Brief Summary

The primary goals of this study will be to implement innovative processing and detection assays to qualify induced sputum measurements of markers of allergen-induced airway inflammation. The results of this study are intended to form a platform to be used in the clinical development of novel asthma therapeutics.

Study Arms (2)

Arm 1

EXPERIMENTAL

study medication + Pbo

Drug: Comparator: fluticasone; Drug: Placebo

Arm 2

EXPERIMENTAL

Pbo + study medication

Drug: Comparator: fluticasone; Drug: Placebo

Interventions

Comparator: fluticasone DRUG

Two puffs, of 250 µg each, will be administered to each patient to obtain a 500-µg dose at each prespecified time point. A total of five (5) doses (500 µg) each of inhaled fluticasone will be administered in a 3-day period during Periods 1 and 2. Dosing will be twice a day for 3 days, ending after the morning dose on the third day.

Also known as: fluticasone

Arm 1; Arm 2

Placebo DRUG

Two puffs, of placebo, will be administered to each patient at each prespecified time point. A total of five (5) doses of placebo will be administered during the single blind run-in phase. and matching placebo will be administered in a 3-day period during Periods 1 and 2. Dosing will be twice a day for 3 days, ending after the morning dose on the third day.

Eligibility Criteria

• Age: 18 Years - 55 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• Patient has a history of mild to moderate persistent allergic asthma for at least 6 months with typical symptoms, including cough, wheezing, and shortness of breath, is clinically stable and has no history of recent respiratory tract infection within 3 weeks of the start of the study
• Patient, aside history of asthma, is judged to be in good health based on medical history, physical examination, vital sign measurements, and laboratory safety tests.
• Patient is able to perform reproducible pulmonary function test.
• Patient has an allergic response to house dust mite allergen, demonstrates a positive early and late phase response to an inhaled allergen challenge (as defined by a bronchoconstrictive response)
• Patient is a nonsmoker for at least 12 months. Patients must have less than or equal to 10 pack years of smoking to be included. (10 pack years = one pack per day for 10 years.) Patients who have discontinued smoking for at least 10 months may be enrolled at the discretion of the investigator
• Patient is willing to avoid strenuous physical activity (i.e., strenuous or unaccustomed weight lifting, running, bicycling, etc.) for 72 hours prior to each visit when laboratory safety tests are obtained and 48 hours prior to allergen challenge

You may not qualify if:

• Patient has a history of any illness that, in the opinion of the study investigator, might confound the results of the study or poses additional risk to the patient by their participation in the study
• Patient has taken oral corticosteroids within 8 weeks or inhaled corticosteroids/nasal corticosteroids within 4 weeks of screening and/or during the study
• Patient has a history of stroke, chronic seizures, or major neurological disorder
• Patient has a history of clinically significant endocrine, gastrointestinal, cardiovascular, hematological, hepatic, immunological, renal, respiratory (other than asthma), or genitourinary abnormalities or diseases, or has a history of neoplastic disease
• Patient is unable to refrain from or anticipates the use of any medication other than the ones permitted in this study, including prescription and non-prescription drugs or herbal remedies prior to administration of the initial dose of study drug, throughout the study (including washout intervals between treatment periods), until the poststudy visit
• Patient consumes excessive amounts of alcohol, defined as greater than 3 glasses of alcoholic beverages per day or \>21 drink equivalents per week.
• Patient consumes excessive amounts, defined as greater than 6 servings of coffee, tea, cola, or other caffeinated beverages per day
