  Purpose
This study will evaluate the lipid-lowering effect and safety of colesevelam therapy administered to heterozygous familial pediatric patients 10 through 17 years of age who are on a stable dose of a pediatric-approved statin monotherapy (atorvastatin, lovastatin, simvastatin or pravastatin), or who are treatment naive to lipid-lowering therapy.

Condition Intervention Phase
Hypercholesterolemia Drug: colesevelam HCl Drug: placebo Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: Randomized, Double-blind, Placebo-controlled Efficacy and Safety Study of Colesevelam HCl Administered to Pediatric Patients With Heterozygous Familial Hypercholesterolemia on a Stable Dose of Statins or Treatment Naive to Lipid-lowering Therapy

Primary Outcome Measures:
  • Percent Change in Plasma Low Density Lipoprotein-cholesterol (LDL-C) From Day 1 (Study Baseline) to Week 8. [ Time Frame: 8 weeks (week 8 - day 1) ]
    Percent change in LDL-C (mg/dL) and standard deviation (SD) from Day 1 (Study Baseline)to Week 8 (last observation carried forward - LOCF)- Intent-to-Treat ITT population.


Secondary Outcome Measures:
  • Percent Change in Plasma Total Cholesterol (TC) From Day 1 (Study Baseline) to Week 8. [ Time Frame: 8 weeks (week 8 - day 1) ]
    Percent change in total cholesterol (mg/dL) and standard deviation (SD) from Day 1 (Study Baseline) to Week 8 (last observation carried forward - LOCF)- Intent-to-Treat ITT population.

  • Percent Change in Plasma Triglycerides (TG) From Day 1 (Study Baseline) to Week 8. [ Time Frame: 8 weeks (week 8 - day 1) ]
    Percent change in triglycerides (mg/dL) and standard deviation (SD) from Day 1 (Study Baseline) to Week 8 (last observation carried forward - LOCF)- Intent-to-Treat ITT population.

  • Percent Change in Plasma High-density Lipoprotein-cholesterol (HDL-C) From Day 1 (Study Baseline) to Week 8. [ Time Frame: 8 weeks (week 8 - day 1) ]
    Percent change in HDL-C (mg/dL) and standard deviation (SD) from Day 1 (Study Baseline) to Week 8 (last observation carried forward - LOCF)- Intent-to-Treat ITT population.

  • Percent Change in Plasma Non-high Density Lipoprotein-cholesterol (Non-HDL-C) From Day 1 (Study Baseline) to Week 8. [ Time Frame: 8 weeks (week 8 - day 1) ]
    Percent change in non-HDL-C (mg/dL) and standard deviation (SD) from Day 1 (Study Baseline) to Week 8 (last observation carried forward - LOCF)- Intent-to-Treat ITT population.

  • Percent Change in Plasma Apolipoprotien A-I (Apo A-1) From Day 1 (Study Baseline) to Week 8. [ Time Frame: 8 weeks (week 8 - day 1) ]
    Percent change in Apolipoprotien A-I (Apo A-1) (mg/dL) and standard deviation (SD) from Day 1 (Study Baseline) to Week 8 (last observation carried forward - LOCF)- Intent-to-Treat ITT population.

  • Percent Change in Plasma Apolipoprotein B (Apo B) From Day 1 (Study Baseline) to Week 8. [ Time Frame: 8 weeks (week 8 - day 1) ]
    Percent change in Apo B (mg/dL) and standard deviation (SD) from Day 1 (Study Baseline) to Week 8 (last observation carried forward - LOCF)- Intent-to-Treat ITT population.

  • Percent Change in Low-density Lipoprotein Cholesterol (LDL-C) From Study Baseline (Day 1) to Week 26. [ Time Frame: 26 weeks (week 26 - day 1) ]
    Percent change in low-density lipoprotein cholesterol from baseline to Week 26 was calculated for subpopulations representing each assigned treatment group during the Double blind Period, and for the overall population in the Open Label Extension Period.

  • Percent Change in Total Cholesterol From Study Baseline (Day 1) to Week 26. [ Time Frame: 26 weeks (week 26 - day 1) ]
    Percent change in total cholesterol (TC) from baseline to Week 26 was calculated for subpopulations representing each assigned treatment group during the Double blind Period, and for the overall population in the Open Label Extension Period.

  • Percent Change in Triglycerides From Study Baseline (Day 1) to Week 26. [ Time Frame: 26 weeks (week 26 - day 1) ]
    Percent change in triglycerides from baseline to Week 26 was calculated for subpopulations representing each assigned treatment group during the Double blind Period, and for the overall population in the Open Label Extension Period.

  • Percent Change in High-density Lipoprotein Cholesterol (HDL-C) From Study Baseline (Day 1) to Week 26. [ Time Frame: 26 weeks (week 26 - day 1) ]
    Percent change in high-density lipoprotein cholesterol from baseline to Week 26 was calculated for subpopulations representing each assigned treatment group during the Double blind Period, and for the overall population in the Open Label Extension Period.

    Percent change in non-high-density lipoprotein cholesterol from baseline to Week 26 was calculated for subpopulations representing each assigned treatment group during the Double blind Period, and for the overall population in the Open Label Extension Period.

  • Percent Change in Apolipoprotein A-I From Study Baseline (Day 1) to Week 26. [ Time Frame: 26 weeks (week 26 - day 1) ]
    Percent change in apolipoprotein A-I from baseline to Week 26 was calculated for subpopulations representing each assigned treatment group during the Double blind Period, and for the overall population in the Open Label Extension Period.

  • Percent Change in Apolipoprotein B From Study Baseline (Day 1) to Week 26. [ Time Frame: 26 weeks (week 26 - day 1) ]
