H3.3K27M Peptide Vaccine With Nivolumab for Children With Newly Diagnosed DIPG and Other Gliomas

Brief description of study

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 H3.3.K27M epitope given in combination with poly-ICLC and the H3.3.K27M epitope given in combination with poly-ICLC and the PD-1 inhibitor, nivolumab, in HLA-A2 (02:01)+ children with newly diagnosed DIPG or other midline gliomas that are positive for H3.3K27M.

Detailed Study Description

Subjects who are eligible will receive a specific peptide vaccine, along with a helper drug called poly-ICLC, in combination with nivolumab, every 3 weeks for the first 6 months of treatment. Subjects will be monitored routinely by laboratory assessments, physical evaluation, vital signs, and MRI. Subjects who tolerate therapy well and have stable or improved disease after 6 months of treatment can continue to receive treatment, nivolumab continuing every 3 weeks but vaccine and poly-ICLC now every 6 weeks, for a total of 96 weeks of treatment.
