NCT03858751

Brief Summary

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 LTM1201AZ, LTM1201AT, LTM1201AD, LTM1201AG administered before sleep on OSA phenotype traits and OSA severity during sleep.

Outcome Measures

Primary Outcomes (1)

  • Apnea hypopnea Index (AHI, average number of events for every hour of sleep)

    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.
