Masking: Double (Participant, Investigator)

Primary Outcome Measures:
  • Change From Baseline in Hemoglobin A1C (A1C) at Week 24 [ Time Frame: Baseline and Week 24 ]

    A1C is measured as a percent. Thus, this change from

    baseline reflects the Week 24 A1C percent minus the Week 0 A1C percent.



Secondary Outcome Measures:
  • Change From Baseline in Fasting Plasma Glucose (FPG) at Week 24 [ Time Frame: Baseline and Week 24 ]

    Change from baseline at Week 24 is defined as FPG at

    Week 24 minus FPG at Week 0.


  • Change From Baseline in 2-hour Post-meal Glucose (PMG) at Week 24 [ Time Frame: Baseline and Week 24 ]
    Change from baseline at Week 24 is defined as PMG at Week 24 minus PMG at Week 0.

Primary Completion Date: July 20, 2005 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Sitagliptin 100 mg
The Sitagliptin 100 mg group includes patients who were administered once-daily treatment with oral tablets of sitagliptin 100 mg during Phase A (Weeks 0-24) of the treatment period. During Phase B (Weeks 24-104) of the treatment period these patients received once-daily coadministered treatment with oral tablets of sitagliptin 100 mg and glipizide-matched placebo.
Drug: Sitagliptin (MK0431)
Sitagliptin 100 mg once daily, from Visit 4 through Final Visit, week 104
Other Names:
  • MK0431
  • sitagliptin phosphate
  • Januvia
Drug: Metformin
Metformin 1500 mg, once daily, from Visit 2 to Final Visit (Week 104)
Drug: Pioglitazone
Pioglitazone 15 mg once daily, for patients not meeting specific glycemic goals during the placebo-controlled treatment period [Phase A], from Visit 5 (Week 6) to Visit 8 (Week 24)
Other Name: ACTOS
Placebo Comparator: Placebo / Glipizide 5 mg
The Placebo/Glipizide 5 mg group includes patients who were administered once-daily treatment with oral tablets of sitagliptin-matched placebo during Phase A (Weeks 0-24) of the treatment period. During Phase B (Weeks 24-104) of the treatment period these patients received once-daily coadministered treatment with oral tablets of sitagliptin-matched placebo 100 mg and glipizide 5 mg which was allowed to be uptitrated, in a blinded fashion, to a maximum dose of 15 mg/day.
Drug: Placebo/Glipizide 5 mg
Placebo (to match Sitagliptin 100 mg) from Visit 4 through Visit 8; Glipizide 5 mg from Visit 8, week 24 to Final Visit (Week 104)
Drug: Metformin
Metformin 1500 mg, once daily, from Visit 2 to Final Visit (Week 104)
Drug: Pioglitazone
Pioglitazone 15 mg once daily, for patients not meeting specific glycemic goals during the placebo-controlled treatment period [Phase A], from Visit 5 (Week 6) to Visit 8 (Week 24)
Other Name: ACTOS
