Item 8.01. Other Events.

As previously disclosed, in March and April 2024, Esperion Therapeutics, Inc. (“Esperion”) received notice letters from nine pharmaceutical companies, six of which filed exclusively with respect to NEXLETOL® (bempedoic acid) Tablet and three of which filed with respect to NEXLETOL and NEXLIZET® (bempedoic acid and ezetimibe) Tablet (each, an “ANDA Filer”), notifying Esperion that each company had filed an Abbreviated New Drug Application (“ANDA”) with the U.S. Food and Drug Administration (“FDA”) seeking approval of a generic version of NEXLETOL and/or NEXLIZET in the United States, as applicable.

On May 8, 2024, Esperion filed a patent infringement lawsuit under the Hatch-Waxman Act in the United States District Court, District of New Jersey, against Micro Labs USA Inc. (along with an affiliate), an ANDA Filer with respect to NEXLETOL. Esperion’s complaint alleges that by filing the applicable ANDA, such ANDA Filer has infringed NEXLETOL’s Orange Book patents included in its Paragraph IV certifications, and seek an injunction preventing FDA from granting final approval of the ANDA before the expiration of the asserted patents, and a permanent injunction to prevent the ANDA Filer from commercializing a generic version of NEXLETOL until the expiration of the asserted patents. Esperion intends to file similar patent infringement lawsuits under the Hatch-Waxman Act against the other ANDA Filers with respect to NEXLETOL and/or NEXLIZET, as applicable.

The ANDAs each contained Paragraph IV certifications alleging that certain of Esperion’s Orange Book listed patents covering NEXLETOL or NEXLIZET, as applicable, are invalid and/or will not be infringed by each ANDA Filer’s manufacture, use or sale of the medicine for which the ANDA was submitted.

Esperion intends to vigorously defend its intellectual property. The filing of the lawsuit within 45 days of receipt of the notice letter from the applicable ANDA filer triggered a stay of FDA approval of such ANDA for up to 30 months following the expiry of the New Chemical Entity exclusivity in accordance with the U.S. Drug Price Competition and Patent Term Restoration Act of 1984 (the “Hatch-Waxman Act”).
