Study type
Interventional
Description of intervention(s) / exposure
Crossover trial comparing dispersion of fluticasone between novel nasal adaptor and a standard nasal spray.

Methods:
An experienced ENT surgeon will perform the endoscopic procedures for the placement and removal of filter paper from the sinuses at an ENT clinic. The total duration of the testing session will take approximately 45 minutes.
To measure the dispersion achieved by the novel nasal adaptor, filter paper circles of diameter 5 mm will be placed into the sinonasal cavities of 15 recovered post-surgery chronic rhinosinusitis patients under endoscopic guidance (frontal recess, posterior wall of maxillary sinus and front face of sphenoid inferior to the sphenoidotomy). Fluticasone (125 ug) will be administered through a metered dose inhaler with the novel adapter attached. The angle of the administration into the anterior nares will be delivered and carefully controlled by the investigators. This procedure will take approximately 15 minutes.
After administration, the filter paper circles will be retrieved. Patients will then be asked to perform a saline lavage and new filter dots will be placed in the same sinonasal locations. This part will take approximately 15 minutes.
The same procedure will be repeated with a standard spray (more details are provided in the control treatment field). This part of the testing will take approximately 15 minutes.
Intervention code [1] 324882 0
Treatment: Devices
Comparator / control treatment
Metered device inhaler with a novel adapter will be compared with a standard nasal spray.

The order in which the devices will be tested will be randomised.

To measure the dispersion achieved by the standard spray, filter paper circles of diameter 5 mm will be placed into the sinonasal cavities as described above. The standard nasal spray contains 25 ug of fluticasone per puff. To provide similar fluticasone doses between the novel device and standard spray, three puffs (3x 25 ug) will be required. The angle of the administration into the anterior nares will be delivered and carefully controlled by the investigators. After administration, the filter paper circles will be retrieved.
This procedure will take approximately 15 minutes.

Efficacy
Statistical methods / analysis
Drug levels from the filter papers will be measured using HPLC and statistically analysed using R software. Comparisons will be made between devices and between the three sinus sites.

An adjusted Meltzer Clinical Trial Patient Preference Questionnaire (CTPPQ) will be used to access satisfaction, preference and compliance of the devices. Annova tests will be conducted to analyze between groups using GraphPad Prism (version 6).
