Exploiting Circulating Tumour DNA to Intensify the Postoperative Treatment Resected Colon Cancer Patients

Registration Number
NCT05062889
Lead Sponsor
Gruppo Oncologico del Nord-Ovest
Brief 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

Detailed 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.

Subjects who are positive for either hepatitis B surface antibody (HBsAB) or antibodies to the hepatitis B core antigen (HBcAB) should be screened using PCR measurement of hepatitis B DNA levels. Subjects with hepatitis B DNA levels by PCR that require nucleoside analogue therapy are not eligible for the trial. The latest local guidelines should be followed regarding the monitoring of hepatitis B DNA levels by PCR subjects on study treatment.

Disease Free Survival TD1 (DFS-TD1)60 months after the randomization of first patient in adjuvant treatment

time from enrollment of the target-driven part 1 of the study to the first documentation of disease relapse or death due to any cause, whichever occurs first. Secondary colorectal cancers are regarded as DFS events, whereas non-colorectal tumors are not. DFS will be censored on the date of the last evaluable on study tumor assessment documenting absence of relapse for patients who are alive, on study and disease free at the time of the analysis. Alive patients having no tumor assessments after enrollment will have time to event censored on the date of enrollment.
