Esperion Provides Bempedoic Acid Franchise Development Program Updates; Reports Second Quarter 2017 Financial Results

— Phase 3 Enrollment Progress Supports NDA Submissions for LDL-C Lowering Indications for Bempedoic Acid / Ezetimibe Combination Pill and Bempedoic Acid by the First Quarter 2019 —

— Conference Call and Webcast on Tuesday, August 8, 2017 at 8:30 a.m. Eastern Time —

Ann Arbor, Mich., — (Globe Newswire — August 8, 2017) — Esperion Therapeutics, Inc. (NASDAQ: ESPR), the Lipid Management Company focused on developing and commercializing convenient, complementary, cost-effective, once-daily, oral therapies for the treatment of patients with elevated low density lipoprotein cholesterol (LDL-C), today provided bempedoic acid franchise development program updates, and financial results for the second quarter ended June 30, 2017. The company now expects to submit two New Drug Applications (NDAs) for LDL-C lowering indications for the bempedoic acid / ezetimibe combination pill and bempedoic acid by the first quarter of 2019.

Bempedoic Acid Global Pivotal Phase 3 Program Update

The ongoing Phase 3 program for bempedoic acid includes four global pivotal studies expected to enroll approximately 3,400 high CVD risk patients with hypercholesterolemia and atherosclerotic cardiovascular disease (ASCVD) and/or heterozygous familial hypercholesterolemia (HeFH), or who are high risk primary prevention, on optimized background lipid-modifying therapy and with elevated levels of LDL-C. These patients are on two distinct types of background lipid-modifying therapy: 1) patients on their maximally tolerated statin therapy, and 2) patients only able to tolerate less than the lowest approved daily starting dose (e.g., patients considered statin intolerant).

Global Pivotal Phase 3 Study 1: This 52-week long-term safety and tolerability study was initiated in January 2016 and fully enrolled in January 2017 with 2,230 patients with ASCVD and/or HeFH whose LDL-C is not adequately controlled with current lipid-modifying therapies, and who are taking maximally tolerated statin therapy. Top-line results are expected to be announced by the second quarter of 2018.

Global Pivotal Phase 3 Study 2: This 52-week LDL-C lowering efficacy and safety study was initiated in December 2016 and will be fully enrolled mid-month with approximately 750 patients with ASCVD and/or HeFH whose LDL-C is not adequately controlled with current lipid-modifying therapies, and who are taking maximally tolerated statin therapy. Top-line results are expected to be announced by the third quarter of 2018.

Global Pivotal Phase 3 Study 3: This 24-week LDL-C lowering efficacy study was initiated in December 2016 and will be fully enrolled this month with approximately 300 high CVD risk patients with ASCVD and/or HeFH, or who are high risk primary prevention, whose LDL-C is not adequately controlled with current lipid-modifying therapies, and who are only able to tolerate less than the lowest approved daily starting dose of a statin and considered statin intolerant. Top-line results are expected to be announced by the second quarter of 2018.

Global Pivotal Phase 3 Study 4: This 12-week LDL-C lowering efficacy study was initiated in December 2016 and will be fully enrolled in September with approximately 225 high CVD risk patients with ASCVD and/or HeFH, whose LDL-C is not adequately controlled with current lipid-modifying therapies, including ezetimibe, and who are only able to tolerate the lowest approved daily starting dose of a statin and considered statin intolerant. Top-line results are expected to be announced by the second quarter of 2018.

“I’m pleased with the progress our team has made enrolling patients in all of our global pivotal Phase 3 LDL-C lowering efficacy studies. We are on track to complete enrollment for the Phase 3 program this quarter, and look forward to reporting top-line results from each of the four global pivotal Phase 3 studies in the second and third quarters of 2018,” said Tim Mayleben, president and chief executive officer of Esperion Therapeutics. “The Phase 3 pivotal study enrollment progress, together with FDA confirmation of the regulatory pathways to approval for both the bempedoic acid / ezetimibe combination pill and bempedoic acid supports our plans to submit both NDAs for LDL-C lowering indications by the first quarter of 2019.”

Development Program and Company Highlights

·                  May 2017: Mary McGowan, M.D., Chief Medical Officer, presented “Bempedoic Acid Reduces LDL-C and is Well-Tolerated in Patients Receiving Atorvastatin 80 mg Background Therapy” at the 2017 National Lipid Association Scientific Sessions.

·                  June 2017: The U.S. Food and Drug Administration (FDA) confirmed the abbreviated 505(b)(2) regulatory pathway to approval for the bempedoic acid / ezetimibe combination pill for an LDL-C lowering indication. The pivotal Phase 3 bridging study is expected to be initiated in the fourth quarter of 2017 and complete by the end of 2018 to support an NDA submission for an LDL-C lowering indication.

·                  July 2017: Initiated and announced the design of a Phase 2 study of bempedoic acid added-on to a PCSK9i.

·                  August 2017: Announced positive top-line results of Phase 2 study (1002-038) of the bempedoic acid / ezetimibe combination + atorvastatin oral therapy.

Upcoming Milestones

·                  Q4 2017:

·                  Initiate and announce design of the bempedoic acid / ezetimibe combination pill global pivotal Phase 3 bridging study;

·                  Dr. Brian A. Ference to publish in a top-tier medical journal results from Mendelian randomization studies that genetically validate ACL inhibition.

2017 Second Quarter Financial Results

As of June 30, 2017, cash and cash equivalents and investment securities available-for-sale totaled $181.1 million compared with $242.5 million at December 31, 2016.

Research and development expenses were $38.2 million for the second quarter of 2017 and $74.1 million for the six months ended June 30, 2017, compared to $9.7 million and $19.5 million for the comparable periods in 2016. The increase in research and development expenses was primarily related to the further clinical development of bempedoic acid, including costs to support the global pivotal Phase 3 LDL-C lowering program and the cardiovascular outcomes trial (CVOT), and further increases in our headcount and stock-based compensation expense.

General and administrative expenses were $5.4 million for the second quarter of 2017 and $10.4 million for the six months ended June 30, 2017, compared to $4.6 million and $9.7 million for the comparable periods in 2016. The increase in general and administrative expenses was primarily attributable to costs to support public company operations, increases in our headcount, and other costs to support our growth.

Esperion had a net loss of $43.3 million for the second quarter of 2017 and $83.9 million for the six months ended June 30, 2017, compared to $14.0 million and $28.6 million, respectively, for the comparable period in 2016.

Esperion had approximately 22.6 million shares of common stock outstanding, with another 4.6 million issuable upon exercise of stock options and warrants and vesting of restricted stock units, and $1.9 million of debt outstanding as of June 30, 2017.

2017 Financial Outlook

Esperion expects full-year 2017 net cash used in operating activities to be approximately $125 to $135 million and its cash and cash equivalents and investment securities to be approximately $105 to $115 million at December 31, 2017. The Company estimates that current cash resources are sufficient to fund operations through the announcement of top-line results from our global pivotal Phase 3 programs for the bempedoic acid / ezetimibe combination pill and bempedoic acid and into early 2019.

Bempedoic Acid / Ezetimibe Combination

Through the complementary mechanisms of action of inhibition of cholesterol synthesis (bempedoic acid) and inhibition of cholesterol absorption (ezetimibe), the bempedoic acid / ezetimibe combination pill 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 LDL receptors. Previously completed Phase 2 data demonstrated that this safe and well tolerated combination results in a 48 percent lowering of LDL-C, a 26 percent reduction in high sensitivity C-reactive protein (hsCRP), and may potentially be associated with a lower occurrence of muscle-related side effects.

Bempedoic Acid

With a targeted mechanism of action, bempedoic acid is a first-in-class, complementary, orally available, once-daily ACL inhibitor that reduces cholesterol biosynthesis and lowers LDL-C by up-regulating the LDL receptor, and may potentially be associated with a lower occurrence of muscle-related side effects. Completed Phase 1 and 2 studies conducted in more than 1,000 patients and over 800 patients treated with bempedoic acid have produced clinically relevant LDL-C lowering results of up to 30 percent as monotherapy and an incremental 20+ percent when added to stable statin therapy.

Esperion’s Commitment to Patients with Hypercholesterolemia

In the United States, 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 as the Lipid Management Company is to provide patients and physicians with convenient, complementary, cost-effective, once-daily, oral therapies to significantly reduce elevated levels of LDL-C in patients inadequately treated with current lipid-modifying therapies. It is estimated that 40 million patients in the U.S. are taking statins with approximately 5-20 percent of these patients only able to tolerate less than the lowest approved daily starting dose of their statin and are therefore considered to be statin intolerant. Esperion-discovered and developed, bempedoic acid is a targeted LDL-C lowering therapy in Phase 3

development. The company has two convenient, cost-effective, complementary, orally available, LDL-C lowering therapies in Phase 3 development: 1) a once-daily, oral bempedoic acid / ezetimibe combination pill, and 2) bempedoic acid, a once-daily, oral pill.

The Lipid Management Company

Esperion Therapeutics, Inc. 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 reduce elevated LDL-C levels in patients with hypercholesterolemia, including patients inadequately treated with current lipid-modifying therapies.
