Study Endpoints

Primary Endpoints

Change From Baseline in A1C at Week 24
Baseline and Week 24

A1C is a measure of the percentage of glycated hemoglobin in the blood. Participant whole blood samples were collected at baseline and Week 24 to determine the least squares mean A1C change from baseline.

Percentage of Participants Who Experienced at Least One Adverse Event
Up to 27 weeks (including 3-week follow-up)

An adverse event is defined as any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an adverse event. Data presented below excludes data after initiation of glycemic rescue therapy.

Percentage of Participants Who Discontinued Study Drug Due to an Adverse Event
Up to 24 weeks

An adverse event is defined as any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an adverse event. Data presented below excludes data after initiation of glycemic rescue therapy.

Percentage of Participants Who Experienced at Least One Adverse Event (AE)
Up to Week 27

An AE is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study. Data presented exclude data following the initiation of glycemic rescue. The safety database was analyzed in a standard fashion in the all participants as treated (APaT) population for all participants who took at least one dose of study medication. This analysis may have been confounded by the use of metformin prohibited by the protocol (see efficacy results description above).

Percentage of Participants Who Discontinued Study Drug Due to an AE
Up to Week 24

An AE is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study. Data presented exclude data following the initiation of glycemic rescue. The safety database was analyzed in a standard fashion in the APaT population for all participants who took at least one dose of study medication. This analysis may have been confounded by the use of metformin prohibited by the protocol (see efficacy results description above).

Change From Baseline in Glycosylated Hemoglobin (A1C) at Week 24 (Phase A)
Baseline and Week 24

A1C is measured as a percent. Change from baseline in A1C at Week 24 was analyzed using a constrained longitudinal data analysis (cLDA) method with a restriction of the same baseline mean across treatment groups. The cLDA model included terms for treatment, time, and the interaction of time by treatment.

Percentage of Participants Who Experienced at Least One Adverse Event (Phase A+B)
Up to 107 weeks

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.

Percentage of Participants Who Discontinued Study Drug Due to an Adverse Event (Phase A+B)
Up to 104 weeks

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.

Percentage of Participants Who Experienced an Adverse Event Which Were Included Under the System Order Class of Investigations (Phase A+B)
Up to 104 weeks

Change From Baseline in Hemoglobin A1c (A1C) at Week 24 (Phase A, FAS Population)
Baseline and Week 24

A1C (%) is used to report average blood glucose levels over prolonged periods of time. Because it was discovered that in another omarigliptin study (MK-3102-028, NCT01814748) subjects had taken metformin (prohibited per protocol, and taken without investigator knowledge), after unblinding of Phase A of this study, an analysis of metformin levels was performed on stored Week 18 blood samples. Of the subjects not rescued with metformin prior to Week 18, 10% in the omarigliptin group and 20% in the placebo group had levels showing that they were taking metformin (prohibited per protocol). The use of prohibited metformin disproportionately by the placebo group may have resulted in a smaller than expected treatment effect for efficacy outcome measures (see post-hoc analysis).

Frequently asked questions about Omarigliptin

What is Omarigliptin used for?

Omarigliptin is an investigational small molecule being developed for the treatment of Type 2 Diabetes Mellitus. It has been studied in patients with inadequate glycemic control, including those with chronic renal insufficiency. The drug is in clinical development but is not approved.

Who makes Omarigliptin?

Omarigliptin is being developed by Merck & Company, Inc., which trades under the ticker symbol MRK. The company has sponsored multiple clinical trials of the drug across various phases.

What phase is Omarigliptin in?

Omarigliptin is currently in Phase 1 clinical development. While it has completed Phase 2 and Phase 3 trials, the most advanced ongoing development stage is Phase 1, and the drug remains investigational and not approved.

What clinical trials is Omarigliptin in?

Omarigliptin has been studied in several completed trials, including NCT01217073 (Phase 2 dose-range finding), NCT01407276 (Phase 1 in renal impairment), NCT01814748 (Phase 3 in younger adults), and NCT01841697 (Phase 3 comparing to sitagliptin). All trials are completed.

Is Omarigliptin the same as MK-3102?

Yes, Omarigliptin is also known as MK-3102. Clinical trial titles and records refer to the drug by both names, such as in NCT01407276, which is titled 'A Study of Omarigliptin (MK-3102) in Participants With Impaired Renal Function.'

How does Omarigliptin work?

Omarigliptin is a small molecule that targets dipeptidyl peptidase-4 (DPP-4), an enzyme involved in glucose metabolism. By inhibiting DPP-4, it helps regulate blood sugar levels in patients with Type 2 Diabetes Mellitus.
