Phase 1 Interventional George Washington University · NCT03860233

What this trial studies

This study investigates the effects of oxytocin administered via nasal spray on patients with obstructive sleep apnea who are using Continuous Positive Airway Pressure (CPAP) devices. It is a randomized, double-blinded, cross-over study involving 40 participants who will alternate between oxytocin and a placebo over a 35-night period. Participants will spend three nights in a sleep lab to monitor their sleep architecture and CPAP usage, while also providing blood samples for analysis of inflammatory markers. The goal is to determine if oxytocin can lower the pressure required from CPAP machines, potentially alleviating some harmful effects of low oxygen during sleep.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have been using a CPAP device for at least one month.

Not a fit: Patients with other sleep disorders, those unable to use CPAP, or individuals who are pregnant or breastfeeding may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a more effective treatment for obstructive sleep apnea, reducing the pressure needed from CPAP machines and improving patient comfort.

How similar studies have performed: While the use of oxytocin in this context is novel, other studies have explored the effects of various treatments on CPAP efficacy, but this specific approach remains largely untested.
