About

The purpose of this study is to demonstrate the efficacy of rotigotine against placebo in adolescent subjects with idiopathic Restless Legs Syndrome (RLS) over a 12-week maintenance period and to investigate the safety and tolerability of rotigotine in adolescent subjects with idiopathic RLS.

Enrollment: 23 patients

Ages: 13 to 17 years old

Volunteers: No Healthy Volunteers

• At Visit 1/Screening, subject has symptomatic orthostatic hypotension with a decrease of blood pressure (BP) from supine to standing position of >=20 mmHg in systolic blood pressure (SBP) or of >=10 mmHg in diastolic
• Subject has secondary Restless Legs Syndrome (RLS) (eg, due to renal insufficiency [uremia], iron deficiency, or rheumatoid arthritis)
• Subject has a lifetime history of suicide attempts (including actual attempt, interrupted attempt, or aborted attempt), or had suicidal ideation in the past 6 months as indicated by a positive response ("Yes") to either Question 4 or Question 5 of the Columbia-Suicide Severity Rating Scale (C-SSRS) at Screening (Visit 1)
