Subjects with spinal cord compression or active brain metastases, except for subjects with untreated and asymptomatic brain metastases or with stable brain metastases after treatment.
Subjects with pleural effusion, pericardial effusion, or ascites requiring repeated drainage.
Subjects whose imaging shows that the tumor has invaded important blood vessels or the investigator judges that the tumor is very likely to invade important blood vessels and cause fatal bleeding during the study.
