Overview

We are a clinical-stage pharmaceutical company committed to the global development and commercialization of cytisinicline for smoking cessation and nicotine addiction. With more than one billion smokers globally and over 30 million smokers in the United States alone, smoking remains the leading cause of preventable disease and death, responsible for more than eight million deaths annually worldwide. Our primary focus is to address this global epidemic.

We also plan to expand our focus to address other methods of nicotine addiction such as e-cigarettes/vaping. The use of e-cigarettes continues to be widespread, with most recent reports from the Centers for Disease Control and Prevention indicating nearly 11 million adult users in the United States alone in 2019. While e-cigarettes have been historically viewed as less harmful than combustible cigarettes, their long-term safety remains controversial. In a recent study that we conducted surveying approximately 500 users of nicotine vaping devices or e-cigarettes, approximately 73% of participants responded that they intend to quit vaping within the next three to twelve months. Of those who intended to quit even sooner, within the next 3 months, more than half stated they would be extremely likely to try a new prescription product to help them do so. We believe that cytisinicline, if approved, could be the first prescription drug indicated for vape and e-cigarette users who are ready to quit their nicotine addiction.



                                       18

--------------------------------------------------------------------------------

Our management team has significant experience in growing emerging companies focused on the development of under-utilized pharmaceutical compounds to meet unmet medical needs. We intend to use this experience to develop and ultimately commercialize cytisinicline either directly or via strategic collaborations.

Cytisinicline is an established smoking cessation treatment that has been approved and marketed in Central and Eastern Europe by Sopharma AD, or Sopharma, for over 20 years. We are evaluating an improved dosing and administration of cytisinicline that is expected to improve compliance and outcomes for smokers. We have an exclusive license and supply agreement with Sopharma for the development and commercialization of cytisinicline outside of Sopharma's territories which are predominately located in Central and Eastern Europe. It is estimated that over 20 million people have used Sopharma's cytisinicline product to help treat nicotine addiction, including over 2,700 smokers in investigator-conducted, Phase 3 clinical trials in Europe and New Zealand.

Cytisinicline is a naturally occurring, plant-based alkaloid. Cytisinicline is structurally similar to nicotine and has a well-defined, dual-acting mechanism of action that is both agonistic and antagonistic. It is believed to aid in smoking cessation and the treatment of nicotine addiction by interacting with nicotine receptors in the brain by reducing the severity of nicotine withdrawal symptoms through agonistic effects on nicotine receptors and by reducing the reward and satisfaction associated with nicotine through antagonistic properties.

In 2018, the U.S. Adopted Names Council adopted cytisinicline as the non-proprietary, or generic, name for the substance also known as cytisine.

We have no products approved for commercial sale and have not generated any revenue from product sales to date. We have never been profitable and have incurred operating losses in each year since inception. Our net loss was $18.0 million for the six months ended June 30, 2022. As of June 30, 2022, we had an accumulated deficit of $111.6 million, cash and cash equivalents balance of $29.4 million and a positive working capital balance of $25.8 million. For the six months ended June 30, 2022, net cash used in operating activities was $15.1 million.

Substantial doubt exists as to our ability to continue as a going concern. Our ability to continue as a going concern is subject to material uncertainty and dependent on our ability to obtain additional financing. We expect to incur significant expenses and increasing operating losses for at least the next several years as we continue our clinical development of, and seek regulatory approval for, cytisinicline and add personnel necessary to operate as a public company with an advanced clinical candidate. We expect that our operating losses will fluctuate significantly from quarter to quarter and year to year due to timing of clinical development programs and efforts to achieve regulatory approval. Without additional funds, we may be forced to delay, scale back or eliminate some of our research and development activities or other operations and potentially delay product development in an effort to provide sufficient funds to continue our operations. If any of these events occurs, our ability to achieve our development and commercialization goals would be adversely affected.

Our current resources are insufficient to fund our planned operations for the next twelve months. We will continue to require substantial additional capital to continue our clinical development activities. Accordingly, we will need to raise substantial additional capital to continue to fund our operations from the sale of our securities, partnering arrangements or other financing transactions in order to finance the commercialization of our product candidate. The amount and timing of our future funding requirements will depend on many factors, including the pace and results of our clinical development efforts. The uncertainty with respect to our operations and the market generally due to the COVID-19 pandemic and increasing interest rates and inflation may also make it challenging to raise additional capital on favorable terms, if at all. Failure to raise capital as and when needed, on favorable terms or at all, will have a negative impact on our financial condition and our ability to develop our product candidate.

Our accompanying financial results have been prepared assuming we will continue to operate as a going concern, which contemplates the realization of assets and liabilities and commitments in the normal course of business. The financial results do not include any adjustments to the amounts and classification of assets and liabilities that might be necessary should we be unable to continue as a going concern. Such adjustments could be material.

Cytisinicline Ongoing and Recent Clinical Developments

Company-Sponsored Clinical Trials for a Smoking Cessation Indication

Completed Phase 3 ORCA-2 Trial In April 2022, we announced positive topline results for the Phase 3 ORCA-2 clinical trial. ORCA-2 was initiated in October 2020 and evaluated the efficacy and safety of 3 mg cytisinicline dosed three times daily compared to placebo in 810 adult smokers at 17 clinical sites in the United States. ORCA-2 participants were randomized to one of three study arms to determine the smoking



                                       19

--------------------------------------------------------------------------------

cessation efficacy and safety profile of cytisinicline when administered for either 6 or 12 weeks, compared to placebo. All subjects received standard behavioral support and were assigned to one of the following groups:


  • Arm A: 12 weeks of placebo


  • Arm B: 6 weeks of cytisinicline, followed by 6 weeks of placebo


  • Arm C: 12 weeks of cytisinicline

The ORCA-2 study had two independent primary endpoints that evaluated the success of smoking abstinence for both 6-week and 12-week durations of cytisinicline treatment, compared to placebo. The primary endpoints for ORCA-2 were biochemically verified continuous abstinence measured during the last 4 weeks of each treatment duration. Both the 6- and 12-week cytisinicline treatments demonstrated significantly better quit rates than placebo with odds ratios of 8.0 and 6.3, respectively. The odds ratio, or OR, is a standard measure of association between an exposure (cytisinicline treatment) and an outcome (continuous smoking abstinence).


   •  Subjects who received 12 weeks of cytisinicline treatment had 6.3 times
      higher odds, or likelihood, to have quit smoking during the last 4 weeks of
      treatment compared to subjects who received placebo (p<0.0001). The
      abstinence rate during weeks 9-12 was 32.6% for cytisinicline compared to
      7.0% for placebo.


   •  Subjects who received 6 weeks of cytisinicline treatment had 8 times higher
      odds, or likelihood, to have quit smoking during the last 4 weeks of
      treatment compared to subjects who received placebo (p<0.0001). The
      abstinence rate during weeks 3-6 was 25.3% for cytisinicline compared to
      4.4% for placebo.


                               [[Image Removed]]

The secondary endpoints measured continuous abstinence after treatment out to 24 weeks. Both the 6- and 12-week secondary endpoints for continuous abstinence demonstrated significantly better quit rates for cytisinicline treated subjects than placebo. The continuous abstinence rate from week 9 to 24 was 21.1% for the 12-week cytisinicline arm compared to 4.8% for placebo, with an odds ratio of 5.3 (p<0.0001). The continuous abstinence rate from week 3 to 24 was 8.9% for the 6-week cytisinicline arm compared to 2.6% for placebo, with an odds ratio of 3.7 (p=0.0016).

A third secondary endpoint compared the two cytisinicline treatment arms and evaluated for an increased risk in relapse from week 6 to week 24 when subjects were switched to placebo during week 6 to week 12 (Arm B) instead of receiving cytisinicline for another 6 weeks during week 6 to week 12 (Arm C). The analysis showed that there was no increased risk of smoking relapse in subjects who had successfully quit smoking by week 3 through week 6 if they received placebo instead of continuing cytisinicline from week 6 to week 12.



                                       20

--------------------------------------------------------------------------------

Cytisinicline was well tolerated with no treatment-related serious adverse events reported. The most commonly reported (less than 5% overall) adverse events for placebo, 6-week cytisinicline, and 12-week cytisinicline, respectively, were:




                Placebo 6-Weeks Cytisinicline 12-Weeks Cytisinicline
Insomnia         4.8%           8.6%                   9.6%
Abnormal Dreams  3.0%           8.2%                   7.8%
Headaches        8.1%           6.7%                   7.8%
Nausea           7.4%           5.9%                   5.6%



We will continue to analyze the ORCA-2 results and expect to submit these data for publication and presentation at future medical conferences. Ongoing Phase 3 ORCA-3 Trial In January 2022, we initiated our Phase 3 ORCA-3 clinical trial. ORCA-3 is a confirmatory Phase 3 trial required for registrational approval of cytisinicline in the United States and has the same design as the Phase 3 ORCA-2 trial. The Phase 3 trial will evaluate the efficacy and safety of 3 mg cytisinicline dosed three times daily compared to placebo in 750 adult smokers at 19 clinical sites. ORCA-3 participants will be randomized to one of three study arms to evaluate cytisinicline administered for either 6 or 12 weeks, compared to placebo. All subjects will receive standard behavioral support and will be assigned to one of the following groups:


  • Arm A: 12 weeks of placebo


  • Arm B: 6 weeks of cytisinicline, followed by 6 weeks of placebo


  • Arm C: 12 weeks of cytisinicline

The primary outcome measure of success in the ORCA-3 trial is biochemically verified continuous abstinence during the last four weeks of treatment in the 6 and 12-week cytisinicline treatment arms compared with placebo. Each treatment arm will be compared independently to the placebo arm, and the trial will be determined to be successful if either or both of the cytisinicline treatment arms show a statistical benefit compared to placebo. Secondary outcome measures will be conducted to assess continued abstinence rates through six months from the start of study treatment. We expect to complete enrollment in the third quarter of 2022. Completed Phase 2 ORCA-1 Trial

In June 2019, we announced positive top line results for the Phase 2b ORCA-1 trial and defined the dose selection of 3 mg, three times daily, or TID, for our Phase 3 development. ORCA-1 was the first trial in our Ongoing Research of Cytisinicline for Addiction Program, or ORCA Program, that aims to evaluate the effectiveness of cytisinicline for smoking cessation, nicotine addiction therapy, and potential benefit in other indications.

ORCA-1 was initiated in October 2018 and evaluated 254 smokers in the United States. The trial evaluated both 1.5 mg and 3 mg doses of cytisinicline on the standard declining titration schedule as well as a more simplified TID dosing schedule, both over 25 days. The trial was randomized and blinded to compare the effectiveness of the cytisinicline doses and schedules to respective placebo groups. Subjects were treated for 25 days, provided behavioral support, and followed up for an additional four weeks to assess continued smoking abstinence after the 25-day treatment.

The primary endpoint in the study was the reduction in daily smoking, a self-reported measure. Three of the four cytisinicline treatment arms demonstrated a statistically significant reduction, p<0.05, compared to placebo. The fourth arm trended to significance (p= 0.052). Across all treatment arms, over the 25-day treatment period, subjects on cytisinicline experienced a 74-80% median reduction in the number of cigarettes smoked, compared to a 62% reduction in the placebo arms.

The secondary endpoint of the trial was a 4-week continuous abstinence rate, which is the relevant endpoint for regulatory approval. All cytisinicline treatment arms showed significant improvements in abstinence rates compared to the placebo arms. The most impressive results were observed in the 3 mg TID cytisinicline arm which demonstrated a 50% abstinence rate at week 4, compared to 10% for placebo (p<0.0001) and a continuous abstinence rate, weeks 5 through 8, of 30% for cytisinicline compared to 8% for placebo (p= 0.005). Smokers in the 3 mg TID arm had an OR of 5.04 (95% CI: 1.42, 22.32) for continuous abstinence from week 5 to week 8,



                                       21

--------------------------------------------------------------------------------

compared with placebo, meaning, smokers receiving 3 mg cytisinicline TID were 5 times more likely to stop smoking compared to subjects on placebo.

At week 4, all four cytisinicline arms demonstrated statistically significant (p<0.05) reductions in expired carbon monoxide, or CO, a biochemical measure of smoking activity. Expired CO levels had declined by a median of 71-80% in the cytisinicline treatment arms, compared to only 38% in the placebo arms. The greater reductions in expired CO levels for the cytisinicline arms versus placebo suggest that placebo-treated subjects may have over-reported their reduction in cigarettes smoked or overcompensated with greater inhalation while smoking fewer cigarettes.

Cytisinicline was well-tolerated with no serious adverse effects, or SAEs, reported. The most commonly reported (>5%) adverse effects, or AEs, across all cytisinicline treatment arms versus placebo arms were abnormal dreams, insomnia, upper respiratory tract infections, and nausea. In the 3 mg TID treatment arm versus placebo arms, the most common AEs were abnormal dreams, insomnia, and constipation (each 6% vs 2%), upper respiratory tract infections (6% vs 14%), and nausea (6% vs 10%), respectively. Compliance with study treatment was greater than 94% across all arms.

We presented the ORCA-1 results in September 2019 at the annual European meeting of the Society for Research on Nicotine and Tobacco, or SRNT, held in Oslo, Norway and the trial results were published in the journal Nicotine and Tobacco Research in April 2021. Based on the results of the ORCA-1 trial, we selected 3 mg TID for Phase 3 development. Overall, the 3 mg dose administered TID demonstrated the best overall safety and efficacy when compared to the 1.5 mg dose or the declining titration schedule evaluated in ORCA-1. At the SRNT European meeting held in September 2021, exploratory analyses were presented that showed cytisinicline treatment had an earlier onset of sustained abstinence compared to placebo and that the cytisinicline TID schedule appeared more effective for achieving sustained abstinence in smokers who had previously failed to quit on varenicline compared to the declining titration schedule.

In November 2019, we held a type C meeting with the U.S. Food and Drug Administration, or FDA, to review the ORCA-1 results and our revisions to the Phase 3 clinical program using the simplified 3 mg TID dosing schedule. The FDA agreed that the 3 mg TID dosing schedule was acceptable.




Company-Sponsored Clinical Trials for an E-cigarette (nicotine vaping) Cessation
Indication
Ongoing Phase 2 ORCA-V1 Clinical Trial
In July 2021, we announced that we were awarded a grant from the National
Institute on Drug Abuse, or NIDA, of the National Institutes of Health, or NIH,
to evaluate the use of cytisinicline as a treatment for cessation of nicotine
e-cigarette use. This initial grant award, in the amount of $320,000, commenced
on August 1, 2021, and was utilized to complete critical regulatory and clinical
operational activities, such as protocol finalization, clinical trial site
identification, and submission of an Investigational New Drug Application, or
IND, to the FDA for investigating cytisinicline in nicotine e-cigarette users.
In November 2021, we announced that the FDA had completed their review and
accepted the IND application to investigate cytisinicline as a cessation
treatment in this population. In June 2022, following NIH review of completed
milestones, we announced that we were awarded the next grant funding from the
NIDA in the amount of approximately $2.5 million to conduct the ORCA-V1 Phase 2
Clinical trial.

In June 2022, we announced we had initiated the ORCA-V1 Phase 2 Clinical trial. ORCA-V1 will evaluate the efficacy and safety of 3 mg cytisinicline dosed 3 times daily compared to placebo in approximately 150 adult e-cigarette users at five clinical trial locations in the United States. Participants will be randomized to receive cytisinicline or placebo for 12 weeks in combination with standard cessation behavioral support. Subject to timing of enrollment and other factors, top line results from the ORCA-V1 study are anticipated in the first half of 2023.

The full grant award of $2.8 million is expected to cover approximately half of the total ORCA-V1 clinical study costs. The Primary Investigators for the grant are our Chief Medical Officer, Dr. Cindy Jacobs, and Dr. Nancy Rigotti, Professor of Medicine at Harvard Medical School and Director, Tobacco Research and Treatment Center, Massachusetts General Hospital.

Other Recent Investigator-Sponsored Clinical Trials

In June 2020, we announced the topline results from the independent, investigator-sponsored Phase 3 RAUORA trial. RAUORA was a non-inferiority study comparing cytisinicline to Chantix (varenicline) in M?ori (indigenous New Zealanders) and wh?nau (family) of M?ori. The study was led by Dr. Natalie Walker, Associate Professor at the University of Auckland, and was funded by the Health Research Council of New Zealand. The study enrollment was planned for 2,140 subjects. In total, 1,105 M?ori or wh?nau expressed



                                       22

--------------------------------------------------------------------------------

interest in participating in the study and a total of 679 were randomized to receive either cytisinicline or varenicline. The average age of participants in the trial was 43 years and approximately 70% of the participants were women.

The study compared cytisinicline administered on a schedule of 25 days of declining titration followed by twice-daily dosing for a total of 12 weeks with varenicline administered on a schedule of seven days of inclining titration followed by twice-daily dosing for a total of 12 weeks. The primary endpoint was a comparison of biochemically confirmed continuous abstinence rates at six months, and the trial was designed to assess if the two agents were non-inferior to each other.

The primary endpoint of the non-inferiority trial was to demonstrate that cytisinicline quit rates would be no less than 10% lower than the quit rates for varenicline. Topline results indicated that the RAUORA trial achieved its primary endpoint in showing that cytisinicline plus behavioral support was at least as effective as varenicline plus behavioral support at six months. Cytisinicline met the pre-specified non-inferiority endpoint and was trending towards superiority with an Absolute Risk Difference of +4.29 in favor of cytisinicline (95% CI -0.22 to 8.79), demonstrating a 4.29% improvement in quit rates in favor of cytisinicline. Specifically, continuous abstinence rates at six months, verified by expired CO, were 12.1% for cytisinicline compared to 7.9% for varenicline. The Relative Risk was 1.55 on an intent-to-treat basis, indicating that subjects in the cytisinicline arm were approximately one and a half times more likely to have quit smoking at six months compared to subjects who received varenicline.

Additionally, significantly fewer overall AEs were reported in cytisinicline-treated subjects (Relative Risk 0.56, 95% CI 0.49 to 0.65, p<0.001). Notably, of the subjects who experienced adverse events, cytisinicline subjects reported significantly less nausea, insomnia and vivid dreams (p<0.05).

The final RAUORA trial results and additional analyses were presented at the SRNT European Annual Meeting in September 2020 and were published in the journal Addiction in March 2021. Also presented at the SRNT Europe Annual Meeting in September 2020 were results from a preclinical study conducted at the University of Cambridge Department of Biochemistry. The study was designed to examine the in vitro binding characteristics of cytisinicline compared to varenicline at the human 5-HT3 receptor. Using a radioligand antagonist displacement design, the study reported an IC50 of 0.50 mM for cytisinicline and 0.25 µM for varenicline, representing a 2000-greater fold agonist binding affinity to the 5-HT3 receptor for varenicline compared to cytisinicline. Agonist activation of 5-HT3 receptors in the brain stem has been shown to induce nausea and vomiting. The data demonstrating the difference in binding potency at the 5-HT3 receptor provide potential rationale for the lower overall incidence of adverse events reported for cytisinicline compared to varenicline.

Non-clinical Studies

Non-clinical toxicology studies were sponsored by the National Center for Complementary and Integrative Health, or NCCIH, a division of the NIH and by the National Cancer Institute, or NCI, to assist in our IND for investigating cytisinicline as a smoking cessation treatment. We filed this IND application for cytisinicline with the FDA in 2017, which included the NCCIH sponsored non-clinical studies. Additional NCCIH and NCI sponsored non-clinical toxicology studies were later submitted in support for initiating our Phase 3 program.

Non-clinical toxicology studies that will be required for a New Drug Application, or NDA, include two longer-term chronic toxicology studies and two carcinogenicity studies, which are in distinct stages of execution as company-sponsored studies. Two chronic toxicology studies have been completed and submitted to the FDA. Additionally, both carcinogenicity studies have been completed and will be submitted to FDA during the third quarter of 2022.

Impact of COVID-19 Pandemic

As a result of the COVID-19 pandemic, we have experienced disruptions in our operations, liquidity, supply chain, facilities, and clinical trials. We may in the future experience more significant delays in enrollment, participant dosing, distribution of clinical trial materials, study monitoring and data analysis that could materially adversely impact our business, results of operations and overall financial performance in future periods. Specifically, we may experience impact from changes in how we and companies worldwide conduct business due to the COVID-19 pandemic, including but not limited to restrictions on travel and in-person meetings, delays in site activations and enrollment of clinical trials, prioritization of hospital resources toward pandemic effort, delays in review by the FDA, and disruptions in our supply chain for our product candidates. The extent of the impact on the COVID-19 pandemic on our operational and financial performance is uncertain and cannot be predicted. As of the filing date of this Quarterly Report on Form 10-Q, the extent to which the COVID-19 pandemic has impacted our financial condition, results of operations or guidance has been minimal. The effect of any additional COVID-19 pandemic issues will not be fully reflected in our results of operations and overall financial performance until future periods. See the section titled "Risk Factors" for further discussion of the possible impact of the COVID-19 pandemic on our business.

License & Supply Agreements

Sopharma License and Supply Agreements

We are party to a license agreement, or the Sopharma License Agreement, and a supply agreement, or the Sopharma Supply Agreement, with Sopharma. Pursuant to the Sopharma License Agreement, we were granted access to all available manufacturing, efficacy and safety data related to cytisinicline, as well as a granted patent in several European countries related to new oral dosage forms of cytisinicline providing enhanced stability. Additional rights granted under the Sopharma License Agreement include the exclusive use of, and the right to sublicense, certain cytisinicline trademarks in all territories described in the Sopharma License Agreement. Under the Sopharma License Agreement, we agreed to pay a nonrefundable license fee. In addition, we agreed to make certain royalty payments equal to a mid-single digit percentage of all net sales of cytisinicline products in our territory during the term of the Sopharma License Agreement, including those sold by a third party pursuant to any sublicense which may be granted by us. To date, any amounts paid to Sopharma pursuant to the Sopharma License Agreement have been immaterial.

University of Bristol License Agreement

In July 2016, we entered into a license agreement with the University of Bristol, or the University of Bristol License Agreement. Under the University of Bristol License Agreement, we received exclusive and nonexclusive licenses from the University of Bristol to certain patent and technology rights resulting from research activities into cytisinicline and its derivatives, including a number of patent applications related to novel approaches to cytisinicline binding at the nicotinic receptor level.

In consideration of rights granted by the University of Bristol, we paid a nominal license fee and agreed to pay amounts of up to $3.2 million, in the aggregate, tied to a financing milestone and to specific clinical development and commercialization milestones resulting from activities covered by the University of Bristol License Agreement. Additionally, if we successfully commercialize any product candidates subject to the University of Bristol License Agreement, we are responsible for royalty payments in the low-single digits and payments up to a percentage in the mid-teens of any sublicense income, subject to specified exceptions, based upon net sales of such licensed products.

On January 22, 2018, we and the University of Bristol entered into an amendment to the University of Bristol License Agreement. Pursuant to the amended University of Bristol License Agreement we received exclusive rights for all human medicinal uses of cytisinicline across all therapeutic categories from the University of Bristol from research activities into cytisinicline and its derivatives. In consideration of rights granted by the amended University of Bristol License Agreement, we agreed to pay an initial amount of $37,500 upon the execution of the amended University of Bristol License Agreement, and additional amounts of up to $1.7 million, in the aggregate, tied to a financing milestone and to specific clinical development and commercialization milestones resulting from activities covered by the amended University of Bristol License Agreement, in addition to amounts under the original University of Bristol License Agreement of up to $3.2 million in the aggregate, tied to specific financing, development and commercialization milestones. Additionally, if we successfully commercialize any product candidate subject to the amended University of Bristol License Agreement or to the original University of Bristol License Agreement, we will be responsible, as provided in the original University of Bristol License Agreement, for royalty payments in the low-single digits and payments up to a percentage in the mid-teens of any sublicense income, subject to specified exceptions, based upon net sales of such licensed products. Up to June 30, 2022, we had paid the University of Bristol $125,000 pursuant to the University of Bristol License Agreement.

Research and Development Expenses

Research and development, or R&D, expenses consist primarily of costs for clinical trials, contract manufacturing, personnel costs, milestone payments to third parties, facilities, regulatory activities, non-clinical studies and allocations of other R&D-related costs. External expenses for clinical trials include fees paid to clinical research organizations, clinical trial site costs and patient treatment costs.

We manage our clinical trials through contract research organizations and independent medical investigators at our sites and at hospitals and expect this practice to continue. Due to our ability to utilize resources across several projects, we do not record or maintain information regarding the indirect operating costs incurred for our R&D programs on a program-specific basis. In addition, we believe that allocating costs on the basis of time incurred by our employees does not accurately reflect the actual costs of a project.

We expect our R&D expenses to increase for the foreseeable future as we continue to conduct our ongoing non-clinical studies, and initiate new clinical trials and registration-enabling activities. The process of conducting clinical trials and non-clinical studies necessary to obtain regulatory approval is costly and time consuming and we may never succeed in achieving marketing approval for cytisinicline. (See "Item 1A. Risk Factors-Risks Related to the Development of Our Product Candidate Cytisinicline.")

Successful development of cytisinicline is highly uncertain and may not result in an approved product. We cannot estimate completion dates for development activities or when we might receive material net cash inflows from our R&D projects, if ever. We anticipate we will make determinations as to which markets, and therefore, which regulatory approvals, to pursue and how much funding to direct toward achieving regulatory approval in each market on an ongoing basis in response to our ability to enter into new strategic alliances with respect to each program or potential product candidate, the scientific and clinical success of each future product candidate, and ongoing assessments as to each future product candidate's commercial potential. We will need to raise additional capital and may seek additional strategic alliances in the future in order to advance our various programs.

Our projects or intended R&D activities may be subject to change from time to time as we evaluate results from completed studies, our R&D priorities and available resources.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and related costs for our personnel in executive, finance and accounting, corporate communications and other administrative functions, as well as consulting costs, including market research, business consulting, human resources and intellectual property. Other costs include professional fees for legal and auditing services, insurance and facility costs.

Results of Operations

For the three and six months ended June 30, 2022

Research and development expenses

Our R&D expenses for our clinical development program for the three and six months ended June 30, 2022 and 2021 were as follows (in thousands):



                                            Three Months Ended          Six Months Ended
                                                 June 30,                   June 30,

Clinical development programs:
Cytisinicline                             $    7,207      $ 9,227     $ 11,595     $ 14,869

Total research and development expenses $ 7,207 $ 9,227 $ 11,595 $ 14,869

R&D expenses for the three and six months ended June 30, 2022 decreased to $7.2 million and $11.6 million, respectively, from $9.2 million and $14.9 million for the three and six months ended June 30, 2021, respectively. The decrease in the three and six months ended June 30, 2022 as compared to the same periods in 2021 was primarily due to timing of the initiation of our Phase 3 ORCA-3 trial, which initiated in January 2022, and our Phase 3 ORCA-2 trial, which initiated in October 2020 and ramped up through the first half of 2021. We anticipate R&D expenses to increase in the second half of 2022 with the initiation of the ORCA-V1 trial.

General and administrative expenses

Our general and administrative expenses for the three and six months ended June 30, 2022 and 2021 were as follows (in thousands):




                                              Three Months Ended          Six Months Ended
                                                   June 30,                   June 30,

Total general and administrative expenses $ 2,866 $ 2,075 $ 5,704 $ 4,417

General and administrative expenses for the three and six months ended June 30, 2022 increased to $2.9 million and $5.7 million, respectively, from $2.1 million and $4.4 million for the three and six months ended June 30, 2021, respectively. The increase was primarily due to higher clinical trial media and awareness expenses, employee expenses associated with stock-based compensation, higher legal expenses as a result of increased patent application activities and increase in insurance premiums.



                                       25

--------------------------------------------------------------------------------

Liquidity and Capital Resources

We have incurred an accumulated deficit of $111.6 million through June 30, 2022 and we expect to incur substantial additional losses in the future as we operate our business and continue or expand our R&D activities and other operations. We have not generated any revenue from product sales to date, and we may not generate product sales revenue in the near future, if ever. As of June 30, 2022, we had a cash and cash equivalents balance of $29.4 million and a positive working capital balance of $25.8 million. We believe that our existing cash, cash equivalents and restricted cash, will be sufficient for us to fund our current operating expenses and capital expenditures into 2023.

The financial results have been prepared assuming we will continue to operate as a going concern, which contemplates the realization of assets and liabilities and commitments in the normal course of business.

Substantial doubt exists as to our ability to continue as a going concern. Our ability to continue as a going concern is subject to material uncertainty and dependent on our ability to obtain additional financing. There is no assurance that we will obtain financing from other sources. The uncertainty with respect to our operations and the capital markets market generally may make it challenging to raise additional capital on favorable terms, if at all. The uncertainty with respect to our operations and the market generally due to the COVID-19 pandemic and increasing interest rates and inflation may also make it challenging to raise additional capital on favorable terms, if at all. We have historically financed our operations through equity and debt financings. Without additional funds, we may be forced to delay, scale back or eliminate some of our research and development activities or other operations and potentially delay product development in an effort to provide sufficient funds to continue our operations. If any of these events occur, our ability to achieve our development and commercialization goals would be adversely affected. In addition, we expect to incur significant expenses and increasing operating losses for at least the next several years as we continue our clinical development of, and seek regulatory approval for, cytisinicline and add personnel necessary to operate as a public company with an advanced clinical candidate. We expect that our operating losses will fluctuate significantly from quarter to quarter and year to year due to timing of clinical development programs and efforts to achieve regulatory approval.

Our current resources are insufficient to fund our planned operations for the next twelve months. We will continue to require substantial additional capital to continue our clinical development activities. Accordingly, we will need to raise substantial additional capital to continue to fund our operations from the sale of our securities, partnering arrangements or other financing transactions in order to finance the commercialization of our product candidate. The amount and timing of our future funding requirements will depend on many factors, including the pace and results of our clinical development efforts. Failure to raise capital as and when needed, on favorable terms or at all, will have a negative impact on our financial condition and our ability to develop our product candidate.

The consolidated financial results do not include any adjustments to the amounts and classification of assets and liabilities that might be necessary should we be unable to continue as a going concern. Such adjustments could be material.

We did not have during the periods presented, and we do not currently have, any commitments or obligations, including contingent obligations, arising from arrangements with unconsolidated entities or persons that have or are reasonably likely to have a material current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, cash requirements or capital resources.

May 2021 Public Offering

On May 27, 2021, we completed an underwritten public offering of our securities, pursuant to which we sold an aggregate of 3,285,714 shares of our common stock, including 428,571 shares subject to the underwriter's option to purchase additional shares, or the May Shares. The May Shares were sold at the public offering price of $7.00 per share.

The underwritten public offering raised total gross proceeds of approximately $23.0 million and after deducting approximately $1.7 million in underwriting discounts and commissions and offering expenses, we received net proceeds of approximately $21.3 million. The underwriting discounts and commissions and offering expenses have been charged against the gross proceeds.

Convertible Debt and Term Loan

On December 22, 2021, we entered into a $25.0 million contingent convertible debt agreement, or Original Debt Agreement, with Silicon Valley Bank, or SVB, and SVB Innovation Credit Fund VIII, L.P., or, together with SVB, the Lenders. As part of the Original Debt Agreement, the Lenders funded $15.0 million in the form of convertible indebtedness, or Convertible Debt, at closing. On April 26, 2022, we entered into (i) a loan and security agreement, or Loan Agreement, with SVB for the remaining $10.0 million remaining



                                       26

--------------------------------------------------------------------------------

in the Original Debt Agreement, pursuant to which SVB provided a commitment to extend term loans having an aggregate original principal amount of up to $10.0 million, or Term Loans, and (ii) a first amendment to the Original Debt Agreement, or the Amendment, and as amended by the Amendment, the Debt Agreement.

Under the terms of the agreement, the Convertible Debt matures on December 22, 2023 and may be extended to December 22, 2024 upon our written request and SVB's approval on or prior to December 22, 2023. The Convertible Debt will accrue interest at the aggregate of (a) a floating rate per annum equal to the greater of (i) 2.25% and (ii) the prime rate minus 1.0%, which interest is payable in cash monthly in arrears, and (b) 7.0% per annum, which interest shall compound monthly.

Subject to certain terms and conditions, the Lenders may convert all or any part of the outstanding Convertible Debt and accrued and unpaid interest at any time prior to maturity into shares of our common stock at a conversion price equal to $9.34 per share, subject to customary anti-dilution adjustments. Additionally, all outstanding Convertible Debt, including accrued and unpaid interest, will mandatorily convert into shares of our common stock, at the conversion price, on such date, if any, when the closing price per share of our common stock has been equal to or greater than $24.00 for thirty consecutive trading days prior to such date.

We have the right, or Call Right, at any time to repay and retire all (but not less than all) of the outstanding Convertible Debt and accrued and unpaid interest, if any, prior to its conversion by payment of a premium determined based on the date of such repayment equal to:



     •   125% of the principal amount of the Convertible Debt including accrued
         paid-in-kind interest, or PIK, if the Call Right is exercised on or
         before the 18-month anniversary of the date of the Debt Agreement; and


    •    150% of the principal amount of the Convertible Debt including accrued
         PIK, if the Call Right is exercised after the 18-month anniversary of the
         date of the Debt Agreement,


in either case together with all accrued and unpaid interest on the principal balance of the Convertible Debt. If the Call Right is exercised by us, the Lenders will retain certain lookback rights in the event we enter into an agreement to be acquired in the twelve months following the exercise of the Call Right. We agreed to grant the Lenders a security interest in virtually all of our assets, including our patents and other intellectual property as security for our obligations under the Debt Agreement.

Subject to the terms and conditions of the Loan Agreement, we may borrow term loans under the Loan Agreement until April 30, 2023. Amounts borrowed under the Loan Agreement will incur interest at a floating rate equal to the greater of 3.50% and the Wall Street Journal, or WSJ, prime rate, and will be subject to interest only payments through April 30, 2024. Commencing on May 1, 2024, the outstanding loans under the Loan Agreement will be repaid in 24 consecutive equal monthly installments of principal plus accrued and unpaid interest. The Term Loans mature on April 1, 2026. Upon the earliest to occur of the maturity date, repayment of the Term Loans in full, acceleration of the loans or termination of the Loan Agreement, we will be required to pay a final payment equal to the aggregate principal amount of the Term Loan advances extended by SVB multiplied by 6.0%. Our obligations under the Loan Agreement are secured by substantially all of our assets, other than our intellectual property.

Upon and after borrowing under the Loan Agreement, we must comply with certain financial covenants as set forth in the Loan Agreement and the Amendment, including a minimum liquidity ratio of at least 1.25 to 1.00, or at our election after receiving at least $30 million in net cash proceeds from the issuance and sale of equity securities, a minimum market capitalization of at least $250 million. The Loan Agreement also contains customary affirmative and restrictive covenants, including covenants regarding the incurrence of additional indebtedness or liens, investments, transactions with affiliates, delivery of financial statements, payment of taxes, maintenance of insurance, dispositions of property, mergers or acquisitions, among other customary covenants. We are also restricted from paying dividends or making other distributions or payments on its capital stock, subject to limited exceptions. The Loan Agreement includes customary representations and warranties, events of default and termination provisions. In addition to the financial covenants described above, the Amendment makes certain other changes to the Original Debt Agreement related to our entry into the Loan Agreement. No amounts have been drawn on the Term Loans.

At-the-Market Sales Agreement

On December 21, 2021, we entered into an At-the-Market Offering Sales Agreement, or ATM, with Virtu Americas, LLC, as sales agent, pursuant to which we may sell shares of common stock with an aggregate offering price of up to $25 million.

During the six months ended June 30, 2022, we sold 200,000 shares of our common stock pursuant to the ATM, which resulted in gross proceeds of $1.5 million. Since entry into the ATM, from December 31, 2021 through August 10, 2022, we offered and sold an aggregate of 200,000 shares of our common stock. These aggregate sales resulted in gross proceeds to us of approximately $1.5 million and offering expenses of $31,000. As of August 10, 2022, shares of our common stock having an aggregate value of approximately $23.5 million remained available for sale under the ATM.

Cash Flows

Cash Used in Operating Activities

For the six months ended June 30, 2022, net cash used in operating activities was $15.1 million compared to $15.5 million for the six months ended June 30, 2021. The decrease in cash used in operations in the 2022 period as compared to the 2021 period was primarily attributable to higher R&D expense in 2021 as a result of timing of the initiation of our Phase 3 ORCA-3 trial, which initiated in January 2022, and our Phase 3 ORCA-2 trial, which initiated in October 2020 and ramped up through the first half of 2021.

Cash Provided in Financing Activities

For the six months ended June 30, 2022, net cash provided by financing activities was $1.5 million compared to $21.7 million for the six months ended June 30, 2021. Net cash provided by financing activities in the six months ended June 30, 2022 relates to proceeds received from ATM sales and warrant exercises. Net cash provided by financing activities in the six months ended June 30, 2021, relates to proceeds received from our May 2021 public offering and warrant exercises.

Commitments and Contingencies

We previously disclosed certain contractual obligations and contingencies and commitments relevant to us within the financial statements and Management's Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on March 10, 2022. There have been no material changes to our "Contractual Obligations" table in Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" of our 2021 Form 10-K. For more information regarding our current contingencies and commitments, see Note 8 to the financial statements included above.

Critical Accounting Policies and Estimates

The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts and related disclosures. We have discussed those estimates that we believe are critical and require the use of complex judgment in their application in our audited financial statements for the year ended December 31, 2021 in our Annual Report on Form 10-K filed with the SEC, on March 10, 2022. Since December 31, 2021, there have been no material changes to our critical accounting policies or the methodologies or assumptions we apply under them.

New Accounting Standards

See Note 2, "Accounting Policies," of the consolidated financial statements for information related to the adoption of new accounting standards in 2022, none of which had a material impact on our financial statements, and the future adoption of recently issued accounting standards, which we do not expect to have a material impact on our financial statements. Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that material information required to be disclosed in our periodic reports filed or submitted under the Securities Exchange Act of 1934, as amended, or the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Our disclosure controls and procedures are also designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act are accumulated and communicated to our management, including our principal executive officer and principal financial officer as appropriate, to allow timely decisions regarding required disclosure.

During the quarter ended June 30, 2022, we carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective, as of the end of the period covered by this report.

Changes in Internal Control Over Financial Reporting

We have not made any changes to our internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended June 30, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.



                                       28

--------------------------------------------------------------------------------

Limitations on Effectiveness of Controls

Our management does not expect that our disclosure controls and procedures or our internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected.
