About this study

Official title: A Pilot Study of Indocyanine Green Fluorescent Molecular Imaging of the Gastrointestinal Tract

Standard white light endoscopy involves the passage of a thin, flexible camera into the colon from the anus. Although standard white light endoscopy can detect most polyps and precancerous areas in the gastrointestinal tract and colon, many studies have shown that even the most experienced doctors, under optimal conditions, can miss up to 15-25% of precancerous areas. Thus, there remains a clear need to develop new methods of improving standard white light endoscopy. We are investigating whether indocyanine green (ICG) can serve to highlight areas which are precancerous when the colon is visualized with a special cameral which shines fluorescent light. Information from other studies suggests that this ICG agent may help to visualize blood vessels flowing to precancerous areas in the colon. We are looking at the ability of ICG, in combination with an endoscope which shines fluorescent light, to visualize precancerous areas in the colon.

Read the detailed description
  • Participants will be scheduled for their regular lower endoscopy. On the day of the procedure, participants will come to the endoscopy unit at Massachusetts General Hospital. After arriving, participants will receive an intravenous line and meet with the research doctor to go over the procedure. The participant will then be transferred to the endoscopy procedure room and be administered sedatives until they are comfortable to proceed with the procedure.
  • The research doctor will pass the flexible study sigmoidoscope into the lower part of the rectum. At this time, a dose of the ICG contrast agent will be administered through the intravenous line. Any areas that are suspicious will be photographed using the camera in the scope. We will also biopsy/remove any suspicious areas and send it to the pathologist as we normally do during endoscopy.
  • Over the course of the study procedure, small doses of ICG will be administered to help find any precancerous areas. Altogether, the study exam should not take more than 10 to 15 minutes.

Questions about this trial

What is this clinical trial studying?

A study testing indocyanine green in people with High Risk Polyposis Syndrome and Distal Colonic Lesions, run by Massachusetts General Hospital at 2 sites in United States.

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 8 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: finished, as of the sponsor's last update on 24 Feb 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Feb 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Neoplastic Lesions Detected (time frame: upto 15 mins). 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 24 Feb 2014.
