Irinotecan Combined With S-1( IRIS ) Followed by mFOLFOX6 Regimen Versus mFOLFOX6 Followed by IRIS Regimen in Advanced Colorectal Cancer
Irinotecan Combined With S-1( IRIS ) Followed by mFOLFOX6 Regimen Versus mFOLFOX6 Followed by IRIS Regimen in Advanced Colorectal Cancer
This randomized phase III study compares safety and efficacy of two sequence arms in advanced colorectal cancer: irinotecan and S-1 (IRIS) followed by oxaliplatin containing regimen (arm A), or l-leucovorin (l-LV), 5-FU and oxaliplatin (mFOLFOX6) followed by irinotecan containing regimen (arm B).
A multicenter randomized open-label controlled phase III study is conducted in patients with inoperable advanced or metastatic colorectal cancer who receive no previous chemotherapy. Usefulness of IRIS and mFOLFOX6 regimens as the 1st-line therapy for colorectal cancer is evaluated in PFS, MST, incidence and severity of adverse events
