Summary

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

currently non-pregnant and non-lactating. A female is eligible to enter and participate in the study if she is: 1. of non-child-bearing potential; OR 2. of child-bearing potential but has a negative urinary pregnancy test at Screening (Visit 1 and when specified in Appendix 1) and agrees to take contraceptive precautions (including abstinence) which are adequate to prevent pregnancy during the study. Acceptable methods of contraception [Hatcher, 2004] are:

- double barrier method: condom or occlusive cap (diaphragm or cervical/vault

caps) plus spermicidal agent 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) Flunisolide (500 = 1000> 1000 = 2000) Fluticasone propionate inhalation aerosol (176 = 220> 220 = 440) Fluticasone propionate inhalation powder (100 = 250> 250 = 500) Budesonide1 (200 = 600> 600 =1200) Mometasone (200 = 400> 400 = 800) Ciclesonide (80 = 160>160 = 320) 1. Respules are allowed at a dosage of 250-500mcg/day. Table 2 (Asthma Controller Medications) Asthma Controller Medication(s) Low dose ICS + Leukotriene modifiers Low dose ICS + Theophylline products Low Dose ICS + Inhaled anticholinergics or combination products (e. g., Atrovent or Combivent) Low Dose ICS + Long acting inhaled anticholinergic (e. g. Spiriva) Low dose ICS+ long acting beta agonist or combination products containing a low dose ICS and a long-acting beta-agonists (e. g. ADVAIR™/SERETIDE™1 100/50 mcg BID or Symbicort 160/9 mcg BID (i. e 80/4. 5 mcg two inhalations BID) 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. Exclusion Criteria:

- Subjects meeting any of the following criteria must not be enrolled in the study:

1. Life-Threatening Asthma: A subject must not have life-threatening asthma. Life-threatening asthma is defined for this protocol as a history of significant asthma episode(s) requiring intubation associated with hypercapnia, respiratory arrest, or hypoxic seizures, or asthma-related syncopal episode(s) within the 12 months prior to screening (Visit 1). 2.
