This clinical trial is focused on studying a disease called Multiple Myeloma, which is a type of cancer that affects plasma cells in the bone marrow. The trial is testing a treatment known as Belantamab Mafodotin, also referred to by its code name GSK2857916. This treatment is given as a powder that is mixed into a solution and then injected into the bloodstream. The purpose of the study is to explore different ways of giving this treatment to see how safe and effective it is for people whose multiple myeloma has returned or has not responded to previous treatments.
Participants in the study will receive the treatment in one of several different dosing schedules. The study will monitor the effects of the treatment over time, particularly focusing on any changes in the eyes, as these are known to be a possible side effect. The study will also look at how the treatment moves through the body and how the body responds to it. Participants will be observed for any side effects and how well the treatment works in controlling the disease.
The trial will continue for a set period, during which participants will have regular check-ups and tests to track their health and the progress of their multiple myeloma. The study aims to gather information that could help improve treatment options for people with this condition in the future.
