Provides Corporate Update

Company to host conference call at 4:30 PM EST today, November 14, 2022

SEATTLE, WA and VANCOUVER, British Columbia, November 14, 2022 (GLOBE NEWSWIRE) — Achieve Life Sciences, Inc. (NASDAQ: ACHV), a late-stage clinical pharmaceutical company committed to the global development and commercialization of cytisinicline for smoking cessation and nicotine dependence, today announced third quarter 2022 financial results and provided an update on the cytisinicline development program.

Highlights

“Completing enrollment in the ORCA-3 trial this quarter and more recently, the ORCA-V1 trial, has moved us closer to potentially bringing a critical treatment option to people who wish to end their nicotine dependence,” stated John Bencich, CEO of Achieve Life Sciences. “We are excited to build upon the previously reported cessation benefit, safety, and tolerability of cytisinicline and look forward to releasing top-line data for both trials in the second quarter of next year.”

Completed Enrollment in Confirmatory Phase 3 ORCA-3 Trial

In September, Achieve announced the completion of targeted enrollment of 750 adult smokers in its confirmatory Phase 3 ORCA-3 clinical trial of cytisinicline being conducted across 20 clinical trial locations in the United States. The participants in ORCA-3 were randomized to one-of-three study arms to determine the efficacy and safety of cytisinicline administered for either 6 or 12 weeks, compared to placebo. Similar to the previously reported ORCA-2 trial, the primary endpoint is biochemically verified continuous abstinence during the last four weeks of treatment in the 6 and 12-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. Topline ORCA-3 data are currently expected to be reported in Q2 of 2023.

Early Completion of Enrollment in Phase 2 ORCA-V1 Trial

In November, Achieve announced the early completion of targeted enrollment of 150 adult users of nicotine e-cigarettes in the Phase 2 ORCA-V1 clinical trial of cytisinicline being conducted across 5 clinical trial locations in the United States. Participants were randomized in this two-arm trial to receive either cytisinicline, dosed at 3 mg three times daily, or placebo, for a period of 12 weeks. All subjects are also receiving standardized behavioral support throughout the trial. The primary outcome assessment of ORCA-V1 will be continuous vaping abstinence during the final 4 weeks of treatment. ORCA-V1 is supported through grant funding from the National Institute on Drug Abuse (NIDA) of the National Institutes of Health (NIH). Topline results are expected to be reported in Q2 of 2023.

Sopharma Expansion of Manufacturing Facility

Achieve’s commercial manufacturing partner, Sopharma, financed and completed the build out of a new dedicated cytisinicline API purification suite at its primary manufacturing plant. At an estimated build out cost of more than €3 million, the newly completed API suite significantly expands the capacity to produce quantities of cytisinicline at a global scale. The new API suite complements Sopharma’s capacity to produce nearly 3 billion tablets annually.

As of September 30, 2022, the company’s cash, cash equivalents, and restricted cash were $18.2 million. Total operating expenses for the three and nine months ended September 30, 2022 were $12.6 million and $29.9 million, respectively.

About Achieve and Cytisinicline 

Achieve’s focus is to address the global smoking health and nicotine addiction epidemic through the development and commercialization of 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

In addition, there are nearly 11 million adults in the United States who use e-cigarettes, also known as vaping.³ While nicotine e-cigarettes are thought to be less harmful than combustible cigarettes, they remain addictive and can deliver harmful chemicals which can cause lung injury or cardiovascular disease.⁴ In 2021, e-cigarettes were the most commonly used tobacco product reported by 1.72 million high school students.⁵ Research shows adolescents who have used e-cigarettes are seven times more likely to become smokers one year later compared to those who have never vaped.⁶ Currently, there are no FDA-approved treatments indicated specifically as an aid to nicotine e-cigarette cessation.

Cytisinicline is a plant-based alkaloid with a high binding affinity to the nicotinic acetylcholine receptor. It is believed to aid in treating nicotine addiction for smoking and e-cigarette cessation by interacting with nicotine receptors in the brain, reducing the severity of withdrawal symptoms, and reducing the reward and satisfaction associated with nicotine products. 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.
