Description:
This is an open-label, prospective, randomized, multicenter phase II trial that will evaluate
the efficacy and safety of intermittent addition of cetuximab to a FOLFIRI-based first line
therapy to patients with RAS (Rat sarcoma)-mutant mCRC (Metastatic colorectal cancer)
diagnosis who convert to RAS wild-type using monitoring of the RAS mutation status by liquid
biopsy.

Purpose
This is an open-label, prospective, randomized, multicenter phase II trial that will evaluate
the efficacy and safety of intermittent addition of cetuximab to a FOLFIRI-based first line
therapy to patients with RAS (Rat sarcoma)-mutant mCRC (Metastatic colorectal cancer)
diagnosis who convert to RAS wild-type using monitoring of the RAS mutation status by liquid
biopsy.
Trial Arms
Name | Type | Description | Interventions |
---|
FOLFIRI + cetuximab | Experimental | Patients in Arm A will receive FOLFIRI + cetuximab until progressive disease (PD), unacceptable toxicity, withdrawal of informed consent or death, whatever occurs first. The recurrence of RAS-mutation without PD to switch back to FOLFIRI. In case of repeated conversion to RAS wild-type without PD, treatment will shift to FOLFIRI + cetuximab again, and so on. Switches of treatment will proceed until progressive disease (PD), unacceptable toxicity, withdrawal of informed consent or death, whatever occurs first.
[FOLFIRI = Irinotecan, Folinic acid (racemic), Fluorouracil (5-FU)] | |
FOLFIRI | Other | Patients in Arm B will continue therapy with FOLFIRI until PD, unacceptable toxicity, withdrawal of informed consent or death, whatever occurs first. | |
