Chemotherapy, Radiation Therapy, and Vaccine Therapy With Basiliximab in Treating Patients With Glioblastoma Multiforme That Has Been Removed by Surgery

Overview

RATIONALE: Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Vaccines may help the body build an effective immune response to kill tumor cells. Monoclonal antibodies, such as basiliximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known whether giving chemotherapy, radiation therapy, and vaccine therapy together with basiliximab is a more effective treatment for glioblastoma multiforme than chemotherapy, radiation therapy, and vaccine therapy alone. PURPOSE: This randomized phase I trial is studying the side effects and best way to give chemotherapy and radiation therapy followed by vaccine therapy with basiliximab in treating patients with glioblastoma multiforme that has been removed by surgery.

OBJECTIVES: Primary * To determine if basiliximab inhibits the functional and numeric recovery of T-regulatory cells (Tregs) after therapeutic temozolomide (TMZ)-induced lymphopenia in the context of vaccinating adult patients with newly diagnosed glioblastoma multiforme (GBM) using PEPvIII-keyhole limpet hemocyanin (KLH). Secondary * To evaluate the safety of basiliximab in the context of vaccinating adult patients with newly diagnosed GBM using PEP-3-KLH conjugate vaccine during recovery from therapeutic TMZ-induced lymphopenia. * To determine if basiliximab enhances the magnitude or character of PEPvIII-KLH-induced cellular or humoral immune responses, inhibits or enhances activation-induced cell death, or induces immunologic or clinical evidence of autoimmunity. * To determine if basiliximab enhances the magnitude or character of PEPvIII-KLH-induced cellular or humoral immune responses, inhibits or enhances activation-induced cell death, or induces immunologic or clinical evidence of autoimmunity. * To determine if basiliximab alters the phenotype (CD56-expression), cytokine secretion profile, or cytotoxicity of CD3-negative CD56-positive natural killer cells. * To determine if basiliximab, in addition to vaccination, extend progression-free survival compared to historical cohorts. * To characterize immunologic cell infiltrate in recurrent tumors and seek evidence of antigen escape outgrowth. OUTLINE: * Leukapheresis: Patients undergo leukapheresis over 2-4 hours for immunologic monitoring. * Concurrent standard adjuvant chemoradiotherapy: Patients receive external-beam radiotherapy once daily, 5 days a week, over 6-7 weeks (33 fractions) and concurrent temozolomide by mouth 7 days a week for up to 49 days beginning on the first day and continuing until the last day of radiotherapy. * Temozolomide and PEP-3-KLH conjugate vaccine: Approximately 3 weeks after completion of radiotherapy, patients receive temozolomide by mouth on days 1-21, or on days 1-5 depending on their treating neuro-oncologist, basiliximab IV over 30 minutes on day 21, and PEP-3-KLH conjugate vaccine intradermally on days 21, 35, and 49. Patients then receive a second course of temozolomide by mouth on days 1-21 or days 1-5, depending on their treating neuro-oncologist. Treatment with temozolomide repeats every 4 weeks for 5 additional courses. Patients also receive PEP-3-KLH conjugate vaccine on day 21 of each remaining temozolomide course. Patients then receive the vaccine monthly until disease progression. Patients undergo blood sample collection periodically for laboratory studies. After completion of study therapy, patients are followed periodically.
