  • Expected survival ≥ 3 months.
  • ECOG performance status 0 or 1.
  • Diagnosed with active multiple myeloma per IMWG criteria.
  • Relapsed or refractory multiple myeloma and refractory to the most recent line of therapy.
  • Disease progression or non-response to the most recent therapy.
  • Measurable disease as defined by serum/urine M-protein or serum free light chain.
  • Adequate bone marrow, hepatic, renal, and coagulation function.
  • Female participants of childbearing potential and male participants with partners of childbearing potential must agree to use effective contraception.
  • Willing and able to provide written informed consent and comply with study procedures.

You may not qualify if:

  • Diagnosis of amyloidosis, plasma cell leukemia, Waldenström's macroglobulinemia, or POEMS syndrome.
  • Central nervous system involvement by tumor.
  • History of ≥ Grade 3 CRS with prior T-cell redirecting therapy.
  • Requirement for dialysis or plasmapheresis within 14 days prior to study drug.
  • Prior treatment-related AEs not recovered to ≤ Grade 1 (except alopecia, peripheral neuropathy, or controlled endocrinopathies).
  • Concurrent participation in another clinical study.
  • Prior anti-tumor therapy within specified washout periods.
  • Major surgery within 28 days prior to informed consent or planned during the study.
  • Live attenuated vaccine within 4 weeks prior to first dose or planned during the study.
  • Significant comorbidity that in the investigator's judgment would interfere with study participation or safety.
