Kezar Scientific Leaders to discuss Phase 1a data with KZR-616, animal model results, and new insights into immunoproteasome biology during the ACR 2017 Annual Meeting

SOUTH SAN FRANCISCO, Oct. 31, 2017 /PRNewswire/ --Kezar Life Sciences, a private, clinical-stage biopharmaceutical company developing novel small molecule therapeutics, today announced they will be presenting three abstracts as poster presentations at the 2017 ACR Annual Meeting taking place November 3-7, 2017 in San Diego.  The posters include the first public presentation of data from Kezar's Phase 1a study and new insights relating to the unique and powerful immunomodulatory role of the immunoproteasome.

"The R&D team at Kezar is looking forward to sharing detailed information on our work with the immunoproteasome and KZR-616," stated Kezar Chief Scientific Officer and President, Christopher Kirk, PhD. "We believe these new data further validate the exciting potential of KZR-616 to become a compelling new therapy across a number of unmet needs in autoimmunity." Kezar CEO John Fowler added, "I am proud of our team's excellent progress with the KZR-616 program, and grateful for the opportunity to share the favorable safety and pharmacologic data from our Phase 1a trial at ACR."

About Immunoproteasome Inhibition and KZR-616

Protein degradation is a key process in the function and survival of all mammalian cells and is mediated by the ubiquitously expressed proteasome.  Inhibitors of the proteasome, such as VELCADE™ and KYPROLIS™, are currently used to treat multiple myeloma, a plasma cell malignancy.  In cells of the immune system, such as T-cells, a unique form of the proteasome, termed the immunoproteasome, is expressed.  The immunoproteasome regulates multiple aspects of immune responses and selective inhibitors, such as KZR-616, are well tolerated and highly active in mouse models of rheumatoid arthritis, multiple sclerosis, Crohn's disease, and lupus.
