SEATTLE, WA and VANCOUVER, BC / ACCESSWIRE / May 13, 2021 / 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 2021 financial results and provided an update on the cytisinicline clinical development program.

Recent Events & Highlights

• Provided update on the Phase 3 ORCA-2 clinical trial evaluating the efficacy and safety of 3.0 mg cytisinicline dosed 3 times daily compared to placebo in 750 adult smokers at 17 clinical sites in the United States
• Published Phase 2b ORCA-1 safety, efficacy, and compliance results in Nicotine and Tobacco Research
• Announced the appointment of Dr. Bridget Martell and Dr. Cindy Jacobs to Achieve's Board of Directors
• Published RAUORA Head-to-Head Non-Inferiority Clinical Trial Comparing Cytisinicline and Chantix® (varenicline) in Addiction

"In the first quarter, we've seen great interest and increased momentum in the ORCA-2 trial and look forward to completing enrollment by the middle of the year," commented John Bencich, Chief Executive Officer of Achieve. "We will continue to focus our efforts on execution of the Phase 3, ensuring all required NDA-enabling activities remain on track, and furthering our discussions with potential strategic partners to prepare for cytisinicline commercialization."

Phase 3 ORCA-2 Trial
The Phase 3 ORCA-2 trial continues to enroll at 17 clinical sites in the United States. Approximately 750 adult smokers will be randomized to one of three study arms to determine the efficacy and safety of cytisinicline administered for either six or twelve weeks, compared to placebo. The primary endpoint is biochemically verified continuous abstinence during the last four weeks of treatment in the six and twelve-week cytisinicline treatment arms compared to 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. The trial is expected to complete enrollment by the middle of 2021.

ORCA-1 Results Published in Nicotine and Tobacco Research
Results from the Phase 2b ORCA-1 trial were published in the scientific journal Nicotine and Tobacco Research. ORCA-1 evaluated the efficacy and safety of cytisinicline across various dosing and administration schedules in 254 smokers in the United States. The publication reported that subjects treated with cytisinicline, regardless of dose or schedule, had statistically significantly higher (p<0.001) end of treatment abstinence rates compared to those treated with placebo. Participants in the 3.0 mg cytisinicline 3 times daily (TID) arm, were five times more likely to quit smoking than those in the placebo arm (OR of 5.04, 95% CI: 1.42, 22.32, p<0.001). Cytisinicline was well-tolerated with no serious or severe adverse events (AEs) reported.

Appointment of Drs. Martell and Jacobs to Board of Directors
Achieve announced the appointment of two new members to Achieve's Board of Directors, Dr. Bridget Martell and Dr. Cindy Jacobs. Dr. Martell is board certified in both Internal and Addiction Medicine and is an experienced executive leader in the pharmaceutical industry. Dr. Jacobs serves as Achieve's President and Chief Medical Officer, and in addition to her Board of Directors duties, will continue in her current role leading Achieve's regulatory and clinical development efforts for cytisinicline.

RAUORA Trial Results Published in Addiction
Results from the Phase 3 RAUORA trial were published in the scientific journal Addiction. RAUORA evaluated the effectiveness and safety of cytisinicline compared to Chantix® (varenicline) as a smoking cessation aid in 679 indigenous New Zealanders (Māori). The published results indicate that 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), and a 55% improvement in quit rates at six months in favor of cytisinicline when compared to Chantix. A Bayesian analysis of the primary efficacy outcome is ongoing. Additionally, statistically significant fewer overall AEs were reported in cytisinicline-treated subjects (Relative Risk 0.56, 95% CI 0.49 to 0.65, p<0.001) including a significantly lower rate of nausea when compared to subjects on Chantix.

About Achieve and Cytisinicline
Tobacco use is currently the leading cause of preventable death that is responsible for more than eight million deaths worldwide and nearly half a million deaths in the United States annually.^1,2 More than 87% of lung cancer deaths, 61% of all pulmonary disease deaths, and 32% of all deaths from coronary heart disease are attributable to smoking and exposure to secondhand smoke.² 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. Cytisinicline is an investigational product candidate being developed for treatment of nicotine addiction and has not been approved by the Food and Drug Administration for any indication in the United States.
