Detailed eligibility will be discussed when reaching out to the study team.
The goal of this clinical trial is to compare the safety and efficacy of belantamab mafodotin combinated with lenalidomide and dexamethasone to the combination of daratumumab, lenalidomide and dexamethasone in participants who have newly diagnosed multiple myeloma and are not eligible for autologous stem cell transplantation. The study also wants to determihne if the study drug is safer and works better than the current standard of care treatment.
Belantamab mafodotin is considered investigational, which means it has not been approved by the U.S. Food and Drug Administration (FDA).
Belantamab mafodotin will be combined with 2 drugs already approved by the FDA to treat multiple myeloma: lenalidomide and dexamethasone. Everyone in the study will take these 2 standard drugs, but some will also take, daratumumab, instead of belantamab mafodotin. Daratumumab is also FDA-approved for multiple myeloma.
Participants will be randomized to one of two treatment groups. Randomization is like flipping a coin and there is a 50/50 chance of being assigned to either group.
Depending on the treatment group, participants will either get intravenous (IV through a vein in the arm) treatment or subcutaneous injection (needle beneath the skin). Both groups will also take capsules and tablets by mouth.
There is no defined length of time for this study, and the duration of the study will be different for every participant depending on their health.
