A Study to Assess Change in Disease Activity and Adverse Events (AE)s in Adult Participants With Multiple Myeloma Receiving T Cell Engaging Bi/Tri-specific Antibodies Intravenously (IV)/Subcutaneously (SC) Alone or in Combinations
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 the safety, efficacy, and pharmacokinetics of Etentamig and ABBV-2001 in adult participants with MM.
Etentamig and ABBV-2001 are investigational drugs being developed for the treatment of MM. This study is broken into
