Limitations and caveats
Care must be taken in the interpretation of the results in this study as the non-protocol-specified prohibited use of metformin among a number of participants may have impacted the safety and efficacy results disproportionally among study arms.

ListOutcomeTime frameDescription
PrimaryChange 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).
PrimaryPercentage of Participants Who Experienced at Least One Adverse Event in Phase A (Excluding Data After Glycemic Rescue, Safety Population)Up to 27 weeks
An adverse event is any untoward medical occurrence in a participant administered study drug which does not necessarily have a causal relationship with the treatment. Adverse events may include the onset of new illness and the exacerbation of preexisting conditions. This analysis may have been confounded by use of prohibited metformin (see results above for description of the use of prohibited metformin).
PrimaryPercentage of Participants Who Discontinued From the Study Drug Due to an Adverse Event in Phase A (Excluding Data After Glycemic Rescue, Safety Population)Up to 24 weeks
An adverse event is any untoward medical occurrence in a participant administered study drug which does not necessarily have a causal relationship with the treatment. Adverse events may include the onset of new illness and the exacerbation of preexisting conditions. This analysis may have been confounded by use of prohibited metformin (see results above for description of the use of prohibited metformin).
PrimaryPercentage of Participants Who Experienced at Least One Adverse Event (Phase A + Phase B, Excluding Data After Glycemic Rescue, Safety Population)Up to 57 weeks
An adverse event is any untoward medical occurrence in a participant administered study drug which does not necessarily have a causal relationship with the treatment. Adverse events may include the onset of new illness and the exacerbation of preexisting conditions. This analysis may have been confounded by use of prohibited metformin (see results above for description of the use of prohibited metformin).
PrimaryPercentage of Participants Who Discontinued From the Study Drug Due to an Adverse Event (Phase A + Phase B, Excluding Data After Glycemic Rescue, Safety Population)Up to 57 weeks
An adverse event is any untoward medical occurrence in a participant administered study drug which does not necessarily have a causal relationship with the treatment. Adverse events may include the onset of new illness and the exacerbation of preexisting conditions. This analysis may have been confounded by use of prohibited metformin (see results above for description of the use of prohibited metformin).
SecondaryPercentage of Participants Who Achieve an A1C Goal of <7% (53 mmol/Mol) at Week 24 (Phase A, FAS Population)Week 24
A1C is a blood marker used to report average blood glucose levels over prolonged periods of time and is reported as a percentage (%). The percentage of participants who achieved A1C values \<7.0% (53 mmol/mol) in the FAS population at Week 24. 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).
SecondaryPercentage of Participants Who Achieve an A1C Goal of <6.5% (48 mmol/Mol) at Week 24 (Phase A, FAS Population)Week 24
A1C is a blood marker used to report average blood glucose levels over prolonged periods of time and is reported as a percentage (%). The percentage of participants who achieved A1C values \<6.5% (48 mmol/mol) in the FAS population at Week 24. 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).
SecondaryChange From Baseline in Fasting Plasma Glucose (FPG) at Week 24 (Phase A, FAS Population)Baseline and Week 24
Blood glucose was measured on a fasting basis (collected after an 10-hour fast). FPG is expressed as mg/dL. This change from baseline reflects the FPG level at Week 24 minus the FPG level at Week 0. 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).
SecondaryChange From Baseline in 2-hour Post Meal Glucose (PMG) at Week 24 (Phase A, FAS Population)Baseline and Week 24
Blood glucose was measured 2 hours after a meal (2-hour PMG). 2-hour PMG is expressed as mg/dL. This change from baseline in 2-hour PMG reflects the Week 24 2-hour PMG minus the Week 0 2-hour PMG. 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).
SecondaryChange From Baseline in A1C at Week 54 (Phase A + Phase B, FAS Population)Baseline and Week 54
A1C is a blood marker used to report average blood glucose levels over prolonged periods of time and is reported as a percentage (%). Thus, this change from baseline reflects the Week 54 A1C minus the Week 0 A1C. The results of the study at Week 54 may have been confounded by use of prohibited metformin (see results above for description of the use of prohibited metformin).
