Scientific title | An 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 acronym | NAC SMP-028 |
Study objectives | Primary: 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) studied | Allergic rhinitis |
Intervention | Subjects 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). |

Primary outcome measure | Pharmacodynamic 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. |
