U.S. Net Product Revenue of $31.1 Million, Representing 53% Growth –

ANN ARBOR, Mich., November 7, 2024 (GLOBE NEWSWIRE) – Esperion (NASDAQ: ESPR) today reported financial results for the third quarter ended September 30, 2024, and provided a business update.

“The year to date has been transformational for Esperion. We successfully expanded our product labels, scaled up our commercial team and launched new indications, which have driven double-digit prescription growth every quarter since receiving the new outcome labels. In addition, we substantially strengthened our balance sheet by monetizing the European royalties on our bempedoic acid product sales and allocated the proceeds for the early, discounted payoff and termination of a previous revenue interest facility,” stated Sheldon Koenig, President and CEO of Esperion. “We are confident the advances we made in the third quarter with contracted payers and our innovative outreach to healthcare providers has strengthened our foundation for future growth as we continue to build a sustainable biopharmaceutical company and deliver preventative and life-saving medicines to patients worldwide.”

“We continue to be impressed with and encouraged by the strong adoption and growing product revenue our European partner, Daichi Sankyo Europe (DSE), is generating across Europe bringing the LDL-C lowering benefits of NILEMDO® (bempedoic acid) and NUSTENDI® (bempedoic acid and ezetimibe) to patients at risk for cardiovascular events and expect these successes to be a proxy for the substantial market opportunity in the U.S.,” added Koenig. “We also have a significant market opportunity in Japan where our partner, Otsuka Pharmaceutical, is advancing toward filing for regulatory approval of our bempedoic acid product by the end of 2024 with approval and pricing anticipated in 2025.”

•Updated utilization management criteria for over 165 million lives now aligned to our new labels across Commercial, Medicare and Medicaid payers.

◦New additions to Medicare formularies at Optum/United AARP and CVS/SilverScript coupled with Humana provides access to more than 65% of Medicare insured lives and more than 92% of commercially insured lives.

•With key restrictions and access barriers reduced, including prior authorization in some cases, physicians can now prescribe NEXLETOL® (bempedoic acid) and NEXLIZET ® (bempedoic acid and ezetimibe) with increased confidence, positioning the products for higher sales growth in the upcoming quarters and beyond.

•As a result of the combined marketing, managed care and sales initiatives, the Company achieved approximately 18% growth in new to brand prescription and increased total retail prescription equivalents by approximately 12% compared to the second quarter, and now has more than 23,500 healthcare practitioners in Q3 2024 writing scripts for NEXLETOL and NEXLIZET.

◦Building on this foundation, the fourth quarter has shown continued strength as October 2024 total retail prescription equivalents grew 17% and new to brand prescriptions increased 20% compared with the first four weeks of the third quarter of 2024.

•DSE continued to drive significant prescription growth in Europe during the third quarter, as reflected in the approximately 19% sequential increase in royalty revenue to $8.9 million based on European sales of NILEMDO and NUSTENDI.

•Otsuka Pharmaceutical remains on track to file a New Drug Application (NDA) in Japan by the end of the year, with approval and National Health Insurance (NHI) pricing anticipated in 2025.

•Daichi Sankyo Limited, Co., our partner for certain Asian regions, received regulatory approval to market NILEMDO in Taiwan.

•New Drug Applications in Canada are planned for November 2024, with potential submissions and/or partnerships in Australia and Israel expected in the first half of 2025.

•Announced a bolus of data in support of the benefits of bempedoic acid to reduce LDL-C and cardiovascular risk will be presented at the upcoming American Heart Association Scientific Sessions taking place from November 16-18, 2024, in Chicago. The following data will be presented:

▪An oral, featured presentation in the Late Breaker/Featured Science track titled “Bempedoic Acid and Limb Outcomes in Statin-Intolerant Patients with Peripheral Artery Disease: New insights from the CLEAR Outcomes Trial” explores the impact of bempedoic acid on reduction of major adverse limb events in patients with peripheral artery disease;

▪A poster presentation titled, “Statin Intolerance due to Muscle Symptoms Affects Management of Patients: Insights from the CLEAR Outcomes Trial,” evaluated whether there were differences in statin intolerance symptom history and whether this influenced the clinical course during the CLEAR Outcomes study;

▪A poster presentation titled, “Liver Steatosis and Liver Fibrosis Predict Major Adverse Cardiovascular Events in the CLEAR Outcomes Trial,” evaluates whether liver steatosis or liver fibrosis are associated with cardiovascular (CV) outcomes in CLEAR Outcomes, and if so, whether bempedoic acid treatment reduces observed increases in CV risk; and

▪A poster presentation titled, “Effectiveness of Lipid-lowering Therapy with Bempedoic Acid plus Ezetimibe in a Real-world Cohort,” evaluates the effectiveness of bempedoic acid and ezetimibe on LDL-C reduction below 100 mg/dL using real-world data.

•Continued to publish a growing body of clinical and scientific data in support of the cardiovascular risk reduction benefits of bempedoic acid.

▪DSE reported final, two-year, real-world results from the MILOS German cohort at DGK Herztage 2024 in Hamburg, Germany. The data demonstrated a strong increase in the achievement of LDL-C goals with the addition of bempedoic acid.

NEXLIZET and NEXLETOL are indicated:

•The bempedoic acid component of NEXLIZET and NEXLETOL is indicated to reduce the risk of myocardial infarction and coronary revascularization in adults who are unable to take recommended statin therapy (including those not taking a statin) with:

◦established cardiovascular disease (CVD), or

◦at high risk for a CVD event but without established CVD.

•As an adjunct to diet:

◦NEXLIZET, alone or in combination with other LDL-C lowering therapies, to reduce LDL-C in adults with primary hyperlipidemia, including HeFH.

◦NEXLETOL, in combination with other LDL-C lowering therapies, or alone when concomitant LDL-C lowering therapy is not possible, to reduce LDL-C in adults with primary hyperlipidemia, including HeFH.

NEXLIZET and NEXLETOL are contraindicated in patients with a prior hypersensitivity to bempedoic acid or ezetimibe or any of the excipients. Serious hypersensitivity reactions including anaphylaxis, angioedema, rash, and urticaria have been reported.

Hyperuricemia: Bempedoic acid, a component of NEXLIZET and NEXLETOL, may increase blood uric acid levels, which may lead to gout. Hyperuricemia may occur early in treatment and persist throughout treatment, returning to baseline following discontinuation of treatment. 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, a component of NEXLIZET and NEXLETOL, is associated with an increased risk of tendon rupture or injury. Tendon rupture may occur more frequently in patients over 60 years of age, in those taking corticosteroid or fluoroquinolone drugs, in patients with renal failure, and in patients with previous tendon disorders. Discontinue NEXLIZET or NEXLETOL at the first sign of tendon rupture. Consider alternative therapy in patients who have a history of tendon disorders or tendon rupture.

The most common adverse reactions in the primary hyperlipidemia trials of bempedoic acid, a component of NEXLIZET and NEXLETOL, in ≥2% of patients and greater than placebo were upper respiratory tract infection, muscle spasms, hyperuricemia, back pain, abdominal pain or discomfort, bronchitis, pain in extremity, anemia, and elevated liver enzymes.

Adverse reactions reported in ≥2% of patients treated with ezetimibe (a component of NEXLIZET) and at an incidence greater than placebo in clinical trials were upper respiratory tract infection, diarrhea, arthralgia, sinusitis, pain in extremity, fatigue, and influenza.

In the primary hyperlipidemia trials of NEXLIZET, the most commonly reported adverse reactions (incidence ≥3% and greater than placebo) observed with NEXLIZET, but not observed in clinical trials of bempedoic acid or ezetimibe, were urinary tract infection, nasopharyngitis, and constipation.

The most common adverse reactions in the cardiovascular outcomes trial for bempedoic acid, a component of NEXLIZET and NEXLETOL, at an incidence of ≥2% and 0.5% greater than placebo were hyperuricemia, renal impairment, anemia, elevated liver enzymes, muscle spasms, gout, and cholelithiasis.

Discontinue NEXLIZET or NEXLETOL when pregnancy is recognized unless the benefits of therapy outweigh the potential risks to the fetus. Because of the potential for serious adverse reactions in a breast-fed infant, breastfeeding is not recommended during treatment with NEXLIZET or NEXLETOL.

Report pregnancies to Esperion Therapeutics, Inc. Adverse Event reporting line at 1-833-377-7633.
