Esperion Therapeutics Provides Clinical Development and Regulatory Update for Bempedoic Acid
ANN ARBOR, Mich., June 28, 2016 (GLOBE NEWSWIRE) -- Esperion Therapeutics, Inc. (NASDAQ:ESPR), a late-stage pharmaceutical company focused on developing and commercializing first-in-class oral therapies for the treatment of patients with elevated low density lipoprotein cholesterol (LDL-C), today provided updates on the bempedoic acid (ETC-1002) clinical development program and regulatory plans. The clinical program has two major components: the global pivotal Phase 3 efficacy and safety studies, and the planned global cardiovascular outcomes trial (CVOT) in patients with elevated LDL-C levels who are unable to tolerate statins (statin intolerance). The Company intends to initiate global pivotal Phase 3 efficacy studies for LDL-C lowering in patients with hypercholesterolemia, and a CVOT specifically in statin intolerant patients who are at high risk for cardiovascular (CV) disease, in the fourth quarter of 2016.
For Europe, the Company engaged with the European Medicines Agency (EMA) resulting in alignment on the definition of statin intolerance and key design features of the global Phase 3 LDL-C lowering program and CVOT. The planned LDL-C lowering efficacy studies, together with the ongoing long-term safety and tolerability study (1002-040) initiated in January 2016, are designed to support a submission for an LDL-C lowering Marketing Authorization Application (MAA) for bempedoic acid in patients with elevated LDL-C, including statin intolerant patients, in Europe by 2019. The CVOT is designed to support a MAA submission for bempedoic acid for CV disease risk reduction in statin intolerant patients in Europe by 2022.
For the United States (U.S.), the Company engaged with the U.S. Food and Drug Administration (FDA or the Agency) resulting in alignment on the definition of statin intolerance, key design features of the CVOT, and the regulatory approval pathway for a CV disease risk reduction indication in statin intolerant patients for bempedoic acid. However, the FDA did not provide clarity on a regulatory pathway for an LDL-C lowering indication in the U.S. in statin intolerant patients at this time. The Agency indicated its position regarding an LDL-C lowering indication could be impacted by potential future changes in their view of LDL-C lowering as a surrogate endpoint or the possibility of a shift in the future standard-of-care for statin intolerant patients with elevated LDL-C levels. In the event LDL-C lowering is no longer a surrogate endpoint for initial approval in the future, Esperion would plan to submit a New Drug Application (NDA) to FDA for a CV disease risk reduction indication on the basis of a successful completion of the CVOT, which would include the results of the LDL-C lowering efficacy studies, by 2022.>[?"We are pleased with our discussions and engagement with the FDA and EMA on the definition of statin intolerance and key design features of our planned CVOT. Scientific advice received from EMA provided clarity on the regulatory approval pathways for both an LDL-C lowering indication and a cardiovascular disease risk reduction indication in statin intolerance for bempedoic acid in Europe," said Tim Mayleben, president and chief executive officer of Esperion Therapeutics. "Following engagement with FDA on the LDL-C lowering statin intolerance program for bempedoic acid in the U.S., the regulatory pathway for an LDL-C lowering indication is not well defined at this time due to the Agency's view of a potentially evolving landscape. However, we remain confident in our ability to recruit and treat a patient population that will continue to be relevant to care in the U.S. at the time we seek approvals for bempedoic acid. We look forward to advancing our global Phase 3 and CVOT clinical programs later this year, which we anticipate will support our future global regulatory and marketing application submissions."
Esperion Global Cardiovascular Outcomes Trial
The Company intends to initiate the planned CVOT in statin intolerant patients who are at high risk for CV disease in the fourth quarter of 2016. The global CVOT — Cholesterol Lowering via BEmpedoic Acid, an ACL-inhibiting Regimen (CLEAR) Outcomes — will be conducted in cooperation with the Cleveland Clinic Coordinating Center for Clinical Research (C5Research), with Steven E. Nissen, MD, Department Chair, Cardiovascular Medicine, Cleveland Clinic, serving as study chairman.
The CLEAR Outcomes trial is a randomized, double-blind, placebo-controlled study to assess the effects of bempedoic acid in statin intolerant patients who are at high risk of CV disease. The global study is expected to enroll about 12,600 patients at up to 1,000 sites in approximately 30 countries. Patients enrolled in the study will be required to have a history of, or be at high risk for, CV disease with LDL-C levels between 100 mg/dL and 190 mg/dL despite background lipid-lowering therapy. The trial will be an event-driven study with the primary efficacy endpoint of the effect of bempedoic acid versus placebo on the risk of major adverse cardiovascular events (cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, hospitalization for unstable angina, or coronary revascularization; also referred to as "five-component MACE").
"The CLEAR Outcomes study for bempedoic acid is a critical step in identifying patients who are unable to tolerate statins," said A. Michael Lincoff, MD, Director of C5Research, Vice Chairman for Research, Department of Cardiovascular Medicine, Cleveland Clinic. "This study is a well-designed and appropriately powered cardiovascular outcomes trial in these patients. We are highly confident that we will be able to identify these patients in this outcomes study. Those of us in clinical practice see these patients frequently and we need more accessible therapeutic options for them in our treatment armamentarium. As an oral therapy which provides 30 percent LDL-C lowering as monotherapy, is well-tolerated, and can easily be combined with currently available oral LDL-C lowering therapies, we hope to learn whether bempedoic acid can benefit these patients with statin intolerance."
Esperion Global Pivotal Phase 3 LDL-C Lowering Program
In the fourth quarter of 2016, the Company plans to initiate global pivotal Phase 3 efficacy studies in patients with elevated LDL-C levels, including statin intolerant patients. The global Phase 3 LDL-C lowering program is anticipated to include approximately 2,000 patients on optimized background lipid-modifying therapy with LDL-C levels of ≥130 mg/dL for patients without atherosclerotic cardiovascular disease (ASCVD) and ≥100 mg/dL for patients with ASCVD or heterozygous familial hypercholesterolemia (HeFH).
The global pivotal Phase 3 efficacy studies are expected to measure the change in LDL-C from baseline at 12 and 24 weeks. This program is also designed to produce 52 weeks of safety data, comprising an appropriately sized safety database at the time of initial MAA submission for the LDL-C lowering indication in Europe by 2019.
About Bempedoic Acid
Bempedoic acid is a first-in-class ACL inhibitor inhibiting cholesterol biosynthesis and works to lower elevated levels of LDL-C by up-regulating the LDL receptor, but with reduced potential for muscle-related side effects. Phase 1 and 2 studies conducted previously in more than 700 patients treated with bempedoic acid have produced clinically relevant LDL-C lowering results of up to 30 percent as monotherapy, approximately 50 percent in combination with ezetimibe, and an incremental 24 percent when added to stable statin therapy. It is expected that bempedoic acid will provide incremental LDL-C reduction on top of currently available background lipid-regulating therapies.
Esperion's Commitment to Patients with Hypercholesterolemia
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. Esperion's mission is to provide patients and physicians with a new therapy to significantly decrease elevated levels of LDL-C, without muscle-related side effects. Esperion-discovered and developed, bempedoic acid is an oral LDL-C lowering therapy in Phase 3 development. The Company plans to develop bempedoic acid as a monotherapy as well as a fixed-dose combination with ezetimibe, with a particular focus on patients with elevated LDL-C who are unable to tolerate statin therapy. It is estimated that approximately 5-20 percent of patients who are prescribed statins are considered statin intolerant.
