Study Summary

This phase I trial investigates the side effects and best dose of Peposertib, and to see how well it works in combination with radiation therapy in treating patients with newly diagnosed MGMT unmethylated glioblastoma or gliosarcoma. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Peposertib may further stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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 Peposertib with radiation therapy may work better than radiation therapy alone in treating patients with glioblastoma or gliosarcoma.

Primary Outcome

Will employ the Bayesian optimal interval to find the MTD.
