Efficacy and Safety of Alirocumab in Diabetes Mellitus

Alirocumab did not significantly affect blood glucose in individuals with or without diabetes.

Alirocumab significantly lowered the low-density lipoprotein cholesterol levels of patients with and without diabetes without altering blood glucose levels and with similar rates of adverse reactions as those reported by placebo groups, according to a study published in Diabetes Therapy.

This subgroup analysis of 5 separate phase 3, placebo-controlled studies compared the safety and efficacy of alirocumab for patients with and without diabetes, with the primary end point goal being the reduction of low-density lipoprotein cholesterol from baseline to week 24. Of the 2416 patients treated with alirocumab, 30.1% had been diagnosed with diabetes at baseline, compared with 30.2% of patients in the placebo group.

Analyses showed that most individuals achieved <70 mg/dL of cholesterol after 24 weeks of alirocumab treatment, regardless of whether or not they had diabetes. Treatment with 75 mg alirocumab every 2 weeks resulted in 68.3% of individuals with diabetes reaching this end point goal, compared with 65.8% of individuals without diabetes. Treatment with 150 mg alirocumab every 2 weeks resulted in 78% of individuals with diabetes reaching this goal compared with 77% of individuals without diabetes.

Compared with 82% of individuals with diabetes in the placebo groups and 81% of individuals without diabetes in the placebo groups, 80% of individuals both with diabetes and without diabetes experienced adverse reactions with alirocumab treatment. Adverse reactions reported were also similar.
