Four deaths lead to suspension of clinical trial for autoimmune kidney disease treatment

  • Kezar Life Sciences halts trial of lupus-nephritis treatment after four patient deaths
  • Independent data monitoring committee recommends suspension
  • Review found common pattern of symptoms and proximity to dosing in fatalities
  • Phase 2a Portola trial for autoimmune hepatitis remains active with no Grade 4 or 5 serious adverse events

Kezar Life Sciences has voluntarily suspended enrollment and dosing in a clinical trial of zetomipzomib, a treatment for lupus nephritis, following the recommendation of an independent data monitoring committee. The review assessed deaths of patients in the Philippines and Argentina. Out of 84 patients enrolled in the Palizade trial, three fatalities showed a common pattern of symptoms and proximity to dosing, along with additional non-fatal serious adverse events. Kezar Life Sciences has not observed any instances of death or serious opportunistic infections in prior clinical studies of zetomipzomib. The company is notifying study investigators and regulatory authorities, including the FDA and EMA.
