General information about the trial
|
|||
Main objective of the trial |
This study will see if there is a change in breathing after exercising when the child receives study drug (montelukast or placebo). Breathing will be measured by a spirometer before exercising and measured again several times after exercising.
|
||
Protection of trial subjects |
This study was conducted in conformance with Good Clinical Practice standards and applicable country and/or local statutes and regulations regarding ethical committee review, informed consent, and the protection of human subjects participating in biomedical research.
The following additional measure defined for this individual study was in place for the protection of trial subjects: rescue with inhaled short-acting beta-agonist.

In Period 1 (screening period/ placebo run-in), participants received a single-blind dose of matching-image placebo. In Period 2, participants 4-5 years of age were randomized to receive one montelukast 4-mg chewable tablet (single dose). Period 3 was the crossover to one matching placebo 4-mg chewable tablet (single dose) after a 3- to 7-day washout period. No participants 4-5 years of age were randomized, so the 4-mg doses were not dispensed. Participants 6-14 years of age were randomized to receive one montelukast 5-mg chewable tablet (single dose) in Period 2, crossing over to one matching placebo 5-mg chewable tablet (single dose) in Period 3 after a 3- to 7-day washout period. | ||||||||||||||||||

Maximum Percent Fall in FEV1 After Exercise Challenge at 2 Hours Postdose | ||||||||||||
End point description |
Maximum Percent Fall in FEV1 was defined as the % change from pre-exercise baseline FEV1 to the lowest FEV1 within 60 mins (minutes) after exercise. Spirometry measurements were taken 5 mins prior to each exercise challenge and immediately, 5, 10, 15, 30, 45, & 60 mins after each exercise challenge. The 2-hour exercise challenges occurred 2 hours after the witnessed dose of study medication. The calculation used to produce the results was [100*(1-(X/Y))] where X= the lowest FEV1 within 60 mins after exercise & Y= pre-exercise baseline FEV1. Smaller values mean greater response to therapy. The analysis of efficacy data was carried out using a completers analysis population. This population included all randomized participants who received the witnessed dose of study drug in both active treatment periods, had at least one post-exercise FEV1 measurement in both active treatment periods, and had to have a baseline pre-exercise challenge FEV1.

Area Under the Curve for FEV1 percent fall from pre-exercise baseline to 60 minutes following exercise challenge (AUC0-60 min) at 2 hours post-dose | ||||||||||||
End point description |
AUC0-60min was defined as the Area Under the Curve for FEV1 percent change from pre-exercise baseline to the 60 mins following exercise challenge. The area was computed by applying the trapezoidal rule, and including only the area below the pre-exercise baseline. If a participant received β-agonist during the 60 mins after the exercise challenge, the FEV1 measurements obtained after β-agonist administration were excluded and the last pre-rescue FEV1 measurement was carried forward to the 60 mins time point in the calculation of the AUC0-60 min. Smaller values mean greater response to therapy. The analysis of efficacy data was carried out using a completers analysis population. This population included all randomized participants who received the witnessed dose of study drug in both active treatment periods, had at least one post-exercise FEV1 measurement in both active treatment periods, and had to have a baseline pre-exercise challenge FEV1.

Area Under the Curve for FEV1 percent fall from pre-exercise baseline to 60 minutes following exercise challenge (AUC0-60 min) at 24 hours post-dose | ||||||||||||
End point description |
AUC0-60min was defined as the Area Under the Curve for FEV1 percent change from pre-exercise baseline to the 60 mins following exercise challenge. The area was computed by applying the trapezoidal rule, and including only the area below the pre-exercise baseline. If a participant received β-agonist during the 60 mins after the exercise challenge, the FEV1 measurements obtained after β-agonist administration were excluded and the last pre-rescue FEV1 measurement was carried forward to the 60 mins time point in the calculation of the AUC0-60 min. Smaller values mean greater response to therapy. The analysis of efficacy data was carried out using a completers analysis population. This population included all randomized participants who received the witnessed dose of study drug in both active treatment periods, had at least one post-exercise FEV1 measurement in both active treatment periods, and had to have a baseline pre-exercise challenge FEV1.

Time to recovery from Maximum Percent Fall in FEV1 at 2 hours post-dose | ||||||||||||
End point description |
This endpoint was defined as the duration between the time at which the maximum percent fall in FEV1 occurred & the time when the percent fall in FEV1 returned to within 5% of the pre-exercise baseline for the first time. Spirometry measurements were taken 5 mins prior to each exercise challenge & immediately, 5, 10, 15, 30, 45, & 60 mins after each exercise challenge. If participant had not returned to within 5% of the pre-exercise FEV1 value by 60 mins, then measurements were obtained at 75 & 90 mins. The 2-hour exercise challenges occurred 2 hours after the witnessed dose of medication. The analysis of efficacy data was carried out using a completers analysis population. This population included all randomized participants who received the witnessed dose of study drug in both active treatment periods, had at least one post-exercise FEV1 measurement in both active treatment periods, and had to have a baseline pre-exercise challenge FEV1.

Reporting group description |
In Period 1 (screening period/ placebo run-in) participants received a single-blind dose of matching-image placebo. Participants 6-14 years of age were randomized to receive one montelukast 5-mg chewable tablet (single dose) in Period 2 or Period 3, according to the randomized treatment sequence assigned.
