ANN ARBOR, Mich., March 27, 2018 (GLOBE NEWSWIRE) -- Esperion (NASDAQ:ESPR), the Lipid Management Company focused on developing and commercializing complementary, convenient, cost-effective, once-daily, oral therapies for the treatment of patients with elevated low density lipoprotein cholesterol (LDL-C), today announced positive top-line results from the Phase 2 clinical study (1002-039) that evaluated the LDL-C lowering efficacy and safety of bempedoic acid 180 mg added-on to stable background therapy of a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor in 58 patients with hypercholesterolemia.
The eight-week study met its primary endpoint with additional LDL-C lowering totaling 30 percent (p<0.001). The LDL-C lowering for the bempedoic acid group was 27 percent from baseline, as compared to an increase of three percent for the placebo group. Patients treated with bempedoic acid also achieved a significantly greater reduction of 34 percent in high-sensitivity C-reactive protein (hsCRP), an important marker of the underlying inflammation associated with cardiovascular disease, compared to the placebo group which had a reduction of two percent (p<0.029).

"Bempedoic acid has previously demonstrated the ability to complement currently available standard-of-care oral LDL-C lowering therapies, and the results of this Phase 2 study show that bempedoic acid can also be safely and effectively used in patients who require additional LDL-C lowering despite taking an injectable PCSK9 inhibitor," said Tim M. Mayleben, president and chief executive officer of Esperion. "These Phase 2 results provide consistent evidence and further support that bempedoic acid is poised to become the broadly accessible, complementary, once-daily, oral LDL-C lowering therapy that is appealing to patients, physicians and payers."
In this study, bempedoic acid was observed to be safe and well-tolerated. There were essentially no differences in the occurrence of adverse events (AEs) between the bempedoic acid and placebo groups, serious adverse events or muscle-related AEs. There were no discontinuations due to AEs or muscle-related AEs. No patients in either group had elevations in liver function tests (ALT/AST) of greater than three times the upper limit of normal, repeated and confirmed. The cumulative number of patients now treated with bempedoic acid in completed Phase 2 and Phase 3 clinical trials totals 947. Of these, six patients (0.63 percent) had elevations in liver function tests. This rate of elevations in liver function tests is consistent with the rate observed in previous clinical trials and with all other previously approved oral LDL-C-lowering therapies, including statins and ezetimibe.

Design of Phase 2 Study 1002-039
This eight-week Phase 2, randomized, double-blind, placebo-controlled, multicenter study evaluated the efficacy and safety of bempedoic acid 180 mg/day in patients with hypercholesterolemia at screening (LDL-C ≥ 160 mg/dL) who then received 12 weeks of background injectable evolocumab 420 mg administered every four weeks prior to randomization. A total of 59 patients from 21 sites in the U.S. and Canada were then randomized 1:1 to receive bempedoic acid or placebo added-on to evolocumab. The primary efficacy objective was to assess the eight-week LDL-C lowering efficacy of bempedoic acid versus placebo in patients on a PCSK9 inhibitor. Secondary objectives included evaluating the safety and tolerability of bempedoic acid versus placebo and its effects on other risk markers, including hsCRP.

About Esperion's Global Pivotal Phase 3 LDL-C Lowering Program
Esperion initiated its global, pivotal, Phase 3 clinical development program in January 2016 to evaluate the safety, tolerability and consistent, complementary LDL-C-lowering efficacy of bempedoic acid and the bempedoic acid / ezetimibe combination pill in patients with atherosclerotic cardiovascular disease (ASCVD), or who are at a high risk for ASCVD, with hypercholesterolemia who continue to have elevated levels of LDL-C despite the use of maximally-tolerated statins and ezetimibe, leaving them at high risk for cardiovascular events. The program includes five studies in approximately 4,000 patients, four for bempedoic acid and one for the bempedoic acid / ezetimibe combination pill.
Esperion plans to submit New Drug Applications (NDAs) to the U.S. Food and Drug Administration (FDA) for bempedoic acid and the bempedoic acid / ezetimibe combination pill for LDL-C-lowering indications by the first quarter of 2019. Additionally, Esperion plans to submit Marketing Authorization Applications (MAAs) to the European Medicines Agency (EMA) by the second quarter of 2019.
About Bempedoic Acid
With a targeted mechanism of action, bempedoic acid is a first-in-class, complementary, orally available, once-daily ATP Citrate Lyase (ACL) inhibitor that reduces cholesterol biosynthesis and lowers LDL-C by up-regulating the LDL receptor. Similar to statins, bempedoic acid also reduces hsCRP, a key marker of inflammation associated with cardiovascular disease. Completed Phase 1, Phase 2 and Phase 3 studies conducted in approximately 1,600 patients, and close to 1,000 patients treated with bempedoic acid, have produced LDL-C lowering results of up to 30 percent as monotherapy, approximately 50 percent in combination with ezetimibe and an incremental 20+ percent when added to stable statin therapy.
The effect of bempedoic acid on cardiovascular morbidity and mortality has not yet been determined.
Esperion's Commitment to Patients with Hypercholesterolemia
High levels of LDL-C can lead to a build-up of fat and cholesterol in and on artery walls (known as atherosclerosis), potentially leading to cardiovascular events, including heart attack or stroke. In the U.S., 78 million people, or more than 20 percent of the population, have elevated LDL-C; an additional 73 million people in Europe and 30 million people in Japan also live with elevated LDL-C. There are approximately 13 million people in the U.S. with atherosclerotic cardiovascular disease (ASCVD) who live with elevated levels of LDL-C despite taking maximally-tolerated lipid-modifying therapy — including individuals considered statin intolerant — leaving them at high risk for cardiovascular events. The vast majority of these patients, 9.5 million, require less than 30 percent additional LDL-C lowering to achieve treatment goals.
Esperion's mission as the Lipid Management Company is to deliver once-daily, oral therapies that complement existing oral drugs to provide the additional LDL-C lowering that these patients need.
The Lipid Management Company
Esperion is the Lipid Management Company passionately committed to developing and commercializing convenient, complementary, cost-effective, once-daily, oral therapies for the treatment of patients with elevated LDL-C. Through scientific and clinical excellence, and a deep understanding of cholesterol biology, the experienced lipid management team at Esperion is committed to developing new LDL-C lowering therapies that will make a substantial impact on reducing global cardiovascular disease; the leading cause of death around the world. Bempedoic acid and the company's lead product candidate, the bempedoic acid / ezetimibe combination pill, are targeted therapies that have been shown to significantly lower elevated LDL-C levels in patients with hypercholesterolemia, including patients inadequately treated with current lipid-modifying therapies.
