ASP-8062

ASP-8062, or ASP8062, is a GABAB receptor positive allosteric modulator which is under development for the treatment of alcoholism. It was also under development for the treatment of fibromyalgia and opioid-related disorders, but development for these indications was discontinued. The drug is taken orally.

ASP-8062, or ASP8062, is a GABAB receptor positive allosteric modulator which is under development for the treatment of alcoholism.134 It was also under development for the treatment of fibromyalgia and opioid-related disorders, but development for these indications was discontinued.1 The drug is taken orally.12

Pharmacology

It shows analgesic and antiaddictive effects in animals.4567 In a polysomnography study, ASP-8062 dose-dependently enhanced slow wave sleep (SWS; deep sleep) without affecting REM sleep in humans.8 It also dose-dependently increased growth hormone (GH) release.8 The time to peak levels of ASP-8062 in humans is 1 to 4 hours and its elimination half-life is approximately 40 to 50 hours.2

Development

ASP-8062 is under development by Astellas Pharma in collaboration with the National Institute on Alcohol Abuse and Alcoholism (NIAAA).1 As of June 2023, it is in phase 2 clinical trials for alcoholism.149 The drug is the most advanced GABAB receptor positive allosteric modulator in clinical trials as of 2024.496
