RATIONALE: 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. 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. Giving these treatments together may kill more tumor cells. Granulocyte Macrophage-Colony Stimulating Factor (GM-CSF) is a powerful adjuvant capable of stimulating macrophage function, inducing proliferation and maturation of DCs, and is able to enhance T-lymphocyte stimulatory function. Intradermal administration of GM-CSF enhances the immunization efficacy at the site of administration PURPOSE: This clinical trial is studying how well basiliximab works in treating patients with newly diagnosed glioblastoma multiforme and temozolomide-caused lymphopenia who are undergoing targeted immunotherapy.

Eligibility | DISEASE CHARACTERISTICS: - Histopathologically confirmed glioblastoma multiforme - WHO grade IV disease - Must undergo leukapheresis = 4 weeks after definitive resection - Residual radiographic contrast enhancement on post-resection CT scan or MRI must not exceed 1 cm in diameter in two perpendicular axial planes - Patients with evidence of contrast enhancement exceeding 1 cm in diameter in two perpendicular axial planes after radiation will not be a candidate for the vaccine despite being previously enrolled and will be removed from the study and replaced - No radiographic or cytologic evidence of leptomeningeal or multicentric disease PATIENT CHARACTERISTICS: - Karnofsky performance status 80-100% - Curran Group status I-IV - Not pregnant or nursing - Negative pregnancy test - Fertile patients must use effective contraception - No active infection requiring treatment - No unexplained febrile (>101.5°F) illness - No known immunosuppressive disease or known HIV infection - No unstable or severe intercurrent medical conditions such as severe heart or lung disease - No allergy to temozolomide (TMZ) or otherwise unable to tolerate TMZ for reasons other than lymphopenia - Patients who are found after enrollment to be unable to tolerate TMZ will not be a candidate for the vaccine despite being previously enrolled and will be removed from the study and replaced - No prior allergic reaction to daclizumab or one of its components PRIOR CONCURRENT THERAPY: - See Disease Characteristics - No prior daclizumab - No other prior conventional therapeutic intervention except for steroids, radiation, or temozolomide - No prior inguinal lymph node dissection, radiosurgery, brachytherapy, or radiolabeled monoclonal antibodies - No concurrent corticosteroids, with the exception of nasal or inhaled steroids, at a dose above physiologic levels - Patients requiring an increase in corticosteroids, with the exception of nasal or inhaled steroids, such that at the time of first vaccination they require a dose above physiologic levels, will be removed from the study and replaced (physiologic dose will be defined as < 2 mg of dexamethasone/day) - Once vaccinations have been initiated, if patients subsequently require increased steroids, they will still be permitted to remain on the study, but every effort will be made to minimize steroid requirements - No prior allogeneic solid organ transplantation |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Functional capacity of CD4+,CD25+, CD127- T-regulatory cells | Functional and quantitative recovery of regulatory T cells is measured during and following study treatment and at the time of tumor progression, which is estimated to be about 26 months from time of diagnosis based on expected progression free survival rates with standard of care therapy. | Approximately 26 months at time of brain tumor progression | |
Secondary | Safety of CMV pulsed pp65 DC vaccines | Number of patients experiencing WHO Grade 3, 4, and 5 adverse events considered possibly, probably, or definitely related to study treatment | 2 months following last vaccine administration | |
Secondary | Effect of basilixiumab on pp65 vaccine | Determine if basiliximab enhances the magnitude or character of pp65-specific vaccine-induced cellular or humoral immune responses, inhibits or enhances activation-induced cell death, or induces immunologic or clinical evidence of autoimmunity | 1 year | |
Secondary | Effect of basilixiumab on immune profiles | Determine if basiliximab alters the phenotype (CD56-expression), cytokine secretion profile, or cytotoxicity of CD3-CD56+ NK cells | 1 year | |
Secondary | Progression-free survival (PFS) | Time in months from the start of study treatment to the date of first progression according to RANO criteria, or to death due to any cause. Patients alive who had not progressed as of the last follow-up had PFS censored at the last follow-up date. Median PFS was estimated using a Kaplan-Meier curve. | 1 year | |
Secondary | Characterize immune cells in recurrent tumors | Characterize immunologic cell infiltrate in recurrent tumors and seek evidence of antigen escape outgrowth | 1 year |
