VSV-hIFNbeta-NIS With or Without Ruxolitinib Phosphate in Treating Stage IV or Recurrent Endometrial Cancer

This phase I trial studies the side effects and best dose of vesicular stomatitis virus-human interferon beta-sodium iodide symporter (VSV-hIFNbeta-NIS) with or without ruxolitinib phosphate in treating patients with stage IV endometrial cancer or endometrial cancer that has come back. The study virus, VSV-hIFNbeta-NIS, has been changed so that it has restricted ability to spread to tumor cells and not to healthy cells. It also contains a gene for a protein, NIS, which helps the body concentrate iodine making it possible to track where the virus goes. VSV-hIFNbeta-NIS may be able to kill tumor cells without damaging normal cells. Ruxolitinib phosphate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving VSV-hIFNbeta-NIS with ruxolitinib phosphate may work better in treating patients with endometrial cancer compared to VSV-hIFNbeta-NIS alone.
