A Study of Tirzepatide (LY3298176) in Participants With Type 2 Diabetes Mellitus

NCT03131687 on ClinicalTrials.gov · last registry update 2019-08-20

An unusually large phase 2: 318 participants, more than double the 110 typical for the stage. The sponsor logged completion for 1 August 2018. Primary outcome, as filed: Change From Baseline to Week 26 in Hemoglobin A1c (HbA1c) Bayesian Dose Response. tirzepatide is already approved in the US for type 2 diabetes, so this is asking a further question rather than establishing the drug works at all.
