    Abstract:
    Colesevelam has shown efficacy in adults with type 2 diabetes mellitus (T2DM) in combination with metformin-, sulfonylurea-, or insulin-based therapy, lowering hemoglobin A1c (HbA1c) and low-density lipoprotein cholesterol levels. A study was conducted to evaluate colesevelam as monotherapy in drug-naïve patients with T2DM. In this randomized, double-blind, placebo-controlled, parallel-group study, adults with T2DM who had inadequate glycemic control (HbA1c ≥7.5% and ≤9.5%) with diet and exercise alone were randomized to receive colesevelam 3.75 g/day (n=176) or placebo (n=181) for 24 weeks. The primary efficacy variable was HbA1c at week 24. Colesevelam as compared to placebo showed significant reductions from baseline in HbA1c (-2.92 mmol/mol [0.3%]; p=0.01) and fasting plasma glucose (-10.3 mg/dl; p=0.04) at week 24 with last observation carried forward. Colesevelam also significantly reduced low-density lipoprotein cholesterol (-11.2%; p<0.0001), total cholesterol (-5.1%; p=0.0005), non-high-density lipoprotein cholesterol (-7.4%; p=0.0001), and apolipoprotein B (-6.5%; p=0.0001) and increased apolipoprotein A-I (+ 2.4%; p=0.04), and triglycerides (+ 9.7%; p=0.03). Colesevelam monotherapy resulted in statistically significant improvements in glycemic and most lipid parameters in subjects with type 2 diabetes, with no new or unexpected safety and tolerability issues. Modest reductions in HbA1c and low-density lipoprotein cholesterol levels with colesevelam further support its use in combination with other antidiabetes agents when treatment targets for these parameters are close but are not quite achieved.ClinicalTrials.gov identifier: NCT00789737.
