Summary

This is a phase II, single-center, prospective trial aimed to investigate the efficacy and safety of a modified regimen of trifluridine/tipiracil plus bevacizumab in refractory metastatic colorectal cancer. Patients will be treated with trifluridine/tipiracil (17.5 mg/m2 dose orally twice daily, d1-10, every 14-days) plus bevacizumab (5mg/kg dose intravenously once at day 1, every 14-days). The study treatment will be administered until progression of disease, intolerable toxicity or withdraw of consent.

Detailed description

The treatment options as third-line therapy for metastatic colorectal cancer patients are limited. Trifluridine/tipiracil (TAS-102) plus bevacizumab has been approved in colorectal cancer for patients who are refractory to or intolerant of standard chemotherapy. However, the toxicity of trifluridine/tipiracil at standard dose a clinical concerned issue. Modifications of dose and treatment cycle of trifluridine/tipiracil have been investigated, and show promising effect to reduce the toxicity. In this study, patients with refractory metastatic colorectal cancer who have disease progression after at least 2 standard regimens will be treated with low-dose trifluridine/tipiracil plus bevacizumab. Trifluridine/tipiracil will be given at a 17.5 mg/m2 dose orally twice daily in a 14-day cycle consisting of 10 treatment days/4 rest days. Bevacizumab will be given at a 5mg/kg dose intravenously once at day 1 in a 14-day cycle. This regimen will be administered until progression of disease, intolerable toxicity or withdraw of consent.
