A Randomized, Double-Blind, Placebo-Controlled, Parallel Group, Multicenter Study to Evaluate the Efficacy and Safety of GW685698X 200mcg Twice Daily, GW685698X 200mcg and 400mcg Once Daily in the Morning, and GW685698X 200mcg and 400mcg Once Daily in the Evening Compared with Placebo for 8 Weeks in Adolescent and Adult Subjects (12 Years of Age and Older) with Persistent Asthma.
|Ages Eligible for Study:
||12 Years and older (Child, Adult, Senior)
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- History of Life-Threatening Asthma: History of life-threatening asthma, defined as an asthma episode that required intubation and/or was associated with hypercapnia, respiratory arrest or hypoxic seizures.
- Anti-Asthma Medications: Asthma medications listed below must not have been used prior to Visit 1 for the required interval listed below, and not taken during the study: Within 24 hours of Visit 1: Oral short-acting beta2-agonists: Within 2 weeks of Visit 1:Combination therapy containing inhaled beta2-agonists and ICS for asthma (e.g., fluticasone propionate/salmeterol combination, budesonide/formoterol combination);Slow-release bronchodilators (e.g., aminophylline, theophylline);Anticholinergics; Long-acting beta2-agonists (e.g., salmeterol); Ketotifen; Nedocromil sodium; Sodium cromoglycate; Oral long-acting beta2-agonists. Within 4 weeks of Visit 1: Anti-leukotrienes including suppressors of leukotriene production and antagonists. Within 12 weeks of Visit 1: Systemic, oral, parenteral, or depot corticosteroids; Anti-IgE (e.g., omalizumab).
- Other Medications: The medications listed below must not have been used prior to Visit 1 for the required interval indicated below, and not taken during the study: Within 4 weeks of Visit 1: Known potent inhibitors of CYP3A4 (e.g., ritonavir, ketoconazole)
- Respiratory Infection: History of a respiratory tract infection within 4 weeks of Visit 1. In addition, the subject must be excluded, if such infection occurs between Visits 1 and 2.
- Asthma Exacerbation: History of a an asthma exacerbation within 4 weeks of Visit 1, any asthma exacerbation requiring oral corticosteroids within 3 months of Visit 1, or any hospitalization due to asthma exacerbation within 6 months of Visit 1.
- Investigational Medications: A subject must not have used any investigational drug within 30 days prior to Visit 1 or within ten half-lives (t1/2) of the prior investigational study (which ever is longer of the two) or concurrently during the study.
- Concurrent Diseases/Abnormalities: Historical or current evidence of clinically significant uncontrolled disease including, but not limited to: cardiovascular disease, malignancy, hepatic disease, renal disease, hematological disease, neurological disease, or pulmonary disease (including, but not confined to chronic bronchitis, emphysema, bronchiectasis with the need of treatment, cystic fibrosis, bronchopulmonary dysplasia, and chronic obstructive pulmonary disease). Significant is defined as any disease that, in the opinion of the investigator, would put the safety of the subject at risk through participation, or which would affect the efficacy or safety analysis if the disease/condition exacerbated during the study.
- Oropharyngeal Examination: A subject will not be eligible for the run-in if he/she has evidence of oropharyngeal candidiasis at Visit 1.
- Drug Allergy: Any adverse reaction including immediate or delayed hypersensitivity to any beta2-agonist, sympathomimetic drug, or any intranasal, inhaled, or systemic corticosteroid therapy.
- Milk Protein Allergy: History of severe milk protein allergy.
- Immunosuppressive Medications: A subject must not be using, or require use of, immunosuppressive medications during the study.
Note: Immunotherapy for the treatment of allergies is allowed during the study provided that it was initiated prior to Visit 1 and the subject is maintained on a stable daily dose throughout the study period.
- Attendance: A subject will not be eligible if he/she or his/her parent or legal guardian has any infirmity, disability, or geographical location which seems likely (in the opinion of the Investigator) to impair compliance with any aspect of this study protocol or scheduled visits to the study center and compliance with study medication or procedures (e.g., completion of daily diary). Neurological or psychiatric disease or history of drug or alcohol abuse which would interfere with the subject's proper completion of the protocol requirements excludes study participation.
- Tobacco Use: A subject may not have used tobacco products within the past one year (i.e., cigarettes, cigars, or pipe tobacco) and must not have historical use of >10 pack years (e.g., 20 cigarettes/day for 10 years).
- Affiliation with Investigator's Site: A subject will not be eligible for this study if he/she is an immediate family member of the participating investigator, sub-investigator, study coordinator, or employee of the participating investigator.
