Bevacizumab in Treating Patients With Advanced Solid Tumors

DISEASE CHARACTERISTICS:

• Histologically confirmed solid tumor
• Metastatic or unresectable disease
• Standard curative or palliative measures do not exist or are no longer effective OR treatment with standard chemotherapy plus bevacizumab is appropriate* NOTE: *It must be judged clinically appropriate by the treating physician to delay combination treatment for the 6 weeks needed for study participation
• Patients with squamous cell non-small cell lung cancer are ineligible

PATIENT CHARACTERISTICS:

• ECOG performance status 0-2
• Absolute neutrophil count ≥ 2,000/mm³
• Platelet count ≥ 100,000/mm³
• Hemoglobin ≥ 9.0 g/dL
• AST/ALT ≤ 2.5 times upper limit of normal (ULN) (5 times ULN if known liver metastases are present)
• Creatinine clearance ≥ 50 mL/min
• No proteinuria at baseline
• Patients with ≥ 1+ proteinuria during screening should undergo a timed 12- or 24-hour urine collection, which must be an adequate collection and must demonstrate < 500 mg protein/24 hr to be eligible for the study
• Not pregnant or nursing
• No nursing for ≥ 4 months after completion of study treatment
• Negative pregnancy test
• Fertile patients must use effective contraception during and for ≥ 4 months after completion of study treatment
• No arterial thromboembolic events within the past 6 months, including any of the following:
• Transient ischemic attack
• Cerebrovascular accident
• Unstable angina
• Myocardial infarction
• Clinically significant peripheral vascular disease
• No venous thromboembolic event within the past 3 months
• No clinically significant cardiovascular disease
• No uncontrolled hypertension
• No New York Heart Association class II or greater congestive heart failure
• No serious cardiac arrhythmia requiring medication
• Atrial or supraventricular tachycardias that are well controlled with beta blockers or calcium channel blockers are allowed
• Chronic pacemakers allowed
• No presence of bleeding diathesis or coagulopathy
• No significant traumatic injury within the past 4 weeks
• No history of other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or that might affect the interpretation of the results of the study or render the patient at high risk from treatment complications

PRIOR CONCURRENT THERAPY:

• No administration of nitrates within the past week
• At least 2 weeks since prior and no concurrent antihypertensive agent(s)
• Must have stable blood pressure (BP) (BP < 160/100 mm Hg) within the past 2 weeks
• Must be asymptomatic within the past 2 weeks
• No open biopsy within the past 14 days
• No fine needle aspirations other than in the breast within the past 7 days
• No placement of a vascular access device within the past 7 days

• No radiotherapy within the past 4 weeks
• No previous treatment with bevacizumab
• No need for major surgical procedure during the course of the study
• No other cancer immunotherapy or biologic therapy while on the study
• No concurrent or recent (within past 10 days) use of full-dose oral or parenteral anticoagulants (heparin > 10,000/day or an INR > 1.5) or thrombolytic agents
• 1 mg of warfarin is permitted as required to maintain patency of preexisting, permanent indwelling IV catheters
• No chronic, daily treatment with aspirin (> 325 mg/day) or nonsteroidal anti-inflammatory medications (of the kind known to inhibit platelet function at doses used to treat chronic inflammatory diseases)
