A Study of Omarigliptin (MK-3102) in Participants With Type 2 Diabetes Mellitus With Chronic Kidney Disease or Kidney Failure on Dialysis (MK-3102-019)

A Phase III, Multicenter, Randomized, Double-blind Study to Evaluate the Efficacy and Safety of MK-3102 Versus Placebo in Subjects With Type 2 Diabetes Mellitus With Moderate or Severe Chronic Kidney Disease or Kidney Failure on Dialysis Who Have Inadequate Glycemic Control.

The purpose of this study is to evaluate the efficacy and safety of omarigliptin in participants with type 2 diabetes mellitus and moderate or severe chronic renal insufficiency or end stage renal disease on dialysis with inadequate glycemic control. The primary hypothesis of the study is that omarigliptin compared to placebo produces greater reduction in glycosylated hemoglobin (A1C) after 24 weeks.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Glycosylated Hemoglobin (A1C) at Week 24	A1C is measured as a percent.

The cLDA model included terms for treatment, renal insufficiency stratum, baseline treatment with insulin stratum, time, the interaction of time by treatment, the interaction of time by renal insufficiency stratum, and the interaction of time by baseline treatment with insulin stratum.	Baseline and Week 24
Percentage of Participants Who Experienced at Least One Adverse Event (Phase A: 24-week Placebo Controlled Period)	An adverse event is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. Presented data exclude data after glycemic rescue.	Up to 28 weeks (including 28 days following the last dose of study therapy for participants who discontinued study drug)
Percentage of Participants Who Discontinued Study Drug Due to an Adverse Event (Phase A: 24-week Placebo Controlled Period)	An adverse event is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.
