Brief Summary

B-cell maturation antigen (BCMA) is a target present on tumor cells in participants with multiple myeloma. Belantamab mafodotin (GSK2857916); is an antibody-drug conjugate (ADC) containing humanized anti-BCMA monoclonal antibody (mAb). This is a phase I/II, randomized, open-label, platform study designed to evaluate the effects of belantamab mafodotin in combination with other anti-cancer drugs in participants with relapsed/refractory multiple myeloma. The Platform design incorporates a single master protocol, where multiple treatment combinations, as sub-studies, will be evaluated simultaneously.

  • Participants who have received transfusion of blood products within 2 weeks before the first dose of study drug.
  • Participants must not receive live attenuated vaccines within 30 days prior to first dose of study treatment or whilst receiving belantamab mafodotin +- partner agent in any sub-study arm of the platform trial and for at least 70 days following last study treatment.
  • Participants with presence of active renal condition (infection, requirement for dialysis or any other condition that could affect participant's safety). Participants with isolated proteinuria resulting from MM.
  • Participants with Known HIV infection, unless the participant can meet all criteria: a) established anti-retroviral therapy for at least 4 weeks and HIV viral load\<400 copies/mL b) CD4+ T-cell (CD4+) counts \>= 350 cells/microliter (µL) c) No history of AIDS-defining opportunistic infections within the last 12 months in which case the participant would be eligible for CE Phase only.

Model Details: There will be a dose exploration (DE) phase which will evaluate the safety and tolerability profile of belantamab mafodotin when administered in combination with other anti-cancer treatments. A recommended Phase 2 dose (RP2D) for each combination treatment will be identified based on the safety and preliminary efficacy in DE. This will be followed by a cohort expansion (CE) phase which will evaluate the clinical activity of the combination treatment in comparison to belantamab mafodotin monotherapy in additional participants.
