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

Conditions studied: Multiple Myeloma

In brief

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 6 substudies and each substudy consists of a dose escalation phase and dose expansion phase. Participants in substudies 1-4 will receive escalating doses of etentamig alone or with daratumumab and lenalidomide (DR), carfilzomib and dexamethasone (Kd) or lenalidomide (R), followed by etentamig at the dose levels established during the escalation phases alone or with DR, Kd, R. Participants in substudies 1-4 can also receive daratumumab, lenalidomide and dexamethasone (DRd), R, or daratumumab, carfilzomib, and dexamethasone (DKd) as a comparator in the dose expansion phases. Participants in substudies 5-6 will receive escalating doses or at the dose levels established during the escalation phases of ABBV-2001 with iberdomide or mezigdomide. Around 602 adult participants with MM will be enrolled at approximately 75 sites worldwide In substudies 1-3, participants will receive escalating doses of etentamig as Intravenous (IV) infusions, alone or with DR, R or Kd, followed by IV infusions of etentamig at the dose levels established during the escalation phases alone or with IV and DRd, DKd, or R. In substudie 4, participants will receive escalating doses of etentamig as Intravenous (IV) infusions followed by IV infusions of etentamig at the dose levels established during the escalation phase. In substudies 5-6, participants will receive escalating doses of ABBV-2001 as subcutaneous (SC) injections, with oral iberdomide or mezigdomide, followed by SC injections of ABBV-2001 at the dose levels established during the escalation phases with oral iberdomide or mezigdomide. The study duration is approximately 130 months. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and questionnaires.
