Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Average Rhinoconjunctivitis Total Symptom Score (ARTSS)
Time Frame: Pollen period (average of 38.6 days)

Average Rhinoconjunctivitis Total Symptom Score during the pollen period while participant on treatment.

Participants assessed daily, during the pollen period, 6 rhinoconjunctivitis symptoms (sneezing, rhinorrhea, nasal pruritus, nasal congestion, ocular pruritus and watery eyes) each symptom is scored as follows: 0: no symptoms, 1: mild symptoms, 2: moderate symptoms, 3: severe symptoms. The sum of the 6 symptoms is the Rhinoconjunctivitis Total Symptom Score (RTSS) (range 0-18). The lower the score, the better the outcome.
