A Study to Assess Cardiovascular Outcomes Following Treatment With Omarigliptin (MK-3102) in Participants With Type 2 Diabetes Mellitus (MK-3102-018)

October 10, 2018 updated by: Merck Sharp & Dohme LLC

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.
