ORCA-2 Designed to Assess the Efficacy and Safety of 3 mg Cytisinicline Three Times Daily Dosing Compared to Placebo in Adult Smokers in the United States

SEATTLE, WA and VANCOUVER, BC / ACCESSWIRE / June 29, 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 that the Phase 3 ORCA-2 trial of cytisinicline has reached its enrollment target of 750 adult smokers. The ORCA-2 trial sites are no longer enrolling new subjects, however those currently in screening will be allowed to participate provided they meet entry criteria.

The ORCA-2 trial is designed to evaluate the smoking cessation effectiveness, safety, and tolerability of 3 mg cytisinicline taken three times daily (TID) for either 6 or 12 weeks and will be compared with placebo. Subjects in the trial will be monitored through 24 weeks post randomization and will receive standard behavioral support for the duration of the trial. More than 750 participants have been randomized across the 17 clinical sites in the United States.

"There remain more than 50 million Americans addicted to some form of tobacco, including over 34 million cigarette smokers in the United States alone and completion of ORCA-2 enrollment is a critical milestone in advancing cytisinicline, a potential new treatment that could make a major impact on the global public health smoking epidemic," stated John Bencich, Chief Executive Officer of Achieve. "We extend our gratitude to the participants in the ORCA-2 trial and wish them much success in their quitting journey, as well as to our clinical trial sites for all of their hard work."

Topline ORCA-2 data results are expected to be reported within the first half of 2022. The primary outcome measure of success in the ORCA-2 trial is biochemically verified continuous abstinence during the last four weeks of treatment in either the 6 or 12-week cytisinicline treatment arms as compared with placebo. Each treatment arm will be compared independently to the placebo arm, and the trial will be declared successful if either or both cytisinicline treatment arms show a statistical benefit as compared with placebo. Secondary outcome measures include continued abstinence rates to 6 months after study randomization. Previously, in the Phase 2b ORCA-1 trial of 254 smokers, subjects treated with the 3 mg TID treatment arm of cytisinicline were 5-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).

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 drug product being developed for treatment of nicotine addiction and has not been approved by the FDA for any indication in the United States. For more information on cytisinicline and the ORCA-2 study, visit www.achievelifesciences.com.
