Study Arms:
- Rotigotine (Type: EXPERIMENTAL): - Titration Period: Weekly titration to the subject's optimal dose of Rotigotine between 2 mg/24 h and 8 mg/24 h. In case of intolerable Adverse Events (AEs) one back-titration is allowed during the Titration Period.~Duration of the Titration Period: Between 1 week and 5 weeks.~- Maintenance Period: Starts once subject reached either optimal or maximal dose of Rotigotine. Subjects receive stable dose of Rotigotine throughout the Maintenance Period. No back-titration is allowed during the Maintenance Period.~Duration of the Maintenance Period: Between 3 weeks and 7 weeks.

Based on this trial design, predict the completion outcome and termination type (if applicable).
