Barrett's EsophagusPhase 1NTR 1BNCT01630798
A In-Vivo Esophageal Protocol for Detection of Neoplasia in the Digestive Tract
A Phase 1 study testing GI heptapeptide in people with Barrett's Esophagus, run by University of Michigan at 1 site in United States.
Trial summary
You are invited to participate in a research study to develop new ways to look for abnormal areas/tissues of the esophagus. The current endoscopes used to look at the esophagus are very good, but if the area doesn't look different to the naked eye, then the endoscope can't improve on that. Read more about this study

About this study
Official title: A Phase 1B In-Vivo Esophageal Protocol for Detection of Neoplasia in the Digestive Tract
You are invited to participate in a research study to develop new ways to look for abnormal areas/tissues of the esophagus. The current endoscopes used to look at the esophagus are very good, but if the area doesn't look different to the naked eye, then the endoscope can't improve on that. The investigators are looking at using special fluorescent stains in addition to special endoscopes designed to see abnormal areas that are not obvious to the naked eye. Currently specialized microscopes and fluorescent stains are used in clinical laboratories but it takes several days of processing to get results. It may be very helpful to look for areas to sample for abnormal tissue during the endoscopy procedure.
You are being asked to let us use "fluorescent peptides" with a special endoscope that allow us to "see" your esophagus with both fluorescent and white light during your upper GI endoscopy procedure to help target your biopsies. Peptides are small chains of amino acids (the building blocks that make up proteins) linked together. Our peptide is a chain of 7 amino acids attached to a fluorescent dye called FITC (like the one used by your eye doctor).

The investigators have prepared special "fluorescent peptides", that will "glow" when a special light is used that should help us separate normal tissue from abnormal tissue. In this study, the investigators will apply the special fluorescent peptides by a spray catheter to your esophagus to help us target you biopsies. Both routine and targeted biopsies will be taken as your endoscopist feels is indicated.
This is a phase 1b study. This means that although the investigators have applied the peptide to 25 people in our first research study, the investigators still need to learn more about "fluorescent peptide" in people. The Food and Drug Administration (FDA) has not approved this agent, but is allowing us to test it in this study. The main goal of this study is to see if the peptide "glows" well and if the investigators can take pictures of the areas that do glow.
This is a research study of the peptide and our ability to see it "light up or fluoresce". Being in this study and applying this peptide won't change how your biopsies are taken nor how your endoscopy is done.

What is being measured
The primary outcome is the main question the study is designed to answer.
validate binding of the fluorescent-labeled peptide to esophageal neopla
The overall aim of this research project is to develop the use of fluorescent-labeled peptides that affinity bind to pre-cancerous mucosa in the digestive tract for use as an imaging agent to guide endoscopic biopsy or endoscopic mucosal resection (EMR). This particular study is a phase Ib, vaidation of efficacy of the topically applied peptide and continuing assessment of safety.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing GI heptapeptide in people with Barrett's Esophagus, run by University of Michigan at 1 site 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 4 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 8 Oct 2015. 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 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.
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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
validate binding of the fluorescent-labeled peptide to esophageal neopla (time frame: 1.5 years). 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 NCT01630798, which also lists 1 linked publication.
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 8 Oct 2015.
