Our study highlights the importance of understanding tumor-specific factors that limit CAR T-cell response and using this information to design superior next-generation CAR T-cells. Specifically, we identify cytoskeleton remodeling and T cell motility as therapeutically actionable targets for future engineering approaches.
This study retrospectively applies TIAN criteria to patients with DIPG/pontine DMG treated with intraventricular B7-H3 CAR T cells in the BrainChild-03 (BC-03) trial (NCT04185038)...TIAN was common within this cohort but mostly low-grade and transient. Refining its classification and understanding its clinical impact will aid safety assessments and trial comparisons for CNS-directed CAR T therapies.
