SEATTLE, Wash and VANCOUVER, British Columbia, August 13, 2024 (GLOBE NEWSWIRE) -- Achieve Life Sciences, Inc. (NASDAQ: ACHV), a late-stage pharmaceutical company dedicated to the global development and commercialization of cytisinicline for smoking cessation and nicotine dependence, today announced its financial results for the second quarter of 2024 and provided an update on its cytisinicline development program.

Recent Highlights

"We are extremely proud of the significant milestones we have accomplished over the last few months, including the granting of Breakthrough Therapy designation for cytisinicline for vaping cessation, which highlights the urgent need for an effective treatment to help the millions of people who are battling nicotine vape addiction,” stated John Bencich, Chief Executive Officer of Achieve. “Additionally, we initiated and are making great progress in the ORCA-OL trial evaluating long-term cytisinicline exposure moving us closer to our expected NDA filing in the first half of 2025.”

Cytisinicline for Vaping Cessation Granted FDA Breakthrough Therapy Designation

The U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy designation for cytisinicline for nicotine e-cigarette, or vaping, cessation. The designation aims to accelerate the development and review process for promising drugs that are intended to treat serious conditions and when preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapies. There are currently no FDA-approved treatments specifically indicated for vaping cessation. Achieve plans to hold an End-of-Phase 2 meeting with the FDA’s multidisciplinary team under this Breakthrough Therapy designation before the end of the year.

Refinanced Outstanding Loan with Silicon Valley Bank

Achieve announced that it has entered into a debt refinancing agreement of up to $20 million with SVB, a division of First-Citizens Bank & Trust Company (FCB). The new loan agreement refinances the existing debt facility with SVB and extends the maturity date from August 1, 2024 to December 1, 2027. Achieve’s obligations under the prior agreement were satisfied in full, and the previous agreement was terminated in connection with the new contingent convertible debt agreement.

Joined Russell 3000® and Russell Microcap® Indexes
Achieve received its inclusion in the U.S. Russell 3000® and Russell Microcap® Indexes, which became effective July 1, 2024. This inclusion enhances the company's visibility among investors, reflecting Achieve’s strong business fundamentals and market potential for cytisinicline as a treatment for nicotine dependence.

Initiated ORCA-OL Trial

The open-label, ORCA-OL trial, was initiated in May 2024 and will incorporate participants from earlier cytisinicline clinical trials to efficiently compile safety data over extended periods, specifically focused on subjects treated with cytisinicline for up to one year. Enrollment is ongoing at 29 clinical trial sites in the U.S. with more than half of the proposed 650 participants already enrolled on the study. The necessary clinical data from ORCA-OL is anticipated to be available to support an NDA submission in the first half of 2025.

ORCA-V1 Data Presented at the SGIM Annual Meeting

Data from the Phase 2 ORCA-V1 vaping cessation trial were presented at the SGIM Annual Meeting. The findings showed that cytisinicline more than doubled the likelihood of quitting nicotine e-cigarettes compared to placebo. Cytisinicline has shown promise in aiding smoking cessation and may also help individuals quit vaping.

Financial Results

As of June 30, 2024, the company’s cash, cash equivalents, restricted cash and short-term investments total $61.3 million. Total operating expenses for the three and six months ended June 30, 2024 were $8.4 million and $14.4 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 in the United States alone who smoke combustible cigarettes.1Tobacco 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.4In 2023, approximately 2.1 million middle and high school students in the United States reported using e-cigarettes.5 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 the treatment of nicotine addiction and has not been approved by the Food and Drug Administration for any indication in the United States.
