Summary

This study is a single-center, prospective, randomized, single-arm phase II clinical trial designed to evaluate the safety and efficacy of FULIRI chemotherapy regimen combined with targeted therapy (bevacizumab/cetuximab) as first-line conversion therapy for colorectal cancer with liver metastases. Eligible patients with colorectal cancer and liver metastases, after signing informed consent, received FULIRI chemotherapy combined with bevacizumab/cetuximab targeted therapy. Efficacy was assessed after every four treatment cycles, followed by multidisciplinary team (MDT) discussion regarding potential surgical resection, ablation, or stereotactic radiotherapy. The primary endpoint was the objective response rate (ORR), and secondary endpoints included: disease control rate (DCR), R0 resection rate of liver metastases, progression-free survival (PFS), 3-year/5-year survival rates, and the incidence of acute toxicities of any grade and grades 3/4.

Detailed description

Irinotecan (IRI, also known as CPT-11) is an important component in chemotherapy for metastatic colorectal cancer. It induces single-strand DNA damage and blocks DNA replication. After traditional irinotecan administration, both the parent drug and its active metabolite SN-38 exist in two forms: active lactone and carboxylate. The lactone ring structure is unstable in neutral and alkaline solutions. Under physiological pH conditions, the active lactone rapidly hydrolyzes and becomes inactive as a carboxylate, thus reducing its efficacy, which limits its clinical application. The most significant adverse events in patients receiving irinotecan treatment are diarrhea, nausea, vomiting, and neutropenia; in patients receiving irinotecan monotherapy, the main causes of treatment-related death are neutropenic infection, grade 4 diarrhea, and fatigue. Shijiazhuang Pharmaceutical Group's first generic irinotecan liposome is a new formulation that improves upon traditional irinotecan. It encapsulates the active substance irinotecan in liposomes, utilizing the enhanced permeability and retention (EPR) effect to specifically target the tumor area. This increases the affinity of the drug to cancer cells, overcomes drug resistance, reduces the dosage, improves efficacy, and reduces toxic side effects, thereby mitigating the limitations of irinotecan in clinical use. Currently, there is a lack of research data on irinotecan liposome combined with 5-FU/LV and targeted therapy in patients with advanced metastatic colorectal cancer. Because irinotecan liposome cannot directly replace the dosage of conventional irinotecan, we are conducting a phase II clinical study for first-line conversion therapy in patients with colorectal cancer liver metastases. This study aims to explore the safety and efficacy of irinotecan liposome combined with 5-FU/LV + bevacizumab or cetuximab, thus providing more treatment options for patients with advanced metastatic colorectal cancer.
