What was measured

Complete response based on the modified NCCN criteria was defined as: less than 5% blasts in the bone marrow; no evidence of circulating blasts or extramedullary disease; full recovery of peripheral blood counts: platelets \>100\*10\^9 cells/L and ANC \>1.0\*10\^9 cells/L. This outcome measure was planned to be analyzed for specified arms only.

Analysis population: The all treated analysis set included all enrolled participants who received at least 1 dose of daratumumab.
