Single Dose Study of the Effect of Formoterol Fumarate in Combination With Mometasone Furoate Inhaled Via a Pressurized Metered Dose Inhaler (pMDI) in Children Aged 5-11 Years Old With Persistent Asthma

A Randomized, Double-blind, Double-dummy, Multi-centre, 4-way Cross-over Study to Compare the Single Dose Bronchodilatory Effect of Formoterol Fumarate in Combination With Mometasone Furoate Delivered Via Pressurized Metered Dose Inhaler (pMDI) to Placebo Delivered Via pMDI in Children Aged 5-11 Years Old With Persistent Asthma

This study is being conducted to compare the pharmacodynamics (bronchodilation, onset and duration of action), of a single dose of formoterol fumarate in combination with mometasone furoate to placebo in children of 5-11 years with persistent asthma. The study will also assess the bronchodilatory effect of a single dose of formoterol fumarate alone and in combination with mometasone furoate delivered via a pressurized metered dose inhaler (pMDI) to the bronchodilatory effect of formoterol fumarate delivered via a dry powder inhaler (DPI). Furthermore, pharmacokinetic assessments of plasma and urine will also be conducted throughout the study to assess systemic exposure following administration of the study medication.

Inclusion Criteria:

• 5 to 11 years of age of either sex and of any race
• A diagnosis (according to the Global Initiative for Asthma [GINA] guidelines) of persistent asthma for a period of at least 6 months prior to screening and must have been on a stable asthma regimen (daily dose unchanged) for at least 4 weeks prior to screening
• β2-agonist reversibility, defined as an increase in absolute FEV1 of ≥12% within 30 minutes after administration of 200μg of salbutamol without the use of a spacer or its equivalent in accordance with ATS/ERS standards
• A child must have an FEV1 of ≥ 60% and ≤ 90% of Polgar predicted when all restricted medications have been withheld for the appropriate intervals

Exclusion Criteria:

• Use of other investigational drugs at the time of enrolment, or within 30 days or 5 half-lives of enrolment, whichever is longer.
• History of malignancy of any organ system within past 5 years.
• Pre-dose change (increase or decrease) in absolute FEV1 of 15% at Visit 2, compared with value at screening.
• Hospitalized or had an emergency room treatment for an acute asthma exacerbation in the 1 month prior to Visit 1, or who had a clinical deterioration of asthma between Visits 1 and 2 that resulted in emergency treatment, hospitalization, or treatment with excluded asthma medication.
• Significant medication condition or situation.
• QTc > 440 msec (boys) or > 450 msec (girls) on electrocardiogram(ECG) assessment at screening.
• Upper or lower respiratory tract infection within 4 weeks prior to screening.
• Chronic conditions affecting the respiratory tract or chronic lung diseases.
