- •1. Male or females adults, aged 15 to 70 years, have atopic mild persistent asthma at step 2 of the Guidelines for the Diagnosis and Management of Asthma issued by the National Heart, Lung, and Blood Institute of the National Institute of Health as defined by a history of symptoms more than twice a week but less than daily (step 2). 2. Current asthma treatment includes short-acting inhaled -agonist alone as needed. 3. Positive skin prick testing. 4. Patient fulfills all the following signs and symptoms of asthma by visit 2: a) History of symptoms including, but not limited to dyspnea, wheezing, chest tightness, cough, or sputum production for at least 12 months. b) A forced expiratory volume in one second (FEV1) of at least 80% of the predicted value (pre-bronchodilator) while withholding -agonist for at least six hours. This must be demonstrated twice at visits 1 and 2. c) Patient has a diagnosis of asthma as defined by 1) an increase in FEV1 or PEF of ≥12% (absolute value), 20 to 30 minutes after inhaled -agonist administration at visits 1, OR 2) a positive methacholine PC20 (provocative concentration causing a 20% fall in FEV1) of 8 mg/ml or lower which was performed within the previous 12 months, OR 3) a fall in FEV1 of at least 15% after an exercise challenge which was performed within the previous 12 months. -agonist reversibility and the methacholine and exercise challenge tests may be satisfied within the previous 12 months if there is adequate source documentation. 5. Patient is able to chew a tablet and inhale drug from a dry powder inhaler. 6. Patient is judged to be in good, stable physical and mental health (except for his/her asthma) based on the medical history, physical examination, and routine laboratory data, and appears able to successfully complete this trial. 7. Ability to perform reproducible spirometry. 8. Nonsmoker including no use of smokeless tobacco products in the past year. 9. Ability of parent to provide informed consent, as evidenced by signing a copy of the consent form approved by the institutional review board of the subject s respective study institution, with assent from the child. 10. Women give up pregnancy throughout the study duration (5 weeks). - atopic non asmatic patients

- •1. Patient is, in the opinion of the investigator, mentally or legally incapacitated preventing informed consent from being obtained, or cannot read or comprehend written material. 2. Patient is hospitalized. 3. Patient has undergone any major surgical procedure within four weeks of visit 1. 4. Patient has, in addition to asthma, any active, acute or chronic pulmonary disorder documented by history or physical examination. 5. Patient has ever been intubated for asthma, has required acute asthma therapy treated in an emergency room/urgent care facility/office setting within one month or has been hospitalized for asthma within three months of visit 1 or required 2 or more hospitalizations for asthma in the past year. 6. Patient has FEV1 < 80% predicted on visit 1, nighttime awakenings from asthma 2 or more times per week, or PEF variability of 30% or more. 7. Patient received 4 or more oral corticosteroid bursts for asthma exacerbations in the past year. 8. Patient has unresolved symptoms and signs of an upper respiratory tract infection (URI) within three weeks of visit 1 or during the run-in period. 9. Patient has a history of an anaphylactic allergic reaction related to administration of either a marketed or investigational drug or is otherwise hypersensitive to inhaled -agonist or oral montelukast or inhaled fluticasone or their components. 10. Patient has a clinically significant, active disease of the gastrointestinal, cardiovascular, hepatic, neurological, renal, genitourinary, or hematological systems, or an immunodeficiency, or an autoimmune disorder. 11. Patient has a history of any illness that would require treatment with an excluded medication, could be immediately life threatening, would pose restriction on participation or successful completion of the study, or would pose an additional risk to the patient by administering the study drugs. 12. Patient has taken the following medications: a) Oral, intravenous, intramuscular, intra-articular or inhaled corticosteroids within 4 weeks of visit 1 with the exception of nasal corticosteroids administered on a continuous basis. b) Leukotriene modifiers, theophylline derivatives, or mast cell stabilizers for asthma within 2 weeks before visit 1. c) Received treatment within the previous 4 week with medications known to significantly interact with montelukast. d) Antibiotics for 7 consecutive days in the 4 weeks prior to visit 1. e) IV gammaglobulin or immunosuppressants within one month of visit 1. 13. Patient has started immunotherapy within six months of visit 1. 14. Patient is unable or unwilling to comply with the study procedures as determined during the run-in period, including compliance with study medication.
