A Multisite Double-Blind, Placebo-Controlled Trial of Quetiapine Fumarate XR in Very Heavy-Drinking Alcohol-Dependent Patients
This double-blind, randomized placebo-controlled trial evaluated the efficacy and safety of quetiapine, recruiting 224 alcohol-dependent patients, 20% women and 18% ethnic minorities, from 5 sites. All subjects received either quetiapine or placebo and Medical Management behavioral intervention. Patients were stratified on gender, clinical site, and reduction in drinking prior to randomization. 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. Results from a subgroup analysis suggest that patients who reduced their drinking prior to randomization had significantly better drinking outcomes during the maintenance phase. No significant interactions, however, were observed between reducer status and treatment group. Finally, 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 study sponsor was the National Institute on Alcohol Abuse and Alcoholism’s (NIAAA) Clinical Investigations Group (NCIG). The data set was prepared by NIAAA and the VA Maryland Health Care System, the trial’s Coordinating Center and was reviewed by CSR Incorporated.
