About this study

Official title: Minimally-Invasive Detection of Barrett's Esophagus and Barrett's Esophagus Related Dysplasia/Carcinoma by a Sponge on String Device

This study is being done to collect data on the potential use of a sponge on a string device as a non-invasive tool in evaluating patients with Barrett's Esophagus compared to healthy controls.

Read the detailed description

This study will be conducted in two phases: Phase 1 and Phase 2. Phase 1 will consist of determining the most optimal sponge on a string design (25 mm sponge 20 pores/inch or 25 mm sponge 10 pores/inch) chosen based on participant acceptance, tolerability, mucosal irritation and DNA yield, using a randomized factorial design pilot trial. Participants will first undergo the sponge on a string test followed by clinical endoscopy. Following completion of Phase 1 trial, the most optimal sponge on a string configuration will be chosen for Phase 2. Phase 2 will be conducted using a single size sponge with the same porosity configuration selected from Phase 1. Study procedures, testing and follow up will be the same as Phase 1.

Being tested

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Subjects That Would Have This Procedure Again

    Number of subjects that answered yes to the self-reported question "Would you choose to have this procedure again to screen for Barrett's esophagus?"

    Measured: Within 24 hours of the capsule sponge administration

  2. Tolerability of Swallowing the Sponge Device

    Measured using a self-reported 5-item tolerability assessment rating discomfort during the procedure on a Likert scale of 0-10; 10 representing the "worst experience" and 0 the "best experience." This scale allows a comprehensive and individual assessment of the degree of pain, choking, gagging, anxiety and overall experienced during the procedure.

    Measured: Within 24 hours of the capsule sponge administration

  3. Mucosal Irritation

    Measured using a mucosal injury score (ranging from 1=no trauma to 5=severe) was scored from video recordings of the subsequent endoscopy conducted

    Measured: Within 24 hours of the capsule sponge administration

  4. DNA Yield

    Total amount of DNA obtained from esophageal cytology specimens collected by the capsule sponge devices.

    Measured: Within 24 hours of the capsule sponge administration

Secondary outcomes (2)
  1. Sensitivity of Barrett's Dysplasia Detection

    The sensitivity methylated DNA markers detected by the capsule sponge, in making a diagnosis of BE related dysplasia will be assessed using endoscopic surveillance biopsy histology as a gold standard.

    Measured: Within 24 hours of the capsule sponge administration

  2. Specificity of Barrett's Dysplasia Detection

    The specificity of methylated DNA markers detected by the capsule sponge, in identifying subjects without a diagnosis of BE related dysplasia will be assessed using endoscopic surveillance biopsy histology as a gold standard.

    Measured: Within 24 hours of the capsule sponge administration

Where is the study taking place?

The record lists 6 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.
