A Study to Compare the Bioavailability Intranasal Administration of 200 and 400 µg or 400 µg Alone of OPTINOSE™ FLUTICASONE With 440 µg of Flovent® HFA (Fluticasone Propionate) Inhalation Aerosol (Part 2)

Study Overview
=================
Brief Summary
-----------------
To compare the systemic exposure of a single dose of 400 µg of OPTINOSE FLUTICASONE with 440 µg of Flovent® HFA (fluticasone propionate) Inhalation Aerosol in asthmatic subjects.

Official Title
-----------------
An Open-Label, 2-Part, Randomized, Crossover Study to Compare the Bioavailability of Intranasal Administration of 200 and 400 µg of OPTINOSE™ FLUTICASONE With 400 µg of Flonase® (Fluticasone Propionate) Nasal Spray (Part 1), and Intranasal Administration of 200 and 400 µg or 400 µg Alone of OPTINOSE™ FLUTICASONE With 440 µg of Flovent® HFA (Fluticasone Propionate) Inhalation Aerosol (Part 2) (Current Investigation is Part 2 Only)

Conditions
-----------------
Mild to Moderate Asthma

Intervention / Treatment
-----------------
* Drug: Flovent HFA
* Drug: OPTINOSE™ FLUTICASONE


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Male or female subjects' ages 18 to 55 years, inclusive, at screening. Have a body mass index of 18 to 32 kg/m2, inclusive, and a body weight of not less than 52 kg for males and 45 kg for females. Otherwise healthy mild to moderate asthmatic (Part 2) with no clinically relevant abnormalities in the opinion of the Investigator as determined by medical history, physical examination, blood chemistry, hematology (including complete blood count), serology, urinalysis, vital signs, and ECG performed at screening. History of mild to moderate asthma, diagnosed by a physician, which is well controlled at the present time (no history of sudden or severe asthma exacerbation in the past 12 months). Are unlikely to exacerbate during the study due to seasonal allergen exposure. Able to tolerate withdrawal of their medication for a required period of time. Exclusion Criteria: Currently have or have a history of disease or dysfunction of the cardiovascular, endocrine, hematologic, neurological, immune, gastrointestinal, genitourinary, musculoskeletal, or other body system that is clinically significant in the opinion of the Investigator. History of smoking or use of nicotine-containing substances within the previous 3 months before screening. Hypersensitivity to fluticasone propionate or any of the excipients found in OPTINOSETM FLUTICASONE or Flovent® HFA (for Part 2). History of extensive nasal and/or sinus surgery. Known nasal obstruction including allergic rhinitis, nasal septal deviations, polyposis, severe mucosal swelling, nasal ulcers, nasal trauma or any other reason. History of acute severe asthma attacks. History of seasonal asthma exacerbation, in which case subjects should be outside the relevant allergen season. Have evidence of any chronic medical conditions other than asthma requiring prescription medications (e.g., hypertension or diabetes). Have used inhaled, intranasal, oral, or injectable corticosteroids within 4 weeks prior to dosing. Subjects should be on stable treatment for at least 1 month prior to withdrawal.
