What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 3 trials are large pivotal studies comparing the treatment to current standard of care or placebo. Your participation directly contributes to the evidence needed for regulatory approval.

This trial targets 348 participants in total. It began in 2016-12 with a primary completion date of 2028-09.

Brief Summary

Colorectal cancer is the 3rd most common cancer in France and the 2nd cause of death from cancer. Between 30 to 60% of patients develop limited or predominant liver metastases. Surgical resection of these metastases, only curative treatment is not immediately possible in 10-15% of cases. In unresectable patients, current palliative treatments are based on systemic chemotherapy associated or not with the targeted therapies (anti-EGFR (panitumumab), anti-VEGF (bevacizumab)). In this patient population, special attention was paid to intensified treatment regimens in order to improve their efficiency and improving the tumoral response rate, the intensity of the response and its earliness correlate with improved overall and progression-free survival. The intra-arterial use of oxaliplatin coupled with IV chemotherapy has yielded OR levels of 64% in patients having survived one or more lines of chemotherapy IV and 62% in patients who have progressed on oxaliplatin IV. In addition, the HIA administration of oxaliplatin limits systemic and especially neurological toxicities, thanks to a greater hepatic clearance. In conclusion, the combination of systemic chemotherapy, targeted therapy and HIAC with oxaliplatin has showed promising efficacy results associated with good tolerance from the first line onwards. Indeed, we can expect from the Phase II recent data, a control rate close to 100%, with high response rates associated with early maturity and depth responses as well as prolonged survival. However, to date, in the absence of randomized trial testing this combination, this strategy does not have sufficient evidence to be integrated in our routine practices, and HIAC remains limited to a few expert centers in treatment catch-up.
