SAN FRANCISCO, Oct. 17, 2019 /PRNewswire/ -- Amygdala Neurosciences (a private company) announced today the start of dosing in the National Institute on Alcohol Abuse and Alcoholism (NIAAA, an Institute of the National Institutes of Health (NIH)) sponsored Phase 2 proof-of-concept study of ANS-6637 in patients with alcohol use disorder. In the United States, every year 88,000 people die from alcohol-related causes, there are 17 million people with alcohol use disorder, and annual costs associated with alcohol use disorder exceed $250 billion.
ANS-6637 has an anti-craving mechanism of action working in the brain's nucleus accumbens to reduce the dopamine surge responsible for craving. ANS-6637 has been shown to reduce craving and drug seeking behavior in preclinical studies against multiple addictive agonists and has the potential for use as pharmacotherapy for substance and behavior-based addictions.
"Today we achieved the important milestone, enrolling a patient into our first Phase 2 clinical trial," said Peter Strumph, Amygdala co-founder and CEO. "In addition, we plan to initiate several other Phase 2 proof-of-concept studies early next year including an NIH HEAL Initiative funded Phase 2 study of ANS-6637 in patients with opioid use disorder and a Phase 2 study of ANS-6637 as an aide to smoking cessation."
ANS-6637 is a selective and reversible ALDH2 inhibitor, a new chemical entity with a novel mechanism of action for treating substance use disorder. Based on its mechanism of action in the brain to prevent pathophysiologic dopamine surge without changes to basal dopamine (Nature Medicine 16:1024, 2010), ANS-6637 has the potential to prevent drug seeking behavior, craving and relapse. In preclinical studies, ALDH2 inhibition reduced self-administration, cue- and drug-primed relapse in nicotine, alcohol, cocaine, heroin, methamphetamine and binge eating models and also demonstrated anti-anxiety properties in models of stress. Amygdala acquired the asset ANS-6637 as a spin-out from Gilead Sciences. ANS-6637 has completed extensive Phase 1 studies in 150 human subjects and is currently in Phase 2 clinical development.
About the Clinical Study
This study is a 3-arm, double-blind, randomized, placebo-controlled, parallel group, 3-site study designed to assess the effects of ANS-6637 as compared with placebo on responses to in vivo alcohol cue exposure in the human laboratory setting. The study will enroll 81 treatment seeking patients who meet DSM-5 criteria for at least moderate alcohol use disorder. Endpoints include laboratory paradigm alcohol cue-elicited alcohol craving, percentage of subjects with no heavy drinking days, percentage of subjects abstinent from alcohol, and safety. Additional details about the study, "Human Laboratory Study of ANS-6637 for Alcohol Use Disorder," are available on clinicaltrials.gov using the identifier NCT03970109.
