Trial Outcomes & Findings for Montelukast in Exercise-Induced Bronchospasm - 2004 (0476-275) (NCT NCT00090142)

NCT ID: NCT00090142

Last Updated: 2022-02-02

Results Overview

In patients with EIB, the percent change from pre-exercise baseline FEV, to the lowest FEV1 within 60 minutes after exercise challenge (2 hours post-dose). The FEV1 measurement obtained 5 minutes before the exercise challenge was the baseline, and was specific to each exercise challenge.

Recruitment status

COMPLETED

Study phase

PHASE3

Target enrollment

62 participants

Primary outcome timeframe

Participant Flow

Patients were randomized at 8 sites (7 in the US and 1 in Peru). Primary therapy period: May to October 2004.

Patients who required excluded medications, or did not meet FEV1 criteria during the prestudy period were excluded from randomization. Patients who required a β-agonist after the exercise challenge and did not meet FEV1 criteria within 30 minutes of treatment were also excluded.

Montelukast 10 mg in Period I Then Placebo in Period II
A montelukast 10-mg tablet (Treatment Period I) was taken orally in the morning as a single witnessed dose. This was followed by a 3-7 day washout period and then a montelukast matching-image placebo tablet (Treatment Period II) was taken orally in the morning as a single witnessed dose.

PRIMARY outcome

Timeframe: Pre-exercise baseline measurement and 0-60 minutes after the exercise challenge performed 2 hours after a single oral dose

Population: The primary efficacy analysis used the modified intention-to-treat (MITT) approach. Patients with data from only one period were not included in the analysis.

In patients with EIB, the percent change from pre-exercise baseline FEV, to the lowest FEV1 within 60 minutes after exercise challenge (2 hours post-dose). The FEV1 measurement obtained 5 minutes before the exercise challenge was the baseline, and was specific to each exercise challenge.

SECONDARY outcome

Timeframe: Pre-exercise baseline measurement and 0-60 minutes after the exercise challenge performed at 2 hours postdose

Population: The secondary efficacy analysis used a MITT approach. If a patient received β-agonist rescue medication during the 60 minutes following exercise challenge, then the last pre-rescue FEV1 measurement was carried forward to 60 minutes. Patients with data from only one period were not included in the analysis.

The measure included only the area below the pre-exercise baseline.

Timeframe: Exercise challenge at 2 hours postdose

Population: The secondary efficacy analysis used a modified intention-to-treat (MITT) approach. Patients with data from only one period were not included in the analysis.

The time to recovery from maximum percent fall is the duration between the time at which the maximum percent fall in FEV1 after exercise challenge occurs and the time when FEV1 returns to within 5% of the preexercise baseline for the first time.
