Measure: NUMBER
Unit: Percentage of participants

What was measured

CR or better rate is defined as the percentage of participants who achieve CR or sCR, according to the IMWG criteria. CR is negative immunofixation on the serum and urine, and disappearance of any soft tissue plasmacytomas, and \< 5% PCs in bone marrow. sCR is defined as in addition to CR a normal FLC ratio, and absence of clonal plasma cells (PCs) by immunohistochemistry or immunofluorescence or 2 to 4-color flow cytometry. For 2 participants (1 in each randomized treatment group), data were updated by the study sites which resulted in their inclusion to the response-evaluable analysis set after the primary analysis.

Analysis population: Response-evaluable analysis set included all participants who had a confirmed diagnosis of multiple myeloma and measurable disease at baseline or screening visit, received at least 1 dose of study treatment and had at least 1 post baseline disease assessment. Here, 'N' (number of participants analyzed) signifies number of participants evaluable for this outcome measure and 'n' (number analyzed) signifies number of participants analyzed at each specified timepoints.

Groups in this outcome

Randomized: Lenalidomide+Bortezomib+Dexamethasone (RVd)

Induction and Consolidation Phase (12-week induction phase followed by autologous stem cell mobilization, high-dose chemotherapy \[HDT\] and autologous stem cell transplantation \[ASCT\]; 6-week consolidation phase)- participants received lenalidomide 25 milligrams (mg) orally on Days 1 to 14 of Cycles 1 through 6), bortezomib 1.3 mg per meter square (mg/m\^2) subcutaneously (SC) on Days 1, 4, 8, and 11 and dexamethasone 40 mg orally weekly (20 mg on Days 1, 2, 8, 9, 15 and 16); Maintenance phase (up to 104 week \[until disease progression/up to maximum of 2 years\])- participants received lenalidomide 10 mg orally on Days 1 to 21 throughout each 28-day cycle on Cycles 7 through 9 during maintenance treatment. Beginning at Cycle 10, lenalidomide dose was increased to 15 mg, unless there was tolerability concern. After 2 years of maintenance therapy, participants could continue to lenalidomide monotherapy per standard of care. Long-term follow-up phase- all participants were followed for at least 1 year after last dose of study drug and to continue until death, withdrawal of consent or end of study.

Randomized: Daratumumab+RVd (D-RVd)

Induction and Consolidation Phase (12 week induction phase followed by autologous stem cell mobilization, HDT and ASCT; a 6-week consolidation phase)-participants received RVd with daratumumab 16 milligrams per kilogram (mg/kg) intravenously (IV) weekly on Days 1, 8, and 15 of Cycles 1 to 4 during induction treatment and every 3 weeks on Day 1 of Cycles 5 and 6 during consolidation treatment; Maintenance phase (up to 104-week \[until disease progression/up to maximum of 2 years\])- participants received daratumumab 16 mg/kg every 4 weeks/8 weeks plus lenalidomide 10 mg orally on Days 1 to 21 throughout each 28-day cycle on Cycles 7 through 9 during maintenance treatment. Beginning at Cycle 10, the lenalidomide dose was increased to 15 mg, unless there was a tolerability concern. After 2 years of maintenance therapy, participants could continue to lenalidomide monotherapy per standard of care. Long-term follow-up phase- all participants were followed for at least 1 year after last dose of study drug and to continue until death, withdrawal of consent or end of study. Per protocol amendment 4, to provide flexibility and prioritize safety during the global coronavirus-19 (COVID-19) pandemic, participants were given the option to switch from daratumumab IV to daratumumab SC at the discretion of the investigator.

Safety Run-in: D-RVd

Induction and Consolidation Phase (12 week induction phase followed by autologous stem cell mobilization, HDT and ASCT; a 6-week consolidation phase)-participants received RVd with daratumumab 16 mg/kg IV weekly on Days 1, 8, and 15 of Cycles 1 to 4 during induction treatment and every 3 weeks on Day 1 of Cycles 5 and 6 during consolidation treatment; Maintenance phase (up to 104-week \[until disease progression/up to maximum of 2 years\])- participants received daratumumab 16 mg/kg every 4 weeks/8 weeks plus lenalidomide 10 mg orally on Days 1 to 21 throughout each 28-day cycle on Cycles 7 through 9 during maintenance treatment. Beginning at Cycle 10, the lenalidomide dose was increased to 15 mg, unless there was a tolerability concern. After 2 years of maintenance therapy, participants could continue to lenalidomide monotherapy per standard of care. Long-term follow-up phase- all participants were followed for at least 1 year after last dose of study drug and to continue until death, withdrawal of consent or end of study.
