Scientific titleAn exploratory, randomised, double-blind, placebo-controlled, 14-day, three-way crossover study, followed by an open label 1 day period when subjects will be dosed with intranasal fluticasone, nasal allergen challenge (NAC) study to evaluate the effects of SMP-028 on the release of inflammatory mediators after NAC with timothy grass pollen in subjects with allergic rhinitis out of season
Study acronymNAC SMP-028
Study objectivesPrimary:
To assess the pharmacodynamic (PD) response to a standardised nasal allergen challenge (NAC) with timothy grass pollen following multiple doses of SMP-028 in subjects with allergic rhinitis out of season.

Secondary:
1. To evaluate the effects of multiple doses of SMP-028 on allergic rhinitis symptoms after NAC
2. To evaluate the safety and tolerability of 14 days of dosing of SMP-028
3. To evaluate the multiple dose pharmacokinetics (PK) of SMP-028
Ethics approval(s)Added 21/05/10:
The Royal Free Hospital & Medical School Research Ethics Committee approved on the 17th of December 2009 (ref: D4050092 [NAC])
Health condition(s) or problem(s) studiedAllergic rhinitis
InterventionSubjects will be randomly assigned to one of two treatment groups. Within each group the subjects will receive two oral dosing regimens of SMP-028 and placebo.

Group A: SMP-028 40 mg once daily, SMP-028 160 mg once daily and placebo once daily
Group B: SMP-028 10 mg twice daily, SMP-028 80 mg twice daily and placebo twice daily
On Day 14: Only a single dose will be administered in the morning. Any remaining dose for that day will not be taken by the subject (e.g. Group B subjects).
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)SMP-028
Primary outcome measurePharmacodynamic endpoints:
1. Post-NAC nasal filter paper levels of chemical mediators and cytokines
2. Nasal lavage fluid eosinophil, neutrophil and monocyte counts (number/mm^3)

Clinical and PK endpoints:
3. Total nasal symptom score after NAC
4. Multiple dose PK of SMP-028

Safety endpoints:
5. Adverse events
6. Standard laboratory safety tests
7. Vital signs
8. Physical examinations
9. 12-lead electrocardiogram (ECG)
10. Hormone laboratory tests

All endpoints are followed up to day 14 apart from safety which will be followed up until 10 days +/- 3 days after the last treatment period.
