SEATTLE, Wash and VANCOUVER, British Columbia, August 6, 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 second quarter 2020 financial results and provided an update on the cytisinicline clinical development program.

Recent Highlights

“It has been a busy an exciting quarter with new evidence further reinforcing our belief that cytisinicline has the potential to provide a more tolerable cessation treatment to millions of smokers who want to quit,” commented Rick Stewart, Chairman and Chief Executive Officer of Achieve. We continue to focus our efforts on initiation of the 750 patient Phase 3 ORCA-2 trial in the second-half of 2020, subject to the ability to conduct the trial safely in light of the COVID-19 pandemic.”

Successful RAUORA Head-to-Head vs Chantix® Study Results  

Achieve announced the successful topline results from the New Zealand RAUORA Phase 3 non-inferiority clinical trial comparing cytisinicline to varenicline (Chantix) in Māori (indigenous New Zealanders) and whānau (family) of Māori. 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 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 final RAUORA trial results have been submitted for presentation at The Society for Research on Nicotine and Tobacco Europe (SRNT-E) Annual Meeting in September 2020.

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.
