Contains supplementary data and table titles and as well as supplementary figures with associated titles and legends. Fig. S1. Selection method for planned efficacy analysis of ONC201 in patients with H3K27MDMG. Fig. S2. Progression-free survival from diagnosis of trial patients with non-recurrent H3K27MDMG treated with ONC201. Fig. S3. Swimmers’ plot of ONC201 response by recurrence status, tumor location, and ONC201 trial. Fig. S4. ONC201 efficacy is independent of TP53 mutation status and chromosomal instability. Fig. S5. Cox proportional hazard regression to assess the effect of ONC201 after adjusting for confounders. Fig. S6. Survival of patients with H3K27M-DMG treated with ONC201 versus ONC201untreated historical controls. Fig. S7. Survival of patients with H3K27M-DMG treated with ONC201 versus ONC201untreated patients (PNOC003 or HERBY Phase II trials). Fig. S8.
