About this study
Official title: Cetuximab - IRDye800 Intraoperative Fluorescence Imaging in Esophagectomy of Esophageal Cancer:A Single Center Clinical Research
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.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Cetuximab-IRDye800 in people with Drug Safety ; Drug Specificity, run by Fifth Affiliated Hospital, Sun Yat-Sen University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 13 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Hong Shan, PhD (+86-18826913336, shanhong@mail.sysu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Tumor to Background Ratio (time frame: intra-operative). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04161560, which also lists 9 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
