A Study to Evaluate the Efficacy and Safety of Belantamab Mafodotin in Combination With Standard of Care in Participants With Relapsed-Refractory Multiple Myeloma (RRMM)

This study is for adults with multiple myeloma (a type of blood cancer) that has come back after being treated earlier or isn't responding to the current treatment. The main goal is to find out if the study drug, belantamab mafodotin, given less often (on an extended schedule) with other cancer medicines, can still treat the cancer effectively while causing fewer side effects, especially those affecting the eyes. The study will also look at how well the treatment works overall and how safe it is when administered to the participants.
