简要总结
RATIONALE: Vaccines made from a peptide may help the body build an effective immune response to kill tumor cells. Colony-stimulating factors, such as GM-CSF, increase the number of white blood cells and platelets found in bone marrow or peripheral blood. Giving vaccine therapy after surgery may kill any tumor cells that remain after surgery.
PURPOSE: This phase II trial is studying how well vaccine therapy works in treating patients with newly diagnosed glioblastoma multiforme.
详细描述
OBJECTIVES:
Primary
- To assess humoral and cellular immune responses to adjuvant PEP-3-KLH conjugate vaccine in patients with newly diagnosed glioblastoma multiforme (GBM).
- To assess the clinical efficacy of the PEP-3-KLH conjugate vaccine, in terms of progression-free survival, in patients with newly diagnosed GBM.
Secondary
- To determine whether patients with GBM, who are known to be at least mildly immunosuppressed, can respond to standard and proven vaccine strategies.
- To assess for any potential toxicity to the PEP-3-KLH conjugate vaccine in patients with newly diagnosed GBM.

研究组 & 干预措施
Arm I (ACTIVATE)
Patients first receive 3 initial vaccinations of an epidermal growth factor receptor variant III (EGRRvIII)-specific peptide (PEP-3) keyhole limpet hemocyanin (KLH) conjugate vaccine and sargramostim (GM-CSF), referred to as PEP-3 vaccine, every 2 weeks starting 4 weeks after the completion of radiation. Subsequent vaccinations were given once a month until clinical or radiographic evidence of progression or death.

结局指标
主要结局
Humoral and Cellular Immune Response
时间窗: 26 months
Number of patients that developed a delayed-type hypersensitivity (DTH) response at following vaccination. Any skin reaction in response to the intradermal injection of the antigen was measured and recorded. A positive skin test was defined as \> 5 mm induration (swelling).
Clinical Efficacy of Vaccination, in Terms of Progression-free Survival (PFS)
时间窗: 58 months
Time in months from the start of study treatment to the date of first progression according to Macdonald 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. Macdonald criteria are standard criteria in neuro-oncology. Tumor assessment was made according to the adapted MacDonald criteria based on the combined evaluation of: 1) assessment of the MRI scan for measurable, evaluable, and new lesions (made by the independent external expert too), 2) overall assessment of neurological performance (made by the investigator), 3) concomitant steroid use (as reported by the investigator).
次要结局
- Response to Vaccination(26 months)
- Toxicity to PEP-3 Vaccine Immunization(26 months)
