Clinical Trial Summary

Obstructive sleep apnea syndrome (OSAS) is a common disease, affecting 10-15% of the general adult population. This pathology is characterized by iterative nocturnal episodes of complete or partial obstruction of the upper airways during sleep leading to chronic intermittent nocturnal hypoxia and sleep fragmentation. The number of nocturnal respiratory anomalies per hour of sleep characterizes the severity of the disease with a gradual gradation of severity from mild (from 5 to 15 anomalies per hour) to moderate (15 to 30 anomalies per hour) and severe (over 30 anomalies per hour). The rationale for this severity classification is the increase in morbidity and mortality proportional to the severity of OSA as defined.

OSA is accompanied by a fragmentation of sleep often responsible for excessive daytime sleepiness, causing an increase in occupational accidents with work stoppage and traffic accidents.

The second consequence of repeated nocturnal obstructions is chronic intermittent nocturnal hypoxia which has deleterious cardiovascular effects, constituting an independent cardiovascular risk factor.

Shear waves are elastic waves of low frequency (less than 1000 oscillation per second - 1000Hz). It propagates only in solids and soft solids such as the human body. The propagation of a shear wave generates a reversible micrometric displacement of the particles that make up this medium. The energy of these waves is related to the amplitude of movement of the particles.

Elastography is an imaging modality for measuring the elasticity of biological tissues by shear waves. The shear wave is a mechanical wave sensitive to the change in the elasticity of its propagation medium. This sensitivity is manifested by the variation of its propagation speed. Hardness results in acceleration of the wave and softness in its slowing down.

The therapeutic use of shear waves has never been used for the treatment of sleep apnea but its use could be an additional therapeutic arsenal of Continuous Positive Pressure.

The technology developed by BREAS MEDICAL AB is based on the use of shear waves for the treatment of sleep apnea. The treatment is delivered using a cervical collar equipped with six sources (vibrating pistons) generating shear waves. The treatment generates shear waves at frequencies that vary from 20 to 250 Hz continuously, and at amplitudes less than 50 microns of the same order of magnitude of vibration as snoring. In view of the innovative nature of the treatment, the medico-technical team of BREAS MEDICAL AB carried out an analysis of the risks related to the device and to the propagation of waves, including the norms and standards imposed by the competent bodies.

The investigators would like, in a first-dose study in humans, to assess safety in patients with sleep apnea syndrome.
