Achieve Reports Financial Results for First Quarter 2020 and Provides Update on Cytisinicline Development Program  

SEATTLE, Wash and VANCOUVER, British Columbia, May 14, 2020 -- Achieve Life Sciences, Inc. (Nasdaq: ACHV), a clinical-stage pharmaceutical company committed to the global development and commercialization of cytisinicline for smoking cessation and nicotine addiction, today announced first quarter 2020 financial results and provided an update on the cytisinicline clinical development program.

Recent Highlights

“The COVID-19 pandemic has revealed an increased risk for smokers due to the known relationship between smoking and respiratory illnesses and we see an even greater need to do all that we can to help them quit,” commented Rick Stewart, Chairman and Chief Executive Officer of Achieve. “We expect to initiate the 750 patient Phase 3 ORCA-2 trial in the second-half of 2020, subject to financing and the ability to conduct the trial safely in light of the COVID-19 pandemic.”

Completed FDA Submission  

In preparation for initiation of the Phase 3 ORCA-2 clinical trial of cytisinicline, the Company has now submitted to FDA all requested non-clinical data to allow 6 and 12 weeks of cytisinicline treatment in the Phase 3 trials. No new safety or toxicology signals were observed in the non-clinical data evaluating either 13 or 26 weeks of cytisinicline treatment.

Closed private placement financing for gross proceeds of $1.9 million

In April 2020, Achieve announced it entered into definitive agreements for a private placement of its securities for gross proceeds of approximately $1.9 million, prior to deducting placement agent commissions and estimated offering expenses. The Company intends to use the proceeds to fund clinical research and development, and for general working capital.

Additional ORCA-1 Results at SRNT Annual Conference  

An oral presentation featuring new ORCA-1 Phase 2b trial analyses was presented at the SRNT Annual Meeting in March 2020. In addition to previously reported data indicating a statistically significant improvement in quit rates, new analyses demonstrate cytisinicline biochemical efficacy via measurement of serum cotinine as well as the previous carbon monoxide efficacy. Additionally, further analyses confirm that cytisinicline benefit was observed across all clinical sites, baseline

characteristics, and attributes. Thus, regardless of trial site location, patient demographics, smoking history, or prior treatments, all subjects treated with cytisinicline showed similar smoking cessation benefit.   

Agreement with the FreeMind Group to secure non-dilutive financing for vaping trials

In the first quarter of 2020, Achieve retained the FreeMind Group, an international consulting firm dedicated to assisting life science organizations secure non-dilutive funding. Achieve and FreeMind are conducting a strategic assessment of potential non-dilutive funding opportunities from various public and private sources, followed by anticipated grant production and submission, to further the clinical development of cytisinicline in vaping or e-cigarette cessation.

Financial Results

As of March 31, 2020, the company’s cash, cash equivalents, and restricted cash was $12.2 million. Total operating expenses for the quarter ended March 31, 2020 were $3.4 million. Total net loss for the quarter ended March 31, 2020 was $3.3 million.

As of March 14, 2020, Achieve had 37,515,408 shares outstanding.

About Achieve and Cytisinicline
Tobacco use is currently the leading cause of preventable death and is responsible for more than eight million deaths annually worldwide¹. It is estimated that 28.7% of cancer deaths in the U.S. are attributable to cigarette smoking². Achieve’s focus is to address the global smoking health and nicotine addiction epidemic through the development and commercialization of cytisinicline.

Cytisinicline is a plant-based alkaloid with a high binding affinity to the nicotinic acetylcholine receptor. It is believed to aid in smoking cessation by interacting with nicotine receptors in the brain by reducing the severity of nicotine withdrawal symptoms and by reducing the reward and satisfaction associated with smoking.

As an approved, branded product in Central and Eastern Europe for more than two decades, it is estimated that over 20 million people have used cytisinicline to help combat nicotine addiction.
