Multiple myeloma (MM) is an incurable disease characterized by the growth of monoclonal plasma cells in the bone marrow. The purpose of this study is to assess the adverse events and change in disease state of ABBV-383 in adult participants with relapsed/refractory (R/R) multiple myeloma (MM). Adverse events and change in disease state will be assessed.

ABBV-383 is an investigational drug being developed for the treatment of R/R MM. Study doctors put the participants in groups called treatment arms. Two doses of ABBV-383 will be explored. Each treatment arm receives a different dose of ABBV-383 to determine a tolerable dose. Approximately 12 adult participants with R/R MM will be enrolled in the study in approximately 6 sites in Japan.

Participants will receive intravenous (IV) ABBV-383 at two increasing doses in 21-day cycles.

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 an approved institution (hospital or clinic). The effect of the treatment will be frequently checked by medical assessments, blood tests, and and monitoring of side effects.

Inclusion Criteria

Eastern Cooperative Oncology Group (ECOG) performance of <= 2
Must have adequate bone marrow function as defined in the protocol
Must meet laboratory parameters as outlined in the protocol
Must have a confirmed diagnosis of relapsed/refractory (R/R) multiple myeloma (MM) with documented evidence of progression during or after the participant's last treatment regimen based on the investigator's determination of the International Myeloma Working group (IMWG) criteria
Relapsed defined as previously treated myeloma that progresses and requires initiation of salvage therapy, but does not meet criteria for refractory myeloma
Refractory defined as disease that is nonresponsive (failure to achieve minimal response or development of progressive disease) while on primary or salvage therapy, or progresses within 60 days of last therapy
Must have received at least 3 prior lines of therapy (including exposure to a
proteasome inhibitor (PI), an immunomodulatory imide (IMiD), and an anti-CD38
Must have measurable disease within 28 days of enrollment, defined as at least 1 of the following
Serum M-protein >= 0.5 g/dL (>= 5 g/L)
Urine M-protein >= 200 mg/24 hours
Serum free light chain (FLC) >= 100 mg/L (involved light chain) and an abnormal serum kappa lambda ratio only for participants without measurable serum or urine M-protein
Consents to a fresh pretreatment bone marrow tumor biopsy or has adequate archival
bone marrow tumor tissue that was collected within 12 weeks prior to screening
and without intervening treatment

Exclusion Criteria
