for the elraglusib/GnP combination.
· The ORR was 27.7%, DCR was 42.6 %, and PFS was
5.6 months in the elraglusib/GnP combination arm versus 20.5%, 33.3% and 4.9 months in the GnP arm, respectively.
· Two patients in the elraglusib/GnP combination
arm with previously inoperable metastatic lesions with noted reductions in target lesions were referred for successful resection, one
of which resulted in 100% reduction in total tumor burden after surgery. In addition, there have been one Complete Response (“CR”)
and one Partial Response (“PR”) with 100% reduction in target lesions in the elraglusib/GnP combination arm versus none in
the control arm.
Figure 1: Actuate-1801 Part 3B:
Draft unaudited Phase 2 data of elraglusib in mPDAC (as of November 15, 2024).

As with all preliminary analyses
of interim data, this data should not be relied upon as a final analysis and is subject to change once full data analysis is complete.
At the completion of this Phase
2 study, we plan to meet with the U.S. Food and Drug Administration (the “FDA”) and discuss the design and execution of a
Phase 3 registration study. In addition, we plan to discuss the use of the Phase 2 data to support potential registration.
As discussed in more detail below
under “History of Elraglusib Clinical Development,” the Phase 2 trial followed the evaluation of Elraglusib Injection in a
Phase 1 dose escalation study (Actuate-1801 Part 1) in 238 adult patients with refractory advanced cancers when given as a single
agent (n=67) or in combination with chemotherapy (n=171). The objective of this study was to establish the safety profile of elraglusib
when used alone or in combination with chemotherapy and to identify either a maximum tolerated dose (“MTD”) or recommended
Phase 2 dose (“RP2D”) to then inform the design of exploratory efficacy studies in Phase 2. Subjects in this study were
diagnosed with a variety of cancer types and most patients had received two or more previous lines of chemotherapy prior to enrollment
in the study. Objective responses and durable disease control were observed in both the single agent and combination treatment arms of
the study. The most common TEAEs attributed to elraglusib were transient visual disturbance (patients described lights as brighter and
skin tones as darker, which resolved spontaneously) and fatigue across both study parts. The majority (>99%) of TEAEs that occurred
in ≥ 20% of patients were reported as Grade 1 or 2 (mild or moderate). In combination with chemotherapy, no new safety signals
were observed. While the elraglusib/GnP combination appears to be well-tolerated and well-managed in the clinic, we do not yet know whether
any increase in the number or severity of toxicities will be attributable to elraglusib and thus the elraglusib/GnP combination will have
its own safety profile that will need to be evaluated and discussed with regulators.
Based on the results of the Phase 1
study, we initiated a single arm Phase 2 study (“Actuate-1801 Part 3A” or “Part 3A”) in patients with
previously untreated mPDAC. This study was originally designed as a single arm exploratory Simon two-stage trial (and therefore not designed
or powered to demonstrate statistical significance). The elraglusib dose was started at the RP2D evaluated in the latter part of the Phase
1 trial (15 milligrams of drug per kilogram of body weight (mg/kg) administered twice weekly). No new safety signals were observed with
the elraglusib/GnP combination, but investigators observed that GnP toxicities may have occurred earlier and may have been more intense
in some patients than would be anticipated for GnP alone. For these reasons, the dose of elraglusib was proactively reduced near the end
of the Part 3A study to 9.3 mg/kg administered twice weekly. After an analysis conducted following the completion of Part 3A, which showed
an mOS of 15.3 months in the efficacy evaluable (n=29) patient population, we amended and expanded the second stage of the study
to a randomized, controlled trial now powered for statistical significance (“Actuate-1801 Part 3B” or “Part 3B”)
that would allow a comparison of the safety and efficacy of the combination of Elraglusib Injection plus GnP versus GnP alone in 286 patients.
In addition, Elraglusib Injection
is also being evaluated in pediatric cancer patients with recurrent/refractory solid cancers. This study, Actuate-1902, is a Phase 1/2
study that evaluated escalating doses of elraglusib as a single agent as well as in combination with irinotecan or cyclophosphamide/topotecan
in the Phase 1 portion. This study was based off the RP2D from the Actuate-1801 adult cancer study using twice weekly dosing of elraglusib.
Patients in this Actuate-1902 study also experienced a number of objective responses in the combination chemotherapy arms, and based on
this data, we identified Ewing sarcoma as a potential second indication for further development of Elraglusib Injection. Currently, the
Actuate-1902 study is open but only accruing patients with refractory Ewing sarcoma into the Phase 1 portion of the study. Subject
to future funding, we plan to further investigate the activity of elraglusib in the Ewing sarcoma patient population.
Elraglusib Oral Tablet Development Plans
We have developed several oral
dosage forms of elraglusib, which we believe will allow us to expand the number of cancer indications that we are able to target and allow
us to further explore more convenient dose delivery options for patients. A clinical candidate tablet, the Elraglusib Oral Tablet, has
been selected for further development and we are planning a Phase 1 study (Actuate-2401) to identify the MTD and RP2D for Elraglusib Oral
Tablet in adult patients with advanced, refractory cancers, subject to future funding. Subject to additional funding, several Phase 2
studies have been identified for further clinical development of Elraglusib Oral Tablet based on data from the Actuate-1801 study in indications,
including but not limited to, refractory, metastatic melanoma and refractory, metastatic colorectal cancer.

Our Market Opportunity
Treatment of Metastatic Pancreatic Ductal
Adenocarcinoma (“mPDAC”)
According to the American Cancer
Society, the annual incidence of pancreatic cancer is expected to exceed 67,000 patients in the United States in 2025 and approximately
70% of these patients will present with metastatic disease. A recent review of clinical trials in Future Oncology 1
showed that the mOS in patients with mPDAC treated with GnP ranged from approximately 3.6 to 9.8 months with an unweighted mOS of 6.9
months. Therefore, we believe the ability to extend survival by even a few months would be considered meaningful in this patient
population.
We are developing elraglusib
for patients with mPDAC who have not previously received systemic treatment for their metastatic disease. Due to lack of early symptoms,
approximately 80-90% of all patients with pancreatic cancer are unresectable, and present with advanced or metastatic disease. In addition,
80-90% of PDAC cases do not have a high tumor mutational burden in general, and are unlikely to respond to checkpoint inhibitors such
as pembrolizumab. Pembrolizumab has been approved for patients with metastatic solid cancer with high tumor burden but is rarely used
in metastatic pancreatic cancer for this reason. However, frequent mutations in KRAS and TP53 oncogenes drive pancreatic tumor growth
and treatment resistance, often making PDAC refractory to chemotherapy.
Current first-line therapies
for mPDAC consist of GnP, FOLFIRINOX, or irinotecan liposomal injection given with oxaliplatin, fluorouracil, and leucovorin (“NALIRIFOX”).
NALIRIFOX was recently approved (February 2024) and may provide an alternative to FOLFIRINOX with a somewhat improved safety profile.
The mOS in mPDAC patients
is 11.1 months with NALIRIFOX, 11.2 months with FOLFIRINOX and 7 to 10 months with GnP, respectively, in the first-line setting. NALIRIFOX
demonstrated superiority to GnP in the NAPOLI-3 trial (mOS 11.1 vs 9.2 months). However, safety profiles between these three chemotherapy
backbones are quite different: FOLFIRINOX leads to higher rates of neutropenia and nausea, NALIRIFOX has more gastrointestinal and constitutional
toxicity such as nausea, diarrhea and fatigue, and GnP treatment leads to increased myelosuppression and neurotoxicity. An analysis of
an insurance claims database indicated that first-line treatment from 2014-2018 was split between FOLFIRINOX and GnP. We believe it is
too early to predict how NALIRIFOX will fit into clinical use in patients with mPDAC.
Our management believes
elraglusib may improve outcomes in first-line mPDAC regardless of the chemotherapy backbone used. Patients with mPDAC are often resistant
or become resistant to the first-line chemotherapy backbones currently used to treat them. Part of elraglusib’s mechanism of action
is the ability to enhance chemotherapy activity even in resistant tumors and we believe this has been demonstrated in multiple animal
tumor models. In addition, elraglusib has shown the ability to enhance the activity of several chemotherapy drugs that comprise the current
first-line backbones in mPDAC including gemcitabine, nab-paclitaxel and irinotecan, suggesting the potential for elraglusib to be used
in combination with multiple first-line mPDAC treatments. In addition to the activity observed in our 1801 Part 3B study evaluating the
activity of elraglusib/GnP combination in mPDAC, an additional exploratory Phase 2 study is ongoing through an investigator initiated
trial (“IIT”) in patients with mPDAC evaluating the combination of elraglusib/FOLFIRINOX/losartan combination in up to 65
patients. Early evidence of increased clinical activity in patients receiving this combination was recently presented at the AACR Special
Conference on Advances in Pancreatic Cancer Research. This trial is being led by Dr. Colin Weekes at Massachusetts General Hospital (“MGH”)
and is supported by the Lustgarten Foundation as well as Actuate. Additional sites participating in the study include The University of
Colorado and the University of Washington’s Fred Hutchinson Cancer Center. Thus, our plan, subject to available funding, is to develop
elraglusib in combination with the present first-line chemotherapy regimens used in the treatment of mPDAC, as exemplified by our lead
program of elraglusib/GnP combination and later moving to combinations with either FOLFIRINOX or NALIRIFOX pending results of the FOLFIRINOX
combination trial. If shown to be clinically active, elraglusib/chemotherapy combinations could eventually be used to treat a large segment
of mPDAC patients.
Elraglusib has been granted Fast
Track and Orphan Drug Designations from the FDA for pancreatic cancer in the United States and Orphan Drug Designation for soft tissue
sarcomas in the United States. Elraglusib received Orphan Medicinal Product Designation (“OMPD”) for both pancreatic cancer
and sarcoma from the European Medicines Agency (“EMA”). Actuate is planning a Type D meeting with the FDA to discuss Phase
3 design and an End of Phase 2 (Type B) meeting to discuss future development plans in 2025.

Treatment of Ewing Sarcoma
An estimated 9,550 children (ages
0-14 years) and 5,140 adolescents (ages 15-19 years) are expected to be diagnosed with cancer in the United States in 2025. It was also
estimated that 1,050 children and 600 adolescents will die from the disease in the United States in 2025. While death rates for pediatric
and adolescent cancers have declined by more than 50% over the last five decades due to improved treatment options, there is still room
for improvement. Despite the improved survival offered by current therapies, approximately 40% of childhood cancer survivors have severe,
life-threatening or fatal complications within 30 years of diagnosis and up to 90% of survivors will have a chronic health condition by
the age of 45. These long-term effects are related to the type of treatment used such as chemotherapy and radiation which can have a material
adverse impact on developing organs. Work is ongoing to determine how to more effectively identify underlying mechanisms of pediatric
cancers in an effort to develop and administer more targeted, more effective and less toxic treatments.
Based on extensive preclinical
work in pediatric malignancies showing excellent synergy between elraglusib and standard of care chemotherapy in neuroblastoma, sarcoma,
glioma and others, we initiated the Actuate-1902 Phase 1 study to evaluate the safety of elraglusib +/- chemotherapy in pediatric patients
with refractory malignancies in 2020. The dose escalation part of the study assigned patients to elraglusib alone, elraglusib/irinotecan
or elraglusib/cyclophosphamide and topotecan (“CT”). As of December 31, 2024, 40 patients had been enrolled and received at
least one dose of elraglusib. No SAEs were observed with elraglusib monotherapy at the first two dose levels and positive results were
observed for some patients as discussed under “Our Solution – Current Elraglusib Development - Developing Elraglusib IV for
the Treatment of Ewing Sarcoma – Actuate 1902” below. Upon determination of RP2D for monotherapy and combination therapy,
we had originally intended to initiate a Phase 2 study in neuroblastoma. However, recently approved anti-GD2 antibodies have shown considerable
improvement of response rate, progression-free survival (“PFS”), and survival, making development in this population much
more challenging.
Based on the positive response
from a Ewing sarcoma patient further discussed below under “Developing Elraglusib Injection for the Treatment of Ewing Sarcoma –
Phase 1 and Phase 2 Plans – Actuate-1902,” six additional patients with metastatic, refractory Ewing and Ewing-like sarcoma
were enrolled in the elraglusib/CT combination arm. There are currently no known treatment regimens that meaningfully extend life in Ewing
sarcoma patients with metastatic, refractory disease. The five-year survival rate for patients who have recurrent (relapsed) disease is
<30%. Patients who are refractory and have metastases and disease progression despite two or more chemotherapy regimens generally have
a very short survival of 3-8 months. Twelve patients including ten Ewing sarcoma patients, one patient with desmoplastic small round cell
tumors (“DSRCT”) and one patient with CIC rearranged sarcoma were enrolled in our Actuate-1902 trial. All twelve patients
appear to have metastatic disease and had disease progression prior to joining the study despite undergoing previous treatment combinations
including chemotherapy, radiation, and/or surgical procedures. Eight patients received two or more previous chemotherapy regimens, prior
to entering the 1902 study. All patients received the combination of elraglusib and cyclophosphamide/topotecan. We believe this exploratory
Ewing sarcoma data, discussed further under “Developing Elraglusib IV for the Treatment of Ewing Sarcoma – Actuate 1902”
below, is sufficiently positive in this orphan pediatric cancer indication to consider additional development in Ewing sarcoma. The Actuate-1902
Phase 1 arm of the study is open to enrollment, focusing on recruitment of patients with refractory Ewing sarcoma.
The FDA has granted Rare
Pediatric Disease Designation (“RPDD”) to elraglusib for our treatment of EWS. Rare Pediatric Disease Designation is granted
by the FDA for serious or life-threatening diseases that affect fewer than 200,000 people in the United States and in which the serious
or life-threatening manifestations primarily affect individuals less than 18 years of age. If, in the future, a New Drug Application (“NDA”)
for elraglusib for the treatment of Ewing sarcoma is approved by the FDA, we may be eligible to receive a Priority Review Voucher (“PRV”)
that could be utilized by us or potentially sold to another company for its use.

Our Pipeline and Development Timeline
Our initial focus is on the development
of GSK-3 inhibitors for the treatment of cancers with ineffective treatment options and poor overall survival. Given our ability to formulate
elraglusib in both the Elraglusib Injection and Elraglusib Oral Tablet forms, if adequate funding is secured, and given the potential
to use it in different ways depending on the cancer type, we believe that elraglusib represents a pipeline in a molecule, as shown in
the Figure 2 below. We are currently focused on advancing our trials in mPDAC with Elraglusib Injection. Our ability to advance our ongoing
and planned clinical trials listed in Figure 2 will depend on whether we have or raise sufficient capital to support those trials.
Figure 2: Ongoing and planned clinical trials.
Our Strengths
We believe that we have several
strengths that support our vision of developing therapies for the treatment of high impact, difficult to treat cancers through the inhibition
of GSK-3, including:
· Advancing a potentially class-leading GSK-3β
inhibitor, elraglusib with a novel, multimodal mechanism of action (“MOA”), in multiple advanced trials for the treatment
of cancer.
· Broad potential with clinical responses (CRs/PRs) and disease control observed
across multiple cancer histologies.
· Extended survival and increased responses are observed in mPDAC and relapsed/refractory
Ewing sarcoma.
· Preliminary evidence of clinical benefit has also been observed in patients
with metastatic melanoma and relapsed/refractory colorectal and lung cancer.
· Oral version of elraglusib successfully evaluated in a Healthy Volunteer
Phase 1 study.
· Phase 1 dose escalation study planned in advanced
cancer patients.
· Broad composition of matter intellectual property protection and development
incentives.
· Orphan Drug Designations for pancreatic and other
cancer types; Fast Track Designation for pancreatic cancer.

Our Business Strategies
Subject to available financing,
we intend to develop elraglusib in a broad list of advanced cancer indications, initially in patients with refractory disease and with
an initial focus on metastatic pancreatic cancer. We believe that our two product candidates, Elraglusib Injection and Elraglusib Oral
Tablet, will provide us with two different dosage forms of drug product with different attributes that will allow us to tailor each dosage
form to a specific cancer type to potentially improve outcomes and compliance. Key elements of our strategy to accomplish this objective
include:
· Build a sustainable oncology company. Our
vision is to build a leading oncology company with a sustainable pipeline of target indications revolving around a patented, active product
candidate, elraglusib, that can be delivered in different ways to potentially treat a wide variety of cancers. To accomplish this, we
are focused on rapid advancement of our currently active clinical trials while curating and preparing additional indications for future
expansion of elraglusib development. This effort is led by Daniel Schmitt, our chief executive officer and founder, and Dr. Andrew
Mazar, our scientific co-founder and chief operating officer, who have more than 60 years of combined experience in the management
of biotechnology companies and healthcare investing. Mr. Schmitt has led and contributed to the successful development and launch
of multiple pharmaceutical and health technology products and executed over approximately $1.0 billion in milestone value through
licensing, acquisition, and development deals. Dr. Mazar has founded seven start-ups and is the co-founder, former chief scientific
officer and director, of Monopar Therapeutics, Inc. (Nasdaq: MNPR) as well as the former chief scientific officer of Attenuon, LLC. Dr. Mazar
has shepherded eleven drugs from discovery stage through Phase 2 and Phase 3 trials. Our board of directors (the “Board”)
is comprised of experienced entrepreneurs, scientists, business leaders and investors in the biotechnology industry .
· Advance our lead product candidate, elraglusib,
through clinical trials. We have generated clinical data from over 500 patients who have been dosed with elraglusib to date.
Under the innovative seamless study design of our Actuate-1801 Phase 1/2 clinical trial ( Figure 14: Actuate-1801 Master
Protocol Study Design ), we have initiated a Phase 2 trial testing Elraglusib Injection in combination with chemotherapy in mPDAC
under this Master Protocol (Actuate-1801 Part 3B). We are also advancing an opportunity in Ewing sarcoma as part of the Actuate-1902
Phase 1/2 study in pediatric refractory malignancies. Currently, the Phase 1 portion of the Actuate-1902 study is open but only
accruing patients with refractory Ewing sarcoma and we are working to amend the Phase 2 portion of this trial to focus on Ewing sarcoma,
which will require additional funding. We also intend to explore strategically identified IITs that may identify additional indications
and standard of care products to combine with elraglusib in indications that go beyond those already identified in Actuate 1801-Part 1
and 2, which allows us to further leverage our pipeline in a molecule. By collaborating with our network of oncology Key Opinion Leaders
(“KOLs”), we anticipate partnering to access non-dilutive funding for our IITs through both federal (e.g. NIH) and non-federal
(e.g. cancer-specific foundations, pharma partners) sources, to the extent available. For example, Actuate collaborated with Dr. Colin
Weekes to obtain Lustgarten Foundation grant support for the IIT currently being run at MGH. Actuate provides financial and resource support
for IITs in exchange for rights to the trial data but Actuate has no control over the design, conduct or timeline of an IIT.
· Advance our lead product candidate, elraglusib,
by obtaining regulatory development incentives to accelerate path to approval. One of our strategic objectives is to obtain
development incentives in the United States and in other countries that we believe may accelerate our path to drug approval: Orphan Drug
Designation (“ODD”), Fast Track Designation (“FTD”) and Breakthrough Therapy Designation (“BTD”) in
the United States; Orphan and priority medicines (“PRIME”) designations in the EU; and Orphan designations in Japan and Australia.
There is no guarantee that any such designation, if received, will lead to a faster development, regulatory review or approval process;
or increase the likelihood that a product candidate will receive FDA approval.
· Explore strategic partnerships that can
accelerate and maximize the potential of GSK-3 inhibitors. We will evaluate potential strategic (pharma) partnering opportunities
which could further help us to accelerate development of elraglusib by providing expertise, guidance, and funding to expand the pipeline
into different tumors and other disease areas that could benefit from GSK-3 inhibitor therapy, as discussed in more detail below. We may
also broaden the reach of our platform by selectively in-licensing technologies or novel product candidates. In addition, we will consider
potentially out-licensing certain geographic rights to elraglusib or other product candidates in our target indications or for indications
and industries that we are not currently pursuing ourselves.
7
· Leverage our academic and research partnerships. We
are actively engaging with regulators, KOLs, advocates and other stakeholders early and throughout the development process in each cancer
indication being considered for development to enhance the probability of technical success. We currently have clinical partnerships with
investigators conducting IITs with elraglusib at MGH and Dana-Farber Cancer Institute (“DFCI”). The trials are partially financially
supported by grants from us in amounts ranging from $500,000 to $700,000 depending on the study, to be paid on an enrollment milestone
basis, with the balance of study funds provided by the institutions or with grants from government or research institutions. We also provide
elraglusib for the study and input into study design. We retain the rights to any preexisting intellectual property and the right for
exclusively licensing any joint inventions resulting from the studies. The studies may be terminated by either party with 30 days’
notice (subject to appropriate offboarding and follow up care for enrolled patients). We expect to expand these pending additional funding
to explore indications beyond pancreatic cancer. We also have a research and development collaboration with Lantern Pharma to leverage
their artificial intelligence platform to further understand the effects of elraglusib and identify patient subtypes that are particularly
susceptible to GSK-3 inhibition. We expect to continue to leverage these partnerships and establish others to hone and expand our research
and development efforts.
About Elraglusib (9-ING-41)
There are no approved high-affinity
inhibitors of GSK-3β and we believe elraglusib is one of the most advanced GSK-3β inhibitors in clinical development. Elraglusib
was originally known as 9-ING-41 but was granted the elraglusib International Nonproprietary Names (“INN”) and United States
Adopted Names (“USAN”) generic name in 2021. The known major mechanisms of action of elraglusib are summarized in Figure 4
and emphasize the therapeutic potential of this drug in multiple cancer types. For these reasons, elraglusib represents a “pipeline
in a molecule” depending on the dosage form and how it is used in a particular cancer type. Our lead development program is seeking
to treat mPDAC in combination with GnP. Our clinical data to date and the development plan are also further discussed below.
Elraglusib may exert anticancer
activity through a variety of mechanisms that may be context and cancer type specific. For example, GSK-3β mediates signaling of
oncogenic PI-3K but if this oncogene is not expressed in a particular tumor, this would not be a pathway that could be targeted by elraglusib
in that tumor. Potential antitumor activity through GSK-3β inhibition may occur through the following six mechanisms of action (see
Figure 3 below):
(1) Immune modulation;
(2) Inhibiting cell proliferation;
(3) Reducing tumor fibrosis;
(4) Decreasing immune evasion;
(5) Increasing apoptosis and disrupting DNA damage repair; and
(6) Inhibition of epithelial-mesenchymal transitions (“EMT”).
Figure 3: Elraglusib mechanisms
of action.

(1) Immune modulation and inhibition of immune evasion
GSK-3β plays an important
role in immune cell function, as inhibition of GSK-3β can facilitate immune cell expansion, differentiation and activation including
T and natural killer (“NK”) cells. GSK-3β inhibition increases the ability of effector T cells to kill tumors in vivo
through the induction of effector proteins granzyme B and FasL in gastric cancer models. Additionally, inhibition of GSK-3β, with
both small molecules and small interfering RNA (“siRNA”), downregulates programmed cell death protein 1 (“PD-1”)
expression in CD8 and cytolytic T cells and enhances their function. GSK-3β inhibition also lowers PD-1 expression and promotes long-term
survival and generation of memory CAR-T cells in vivo. These memory T cells enabled 100% clearance of cancer cells after rechallenging
during tumor remission. Recently, inhibition of GSK-3β with small molecules was shown to reduce the expression of T cell immunoreceptor
with immunoglobulin and ITIM domain (“TIGIT”) and lymphocyte activation gene-3 (“LAG-3”), additional immune system
suppressing molecules that work in concert with PD-L1 (Programmed Death-Ligand 1) to reduce anti-tumor surveillance by the system. Combining
GSK-3β inhibition and LAG-3 blockade significantly enhanced clearance of melanoma tumors compared to either treatment alone. LAG-3
was recently validated as a cancer therapeutic target when the first anti-LAG-3 antibody, relatlimab, was approved in March 2022
by the FDA for treatment of patients with unresectable or metastatic melanoma.
Blocking GSK-3 in NK cells leads
to enrichment of mature NK cells and primes them for enhanced cytokine production and anti-tumor function in vivo. GSK-3β expression
was increased in the NK cells of patients with acute myeloid leukemia (“AML”) and inhibition of GSK-3β led to increased
cell directed cytotoxicity in these patient-derived samples. Inhibition of GSK-3 also decreased LAG-3 expression on NK cells.
GSK-3β activity has also
been tied to transforming growth factor β (“TGF-β”) expression. TGF-β released by cancer cells, stromal fibroblasts
and other cells in the tumor microenvironment further promotes cancer progression by shaping the architecture of the tumor and by suppressing
the anti-tumor activities of immune cells, thus generating an immunosuppressive environment that prevents or attenuates the efficacy of
anticancer immunotherapies. Therefore, blocking GSK-3β may reduce TGF-β-mediated immunosuppression.
Elraglusib has now been demonstrated
to decrease expression of PD-1, TIGIT and LAG-3 and to enhance the anti-tumor effects of anti-PD-1 checkpoint inhibition in animal tumor
models. Thus, elraglusib blockade of GSK-3β activity may improve immune response to tumors by augmenting the responsiveness of a
patient’s immune system in addition to the direct anti-tumor effects of elraglusib within the cancer cells themselves.
(2) Inhibiting cell proliferation
Inhibition of GSK-3β leads
to inhibition of tumor cell proliferation. This has been shown in multiple tumor model systems using elraglusib. A number of pathways
have been implicated in the inhibition of cell proliferation mediated by GSK-3 inhibitors including MYC, Cyclin D1, TGFα, epidermal
growth factor receptor, Ras, PI3K/Akt, and NF-κB. Given GSK-3’s role as an adapter of multiple signaling pathways, elraglusib
may exert its antiproliferative effects through the inhibition of one or more of these pathways.
(3) Reducing tumor fibrosis and (4) decreased immune evasion
A chronic inflammatory microenvironment
is conducive to tumorigenesis (e.g., pancreatitis patients are known to have increased risk of pancreatic cancer) and tumors can undergo
EMT, leading to increased metastasis, under inflammatory conditions. Moreover, several profibrotic cytokines (e.g., TGF-β, TNF-α
and IL-1) are secreted by inflammatory cells and tumor cells and converge to activate pathways that regulate EMT. Further, GSK-3β
has also been demonstrated to be a mediator of EMTs. Therefore, the inflammatory response designed to fight tumor progression also ends
up promoting metastasis and tumor-associated fibrosis. Tumor fibrosis presents multiple challenges to drug delivery and tumor immune recognition
and contributes to drug resistance by presenting physical barriers in the tumor microenvironment to drug and immune cell access. Elraglusib
has been shown to reduce the inflammation and signaling that contribute to immune system evasion in multiple animal models, including
lung and liver, suggesting another mechanism through which elraglusib may interfere in cancer growth.

(5) Increasing apoptosis and disrupting DNA damage repair
GSK-3 inhibits apoptosis pathways.
A number of studies have suggested that the primary mechanism of GSK-3-mediated apoptosis is through the NF-κB pathway. Apoptosis
is a mechanism of cell death that is often suppressed in cancer cells leading to cancer cell survival and resistance even after treatment
with chemotherapeutic drugs or radiation. Studies have shown that eliminating or inhibiting GSK-3β in cancer cells is able to restore
apoptosis to cells, leading to tumor cell death. These findings support GSK-3β as a potential therapeutic target to potentiate apoptosis
in cancer cells.
In addition to GSK-3β’s
role in regulating NF-κB activity, it has also been shown to modulate DNA damage repair (“DDR”) pathways. DDR pathways
are integral in both normal and cancer cells to maintain genomic integrity by sensing and responding to DNA damage. In normal cells, DDR
helps to identify and repair mutations or breaks in DNA and restore the normal, intact sequence. If the cell is unable to repair a DNA
lesion, these DDR pathways can then initiate cell death signaling to prevent neoplastic growth. In cancer, DNA repair has been subverted
to protect tumor cells from repairing DNA damage that would otherwise lead to spontaneous apoptosis. Cancers will often have mutations
in at least one DNA repair pathways leading to dysregulated cell growth and replication. Our collaborators have shown that elraglusib
inhibition of GSK-3β sensitizes pancreatic cancer cells to gemcitabine by disrupting TopBP1/ATR mediated cell-cycle arrest and DNA
repair. GSK-3β’s emerging role in regulating DDR pathways supports its use in combination with DNA damaging chemotherapy.
Inhibition of DDR pathways have
also been shown to enhance tumor immune recognition by immune checkpoint inhibitors such as anti-PD-1, creating neoantigens in tumors
that lead to recruitment of tumor infiltrating immune cells, decreased immune evasion and increased anti-tumor immune response. This provides
the link that couples the various elraglusib-related mechanisms of action through the targeting of GSK-3.
(6) Inhibition of epithelial-mesenchymal transition (EMT)
GSK-3β has been shown to
be a mediator of a number of signaling pathways that regulate the transition of tumor cells from an epithelial to mesenchymal phenotype
potentially contributing to tumor progression, a process known as EMT. Signaling through Wnt, Notch, TGF-β and Snail are known mediators
of EMT and their signaling is regulated through GSK-3β. Several toolkit GSK-3β inhibitors have been shown to inhibit EMT in
tumor models suggesting that this is a class effect and highlighting a similar mechanism for elraglusib.
Our Solution – Current Elraglusib Development
Elraglusib represents a broad
opportunity for us to potentially initiate and advance multiple drug development programs around our lead asset based on data emerging
from completed or ongoing Phase 1/2 trials. Our lead program is developing Elraglusib Injection for the first-line treatment of mPDAC.
mPDAC remains one of the highest unmet needs in oncology as the 5-year survival rate for PDAC (<10%) is one of the lowest of any cancer
type.
Developing Elraglusib Injection for the Treatment
of mPDAC – Phase 2 Studies
Actuate-1801 Part 3B
We are currently evaluating elraglusib
through the second part of a Phase 2 study, referred to as Actuate-1801 Part 3B, which was initiated under the Actuate-1801 Master
Protocol in patients with mPDAC who had not previously received systemic treatment for their metastatic disease.
This study was designed as a randomized,
controlled study with a run-in to explore two different dosing schedules of elraglusib/GnP (once weekly vs. twice weekly) in the hope
of potentially providing clinical support for moving to a more convenient, commercially viable elraglusib schedule. Pharmacokinetics were
also included in this study to address the potential for drug-drug interactions (“DDI”) between elraglusib and gemcitabine
or nab-paclitaxel. Management believes that confirmation of the Actuate-1801 Part 3A result discussed below in an adequately powered,
randomized study, would compare favorably with the recently approved irinotecan liposomal injection and would complement the other first-line
regimens currently used to treat mPDAC and provide a basis for approval for use in patients with mPDAC who had not previously received
systemic treatment for their metastatic disease.
10
Actuate-1801 Part 3B enrolled
its first patients in October 2021 and the run-in part of the trial demonstrated the weekly dosing of elraglusib was equivalent to
twice weekly dosing of elraglusib. All patients randomized to the elraglusib/GnP arm now receive weekly elraglusib in addition to GnP.
The trial accrued more readily than projected and enrollment was completed in January 2024. Below are the key inclusion criteria
and clinical endpoints in the study:
Inclusion Criteria:
· ≥ 18 years old with metastatic pancreatic
adenocarcinoma
· Participants must have measurable disease as
defined by RECIST1.1
· No prior therapy
· Total enrollment: 286
Endpoints:
· Primary endpoints: 1 year OS/mOS
· Secondary endpoints: ORR, DCR, PFS
· Sample size based on projected increase in 1-year survival from 35% in GnP
to 55% in elraglusib/GnP with α=0.05; 232 patients needed for 80% power
We conducted a preliminary analysis
of interim data in the pre-specified safety population as of November 15, 2024. As with all preliminary analyses of interim data, this
data should not be relied upon as a final analysis and is subject to change once full data analysis is complete. For this preliminary
analysis, we used data based on a cut-off date corresponding to the date when >70% of death events occurred in the GnP control arm.
The analysis of interim data demonstrated
treatment with elraglusib in combination with GnP resulted in statistically significant increases in 1-year survival rate (p-value of
0.002) and mOS (hazard ratio of 0.63, p-value of 0.016) versus treatment with GnP alone. The combination treatment also resulted in increased
ORR and DCR in the elraglusib/GnP combination arm versus the GnP control arm. Interim data highlights include the following:
· The interim data met the trial primary endpoint
with a 1-year survival rate of 43.6% in the elraglusib/GnP combination arm versus 22.5% in the GnP control arm (p-value of 0.002).
· 18-and 24-month survival rates also demonstrated
benefit of 20.9% vs 0% and 16.7% vs 0% in the elraglusib/GnP combination vs GnP arms, respectively.
· As of the November 15, 2024 cutoff, 38% of subjects
were still alive in the elraglusib/GnP combination arm vs 19% in the GnP control arm.
· A statistically significant 37% reduction in
risk of death and increased mOS were observed in the elraglusib/GnP combination arm (mOS 9.3 months) vs the GnP control arm (mOS 7.2 months),
(hazard ratio of 0.63, p-value of 0.016).
· The trial also met its primary safety endpoint.
TEAEs and SAEs in the elraglusib/GnP combination arm were similar to those observed in the GnP arm, indicating a favorable risk-benefit
profile for the elraglusib/GnP combination. (See Figure 11 for a summary of TEAEs of any grade reported in >20% of patients treated
with elraglusib).
· At the interim cutoff of November 15, 2024, the
ORR was 27.7%, DCR was 42.6 %, and PFS was 5.6 months in the elraglusib/GnP combination arm versus 20.5%, 33.3% and 4.9 months in the
GnP arm, respectively.
· As of November 15, 2024, two patients in the
elraglusib/GnP combination arm with previously inoperable metastatic lesions with noted reductions in target lesions were referred for
successful resection, one of which resulted in 100% reduction in total tumor burden after surgery. In addition, there have been one CR
and one PR with 100% reduction in target lesions in the elraglusib GnP combination arm versus none in the control arm to date.

This is an open-label study and
therefore, the study could not be used to support accelerated approval which would be based on evaluation of surrogate endpoints.
Management expects top-line data
will be presented in the second quarter of 2025 based on the completion of enrollment in January 2024.
At the conclusion of Phase 2 trial
(Actuate-1801 Part 3B), we expect to have survival data on the elraglusib/GnP combination arm and GnP arm in patients with mPDAC
who had not previously received systemic treatment for their metastatic disease. At the completion of this study, we plan to meet with
the FDA and discuss the design and execution of a Phase 3 registration study, if justified by the results this study. In addition,
we plan to discuss the use of the Actuate-1801 Part 3B data for regulatory support and to support possible registration if the study
achieves its primary endpoint of showing improved survival over GnP alone. Moreover, while the elraglusib/GnP combination appears to be
well-tolerated and well-managed in the clinic, we do not yet know whether any increase in the number or severity of toxicities will be
attributable to elraglusib and thus the elraglusib/GnP combination will have its own safety profile that will need to be evaluated and
discussed with regulators. Figure 11 is a summary of the safety events reported as of November 15, 2024.
15
Actuate-1801 Part 3A
Actuate-1801 Part 3A is a single
arm Phase 2 trial that was initiated in patients with mPDAC who had not previously been treated with any systemic chemotherapy including
GnP (first-line study) and which built on the results of Actuate-1801 Part 2 described below, allowing a comparison of the safety
and efficacy of the combination of Elraglusib Injection plus GnP as compared to GnP alone. By moving our development into the first line
setting, we increased our ability to deliver the elraglusib/GnP combination to many more patients since more than 70% of patients with
mPDAC never go on to a second-line treatment once they have progression on first-line treatment. In addition, we believe that the safety
profile of elraglusib/GnP provides a strong basis for testing this combination in first-line patients. We also received a number of commercialization
incentives (e.g. ODD, FTD) through registration for pancreatic cancer including mPDAC. Results from the Actuate-1801 Part 3A study formed
the basis for the initiation of Actuate-1801 Part 3B trial.
In Part 3A of the Phase 2
study under the Actuate-1801 Master Protocol, the efficacy evaluable (“EE”) patient population was pre-defined as the efficacy
analysis population and the modified intent to treat (“mITT”) was the safety population. The elraglusib dose was started at
the RP2D evaluated in Part 2 (15 mg/kg dosed twice weekly).
The original study design proposed
to enroll 23 consecutively evaluable patients who met the definition for the EE. These patients could be replaced at the discretion of
the independent data monitoring committee (“IDMC”). Consequently, six patients were replaced such that there were 29 EE patients
in the study. No new safety signals were observed with the elraglusib/GnP combination, but investigators observed that GnP toxicities
may have occurred earlier and may have been more intense in some patients than would be anticipated for GnP alone. For these reasons,
the dose of elraglusib was proactively reduced near the end of the study to 9.3 mg/kg dosed twice weekly, with the final four patients
enrolled being treated at this dose.
Figure 10 below is a summary of
the response of patients with mPDAC treated with the elraglusib/GnP combination in Part 3A (data cutoff as of March 2023) in the
29 EE patients.

The mOS for the EE and ITT were
15.3 months and 11.9 months, respectively. These compare favorably with the mOS for GnP alone of 8.5 months in the MPACT
trial or more recently 9.2 months in NAPOLI-3 trial, which evaluated irinotecan liposomal injection (Onivyde®) in combination
compared to GnP, in the first-line mPDAC setting.

Elraglusib Injection was initially
evaluated in Actuate-1801 Part 1/2, a dose escalation study in adult patients with refractory advanced cancers when given as a single
agent or in combination with chemotherapy. The objective of this study was to establish the safety profile of elraglusib when used alone
or in combination with chemotherapy and to identify either an MTD or RP2D to then inform the design of exploratory efficacy studies in
Phase 2. Figure 14, which shows the study design process, and additional information regarding Actuate 1801 Master Protocol and potential
future development opportunities (for which funding would need to be raised) identified through Actuate 1801 Parts 1 and 2 are set forth
under “History of Elraglusib Clinical Development” below.
Overview of Interim Safety Profile from Phase 2 Trial (Actuate-1801
Part 3B)
Figure 11 provides safety
data as of November 15, 2024 from the Actuate-1801 Part 3B trial. TEAEs broadly encompass all adverse events observed while a patient
is on study and could be due to the drug or drugs (if used in combination), the disease or something specific to a particular patient
such as other diseases or illness. It is then up to individual clinical investigator to decide which toxicities are due to elraglusib.
The most common TEAEs attributed to elraglusib were transient visual disturbance and fatigue across both study parts, and the majority
of TEAEs that occurred in ≥ 20% of patients were reported as Grade 1 or 2 (Figure 11). Visual disturbance affected 66.5% of patients
(n=103/155) receiving elraglusib plus GnP and 9.0% of patients (n=7/78) receiving GnP alone. Commonly reported symptoms were darkened
vision, where patients described lights as brighter and skin tones darker. Greater than 99% of visual disturbance cases were reported
as mild or moderate (Grade 1 or 2). These visual disturbances were considered dose-dependent, occurring more frequently and lasting longer
at higher doses. All cases of visual disturbance were transient, resolved completely, and lacked any associated retinal, ocular, or systemic
toxicity. Fatigue, while also observed in ≥ 20% of patients, was also reported as mild or moderate (Grade 1 or 2) and did not interfere
with daily life.
Some of the key findings from the interim safety analysis
as of November 15, 2024 include:
· Overall rates of TEAEs and/or SAEs observed were
similar in the elraglusib + GnP-treated patients as compared to GnP-treated patients.
· Treatment discontinuation due to TEAEs were similar
across the treatment groups.
· Visual impairment and fatigue were major TEAEs
attributed to elraglusib as a single agent in 1801 Part 1 and were mild to moderate. 1
o Transient visual impairment described as transient alterations in color and skin tones under fluorescent
light.
o No permanent changes to eye structure or vision.

Investigator-Initiated Trial – PDAC
Elraglusib is also currently being
evaluated in an IIT focusing on adults with untreated metastatic pancreatic adenocarcinoma. IND 157435, a Phase 2 study of FOLFIRINOX
combined with elraglusib and the TGF-β inhibitor losartan in patients with untreated metastatic adenocarcinoma is being conducted
by Dr. Colin Weekes (the “Weekes IIT”). This study administers elraglusib by intravenous infusion twice weekly in combination
with FOLFIRINOX administered once every 14 days and daily losartan in adults with pancreatic cancer who have not received any prior
systemic therapy for advanced disease. As of December 31, 2024, 57 patients have been enrolled in the Weekes IIT and the study is ongoing.
We will receive all final data
from this study, which is considered exploratory and may inform future development of elraglusib. For additional information regarding
other IITs involving elraglusib, see additional information below.

Developing Elraglusib Injection for the Treatment of Ewing Sarcoma
– Phase 1 and Phase 2 Plans – Actuate-1902
As discussed under “Our
Market Opportunity” above, based on extensive preclinical work in pediatric malignancies showing excellent synergy between elraglusib
and standard of care chemotherapy in neuroblastoma, sarcoma, glioma and others, we initiated the Actuate-1902 Phase 1 study to determine
the safety of elraglusib +/- chemotherapy in pediatric patients with refractory malignancies in 2020. Based on the response from the Ewing
sarcoma patient, additional patients with metastatic, refractory Ewing and Ewing-like sarcoma were enrolled in the elraglusib/CT arm of
the 1902 Phase 1 study.
Twelve patients including ten
Ewing sarcoma patients, one DSRCT patient and one CIC rearranged sarcoma patient have been treated in the Actuate-1902 Phase 1 trial with
a combination of elraglusib and cyclophosphamide/topotecan. All twelve patients appeared to have metastatic disease and had disease progression
prior to joining the study despite undergoing previous treatment combinations including chemotherapy, radiation, and/or surgical procedures.
Eight patients received two or more previous chemotherapy regimens, prior to entering the 1902 study. The following represents the status
of Actuate-1902 Phase 1 trial as of December 31, 2024:
· One Ewing sarcoma patient with the CR stopped
all treatments after Cycle 5 and patient was reported alive as of December 31, 2024 (OS of 1,138 days).
· A second Ewing sarcoma patient had a PR of their
target lesion and a Complete Metabolic Response (“CMR”) of two secondary lesions by FDG-PET. This patient received treatment
for 10.5 cycles before transitioning to monotherapy in August 2024. This patient continues on monotherapy with no change in tumor status
or response as of February 4, 2025.
· A third patient had a partial response with a
52% reduction in tumor burden compared to baseline and the patient ended treatment after 3 cycles with OS of 368 days.
· Three Ewing sarcoma patients had best overall
response as stable disease, two patients were removed from treatment prior to week two and four patients were reported as having progressive
disease.
· As of December 31, 2024, three of twelve patients
remain alive and one patient continues on monotherapy treatment with elraglusib.
We believe that this exploratory
Ewing sarcoma data is sufficiently positive in this orphan pediatric cancer indication to consider additional development and treatment
options in Ewing sarcoma. The Actuate-1902 Phase 1 arm of the study is open to accrual.
With future funding, and pending
1902 data review at the end of Phase 1, we plan to evaluate additional treatment options focusing on patients with Ewing sarcoma.
Given that Ewing sarcoma is a
very rare pediatric cancer, an international consortium of investigators and sites will be needed to advance this program to registration.
In addition, we plan to pursue a number of development incentives in the United States and parallel programs in the EU. In July 2024,
we received ODD from the FDA for elraglusib for the treatment of soft tissue sarcomas in the United States and Orphan Medical Product
Designation from the EMA for the treatment of sarcoma. In October 2024, we received RPDD from the FDA for the treatment of Ewings sarcoma.
The ability to engage in further development in pediatric cancers will depend on our ability to raise sufficient additional capital to
support this path. We believe that pursuing this development could be an efficient and rapid path to registration in the United States
and Marketing Authorization in the EU.
Elraglusib Oral Tablet Development - Actuate-2203 and Actuate-2401
We have been developing several
oral dosage forms of elraglusib in addition to Elraglusib Injection that will potentially allow for further dose exploration and potentially
allow us to evaluate elraglusib as a single agent and in combination with additional chemotherapy backbones. We believe that we will be
able to administer the Elraglusib Oral Tablet daily, which may allow the drug to achieve steady state levels in plasma in patients resulting
in continuous inhibition of the target GSK-3 in tumor and tumor-associated cells.
19
Preclinical studies have shown
that persistent exposure of tumor cells (>12 hours but longer exposures work better) is required to observe induction of apoptosis
in these tumor cell line models. Both the liquid and solid oral dosage forms of elraglusib are highly bioavailable. However, we have chosen
to advance the Elraglusib Oral Tablet into clinical development based on an assessment of potential compliance, convenience of use and
taste that favor the Oral Tablet. Investigational product has already been manufactured under Good Manufacturing Practice (“GMP”)
standards, and we are planning a First in Human (“FIH”) Phase 1 clinical trial (Actuate-2401). Subject to additional
funding, we plan to initiate a dose escalation Phase 1 trial in patients with advanced solid cancer to identify the MTD/RP2D for
the Elraglusib Oral Tablet. Our development plan would then be to pursue Phase 2 indications such as metastatic melanoma, metastatic
colorectal cancer and/or non-small cell lung cancer (“NSCLC”) using the oral tablet. We would require additional funds to
initiate and complete these Phase 2 studies.
An oral liquid was evaluated for
bioavailability in a Phase 1 healthy volunteer study (Actuate-2203) at a single dose using a cross-over design such that each subject
on the study received IV, oral liquid after fasting and oral liquid with food. Elraglusib oral liquid was approximately 50% bioavailable
when given with food and was very well tolerated by healthy volunteers, as depicted in Figure 12.
Figure 12: Bioavailability of Elraglusib Oral
Liquid in Phase 1 Human Healthy Volunteer Study.
The oral liquid and several oral
tablets formulations were also evaluated for bioavailability in dogs and an oral tablet candidate was identified that was greater than
95% orally bioavailable when given with food. For the first time, an MTD was identified with any formulation or dosing schedule of elraglusib.
In the past, elraglusib had been given up to 3 times a week in animal toxicology studies to cover twice weekly and once weekly dosing
of Elraglusib Injection in the Actuate-1801 and Actuate-1902 studies, but never daily. In the study, the oral drug had an AUC24 (Area
Under the serum Concentration vs. time curve for 0-24 hours) of 77,000 ng•h/mL (nanograms times hours per milliliter) after a single
250 mg oral tablet and 137,000 ng•h/mL after oral administration of 500 mg (2 x 250 mg tablets) as shown in Figure 13. The 500 mg
dose demonstrated toxicity and was not tolerated by dogs but the 250 mg dose was well-tolerated when given daily for 28 days in this
exploratory study. This simulated the expected daily dosing that we would plan to use in our FIH Phase 1 study. The 25 mg/kg daily
dose in dogs corresponds to approximately the 9.3 mg/kg weekly dose currently being used in the Actuate-1801 Part 3B study when scaled
from dog to humans. Our management expects that steady state exposures of 77,000 ng•h/mL or greater will be possible with the Elraglusib
Oral Tablet at well-tolerated doses in humans. Based on these observations, we would expect to also reach MTD in the Elraglusib Oral Tablet
Phase 1 study in patients with refractory advanced cancer.
We believe this will allow for
additional opportunities to explore the anti-tumor activity of elraglusib with the oral tablet that could not be achieved with Elraglusib
Injection. While the weekly dosing of the Elraglusib Injection pairs well with GnP since both are given once per week, the oral tablet
may be more amenable to use with other, less convenient chemotherapies, as well as a single agent.

History of Elraglusib Clinical Development
Figure 14 is a graphical depiction
of the Actuate-1801 Master Protocol and study design process, followed by a discussion of the history of elraglusib clinical development
that led to finding that elraglusib plus GnP was well-tolerated in pre-treated cancer patients and selecting previously untreated mPDAC
as our lead indication.

Master Protocol Study Design
21
Actuate-1801 Phase 1/2 Clinical Study
We developed an innovative Phase 1/2
adaptive design “basket” clinical study to efficiently evaluate elraglusib safety and initial anti-tumor activity across multiple
tumor types. This trial design facilitated the rapid advancement of elraglusib through dose escalation and safety cohorts while later
establishing a process for transition into Phase 2 efficacy studies in patient populations that showed evidence of anti-tumor activity
during the safety portion of the study. Elraglusib has been dosed in over 500 patients to date both as a single agent and in combination.
The study design consists of three
parts. Part 1 and Part 2 consist of the evaluation of the safety and tolerability of elraglusib to determine the MTD and RP2D
as both a monotherapy and in combination with various chemotherapy regimens. Part 1 and 2 involve dose escalation of elraglusib to
identify either the MTD or RP2D if an MTD cannot be achieved. These were run in tandem and interdigitated. Initial dose escalation was
performed using single agent elraglusib (Part 1), but once Part 1 opened the fourth dose level, Part 2 was allowed to open
at the third dose level in combination with the chemotherapy backbones evaluated. Dose escalation was then continued for Part 1 and
2 in tandem until MTD or RP2D were identified, with Part 2 always being one dose level behind Part 1. A key design element of
Part 2 is that all subjects enrolled in a chemotherapy basket must have previously failed that chemotherapy such that each patient
was re-challenged by a drug to which they are resistant. Thus, each patient acts as their own control since any disease control must be
due to the combination. In Part 2, six dose levels of elraglusib were evaluated across eight different chemotherapy baskets. Part 3
is designed to assess the clinical benefit of elraglusib at the RP2D from Part 2 in combination with chemotherapy in specific cancer
populations.
Between January 2019 and
August 2021, patients participating in the Actuate-1801 Part 1 and Part 2 study received at least one dose of elraglusib as monotherapy
(n=67; Part 1) or in combination with chemotherapy (n=171; Part 2). Twenty-one different cancer types were enrolled in Part 1.
On average, patients had received and failed at least three previous lines of chemotherapy regimens. No dose-limiting toxicities (“DLTs”)
related to elraglusib occurred in either Part 1 or Part 2. Since the MTD was not reached in either part of the study, 15 mg/kg,
the pre-specified highest dose evaluated in both Actuate-1801 Part 1 and 2, was named the RP2D. The chemotherapy backbone and cancer
types involved in the study included:

Parts 1 and 2 comprised the Phase 1
portion of the Actuate-1801 trial and the results of this study were recently published in Clinical Cancer Research (Carneiro
et. al 2024).
22
Despite the fact that the patients
enrolled on the Actuate-1801 study had previously received and failed multiple chemotherapy regimens, the mOS was 7.7 months (95%
CI, 5.1-9.7) for elraglusib monotherapy (Part 1) and 6.9 months (95% CI, 5.7-8.9) for the combination of elraglusib and chemotherapy
(Part 2) across all the different chemotherapy baskets. The mOS of 7.7 months in Part 1 benchmarks favorably with mOS 8-10 months
for other active single agents evaluated in Phase 1. CR, PR and stable disease (“SD”) were determined using RECIST 1.1.
Only evaluable patients as defined per the Actuate-1801 Master Protocol experiencing stable disease ≥4 cycles of treatment are counted
as “stable.” Our management believes that 51.6% of patients in Actuate-1801 Part 1 and 49.3% in Actuate-1801 Part 2
with a response or stable disease who are able to stay on for at least four cycles of treatment is encouraging given the advanced and
treatment-refractory nature of their cancers.

Figure 15: Best overall response of elraglusib
as monotherapy (Part 1) and in combination with chemotherapy (Part 2)
To further demonstrate that elraglusib
shows single agent anti-tumor activity, an analysis was conducted regarding tumor size reduction and tumor tissue for the expression (presence)
of GSK-3β (as the target for elraglusib) using a validated immunohistochemical method.
Of the patients evaluated for
a tumor size reduction response, 15 out of 51 demonstrated tumor size reduction even if they did not reach a level of reduction associated
with a RECIST response. Our management believes that the reason for this response is the administration of elraglusib since it is the
only anticancer drug given in this part of the trial. Of the enrolled patients in Part 1, 16 patients had rapid clinical deterioration
related to their disease. These patients were unable to stay on treatment long enough to reach their first tumor assessment and are therefore
not included in the Part 1 analyses as per the protocol. Several tumor types are represented with clinical data in Part 1 including
melanoma, colorectal, appendix, and lung, providing initial rationale for future studies in these cancer types.
Tumor tissues from both Actuate-1801
Part 1 and Part 2 were analyzed for the expression (presence) of GSK-3β using a validated immunohistochemical method. Archival
and fresh pre-dose samples of tumor tissue were analyzed with 59.4% of tumor samples in Part 1 and >80% of samples in Part 2
immunostaining positive for GSK-3β, demonstrating that the target for elraglusib is present in a large portion of tumors across all
the cancer types enrolled in this study. Our management believes that this broad expression of GSK-3β supports the development of
elraglusib in several different cancer types.
As the Actuate-1801 study was
ongoing, studies in preclinical tumor models from several collaborating laboratories that were evaluating elraglusib reported that elraglusib
was also able to regulate expression of immune checkpoints such as PD-1/PD-L1, LAG-3 and TIGIT. The data further credentialed GSK-3β
as a novel target for mediating anti-tumor immunity, which had been reported by a number of groups over the past decade, and demonstrated
the potential for immune checkpoint modulatory activity for elraglusib. These were novel observations for elraglusib in addition to previously
described roles in attenuating anti-apoptotic activity, NF-κB and DDR mediated drug resistance and enhancing chemotherapy and suggested
that elraglusib may inhibit tumor progression through multiple mechanisms of action.
23
Circulating tumor cells isolated
from a patient with adult T cell leukemia/lymphoma (“ATLL”) in the Actuate-1801 study (Part 1) who experienced a durable
PR (406 days) while on single agent elraglusib also exhibited robust cytokine changes when treated with elraglusib ex vivo. Further,
Huntington et al 2 showed that plasma from elraglusib-treated patients in the Actuate-1801 Part 1 clinical study
demonstrated reduced VEGF and BAFF and elevated IL-1β, CCL22, and CCL4 concentrations that correlated with longer survival. Using
paired tumor biopsies from patients in the Actuate-1801 study, Huntington et al also showed that tumor-infiltrating immune cells
had reduced expression of inhibitory immune checkpoints (VISTA, PD-1, PD-L2) and elevated expression of T cell activation markers (CTLA-4,
OX40L) after elraglusib treatment.
Taken together, our management
believes that these early studies further support elraglusib’s multimodal mechanism of action including immune modulation and inhibition
of immune evasion. Given that a number of recent reports have highlighted that drugs that modulate anti-tumor immune response may improve
mOS with little or no effect on ORR, we re-analyzed all the Actuate-1801 Part 1 and 2 data with respect to OS.
Support for planned Phase 2
indications is provided by data extracted from Actuate-1801 Part 1 in patients with metastatic melanoma. Actuate-1801 Part 1
enrolled 11 patients with metastatic melanoma who received only single agent elraglusib and demonstrated an mOS of 9.1 months, which
compares favorably to the mOS of 6.9 months for salvage chemotherapy in a similar patient population. Our management believes that
we have potentially identified a method for enriching patients diagnosed with metastatic melanoma who are refractory to checkpoint inhibitors
but may benefit from elraglusib. Patient selection and enrichment could improve the probability of success in a future Phase 2 trial
in melanoma. These 11 Actuate-1801 Part 1 patients were refractory to several lines of treatment including immune checkpoint inhibitors
and would typically be candidates for chemotherapy salvage with an expected mOS of 6.9 months based on a meta-analysis of many different
chemotherapy regimens tested in the salvage setting in this patient population. In Actuate-1801 Part 1, one metastatic melanoma patient
with widely metastatic disease to the brain, lungs, bones, muscles, stomach, lymph nodes, pancreas and adrenal glands received Elraglusib
Injection as a single agent. This patient was refractory to all FDA-approved standard therapies, including several checkpoint inhibitors
and a BRAF/MEK inhibitor. This patient reported a partial response at 6 weeks and after 12 weeks on elraglusib, the patient’s brain
MRI showed a CR by RANO criteria and a PET scan showed CMR for other lesions. This patient continues to have a durable CMR ongoing (>5.5 years
as of November 15, 2024) and continues to receive the investigational drug elraglusib. A second melanoma patient who received single agent
elraglusib has ongoing stable disease and was still alive for 3.1 years as of last documented alive date. This patient also failed
all FDA-approved standard therapies including immune checkpoint inhibitors and several experimental treatments. These are extraordinary
results and should not be considered representative of all patients or all outcomes.
Similarly, Actuate-1801 Part 2
data in the irinotecan chemotherapy basket identified metastatic colorectal (in combination with irinotecan) as another potential Phase 2
indication for elraglusib based on mOS of 6.9 months for patients who were heavily pre-treated and refractory to chemotherapy. This
compares favorably with expected mOS of less than 3 months for this same patient population treated with salvage chemotherapy or
best supportive care.
Safety in Actuate-1801 Part 1 and 2
In both Parts 1 and 2, all patients
experienced TEAEs. TEAEs broadly encompass all adverse events observed while a patient is on study and could be due to the drug or drugs
(if used in combination), the disease or something specific to a particular patient such as other diseases or illness. It is then up to
the individual clinical investigator to decide which toxicities are due to elraglusib. The most common TEAEs attributed to elraglusib
were transient visual disturbance and fatigue across both study parts, and the majority of TEAEs that occurred in ≥ 20% of patients
were reported as Grade 1 or 2. Visual disturbance affected 50.7% of patients (n=34/67) receiving elraglusib monotherapy and 60.8% of patients
(n=104/171) receiving elraglusib with chemotherapy. Commonly reported symptoms were darkened vision, where patients described lights as
brighter and skin tones appearing darker. Greater than 99% of visual disturbance cases were reported as mild or moderate (Grade 1 or 2).
These visual disturbances were considered dose-dependent, occurring more frequently and lasting longer at higher doses. All cases of visual
disturbance were transient, resolved completely, and lacked any associated retinal, ocular, or systemic toxicity. Fatigue, while also
observed in ≥ 20% of patients, was also reported as mild or moderate (Grade 1 or 2) and did not interfere with daily life.

Other IIT
In addition to the company sponsored
trials and the Weekes IIT referenced above, elraglusib is currently being evaluated in an additional IIT. We track patient accrual and
SAEs in these trials and report these to our IND.
IND 156280 is a Phase 2 study
of elraglusib plus carboplatin in patients with advanced, metastatic salivary gland carcinoma being conducted by Dr. Glenn J. Hanna. This
study administered elraglusib by intravenous infusion twice weekly in combination with carboplatin administered once every 21 days
in adults with incurable, recurrent or metastatic salivary gland carcinomas. A total of 32 patients were enrolled and this study is now
completed. Final data analysis is ongoing and the study has been submitted for presentation at the AACR Annual Meeting 2025 with a final
data report anticipated by the end of 2025. The elraglusib dose used in this study is lower than the levels recommended by our studies.
License Agreements
Northwestern University License Agreement
We licensed the exclusive worldwide
rights to materials and non-exclusive rights to certain know-how relating to the use for therapeutic, diagnostic and commercial research
purposes of elraglusib and related compounds in cancer and combination therapies from NU pursuant to that certain royalty-free license
agreement between us and NU dated March 31, 2015, as amended on April 29, 2019 (as amended, the “NU License Agreement”).
Pursuant to the NU License Agreement,
NU granted us (i) a nonexclusive license to certain technical information developed in the laboratory of Dr. Mazar, and (ii) an
exclusive license to all results obtained by Dr. Mazar and his collaborators at NU on the use of the GSK-3β inhibitor 9-ING-41
and related compounds used for the treatment of cancer and combination therapies. The term of the NU License Agreement continues in effect
until the expiration of the last to expire of patent rights covering 9-ING-41 and related GSK-3 inhibitors (see the discussion under “ Intellectual
Property” below for a discussion of our expected patent terms), unless earlier terminated by NU due to our making a general
assignment for the benefit of creditors, initiation of bankruptcy proceedings by or against us or the appointment of a receiver or trustee
to take possession of our property, or by either party following 90 days’ notice of a material breach of the NU License Agreement
that is not then cured. The NU License Agreement terms are subject to the provisions of the Bayh-Dole Act, including requiring us to substantially
manufacture products related to the license in the United States, unless waived. While the drug substance (“DS”) for elraglusib
is manufactured by a supplier in China, the end drug product is substantially manufactured in the United States.
In consideration of the license
granted by NU, we issued 27,778 shares of our common stock to NU, which represented 5% of our then-outstanding fully-diluted shares and
agreed to customary confidentiality and progress update obligations and to indemnify NU for any claims arising from our use of the licensed
rights under the NU License Agreement.
UIC Exclusive License Agreement with Equity
The exclusive rights to Patent
Rights (as defined in the UIC License Agreement and described further below) and Technical Information (as defined in the UIC License
Agreement) surrounding GSK-3 inhibitors for Neurodegenerative Disorders were licensed through an Exclusive License Agreement with Equity
between us and UIC, dated April 6, 2015, as amended on April 24, 2019 (as amended, the “UIC License Agreement”).
Under the UIC License Agreement, the Patent Rights relate to certain patents relating to 3-Benzofuranyl-4-Indolyl Maleimides, the last
of which is scheduled to expire on March 16, 2028, not including any Patent Term Extension (“PTE”), which we may apply
for under Title II of the Drug Price Competition and Patent Term Restoration Act of 1984 (“Hatch-Waxman”), 35 U.S.C. §156.
The following summarizes the key terms set forth in the UIC License Agreement.
25
Pursuant to the UIC License Agreement,
UIC granted us (i) an exclusive, nontransferable license, with the right to sublicense under UIC’s rights in the Patent Rights,
and (ii) a non-exclusive, non-transferable license, with the right to sublicense, to use UIC’s rights in the Technical Information
within the specified territory (which is where the Patent Rights exist for such rights and worldwide for the Technical Information) for
all uses other than rights reserved by UIC for non-commercial purposes, including teaching, research and public service and publishing
information included in the Patent Rights and the Technical Information. The term of the UIC License Agreement continues in effect until
the later of (x) expiration of the last to expire of the Patent Rights, (y) notice from us that the use of the Technical Information
has ceased, and (z) the expiration of the last form of market exclusivity for products using the licensed technology. The UIC License
Agreement may also be earlier terminated by UIC in the event of certain breaches of its terms that are not cured following a notice period
or initiation of bankruptcy proceedings by or against us or the imposition of any lien or encumbrance on the licensed technology. We may
also terminate the UIC License Agreement for any reason following 90 days’ notice.
In consideration of the license
granted under the UIC License Agreement, we issued 46,528 shares of our common stock to UIC, which represented 5% of our capital stock
on a fully diluted basis as defined in the UIC License Agreement, and agreed to pay UIC (i) development milestones of up to $1.25 million,
of which, up to $0.25 million is due upon the progress of clinical trials and $1.0 million is due upon the initiation of commercial
sales (ii) annual minimum royalty payments of $5,000 beginning on the three-year anniversary of the UIC License Agreement and increasing
to $15,000 in year four, $35,000 in year five, and $50,000 in year six and thereafter, (iii) royalty on net sales for product covered
under the Patent Rights in the low single digits with a 50% reduction in royalties for products solely utilizing Technical Information,
(iv) a declining percentage of sublicensing revenue based on the escalating stage of development upon a sublicensing event,
and (v) the reimbursement of all patent and related expenses incurred by UIC covering the Patent Rights. We also agreed to customary
confidentiality and progress update obligations, to indemnify UIC for any claims arising from our use of the licensed rights under the
UIC License Agreement.
The UIC License Agreement obligates
us or a sublicensee to commercialize the licensed technology, including to achieve the development events specified in the agreement,
including progress through clinical trials and achieving commercialization. UIC may also identify feasible uses of the licensed technology
and, unless we demonstrate that we are pursuing such development or such development is not feasible within a specified period, UIC may
terminate the UIC License Agreement or the exclusivity of the licensed rights. As of the date hereof, we have met all existing milestones
as provided for in the UIC License Agreement. We are also responsible for the prosecution and maintenance of the licensed patents, at
our expense and using commercially reasonable efforts. We have the sole right to enforce the licensed patents, at our expense. The UIC
License Agreement terms are subject to the provisions of the Bayh-Dole Act, including requiring us to substantially manufacture products
related to the license in the United States, unless waived. While the DS for elraglusib is manufactured by a supplier in China, the end
drug product is substantially manufactured in the United States.
In addition, we entered into a
sublicense and collaboration agreement dated August 28, 2017 with an unrelated entity that was covered under the UIC License Agreement,
which sublicense agreement was later terminated on January 31, 2018. Under the UIC License Agreement, the Company owed UIC a certain percentage
of amounts received under the sublicense agreement in the amount of $449,990. The Company paid UIC 10% of the sublicense fees in the amount
of $44,999 and the remaining unpaid balance of $404,991 (“Deferred Amount”) was originally due and payable to UIC in two installments:
50% due and payable on the one-year anniversary from the first commercial sale and 50% due on the second-year anniversary from the first
commercial sale. The Deferred Amount is treated as debt and continues to accrue interest at a rate of five percent (5%) per annum, representing
the prime rate as of the date of the agreement plus 1%. On July 16, 2024, the Company and UIC entered an amendment to the UIC License
Agreement (“UIC Amendment”). Pursuant to the UIC Amendment, accrued interest is due and payable in two installments: (i) 50%
was due within 30 days following the closing of the Company’s IPO; and (ii) 50% is due within 30 days following the first anniversary
of the closing of the IPO. Thereafter, interest will be paid annually within 30 days following the second anniversary of the closing of
the IPO and annually thereafter. In addition, the UIC Amendment provides for payment of the Deferred Amount and any accrued interest thereon
upon the sooner of (i) termination of the UIC License Agreement by the Company, (ii) the Company ceases development of the licensed UIC
technology, (iii) the Company consummates a Change in Control (as defined in the UIC License Agreement), (iv) the Company sublicenses
the licensed technology or the developed product, (v) the one-year anniversary following approval of a NDA of a licensed product, or (vii)
the Company executes a partnership agreement with any entity resulting in the payment to us above a specified milestone amount or the
Company secures cumulative financing equal to or exceeding $200 million. In addition, the UIC Amendment provides that to the extent the
Company secures equity financing equal to or exceeding $85 million through its IPO or otherwise, 50% of the Deferred Amount is due and
payable within 30 days. The remaining 50% of the Deferred Amount shall be due and payable upon the first to occur of any of the events
noted above in clauses (i) through (vii). Finally, the UIC Amendment provides that for as long as the Company or a sublicensee is selling
the licensed product, the Company will pay all consideration provided for in the original UIC License Agreement and described above until
the last to expire market exclusivity date, the period of which for all products in a jurisdiction will not exceed a total of seven (7)
years beginning with the date regulatory approval is granted for the first licensed product in the jurisdiction, and such obligation will
survive termination of the UIC License Agreement.
26
Interest payable to UIC was $77,725
as of December 31, 2024, of which $70,957 is classified as current and $6,768 is classified as non-current, and are included in the accompanying
consolidated balance sheet. At December 31, 2023, accrued interest to UIC was $130,041, which is included in the accompanying consolidated
balance sheet.
Collaboration Agreement
We entered into a Collaboration
Agreement with Lantern Pharma in 2021 under which the parties are collaborating on utilization of Lantern Pharma’s platform to develop
novel biomarker derived signatures for use with our product candidates. As part of the collaboration, Lantern Pharma received 13,889 restricted
shares of our common stock, which vested upon meeting certain conditions of the collaboration, as well as the potential to receive additional
shares if results from the collaboration are utilized in future development efforts. Our former director, Les Kreis, Jr., was a director
of Lantern Pharma until June 8, 2022. Certain affiliates of the Bios Equity Affiliated Funds (as defined below), which is our largest
stockholder, beneficially owned greater than 10% of Lantern Pharma’s common stock as of December 31, 2024. Through December 31,
2024, no revenue has been recognized by either party under this agreement. Mr. Kreis was not involved in the negotiation of this
agreement and the negotiations were conducted at arm’s length.
Intellectual Property
The proprietary nature of, and
protection for, our product candidates and their methods of use and compositions of matter are an important part of our strategy to develop
and commercialize novel medicines, as described in more detail below. Our policy is to file patent applications to protect technology,
inventions and improvements to inventions that are commercially important to the development of our product candidates and our business.
We seek U.S. and foreign patent protection for a variety of technologies. We also intend to seek patent protection or rely upon trade
secret rights to protect other technologies that may be used to discover and validate targets and identify and develop novel products.
We seek protection, in part, through confidentiality and proprietary information agreements. We are a party to various other license agreements
that give us rights to use specific technologies in our research and development.
As of December 31, 2024,
we own or have licensed 88 issued patents and pending patent applications worldwide, including two pending international Patent Cooperation
Treaty (“PCT”) patent applications and four U.S. provisional patent applications, which are material to the programs described
in this Report. Three of these issued worldwide patents are owned by UIC, which has granted us exclusive license rights to the technology.
With respect to our elraglusib
program, as of December 31, 2024, we own or exclusively in-license one patent family focused on the elraglusib molecule and/or related
compounds. The exclusively in-licensed patent family for elraglusib and related compounds (the original patent in-licensed from UIC) includes
one granted U.S. patent, one granted European patent (with validation in 5 countries) and one granted Canadian patent, which are directed
to 3-Benzofuranyl-4-Indolyl Maleimides compounds. The U.S. patent is expected to expire in 2028.
Actuate subsequently discovered
that elraglusib exists as one of only two polymorphs and filed composition of matter patents covering both polymorphs. The patent family
covering “Polymorph I” is based on PCT/US2018/046203 9-ING-41 Polymorph I Composition of Matter and includes two granted patents
in the U.S. (US 11,136,334 and 12,145,943) and Mexico, one granted patent in each of Australia, China, Europe (with validation in 18 countries),
Japan, Israel, and South Korea, and pending patent applications in Australia, Brazil, Canada, China, Hong Kong, Israel, Japan, Macao,
South Korea, South Africa and the U.S., which are directed to a polymorph of a GSK-3β inhibitor, compounds, pharmaceutical compositions,
methods of preparing and uses for treating cancers. The U.S. patent is expected to expire in 2038.
The patent family we own that
covers elraglusib “Polymorph II” is based on PCT/US2018/056083 9-ING-41 Polymorph II Composition of Matter and includes two
granted U.S. patents (US 11,407,759 and 12,116,374), one granted patent in each of Australia, China, Mexico and Macao, and pending patent
applications in Brazil, Canada, the European Patent Office, Israel, Japan, South Korea, South Africa and the U.S., which are directed
to a polymorph of a GSK-3β inhibitor, compounds, pharmaceutical compositions, methods of preparing and uses for treating cancers.
The U.S. patent is expected to expire in 2038.
27
We intend to file additional patent
applications for the liquid and solid formulations of these elraglusib compositions covering the liquid and solid oral dosage forms of
elraglusib that we expect to develop.
The term of individual patents
depends upon the legal term of the patents in the countries in which they are obtained. In the United States, the patent term is 20 years
from the earliest date of filing a non-provisional patent application. In the United States, a patent’s term may be shortened if
a patent is terminally disclaimed over another patent or as a result of delays in patent prosecution by the patentee, and a patent’s
term may be lengthened by patent term adjustment, which compensates a patentee for administrative delays by the USPTO in granting a patent.
Patent term may also be extended up to five years due to regulatory delay (Patent Term Extension or “PTE”). We may apply
for PTE under Title II of the Hatch-Waxman Act for any one of the U.S. Patents, however there is no guarantee that PTE would be granted
for any patent.
We intend to continue to regularly
assess opportunities for seeking patent protection for those aspects of our discoveries that we believe provide a meaningful competitive
advantage. However, because patent filings can be time-consuming and expensive, our ability to do so may be limited until such time as
we are able to generate cash flow from operations or otherwise raise sufficient capital to continue to invest in our intellectual property.
For example, maintaining patents in the United States and other countries requires the payment of maintenance fees which, if we are unable
to pay, may result in loss of our patent rights. If we are unable to do so, our ability to protect our intellectual property or prevent
others from infringing our proprietary rights may be impaired.
Commercial Plan
We intend to retain significant
development and commercialization rights to our product candidates and, if marketing approval is obtained, to commercialize our product
candidates on our own, or potentially with a partner, in the United States and other regions. We currently have no sales, marketing and
commercial product distribution capabilities. We intend to build the necessary infrastructure and capabilities over time for the United
States, and potentially other regions, in connection with the advancement of our product candidates. Clinical data, the size of the addressable
patient population, the size of the commercial infrastructure and manufacturing needs, the status of our pipeline and other factors, may
all influence or alter our commercialization plans.
Manufacturing
We work with third-party suppliers
and manufacturers to support the manufacturing of elraglusib for clinical studies and our research activities and, if we receive regulatory
approval, we intend to rely on such third parties for commercial manufacture. We do not own or operate, and currently have no plans to
establish any manufacturing facilities. We currently obtain our investigational product from these third-party manufacturers on a purchase
order basis and do not have any long-term supply agreements in place. In order to de-risk our supply chain, and as we advance toward potential
commercialization, we may enter into long-term supply agreements as well as evaluate additional product manufacturing sources.
Competition
The biotechnology and pharmaceutical
industries, and the oncology sector in particular, are characterized by rapid evolution of technologies, fierce competition and strong
defense of intellectual property rights. While we believe that our development programs, technology, knowledge, experience and scientific
resources provide us with competitive advantages, we face competition from major pharmaceutical and biotechnology companies, academic
institutions, government agencies and public and private research institutions, among others.
Any product candidates that we
successfully develop and potentially commercialize will compete with currently approved therapies and new therapies that may become available
in the future. Key product features that would affect our ability to effectively compete with other therapeutics include the efficacy,
safety and convenience of our products.
28
Our most advanced clinical program
is being evaluated in a Phase 2 clinical trial as a first line treatment for mPDAC. The current standard first-line chemotherapies for
mPDAC include GnP, FOLFIRINOX (5-fluorouracil, leucovorin, irinotecan, and oxaliplatin) or NALIRIFOX (liposomal irinotecan, 5-fluorouracil,
leucovorin and oxaliplatin), and are associated with modest overall survival benefit.
We are presently developing elraglusib
in combination with GnP as a first-line treatment for mPDAC. In addition, we are also supporting an ongoing IIT that may provide exploratory
data on the combination of elraglusib and FOLFIRINOX as a first-line treatment for mPDAC. This may provide a rationale for developing
elraglusib in combination with FOLFIRINOX or NALIRIFOX as another first-line treatment for mPDAC. Patients with mPDAC either have primary
resistance to these chemotherapy backbones (e.g., do not respond at all when treated) or develop resistance quickly (responses with GnP,
FOLFIRINOX and NALIRIFOX are transient and not very durable). Our management believes that elraglusib may improve outcomes in first-line
mPDAC regardless of the chemotherapy backbone used, although the clinical data does not yet support this hypothesis. Nevertheless, since
either GnP or FOLFIRINOX are used to treat >90% of patients with mPDAC and there is potential for combining elraglusib with either
of these chemotherapy backbones based on our ongoing clinical studies, our management believes that elraglusib has the potential to treat
a large segment of patients diagnosed with mPDAC. Thus, our plan is to develop elraglusib in combination with the present first-line chemotherapy
regimens used in the treatment of mPDAC, as exemplified by its lead program of elraglusib/GnP and later moving to combinations with either
FOLFIRINOX or NALIRIFOX pending results of the IIT. If shown to be clinically meaningful, elraglusib chemotherapy combinations could eventually
be used to treat a large segment of patients with mPDAC.
Several other targeted therapies
are also being evaluated in Phase 3 in mPDAC. The panRAS inhibitor daraxonrasib (RMC-6236, Revolution Medicines, Inc.) is being evaluated
as a single agent in a Phase 3 trial (RASolute) in patients with previously untreated mPDAC. Arcus Biosciences, Inc. is also evaluating
their small molecule inhibitor of CD73 (quemliclustat), in combination with GnP in a Phase 3 trial (PRISM-1) also in patients with previously
untreated mPDAC. Both of these studies have only recently been initiated. There are other studies combining immune checkpoint inhibitors,
PARP inhibitors, various chemotherapies and other RAS inhibitors in patients with mPDAC including second-line studies. However, many of
the targeted agents besides elraglusib are only able to target a small percentage of mPDAC patients based on the presence of the target
or other genomic information. Ongoing studies with many of these agents in mPDAC are generally non-randomized at one or a limited number
of sites, are too early to assess for commercial potential and would not be considered as a competitor to elraglusib because of their
lack of broad suitability for most mPDAC patients. For example, the PARP inhibitor Lynparza (olaparib) was recently approved as a maintenance
therapy as it has been shown to significantly improve PFS and duration of response in patients with BRCA-mutated mPDAC who have not progressed
following first-line platinum-based chemotherapy. However, BRCA mutations are only present in 4-7% of all PDAC patients. Olaparib is currently
being evaluated as a therapeutic intervention in combination with a checkpoint inhibitor, pembrolizumab, in patients with mPDAC in BRCA1
mutated patients. Similarly, many of the RAS mutations targeted by clinical RAS inhibitors are only present in a low percentage of
all PDAC and thus, of the current PDAC inhibitors available in the clinic, few PDAC patients would be expected to benefit from their treatment.
Thus, the vast majority of mPDAC
patients still do not have an approved targeted therapy that can treat their tumor. If successful, we believe the elraglusib/chemotherapy
combination would introduce the first broadly targeted agent, elraglusib, as a treatment option for patients with mPDAC and would have
the potential to treat the majority (80-90%) of patients with mPDAC. A review of clinicaltrials.gov reveals that there are only a few
randomized studies for any novel drug or drug combination (not just targeted) in patients with mPDAC previously untreated for metastatic
disease:
· Onivyde® (Ipsen Pharma): Recently approved
for first-line mPDAC when used as part of the NALIRIFOX regimen based on a survival improvement of 1.9 months (NALIRIFOX 11.1 months
vs GNP 9.2 months).
· SBP-101 (Panbela Therapeutics, Inc.): A randomized,
double-blind, placebo-controlled, multicenter study of standard treatment with nab-paclitaxel and gemcitabine with or without SBP-101
in subjects previously untreated for mPDAC.
· Zolbetuximab (Astellas): A phase 2, open-label,
randomized study to assess the efficacy and safety of zolbetuximab (IMAB362) in combination with nab-paclitaxel and gemcitabine as first-line
treatment in subjects with claudin 18.2 (cldn18.2) positive, metastatic pancreatic adenocarcinoma.
· Mitazalimab (Alligator Pharmaceuticals): Phase
1b/2 study (OPTIMIZE-1) primary analysis was recently reported at ASCO 2024 (June 4, 2024). Mitazalimab is a CD40 agonist hypothesized
to overcome the suppressive immune environment in PDAC. OPTIMIZE-1 evaluated the combination of mitazalimab with mFOLFIRINOX in a single
arm study in patients with previously untreated mPDAC and met its ORR threshold >30% with an mOS of 14.3 months. Previous clinical
studies using the CD40 agonist sotigalimab combined with GnP in patients with previously untreated mPDAC did not meet its primary endpoint
of 1 year OS compared to a historical 1-year OS of 35%.
· RASolute- daraxonrasib (Revolution Medicines,
Inc.): To be determined (Not yet listed on the website www.clinicaltrials.gov).
· PRISM-1- quemliclustat (Arcus Biosciences, Inc.):
A randomized, placebo-controlled, double-blind, Phase 3 trial of quemliclustat and chemotherapy versus placebo and chemotherapy in patients
with treatment-naive mPDAC. This study was only recently initiated.
29
There are several treatments in
development for locally advanced or mPDAC. The information cited above focuses only on select first-line treatments that are in clinical
trials in mPDAC. Quite a few of these are very early stage and therefore little information is available on clinical activity to date.
With the initial success of biomarker driven and targeted therapies, there is an effort to test additional targeted agents in mPDAC patients
to determine if there is any synergy with standard chemotherapy regimens in the first-line setting. For instance, KRAS is mutated in over
90% of pancreatic cancer patients and there are several KRAS targeted agents in development; however, several agents are specifically
targeting the G12C mutation which only accounts for 1-2% of KRAS mutations in pancreatic cancer. Other agents are being tested in KRAS
mutant cancers more broadly by targeting other MAPK pathway members such as MEK and ERK1/2, though treatment-related toxicity has been
reported with these agents. Additionally, these MAPK targeted agents are currently being evaluated in second-line and later settings.
In the future, targeted/ immunotherapy agents may be able to be combined or used in series to provide a more flexible and tailored therapeutic
approach for each individual patient. Additionally, the multifaceted and differentiated mechanism of action of elraglusib is likely to
be synergistic with both cytotoxic and immunomodulatory therapeutics that may be approved in the future. Our management believes that
this potential for combining elraglusib with future multi-therapy regimens is also feasible given favorable safety profile of elraglusib
as a single agent. Mechanistically, some of the targets inhibited by competitors (e.g., KRAS) intersect with the GSK-3 pathways and provide
a rationale for potentially prioritizing these combinations with elraglusib in the future.
The above information includes
corporate competitors that we are currently aware of and are currently conducting clinical trials or marketing in geographies where we
currently anticipate conducting clinical trials for our product candidate. However, companies operating in other geographies and smaller
and other early-stage companies may also prove to be significant competitors. In addition, academic research departments and public and
private research institutions may be conducting research on compounds that could prove to be competitive.
Finally, many of the companies
against which we may compete have significantly greater financial resources and expertise in research and development, manufacturing,
preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. Smaller or
early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established
companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel, establishing
clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary
for, our programs.
Government Regulation and Product Approval
Government authorities in the
United States, at the federal, state and local level, and other countries extensively regulate, among other things, the research, development,
testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, post-approval
monitoring and reporting, marketing and export and import of products such as those we are developing. The pharmaceutical product candidates
that we develop must be approved by the FDA before they may be legally marketed in the United States. See “Risk Factors — Risks
Related to Clinical Development and Regulatory Approval.”
U.S. Pharmaceutical Product Development Process
In the United States, the FDA
regulates pharmaceutical products under the Federal Food, Drug and Cosmetic Act (“FDCA”) and implementing regulations. Pharmaceutical
products are also subject to other federal, state and local statutes and regulations. The process of obtaining regulatory approvals and
the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial
time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product development process,
approval process or after approval, may subject an applicant to administrative or judicial enforcement. Any regulatory enforcement action
could have a material adverse effect on us. The process required by the FDA before a non-biological pharmaceutical product may be marketed
in the United States generally involves the following:
· Completion of preclinical laboratory tests, animal
studies and formulation studies according to Good Laboratory Practices (“GLP”), and other applicable regulations;
· Submission of an Investigational New Drug application
(“IND”), which must become effective before human clinical studies may begin;
· Conduct of adequate and well-controlled human
clinical studies according to current Good Clinical Practices (“GCP”), to establish the safety and efficacy of the proposed
pharmaceutical product for its intended use;
· Submission to the FDA of an NDA for a new pharmaceutical
product;
· Satisfactory completion of an FDA inspection
of the manufacturing facility or facilities where the pharmaceutical product is produced to assess compliance with current Good Manufacturing
Practice standards (“cGMP”), to assure that the facilities, methods and controls are adequate to preserve the pharmaceutical
product’s identity, strength, quality and purity;
· Potential FDA inspection of the preclinical and
clinical study sites that generated the data in support of the NDA; and
· FDA review and approval of the NDA.
30
The lengthy process of seeking
required approvals and the continuing need for compliance with applicable statutes and regulations require the expenditure of substantial
resources and approvals are inherently uncertain.
Before testing any pharmaceutical
product with potential therapeutic value in humans, the pharmaceutical product candidate enters the preclinical testing stage. Preclinical
tests include laboratory evaluations of product chemistry, toxicity and formulation, as well as animal studies to assess the potential
safety and activity of the pharmaceutical product candidate. These early studies are conducted using sound scientific procedures and require
thorough documentation. The conduct of a single and repeat dose toxicology and toxicokinetic studies in animals must comply with federal
regulations and requirements including GLP. The pharmaceutical product sponsor must submit the results of the preclinical tests, together
with manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the FDA
as part of the IND. The IND becomes effective 30 days after receipt by the FDA, unless the FDA has concerns and notifies the sponsor.
In such a case, the IND sponsor must resolve any outstanding concerns before the clinical study can begin. If resolution cannot be reached
within the 30-day review period, the FDA can place the IND on clinical hold or the sponsor may withdraw the application. The FDA may also
impose clinical holds on a pharmaceutical product candidate at any time before or during clinical studies due to safety concerns or regulatory
non-compliance. Accordingly, it is not certain that submission of an IND will result in the FDA allowing clinical studies to begin, or
that, once begun, issues will not arise that can lead to suspension or termination of such clinical studies.
During the development of a new
drug, sponsors are given opportunities to meet with the FDA to discuss progress. These meetings may occur prior to submission of an IND,
at the end of Phase 2 clinical development, and before an NDA is submitted. Meetings at other times may be requested. These meetings
can provide an opportunity for the sponsor to share information about the data gathered to date, for the sponsor to ask specific questions
of the FDA, for the FDA to provide advice, and for the sponsor and FDA to reach agreement on the next phase of development. Sponsors typically
use the end of Phase 2 meeting to discuss their Phase 2 clinical results and present their plans for the pivotal Phase 3
clinical (registration) trial(s) that they believe will support approval of the new drug. A sponsor may be able to request a Special Protocol
Assessment (“SPA”), the purpose of which is to reach agreement with the FDA on the Phase 3 clinical trial protocol design
and analyses that will form the primary basis of an efficacy claim.
Conducting Clinical Studies
Clinical studies are voluntary
research studies involving the administration of the pharmaceutical product candidate to healthy volunteers or patients under the supervision
of qualified investigators, typically physicians independent of the clinical study sponsor’s control. Clinical studies are conducted
according to protocols detailing, among other things, the objectives of the clinical study, dosing procedures, subject selection and exclusion
criteria, how the results will be analyzed and presented and the parameters to be used to monitor subject safety. Each protocol must be
submitted to the FDA as part of the IND. Clinical studies must be conducted in accordance with GCP requirements. Further, each clinical
study must be reviewed and approved by an independent institutional review board (“IRB”), at, or servicing, each institution
at which the clinical study will be conducted. An IRB is charged with protecting the welfare and rights of study participants and is tasked
with considering such items as whether the safety risks to individuals participating in the clinical studies are minimized and are reasonable
in relation to anticipated benefits. The IRB approves the informed consent that must be provided to each clinical study subject or his
or her legal representative and will also monitor the clinical study to ensure patient safety until completed.
31
Human clinical studies are typically
conducted in three sequential phases that may overlap or be combined:
· Phase 1. The pharmaceutical product
is initially administered to healthy volunteers and tested for safety, dosage tolerance, absorption, metabolism, distribution and excretion.
· Phase 2. The pharmaceutical product
is studied in a limited patient population with the disease or condition to evaluate its effectiveness for a particular indication or
indications and to determine the common short-term side effects and risks associated with the product.
· Phase 3. Clinical studies are undertaken
to further evaluate dosage, clinical efficacy and safety in an expanded patient population at geographically dispersed clinical study
sites. These clinical studies are intended to establish the overall risk/benefit of the product and provide an adequate basis for product
labeling. The studies must be well-controlled and usually include a control arm for comparison. One or two Phase 3 studies may be
required by the FDA for an NDA, depending on the disease severity and other available treatment options.
· Post-approval studies, or Phase 4 clinical
studies, may be conducted after initial marketing approval. These studies are used to gain additional experience from the treatment of
patients in the intended therapeutic indication.
· Progress reports detailing the results of the
clinical studies must be submitted at least annually to the FDA and written IND safety reports must be submitted to the FDA and the investigators
for serious and unexpected adverse events or any finding from tests in laboratory animals that suggests a significant risk for human subjects.
Phase 1, Phase 2 and Phase 3 clinical studies may not be completed successfully within any specified period, if at all.
The FDA, the sponsor or its data safety monitoring board may suspend a clinical study 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 study at its institution if the clinical study is not being conducted in accordance with the IRB’s requirements or
if the pharmaceutical product has been associated with unexpected serious harm to patients.
Concurrent with clinical studies,
companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics
of the pharmaceutical product as well as finalize a process for manufacturing the product in commercial quantities in accordance with
cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the pharmaceutical product candidate
and, among other things, must include methods for testing the identity, strength, quality and purity of the final pharmaceutical product.
Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the pharmaceutical
product candidate does not undergo unacceptable deterioration over its shelf life.
U.S. Review and Approval Processes
The results of product development,
preclinical studies and clinical studies, along with descriptions of the manufacturing process, analytical tests conducted on the chemistry
of the pharmaceutical product, proposed labeling and other relevant information are submitted to the FDA as part of an NDA requesting
approval to market the product. The submission of an NDA is subject to the payment of substantial user fees; a waiver of such fees may
be obtained under certain limited circumstances.
In addition, under the Pediatric
Research Equity Act (“PREA”), an NDA or a supplement thereof must contain data to assess the safety and effectiveness of the
pharmaceutical product for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for
each pediatric subpopulation for which the product is safe and effective. The FDA may grant deferrals for submission of data or full or
partial waivers. Unless otherwise required by regulation, PREA does not apply to any pharmaceutical product for an indication for which
orphan designation has been granted. The FDA reviews all NDAs submitted before it accepts them for filing and may request additional information
rather than accepting an NDA for filing. Once the submission is accepted for filing, the FDA begins an in-depth review of the NDA. Under
the goals and policies agreed to by the FDA under the Prescription Drug User Fee Act (“PDUFA”), the FDA has 10 months
in which to complete its initial review of a standard NDA and respond to the applicant, and six months for a priority NDA. The FDA
does not always meet its PDUFA goal dates for standard and priority NDAs. The review process and the PDUFA goal date may be extended by
three months if the FDA requests or if the NDA sponsor otherwise provides additional information or clarification regarding information
already provided in the submission within the last three months before the PDUFA goal date.
32
After the NDA submission is accepted
for filing, the FDA reviews the NDA application to determine, among other things, whether the proposed product is safe and effective for
its intended use, and whether the product is being manufactured in accordance with cGMP to assure and preserve the product’s identity,
strength, quality and purity. The FDA may refer applications for novel pharmaceutical products or pharmaceutical products which present
difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for
review, evaluation and a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound
by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions. During the pharmaceutical
product approval process, the FDA also will determine whether a risk evaluation and mitigation strategy (“REMS”), is necessary
to assure the safe use of the pharmaceutical product. If the FDA concludes that a REMS is needed, the sponsor of the NDA must submit a
proposed REMS; the FDA will not approve the NDA without a REMS, if required.
Before approving an NDA, the FDA
will inspect the facilities at which the product is manufactured. The FDA will not approve the product unless it determines that the manufacturing
processes and facilities are in compliance with cGMP requirements and adequate to ensure consistent production of the product within required
specifications.
Additionally, before approving
an NDA, the FDA will typically inspect one or more clinical study sites to assure compliance with GCPs. If the FDA determines the application,
manufacturing process or manufacturing facilities, or clinical study sites are not acceptable, it will outline the deficiencies in the
submission and often will request additional testing or information. In addition, the FDA will require the review and approval of product
labeling.
The NDA review and approval process
is lengthy and involved and the FDA may refuse to approve an NDA if the applicable regulatory criteria are not satisfied or may require
additional clinical data or other data and information. Even if such data and information are submitted, the FDA may ultimately decide
that the NDA does not satisfy the criteria for approval. Data obtained from clinical studies are not always conclusive and the FDA may
interpret data differently than the sponsor interprets the same data. The FDA will issue a complete response letter if the agency decides
not to approve the NDA. The complete response letter usually describes all of the specific deficiencies in the NDA identified by the FDA.
The deficiencies identified may be minor, for example, requiring labeling changes, or major, for example, requiring additional clinical
studies.
Additionally, the complete response
letter may include recommended actions that the applicant might take to place the application in a condition for approval. If a complete
response letter is issued, the applicant may either resubmit the NDA, addressing all of the deficiencies identified in the letter, or
withdraw the application.
If a product receives regulatory
approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited,
which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings or precautions
be included in the product labeling. In addition, the FDA may require Phase 4 testing which involves clinical studies designed to
further assess pharmaceutical product safety and effectiveness and may require testing and surveillance programs to monitor the safety
of approved products that have been commercialized.
Expedited Development and Review Programs; Breakthrough Therapy Designation
The FDA has a Fast Track program
that is intended to expedite or facilitate the process for reviewing new pharmaceutical products that meet certain criteria. Specifically,
new pharmaceutical 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. The Fast Track designation must be requested by the sponsor.
Fast Track designation applies to the combination of the product and the specific indication for which it is being studied. With a Fast
Track designated product, the FDA may consider for review sections of the NDA on a rolling basis before the complete application is submitted,
if the sponsor provides a schedule for the submission of the sections of the NDA, if the FDA agrees to accept sections of the NDA and
determines that the schedule is acceptable and if the sponsor pays any required user fees upon submission of the first section of the
NDA.
33
Any product submitted to the FDA
for marketing approval, including a Fast Track program, may also be eligible for other types of FDA programs intended to expedite development
and review, such as priority review and accelerated approval. Any product is eligible for priority review if it has the potential to provide
safe and effective therapy where no satisfactory alternative therapy exists or a significant improvement in the treatment, diagnosis or
prevention of a disease compared to marketed products. The FDA will attempt to direct additional resources to the evaluation of an application
for a new pharmaceutical product designated for priority review in an effort to facilitate the review. Additionally, a product may be
eligible for accelerated approval. Pharmaceutical 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, which means that
the products may be approved on the basis of adequate and well-controlled clinical studies establishing that the product has an effect
on a surrogate endpoint that is reasonably likely to predict a clinical benefit, or on the basis of an effect on a clinical endpoint other
than survival or irreversible morbidity. As a condition of approval, the FDA may require that a sponsor of a pharmaceutical product receiving
accelerated approval perform adequate and well-controlled post-marketing clinical studies. In addition, the FDA currently requires as
a condition for accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the commercial
launch of the product. Fast Track designation, priority review and accelerated approval do not change the standards for approval but may
expedite the development or approval process.
The FDA is also required to expedite
the development and review of the application for approval of drugs that are intended to treat a serious or life-threatening disease or
condition where preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies
on one or more clinically significant endpoints. Under the breakthrough therapy program, the sponsor of a new product candidate may request
that the FDA designate the product candidate for a specific indication as a breakthrough therapy concurrent with, or after, the filing
of the IND for the product candidate. The FDA must determine if the product candidate qualifies for breakthrough therapy designation within
60 days of receipt of the sponsor’s request. Elraglusib IV and elraglusib oral dosage forms may all be eligible for breakthrough
therapy designation depending on the indication and pending additional data.
Orphan Drug Designation
Under the Orphan Drug Act, the
FDA may grant orphan designation to a drug intended to treat a rare disease or condition affecting fewer than 200,000 individuals in the
United States, or in other limited cases. ODD provides for seven years of market exclusivity, independent of patent protection, to
the company with ODD that brings a particular product to market. In addition, companies developing orphan drugs are eligible for certain
incentives, including tax credits for qualified clinical testing.
To gain exclusivity, if a product
that has ODD subsequently receives the first FDA approval for the disease or condition for which it has such designation, the product
is entitled to the orphan drug exclusivity, which means that the FDA may not approve any other applications to market the same active
moiety for the same indication for seven years, except in limited circumstances, such as another drug’s showing of clinical
superiority over the drug with orphan exclusivity. In addition, doctors may prescribe products for off-label uses and undermine our exclusivity.
Orphan drug exclusivity could block the approval of one of our product candidates for seven years if a competitor obtains approval
for the same active moiety for the same indication before we do, unless we are able to demonstrate that our product is clinically superior.
A sponsor may request ODD of a
previously unapproved product or new orphan indication for an already marketed product. In addition, a sponsor of a product that is otherwise
the same product as an already approved orphan drug may seek and obtain ODD for the subsequent product for the same rare disease or condition
if it can present a plausible hypothesis that its product may be clinically superior to the first, approved product. More than one sponsor
may receive ODD for the same product for the same rare disease or condition, but each sponsor seeking ODD must file a complete request
for designation, and only the first sponsor that obtains approval for that drug for the orphan indication will obtain market exclusivity,
effectively preventing the FDA from approving products under development by competitors for the same drug and same indication, unless
the competitor is able to demonstrate that the product under development is clinically superior to the approved product or the approved
product is not available in sufficient quantities. To permit the FDA to end another manufacturer’s orphan exclusivity period, the
FDA must determine that the manufacturer has demonstrated clinical superiority by showing the later drug is safer, more effective, or
otherwise makes a major contribution to patient care.
We may plan to pursue ODD and
exclusivity for some of our product candidates in the United States, the EU, and other geographies of interest for specific products.
ODD neither shortens the development time or regulatory review time of a drug nor gives the drug any advantage in the regulatory review
or approval process. We cannot guarantee that we will obtain ODD for any products in any jurisdiction. Even if we are able to acquire
ODD for a product, we cannot be sure that such product will be approved, that we will be able to obtain orphan drug exclusivity upon approval,
if ever, or that we will be able to maintain any exclusivity that is granted.
34
Regulation Outside the United States
In order to market a pharmaceutical
product outside of the United States, a company must also comply with numerous and varying regulatory requirements of other countries
and jurisdictions regarding quality, safety and efficacy that govern, among other things, clinical trials, marketing authorization, commercial
sales and distribution. Whether or not we obtain FDA approval for a pharmaceutical product, we would need to obtain the necessary approvals
by the comparable non-U.S. regulatory authorities before it can commence clinical trials or marketing of the product in those countries
or jurisdictions. The approval process ultimately varies between countries and jurisdictions and can involve additional product testing
and additional administrative review periods. The time required to obtain approval in other countries and jurisdictions might differ from
and be longer than that required to obtain FDA approval. Regulatory approval in one country or jurisdiction does not ensure regulatory
approval in another, but a failure or delay in obtaining regulatory approval in one country or jurisdiction may negatively impact the
regulatory process in others.
Regulation and Marketing Authorization in the EU
The EMA is the scientific agency
of the EU that coordinates the evaluation and monitoring of new and approved medicinal products such as drugs and biologics. It is responsible
for the scientific evaluation of applications for EU marketing authorizations, as well as the development of technical guidance and the
provision of scientific advice to sponsors.
The process regarding approval
of medicinal products in the EU follows roughly the same lines as in the United States and likewise generally involves satisfactorily
completing each of the following:
· preclinical laboratory tests, animal studies
and formulation studies all performed in accordance with the applicable EU Good Laboratory Practice regulations;
· submission to the relevant regulatory agencies
in EU member states, or national authorities, of a clinical trial application (“CTA”) for each clinical trial, which must
be approved before human clinical trials may begin;
· performance of adequate and well-controlled clinical
trials to establish the safety and efficacy of the product for each proposed indication;
· submission to the relevant national authorities
of a Marketing Authorization Application (“MAA”), which includes the data supporting safety and efficacy as well as detailed
information on the manufacture and composition of the product in clinical development and proposed labeling;
· satisfactory completion of an inspection by the
relevant national authorities of the manufacturing facility or facilities, including those of third parties, at which the product is produced
to assess compliance with cGMP;
· potential audits of the non-clinical and clinical
trial sites that generated the data in support of the MAA; and
· review and approval by the relevant national
authority of the MAA before any commercial marketing, sale or shipment of the product.
Preclinical Studies
Preclinical tests include laboratory
evaluations of product chemistry, formulation and stability, as well as studies to evaluate the potential efficacy and toxicity in animals.
The conduct of the preclinical tests and formulation of the compounds for testing must comply with the relevant EU regulations and requirements.
The results of the preclinical tests, together with relevant manufacturing information and analytical data, are submitted as part of the
CTA when seeking approval to start a clinical trial, and with the MAA when seeking marketing authorization.
Clinical Trial Approval
Requirements for the conduct of
clinical trials in the EU including GCP, are implemented in the current Clinical Trials Directive 2001/20/EC and the GCP Directive 2005/28/EC.
Pursuant to Directive 2001/20/EC and Directive 2005/28/EC, as amended, a system for the approval of clinical trials in the EU has been
implemented through national legislation of the EU member states. Under this system, approval must be obtained from the competent national
authority in which a trial is planned to be conducted, or in multiple member states if the clinical trial is to be conducted in a number
of member states. To this end, a CTA is submitted, which must be supported by an investigational medicinal product dossier (IMPD) and
further supporting information prescribed by Directive 2001/20/EC and Directive 2005/28/EC and other applicable guidance documents. Furthermore,
a clinical trial may only be started after a competent ethics committee has issued a favorable opinion on the clinical trial application
in that country.
35
On January 31, 2022, the
Clinical Trials Regulation (EU) No. 536/2014 repealed the Clinical Trials Directive 2001/20/EC. To ensure that the rules for clinical
trials are identical throughout the EU, the Clinical Trials Regulation (EU) No. 536/2014 was passed as a regulation which is directly
applicable in all EU member states. The Clinical Trials Directive 2001/20/EC will, however, still apply three years from the
date of entry into application of the Clinical Trials Regulation to (i) clinical trials applications submitted before the entry into
application and (ii) clinical trials applications submitted within one year after the entry into application if the sponsor opts
for the old system.
Regulation (EU) No 536/2014 aims
to simplify and streamline the approval of clinical trial in the EU. The main characteristics of the regulation include:
· a streamlined application procedure via a single
entry point, known as the Clinical Trials Information System;
· a single set of documents to be prepared and
submitted for the application as well as simplified reporting procedures which will spare sponsors from submitting broadly identical information
separately to various and different national authorities;
· harmonized procedure for the assessment of applications
for clinical trials, which is divided in two parts;
· strictly defined deadlines for the assessment
of clinical trial application; and
· the involvement of the ethics committees in the
assessment procedure in accordance with the national law of the member state concerned but within the overall timelines defined by the
Regulation (EU) No 536/2014.
Marketing Authorization
Authorization to market a product
in the member states of the EU proceeds under one of four procedures: a centralized procedure, a mutual recognition procedure, a decentralized
procedure or a national procedure.
Centralized Procedure
The centralized procedure enables
applicants to obtain a marketing authorization that is valid in all EU member states based on a single application. Certain medicinal
products, including products developed by means of biotechnological processes, must undergo the centralized authorization procedure for
marketing authorization, which, if granted by the European Commission, based on the opinion of the EMA, is automatically valid in all
EU member states. Sponsors may elect to file an MAA through the centralized procedures for other classes of products.
The centralized procedure is mandatory
for certain types of products such as medicines derived from biotechnology processes (e.g., genetic engineering), advanced-therapy medicines
(e.g., gene-therapy, tissue engineered medicine), orphan medicines, and medicinal products containing a new active substance indicated
for the treatment of HIV, AIDS, cancer, diabetes, neurodegenerative disorders, autoimmune and other immune dysfunctions, and viral diseases.
The centralized authorization
procedure is optional for other medicinal products if they contain a new active substance, if the applicant shows that the medicinal product
concerned constitutes a significant therapeutic, scientific or technical innovation, or that the granting of authorization is in the public
interest of the EU.
36
Administration Procedure
Under the centralized procedure,
the EMA’s Committee for Human Medicinal Products (“CHMP”) serves as the scientific committee that renders opinions about
the safety, efficacy and quality of medicinal products for human use on behalf of the EMA. The CHMP is composed of experts nominated by
each member state’s national authority for medicinal products, with one of them appointed to act as Rapporteur for the coordination
of the evaluation with the possible assistance of a further member of the Committee acting as a Co-Rapporteur. After approval, the Rapporteur(s)
continue to monitor the product throughout its life cycle. The CHMP has 210 active days, to adopt an opinion as to whether a marketing
authorization should be granted. The process usually takes longer in case additional information is requested, which triggers clock-stops
in the procedural timelines. The process is complex and involves extensive consultation with the regulatory authorities of member states
and a number of experts. When an application is submitted for a marketing authorization in respect of a drug which is of major interest
from the point of view of public health and in particular from the viewpoint of therapeutic innovation, the applicant may, pursuant to
Article 14(9) Regulation (EC) No 726/2004, request an accelerated assessment procedure. If the CHMP accepts such request, the time-limit
of 210 days will be reduced to 150 days, but it is possible that the CHMP can revert to the standard time-limit for the centralized
procedure if it considers that it is no longer appropriate to conduct an accelerated assessment. Once the procedure is completed, a European
Public Assessment Report (“EPAR”) is produced. If the opinion is negative, information is given as to the grounds on which
this conclusion was reached. After the adoption of the CHMP opinion, a decision on the MAA must be adopted by the European Commission,
after consulting the EU member states, which in total can take more than 60 days. After a drug has been authorized and launched,
it is a condition of maintaining the marketing authorization that all aspects relating to its quality, safety and efficacy must be kept
under review.
Conditional Approval
In specific circumstances, EU
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 products (including
medicines designated as orphan medicinal products), if (1) the risk-benefit balance of the product 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 and/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.
Marketing Authorization Under Exceptional Circumstances
As per Article 14(8) Regulation
(EC) No 726/2004, products for which the applicant can demonstrate that comprehensive data (in line with the requirements laid down in
Annex I of Directive 2001/83/EC, as amended) cannot be provided (due to specific reasons foreseen in the legislation) might be eligible
for marketing authorization under exceptional circumstances. This type of authorization is reviewed annually to reassess the risk-benefit
balance. The fulfillment of any specific procedures/obligations imposed as part of the marketing authorization under exceptional circumstances
is aimed at the provision of information on the safe and effective use of the product and will normally not lead to the completion of
a full dossier/approval.
37
Pediatric Studies
Prior to obtaining a marketing
authorization in the EU, applicants have to demonstrate compliance with all measures included in an EMA-approved Pediatric Investigation
Plan (“PIP”) covering all subsets of the pediatric population, unless the EMA has granted (1) a product-specific waiver,
(2) a class waiver, or (3) a deferral for one or more of the measures included in the PIP. The respective requirements for all
marketing authorization procedures are laid down in Regulation (EC) No 1901/2006, the so-called Pediatric Regulation. This requirement
also applies when a company wants to add a new indication, pharmaceutical form or route of administration for a medicine that is already
authorized. The Pediatric Committee of the EMA (“PDCO”) may grant deferrals for some medicines, allowing a company to delay
development of the medicine in children until there is enough information to demonstrate its effectiveness and safety in adults. The PDCO
may also grant waivers when development of a medicine in children is not needed or is not appropriate, such as for diseases that only
affect the elderly population.
Before a marketing authorization
application can be filed, or an existing marketing authorization can be amended, the EMA determines that companies actually comply with
the agreed studies and measures listed in each relevant PIP.
Period of Authorization and Renewals
A marketing authorization will
be 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 a national authority. 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 nine months before the marketing authorization ceases to be valid.
Once renewed, the marketing authorization will be valid for an unlimited period, unless the European Commission or the national authority
decides on justified grounds relating to pharmacovigilance, to proceed with one additional five-year renewal. Any authorization that is
not followed by the actual placing of the drug on the EU market (in case of centralized procedure) or on the market of the authorizing
member state within three years after authorization will cease to be valid, the so-called “sunset clause.”
Orphan Medicinal Product Designation and Exclusivity
The European Commission can grant
OMPD to products for which the sponsor can establish that it is intended for the diagnosis, prevention, or treatment of (1) a life-threatening
or chronically debilitating condition affecting not more than five in 10,000 people in the EU, or (2) a life threatening, seriously
debilitating or serious and chronic condition in the EU and that without incentives it is unlikely that sales of the drug in the EU would
generate a sufficient return to justify the necessary investment. In addition, the sponsor must establish that there is no other satisfactory
method approved in the EU of diagnosing, preventing or treating the condition, or if such a method exists, the proposed orphan drug will
be of significant benefit to patients.
OMPD provides a number of benefits,
including fee reductions, regulatory assistance, and the possibility to apply for a centralized EU marketing authorization, as well as
10 years of market exclusivity following a marketing authorization. During this market exclusivity period, neither the EMA, nor the
European Commission nor the Member States can accept an application or grant a marketing authorization for a medicinal product containing
a similar active substance or substances as contained in an authorized orphan medicinal product, and which is intended for the same therapeutic
indication. The market exclusivity period for the authorized therapeutic indication may be reduced to six years if, at the end of
the fifth year, it is established that the OMPD criteria are no longer met, including where it is shown that the product is sufficiently
profitable not to justify maintenance of market exclusivity. In addition, a competing similar medicinal product may be authorized prior
to the expiration of the market exclusivity period, including if it is shown to be safer, more effective or otherwise clinically superior
to the already approved orphan drug or if the holder of the marketing authorization for the already approved orphan drug is unable to
supply sufficient quantities of the product.
If the MAA of a medicinal product
designated as an orphan drug includes the results of all studies conducted in compliance with an agreed PIP, and a corresponding statement
is subsequently included in the marketing authorization granted, the 10-year period of market exclusivity will be extended to 12 years.
38
Regulatory Data Protection
EU legislation also provides for
a system of regulatory data and market exclusivity. Upon receiving marketing authorization, new chemical entities approved on the basis
of complete independent data package benefit from eight years of data exclusivity and an additional two years of market exclusivity.
Data exclusivity prevents regulatory authorities in the EU from referencing the innovator’s data to assess a generic or biosimilar
(abbreviated) application. During the additional two-year period of market exclusivity, a generic or biosimilar marketing authorization
can be submitted, and the innovator’s data may be referenced, but no generic or biosimilar medicinal product can be marketed until
the expiration of the market exclusivity. The overall 10-year period will be extended to a maximum of 11 years if, during the first
8 years of those 10 years, the marketing authorization holder (“MAH”) 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. Even if a compound is considered to be a new chemical entity and the innovator is able
to gain the period of data exclusivity, another company nevertheless could also market another version of the drug if such company obtained
marketing authorization based on an MAA with a complete independent data package of pharmaceutical test, preclinical tests and clinical
trials. However, products designated as orphan medicinal products enjoy, upon receiving marketing authorization, a period of 10 years
of orphan market exclusivity. Depending upon the timing and duration of the EU marketing authorization process, products may be eligible
for up to five years’ supplementary protection certificates (“SPCs”). Such SPCs extend the rights under the basic
patent for the drug.
Regulatory Requirements After a Marketing Authorization Has Been Obtained
If we obtain authorization for
a medicinal product in the EU, we will be required to comply with a range of requirements applicable to the manufacturing, marketing,
promotion and sale of medicinal products.
We will, for example, have to
comply with the EU’s stringent pharmacovigilance or safety reporting rules, pursuant to which post-authorization studies and additional
monitoring obligations can be imposed.
Other requirements relate to,
for example, the manufacturing of products and active pharmaceutical ingredients in accordance with good manufacturing practice standards.
EU regulators may conduct inspections to verify our compliance with applicable requirements, and we will have to continue to expend time,
money and effort to remain compliant. Non-compliance with EU requirements regarding safety monitoring or pharmacovigilance, and with requirements
related to the development of products for the pediatric population, can also result in significant financial penalties in the EU. Similarly,
failure to comply with the EU’s requirements regarding the protection of individual personal data can also lead to significant penalties
and sanctions. Individual EU member states may also impose various sanctions and penalties in case we do not comply with locally applicable
requirements.
The manufacturing of authorized
drugs, for which a separate manufacturer’s license is mandatory, must be conducted in compliance with the EMA’s cGMP requirements
and comparable requirements of other national authorities, which mandate the methods, facilities and controls used in manufacturing, processing
and packing of drugs to assure their safety and identity. The EMA enforces its cGMP requirements through mandatory registration of facilities
and inspections of those facilities. The EMA may have a coordinating role for these inspections while the responsibility for carrying
them out rests with the member states competent authority under whose responsibility the manufacturer falls. Failure to comply with these
requirements could interrupt supply and result in delays, unanticipated costs and lost revenues, and could subject the applicant to potential
legal or regulatory action, including but not limited to warning letters, suspension of manufacturing, seizure of product, injunctive
action or possible civil and criminal penalties.
The marketing and promotion of
authorized drugs, including industry-sponsored continuing medical education and advertising directed toward the prescribers of drugs and/or
the general public, are strictly regulated in the EU. The applicable regulations aim to ensure that information provided by holders of
marketing authorizations regarding their products is truthful, balanced and accurately reflects the safety and efficacy claims authorized
by the EMA or by the national authority of the authorizing member state. Failure to comply with these requirements can result in adverse
publicity, warning letters, corrective advertising and potential civil and criminal penalties.
39
Other Healthcare Laws
In addition to FDA restrictions
on marketing of pharmaceutical products, several other types of state and federal laws have been applied to restrict certain business
practices in the biopharmaceutical industry. Applicable federal and state healthcare laws and regulations include the following:
· The federal healthcare Anti-Kickback Statute
of 1972 prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving, or providing remuneration,
directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, order, or recommendation
of, any good or service, for which payment may be made under federal healthcare programs such as Medicare, Medicaid, or other governmental
programs. A person or entity does not need to have actual knowledge of the federal anti-kickback statute or specific intent to violate
it to have committed a violation; in addition, items or services resulting from a violation of the federal anti-kickback statute may constitute
a false or fraudulent claim for purposes of the False Claims Act;
· The federal False Claims Act of 1986 imposes
criminal and civil penalties, including civil whistleblower or qui tam actions, against individuals or entities for knowingly presenting,
or causing to be presented, to the federal government claims for payment that are false or fraudulent or making a false statement to avoid,
decrease, or conceal an obligation to pay money to the federal government;
· The Health Insurance Portability and Accountability
Act of 1996 (“HIPAA”), imposes criminal and civil liability for executing a scheme to defraud any healthcare benefit program
and also imposes obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission
of individually identifiable health information. This statute also prohibits knowingly and willfully falsifying, concealing or covering
up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items,
or services;
· HIPAA, as amended by the Health Information Technology
for Economic and Clinical Health Act (“HITECH”) of 2009 and its implementing regulations, imposes certain requirements relating
to the privacy, security and transmission of individually identifiable health information. Among other things, HITECH makes HIPAA’s
privacy and security standards directly applicable to “business associates” — independent contractors
or agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of
a covered entity.
· The Medicare Prescription Drug, Improvement and
Modernization Act of 2003 (MMA) imposed new requirements for the distribution and pricing of prescription drugs for Medicare beneficiaries.
Under Part D, Medicare beneficiaries may enroll in prescription drug plans offered by private entities, which will provide coverage
of outpatient prescription drugs.
· The American Recovery and Reinvestment Act of
2009 provides funding for the federal government to compare the effectiveness of different treatments for the same illness.
· The Physician Payments Sunshine Act of 2010 requires
certain manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the
Children’s Health Insurance Program, with specific exceptions, to report annually to the Centers for Medicare & Medicaid Services
(“CMS”) information related to payments or other transfers of value made to physicians and teaching hospitals, and applicable
manufacturers and applicable group purchasing organizations to report annually to CMS ownership and investment interests held by the physicians
and their immediate family members.
· The Patient Protection and Affordable Care Act
of 2010 (“PPACA”) includes measures to significantly change the way healthcare is financed by both governmental and private
insurers, and significantly impacts the U.S. pharmaceutical industry. Among the provisions of the PPACA of importance to the pharmaceutical
and biotechnology industry are the following, among others: (i) extension of manufacturers’ Medicaid rebate liability to covered
drugs dispensed to individuals who are enrolled in Medicaid managed care organizations; (ii) expansion of eligibility criteria for Medicaid
programs; and (iii) expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program.
· The Budget Control Act of 2011, which, among
other things, created the Joint Select Committee on Deficit Reduction, or joint committee, to recommend proposals in spending reductions
to Congress. The joint committee did not achieve its targeted deficit reduction of at least $1.2 trillion for the years 2013 through
2021, triggering automatic reductions to several government programs. These reductions include aggregate reductions to Medicare payments
to providers of up to 2% per fiscal year, starting in 2013.
· The American Taxpayer Relief Act of 2012, reduced
Medicare payments to several providers, among other things, and increased the statute of limitations period for the government to recover
overpayments to providers from three to five years. These new laws may result in additional reductions in Medicare and other healthcare
funding.
· Depending upon the timing, duration and specifics
of the FDA approval of the use of our pharmaceutical product candidates, some of our products to be licensed under U.S. patents may be
eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred
to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments 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.
· The Biologics Price Competition and Innovation
Act (“BPCI Act”) authorizes the FDA to license a biological product that is biosimilar to an FDA-licensed biologic through
an abbreviated pathway. The BPCI Act establishes criteria for determining that a product is biosimilar to an already-licensed biologic,
or reference product, and establishes a process by which an abbreviated BLA for a biosimilar product is submitted, reviewed and approved.
40
Coverage and Reimbursement
Sales of our product candidates
in the United States may depend, in part, on the extent to which the costs of the product candidates may be covered by third-party payers,
such as government health programs, commercial insurance and managed health care organizations. These third-party payers are increasingly
challenging the prices charged for medical products and services. Additionally, the containment of health care costs has become a priority
of federal and state governments, and the prices of drugs have been a focus in this effort. The United States government, state legislatures
and foreign governments have shown significant interest in implementing cost-containment programs, including price controls, restrictions
on reimbursement and requirements for substitution of generic products. Adoption of price controls and cost-containment measures, and
adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit our net revenue and results.
If these third-party payers do not consider our product candidates to be cost-effective compared to other available therapies, they may
not cover our product candidates after approval as a benefit under their plans or, if they do, the level of payment may not be sufficient
to allow us to sell our product candidates on a profitable basis.
In order to secure coverage and
reimbursement for any product that might be approved for sale, we may need to conduct expensive pharmacoeconomic studies in order to demonstrate
the medical necessity and cost-effectiveness of the product, in addition to the costs required to obtain FDA, EMA or other comparable
regulatory approvals. Our product candidates may not be considered medically necessary or cost-effective. A payer’s decision to
provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Third-party reimbursement may
not be sufficient to enable us to maintain price levels high enough to realize an appropriate return on our investment in product development.
Pricing and reimbursement schemes
vary widely from country to country. Some countries provide that drug products may be marketed only after a reimbursement price has been
agreed. Some countries may require the completion of additional studies that compare the cost-effectiveness of a particular product candidate
to currently available therapies. The conduct of such studies could be expensive and result in delays in our commercializing efforts.
There can be no assurance that any country that has price controls or reimbursement limitations for drug products will allow favorable
reimbursement and pricing arrangements for any of our products.
The marketability of any products
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 drug pricing. Coverage policies, third-party reimbursement rates and drug pricing regulation 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.
U.S. Healthcare Reform
In the United States, there have
been and continue to be a number of significant legislative initiatives to contain healthcare costs. The PPACA contains provisions that
may reduce the profitability of drug products, including, for example, increased rebates for drugs subject to the Medicaid Drug Rebate
Program, 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.
Since its enactment, there have
been executive, judicial and Congressional challenges to certain aspects of the PPACA. On June 17, 2021, the U.S. Supreme Court dismissed
the most recent judicial challenge to the PPACA brought by several states without specifically ruling on the constitutionality of the
PPACA.
41
In addition, other legislative
changes have been proposed and adopted since PPACA was enacted. On March 11, 2021, President Biden signed the American Rescue Plan Act
of 2021 into law, which eliminates the statutory Medicaid drug rebate cap, for single source and innovator multiple source drugs, beginning
January 1, 2024. The rebate was previously capped at 100% of a drug’s average manufacturer price. Additionally, there has been
heightened governmental scrutiny in the United States of pharmaceutical pricing practices in light of the rising cost of prescription
drugs and biologics. Such scrutiny has resulted in several recent Congressional inquiries, presidential executive orders 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 products. Additional
changes included aggregate reductions to Medicare payments to providers of 2% per fiscal year, effective April 1, 2013 and, due to
subsequent legislative amendments to the statute, will stay in effect through 2027, unless additional Congressional action is taken; however,
pursuant to the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) and subsequent legislation. In January 2013,
the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, reduced Medicare payments to several providers,
and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.
These new laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect
on customers for our drugs, if approved, and, accordingly, our financial operations.
Moreover, recently there has been
heightened governmental scrutiny over the manner in which manufacturers set prices for their commercial products. There have been several
recent U.S. Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more
transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, reduce the cost of drugs under
Medicare, and reform government program reimbursement methodologies for drugs. The FDA published a final rule on October 1, 2020,
effective November 30, 2020, providing guidance for states to build and submit importation plans for drugs from Canada. Further,
on November 20, 2020, the U.S. Department of Health and Human Service (“HHS”) finalized a regulation removing safe harbor
protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy
benefit managers, unless the price reduction is required by law. The rule also creates a new safe harbor for price reductions reflected
at the point-of-sale, as well as a safe harbor for certain fixed fee arrangements between pharmacy benefit managers and manufacturers.
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.
Most recently, on August 16,
2022, the Inflation Reduction Act of 2022 (the “IRA”) was signed into law. Among other things, the IRA directs the HHS to
negotiate the price of certain high-expenditure, single-source drugs and biologics covered under Medicare. The negotiated prices, which
will first become effective in 2026, will be capped at a statutory ceiling price representing a significant discount from average prices
to wholesalers and direct purchasers. The law will also, beginning in 2023, penalize drug manufacturers that increase prices of Medicare
Part B and Part D drugs at a rate greater than the rate of inflation. Further, the IRA eliminates the “donut hole”
under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and creating
a new manufacturer discount program. The IRA permits the Secretary of the HHS to implement many of these provisions through guidance,
as opposed to regulation, for the initial years. HHS has and will continue to issue and update guidance as these programs are implemented,
although the IRA may be subject to legal challenges. It is currently unclear how the IRA will be implemented but is likely to have a significant
impact on the pharmaceutical industry. In addition, in response to the Biden administration’s October 2022 executive order,
on February 14, 2023, HHS released a report outlining three new models for testing by the Center for Medicare and Medicaid Innovation
which will be evaluated on their ability to lower the cost of drugs, promote accessibility, and improve quality of care. It is unclear
whether the models will be utilized in any health reform measures in the future.
Although a number of these and
other proposed measures may require authorization through additional legislation to become effective, Congress has indicated that it will
continue to seek new legislative measures to control drug costs.
42
CMS issued a final rule, effective
on July 9, 2019, that requires direct-to-consumer advertisements of prescription drugs and biological products, for which payment
is available through or under Medicare or Medicaid, to include in the advertisement the Wholesale Acquisition Cost, or list price, of
that drug or biological product if it is equal to or greater than $35 for a monthly supply or usual course of treatment. Prescription
drugs and biological products that are in violation of these requirements will be included on a public list.
Any adopted health reform measure
could reduce the ultimate demand for our products, if approved, or put pressure on our product pricing. Individual states in the United
States have also become increasingly active in passing legislation and implementing regulations designed to control pharmaceutical 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 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. We expect that additional state and federal
healthcare reform measures will be adopted in the future.
We expect that additional state
and federal healthcare reform measures, as well as legal changes by foreign governments, will be adopted in the future, any of which could
limit the amounts that governments will pay for healthcare products and services, which could result in reduced demand for our product
candidates or additional pricing pressures.
Employees and Human Capital Resources
As of December 31, 2024,
we had 10 full-time employees plus a number of contract workers, who manage and oversee all aspects of our operations, including nonclinical
development, manufacturing, clinical development, and general and administrative functions. Seven employees were engaged in research and
development activities. In addition, we currently work with numerous highly experienced consultants and contractors who provide management
and oversight in manufacturing, analytical, clinical supply chain, regulatory, pharmacovigilance and safety, clinical operations, data
management, statistics, non-clinical toxicology, nonclinical and clinical pharmacology, and medical affairs. Thus, we currently operate
as a semi-virtual pharmaceutical company with expertise in numerous aspects of preclinical and clinical development. Many of our consultants
and contractors have extensive experience specifically in the development of cancer drugs.
None of our employees are represented
by a labor union or covered under a collective bargaining agreement. We consider our relationship with our employees to be good.
