SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE) – May 12, 2021 –  Kezar Life Sciences, Inc. (Nasdaq: KZR), a clinical-stage biotechnology company discovering and developing breakthrough treatments for immune-mediated and oncologic disorders, today announced its first quarter 2021 financial results and corporate highlights.

“Last quarter saw excellent execution by the Kezar team across both of our programs. We look forward to sharing data this June from the completed Phase 1b portion of the MISSION study of KZR-616 in SLE patients, followed by an interim review of the Phase 2 portion of MISSION in LN patients in the fourth quarter. Our conviction continues to deepen that immunoproteasome inhibition has the potential to be a powerful, differentiated treatment approach for patients with autoimmune diseases,” said John Fowler, Kezar’s Co-founder and Chief Executive Officer.  “In addition, we are on track to submit an IND for KZR-261, our first-in-class protein secretion inhibitor, in mid-2021 and commence a Phase 1 study in solid tumors shortly thereafter.”

Clinical Highlights & Updates

KZR-616: Selective Immunoproteasome Inhibitor

MISSION – Phase 1b/2 clinical trial in patients with systemic lupus erythematous (SLE) and lupus nephritis (LN), respectively (NCT03393013)


The last patient from the MISSION Phase 1b completed treatment in February 2021, and final clinical data from this 25-week safety and tolerability study of up to 75 mg weekly of KZR-616 in 47 patients with SLE will be presented during the European Congress of Rheumatology (EULAR 2021) in June.



The amended Phase 2 open-label portion of the MISSION trial in patients with active, proliferative lupus nephritis opened for enrollment in August 2020 and is actively recruiting. The primary efficacy endpoint for the trial is the proportion of patients achieving a renal response measured by a 50% or greater reduction in urine protein to creatinine ratio (UPCR) at six months.



Interim data are expected in late 2021, and topline data are expected in the first half of 2022.
