AI-Summary

What this Trial Is About

This is a phase I dose-escalation study to evaluate the safety of partially human leukocyte antigen (HLA)-matched multi tumor-associated antigen-specific T cell (TAA-T) therapy for patients with high-risk solid tumors due to the presence of refractory, relapsed and/or minimal residual detectable disease following conventional therapy. Conventional therapy may include chemotherapy, surgery, radiation, autologous stem cell transplant, or targeted therapy.

  • Age 6 to under 18 years for Arm B
  • Patient or parent/guardian able to provide informed consent
  • No systemic steroid use within 1 week before TAA-T infusion
  • Karnofsky/Lansky score of 50% or higher
  • Left ventricular ejection fraction greater than 50% or LV systolic dysfunction over 27% if history of total body irradiation
  • Hemoglobin greater than 7.0 g/dL (transfusion allowed)
  • Bilirubin 2.5 mg/dL or less
  • AST/ALT up to 5 times the upper limit of normal for age
  • Serum creatinine less than 1.0 mg/dL or up to 2 times upper limit of normal for age
  • Pulse oximetry over 90% on room air
  • Negative pregnancy test for females of childbearing age
  • Use of contraceptive measures during study if age appropriate
  • For patients receiving lymphodepleting chemotherapy: ANC over 1000 /ul and platelet count over 75,000 /ul
Not Eligible
