Trial Outcomes & Findings for A Study to Assess Intranasal Repeat Dose Effect of Levocabastine in the Subjects With Allergic Rhinitis (NCT NCT01949051)

NCT ID: NCT01949051

Last Updated: 2017-06-06

Results Overview

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.

Measure
Placebo/Levocabastine
n=78 Participants
Participants received placebo/ Levo at a dose of 200 µg OD in the morning as 2 nasal sprays (50 µg per spray) into each nostril or 400 µg BID in the morning and evening as 2 nasal sprays (50 µg per spray) into each nostril for 7 days each, in a crossover design. Treatment was given in one of six sequences in Periods 1, 2, and 3, (14 to 20 day washout period between treatments): ABC, BCA, CAB, ACB, BAC, CBA (A, Levo 200µg; B, Levo 400µg: C, Placebo). On Day 8 of each treatment period (approximately 12 hours post dosing for treatment A and 24 hours post dosing for treatment B and C), participants entered the environmental exposure chamber (EEC) for a 4-hour period, and the assessments were conducted 12-24 hours post-dose. All participants attended a follow-up visit within 7 to 14 day after their final dose, and the overall duration for participation in the study (screening to follow-up) was 13 weeks.

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.

SECONDARY outcome

Timeframe: Day 8 of each treatment period (up to 13 Weeks)

Population: ITT Population. Only those participants contributing data at the indicated time points were analyzed.

TNSS contains symtom scores for the four individual components (nasal congestion \[NACG\], rhinorrhea \[RHSCR\], nasal itching \[NAITS\] and sneezing \[SNZS\]), each scored on a 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 is administered in a sealed chamber to evaluate the efficacy of antihistamines/other treatments. The participants recorded their symptom scores on an e-diary. The mean score for each participant was calculated using the available diary data from the assessment periods, taking the average of non-missing data during the period. Weighted mean of the individual symptoms of theTNSS were 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.
