We report results of strata 2, 5, and 6 with updated survivals for strata 1, 3, and 4.Stratum 2 included recurrent/progressive pilocytic astrocytoma (PA) not associated with neurofibromatosis type-1 (NF1) that screened negative for the BRAF-KIAA1549 fusion and BRAFV600E mutation. Stratum 5 enrolled non-PA that screened positive for one of the BRAF aberrations. Stratum 6 enrolled children who consented to tissue screening, but there was an assay failure. For long-term survivals, stratum 1 included non-NF1 PA positive for one of the BRAF aberrations; stratum 3 included NF1-associated pLGG; and stratum 4 included non-NF1 optic pathway/hypothalamic tumors.Stratum 2: among 14 evaluable patients, there was 1 partial response (PR), 7 stable disease (SD) and 6 progressive disease (PD); overall response rate (ORR) was 7.1 %K Recurrent (Other) %K and MEK inhibitor (Other) %K pediatric low-grade glioma (pLGG) (Other) %K selumetinib (Other) %F PUB:(DE-HGF)16 %9 Journal Article %$ pmid:40241281 %R 10.1093/neuonc/noaf065 %U https://inrepo02.dkfz.de/record/300575
