简要总结
The purpose of this study is to compare the efficacy of daratumumab in combination with lenalidomide and dexamethasone to that of lenalidomide and dexamethasone in terms of progression-free survival (PFS) in participants with newly diagnosed multiple myeloma (a blood cancer of plasma cells) who are not candidates for high dose chemotherapy (treatment of disease, usually cancer, by chemical agents) and autologous stem cell transplant (ASCT).
详细描述
This is a Phase 3, randomized (study drug assigned by chance), open-label (participants and researchers are aware about the treatment, participants are receiving), active-controlled (study in which the experimental treatment or procedure is compared to a standard treatment or procedure), parallel-group (each group of participants will be treated at the same time), and multicenter (when more than one hospital or medical school team work on a medical research study) study in participants with newly diagnosed multiple myeloma and who are not candidates for high dose chemotherapy and ASCT. All the eligible participants will be randomly assigned to receive either lenalidomide and dexamethasone (Rd) (Arm A) or daratumumab in combination with lenalidomide and dexamethasone (DRd) (Arm B). Daratumumab (16 milligram per kilogram [mg/kg]) will be administered weekly for first 8 weeks (Cycles 1 to 2) of treatment and then every other week for 16 weeks (Cycles 3 to 6), then every 4 weeks (from Cycle 7 and beyond) until progression of disease or unacceptable toxicity. Lenalidomide will be administered at a dose of 25 mg orally on Days 1 through 21 of each 28-day cycle, and dexamethasone will be administered at a dose of 40 mg once a week for both treatment arms. Participants in both treatment arms will continue lenalidomide and dexamethasone until disease progression or unacceptable toxicity. All participants randomized to Treatment Arm B (DRd) in this study initially received daratumumab IV formulation; however, following implementation of protocol amendment 8, participants still receiving treatment with daratumumab IV will have the option to switch to daratumumab SC on Day 1 of any cycle, at the discretion of the investigator. Daratumumab subcutaneous (SC) will be administered by SC injection at a fixed dose of 1800 mg once every 4 weeks until documented progression, unacceptable toxicity, or study completion. Participants in Arm A who have sponsor-confirmed disease progression may have the option to receive daratumumab provided by the sponsor (in any subsequent line of therapy) in the Follow-up phase. The study consists of 3 phases: Screening Phase (within 21 days prior to the first dose administration on Day 1), Treatment Phase (Day 1 up to discontinuation of all study treatment), and Follow-up Phase (from discontinuation of all study treatment up to death, lost to follow up, consent withdrawal, or study end, whichever occurs first). The maximum duration of study will be 7 years after last participant is randomized. Efficacy will primarily be evaluated by PFS. Participants' safety will be monitored throughout the study.

结局指标
主要结局
Progression-free Survival (PFS)
时间窗: From randomization (Day -3) to disease progression, death, subsequent anti-myeloma therapy, withdrawal of consent to study participation or clinical cut-off (CCO) whichever occurs first (up to 3.5 years)
PFS was defined as time from date of randomization to either progressive disease (PD) or death, whichever occurred first based on computerized algorithm as per IMWG criteria. PD was defined as an increase of 25 percent (%) from the lowest response value in one of the following: serum and urine M-component (absolute increase must be greater than or equal to \[\>=\] 0.5 gram per deciliter \[g/dL\] and \>=200 milligram \[mg\]/24 hours respectively); Only in participants without measurable serum and urine M-protein levels the difference between involved and uninvolved free light chain (FLC) levels (absolute increase must be greater than \[\>\]10 mg/dL); Definite development of new bone lesions or soft tissue plasmacytomas or definite increase in the size of existing bone lesions or soft tissue plasmacytomas; Development of hypercalcemia (corrected serum calcium \>11.5 mg/dL) that could be attributed solely to Plasma cell (PC) proliferative disorder.
