Bempedoic acid is a lipid-lowering medication that works by inhibiting adenosine triphosphate citrate lyase. This inhibition reduces the production of acetyl coenzyme A (acetyl CoA), a precursor of cholesterol synthesis, which is upstream of the hydroxy-methyl-glutaryl coenzyme A reductase (rate-limiting enzyme) targeted by statins. This inhibition leads to a decrease in hepatic cholesterol synthesis and causes an upregulation of low-density lipoprotein receptors, which increases the clearance of LDL-C from the bloodstream. Bempedoic acid is a prodrug that is activated by the liver by very-long-chain acetyl CoA synthetase 1 and is not present in muscle cells.1 This mechanism minimizes the risk of muscle-related adverse effects, making it an option for patients with statin-associated muscle symptoms (SAMS).
The 2022 American College of Cardiology (ACC) Expert Consensus Decision Pathway on the Role of Nonstatin Therapies for LDL-C Lowering in the Management of Atherosclerotic Cardiovascular Disease Risk recommends treating to an LDL-C goal of <70 mg/dL for patients with DM who are at high cardiovascular (CV) risk.2 Additionally, the 2025 American Diabetes Association (ADA) Standards of Care in Diabetes recommends a target LDL-C level of <70 mg/dL for persons 40-75 years of age with DM and at least one atherosclerotic cardiovascular disease (ASCVD) risk factor.3
This patient's LDL-C level was >70 mg/dL, which was not at goal despite ezetimibe. He could not tolerate even low doses of statin due to SAMS. Bempedoic acid, due to its activation in the liver rather than in skeletal muscle, makes it a more favorable option to reduce the likelihood of muscle-related adverse effects.
The CLEAR Outcomes (Cholesterol Lowering via Bempedoic Acid, an ACL-Inhibiting Regimen) trial, which evaluated both primary- and secondary-prevention strategies, included both patients with cardiovascular disease (CVD) and those at high risk of CVD who could not tolerate statin therapy.4 The trial data support the use of bempedoic acid to improve long-term CV outcomes and reduce LDL-C levels in both patient groups.4,5
Bempedoic acid is taken orally once daily.1 This agent can be prescribed as a fixed-dose combination therapy with ezetimibe, thus not increasing the patient's pill count burden (i.e., replacing ezetimibe monotherapy with the fixed-dose combination pill). In contrast to a proprotein convertase subtilisin/kexin type 9 inhibitor (e.g., evolocumab), which requires injection, bempedoic acid meets his preference for noninjectable options.
He had a first-degree relative with an MI before 55 years of age, which is a major ASCVD risk-enhancing factor. This risk factor further justifies aggressive lipid-lowering therapy.
The mild elevation in his Cr level is not a contraindication to bempedoic acid. His history of gout is also not an absolute contraindication. However, in the CLEAR Outcomes trial data, the incidence of gout, hyperuricemia, and cholelithiasis were higher with bempedoic acid than with placebo,4 underscoring the importance of exercising caution when considering bempedoic acid for patients with those conditions. In this trial, the risk of gout was higher among patients with a history of gout. Therefore, measuring his baseline uric acid level and monitoring his levels while he is receiving bempedoic acid treatment would be recommend. The prescribing label recommends monitoring patients for signs and symptoms of hyperuricemia, and initiating treatment with urate-lowering drugs as appropriate.
His uric acid level was within the reference range and he had only a single prior episode of gout. Thus, bempedoic acid is not contraindicated.
His ezetimibe is changed to bempedoic acid/ezetimibe in fixed-dose combination and repeat laboratory studies, including lipid levels, a CMP, and uric acid levels, will be checked in 4-6 weeks after starting treatment.
