Achieve Reports Financial Results for First Quarter 2019 and Provides Cytisinicline Clinical Development Update

SEATTLE and VANCOUVER, British Columbia, May 15, 2019 /CNW/ -- Achieve Life Sciences, Inc. (Nasdaq: ACHV), a clinical-stage pharmaceutical company committed to the global development and commercialization of cytisinicline for smoking cessation, today provided an update on the cytisinicline clinical development program and announced first quarter 2019 financial results.

ORCA-1 Trial Status
Achieve's 254-subject Phase 2b ORCA-1 trial of cytisinicline in U.S. smokers completed enrollment in February. The Company announced recently that the last study visit for the last subject enrolled in the ORCA-1 trial has occurred. The trial is evaluating cytisinicline in both the 1.5 mg and 3.0 mg doses on a declining titration schedule as well as three times daily dosing, both over 25 days. The primary efficacy endpoint is reduction in the number of cigarettes smoked during treatment with secondary analyses to be conducted on smoking cessation rates, safety, and compliance. ORCA-1 topline efficacy and safety data are expected to be announced by the end of the second quarter.

Maximum Tolerated Dose (MTD) Trial Extension
Achieve recently initiated a trial to assess the MTD for a single administered oral dose of cytisinicline in smokers. The starting dosage of cytisinicline was 6 mg and is increased in separate groups of subjects for each escalated dose level until stopping criteria, based on the occurrence of dose-limiting adverse events, are reached. To date, 21 mg cytisinicline has been evaluated without evidence of dose limiting toxicity. The trial's Data Safety Monitoring Committee has recommended a protocol amendment to evaluate additional higher doses of cytisinicline.

Rick Stewart, Chairman and Chief Executive Officer of Achieve Life Sciences commented, "With the results of the ORCA-1 trial expected by the end of the second quarter, we are rapidly approaching another critical milestone for the cytisinicline development program. Importantly, as confirmed by the tolerability of high dose levels in our MTD study, we believe cytisinicline may offer a differentiated and new treatment option for the millions of people who are battling nicotine addiction."

Financial Results
As of March 31, 2019, the company's cash, cash equivalents, short-term investments and restricted cash were $9.7 million. Each of total operating expenses and net loss for the first quarter of 2019 were $5.9 million.

As of May 15, 2019 Achieve had 6,865,950 shares outstanding.

About Achieve and Cytisinicline
Tobacco use is currently the leading cause of preventable death and is responsible for nearly seven 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 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.
