What was measured

TTP was defined as the time from the date of randomization to date of first documented evidence of PD or death due to PD, whichever occurred first. PD per IMWG criteria- Increase of 25 % from lowest response value in one of following: Serum M-component (absolute increase \>=0.5 g/dL); Urine M-component (absolute increase \>=200 mg/24 hours); Only in participants without measurable serum and urine M-protein levels: difference between involved and uninvolved FLC levels (absolute increase \>10 milligram per deciliter \[mg/dL\]); Definite development of new bone lesions/soft tissue plasmacytomas or definite increase in size of existing bone lesions/soft tissue plasmacytomas and Development of hypercalcemia (corrected serum calcium \>11.5 mg/dL) that can be attributed solely to the PC proliferative disorder.

Analysis population: ITT population included all randomized participants.

Groups in this outcome

Lenalidomide + Dexamethasone (Rd)

Participants received Lenalidomide 25 milligrams (mg) capsule orally daily on Day 1 through Day 21 of each 28-day cycle, Dexamethasone 40 mg orally or intravenously (IV) once a week (QW) until disease progression or unacceptable toxicity up to 77.5 months. After completion of treatment, participants entered follow-up phase and were not started on subsequent anti-myeloma therapy without confirmed disease progression (assessed by the International Myeloma Working Group \[IMWG\] criteria).

Daratumumab + Lenalidomide + Dexamethasone (DRd)

Participants received Daratumumab 16 milligrams per kilograms (mg/kg) IV QW for the first 8 weeks (cycles 1-2) and then every 2 weeks (Q2W) for 16 weeks (Cycle 3-6), then every 4 weeks (Q4W) (from Cycle 7 and beyond) (each cycle of 28 days), Lenalidomide 25 mg capsule orally daily on Day 1 through Day 21 of each 28-day cycle, Dexamethasone 40 mg orally or IV QW until disease progression or unacceptable toxicity up to 77.3 months. After implementation of Amendment 8, participants who were ongoing with daratumumab IV treatment were given an option to switch to daratumumab subcutaneous (SC) injection on Day 1 of any cycle, as per investigator's discretion. After completion of treatment, participants entered follow-up phase and were not started on subsequent anti-myeloma therapy without confirmed disease progression (assessed by IMWG criteria).
