Background
The aim of this study is to demonstrate that capecitabine metronomic chemotherapy is non-inferior to capecitabine conventional chemotherapy as maintenance treatment, in patients who have responded to 16–18 weeks first-line chemotherapy in metastatic colorectal cancer (mCRC).
Methods
The study design is a prospective, randomized, open label, phase II clinical trial. Those patients with mCRC who respond well after 16–18 weeks of standard doublet chemotherapy as induction may be enrolled into this study, and randomly assigned to the capecitabine metronomic group or standard dosage group. The duration of disease control after randomization and progression-free survival after enrollment are the primary endpoints. Overall survival, safety, and quality of life are the secondary endpoints. The sample size required to achieve the research objectives of this project is 79 patients in each group. The study recently started on 1 January 2018, and will last for 36 months.
Discussion
This project is intended to study the efficacy and safety of capecitabine metronomic chemotherapy in the maintenance treatment of advanced colorectal cancer, and to explore the strategy of “low toxicity, high efficiency, economy, and individualization”, which is suitable for China’s national conditions and pharmacoeconomics. It has great prospects for clinical application and a clear socioeconomic value.
