Two Seawater-based Formulations for Relief of Nasal Congestion in Paediatric Subjects

A Multicentre, Randomised, Open Label, Parallel Group, Controlled Clinical Trial to Evaluate Efficacy and Tolerability of Two Seawater-based Formulations Plus a Standard of Care Versus the Standard of Care Alone for Relief of Nasal Congestion in Paediatric Subjects With Common Cold

The objective of this clinical trial is to evaluate the tolerance and efficacy of two Stérimar nasal sprays products in children who have nasal congestion due to the common cold.

This clinical trial is a multicentre, randomized, parallel-group, controlled, open-label clinical trial to evaluate the efficacy of two Stérimar nasal sprays formulations (medical device already CE marked) for nasal congestion in children aged 3 to 48 months with common cold. In total the study foresees 300 patients divided between the different clinical sites.

4. Subjects with nasal congestion (blocked / stuffy nose) rated as at least grade 2 (moderately bothersome) on a 0 to 2-point scale, based on morning evaluation (within an hour of subject awakening).
5. Subjects showing at least grade 2 on a 0 to 2-point scale for at least one of the following additional signs of cold symptoms: runny nose, nasal crust (dry mucus), thick mucus, sneezing and cough.
6. Legal caretaker(s) signed written informed consent for their young ones to participate in the study.
7. Legal caretaker(s) willing to comply with all study procedures.

5. Subjects presenting any congenital or chronic disease that in the opinion of the Investigator would adversely affect the results of the study (e.g., asthma, pneumonia, laryngotracheobronchitis, sinusitis, and so on).
