CTIM-33. PHASE II TRIAL OF VACCINE IMMUNOTHERAPY IN PRIMARY GLIOBLASTOMA: ADJUNCTIVE AUTOLOGOUS DENDRITIC CELLS PULSED WITH LYSATE FROM IRRADIATED SELF-RENEWING AUTOLOGOUS TUMOR CELLS (AV-GBM-1)

ABSTRACT: Abstract In primary glioblastoma (GBM), overall survival (OS) is poor despite standard aggressive therapy. Adjunctive AV-GBM-1 vaccine immunotherapy may improve OS. In this multi-institutional phase II trial, key eligibility criteria for intent-to-treat (ITT) enrollment were: (1) primary GBM, (2) age < 70 years when GBM was resected, (3) successful GBM cell culture, (4) successful monocyte collection by leukapheresis, (5) KPS > 70 post-surgery, and (6) plan to treat with concurrent RT/TMZ. Dendritic cells (DC) were differentiated from monocytes by culturing in IL-4 and granulocyte-macrophage colony stimulating factor (GM-CSF). AV-GBM-1 consisted of autologous DC incubated with autologous tumor antigens contained in the lysate of irradiated cultured GBM cells. After recovery from RT/TMZ, do
