Achieve Life Sciences Shareholder Letter – October 2020

October 22, 2020

Dear Fellow Shareholders,

We hope this letter finds you and your families safe and healthy. Given that we continue to live in unprecedented times, faced with uncertainty and unique challenges, John and I thought it was appropriate to reach out with an update on the company’s progress.

Achieve remains committed to prioritizing the health and safety of our patients, health care providers, and employees. Like many of you, we have adjusted how we conduct business. Our teams continue to work remotely, we have restricted all non-essential travel, and we have implemented numerous safeguards for employees and stakeholders. This commitment extends to participants in our upcoming trials to mitigate against the potential impact of COVID-19. While this is not business as usual, we continue to make excellent progress advancing cytisinicline towards U.S. market approval.

On the corporate development front, we recently announced management changes that included internal promotions of two key executives. These changes have been planned for a long time and were expedited in part by the pandemic, which has restricted international travel for Rick Stewart and Dr. Anthony Clarke, co-founders of Achieve, who are both based in the United Kingdom.

The appointment of John Bencich as Chief Executive Officer and Dr. Cindy Jacobs as President and Chief Medical Officer reflects their contributions to the success of the company thus far. Rick Stewart will continue to serve as the Executive Chairman of the Board of Directors. Additionally, Rick will continue providing his expertise and leadership on strategic initiatives for the company, such as potential commercial partnering and registration of cytisinicline in European markets.

Over the last three years as Achieve’s Chief Financial and Operating Officer, John has led the financing activities which provided the capital to complete the successful Phase 2 ORCA-1 trial last year, and more recently, the funding to allow us to initiate the Phase 3 ORCA-2 trial. John has consistently demonstrated his leadership capabilities across all aspects of the business and has been instrumental in ensuring that Achieve continues to execute on its key objectives.

Under her stewardship, Dr. Cindy Jacobs has led the clinical development team at Achieve and has been responsible for the successful ORCA-1 Phase 2b trial and the planning and execution of the ORCA-2 Phase 3 trial that recently commenced.

While our leadership has realigned, our management team remains steadfast in our mission and in our conviction that cytisinicline has great promise to change the lives of millions of smokers.

In this regard, we are pleased to have recently announced the start of the Phase 3 ORCA-2 trial that we expect will enroll 750 smokers at 15 clinical trial locations throughout the United States. ORCA-2 is the first randomized, double-blind Phase 3 trial evaluating a new therapy for smoking cessation in over a decade. ORCA-2 is designed to evaluate the efficacy and safety of 3 mg cytisinicline given three times daily for 6 and 12-weeks compared to placebo. Importantly, the study will be considered successful if either or both of the arms show an efficacy benefit.

As a reminder, the Phase 2b ORCA-1 trial that we conducted in 250 U.S. smokers showed robust efficacy and a well-tolerated safety profile for cytisinicline, providing important insights to help us to optimize the design of the Phase 3 trial. In ORCA-2, we will evaluate the higher 3 mg dose for a longer treatment duration and utilize the simplified three times daily dosing regimen. We believe these modifications could lead to potentially increased quit rates and more durable efficacy results.

The confidence that we have in cytisinicline’s ability to help smokers quit comes not only from our own studies but from numerous clinical trials that have evaluated more than 10,000 smokers and have been conducted by external experts in the field of smoking cessation.

Most recently, the results of the “RAUORA” trial that compared cytisinicline to Chantix®, the market leader in smoking cessation, were presented at the Society for Research on Nicotine and Tobacco (SRNT) Annual European Meeting. This was the first-ever head-to-head study comparing these two treatments and enrolled a total of 679 smokers. The trial met its primary endpoint of showing that cytisinicline was non-inferior to Chantix and also showed a trend towards superiority for cytisinicline. Smokers who received cytisinicline were one- and one-half times more likely to have quit smoking at six months compared to those who received Chantix.  Importantly, subjects on cytisinicline experienced significantly fewer side effects, including significantly less nausea than those subjects treated with Chantix.

Data were also presented at this meeting that may help to explain why the mechanism of action is directly implicated in the differentiated side effect profiles of these two smoking cessation medications. Research from the University of Cambridge Department of Biochemistry elucidated the potential role of the 5-HT3 receptor activity in the development of Chantix side effects. By comparison to cytisinicline, this study showed that Chantix has a 2000-greater fold binding affinity to the 5-HT3 receptor, which is believed to be the cause of increased rates of nausea and vomiting that smokers can experience while on Chantix.

It is widely documented that nicotine is one of the most addictive substances on the planet. Quitting smoking successfully often takes multiple attempts, which is why a new therapy with improved safety and tolerability is urgently needed. We believe and expect to confirm in our Phase 3 trials that cytisinicline can offer smokers a safe and effective new treatment and a renewed hope in their ability to quit.

As we look to the future, our primary focus is enrollment and execution of our Phase 3 program in smoking cessation. We do, however, continue to explore opportunities for expansion into new therapeutic indications, digital health technologies, and audiences who may benefit from cytisinicline, specifically, users of vapes or e-cigarettes.

The use of e-cigarettes continues to grow, with most recent reports indicating nearly 14 million adult users in the United States alone.  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 they intend to quit vaping within the next 3 to 12 months. Of those who intended to quit even sooner, within the next three months, more than half stated they would be extremely likely to try a new prescription product to help them do so.

In partnership with leading smoking cessation and nicotine addiction experts, we have completed the development of a Phase 2 ORCA-V1 trial protocol to evaluate cytisinicline in this rapidly growing population of e-cigarette users. We are currently pursuing non-dilutive funding sources to help support this initiative. We believe that cytisinicline could be the first prescription drug to offer a new option for vape and e-cigarette users who are ready to quit their nicotine addiction for good.

Regarding our capitalization, our current funding and cash position are strong. We had approximately $12.2 million as of June 30, 2020, and secured an additional $14.8 million in proceeds, after commissions and offering expenses, from equity financings and warrant exercises during the third quarter. To that end, we recently terminated our At the Market (ATM) Offering Agreement with H.C. Wainwright & Co., LLC, as we did not expect to utilize the facility going forward. The facility was terminated unused with no shares issued or sold.

In closing, thank you for your interest and continued support of Achieve. This is an exciting time for the company as we embark on our Phase 3 program that has the potential to impact the health and well-being of millions of smokers. We will continue to remain focused on our mission and appreciate your support as we make the important transition to Phase 3 development.
