This clinical trial focuses on patients with newly diagnosed multiple myeloma who cannot receive a transplant. The study tests a combination of several medications: belantamab mafodotin, lenalidomide, dexamethasone, and nirogacestat. Multiple myeloma is a type of blood cancer that affects plasma cells, which are cells in the bone marrow that help fight infections.
The purpose of this study is to determine if this combination of medications is safe and effective for treating patients with newly diagnosed multiple myeloma. The study will evaluate how well patients tolerate the treatment and measure how well the cancer responds to these medications when used together.
The treatment involves taking some medications by mouth (lenalidomide, dexamethasone, and nirogacestat) and receiving belantamab mafodotin through an intravenous infusion (through a vein). During the study, participants will receive regular medical check-ups and tests to monitor their health and evaluate how well the treatment is working. The study will last approximately four years.
