Study Overview
Brief Summary
This is a phase II randomized study of 4-months induction first-line chemotherapy with FOLFOXIRI + cetuximab followed by maintenance with cetuximab or bevacizumab in patients affected by KRAS wild type (wt) mCRC.
Detailed Description
The aim of the study is to obtain a rapid disease control with the therapy and the maximum tumoral shrinkage, and than to treat patient with less intensive maintenance to inhibit tumoral regrowth.

Outcomes
Primary Outcomes
10 months-progression free rate (10m-PFR)
Time Frame: up to 10 months
10m-PFR is defined as the proportion of patients free from disease progression 10 months after randomization, relative to the total of enrolled patients. Patients whose disease status cannot be evaluated within 11 months after randomization and patients lost to follow up or dead within 10 months after randomization will be considered as progressed for the purpose of the primary endpoint analyses.
Secondary Outcomes
- Best overall response rate(every 8 weeks, up to 60 months)
- 10 month resection rate(within 10 months after randomization)
- Time to strategy failure(from randomization, up to 60 months)
- Time to 2nd progressive disease(from randomization, up to 60 months)
- Progression free survival (PFS)(from randomization to first documentation of objective disease progression or death, up to 60 months)
- Overall survival (OS)(as the time from randomization to the date of death, up to 60 months)
- Toxicity rate(during the induction and the maintenance phases of treatment)
- Overall toxicity rate(during the induction and the maintenance phases of treatment)
