Summary
Brief summary (as posted)
This phase II trial studies how well glembatumumab vedotin works in treating patients with osteosarcoma that has come back (recurrent) or does not respond to treatment (refractory). Monoclonal antibodies, such as glembatumumab vedotin, may find tumor cells and help kill them.
