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 treatment period is composed of a 24-week double-blind period (Phase A) and a 28-week open-label period (Phase B). During Phase A, participants will received either omarigliptin 25 mg or a matching placebo. During Phase, B all participants will receive omarigliptin 25 mg. All participants will remain on a stable dose and administration of a single oral antihyperglycemic basal medication.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Who Discontinued From the Study Due to an Adverse Event During Phase A
Time Frame: Up to 24 weeks
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.
Up to 24 weeks
Percentage of Participants Who Experienced at Least One Adverse Event Excluding Data After Glycemic Rescue During Phase A
Time Frame: Up to 24 weeks
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. Glycemic rescue criteria were: fasting plasma glucose (FPG) of >240 mg/dL, 2 times, (Week 4 to Week 24) and after Week 24, FPG >200 mg/dL, 2 times. Glycemic rescue was achieved through up-titration of basal medication (1st rescue) and through the use of metformin or glimepiride (2nd rescue).
Up to 24 weeks
Percentage of Participants Who Experienced at Least One Adverse Event Excluding Data After Glycemic Rescue During the Overall Study
Time Frame: Up to 52 weeks
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. Glycemic rescue criteria were: fasting plasma glucose (FPG) of >240 mg/dL, 2 times, (Week 4 to Week 24) and after Week 24, FPG >200 mg/dL, 2 times. Glycemic rescue was achieved through up-titration of basal medication (1st rescue) and through the use of metformin or glimepiride (2nd rescue). These results represent the accrual of events over different treatment intervals: 52 weeks, Omarigliptin (Phase A+B) group, defined as the double-blind period and open-label extension period versus 28 weeks for the placebo switching to Omarigliptin group defined as the open-label extension period only.
Up to 52 weeks
Percentage of Participants Who Discontinued From the Study Due to an Adverse Event During the Overall Study
Time Frame: Up to 52 weeks
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.

Up to 52 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Hemoglobin A1c (HbA1c) at Week 24
Time Frame: Baseline and Week 24
HbA1C is blood marker used to report average blood glucose levels over a prolonged periods of time and is reported as a percentage (%). Thus, this change from baseline reflects the Week 24 HbA1c minus the Week 0 HbA1c.

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
