Colesevelam oral suspension will be studied as treatment of type 2 diabetes mellitus (T2DM) to evaluate clinical safety and efficacy in patients aged 10-17 years. The patients may have been treated with Metformin or have had no antidiabetic drug treatment in the previous three months.

Study Hypothesis: Colesevelam oral suspension for pediatric subjects with T2DM is safe, well tolerated, and shows improved blood sugar control (as evidenced by a significant change from baseline in hemoglobin A1C [HbA1c]).

Condition Intervention Phase
Type 2 Diabetes Mellitus
Drug: Welchol for oral suspension placebo proxy
Drug: Welchol for oral suspension
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: Colesevelam Oral Suspension as Monotherapy or Add-on to Metformin Therapy in Pediatric Subjects With Type 2 Diabetes Mellitus

Primary Outcome Measures:
  • mean change in hemoglobin A1c from baseline (day 1) to 6 months [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • mean change in fasting plasma glucose from baseline (day 1) to 6 months [ Time Frame: 6 months ]
  • percentage of subjects with HbA1c decreasing >= 0.7% from baseline (day 1) to 6 months [ Time Frame: 6 months ]
  • percentage of subjects with final HbA1c < 7.0% at 6 months [ Time Frame: 6 months ]
  • percentage of subjects with decrease in fasting plasma glucose >= 30 mg/dL from baseline (day 1) to 6 months [ Time Frame: 6 months ]
  • mean change in plasma lipids from baseline (day 1) to 6 months [ Time Frame: 6 months ]
    To assess the effects of colesevelam HCl oral suspension on changes in plasma lipids including total cholesterol (TC), low-density lipoprotein cholesterol, (LDL-C), high-density lipoprotein cholesterol (HDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), triglycerides (TG), apolipoprotein A-1 (apo A-1), and apolipoprotein B (apo B).
