Exclusion Criteria

- Any unresolved toxicity >CTC grade 2 from previous treatments.
- Prior therapy with FOLFOX or other oxaliplatin containing regimens including adjuvant therapy <12 months before entry into the study.
- Prior therapy with a VEGF inhibitor.
- Untreated unstable brain or meningeal metastases. Patients with radiological evidence of stable brain metastases are eligible providing that they are asymptomatic and either do not require corticosteroids or have been treated with corticosteroids, with clinical and radiological evidence of stabilisation at least 10 days after discontinuation of steroids.
- Inadequate bone marrow reserve as demonstrated by an absolute neutrophil count £1.5 x 109/L or platelet count £100 x 109/L or requiring regular blood transfusions to maintain haemoglobin >9 g/dl.
- Serum bilirubin ³1.5 x upper limit of reference range (ULRR).
- Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ³2.5 x ULRR. If liver metastases are present, ALT or AST >5 x ULRR.
- Serum creatinine >1.5 x ULRR or a creatinine clearance of £50 mL/min calculated by Cockroft-Gault formula (see Section 4.7.2.2).
- Greater than +1 proteinuria on 2 consecutive dipsticks taken no less than 1 week apart or if urinary protein =1.5 g in a 24 hour urine collection.
- Patients with a history of poorly controlled hypertension with resting BP >150/100 mmHg in the presence or absence of a stable regimen of anti hypertensive therapy. Measurements will be made after the patient has been resting supine for a minimum of 5 minutes. Two or more readings should be taken at 2 minute intervals and averaged. If the first 2 diastolic readings differ by more than 5 mmHg then an additional reading should be obtained, and averaged.
- Any evidence of severe or uncontrolled systemic diseases (eg, unstable or uncompensated respiratory disease, cardiac disease including arrhythmias, hepatic or renal disease).
- Mean QTc with Bazett’s correction >470 msec in screening electrocardiogram (ECG) or history of familial long QT syndrome (as per ICH guideline E14).
- Recent (<14 days) major surgery prior to entry into the study, or a surgical incision that is not fully healed.
- Significant haemorrhage (>30 mL/episode in previous 3 months) or haemoptysis (>5 mL fresh blood in previous 4 weeks).
- Pregnant or breast-feeding women or women of childbearing potential with a positive pregnancy test prior to receiving study medication.
- Known severe hypersensitivity to AZD2171, bevacizumab, oxaliplatin, 5 FU or leucovorin, or any of the excipients of these products.
- Other concomitant anti-cancer therapy.
- History of other malignancies within 5 years except for adequately treated basal or squamous cell skin cancer or carcinoma in situ.
- History of central nervous disorders or uncontrolled seizures.
- History of significant gastrointestinal impairment, as judged by the investigator that would significantly affect the absorption of AZD2171.
- Peripheral neuropathy.
- Known dihydropyrimidine dehydrogenase deficiency.
- Hypersensitivity to Chinese hamster ovary cell products or other recombinant or humanised antibodies.
- Previous enrolment or randomisation of treatment in the present study.
- Participation in a clinical study during the last 30 days.
- Known infection with hepatitis B or C or HIV
