NCT07389265

Brief Summary

The goal of this Phase 3 clinical trial is to evaluate whether continuing cetuximab treatment beyond first-line progression can improve outcomes in patients with metastatic colorectal cancer whose tumors are RAS and BRAF wild-type. The study will compare the effectiveness of chemotherapy given together with cetuximab versus chemotherapy given together with bevacizumab. Researchers aim to determine whether cetuximab continuation improves tumor response, progression-free survival, overall survival, and safety in this patient population. Eligible participants are adults with metastatic colorectal cancer who have previously responded to first-line treatment with chemotherapy combined with an anti-EGFR antibody. Before starting therapy, patients will undergo molecular testing using liquid biopsy to confirm tumor characteristics. They will then receive chemotherapy with either cetuximab or bevacizumab every two weeks, and their disease will be monitored regularly with CT or MRI scans, laboratory tests, and clinical evaluations. During the study, patients will also provide biological samples for translational research. This trial will enroll about 360 patients across sites in Italy and Spain and is designed to provide new evidence on whether cetuximab continuation beyond first-line treatment can offer a meaningful clinical benefit compared with standard therapy.

Outcome Measures

Primary Outcomes (1)

  • Overall Response Rate (ORR)

    The primary outcome is the Objective Response Rate, which will be evaluated according to the RECIST criteria 1.1. The study aims to determine if the continuous use of cetuximab in the experimental arm results in a superior Response Rate compared to the control arm with bevacizumab.

    From date of randomization until the date of first documented progression or date of death from any cause, or study completion whichever came first, assessed until 48 months.

Secondary Outcomes (3)

  • Overall Survival (OS)

    From randomization (Day 0) until death from any cause, assessed through study completion (up to 36 months of survival follow-up)

  • Progression-Free Survival (PFS)

    From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 48 months from last patient randomized.

  • Safety Profile: Incidence of Adverse Events (AEs) and Serious Adverse Events (SAEs)

    From first treatment administration until 30 days after the last dose.

Study Arms (2)

ARM A Chemo-doublet (FOLFIRI or FOLFOX) + Cetuximab

EXPERIMENTAL

This arm is for participants with RAS/BRAF wild-type metastatic colorectal cancer who have progressed after first-line anti-EGFR therapy. They will receive a second-line chemotherapy regimen (either FOLFIRI or FOLFOX) in combination with cetuximab. The objective is to evaluate the efficacy of continuing cetuximab beyond progression.

Drug: Erbitux (Cetuximab)Drug: FOLFOX (Folinic acid + Fluorouracil + Oxaliplatin)Drug: FOLFIRI (5-Fluorouracil, Folinic acid, Irinotecan)

ARM B Chemo-doublet (FOLFIRI or FOLFOX) + Bevacizumab

ACTIVE COMPARATOR

This arm is for participants with RAS/BRAF wild-type metastatic colorectal cancer who have progressed after first-line anti-EGFR therapy. They will receive a second-line chemotherapy regimen (either FOLFIRI or FOLFOX) in combination with bevacizumab. This arm serves as the control group to compare the outcomes with the experimental arm.

Drug: BevacizumabDrug: FOLFOX (Folinic acid + Fluorouracil + Oxaliplatin)Drug: FOLFIRI (5-Fluorouracil, Folinic acid, Irinotecan)

Interventions

This is an anti-EGFR monoclonal antibody administered in combination with chemotherapy. The dose is 500 mg/m² administered every 14 days as a 120-minute intravenous infusion on cycle 1 day 1, infusion rate not faster than 5mg/min.

ARM A Chemo-doublet (FOLFIRI or FOLFOX) + Cetuximab

This is an anti-VEGF monoclonal antibody used as an active comparator in the control arm of the study. The dose is 5 mg/kg of body weight, administered every 14 days

ARM B Chemo-doublet (FOLFIRI or FOLFOX) + Bevacizumab

This is a standard chemotherapy regimen containing irinotecan, fluorouracil, and folinic acid. It is used as the backbone chemotherapy in both study arms. The dose includes 200 mg/m2 L-folinic acid given concurrently with 85 mg/ m² oxaliplatin over 2 h IV, followed by a 400 mg/ m² IV bolus of fluorouracil followed by 2400 mg/ m² fluorouracil IV infusion every 14 days.

ARM A Chemo-doublet (FOLFIRI or FOLFOX) + CetuximabARM B Chemo-doublet (FOLFIRI or FOLFOX) + Bevacizumab

This is a standard chemotherapy regimen containing folinic acid, oxaliplatin, and fluorouracil. It is used as the backbone chemotherapy in both study arms. The dose includes 200 mg/m2 L-folinic acid given concurrently with 180 mg/ m² irinotecan over 1.30 h IV infusion, followed by a 400 mg/ m² IV bolus of fluorouracil followed by 2400 mg/ m² fluorouracil IV infusion over 46 h every 14 days.
