ANN ARBOR, Mich., April 01, 2019 (GLOBE NEWSWIRE) — Esperion (NASDAQ:ESPR) announced today that results from the 345 patient, 24-week, Phase 3, double-blind, placebo-controlled study of bempedoic acid (CLEAR Serenity, also known as Study 3) were published today in the Journal of the American Heart Association (JAHA). Bempedoic acid is being developed as a complementary, cost-effective, convenient, once-daily, oral therapy for the treatment of patients with elevated low-density lipoprotein cholesterol (LDL-C). Bempedoic acid and the bempedoic acid / ezetimibe combination tablet new drug applications have been submitted to the United States Food and Drug Administration, as well as are under regulatory review for marketing authorization by the European Medicines Agency.
Study 3 evaluated the efficacy, safety, and tolerability of bempedoic acid 180 mg versus placebo in 345 patients with hypercholesterolemia and considered statin intolerant (history of intolerance to at least two statins).
The JAHA publication highlights results from the primary efficacy endpoint of LDL-C lowering at 12-weeks and key secondary endpoints of safety and tolerability over 24-weeks, including that bempedoic acid (BA):
- significantly lowered LDL-cholesterol by 21 percent;
- significantly reduced high-sensitivity C-reactive protein (hsCRP), an important marker of the underlying inflammation associated with cardiovascular disease, by 25 percent;
- was observed to be safe and well-tolerated;
- did not induce muscle symptoms in statin intolerant patients compared with placebo (BA 12.8% vs placebo 16.2%);
- showed an adverse event rate of 64.1% compared with a placebo event rate of 56.8%, a serious adverse events rate of 6.0% compared with a placebo event rate of 3.6%, with no serious adverse events considered related to study medication;
- showed numerically fewer new-onset or worsening of diabetes compared with the placebo group (BA 2.1% vs 4.5% placebo);
“In the challenging group of patients with statin intolerance, CLEAR Serenity demonstrates that bempedoic acid reduced LDL- cholesterol significantly more than placebo. Patients taking bempedoic acid reported less frequent occurrences of myalgia and muscular weakness compared with placebo. These results demonstrate bempedoic acid could offer a safe and effective oral therapeutic option especially for the millions of patients needing LDL-cholesterol lowering but have difficulty tolerating statin treatment due to muscle-related side effects,” said Ulrich Laufs, MD, PhD.
“For patients who have experienced the side effects commonly attributed to statin treatment and can’t or won’t take statins, there is an urgent need to significantly lower their LDL-cholesterol and hsCRP levels. The publication of the CLEAR Serenity Study in the Journal of American Heart Association further demonstrates that bempedoic acid could be a safe and efficacious treatment option for hypercholesterolemia patients, including those patients considered statin intolerant,” said Bill Sasiela, Senior Vice President, Clinical Development at Esperion.
Design of Global Phase 3 Study 3 (1002-046, also known CLEAR Serenity)
The 24-week, global pivotal Phase 3 randomized, double-blind, placebo-controlled, multicenter study evaluated the LDL-C lowering efficacy and safety of bempedoic acid 180 mg/day versus placebo added to background lipid-modifying therapy in patients with hypercholesterolemia who are considered statin intolerant. The study was conducted at 67 sites in the U.S. and Canada. A total of 345 patients were randomized 2:1 to receive bempedoic acid or placebo. The primary efficacy objective was to assess the 12-week LDL-C lowering efficacy of bempedoic acid versus placebo. Secondary objectives included evaluating the 24-week LDL-C lowering efficacy of bempedoic acid versus placebo, the safety and tolerability of bempedoic acid versus placebo, and its effects on other risk markers after 12 weeks of treatment, including hsCRP.
Bempedoic Acid / Ezetimibe Combination Tablet
Through the complementary mechanisms of action of inhibition of cholesterol synthesis (bempedoic acid) and inhibition of cholesterol absorption (ezetimibe), the bempedoic acid / ezetimibe combination tablet is our lead, non-statin, orally available, once-daily, LDL-C lowering therapy. Inhibition of ATP Citrate Lyase (ACL) by bempedoic acid reduces cholesterol biosynthesis and lowers LDL-C by up-regulating the LDL receptor. Inhibition of Niemann-Pick C1-Like 1 (NPC1L1) by ezetimibe results in reduced absorption of cholesterol from the gastrointestinal tract, thereby reducing delivery of cholesterol to the liver, which in turn upregulates the LDL receptors. Phase 3 data demonstrated that this safe and well-tolerated combination results in a 35 percent lowering of LDL-C when used with maximally tolerated statins, a 43 percent lowering of LDL-C when used as a monotherapy, and a 34 percent reduction in high sensitivity C-reactive protein (hsCRP).
Bempedoic Acid
With a targeted mechanism of action, bempedoic acid is a first-in-class, complementary, orally available, once-daily ATP Citrate Lyase 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 2 and Phase 3 studies conducted in almost 4,800 patients, and approximately 3,100 patients treated with bempedoic acid, have demonstrated an additional 20 percent LDL-C lowering when used with maximally tolerated statins, up to 30 percent LDL-C lowering as monotherapy, 35 percent LDL-C lowering in combination with ezetimibe when used with maximally tolerated statins and up to 48 percent LDL-C lowering in combination with ezetimibe as monotherapy.
The effect of bempedoic acid on cardiovascular morbidity and mortality has not yet been determined. The company initiated a global cardiovascular outcomes trial (CVOT) to assess the effects of bempedoic acid on the occurrence of major cardiovascular events in patients with, or at high risk for, cardiovascular disease (CVD) who are only able to tolerate less than the lowest approved daily starting dose of a statin and considered “statin intolerant.” The CVOT — known as CLEAR Outcomes — is an event-driven, global, randomized, double-blind, placebo-controlled study expected to enroll approximately 12,600 patients with hypercholesterolemia and high CVD risk at over 1,000 sites in approximately 30 countries.
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., 96 million people, or more than 37 percent of the adult population have elevated LDL-C. There are approximately 18 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. More than 50 percent of ASCVD patients who are not able to reach their LDL-C goals with statins alone, need less than a 40 percent reduction to reach their LDL-C threshold.
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.
