Summary

This phase II/III trial compares the effect of vincristine, irinotecan, and regorafenib (VIrR) in combination with vincristine, doxorubicin, cyclophosphamide (VDC), ifosfamide and etoposide (IE) to usual treatment with VDC/IE for the treatment of newly diagnosed Ewing sarcoma or other round cell sarcomas that have spread from where they first started (primary site) to other places in the body (metastatic). Vincristine is in a class of medications called vinca alkaloids. It works by stopping tumor cells from growing and dividing and may kill them. Irinotecan is in a class of antineoplastic medications called topoisomerase I inhibitors. It blocks a certain enzyme needed for cell division and deoxyribonucleic acid (DNA) repair and may kill tumor cells. Regorafenib, a type of kinase inhibitor and a type of antiangiogenesis agent, blocks certain proteins, which may help keep tumor cells from growing. It may also prevent the growth of new blood vessels that tumors need to grow. Doxorubicin is in a class of medications called anthracyclines. Doxorubicin damages the cell's DNA and may kill tumor cells. It also blocks a certain enzyme needed for cell division and DNA repair. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill tumor cells. It may also lower the body's immune response. Ifosfamide, a type of alkylating agent and a type of antimetabolite, attaches to DNA in cells and may kill tumor cells. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill tumor cells. Giving VIrR/VDC/IE may be more effective than usual treatment with VDC/IE in treating patients with newly diagnosed metastatic Ewing sarcoma or other round cell sarcomas.
