Objective: This double-blind, placebo-controlled, interventional trial was conducted to investigate the effects of rotigotine patch on periodic limb movement (PLM)-associated nocturnal systolic blood pressure (SBP) elevations.

Methods: Patients with moderate to severe restless legs syndrome (RLS) were randomized to rotigotine (optimal dose [1-3 mg/24 h]) or placebo. Continuous beat-to-beat blood pressure (BP) assessments were performed during polysomnography at baseline and at the end of 4-week maintenance.

Aim: The aim of this study is to assess the effect of switching to rotigotine transdermal patch on severity of restless legs syndrome (RLS) in patients who experienced acute augmentation with previous oral dopaminergics.

Methods: In this 13-month observational study, adults with moderate-to-severe RLS and augmentation were switched to rotigotine per the physician's independent decision. Assessments included Clinical Global Impression severity score (CGI-1); (primary), treatment regimen for switching (secondary), RLS-6, International RLS Study Group Rating Scale (IRLS), and augmentation severity rating scale (ASRS).

Background: Restless legs syndrome (RLS) has been associated with insomnia, decreased quality of life, and increased morbidity and mortality in end-stage renal disease. This randomized controlled trial investigated effects of rotigotine in patients with RLS and end-stage renal disease.

Study Design: Double-blind placebo-controlled study.

Objective: A new and unique methodology was developed to evaluate the association between periodic limb movements (PLMs) and nocturnal blood pressure (BP) excursions in patients with restless legs syndrome (RLS).

Methods: All data were collected at baseline of the ENCORE (Effects of Neupro on Cardiovascular Observations in Patients with Restless Legs Syndrome) study, a placebo-controlled polysomnographic study of rotigotine in patients with idiopathic RLS. Continuous beat-by-beat BP and heart rate assessments were performed during a full night of polysomnography.

Background: The SP790 study (ClinicalTrials.gov, NCT00136045) showed benefits of rotigotine over placebo in improving symptom severity of restless legs syndrome (RLS), also known as Willis-Ekbom disease, on the International Restless Legs Syndrome Study Group rating scale (IRLS), Clinical Global Impression item 1 (CGI-1), RLS 6-item questionnaire (RLS-6), and the RLS-quality of life questionnaire (RLS-QoL) in patients with moderate to severe idiopathic RLS. To provide clinical context for the IRLS and to guide the choice of assessment scales for RLS studies, our post hoc analysis of SP790 data evaluated associations between the IRLS and the CGI-1, IRLS and RLS-6, and the IRLS and RLS-QoL.

Objective: We aimed to assess effectiveness and tolerability of rotigotine in patients with moderate to severe idiopathic restless legs syndrome (RLS) under daily practice conditions in Germany.

Methods: In this 3-month noninterventional study, effectiveness was assessed using RLS-6 (primary variables were symptom severity when falling asleep [item 2] and during the night [item 3]). Data were collected at baseline and at the end of treatment.

Objective: This post-hoc analysis of a prospective open-label study investigated patients with restless legs syndrome (RLS) taking approved dosages (1, 2 or 3 mg/24 h) of rotigotine transdermal patch for up to 5 years.

Research Design And Methods: Following 6 weeks' double-blind treatment, patients with moderate-to-severe RLS received open-label rotigotine titrated to optimal dosage.

Main Outcome Measures: Safety was assessed by adverse events (AEs) and efficacy was assessed by the International Restless Legs Syndrome Study Group Rating Scale (IRLS).

Background: Immobilisation, blood loss, sleep deficiency, and (concomitant) medications during perioperative periods might lead to acute exacerbation of symptoms in patients with the restless legs syndrome (RLS). Continuous transdermal delivery of the dopamine agonist rotigotine provides stable plasma levels over 24 h and may provide RLS patients with a feasible treatment option for perioperative situations. To assess the feasibility of use of rotigotine transdermal patch for the perioperative management of moderate to severe RLS, long-term data of an open-label extension of a rotigotine dose-finding study were retrospectively reviewed.

Objective: To assess the risk of augmentation under treatment with the transdermally delivered dopamine agonist rotigotine for restless legs syndrome (RLS).

Methods: Experts in RLS augmentation retrospectively reviewed data from two double-blind, placebo-controlled 6-month trials (745 rotigotine and 214 placebo subjects, NCT00136045 and NCT00135993) and from two open-label 1-year trials (620 rotigotine subjects, NCT00498108 and NCT00263068). All study visits were systematically evaluated applying the Max Planck Institute (MPI) criteria for the diagnosis of both augmentation and clinically relevant augmentation.

Background: Safety and efficacy of non-ergot dopamine agonists for the treatment of idiopathic restless legs syndrome have been shown in short-term trials. We did a prospective open-label extension of a 6-week, double-blind randomised trial to assess the safety, tolerability, and efficacy of rotigotine transdermal patch for up to 5 years in patients with restless legs syndrome.

Methods: Patients (aged 18-75 years) with moderate-to-severe idiopathic restless legs syndrome were treated with once-daily rotigotine transdermal patch in 33 centres in Austria, Germany, and Spain between July 31, 2003, and April 15, 2009.

Background: Rotigotine is a unique dopamine agonist with activity across D1 through D5 receptors as well as select adrenergic and serotonergic sites. This study reports the 2-year follow-up safety and efficacy data of an ongoing open-label multicenter extension study (NCT00498186) of transdermal rotigotine in patients with moderate to severe restless legs syndrome (RLS).

Methods: Patients received a once-daily patch application of an individually optimized dose of rotigotine between 0.

Objective: To assess the efficacy of rotigotine transdermal patch in subjects with moderate to severe idiopathic restless legs syndrome (RLS) and periodic limb movement (PLM) in sleep in a double-blind, randomized, placebo-controlled, multicenter study (NCT00275236).

Methods: Sixty-seven (46 rotigotine, 21 placebo) subjects applied rotigotine (maximum 3mg/24h) or placebo patches once-daily during a 4-week maintenance period; efficacy evaluations used polysomnographic measures and clinician/patient ratings.

Results: Mean PLM index (PLMI; PLM/h time in bed) decreased more with rotigotine (50.

This randomized, double-blinded, placebo-controlled trial (NCT00135993) assessed efficacy and safety of the dopamine agonist rotigotine in the treatment of idiopathic restless legs syndrome (RLS) over a 6-month maintenance period. A total of 505 eligible participants with moderate to severe RLS (IRLS sum score >or= 15) were randomly assigned to five groups to receive either placebo or rotigotine (0.5, 1, 2, or 3 mg/24 hr) delivered by once-daily transdermal patch (fixed-dose regimen).
