MUNICH, Germany and ANN ARBOR, Michigan, March 14, 2019 /PRNewswire/ -- Daiichi Sankyo Europe GMbH (hereafter, 'Daiichi Sankyo') and Esperion Therapeutics announced today that results from the 2,230 patient, 52-week, Phase 3 long-term safety study of bempedoic acid were published in NEJM. The paper can be found online here [https://www.nejm.org/doi/pdf/10.1056/NEJMoa1803917].
Bempedoic acid is being developed as a convenient, once-daily, oral therapy for the treatment of patients with elevated LDL-C. Bempedoic acid and the bempedoic acid / ezetimibe combination are currently undergoing regulatory review for marketing authorisation by the European Medicines Agency (EMA). A decision is expected during the first half of 2020.
Study 1, also known as CLEAR Harmony (Cholesterol Lowering via BEmpedoic Acid, an ACL-inhibiting Regimen) is the largest study in the five Phase 3 study CLEAR research programme, designed to deliver significant evidence on the benefits of bempedoic acid in patients in need of additional LDL-C lowering. Study 1 evaluated the long-term safety, tolerability and efficacy of bempedoic acid 180 mg versus placebo in 2,230 high-risk patients with atherosclerotic cardiovascular disease (ASCVD) that are inadequately controlled with current lipid-modifying therapies, including maximally tolerated statins.
The NEJM publication highlights results from the primary endpoint of adverse event rates over 52-weeks along with key efficacy endpoints at 12-weeks, including that bempedoic acid:()
-- significantly lowered LDL-C by 18.1% (p<0.001) on background maximally
tolerated statin therapy
-- significantly reduced hsCRP, an important marker of the underlying
inflammation associated with cardiovascular disease by 22%
-- treated patients showed lower rates of new-onset or worsening of
diabetes compared with those on placebo (3.3% vs 5.4%)
-- did not lead to higher overall adverse events compared with placebo
(78.5% vs 78.7%), and the proportion of patients with reported serious
adverse events was small and similar compared with placebo (14.5% vs
-- did not lead to increased discontinuation rates due to muscle-related
adverse events of importance, myalgia and muscle weakness compared to
placebo (2.1% vs 1.9%)
-- showed fewer adjudicated major adverse cardiac events compared with
placebo (4.6% vs 5.7%)
-- was observed to be well-tolerated.
"The publication of the largest bempedoic acid study to date further confirms what leading experts have said, that bempedoic acid is well-tolerated and efficacious potential treatment option that can significantly lower LDL-C as well as reduce hsCRP. The results of this study further support Daiichi Sankyo Europe's long-term commitment to cardiovascular care," said Wolfgang Zierhut, MD, Executive Director Medical Affairs and Head Thrombosis and Cardiovascular at Daiichi Sankyo Europe.
"The latest study shows that bempedoic acid could be another addition to the arsenal of once-daily, oral cholesterol-lowering treatments available to patients. Overall, these latest studies show that not only is the treatment generally well-tolerated, being comparable with placebo but that when added to high intensity statin treatment it can help to further reduce LDL-C levels," said Professor Kausik Ray, Imperial College London's School of Public Health, who led the study. "Whilst this was not an outcomes study, the parallel paper in the same issue of the journal comparing the mechanism of cholesterol lowering with bempedoic acid with statins using genetics suggests that we can hope to expect similar benefit to statins per mmol/L lowering of LDL-C. The ongoing trial, 'CLEAR OUTCOMES', is specially testing even longer-term safety and whether this approach reduces cardiovascular disease risk in addition to lowering cholesterol."
Design of Global Pivotal Phase 3 Study 1
The 52-week, global, pivotal Phase 3 randomised, double-blind, placebo-controlled, multicenter study evaluated the long-term safety and tolerability of bempedoic acid 180 mg/day versus placebo in high-risk patients with ASCVD and/or heterozygous familial hypercholesterolemia (HeFH) with LDL-C levels of at least 70 mg/dL (1.8 mmol/L) who are inadequately controlled with current lipid-modifying therapies, including maximally tolerated statin therapy. The study was conducted at 117 sites in the U.S., Canada and Europe. A total of 2,230 patients were randomised 2:1 to receive bempedoic acid or placebo. The secondary objective was to assess the 12-week LDL-C lowering efficacy of bempedoic acid versus placebo. Tertiary objectives were to assess the effect of bempedoic acid on other lipid parameters and risk markers, including hsCRP.
An open-label extension study (1002-050) was initiated in early 2017 and is fully enrolled with 1,462 patients.
Bempedoic Acid / Ezetimibe Fixed Dose 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 fixed dose combination tablet is a 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 well tolerated combination results in a 35% lowering of LDL-C when used with maximally tolerated statins, a 43% lowering of LDL-C when used as a monotherapy, and a 34% reduction in high sensitivity C-reactive protein (hsCRP). Rates of treatment-emergent adverse events, muscle-related adverse events and discontinuations were similar in the bempedoic acid and placebo treatment groups.()
With a targeted mechanism of action, bempedoic acid is a first-in-class, complementary, oral, once-daily ATP Citrate Lyase (ACL) inhibitor that reduces cholesterol and fatty acid biosynthesis and lowers LDL-C by up-regulating the LDL receptor. Similar to statins, bempedoic acid also reduces high sensitivity C-reactive protein (hs-CRP), a key marker of inflammation associated with cardiovascular disease.() Bempedoic acid is a prodrug that requires activation by the very long-chain acyl-CoA synthetase-1 (ACSVL1). Furthermore, it was demonstrated that the absence of ACSVL1 in skeletal muscle provides a mechanistic basis for bempedoic acid to potentially avoid the myotoxicity associated with statin therapy.() Completed Phase 2 and Phase 3 studies conducted in almost 4,800 patients, and approximately 3,100 patients treated with bempedoic acid, have produced an additional 20% LDL-C lowering when used with maximally tolerated statins, up to 30% LDL-C lowering as monotherapy, 35% LDL-C lowering in combination with ezetimibe when used with maximally tolerated statins and up to 48% LDL-C lowering in combination with ezetimibe as monotherapy.() Rates of treatment-emergent adverse events, muscle-related adverse events and discontinuations were similar in the bempedoic acid and placebo treatment groups.()
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, randomised, 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% 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% of ASCVD patients who are not able to reach their LDL-C goals with statins alone, need less than a 40% 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.
The Lipid Management Company
Esperion is the Lipid Management Company passionately committed to developing and commercializing complementary, cost-effective, convenient, 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 tablet, 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.
