Mean Weekly Total 4 Symptom Score (T4SS) During the Treatment Period
The T4SS is the sum of the symptom scores for sneezing, rhinorrhea, nasal pruritus and ocular pruritus. Each of the symptoms is rated retrospectively over the past 24 hours using a 4-point 0 to 3 scale (0 = absent, 1 = mild, 2 = moderate, 3 = severe). Total T4SS is the sum of the idividual scores and ranges from 0-12. Increasing values are associated with increasing severity of disease.
Time frame: During the treatment period until week 24
