Fruquintinib Plus FOLFIRI in RAS-mutated Metastatic Colorectal Cancer

Phase 2

Not yet recruiting

• Conditions: Colorectal Cancer
• Interventions: Drug: intensive treatment; Drug: Maintenance treatment

• Registration Number: NCT05842525
• Lead Sponsor: Hunan Cancer Hospital

Brief Summary

RAS mutations are found in nearly half of colorectal cancer patients. However, except for G12C mutation, no driven gene targeted drug can be used. the commonly first-line used treatment regimen is bevacizumab combined with chemotherapy. Angiogenesis is an important therapeutic target in colorectal carcinoma. Fruquintinib is an oral small molecule inhibitor of VEGFR1/2/3, has approved for the third-line treatment of refractory colorectal cancer.

Detailed Description

This is a prospective ,single-center, open labeled, single-arm phase II study exploring the efficacy and safety of fruquintinib combined with FOLFIRI as second-line treatment of RAS-mutated metastatic colorectal cancer (mCRC) in patients with disease progression during or after first-line therapy with bevacizumab, oxaliplatin, and a fluoropyrimidine.
