Effect of Safinamide on Sleep Quality in Patients With Parkinson's Disease
A Prospective, Open Label, Single Arm, Clinical Study to Evaluate the Effect of Safinamide on Sleep Quality and Polysomnographic Parameters in Patients With Parkinson's Disease: the Safe Sleep Study
Study Overview
Status
Intervention / Treatment
Detailed Description
Adult patients affected by PD and suffering from motor fluctuations will be screened for participation.
If the inclusion and exclusion criteria are met, the participant will enter in the baseline assessment phase and undergo 1 night baseline PSG and 1 week baseline actigraphy. The patient will then start the treatment with 50 mg/day of Safinamide per os for 2 weeks (escalation phase). Then, safinamide will be increased up to 100 mg/day and, if tolerated, the treatment will last for 10 weeks (maintenance phase). At week 12 (end of treatment), the questionnaires, actigraphy and PSG will be repeated. A safety follow-up visit is scheduled 4 weeks after study treatment completion.
The treatment will be continued thereafter in all patients if medically indicated.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Effect of safinamide on overall sleep quality
Time Frame: 12 weeks
|
To measure the change in PDSS-2 (Parkinson's Disease Sleep Scale Version 2) score and the changes in sleep maintenance (=total sleep time/partial sleep time) and sleep efficiency (=total sleep time/ time in bed) scores measured by polysomnography (PSG).
PDSS-2 total score ranges from 0 (no disturbance) to 60 (maximum nocturnal disturbance).
Scores > 18 are considered as relevant sleep disturbances.
|
12 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Effect of safinamide on objective PSG sleep characterization
Time Frame: 12 weeks
|
To determine neurophysiological sleep parameters from PSG recording
|
12 weeks
|
Effect of safinamide on subjective sleep quality and sleepiness
Time Frame: 12 weeks
|
To measure the change in subjective sleep quality as measured by PDSS-2 subscores and by the electronic diary "Sleep Fit app", and in daytime sleepiness as measured by ESS (Epworth sleepiness scale) score.
PDSS-2 total score ranges from 0 (no disturbance) to 60 (maximum nocturnal disturbance).
Scores > 18 are considered as relevant sleep disturbances.
ESS score ranges from 0 to 24.
Scores > 10 suggest relevant daytime sleepiness.
|
12 weeks
|
Effect of safinamide on objective motor activity
Time Frame: 12 weeks
|
To determine the change in motor activity as measured by a specific objective measure of bradykinesia (FitTest) in the electronic diary "Sleep Fit app".
|
12 weeks
|
Effect of safinamide on subjective motor activity
Time Frame: 12 weeks
|
To measure the change in motor activity as measured by UPDRS (Unified Parkinson's Disease Rating Scale).
Higher UPDRS score indicates more severe impairment of non-motor and motor activities.
|
12 weeks
|
Effect of safinamide on objective sleep parameters and motor symptoms
Time Frame: 12 weeks
|
To measure the change in sleep parameters and motor activity during the day and the night as measured by actigraphy.
|
12 weeks
|
Effect of safinamide on non-motor symptoms
Time Frame: 12 weeks
|
To measure the change in depressive symptoms as measured by (BDI-II) Beck Depression Inventory and SAS (Starkstein Apathy Scale).
Total BDI-II score ranges from 0 to 63 with higher total score indicating more severe depressive symptoms.
Total SAS score ranges from 0 to 42 with higher scores indicating more severe apathy.
|
12 weeks
|
Effect of safinamide on quality of life
Time Frame: 12 weeks
|
To measure the change in quality of life as measured by PDQ-39 (Parkinson's Disease Questionnaire-39).
PDQ-39 is scored on a scale of 0 to 100, with lower scores indicating better health and high scores more severe symptoms.
