Vorinostat and Temsirolimus With or Without Radiation Therapy in Treating Younger Patients With Newly Diagnosed or Progressive Diffuse Intrinsic Pontine Glioma

This phase I trial studies the side effects and best dose of temsirolimus when given together with vorinostat and with or without radiation therapy in treating younger patients with newly diagnosed or progressive diffuse intrinsic pontine glioma, a tumor that arises from the middle portion of the brain stem. Vorinostat and temsirolimus 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. Giving temsirolimus and vorinostat with or without radiation therapy may be a better treatment for younger patients with diffuse intrinsic pontine glioma.
