Overview

Multiple myeloma (MM) is a plasma cell disease characterized by the growth of clonal plasma cells in the bone marrow. The purpose of this study is to assess the safety, tolerability, and how ABBV-438 moves through the body, in adult participants with relapsed/refractory (R/R) MM. Adverse events, tolerability, how ABBV-438 moves through the body will be assessed. ABBV-438 is an investigational drug being developed for the treatment of R/R MM. Study doctors put the participants in groups called treatment arms broken into 2 parts. ABBV-438 will be given alone and multiple doses will be explored. This study will include a dose escalation phase (Part 1) to determine the best dose of ABBV-438, followed by a dose expansion phase (Part 2) to confirm the dose. Approximately 127 adult participants with R/R MM will be enrolled in the study in approximately 24 sites worldwide. Participants will receive intravenous (IV) ABBV-438 alone first in multiple doses in the dose escalation phase (Part 1); then in 1 of 2 doses from Part 1 in the dose expansion phase (Part 2). The overall study duration will be approximately 69.5 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 an approved institution (hospital or clinic). The effect of the treatment will be frequently checked by medical assessments, blood tests, questionnaires and side effects.

Inclusion Criteria: * Has relapsed or refractory 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 standard International Myeloma Working Group (IMWG) (2016) response criteria: * Relapsed defined as previously treated myeloma that progresses and requires initiation of salvage therapy; * Refractory defined as disease that is nonresponsive (failure to achieve minimal response) while on last therapy, or progresses within 60 days of last therapy. * Has measurable disease at screening, defined by at least 1 of the following within 28 days prior to enrollment: * Serum M-protein \>= 0.5 g/dL (\>=5 g/L); OR; * Urine M-protein \>= 200 mg/24 hours; OR; * Involved serum free light chain (sFLC) \>= 10 mg/dL (100mg/L), provided serum FLC ratio is abnormal; * Must have had 3 or more prior lines of therapy with exposure to a proteasome inhibitor (PI), an immunomodulatory imide drugs (IMiD), and an anti-CD38 therapy and are intolerant to, or unable to access, available therapies that are known to confer clinical benefit to participants with relapsed or refractory (R/R) MM. Note: A line of therapy consists of relapsed or refractory 1 complete cycle of a single agent, a regimen consisting of a combination of several drugs, or a planned sequential therapy of various regimens. Exclusion Criteria: * Known history of Central Nervous System involvement by MM. * History of idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis obliterans), drug-induced pneumonitis, or idiopathic pneumonitis.

Number of Participants With Adverse Events (AE)

An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. A serious adverse event (SAE) is defined as any untoward medical occurrence, whether associated with study drug or not, that results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is an important medical event requiring medical or surgical intervention to prevent serious outcome.
