A Double Blind Open Label Comparator Study to Compare Treatments in 4 to 11 Year Old Patients With Asthma

Inclusion Criteria:

- The patient is a male or female aged 4 through 11 years of age, inclusive

- Severity of disease: The patient has persistent asthma

- Asthma diagnosis: The patient has a diagnosis of asthma as defined by the NIH.

- The patient has required less than 4 inhalations per week of rescue bronchodilator
(on average) for the 4 weeks preceding the SV.

- The patient is able to withhold (as judged by the investigator) his or her rescue
medication for at least 6 hours before the SV and before all treatment visits.

- The patient must have a weight of 18 kg or higher.

- Additional criteria apply, please contact the investigator for more information.

Exclusion Criteria:

- The patient has a history of a life-threatening asthma exacerbation that is defined
for this protocol as an asthma episode that required intubation and/or was associated
with hypercapnia, respiratory arrest, or hypoxic seizures.

have a negative serum pregnancy test at the SV. Eligible menstruating female patients
unwilling to employ appropriate birth control measures to ensure pregnancy will be
excluded

- The patient has participated as a randomized patient in any investigational drug
study within 30 days (starting from the final follow-up visit of that study)
preceding the SV or plans to participate in another investigational drug study at any
time during this study.

- The patient has a known hypersensitivity to any corticosteroid, salmeterol, or any of
the excipients in the study drug (ie, lactose).

- The patient has a culture-documented or suspected bacterial or viral upper
respiratory tract infection (URTI) or lower respiratory tract infection (LRTI),

- Patients who have donated whole blood 60 days before the first dose, or receive or
donate plasma, white blood cells, or platelets within the 14 days before the first
dose or study drug, and for 90 days after last dose of study drug.

- The patient has a disease/condition that in the medical judgment of the investigator
would put the safety of the patient at risk through participation or that could
affect the efficacy or safety analysis if the disease/condition worsened during the
