Sitagliptin + Pioglitazone

Group Type EXPERIMENTAL

Sitagliptin 100 mg q.d.+ Pioglitazone 45 mg q.d.

Intervention Type DRUG

Patients will receive combination therapy with blinded sitagliptin 100 mg q.d. (q.d. = once daily) and open-label pioglitazone 45 mg q.d. during the up to 30 week extension study. Sitagliptin 100 mg q.d. and pioglitazone 45 mg q.d. will be administered as oral tablets.

Metformin

Intervention Type DRUG

Patients not meeting specific glycemic goals during the 30-week extension study will receive open-label metformin at a dose determined by the investigator.

Pioglitazone + Placebo

Group Type ACTIVE_COMPARATOR

Pioglitazone 45 mg q.d. + Sitagliptin 100 mg placebo q.d.

Intervention Type DRUG

Patients will receive placebo to match sitagliptin 100 mg q.d. (blinded) and open-label pioglitazone 45 mg q.d. during the up to 30 week extension study. The placebo to match sitagliptin 100 mg q.d. (blinded) and open-label pioglitazone 45 mg q.d. will be administered as oral tablets.

Metformin

Intervention Type DRUG

Patients not meeting specific glycemic goals during the 30-week extension study will receive open-label metformin at a dose determined by the investigator.
