- Patients with untreated brain metastases, untreated spinal cord compression or meningeal metastases are not eligible (CT scans are not required to rule this out unless there is a clinical suspicion of CNS disease). Patients with treated brain metastases who have radiologic evidence of stable brain metastases, with no evidence of cavitation or hemorrhage in the brain lesion, are eligible providing that they are asymptomatic and do not require corticosteroids (must have discontinued steroids at least 1 week prior to randomization).
