E.1.2 | Version | 16.0 |
E.1.2 | Level | PT |
E.1.2 | Classification code | 10052358 |
E.1.2 | Term | Colorectal cancer metastatic |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To provide an estimate (+/- 15%) of the progression-free survival (PFS) rate at 9 months, in patients without skin toxicity at 3 weeks (according to NCI CTCAE v. 4.0), treated with FOLFIRI + escalating dose of cetuximab (arm A). It is expected that the PFS rate will be similar to that observed after standard cetuximab treatment + FOLFIRI in patients with grade 1-4 skin toxicity in a K-Ras wild type population (CRYSTAL study). |
|
E.2.2 | Secondary objectives of the trial |
To evaluate PFS, overall survival (OS), overall response and response rate in liver-limited disease, disease control rate, duration of response, general resection rate and R0 resection rate for metastatic lesions, skin toxicity, general safety, biomarkers, proteomics, expression profiling, mutations in each of the treatment arms.
To evaluate pharmacokinetic parameters in patients in both treatment arms in selected centers.

11. Known allergy or any other adverse reaction to any of the drugs or to any related compound.
12. Known dihydropyrimidine dehydrogenase (DPD) deficiency.
13. Gilbert disease.
14. Previous (within 5 years) or concurrent malignancies at other sites with the exception of surgically cured or adequately treated carcinoma in-situ of the cervix and basal cell carcinoma of the skin.
15. Organ allografts requiring immunosuppressive therapy.
16. Pregnancy (absence confirmed by serum/urine beta human choriongonadotrophin in pre-menopausal women) or breast-feeding.
17. Medical, social or psychological condition which, in the opinion of the investigator, would not permit the patient to complete the study or sign meaningful informed consent.
