Gliosarcoma clinical trials at UC Irvine

This randomized phase II trial studies how well dose-escalated photon intensity-modulated radiation therapy (IMRT) or proton beam radiation therapy works compared with standard-dose radiation therapy when given with temozolomide in patients with newly diagnosed glioblastoma. Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells and shrink tumors. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs, such as temozolomide, may make tumor cells more sensitive to radiation therapy. It is not yet known whether dose-escalated photon IMRT or proton beam radiation therapy is more effective than standard-dose radiation therapy with temozolomide in treating glioblastoma.

This phase II clinical trial studies how well ERC1671 plus Granulocyte-macrophage colony-stimulating factor (GM-CSF) plus Cyclophosphamide with Bevacizumab works compared to Placebo Injection plus Placebo Pill with Bevacizumab in treating patients with recurrent/progressive, bevacizumab naïve glioblastoma multiforme and gliosarcoma (World Health Organization (WHO) grade IV malignant gliomas, GBM).

This phase II/III trial compares the usual treatment with radiation therapy and temozolomide to radiation therapy in combination with immunotherapy with ipilimumab and nivolumab in treating patients with newly diagnosed MGMT unmethylated glioblastoma. Radiation therapy uses high energy photons to kill tumor and shrink tumors. Chemotherapy drugs, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Temozolomide, may not work as well for the treatment of tumors that have the unmethylated MGMT. Immunotherapy with monoclonal antibodies called immune checkpoint inhibitors, such as ipilimumab and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. It is possible that immune checkpoint inhibitors may work better at time of first diagnosis as opposed to when tumor comes back. Giving radiation therapy with ipilimumab and nivolumab may lengthen the time without brain tumor returning or growing and may extend patients' life compared to usual treatment with radiation therapy and temozolomide.
