About this study

Official title: Surgical Reduction of the Inferior Turbinate Using a Coblation® Device for Treatment of Nasal Obstruction: A Prospective, Multi-center Clinical Study

The primary goal of this post-marketing surveillance study is to assess whether surgical turbinate reduction performed using a Coblation® device is associated with reduced nasal obstruction symptoms.

Read the detailed description

Chronic rhinitis, or inflammation of the nasal mucosa, is one of the most common causes of nasal obstruction in the pediatric population. Chronic rhinitis may result in mucous gland hypertrophy, engorgement of the vascular system and deposition of collagen in the nasal mucosa. These changes occur most prominently in the inferior turbinate, causing enlargement and nasal obstruction. In children, inferior turbinate hypertrophy is associated with a greater degree of nasal obstruction relative to adults because of their small nasal anatomy.

Cases that do not respond to conservative treatments may be considered for one of many surgical procedures, including turbinate excision, submucosal resection, submucosal cautery, laser treatment, cryosurgery, powered microdebridement, or radiofrequency-based ablation. Clinical studies have shown that bipolar radiofrequency-based plasma (Coblation®) devices are capable of creating focal submucosal lesions with minimal or no damage to structures adjacent to the treated area. At present, however, this technique has not been formally evaluated in children. This study will investigate whether surgical turbinate reduction performed using a Coblation device is associated with reduced nasal obstruction symptoms that has failed to improve with other treatment methodologies.

What is being measured

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

  1. Change in nasal obstruction symptoms at 6-weeks post surgery as measured using a validated health-related quality of life questionnaire (SN5) compared to nasal obstruction symptoms measured before surgery using the same questionnaire.

    Measured: 6 weeks, 6 months, 12 months

Secondary outcomes (2)
  1. Morbidity by determining the frequency, type, and severity of any observed adverse events through 12 months following surgical treatment.

    Measured: Through 12 months

  2. To assess durability of treatment using: a. Self-reported obstructive symptoms measures b. Physical examination measures, d. Blinded evaluation of anterior rhinoscopy images

    Measured: 6 weeks, 6 months, 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Surgical turbinate reduction procedure in people with Chronic Rhinitis and Inflammation of the Nasal Mucosa, run by ArthroCare Corporation at 5 sites 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 6 inclusion and 19 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 26 Aug 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

The study was stopped early. 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?

Change in nasal obstruction symptoms at 6-weeks post surgery as measured using a validated health-related quality of life questionnaire (SN5) compared to nasal obstruction symptoms measured before surgery using the same questionnaire. (time frame: 6 weeks, 6 months, 12 months). 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 NCT00737906, which also lists 2 linked publications.

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 Aug 2015.
