Bempedoic Acid Versus Statins in Primary-Prevention Patients With Suboptimal Statin Adherence: Effects on LDL-C Reduction and Tolerability

Bempedoic acid is an oral, non-statin LDL-cholesterol (LDL-C) lowering agent that inhibits ATP citrate lyase (ACL), upstream of HMG-CoA reductase (the enzyme inhibited by statins). MDPI +1 In patients with hypercholesterolemia who are unable to tolerate statins, or have sub-optimal statin adherence/tolerance, bempedoic acid has been shown to reduce LDL-C by \~20-30% (monotherapy) and more when added to other therapies (e.g., ezetimibe) (≈30-40%). PubMed * 2 medicinejournal.in * 2 In the large primary-prevention subgroup of the trial CLEAR Outcomes (statin-intolerant patients without prior cardiovascular event), bempedoic acid (180 mg daily) lowered LDL-C by \~21.3% and hs-CRP by \~21.5%. It also was associated with a significant reduction in major adverse cardiovascular events (MACE): hazard ratio 0.70 (95% CI 0.55-0.89) versus placebo over \~40 months. PubMed +1 Regarding tolerability: muscle-related adverse events appear lower compared to statins (because bempedoic acid is activated only in the liver, not in skeletal muscle) and it appears generally well tolerated, but there are signals of increased uric acid/gout, elevated hepatic enzymes, and creatinine/renal effects. MDPI +1 Comparative cardiovascular benefit (when normalized per unit LDL-C reduction) suggests that bempedoic acid may yield similar relative risk reductions as statins, though absolute LDL-C lowering is less.
