• No history of brain metastases.
• No current congestive heart failure (defined as New York Heart Association Class II, III, or IV).
• Well-controlled blood pressure. Those with a history of hypertension should be well-controlled on a regimen of anti-hypertensive medication (exclude if BP>150/100).

• No history of gastrointestinal perforation, intraabdominal fistula, or intraabdominal abscess within 6 months of protocol enrollment.
• No history of arterial thrombotic events within 6 months of protocol enrollment.
• No active serious non-healing wound, ulcer, or bone fracture.
• Eastern Cooperative Oncology Group (ECOG) performance status between 0 and 1.

• Serious concurrent uncontrolled medical disorder.
• Disease for whom corticosteroids are contraindicated such as an active peptic ulcer or uncontrolled diabetes. Patients with controlled diabetes may be considered but must be made aware that their diabetic medications may require adjustment.
• Received prior treatment with a tyrosine kinase inhibitor, estimated glomerular filtration rate inhibitor (EGFR), or vascular endothelial growth factor (VEGF) inhibitor. For the phase II trial, patients who have had previous cytotoxic therapy will not be eligible.
• Currently or have recently participated in a clinical trial (within 4 weeks from the first day of treatment) or are receiving investigational therapies.
