No
- at Week -1 (at the screening visit)

- at Week -1 (at the screening visit)
- Patients with signs of primary RLS (Patients who have developed RLS symptoms since kidney function was normal)
Inclusion and exclusion criteria
Inclusion criteria:
- at Week -1 (at the screening visit)
- Patients who are diagnosed with symptomatic restless legs syndrome associated with Chronic kidney disease (CKD) managed with haemodialysis (including haemofiltration and haemodiafiltration). RLS are diagnosed based on the International RLS Study Group’s (IRLSSG) Diagnostic Criteria.
- Patients with chronic kidney disease (CKD) on haemodialysis (including haemofiltration and haemodiafiltration) for at least 3 months prior to the screening period with and receiving an adequate haemodialysis prescription (i.e. single-pool Kt/V >1.0. Shinzato calculating formula [Shinzato, 1994] using in Japanese Society for Dialysis Therapy will be used.)
- Patients aged ≥18 years and <80 years.
- Patients who have had RLS symptoms for 20 days or more on or after 28 days before the start of the screening period. However, patients who have been receiving drug therapy for RLS before the start of the screening period do not apply to this criterion when meeting the conditions below: The patient's drug therapy (excluding Anxiolytics and Hypnotics and sedatives medication) for RLS can be discontinued at the time of starting the screening period. For RLS symptoms in the subject was considered to have continued for 20 days or more on or after 28 days before the start of the drug treatment for RLS.
- QTc criteria (QTc [b or f], mechanical or manual reread, male or female): Patients with QTc <450 msec or <480 msec for patients with bundle branch block (BBB) -values based on either single electrocardiogram (ECG) values or triplicate ECG averaged QTc values obtained over a brief recording period.
