• Allocation: Randomized
• Intervention Model: Parallel Assignment
• Masking: Double (Participant, Investigator)
• Primary Purpose: Treatment
• Official Title: A Multicenter, Randomized, Double-Blind Study to Evaluate the Safety and Efficacy of the Addition of MK0431 to Patients With Type 2 Diabetes Mellitus Who Have Inadequate Glycemic Control on Pioglitazone Therapy

Arms and Interventions

Arm	Intervention/treatment
Active Comparator: Sitagliptin 100 mg; Sitagliptin 100 mg	Drug: Comparator: Sitagliptin; Sitagliptin 100 mg once daily, from Visit 4 through Visit 8. Day 1 through week 24; Other Name: Januvia; Drug: Comparator: Pioglitazone; Pioglitazone 30 mg or 45 mg once daily, Visit 2 through Visit 8; Other Name: ACTOS; Drug: Metformin; Metformin rescue for patients meeting pre-specified glycemic criteria. Metformin 500 mg,once daily, Visit 4 through Visit 8
Placebo Comparator: Placebo; Placebo	Drug: Comparator: Placebo; Placebo (to match Sitagliptin 100 mg) once daily, from Visit 4 through Visit 8. Day 1 through Week 24; Drug: Comparator: Pioglitazone; Pioglitazone 30 mg or 45 mg once daily, Visit 2 through Visit 8; Other Name: ACTOS; Drug: Metformin; Metformin rescue for patients meeting pre-specified glycemic criteria. Metformin 500 mg,once daily, Visit 4 through Visit 8

Outcome Measures

Primary Outcome Measures :

1. Change From Baseline in HbA1c (Hemoglobin A1C) at Week 24 [ Time Frame: Baseline and week 24 ]
   HbA1c is measured as a percent. Thus, this change from baseline reflects the Week 24 HbA1c percent minus the Week 0 HbA1c percent.

Secondary Outcome Measures :

1. Change From Baseline in FPG (Fasting Plasma Glucose) at Week 24 [ Time Frame: Baseline and week 24 ]
   Change from baseline at Week 24 is defined as Week 24 minus Week 0.
