Primary Outcome Measures:
  • Percentage of Participants Who Experienced at Least One Adverse Event Excluding Data After Glycemic Rescue During Phase A [ Time Frame: Up to 24 weeks ] [ Designated as safety issue: Yes ]
    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).

  • 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 ] [ Designated as safety issue: Yes ]
    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→Omarigliptin group defined as the open-label extension period only.

  • Percentage of Participants Who Discontinued From the Study Due to an Adverse Event During Phase A [ Time Frame: Up to 24 weeks ] [ Designated as safety issue: Yes ]
    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.

  • Percentage of Participants Who Discontinued From the Study Due to an Adverse Event During the Overall Study [ Time Frame: Up to 52 weeks ] [ Designated as safety issue: Yes ]
    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→Omarigliptin group defined as the open-label extension period only.


Secondary Outcome Measures:
  • Change From Baseline in Hemoglobin A1c (HbA1c) at Week 24 [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
    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.
