A Study to Evaluate the Efficacy and Safety of Ertugliflozin in Asian Participants With Type 2 Diabetes and Inadequate Glycemic Control on Metformin Monotherapy (MK-8835-012)

This is a study to evaluate the efficacy and safety of the addition of ertugliflozin to metformin monotherapy in Asian participants with Type 2 diabetes mellitis (T2DM) who have inadequate glycemic control on metformin monotherapy. The primary hypothesis is that the mean reduction from baseline in HbA1C for 15 mg and 5 mg ertugliflozin (tested sequentially) is greater than for placebo.

Primary outcomes

  1. Change From Baseline in A1C (%) at Week 26 (Excluding Rescue Approach)

    Time frame: Baseline and Week 26

    A1C is blood marker used to report average blood glucose levels over prolonged periods of time. Percentage A1C is the ratio of glycated hemoglobin to total hemoglobin x 100. Thus, this change from baseline reflects the Week 26 A1C minus the Week 0 A1C (which is estimated on average for each treatment group using a constrained longitudinal data analysis model, which allows for participants with missing data to be included in the analysis). Participants who met pre-specified glycemic criteria were rescued with oral tablets of open-label glimepiride and dosed according to Investigator judgment. Per protocol, this data set excludes data for any participant after the initiation of glycemic rescue therapy.

  2. Change From Baseline in A1C (%) at Week 26 (Excluding Rescue Approach) (China Subpopulation)

    Time frame: Baseline and Week 26
