Pilot Study for TCE Imaging of the Esophagus Using an OFDI Capsule With a Compact Imaging System
What this study is about
The goal of this research is to test a distal scanning capsule and a compact redesigned version of the OFDI imaging system in healthy and BE participants to assess ease of use, safety and feasibility in preparation for its use in a conducted at multiple hospitals clinical trial.

Interventions
DEVICE
Experimental OFDI Imaging
Imaging of the esophagus with a compact OFDI system and distal scanning catheter
Primary outcome measures
Assessment of quality and performance of Compact Imaging System (CIS)
Time frame: 5-7 Minutes of imaging
Images obtained from the CIS will be assessed for quality and compared to images acquired from the previous imaging system
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- A previous diagnosis of BE (not an inclusion criteria for healthy volunteers)
- Participants 18 years and older with a previous diagnosis of GERD
- Participants 14 years and older with a previous diagnosis of EoE (not an inclusion criteria for healthy volunteers)
- Health participants over the age of 18 but less than 85 years of age
- Participants must be able to give informed consent
- Participants must have no solid food for 4 hours prior to the procedure, and only clear liquids for 2 hours prior to the procedure.
Exclusion criteria
- Participants over 85 years of age
- Participants with the inability to swallow pills and capsules.
- Participants with a strong gag reflex
- Esophageal fistula and/or esophageal strictures with a stricture diameter that is smaller than the diameter of the capsule.
- Participants who are pregnant. In case of women of child bearing age, we will ask them if they are pregnant and if unsure; ask them to take a pregnancy test.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
