Andre navne:
  • Januvia
  • MK-0431
Medicin: Pioglitazone
Participants taking 30 mg or more pioglitazone oral tablet(s) daily at screening in combination with metformin will enter a 4-week dose-stable period followed by a 2-week single-blind run-in and a 26-week treatment period. Participants taking 4 mg or more rosiglitazone oral tablet(s) daily at screening in combination with metformin were to be switched to a corresponding dose of pioglitazone prior to starting a 4-week dose-stable period. Participants who are taking less than 30 mg/day or no pioglitazone at screening will be titrated to a stable dose of at least 30 mg pioglitazone once daily over a maximum of 4 weeks followed by a dose-stable period of 10 weeks, a 2-week single-blind placebo run-in, and a 26-week treatment period. Total treatment with pioglitazone will be up to 42 weeks.
Andre navne:

Medicin: Metformin
Participants taking 1500 mg or more metformin oral tablet(s) and at least 30 mg pioglitazone or 4 mg rosiglitazone daily at screening will enter a 4-week dose-stable period followed by a 2-week single-blind placebo run-in, and a 26-week treatment period. Participants who are taking less than 1500 mg/day metformin at screening will be titrated to a stable dose of at least 1500 mg metformin once daily over a maximum of 4 weeks followed by a dose-stable period of 10 weeks, a 2-week single-blind placebo run-in, and a 26-week treatment period. Total treatment with metformin will be up to 42 weeks.

  • Glucotrol
Placebo komparator: Placebo
Placebo to sitagliptin orally once daily for 26 weeks.
Medicin: Pioglitazone
Participants taking 30 mg or more pioglitazone oral tablet(s) daily at screening in combination with metformin will enter a 4-week dose-stable period followed by a 2-week single-blind run-in and a 26-week treatment period.
