NCT ID: NCT06727331

Last Updated: 2025-12-15

Basic Information

• Recruitment Status: RECRUITING
• Clinical Phase: PHASE2
• Total Enrollment: 20 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2025-09-15
• Study Completion Date: 2026-07-31

Brief Summary

This is a pilot, 4-week, double-blind, placebo-controlled, randomized trial of individuals with alcohol use disorder (AUD) to receive weekly injections of either tirzepatide (n=10) or matching placebo (n=10). The primary aim is to determine the effects of tirzepatide on cue-reactivity among individuals with AUD. The secondary aim is to assess the safety and preliminary efficacy of tirzepatide for AUD.

Detailed Description

Participants include N=20 men and women with DSM5 diagnosis of AUD. Potential participants will be screened and enrolled only if they meet full inclusion criteria. After screening and baseline procedures (Visit 1) are complete, participants will be randomized to receive either tirzepatide or placebo. Following randomization, participants will be scheduled for five study visits (Visits 2-6). Each visit will last approximately 1 hour, except for study visits 1 and 6 which will take no more than 3 hours in order to conduct additional neurocognitive testing, including cue-induced cravings and decision-making tests. At all study visits, participants will complete vital signs, weight, urine toxicology testing, a blood draw for glucose, and questionnaires probing secondary outcomes (i.e. anxiety and depression, suicidality, substance use, opioid withdrawal symptoms, cravings, etc). At study visits 2-5, the weekly dose of tirzepatide or placebo will be administered, and assessment of adverse events will also be completed. Both participants and study staff (including raters) will be blinded to active drug vs. placebo. At visit 1, subjects' expectations about their potential treatment will be queried. The final visit, visit 6, also called the follow-up visit, will also assess subjects' guess as to which treatment they received. The medication will be purchased from the manufacturer and stored by IDS. The IDS will extract the tirzepatide and draw the dose into syringes, which will match visually with the placebo doses.
