Assess Efficacy and Safety of a Nasal Spray in Adults With Dry or Irritated Nose
Study Details
Study Description
Brief Summary
The goal of this clinical trial is to test symptom relief in subjects suffering from irritated or dry nasal passages. The main question it aims to answer is whether use of the nasal spray provides relief from dry nose symptoms. Participants will use the product for one week and report on the severity of their symptoms before and during use.

Detailed Description
The aim of this clinical investigation is to evaluate the efficacy and safety of a product among subjects suffering from the irritated or dry nasal mucosa triggered by any causes. Sterimar Stop & Protect Irritation & Dryness, similar to other nasal saline solutions, can clean the nose and eliminates impurities, restores natural moisture, and helps prevent ear, nose, and throat (ENT) disorders, consequently improving the quality of life. The test product is a seawater-based nasal spray enriched with sodium thiosulfate pentahydrate and sodium hyaluronate and is currently marketed in France. The current study is to evaluate the clinical benefits associated with using Sterimar Stop & Protect Irritation & Dryness in the relief of nasal dryness and irritation symptoms triggered by any causes.
60 subjects will be included in this single arm open label study.
Study product will be used as 1 to 2 sprays per nostril (each "dose" is 1 or 2 sprays per nostril, the second spray only if needed), for a minimum of 2 times (morning and evening) and, as needed, up to a maximum of 6 times per day (i.e., maximum 12 sprays per nostril each day) for seven days.

Outcome Measures
Primary Outcome Measures
- Change in patient-reported total irritation score from baseline [One week of product use.]
Sum of scores of 12 symptoms: nasal dryness, nasal crusting, nasal bleeding, nasal itching, nasal burning, nasal obstruction, nasal pain, nasal discomfort, sneezing, reduced sense of smell, external nasal redness, and external nasal swelling. Total score ranges from 0 to 36 in 0.5 unit increments with higher scores indicating more severe symptoms. (Lower is better)
Secondary Outcome Measures
- Change in patient-reported symptom score from baseline for each of the 12 symptoms from baseline to day 7. [One week of product use.]
7-point scale from 0 to 3 in 0.5-unit increments with higher scores indicating more severe symptoms. (Lower is better) nasal dryness, nasal crusting, nasal bleeding, nasal itching, nasal burning, nasal congestion, nasal pain, nasal discomfort, sneezing, reduced sense of smell, external nasal redness, external nasal swelling
- Change in patient-reported quality of life question from baseline to day 7. [One week of product use.]
5-point scale for seven questions, plus one yes/no question. Scores range from 1 (very good) to 5 (very poor) in 1 unit increments. Yes/no on whether symptoms would have been treated if not in the study (yes means symptoms severe enough to treat).
- Day on which a state of well-being of nose was achieved. [One week of product use.]
Day 0 to Day 7 or not at all.
- Change from baseline in morning/evening total irritation and individual symptom scores. [One week of product use.]
Each symptom on a 7-point scale from 0 to 3 in 0.5-unit increments with higher scores indicating more severe symptoms. (Lower is better) Sum of symptom scores is total irritation score.
- Immediate relief for individual symptom scores after first product application of the day. [1 minute, 10 minutes, and 1 hour after first application on day 0 and on day 6.]
Each symptom on a 7-point scale from 0 to 3 in 0.5-unit increments with higher scores indicating more severe symptoms. (Lower is better)
- Duration of relief of first dose each day. [One week of product use.]
Time between first and second product application of the day.
- Change from baseline in sleep disturbance scores [One week of product use.]
Assessment of quality of sleep will be evaluated by means of a questionnaire ("Quality of Sleep Questionnaire"), on a 0 to 3-point scale, with higher score indicating a worse outcome, with 0=not at all, 1=slightly, 2=moderately and 3=severely, to be completed from Day 0 (baseline) and daily from the beginning to the end of the study.
- Change from baseline in examiner symptom scores for dryness, atrophy, redness, oedema, crusting, and bleeding. [One week of product use.]
Each symptom on a 7-point scale from 0 to 3 in 0.5-unit increments with higher scores indicating more severe symptoms. (Lower is better)
