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).
Drug: sodium oxybate
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||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
Primary Outcome Measures:
- To evaluate the safety and tolerability of Xyrem (sodium oxybate) oral solution at nightly doses of 4.5 to 9.0 grams in patients with Parkinson's Disease [ Time Frame: 8 weeks ] [ Designated as safety issue: Yes ]
- To evaluate the possible efficacy of Xyrem in the treatment of the sleep disturbances and EDS common in Parkinsonian patients. [ Time Frame: 8 weeks ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- To determine if Xyrem treatment improves daytime motor symptoms and the overall quality of life in patients with mild to moderate PD. [ Time Frame: 8 weeks ] [ Designated as safety issue: Yes ]
