Clinical Trial Summary

The phase I/II study was designed to evaluate if the regimen of Irinotecan, Oxaliplatin, Capecitabine (XELOXIRI) and Bevacizumab is a superior first-line option for patients with metastatic colorectal cancer(mCRC) in terms of safety and efficacy.

Description:

Recent studies have shown that the triplet-drug regimen FOLFOXIRI (irinotecan/oxaliplatin/fluorouracil) can further improves survival benefit for patients with metastatic colorectal cancer(mCRC) compared to standard two-drug regimens in first-line therapy, especially when combined with bevacizumab. However, the increased toxicities of FOLFOXIRI limited its usage. Capecitabine demonstrates a superior efficacy and safety than fluorouracil, so we designed this trial to evaluate if the XELOXIRI plus bevacizumab can be a better alternative to FOLFOXIRI plus bevacizumab. The phase I study is to determine the safety and the recommended phase II dose (RP2D) of XELOXIRI plus Bevacizumab. In the phase II study, we aim to determine the efficacy of the regimen as first-line therapy for mCRC and explore potential molecular biomarkers (genomes, circulating tumor cell) for toxicity forecasting or efficacy monitoring.
