Intercept Resubmits NDA for Liver Fibrosis Drug
FDA has accepted for review an Intercept Pharmaceuticals NDA resubmission for obeticholic acid (OCA) for use in treating patients with pre-cirrhotic liver fibrosis due to nonalcoholic steatohepatitis (NASH).
In 2020, FDA issued a complete response letter on the company’s NDA that was seeking accelerated approval. The letter indicated that based on data FDA had reviewed to date it was 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 says the resubmission is 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 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fibrosis stage without worsening of any of the three histologic components of NASH, an endpoint consistent with FDA’s draft guidance,” it says. “Further, a detailed assessment of 2,477 patients in REGENERATE, including nearly 1,000 patients on study drug for at least four years, provides a well-characterized safety profile that is monitorable and manageable, and supports chronic administration of OCA.”
