  • Failure to achieve at least a PR to most recent therapy with daratumumab or other anti-CD38 therapy.
  • Daratumumab or other anti-CD38 antibody therapy was discontinued due to toxicity.
  • Relapse within 60 days of intensive treatment (at least every other week) of daratumumab or other anti-CD38 antibody therapy.
  • Prior treatment with daratumumab or other anti-CD38 antibody within 6 months prior to first dose of study drug.
• For participants in Part 2 and 3:
  • Participant is refractory to any proteasome inhibitor, defined as progression on or within 60 days of the last dose of a proteasome inhibitor-containing regimen.
  • Participant has had prior treatment with proteasome inhibitor within 60 days prior to first dose of study drug.
• Treatment with anti-myeloma chemotherapy, radiotherapy, biological, immunotherapy or an investigational therapy, including targeted small molecule agents within 2 weeks or 5 half-lives (whichever is longer and/or applicable) before first dose.
• Treatment with anti-myeloma monoclonal antibodies within 6 weeks prior to first dose.
• Recent corticosteroid therapy at a cumulative dose equivalent to \>= 140 mg of prednisone, cumulative dose equivalent to \>= 40 mg of dexamethasone, or a single dose equivalent to \>= 40 mg of dexamethasone within 2 weeks prior the first dose of study drug.

Más betegség

• History of other active malignancies including myelodysplatic syndromes (MDS) within the past 3 years with the exceptions of:
  • Basal cell carcinoma of the skin or localized squamous cell carcinoma of the skin.
  • Prostate cancer Gleason grade 6 or lower AND with stable Prostate Specific Antigen (PSA) levels off treatment
  • Previous malignancy with no evidence of disease confirmed and surgically resected (or treated with other modalities) with curative intent and unlikely to impact survival during the duration of the study.
• Known active severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.
• Has a hypersensitivity or allergy to any of the components of study therapy, excipient or boron.
• Known allergies, hypersensitivities, or intolerance to monoclonal antibodies or human proteins, or their excipients, or known sensitivity to mammalian-derived products (see daratumumab prescribing information).

Egyéb

• Participant has received previous multiple myeloma treatment as defined in the protocol.
• Bone marrow aspirate samples have been collected.
• To qualify for Part 1 and 3, the participant must be t(11;14) positive as determined by an analytically validated Fluorescent In Situ Hybridization (FISH) assay per central laboratory testing.
• Participants must have adequate hematologic, renal and hepatic function.
