About this study
Official title: A Multi-center, Randomized, Double-blind, Placebo-controlled, Four-arm Parallel-group Trial to Investigate the Efficacy and Safety of Three Different Transdermal Doses of Rotigotine in Subjects With Idiopathic Restless Leg Syndrome
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.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Rotigotine in people with Restless Legs Syndrome, run by UCB Pharma at 1 site in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 25 Sep 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
IRLS sum score and CGI Item 1 score severity of illness (time frame: From Baseline at the end of the Maintenance Period). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00136045, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Sep 2014.
