* Confirmed diagnosis of multiple myeloma as defined by the International Myeloma Working Group (IMWG) criteria. * Previously treated with at least 1 prior line of multiple myeloma (MM) therapy, and must have documented disease progression during or after their most recent therapy. * Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2. * Must have at least 1 aspect of measurable disease, defined as one of the following; 1. Urine M-protein excretion \>=200 mg per 24-hour, or 2. Serum M-protein concentration \>=0.5 grams per deciliter (g/dL), or 3. Serum free light chain (FLC) assay: involved FLC level \>=10 mg per dL (\>=100 mg per liter) and an abnormal serum free light chain ratio (\<0.26 or \>1.65). * All prior treatment-related toxicities (defined by National Cancer Institute Common Toxicity Criteria for Adverse Events \[NCI-CTCAE\] version 5.0) must be \<=Grade 1 at the time of enrollment, except for alopecia. * Adequate organ function
