ABSTRACT: Background
Combination therapy with oral fluoropyrimidine and irinotecan has not yet been established as first-line treatment of metastatic colorectal cancer (mCRC). We carried out a randomized, open-label, phase III trial to determine whether S-1 and irinotecan plus bevacizumab is noninferior to mFOLFOX6 or CapeOX plus bevacizumab in terms of progression-free survival (PFS).Patients and methods
Patients from 53 institutions who had previously untreated mCRC were randomly assigned (1 : 1) to receive either mFOLFOX6 or CapeOX plus bevacizumab (control group) or S-1 and irinotecan plus bevacizumab (experimental group; a 3-week regimen: intravenous infusions of irinotecan 150?mg/m2 and bevacizumab 7.5?mg/kg on day 1, oral S-1 80?mg/m2 twice daily for 2?weeks, followed by a 1-week rest; or a 4-week regimen: irinotecan 100?mg/m2 and bevacizumab 5?mg/kg on days 1 and 15, S-1 80?mg/m2 twice daily for 2?weeks, followed by a 2-week rest). The primary end point was PFS. The noninferiority margin was 1.25; noninferiority would be established if the upper limit of the 95% confidence interval (CI) for the hazard ratio (HR) of the control group versus the experimental group was less than this margin.Result
Between June 2012 and September 2014, 487 patients underwent randomization. Two hundred and forty-three patients assigned to the control group and 241 assigned to the experimental group were included in the primary analysis. Median PFS was 10.8?months (95% CI 9.6-11.6) in the control group and 14.0?months (95% CI 12.4-15.5) in the experimental group (HR 0.84, 95% CI 0.70-1.02; P?ConclusionS-1 and irinotecan plus bevacizumab is noninferior to mFOLFOX6 or CapeOX plus bevacizumab with respect to PFS as first-line treatment of mCRC and could be a new standard treatment.Clinical trials number
