Design outcomes

Primary

MeasureTime frame
Main Objective: - To confirm the efficacy of bevacizumab in combination with oxaliplatin and capecitabine (XELOX) based regimen, based on progression free survival;Secondary Objective: - To evaluate the safety profile of bevacizumab in combination with oxaliplatin and capecitabine (XELOX) based regimen. - To determine the overall response rate, time to response, duration of response, overall survival rate, percentage of R0 resectability of metastatic lesions and quality of life of patients treated with bevacizumab in combination with oxaliplatin and capecitabine (XELOX);Primary end point(s): Progression free survival (PFS), defined as the time period from the start of study medication to disease progression or death from any cause.
