This phase II trial studies how well vismodegib and focal adhesion kinase (FAK) inhibitor GSK2256098 work in treating patients with meningioma that is growing, spreading, or getting worse. Vismodegib and FAK inhibitor GSK2256098 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

This phase II trial compares the safety, side effects and effectiveness of anti-lag-3 (relatlimab) and anti-PD-1 blockade (nivolumab) to standard of care lomustine for the treatment of patients with glioblastoma that has come back after a period of improvement (recurrent). Giving relatlimab and nivolumab may be safe, tolerable, and/or effective compared to standard of care lomustine in treating patients with recurrent glioblastoma.

This phase III trial compares the effect of vorasidenib to placebo in combination with usual treatment, temozolomide, in treating patients with newly diagnosed grade 3 astrocytoma after radiation. Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid and may kill tumor cells and slow down or stop tumor growth. Vorasidenib citrate blocks the proteins made by the mutated IDH1 and IDH2 genes, which may help keep tumor cells from growing. It is a type of enzyme inhibitor and a type of targeted therapy. Adding vorasidenib to the usual treatment, temozolomide, may be more effective than temozolomide alone in treating patients with newly diagnosed grade 3 astrocytoma after radiation therapy.

CCTG CE.7

This phase III trial studies stereotactic radiosurgery to see how well it works compared to hippocampus avoidance whole-brain radiation therapy with memantine in treating patients with 5-15 brain tumors that have spread from other places in the body. Stereotactic radiosurgery is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may cause less damage to normal tissue. Hippocampus avoidance whole-brain radiation therapy delivers radiation to the entire brain except for the hippocampus. The hippocampus is a brain structure that is important for memory. Hippocampus avoidance during whole-brain radiation therapy decreases the amount of radiation that is delivered to this area. Memantine is often given with whole brain radiation therapy and may decrease the risk of cognitive side effects after radiation therapy to the brain. It is not yet known whether stereotactic radiosurgery or whole-brain radiation therapy works better in treating patients with 5-15 brain metastases.

NRG-BN003

This randomized phase III trial studies how well radiation therapy works compared with observation in treating patients with newly diagnosed grade II meningioma that has been completely removed by surgery. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors.

NRG-BN013

This phase III trial compares the effectiveness of fractionated stereotactic radiosurgery (FSRS) to usual care stereotactic radiosurgery (SRS) in treating patients with cancer that has spread from where it first started to the brain. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. FSRS delivers a high dose of radiation to the tumor over 3 treatments. SRS is a type of external radiation therapy that uses special equipment to position the patient and precisely give a single large dose of radiation to a tumor. FSRS may be more effective compared to SRS in treating patients with cancer that has spread to the brain.

NRG-BN014

This phase III trial compares proton craniospinal irradiation (pCSI) to involved-field radiation therapy (IFRT) for the treatment of breast or non-small cell lung cancer that has spread from where it first started to the cerebrospinal fluid filled space that surrounds the brain and spinal cord (leptomeningeal metastasis). Patients with leptomeningeal metastasis (LM) may develop multiple areas of nervous system (neurologic) impairment that can be life-threatening. Radiation therapy (RT) effectively relieves local symptoms due to LM. RT uses high energy radiography (x-rays), particles, or radioactive seeds to kill cancer cells and shrink tumors. IFRT is commonly used to treat symptoms of LM. IFRT is radiation treatment that uses x-rays to treat specific areas of LM and to relieve and/or prevent symptoms. pCSI uses protons that can be directed with more accuracy than x-rays which allows treatment of the entire central nervous system space containing the cerebrospinal fluid (CSF), brain, and spinal cord. The pCSI treatment could delay the worsening of LM. Giving pCSI may be better than IFRT in treating LM in patients with breast or non-small cell lung cancer.
