Design outcomes

Primary

Measure	Time frame
Main Objective: E.2.1 Main objective: To demonstrate that montelukast, compared with placebo, improves asthma control (as measured by the percentage of days without asthma ) over a 24-week treatment period in patients aged 6 months to 5 years with chronic asthma. To compare the safety profile of montelukast with placebo over the 24-week treatment period in patients aged 6 months to 5 years with chronic asthma.;Secondary Objective: E.2.2 Secondary objectives: To demonstrate that montelukast, compared with placebo, improves asthma control in patients aged 6 months to 5 years with chronic asthma over a 24-week treatment period as measured by: percentage of days without daytime symptoms; percentage of days without nighttime cough; percentage of days without ß-agonist use; percentage of patients without asthma attacks; percentage of patients without corticosteroid rescues.;Primary end point(s): Percentage of days without asthma (A day with all of the following: no daytime symptoms, no nighttime cough, no ß-agonist use, and no asthma attack (defined as a visit to a doctor, urgent care clinic, emergency room, or hospital for asthma [other than a scheduled visit to a doctor] or treatment with systemic or inhaled corticosteroid during the previous 24 hours)	—
