About this trial

This is a randomized, double-blind, parallel-controlled, multicenter, phase III study to compare the efficacy and safety of HLX15-IV in combination with Rd (HLX15-IV-Rd) versus DARZALEX® in combination with Rd (D-Rd) in patients with NDMM who are ineligible for autologous stem cell transplantation (ASCT).
