Efficacy, Safety and Acceptability of Nastent™ in Snoring and Obstructive Sleep Apnea

Study Overview
=================
Brief Summary
-----------------
This study evaluates the efficacy, the tolerance and the acceptability/compliance of the nasal airway stent, Nastent, for the treatment of mild to moderate OSA and snoring in European adult patients without cardiovascular and/or respiratory comorbidities/disorders.

Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Device : nasal airway stent<br>Patients with OSA or snoring use the nasal airway stent nastent™ each night for sleeping. The device is a tube-shaped medical device that is inserted from the nose and the tip of the tube reaches the soft palate. The inserted tube aids breathing by preventing the obstruction of the airway which causes poor sleep, frequent awakening during sleep and snoring. | Device: nastent™<br>* Snorer and OSA patients (mild or moderate OSA) use the nasal airway stent for sleeping, each night for 1 month.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Efficacy : change from baseline Snoring Intensity at 1 month | The snoring intensity will be evaluated by bed-partner of snorers and OSA patients using a Visual Analogue Scale (0-100 mm) at baseline and after 1 month of nastent™ use to assess the efficacy of treatment. | 1 month | 
| Efficacy : Change from baseline Apnea Hypopnea Index (AHI) at 1 month | The Apnea Hypopnea Index (number of apnea and hypopnea per hour) will be measured by respiratory polygraph on OSA patients subgroup at baseline and after 1 month of nastent™ use to assess the efficacy of treatment. | 1 month | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline Sleepiness at 1 month | The Epworth Sleepiness Scale (ESS) will be completed by OSA patients at baseline and after 1 month of nastent™ use to assess the evolution of somnolence/daytime sleepiness. Total score ranges between 0 and 24. A score above 10 indicates excessive daytime sleepiness. | 1 month | 
| Change from baseline Nasal Obstruction at 1 month | The NOSE questionnaire will be completed by snorers and OSA patients at baseline and after 1 month of nastent™ use to assess the efficacy of the device on the nasal obstruction.Total score ranges between 0 and 100. | 1 month | 
| Observance | The number of hours of Nastent™ use per night, the number of nights per week will be measured to assess the observance and compliance of the treatment in snorers and OSA patients during one month. | 1 month | 
| Adverse Events [Safety and Tolerability] | Adverse events reported by patient on a diary (from day 1 to day 30) and clinically observed by the physician will assess the safety and tolerability of the device. | 1 month | 
| Quality of Life using Functional Outcomes of Sleep Questionnaire (FOSQ-10) | FOSQ-10 measures functional status and difficulty in performing everyday activities via 10 questions. The questionnaire will be completed by snorer and OSA patients at baseline and after 1 month of nastent™ use to assess the evolution of the quality of life. Total score ranges between 5 and 20. Higher scores indicate better functional status. | 1 month | 
| Physician satisfaction | The physician's global satisfaction with nastent™ efficacy and safety will be assessed for each patient using a numeric scale after one month of treatment. Score ranges between 0 and 10. | 1 month |
