Brief Summary

Currently, the approved third-line treatments for metastatic colorectal cancer (mCRC) include regorafenib, fruquintinib, and trifluridine/tipiracil(TAS-102). In recent years, several phase I/II studies evaluated the combination of TAS-102 and bevacizumab in mCRC patients who were refractory to standard therapies and showed promising antitumor efficacy and manageable toxicity. In this single-center phase II study, the investigators explored the efficacy and safety of irinotecan, TAS-102, plus bevacizumab in a third-line or beyond therapy for patients with mCRC.

Detailed Description

The mCRC patients who are refractory to standard therapies and need a third-line or beyond therapy are eligible. Patients who previously received irinotecan while progressing during maintenance therapy are also eligible.

These patients received an intravenous infusion of irinotecan (150mg/m2 on day 1) plus bevacizumab (5 mg/kg on day 1) and an oral administration of TAS-102(30 mg/m2 given bid on days 1-5), repeated every 14 days.

The primary endpoint was the objective response rate (ORR), and the secondary endpoints included progression-free survival (PFS), overall survival (OS), and safety.
