What was measured

Time to first response, time to VGPR or better, time to CR or better and time to best response was reported for this endpoint. Time to response: time from date of randomization to first efficacy evaluation that met criteria for PR/better as their best response (PR, CR, or better) based on IMWG criteria. PR: \>=50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by \>=90% or to \<200 mg/24 hours. If serum and urine M-protein were not measurable, a decrease of \>=50% in difference between involved and uninvolved FLC levels was required in place of M-protein criteria. Based on computerized algorithm, according to IMWG response criteria, VGPR or better: proportion of participants with a response of VGPR or better (i.e., VGPR, CR or sCR), CR or better: proportion of participants with a response of CR or better (i.e., CR or sCR).

Analysis population: Response evaluable population included all participants with confirmed diagnosis of multiple myeloma and measurable disease at baseline or screening visit and received at least one administration of study treatment and had adequate postbaseline disease assessments. Here, 'N' (number of participants analyzed) signifies number of participants evaluable for this outcome measure. Here 'n' signifies number of participants analyzed at specified timepoints.

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).
