Details and patient eligibility

About

This trial will evaluate the efficacy and safety of ertugliflozin monotherapy in the treatment of participants with type 2 diabetes mellitus (T2DM) and inadequate glycemic control on diet and exercise. This trial consists of a run-in period of 3 to 11 weeks, a 26-week placebo-controlled treatment period (Phase A), and a 26-week active treatment period (Phase B). The primary hypotheses of the trial are that at Week 26, the mean reduction from baseline in hemoglobin A1c (A1C) for 15 mg ertugliflozin is greater than that for placebo and the mean reduction from baseline in A1C for 5 mg ertugliflozin is greater than that for placebo.

Ertugliflozin 5 mg/Ertugliflozin 5 mg
Experimental group
Description:
Phase A: Ertugliflozin 5 mg administered once daily for 26 weeks. Participants requiring rescue therapy will receive open-label metformin.

Placebo/Metformin
Other group
Description:
Phase A: Placebo to ertugliflozin administered once daily for 26 weeks. Participants requiring rescue therapy will receive open-label metformin. Phase B: Participants not rescued with open-label metformin in Phase A will also receive blinded metformin up to twice daily for 26 weeks in addition to placebo. Participants rescued with metformin in Phase A will continue to receive open-label metformin. Participants requiring rescue therapy during Phase B will receive open-label glimepiride.
