Brief Summary

National trial, multicenter, randomized, phase II assessing FOLFIRINOX + Panitumumab versus mFOLFOX6 + Panitumumab in metastatic colorectal cancer patients selected by RAS and B-RAF status from circulating DNA analysis.

Evaluation of complete response rate on treatment combining FOLFIRINOX and panitumumab.

Detailed Description

PRIMARY OBJECTIVE: Evaluation of complete response rate on treatment combining FOLFIRINOX and panitumumab

SECONDARY OBJECTIVE(S):

* Overall Survival

* Progression free survival

* Secondary resection

* Early tumor shrinkage (ETS)

* Depth of response (DpR)

* Safety profile (NCI-CTCAE v4.03 classification)

* Diagnostic performance of ccfDNA analysis compared to the tumor-tissue analysis (current gold standard)
