Achieve Reports Financial Results for Fourth Quarter and Year-End 2020 and Provides Corporate Update

SEATTLE, WA and VANCOUVER, BC / ACCESSWIRE / March 11, 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, today announced fourth quarter and year-end 2020 financial results and provided an update on the cytisinicline clinical development program.

Recent Events & Highlights

• Initiated the Phase 3 ORCA-2 clinical trial evaluating the efficacy and safety of 3 mg cytisinicline dosed 3 times daily compared to placebo in 750 adult smokers at 15 clinical sites in the United States
• Presented data on smoker and e-cigarette user attitudes and perceptions on quitting at the Society for Research on Nicotine and Tobacco (SRNT) Annual Meeting on February 24, 2021
• Closed financing of $17.3 million, prior to deducting underwriting discounts and commissions and estimated offering expenses, in December 2020
• Facilitated Smoking Cessation Key Opinion Leader Virtual Roundtable in November 2020

"We concluded 2020 in the best financial position since the Company's inception and with the Phase 3 ORCA-2 trial underway at 15 well-established smoking cessation research centers in the United States. As we look to the year ahead, our focus will continue to be on execution of this pivotal trial, completion of additional NDA-enabling activities, and exploration of new opportunities for expansion into additional populations, such as vaping and e-cigarette users, who may benefit from a new cessation therapeutic option like cytisinicline," commented John Bencich, Chief Executive Officer of Achieve.

Phase 3 ORCA-2 Trial
Achieve's first Phase 3 ORCA-2 trial was initiated in October 2020 and will randomize 750 U.S. smokers to one of three study arms to determine the efficacy and safety of cytisinicline administered for either 6 or 12 weeks, compared to placebo. The primary endpoint is biochemically verified continuous abstinence during the last 4 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. The trial is expected to complete enrollment by the middle of the 2021.

Data Highlighting Smoker Dissatisfaction with Available Treatments Presented at SRNT
Achieve data presented at the SRNT Annual Meeting in February 2021 provided insights into current and former smokers' perceptions on currently available cessation treatment options. In a survey of 1,122 individuals, overall satisfaction and perceived efficacy with available therapies was low, with the best performing treatment leading to satisfaction in less than one-third of the respondents. The study found a majority of prescription cessation medication users do not complete their full 3-month course of therapy, with 53% reporting less than 1 month of use. Smokers reported side effects and lack of efficacy as the most common reason for discontinuation or lack of initiation with varenicline or bupropion.

Data Elucidating Vaping/e-Cigarette Users Behavior and Quitting Intentions Presented at SRNT
Two Achieve posters were presented at the SRNT Annual Meeting in February 2021 reporting findings from a survey of 508 users of nicotine vape products. The results showed that the primary reason to initiate e-cigarettes/vaping was to quit combustible cigarettes. While proven successful in the cohort of subjects who only utilize vape, dual users, those who vape but also continue to smoke, reported 2-times heavier nicotine use than their counterparts. Additionally, the data indicated that 73% of e-cigarette/vape users intend to quit vaping in the next 3-12 months. Of those who intend to do so in the next 3 months, more than half reported they would be "very/extremely likely to try a new prescription product" to help them quit.

Completed $17.3 Million Financing in December 2020
In December 2020, Achieve announced the closing of an underwritten public offering of 2,472,500 shares of its common stock at a public offering price of $7.00, for total gross proceeds of $17.3 million, prior to deducting underwriting discounts and commissions and estimated offering expenses. This included the full exercise of the underwriter's over-allotment option to purchase an additional 322,500 shares of common stock.

Virtual Smoking Cessation KOL Roundtable on November 17, 2020
Achieve hosted a virtual roundtable on cytisinicline and smoking cessation in November 2020. Five esteemed experts in the field of smoking cessation discussed the ongoing Phase 3 ORCA-2 trial, reviewed recent cytisinicline data, and presented evidence supporting the importance of smoking cessation in the midst of the COVID-19 pandemic.

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. Cytisinicline is an investigational product candidate being developed for treatment of nicotine addiction, and has not been approved by the FDA for any indication in the U.S.
