Glioblastoma adaptive, global, innovative learning environment or GBM AGILE trial is to identify effective therapies and improve survival for a type of brian cancer called glioblastoma (GBM) and to match effective therapies with adult patients with newly diagnosed or recurring glioblastoma. Eligible participants will have a 50/50 chance of taking either standard therapy medications or a medication not yet approved by the FDA called regorafenib during their standard of care treatment for GBM.
This study evaluates the safety and usefulness of a new investigational drug called AG-881-C-004 in participants with residual or recurrent Grade 2 glioma (a type of brain cancer) that have a IDH1 or IDH2 mutation. Participants will be randomly assigned to take either the study drug or a placebo (a medically inactive substance). If your disease progresses and you were receiving the placebo, you will be given the opportunity to start taking the study drug.
