GMCI, Nivolumab, Radiation Therapy, and Temozolomide in Treating Patients with Newly Diagnosed High-Grade Gliomas

Trial Status: administratively complete

This phase I trial studies the side effects and best dose of aglatimagene besadenovec and valacyclovir (gene mediated cytotoxic immunotherapy [GMCI]), nivolumab, radiation therapy, and temozolomide in treating patients with newly diagnosed high-grade gliomas. Aglatimagene besadenovec and valacyclovir may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Drugs used in chemotherapy, 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. Giving GMCI, nivolumab, radiation therapy, and temozolomide may work better in treating patients with high-grade gliomas.
