CART-EGFR-IL13Ra2 in Newly Diagnosed GBM Following Initial Radiotherapy
Sponsor: University of Pennsylvania
Summary
This is an open-label phase 1 study to assess the safety, feasibility, pharmacokinetics and preliminary efficacy of autologous T cells co-expressing two CARs targeting the cryptic EGFR epitope 806 and IL3Ra2 (referred to as "CART-EGFR-IL13Ra2 cells"). Patients with newly diagnosed, EGFR-amplified, MGMT-unmethylated glioblastoma who have undergone maximal safe surgical resection will be approached for initial study participation. A two-step screening/eligibility process will be utilized. Following informed consent, subjects who meet Step #1 Eligibility Criteria will remain on study and complete a course of radiotherapy (60 Gy) without temozolomide as per their routine cancer care. If there is no overt evidence of disease recurrence/progression following radiotherapy, additional screening tests/procedures will be performed. Subjects who then meet Step #2 Eligibility Criteria will undergo apheresis collection to initiate cell product manufacturing and surgical placement of a CSF-Ventricular Reservoir to allow for intracerebroventricular injection of the CART-EGFR-IL13Ra2 cells. All subjects will receive a single fixed dose of CART-EGFR-IL13Ra2 cells on Day 0 via intracerebroventricular delivery.

CART-EGFR-IL13Ra2 cells
autologous T cells transduced with a bicistronic lentiviral vector containing a murine scFv targeting EGFR epitope 806 and a humanized scFv targeting IL13Ra2; both scFvs are fused to the 4-1BB and CD3ζ signaling domains.
