Korábbi kezelés

• Patient previously treated for their metastatic cancer
• Patient previously treated with oxaliplatin
• Known allergy or hypersensitivity to antibodies or any preservatives if patient is treated with a monoclonal antibody combined to chemotherapy (bevacizumab or cetuximab or panitumumab or nivolumab or Trastuzumab For patients treated with trastuzumab : patient without HER2 overexpression (defined by positive IHC3 or positive IHC2 and confirmed by a positive FISH result)
• Patient with clinically significant coronaries affection or myocardial infarction within 6 months prior to randomization.
• Patient with an history of abdominal fistulas, trachea-esophageal fistulas or any other grade 4, gastro-intestinal perforations or non-gastrointestinal fistulas or intra-abdominal abscesses during the 6 months before randomization.
• For patient treated with bevacizumab: patient with uncontrolled arterial hypertension (systolic pressure >150 mmHg and/or diastolic pressure >100 mmHg) with and without antihypertensive medication. Patients with high hypertension are eligible if antihypertensive medication lowers their arterial pressure to the level specified by the criterion.
• Existence of any other pathology, metabolic problem, anomaly during the clinical examination or biological anomaly which may reasonable suspect an underlying pathology which would contra- indicate the use of the study medication or any other risk of complication related to the treatment.
• Any treatment including an experimental drug, or participation in another clinical trial within 28 days before randomization.
