Reduction in Sino-Nasal Outcome Test-22 (SNOT-22) Scores*

 

XHANCE clinical trial design

XHANCE has been extensively studied in over 1600 patients

Phase 3 Trials Demonstrating Efficacy and Safety
Two similar randomized, placebo-controlled multicenter studies to assess XHANCE safety and efficacy (N=646).1,2

Flow chart showing the study design and clinical trial format for NAVIGATE I and NAVIGATE II Flow chart showing the study design and clinical trial format for NAVIGATE I and NAVIGATE II

NAVIGATE I: placebo EDS, n = 82; XHANCE 186 mcg BID, n = 80; XHANCE 372 mcg BID, n = 80.
NAVIGATE II: placebo EDS, n = 80; XHANCE 186 mcg BID, n = 80; XHANCE 372 mcg BID, n = 82.

Coprimary endpoints1,2:

  • Reduction of nasal congestion/obstruction symptoms at Week 4
  • Reduction in total polyp grade at Week 16

Secondary endpoints include1,2:

  • Change from baseline in nasal congestion/obstruction, sense of smell, rhinorrhea, and facial pain or pressure
  • Subject assessment of Patient Global Impression of Change (PGIC) at Week 16
  • Secondary endpoints were not controlled for Type I error

Key inclusion criteria1,2:

  • Bilateral nasal polyps (grade 1 to 3)
  • Moderate to severe symptoms of nasal congestion/obstruction

Details1,2:

  • A liquid placebo comparator was delivered using an Optinose Exhalation Delivery System (EDS)
  • In the pivotal clinical trials, 91% of patients reported previous use of a nasal steroid for the treatment of nasal polyps, and 54% reported previous sinus surgery or polypectomy
  • Patients and physicians remained blinded to initial treatment throughout the 8-week open-label extension
  • Patients with history of allergic rhinitis could participate in the study provided their “season” did not coincide with the first 4 weeks of the study
  • Subjects were allowed to use nonsedating antihistamines as “rescue” after Week 4 in an effort to reduce placebo dropout

*Multiplicity adjustments were not applied for secondary endpoints and results could represent chance findings; therefore, these data and comparisons between studies require cautious interpretation.

The comparator used in the pivotal clinical studies was a liquid placebo delivered with an Optinose Exhalation Delivery System (EDS).1

Results shown above are from NAVIGATE II and are consistent with results observed in patients participating in NAVIGATE I.1
