- Conditions
- Allergic Rhinitis
- Interventions
- Device: Seawater nasal spray
- Registration Number
- NCT05506709
- Lead Sponsor
- Church & Dwight Company, Inc.
- Brief Summary
The study aims to confirm the safety and performance of a hypertonic seawater-based nasal spray enriched with manganese and calcium, in relief/reduction of nasal symptoms (congestion, itchy nose, runny nose and sneezing) among subjects with symptomatic allergic rhinitis. This will be a prospective, longitudinal, single-cell and product blinded clinical trial. A sufficient number (65-70) of adult subjects with allergic rhinitis meeting all eligibility criteria will be enrolled in this study to ensure that approximately 50 subjects complete the study. Subjects will be enrolled during allergy season. The study will consist of four visits with a total duration of 3 weeks (1 week of pre-screening and 2 weeks for investigational product use). The full schedule of events is presented in the CIP. Subjects recruited for this study will be screened for inclusion/exclusion criteria after reading and signing the informed consent form. Eligible subjects who show a positive reaction to the skin prick test at Visit 1/ Day -7 will be enrolled for a one-week pre-run screening period. At baseline (Visit 2/Day 0), those subjects meeting all inclusion criteria including the results of the Total Nasal Symptoms Score will be enrolled in the active study phase. The subjects will use the product during two weeks (from Day 7 to Day 14), applying at least once and maximum 6 times daily per instructions for use.
At each visit within intervention period (Visits 2, 3 and 4), the subjects will be asked to assess their nasal and ocular symptoms (using Nasal Symptom Score and Ocular Symptom Score grading tools) before product application, as well as at 1 minute, 10 minutes and 1-hour post-product application. Besides, they will complete Weekly Rhinitis questionnaire for the past week. Additionally, the subjects will complete Daily Diaries to record their nasal and ocular symptoms, sleep disturbance, and need for use of other medication.
