Brief Summary:
  • The association of FOLFOX (5-fluoruracil, folinic acid, and oxaliplatin) and pan is a standard option for the first-line treatment of unresectable RAS and BRAF wt mCRC patients.
  • The phase III TRIBE trial recently demonstrated that FOLFOXIRI (5-fluoruracil, folinic acid, oxaliplatin and irinotecan) plus bev significantly prolongs PFS and OS and increases RECIST response rate, ETS and DoR, as compared to FOLFIRI (5-fluoruracil folinic acid, and irinotecan) plus bev. The advantage provided by the intensification of the upfront chemotherapy backbone is independent of RAS and BRAF mutational status.
  • Some phase II trials recently assessed the safety and activity of the combination of three-drugs chemotherapy regimens with an anti-EGFR monoclonal antibody. Promising activity results in terms of RECIST response rate and R0 resection rate have been achieved, with some safety concerns with special regards to gastrointestinal toxicity.
  • In the phase II randomized MACBETH study the combination of a modified schedule of FOLFOXIRI with cetuximab determined remarkable activity results, with an acceptable and manageable safety profile.
  • The optimal duration of the upfront treatment with chemotherapy plus anti-EGFRs is not established. The phase II MACRO-2 trial suggested that interrupting FOLFOX after 4 months while continuing cet alone as maintenance, is a reasonable option.
  • Activity parameters (RECIST response rate, ETS, DoR) are clinically relevant endpoints, associated with longer survival, in particular with anti-EGFR moAb-based treatment.

On the basis of these considerations, we designed the present phase III randomized trial of first-line mFOLFOXIRI plus pan versus mFOLFOX6 plus pan in RAS and BRAF wt unresectable mCRC patients.

Drug Information available for: Panitumumab

Arm Intervention/treatment
Active Comparator: mFOLFOX6 + Panitumab
  • Panitumumab 6 mg/kg iv over 60 minutes, day 1 (if the first infusion is tolerated, then subsequent infusions may be administered over 30 to 60 minutes) followed by
  • Oxaliplatin 85 mg/sqm iv over 2 hours, day 1 in two-way with
  • L-Leucovorin 200 mg/sqm iv over 2 hours, day 1 followed by

  • 5-fluoruracil 2400 mg/sqm 48 h-continuous infusion, starting on day 1; to be repeated every 2 weeks for a maximum of 12 cycles.
