Parikh, MD, Assistant Professor of Medicine, Nephrology, The Ohio State University Medical Center. Additionally, the Company will present an overview of their protein secretion drug discovery platform and lead candidate, KZR-261, a novel, broad-spectrum, anti-tumor agent that acts through direct interaction and inhibition of the Sec61 translocon. Details will be provided around the Phase 1 trial design, KZR-261-101, evaluating safety, tolerability, and preliminary tumor activity, as well as the tumor selection process.

Presenters:

• John Fowler, Chief Executive Officer, Co-Founder
• Noreen Roth Henig, M.D., Chief Medical Officer
• Samir V. Parikh, M.D., Assistant Professor of Medicine, Division of Nephrology, The Ohio State University Medical Center.

About KZR-616

KZR-616 is a novel, first-in-class, selective immunoproteasome inhibitor with broad therapeutic potential across multiple autoimmune diseases. Preclinical research demonstrates that selective immunoproteasome inhibition results in a broad anti-inflammatory response in animal models of several autoimmune diseases, while avoiding immunosuppression. Data generated from Phase 1a and 1b clinical trials provide evidence that KZR-616 exhibits a favorable safety and tolerability profile for development in severe, chronic autoimmune diseases. Phase 2 trials are underway in multiple severe autoimmune diseases

About KZR-261

KZR-261, a novel, first-in-class protein secretion inhibitor, is the first clinical candidate to be nominated from Kezar’s research and discovery efforts targeting the protein secretion pathway. KZR-261 is a broad-spectrum anti-tumor agent that acts through direct interaction and inhibition of Sec61 activity. The compound was discovered by Kezar through a robust medicinal chemistry campaign in which several scaffolds were progressed through the company’s proprietary platform evaluating Sec61 modulation. KZR-261 has demonstrated several encouraging properties that lead to its potential to be an anti-cancer agent, and a Phase 1 trial is underway for the treatment of solid tumor malignancies.

About Kezar Life Sciences

Kezar Life Sciences is a clinical-stage biopharmaceutical company discovering and developing breakthrough treatments for immune-mediated and oncologic disorders. The company is pioneering first-in-class, small-molecule therapies that harness master regulators of cellular function to inhibit multiple drivers of disease via single, powerful targets. KZR-616, its lead asset, is a selective immunoproteasome inhibitor being evaluated in Phase 2 clinical trials in lupus nephritis, dermatomyositis, and polymyositis. Additionally, KZR-261, is the first anti-cancer clinical candidate from the company’s platform targeting the Sec61 translocon and the protein secretion pathway. An open-label dose-escalation Phase 1 clinical trial of KZR-261 to assess safety, tolerability and preliminary tumor activity in solid tumors is underway.
