Brief Summary:
This research study is being done to learn if the study drug belantamab mafodotin, in combination with other standard medications, can improve multiple myeloma. This study will also help determine what effects, good and/or bad, this combination of study drugs have on subjects and their cancer, and to evaluate the overall response to this study treatment combination.

Condition or disease Intervention/treatment Phase
Multiple Myeloma Drug: Carfilzomib, Lenalidomide, Dexamethasone, Belantamab Mafodotin Phase 1 Phase 2

Detailed Description:
This is a phase I dose escalation and expansion study in RMM and RRMM followed by a single arm phase II expansion in high risk, NDMM. The phase I portion of the protocol will utilize a standard 3+3 dose escalation design to determine the maximum tolerated dose (MTD) and RP2D of the KRd-belantamab mafodotin combination. The phase II portion of the trial is a two-stage design that will assess the efficacy and safety of the combination in newly diagnosed, high-risk MM patients.
