PART I
Item 1. Business.
Overview
We are a clinical-stage
biopharmaceutical company focused on the development of therapeutics for the treatment or prevention of addiction and related disorders.
Our investigational new drug candidate, AD04, is being developed as a therapeutic agent for the treatment of alcohol use disorder (“AUD”).
AD04 was recently investigated in a Phase 3 clinical trial, designated the ONWARD trial, for the potential treatment of AUD in subjects
with certain target genotypes, which were identified using our companion diagnostic genetic test. Based on our analysis of the subgroup
data from the ONWARD trial, we are now focused on completing the clinical development program for AD04 in the specified genetic subgroups
to meet regulatory requirements primarily in the US and secondarily in Europe/UK.
In January 2021, we expanded
our portfolio in the field of addiction with the acquisition of Purnovate, LLC via a merger into our wholly owned subsidiary, Purnovate,
Inc. (“Purnovate”) and in January 2023, we entered into an option agreement with Adovate LLC (“Adovate”), pursuant
to which we granted to Adovate an exclusive option for Adovate or its designated affiliate to acquire all of the assets of Purnovate and
to assume related liabilities and expenses. (Our then-CEO was a significant equity holder in Purnovate, LLC, so this was considered a
related party transaction.) On May 8, 2023, Adovate sent a letter exercising its option effective May 16, 2023 and made payment of the
$450,000 in fees due on exercise. Effective June 30, 2023, Adovate issued to us the equity stake in Adovate due on exercise of the option
agreement. On August 17, 2023, a Bill of Sale, Assignment and Assumption Agreement (“Bill of Sale”) was executed between Purnovate
and Adovate, transferring the Purnovate assets to Adovate, effective as of June 30, 2023. On August 17, 2023, Purnovate and Adovate also
entered into a letter agreement acknowledging that Adovate acquired the assets of Purnovate effective as of June 30, 2023, pursuant to
the Bill of Sale.
We have devoted the vast
majority of our resources to development efforts relating to AD04, including preparation for and conducting clinical trials, providing
general and administrative support for these operations and protecting our intellectual property. We expect these activities to continue
to demand most of our resources for the foreseeable future.
We currently do not have
any products approved for sale and we have not generated any significant revenue since our inception. From our inception through the date
of this Annual Report on Form 10-K, we have funded our operations primarily through the private and public placements of debt, equity
securities, and an equity line.
Our current cash and
cash equivalents are not expected to be sufficient to fund operations for the twelve months from the date of filing this Annual Report
on Form 10-K, based on our current commitments and development plans.
We have incurred net
losses in each year since our inception, including net losses of approximately $13.2 million and $5.1 million for the years ended December
31, 2024 and 2023, respectively. We had accumulated deficits of approximately $82.0 million and $68.8 million as of December 31, 2024
and 2023, respectively. All of our operating losses in the year ended December 31, 2024 resulted from costs incurred in continuing operations,
including costs in connection with our continuing research and development programs and from general and administrative costs associated
with our operations. Our net loss for the year ended December 31, 2024 also includes uncapitalized financing costs, such as the cost of
issuing new warrants to induce a holder to exercise existing warrants and the cost of inducement shares.
We will not generate
revenue from product sales unless and until we successfully complete development and obtain marketing approval for AD04, which we expect
will take a number of years and is subject to significant uncertainty. We do not believe our current cash and equivalents will be sufficient
to fund our operations for the next twelve months from the date of the accompanying financial statements.
Until such time, if ever,
as we can generate substantial revenue from product sales, we expect to finance our operating activities through a combination of equity
offerings, debt financings, government or other third-party funding, commercialization, marketing and distribution arrangements and other
collaborations, strategic alliances and licensing arrangements. However, we may be unable to raise additional funds or enter into such
other arrangements when needed on favorable terms or at all. Our failure to raise capital or enter into such other arrangements as and
when needed would have a negative impact on our financial condition and our ability to develop AD04.

Recent Developments
Purchase Agreement
On December 13,
2024, we entered into a Purchase Agreement (the “Purchase Agreement”) with Alumni Capital LP (“Alumni Capital”).
Pursuant to the Purchase Agreement, we have the right to sell to Alumni Capital up to the lesser of (i) $5,000,000 of newly issued shares,
subject to increase to $10,000,000 at our option (the “Investment Amount”), of the shares (the “Shares”) of the
Company’s common stock, par value $0.001 per share (the “Common Stock”), and (ii) the Exchange Cap (as defined below)
(subject to certain conditions and limitations), from time to time during the term of the Purchase Agreement. Sales of Common Stock pursuant
to the Purchase Agreement, and the timing of any sales, are solely at our option and we are under no obligation to sell securities pursuant
to this arrangement. Shares of Common Stock may be sold by us pursuant to this arrangement over a period ending on the earlier of December
31, 2026 or the date on which Alumni Capital shall have purchased Shares pursuant to the Purchase Agreement for an aggregate purchase
price of the Investment Amount; provided, however that we can terminate the Agreement at any time upon ten days prior written notice, subject
to the satisfaction of the conditions in the Purchase Agreement.
Upon the satisfaction
of the conditions in the Purchase Agreement, including that a registration statement that we agreed to file with the Securities and Exchange
Commission (the “SEC”) pursuant to the Purchase Agreement is declared effective by the SEC and a final prospectus in connection
therewith is filed with the SEC, we will have the right, but not the obligation, from time to time at our sole discretion over the period
described above, to direct Alumni Capital to purchase up to a fixed maximum amount of shares of Common Stock as set forth in the Purchase
Agreement; provided, that Alumni Capital’s maximum commitment under any single fixed purchase will not exceed the greater of (i) $500,000
and (ii) 150% of the average daily trading volume of the Common Stock during the five (5) days immediately prior to the date that
we deliver a Purchase Notice, without mutual agreement of Alumni Capital; further provided, however, that the maximum commitment under
any single fixed purchase will in no case exceed $1,250,000 or, with mutual agreement of Alumni Capital, $2,500,000.
The purchase price per
Share that may be sold to Alumni Capital under the Purchase Agreement in such fixed purchases equals ninety-seven percent (97%) of the
lowest daily dollar volume-weighted average price for the Common Stock during the period ending on the earlier of (i) three (3) consecutive
trading days period following the date we deliver a purchase notice and (ii) the date on which Alumni Capital notifies us that it is prepared
to proceed with the closing, subject to a Minimum Acceptable Price (as defined in the Purchase Agreement). There is no upper limit on
the price per share that Alumni Capital might be obligated to pay for the Common Stock under the Purchase Agreement; provided, however,
that at no time can the purchase price be below $0.55 per share (subject to adjustment as provided in the Purchase Agreement for any reorganization,
recapitalization, non-cash dividend, stock split, or other similar transaction occurring after the date of the Purchase Agreement).
We will control the timing
and amount of any sales of Shares to Alumni Capital. Actual sales of Shares to Alumni Capital under the Purchase Agreement will depend
on a variety of factors to be determined by us from time to time, including, among other things, market conditions, the trading price
of the Common Stock and determinations by us as to the appropriate sources of funding for us and our operations.
Under the applicable
rules of the Nasdaq Stock Market LLC (“Nasdaq”), in no event may we issue more than 1,280,515 Shares (including the Commitment
Shares, as defined below), representing 19.99% of the shares of the Common Stock outstanding immediately prior to the execution of the
Purchase Agreement (the “Exchange Cap”), to Alumni Capital under the Purchase Agreement, unless we obtain stockholder approval
to issue shares of Common Stock in excess of the Exchange Cap, provided further that the Exchange Cap does not apply to the extent the
purchase price is equal to or exceeds the Minimum Price, which is $1.09. If stockholder approval to exceed the Exchange Cap were obtained
and all $5,000,000 were to be sold at $0.55 per share, we would issue a total of 9,090,909 shares of Common Stock (not including the Commitment
Shares).
2
In all instances, we
may not sell shares of our Common Stock to Alumni Capital under the Purchase Agreement if it would result in Alumni Capital beneficially
owning more than 4.99% of the Common Stock.
As consideration for
Alumni Capital’s irrevocable commitment to purchase Shares upon the terms of and subject to satisfaction of the conditions set forth
in the Purchase Agreement, concurrently with the execution and delivery of the Purchase Agreement, we issued to Alumni Capital 68,807 shares
of Common Stock (the “Commitment Shares”). If we were to elect to increase the number of the shares of Common Stock available
for purchase under the Purchase Agreement from $5,000,000 up to a limit of $10,000,000, we would be obligated to issue to Alumni Capital
additional shares of Common Stock as a commitment fee equal to 1.5% of the increased amount divided by the closing price of the Common
Stock on the date of issuance and delivery by us of the notice to increase such amount.
Pursuant to the Purchase
Agreement, we have agreed to file a registration statement with the SEC to register for resale under the Securities Act of 1933, as amended
(the “Securities Act”) the shares of our Common Stock that may be issued to Alumni Capital under the Purchase Agreement, including
the Commitment Shares. The registration statement was declared effective on December 30, 2024. The Purchase Agreement contains customary
representations, warranties, conditions and indemnification obligations of the parties. The representations, warranties and covenants
contained in such agreements were made only for purposes of such agreements and as of specific dates, were solely for the benefit of the
parties to such agreements and may be subject to limitations agreed upon by the contracting parties.
Pharmacokinetics Study
On November 14, 2024,
we issued a press release announcing that we completed a pharmacokinetics (PK) study of AD04. The study, a single-center, relative bioavailability,
open label study, enrolled a total of 30 healthy adult volunteers in two cohorts. Cohort 1 (n=6) was a randomized, open-label, 2-sequence,
2-period crossover study to evaluate the PK variability of ondansetron from AD04 0.33 and 0.99mg. Cohort 2 (n=24) was a randomized, open-label,
6-sequence, 4-period crossover study to evaluate the relative bioavailability of the AD04 0.33mg tablet to a marketed ondansetron 4mg
tablet, dose proportionality of ondansetron PK between AD04 0.33 and 0.99mg, and the effect of food on the bioavailability of ondansetron
administered as the AD04 0.33mg tablet. The results of this study showed that, as a result of the lower dose, AD04 0.33mg delivered lower
ondansetron PK exposure than the marketed reference standard ondansetron 4mg tablet; ondansetron pharmacokinetic exposure increased in
proportion to dose across a 3-fold AD04 dose range; and AD04 can be taken in fed or fasted states. This data is expected to help us optimize
study design elements needed for the upcoming Phase 3 clinical trial of AD04. Completion of this study also satisfied an FDA requirement
for the upcoming Phase 3 clinical trials of AD04.
Chief Financial Officer
On November 1, 2024,
we entered into a Separation Agreement and Release, dated November 1, 2024 (the “Separation Agreement”), with Joseph Truluck,
our former Chief Financial Officer. Pursuant to the Separation Agreement, Mr. Truluck will receive: (i) from November 1, 2024 through
December 31, 2024, 100% of his current base salary during which period he would serve until November 15, 2024 as our Chief Financial Officer
and thereafter as a consultant to us, (ii) from January 1, 2025 through March 31, 2025, 50% of his current base salary as a consultant
to us, and (iii) from and after March 31, 2025, $350 an hour as a consultant to us on an as needed basis.
On November 1, 2024, our board of directors
appointed Vinay Shah as our Chief Financial Officer, effective November 16, 2024. In connection with his appointment, we entered into
an employment agreement with Mr. Shah (the “Shah Employment Agreement”) to employ Mr. Shah as our Chief Financial Officer
for a three-year term effective November 16, 2024 at an annual base salary of $315,000, with a discretionary bonus of up to 30% of his
base salary upon achievement of objectives as may be determined by our board of directors. The Shah Employment Agreement provides for
six (6) months’ severance for a without cause termination of employment and twelve (12) months’ severance for a without cause
termination of employment following a change of control of the Company. Pursuant to the Shah Employment Agreement, we issued a Mr. Shah
a stock option to purchase up to 40,000 shares of common stock pursuant to our 2017 Equity Incentive Plan (the “Plan”), which
vests pro rata on a monthly basis over 36 months, at an exercise price of $1.06.
3
At-the-market Offering Agreement
On April 18, 2024, we entered into an At the Market
Offering Agreement (the “ATM Agreement”) with H.C. Wainwright & Co., LLC (the “Sales Agent” or “Wainwright”)
providing for sale of our shares of common stock, from time to time, through the Sales Agent, with certain limitations on the number of
shares of common stock that may be offered and sold by us as set forth in the ATM Agreement. The aggregate market value of the shares
of Common Stock eligible for sale under the ATM prospectus supplement filed in connection with the ATM Agreement was $4,283,650 which
is based on the limitations of such offerings under SEC regulations. The ATM Agreement provides that we will pay the Sales Agent commissions
for its services in acting as agent in the sale of shares of common stock pursuant to the ATM Agreement. The Sales Agent will be entitled
to compensation at a fixed commission rate of 3.0% of the gross proceeds from the sale of shares of common stock pursuant to the ATM Agreement.
The offering of shares of common stock pursuant to the ATM Agreement will terminate upon the earlier of (i) the sale of all shares of
common stock subject to the ATM Agreement; or (ii) termination of the ATM Agreement by us as permitted therein. During the year ended
December 31, 2024, we sold 2,348,520 shares of common stock under the ATM Agreement for net proceeds of approximately $4.0 million.
AD04 Clinical Development Program
Adial’s AD04 clinical development program
began with initiation of a Phase 3 trial, otherwise known as the ONWARDTM trial. Adial believed that the ONWARD trial design provided
the flexibility to meet global regulatory requirements. The trial started in February 2020 in Scandinavia and Central and Eastern Europe.
The ONWARD trial was a 24-week, multicenter, randomized, double-blind, placebo-controlled, parallel group, Phase 3 clinical study to evaluate
the efficacy, safety and tolerability of AD04 in patients with AUD and selected polymorphisms in the serotonin transporter and receptor
genes. Patients were genetically screened prior to enrollment in the ONWARD trial so that only genetically positive patients were enrolled.
ONWARD enrolled 302 patients (a total of 303 patients were recruited and then randomized in the trial, however, one subject never initiated
treatment and has been excluded from enrollment numbers and was not included in the full analysis data set or efficacy analysis for the
trial); and was conducted in 25 clinical sites in six countries in Scandinavia and Central and Eastern Europe (Sweden, Finland, Poland,
Latvia, Bulgaria and Croatia). Approximately one-third of the total screened patients tested positive for the targeted genotypes.
A Phase 2b study (N = 283), conducted by the University
of Virginia for which we have acquired rights to the data, showed that a prospectively identified subgroup of alcohol-dependent individuals
with specific polymorphisms of the serotonin transporter protein responded therapeutically to ondansetron administration (Johnson, BA
et al., 2011). Further analysis of this same data set against 18 additional polymorphisms located on the genes for the A and B subunits
of the serotonin 5-HT3 receptor revealed polymorphisms that were also associated with a therapeutic response to ondansetron. It was this
hypothesis that collectively led Adial to focus the ONWARD trial on genotypes LL/TT, GG, AG, and AC.
The primary efficacy endpoint of the ONWARD trial
was the average percentage change from baseline in the monthly heavy drinking days (PHDD) experienced by each patient in months 5 and
6 combined. Key secondary endpoints included reduction in total alcohol consumed (TAC), and improvement as measured by the Patient Health
Questionnaire-9, a widely accepted tool for assessment of depression. The definition of a heavy drinking day was greater than 40 grams
or 60 grams of ethyl alcohol in a day for a woman or a man, respectively.
ONWARD Phase 3 Clinical Trial Results – Topline Data Analysis
Topline Data Analysis
On July 20, 2022, we announced the following results
from the ONWARDTM Phase 3 trial. Although the trial missed the primary endpoint, it did show statistical significance in a pre-defined
patient group.
Heavy drinkers are defined by NIAAA (National
Institute on Alcohol Abuse and Alcoholism) as men who drink 5 or more drinks on any day or 15 or more per week and women who drink 4 or
more drinks on any day or 8 or more per week. AD04 patients, compared with placebo patients, achieved a statistically significant reduction
from baseline at month six in percentage of heavy drinking days (PHDD) for the pre-specified patient group of heavy drinkers, across all
genotypes combined (avg. <10 drinks per drinking day at baseline; p=0.03), which accounted for approximately two-thirds of the trial
population. A similar trend was seen in the combined month five and six analysis in the reduction from baseline (p =0.07). Notably, in
the last month of the trial, AD04 heavy drinking patients had a mean reduction of approximately 79% in heavy drinking compared with baseline.
4
Compared with placebo patients, AD04 patients
in the heavy drinking group had an overall significant difference in the severity of their AUD diagnosis (p=0.04) under the Diagnostic
and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). For the group of those who no longer meet AUD criteria (<2 symptoms),
the comparisons were 27.4% vs. 14.9% (i.e., an 84% decrease), of AD04 and placebo patients, respectively. These data underscore the clinical
relevance of the findings that heavy drinking AUD patients that receive AD04 appear more likely to recover from the disease by the end
of the treatment regimen.
Additionally, and consistent with the Phase 2b
trial, AD04 had a safety and tolerability profile that was similar to placebo. No side effects or severe adverse events (SAEs) were determined
to be related to AD04 treatment. In fact, more SAEs were reported in the placebo group compared with the AD04 group (7 on placebo vs.
3 on AD04). There were two cardiac events in placebo group and none in the AD04 group. Comparing overall Adverse Events (AEs), the profiles
between AD04 and placebo were similar. AEs reported with a frequency of 5% or more of patients in either group were: headache (11% on
placebo, 12% on AD04), insomnia (3% on placebo, 7% on AD04), blood magnesium decreased (5% on placebo, 6% on AD04), and fatigue (3% on
placebo, 6% on AD04). All of the AE’s were reported as mild to moderate. Importantly, in the overall category of cardiac disorders,
patients on placebo showed a greater number of adverse events compared to AD04 (7% on placebo, 4% on AD04), in addition to greater number
of cardiac SAEs in the placebo group as reported above.
US Clinical Development and Regulatory Actions
Completed
Utilizing both the Phase 2 and ONWARD <10 DDD
(Drinks per Drinking Day) Responder Analysis datasets, additional post-hoc analysis was conducted using the FDA specified endpoint of
reduction of heavy drinking days (PNHDD), defined as the percentage of patients that have zero heavy drinking days during the efficacy
observation period of months 5 and 6, for AD04 vs placebo compared to baseline at study entry. (FDA Feb. 2015 Draft Guidance Alcoholism:
Developing Drugs for Treatment Guidance for Industry) and which the FDA in prior meetings has indicated will be acceptable. When applying
a PNHDD endpoint during the post hoc Phase 2 data analysis, the genotype polymorphism AG+ showed a statistically significant difference
at month 3 compared to placebo (p=0.031). Equally, the post hoc analysis of the PNHDD endpoint of the ONWARD data set the AG+ polymorphism
also demonstrated a statistically significant difference at month’s 5&6 compared to placebo (p= 0.021). This important post
hoc analysis brings a new clinical development focus for future trials of AD04 in the heavy drinking AUD population. Additionally, while
the GG+ polymorphism did not achieve statistical significance in this analysis, the GG+ polymorphism showed promising trends toward achieving
the PNHDD endpoint and we believe that the GG+ polymorphism may be important for future trials. There was a substantial difference between
the treatment and placebo arms in the percentage of patients that achieved zero heavy drinking days within the AG and GG polymorphism
groups. In the same post hoc analysis comparing genotype polymorphisms in both the Phase 2 and Phase 3 against PNHDD for LL/TT no statistically
significant difference was seen.
When analyzing the Phase 3 Study ONWARD, DDD <10,
Responder Analysis Results at Months 5 and 6, we also examined the important measure of treatment effect. Treatment effect is a measure
of clinical meaningfulness. Treatment effect is defined in both absolute reduction of heavy drinking days as well as percentage change
of no heavy drinking days in AD04 vs placebo. In the AG+ group the AD04 treatment group achieved 49% of days with no heavy drinking vs
22% with placebo, or a 1.23 times better reduction of heavy drinking days vs placebo. The GG+ group achieved a 25% change in no heavy
drinking days vs 7% in the placebo group, or a 2.53 times better reduction of heavy drinking days vs placebo. When the same analysis was
conducted with the LL/TT genotypes no difference was found, further supporting the future direction and focus on the AG+ and GG+ genotypes.
These analyses are the basis of our future direction
of clinical, regulatory and commercial strategy in the United States.
Our regulatory strategy for the US has been clearly
defined as a result of both ongoing discussions with key advisors in US regulatory affairs as well as face to face meetings with the FDA.
In April 2023, we met with the FDA Division of Anesthesiology, Addiction and Pain Medicine (DAAP), the division responsible for reviewing
the NDA submission for AD04 if submitted in the future. The primary objective of this meeting with the FDA was to seek clarity on the
path forward based on the Phase 2 results, Phase 3 results, and post-hoc analysis of the Phase 2 and Phase 3 data.
5
In July 2023, we announced a summary of feedback
received during the meeting. The FDA acknowledged and confirmed the importance of ongoing research in the AUD therapeutic area as a persistent
high unmet need. We received (1) confirmation of the primary US endpoint based on Percentage of No Heavy Drinking Days (“PNHDD”),
which utilized a responder analysis of patients who reduced their alcohol consumption to zero heavy drinking days in the last 2 months
of a 6-month study, (2) acknowledgment of results from the Phase 2 and Phase 3 post hoc analysis against PNHDD, which demonstrated statistical
significance of responder analysis of specific genotypes as useful information for planning future studies of AD04, (3) acknowledgement
that the safety data from the ONWARD trial did not raise any concerns, (4) confirmation of the importance of identifying a patient subgroup
where a relevant treatment effect and compelling evidence of a favorable risk-benefit profile can be assessed (5) acknowledgment that
the post hoc analysis shows positive progress and potentially promising clinically meaningful effect in specific genetic subtypes, and
(6) a request for additional data to support an NDA and approval for AD04.
Based on this positive feedback received from
the FDA, we have made the strategic decision to focus our efforts on the US, with the understanding that the US standards may translate
to acceptance in other international markets.
US Clinical Development and Regulatory Actions
Planned
We have assessed the impact of the regulatory
guidance on the future business and operating plan requirements to meet the needs of the FDA for submission and approval of AD04 to treat
genetic subtypes of AUD. While we are in the process of confirming the impact on the clinical development plans and timing with our external
advisors and ongoing partnership discussions, the following provides a working summary of the planned strategy, which is subject to final
discussions with the regulatory agencies.
Regulatory feedback indicates that even though
a single additional Phase 3 trial with convincing data may suffice for approval, it would be a review issue for the agencies following
trial completion to determine if the data was sufficient for approval. Therefore, while possible to file for registration with one additional
trial, current planning assumptions are that we will need to conduct two Phase 3 trials with AD04, ideally in parallel. The second trial
will likely include a biomarker negative patient arm to satisfy any ongoing questions from the regulators regarding efficacy parameters.
This is expected to support potential approval in the shortest time frame and removes future regulatory filing and review risk that would
be associated with conducting a single additional trial. Confirmation of the clinical development plan and pathway is currently being
conducted by our clinical development and regulatory advisors. In addition to the Phase 3 studies described above, several smaller additional
studies required by the FDA may be conducted including bioavailability studies and longer-term safety data on at least 100 AD04 treated
patients from the Phase 3 (per ICH E1A guidance).
Based on the new expectations regarding the targeted
genotypes, the two additional Phase 3 trials are currently expected to require $8-12 million each in direct expenses, and up to $5 million
in additional other development expenses. These estimates may change based on upcoming discussions with regulatory authorities and final
trial designs.
EX US Clinical Development and Regulatory
Actions Completed
As previously referenced, the primary efficacy
endpoint of the ONWARD trial was the average percentage change from baseline in the monthly heavy drinking days (PHDD) experienced by
each patient in months 5 and 6 combined. Key secondary endpoints included reduction in total alcohol consumed (TAC) and improvement as
measured by the Patient Health Questionnaire-9, a widely accepted tool for assessment of depression. The definition of a heavy drinking
day was greater than 40 grams or 60 grams of ethyl alcohol in a day for a woman or a man, respectively.
In the major EU4 countries, the primary regulatory
authority is the EMA (European Medicines Agency). Current draft guidelines released by the EMA, CHMP (Committee for Medicinal Products
for Human Use), 2010, are the basis of clinical development planning in the EU4 and, the MHRA (Medicines and Healthcare Products Regulatory
Agency), in the UK. These agencies differ from the FDA in their views of clinical endpoints, and therefore future clinical development
and regulatory strategies should account for these differences. The primary differences are that EU and UK regulators consider the change
in HDD (heavy drinking days) and TAC (total alcohol consumed in grams) at month 6, the efficacy observation period vs the FDA which considers
the PNHDD (percentage of no heavy drinking days) at months 5 and 6 as the efficacy observation period. There are also differences in the
total grams of alcohol which constitute a standard drink in the EMA vs US (10 to 14 grams in Europe versus 14 grams in the United States),
and therefore the definitions of the number of drinks which constitute a heavy drinking day are also slightly different.
6
According to the EMA CHMP guidance, any study
drug for alcohol dependence that is not focused to achieve abstinence should be addressing the intermediate goal of clinically significant
moderation. Efficacy should be expressed by change to baseline in total consumption of alcohol (TAC, presented as amount of pure alcohol
in grams per day) as well as by reduction in number of Heavy Drinking Days (HDD defined as more than 60 grams of pure alcohol in men and
40 grams in women). Both are considered primary variables, since HDD are associated with specific risks such as acute cardiovascular outcomes
or accidents. A clinically relevant difference compared to placebo should be demonstrated. Further, efficacy on these two variables should
be reflected in a clearly expectable improved health outcome on an individual patient level. Therefore, efficacy should also be evaluated
in terms of responders. This could be done by evaluating the proportion of subjects with a 50%, 70% and 90% reduction in alcohol consumption
as well as the proportion of patients achieving maintained abstinence. Another option would be evaluating the proportion of subjects with
a significant categorical shift in WHO (World Health Organization) risk levels of drinking (i.e. proportion of patients with change of
consumption to baseline from very high risk to at least medium risk level and change from high risk to at least low risk level, as well
as the proportion of patients with full abstinence. In general, the harm reduction of populations through the reduction of alcohol consumption
is recognized by EMA and MHRA and has been used for prior drug product approvals in the EU with a focus on reducing HDD as well as TAC.
Examining the endpoints outlined in guidance from
EMA/CHMP, we completed a post hoc analysis of the ONWARD trial. AD04 patients, compared with placebo patients, showed a trend in the reduction
from baseline at month six in heavy drinking days for the combined trial population of heavy and very heavy drinkers (p=NS). A similar,
non-statistically significant trend was seen in the combined months five and six analysis in the average percentage change of heavy drinking
days (PHDD) from baseline, which was the pre-specified primary efficacy analysis.
Also, in July 2023, we announced results from
meetings held with key country-level regulatory agencies in Europe. The results of these meetings as previously reported are being used
for the development of our future clinical and regulatory strategy.
EX US Clinical Development and Regulatory
Actions Planned
As previously stated, based on positive feedback
received from the relevant global regulatory bodies and overlapping clinical requirements, we made the strategic decision to focus our
efforts on the US. We believe that these clinical endpoints should translate to acceptance in other international markets. We will continue
to look for synergies where they exist in the primary efficacy data variables when planning for study designs to meet global regulatory
requirements. We have a high level of confidence in the US clinical program based on our post hoc analysis and regulatory feedback and
we believe these data results to be useful for Ex US regulators.
However, if these synergies cannot be found, it
is possible that new analysis and/or additional data generation may be required to meet the requirements of global regulators, including
the EU and UK. This is also vital for our ongoing partnering efforts based on discussions with companies active in the EU and UK.
Disease Overview - Alcohol Use Disorder
AUD is characterized by an urge to consume alcohol
and an inability to control the levels of consumption.
The 2022 National Survey on Drug Use and Health
(NSDUH), commissioned by The Substance Abuse and Mental Health Services Administration (SAMHSA), reported the percentage of heavy alcohol
use highest among young adults age 18-25 (7.6% or 2.6 M people) followed by adults age 26 and over (6% or 13.4M people). In the United
States, 29.5 million people age 12 and older had AUD, according to the 2022 National Survey on Drug Use and Health (NSDUH). AUD results
in significant health, social, and financial costs, with excessive alcohol use being the third leading cause of preventable death and
responsible for 31% of driving fatalities (NIAAA Alcohol Facts & Statistics). AUD contributes to over 200 different diseases and 10%
of children live with a person that has an alcohol problem. According to the American Society of Clinical Oncologists, 5-6% of new cancers
and cancer deaths globally are directly attributable to alcohol. And, The Lancet published an article that alcohol is the leading
risk factor for death and disability in people ages 15-49 globally. The Centers for Disease Control (the “CDC”) has reported
that AUD costs the U.S. economy about $250 billion annually, with heavy drinking accounting for greater than 75% of the social and health
related costs.
AUD is characterized by an urge to consume alcohol
and an inability to control the levels of consumption. Until the publication of the fifth revision of the Diagnostic and Statistical Manual
of Mental Disorders in 2013 (the “DSM-5”), AUD was broken into “alcohol dependence” and “alcohol abuse”.
More broadly, overdrinking due to the inability to moderate drinking is called alcohol addiction and is often called “alcoholism”,
sometimes pejoratively.

Limitations of Current AUD Therapies
Today the most common treatments for AUD are directed
at achieving abstinence and typical treatments include psychological and social interventions. Most therapies actually require abstinence
prior to initiating therapy. Abstinence requires dramatic lifestyle changes often with serious work and social consequences. Frequently,
patients cannot attend family and social events in order to ensure compliance with abstinence, and patients often must suffer from the
stigma of having been labelled an alcoholic. Significant side effects of current pharmacologic therapies include mental side effects such
as psychiatric disorders and depressive symptoms and physical side effects such as nausea, dizziness, vomiting, abdominal pain, and hepatoxicity.
In fact, according to peer reviewed studies referenced in The Sober Truth: Debunking the Bad Science Behind 12-Step Programs and the
Rehab Industry, L. Dodes and Z. Dodes, 2014 by Dr. Lance Dodes, the former Director of the substance abuse treatment unit of Harvard’s
McLean Hospital, 90% or more of patients that use current therapy solutions, such as Alcoholics Anonymous, do not achieve long-term abstinence.
There are four drugs approved by the FDA and marketed
in the United States for the treatment of alcohol addiction, Antabuse® (disulfram) Vivitrol® (naltrexone),
Revia® (naltrexone) and Campral® (acomprosate) and one drug, Selincro® (nalmefene) is marketed
outside of the United States. All of the approved drugs, other than Selincro®, require abstinence prior to commencing treatment
with the drug, and all five drugs are known to have significant side effects.
Antabuse® was approved for the
treatment of alcohol dependence more than 50 years ago, making it the oldest such drug on the market. It works by interfering with the
body’s ability to process alcohol. Its method of action and purpose is to cause patients that drink alcohol while taking Antabuse®
to experience numerous and extremely unpleasant adverse effects, including, among others, flushing, nausea, and palpitations, with the
goal that patients will continue the medication but refrain from drinking in order to avoid these effects.
Naltrexone, which can be taken as a once-daily
pill (Revia®) or in an approved once-monthly injectable form (Vivitrol®) that requires a doctor to administer
is often associated with gastrointestinal complaints and has been reported to cause liver damage when given at certain high doses. As
a result, it carries an FDA boxed warning, a special emphasized warning, for this side effect. Vivitrol is currently being marketed by
Alkermes to physicians for the treatment of AUD.
Campral®, taken by mouth three
times daily, acts on chemical messenger systems in the brain.
Selincro® has not been approved
for sale in the United States.
Our Proposed Solution is AD04 and a PGx Companion
Diagnostic
The active pharmaceutical agent in AD04, our lead
investigational new drug product, is ondansetron, which is also the active ingredient in Zofran®, which was granted FDA
approval in 1991 for nausea and vomiting post-operatively and after chemotherapy or radiation treatment and is now commercially available
in generic form. In studies of Zofran®, conducted as part of its FDA review process, ondansetron was given acutely at dosages
up to almost 100 times the dosage expected to be formulated in AD04 with the highest doses of Zofran® given intravenously
(“i.v.”), which results in approximately 160% of the exposure level as oral dosing. Even at high doses given i.v. the studies
found that ondansetron is well-tolerated and results in few adverse side effects at the currently marketed doses, which reach more than
80 times the AD04 dose and are given i.v. The formulation dosage of ondansetron used in our drug candidate (and expected to be used by
us in our Phase 3 clinical trials) has the potential advantage that it contains a much lower concentration of ondansetron than the generic
formulation/dosage that has been used in prior clinical trials, is dosed orally, and is available with use of a companion diagnostic genetic
biomarker. Our development plan for AD04 is designed to demonstrate both the efficacy of AD04 in the genetically targeted population and
the safety of ondansetron when administered chronically at the AD04 dosage. However, to the best of our knowledge, no comprehensive clinical
study has been performed to date that has evaluated the safety profile of ondansetron at any dosage for long-term use as anticipated in
our ongoing and planned clinical trials. Under current US FDA regulations, the approval of the specific dosage of 0.33mg ondansetron in
AD04 for the new indication of AUD in patients with genetic subtypes and data exclusivity will result in a minimum of 3 years of regulatory
and, therefore, commercial exclusivity for AD04 in the US.
8
Our goal with AD04 is to develop an effective
and safe product to treat AUD that does not require abstinence as part of the treatment and does not have the negative side effects of
the current drugs on the market. Our product candidate, AD04, is designed for genotype positive patients who desire to control their drinking
but cannot or do not want to completely abstain from drinking. By removing the difficulties associated with abstinence and the side effects
associated with the other current products on the market, we believe that we may be able to remove barriers to patient adoption that inhibit
adoption of current therapies and can attract a greater portion of the many millions of patients with AUD that remain untreated. Unlike
other therapies, our investigational product, AD04, uses a novel mode of action for treating AUD that involves genetic screening with
a companion diagnostic genetic test prior to treatment and is designed to reduce cravings for alcohol to effectively curb alcohol intake,
without the requirement of abstinence prior to or during treatment. Our product candidate is intended to be easy to use since it is administered
orally, currently on a twice daily basis and with a once-a-day tablet planned as part of the product’s life cycle management. To
date, clinical testing of AD04 has shown it to have a positive safety and tolerability profile with side effects similar to placebo.
The companion diagnostic genetic test to be used
to identify patients that are most likely to benefit from treatment with AD04 may potentially enhance the likelihood of a successful outcome
for those undergoing treatment. Additionally, it may provide doctors with the opportunity to have a non-threatening conversation about
alcohol with their patients and may provide the patient an acceptable path to help them determine if they might be a candidate for help
with their alcohol use. If the test results are positive, they would have a science-based rationale for their treatment, which reduces
some of the stigma patients might otherwise endure, and potentially allows them to be treated in the confidence of their doctor with an
oral tablet.
Strengths and Competitive Advantages
Large Market Opportunity for an Effective
Solution
In the United States
alone, the 2021 National Survey on Drug Use and Health (NSDUH) reported approximately 30 million people age 12 and older had AUD. Of those,
only 2.6 million people received treatment at any healthcare location, and of those who received treatment at any healthcare location,
only 0.9% (265,000) received medication assisted treatment (MAT). Based on data from the ONWARD trial and Phase 2b trial of AD04 and our
analysis of publicly available genetic databases, we preliminarily estimate that about one in three patients with AUD in the U.S. and
Europe will have the genetic markers to indicate possible treatment with AD04. Our initial focus, based on the subgroup analysis will
include genotypes, AG and possibly GG, that we estimate represent about 14% and 6% of AUD patients in the U.S, and Europe, respectively
and 20% collectively. At this time, we are not aware of any oral pharmaceutical treatment approved in the U.S. that addresses the needs
of patients who desire to control their drinking but cannot or do not want to abstain from drinking. The current abstinence-based treatments
have limitations, as outlined in the previous section “Limitations of Current AUD Therapies”. The limited side effects expected
for our investigational new drug, based on clinical data so far, are also believed to be an important factor in the expected rapid uptake
of AD04 in the market. Our approach, if approved by FDA, may allow for social drinking to continue and is aimed at reducing the dangerous,
heavy drinking. This would allow patients to live the life they want without the stigma associated with complete abstention and currently
endured by those seeking help for their excessive drinking.
According to the WHO (World Health Organization,
2022), the harmful use of alcohol is a causal factor in more than 200 disease and injury conditions. Worldwide, 3 million deaths every
year result from harmful use of alcohol. This represents 5.3% of all deaths. Overall, 5.1% of the global burden of disease and injury
is attributable to alcohol, as measured in disability-adjusted life years (DALY’s). Alcohol consumption causes death and disability
relatively early in life. In people aged 20-39 years, approximately 13.5% of total deaths are attributable to alcohol.
Companion Genetic Bio-Marker Test Aimed
at Identifying Patients Most Likely to Respond To Treatment, Potentially Results in Increased Use of AD04
We believe our AD04 and its companion diagnostic
is unique in that it is designed to reduce heavy drinking in individuals with certain genotypes. We are pursuing a strategy that aims
to integrate pre-treatment screening with the companion diagnostic genetic test into the drug label, essentially combining the test and
treatment into one integrated therapeutic. This companion diagnostic testing approach may be a useful genetic screening tool to predict
those most likely to respond to the drug and to have minimal side effects. Based on the clinical experience to date and publicly available
databases, we believe the genetic prevalence of genotype positive people is about 33% of the population in the United States and Europe.
9
We believe that the companion diagnostic genetic
test enables physicians to more easily have an initial conversation with their patients about alcohol use and, for the patient, provides
a less threatening and obtrusive first step toward treatment because the conversation will include the topic of genetic testing and not
be solely about behavior. Patients that then test positive against the AD04 genetic panel would be expected to be more likely to then
receive a prescription for AD04 (based on an external quantitative market study of 156 primary care physicians and psychiatrists that
was conducted by Ipsos-Insight LLC, who we commissioned, and that concluded a majority of genetically targeted patients currently receiving
pharmacologic treatment would be switched to a drug with the characteristics expected for AD04).
Our Substantial Proprietary Estate and Protection from Competition
We currently hold a worldwide, exclusive license
to three (3) patent families that provide us with the ability to exclude potential competitors from practicing the claimed inventions,
such as the use of ondansetron to treat any of the four (4) specified genotypes for AUD. Our licensed patent estate is expected to provide
us patent protection through 2031. Ondansetron, the active ingredient in AD04, has never been approved in a low dosage near the AD04 dose
of 0.33mg per tablet, and we believe our licensed patents will protect AD04 from any competitor that attempts to bring to market an ondansetron
dose at or near the AD04 dose for treatment of patients having one or more of the four target genotypes.
We believe use of the currently marketed doses
“off-label” will not be significant due to (i) the lack of demonstrated efficacy at currently marketed doses, (ii) potential
safety concerns if the currently marketed doses are used chronically as is expected to be necessary for treating AUD, and (iii) cutting
the smallest currently marketed dose into the 12 pieces that would be necessary to achieve the AD04 dose is deemed by us to be impractical
and likely to result in inaccurate dosing.
Experienced Leadership
Our management, advisors and board of directors
have extensive experience in pharmaceutical development, the clinical trial and regulatory approval processes, drug commercialization,
financing capital-intensive projects, and developing new markets for pharmaceutical agents. Members of our team have previously worked
in senior management and senior officer positions, or led significant research initiatives at Indivior, Shire, Viagene, Collateral Therapeutics,
Krystal Biotech, Sucampo Pharmaceuticals, GlaxoSmithKline, Osiris Therapeutics, Yumanity Therapeutics, Delix Therapeutics, and Aravive
in a broad range of therapeutic areas. Our management and board members have particular expertise in the science and development of addiction
related drugs and bringing new drugs to the market.
Our Strategy for AD04 and Addiction Related
Diseases and Disorders
We are developing pharmaceutical treatments for
addictions, addictive disorders, and related diseases and disorders. Our business strategy is to advance AD04, our lead investigational
drug candidate, toward regulatory approval for alcohol use disorder in the United States, the European Union, and then eventually other
territories. We subsequently plan to develop label expansions into other indications (e.g., opioid use disorder, other drug addictions,
obesity, smoking cessation, eating disorders and anxiety).
Our goals in executing this strategy are to keep
capital requirements to a minimum, expedite product development, gain access to clinical research and manufacturing expertise that will
advance product development, approval and eventual market uptake of our product, and rely on a well-defined and carefully executed intellectual
property strategy in order to position our products with long-term, defensible, competitive advantages. Execution of this strategy may
include seeking grant funding and funding from partners and collaborators when available on terms we believe to be favorable to us.

As consideration for the rights granted in the
license agreement, we are obligated to pay UVA LVG yearly license fees and milestone payments, and a royalty based on net sales of products
covered by the patent-related rights set forth above. More specifically, upon commencement of the license we issued to UVA LVG Class A
Units (which was equal to four percent (4%) of our equity on the date of issuance) as a license issue. We are obligated to pay UVA LVG
(i) annual minimum royalties of $40,000 commencing in 2017; (ii)a $20,000 milestone payments that was originally due upon dosing the first
patient under a Phase 3 human clinical trial of a licensed product but has been paid in full, $155,000 upon the earlier of the completion
of a Phase 3 trial of a licensed product or the partnering of the licensed or sale of our company, which was paid in 2022 with completion
of the ONWARD trial, $275,000 upon acceptance of an NDA by the FDA, and $1,000,000 upon approval for sale of AD04 in the U.S., Europe
or Japan; and (iii) royalties equal to a 2% and 1% of net sales of licensed products in countries in which a valid patent exists or does
not exist, respectively, with royalties paid quarterly. In the event of a sublicense to a third party, we are obligated to pay royalties
to UVA LVG equal to a percentage of what we would have been required to pay to UVA LVG had we sold the products under sublicense ourselves.
In addition, we are required to pay to UVA LVG 15% of any sublicensing income. The license agreement, as amended on May 18, 2016 and further
amended on August 15, 2017, December 14, 2017, and October 21, 2024 sets forth specific milestones completion deadlines including using
commercially reasonable efforts to submit an NDA by March 31, 2028 and commence commercialization of an FDA approved product by March
31, 2029. The license agreement may be terminated by UVA LVG upon sixty (60) days written notice if we breach our obligations thereunder,
