This phase I trial is evaluating an intravenous drug (BFCR4350A) in patients with multiple myeloma, who have progressed or not responded to prior treatmentAn Open-Label, Multicenter, Phase I Trial Evaluating the Safety and Pharmacokinetics of Escalating Doses of BFCR4350A in Patients With Relapsed or Refractory Multiple Myeloma

Clinical summary

Summary

Dose escalation: The study drug will be administered intravenously on a 21-day cycle. Initially, cohorts will consist of 1 participant each. Subsequently will consist of at least 3 participants, unless dose-limiting toxicities (DLTs) are observed in the first 2 prior to enrollment of a third participant. For each cohort, treatment with the first dose will be staggered such that the second participant enrolled in the cohort will receive study drug at least 72 hours after the first participant receives it to allow assessment of any severe and unexpected acute or subacute drug or infusion-related toxicities; dosing in subsequent participants in each cohort will be staggered by at least 24 hours. Expansion: Participants exhibiting acceptable safety and evidence of clinical benefit will be administered study drug every 21 days up to a maximum of 17 cycles until objective disease progression is documented or unacceptable toxicity, whichever occurs first.

  • Female participants of childbearing age must agree to remain abstinent or use reliable contraceptive methods during the treatment period, and at least 5 months after last dose of study drug. Women must refrain from breastfeeding during the same period.
  • Male participants must agree to refrain from donating sperm, to abstain or use a condom during the treatment period, and for at least 2 months after the last dose of tocilizumab (if applicable).

Exclusion

  • Inability to comply with protocol-mandated hospitalization and activities restrictions

  • Prior use of any monoclonal antibody, radioimmunoconjugate, or antibody-drug conjugate as anti-cancer therapy within 4 weeks before first infusion
  • Prior treatment with systemic immunotherapeutic agents within 12 weeks or 5 half-lives of the drug, whichever is shorter, before first infusion
  • Prior treatment with chimeric antigen receptor (CAR) T-cell therapy within 12 weeks before first cevostamab infusion
  • Known treatment-related, immune-mediated adverse events associated with prior immunotherapeutic agents
  • Treatment with radiotherapy, any chemotherapeutic agent, or treatment with any other anti-cancer agent (investigational or otherwise) within 4 weeks or 5 half-lives of the drug, whichever is shorter, prior to first cevostamab infusion
  • Autologous stem cell transplantation (SCT) within 100 days prior to first infusion
  • Prior allogeneic SCT or solid organ transplantation
  • Absolute plasma cell count exceeding 500/micro L or 5% of the peripheral blood white cells
  • History of autoimmune disease or of confirmed progressive multifocal leukoencephalopathy
  • Known history of hemophagocytic lymphohistiocytosis (HLH) or macrophage activation syndrome (MAS)

  • Patients with known history of amyloidosis (e.g., positive Congo Red stain or equivalent in tissue biopsy)
  • Patients with lesions in proximity of vital organs that may develop sudden decompensation/deterioration in the setting of a tumor flare
  • History of other malignancy that could affect compliance with the protocol or interpretation of results
  • Current or past history of central nervous system (CNS) disease, or CNS involvement by MM

  • Administration of a live, attenuated vaccine within 4 weeks before first cevostamab infusion or anticipation that such a live attenuated vaccine will be required during the study
  • Received systemic immunosuppressive medications (including, but not limited to, cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-tumor necrosis factor agents), with the exception of corticosteroid treatment <=10 mg/day prednisone or equivalent within 2 weeks prior to first dose of cevostamab and, if applicable, tocilizumab premedication prior to first dose of cevostamab
  • History of illicit drug or alcohol abuse within 12 months prior to screening
  • Any medical condition or laboratory test abnormality that precludes the participant's safe participation in and completion of the study, or which could affect compliance with the protocol or interpretation of results
