Description

Summary

This is a 24-week randomized, double-blind, placebo-controlled, parallel-group, multicenter study to evaluate the efficacy and safety of intranasal administration of 186 and 372 μg twice daily (BID) of OPN-375 in subjects with chronic sinusitis (CS) with or without nasal polyps.

Official Title

A 24-Week Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Multicenter Study Evaluating the Efficacy and Safety of Intranasal Administration of 186 and 372 μg of OPN-375 Twice a Day (BID) in Subjects With Chronic Sinusitis With or Without the Presence of Nasal Polyps

Details

The primary objective of this study is to compare the efficacy of intranasal administration of twice-daily doses of 186 and 372 µg of OPN-375 (fluticasone propionate) with placebo in subjects with chronic sinusitis using the following co-primary endpoints:

  1. A change from baseline in symptoms as measured by a composite score of nasal congestion, facial pain or pressure sensation, and nasal discharge (anterior and/or posterior) at the end of Week 4.
  2. A change from baseline to Week 24/Early Termination (ET) in the average percent of the volume opacified in the ethmoid and maxillary sinuses.

  8. nasal congestion
  9. nasal discharge (anterior and/or posterior nasal discharge)
  10. facial pain or pressure
  11. reduction or loss of smell
  12. endoscopic evidence of nasal mucosal disease, with edema, purulent discharge, or polyps in middle meatus, bilaterally
  13. must have confirmatory evidence via a computed tomography(CT) scan of bilateral sinus disease (have at least 1 sinus on each side of nose with a Lund-Mackay score of ≥1)
  14. baseline CT scan must show a combined ≥25% opacification of the ethmoid sinuses and ≥25% opacification of at least 1 maxillary sinus
  15. must have at least moderate symptoms (as defined in protocol), of nasal congestion as reported by the subject, on average, for the 7-day period preceding Visit 1 (Screening) run-in
  16. must have an average morning score of at least 1.5 for congestion (as defined in protocol) recorded on the subject diary for a 7 days period of the single-blind run-in
  17. . must demonstrate an ability to correctly complete the daily diary during the run-in period to be eligible for randomization
  18. . subjects with comorbid asthma or chronic obstructive pulmonary disorder (COPD) must be stable with no exacerbations (eg, no emergency room visits, hospitalizations, or oral or parenteral steroid use) within the 3 months before Visit 1 (Screening). 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 Visit 1 (Screening) with plans to continue use throughout the study.

  21. . must be able to use the exhalation delivery system correctly; all subjects will be required to demonstrate correct use of the practice exhalation delivery system (EDS) at Visit 1 (Screening).
  22. . 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.
