– Confirms Sufficient Data to Complete Phase 2 Clinical Study Enrollment and Advance to Phase 3 Studies in Both Heterozygous and Homozygous Familial Hypercholesterolemia –

– Establishes Pediatric Path Forward to Start and Complete Phase 3 Trial and Secure Additional Six-Month Patent Extension Through June 2031 –

ANN ARBOR, Mich., March 20, 2025 (GLOBE NEWSWIRE) -- Esperion (NASDAQ: ESPR) today announced that following meetings with the U.S. Food and Drug Administration (FDA), it has gained alignment on a regulatory path forward for initiating Phase 3 studies of bempedoic acid alone and in combination with ezetimibe in pediatric patients with heterozygous and homozygous familial hypercholesterolemia (HeFH and HoFH, respectively). Based on these discussions with the FDA, the Company plans to initiate Phase 3 clinical studies this year. The FDA previously granted orphan drug designation for bempedoic acid in HoFH indication.

“We are delighted to further advance the development of bempedoic acid for children with familial hypercholesterolemia (FH) and are pleased the FDA has indicated that we have adequate data to proceed into Phase 3 clinical trials,” stated Sheldon Koenig, President and CEO of Esperion. “In addition, this alignment supports our commitment to broaden the reach of our bempedoic acid products as part of our lifecycle management plan, providing the opportunity to extend our patent protection for an additional six months for these important therapies,” added Sheldon Koenig.

About CLEAR Path 2 and CLEAR Path 3 Studies
CLEAR Path 2 (in children with HeFH) and CLEAR Path 3 (in children with HoFH) are Phase 3, randomized double-blind, placebo-controlled, multicenter studies to evaluate the efficacy and safety of bempedoic acid with and without concurrent ezetimibe in children with HeFH or HoFH and LDL-C ≥130 mg/dL (3.4 mmol/L) while on protocol defined optimum dose of a statin. Each study is a 52-week design where patients will be randomized 2:1 to treatment or control for 24 weeks, followed by 28 weeks of an open-label extension period.

About Heterozygous Familial Hypercholesterolemia (HeFH) and Homozygous FH (HoFH)
HeFH and HoFH are the two types of FH, a genetic condition that causes high cholesterol from birth and if untreated leads to early, aggressive atherosclerotic cardiovascular disease. HeFH is the more common form occurring in 1 in 250 births and results from inheriting a gene that causes FH from one parent. If left untreated, cardiovascular disease can develop during middle adulthood. HoFH is the rarer form of the disease, an orphan indication, occurring in 1 in 300,000 births and results from inheriting a FH gene from both parents. HoFH results in higher cholesterol levels, which are often more difficult to treat as cardiovascular disease can begin as early as in childhood if untreated. In both HeFH and HoFH, the processing of LDL-C is disrupted due to these gene mutations, which leads to dangerously high levels of LDL-C. Both HeFH and HoFH are underdiagnosed and undertreated but with early detection and continued development of LDL-C therapies for patients starting at an early age, there is hope that patients with FH can control their LDL cholesterol and reduce their risk of cardiovascular disease.
