- •Patients on heparin treatment should have a baseline activated partial thromboplastin time (aPTT) between 1.5 - 2.5 times ULN or patients value before starting heparin treatment
- •Patients on low molecular weight heparins (LMWH) should receive daily dose of 1.5 - 2 mg/kg (of enoxaparin) or appropriate doses of the correspondent anticoagulant, according to package insert

- •Patients not receiving anticoagulant medication must have an INR ≤ 1.5 and aPTT ≤ 1.5 times ULN within 7 days prior to randomization
排除标准

- •History or evidence upon physical/neurological examination of CNS disease unrelated to cancer, unless adequately treated with standard medical therapy (e.g. uncontrolled seizures).
- •Major surgical procedure, open biopsy or significant traumatic injury within 28 days prior to randomization, or anticipation of the need for major surgery during the course of the study treatment.
- •Minor surgical procedures, including insertion of an indwelling catheter, within 24 hours prior to randomization.
- •Current or recent (within 10 days of first dose of bevacizumab) use of aspirin (> 325 mg/day) or clopidogrel (> 75 mg/day).
- •Chronic daily treatment with corticosteroids (dose of > 10 mg/day methylprednisolone equivalent) (excluding inhaled steroids).

- •Uncontrolled hypertension (systolic > 150 mmHg and/or diastolic > 100 mmHg).
- •Clinically significant (i.e. active) cardiovascular disease, requiring medication during the study and might interfere with regularity of the study treatment, or not controlled by medication.
- •Non-healing wound, active peptic ulcer or bone fracture.
- •History of abdominal fistula, or any grade 4 non-gastrointestinal fistula, gastrointestinal perforation or intra-abdominal abscess within 6 months of randomization.
- •Active infection requiring i.v. antibiotics at randomization.
- •Pregnant or lactating females. Serum pregnancy test to be assessed within 7 days prior to study treatment start, or within 14 days with a confirmatory urine pregnancy test within 7 days prior to study treatment start.
- •Women of childbearing potential (< 2 years after the last menstruation) not using effective, non-hormonal means of contraception (intrauterine contraceptive device, barrier method of contraception in conjunction with spermicidal jelly or surgically sterile) during the study and for a period of 6 months following the last administration of study drug.
- •Men who do not agree to use effective contraception during the study and for a period of 6 months following the last administration of study drug.
- •Current or recent (within 28 days of randomization) treatment with another investigational drug or participation in another investigational study
- •Clinically significant malabsorption syndrome or inability to take oral medication.
- •Psychiatric disability judged by the Investigator to be interfering with compliance for oral drug intake.
- •Requirement for concurrent use of the antiviral agent sorivudine or chemically related analogues, such as brivudine.
- •Evidence of any other disease, metabolic or psychological 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 may affect patient compliance with study routines, or places the patient at high risk from treatment related complications.
- •Known Dihydropyrimidine Dehydrogenase (DPD) deficiency or prior unanticipated severe reaction to fluoropyrimidine therapy (with or without documented DPD deficiency)
- •Known hypersensitivity to any of the study drugs (including 5-FU) or excipients. Hypersensitivity to Chinese hamster ovary cell products or other recombinant human or humanized antibodies. History of hypersensitivity reactions with drugs formulated in Cremophor® EL (polyoxyethylated castor oil), or previous therapy with bevacizumab.

结局指标
主要结局
Overall Survival (PP Population)
时间窗: Time from the date of randomization to the date of death or date last known to be alive, assessed up to approximately 6 years
Overall survival (OS) defined as time from randomization to date of death from any cause. Patients without recorded death were censored at the date the patient was last known to be alive. OS was analyzed at two looks, one interim look and the final analysis. Due to group sequential testing, the overall significance level alpha = 0.025 was spent on both looks according to Lan-DeMets spending method with O'Brien-Fleming-type boundaries. Alpha spent at Interim after 47% of information was 0.0010. Alpha spent at final analysis after 99% of information was 0.0250.
Overall Survival (ITT Population)
