December 7, 2022 updated by: Li-Xing Man, University of Rochester

A Prospective, Randomized, Controlled Trial of Steroid Delivery to the Frontal Sinus Opening With a Bioabsorbable Steroid Releasing Implant vs. a Bioabsorbable Nasal Dressing With Added Steroid

The purpose of this study is to compare how two different post-surgical treatments that both deliver steroids to the frontal sinus opening affect your healing after frontal sinus surgery.

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a single center, randomized & controlled trial comparing the efficacy of the Propel mini stent or Propel contour stent vs. Nasopore impregnated with Triamcinolone Acetonide at reducing frontal sinus opening stenosis and polypoid edema after endoscopic sinus surgery in patients with chronic rhinosinusitis with polyposis. Eligible subjects who undergo standard of care bilateral frontal sinusotomy will have each frontal sinus randomly assigned to either a Propel mini or contour steroid eluding stent or a Nasopore nasal dressing impregnated with 2.5 ml of Triamcinolone Acetonide 40 mg/ml. Specific Propel stent will be chosen based on the shape of frontal sinus opening and best fit as decided by the operating Surgeon. Patients will be reassessed on approximately post-operative day 7, 14, 30, 90 days, 6 months, and 12 months at their standard of care follow-up visits. On the day 14 visit, the frontal sinus Propel stent and Nasopore will be completely removed per Standard of care. Video will be taken of the frontal sinus opening, and assessed for scarring/adhesions, presence of polypoid edema, frontal sinus patency, need for oral steroids or other interventions. Additionally, endoscopic scoring of frontal sinus by the above measures will be evaluated by 2 independent sinus surgeon reviewers. The reviewers will also be asked to rank the two frontal sinus openings as better, same or worse, compared to the opposite side

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Bioabsorbable steroid releasing sinus implant & nasal dressing impregnated with steroid
Patients will undergo bilateral endoscopic sinus surgery which will include bilateral frontal sinusotomy of Draf 2a or 2b type as previously described in the literature. At the conclusion of the procedure, if the patient still meets all inclusion criteria, one frontal sinus will be randomly assigned using the envelop method to receive a bioabsorbable steroid releasing implant and the other frontal sinus will receive a bioabsorbable nasal dressing impregnated with steroid
Device: Bioabsorbable steroid releasing sinus implant
After completion of indicated frontal sinus surgery, patients will have a bioabsorbable steroid releasing implant placed in the frontal sinus opening, which will remain in place for 14 days.
Device: Bioabsorbable nasal dressing impregnated with steroid
After completion of indicated frontal sinus surgery, patients will have a bioabsorbable nasal dressing impregnated with steroid placed in the frontal sinus opening, which will remain in place for 14 days.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
