About this study

This phase 1b trial studies the side effects and best dose of telaglenastat in combination with radiation therapy and temozolomide in treating patients with IDH-mutated diffuse or anaplastic astrocytoma. Telaglenastat 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. 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. Giving telaglenastat with radiation therapy and temozolomide may work better than surgery, radiation therapy, and temozolomide in treating patients with IDH-mutated diffuse astrocytoma or anaplastic astrocytoma.
