Fruquintinib vs Bevacizumab Combined With Irinotecan Liposome and Capecitabine as Second-Line Therapy for Advanced Metastatic Colorectal Cancer

Summary

This study is divided into two phases. The first phase aims to preliminarily evaluate the efficacy and safety of fruquintinib in combination with irinotecan liposome and capecitabine as second-line therapy for advanced metastatic colorectal cancer. The second phase is designed to further assess the efficacy and safety of fruquintinib in combination with irinotecan liposome and capecitabine compared to bevacizumab in combination with chemotherapy, also as second-line treatment for advanced metastatic colorectal cancer. The first phase is a single-arm study, while the second phase is a randomized (1:1) controlled trial. Entry into the second phase is determined by the investigators based on the efficacy results from the first phase study: if the primary endpoint of progression-free survival (PFS) is met in the first phase, participants will proceed to the second phase study. In the second phase, randomization is stratified according to the RAS status and the presence of disease progression within six months of adjuvant or neoadjuvant therapy. In the second phase, patients will be ramdomly assigned to receive fruquintinib(4mg/d, PO, D1-14, Q3W) in combination with irinotecan liposome(56mg/m2, ivgtt, D1, Q3W) and capecitabine(800mg/m2, PO, BID, D1-14, Q3W) or bevacizumab(7.5mg/kg, ivgtt, D1, Q3W) in combination with the same chemotherapy. Every three weeks is a cycle.
