Brief summary

Ropinirole has shown to improve mood in depressed patients as well as to improve the symptoms of Restless Legs Syndrome. Up to 40% of RLS patients suffer from mild depression, therefore it would be important for decisions no therapy to know whether a drug could improve both depressive and RLS symptoms.

Inclusion criteria

* diagnosis of idiopathic Restless Legs Syndrome, confirmed by a score of at least 11 on the RLS Diagnostic Index * certain severity of symptoms (at least score of 15 on the International Restless Legs Score (IRLS) * Have had RLS symptoms for at least 15 nights in the last four weeks. * \< 6 hours of sleep in nights with RLS symptoms * MADRS (depression rating scale) score of at least 12 (= borderline to depression) at baseline

Exclusion criteria

* any other sleep disorder that might interfere with the RLS symptoms or sleep (e.g. sleep apnea disorder, narcolepsy) * Secondary RLS due to diagnosis of renal insufficiency, polyneuropathy, pregnancy (see below), iron deficiency anemia * Any significant psychiatric disorders (e.g. schizophrenia, bipolar disorder); depression which by judgement of the investigator is caused by RLS, is not an exclusion criterion. * Current or past suicidality * medication known to trigger/aggravate/ cause or interfere with RLS symptoms (e.g. most antidepressants, lithium, neuroleptics, opioids, carbidopa, clonidine, antihistamines, anticonvulsants etc.). * daytime RLS symptoms which require treatment (daytime: 10 a.m. until 6 p.m.). * concomitant movement disorders (e.g. Parkinson's Disease, dyskinesia, dystonia). * medical conditions with symptoms which could affect assessments of efficacy (e.g. diabetes, rheumatoid arthritis, fibromyalgia syndrome, cancer etc.). * Subjects taking any medication known to induce drowsiness or to affect sleep. * Subjects who are pregnant, lactating or of childbearing potential. Women of childbearing potential must use adequate contraception * clinically significant or unstable medical conditions (e.g. severe heart disease, severe liver or kidney disease etc.). * pain syndromes, caused by other disorders than RLS * excessive caffeine intake * diastolic blood pressure \>110mmHg or \<50mmHg or systolic blood pressure \>180mmHg or \<90mmHg at baseline. * Withdrawal, introduction, or change in dose of hormone replacement therapy (HRT) or the oral contraceptive pill (OCP) and/or certain drugs which are known to interact with ropinirole (e.g. ciprofloxacin, cimetidine, tobacco, omeprazole).

Questions are scored 0-6. Total Score 0-60, the higher the score indicates the most severely depressed patients.

Time frame: Baseline and Week 12

Population: Modified Intent to Treat (mITT): All treated patients with MADRS score at baseline and post baseline (i.e., at visit 4 and/or 5).

International Restless Legs Scale for Severity (IRLS)is a series of 10 questions which rate severity from 0-4 points for various questions and total score ranks: Very severe=31-40 points, Severe=21-30 points, Moderate=11-20 points, and Mild=1-10 points, None=0 points

Percentage of Participants With at Least Moderate Depression (HAM-D >= 15) at Baseline and in Week 12

The Hamilton Rating Scale for Depression contains 17 questions which detect change and measure illness severity. Individual items are rated on a scale of 0-4, 0-3, and 0-2 with total HAMD score range from 0 (not ill) to 54 (severely ill).

Time frame: Baseline and Week 12

Percentage of Participants With Much Improved or Very Much Improved on the Clinical Global Impression-Global Improvement Scale After 1, 4 and 12 Weeks

The CGI-I assesses the investigator's impression of the patient's current illness. The time span is the week before the rating and the score range: 1-very much improved, 2-much improved, 3-minimally improved, 4-no change, 5- minimally worse, 6-much worse, to 7-very much worse.

Time frame: Week 1, Week 4, Week 12
