About this study
Official title: A Phase II, Eight Week, Multi-Center, Open Label Trial of Xyrem(R) (Sodium Oxybate) for Excessive Daytime Sleepiness and Nocturnal Sleep Disturbance in Patients With Mild to Moderate Parkinson's Disease
This clinical trial is designed to evaluate the safety and potential efficacy of Xyrem for the treatment of excessive daytime sleepiness (EDS) and nocturnal sleep disturbance in patients with mild to moderate Parkinson's Disease (PD).
Read the detailed description
Inclusion required an Epworth Sleepiness Scale (ESS) score greater than 10 and any subjective nocturnal sleep concern, usually insomnia. An acclimation and screening polysomnogram was performed to exclude subjects with sleepdisordered breathing. The following evening, subjects underwent another polysomnogram, followed by an evaluation with the Unified Parkinson Disease Rating Scale (UPDRS) while practically defined off ("off") PD medications, ESS (primary efficacy point), Pittsburgh Sleep Quality Inventory, and Fatigue Severity Scale. Subjects then started sodium oxybate therapy, which was titrated from 3 to 9 g per night in split doses (at bedtime and 4 hours later) across 6 weeks, and returned for subjective sleep assessments. They then returned at 12 weeks after initiating therapy for a third polysomnogram, an offmedication UPDRS evaluation, and subjective sleep assessments. Data are expressed as mean (SD).

What is being measured
The primary outcome is the main question the study is designed to answer.
Sleep and Fatigue
Sleep and Fatigue was measured using the following scales before and after sodium oxybate therapy Scales used to measure sleep and fatigue: Epworth Sleepiness Scale (ESS) where score ranges from 0-24 where 0 = no sleep problems and 24 = excessive sleep problems that should seek medical attention; Fatigue Severity Scale (FSS) where the score ranges from 9-36 where 9 = no fatigue and 36 = severe fatigue; Pittsburgh Sleep Quality Inventory (PSQI) where the score ranges from 0-21 where any score greater than 5 indicates a great sleep disturbance; 36-Item Short Form Health Survey (SF-36) where the score ranges 0-100 where 0 = the worst health status and 100 = the best health status. * Findings are reported for 28 subjects. The Full Range values reported reflect the measured minimum and maximum values.
Measured: 8 weeks
Secondary outcomes (1)
Polysomnography (PSG)
Polysomnography, also called a sleep study, is a comprehensive test used to diagnose sleep disorders. The minimum score would be 0, the maximum score would be 30. A score of 0 - 4 = normal sleep, a score of 5 - 14 = a mild level of sleep disturbance, a score of 15 - 30 is moderate level of sleep disturbance and a score of 30 is severe sleep disturbance.
Measured: 8 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing sodium oxybate in people with Parkinson Disease, run by Baylor College of Medicine.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 28 Sep 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Sleep and Fatigue (time frame: 8 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00641186, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Oct 2022; AzTrials last refreshed its copy on 8 Nov 2026.
