About this study
Official title: A Prospective, Multi-Center, Randomized, Controlled, Subject-Blinded Study to Evaluate the Safety and Effectiveness of AdvaCoat Sinus Gel Following Endoscopic Ethmoid Sinus Surgery
The purpose of this study is to evaluate the safety and effectiveness of AdvaCoat® sinus gel, a nasal/sinus dressing, for adhesion prevention following endoscopic ethmoid sinus surgery. Subjects were randomized to receive AdvaCoat applied to the right or left middle meatus tissues and Merogel applied to the middle meatus tissues on the opposite side.
Read the detailed description
Chronic rhinosinusitis is a very common condition, affecting 35 million Americans each year. All paranasal sinuses need ventilation to prevent infection and inflammation. Sinus ventilation occurs through the ostia into the nose. When rhinosinusitis occurs, the mucous membranes of the sinuses become swollen, resulting in ostia closure. Functional endoscopic sinus surgery (FESS) is a minimally invasive surgical procedure that opens the sinus ostia.
The most common unwanted side effect of the FESS procedure is the formation of adhesions (fibrous bands) in the area of surgery. These bands (adhesions) can prevent proper ventilation and drainage from the paranasal sinuses.
Various hyaluronan based biomaterials are now available and in common use to provide a post-surgical nasal dressing which is absorbable, can prevent adhesion formation, and eliminate the pain and tissue abrasion caused by removal of non-absorbable nasal packing.
AdvaCoat is a bioresorbable hyaluronan gel that conforms to mucosal surfaces and provides a post-surgical nasal dressing to prevent adhesion formation as tissues heal.

| 2 | Active comparator | Merogel Injectable Bioresorbable Nasal Dressing compared to AdvaCoat Receives: Device: Merogel Injectable |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Adhesion as Measured by the Synechia (Adhesion) Scale
Synechia (adhesion) scale range of 0 = No visible synechia to 3 = Complete scarring between the middle turbinate and lateral nasal wall was used in the assessment.
Measured: Post-operative through 60 days
Number of Participants With Solicited and Recorded Adverse Events
All reported events were coded to a standard set of terms using the MedDRA adverse event dictionary. Adverse events were listed and summarized.
Measured: Post-operative through 60 days

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?
Yes. Results are posted in the registry (first posted 23 Apr 2009). 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?
Number of Participants With Adhesion as Measured by the Synechia (Adhesion) Scale (time frame: Post-operative through 60 days). The study lists 2 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 23 Apr 2009; AzTrials last refreshed its copy on 7 Nov 2026.
