Once-Daily Investigational Nasal Spray In Adults And Adolescents With Vasomotor Rhinitis

The TNSS was the sum of the individual symptom scores for rhinorrhoea, nasal congestion and post-nasal drip which was scored on a scale of 0-3 (total score 0-9). The severity of symptoms was defined as 0: none-symptom was not present, 1: mild-sign/symptom was clearly present but minimal awareness; easily tolerated, 2: moderate-definite awareness of sign/symptom that was bothersome but tolerable, 3: severe (sign/symptom was hard to tolerate; causes interference with activities of daily living and/or sleeping. The rTNSS was a rating of the severity of symptoms over the previous 12 hours and was performed in the morning (AM rTNSS) and evening (post meridian [PM] rTNSS). The daily rTNSS was the sum of two assessments. The Baseline daily rTNSS was defined as the average of the daily rTNSS over the 4 consecutive 24-hour periods prior to randomization, including the assessment on the morning of randomization. Change from Baseline was calculated as the on-treatment value minus the Baseline.

The morning pre-dose iTNSS was the sum of the individual symptom score for rhinorrhoea, nasal congestion and postnasal drip performed immediately prior to taking the daily dose which were scored on a scale of 0-3 (total score 0-9). The severity of symptoms was defined as 0: none-symptom was not present, 1: mild-sign/symptom was clearly present but minimal awareness; easily tolerated, 2: moderate-definite awareness of sign/symptom that was bothersome but tolerable, 3: severe (sign/symptom was hard to tolerate; causes interference with activities of daily living and/or sleeping. The Baseline daily iTNSS was defined as the average of the daily iTNSS over the 4 consecutive 24-hour periods prior to randomization, including the assessment on the morning of randomization. Change from Baseline was calculated as the on-treatment value minus the Baseline value.

Participants were evaluated effectiveness of study medication for relieving non-allergic rhinitis symptoms over the entire treatment period. The overall evaluation of response to therapy was based on a 7-point categorical scale (1-7) where the participants rate their perception of the change or lack of change in their VMR symptoms at the end of the study. The 7 categories were: 1: significantly improved, 2: moderately improved, 3: mildly improved, 4: no change, 5: mildly worse, 6: moderately worse and 7: significantly worse. Effectiveness of study medication for relieving VMR symptoms over the entire treatment period.
