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.


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


  • 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)
