| NCT01949051 | A Study to Assess Intranasal Repeat Dose Effect of Levocabastine in the Subjects With Allergic Rhinitis | PHASE2 | COMPLETED | 78 | — | — | Oct 1, 2013 | Feb 4, 2014 | Jun 6, 2017 | 1 | Canada |
The TNSS (score of 0-12) is defined as the sum of the symptom scores for the four individual components (nasal congestion, rhinorrhea, nasal itch, and sneezing, each scored on 0-3 scale \[0=none, 1=mild, 2=moderate, 3=severe\]). TNSS was measured at the pre-allergen chamber challenge, and then every 15 minutes from 0 to 4 hours post start of the allergen chamber challenge. In the Environmental Exposure Chamber (EEC), aerosolized allergen was administered in a sealed chamber to evaluate the efficacy of antihistamines/other treatments. Weighted mean TNSS was calculated by dividing the value of the area under the response time curve over the 0-4 hours (calculated by trapezoidal rule) by the time interval of available data.
