Study Endpoints

Primary Endpoints

Minimum Cross-Sectional Area (Amin) Proportion Measured Using Acoustic Rhinometry
2 hrs 10 min, 2 hrs 25 min, 2 hrs 40 min post dose (Baseline); 2 hrs 55 min, 3 hrs 10 min, 3 hrs 25 min post dose on Day 1 of each intervention period

Acoustic rhinometry: a technique intended for assessment of the geometry of nasal cavity and nasopharynx and for evaluating nasal obstruction. At each time point, there were 2 acoustic rhinometry measurements taken, one for each nostril. Mean of the left and right nostril measurements was taken as measurement at each time point. Minimum Cross-Sectional Area (Amin) at Baseline was defined as mean of 3, 'post-diluent, pre-allergen challenge' measures for each intervention period at 2 hours (hrs) 10 minutes (min), 2 hrs 25 min and 2 hrs 40 min post PF-03654746/placebo dose. Amin 'post-allergen challenge' measures recorded at 2 hrs 55 min, 3 hrs 10 min and 3 hrs 25 min post PF-03654746/placebo dose for each intervention period was averaged to derive single 'post-allergen challenge' value. Amin proportion was defined as ratio of 'post-allergen challenge' value and 'Baseline/pre-allergen challenge value'. Diluent used was saline and allergen was short ragweed extract.
