What this trial studies

This Phase 2 randomized controlled trial will evaluate the safety and efficacy of pregnenolone, administered at a dose of 300 mg twice daily, compared to a placebo over a 12-week period in individuals diagnosed with Alcohol Use Disorder (AUD). Participants will receive behavioral counseling and will be assessed twice weekly for alcohol use outcomes, cravings, anxiety, depression, and overall physical well-being. The study aims to determine the tolerability of pregnenolone and its potential benefits in reducing alcohol consumption and improving mental health symptoms associated with AUD.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for individuals struggling with Alcohol Use Disorder.

How similar studies have gone: While the use of pregnenolone for AUD is a novel approach, previous studies on similar interventions have shown varying degrees of success.
