Brief summary: The primary objective of this study is to compare the efficacy of intranasal administration of 100, 200, and 400 μg of fluticasone propionate twice a day delivered by the OptiNose device with placebo in subjects with bilateral nasal polyposis. Two co-primary endpoints will be used in the study: reduction of nasal congestion/obstruction symptoms at the end of Week 4 of the double-blind treatment phase measured by the 7 day average instantaneous AM diary symptom scores, and reduction in total polyp grade (sum of scores from both nasal cavities) over the 16 weeks of the double-blind treatment phase as determined by the Lildholdt scale score measured by nasoendoscopy.

Detailed description: This was a randomized, double-blind, placebo-controlled, parallel-group, multicenter study designed to assess the efficacy and safety of intranasal administration of 3 doses of OPN-375 (100, 200, and 400 µg bid) in subjects with bilateral nasal polyposis and nasal congestion.

This study consisted of 3 phases. After signing informed consent, subjects who met eligibility criteria at Visit 1 (screening) entered the study.

1. Pretreatment phase (single-blind, placebo, run-in): 7 to up to 14 days duration, to determine disease status eligibility and to ensure the subject was able to comply with study procedures prior to randomization and enrolment in the double-blind treatment phase.
2. Double-blind treatment phase: 16 weeks duration with 6 scheduled visits starting with Visit 2, Day 1 (baseline) when eligible subjects were randomized by balance allocation to 1 of 4 treatment groups and ending at Visit 7 (Week 16).
3. Open-label extension phase: 8 weeks duration with 1 scheduled visit (Visit 8 \[Week 24\]).

Eligibility criteria: Inclusion Criteria:

* Men or women aged 18 years and older
* Women must

  * be practicing an effective method of birth control (eg,prescription oral contraceptives, contraceptive injections, contraceptive patch, intrauterine device, double-barrier method \[eg, condoms, diaphragm, or cervical cap with spermicidal foam, cream, or gel\], or male partner sterilization) before entry and throughout the study, or
  * be surgically sterile (have had a hysterectomy or bilateral oophorectomy, or tubal ligation at least 1 year before screening) or otherwise be incapable of pregnancy, or
  * be postmenopausal (spontaneous amenorrhea for at least 1 year).
* Women of child-bearing potential must have a negative serum beta-human chorionic gonadotropin (B-hCG) or urine pregnancy test (depending on local regulations) at the screening visit
* Must have bilateral nasal polyposis with a grade of 1 to 3 in each of the nasal cavities as determined by the Lildholdt scale score measured by nasoendoscopy at both screening and baseline visits
* Must have at least moderate symptoms of nasal congestion/obstruction as reported by the subject for the 7 day period preceding the screening visit
* At the baseline visit (Day 1), must have a morning score of at least 2 (moderate) on nasal congestion/obstruction recorded on the subject diary for at least 5 of the last 7 days of the 7 to up to 14 day run-in period
* Must demonstrate an ability to correctly complete the daily diary during the run-in period to be eligible for randomization
* Subjects with comorbid asthma or COPD must be stable with no exacerbations (eg, no emergency room visits, hospitalizations, or oral or parenteral steroid use) within the 3 months before the screening visit. Inhaled corticosteroid use must be limited to stable doses of no more than 1,000 μg/day of beclomethasone (or equivalent) for at least 3 months before screening with plans to continue use throughout the study.
* Must be able to cease treatment with intranasal medications including, but not limited to, intranasal steroids, intranasal sodium cromolyn, nasal atropine, nasal ipratropium bromide, inhaled corticosteroids (except permitted doses listed above for comorbid asthma and COPD) at the screening visit
* Must be able to cease treatment with oral and nasal decongestants and antihistamines at the screening visit
* Must be able to use the OptiNose device correctly; all subjects will be required to demonstrate correct use of the placebo device at screening, Visit 1.
* Must be capable, in the opinion of the investigator, of providing informed consent to participate in the study. Subjects must sign an informed consent document indicating that they understand the purpose of and procedures required for the study and are willing to participate in the study.

Exclusion Criteria:

* Women who are pregnant or lactating
