Glioma Clinical Trial
Official title:
Studying the Biology of IDH-mutant Gliomas Via Longitudinal Observation of 2-Hydroxyglutarate (2-HG) Using MR Spectroscopy
Background: Glioma is a type of brain cancer. Some of these tumors have gene mutations. These mutations can cause a substance called 2-HG to build up in the brain. This makes the tumors more aggressive. Researchers want to better understand 2-HG buildup in the brain. They hope this can help them design better ways to test for gliomas. Objective: To monitor the level of 2-HG in the brains of people with gliomas that have mutations in the IDH1 or IDH2 genes. Eligibility: People ages 18 and older with gliomas with mutations in the IDH1 or IDH2 genes Design: Participants will be screened with: Medical and cancer history Physical exam Reviews of their symptoms and ability to perform normal activities Blood and urine tests MRI scan Samples of their tumor from a past surgery Documentation of their diagnosis and mutation status Participants will have an initial evaluation. This will include repeats of screening tests. It will also include: Neurological exam MRS and MRI scans of the brain: Participants will lie on a table that slides into a metal cylinder. A coil or soft padding will be placed around their head. They will have a contrast agent injected into a vein. Pictures will be taken of the brain. Participants will have follow-up visits every 2-6 month for the rest of their life. Visits will include scans.

Eligibility | - INCLUSION CRITERIA: - Patients must have histologically confirmed glioma with IDH1 or IDH2 mutation confirmed by DNA sequencing. - Patients must have grade II, III or IV glioma. - Patients must have measurable disease. - Age greater than or equal to18 years. Tumor biology of IDH-mutant gliomas are different in pediatric tumors. Therefore, children will be excluded from the study. - Karnofsky performance greater than or equal to 60%. - Patients must have normal kidney function as defined below: - creatinine within normal institutional limits OR - creatinine clearance greater than or equal to 60 mL/min/1.73 m(2) for patients withcreatinine levels above institutional normal (Measured or calculated creatinine clearance (GFR can also be used in place of creatinine or CrCl)). - Ability of subject or Legally Authorized Representative (LAR) to understand and the willingness to sign a written informed consent document. EXCLUSION CRITERIA: - Subjects with any coexisting medical or psychiatric condition that is likely to interfere with study procedures and/or results (such as allergy to gadolinium contrast, metal implants and so on). - Pregnant women are excluded because MRI contrast, planned to be used on this study, may be dangerous for the fetus. Because there is an unknown but potential risk for adverse events in nursing infants secondary to using of MRI c ntrast, breastfeeding should be discontinued for 72 hours following study imaging. |

Primary | To monitor the quantitative levels of 2-hydroxyglutarate (2-HG) longitudinally in patients with IDH mutant gliomas via proton magnetic resonance spectroscopy (1H-MRS) | Changes in the level of 2-HG correlate with the occurrence of higher-grade transformation (HT) and/or development of hypermutator phenotype (HMP) in patients with IDH-mutant gliomas | 5 years | |
Secondary | Determine the utility of 2-HG detection by 1H-MRS to predict higher-grade transformation (HT) and hypermutator phenotype (HMP) by correlating the 2-HG level with pathological diagnosis and tumor mutational load of the tumor tissue at time of rec... | Usefulness of 2-HG detection and its correlation with high grade transformation and HMP | at clinical disease recurrence |
