Subjects will be randomized to receive either placebo, 1.125, 2.25, 4.5, or 6.75mg/day rotigotine in a 1:1:1:1:1 (active:placebo) fashion. Approximately 600 subjects will be enrolled in this trial, participating at approximately 60 sites. The maximum duration of the trial is approximately 8 months (consisting of a 4-week Titration Period, a 6-month Maintenance Period, a 7-day Taper Period, and a 30-day Safety Follow-Up Period).
NCT00136045 ↗	Three Different Transdermal Doses of Rotigotine in Subjects With Idiopathic Restless Leg Syndrome	Completed	UCB Pharma	Phase 3	2005-05-01	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.
NCT00242008 ↗	A Trial To Assess Switching From Ropinirole, Pramipexole Or Cabergoline To The Rotigotine Transdermal System In Idiopathic Parkinson's Disease	Completed	UCB Pharma	Phase 3	2004-12-01	The purpose of this trial is to assess whether it is possible for subjects with idiopathic Parkinson's Disease to switch from ropinirole, pramipexole and cabergoline to rotigotine transdermal system (SPM 962) overnight without worsening of Parkinson's Disease symptoms. Subjects who meet eligibility criteria will be switched overnight to treatment with rotigotine transdermal patches at a dose considered equivalent to the dose of dopamine agonist that the subject is currently taking. Subjects on ropinirole or pramipexole will take their last dose at bedtime and then apply rotigotine patch(es) upon awakening the next morning. Subjects on cabergoline will apply rotigotine patches 24 hours after the final dose of cabergoline. Subjects will continue rotigotine treatment for 28 days, during which dose can be increased or decreased as needed. At the end of treatment, subjects can select to enroll in an open-label extension trial. The first subject was enrolled on 28 December 2004. The last subject was enrolled in June 2005 and the last subject visit was conducted in July 2005. This study is now closed.
NCT00243217 ↗	Rotigotine Restless Legs Syndrome Dose Finding Trial	Completed	UCB Pharma	Phase 2	2003-04-01	The objective of this trial is to demonstrate clinical efficacy of four different dosages of SPM 962 1.125 mg, 2.25 mg, 4.5 mg and 6.75 mg (corresponding to 2.5 cm2, 5 cm2, 10 cm2 and 15 cm2 patch size respectively) in RLS subjects. It is anticipated that rotigotine (SPM 936) will be more effective than placebo. The tolerability and safety of rotigotine will be assessed.
