Aim: Bempedoic acid is a novel oral drug, which has been increasingly researched to play an important role in the treatment of hypercholesterolemia recently. However, results from original studies were inconsistent and inconclusive. We aimed to conduct a meta-analysis to quantitatively appraise the efficacy and safety of bempedoic acid.
Methods: PubMed, Embase, Web of Science and Scopus were searched from inception to 30 January 2020. We included randomized controlled trials that compared the efficacy and safety of bempedoic acid with placebo in patients with hypercholesterolemia. Results from trials were presented as mean differences or odds ratios (ORs) with 95% confidence intervals (CIs) and were pooled by random or fixed effects model. The risk of bias and heterogeneity among trials were also assessed and analyzed.
Results: Pooled analysis of 10 eligible trials showed that bempedoic acid treatment resulted in greater lowering of the low-density lipoprotein cholesterol level than the placebo group (mean difference -23.16%, 95% CI -26.92% to -19.04%). We also found that improvements in lipid parameters and biomarkers were still maintained at weeks 24 and 52 from the long-term trials. As for safety, bempedoic acid did not increase the risk of overall adverse events (OR 1.02, 95% CI 0.88 to 1.18). However, the incidence of adverse events leading to discontinuation was higher in the bempedoic acid group (OR 1.44, 95% CI 1.14 to 1.82).
Conclusions: Available evidence from randomized controlled trials suggests that bempedoic acid provides a well-tolerated and effective therapeutic option for lipid lowering in patients with hyperlipidemia.
