What this Trial Is About

This phase II trial tests alternate doses and dosing schedules of belantamab mafodotin in treating patients with triple-class multiple myeloma that has come back (after a period of improvement) (recurrent) and/or does not respond to treatment (or that has not responded to previous treatment) (refractory). Belantamab mafodotin is a monoclonal antibody, belantamab, linked to a chemotherapy drug, mafodotin. Belantamab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as BCMA receptors, and delivers mafodotin to kill them. This trial may help researchers determine if alternate doses and dosing schedules work better in preventing certain side effects, such as eye toxicity, and treating patients with recurrent or refractory multiple myeloma.
