Bempedoic acid in patients with type 2 diabetes mellitus, prediabetes, and normoglycaemia: A post hoc analysis of efficacy and glycaemic control using pooled data from phase 3 clinical trials

AIM: To evaluate the effect of bempedoic acid on glycaemic and lipid variables in patients with hypercholesterolaemia. METHODS: A patient‐level pooled analysis of four phase 3, randomized, double‐blind, placebo‐controlled trials evaluated changes in glycaemia, change from baseline in LDL‐C, and adverse events. Patients (N = 3621) on maximally tolerated statins were randomized 2:1 to oral bempedoic acid 180 mg or placebo once daily for 12 to 52 weeks with the results analysed by baseline glycaemic status (diabetes, prediabetes, or normoglycaemia). RESULTS: The annual rate of new‐onset diabetes for bempedoic acid versus placebo in patients with normoglycaemia at baseline (n = 618) was 0.3% versus 0.8%, and for patients with prediabetes at baseline (n = 1868) it was 4.7% versus 5.9%. In patients with diabetes or prediabetes, bempedoic acid significantly (P < .0001) reduced HbA1c by −0.12% and −0.06%, respectively, and did not worsen fasting glucose versus placebo. Bempedoic acid significantly and consistently lowered LDL‐C levels versus placebo, regardless of baseline glycaemic status (placebo‐corrected difference range, −17.2% to −29.6%; P < .001 for each stratum). The safety of bempedoic acid was comparable with placebo and similar across glycaemic strata. CONCLUSIONS: Bempedoic acid significantly lowered LDL‐C across glycaemic strata and did not worsen glycaemic variables or increase the incidence of new‐onset diabetes versus placebo over a median follow‐up of 1 year.
