Design outcomes

Primary

MeasureTime frame
Main Objective: To assess whether the progression-free survival time under 5-FU/FA plus irinotecan plus cetuximab is longer than that under 5-FU/FA plus irinotecan as first-line treatment for epidermal growth factor receptor-expressing metastatic colorectal cancer.;Secondary Objective: To compare between the 2 treatment groups for: Overall survival time Response rate (modified WHO criteria) Disease control rate To determine: Duration of response Quality of life (EORTC QLQ-C30 Questionnaire) Safety.;Primary end point(s): Progression free survival
