This purpose of this study is to show the superiority and long term safety and efficacy of
adding a long acting beta agonist (salmeterol) to constant dose of an inhaled corticosteroid
(fluticasone propionate) in symptomatic subjects with asthma. The 12-month assessment of
asthma control will provide key information on the efficacy and safety of the combination
therapy. The safety measure will be an assessment of adverse events

1. Age: A subject must be 12 years of age at Visit 1 (screening).
2. Asthma Diagnosis: A documented diagnosis of persistent asthma, for at least
six months, as defined by the following American Thoracic Society
definition:
Asthma is a clinical syndrome characterized by increased responsiveness of the airways
to a variety of stimuli. The major symptoms of asthma are episodes of dyspnea,
wheezing, and cough, which may vary from mild and almost undetectable to severe and
unremitting (status asthmaticus). The primary physiological manifestation of this
hyperresponsiveness is variable airway obstruction. This can take the form of
spontaneous fluctuations in the severity of obstruction, substantial improvements in
the severity of obstruction following bronchodilators or corticosteroids, or increased
obstruction caused by drugs or other stimuli [American Thoracic Society, 1987].
1. Asthma Medication History: A subject must be using a low to medium dose of an
ICS (Table 1) OR a combination of controller medications (Table 2), containing a
low (total daily) dose ICS (as defined in Table 1) for at least 4 weeks preceding
screening.
Table 1 (ICS Dosage Table) Inhaled Corticosteroid (Dosage (mcg/day))(LowMedium)
Beclomethasone dipropionate CFC (168 = 504> 504 = 840) Beclomethasone dipropionate HFA
(80 = 240>240 = 640) Triamcinolone acetonide (400 = 1000>1000 = 2000)

1. ADVAIR/SERETIDE =250/50 mcg BID or Symbicort 320/9 mcg BID (i. e 160/4. 5 mcg two
inhalation BID) are not permitted.
1. Pulmonary function: A pre-albuterol (salbutamol) FEV1 of 50% and 85% of
predicted normal value at screening (Visit 1) after withholding asthma
medications as detailed in the protocol (Section 6. 8.1). Predicted FEV1 will be
based on the National Health and Nutrition Examination Survey (NHANES III)
predicted normal values for ages 8 years and older [Hankinson, 1999].
2. Reversibility: An increase in FEV1 of 12% over the pre-albuterol (salbutamol)
FEV1 within 30 minutes after the inhalation of 2-4 puffs of albuterol
(salbutamol). Historical documentation of reversibility will not be permitted.
3. Asthma symptom criteria: Each subject must have experienced asthma symptoms
requiring albuterol (salbutamol) use within the 4 weeks preceding screening
(Visit 1).
Specific information regarding warnings, precautions, contraindications, adverse
events, and other pertinent information on the investigational product that may impact
subject eligibility is provided in the IB and the product labels.
