Study Details

This clinical program aims to evaluate the activity and efficacy of cetuximab continuation of treatment for three lines of therapy with rotation of chemotherapy (FOLFIRI, FOLFOX, irinotecan) in mCRC patients, whose tumors remain RAS/BRAF WT. The study will also evaluate the activity and efficacy of cetuximab re-introduction in combination with irinotecan as third line therapy in the concept of re-challenge for those patients that will be treated in second line with chemotherapy plus anti-angiogenic drugs (FOLFOX plus bevacizumab), having a RAS or BRAF mutant disease at the time of progression after FOLFIRI plus cetuximab first line treatment. A novel characteristic of this program is that the therapeutic algorithm will be defined at each treatment decision (first line, second line and third line) in a prospective fashion in each patient by liquid biopsy assessment of RAS/BRAF status.

Arms

  • Experimental: single arm
    This is an open-label phase II study investigating the efficacy and safety of a bio-marker-driven cetuximab-based treatment regimen over 3 treatment lines in mCRC patients with RAS/BRAF wt tumors at start of first line. Based on dynamic and longitudinal liquid biopsy assessment of RAS/BRAF status, that will be prospectively performed before each line of treatment, mCRC patients will be treated with cetuximab in combination with chemotherapy throughout three lines of therapy, as follows: * FOLFIRI plus cetuximab (first line); * FOLFOX plus cetuximab (second line); * irinotecan plus cetuximab (third line). If at progression after the first line or after the second line, the liquid biopsy assessment indicates RAS and or BRAF mutant status, patients will be treated with FOLFOX plus bevacizumab as second line of therapy, or with regorafenib or with trifluridine-tipiracil (investigator's choice) as third line therapy.
