Clinical Trial Summary

A pilot study to determine the safety and efficacy of chimeric antigen receptor T cell (autologous T cells transduced with a lentiviral vector expressing chimeric antigen receptor with or without anti-PDL1 antibody) personalized immunotherapy for patients with recurrent malignant gliomas based on the expression of tumor specific/associated antigens (EGFRVIII, IL13Rα2, Her-2, EphA2, CD133, GD2).

3. Serum creatinine less than or equal to 1.5 x upper limit of normal

4. Coagulation tests prothrombin time (PT) and partial thromboplastin time (PTT) have to be within normal limits, unless the patient has been therapeutically anti-coagulated for previous venous thrombosis.
