Study Details

Study Description

Brief Summary

The aim of this study is to compare the activity and safety of Oxaliplatin and S-1 (OS) and Oxaliplatin and Capecitabine (XELOX) in patients with advance or recurrent colorectal cancer.

Condition or Disease	Intervention/Treatment	Phase
Colorectal Neoplasm	Drug: OS (oxalipaltin+S-1) Drug: XELOX (oxalipaltin+capecitabine)	Phase 2

Detailed Description

Oxaliplatin and oral fluoropyrimidines (capecitabine or S-1) are active agents for colorectal cancer. Recent a phase II trial of combination chemotherapy of oxaliplatin with S-1 (OS) and several phase II trial of combination chemotherapy of oxaliplatin with capecitabine (XELOX) demonstrated good activity and mild toxicity in advanced colorectal cancer. Oxaliplatin and S-1 or capecitabine have distinct mechanisms of action and no overlap of key toxicities. Furthermore, oxaliplatin and fluorouracil were shown to be highly synergistic, not only in preclinical models but also in subsequent clinical trials.
