Open label Dronabinol treatment for two weeks.
MarinolLoading study record…
This is an open-label trial that tests the effectiveness of Dronabinol in treating obstructive sleep apnea (OSA). All participants will take oral Dronabinol for two weeks. Sleep studies will be conducted before and after treatment to measure OSA severity.

Registry facts
Obstructive sleep apnea (OSA), is a serious respiratory disorder that involves repetitive cessation of breathing during sleep. It is estimated that 15-20 million people in the United States suffer from OSAS, which has been linked to increased risk for hypertension, heart failure, depression, and diabetes. The current standard of care for OSA, positive airway pressure (PAP), involves a mechanical device with low patient tolerance and adherence. Upper airway surgical approaches are also an option but are invasive and often unsuccessful. Effective drug treatments for OSA remain to be identified. This study will enroll up to 120 Veterans so that 45 Veterans may complete the two-week open-label Dronabinol treatment trials. The results of the study will be used to develop a prediction model for OSA severity reduction after 2-week Dronabinol treatment vs. pretreatment AHI. Participants clinical (age, sex, body mass index, comorbidity) and pretreatment polysomnographic characteristics (sleep architecture, respiratory disturbance, and endotypes; loop-gain, arousal threshold, upper airway collapsibility and compensation) will be used to develop a prediction model for improvement of OSA with Dronabinol treatment. This prediction model will be used for a randomized clinical trial after the completion of this trial.

primary outcomes
Time frame: 2 weeks
The change in AHI after two weeks of Dronabinol treatment will be determined from before and after treatment polysomnograms.
secondary outcomes
Time frame: 2 weeks
The change in time below 90% oxygen saturation (T\<90) after two weeks of Dronabinol treatment will be determined from before and after treatment polysomnograms.
other outcomes
Time frame: 2 weeks
The change in Lapses on Psychomotor Vigilance Test (PVT) after two weeks of Dronabinol treatment will be determined from before and after treatment PVT using a 10 minute protocol.
Time frame: 2 weeks
The change in 24- hour mean arterial blood pressure after two weeks of Dronabinol treatment will be determined from before and after treatment 24-hiur ambulatory BP recording.
Time frame: 2 weeks
The change in sleep efficiency after two weeks of Dronabinol treatment will be determined from before and after treatment polysomnograms.
Time frame: 2 weeks
The change in REM sleep after two weeks of Dronabinol treatment will be determined from before and after treatment polysomnograms.
Time frame: 2 weeks
The change in slow wave sleep after two weeks of Dronabinol treatment will be determined from before and after treatment polysomnograms.
Time frame: 2 weeks
Patient reported treatment satisfaction. TSQM scores have a range of 0 to 100, with higher scores indicating higher satisfaction.
Time frame: 2 weeks
The change in Epworth Sleepiness Scale (ESS) will be measured after two weeks of Dronabinol treatment. ESS scores have a range of 0 to 24, with higher scores indicating greater sleepiness.
Time frame: 2 weeks
The change in Functional Outcomes of Sleep Questionnaire (FOSQ) will be measured after two weeks of Dronabinol treatment. FOSQ score ranges from 5-20, with higher scores indicating better functional status.
Time frame: 2 weeks
The change in Pittsburgh Sleep Quality Index (PSQI) will be measured after two weeks of Dronabinol treatment. The PSQI score ranges from 0 to 21. Higher scores indicate poorer sleep quality.

The change in Insomnia Severity Index (ISI) will be measured after two weeks of Dronabinol treatment. ISI ranges from 0 to 28, with higher scores indicating greater sleep disturbance.
Time frame: 2 weeks
The change in Post-Traumatic Stress Disorder; PTSD checklist (PCL-5) will be measured after two weeks of Dronabinol treatment. PCL-5 scores range from 0 to 80, with higher scores indicating greater PTSD symptom severity.
