About this study

Official title: Outpatient Colonoscopy: Demonstrating Effective Salvage of Inadequate Colonoscopies Utilizing the Pure-Vu EVS System

The aim of this study is to demonstrate that the use of the Pure-Vu EVS System can salvage inadequately prepared optical colonoscopies (OCs) to adequate OCs.

Read the detailed description

The primary objective of this study is to demonstrate the reduction of inadequate colonoscopies when Pure-Vu EVS System is used to salvage inadequately prepped colons as defined by the multi-society guidelines (USMSTF).

Being tested
Pure-Vu EVS

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pure-Vu EVSDevice

    Subjects will be enrolled until 115 inadequate bowel prep cases via SOC are accrued and subsequently treated with Pure-Vu EVS. Inadequate OCs defined as such if any of the following are met:

    • Boston Bowel Preparation Score (BBPS) < 6 (Adequacy is defined as BBPS of 2 or greater in each segment)
    • Inability to identify > 5mm polyps

Pure-Vu EVSOtherRate of incomplete colonoscopies due to inadequate preparation salvaged to adequate colonoscopies with the use of the Pure-Vu EVS System. Inadequate OCs defined as such if any of the following are met: * BBPS < 6 (Adequacy is defined as BBPS of 2 or greater in each segment) * Inability to identify > 5mm polyps The estimated rate of salvaged preparations will be calculated and presented with exact one-sided 95% confidence interval: Number of preps inadequate with SOC and adequate after Pure-VU EVS System / Number of preps inadequate with SOC. The lower bound will be compared to a 35% performance goal.

What is being measured

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

  1. Rate of incomplete colonoscopies

    Rate of incomplete colonoscopies due to inadequate preparation salvaged to adequate colonoscopies with the use of the Pure-Vu EVS System.

    Inadequate OCs defined as such if any of the following are met:

    • BBPS < 6 (Adequacy is defined as BBPS of 2 or greater in each segment)
    • Inability to identify > 5mm polyps The estimated rate of salvaged preparations will be calculated and presented with exact one-sided 95% confidence interval: Number of preps inadequate with SOC and adequate after Pure-VU EVS System / Number of preps inadequate with SOC.

    The lower bound will be compared to a 35% performance goal.

    Measured: Day 0 (Procedure Day)

Secondary outcomes (13)
  1. Assessment of Screening

    The following secondary endpoint will be assessed:

    Number of polyps and adenomas: type, location, size, pathology and morphology

    Measured: Day 0 (Procedure Day)

  2. Assessment of Screening

    Boston Bowel Prep Score (BBPS) before and after Pure-Vu EVS use. Throughout the procedure, the study endoscopist will be requested to document the pre-cleansing BBPS and post- cleansing BBPS for each colon segment.

    Measured: Day 0 (Procedure Day)

  3. Procedural Outcome

    Sedation type The type of sedation will not be dictated by the study but will be documented.

    Measured: Day 0 (Procedure Day)

  4. Procedural Outcome

    Cecum Intubation Rate

    Measured: Day 0 (Procedure Day)

  5. Assessment screening

    Polyp Miss Rate (PMR)

    Measured: Day 0 (Procedure Day)

  6. Assessment screening

    Adenoma Detection Rate (ADR)

    Measured: Day 0 (Procedure Day)

  7. Assessment screening

    Adenoma Miss Rate (AMR)

    Measured: Day 0 (Procedure Day)

  8. Assessment screening

    Adenoma Per Colonoscopy (APC)

    Measured: Day 0 (Procedure Day)

  9. Assessment screening

    Adenomas Per Positive Patient (APP)

    Measured: Day 0 (Procedure Day)

  10. Assessment screening

    Sessile Serrated Adenoma Detection Rate

    Measured: Day 0 (Procedure Day)

  11. Assessment Screening

    Polyp Detection Rate (PDR)

    Measured: Day 0 (Procedure Day)

  12. Procedural Outcomes

    Procedure Time: Time to cecum and withdrawal time

    Measured: Day 0 (Procedure Day)

  13. Procedural Outcomes

    Intraprocedural tools The type of Intraprocedural tools will not be dictated by the study but will be documented.

    Measured: Day 0 (Procedure Day)

Questions about this trial

What is this clinical trial studying?

A study testing Pure-Vu EVS in people with Colorectal Screening, run by Motus GI Medical Technologies Ltd 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 2 inclusion and 9 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: stopped early, as of the sponsor's last update on 13 May 2024. 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.

Are results available for this study?

The study was stopped early (reason given: Strategy changed). Results are not available in the source record.

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?

Rate of incomplete colonoscopies (time frame: Day 0 (Procedure Day)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 13 May 2024.
