研究概览
简要总结
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.

结局指标
主要结局
Ability of Peposertib (M3814) to cross the blood brain barrier (Stage II)
时间窗: At 1, 2, and 4 hours after drug administration on fraction day 1 and at pre-dose and 1, 2, and 4 hours after drug administration on fraction day 10
Ability of the investigational drug to cross the blood brain barrier will be tested by measuring concentration of the drug within the blood and the resected brain tumor tissue. This will be correlated with biomarkers of deoxyribonucleic acid (DNA) damage in brain tumor tissue, blood, and hair follicle.
Maximum tolerated dose (MTD) (Stage I)
时间窗: Within the first 10 weeks of study treatment
Will employ the Bayesian optimal interval to find the MTD.
