Esperion Locks in Long-Term Exclusivity for NEXLETOL and NEXLIZET with Key Patent Settlement

Settlement Pushes Generic Entry to 2040—What This Means for Esperion’s Revenue Outlook

Esperion Therapeutics took a major step in protecting its commercial future, announcing a settlement with Dr. Reddy’s Laboratories that will block U.S. generics of NEXLETOL (bempedoic acid) and NEXLIZET (bempedoic acid and ezetimibe) until at least April 19, 2040—except for some narrow, industry-standard exceptions. This effectively ends a patent litigation initiated after Dr. Reddy’s filed to market copycat drugs years ahead of Esperion’s patents expiring.

Ongoing Litigation Leaves Minor Uncertainty, but Major Patent Risk Cleared

The new agreement follows similar settlements earlier this year with Micro Labs, Hetero USA, and Accord Healthcare. After this deal, there are no active challenges to the central bempedoic acid patent (U.S. Patent No. 7,335,799, expiring December 2030), further strengthening Esperion’s hold. Several secondary patents remain in litigation, set to expire between 2036 and 2040, but the immediate risk of generic competition has receded substantially. Only a handful of lawsuits continue against other filers—including Alkem, Aurobindo, MSN, Renata, and Sandoz—with uncertain timelines.

Implications: Multi-Year Market Exclusivity Can Support Growth and Investment

With generics likely barred from the market until at least 2040, Esperion secures a valuable runway to capitalize on NEXLETOL and NEXLIZET. These oral, non-statin cholesterol-lowering medicines—supported by robust outcomes trial data—address a sizable unmet need for patients at risk of cardiovascular disease. For investors, extended exclusivity could boost long-term revenue projections, allowing Esperion to fund pipeline innovation and global expansion without near-term price erosion.

Takeaway: Market Entry Barrier Gives Esperion Strategic Breathing Room

For anyone tracking biotech, this settlement hands Esperion a substantial commercial edge in the U.S. heart drug space—giving it rare visibility out to 2040, absent surprises in ongoing cases. While the final resolution of pending lawsuits remains, the latest move sends a clear signal that Esperion’s patent estate can hold its ground. This exclusivity not only fortifies near-term sales, but could shape dealmaking and R&D plans for years ahead.

At a Glance: ESPR Trading Snapshot (11:16 AM)

While not all risks have vanished—legal, commercial, and regulatory hurdles remain—the extended market exclusivity window is likely to attract fresh attention from industry observers and long-term investors. It’s a clear demonstration of how effective legal strategy can shape the fortunes of an innovative pharmaceutical company.
