Esperion Announces Publication of Phase 3 Data for Bempedoic Acid in the Journal of Clinical Lipidology

ANN ARBOR, Mich., April 13, 2022 (GLOBE NEWSWIRE) -- Esperion (NASDAQ: ESPR) today announced the publication of data from a pooled analysis of patients enrolled in four Phase 3 bempedoic acid studies in the Journal of Clinical Lipidology.

The paper, “Efficacy and safety of bempedoic acid in patients not receiving statins in phase 3 clinical trials,” discussed a pooled analysis of data from patients enrolled in four Phase 3 bempedoic acid studies, 12 to 52 weeks in duration, who were not taking concomitant statins (n=394), and a Phase 3 bempedoic acid plus ezetimibe fixed-dose combination study (n=33). The objective of the studies was to assess the LDL-C lowering effect of bempedoic acid in patients not taking statins measured as percent change in LDL-C from baseline to week 12.

“Although statins are the mainstay of lipid-lowering treatment, 1 out of 5 individuals with a clinical indication for statin therapy are unable to take a daily statin because of side effectsⁱ and more than half (45–70%) of patients discontinue their statin therapy within 1–2 years after initiationⁱⁱ,” said JoAnne Foody, M.D., FACC, FAHA, chief medical officer of Esperion. “The results from this pooled analysis evaluating bempedoic acid monotherapy and a fixed-dose combination with ezetimibe in patients not taking statins suggest that bempedoic acid could be an effective and generally well-tolerated option for these patients, but further study is warranted. Esperion’s ongoing global CLEAR Outcomes trial, evaluating the effects of bempedoic acid on statin-intolerant patients, will expand the existing body of knowledge on lipid management for this underserved patient group and offer key insights into managing LDL-C without the use of statins.”

The results of the analysis demonstrated that in patients with hypercholesterolemia who are unable to take statins, bempedoic acid monotherapy resulted in a 26.5% mean reduction in LDL-C (p<0.001) versus placebo and a fixed-dose combination of bempedoic acid with ezetimibe resulted in a 39.2% mean reduction in LDL-C versus placebo, significantly greater than with bempedoic acid or ezetimibe alone (p<0.001). Therapy was generally well-tolerated by patients and any muscle-related disorders were comparable to those observed in the placebo group. Treatment-emergent adverse events leading to discontinuation of study drug occurred at a rate of 32.8 per 100 Patient Years (PY) and 24.3 per 100 PYs with bempedoic acid and placebo, respectively. The most common reason for discontinuation of study drug was myalgia with an incidence of 5.8 per 100 PY for patients treated with bempedoic acid and 10.6 per 100 PY for patients receiving placebo.

Please see Important Safety information for Bempedoic Acid (Nexletol) and Bempedoic Acid plus Ezetimibe (Nexlizet) below.

INDICATION

NEXLETOL and NEXLIZET are indicated as adjuncts to diet and maximally tolerated statin therapy for the treatment of adults with heterozygous familial hypercholesterolemia or established atherosclerotic cardiovascular disease who require additional lowering of LDL-C. Limitations of Use: The effect of NEXLETOL and NEXLIZET on cardiovascular morbidity and mortality has not been determined.

IMPORTANT SAFETY INFORMATION

Contraindications: NEXLETOL has no contraindications. NEXLIZET is contraindicated in patients with a known hypersensitivity to ezetimibe tablets. Hypersensitivity reactions including anaphylaxis, angioedema, rash, and urticaria have been reported with ezetimibe.

Warnings and Precautions: Hyperuricemia: Bempedoic acid, a component of NEXLETOL and NEXLIZET, may increase blood uric acid levels. Hyperuricemia may occur early in treatment and persist throughout treatment, and may lead to the development of gout, especially in patients with a history of gout. Assess uric acid levels periodically as clinically indicated. Monitor for signs and symptoms of hyperuricemia, and initiate treatment with urate-lowering drugs as appropriate.

Tendon Rupture: Bempedoic acid is associated with an increased risk of tendon rupture or injury. In clinical trials, tendon rupture occurred in 0.5% of patients treated with bempedoic acid versus 0% of patients treated with placebo, and involved the rotator cuff (the shoulder), biceps tendon, or Achilles tendon. Tendon rupture occurred within weeks to months of starting bempedoic acid. Tendon rupture may occur more frequently in patients over 60 years of age, patients taking corticosteroid or fluoroquinolone drugs, patients with renal failure, and patients with previous tendon disorders. Discontinue NEXLETOL or NEXLIZET at the first sign of tendon rupture. Avoid NEXLETOL and NEXLIZET in patients who have a history of tendon disorders or tendon rupture.

Adverse Reactions: In NEXLETOL clinical trials, the most commonly reported adverse reactions were upper respiratory tract infection, muscle spasms, hyperuricemia, back pain, abdominal pain or discomfort, bronchitis, pain in extremity, anemia, and elevated liver enzymes. Reactions reported less frequently, but still more often than with placebo, included benign prostatic hyperplasia and atrial fibrillation.

In the NEXLIZET clinical trial, the most commonly reported adverse reactions observed with NEXLIZET, but not observed in clinical trials of bempedoic acid or ezetimibe, a component of NEXLIZET, and occurring more frequently than with placebo, were urinary tract infection, nasopharyngitis, and constipation.

Adverse reactions reported in clinical trials of ezetimibe, and occurring at an incidence greater than with placebo, included upper respiratory tract infection, diarrhea, arthralgia, sinusitis, pain in extremity, fatigue, and influenza. Other adverse reactions reported in postmarketing use of ezetimibe included hypersensitivity reactions, including anaphylaxis, angioedema, rash, and urticaria; erythema multiforme; myalgia; elevated creatine phosphokinase; myopathy/rhabdomyolysis; elevations in liver transaminases; hepatitis; abdominal pain; thrombocytopenia; pancreatitis; nausea; dizziness; paresthesia; depression; headache; cholelithiasis; cholecystitis.

Drug Interactions: Simvastatin and Pravastatin: Concomitant use with bempedoic acid results in increased concentrations and increased risk of simvastatin or pravastatin-related myopathy. Use of either NEXLETOL or NEXLIZET with greater than 20 mg of simvastatin or 40 mg of pravastatin should be avoided.

Cyclosporine: Caution should be exercised when using NEXLIZET and cyclosporine concomitantly due to increased exposure to both ezetimibe and cyclosporine. Monitor cyclosporine concentrations in patients receiving NEXLIZET and cyclosporine. In patients treated with cyclosporine, the potential effects of the increased exposure to ezetimibe from concomitant use should be carefully weighed against the benefits of alterations in lipid levels provided by NEXLIZET.

Fibrates: Coadministration of NEXLIZET with fibrates other than fenofibrate is not recommended. Fenofibrate and ezetimibe may increase cholesterol excretion into the bile, leading to cholelithiasis. If cholelithiasis is suspected in a patient receiving NEXLIZET and fenofibrate, gallbladder studies are indicated and alternative lipid-lowering therapy should be considered.

Cholestyramine: Concomitant use of NEXLIZET and cholestyramine decreases ezetimibe concentration. This may result in a reduction of efficacy. Administer NEXLIZET either at least 2 hours before, or at least 4 hours after, bile acid sequestrants.

Lactation and Pregnancy: It is not recommended that NEXLETOL or NEXLIZET be taken during breastfeeding. Discontinue NEXLETOL or NEXLIZET when pregnancy is recognized, unless the benefits of therapy outweigh the potential risks to the fetus. Based on the mechanism of action of bempedoic acid, NEXLETOL and NEXLIZET may cause fetal harm.
