Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to compare the efficacy and safety of the combination of immune checkpoint inhibitors (ICIs) and FOLFOX regimen compared to FOLFOX regimen alone in the neoadjuvant chemotherapy of locally advanced colorectal cancer. The main question aims to answer are:

Question 1: Compare the pathological complete response rate between the combination of ICIs and FOLFOX regimen and the FOLFOX alone.

Question 2: Compare the survival outcomes and safety between the combination of ICIs and FOLFOX regimen and the FOLFOX alone.

Two groups of participants will receive different new adjuvant chemotherapy regimens, and their efficacy will be compared.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A prospective, randomized, open, multi-center clinical study evaluating the efficacy (pathological response, survival outcomes) and safety of the combination of ICIs and FOLFOX regimen compared to FOLFOX regimen in the treatment of locally advanced colorectal cancer.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

ICIs + FOLFOX group

Patients in this group will receive ICIs combined with FOLFOX regimen, specifically: ICIs, intravenous infusion, D1; Oxaliplatin (85mg/m2), intravenous infusion, D1; Calcium folinate (400mg/m2), intravenous infusion, D1; 5-FU (400mg/m2), intravenous infusion, D1, then continuous intravenous infusion of 1200mg/(m2·d)×2d (total amount of 2400mg/m2, infusion for 46-48h) every two weeks. Imaging evaluation will be performed after 3 cycles of preoperative treatment. If the disease is resectable, surgery will be performed. If R0 resection is achieved, the preoperative regimen will continue for up to 9 cycles.

FOLFOX group

Patients in this group will undergo FOLFOX chemotherapy regimen, specifically: Oxaliplatin 85 mg/m2 dissolved in 500 ml of 5% glucose solution, intravenous drip, on Day 1, in combination with calcium folinate (400mg/m2), intravenous infusion, on Day 1, and 5-FU (400mg/m2), intravenous infusion, on Day 1, followed by continuous intravenous infusion of 1200mg/(m2·d) for 2 days (total dose of 2400mg/m2, infusion for 46-48 hours), once every 2 weeks. After 3 cycles of preoperative treatment, imaging evaluation will be performed. If the disease is resectable, surgery will be performed. If R0 resection is achieved, the preoperative treatment regimen will be continued after surgery, for a maximum of 9 cycles.

* Voluntary participation in this study and signed informed consent form;
* Expected good compliance to complete the study treatment, follow-up for efficacy and adverse reactions according to the protocol requirements.

Exclusion Criteria

* Pathology is other malignant tumors besides adenocarcinoma, such as squamous cell carcinoma, gastrointestinal stromal tumor, melanoma, etc.;
* Within 5 years prior to the first use of investigational drug, diagnosed with other malignant tumors, excluding effectively treated basal cell carcinoma, squamous cell carcinoma of the skin, and/or in situ cervical cancer and/or breast cancer effectively removed;
