Trial Outcomes & Findings for The Clinical Effects of Montelukast in Patients With Perennial Allergic Rhinitis (0476-265) (NCT NCT00092118)

NCT ID: NCT00092118

Last Updated: 2022-02-03

Results Overview

Mean change from baseline in Daytime Nasal Symptoms score averaged over the 6-week treatment period. The Daytime Nasal Symptoms score was calculated as the average of the 3 individual scores for Congestion, Rhinorrhea, and Sneezing, each rated by patients daily on a 4-point scale \[Score 0 (best) to 3 (worst)\].

Participant Flow

Patients were screened at 122 sites worldwide. Primary therapy period: Oct 2003 to May 2004

Patients who required excluded medication and those who did not meet a minimum predefined level of combined daytime nasal symptoms score during the run-in period were excluded from randomization.

PRIMARY outcome

Timeframe: 6 week treatment period (from baseline though the end of week 6)

Population: The primary efficacy analyses were performed using a modified intention-to-treat (MITT) approach. All patients with efficacy measurements, both at baseline and during the treatment period were included.

Mean change from baseline in Daytime Nasal Symptoms score averaged over the 6-week treatment period. The Daytime Nasal Symptoms score was calculated as the average of the 3 individual scores for Congestion, Rhinorrhea, and Sneezing, each rated by patients daily on a 4-point scale \[Score 0 (best) to 3 (worst)\].

SECONDARY outcome

Timeframe: At the end of the 6 week treatment period

Population: The analysis was performed using a modified intention-to-treat (MITT) approach. Patients were excluded if no treatment period data were available.

An evaluation by the patient, administered at the last visit (or upon discontinuation) using a 7-point scale \[Score 0 (best) to 6 (worst)\], in answer to a single question regarding the change in symptoms as compared to the beginning of the study.

SECONDARY outcome

Timeframe: Baseline and Week 6

Population: The primary efficacy analyses were performed using a modified intention-to-treat (MITT) approach. Patients were excluded if no baseline or treatment period data were available

Patients completed the validated, self-administered RQLQ which included 28 items on a 7-point scale \[Score 0 (best) to 6 (worst)\] across 7 domains: activities, sleep, nonnose/eye symptoms, practical problems, nasal symptoms, eye symptoms, and emotional. The scores for each domain were averaged, then scores for the 7 domains were averaged to obtain the overall score.
