8. Active seizure disorder or evidence of brain metastases, spinal cord compression, or carcinomatous meningitis.
• Patients with clinical evidence suggestive of new brain metastases are excluded if brain metastases have not been ruled out using CT or MRI imaging.
• Patients with previously diagnosed brain metastases are eligible if they have completed their radiation therapy to the central nervous system (CNS) and have recovered from the acute effects of that treatment prior to enrollment, have discontinued corticosteroid treatment for these metastases for at least 2 weeks, and are neurologically stable.
