Trial Outcomes & Findings for Montelukast in Mild Asthmatic Children With Allergic Rhinitis (0476-367) (NCT NCT00442559)

NCT ID: NCT00442559

Last Updated: 2024-05-13

Results Overview

The score is an ordinal scale from 0 (no symptoms) to 5 (most symptoms). The change was calculated as the score at 12 weeks minus the score at baseline. Thus, a negative value for change from baseline indicates a favorable outcome.

Participant Flow

Conducted at 5 sites in Korea, Jan2005\~ Oct2007 in pediatric participants with comorbid mild asthma and allergic rhinitis. Participant's caregiver understands the study procedures and agrees to participate, signing the informed consent form.

Up to 1 week for wash-out - prior to baseline randomization.

Participant milestones
Measure
Montelukast
Participants were treated for 12 months after randomization: Participants 2 to 5 years of age took one 4 mg chewable tablet and 6 to 14 years of age took one 5 mg chewable tablet daily in the evening. If participants had exacerbated from mild to moderate within 12 weeks, inhaled corticosteroids (ICS) was added to Montelukast and ICS, respectively and those participants were excluded in the efficacy evaluation at 12 weeks.
Inhaled Corticosteroids (ICS)
Participants were treated for 12 months after randomization: Each participant's physician selected the ICS agent, dose, and regimen. If participants had exacerbated from mild to moderate within 12 weeks, ICS was added to Montelukast and ICS, respectively and those participants were excluded in the efficacy evaluation at 12 weeks.

PRIMARY outcome

Timeframe: Baseline and Week 12

Population: The primary efficacy parameter was a mean change from baseline to treatment for daytime asthma symptom score. Therefore 138 participants who didn't have a daytime asthma symptom score from the participant diary were not included.

The score is an ordinal scale from 0 (no symptoms) to 5 (most symptoms). The change was calculated as the score at 12 weeks minus the score at baseline. Thus, a negative value for change from baseline indicates a favorable outcome.

SECONDARY outcome

Timeframe: Baseline and Week 12

Population: The secondary efficacy parameter was a mean change from baseline to treatment for daily allergic rhinitis symptom score. Therefore 139 participants who didn't have a daily allergic rhinitis symptom score from the participant diary were not included.

The score is an ordinal scale from 0 (no symptoms) to 3 (most symptoms). The change was calculated as the score at 12 weeks minus the score at baseline. Thus, a negative value for change from baseline indicates a favorable outcome.
