Defined as the time between date of randomization and unequivocal clinical, cytological or radiological progression confirmed by central review, or death whatever the cause.
Percentage of participants alive and free from progression at 6 months after the diagnosis. The primary analysis for PFS6 is based on the intention to treat (ITT) population, according to treatment arm assignment. PFS6 is estimated using the Kaplan-Meier method with exact confidence intervals for each cohort and arm. Participants with unknown progression status at 6 months are considered failures (i.e., progressed) for the PFS6 analysis.

OS7 is defined as the percentage of participants alive at 7 months after the initiation of the combination of the backbone (i.e., ONC201) with a novel agent given in the maintenance phase of therapy. The primary analysis for OS7 is based on the ITT population, according to treatment arm assignment. OS7 is estimated using the Kaplan-Meier method with exact confidence intervals for each cohort and arm. Participants with unknown survival status at 7 months are considered failures (i.e., dead) for the OS7 analysis.
The safety and tolerability of ONC201 at a previously untested dose will be measured by the proportion of participants reporting a DLT within the first cycle of treatment.
The safety and tolerability of ONC201 in combination with targeted therapies will be measured by the number of participants reporting dose modification during first cycle.
The safety and tolerability of DNX-2401 at Dose Level 1 (5 × 10\^10 viral particles) will be measured by the proportion of participants reporting a DLT.

|---|---|---|
| everolimus | ACTIVE_COMPARATOR | Tablets of 2.5 mg or 10 mg. The prescribed dose is 5 mg/m²/day, orally, once daily. Dose will be capped at 10 mg once daily. Treatment will be continued until unacceptable toxicity, centrally confirmed tumor progression (either radiologically or histologically) and/or withdrawal of patient, parents or legal representative consent. At the time of centrally confirmed relapse or progression, patients will stop treatment and will be allowed to switch to the other arm in case no better option is available after considering the results of the molecular profiling. In case of switch (everolimus to ONC201 or vice-versa), the patient will observe a wash-out period of 7 days before starting: * the second treatment, * or a reirradiation (if applicable). No treatment is allowed during reirradiation, except setroids and bevacizumab. Then, if an additional treatment is needed, the second treatment will be started within one week after the end of the reirradiation. |

ONC201 is an investigational small molecule being studied for the treatment of Diffuse Intrinsic Pontine Glioma (DIPG), a type of brain tumor. It is also being evaluated in related conditions such as Diffuse Midline Glioma with H3 K27M mutations. The drug is currently in Phase 3 clinical development for these indications.
ONC201 targets ClpP, a mitochondrial protease. By acting on this mitochondrial target, the drug is designed to interfere with cancer cell metabolism and promote cell death. This mechanism is being studied in the context of Diffuse Intrinsic Pontine Glioma and other H3 K27M-mutant gliomas.
ONC201 is being developed by Jazz Pharmaceuticals plc, a biopharmaceutical company traded on the NASDAQ under the ticker JAZZ. The company is conducting clinical trials to evaluate the drug's safety and efficacy in patients with Diffuse Intrinsic Pontine Glioma and related conditions.
ONC201 is in Phase 3 clinical development for Diffuse Intrinsic Pontine Glioma. It is an investigational drug and has not been approved by regulatory authorities. The ongoing Phase 3 trial, NCT05476939, is actively recruiting patients to assess the treatment's effectiveness.
ONC201 is being evaluated in two active clinical trials. NCT05476939 is a Phase 3 study enrolling 433 patients with Diffuse Intrinsic Pontine Glioma and Diffuse Midline Glioma in Denmark, France, Spain, and Sweden. NCT05009992 is a Phase 2 trial with 360 participants studying combination therapy for diffuse midline gliomas across multiple countries.
ONC201 is the primary name for this investigational drug. No alternative names have been reported for this compound. It is being studied under this designation in clinical trials for Diffuse Intrinsic Pontine Glioma and related H3 K27M-mutant gliomas.
