Title: A Randomized, Double-blind, Double-dummy, Parallel-group, Placebo Controlled (on Inhaled Corticosteroid Medication), Multicenter Study to Evaluate the Efficacy and Safety of Vilanterol Inhalation Powder (GW642444) and Salmeterol, Compared With Placebo in the Treatment of Persistent Asthma in Adults and Adolescents Uncontrolled on Inhaled Corticosteroids
Brief Summary: The objective of this study is to evaluate the efficacy and safety of vilanterol inhalation powder administered once daily in the evening in adolescent and adult subjects 12 years of age and older with persistent asthma over a 12-week treatment period.


Options:
A: Inclusion Criteria:

1. Best pre-bronchodilator forced expiratory volume in 1 second (FEV1) of greater than 40% of their predicted normal value.
2. Patients must have a treatment regimen that includes a short-acting β2 agonist (SABA) (albuterol) for use as needed and either an inhaled corticosteroid (ICS) or an ICS/long-acting β2 agonist (LABA) as a preventative treatment for a minimum of 8 weeks before the SV. Patients currently taking low-dose ICS without LABA are not eligible for this study. Patients currently taking low-dose ICS/LABA may only be entered into the mid ICS strength. All patients must have been maintained on a stable dose of ICS or ICS/LABA for 4 weeks prior to the SV (or pre-SV if necessary) at 1 qualifying doses
3. To meet reversibility of disease criteria, the patient must demonstrate a ≥12% reversibility of FEV1 (and 200 mL for patients aged18 years and older) within 30 minutes following 4 inhalations of albuterol at the SV. Historic reversibility within the past 12 months of the SV may be used to meet this criterion.
4. Written informed consent/assent is obtained. For adult patients (aged 18 years and older, or as applicable per local regulations), the written informed consent form (ICF) must be signed and dated by the patient before conducting any study-related procedure. For minor patients (aged 12 to 17 years, or as applicable per local regulations), the written ICF must be signed and dated by the parent/legal guardian and the written assent form must be signed and dated by the patient (if applicable) before conducting any study-related procedure. Note: Age requirements are as specified by local regulations.
5. Outpatient \>= 12 years of age on the date of consent/assent. .
6. Asthma diagnosis: The patient has a diagnosis of asthma as defined by the National Institutes of Health (NIH). The asthma diagnosis has been present for a minimum of 3 months and has been stable (defined as no exacerbations and no changes in medication) for at least 30 days before providing informed consent.
7. The patient is able to perform acceptable and repeatable spirometry.
8. The patient is able to perform peak expiratory flow (PEF) with a handheld peak flow meter.
9. The patient is able to use a metered-dose inhaler (MDI) device without a spacer device and a MDPI device.
10. The patient is able to withhold (as judged by the investigator) his or her regimen of ICS or study drug, and rescue medication for at least 6 hours before the SV and before all treatment visits where spirometry is performed.
11. The patient/parent/legal guardian/caregiver is capable of understanding the requirements, risks, and benefits of study participation, and, as judged by the investigator, capable of giving informed consent/assent and being compliant with all study requirements.
12. SABAs: All patients must be able to replace their current SABA with albuterol/salbutamol HFA inhalation aerosol at the SV for use as needed for the duration of the study.
13. Female patients may not be pregnant, breastfeeding, or attempting to become pregnant.

Criteria for Randomization:

Patients were randomized into the study if they met all of the following criteria:

1. The patient continued to be in general good health, meeting the entry criteria.
2. The patient continued to have a predose/pre-albuterol FEV1 at the randomization visit (RV) that was ≥40% of predicted normal.
3. The patient had no clinically significant abnormal laboratory test results or ECG findings at the screening visit.
4. The patient had no significant changes in asthma medications during run-in, excluding the albuterol/salbutamol HFA (90 mcg ex actuator) or equivalent used as rescue medication as supplied per protocol.
5. The patient did not have a upper respiratory tract infection (URI) or lower respiratory tract infection (LRI) during the run in period. Patients who developed a URI or LRI during the run in period could be discontinued from the study and allowed to re-screen 2 weeks after resolution of symptoms.
6. The patient had no asthma exacerbation during the run in period, defined as any worsening of asthma requiring any significant treatment other than rescue albuterol/salbutamol HFA (90 mcg ex actuator) or equivalent or the patient's run-in MDPI. This included requiring the use of systemic corticosteroids and/or emergency department (ED) visit or hospitalization or an increase in the patient's regularly prescribed nonsteroidal maintenance treatment. Urgent care/ED visits where the treatment was limited to a single dose of nebulized albuterol/salbutamol did not meet the criteria of an asthma exacerbation.
7. The patient had no clinical visual evidence (on oropharyngeal examination) of oropharyngeal candidiasis.
8. The patient did not experience an adverse event that would result in failure to continue to meet selection criteria.
9. The patient did not use any of the prohibited concomitant medications during the run in period.
