Bevacizumab Plus mFOLFOXIRI as First-line Treatment for Patients With Unresectable Metastatic Colorectal Cancer

Summary

The current clinical trials and data on the triplet regimen combined with bevacizumab for first-line treatment of metastatic colorectal cancer were from European and American populations. The triplet regimens recommended by the NCCN and ESMO guidelines using irinotecan and 5-FU at a higher dose intensity cause a high incidence of adverse events in Asian population, and there was no high-quality data on efficacy in Chinese population, both of which have limited the clinical applications of the regimens in China. This study intends to conduct an improved triplet regimen (mFOLFOXIRI) combined with bevacizumab versus mFOLFOX6 combined with bevacizumab as a first-line multicenter, randomized, controlled phase III clinical trial in patients with advanced colorectal cancer. Progression-free survival (PFS), observable response rate (ORR), overall survival (OS), disease control rate (DCR), surgical resection rate, and safety and health-related quality of life (HRQoL) were assessed in the two groups of subjects.
