SEATTLE, WA & VANCOUVER, BC / ACCESSWIRE / September 14, 2021 / Achieve Life Sciences, Inc. (NASDAQ:ACHV), a clinical-stage pharmaceutical company committed to the global development and commercialization of cytisinicline for smoking cessation and nicotine addiction, announced that cytisinicline data will be presented at two sessions during the upcoming Society for Research on Nicotine & Tobacco (SRNT-E) Conference to be held virtually September 15-17, 2021.

Presentation Details

• 'Cytisinicline may benefit smokers who previously failed to quit smoking with varenicline: A subgroup analysis of the ORCA-1 trial'
  • A subgroup analysis from the ORCA-1 Phase 2 study of smokers who had previously failed Chantix® (varenicline) demonstrated a Week 4 abstinence rate of 51.3% upon treatment with cytisinicline using the three times daily (TID) regimen, compared with 15.8% with placebo (p= 0.009). The estimated Odds Ratios for smoking cessation through Weeks 5-8 were 1.8 for the titration and 4.3 for the TID regimen. The cytisinicline TID regimen appeared to be more effective for smokers who had previously failed to quit on varenicline than the titration regimen.
  • The data will be presented on Thursday, September 16^th, Oral Session 5:'Smoking cessation interventions in special populations'.
• 'Time to Sustained Abstinence with Cytisinicline in the ORCA-1 trial'
  • A new analysis of the ORCA-1 Phase 2 study determined that smokers treated in the study with cytisinicline showed an earlier onset of sustained abstinence compared with placebo. Smokers who received the cytisinicline 3 mg TID had the shortest time to sustained smoking abstinence with a median of only 7 days of treatment compared to 18 days for placebo.
  • The data will be presented on Friday, September 17^th, Poster Session 5:'Clinical'.

'This additional analysis continues to reinforce our belief that the 3 mg dose of cytisinicline taken three times daily provides the greatest potential for smokers, regardless of prior treatments, to successfully quit,' commented John Bencich, CEO of Achieve. 'We are also pleased to have new insights on the short time to response seen with cytisinicline. We believe this early abstinence could inspire smokers to continue their treatment and stay quit.'

Achieve recently announced completion of enrollment in the Phase 3 ORCA-2 clinical trial, evaluating cytisinicline as a treatment for combustible cigarette cessation. Topline results from the ORCA-2 trial are expected in the first half of 2022. For more information on Achieve Life Sciences and cytisinicline please visit www.achievelifesciences.com.

About Achieve and 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 U.S. 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 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.
