ListOutcomeTime frameDescription
PrimaryThe Change From Baseline to Week 6 in the Total Score of Restless Legs Syndrome Rating Scale for Severity of the International Restless Legs Syndrome Study Group (IRLS).Baseline and 6 weeks of treatment
The IRLS was a 10-item self patient's rating scale for assessing severity of restless legs syndrome symptoms with each item ranging from 0 (no symptoms) to 4 (very severe symptoms). The total IRLS score ranges from 0 (no symptoms) to 40 (worst possible symptoms).
PrimaryThe Proportion of Patients With Clinical Global Impressions -Improvement Scale (CGI-I) Assessment of "Much Improved" and "Very Much Improved"6 weeks of treatmentCGI-I: 7-point clinician rated scale ranging from 1 (very much improved) to 7 (very much worse). Improvement is defined as a score of 1 (very much improved)and 2 (much improved.
SecondaryThe Proportion of IRLS Responders6 weeks of treatmentresponders is defined as the total score in IRLS changed ≥ 50%from baseline calculated in the full analysis set population.
SecondaryThe Proportion of Patient Global Impression(PGI) Responders6 weeks of treatment
PGI was a one-question scale with 7 degrees to assess patient's overall condition, ranging from very much better to very much worse. The responder are defined as patients with their assessment of "much better" or "very much better".
SecondaryThe Proportion of Patients With Epworth Sleepiness Scale (ESS) Categorised >10week 6 of treatment
The ESS is a self-administered instrument to assess the patients likelihood of falling asleep in various activities of daily living; the maximum score is 24 indicating a very high level of daytime sleepiness and a high likelihood of falling asleep.
Secondarythe Mean Change From Baseline to Week 6 in Satisfaction of Sleep at Night of RLS-6 Rating ScalesBaseline and 6 weeks of treatmentRLS-6 rating scales comprises 6 questions Satisfaction of sleep is one of the 6 questions. The patient should give a rate between 0 (none/Not at all) to 10 (very severe) for the satisfaction of sleep.
SecondaryThe Mean Change From Baseline in the Severity of RLS at Time of Falling Sleep of RLS-6 Rating Scales.Baseline and 6 weeks of treatment
RLS-6 rating scales comprises 6 questions. The severity of RLS at time of falling sleep is one of the 6 questions. The patient should give a rate between 0 (none/Not at all) to 10 (very severe) for the severity of RLS at time of falling sleep
SecondaryThe Mean Change From Baseline in the Severity of RLS During the Night of RLS-6 Rating Scales.Baseline and 6 weeks of treatment
RLS-6 rating scales comprises 6 questions. The severity of RLS during the night is one of the 6 questions. The patient should give a rate between 0 ("none/Not at all") to 10 ("very severe") for the severity of RLS during the night.
SecondaryThe Mean Change From Baseline in the Severity of RLS During the Rest at Day of RLS-6 Rating Scales.Baseline and 6 weeks of treatment
RLS-6 rating scales comprises 6 questions. The severity of RLS during the test at day is one of the 6 questions. The patient should give a rate between 0 ("none/Not at all") to 10 ("very severe") for the severity of RLS during the rest at day.
SecondaryThe Mean Change From Baseline in the Severity of RLS During the Activities at Day of RLS-6 Rating ScaleBaseline and 6 weeks of treatment
RLS-6 rating scales comprises 6 questions. The severity of RLS during the activities at day is one of the 6 questions. The patient should give a rate between 0 ("none/Not at all") to 10 ("very severe") for the severity of RLS during the activity at day.
