Narrative objectives1 This study aims at evaluating the safety of an immunotherapy using WT1-W10 peptide combined with the standard radio-chemotherapy using temozolomide against juvenile diffuse midline glioma. An addition of bevacizumab is permissible, but evaluation will be made separately. As an auxiliary subject of observation includes optimization of dose of the immunogen.

Interventions/Control_1 Standard radio-chemotherapy using wither 1) or 2) below will be combined.

1)Temozolomide (TMZ) + WT1-W10 peptide
2)Temozolomide (TMZ) + bevacizumab (BV) + WT1-W10 peptide

1.WT1-W10 peptide immunotherapy
3.0 mg WT1-W10 peptide in 300micro-l of 5% glucose is mixed with the inactivated 5x108 Bordetella pertussis whole cell vaccine in 100micro-l saline and injected intra-dermally into 4 sites (100micro-l per site) near the sub-clavicular and axial lymph nodes. Immunization is repeated every week. If the erythema which usually emerge 24-48 hours after the immunization, exceed 5 cm in diameter dose of the immunogen will be reduced to 1/2 from the next injection.

By following the standard protocol provided by the manufacturer 75 mg/m2 of TMZ was ingested every day for 5 days a week and for 6 weeks. After 4 weeks of withdrawal, 150 (up to 200) mg/m2 of TMZ was taken every day for 5 days followed by 3 week-withdrawal. This 28-day interval of TMZ administration is repeated.

5 mg/Kg/week of BV was administered intravenously every 2-3 weeks. Synchronization with the schedule of TMZ is not necessary.
