Inclusion Criteria

  • RRMM with prior exposure to a proteasome inhibitor, an immunomodulatory drug (IMiD), and an anti-cluster of differentiation (CD38) monoclonal antibody. - Measurable disease defined as at least 1 of the following: - Serum M-protein ≥0.5 grams/deciliter - Urine M-protein ≥200 milligrams (mg)/24-hour - Involved free light chain (FLC) ≥100 mg/liter and an abnormal FLC ratio - Plasmacytoma with a single diameter ≥2 centimeters - Bone marrow plasma cells >30%

Exclusion Criteria

  • Known central nervous system (CNS) myeloma or clinical signs and symptoms of CNS involvement of myeloma. - Active plasma cell leukemia, defined as peripheral blood plasma cells ≥20%. - Radiotherapy or cytotoxic chemotherapy within 2 weeks prior to Day 1 (Baseline), except palliative radiotherapy of limited field is permissible within 2 weeks after discussion with the Sponsor medical monitor. - Antibody-based immunotherapy (monoclonal antibody, bispecific antibody, antibody drug conjugate) within 21 days prior to Day 1 (Baseline). - Proteasome inhibitor therapy or immunomodulatory agent within 14 days prior to Day 1 (Baseline). - Autologous hematopoietic cell transplant within 100 days prior to Day 1 (Baseline). - Allogeneic hematopoietic cell transplant within 180 days prior to Day 1 (Baseline). - Genetically modified adoptive autologous or allogeneic cellular therapy (for example, chimeric antigen receptor T cell, chimeric antigen receptor natural killer) within 12 weeks prior to Day 1 (Baseline). - Corticosteroid therapy ≥140 mg prednisone or equivalent cumulative dose within 14 days prior to Day 1 (Baseline). Note: Other inclusion and exclusion criteria may apply.
