Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this post-market clinical investigation is to assess in a real-life setting, the effectiveness, usage, tolerance, safety and satisfaction of 4 isotonic and hypertonic seawater-based CE-marked nasal sprays.
The main questions it aims to answer are:
- Efficacy,
- Safety,
- Usage,
- Satisfaction, in real-life usage among infants, children, adults and pregnant or breastfeeding women suffering from acute and chronic sinonasal pathologies. The 4 medical devices under investigation will be used in accordance with their intended use, target populations and medical indications.
