Am I Eligible?

The following criteria is a partial list of reasons why patients may or may not be eligible to participate in this clinical trial. Further evaluation with a medical professional will be required to determine full eligibility.

The following criteria is provided for health care professionals.

Inclusion Criteria:

  • Must have relapsed or refractory multiple myeloma (RRMM) after having received prior lines of anti-myeloma treatments.
  • Measurable disease as defined by one of the following: abnormal serum or M-protein levels; abnormal serum free light chain (FLC) assay; ≥ 30% clonal plasma cells in the bone marrow aspirate or biopsy sample
  • Evidence of cell membrane CD38 expression as determined by immunohistochemistry (IHC) analysis ofbone marrow biopsy or extramedullary plasmacytoma
  • Pulse oximetry ≥ 92% on room air
  • Have a life expectancy ≥ 12 weeks
  • Be willing and able to comply with the study schedule and all study requirements
  • Willing to follow contraception guidelines

Exclusion Criteria:

  • Previous treatment with any systemic therapy for multiple myeloma within 14 days prior to start of study dose
  • Treatment with any cellular therapy within 8 weeks prior to start of study dose
  • Have any unresolved toxicity ≥ Grade 2 from previous anticancer therapies
  • A history of brain metastasis or spinal cord compression
  • Has an ECOG performance status (PS) ≥ 3
  • Has received allogeneic hematopoietic stem cell transplantation (HSCT) within 6 months, has active graft-versus-host disease (GvHD) following transplant, or is currently receiving immunosuppressive therapy following transplant
  • Has any clinically significant low baseline lab results for hemoglobin, platelet counts, and neutrophil counts at screening unless resulting from underlying RRMM
  • Has any clinically significant elevated baseline lab results for serum creatinine, AST or β2 microglobulin
  • Abnormal INR or aPTT, unless on a stable dose of an anticoagulant
  • Has known HIV or acquired immunodeficiency syndrome-related illness, acute or history of chronic hepatitis B or C
  • Is currently pregnant or breast feeding or planning on either during the study.
  • Has an active bacterial, viral, or fungal infection
  • Has active plasma cell leukemia
  • Has extramedullary plasmacytoma(s)
  • Has any significant medical condition, abnormality, or psychiatric illness that would prevent study participation
  • Has left ventricular ejection fraction (LVEF) < 40%
  • Has second primary malignancies (SPMs) in addition to multiple myeloma if the SPM has required therapy within the last 3 years or is not in complete remission
  • Has any additional clinical history of the CNS or cardiovascular disease that would place the patient at an unacceptable risk if the patient participates in the study
