DAW1033B2 in Obstructive Sleep Apnea

Effect of DAW1033B2 on Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) is common and has major health implications but treatment options are limited. OSA patients show a marked reduction in upper airway (UA) dilator muscle activity at sleep onset and this phenomenon leads to increased collapsibility of UA compared to normal subjects. In this protocol the investigators will test the effect of DAW1033B2 administered before sleep on OSA phenotype traits and OSA severity during sleep.
