Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

57

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Long Segment Barrett's Esophagus (LSBE)
Subjects diagnosed with Long Segment Barrett's Esophagus (LSBE)
Device: NaviCam Detachable String Capsule
Subjects will swallow the NaviCam capsule with 20 ml water while positioned in the upright position. Once the capsule reaches the gastric cardia, the string will slowly be pulled up to systematically inspect the Z-line and upper, middle, and lower thirds of the esophagus guided by real-time viewing and by moving the capsule solely with the tether. Images will be captured at a rate of 2 frames per second.
Experimental: Short Segment Barrett's Esophagus (SSBE)
Subjects diagnosed with Short Segment Barrett's Esophagus (SSBE)
Device: NaviCam Detachable String Capsule
Subjects will swallow the NaviCam capsule with 20 ml water while positioned in the upright position. Once the capsule reaches the gastric cardia, the string will slowly be pulled up to systematically inspect the Z-line and upper, middle, and lower thirds of the esophagus guided by real-time viewing and by moving the capsule solely with the tether. Images will be captured at a rate of 2 frames per second.
Experimental: Gastro Esophageal Reflux Disease
Subjects with Gastro Esophageal Reflux Disease (GERD) who are eligible for Barrett's Esophagus screening
Device: NaviCam Detachable String Capsule
Subjects will swallow the NaviCam capsule with 20 ml water while positioned in the upright position. Once the capsule reaches the gastric cardia, the string will slowly be pulled up to systematically inspect the Z-line and upper, middle, and lower thirds of the esophagus guided by real-time viewing and by moving the capsule solely with the tether. Images will be captured at a rate of 2 frames per second.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Detection of Columnar lined epithelium in the esophagus
Time Frame: From start of procedure to removal of capsule, assessed up to 30 minutes timeframe from start to end of procedure..
Detection of Columnar lined epithelium in the esophagus
From start of procedure to removal of capsule, assessed up to 30 minutes timeframe from start to end of procedure..

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Visual Analogue Scale (VAS)
Time Frame: 30 minutes post-procedure
Visual Analogue Scale (VAS) is an 11-tem questionnaire assessing pain, where 0 represents the "worst experience" and 10 the "best experience". Total scores range from 0 - 110, lower scores indicating lower pain and higher scores indicating greater pain.
30 minutes post-procedure
Spielberger State-Trait Anxiety Inventory (STAI-6)
Time Frame: Baseline, 30 minutes post-procedure
Patient anxiety will be measured using the shorter 6 item form of the Spielberger State-Trait Anxiety Inventory (STAI-6), with a score over 40 as a threshold for clinically significant anxiety
Baseline, 30 minutes post-procedure
Impact of Events Scale (IES)
Time Frame: Baseline, 7 days post-procedure
The Impact of Events Scale (IES) will be used to assess distress associated with the procedure and procedure acceptability. The IES is rated on a scale of 0 (not at all) to 4 (extremely), with higher scores indicating a greater level of distress.
Baseline, 7 days post-procedure

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.

For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
