About this study

For removal of large flat lesions of the gastro-intestinal tract injection of a solution under the lesion creates a "safety" cushion and protects from damage to the gastrointestinal tract wall. Various solutions are currently used, but some of them are easy to inject but quickly dissipate (normal saline),other solutions are more longer lasting (hydroxypropyl methylcellulose, hyaluronic acid, etc) but are very difficult to inject and can be expensive and not always available. The investigators performed previously animal experiments which demonstrated that blood is easy to inject and creates a protective cushion which lasts longer than other fluids which are currently used for protective cushion creation.

For removal of large flat lesions of the gastro-intestinal tract injection of a solution under the lesion creates a "safety" cushion and protects from damage to the gastrointestinal tract wall. Various solutions are currently used, but some of them are easy to inject but quickly dissipate (normal saline),other solutions are more longer lasting (hydroxypropyl methylcellulose, hyaluronic acid, etc) but are very difficult to inject and can be expensive and not always available. The investigators decided to use blood drawn from the patient for injection under the lesion. The investigators performed previously animal experiments which demonstrated that blood is easy to inject and creates a protective cushion which lasts longer than other fluids which are currently used for protective cushion creation. Blood can also have local hemostatic action preventing from bleeding during polypectomy.

Being tested

What participants receive

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

  • Autologous blood injectionDrug

    Autologous blood will be drawn from the patient and then reinjected under the lesion to create a safety cushion

  • Normal salineDrug

    Normal saline will be injected under the lesion to create submucosal cushion

  • HPMCDrug

    Hydroxypropyl methylcellulose (HPMC) will be injected under the lesion to create submucosal cushion

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Autologous blood injection, Normal saline and HPMC in people with Large Polyps in the Gastrointestinal Tract, run by Johns Hopkins University 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 1 inclusion and 2 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 13 Sep 2017. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 Sep 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Duration of the Submucosal Cushion (time frame: Immediately after the procedure, Up to 5 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00583466, which also lists 1 linked publication.

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 Sep 2017.
