Primary Outcome Measures
NameTimeMethod
Change in the total nasal symptom score (TNSS) during the total treatment period from the baselineFrom Baseline to Day 14

TNSS is a sum of the nasal symptom score for sneezing, rhinorrhea, nasal congestion, and nasal itching. Each symptom is scored on a scale from 0 to 3; the range of sums for TNSS is 0 to 12. The symptoms were evaluated using a scale of 0, 1, 2, or 3; a larger score indicates more severe symptoms. The Baseline value is defined as the average TNSS over the last 3 consecutive days prior to Day 1. For total treatment period, the average TNSS for each participant was calculated using available diary data from the total treatment period, taking the average of non-missing data during the period. Change from Baseline was calculated as the score at Baseline minus the mean score for the total treatment period.

Secondary Outcome Measures
NameTimeMethod
Changes in TNSS on the first and the second weeks of the treatment period from the baselineFrom Baseline to Day 7 and Day 14

TNSS is a sum of the nasal symptom score for sneezing, rhinorrhea, nasal congestion, and nasal itching. Each symptom is scored on a scale from 0 to 3; the range of sums for TNSS is 0 to 12. The symptoms were evaluated using a scale of 0, 1, 2, or 3; a larger score indicates more severe symptoms. The Baseline value is defined as the average TNSS over the last 3 consecutive days prior to Day 1. For total treatment period, the average TNSS for each participant was calculated using available diary data from the total treatment period, taking the average of non-missing data during the period. Change from Baseline was calculated as the score at Baseline minus the mean score at Week 1 and Week 2.

Investigator global improvement rating on the first day of Treatment Week 2 (Day 8) and the final observation day (Day 15 ) or at discontinuation (DC)Day 8 and Day 15 or DC

The investigator evaluated the participant's improvement rating (defined as improvement in the symptoms of rhinitis compared with Baseline), using the following 5 categories: significantly improved, moderately improved, mildly improved, unchanged, and worsened.

Time-course changes in a total of daily mean nasal symptom scores (TDNSS)From Baseline to Day 14

TDNSS is a sum of the daily nasal symptom score for sneezing, rhinorrhea, nasal congestion, and nasal itching. Each symptom is score on a scale from 0 to 3; the range of sums for TDNSS is 0 to 12; a larger score indicates more severe symptoms.

Mean scores for each nasal symptom and the time-course changes for the scoresFrom Baseline to Day 14

Each nasal symptom score for sneezing, rhinorrhea, nasal congestion and nasal itching is scored on a scale from 0 to 3; the larger score indicates more severe symptoms. The parent/guardian or the participant scored nasal symptoms every day.

Participant global improvement rating on the first day of Treatment Week 2 (Day 8) and the final observation day (Day 15) or at DCDay 8 and Day 15 or DC

The participant's parent/guardian or the participant evaluated the participant's improvement rating (defined as improvement in the symptoms of rhinitis compared with Baseline), using the following 7 categories: significantly improved, improved, slightly improved, unchanged, slightly worsened, worsened, and significantly worsened.

Changes in each rhinoscopy finding (swelling and color of inferior conchal mucosa and aqueous secretion volume (ASV)) on first day of Treatment Week 1 (Day 1), the first day of Treatment Week 2 (Day 8) and the final observation day (Day 15) or at DCDay 1, Day 8 and Day 15 or DC

Rhinoscopy was assessed by the investigator by scoring swelling of inferior conchal mucosa scored as 0 (none), 1 (possible to see center of the middle turbinate), 2 (between 1 and 3), or 3 (impossible to see middle turbinate); color of inferior conchal mucosa scored as 0 (normal), 1 (pink), 2 (red), or 3 (pale); aqueous secretion volume (vol) scored as 0 (none), 1 (small amount adhered), 2 (between 1 and 3), or 3 (filled).
