ANN ARBOR, Mich., May 04, 2021 (GLOBE NEWSWIRE) -- ESPERION (NASDAQ:ESPR), the lipid management company, today reported financial results for the first quarter ended March 31, 2021 and provided a business update.

“In the first quarter our team was focused on driving new prescription growth and executing on strategic initiatives that will enhance our ability to bring our medicines to as many patients as possible. This includes improving Medicare Part D coverage and positioning for NEXLETOL^® and NEXLIZET^®, as well as building our scientific, health economics and outcomes research platform, all while ensuring our landmark CLEAR cardiovascular outcomes trial remains on track for the second half of 2022,” said Tim M. Mayleben, president and chief executive officer of ESPERION. “The first quarter was a challenging period, but we are encouraged by both our refined product positioning and data indicating that patients are returning to their physician offices, which together are expected to translate into accelerated prescription growth in the second half of the year. Our momentum has continued in the early days of the second quarter as we expanded key agreements with Daiichi Sankyo and Oberland Capital, adding $80 million in cash to the balance sheet while deepening our relationships with these committed and collaborative partners.”

First Quarter 2021 Financial Results

Total revenue for the first quarter ended March 31, 2021 was $8.0 million compared to $1.8 million for the first quarter of 2020. U.S. product revenue for the first quarter ended March 31, 2021 was $6.4 million, compared to $0.9 million for the comparable period in 2020. Royalty revenue for the first quarter ended March 31, 2021 was $0.6 million. The increase in total revenue was primarily due to NEXLETOL and NEXLIZET being available for sale during the entire first quarter of 2021. NEXLETOL and NEXLIZET became commercially available in the U.S. on March 30, 2020 and June 4, 2020, respectively.

Research and development expenses were $28.0 million for the first quarter of 2021, compared to $34.7 million for the comparable period in 2020. The decrease in expense during the first quarter was primarily attributable to a decline in manufacturing costs which were previously classified as research and development expense prior to FDA approval of NEXLETOL and NEXLIZET in the first quarter of 2020.

Selling, general and administrative expenses were $61.1 million for the first quarter of 2021, compared to $41.6 million for the comparable period in 2020. The increase in expense was primarily attributable to salaries and benefits from the build out of our customer-facing team and other costs to support the commercialization of NEXLETOL and NEXLIZET in the U.S, as well as a $13.3 million one-time charge associated with a legal settlement.

ESPERION had a net loss of $90.9 million for the first quarter of 2021, compared to a net loss of $78.2 million for the comparable period in 2020. ESPERION had a basic and diluted net loss per share of $3.50 for the first quarter of 2021, compared to $2.84 for the comparable period in 2020.

As of March 31, 2021, cash, cash equivalents and investment securities available-for-sale totaled $217.9 million compared with $305.0 million at December 31, 2020. This amount does not include the $30 million upfront payment resulting from the expanded Daiichi Sankyo collaboration partnership or the $50 million third and final tranche from Oberland Capital.

ESPERION ended the quarter with approximately 26.2 million shares of common stock outstanding, excluding the 2.0 million treasury shares to be purchased in the prepaid forward transaction as part of the convertible debt financing with another 4.7 million issuable upon exercise of stock options and vesting of restricted stock units.

2021 Financial Outlook

Esperion’s pro-forma cash balance as of March 31, 2021 was $297.9 million as a result of the $30 million upfront payment from Daiichi Sankyo and the $50 million payment from Oberland Capital to be received in May 2021.

Research and development expenses for the full year 2021 are expected to be $120 million to $130 million. Selling, general and administrative expenses for the full year 2021 are expected to be $200 million to $210 million.

ESPERION continues to expect full-year 2021 operating expenses to be approximately $320 million to $340 million, inclusive of $30 million of non-cash, stock-based compensation.

CLEAR Cardiovascular Outcomes Trial

The effect of bempedoic acid on cardiovascular morbidity and mortality has not been determined. ESPERION 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 are considered "statin averse." The CVOT — known as CLEAR Cardiovascular Outcomes Trial — is an event-driven, global, randomized, double-blind, placebo-controlled study that completed enrollment in August 2019 of over 14,000 patients with hypercholesterolemia and high CVD risk at over 1,200 sites in 32 countries.

ESPERION Therapeutics’ Commitment to Patients with Hyperlipidemia

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 and 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. living with elevated levels of LDL-C despite taking maximally tolerated lipid-modifying therapy — including individuals considered statin averse — leaving them at high risk for cardiovascular events¹. In the United States, more than 50 percent of atherosclerotic cardiovascular disease (ASCVD) patients and heterozygous familial hypercholesterolemia (HeFH) patients who are not able to reach their guideline recommended LDL-C levels with statins alone need less than a 40 percent reduction to reach their LDL-C threshold goal².

ESPERION's mission as the Lipid Management Company is to deliver oral, once-daily medicines that complement existing oral drugs to provide the additional LDL-C lowering that these patients need.
