Study Assessing Activity of Intravenous (IV) Etentamig Monotherapy Versus Standard Available Therapies in Adult Participants With Relapsed or Refractory Multiple Myeloma
Recruiting
Multiple myeloma (MM) is a cancer of the blood's plasma cells. The cancer is typically found in the bones and bone marrow (the spongy tissue inside of the bones) and can cause bone pain, fractures, infections, weaker bones, and kidney failure. Treatments are available, but MM can come back (relapsed) or may not get better (refractory) with treatment. This is a study to determine change in disease symptoms of etentamig compared to standard available therapies in adult participants with relapsed/r... Read More
