Brief Summary:
This study will evaluate the efficacy and safety of the addition of ertugliflozin (MK-8835/PF-04971729) compared with the addition of glimepiride in participants with T2DM who have inadequate glycemic control on metformin. The primary hypothesis of this study is that after 52 weeks, the change from baseline in hemoglobin A1c (A1C) in participants treated with the addition of ertugliflozin 15 mg once daily is non-inferior compared with that in participants treated with the addition of glimepiride.

Condition or disease Intervention/treatment Phase
Type 2 Diabetes Mellitus Drug: Ertugliflozin 5 mg Drug: Ertugliflozin 10 mg Drug: Glimerpiride Drug: Placebo to Ertugliflozin Drug: Placebo to Glimepiride Drug: Metformin Drug: Sitagliptin Phase 3

Detailed Description:
The duration of the trial will be up to approximately 122 weeks. This will include a 1-week screening period, an up to 13-week wash-off/titration/dose stabilization period, a 2-week placebo run-in period, a 104-week double-blind, active comparator-controlled treatment period, and a post-treatment telephone contact 14 days after the last dose of study drug.

Primary Outcome Measures :
  1. Change From Baseline in Hemoglobin A1C (A1C) at Week 52: Excluding Rescue Approach [ Time Frame: Baseline and Week 52 ]
    A1C is blood marker used to report average blood glucose levels over prolonged periods of time and is reported as a percentage (%). A1C represents the percentage of glycated hemoglobin. This change from baseline reflects the Week 52 A1C minus the Week 0 A1C. A negative number indicates a reduction in A1C level. Participants who met glycemic rescue criteria received open-label sitagliptin glycemic rescue medication. The primary study objective was the MK-8835 15 mg vs. glimepiride comparison; the MK-8835 5mg vs glimerpiride comparison was a secondary study objective.

  2. Percentage of Participants Experiencing An Adverse Event (AE) Up to Week 106 [ Time Frame: Up to Week 106 ]
    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.

  3. Percentage of Participants Discontinuing Study Treatment Due to an AE Up to Week 104 [ Time Frame: Up to Week 104 ]
    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.


Secondary Outcome Measures :
  1. Percentage of Participants With an Adverse Event of Symptomatic Hypoglycemia Up to Week 52: Excluding Rescue Approach [ Time Frame: Up to Week 52 ]
    Symptomatic hypoglycemia was an event with clinical symptoms reported by the investigator as hypoglycemia (biochemical documentation not required). Participants who met glycemic rescue criteria received open-label sitagliptin glycemic rescue medication.

  2. Change From Baseline in Body Weight at Week 52 Excluding Rescue Approach [ Time Frame: Baseline and Week 52 ]
    This change from baseline reflects the Week 52 body weight minus the Week 0 body weight. Participants who met glycemic rescue criteria received open-label sitagliptin glycemic rescue medication.

  3. Change From Baseline in Sitting Systolic Blood Pressure (SBP) at Week 52 Excluding Rescue Approach [ Time Frame: Baseline and Week 52 ]
    This change from baseline reflects the Week 52 SBP minus the Week 0 SBP. Participants who met glycemic rescue criteria received open-label sitagliptin glycemic rescue medication.
