Inclusion criteria

* The subject is healthy with the exception of seasonal allergic rhinitis. Healthy as determined by a responsible physician, based on a medical evaluation including history, physical examination, laboratory tests, cardiac monitoring. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator considers that the finding will not introduce additional risk factors and will not interfere with the study procedures. * Males and females who are aged between 18 and 65 years of age. A female is eligible to enter and participate in the study if she is of: 1. Non-childbearing potential (i.e., physiologically incapable of becoming pregnant), including any female who is post menopausal.

Weighted Mean Eye Symptom Score at 2-5 Hours Post-dose (1-4 Hours Post-start of Challenge)

The eye symptom score (total score of 0 \[none\] to 9 \[severe\]) was calculated as the sum of the symptom scores for watery eyes, itchy eyes, and red eyes, each of which was scored on a categorical scale from 0 to 3 (0=none, 1=mild, 2=moderate, 3=severe), and was measured at pre-challenge, and then every 15 minutes from 0.25 to 4 hours post-start of challenge chamber. Weighted mean eye symptom score was calculated by dividing the value of the area under the response time curve between 1 and 4 hours (calculated by trapezoidal rule) by the time interval of available data.

Time frame: Day 8 of each study period (Periods 1-4); up to Day 158

Weighted Mean Nasal Airflow at 2-5 Hours Post-dose (1-4 Hours Post-start of Challenge)

Allergic rhinitis decreases the passage of air through the nose (nasal airflow) by increasing the nasal airway resistance. Rhinomanometry is used as an objective measurement of airway resistance. Nasal airflow was measured using active anterior rhinomanometry at pre-challenge, and then every 30 minutes from 0.5 to 4 hours post start of VCC. Weighted mean nasal airflow was calculated by dividing the value of the area under the response time curve between 1 and 4 hours (calculated by trapezoidal rule) by the time interval of available data.
