NCT ID: NCT00666679

Last Updated: 2024-05-10

Results Overview

Participant Flow

Patients were recruited from 25 centers worldwide. Patient screening began 05-May-2008 and the first patient was randomized on 29-May-2008. The last patient's last visit was completed on 16-Feb-2009.

278 participants were screened; 144 were excluded. Randomized patients met the following criteria: FEV1 (Forced expiratory volume in one second) 50-80% predicted while withholding short-acting beta agonist (SABA) and reversibility of airway obstruction \>12% following SABA documented on at least two of the following visits: Visits 1, 2, and 3.

Montelukast + Mometasone Then Placebo + Mometasone
Patients were randomized to receive montelukast 1 mg (milligram) and open-label mometasone 220 mcg (micrograms) once daily by inhalation in the first intervention; and placebo for montelukast and open-label mometasone 220 mcg once daily by inhalation in the second intervention (after washout). During washout, patients received open-label inhaled mometasone 220 mcg and single-blind placebo for montelukast once daily by inhalation.
Placebo + Mometasone Then Montelukast + Mometasone
Patients were randomized to receive placebo for montelukast and open-label mometasone 220 mcg once daily by inhalation in the first intervention; and montelukast 1 mg and open-label mometasone 220 mcg once daily by inhalation in the second intervention (after washout). During washout, patients received open-label inhaled mometasone 220 mcg and single-blind placebo for montelukast once daily by inhalation.

PRIMARY outcome

Timeframe: Baseline and 2 weeks

Population: The analysis was based on the Full analysis set (FAS) population which included all randomized patients who took at least one dose of blinded post randomization study drug (inhaled montelukast or matching placebo) and had a measurement for analysis available in at least one treatment period of the cross-over design.

To determine the effect of 2 weeks of treatment with inhaled montelukast plus mometasone and mometasone alone on bronchodilation assessed by average change from baseline in FEV1 over the 2 week treatment period; measurements taken at 1 and 2 weeks contributed to the average.
