Summary
The primary objective of this trial is to demonstrate that rotigotine (SPM 936) is
efficacious in subjects with idiopathic restless leg syndrome (RLS). Additional objectives
are to investigate the safety and tolerability of rotigotine.
The primary variables are the absolute change from Baseline in the International Restless
Legs Severity Scale (IRLS) sum score and Clinical Global Impression-Global Improvement (CGI)
Item 1 (severity of illness) score at the end of the Maintenance Period.
Subjects will be randomized to receive either placebo, 2.25, 4.5 or 6.75 mg/day rotigotine in
a 1:1:1:1 (active:placebo) fashion. Approximately 450 subjects will be enrolled in this
trial, participating at approximately 50 sites. The maximum duration of the trial is
approximately 8 months (3-week Titration Period, 6-month Maintenance Period, 7-day Taper
Period, and 30-day Safety Follow-Up Period). Subjects who complete the 6-month Maintenance
Period will be eligible to participate in an open-label extension trial. Subjects who do not
complete the 6-month Maintenance Period or who choose not to participate in the open-label
extension trial will complete a 3-day Safety Follow-Up Period. Two different patch sizes will
be used (5 and 10 cm2). Active patches will contain either 2.25mg (5cm2) or 4.5mg (10cm2) of
rotigotine.
