Trial summary

The Eustachian tube is a narrow tube which links the back of the nose to the middle ear. Eustachian tube dysfunction may occur when the mucosal lining of the tube is swollen, or does not open or close properly. Read more about this study

About this study

Official title: Eustachian Tube Dilation Using an Angioplasty Balloon - a Pilot Safety Study

The Eustachian tube is a narrow tube which links the back of the nose to the middle ear. Eustachian tube dysfunction may occur when the mucosal lining of the tube is swollen, or does not open or close properly. It can occur after the start of a cold and other nose, sinus, ear and throat infections causing ear pain and pressure, fullness, cracking/popping sounds. This is an ubiquitous healthcare problem, affecting children and adults, that can lead to severe consequences including hearing loss, chronic otitis media, tinnitus, and vertigo. Numerous studies have consistently failed to support the effectiveness of medical managements. Pressure equalizing tubes are considered a temporary solution that does not treat the underlying pathology. More recent preliminary evidence of using inflation of a noncompressible balloon in the eustachian tube improved clinical outcomes, patients' symptoms and quality of life. This eustachian dilation catheter is not accessible in Canada since the device and procedure is not covered by OHIP (Ontario health insurance plan) or any other health insurance in Canada. In a cadaver study, we have evaluated using an endovascular balloon (Balloon that is used to dilate (expand) vessels) for eustachian tube dilation, which only costs about 10% of the eustachian tube dilation device. This endovascular balloon is Health Canada approved, but not for this specific use. We therefore want to conduct a pilot safety study with the main goal of assessing feasibility of eustachian tube dilation with the endovascular device.

What is being measured

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

  1. Succesfull procedure

    • Feasibility to perform the procedure after ear surgery with no local complication and within 15-20 minutes

    Measured: 20 minutes

Secondary outcomes (3)
  1. CT

    • Safety evaluated after the procedure CT scan. Complications (adverse and serious adverse events related to the device or procedure)

    Measured: 5 minutes

  2. ETDQ - 7 (Eustachian Tube Dysfunction Questionnaire - Item 7)

    • Mean change in overall ETDQ-7 scores from baseline at 2- and 6-months follow-up

    Measured: 2 minutes

  3. Endoscopic evaluation

    Safety evaluated after the procedure by endoscopic examination and CT scan. Complications (adverse and serious adverse events related to the device or procedure)

    Measured: 5 minutes

Questions about this trial

What is this clinical trial studying?

A study testing Eustachian tube dilation in people with Eustachian Tube Dysfunction and Eustachian Tube Dysfunction of Both Ears, run by Sunnybrook Health Sciences Centre at 1 site in Canada.

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 3 inclusion and 7 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 26 Oct 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 Canada. 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?

Succesfull procedure (time frame: 20 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 NCT04809753, 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 26 Oct 2022.
