Kezar Life Sciences is a clinical-stage biotechnology company focused on developing novel small molecule therapeutics for immune-mediated diseases. Its lead product candidate, zetomipzomib, is a selective immunoproteasome inhibitor being developed for autoimmune hepatitis (AIH) and lupus nephritis (LN). The company has faced challenges in aligning with the FDA on clinical trial designs for zetomipzomib in AIH, leading to a strategic review of alternatives and a restructuring plan. Previously, Kezar Life Sciences also developed KZR-261, a Sec61-based program, but ceased its development and sold the related assets in March 2026. The company relies on third-party contract manufacturing organizations for its product candidates and has entered into a collaboration and license agreement with Everest Medicines for the development and commercialization of zetomipzomib in certain Asian territories.

Revenue is primarily driven by upfront payments, milestone payments, and royalties from collaboration and license agreements, such as the agreement with Everest Medicines for zetomipzomib.
