Testing AZD1775 inC Combination With Radiotherapy and Chemotherapy in Cervical, Upper Vaginal and Uterine Cancers

This phase I trial studies the side effects and best dose of adavosertib when given together with external beam radiation therapy and cisplatin in treating patients with cervical, vaginal, or uterine cancer. Adavosertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. External beam radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as cisplatin, 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 adavosertib, external beam radiation therapy, and cisplatin may work better in treating patients with cervical, vaginal, or uterine cancer.
