• Life expectancy of less than 12 weeks
• Current, recent (within 4 weeks of the first infusion of this study), or planned participation in an experimental drug study other than a Genentech-sponsored bevacizumab cancer study
• Active malignancy, other than superficial basal cell and superficial squamous (skin) cell, or carcinoma in situ of the cervix within last five years

Bevacizumab-Specific Exclusions

• 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.

• History of hemoptysis (>= 1/2 teaspoon of bright red blood per episode) within 1 month prior to Day 1
• Evidence of bleeding diathesis or significant coagulopathy (in the absence of therapeutic anticoagulation)
• Major surgical procedure, open biopsy, or significant traumatic injury within 28 days prior to Day 1 or anticipation of need for major surgical procedure during the course of the study
• Core biopsy or other minor surgical procedure, excluding placement of a vascular access device, within 7 days prior to Day 1
• History of abdominal fistula or gastrointestinal perforation within 6 months prior to Day 1
• Serious, non-healing wound, active ulcer, or untreated bone fracture
• Proteinuria as demonstrated by a UPC ratio >= 1.0
• Known hypersensitivity to any component of bevacizumab
• Pregnancy (positive pregnancy test) or lactation. Use of effective means of contraception (men and women) in subjects of child-bearing potential
• History of abdominal fistula or intra-abdominal abscess within 6 months prior to start.
