Ertugliflozin vs. Glimepiride in Type 2 Diabetes Mellitus (T2DM) Participants on Metformin (MK-8835-002)

March 25, 2019 updated by: Merck Sharp & Dohme LLC

A Phase III, Multicenter, Randomized, Double-Blind, Active-Comparator-Controlled Clinical Trial to Study the Safety and Efficacy of the Addition of Ertugliflozin (MK-8835/PF-04971729) Compared With the Addition of Glimepiride in Subjects With Type 2 Diabetes Mellitus Who Have Inadequate Glycemic Control on Metformin

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Baseline and Week 52
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.
Up to Week 106
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.
Up to Week 104

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Up to Week 52
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.
Baseline and Week 52
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.
