Effectiveness of Mometasone Nasal Irrigation for Chronic Rhinosinusitis

June 24, 2025 updated by: Washington University School of Medicine
Chronic rhinosinusitis (CRS) affects up to 12.5% of the US population and has a significant disease burden. The recommended medical management of CRS includes large-volume, low-pressure saline lavage, systemic antibiotics, and intranasal corticosteroids (INCS). While the efficacy and safety of INCS are well-established for the long-term management of CRS, penetration of INCS beyond the nasal vestibule and into the paranasal sinuses is limited. The aim of this study is to evaluate the effectiveness of mometasone furoate large-volume, low-pressure nasal irrigation for surgery-naive CRS patients.

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

Mometasone furoate nasal spray (MFNS) is a INCS that is used in the management of CRS. The overall goal of this proposed research project is to optimize topical delivery of MF to the paranasal sinuses in surgery-naive CRS patients through the use of high-volume, low-pressure nasal saline irrigation. The investigators will be conducting a single-site, double-blinded, placebo-controlled randomized clinical trial (RCT) in which we propose to evaluate the effectiveness of MF nasal irrigation compared to MF nasal spray.

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.

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 to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

12-weeks or longer of two or more of the following signs and symptom consistent with CRS:

  • mucopurulent drainage(anterior, posterior, or both)
  • nasal obstruction (congestion)
  • facial pain-pressure-fullness
  • and decreased sense of smell

AND inflammation documented by one or more of the following findings:

  • purulent mucus or edema in the middle meatus or ethmoid region
  • radiographic imaging showing inflammation of the paranasal sinuses.

Exclusion Criteria:

  • inability to speak or understand English
  • nasal polyps
  • history of nasal or sinus surgery
  • comorbid mucociliary conditions
  • dependence on prolonged corticosteroid therapy for comorbid conditions, such as asthma and chronic obstructive pulmonary disease
  • history of oral or systematic antibiotic use in the past 2 weeks

Arms and Interventions

Participant Group / Arm

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: Mometasone Furoate Nasal Irrigation
The study intervention will be mometasone furoate powder (1.2 mg/capsule) and placebo nasal spray. The placebo nasal spray will contain the same inert ingredients found in MF nasal spray: glycerin, microcrystalline cellulose and carboxymethylcellulose, sodium citrate, citric acid, benzalkonium chloride, and polysorbate 80. The placebo nasal spray will be packaged identically to the mometasone nasal spray. Participants will be required to dissolve the contents of two capsules into an 8-ounce (240 mL) sinus rinse bottle along with the saline rinse. All participants will be instructed to perform the following once daily: irrigation of both right and left nasal cavity with one-half of the contents of the nasal rinse followed by 2 sprays per nostril of the nasal spray.
Drug: Mometasone Furoate Nasal Irrigation
Participants will undergo an 8-week treatment course that includes nasal saline irrigation with mometasone powder and placebo nasal spray.
Active Comparator: Mometasone Nasal Spray
The study intervention will be mometasone nasal spray (50 mcg/spray) and placebo nasal irrigation. The placebo will contain lactose monohydrate and will be supplied in capsules identical to the budesonide capsules. Participants will be required to dissolve the contents of the two capsules into an 8-ounce (240 mL) sinus rinse bottle along with the saline rinse. All participants will be instructed to perform the following once daily: irrigation of both right and left nasal cavity with one-half of the contents of the nasal rinse followed by 2 sprays per nostril of the nasal spray.
Drug: Mometasone Nasal Spray
Participants will undergo an 8-week treatment course that includes placebo saline irrigation with mometasone nasal spray.

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
Change in Sino-Nasal Outcome Test Scores (SNOT-22)
Time Frame: Change from Baseline to Week 8

The change in Sino-Nasal Outcome Test scores (SNOT-22) scores pre- and post-treatment between the two arms was measured. The Sino-Nasal Outcome Test asks subjects to rate how "bad" their rhinosinusitis is by using a 0-5 point scale with 0=no problem, 1=very mild problem, 2=mild or slight problem, 3=moderate problem, 4=severe problem, 5=problem as bad as it can be. The SNOT includes 22 questions (symptoms and social/emotional consequences of rhinosinusitis), each of which are rated from 0 to 5 for a minimum score of 0 to maximum score of 110, with higher scores representing worse outcome.

All relevant time points used in the calculation in the Time Frame (e.g., 'baseline and 8 weeks")
Change from Baseline to Week 8

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.
Outcome Measure
Measure Description
Time Frame
Number of Participants Who Score <3 on the Clinical Global Impression Scale
Time Frame: Week 8
CGI asks subjects to rate their overall response to treatment using a 7-point Likert scale with anchors of 1=very much improved, 4=no change, and 7=very much worse.
Week 8
Change in Nasal Endoscopic Findings Using the Lund-Kennedy Grading System
Time Frame: Change from Baseline to Week 8

A board-certified otolaryngologist will perform a nasal endoscopic examination pre- and post-intervention and findings recorded using the Lund-Kennedy grading system.

The The Lund Kennedy System grades the pathologic state of the nasal cavity based on the presence of polyps, nasal discharge, and mucosal edema.

Polyps graded from 0 to 2 (0=absent, 1=limited to middle meatus, 2=extending to nasal cavity) Discharge graded from 0 to 2 (0=absent, 1=thin/clear, 2=thick) Edema graded from 0 to 2 (0=absent, 1=mild/moderate, 2=polypoid degeneration). Scores are added for each side of the nose with a minimum score of 0 and maximum score of 12 with higher scores indicating more severe sinonasal inflammation.
Change from Baseline to Week 8
