MeasureTime frame
Secondary Objective: - To evaluate the effects of multiple oral doses of S-555739 100 mg once daily on allergen challenge induced total nasal airway resistance (NAR) between active and placebo treatments at Day 9 - To evaluate the effects of multiple oral doses of S-555739 100 mg once daily on nasal peak inspiratory flow, internal nasal luminal volume and minimum cross sectional area between active and placebo treatments - To evaluate the effects of multiple oral doses of S-555739 100 mg once daily on nasal symptoms of allergic rhinitis between active and placebo treatments. - To evaluate the general safety and tolerability of multiple oral doses of S-555739 100 mg once daily. ;Main Objective: To evaluate the effects of multiple oral doses of S-555739 100 mg once daily on allergen challenge induced total nasal airway resistance (NAR) between active and placebo treatments at Day 7.;Primary end point(s): The primary endpoint is the change in total Nasal Airways Resistance (NAR) after PD100 challenge at Day 7 on active and placebo treatments.
