6 • H3 K27M mutation is predominantly found among diffuse midline gliomas (DMGs) in young adults and children • Frontline radiotherapy remains standard of care with transient benefit; resection often not feasible • DMGs harboring the H3 K27M mutation are WHO Grade IV; historically invariably lethal • Studies consistently indicate longer OS of ONC201 - treated glioma patients relative to diverse external controls H3 K27M - mutant diffuse glioma: high unmet need Natural Disease History: Recurrent H3 K27M and/or DMG 3 (n=43) ONC201 Phase 2: Recurrent H3 K27M DMG (n=50) Median OS,mo (95% CI) 5.1 (3.9 - 7.7) 13.7 (8 - 20.3) OS @ 12mo (95% CI) 23.6% (11.7 - 37.9) 57% (41 - 70) OS @ 24mo (95% CI) 11.1% (3.3 - 24.2) 35% (21 - 49) No ONC201 (n=274): 12mo mOS P=0.05 P<0.0001 No ONC201 (n=99): 8.1mo mOS Histone H3 Mutations in CNS Tumors 1 Recurrent H3 K27M DMG Frontline H3 K27M DMG ONC201 (n=37): 16.2mo mOS ONC201 (n=35): 26.3mo mOS External analysis reported at SNO 2022 2 Company Sponsored Studies 1 Lulla RR et al.

7 • Strict selection criteria to ensure responses attributable to single agent treatment • Responses require both imaging and clinical criteria • Dual reader blinded independent central review (BICR) • Growing consensus that assessment of enhancing and non - enhancing disease (RANO - HGG and RANO - LGG criteria) is needed for diffuse midline glioma ONC201 waterfall plot – 30% RANO HGG / LGG response RANO HGG (enhancing) • 20% response • 40% disease control RANO LGG (non - enhancing) • 26% response • 42% disease control ONC201 Ph 2 Efficacy Analysis by BICR in Recurrent H3 K27M - mutant Diffuse Midline Glioma

ONC201 Phase 3 ACTION Study Summary



12 Now enrolling, a randomized, double - blind, placebo - controlled, multicenter international study in 450 newly diagnosed diffuse glioma patients whose tumor harbors an H3 K27M - mutation. Pivotal Phase 3 ACTION trial design 1. Excludes DIPG and spinal tumors • H3 K27M - mutant diffuse glioma 1 • Radiation therapy recently completed • KPS > 70 at time of randomization • Stable steroid dose • No prior bevacizumab • No temozolomide within three weeks ONC201 twice weekly (625mg ONC201 day 1 + day 2) ONC201 weekly (625mg ONC201 day 1 + placebo day 2) Placebo (Placebo day 1 + placebo day 2) • Primary: Overall Survival • PFS (alpha - allocated) • Secondary: steroid response, performance status, QoL, neurologic function Key Patient Inclusion Endpoints Treatment



13 Multiple unique aspects to ONC201 data support translation to phase 3 success Isolated, durable single agent activity Consistency across multiple endpoints Enhanced activity not required, but likely • Responses not confounded by combination treatments • Responses were gradual, durable, and multi - focul • Responses observed via most stringent criteria in blinded assessment • Earlier setting associated with higher response rate (performance status, tumor volume) • Addition of higher - dose study arm • Biomarker selection supports patient homogeneity • Responses highly associated with other forms of clinical benefit • PFS and OS favorable to historical benchmarks • Multiple separate analyses suggest longer survival of patients who received ONC201



14 Design provides multiple paths for success Interim data expected in early 2025 and final data in 2026 Second OS Interim • ~246 events • Success at HR=0.64 Final OS • ~327 events • Success at HR=0.73 PFS by RANO HGG (2) • ~286 events • Success at HR=0.68 1. Overall Survival (OS) 2. Progression - free survival (PFS). PFS may provide valuable data for regulatory discussions. 3. Hazard Ratio Independent comparisons for each ONC201 arm versus control will be made at each timepoint. Powering assumptions 0.65 expected HR for OS and 0.60 expected HR for PFS First OS (1) Interim • ~164 events • Success at HR (3) =0.52



15 • No approved therapies for H3 K27M mutant glioma, ONC201 is the leading program targeting this mutation globally • Potential market opportunity up to ~$750 million • Approximately 5,000 patients in top seven markets • Ultra - orphan indication drug pricing • H3 K27M mutations most often in children / young adults (little to no exposure to Medicare) • Low barriers to adoption - No effective alternative therapies - High unaided awareness among neuro - oncologists - Mutation routinely identified by existing diagnostics - Longer - term, potentially combinable with other glioma therapies • Patent protection for lead indication into 2037 - potential U.S. patent term extension (up to five years) H3 K27M - mutant glioma: rapid ramp to peak revenue expected
