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

Ann Arbor, Mich., — (Globe Newswire — May 4, 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 development program updates and financial results for the first quarter ended March 31, 2017.

“With FDA having confirmed the pathway to approval for an LDL-C lowering indication for bempedoic acid, we remain on track to submit the NDA and MAA global regulatory filings by the first half of 2019. We expect to begin reporting top-line results from our global pivotal Phase 3 studies starting in the second quarter of 2018,” said Tim Mayleben, president and chief executive officer of Esperion Therapeutics. “Our near-term focus is the completion of patient enrollment in our Phase 3 LDL-C lowering efficacy studies, and later this quarter we look forward to announcing details of our clinical development and regulatory strategy for our doublet pill, the fixed dose combination of bempedoic acid and ezetimibe.”

Development Program and Company Highlights

·                  February 2017: Initiated the open-label extension study of the global pivotal Phase 3 long-term safety and tolerability study (Study 1) to collect additional safety data. All patients in the open-label extension study (1002-050) will receive bempedoic acid.

·                  March 2017:

·                  U.S. Food and Drug Administration (FDA) confirmed the ongoing global pivotal Phase 3 LDL-C lowering program is adequate to support approval for an LDL-C lowering indication for bempedoic acid;

·                  Brian A. Ference, M.D., M.Phil, M.Sc., F.A.C.C., Associate Professor of Medicine, Wayne State University School of Medicine, presented “Genetic Target Validation for ATP Citrate Lyase Inhibition,” at the American College of Cardiology 66th Annual Scientific Session;

·                  Initiated the Phase 2 triplet oral therapy study (1002-038) to further explore the complementary oral LDL-C lowering of bempedoic acid, ezetimibe and atorvastatin.

Upcoming Milestones

·                  June 2017:

·                  Announce the clinical development and regulatory pathway for the doublet pill, the fixed dose combination of bempedoic acid 180 mg and ezetimibe 10 mg (BA+EZ).

·                  2H 2017:

·                  Initiate and announce the design of a Phase 2 study of bempedoic acid added-on to a PCSK9i;

·                  Announce top-line results of the Phase 2 triplet oral therapy study (1002-038);

·                  Complete patient enrollment of the three ongoing global pivotal Phase 3 LDL-C lowering efficacy studies (Studies 2, 3 and 4);

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

2017 First Quarter Financial Results

As of March 31, 2017, cash and cash equivalents and investment securities available-for-sale totaled $207.8 million compared with $242.5 million at December 31, 2016.

Research and development expenses were $35.9 million for the first quarter of 2017, compared to $9.8 million for the comparable period 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 $5.0 million for the first quarter of 2017 and 2016. Decreases in stock-based compensation expense were offset by increases in costs to support public company operations and other costs to support our growth.

Esperion had a net loss of $40.5 million for the first quarter of 2017, compared to $14.6 million for the comparable period in 2016.

Esperion had approximately 22.6 million shares of common stock outstanding, with another 4.4 million issuable upon exercise of stock options and warrants and vesting of restricted stock units, and $2.3 million of debt outstanding as of March 31, 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 all global pivotal Phase 3 safety and efficacy studies and into early 2019.

Bempedoic Acid

With a targeted mechanism of action, bempedoic acid is a first-in-class, orally available, once-daily ACL inhibitor that reduces cholesterol biosynthesis and lowers elevated levels of 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 in more than 800 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 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 considered statin intolerant. Esperion-discovered and developed, bempedoic acid is a targeted LDL-C lowering therapy in Phase 3 development. The Company has

two Phase 3 products in development: 1) bempedoic acid (monotherapy) an oral, once-daily pill, and 2) an, oral, once-daily fixed dose combination pill of bempedoic acid and ezetimibe (BA+EZ).

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 CVD; the leading cause of death around the world. Bempedoic acid, the Company’s lead product candidate, is a targeted therapy that has been shown to significantly reduce elevated LDL-C levels in patients with hypercholesterolemia, including patients inadequately treated with current lipid-modifying therapies.
