Belantamab Mafodotin Plus Pomalidomide and Dexamethasone (Pd) Versus Bortezomib Plus Pd in Relapsed/Refractory Multiple Myeloma

Official Title

A Phase III, Multicentre, Open-Label, Randomized Study to Evaluate the Efficacy and Safety of Belantamab Mafodotin in Combination With Pomalidomide and Dexamethasone (B-Pd) Versus Pomalidomide Plus Bortezomib and Dexamethasone (PVd) in Participants With Relapsed/Refractory Multiple Myeloma (DREAMM 8)

Summary:

This study will evaluate the efficacy and safety of belantamab mafodotin in combination with pomalidomide and dexamethasone (Arm A) compared with that of combination of pomalidomide, bortezomib and dexamethasone (Arm B) in participants with relapsed/refractory multiple myeloma (RRMM).
