After a nasal allergen challenge it should be possible to measure markers of inflammation that may be useful to assess the properties of future drugs. If these markers are reproducible and impacted by the study drugs they could be useful for future drug development.

Condition Intervention Phase
Allergic Rhinitis
Drug: Ibuprofen
Drug: Fluticasone propionate
Drug: Placebo
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Double Blind (3rd Party Open), 3-Way Crossover Study To Explore The Reproducibility Of Inflammatory Markers After Nasal Allergen Challenge In Subjects With Seasonal Allergic Rhinitis (Out Of Season) And The Effect Of A Single Dose Of Ibuprofen Or Fluticasone Propionate On The Allergen Response.
