Randomized Trial Comparing Colesevelam vs. Ezetimibe

This study will enroll 200 adult patients with T2DM who are not at target for HbA1c and LDL cholesterol. Patients who are on baseline statin therapy will be randomly assigned in a 1:1 ratio to colesevelam 3.75 g daily for 24 weeks, or ezetimibe 10 mg daily for 24 weeks. If a patient has statin intolerance, they may be on a fibrate and/or niacin, or on no lipid lowering therapy. The primary efficacy objectives are

• to demonstrate that colesevelam 3.75 g daily is non-inferior to ezetimibe 10 mg daily as add-on to statin therapy for patients achieving a composite target of HbA1c (≤ 7.0%) and LDL cholesterol (≤ 2.0 mmol/L) at week 24, and
• to compare the proportion of patients achieving a composite target of HbA1c (≤ 7.0%) and LDL cholesterol (≤ 2.0 mmol/L) at week 24.

This study will also assess the primary composite outcome in a sub-group of patients on sodium/glucose cotransporter 2 inhibitor (SGLT2i) therapy.

Inclusion criteria

• Diagnosis of type 2 diabetes > 6 months
• HbA1c level between 7.1 to 10.0% (inclusive) within three months of study enrollment
• LDL cholesterol > 2.0 mmol/L within three months of study enrollment
• Receiving a stable dose of statin for a minimum of three months, which the investigator does not plan to change over the 24-week trial period. If patient has documented statin intolerance, may be on a fibrate and/or niacin, or on no lipid lowering therapy
• Stable diabetes medications for previous three months (apart from adjustment of insulin dose)
• Informed consent

Exclusion criteria

• Use of a second lipid lowering therapy other than statin within three months of study enrolment, unless on a fibrate and/or niacin if patient has statin intolerance
