New pilot study aims to personalize glioma treatment with drug cocktails

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria - Treatment Arm (Regimens 1-8): * Age ≥ 18 years * Prior diagnosis of a glioma treated with chemotherapy and/or radiation with stable disease based on Response Assessment in Neuro-Oncology (RANO) criteria * Must have IDH-mutant OR MGMT-methylated glioma * NOTE: Patients with any radiographic evidence of residual disease are eligible * Eastern Cooperative Oncology Group (ECOG) of 0, 1, or 2, and Karnofsky performance status \>= 50 * Hemoglobin ≥ 9.0 g/dL (≤ 15 days prior to registration) * Absolute neutrophil count (ANC) ≥ 1500/mm\^3 (≤ 15 days prior to registration) * Platelet count ≥ 100,000/mm\^3 (without transfusion ≤ 7 days preceding lab assessment) (≤ 15 days prior to registration) * Alanine aminotransferase (ALT) and aspartate transaminase (AST) ≤ 2.5 x upper limit of normal (ULN) (or ≤ 5 x ULN for patients with liver involvement) (≤ 15 days prior to registration) * Calculated creatinine clearance ≥ 45 ml/min using the Cockcroft-Gault formula (≤ 15 days prior to registration) * Average corrected QT interval (QTc) ≤ 450 ms on triplicate 12 lead electrocardiogram (ECG) ≤ 29 days prior to registration * NOTE: QTc intervals will be corrected using Fridericia's formula (Fridericia 1920) * Negative serum pregnancy test is required for persons of childbearing potential ≤ 8 days prior to registration * Presence of an implanted cranial CSF access device, such as Ommaya reservoir or ventriculoperitoneal shunt * Willingness to provide blood and CSF samples for research * Co-enrollment on the neuro-oncology biorepository \[institutional review board (IRB) 12-003458\] for collection of research blood and CSF samples * Provide written informed consent * Willingness to return to Mayo Clinic for follow-up Inclusion Criteria - Monitoring Arm (Regimen 1 only): * Age ≥ 18 years * Prior diagnosis of a glioma * Negative serum pregnancy test is required for persons of childbearing potential ≤ 8 days prior to registration * Co-enrollment on the neuro-oncology biorepository \[institutional review board (IRB) 12-003458\] for collection of research blood and CSF samples * Provide written informed consent * Willingness to return to Mayo Clinic for follow-up Exclusion Criteria - Treatment Arm (Regimens 1-8): * Any of the following because this study involves an agent that has known genotoxic, mutagenic and teratogenic effects: * Pregnant persons * Nursing persons * Persons of childbearing potential and persons able to father a child who are unwilling to employ adequate contraception * Patients who are not appropriate medical candidates due to current or past medical history or uncontrolled concurrent illness which limits safety of or compliance to study proceedings * Participants who are unable to swallow tablets or who are at risk for impaired absorption of oral medication * NOTE: This includes but not limited to, refractory vomiting, gastric resection/bypass, or duodenal/jejunal resection * NOTE: An exception can be granted for such patients if no oral medications are planned (i.e., patient will receive only IV or intradermal agents) * Patients with known hypersensitivity or allergy to all of the study drugs on the protocol (known hypersensitivity or allergy to one drug does not preclude participation in this protocol) * Inability to undergo MRI scans * NOTE: These patients may be enrolled in the Monitoring Arm Exclusion Criteria - Monitoring Arm (Regimen 1 only): * Any of the following because this study involves an agent that has known genotoxic, mutagenic and teratogenic effects: * Pregnant persons * Nursing persons * Persons of childbearing potential and persons able to father a child who are unwilling to employ adequate contraception * Current or past medical history or uncontrolled concurrent illness which limits safety or compliance with study proceedings * Known hypersensitivity or allergy to radioactive tracers * Inability to undergo clinical imaging
