Summary

The esophageal squamous cell carcinoma (ESCC) has high prevalence and mortality in China, which become a severe challenge for public health. The molecular imaging technology has been developed for intra-operative visualization and precise resection of the tumors. The imaging probe possess high affinity to the tumor specific targets. Among the tumor related proteins, EGFR is located on the cell membrane and over expresses in more than 50% ESCC which has been used as an ideal target for molecular imaging.

Cetuximab is an EGFR targeting antibody for anti cancer therapy. When labeled with an commercial available fluorescence dye IRDye800, cetuximab has been used as molecular imaging probe in clinical trials for surgical navigation of cancers including head and neck squamous cell cancers and gliomas. Previous studies shown high safety when using this probe and excellence sensitivity for cancer detection, which bring great promise in translational medicine.

This is a single-center prospective sequential trial. It is the first attempt to apply cetuximab-IRDye800 probe in ESCC surgery. This probe will be produced under clinical Good Manufacturing Practice (cGMP) conditions. The ESCC patients will be recruited with strict criteria.Patients population is planned to be 40 cases between18 and 65 years old, without gender limit. The patients will be divided into four groups : control group without probe administration, 1% dose group (1% of therapeutic cetuximab dose; 2.5 Mg/m2) and 10% dose groups (10%of therapeutic cetuximab dose ;25mg/m2) and 25% dose group (25%of therapeutic cetuximab dose; 62.5mg/m2), 10 cases are sequential assigned to each group. After informed consent, patients will receive a systemic infusion of the study drug 2 days before surgery.

Primary (safety and efficiency) and secondary endpoints (tissue EGFR expression) will be recorded. Preoperative management and surgical procedures will been performed according to conventional protocols. Intra-operative imaging of the surgical field will be performed in real time at 2 time points: before and post tumor resection. The postoperative specimens will be subjected to pathological analysis including correlation study of fluorescence signal and tumor tissue in pathology slice.

A protocol for managing any allergic reaction related to systemic infusion of cetuximab has been established. The patient's vital signs and ECG will be closely monitored post probe administration. The blood, liver and kidney, coagulation function and cardiotoxicity will be evaluated before and post surgery.

This clinical trial is anticipated to validate the concept that intra-operative fluorescent imaging of esophageal squamous cell carcinoma with cetuximab-IRDye800 can facilitate the demarcation of tumor boundary and identification of metastatic lymph nodes and testify its safety.
