Hyper-Spectral Endoscopy for Detection of Early Neoplasia in Barrett's

Status Not yet recruiting

Clinical Trial Summary

The goal of this clinical trial is to assess the efficacy of hyperspectral endoscopic imaging to distinguish neoplasia from non-dysplastic Barrett's oesophagus in vivo. The main outcome measures are: 1) Classification of spectral patterns corresponding to neoplastic vs non-neoplastic Barrett's; 2) Image quality assessed by the endoscopist by VAS rating the level of confidence in delineating the area of interest; 3) Time to perform hyperspectral imaging; 4) Quantification of molecular biomarkers in endoscopic areas with neoplastic spectral patterns. Participants will firstly undergo a standard endoscopy, followed by another endoscopy using the experimental HySe device. Subsequently, patients will receive biopsies according to Seattle protocol, and up to 6 additional (optional) snap frozen research biopsies.

Clinical Trial Description

This trial is designed to evaluate the feasibility of hyperspectral endoscopic imaging in vivo. The team has developed a custom hyperspectral endoscope based around a commercially available, standard-of-care endoscopy stack from Olympus (Tokyo, Japan). In this system, the original gastroscope, video processor and display are used with a modified light source that incorporates a laser with tunable wavelength for illuminating the scene through the endoscope. A live video feed from the gastroscope is displayed on the endoscopy theatre monitors and can be acquired and saved in the native video acquisition system. Given that it is essential in the pilot study to assess the detection of neoplastic lesions in a small patient cohort, we will artificially enrich for patients with early neoplasia by including patients with previously recognized early neoplasia within Barrett's oesophagus (high grade dysplasia and intramucosal adenocarcinoma). These patients will receive a clinically indicated endoscopy to be assessed to determine eligibility for endoscopic treatment, and imaging would be done at this time point. This will allow the team to have sufficient number of outcomes to have preliminary data on diagnostic accuracy and be able to power future studies in non-enriched patient cohorts. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
