Primary Outcome Measures :
- Change From Baseline in International Restless Legs Syndrome (IRLS) Total Score at 6 Weeks [ Time Frame: Week 6 - change from baseline ]The International Restless Legs Syndrome Study Group (IRLSSG) proposes classification of severity based on the total score on the IRLS (0-10, mild; 11-20, moderate; 21-30, severe; 31-40, very severe). A decrease in the score of the IRLS by 10 or more points corresponds to the improvement of severity by one rank and has clinical importance. Therefore, the primary endpoint in the double-blind period was set as a decrease by 10 or more points in the mean change on the total score of the IRLS from the baseline to Visit 5 (last observation day in the double-blind period) at all doses of 0.25 mg, 0.5 mg, and 0.75 mg/day of pramipexole.
Secondary Outcome Measures :
- IRLS Responder [ Time Frame: baseline to week 6 ]The percentage of patients with 50 % or more reduction of IRLS (The measure means the percentage of high responder on the trial medications)
- Change From Baseline in Pittsburgh Sleep Quality Index (PSQI) Total Score at 6 Weeks [ Time Frame: Week 6 - change from baseline ]PSQI developed to evaluate the quality of sleep is a self-recording questionnaire consisting of 18 questions focused on 7 factors such as sleep quality, sleep period time, sleep latency, sleep efficiency, sleep difficulty, use of hypnotics, and hindrance to activities of daily living due to daytime sleepiness. Each score (0-3 points) in the respective factors was added to calculate the total score (0-21 points). Rating scale scored from 0 (best sleep) to 21 (worst sleep).
- Change From Baseline in Japanese Version of the Epworth Sleepiness Scale (JESS) Total Score at 6 Weeks [ Time Frame: Week 6 - change from baseline ]ESS is a self-recording scale used to evaluate sleepiness experienced in daily activities and it consists of 8 items focused on specific situations such as reading books and watching television. Each score (0-3 points) to 8 questions was added simply to calculate the total ESS score. A Japanese translation of the ESS (a provisional version provided by the Japanese Respiratory Society) used so far had not been prepared through the international scale development and validation process, but the version prepared through this process was published at the 31st meeting of the Japanese Society of Sleep Research. The questions in JESS had been discussed with the original author of the ESS and their measurement concepts had been confirmed. The JESS is the Japanese version of ESS prepared through the international scale development and validation process. Rating scale scored from 0 (no daytime sleep) to 24 (worst daytime sleep)
- Clinical Global Impression Global Improvement (CGI-I) Responder [ Time Frame: baseline to week 6 ]CGI is extensively used for risk-benefit evaluation (efficacy) of drug therapies. The CGI evaluates the severity and improvement in 7 ranks. It also evaluates the therapeutic effect and side effects in 4 ranks, separately. Rating scale from 1 (very much improved) to 7 (very much worse). The percentage of patients who were evaluated as 1(very much improved) or 2(much improved) by the investigator were considered responders.
- Patient Global Impression (PGI) Responder [ Time Frame: baseline to week 6 ]PGI is used to evaluate a global impression by patients themselves in 7 ranks. Rating scale from 1 (very much better) to 7 (very much worse). The percentage of patients where the patient evaluated himself/herself as 1(very much better) or 2(much better)were considered responders.
- Clinically Significant Abnormalities in Vital Signs (Blood Pressure and Pulse Rate in Both Supine and Standing Positions), ECG, Laboratory Tests - Double Blind Period. [ Time Frame: baseline to 6 weeks ]
- Change From Baseline in International Restless Legs Syndrome (IRLS) Total Score at 52 Weeks for Open-Label Period [ Time Frame: Week 52 - change from baseline ]The International Restless Legs Syndrome Study Group (IRLSSG) proposes classification of severity based on the total score on the IRLS (0-10, mild; 11-20, moderate; 21-30, severe; 31-40, very severe).
- IRLS Responder for Open-label Period [ Time Frame: baseline to week 52 ]The percentage of patients with 50 % or more reduction of IRLS (The measure means the percentage of high responder on the trial medications)

- Possible Augmentation in RLS Symptoms at 52 Weeks for Open-Label Period [ Time Frame: baseline to week 52 ]Possible augmentation defined as persistence of a state in which RLS symptoms begin to occur 2 hours earlier than the usual time zone for 5 days or more a week
