Orexin Receptor Antagonism for the Treatment of Alcohol Use Disorder and Stress-Related Drinking

Orexin Receptor Antagonism for the Treatment of Alcohol Use Disorder and Stress-Related Drinking (NCT07214207) is a Phase 2 interventional studying Alcohol Use Disorder, sponsored by Ohio State University. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

The goal of this clinical trial is to learn if, how, and for whom suvorexant (SUV) works to treat alcohol use disorder (AUD). The main questions it aims to answer are: * Is SUV effective for AUD? * Does SUV dampen stress reactivity? * Can the researchers develop a biomarker for SUV treatment response? Researchers will compare SUV to a placebo (a look-alike substance that contains no drug) to see if drug SUV works to treat AUD. Participants will: * Take 10mg capsules of SUV or a placebo orally each night before bedtime for 8-weeks. * Visit the laboratory before (baseline), 4-weeks (mid-point), and 8-weeks (end-point) after taking SUV or placebo that include the psychophysiological stress paradigm (electromyography; EMG). * Complete daily reports of medication adherence, side-effects, sleep, alcohol use, and mood will be collected via smartphones during the 8-week medication trial.

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Alcohol Use Disorder and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 250 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Alcohol Use Disorder subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Treatments Being Tested

DRUG

Suvorexant 10 mg

This study is a double-blind study. Participants will complete an initial screening visit and pre-treatment, mid-treatment, and post-treatment lab visits. Suvorexant (SUV) will be placed in opaque capsules with dextrose filler. Following the pre-treatment visit, participants will receive a labeled blister pack with 28 pills and be instructed to take one pill orally about 30 minutes prior to sleep time each night for 4 weeks. Participants will be provided education about common side effects. At the end of the 4-weeks, participants will return to the lab to complete a mid-treatment lab visit, receive a second labeled blister pack, and will be instructed to continue taking one pill orally about 30 minutes prior to sleep time each night for 4-weeks. Participants will return to complete a post-treatment lab visit. Participants will complete daily surveys to monitor side effects throughout the 8-week medication trial.

OTHER

Placebo

This study is a double-blind study. Participants will complete an initial screening visit and pre-treatment, mid-treatment, and post-treatment lab visits. The placebo pill will be identical in appearance to suvorexant but will contain only dextrose. Following the pre-treatment visit, participants will receive a labeled blister pack with 28 pills and be instructed to take one pill orally about 30 minutes prior to sleep time each night for 4-weeks. Participants will be provided education about common side effects. At the end of the 4-weeks, participants will return to the lab to complete a mid-treatment lab visit, receive a second labeled blister pack, and will be instructed to continue taking one pill orally about 30 minutes prior to sleep time each night for 4-weeks. Participants will return to complete a post-treatment lab visit. Participants will complete daily surveys to monitor side effects throughout the 8-week medication trial.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
