Trial Summary

Will I have to stop taking my current medications?

The trial requires that participants have a stable or decreasing dose of corticosteroids and anti-seizure medications for 7 days before joining. Some medications, like strong CYP3A4 inhibitors and inducers, must be stopped a few days or weeks before starting the trial. The protocol does not specify other medications, so it's best to discuss with the trial team.

What is the purpose of this trial?

This is a randomized, double-blind, placebo-controlled, parallel-group, international, Phase 3 study in patients with newly diagnosed H3 K27M-mutant diffuse glioma to assess whether treatment with ONC201 following frontline radiotherapy will extend overall survival and progression-free survival in this population. Eligible participants will have histologically diagnosed H3 K27M-mutant diffuse glioma and have completed standard frontline radiotherapy.

Eligibility Criteria

This trial is for patients with a new diagnosis of H3 K27M-mutant diffuse glioma who have finished standard radiotherapy. They must understand the study, weigh at least 10 kg, and have stable health status. Exclusions include recent use of certain drugs like Temozolomide or Bevacizumab, evidence of disease spread beyond the brain, abnormal lab results, pregnancy, or any condition that could affect safety or compliance.

Inclusion Criteria

I finished my radiotherapy 2 to 6 weeks ago.
I have had a detailed MRI scan of my brain before starting radiotherapy.
My weight is at least 10 kg.

Trial Overview The ACTION Study tests whether ONC201 can extend survival after radiotherapy in patients with H3 K27M-mutant diffuse glioma. It's a Phase 3 trial where participants are randomly assigned to receive either ONC201 plus placebo or just placebo in a double-blind manner (neither doctors nor patients know who gets the drug).
