Thursday, November 7, 2024

SEATTLE, Wash and VANCOUVER, British Columbia, November 7, 2024 (GLOBE NEWSWIRE) -- Achieve Life Sciences, Inc. (Nasdaq: ACHV), a late-stage pharmaceutical company dedicated to the global development and commercialization of cytisinicline for the treatment of nicotine dependence, today announced its financial results for the third quarter of 2024 and provided an update on its cytisinicline development program.

Recent Highlights

“This is an incredibly exciting time at Achieve, as we remain steadfastly focused on advancing cytisinicline to address the urgent need for effective smoking and vaping cessation solutions,” stated Rick Stewart, Chief Executive Officer of Achieve. "With increased attention at the regulatory level and in the media on nicotine dependence, coupled with the lack of innovation in this field for over 20 years, we are committed to bringing the first new prescription therapy to market. We remain on track for our planned NDA submission in the second quarter of 2025 and are driven by the potential to make a meaningful difference in public health.”

Completed Enrollment for ORCA-OL Trial

Achieve has successfully completed enrollment in the ORCA-OL clinical trial, which includes 479 participants across 29 U.S. sites. This study is evaluating the long-term safety of a 3 mg cytisinicline regimen for smoking and vaping cessation, a key requirement for Achieve’s NDA submission planned for the second quarter of 2025. The trial rapidly enrolled in just over four months and Achieve believes the number of participants will be sufficient to meet the long-term safety requirements for submission.

Additionally, the trial’s Data Safety Monitoring Committee completed its initial review and concluded that there are no safety concerns, the overall safety profile appears to be excellent, and the study may proceed as planned with no modifications.

Presented at the FDA and NIH Joint Public Meeting

Dr. Cindy Jacobs, President and Chief Medical Officer, represented Achieve at the FDA and NIH Joint Meeting, where she emphasized the urgent need for increased industry and agency collaboration to advance treatment options for smoking cessation and nicotine dependence. Dr. Jacobs highlighted that cytisinicline is currently the only late-stage treatment in clinical development that has successfully demonstrated cessation efficacy and excellent tolerability in two randomized Phase 3 trials conducted in over 1,600 participants. Full comments from the public meeting have been submitted to the public docket and are available on the FDA website.

Granted Breakthrough Therapy Designation for Cytisinicline Vaping Cessation Indication

In July, the FDA granted Breakthrough Therapy designation for cytisinicline for nicotine e-

cigarette, or vaping, cessation, which is intended to expedite the development and review of treatments for serious conditions that show promising clinical evidence of significant improvement over current therapies.

Enhanced Leadership Team Expertise

Achieve’s recent leadership appointments underscore a commitment to strategic growth and maximizing shareholder value. With Richard Stewart returning as CEO and Thomas King serving as Executive Chairman, Achieve is well-positioned to drive its focused growth strategy forward. The commercial launch readiness team will be led by Chief Commercial Officer, Jaime Xinos, who will focus efforts on execution of activities in preparation for cytisinicline entry to the U.S. market. Additionally, Dr. Mark Rubinstein’s expertise in nicotine dependence, now as Head of Medical Affairs, will help to expand stakeholder awareness of Achieve and the potential public health impact of cytisinicline.

As of September 30, 2024, the company’s cash, cash equivalents, restricted cash, and short-term investments totaled $42.9 million. Total operating expenses for the three and nine months ended September 30, 2024 were $12.5 million and $26.9 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. There are approximately 29 million adults who smoke combustible cigarettes.1 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.2,3 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.3

In addition, there are over 11 million adults in the United States who use e-cigarettes, also known as vaping.4 In 2024, approximately 1.6 million middle and high school students in the United States reported using e-cigarettes.5 There are no FDA-approved treatments indicated specifically as an aid to nicotine e-cigarette cessation. Cytisinicline has been granted Breakthrough Therapy designation to address this critical need.

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 nicotine craving symptoms, and reducing the reward and satisfaction associated with nicotine products. Cytisinicline is an investigational product candidate being developed for the treatment of nicotine addiction and has not been approved by the Food and Drug Administration for any indication in the United States.
