A Study to Assess Cardiovascular Outcomes Following Treatment With Omarigliptin (MK-3102) in Participants With Type 2 Diabetes Mellitus (MK-3102-018)
A Randomized, Double-blind, Placebo-controlled, Multicenter Study to Assess Cardiovascular Outcomes Following Treatment With MK-3102 in Subjects With Type 2 Diabetes Mellitus
The purpose of this study is to evaluate the cardiovascular (CV) safety profile of omarigliptin in participants with type 2 diabetes mellitus (T2DM). The primary hypothesis is that treatment with omarigliptin 25 mg once weekly is non-inferior to treatment with placebo and active comparators across the omarigliptin program with regard to the risk of developing a confirmed event in the primary CV composite endpoint.
The trial was amended to extend the length of the trial in order to meet FDA requirements for the post-approval assessment of cardiovascular (CV) safety. The trial now contains 2 time intervals: Period 1 and Period 2. Period 1 refers to the time interval up to this recent protocol amendment and Period 2, the time interval from this protocol amendment until the end of the study. Participants in Period 1 will be re-consented and continue into Period 2. If required, additional participants will be enrolled in Period 2. Stage 1 refers to the prefiling United States Food and Drug Administration (US FDA) requirement to rule out a 80% increased CV risk. Stage 2 refers to the US FDA post-marketing requirement to rule out a 30% increased CV risk. The Stage 1 assessment of CV risk occurred during Period 1 and was based on a meta-analysis of major adverse CV events (MACE) and unstable angina across the omarigliptin Phase 2/Phase 3 program. The Stage 2 assessment will be based on MACE in P018 alone including CV events from both Period 1 and Period 2.
