• Part A: (1) participant has received at least 3 prior lines of therapy for multiple myeloma, or at least 2 prior lines of therapy if at least 1 of those lines consisted of 2 or more multi-agent regimens (eg, multi-agent induction regimen with autologous stem cell transplantation, followed by maintenance regimen). (2) Prior therapy for multiple myeloma has included at least 1 proteasome inhibitor (bortezomib, carfilzomib, ixazomib), at least 1 immunomodulatory agent (lenalidomide, thalidomide, pomalidomide), at least 1 anti-CD38 monoclonal antibody and at least 1 steroid.

(3) Participant had at least a minimal response (MR) to the anti-CD38 antibody containing regimen and had last dose of anti-CD38 monoclonal antibody at least 9 months prior to study entry. Applicable countries in EU and Asia can enroll anti-CD38 naive RRMM patients from DL4 and onwards.
• Part B and the last cohort(s) of Part A: (1) participant has received at least 3 prior lines of therapy for multiple myeloma, or at least 2 prior line of therapy if at least 1 of those lines consisted of 2 or more multi-agent regimens (eg, multi-agent induction regimen with autologous stem cell transplantation, followed by maintenance regimen). (2) Prior therapy for multiple myeloma has included at least 1 proteasome inhibitor (bortezomib, carfilzomib, ixazomib), at least 1 immunomodulatory agent (lenalidomide, thalidomide, pomalidomide) and at least 1 steroid. (3) Prior therapy has not included an anti-CD38 monoclonal antibody.
• Participant has myeloma disease progression on or after last therapy.

• Participant must have measurable disease as defined as at least one of the following:

  • Serum M protein ≥0.5 g/dL (≥5 g/L)
  • Urine M protein ≥200 mg/24 hours
  • Serum FLC assay: Involved FLC assay ≥10 mg/dL (≥100 mg/L) and an abnormal serum
  • FLC ratio (<0.26 or >1.65).
• A male participant must agree to use contraception during the intervention period and for at least 150 days after the last dose of study drug and refrain from donating sperm during this period.

• A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies:

  • Not a woman of childbearing potential (WOCBP)
  • A WOCBP who agrees to follow the contraceptive guidance during the intervention period and for at least 150 days after the last dose of study intervention.

• Participant has congestive heart failure (New York Heart Association) Grade ≥II; cardiac myopathy, active ischemia, or any other uncontrolled cardiac condition such as angina pectoris, clinically significant arrhythmia requiring therapy including anticoagulants, or clinically significant uncontrolled hypertension, QT interval corrected by the Fridericia method >480 msec (Grade ≥2).
• Participant has had acute myocardial infarction within 6 months before first dose of study medication.
• Participant has ongoing sensory or motor neuropathy of National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Grade ≥3.
• Participant has active autoimmune disease including autoimmune hemolytic anemia, idiopathic thrombocytopenic purpura, inflammatory bowel syndrome, pneumonitis or any chronic condition requiring a higher corticosteroid systemic equivalent than prednisone 10 mg daily.
• Known acquired immunodeficiency syndrome (AIDS) or related illnesses or human immunodeficiency virus (HIV) disease requiring antiretroviral treatment, or to have active hepatitis A, B (defined as a known positive hepatitis B surface antigen (HBsAg) result or positive HepB DNA), or C (defined as a known quantitative hepatitis C [HCV] ribonucleic acid RNA results greater than the lower limits of detection of the assay or positive HCV antigen) infection.
• Participant has positive Coombs test at baseline.
