研究概览
简要总结
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.
详细描述
This study includes a 1-week screening period, an 8-week (or greater) antihyperglycemic agent (AHA) wash-off and/or metformin dose stable period (as necessary), a 2-week single-blind placebo run-in period, a 26-week double-blind treatment period, and a post-treatment telephone contact 14 days after the last dose of study drug.

结局指标
主要结局
Change From Baseline in A1C (%) at Week 26 (Excluding Rescue Approach)
时间窗: 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.
Percentage of Participants Experiencing An Adverse Event (AE) (Including Rescue Approach)
时间窗: Up to 28 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.
