Actual (reported)This is 3-arm, multicenter study that will be conducted through the Pacific Pediatric Neuro-oncology Consortium (PNOC). This study will assess the safety and immune activity of a synthetic peptide vaccine specific for the Histone 3 lysine27-to-methionine (H3.3K27M) epitope given in combination with poly-ICLC and the H3.3K27M epitope given in combination with poly-ICLC and the PD-1 inhibitor, nivolumab, in HLA-A2 (02:01)+ children with newly diagnosed diffuse intrinsic pontine glioma (DIPG) or other midline gliomas that are positive for H3.3K27M.

Actual (reported)Percentage of Participants With Adverse Events (AE) Related to Treatment
Safety of the vaccine (Strata A and B) or vaccine in combination with nivolumab (Stratum C) will be assessed for participants who received the vaccination. The severity of toxicities will be graded according to the NCI Common Terminology Criteria for Adverse Events (CTCAE)version 5.0. and include any clinically-significant lab abnormalities meeting Grade 3, 4, or 5 criteria according to CTCAE. Grade 1 \& 2 AEs will be summarized if probably, possible, or definitely related to study therapy. Descriptive statistics will be utilized to display the data on toxicity reported by participants.
24 months
Overall Survival Rate at 12 Months (OS12) (Stratum A Only)
OS12 is defined as the percentage of participants still alive at 12 months, and is the clinical efficacy, primary endpoint for Stratum A. Any eligible participant that received at least one dose of the K27M/TT vaccine will be considered evaluable for clinical efficacy. OS12 will be censored at the last contact date and estimated using the Kaplan-Meier method.
12 months
Newly diagnosed children with diffuse intrinsic pontine glioma who are positive for HLA-A2 and the H3.3K27M mutation that underwent radiation therapy will receive the specific H3.3K27M peptide vaccine, combined with the tetanus toxoid (TT) peptide, emulsified in Montanide. Poly-ICLC, which is a synthetic nucleic acid, will be given concurrently to improve the therapeutic effects of the vaccine. Vaccine will be given every 3 weeks for the first 24 weeks, then if there is stable or improved disease, will be given every 6 weeks for a total treatment period of 96 weeks.
Newly diagnosed children with gliomas other than DIPG who are positive for HLA-A2 and the H3.3K27M mutation that underwent radiation therapy will receive the specific H3.3K27M peptide vaccine, combined with the tetanus toxoid peptide, emulsified in Montanide. Poly-ICLC, which is a synthetic nucleic acid, will be given concurrently to improve the therapeutic effects of the vaccine. Vaccine will be given every 3 weeks for the first 24 weeks, then if there is stable or improved disease, will be given every 6 weeks for a total treatment period of 96 weeks.

Actual (reported)Newly diagnosed children with DIPG or other midline gliomas (excluding primary spinal cord tumors) who are positive for HLA-A2 (02:01) and the H3.3K27M mutation that underwent radiation therapy will receive the specific H3.3K27M peptide vaccine, combined with the tetanus toxoid peptide, emulsified in Montanide. Poly-ICLC, which is a synthetic nucleic acid, will be given concurrently to improve the therapeutic effects of the vaccine. Nivolumab will also be given via IV. Vaccine will be given every 3 weeks for the first 24 weeks, then if there is stable or improved disease, will be given every 6 weeks for a total treatment period of 96 weeks. Nivolumab will continue to be given every 3 weeks throughout all of treatment.
