Participant Flow

Recruitment Details

Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
The study was conducted in Europe and USA. Recruitment was planned to continue until approximately 64 patients were randomized in the study. Subjects were randomized in a 1:1 ratio to either Rotigotine or Placebo. To achieve this, approximately 28 investigational sites were planned to participate in this hypothesis-generating pilot study.

Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
The Participant Flow population refers to the Randomized Set (RS). The RS includes all subjects who were randomized.

Reporting Groups

	Description
Placebo	Placebo Transdermal Patches Placebo: Placebo patches matched the size of active patches 20 cm^2, 30 cm^2, or 40 cm^2 and contained Placebo. Application of Placebo patches started at the Baseline Visit. Placebo patches were administered once daily starting with the equivalent of 4 mg / 24 h. Doses were then up-titrated in weekly equivalents to 2 mg / 24 h until either optimal dose or maximum dose was reached. The maximum dose was the equivalent to 16 mg / 24 h. The duration of the Titration Period varied from 1 to 7 weeks. The Maintenance Period lasted 12 weeks ± 5 days. During the De-Escalation Period, the dose of Placebo will be decreased by the equivalent to 2 mg / 24 h every other day. The De-Escalation Period might have lasted up to 12 days.
Rotigotine	Rotigotine Transdermal Patches Rotigotine: Patches contained 4 mg / 24 h (20 cm^2), 6 mg/ 24 h (30 cm^2), or 8 mg /24 h (40 cm^2) of Rotigotine. Application of study medication started at the Baseline Visit. Rotigotine was administered once daily starting at 4 mg / 24 h. Doses were then up-titrated in weekly increments of 2 mg / 24 h until optimal or maximum dose (16 mg / 24 h) was reached and the Maintenance Period could be started. The duration of the Titration Period varied from 1 to 7 weeks ± 3 days. The Maintenance Period lasted 12 weeks ± 5 days. Thereafter, during the De-Escalation Period, the dose of study medication was decreased by 2 mg / 24 h every other day. The De-Escalation Period might have lasted up to 12 days.
