Details and patient eligibility

About

To evaluate the objective response rate, disease control rate, progression-free survival, overall survival, surgical conversion rate and safety of irinotecan liposome combined with 5-FU/LV+ bevacizumab regimen in first-line treatment of advanced metastatic colorectal cancer patients.

Full description

This is a Phase II clinical study to evaluate the efficacy and safety of the combination regimen of irinotecan liposome injection in the first-line treatment of metastatic colorectal cancer. Patients will receive liposomal injections of irinotecan 70mg/m^2 d1, bevacizumab 5mg/kg d1, LV 400mg/m^2 d1, 5-FU 400mg/m^2, then 2400mg/m^2, continuous intravenous infusion for 46-48h, d1-2. 86 eligible patients will be enrolled.
