Primary

MeasureTime frameDescription
Mean Weekly Total 4 Symptom Score (T4SS) During the Treatment PeriodDuring the treatment period until week 24The 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.

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

Population: Only patients with a valid mean weekly T4SS during the treatment period were included in the analysis.

Mean Monthly Total 4 Symptom Score (T4SS) for Month 6 of 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 month 6 of the 6 months treatment period

Population: Only patients with a valid T4SS at month 6 were included in the analysis.

Mean Weekly Individual Symptoms Scores During the Treatment Period

Individual symptom scores include scores for Sneezing, Rhinorrhea, Nasal Pruritus, Ocular Pruritus, and Nasal Congestion. The subjects had to evaluate the severity of the symptoms retrospectively over the past 24 hours (0 = absent, 1 = mild, 2 = moderate, 3 = severe). Increasing scores are associated with increasing severity.

Time frame: During the treatment period until week 24

Population: 31 patients were included in the ITT-Set for each treatment group. Only patients with valid mean weekly individual symptoms scores were included in the analysis of this outcome measure. Number of patients analyzed are given for each individual symptoms score.
