Evaluation of a Medical Device Based on Isotonic Seawater and Hyaluronic Acid Used as a Nasal Spray

August 25, 2026 updated by: YSLab

Clinical Performance Evaluation of a Medical Device Based on Isotonic Seawater and Hyaluronic Acid Used as a Nasal Spray in Children and Adults With Nasal Dryness: a Prospective, Multicentric, Non-randomized Study in Real-life Conditions.

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

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Improvement of the nasal dryness symptoms
Time Frame: From enrollment to the end of treatment at 1 week
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 Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Improvement of the total perceive Nasal symptom relief
Time Frame: From enrollment to the end of treatment at 1 week
The changes between the baseline and day 7 will be assessed using the Rhinitis Sicca Symptom Score (RSSS). The RSSS is constituted by the sum of the following individual symptoms: sensation of dry nose, impairment of nasal breathing/nasal obstruction, crusting, itching/sneezing attacks, pain in the nose, anterior nasal discharge /runny nose, thick nasal discharge, desire to clear one's throat/ dry throat, impairment of smell and impairment of sleep. Patients assessed with each of these symptoms 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
Safety endpoint
Time Frame: From enrollment to the end of treatment at 1 week
Adverse events, if any, will be tabulated by the investigator
From enrollment to the end of treatment at 1 week
