A 1-Year Safety Study of Medium and High Doses of Mometasone Furoate/Formoterol Combination Formulation and Medium and High Doses of Fluticasone/Salmeterol in Persistent Asthmatics Previously Treated With Medium to High Doses of Inhaled Glucocorticosteroids
A 1-Year Safety Study of Medium and High Doses of Mometasone Furoate/Formoterol Combination Formulation and Medium and High Doses of Fluticasone/Salmeterol in Persistent Asthmatics Previously Treated With Medium to High Doses of Inhaled Glucocorticosteroids
The purpose of this study is to evaluate the long-term safety of mometasone furoate/formoterol (MF/F) metered dose inhaler (MDI) 200/10 mcg twice-a-day (BID) and MF/F MDI 400/10 mcg BID and two doses of fluticasone/salmeterol combination (F/SC) (250/50 mcg BID and 500/50 mcg BID) in subjects with persistent asthma who require maintenance treatment on inhaled glucocorticosteroids (ICS); evaluator-blind.
In addition, the extrapulmonary effects on 24-hour plasma cortisol area under curve (AUC), of MF/F MDI 200/10 mcg BID, MF/F MDI 400/10 mcg BID, F/SC MDI 250/50 mcg BID, and F/SC MDI 500/50 mcg BID will be evaluated.
Inclusion Criteria:
Subjects of either sex and any race, at least 12 years of age, with a diagnosis of asthma of at least 12 months.
Use of medium or high daily dose of ICS (alone or in combination with long-acting beta-agonist [LABA]) for at least 12 weeks prior to Screening and have been on a stable regimen for at least 2 weeks prior to Screening.
Medium daily doses of ICS:
High daily doses of ICS:
If there is no inherent harm in changing the subject's current asthma therapy, the subject must discontinue prescribed ICS or ICS/LABA combination at Baseline.
Must show evidence of reversibility within the last 12 months or during the Screening Period. Historical reversibility defined as an increase in absolute forced expiratory volume in 1 second (FEV1) of >= 12% and >= 200 mL will qualify if performed within 12 months of Screening. If no historical reversibility, subject must demonstrate an absolute FEV1 of >= 12% and >= 200 mL within 10 to 15 minutes after four puffs of salbutamol at Visit 1 or anytime prior to Baseline.
At Screening and Baseline, FEV1 must be >= 50% predicted, when restricted medications are withheld for the appropriate intervals.
Complete blood count, blood chemistries, urinalysis, and electrocardiogram (ECG) conducted at Screening must be within normal limits or clinically acceptable to the investigator/sponsor. A chest x-ray performed at Screening or within 12 months prior must be clinically acceptable.
A female of childbearing potential must be using a medically acceptable, adequate form of birth control:
Birth control must have started at least 3 months prior to Screening. Subject must agree to continue its use for the duration of the study. A subject of childbearing potential who is not currently sexually active must agree to use a medically acceptable method should she become sexually active during the study. Women who have been surgically sterilized or are at least 1 year postmenopausal are not considered to be of childbearing potential. A subject of childbearing potential must have a negative serum pregnancy test at Screening.
