About this study
Official title: Safety and Efficacy of Nebulized Nasal Steroids for the Treatment of Chronic Rhinosinusitis
The goal of the proposed project is to assess the efficacy, safety, and patient experience of budesonide administered via the NasoNeb system for medical management of CRS. The authors propose a randomized controlled trial of nebulized budesonide via the NasoNeb compared against budesonide lavage.
Read the detailed description
Chronic rhinosinusitis is primarily an inflammatory disorder affecting up to 1 in 8 individuals and causing economic burden of greater than 13 billion USD. The NasoNeb is FDA approved for the nasal administration of medications; however, it has been scarcely studied in the existing literature. Many patients are intolerant of or non-compliant with other modalities of nasal steroid administration, and the NasoNeb represents a potential new treatment method for these patients.
Participants will be provided with either a NasoNeb machine or NeilMed lavage bottle, and a prescription for a 42-day supply of 0.5 mg budesonide packets, to be used twice daily. For the NasoNeb, each dose will be dissolved in 10 mL saline with 5 mL nebulized solution being applied to each nasal cavity. This dose was chosen given the historical evidence of efficacy of budesonide 0.5mg daily application via saline lavage.
For the lavage, each budesonide dose will be dissolved in 240 mL saline. Participants will be shown proper use of the NasoNeb machine or lavage bottle at the time of enrollment and be given written instructions with links to video tutorials.

What is being measured
The primary outcome is the main question the study is designed to answer.
Sino-Nasal Outcome Test (SNOT-22)
SNOT-22 is a 22-question survey designed to measure the physical, functional, and emotional consequences of rhinosinusitis. It contains questions regarding symptoms commonly associated with sinonasal disease.
Subjects rate each question 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-22 total score ranges from a minimum score of 0 to a maximum score of 110, with higher scores representing worse outcome.
9 point difference in SNOT-22 reduction is defined as the minimally clinically important improvement.
Measured: week 6
Secondary outcomes (4)
Lund-Kennedy scores
Lund-Kennedy scores from nasal endoscopy will be recoded. The original LK system evaluates five components, each graded 0 to 2 for each side of nasal cavity. The score from both sides are summed up and for a total score ranging from 0-20 (10 points per side). Higher scores indicate more severe disease.
Modified scores will be used.
Measured: week 6
cosyntropin stimulation
Patients from both arms may volunteer for cosyntropin stimulation testing. This will be done to monitor for potential adrenal suppression related to treatment.
Cosyntropin testing yields a numerical value with units of mcg/dL. We will use a threshold of normal to be greater than or equal to 18 mcg/dL at the 60 minute test.
Measured: week 6
Clinical Global Impression - Improvement (CGI-I)
The primary outcome measure will be the rate of responders (as a percentage) to the intervention defined as the number of participants reporting 2 (Moderately Improved), or 3 (Much Improved) in the Clinical Global Impression of Improvement (CGI-I) assessed after 6 weeks of treatment divided by the total number of participants in each study group.
CGI-I asks subjects to rate their overall response to treatment using a 7-point Likert scale ranging from -3 to 3 ("Much Worse" to "Much Improved"). Participants responding 2 (Moderately Improved), or 3 (Much Improved) to the the CGI-I question "Compared to the start of the study, how would you rate your nasal breathing now", will be defined as responders to treatment.
Measured: week 3 and week 6
Sino-Nasal Outcome Test (SNOT-22)
SNOT-22 is a 22-question survey designed to measure the physical, functional, and emotional consequences of rhinosinusitis. It contains questions regarding symptoms commonly associated with sinonasal disease.
Subjects rate each question 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-22 total score ranges from a minimum score of 0 to a maximum score of 110, with higher scores representing worse outcome.
9 point difference in SNOT-22 reduction is defined as the minimally clinically important improvement.
Measured: week 3

The goal of the proposed project is to assess the efficacy, safety, and patient experience of budesonide administered via the NasoNeb system for medical management of CRS. The authors propose a randomized controlled trial of nebulized budesonide via the NasoNeb compared against budesonide lavage.
Detailed description
Chronic rhinosinusitis is primarily an inflammatory disorder affecting up to 1 in 8 individuals and causing economic burden of greater than 13 billion USD. The NasoNeb is FDA approved for the nasal administration of medications; however, it has been scarcely studied in the existing literature. Many patients are intolerant of or non-compliant with other modalities of nasal steroid administration, and the NasoNeb represents a potential new treatment method for these patients.
Participants will be provided with either a NasoNeb machine or NeilMed lavage bottle, and a prescription for a 42-day supply of 0.5 mg budesonide packets, to be used twice daily. For the NasoNeb, each dose will be dissolved in 10 mL saline with 5 mL nebulized solution being applied to each nasal cavity.

Time frame: week 6
SNOT-22 is a 22-question survey designed to measure the physical, functional, and emotional consequences of rhinosinusitis. It contains questions regarding symptoms commonly associated with sinonasal disease. Subjects rate each question 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-22 total score ranges from a minimum score of 0 to a maximum score of 110, with higher scores representing worse outcome. 9 point difference in SNOT-22 reduction is defined as the minimally clinically important improvement.

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 combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?
Sino-Nasal Outcome Test (SNOT-22) (time frame: week 6). It is what the study was designed to measure, not a finding.
