• 1 other identifier: 2025-A00666-43
• Study Type: interventional
• Target: N/A
• Locations: 1 country
• Sites: 1

Brief Summary

The purpose of this study is to see whether the nasal spray can help improve hydration of the nasal mucosa, reduce discomfort linked to nasal dryness, and confirm its safety in patients suffering from nasal dryness.

Conditions

Nasal Dryness

Outcome Measures

Primary Outcomes (1)

• Improvement of the nasal dryness symptoms

  The changes between the baseline and day 7 in the rhinoscopy score will be assessed. The rhinoscopy score is constituted by the sum of the following symptom: dryness, atrophy, redness, oedema of the nasal mucosa and crusting. The clinician will assess each symptom on an ordinal scale of 0-4 (0 = none, 1 = mild, 2 = moderate, 3 = strong, 4 = very strong).

  From enrollment to the end of treatment at 1 week

Secondary Outcomes (2)

• Improvement of the total perceive Nasal symptom relief

  From enrollment to the end of treatment at 1 week

• Safety endpoint

  From enrollment to the end of treatment at 1 week
