About this study

Official title: Feasibility and Safety of MiWEndo-assisted Colonoscopy:Pilot Study

The study involves the planned use of a new microwave-based device during colonoscopy procedures in a small group of patients to assess the preliminary safety of its use and lack of normal clinical practice modification. The device is a final design version, which has been previously tested in several preclinical studies, including: phantom studies, an ex vivo study with human tissues, and an in vivo study with animal model (pig).

Read the detailed description

This study is designed as a single-center prospective, non-comparative, first in human pilot safety and feasibility study with few patients, whereby data will be subject to an analytical description, rather than to a statistical treatment (refer to Statistical design and analysis).

In this study the principal aim is to assess the clinical safety of the device and the feasibility of its use in assisted colonoscopy. Relevant claims to verify in this study are that the device can be used without ADEs, without any change in the current clinical practice, as well as without any major difficulty by the endoscopist, neither in the preparation nor in the use of the device during exploration.

In addition, the study aims to gather real clinical data with the use of the device to optimise the processing software that will be key to demonstrate MiWEndo's performance on a subsequent clinical investigation (pivotal study).

Consequently, principal and secondary objectives of this investigation, are:

  • Principal objectives:
  • To assess the feasibility of performing a complete colonoscopy using the MiWEndo System.
  • To assess the safety of MiWEndo colonoscopy.
  • Secondary objectives:
  • To assess the perception of difficulty by the endoscopist when the device is used.
  • To assess the patient's comfort.
  • To collect data on polyp detection performance to guide possible further improvements of the software before starting the pivotal study.

What participants receive

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

  • MiWEndo-assisted colonoscopyDevice

    All colonoscopies will be performed with high-definition technology. The MiWEndo System (MiWEndo Solutions, Barcelona) will be fitted to the tip of the endoscope before colonoscopy is started and connected to the microwave processor unit. Endoscopies will be performed by experienced endoscopists who will be previously trained on the use of the MiWEndo System.

    At the beginning of the extubation, the MiWEndo System will be turned on. During extubation, each segment will be carefully examined with both white light and MiWEndo. In case one of them identifies a polyp, the exploration will be stopped and check if it has been detected by the alternative method as well. All the polyps will be resected and sent to the Pathological Department for histological analysis following the usual clinical practice. A stopwatch will be used to measure both total procedure time and withdrawal time.

What is being measured

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

  1. Number of incidents and adverse events

    To assess the safety of MiWEndo colonoscopy using the lexicon proposed by the American Society of Gastrointestinal Endoscopy (ASGE).

    Measured: During the procedure and up to 2 weeks after

  2. Number of mural injuries

    To assess the safety of MiWEndo colonoscopy according to the Sydney classification for deep mural injuries (DMI)

    Measured: During the procedure

  3. Rate of cecal intubation

    To assess the feasibility of performing a complete colonoscopy using the MiWEndo System. This parameter will be measured as complete colonoscopy (yes/no).

    Measured: During the procedure

  4. Length of colon explored

    In case cecum could not be reached, the distance will be measured (in cm).

    Measured: During the procedure

Secondary outcomes (4)
  1. Patients' comfort

    Subjective assessment from patient following the Gloucester 5-Likert scale, where 1 is no discomfort and 5 is extreme discomfort.

    Measured: Immediately after the procedure and 2 weeks after

  2. Time for reaching the cecum (or maximum explored colon length)

    Measured in minutes

    Measured: During the procedure

  3. Total time for completing the procedure

    Measured in minutes

    Measured: Immediately after the procedure

  4. Perception of difficulty

    Difficulty by the endoscopist subjectively assessed based on a 5-points Likert scale, where 0 is not difficult and 4 is very difficult.

    Measured: Immediately after the procedure

Questions about this trial

What is this clinical trial studying?

A study testing MiWEndo-assisted colonoscopy in people with Colorectal Cancer and Colorectal Polyp, run by MiWEndo Solutions S.L. at 1 site in Spain.

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 1 inclusion and 3 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: finished, as of the sponsor's last update on 30 Nov 2022. 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 Spain. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Number of incidents and adverse events (time frame: During the procedure and up to 2 weeks after). The study lists 4 primary outcomes in all. 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 30 Nov 2022.
