Comparison of Two Treatment Regimens (Sitagliptin Versus Liraglutide) on Participants Who Failed to Achieve Good Glucose Control on Metformin Alone (MK-0431-403)
A Phase III, Multicenter, Randomized, Open-label Clinical Trial Comparing the Efficacy and Safety of a Sitagliptin-Based Treatment Paradigm to a Liraglutide-Based Treatment Paradigm in Patients With Type 2 Diabetes Mellitus Who Have Inadequate Glycemic Control on Metformin Monotherapy
This study is being done to compare the effectiveness and safety of two treatment paradigms (oral sitagliptin with or without glimepiride versus liraglutide with or without increased dosing) for the treatment of participants with Type 2 Diabetes that is not adequately controlled with metformin alone. The primary hypothesis postulated that the mean change from baseline in hemoglobin A1c (A1C) in participants treated with a sitagliptin-based treatment is non-inferior to that of participants treated with a liraglutide-based
treatment.

Description

- History of leukemia, lymphoma, aplastic anemia, myeloproliferative or myelodysplastic diseases, thrombocytopenia, or malignant melanoma, regardless of the time since treatment.
- Pregnancy or breastfeeding, or intention to become pregnant or donate eggs within the projected duration of the study.
- Participation in another study with an investigational drug or device within 12 weeks prior to screening.
- History of hypersensitivity or any contraindication to sitagliptin, liraglutide, glimepiride, or metformin based upon the labels of the country of the investigational site.
- Participation in a weight loss program and not yet in maintenance phase, or starting of a weight loss medication (such as orlistat or phentermine) within the prior 8 weeks.
- Surgery within the prior 4 weeks or major surgery planned during the study.
- Personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN 2).

Active Comparator: Liraglutide
Liraglutide subcutaneous injection once daily for 26 weeks (starting dose 0.6 mg daily up-titrated to 1.2 mg daily on Day 8).
Participants continued their stable dose of metformin >=1500 mg orally daily.
Participants may have had their liraglutide dose uptitrated to 1.8 mg daily for glycemic control.
|
metformin tablets at a dose of ≥1500 mg per day
Other Names:
0.6 mg by subcutaneous (pen) injection, once daily, on Days 1-7; up-titrated on Day 8 to 1.2 mg daily.
At Week 12, dose may be increased to 1.8 mg once daily for participants who did not meet protocol-specified glycemic goals.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Hemoglobin A1c (A1C)
Time Frame: Baseline and Week 26
|
A1C is measured as percent.
Thus, this change from baseline reflects the Week 26 A1C percent minus the Week 0 A1C percent.

Time Frame: Baseline and Week 26
|
Change from baseline at Week 26 is defined as Week 26 minus Week 0.
