Uniquely Powerful Approaches to Tackling the Toughest Diseases

Founded in 2015 and based in South San Francisco, Kezar (pronounced “keys are”) Life Sciences is combining courage, conviction and cutting-edge science to develop breakthrough treatments for immune-mediated and oncologic disorders – with the hope of helping people overcome their disease and live a better life. We are pioneering first-in-class, small molecule therapies that harness master regulators of cellular function to inhibit multiple drivers of disease via single, powerful targets. We are translating our innovative research in protein degradation (via immunoproteasome inhibition) and protein secretion (via the Sec61 translocon) to have a significant clinical impact in the most difficult-to-treat diseases.
