Sponsor's own description

Colorectal cancer (CRC) is one of the most common malignant tumors. With the rapid development of China's economy, people's living standards have been significantly improved, and lifestyles and dietary structures have changed. Smoking, drinking, high-fat, high-energy diets, etc. have led to an increase in the incidence of colorectal cancer year by year. Data show that in 2022, there will be 510,000 new cases of colorectal cancer in China, and about 240,000 deaths related to colorectal cancer. Radical surgery is the main initial treatment for early and middle-stage colorectal cancer and some metastatic colorectal cancer. Although the level of surgical treatment of colorectal cancer has been greatly improved and can achieve cure for some patients, its 5-year overall survival rate is only about 60%, and the main cause of death is distant metastasis and recurrence. In recent years, with the in-depth understanding of the treatment mechanism of metastatic colorectal cancer (mCRC), a variety of new treatment options have been proposed and applied in clinical practice in order to improve the quality of life of patients and prolong their survival. Trifluridine/tipivirine (TAS-102) is a new type of cytotoxic drug that exerts anti-tumor effects by directly incorporating into DNA chains to destroy DNA function. Its mechanism of action is different from that of fluorouracil drugs, and it can resist 5-fluorouracil (5-FU) resistance, providing a new treatment option for mCRC patients. TAS-102 has been approved in China for mCRC patients who have previously received fluoropyrimidine, oxaliplatin, and irinotecan-based chemotherapy, as well as those who have previously received or are not suitable for anti-vascular endothelial growth factor (VEGF) therapy and anti-epidermal growth factor receptor (EGFR) therapy (RAS wild type). Bevacizumab, as a monoclonal antibody targeting VEGF, exerts its anti-tumor effect by inhibiting tumor angiogenesis. Putlimumab, as an immune checkpoint inhibitor, enhances the body's immune response to tumors by blocking the PD-1/PD-L1 signaling pathway. Combination therapy has attracted much attention due to its possible synergistic effect. Studies have shown that TAS-102 combined with bevacizumab can achieve longer overall survival (OS) than TAS-102 monotherapy. In addition, TAS-102 combined with bevacizumab for refractory mCRC has also been approved by the FDA, showing its potential and importance in the treatment of mCRC. Therefore, this study aims to explore the efficacy and safety of TAS-102 combined with bevacizumab and putelimab in patients with mCRC after cytoreductive surgery, in order to provide a more effective treatment for mCRC patients. Through the design of a single-arm, single-center clinical study, we can have a deeper understanding of the efficacy and safety of this combined treatment in a specific patient population, providing a scientific basis for future clinical applications.
