Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Allocation to one of three nasal sprays. Twice daily application (one spray per nostril) for 7 days.

The nasal sprays include:
(A) an intranasal antihistamine (Azep; Azelastine hydrochloride 125 mcg/spray)
(B) an intranasal steriod (Flixonase; Fluticasone proprionate 50mcg/spray)
(C) an intranasal antihistamine and steriod combination (Dymista: Azelastine hydrochloride and Fluticasone proprionate 125/50 mcg per spray).

Compliance will be monitored with return and weighing of spray bottle and self-report in daily symptom and medication diaries

Outcomes
Primary outcome [1] 299870 0
Gene expression profiles in nasal mucosal cells following nasal spray administration. This will be assessed using the Nanostring ncounter platform using the PanCancer immune profiling kit (770 genes involved in immune and inflammatory pathways).
Timepoint [1] 299870 0
The intervention period is 7 days. Primary endpoints will be determined prior to administration at baseline (day 0) and at the end of treatment (day 7).
Secondary outcome [1] 328344 0
Gene expression profiles in blood following nasal spray administration.. This will be assessed using the Nanostring ncounter platform using the PanCancer immune profiling kit (770 genes involved in immune and inflammatory pathways).
Timepoint [1] 328344 0
The intervention period is 7 days. Primary endpoints will be determined prior to administration at baseline (day 0) and at the end of treatment (day 7).

Stratified allocation based on sensitivity to allergens (dust mite only vs dustmite and grass allergy), gender and age. Simple randomisation table - computer software
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
