Measure
MK-0893 + Sitagliptin
Participants received an initial loading dose of 200 mg MK-0893 at randomization, followed by MK-0893 administered orally as 40 mg tablets daily throughout the double-blind treatment period. Sitagliptin was administered orally as 100 mg tablets daily before the morning meal throughout the double-blind treatment period.
MK-0893 + Metformin
Participants received an initial loading dose of 200 mg MK-0893 at randomization, followed by MK-0893 orally (40 mg tablets) administered daily throughout the double-blind treatment period. Participants received Metformin orally (500 mg tablets) over an initial 2-week titration period starting at 500 mg administered twice daily before the morning and evening meals, increasing to 1500 mg daily, and ending with 1000 mg twice daily. Metformin was then administered throughout the double-blind treatment period.
Sitagliptin + Metformin
Sitagliptin was administered orally as 100 mg tablets daily before the morning meal throughout the double-blind treatment period. Participants received Metformin orally (500 mg tablets) over an initial 2-week titration period starting at 500 mg administered twice daily before the morning and evening meals, increasing to 1500 mg daily, and ending with 1000 mg twice daily. Metformin was then administered throughout the double-blind treatment period.

SECONDARY outcome

Timeframe: BL, 4 weeks (end of double-blind treatment period)

Population: Full Analysis Set Population

Glucagon-Like Peptide-1 (GLP-1) is an incretin hormone that acts as a potent insulin secretegogue in response to nutrient ingestion and stimulates glucose disposition. The total AUC of Total GLP-1 levels was calculated from blood sample data measured after the morning meal.

Population: Full Analysis Set Population

GLP-1 is cleaved from proglucagon to form the active peptide GLP-1. The active form promotes suppression of glucagon secretion. The total AUC of Active GLP-1 levels was calculated from blood sample data measured after the morning meal.
