What happens next in GLP-1 — and when.

Trial results

Tirzepatide for Alcohol Use Disorder

NCT06994338 on ClinicalTrials.gov · last registry update 2025-10-14

A small phase 2 — 42 participants, against a typical 110. Its estimated completion date, 31 August 2026, has passed with no update to the record. Primary outcome, as filed: Number of heavy drinking days. A lapsed estimate is not a result and not a failure — sponsors are slow to refile — but ClinicalTrials.gov marks it nowhere on the record, so it is noted here. tirzepatide is approved in the US, but not for alcohol use disorder — a registration here is not an approval, and most drugs tested in a new condition never get one for it.
