Multi-antigen T Cell Infusion Against Neuro-oncologic Disease

This Phase I dose-escalation trial is designed to determine the safety and feasibility of rapidly generated tumor multi-antigen associated specific cytotoxic T lymphocytes (TAA-T) in patients with newly diagnosed diffuse intrinsic pontine gliomas DIPGs (Group A) or recurrent, progressive, or refractory non-brainstem CNS malignancies (Group B). Pediatric and adult patients who have high-risk CNS tumors known to typically have positivity for one or more Tumor Antigen Associated (TAA) (WT1, PRAME and/or Survivin) will be eligible. TAA-T will all be generated from patient peripheral blood mononuclear cells (PBMC). Group A patients (DIPG): The first TAA-T dose will be infused any time 14 days or more after completion of radiotherapy. Group B patients (other recurrent/progressive/refractory CNS tumors): The first TAA-T dose will be infused any time 14 days or more after completing most recent course of conventional (non-investigational) therapy for their disease AND after appropriate washout periods as detailed in eligibility criteria.
