This double-blind, randomized placebo-controlled trial evaluated the efficacy and safety of quetiapine, for the treatment of alcohol use disorder (AUD).  

  • Sponsor: The National Institute on Alcohol Abuse and Alcoholism’s Clinical Investigations Group (NCIG) 
  • NCT #: 00498628 
  • Phase:  Phase 2 
  • Treatment Arms: Quetiapine 400mg daily and matching placebo 
  • Number of clinical sites: 5  
  • Number of Participants: 224 
  • Duration: 3 months; efficacy weeks 3-11 
  • Population: Adults with Alcohol Use Disorder; 20% women; 18% ethnic minorities 
  • Other Study Details: Double-blind

Top-line Results

No differences between the quetiapine and placebo groups were detected in the primary outcome, percentage heavy-drinking days, or other drinking outcomes. Quetiapine significantly reduced depressive symptoms and improved sleep but had no effect on other nondrinking outcomes.  Quetiapine was generally well tolerated. Statistically significant adverse events that were more common with quetiapine versus placebo include dizziness, dry mouth, dyspepsia, increased appetite, sedation, and somnolence. 

The data set was prepared by NIAAA and the VA Maryland Health Care System (the Coordinating Center) and was reviewed by CSR Incorporated.
