• •Clinically significant pericardial/pleural effusion or ascites unless able to be drained before study entry.
• •Presence of third space fluid which cannot be controlled by drainage.
• •Core biopsy/other minor surgical procedure(excluding placement of a vascular access device)within 7 days prior to study enrollment.

Treated brain metastases are defined as having no evidence of progression or hemorrhage after treatment and no ongoing requirement for dexamethasone, as ascertained by clinical examination and brain imaging(MRI or CT)during the screening period.Anticonvulsants(stable dose)are allowed.Treatment for brain metastases may include whole brain radiotherapy(WBRT),radiosurgery(RS;Gamma Knife,LINAC,or equivalent)or a combination as deemed appropriate by the treating physician.Radiotherapy must be completed at least 4 weeks prior to study enrollment and all acute radiotherapy toxicities resolved.Patients with CNS metastases treated by neurosurgical resection or brain biopsy performed within 3 months prior to Day 1 will be excluded.
