N2 - Purpose: We aimed to determine the recommended dose for bi-weekly XELIRI plus bevacizumab for second-line chemotherapy and examined its safety and efficacy in patients with metastatic colorectal cancer resistant to oxaliplatin-based first-line chemotherapy. Methods: Irinotecan and bevacizumab were administered as a continuous intravenous infusion on Day 1 at 150 mg/mm2 and 5 mg/kg, respectively. Capecitabine was orally administered in two divided doses on Days 2–8. Each 2-week treatment cycle was defined as a single course of treatment. During Phase I, we determined the recommended dose for capecitabine. In Phase II trials, efficacy and treatment safety was verified (UMIN000003934). Results: The recommended dose of capecitabine was determined to be 2000 mg/m2. Median progression-free survival was 7.8 months [95% confidence interval (CI) 6.1–10.9 months], and median overall survival was 18.9 months (95% CI 11.6–28.4 months). Response rate was 17.4% (95% CI 6.4–28.3%). The most common Grade ≥3 hematotoxic adverse events were anemia (10.9%), neutropenia (10.9%), and leukopenia (8.7%), while the occurrence rate of Grade ≥3 non-hematotoxic adverse events was relatively low (<10%). Conclusion: Bi-weekly XELIRI plus bevacizumab was found to be a safe and effective second-line treatment in patients with metastatic colorectal cancer resistant to oxaliplatin-based first-line chemotherapy.
