Novel Method for Removal of Orally Deposited Inhaled Fluticasone Propionate (EVOOW)
A Proof-of-Concept Study of a Novel Method for Removal of Residual Oropharyngeal Inhaled Corticosteroid Deposits in Asthma
調査の概要
詳細な説明
The objective of this study is to test a novel, Extra Virgin Olive-Oil-based Water (EVOOW) mix--designed to leverage ICS physicochemical molecular properties-- for improved removal of orally deposited Fluticasone Propionate (FP) delivered via a Metered Dose Inhaler (MDI) in patients with asthma.
The investigators hypothesize that EVOOW mouthwash will return a greater amount of orally deposited FP than Water rinse. Furthermore, because upper airway ICS deposition from a pressurized MDI is independent of inspiratory flow, the efficacy of EVOOW is not influenced by the presence of asthma.

Participants will be administered 1 puff of 220 micrograms FP, via Metered Dose Inhaler, without inhaling into the lungs.
Participants will rinse and gargle with 3 consecutive aliquots (20ml each) of either Water (W).
Participants will rinse and gargle with 3 consecutive aliquots (20 ml each) of an equal parts EVOO and Water mixture.

FP concentration in mouthwashes (ng/mL)
時間枠:data collected during each of two study visits, 7-10 days apart
|
The primary outcome measure is FP concentration in mouthwashes, measured using mass spectrometry.
The primary comparison of interest is the treatment-by-group interaction, representing the differential treatment effect (EVOOW vs. Water) between asthma and healthy participants.
3 separate 20ml aliquots will be administered and collected during each of 2 study visits, 7-10 days apart.

FP drug extraction fraction (EFR)
時間枠:data collected during each of two study visits, 7-10 days apart
|
3 separate 20ml aliquots will be administered and collected during each of 2 study visits, 7-10 days apart. FP drug extraction fraction (EFR) calculated as ([measured FP concentration, ng/ml]/220,000 ng FP delivered)*100 on each of the aliquots. |

FP/Water EFR
時間枠:data collected during each of two study visits, 7-10 days apart
|
3 separate 20ml aliquots will be administered and collected during each of 2 study visits, 7-10 days apart. FP/Water EFR trend across sequential aliquots, analyzed in the same fashion as the primary outcome. |
