Brief summary:
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.

Detailed description:

Arms:
arm 1: Participants received a single dose of each treatment in the following order, separated by a washout period of 6-7 days: Period 1: Formoterol fumarate 12 μg via pMDI + placebo to formoterol fumarate via DPI; Period 2: Placebo to formoterol fumarate / mometasone furoate via pMDI + placebo to formoterol fumarate via DPI; Period 3: Placebo to formoterol fumarate / mometasone furoate via pMDI + formoterol fumarate via DPI; Period 4: Formoterol fumarate / mometasone furoate 10 μg / 100 μg via pMDI + placebo to formoterol fumarate via DPI. Participants were allowed to continue their regular asthma maintenance inhaled corticosteroid medication throughout the study and were supplied with the short-acting β2-agonist (SABA) salbutamol as rescue medication. arm 2: Participants received a single dose of each treatment in the following order, separated by a washout period of 6-7 days: Period 1: Placebo to formoterol fumarate / mometasone furoate via pMDI + formoterol fumarate via DPI; Period 2: Formoterol fumarate 12 μg via pMDI + placebo to formoterol fumarate via DPI; Period 3: Formoterol fumarate / mometasone furoate 10 μg / 100 μg via pMDI + placebo to formoterol fumarate via DPI; Period 4: Placebo to formoterol fumarate / mometasone furoate via pMDI + placebo to formoterol fumarate via DPI. Participants were allowed to continue their regular asthma maintenance inhaled corticosteroid medication throughout the study and were supplied with the short-acting β2-agonist (SABA) salbutamol as rescue medication. arm 3: Participants received a single dose of each treatment in the following order, separated by a washout period of 6-7 days: Period 1: Formoterol fumarate / mometasone furoate 10 μg / 100 μg via pMDI + placebo to formoterol fumarate via DPI; Period 2: Placebo to formoterol fumarate / mometasone furoate via pMDI + formoterol fumarate via DPI; Period 3: Placebo to formoterol fumarate / mometasone furoate via pMDI + placebo to formoterol fumarate via DPI; Period 4: Formoterol fumarate 12 μg via pMDI + placebo to formoterol fumarate via DPI. Participants were allowed to continue their regular asthma maintenance inhaled corticosteroid medication throughout the study and were supplied with the short-acting β2-agonist (SABA) salbutamol as rescue medication. arm 4: Participants received a single dose of each treatment in the following order, separated by a washout period of 6-7 days: Period 1: Placebo to formoterol fumarate / mometasone furoate via pMDI + placebo to formoterol fumarate via DPI; Period 2: Formoterol fumarate / mometasone furoate 10 μg / 100 μg via pMDI + placebo to formoterol fumarate via DPI; Period 3: Formoterol fumarate 12 μg via pMDI + placebo to formoterol fumarate via DPI; Period 4: Placebo to formoterol fumarate / mometasone furoate via pMDI + formoterol fumarate via DPI. Participants were allowed to continue their regular asthma maintenance inhaled corticosteroid medication throughout the study and were supplied with the short-acting β2-agonist (SABA) salbutamol as rescue medication.

Interventions: intervention 1: Mometasone furoate/formoterol fumarate (MFF) intervention 2: Formoterol fumarate 12 μg pMDI (F12M) intervention 3: Formoterol fumarate 12 μg DPI (F12D) intervention 4: Placebo to F12D intervention 5: Placebo to F12M/MFF
Intervention descriptions: intervention 1: Formoterol fumarate dihydrate / mometasone furoate combination product 10 μg / 100 μg delivered via Pressurized Metered Dose Inhaler (pMDI). One dose consisted of 2 puffs x 5 μg / 50 μg. intervention 2: Formoterol fumarate dihydrate 12 μg delivered via Pressurized Metered Dose Inhaler (pMDI) (1 dose = 2 puffs x 6 μg). intervention 3: Formoterol fumarate dihydrate 12 μg delivered via Dry Powder Inhaler (DPI). intervention 4: Placebo to formoterol fumarate DPI delivered via DPI intervention 5: Placebo to formoterol fumarate pMDI and formoterol fumarate / mometasone furoate delivered via pMDI
