Approximately 210 participants will be randomized to receive daxdilimab or placebo administered subcutaneously through Week 52 in addition to their standard of care background therapy (mycophenolate mofetil (MMF) and corticosteroids). At Week 64, all participants will be assigned to a quarterly dosing maintenance regimen of either daxdilimab or placebo based upon pre-defined renal response observed by Week 52. The maximum trial duration per participant is approximately 116 weeks including a 4-week screening period, the 104 weeks for the treatment period where participants will receive daxdilimab or placebo, and approximately 8 weeks for the follow-up period. Safety evaluations will be performed regularly throughout the course of the study.
Phase 2, multicenter, double-blind, randomized, placebo-controlled, parallel-group trial to evaluate the efficacy and safety of daxdilimab in patients with active, proliferative lupus nephritis (LN).
