About this study
Official title: Study of Vascular Endothelial Growth Factor A Targeting NIR-II Fluorescence in the Endoscopy of Gastrointestinal Tract
In this study, the investigators are studying new ways to look for abnormal tissues of the gastrointestinal tract during an endoscopy. We are using a VEGF-A targeting fluorescent probe and a NIR-II fluorescent endoscope to help detect abnormal tissues that are hard to see by the naked eye.
The main purposes of this study include:
- To translate the NIR-II approach into the endoscopy, and understand its advantages and limitations on detecting abnormal tissues in gastrointestinal.
- To validate whether topical administration of a targeting probe can stick to abnormal tissues and be detected by the NIR-II endoscope.
- To validate the safety and effectiveness of the topical administration of VEGF-A targeting probes for clinical application.
- Being tested
- Bev-ICG, NIR-II fluorescence endoscopy platform
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Bev-ICGDrug
Probe targeting VEGF-A that is topically administrated during the endoscopy
NIR-II fluorescence endoscopy platformDevice
An endoscopic detection device which can detect and visualize NIR-II fluorescent signal during the endoscopy
| Study group | Role | What they receive |
|---|---|---|
| Bev-ICG NIR-II Endoscopy | Experimental | The patients will receive a topical administration of probe (Bev-ICG) during the endoscopy. Then fluorescence imaging will be performed to guide the detection. Receives: Drug: Bev-ICG; Device: NIR-II fluorescence endoscopy platform |
What is being measured
The primary outcome is the main question the study is designed to answer.
Validation of NIR-II endoscope and probe targeting VEGF-A
Demonstrate the feasibility of using the NIR-II endoscope and VEGF-A targeting fluorescent probe to image abnormal tissues of the gastrointestinal tract.
Measured: During endoscopy

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Bev-ICG and NIR-II fluorescence endoscopy platform in people with Gastrointestinal Carcinoma and Dysplasia, run by Institute of Automation, Chinese Academy of Sciences 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 5 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: looking for participants now, as of the sponsor's last update on 13 May 2025. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Lidan Fu (17754927702, fulidan2021@ia.ac.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Validation of NIR-II endoscope and probe targeting VEGF-A (time frame: During endoscopy). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 May 2025; AzTrials last refreshed its copy on 6 Nov 2026.
