A Study of the Safety and Efficacy of MK-0431A XR in Pediatric Participants With Type 2 Diabetes Mellitus (MK-0431A-289)
A Phase III Multicenter, Double-blind, Randomized, Placebo-controlled Clinical Trial to Evaluate the Safety and Efficacy of MK-0431A XR (a Fixed-dose Combination Tablet of Sitagliptin and Extended-release Metformin) in Pediatric Subjects With Type 2 Diabetes Mellitus With Inadequate Glycemic Control on Metformin Monotherapy

The purpose of this study is to assess the safety and efficacy of the addition of sitagliptin (administered as MK-0431A XR) compared with the addition of placebo to therapy with extended-release metformin (metformin XR) for the treatment of type 2 diabetes mellitus (T2DM) in pediatric participants with inadequate glycemic control on metformin monotherapy. The primary hypothesis is that the addition of sitagliptin reduces hemoglobin A1c (A1C) more than the addition of placebo after 20 weeks of treatment.

Phase 3
Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Type 2 Diabetes Mellitus
  • Drug: Sitagliptin + Metformin XR FDC
    Sitagliptin + Metformin XR fixed-dose combination tablet (sitagliptin/metformin: 50/500 mg, 50/1000 mg) administered with a meal, preferably in the evening
  • Drug: Placebo to Sitagliptin + Metformin XR
    Matching placebo to Sitagliptin + Metformin XR fixed-dose combination tablet administered with a meal, preferably in the evening
  • Drug: Metformin XR
    Metformin XR tablet (500 mg, 1000 mg) administered with a meal, preferably in the evening
    Other Name: Glucophage® XR
  • Drug: Placebo to metformin XR
    Matching placebo to metformin XR tablet administered with a meal, preferably in the evening
  • Drug: Insulin glargine
    The insulin regimen and dosing will be at the discretion of the investigator (based on locally accepted, national, or international guidelines for the indication and use of insulin glargine)
    Other Name: Lantus
  • Experimental: Sitagliptin + Metformin XR FDC
    Phase A: two sitagliptin + extended-release (XR) metformin fixed-dose combination (FDC) tablets (MK-0431A XR) orally daily (total daily dose: 100 mg sitagliptin and 1000, 1500 or 2000 mg metformin XR) plus two placebo to metformin XR tablets for 20 weeks. Insulin glargine may be administered as glycemic rescue therapy during Phase A of the study. Phase B: two sitagliptin + metformin XR FDC tablets orally daily (total daily dose: 100 mg sitagliptin and 1000, 1500 or 2000 mg metformin XR) plus two placebo to metformin XR tablets for 34 weeks. Insulin glargine may be administered during Phase B of the study depending on the participants' glucose and A1C levels.
    Interventions:
    • Drug: Sitagliptin + Metformin XR FDC
    • Drug: Placebo to metformin XR
    • Drug: Insulin glargine
  • Placebo Comparator: Placebo to Sitagliptin + Metformin XR FDC
    Phase A: two placebo to sitagliptin + metformin XR FDC tablets orally daily plus two metformin XR tablets (total daily dose: 1000, 1500 or 2000 mg) for 20 weeks. Insulin glargine may be administered as glycemic rescue therapy during Phase A of the study. Phase B: two placebo to sitagliptin + metformin XR FDC tablets orally daily plus two metformin XR tablets (total daily dose: 1000, 1500 or 2000 mg) for 34 weeks. Insulin glargine may be administered during Phase B of the study depending on the participants' glucose and A1C levels.
    Interventions:
    • Drug: Placebo to Sitagliptin + Metformin XR
