A Multicenter, Phase 1b, Open-label Study of ABBV-383 Administered Subcutaneously in Subjects With Relapsed or Refractory Multiple Myeloma

Description

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 and pharmacokinetics of ABBV-383 in adult participants with relapsed/refractory (R/R) MM. ABBV-383 is an investigational drug being developed for the treatment of R/R MM. This study is broken into 3 Arms: Arm A with 2 parts and Arm B as an expansion. Participants will receive ABBV-383 as a subcutaneous (SC) injection and intravenous (IV) infusion in Arm A and SC injections of ABBV-383 in Arm B. Around 55 adult participants with relapsed/refractory multiple myeloma will be enrolled at approximately 25 sites across the world In Arm A participants will receive one of two doses of ABBV-383 as an SC inj
