About

Periodic Limb Movements (PLMs) during sleep in patients with Restless Legs Syndrome (RLS) have been shown to be associated with elevations in Blood Pressure (BP). Rotigotine has been shown to effectively reduce the incidence of PLMs in patients with RLS. The current study aims to demonstrate that treatment with Rotigotine could help reduce the number of nocturnal BP elevations associated with PLMs in patients with RLS.

Inclusion criteria

Subject is informed and given ample time and opportunity to think about her/his participation and give her/his written informed consent
Subject understands the investigational nature of the study and is willing and able to comply with the study requirements. Subject is willing to accept that he/she might be treated with placebo during the Treatment Period
Subject is able to apply/remove the study patch correctly
Subject is male or female, and is ≥18 and ≤75 years of age
Subject meets the diagnosis of idiopathic Restless Legs Syndrome (RLS) based on the 4 essential clinical features according to the International Restless Legs Syndrome Study Group (Allen et al,2003): 1. An urge to move legs, usually accompanied or caused by uncomfortable and unpleasant sensations in the legs (The urge to move can be present without uncomfortable sensations. Arms or other body parts can also be affected) 2. The urge to move or unpleasant sensations begin or worsen during periods of rest or inactivity, such as lying or sitting 3. The urge to move or unpleasant sensations are partially or totally relieved by movement, such as walking or stretching, at least as long as the activity continues 4. The urge to move or unpleasant sensations are worse in the evening or night than during the day or only occur in the evening or night (When symptoms are very severe, the worsening at night may not be noticeable but must have been previously present)
Subject has a score of ≥11 on the RLS-Diagnostic Index (RLS-DI) (Benes and Kohnen, 2009)
Subject has an initial response to previous dopaminergic treatment for RLS or has no previous dopaminergic treatment (ie, de novo)
The subject's Body Mass Index (BMI) is ≥18 kg/m^2 and ≤35 kg/m^2
At Baseline subject has a score of ≥15 on the IRLS (indicating moderate to severe RLS)
At Baseline subject has a score of ≥4 points on the CGI Item 1 assessment (indicating moderately ill)
At Baseline subject has a score of ≥15 PLM/h on the Periodic Limb Movements Index (PLMI) based on polysomnography (PSG) (recorded during the second night) as assessed by the investigator
Subjects are on a concomitant dose of antihypertensives that is at a stable dose for at least 4 weeks prior to Baseline and hypertension is reasonably controlled while the subject agrees to continue at this dose for the duration of the study, or subject has not received concomitant treatment with antihypertensives for at least 4 weeks prior to Baseline and does not intend to start such use during the study
