What was measured

For ALL participants, ORR was defined as percentage of participants who achieved CR or CR with only partial hematological recovery(CRi) as per NCCN criteria. CR for ALL: less than 5% blasts in 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. CRi for ALL: less than 5% blasts in bone marrow; no evidence of circulating blasts or extramedullary disease; partial recovery of peripheral blood counts not meeting criteria for CR. For LL participants, ORR was defined as percentage of participants who had CR or PR during or after treatment administration but prior to start of subsequent anti-cancer therapy or allogeneic hematopoietic stem cell transplant(HSCT). CR for LL: disappearance of all evidence of disease from all sites. PR for LL: decrease of \>=50% in sum of products of diameter of lesions of up to 6 of largest dominant nodes or nodal masses with no new lesions.

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