INS Subgroup: SNOT-22

Post hoc subgroup analysis

Improvement in SNOT-22 in patients previously
using standard nasal steroids1

Improvements in SNOT-22 scores in the subgroup of patients reporting use of standard nasal steroids prior to study entry1

  • Mean SNOT-22 scores improved by 21 points at Week 16 in patients taking XHANCE (both the 186 mcg BID dose and the 372 mcg BID dose)1
  • Minimal clinically important difference (MCID) of –9 is considered a clinically relevant improvement2,3
  • In the clinical trials for XHANCE, the mean baseline SNOT-22 score for all arms was ~501,4,5
  • In a subgroup of patients reporting use of a standard nasal steroid within 30 days of the screening visit1:

    – Patients reported a mean treatment duration of 3 years with a standard nasal steroid

  •   The results shown below are descriptive and should be interpreted with caution.

    SNOT-22 is a questionnaire for assessing symptoms, quality of life, and functioning. Patients report answers to 22 questions using a scale from 0 (“no problem”) to 5 (“problem as bad as can be”). Responses are summed, and total score ranges from 0 to 110, with a mean score of 9.3 for healthy patients.

    IMPORTANT SAFETY INFORMATION
    WARNINGS AND PRECAUTIONS:
    • Local Nasal Effects: epistaxis, erosion, ulceration, septal perforation, Candida albicans infection, and impaired wound healing. Monitor patients periodically for signs of possible changes on the nasal mucosa. Avoid use in patients with recent nasal ulcerations, nasal surgery, or nasal trauma until healing has occurred.

    Please see additional Important Safety Information and full Prescribing Information, including Instructions for Use.
