Clinical Trial Summary

The aims of this study are to evaluate if an intensified adjuvant treatment with FOLFOXIRI could increase the rate of cases with undetectable ct-DNA after chemotherapy and to evaluate if a further adjuvant treatment with Trifluridine/Tipiracil could increase the rate of cases with undetectable ct-DNA and therefore improve DFS in a population at high-risk of relapse. An additional target-driven cohort of HER2+ RAS wild-type colon cancer patients will be assessed for ct-DNA clearance after a tailored treatment with Trastuzumab and Tucatinib plus FOLFOX


Clinical Trial Description

This is a prospective, open-label, multicentre study, including two phase II randomized trials. In Part 1 resected stage III and high-risk stage II colon cancer patients with positive ct- DNA after surgery will be randomized to receive FOLFOX for 12 cycles or CAPOX for 8 cycles (at investigator choice) versus FOLFOXIRI for 12 cycles. In Part 1 target-driven resected stage III and high-risk stage II HER2+ and RAS wild-type colon cancer patients with positive ct-DNA after surgery will receive Trastuzumab and Tucatinib plus FOLFOX for 12 cycles. In Part 2 resected stage III and high-risk stage II colon cancer patients with positive ct- DNA after the end of a fluoropyrimidine and oxaliplatin-based adjuvant therapy - either in the frame or outside of Part 1 - will be randomized to receive observation or Trifluridine/Tipiracil for 6 cycles. ;
