Pharmacotherapies for Alcohol and Substance Use Disorders Alliance
Summary
This study is to determine if suvorexant (SUV) will reduce insomnia in 76 men and women veteran and non-veterans between the ages 21-65 with posttraumatic stress disorder (PTSD) symptoms and alcohol use disorder (AUD). All participants will have a 7-day placebo run-in period, followed by a random assignment to receive placebo or suvorexant for an additonal 14 days. Post-randomization, participants will attempt to stop drinking for two weeks and will complete daily virtual diaries and study outcome assessments via in-person clinic visits on days 7 and 14.
Description
This is a randomized, double-masked, placebo-controlled study to evaluate preliminary efficacy and safety of suvorexant (SUV) (20mg) for sleep disturbance in alcohol use disorder (AUD) and co-occurring posttraumatic stress disorder (PTSD) symptoms in approximately 76 randomized men and women veteran and non-veterans between the ages 21-65. Participants will be recruited from the University of Texas Health Science Center at Houston (UTHealth) Trauma and Recovery Center (TRC) and the University of California - Los Angeles (UCLA) (in collaboration with West Los Angeles VA Medical Center).
