Metastatic Colorectal Cancer
Conditions
Brief summary
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.
Detailed 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.
Interventions
70 mg/m\^2 , d1, 14 days per cycle, 8 cycles.
5-FU 400mg/m\^2, then 2400mg/m\^2, continuous intravenous infusion for 46-48h, d1-2, 14 days per cycle, 8 cycles.
400mg/m\^2, d1, 14 days per cycle, 8 cycles.
5mg/kg, d1, 14 days per cycle, 8 cycles.
