Clinical Trials and Efficacy
Mechanism of Action
Colesevelam hydrochloride, marketed as WelChol, is a bile acid sequestrant that works by binding to bile acids in the intestine, preventing their reabsorption. This mechanism leads to the upregulation of cholesterol 7-alpha-hydroxylase, converting more cholesterol into bile acids, which in turn increases the production and activity of HMG-CoA reductase in the liver and the number of LDL receptors, thereby clearing more LDL cholesterol from the blood[1][3][4].
Clinical Trial Outcomes
Several clinical trials have demonstrated the efficacy of colesevelam hydrochloride in reducing serum lipid levels. Here are some key findings:
- LDL-C Reduction: Studies have shown that colesevelam hydrochloride can significantly reduce LDL-C levels. For example, a study combining colesevelam with simvastatin resulted in a 42% mean reduction in LDL-C and a 10% median increase in HDL-C[4].
- Type 2 Diabetes: In a pivotal trial involving patients with type 2 diabetes, adding colesevelam to metformin-based therapy resulted in significant reductions in A1C and LDL-C levels. Specifically, 25% of patients achieved an A1C reduction to <7%, and 37% achieved an LDL-C level <70 mg/dL[4].
- Hypercholesterolemia: Clinical trials involving patients with primary hypercholesterolemia have shown that colesevelam hydrochloride reduces total cholesterol, LDL-C, Apo B, and non-HDL-C, while increasing HDL-C when administered alone or in combination with an HMG-CoA reductase inhibitor[3].
Common Adverse Events
The most common adverse events associated with colesevelam hydrochloride include flatulence and constipation, occurring in at least 10% of the patients in clinical trials[4].
