DAW1033B2 in 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.

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion Criterion:

  • OSA: AHI > 15

Exclusion criteria

  • Any medical condition other than well controlled hypertension, diabetes, hyperlipidemia
  • Any medication known to influence breathing, sleep/arousal or muscle physiology.
  • Claustrophobia.
  • Inability to sleep supine.
  • Allergy to lidocaine, Oxymetazoline HCl, DAW1033D.
  • Individuals with underlying cardiac disease, such as arrhythmias.
  • Individuals taking psychiatric medications, or any of the studied medications for medical care.
  • History of seizures

Treatment and study plan

Placebo oral capsule

Drug

Placebo capsule 30 minutes before sleep

DAW1033B2 oral capsule

Drug

DAW1033B2 capsule 30 minutes before sleep

Primary outcomes

  1. Apnea Hypopnea Index (AHI, Events/Hour of Sleep)

    Time frame: 1 night

    Based on previous studies the investigators anticipate that DAW1032B2 will reduce AHI more effectively in subjects with moderate sleep apnea, mildly obese (BMI<32), Vpassive > 50% of Veupnea (ventilation during eupneic ventilatory drive)
