Alliance A091401 – Temporary Closed

This randomized phase II trial studies how well nivolumab with or without ipilimumab works in treating patients with sarcoma that has spread from the primary site to other parts of the body or cannot be removed by surgery. Monoclonal antibodies, such as nivolumab and ipilimumab, may block tumor growth in different ways by targeting certain cells. It is not yet known whether nivolumab works better with or without ipilimumab in treating patients with metastatic or unresectable sarcoma.

COG AEWS1221

This randomized phase III trial studies how well combination chemotherapy with or without ganitumab works in treating patients with newly diagnosed Ewing sarcoma that has spread to other parts of the body. Monoclonal antibodies, such as ganitumab, may block tumor growth in different ways by targeting certain cells. Drugs used in chemotherapy, such as vincristine sulfate, doxorubicin hydrochloride, cyclophosphamide, ifosfamide, and etoposide, 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. It is not yet known whether combination chemotherapy is more effective with or without ganitumab in treating patients with newly diagnosed Ewing sarcoma.

COG ARST1321 – Temporarily closed to accrual

This randomized phase II/III trial studies how well pazopanib hydrochloride, combination chemotherapy, and radiation therapy work and compares it to radiation therapy alone or in combination with pazopanib hydrochloride or combination chemotherapy in treating patients with newly diagnosed non-rhabdomyosarcoma soft tissue sarcomas that can be removed by surgery. Radiation therapy uses high energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as ifosfamide and doxorubicin hydrochloride, 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. Pazopanib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether radiation therapy works better when given with or without combination chemotherapy and/or pazopanib hydrochloride in treating patients with non-rhabdomyosarcoma soft tissue sarcomas.
