Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with obstructive sleep apnea, where breathing stops often during sleep. It tests capsules taken before bedtime.

Age
18 Years to 70 Years
Sex
All sexes can join.
Disease stage
Obstructive sleep apnea with AHI > 10 events/h (breathing pauses per hour) during NREM sleep while lying on the back. Severe sleep apnea with a mean SaO2 (blood oxygen) lower than 88% cannot join.
Earlier treatment
People taking any medicine known to affect breathing, sleep, waking or muscles cannot join. People taking psychiatric medicines such as an MAO-I, SSRI or SNRI cannot join.
Biomarker or test result
AHI > 10 events/h during NREM supine sleep.

Main reasons for not taking part

  • Any medical condition other than well controlled high blood pressure and mild diabetes
  • Heart disease such as irregular heartbeat, or pulmonary hypertension
  • History of kidney stones, high calcium, primary hyperparathyroidism, sarcoidosis or too much vitamin D
  • Pregnancy, fear of closed spaces, or not able to sleep on the back

About the trial

What the trial wants to find out

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.
