SEATTLE, Wash and VANCOUVER, British Columbia, July 31, 2020 — Achieve Life Sciences, Inc. (NASDAQ: ACHV), a clinical-stage pharmaceutical company committed to the global development and commercialization of cytisinicline for smoking cessation, today announced that the United States Patent and Trademark Office has granted Achieve a patent (US 2020/0172544 A1) on novel analogs of cytisinicline, a process for their preparation, and their use in the prevention or treatment of CNS and addictive disorders.

Cytisinicline is a selective partial agonist of nicotinic acetylcholine receptors (nAChRs), which underlies its activity in nicotine addiction. nACHRs are more broadly involved in a range of physiological functions, such as cognitive function, learning and memory, emotion and control of movement. The newly patented analogs provide the opportunity for selective targeting of nAChRs in the brain in order to treat a number of conditions, such as Alzheimer’s disease, depression, anxiety, schizophrenia, epilepsy, Parkinson’s disease and addiction.

“While smoking cessation and nicotine addiction continue to be our primary focus, it is critically important that we continue to expand our intellectual property portfolio through patent extensions and future potential indications of cytisinicline,” stated Rick Stewart, Chairman and Chief Executive Officer of Achieve.

About Achieve and Cytisinicline
Tobacco use is currently the leading cause of preventable death and is responsible for more than eight million deaths annually worldwide[1]. It is estimated that 28.7% of cancer deaths in the U.S. are attributable to cigarette smoking[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.

As an approved, branded product in Central and Eastern Europe for more than two decades, it is estimated
