- Brief Summary
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 injection and (IV) infusions, during the 151 week study duration. In Arm B, participants will receive the selected dose from Arm A as SC injections, during the 151 week study duration.
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.

- Primary Outcome Measures
Name Time Method Percentage of Participants Experiencing Cytokine Release Syndrome (CRS) Events Up to 2 cycles (56 days) Cytokine Release Syndrome events will be graded using American Society for Transplantation and Cellular Therapy (ASTCT), with a higher grade indicating higher severity.
Percentage of Participants Experiencing Immune Cell-Associated Neurotoxicity Syndrome (ICANS) Events Up to 2 cycles (56 days) ICANS events will be graded using ASTCT, with a higher grade indicating higher severity.
Maximum Observed Concentration (Cmax) of ABBV-383 Up to 32 weeks Cmax of ABBV-383.
Trough Concentration (Ctrough) of ABBV-383 Up to 32 weeks Ctrough of ABBV-383.
Area Under the Plasma Concentration-time Curve (AUC) of ABBV-383 Up to 24 weeks AUC of ABBV-383.
Time to Cmax (Tmax) of ABBV-383 Up to 32 weeks Tmax of ABBV-383.
- Secondary Outcome Measures
Name Time Method Percentage of Participants Achieving Complete Response (CR) Up to 24 months CR is defined as participants achieving negative immunofixation on the serum and urine, disappearance of any soft tissue plasmacytomas, \< 5% plasma cells in bone marrow, and for participants in whom the only measurable disease is by serum FLC levels, a normal FLC ratio.
Overall Response Rate (ORR) Up to 24 months The ORR is defined as the percentage of participants who achieve a best overall response of confirmed PR or better determined by international myeloma working group (IMWG) criteria, prior to the initiation of subsequent myeloma therapy.
Duration of Response (DoR) Up to 24 months DoR will be defined as the time from the date of first response \[partial response (PR) + VGPR + complete response (CR) + stringent complete response (sCR)\] to the earliest occurrence of progressive disease, or death, whatever occurs first.
Immunogenicity of ABBV-383 as Determined by Neutralizing Anti-Drug Antibodies (NAbs) Up to 27 months Incidence and concentration of NAbs.
Percentage of Participants Achieving Stringent Complete Response (sCR), Up to 24 months sCR is defined as participants achieving negative immunofixation on the serum and urine, disappearance of any soft tissue plasmacytomas, \< 5% plasma cells in bone marrow, normal free light chain (FLC) ratio, and Absence of clonal cells in bone marrow by immunohistochemistry.
Percentage of Participants Achieving Partial Response (PR) Up to 24 months PR is defined as participants achieving \>= 50% reduction of serum M-protein, reduction in 24-hour urinary M-protein by \>= 90% as noted in the protocol, \>= 50% reduction in the size of soft tissue plasmacytomas is also required, if present at baseline.
Progression Free Survival (PFS) Up to 24 months PFS is defined as the duration from the date of randomization to the date of confirmed disease progression (PD) per international myeloma working group (IMWG) criteria, or death, whichever occurs first.
Time to Response (TTR) Up to 24 months TTR is defined as the number of months from the date of first dose to the date of best overall response of CR or PR ('responders') determined by IMWG criteria.
Immunogenicity of ABBV-383 as Determined by Anti-Drug Antibodies (ADAs) Up to 27 months Incidence and concentration of ADAs.
Percentage of Participants Achieving Very Good Partial Response (VGPR) Up to 24 months VGPR is defined as participants achieving serum and urine M-protein detectable by immunofixation but not on electrophoresis, \>= 90% reduction in serum M-protein plus urine, and for participants in whom the only measurable disease is by serum FLC levels, \>= 90% decrease in the difference between involved and uninvolved FLC levels.
