Intercept Hit With 2nd Denial on NASH Drug
FDA has issued Intercept Pharmaceuticals a second complete response letter on its NDA resubmission for obeticholic acid (OCA) for treating pre-cirrhotic fibrosis due to nonalcoholic steatohepatitis (NASH). The letter told Intercept that any NDA resubmission would require, at a minimum, successful completion of the long-term outcomes phase of the company’s REGENERATE study. The company says that based on the letter it has “decided to discontinue all NASH-related investment.”
In 2020, FDA issued the first complete response letter on the NDA and determined that the “predicted benefit of OCA based on a surrogate histopathologic endpoint remains uncertain and does not sufficiently outweigh the potential risks to support accelerated approval for the treatment of patients with liver fibrosis due to NASH,” according to the company.
Intercept said the January resubmission was supported by data from its OCA NASH clinical development program, including two positive, interim 18-month analyses from the pivotal Phase 3 REGENERATE study in patients with pre-cirrhotic liver fibrosis due to NASH. “In these analyses, OCA 25 mg consistently demonstrated double the response rate of placebo in a reduction in liver fibrosis stage without worsening of any of the three histologic components of NASH, an endpoint consistent with FDA’s draft guidance,” it said. “Further, a detailed assessment of 2,477 patients in REGENERATE, including nearly 1,000 patients on the study drug for at least four years, provides a well-characterized safety profile that is monitorable and manageable, and supports chronic administration of OCA.”
