简要总结
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 LTM1201L, LTM1201LN, LTM1201LB, LTM1201LD administered before sleep on OSA phenotype traits and OSA severity during sleep.

结局指标
主要结局
Apnea Hypopnea Index (AHI, Average Number of Events for Every Hour of Sleep)
时间窗: 1 night
Based on previous studies the investigators anticipate that active comparators will reduce AHI more effectively in subjects with moderate sleep apnea and low-to-moderate collapsibility (Vpassive \>50% of eupneic values). Higher AHI indicates more severe OSA, usually ranging between 10 to 110 events/hour.
次要结局
