NCT07588438 on ClinicalTrials.gov · last registry update 2026-05-19

An unusually large phase 4: 160 participants, more than double the 72 typical for the stage. Due to report 10 August 2027, alongside 39 other tracked readouts that quarter. Primary outcome, as filed: Mean Percent Change From Baseline in Body Weight at 52 Weeks. Sponsors move these dates routinely; any movement since this site started watching is listed below. tirzepatide is already approved in the US for obesity and type 2 diabetes, so this is asking a further question rather than establishing the drug works at all.
