Phase 2 Study of Extended Dosing of Belantamab Mafodotin with Standard Treatments for Adults with Relapsed or Resistant Multiple Myeloma

What this Trial Is About

This research aims to evaluate the efficacy and safety of belantamab mafodotin given with standard cancer treatments in adults with relapsed or refractory multiple myeloma, a type of blood cancer that has returned or is not responding to prior treatments. The study focuses on whether giving belantamab mafodotin less frequently can still control the cancer while reducing side effects, especially those affecting the eyes. It is a phase 2, open-label study sponsored by GlaxoSmithKline. Participants will receive belantamab mafodotin combined with one of three standard treatment regimens pomalidomide and dexamethasone bortezomib and dexamethasone or carfilzomib and dexamethasone. The study uses an extended dosing schedule to assess if less frequent dosing maintains effectiveness. The treatment continues as per the assigned combination, with no randomization, in multiple centers. During the study, participants will be regularly assessed for response to treatment, including overall response rate and complete response rate, up to about 52 months. Safety will be monitored by recording side effects and eye health through ophthalmic exams. Participants will undergo laboratory tests and clinical evaluations throughout the study. The research will also track how well patient-reported eye symptoms match clinical findings, with the total study duration extending up to approximately four years.
