Aim: To examine the efficacy of 12 weeks of monthly evolocumab (EvoMab) 420 mg vs. placebo (Pbo) in lowering LDL-C in those with type 2 diabetes mellitus (T2DM) and hypercholesterolemia or mixed dyslipidemia and on statin therapy.
Methods: Patients ≥18 years with T2DM, HbA1c <10%, on stable pharmacotherapy for diabetes for ≥6 months, and taking a statin were eligible; 421 were randomized (2:1 EvoMab:Pbo) and dosed. Co-primary endpoints: mean % change in LDL-C from baseline to week 12 and mean % change in LDL-C from baseline to the mean of weeks 10 and 12. Additional measures included change in non-HDL-C, LDL-C goals, and measures of glycemic control.
Results: Mean participant age (SD) was 62 (8) years; 44% women; 77% Caucasian. In modified, intent to treat analyses (all randomized and dosed patients) EvoMab significantly reduced LDL-C and non-HDL-C vs. Pbo, and did not impact glycemic control. The incidence of AEs was comparable between EvoMab and Pbo, with no clinically meaningful differences in serious AEs. See Table.

aNo pattern in differences in serious AEs was observed. Chronic obstructive pulmonary disease was the only serious AE reported by ≥ 1% of patients in the evolocumab treatment group.

Conclusion: In statin-treated patients with T2DM and hypercholesterolemia or mixed dyslipidemia, evolocumab safely and effectively lowered LDL-C.
