  Purpose

This trial will evaluate the efficacy and safety of ertugliflozin monotherapy in the treatment of subjects 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 hypothesis of the trial is that at Week 26, the mean reduction from baseline in hemoglobin A1c (HbA1c) for 15 mg ertugliflozin is greater than that for placebo.

Primary Purpose: Treatment
Official Title: A Phase 3, Randomized, Double-blind, Placebo-controlled, 26-week Multicenter Study With a 26-Week Extension to Evaluate the Efficacy and Safety of Ertugliflozin Monotherapy in the Treatment of Subjects With Type 2 Diabetes Mellitus and Inadequate Glycemic Control Despite Diet and Exercise
