Patients must have documented "failure" of prior therapy as defined in the protocol
Patients are eligible after first line platinum based chemotherapy if their disease has relapsed and they have primary mediastinal non seminomatous germ cell tumor (PMNSGCT) or late relapse (> 2 years) not amenable to surgical resection
