Overview

We are a clinical-stage pharmaceutical company committed to the global (excluding Central & Eastern Europe plus other territories) development and commercialization of cytisinicline for smoking cessation and nicotine addiction. Our primary focus is to address the global smoking and nicotine addiction epidemic, which is a leading cause of preventable death and is responsible for more than eight million deaths annually worldwide. We may expand our focus to address other methods of nicotine addiction such as e-cigarettes/vaping.

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 for over 20 years under the brand name Tabex™. It is estimated that over 20 million people have used cytisinicline to help treat nicotine addiction, including over 2,000 patients in investigator-conducted, Phase 3 clinical trials in Europe and New Zealand. Both trials were published in the New England Journal of Medicine in September 2011 and December 2014, respectively.

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



                                       22

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

through agonistic binding to nicotine receptors and by reducing the reward and satisfaction associated with nicotine through antagonistic properties.

Non-clinical toxicology studies were sponsored by the National Center for Complementary and Integrative Health, or NCCIH, a division of the National Institutes of Health, or NIH, and by the National Cancer Institute, or NCI, to assist in our Investigational New Drug Application, or IND. In June 2017, we filed our IND application for cytisinicline with the United States Food and Drug Administration, or FDA, which included the NCCIH sponsored non-clinical studies. Additional non-clinical reproductive toxicology studies have also been conducted by NCCIH and NCI, with three such studies already submitted to the FDA. Other 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. One of the chronic toxicology studies has been completed and submitted to FDA. The 13-Week Interim report for the second 39-Week chronic toxicology study has been completed and submitted to FDA with the 39-Week study report expected to be completed and submitted to FDA in the fourth quarter 2020. Additionally, one of the carcinogenicity studies is currently in progress, while the second carcinogenicity study is planned for initiation during Phase 3 development.

In August 2017, we initiated a Phase 1 clinical study evaluating the effect of food on the bioavailability of cytisinicline in normal healthy volunteers. We completed the food effect study and announced the results in November of 2017 demonstrating similar bioavailability of cytisinicline in fed and fasted subjects.

In October 2017, we initiated a clinical study assessing the repeat-dose pharmacokinetics, or PK, and pharmacodynamics, or PD, effects of 1.5 mg and 3 mg cytisinicline in 36 healthy volunteer smokers when administered over the standard 25-day course of treatment as marketed by Sopharma in their territories. Of the 36 subjects, 24 were to be 18-65 years of age and 12 were to be greater than 65 years of age. Final results were presented at the Annual Meeting of the Society for Research on Nicotine and Tobacco, or SRNT, in February 2019. The study randomized a total of 26 subjects, which included only 2 of the intended 12 subjects of an age greater than 65, due to difficulty enrolling within this age group. All 26 subjects completed the study. Predictable increases in plasma cytisinicline concentrations were observed with increasing unit dosing from 1.5 mg to 3 mg. Smokers in the study were not required to have a designated or predetermined quit date. Overall, subjects had an 80% reduction in cigarettes smoked, 82% reduction in expired carbon monoxide, and 46% of the subjects achieved biochemically verified smoking abstinence by day 26. Subjects who received 3 mg cytisinicline over the 25 days had a trend for higher smoking abstinence compared to subjects who received 1.5 mg cytisinicline. The adverse events, or AEs, observed were mostly mild with transient headaches as the most commonly reported event. No severe or serious AEs were observed in the study.

In December 2017, we initiated a series of drug metabolism, drug-to-drug interaction, and transporter studies of cytisinicline and results from these studies were announced in June 2018. These studies demonstrated that cytisinicline has no clinically significant interaction with any of the hepatic enzymes commonly responsible for drug metabolism nor clinically significant interaction with drug transporters. This suggests that cytisinicline may be administered with other medications without the need to modify the dose of any co-administered medications. We will continue to evaluate any new FDA guidance on whether additional drug-to-drug interactions studies will be required prior to a future NDA filing.

We have met with the FDA and with other national regulatory authorities in Europe to identify the steps required for the approval of cytisinicline. We held an end of Phase 2 meeting with the FDA in May 2018 to review and receive guidance on our Phase 3 clinical program and overall development plans for cytisinicline to support an NDA. This review included submitted results from non-clinical studies, standard drug-to-drug interaction and reproductive/teratogenicity studies. Detailed plans for chronic toxicology, carcinogenicity studies, and additional clinical studies regarding renal impairment, QT interval prolongation, longer term exposure and adequate demonstration of safety and efficacy from our planned randomized, placebo-controlled, Phase 3 clinical trials were also discussed.

In 2018, Sopharma commercially launched a newly formulated cytisinicline tablet with improved shelf life in their territories. In May 2018, we initiated a study to evaluate the effect of food on the bioavailability of cytisinicline in volunteer smokers using this new formulation and data results were announced in September 2018. The study demonstrated similar bioavailability of cytisinicline in fed and fasted subjects. Cytisinicline was extensively absorbed after oral administration with maximum cytisinicline concentration levels observed in the blood within less than two hours with or without food. Total excretion levels of cytisinicline also remained equivalent in both the fed and fasted states, and the 3 mg dose using this new formulation of cytisinicline was well tolerated.

In the third quarter of 2018, the United States Adopted Names Council adopted cytisinicline as the non-proprietary, or generic, name for the substance also known as cytisine.

In December 2018, we announced that the FDA was in agreement with our Initial Pediatric Study Plan, specifically, providing a full waiver for evaluating cytisinicline in a pediatric population. The reasons for the full waiver were based on the low numbers of children smoking under the age of 12 and the logistical difficulties of recruiting treatment-seeking smokers in the adolescent age group. The



                                       23

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

agreed upon Initial Pediatric Study Plan is expected to be included as part of our future application for marketing approval of cytisinicline.

In March 2019, we initiated a clinical trial to assess the dose limiting AEs that would define the maximum tolerated dose, or MTD, for a single administered oral dose of cytisinicline. This study evaluated smokers who received one single dose of cytisinicline. The starting dosage of cytisinicline was 6 mg and was to be increased in separate groups of subjects for each escalated dose level until stopping criteria (based on the occurrence of dose-limiting AEs) were reached. A safety review after each dose level was performed by an independent Data Safety Monitor Committee, or DSMC, before escalation to the next dose level. Six dose levels were pre-planned with 21 mg cytisinicline as the highest dose level. When the MTD was not reached at 21 mg, the study was amended to evaluate doses up to 30 mg, as recommended by the DSMC. At this 30 mg dose, the stopping criteria of serious or severe AEs were still not met, but the DSMC recommended stopping the study since the frequency of gastrointestinal symptoms were approaching an MTD level. The results were reviewed with the FDA with agreement that further escalation beyond the single 30 mg dose was not required. This Phase-1 study was a requirement for our future NDA and marketing approval of cytisinicline. It fulfills an FDA requirement to evaluate potential safety issues in the event patients exceed a recommended single dose outside of a clinical trial setting. These results do not impact the intended dosing planned for future Phase 3 cytisinicline clinical trials which was informed by the Phase 2b ORCA-1 trial discussed below.

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 is the first in our ORCA (Ongoing Research of Cytisinicline for Addiction) 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 54% abstinence rate starting at week 4, compared to 16% 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). 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 AEs reported. The most commonly reported (>5%) 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. Based on the results of the ORCA-1 trial, we have 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 other doses and administrations studied in ORCA-1.

In November 2019, we held a type C meeting with the 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. We also discussed with the FDA timing for the submission of the 13-Week interim report from the second ongoing chronic toxicology study to support the longer treatment durations of 6- and 12-weeks in the Phase 3 clinical program. This interim chronic toxicology report was submitted in the second quarter of 2020 to the FDA in order to achieve our goal of initiating the Phase 3 program in the second half of 2020.



                                       24

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

Our planned Phase 3 trial, ORCA-2, is designed to evaluate the efficacy and safety of 3 mg TID of cytisinicline in smokers within the United States. The study plans to compare 3 mg TID of cytisinicline dosing versus placebo and will include behavioral support for all subjects. Co-primary endpoints of the study are an assessment of smoking abstinence during the last four weeks of 6-week and 12-week treatment periods, compared to similar placebo treatment periods. Secondary endpoints include smoking abstinence out to 24 weeks. Due to the ongoing COVID-19 pandemic, we are assessing the feasibility and required processes at each intended clinical site participating in the Phase 3 study, in order to initiate the Phase 3 study as planned in the second half of 2020. Study plans may be adjusted in response to COVID-19 public health control measures and in accordance with regulatory guidelines to ensure subject safety, data integrity and study continuity occurs.

In June 2020, we announced the topline results from the RAUORA trial, an independent investigator-sponsored Phase 3 clinical trial. The trial achieved statistical significance in showing that cytisinicline plus behavioral support was at least as effective as varenicline plus behavioral support at six months. In addition, the trial showed that cytisinicline resulted in significantly fewer reported adverse events when compared to varenicline. The final RAUORA trial results will be submitted for publication and are expected to be presented at SRNT Europe Annual Meeting in September 2020.

The RAUORA Phase 3 study was a non-inferiority clinical trial comparing cytisinicline to varenicline (Chantix®) 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 RAUORA trial was designed to evaluate the effectiveness, safety, and cost-effectiveness of cytisinicline compared to varenicline as a smoking cessation aid. The study compared cytisinicline administered on a schedule of 25 days of downward dosing titration followed by twice-daily dosing for a total of 12 weeks with varenicline administered on a schedule of seven days of upward 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. In total, 1,105 M?ori or wh?nau expressed 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.

We are also considering potential clinical studies in users of e-cigarettes. This is an important area of focus given the vaping epidemic and the number of vaping-related lung illnesses that were reported in 2019. The number of e-cigarette users continues to grow and, according to data published in the Annals of Internal Medicine in 2018, there are a reported 10.8 million e-cigarette users in the United States alone. The National Institute on Drug Abuse, or NIDA, a division of the NIH, has tobacco/nicotine and vaping on their list of Drugs of Abuse. While e-cigarettes have been viewed as generally safer than combustible cigarettes, the long-term safety of e-cigarettes is still unproven and may sustain nicotine addiction. Given the mechanism of action of cytisinicline, we believe it could be used to help address nicotine addiction for e-cigarette users. We have engaged FreeMind Group to assist in conducting a strategic assessment and in securing non-dilutive funding to evaluate cytisinicline in reduction or cessation of vaping and or e-cigarettes.

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 $6.2 million for the six months ended June 30, 2020. As of June 30, 2020, we had an accumulated deficit of $51.9 million, cash and cash equivalents balance of $12.1 million and a positive working capital balance of $10.8 million. During the six months ended June 30, 2020, net cash used in operations was $6.7 million.

Substantial doubt exists as to our ability to continue as a going concern. Our ability to continue as a going concern is uncertain 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 12 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.



                                       25

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

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.

Reverse Stock Split

On July 29, 2020, we filed a certificate of amendment to our Second Amended and Restated Certificate of Incorporation, as amended, and effected as of July 31, 2020 a 1-for-20 reverse stock split of our issued and outstanding shares of common stock. As a result of the reverse stock split, each 20 shares of the outstanding common stock were combined into one share of common stock without any change to the par value per share. The reverse stock split did not affect the number of authorized shares of common stock which remains at 150,000,000. The reverse stock split was approved by our board of directors and stockholders and is intended to allow us to regain compliance with the NASDAQ's continued listing criteria related to the Minimum Bid Price Rule. However, there can be no assurance that we will regain compliance until a written confirmation from NASDAQ has been issued.

Unless otherwise noted, impacted amounts and share information included in the financial statements and notes thereto have been retroactively adjusted for the stock split as if such stock split occurred on the first day of the first period presented. Certain amounts in the notes to the financial statements may be slightly different than previously reported due to rounding of fractional shares as a result of the reverse stock split.

License 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, AD, or 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, the trademark Tabex 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 Tabex branded 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



                                       26

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

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, 2020, 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 research and development 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 research and development 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 its 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, or G&A, 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.

The increases in the 2020 periods as compared to the 2019 periods were primarily due to additional market research and public relations activities, this was partially offset by lower travel costs as a result of travel restrictions across the U.S and other countries during the COVID-19 pandemic.

Liquidity and Capital Resources

We have incurred an accumulated deficit of $51.9 million through June 30, 2020 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, 2020, we had a cash and cash equivalents balance of $12.1 million and a positive working capital balance of $10.8 million.

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 uncertain 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 market generally due to the COVID-19 pandemic may make it challenging to raise additional capital on favorable terms, if at all. We have, thus far, financed our operations through payments from former collaborators and equity 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 12 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.

Lincoln Park Capital Equity Line

On September 14, 2017 we and Lincoln Park Capital Fund, LLC, or LPC, entered into a share and unit purchase agreement, which was amended on March 12, 2020, or the Purchase Agreement, pursuant to which we have the right to sell to LPC up to $11.0 million in shares of our common stock, par value $0.001 per share, subject to certain limitations and conditions set forth in the Purchase Agreement. On May 22, 2018 we obtained the requisite stockholder authorization to sell shares of our common stock to LPC in excess of 20% of our outstanding shares of common stock (as of the date we entered into the Purchase Agreement) in order to be able to sell to LPC the full amount remaining under the Purchase Agreement.

Pursuant to the Purchase Agreement, LPC initially purchased 1,644 of our units, or the Units, at a purchase price of $608.00 per unit, with each Unit consisting of (a) one share of our common stock and (b) one warrant to purchase one-quarter of a share of common stock at an exercise price of $699.20 per share, or Warrant. Each Warrant became exercisable six months following the issuance date



                                       28

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

until the date that is five years and six months after the issuance date and is subject to customary adjustments. The Warrants were issued only as part of the Units in the initial purchase of $1.0 million and no warrants shall be issued in connection with any other purchases of common stock under the Purchase Agreement.

After the initial purchase, if our stock price is above $1.00, as often as every other business day over the 54-month term of the Purchase Agreement, and up to an aggregate amount of an additional $10.0 million (subject to certain limitations) of shares of common stock, we have the right, from time to time, in our sole discretion and subject to certain conditions to direct LPC to purchase up to 7,500 shares of common stock. The purchase price of shares of common stock pursuant to the Purchase Agreement will be based on prevailing market prices of common stock at the time of sales without any fixed discount, and we will control the timing and amount of any sales of common stock to LPC. As consideration for entering into the Purchase Agreement, we issued to LPC 617 shares of common stock in September 2017 and, in connection with the amendment of the Purchase Agreement in March 2020, we paid to LPC $0.1 million as an expense reimbursement. The consideration of 617 shares of our common stock were fair valued based on the closing price of our common stock as at the transaction date and recognized as part of offering expenses.

During the three and six months ended June 30, 2020, we offered and sold zero shares of our common stock pursuant to the Purchase Agreement with LPC. Since entry into the Purchase Agreement, from September 14, 2017 through June 30, 2020, we offered and sold an aggregate of 27,868 shares of our common stock, including the 1,644 shares that were part of the initial purchase of Units. These aggregate sales resulted in gross proceeds to us of approximately $4.4 million and offering expenses of $0.5 million. As of June 30, 2020, shares of our common stock having an aggregate value of approximately $6.6 million remained available for sale under this offering program.

At The Market Offering Agreement with H.C. Wainwright & Co., LLC

On June 7, 2019, we entered into an At The Market Offering Agreement, or the Offering Agreement, with H.C. Wainwright & Co., LLC, as agent, or H.C. Wainwright, pursuant to which we may offer and sell, from time to time and at our election, through H.C. Wainwright, shares of our common stock, par value $0.001 per share, having an aggregate offering price of up to $6.0 million.

Pursuant to the Offering Agreement, H.C. Wainwright may sell the shares our common stock by any method permitted by law deemed to be an "at the market offering" as defined in Rule 415 of the Securities Act, including sales made by means of ordinary brokers' transactions, including on The Nasdaq Capital Market, at market prices or as otherwise agreed with H.C. Wainwright. H.C. Wainwright will use commercially reasonable efforts consistent with its normal trading and sales practices to sell the shares of common stock from time to time, based upon instructions from us, including any price or size limits or other customary parameters or conditions we may impose.

We will pay H.C. Wainwright a commission rate equal to 3.0% of the aggregate gross proceeds from each sale of shares of common stock and have agreed to reimburse H.C. Wainwright for certain specified expenses in connection with entering into the Offering Agreement.

From June 7, 2019 to August 4, 2020, we did not offer any shares of our common stock for sale pursuant to the Offering Agreement. As of May 13, 2020, shares of our common stock having an aggregate value of approximately $6.0 million remained available for sale under the Offering Agreement.

Warrant Exercise Agreement

On May 30, 2019, we entered into a Warrant Exercise Agreement, or the Exercise Agreement, with a Shareholder of our common stock, or the shareholder. Pursuant to the Exercise Agreement, the shareholder exercised (i) outstanding warrants to purchase 13,515 shares of our common stock, par value $0.001 per share, with an exercise price of $62.89 per share issued as part of the October 2018 financing and (ii) outstanding warrants to purchase 41,875 shares of our common stock with an exercise price of $80.00 per share issued as part of the June 2018 financing, for aggregate exercise proceeds to us of approximately $4.2 million, or, collectively, the Warrant Exercise.

As an inducement for the Warrant Exercise, we agreed to issue to the shareholder a new warrant, exercisable for six years, to purchase up to 60,000 shares of our common stock at an exercise price of $90.00 per share. We also agreed to file a registration statement covering the resale of the New Warrant Shares. The New Warrant and New Warrant Shares were offered to the shareholder in reliance upon the exemption provided by Rule 506 of Regulation D and Section 4(a)(2) of the Securities Act of 1933.

Under ASC 260, the fair value of the new warrants of $3.9 million was recognized into accumulated deficit.

December 2019 Public Offering





                                       29

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

On December 17, 2019, we completed an underwritten registered public offering, pursuant to which we sold, 478,875 Class A Units at a price per unit of $12.00 and 6,256 Class B Units at a price per unit of $999.60.

Each Class A Unit consisted of one share of our common stock and a warrant to purchase one share of common stock.

Each Class B Unit consisted of one share of Series B Convertible Preferred Stock, par value $0.001 per share, convertible at any time at the holder's option into approximately 83 shares of common stock, and warrants to purchase approximately 83 shares of common stock.

Each warrant was immediately exercisable, expires on the five year anniversary of the date of issuance and is exercisable at a price per share of common stock of $6.60, subject to adjustment in the event of subsequent equity sales of common stock or securities convertible into common stock for an exercise price per share less than the exercise price per share of the warrants then in effect, provided, however, that the exercise price of the warrants cannot be reduced to an amount less than $1.20 per share of common stock. Additionally, subject to certain exceptions, if, after December 17, 2019, (i) the volume weighted average price of the common stock for each of 30 consecutive trading days, or the 2019 Measurement Period, which 2019 Measurement Period commences on the closing date, exceeds 300% of the exercise price (subject to adjustments for stock splits, recapitalizations, stock dividends and similar transactions), (ii) the average daily trading volume for such 2019 Measurement Period exceeds $500,000 per trading day and (iii) certain other equity conditions are met, and subject to a beneficial ownership limitation, then the Company may call for cancellation of all or any portion of the warrants then outstanding.

The Class A Units and Class B Units were not certificated and the shares of common stock, Series B Convertible Preferred Stock and warrants comprising such Units were immediately separable and were issued separately in the public offering. The Class A and B Units were offered by us pursuant to the registration statement on Form S-1 (File No. 333-234530), and each amendment thereto, which was initially filed with the SEC on November 6, 2019 and declared effective by the SEC on December 17, 2019.

In addition, pursuant to the Underwriting Agreement we entered into with Ladenburg Thalmann & Co. Inc., or Ladenburg, on December 17, 2019, we granted Ladenburg a 45 day option, or the 2019 Overallotment Option, to purchase up to 150,000 additional shares of common stock and/or warrants to purchase up to 150,000 shares of common stock solely to cover over-allotments. The 2019 Overallotment Option was exercised in full on December 17, 2019.

The public offering raised total gross proceeds of $13.8 million and after deducting $1.5 million in underwriting discounts and commissions and offering expenses, we received net proceeds of $12.3 million.

The underwriting discounts and commissions and offering expenses have been charged against the gross proceeds.

As of June 30, 2020, all 6,256 shares of the Series B Convertible Preferred Stock had been converted into 521,124 shares of common stock, and no shares of the Series B Convertible Preferred Stock remained outstanding.

April 2020 Private Placement

On April 27, 2020 and April 28, 2020, we entered into subscription agreements with certain accredited investors pursuant to which we sold to the purchasers in a private placement approximately 280,782 units, or Units, each consisting of (i) one share of common stock, and (ii) a warrant to purchase 0.75 shares of common stock at an offering price of $6.60 per Unit, for aggregate gross proceeds of approximately $1.9 million. Paulson Investment Company, LLC, or the Broker, acted as the exclusive placement agent for the offering and, pursuant to the placement agent agreement between us and the Broker, received a cash commission equal to 9% of the gross proceeds from the sale of the Units and was issued a five (5) year warrant upon substantially similar terms as the investor warrants to purchase 25,270 shares of common stock at an initial exercise price of $7.59 per share. The net proceeds to us, after deducting Broker expenses and commissions and offering expenses was approximately $1.6 million.



                                       30

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

Each warrant is exercisable beginning on October 27, 2020, the six-month anniversary of the initial closing date of the offering, through April 27, 2025, which is the five year anniversary of the initial closing date of the offering. The warrants issued pursuant to subscription agreements executed on April 27, 2020 are exercisable at a price per share of common stock of $7.24, subject to adjustment, and the warrants issued pursuant to subscription agreements executed on April 28, 2020 are exercisable at a price per share of common stock of $7.32, subject to adjustment. Additionally, subject to certain exceptions, if, after the initial exercise date, (i) the volume weighted average price of the common stock for each of 30 consecutive trading days, or the Measurement Period, which, Measurement Period commences on the closing date, exceeds 300% of the exercise price (subject to adjustments for stock splits, recapitalizations, stock dividends and similar transactions), (ii) the average daily trading volume for such Measurement Period exceeds $500,000 per trading day and (iii) certain other equity conditions are met, and subject to a beneficial ownership limitation, then we may call for cancellation of all or any portion of the warrants then outstanding.

July 2020 Registered Direct Offering

On July 1, 2020, we completed a registered direct offering, pursuant to which we sold 731,707 shares of our common stock at a price of $8.20 per share. We paid Lake Street Capital Markets, LLC, the exclusive placement agent for the offering, and Ladenburg Thalmann & Co. Inc., our advisor, a cash fee equal to an aggregate of 8% of the gross proceeds generated from the sale of the common stock and also reimbursed the placement agent for certain of its expenses.

The registered direct offering raised total gross proceeds of $6.0 million, and after deducting approximately $0.5 million in placement agent fees and offering expenses, we received net proceeds of approximately $5.5 million.

August 2020 Public Offering

On August 3, 2020, we entered into an underwritten public offering of our securities, or the Public Offering, pursuant to which we will sell an aggregate of (a) 569,043 shares of our common stock, including 92,856 shares subject to the underwriter's option to purchase additional shares, or the Shares, and (b) pre-funded warrants to purchase 142,857 shares of our common stock, or the Pre-Funded Warrants, to the underwriter. The Shares will be sold at the public offering price of $10.50 per share. The Pre-Funded Warrants will be sold at a public offering price of $10.499 per Pre-Funded Warrant, which represents the per share public offering price for the Shares less a $0.001 per share exercise price for each such Pre-Funded Warrant.

The Pre-Funded Warrants are exercisable at any time after the date of issuance. A holder of Pre-Funded Warrants may not exercise the warrant if the holder, together with its affiliates, would beneficially own more than 9.99% of the number of shares of common stock outstanding immediately after giving effect to such exercise. A holder of Pre-Funded Warrants may increase or decrease this percentage, but not in excess of 19.99%, by providing at least 61 days' prior notice to us.

We estimate that total gross proceeds from the Public Offering will be approximately $7.5 million and after deducting approximately $0.7 million in underwriting discounts and commissions and offering expenses, we estimate net proceeds to be approximately $6.8 million. The underwriting discounts and commissions and offering expenses will be charged against the gross proceeds. We expect the Public Offering to close on or about August 6, 2020, subject to the satisfaction of customary closing conditions.

Cash Flows

Cash Used in Operating Activities

For the six months ended June 30, 2020, net cash used in operating activities was $6.7 million compared to $8.7 million for the six months ended June 30, 2019. The decrease in cash used in operations in the 2020 period as compared to the 2019 period was primarily attributable to decrease in research and development expenses related to our ORCA-1 trial.

Cash Provided in Financing Activities

For the six months ended June 30, 2020, net cash provided by financing activities was $2.1 million compared to $4.6 million for the six months ended June 30, 2019. Net cash provided by financing activities in the six months ended June 30, 2020 relates to proceeds received from the April 2020 Private Placement and warrant exercises. Net cash provided by financing activities in the six months ended June 30, 2019 relates to proceeds received from warrant exercises and from our purchase agreement with LPC.

Cash Used in Investing Activities

Net cash used in investing activities for the six months ended June 30, 2020 was $14,000 compared to net cash provided by investing activities of $5.0 million for the six months ended June 30, 2019. Net cash used in investing activities in the six months ended June 30, 2020 relates primarily to the purchase of equipment. Net cash provided by investing activities for six months ended June 30, 2019 relates primarily to transactions involving marketable securities in the normal course of business.



                                       31

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

Off-Balance Sheet Arrangements

We did not have any off-balance sheet financing arrangements as of June 30, 2020.

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, 2019, as filed with the SEC on March 13, 2020. 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 2019 Form 10-K. For more information regarding our current contingencies and commitments, see note 7 to the financial statements included above.

Material Changes in Financial Condition





                                       June 30,       December 31,
                   (in thousands)        2020             2019
                   Total Assets        $  16,458     $       21,078
                   Total Liabilities       1,920              3,028
                   Total Equity           14,538             18,050



The decrease in assets at June 30, 2020 compared to December 31, 2019 is attributable to a decrease in cash, cash equivalents and short-term investments as these assets have been used to fund operations. The decrease in liabilities at June 30, 2020 as compared to December 31, 2019 was primarily due to lower employee bonus accrual in accrued compensation and lower trades payables as our ORCA-1 trial, a Phase 2b optimization study that was initiated in October 2018 and was completed in June 2019.

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, 2019 in our Annual Report on Form 10-K filed with the SEC, on March 13, 2020. Since December 31, 2019, 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 2020, 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.
