Stage IVA Cervical Cancer AJCC v8

This phase I/II trial tests the safety and tolerability of an experimental personalized vaccine when given by itself and with pembrolizumab in treating patients with solid tumor cancers that have spread to other places in the body (advanced). The experimental vaccine is designed target certain proteins (neoantigens) on individuals' tumor cells. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving the personalized neoantigen peptide-based vaccine with pembrolizumab may be safe and effective in treating patients with advanced solid tumors.

This phase I trial studies the side effects and best dose of talazoparib in combination with radiation therapy and to see how well they work in treating patients with gynecologic cancers that have come back after previous treatment (recurrent). Talazoparib 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 talazoparib in combination with radiation therapy may work better in treating patients with gynecologic cancers.

This study collects information and data on patients with neuroendocrine cervical cancer. Information from this study may be used to better understand the correlation between clinical data, such as patient characteristics, treatment, and disease outcomes, and overall patient outcomes.
