Efficacy of Colesevelam in Subjects With Type 1 Diabetes Mellitus
Completed · Not applicable · Has a placebo group
Conditions studied: Diabetes Mellitus, Type 1, Hyperlipidemias
In brief
This is a prospective, randomized, double blind, parallel, placebo controlled clinical trial evaluating the efficacy of colesevelam HCl in reducing LDL in subjects with type 1 diabetes mellitus over a 12 week treatment period. The aim is to highlight the effect of colesevelam on LDL cholesterol and glycemia in a type 1 diabetic population. The colesevelam group is anticipated to demonstrate a mean reduction in LDL by 10% compared to the placebo group, indicated by A1c and glycemic target range CGM readings.
