Overview
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.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Male and female subjects ≥18 years of age;
- •Subjects must have ongoing nasal irritation or dryness at Visit 1 (Day -4);
- •Total Irritation Score (sum of all 12 symptom scores) must average at least 8 over the three-day run-in period (Day -3 to -1) and must be at least 8 at Visit 2 (Day 0). (Individual symptom score range is 0 - 3; Total Irritation Score range is 0 - 36.)
- •Dry Nose Symptom Score must average at least 2 over the three-day run-in period and must be at least 2 at Visit 2 (Day 0). (Dry nose symptom score range is 0 - 3.)
- •The score of at least two other symptoms beside dry nose must average at least 2 over the three-day run-in period and must be at least 2 at Visit 2 (Day 0). (Each symptom score range is 0 - 3.)
- •Twenty-five percent of the included subjects must have ongoing nasal symptoms caused by indoor pollutants from fireplaces, candles, smoking, or cooking, verified by principal investigator;
- •Subjects are willing to refrain from using any medications and/or acts for relief of nasal symptoms during the whole study from Day -4 to Day 7; except for acetaminophen, ibuprofen, or vitamins;
- •Subjects are willing and able to comply with the requirements of the study to use the study product according to use instructions, complete the daily symptom and product diaries and questionnaire(s), and visit the test facility as instructed;
- •Subjects can read, understand, and sign an informed consent document after being advised of the nature of the study.
Exclusion Criteria
- •Currently taking any over-the-counter and prescription systemic/topical corticosteroids, antibiotics, antihistamines, cromone, nonsteroidal anti-inflammatory drugs (NSAIDs), leukotriene antagonists or topical or systemic decongestants within the two weeks prior to Visit 1;

- •Women who are pregnant and/or breastfeeding or planning to become pregnant during the study and within 30 days after the last application of the study product;
- •Have a dermatologic, respiratory, or medical condition (e.g., asthma, pneumonia, laryngotracheobronchitis, sinusitis, etc.) which, in the opinion of the principal investigator, could interfere with the interpretation of study results at the time of the screening visit (Day -4);
- •Have a positive medical history of any significant illness within the 2 weeks prior to the screening visit (Day -4), which, in the opinion of the principal investigator, could interfere with the interpretation of study results;
- •Have a known allergy to any food or personal care products;
- •Have any kind of immunodeficiency;
- •Have a history of sensitivity to products as related to the product being evaluated;
- •Positive Coronavirus disease (COVID-19) test during the month before the study or during the study;

Outcomes
Primary Outcomes
Change in patient-reported total irritation score from baseline
Time Frame: 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 Outcomes
- Change in patient-reported symptom score from baseline for each of the 12 symptoms from baseline to day 7.(One week of product use.)
- Change in patient-reported quality of life question from baseline to day 7.(One week of product use.)
- Day on which a state of well-being of nose was achieved.(One week of product use.)
- Change from baseline in morning/evening total irritation and individual symptom scores.(One week of product use.)
- 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.)
- Duration of relief of first dose each day.(One week of product use.)
- Change from baseline in sleep disturbance scores(One week of product use.)
- Change from baseline in examiner symptom scores for dryness, atrophy, redness, oedema, crusting, and bleeding.(One week of product use.)
