Known hypersensitivity or contraindication to the drugs used in the trial (eg: aflibercept, 5-FU, folinic acid/ leucovorin, oxaliplatin, bevacizumab, irinotecan). 20. Concomitant treatment with ASS > 325 mg or NSAIDs, known to inhibit platelet function, sorivudin or analog compounds or preparations of St. John’s wort. 21. Inability or unwillingness to comply with the protocol.
