DREAMM-9: Phase III study of belantamab mafodotin plus VRd versus VRd alone in transplant-ineligible newly diagnosed multiple myeloma (TI NDMM).

TPS8556 Background: Bortezomib, lenalidomide, and dexamethasone (VRd) is the standard of care for transplant-eligible and TI NDMM, but relapse is usually inevitable. The median progression-free survival (PFS) is ~3 years for patients with TI NDMM, and with each relapse, the duration of response (DoR) diminishes, highlighting the need for novel, effective, targeted agents. Single-agent belantamab mafodotin is a first-in-class B-cell maturation...
