Eligibility Criteria

Inclusion

  • RECIPIENT PROCUREMENT (BLOOD COLLECTION FOR TSA-T MANUFACTURING) INCLUSION CRITERIA
  • New diagnosis of CNS embryonal tumors: medulloblastoma, embryonal tumor with multilayered rosettes (ETMR), pineoblastoma, atypical teratoid/rhabdoid tumor, and embryonal tumor, not otherwise specified (NOS).
  • \<5 years of age at enrollment.
  • Lansky score of ≥60% (see appendix B).
  • Organ function:
  • ANC ≥750/µL. Absolute lymphocyte count (ALC) \>500/μL. Platelets ≥75K. Bilirubin ≤3xULN. Aspartate aminotransferase (AST)/ Alanine aminotransferase (ALT) \<5x upper limit of normal (ULN). Serum creatinine ≤1.0mg/dL or 1.5x ULN for age (whichever is higher). Pulse oximetry \>90% on room air.
  • Parent(s)/guardian(s) capable of providing informed consent.
  • Availability of sufficient pre-trial fresh frozen tumor tissue (approximately 50 mg).
  • Patient deemed to be of sufficient size to undergo PBMC pheresis for TSA-T generation and PBSC rescue.
  • Patient is a surgical candidate for placement of Rickham reservoir in the opinion of a physician.
  • RECIPIENT INCLUSION CRITERIA FOR INITIAL TSA-T ADMINISTRATION AND FOR ADDITIONAL INFUSIONS
  • Lansky score of ≥60%.
  • Organ function:
  • Bilirubin ≤3x ULN. AST/ALT ≤5x ULN. Serum creatinine ≤1.0mg/dL or 1.5x ULN for age (whichever is higher). Pulse oximetry \>90% on room air.
  • \- Neurologic status: Patient must have a stable neurologic exam for 2 weeks, on a stable or decreasing dose of steroids, prior to administration of the first dose of TSA-T cells, and stability for 1 week prior to all subsequent infusions. The exams demonstrating stability must be performed by the study team, although these may occur via telemedicine if necessary. Patient must agree to a brief (\<72 hours) course of steroids

Exclusion

  • PROCUREMENT EXCLUSION CRITERIA
  • Patients with uncontrolled infections.
  • Patients with known HIV infection.

  • Patients with medulloblastoma of the SHH subtype.
  • Patients who have overly bulky tumors on imaging are ineligible. These include the following:
  • Tumor with any evidence of herniation or significant midline shift. Tumor with a significant brainstem component. Patients who are deemed to have overly bulky tumor by the principal investigator (PI) of the study.
  • RECIPIENT EXCLUSION CRITERIA FOR INITIAL AND SUBSEQUENT TSA-T INFUSIONS
  • Patients with uncontrolled infections.
  • Patients who have overly bulky tumors on imaging are ineligible. These include the following:
  • Tumor with any evidence of herniation or significant midline shift. Tumor with a significant brainstem component. Patients who are deemed to have overly bulky tumor by the PI of the study.
  • Patients who received ATG, Campath or other immunosuppressive T cell monoclonal antibodies within 28 days of TSA-T infusion.
  • Patients receiving dexamethasone at a dose of \>0.05mg/kg. All patients who qualify based on the above inclusion and exclusion criteria will be eligible for participation in this study.
