A Study Comparing Daratumumab, VELCADE (Bortezomib), Lenalidomide, and Dexamethasone (D-VRd) With VELCADE, Lenalidomide, and Dexamethasone (VRd) in Participants With Untreated Multiple Myeloma and for Whom Hematopoietic Stem Cell Transplant is Not Planned as Initial Therapy

A Phase 3 Study Comparing Daratumumab, VELCADE (Bortezomib), Lenalidomide, and Dexamethasone (D-VRd) With VELCADE, Lenalidomide, and Dexamethasone (VRd) in Subjects With Untreated Multiple Myeloma and for Whom Hematopoietic Stem Cell Transplant is Not Planned as Initial Therapy

The purpose of this study to determine if the addition of daratumumab to bortezomib + lenalidomide + dexamethasone (VRd) will improve overall minimal residual disease (MRD) negativity rate compared with VRd alone.

This study will evaluate participants with newly diagnosed multiple myeloma (MM) for whom hematopoietic stem cell transplant is not planned as initial therapy. The data available from other available studies suggests that addition of daratumumab with Velcade (bortezomib), lenalidomide, and dexamethasone [VRd] is anticipated to improve the response rates and the depth of response and may lead to improved long-term outcomes in newly diagnosed participants with MM. Daratumumab targets CD38, a protein expressed on the surface of MM cells and other hematopoietic cells. Bortezomib is a proteasome inhibitor, which plays a critical role in the pathogenesis of MM. Lenalidomide has cytotoxic effects on myeloma cells and is capable of inducing apoptosis, or programmed cell death and dexamethasone induces apoptosis in MM cells. The rationale for the study is to utilize the subcutaneous (SC) formulation of daratumumab instead of the intravenous (IV) formulation, which is expected to provide similar exposure and is expected to limit additional toxicity to participants, treated with this quadruplet regimen. The study will consist of 3 phases: Screening (up to 28 days before randomization), Treatment phase (from Cycle 1 [21 days] Day 1 and continues until disease progression) and Follow up (Postintervention). Efficacy evaluations will include measurements of tumor burden/residual disease, myeloma proteins, bone marrow examinations, skeletal surveys, extramedullary plasmacytomas, and serum calcium corrected for albumin. Participants will undergo procedures like electrocardiogram (ECG), chest x-rays or full dose chest CT scans, Pulmonary function test (PFT), spirometry etc. during the course of study. Participants will also be monitored closely for adverse events (AEs), laboratory abnormalities, and clinical response. The duration of the study will be approximately 6.5 years.

Inclusion Criteria:

- Diagnosis of multiple myeloma as documented per International Myeloma Working Group (IMWG) criteria Monoclonal plasma cells in the bone marrow greater than or equal to (>=)10 percentage (%) or presence of a biopsy proven plasmacytoma and documented multiple myeloma satisfying at least one of the calcium, renal, anemia, bone (CRAB) criteria or biomarkers of malignancy criteria. CRAB criteria: Hypercalcemia: serum calcium greater than (>) 0.25 millimoles per liter (mmol/L) (>1 milligram per deciliter [mg/dL]) higher than upper limit of normal (ULN) or >2.75 mmol/L (>11 mg/dL); Renal insufficiency: creatinine clearance less than (<) 40 milliliter per minute (mL/min) or serum creatinine >177 micro millimoles per liter (umol/L) (>2 mg/dL); Anemia: hemoglobin >2 g/dL below the lower limit of normal or hemoglobin <10 g/dL; Bone lesions: one or more osteolytic lesions on skeletal radiography, computed tomography (CT), or positron emission tomography (PET)-CT.

Biomarkers of Malignancy: Clonal bone marrow plasma cell percentage >=60%; Involved: uninvolved serum free light chain (FLC) ratio >=100; >1 focal lesion on magnetic resonance imaging (MRI) studies

• Must have measurable disease, as assessed by central laboratory
• Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1, or 2
• A woman of childbearing potential must have 2 negative serum or urine pregnancy tests at Screening, first within 10 to 14 days prior to dosing and the second within 24 hours prior to dosing
• A woman must agree not to donate eggs (ova, oocytes) for the purposes of assisted reproduction during the study and for a period of 3 months after receiving the last dose of any component of the treatment regimen

Exclusion Criteria:
