Kezar Life Sciences Announces Acceptance of Abstract for Presentation of First in Patient Study with KZR-616 at EULAR 2019 Annual Meeting


  • Abstract highlights preliminary results from the first two cohorts of the Phase 1b portion of the MISSION Trial in patients with systemic lupus erythematosus (SLE)

  • Detailed poster with additional results will be presented during EULAR 2019 in Madrid

SOUTH SAN FRANCISCO, Calif., May 28, 2019 (GLOBE NEWSWIRE) -- Kezar Life Sciences, Inc. (Nasdaq: KZR), a clinical-stage biotechnology company discovering and developing novel small molecule therapeutics to treat unmet needs in autoimmunity and cancer, today announced that data from the first two cohorts of an open-label dose escalation trial of KZR-616 in patients with systemic lupus erythematosus (SLE) will be featured in a poster presentation at the European League Against Rheumatism (EULAR) 2019 annual meeting taking place in Madrid, Spain June 12-15.

The full abstract, which is published on EULAR’s conference website, features preliminary results from the first two cohorts of the Phase 1b portion of the MISSION trial (Modulator of the Immunoproteasome for Systemic Lupus with and without Nephritis), which is evaluating KZR-616 in patients with SLE.  Additional details regarding the trial, outcome measures, and patients enrolled will be presented at the meeting.

“Presenting our first in patient data with KZR-616, our novel selective immunoproteasome inhibitor, is an important milestone for Kezar and represents the culmination of several years of our team’s research and development efforts,” said Niti Goel, MD, FACR, Kezar’s Chief Medical Officer.  “We are encouraged by the safety, tolerability, and potential efficacy seen thus far in the MISSION trial and look forward to sharing the detailed results with the clinical and scientific community next month. The Phase 2 portion in lupus nephritis patients has commenced enrollment, and we have identified 30 and 45mg as the appropriate doses to advance in each of our Phase 2 autoimmune clinical trials. We expect to initiate trials with KZR-616 in dermatomyositis, polymyositis, autoimmune hemolytic anemia, and immune thrombocytopenia later this year.”

Abstract # FR0196: Treatment of Systemic Lupus Erythematosus Patients with the Immunoproteasome Inhibitor KZR-616: Results from the First 2 Cohorts of an Open-Label Phase 1b Dose Escalation Trial

About KZR-616

KZR-616 is a novel, first-in-class, selective immunoproteasome inhibitor with broad therapeutic potential across multiple autoimmune diseases. Nonclinical research demonstrates that selective immunoproteasome inhibition results in a broad anti-inflammatory response in animal models of several autoimmune diseases, while avoiding immunosuppression. Phase 1a clinical trial results in healthy volunteers provide evidence that KZR-616 potentially avoids adverse effects caused by currently marketed non-selective proteasome inhibitors, which we believe prevent them from being utilized as a chronic treatment in autoimmune disorders. A Phase 1b/2 trial (MISSION study) of KZR-616 in systemic lupus erythematosus (SLE) patients and lupus nephritis (LN) patients is currently underway. Phase 2 trials in dermatomyositis (DM), polymyositis (PM), autoimmune hemolytic anemia (AIHA), and immune thrombocytopenia (ITP) are expected to commence in the second half of 2019. 

About the MISSION Study

The MISSION study (NCT03393013) is a Phase 1b/2 multi-center study in which patients receive weekly subcutaneous injections of KZR-616 for 13 weeks. The study consists of 2 parts.  The Phase 1b portion is an open-label multiple dose escalation study to evaluate the safety and tolerability of KZR-616 in patients with SLE with and without nephritis.  The Phase 2 portion is a randomized, placebo-controlled, double-blind study to evaluate the safety and efficacy of KZR-616 in patients with active proliferative LN.
