Overview
Brief Summary
The main objective of the study is to explore firstly, then further evaluate and confirm the efficacy between Pramipexole Sustained Release (SR) versus Pramipexole Immediate Release (IR) on nocturnal symptoms (as measured by the change from baseline to the end of the maintenance period in Parkinson's Disease Sleep Scale 2nd version (PDSS-2) score) in L-dopa+ treated patients with advanced Parkinson's disease (PD).

Eligibility Criteria
Inclusion Criteria
- •Male or female patient with advanced idiopathic Parkinson's disease (PD) confirmed by at least bradykinesia and one of the following signs: resting tremor, rigidity.
- •Diagnosed as Parkinson's disease, with at least 2 years' PD history.
- •Of age ≥ 30 years at time of diagnosis.
- •Modified Hoehn and Yahr stage of 2 to 4 at on-time.
- •They must have clinically relevant sleep disturbances (i.e. Parkinson's Disease Sleep Scale 2nd version (PDSS-2) total score ≥18 at baseline).
- •They must feel uncomfortable at night because they were unable to turn around in bed or move due to immobility (i.e. the scoring of question 9 in PDSS-2 ≥ 2, that means frequency is at least 2 to 3 days during the past week).
- •They must have early morning off (i.e. the frequency of "feeling like bodily movements are poor when you wake up?" is at least 2 to 3 days during the past week).
- •Patient must have motor fluctuations (at least 2 cumulative hours of off-time every day during waking hours, documented on a patient diary completed for 2 consecutive days before randomization visit).
- •Patients must be treated with Levodopa combined with a Dopa-Decarboxylase-inhibitor (L-Dopa+) (i.e. standard and/or controlled release Levodopa/DDC inhibitor), or with a combination of L-Dopa+ and entacapone, at an optimized dose according to investigator's judgment, this dose being stable for at least 4 weeks prior to randomization visit.
- •Patients must not have been treated with sustained release dopaminergic drug (i.e. sustained release Levodopa/Dopa-Decarboxylase (DDC) inhibitor) after supper, or any anti-PD medication after 9pm within 4 weeks prior to randomization visit.

Outcomes
Primary Outcomes
Change From Baseline to Week 18 in Parkinson's Disease Sleep Scale 2nd Version (PDSS-2) Total Score
Time Frame: Baseline and Week 18
Parkinson's disease Sleep Scale 2nd version (PDSS-2) consists of 15 questions about various sleep and nocturnal disturbances which are to be rated by the patients using one of five categories, from 0 (never) to 4 (very often). Patients were asked to rate the severity of each question based on their experience during the past week (7 days) from 0 (Never) to 4 (Very often, that meant 6 to 7 days a week). PDSS-2 total score ranges from 0 (no disturbance) to 60 (maximum nocturnal disturbance).

- Epworth Sleepiness Scale (ESS) Score (Change From Baseline)(Baseline and Week 18)
- Responder Rate for Patient Global Impression of Improvement (PGI-I)(At Week 18)
