What was measured

Time from first evidence of confirmed assessment of sCR, CR, VGPR, PR, or MR to first confirmed disease progression, or to death due to any cause. DOCB is defined only for patients with a confirmed MR or better.

Analysis population: Analysis was performed using the Full Analysis Set (FAS).

Groups in this outcome

Arm A (Melflufen+Dexamethasone+Daratumumab)

Treatment was given in 28-day cycles in an outpatient treatment setting. * Melflufen 30 mg intravenous (i.v.) infusion on Day 1 of each cycle * Dexamethasone 40 mg per oral (p.o.) weekly (20 mg p.o. weekly if ≥75 years) * Daratumumab 1800 mg subcutaneously (s.c.) on Days 1, 8, 15, and 22 in Cycles 1 and 2, on Days 1 and 15 in Cycles 3 to 6, and on Day 1 from Cycle 7

Arm B (Daratumumab)

Treatment was given in 28-day cycles in an outpatient treatment setting. • Daratumumab 1800 mg s.c. on Days 1, 8, 15, and 22 in Cycles 1 and 2, on Days 1 and 15 in Cycles 3 to 6, and on Day 1 from Cycle 7
