- Participants with inadequately controlled hypertension
- Prior history of hypertensive crisis or hypertensive encephalopathy
- Participants with significant vascular disease within 6 months prior to Screening
- Participants with a history of hemoptysis within 1 month prior to Screening
- Current use of full-dose oral or parenteral anticoagulants or thrombolytic agents for therapeutic purposes
- Core biopsy or other minor surgical procedure, excluding placement of a vascular access device, within 7 days prior to the first dose of bevacizumab
- Participants with a history of abdominal or trache-oesophageal fistula or gastrointestinal (GI) perforation within 6 months prior to Screening
- Participants with clinical signs of GI obstruction or requirement for routine parenteral hydration, parenteral nutrition, or tube feeding
- Participants with evidence of abdominal free air not explained by paracentesis or recent surgical procedure
