7. Requirement for therapeutic anticoagulant therapy including daily
aspirin (>325 mg/day) or non steroidal anti inflammatory agents known
to inhibit platelet function. Low dose anti coagulants such as low dose
heparin or 1-2 mg/day of warfarin for prevention of deep vein
thrombosis or maintenance of patency of central venous devices is
permitted.
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
