Trial Outcomes & Findings for Study for the Treatment of Persistent Allergic Rhinitis With Desloratadine (Study P04684) (NCT NCT00405964)

NCT ID: NCT00405964

Last Updated: 2024-05-20

Results Overview

AM/PM PRIOR (the participant's status over previous 12 hours) T5SS from the participant's daily diary averaged over treatment Days 1 to 29. AM/PM is the average of separate morning (AM) and evening (PM) evaluations. Scores were defined for T5SS as 0: no symptoms to 15: all severe symptoms. A two-way analysis of variance (ANOVA) model with treatment and site effects was used to examine the treatment difference.

SECONDARY outcome

Timeframe: Baseline and Day 29

Population: All randomized participants

The RQLQ-S was only completed for participants above 18 years of age. The RQLQ-S was not available for participants 12 to 17 years of age. This questionnaire asked questions pertaining to daily activities, sleep, non-nose eye symptoms, practical problems, nasal symptoms, eye symptoms, and emotions. The scale went from 0 (not troubled) to 6 (extremely troubled). A two-way analysis of variance (ANOVA) model with treatment and site effects was used to examine the treatment difference.
