Pharmacodynamic effect of bempedoic acid and statin combinations: predictions from a dose-response model.

ABSTRACT:

Aims

Many patients are unable to achieve guideline-recommended LDL cholesterol (LDL-C) targets, despite taking maximally tolerated lipid-lowering therapy. Bempedoic acid, a competitive inhibitor of ATP citrate lyase, significantly lowers LDL-C with or without background statin therapy in diverse populations. Because pharmacodynamic interaction between statins and bempedoic acid is complex, a dose-response model was developed to predict LDL-C pharmacodynamics following administration of statins combined with bempedoic acid.

Methods and results

Bempedoic acid and statin dosing and LDL-C data were pooled from 14 phase 1-3 clinical studies. Dose-response models were developed for bempedoic acid monotherapy and bempedoic acid-statin combinations using previously published statin parameters. Simulations were performed using these models to predict change in LDL-C levels following treatment with bempedoic acid combined with clinically relevant doses of atorvastatin, rosuvastatin, simvastatin, and pravastatin. Dose-response models predicted that combining bempedoic acid with the lowest statin dose of commonly used statins would achieve a similar degree of LDL-C lowering as quadrupling that statin dose; for example, the predicted LDL-C lowering was 54% with atorvastatin 80 mg compared with 54% with atorvastatin 20 mg + bempedoic acid 180 mg, and 42% with simvastatin 40 mg compared with 46% with simvastatin 10 mg + bempedoic acid 180 mg.

Conclusion

These findings suggest bempedoic acid combined with lower statin doses offers similar LDL-C lowering compared with statin monotherapy at higher doses, potentially sparing patients requiring additional lipid-lowering therapies from the adverse events associated with higher statin doses.

Project description:ImportanceThe effects of bempedoic acid on cardiovascular outcomes in statin-intolerant patients without a prior cardiovascular event (primary prevention) have not been fully described.ObjectiveTo determine the effects of bempedoic acid on cardiovascular outcomes in primary prevention patients.Design, setting, and participantsThis masked, randomized clinical trial enrolled 13 970 statin-intolerant patients (enrollment December 2016 to August 2019 at 1250 centers in 32 countries), including 4206 primary prevention patients.InterventionsParticipants were randomized to oral bempedoic acid, 180 mg daily (n = 2100), or matching placebo (n = 2106).Main outcome measuresThe primary efficacy measure was the time from randomization to the first occurrence of any component of a composite of cardiovascular death, nonfatal myocardial infarction (MI), nonfatal stroke, or coronary revascularization.ResultsMean participant age was 68 years, 59% were female, and 66% had diabetes. From a mean baseline of 142.2 mg/dL, compared with placebo, bempedoic acid reduced low-density lipoprotein cholesterol levels by 30.2 mg/dL (21.3%) and high-sensitivity C-reactive protein levels by 0.56 mg/L (21.5%), from a median baseline of 2.4 mg/L. Follow-up for a median of 39.9 months was associated with a significant risk reduction for the primary end point (111 events [5.3%] vs 161 events [7.6%]; adjusted hazard ratio [HR], 0.70 [95% CI, 0.55-0.89]; P = .002) and key secondary end points, including the composite of cardiovascular death, MI, or stroke (83 events [4.0%] vs 134 events [6.4%]; HR, 0.64 [95% CI, 0.48-0.84]; P < .001); MI (29 events [1.4%] vs 47 events [2.2%]; HR, 0.61 [95% CI, 0.39-0.98]); cardiovascular death (37 events [1.8%] vs 65 events [3.1%]; HR, 0.61 [95% CI, 0.41-0.92]); and all-cause mortality (75 events [3.6%] vs 109 events [5.2%]; HR, 0.73 [95% CI, 0.54-0.98]). There was no significant effect on stroke or coronary revascularization. Adverse effects with bempedoic acid included a higher incidence of gout (2.6% vs 2.0%), cholelithiasis (2.5% vs 1.1%), and increases in serum creatinine, uric acid, and hepatic enzyme levels.ConclusionsIn a subgroup of high-risk primary prevention patients, bempedoic acid treatment was associated with reduced major cardiovascular events.Trial registrationClinicalTrials.gov Identifier: NCT02993406.

Project description:AimsThe aim of this study was to evaluate the low-density lipoprotein cholesterol lowering efficacy and safety of a bempedoic acid 180 mg and ezetimibe 10 mg fixed-dose combination in patients with hypercholesterolemia and a high risk of cardiovascular disease receiving maximally tolerated statin therapy.MethodsThis phase 3, double-blind clinical trial enrolled adult patients at high risk of cardiovascular disease due to atherosclerotic cardiovascular disease, heterozygous familial hypercholesterolemia, or multiple cardiovascular disease risk factors. Patients were randomly assigned (2:2:2:1) to treatment with the fixed-dose combination, bempedoic acid 180 mg, ezetimibe 10 mg or placebo added to stable background statin therapy for 12 weeks. The primary efficacy endpoint was the percentage change from baseline to week 12 in low-density lipoprotein cholesterol.ResultsAmong the 301 patients included in the primary analysis, the mean baseline low-density lipoprotein cholesterol level was 3.87 mmol/L (149.8 mg/dL). At week 12, the fixed-dose combination lowered low-density lipoprotein cholesterol (-36.2%) significantly more than placebo (1.8% (placebo-corrected difference -38.0%); P < 0.001), ezetimibe alone (-23.2%; P < 0.001) or bempedoic acid alone (-17.2%; P < 0.001). The fixed-dose combination lowered low-density lipoprotein cholesterol levels similarly across subgroups, including patients receiving high-intensity, other-intensity or no statin therapy. Improvements with the fixed-dose combination were also observed in secondary efficacy endpoints, including high-sensitivity C-reactive protein. In this trial, fixed-dose combination treatment had a generally similar safety profile compared with bempedoic acid, ezetimibe or placebo.ConclusionThe bempedoic acid and ezetimibe fixed-dose combination significantly lowered low-density lipoprotein cholesterol versus placebo or other oral monotherapies and had a favourable safety profile when added to maximally tolerated statin therapy in patients with hypercholesterolemia and high cardiovascular disease risk.Trial registrationClinicalTrials.gov identifier: NCT03337308.
