- To assess the change in daily Total Nasal Symptom Score (TNSS) between Rhinix™ and placebo [ Time Frame: 11.00-17.00 with recordings at 30. minute increments. ]
Baseline recording at 09.00 Run-in recordings from 09.30-11.00 Daily Total Nasal Symptom Score evaluated from 11.00-17.00 with the last recording at 17.00, recordings at 30 minute increments.
Total Nasal Symptom Score is the sum of 4 symptoms (runny nose, blocked nose, itchy nose and sneezing) which are each evaluated on a scale of 0=none, 1=mild, 2=moderate, 3=severe symptoms
- To assess the change in Daily Throat Irritation between Rhinix™ and placebo [ Time Frame: 11.00-17.00 with hourly increments ]
Baseline recording at 09.00 Run-in recording at. 10.00 Daily Throat Irritation evaluated from 11.00-17.00 with the last recording at 17.00, recordings at hourly increments.
Daily Throat Irritation is the sum of 6 symptom ratings on a Visual Analogue Scale.
- To assess the correlation between maximum TNSS and difference in Daily TNSS [ Time Frame: 11.00-17.00 at 30 minute increments ]
Daily TNSS is described in the Primary Efficacy Endpoint. Maximum TNSS is the single highest TNSS between 11.00 and 17.00
The correlation will be graphically shown using a Bland-Altman plot.
- Change in Daily TNSS for subgroup [ Time Frame: 11.00-17.00 at 30 minute increments ]
Subgroup analysis of change in daily TNSS between RHINIX and placebo for the subjects with at least one rating of TNSS ≥ 6 on at least one of the two study days.
