Eligible participants with newly diagnosed myeloma who are not considered eligible or refuse bone marrow transplant will be enrolled. Participants will be randomized to either belantamab mafodotin or daratumumab given in combination with bortezomib, lenalidomide and dexamethasone. Treatment will continue until disease progression, unacceptable side effects or withdrawal of consent.
Belantamab mafodotin is a targeted cancer treatment that works against multiple myeloma cells. It combines a homing device (an antibody) with a powerful cell-killing drug (a toxin), delivering the toxin directly to cancer cells while largely sparing healthy cells.
Minimal residual disease (MRD) testing will be done on bone marrow samples obtained standardly during your treatment. MRD shows whether a very small number of cancer cells can still be detected after treatment, even if standard lab tests shows no signs of cancer.
The purpose of this study is to evaluate if belantamab mafodotin, bortezomib, lenalidomide and dexamethasone (BVRd) improves minimal residual disease (MRD) negative status and/or prolongs progression-free survival (PFS) compared with daratumumab, bortezomib, lenalidomide and dexamethasone (DVRd) in participants with newly diagnosed multiple myeloma.
Patient must have suspected or confirmed newly diagnosed multiple myeloma (MM) by International Myeloma Working Group (IMWG) criteria and must not have received more than one cycle of any myeloma treatment.
Patient must be considered ineligible for autologous stem cell transplantation by the treating physician because of their age (≥ 70 years) or aged 18 - 70 years with the presence of underlying medical conditions likely to have a negative impact on tolerability of high-dose chemotherapy with stem-cell transplantation, making them transplant ineligible, OR transplant-eligible and refusing stem-cell transplantation until first relapse or later.
Patient must have measurable or evaluable disease as defined by having one or more of the following, obtained within 28 days prior to randomization.
