Primary Outcome Measures
NameTimeMethod
Effect of pimavanserin on sleep fragmentation6 weeks

Number of arousals and the arousal index (arousals per hour of sleep) measured on polysomnography

Secondary Outcome Measures
NameTimeMethod
Effect of pimavanserin on sleep efficiency6 weeks

Sleep Efficiency Index in percent is the ratio of total sleep time (based on polysomnography recordings) to time in bed

Effect of pimavanserin on subjective measures of sleep6 weeks

PDSS-2 (Parkinson's Disease Sleep Scale Version 2) total score ranges from 0 (no disturbance) to 60 (maximum nocturnal disturbance). Scores \> 18 are considered as relevant sleep disturbances

Effect of pimavanserin on REM (Rapid Eye Movements) sleep behavior disorder6 weeks

Presence fo REM sleep without atonia (RWA) on polysomnograophy

Effect of pimavanserin on time in each sleep stage6 weeks

Time in each sleep stage as measured on polysomnography

Effect of pimavanserin on subjective measure of REM Sleep behavior disorder6 weeks

RBDSQ (REM (Rapid Eye Movements) Sleep Behavior Disorder Screening Questionnaire to assess the most prominent clinical features of RBD. It is a 10-item, patient self-rating instrument with short questions to be answered by either 'yes' or 'no'.

Effect of pimavanserin on sleep latency6 weeks

Time to first epoch on polysomnography

Effect of pimavanserin on total sleep time6 weeks

Total sleep time measured on polysomnography

Effect of pimavanserin on subjective measures of fatigue6 weeks

PFS-16 (Parkinson's disease Fatigue Scale): 16-item scale with the following scoring for each item: strong disagree -1, disagree - 2, neither agree or disagree - 3, agree - 4, strongly agree - 5; with overall score of ≥8 indicates the presence of significant fatigue.
