Cytokines 2020 and SITC presentations to showcase Sec61 inhibition as a novel mechanism for blocking expression of therapeutically relevant targets such as cytokines and immune checkpoints

SAN FRANCISCO--()--Kezar Life Sciences, Inc. (Nasdaq: KZR), a clinical-stage biotechnology company discovering and developing breakthrough treatments for immune-mediated and oncologic disorders, today announced six presentations during four upcoming medical and scientific conferences.

“The growing body of data around KZR-616, our first-in-class selective immunoproteasome inhibitor, support its unique and powerful immunomodulatory mechanism to tackle severe immune-mediated diseases where treatment options are limited,” said Noreen Henig, MD, Kezar’s Chief Medical Officer.

“We’re thrilled to highlight our Protein Secretion Drug Discovery program as a novel way to target immune checkpoints in oncology and cytokine pathways in inflammatory disorders,” said Christopher Kirk, PhD, Kezar’s President and Chief Scientific Officer. “Our novel compounds highlight the potential of targeting the protein secretion pathway and the Sec61 translocon, as a means to induce inhibition of multiple therapeutically relevant targets.”

Following is an overview of Kezar’s upcoming scientific and clinical presentations, which will also be made available on the company’s website:

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 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 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 protein secretion pathways. KZR-261 is a broad-spectrum anti-tumor agent that acts through direct interaction and inhibition of Sec61 activity. The compound was discovered at Kezar through a robust medicinal chemistry campaign in which several scaffolds were progressed through the company’s proprietary platform evaluating Sec61 modulation. As a result, Kezar has established a broad library of protein secretion inhibitors. KZR-261 has demonstrated several encouraging properties that lead to its potential to be an anti-cancer agent for the treatment of solid and hematologic malignancies. IND-enabling activities are currently underway, and an IND submission in solid tumors is expected to be filed in the first quarter of 2021.

About Kezar Life Sciences

Based in South San Francisco, Kezar Life Sciences is combining courage, conviction and cutting-edge science to develop 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 and inhibit multiple drivers of disease via a single target. KZR-616, a first-in-class selective immunoproteasome inhibitor, is being evaluated in severe and underserved autoimmune diseases. Additionally, KZR-261, the first clinical candidate for the treatment of cancer from the company's protein secretion program targeting the Sec61 translocon, is undergoing IND-enabling activities.
