Evaluation of the Safety and Performance of a Bioresorbable Nasal Dressing Containing Mometasone Furoate (MF) (ENHANCE II)

December 10, 2025 updated by: Polyganics BV

A Multicenter, Randomized, Controlled Study to Evaluate the Safety and Effectiveness of a Bioresorbable Nasal Dressing Containing Mometasone Furoate Compared to a Steroid-eluting Sinus Stent

The primary objective of the study is to evaluate the safety and effectiveness of OCEAN as an adjunct aid in wound healing after nasal/sinus surgery and to demonstrate that OCEAN is non-inferior compared to a steroid-eluting sinus stent.

Conditions

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

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.

Detailed Description

A multicenter, randomized, single-blinded, controlled, intra-patient non-inferiority study enrolling 110 subjects at up to 13 sites in the United States.

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

  • Adult

Exclusion Criteria:

  1. Subject with a history of chronic epistaxis or experienced a significant epistaxis event (defined as epistaxis requiring medical intervention) in the past 3 months.

  10. Subject that requires nasal ointments or creams at time of device placement.
  11. Subject with a neurological, medical, psychiatric condition, or social circumstance that would potentially increase risk, interfere with study participation, or confound interpretation of study data.
  12. Subject with plans to (or otherwise anticipate the need to) undergo an ENT procedure within the 90-day study follow-up.
  13. Subject participating in another clinical research study (within 30 days prior to screening up to 90 days post-operative).
  14. Subject that used any form of biologics within 90 days prior to sinus surgery and during follow-up to day 25.

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.
Outcome Measure
Measure Description
Time Frame
Rate of Serious Adverse Events
Time Frame: Up to Day 25
Rate of serious adverse events related to the use of OCEAN bioresorbable nasal dressing.
Up to Day 25
Endoscopic Assessment
Time Frame: Day 25
Endoscopic assessment of wound healing to compare test-treated and control-treated cavities.
Day 25

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.
