Clinical Trial: PORTOLA


Autoimmune Hepatitis (AIH)


PORTOLA is a randomized, double-blind, placebo-controlled phase 2a study with an open-label extension to evaluate the safety and efficacy of zetomipzomib (KZR-616) in people living with autoimmune hepatitis (AIH). Zetomipzomib is a first-in-class, investigational product being studied for the treatment of autoimmune diseases, including autoimmune hepatitis, a rare and chronic autoimmune liver disease. Zetomipzomib acts by inhibiting the immunoproteasome, a structure found in immune cells that helps to regulate the normal functioning of the immune system.
