Brief summary

To evaluate the effect of colesevelam on LDL levels and A1c in high-risk , dysglycemic South Asians (with diabetes, and/or with CAD and concomitant metabolic syndrome) whose LDL remains above target despite optimal statin use.

Detailed description

This is a prospective, non-controlled, open label, multicenter trial of colesevelam in Canadian South Asian adults at high cardiovascular risk. 1. 15-20 clinical sites from Ontario, Quebec, Manitoba and British Columbia will be selected from CCRN's network of primary care physicians and cardiologists to identify patients having stable type 2 diabetes or documented stable CAD with metabolic syndrome who are on maximally tolerated statin therapy, with LDL \>2.0 mmol/L or non-HDL \> 2.6 mmol/L. 2. Following informed consent, patients will be screened at baseline for HbA1c, fasting blood glucose, lipid profile, renal function and liver enzymes. 3. Baseline demographics, CAD and diabetes documentation and concurrent drug therapy will be collected. 4. 250 eligible patients will receive a physician prescription of colesevelam (Lodalis) 625 mg tablets (3 tablets taken twice daily) for 24 weeks. 5. Physicians will be requested not to change lipid or diabetes therapy over the 24 week course of the trial. 6. Patients will be contacted at 2 and 12 weeks (visit 3 and 4) via a phone call to assess adherence to the prescribed therapy, review other concurrent medications and assess for any adverse events. 7. The week 24 visit (study visit 5) will include collection of fasting blood work as per screening visit, review of concurrent drug therapy and a final assessment for any adverse events.

Design outcomes

Primary

MeasureTime frame
The % difference in LDL between baseline and end of study6 months

Secondary

MeasureTime frame
The % change in HbA1c levels between baseline and end of study6 months
The absolute change in LDL and non-HDL levels between baseline and end of study6 months
The safety and tolerability of colesevelam will be determined by the patient reported side/adverse effects and/or hospitalization related to Colesevelam. The side effects will be captured at Visit 3, 4 and 5.6 months
