Key Takeaways
Esperion named ESP-2001 its new preclinical candidate for primary sclerosing cholangitis.
ESP-2001 was discovered with Evotec and has shown liver injury reduction in preclinical studies.
Esperion will hold exclusive global rights to develop and commercialize ESP-2001.
Esperion Therapeutics (ESPR - Free Report) announced that it has nominated ESP-2001, a highly specific allosteric ATP citrate lyase (“ACLY”) inhibitor, as its new preclinical development candidate for the treatment of primary sclerosing cholangitis (“PSC”).
Currently, there are no approved treatments for PSC, a rare and debilitating autoimmune liver disease.
The company plans to initiate investigational new drug (“IND”)-enabling studies for ESP-2001 and submit an IND application to the FDA, with the goal of starting clinical studies in 2026.
Shares of Esperion were up 5.2% yesterday following the announcement of the news.
Notably, ESP-2001 was discovered through the collaboration between Esperion and Evotec (EVO - Free Report) . The collaboration leveraged ESPR’s deep expertise in ACLY therapy with Evotec’s integrated drug discovery platform.
The nomination of ESP-2001 as a preclinical candidate for PSC triggered an undisclosed payment for Evotec.
Per management, ESP-2001 has consistently reduced markers of liver and bile duct injury, inflammation and fibrosis in various preclinical studies, underlining its potential to meaningfully impact the progression of PSC.
ESP-2001 could qualify for Orphan Drug and Fast Track designations from the FDA, as well as PRIME designation from the European Medicines Agency.

ESPR Aims to Diversify Beyond Cardiovascular Diseases
Esperion has two FDA-approved drugs in its commercial portfolio, Nexletol (bempedoic acid) and Nexlizet, which are approved for treating elevated LDL-C (bad cholesterol) and for cardiovascular risk reduction. Nexlizet is a combination of bempedoic acid and ezetimibe.
These two oral drugs are marketed as Nilemdo and Nustendi in ex-U.S. markets (excluding Japan, where the company has a collaboration with Otsuka Pharmaceuticals) in partnership with Daiichi Sankyo. The company records royalties on sales of its drugs in ex-U.S. markets.
Esperion records revenues from product sales and collaboration revenues, which include royalties on sales of Nilemdo/Nustendi by collaboration partners.
Net product sales of Nexletol and Nexlizet in the United States grew 42% in the first half of 2025 to $75.2 million, reflecting increased prescription growth volumes.
If successfully developed, ESP-2001 can help Esperion expand and diversify beyond cardiovascular diseases into the lucrative liver disorder space. The company retains exclusive global development and commercialization rights to ESP-2001, targeting a potential blockbuster market opportunity of over $1 billion annually.
