• 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)

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: 2 milligram/24 hours rotigotine; Subjects randomized to this arm will be initiated on 1 milligram (mg)/24 hours (h) rotigotine and up-titrated to a maximum of 2 mg/24 h rotigotine, which is the assigned dose level throughout the 12-week Maintenance Period.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline to the End of the Maintenance Period in International Restless Legs Rating Scale (IRLS) Sum Score	The IRLS consisted of 10 questions, each scored using a 5-point scale ranging from 0=not present to 4=very severe. The IRLS sum score was calculated by summing up the single scores of all applicable questions, i.e., the total sum score ranged from 0 (no RLS symptoms present) to 40 (maximum severity in all symptoms). A score between 31 and 40, indicates very severe RLS. A score between 21 and 30 indicates severe RLS. A score between 11 and 20 indicates moderate RLS. A score between 1 and 10 indicates mild RLS and a score of 0 means no RLS. A negative change from Baseline indicates improvement.	From Baseline to the end of the Maintenance Period (Day 106)
Change From Baseline in Clinical Global Impressions (CGI) Item 1 to the End of the Maintenance Period	The Clinical Global Impressions Item 1 (Severity of Illness) score ranges from 0 to 7 as follows: 0=not assessed, 1=normal, not ill at all, 2=borderline ill, 3=mildly ill, 4=moderately ill, 5=markedly ill, 6=severely ill, 7=among the most extremely ill. The CGI Item 1 was completed during an interview between the participant and the investigator or designee. A negative change from Baseline indicates improvement.	From Baseline to the end of the Maintenance Period (Day 106)
Percentage of Participants With Treatment-emergent Adverse Events (TEAEs)	TEAEs were defined as events that started during the Treatment Period or within 30 days following the end of the Treatment Period (i.e., on or after the date of first patch application and within 30 days following the date of last patch removal + 1 day), or those events where the intensity worsened within this time frame.	From Baseline to Safety Follow-Up (up to Week 20)
Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) Leading to Withdrawals	TEAEs were defined as events that started during the Treatment Period or within 30 days following the end of the Treatment Period (i.e., on or after the date of first patch application and within 30 days following the date of last patch removal + 1 day), or those events where the intensity worsened within this time frame.	From Baseline to Safety Follow-Up (up to Week 20)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Restless Legs-6 Rating Scales (RLS-6) to the End of the Maintenance Period	The RLS-6 Rating Scales was designed to assess the severity of RLS and consisted of 6 subscales. The subscales assessed severity of symptoms at the following times of the day/evening: falling asleep, during the night, during the day at rest, and during the day when engaged in daytime activities. In addition, the subscales assessed satisfaction with sleep and severity of daytime tiredness/sleepiness. Scores for each of the 6 subscales ranged from 0 (completely satisfied) to 10 (completely dissatisfied). The change from baseline was derived for each of the subscales and reported in this outcome measure. A negative change from Baseline indicates improvement.	From Baseline to the end of the Maintenance Period (Day 106)

Plan for Individual participant data (IPD)

• Plan to Share Individual Participant Data (IPD)?: YES
• IPD Plan Description: Data from this trial may be requested by qualified researchers six months after product approval in the US and/or Europe, or global development is discontinued, and 18 months after trial completion. Investigators may request access to anonymized individual patient-level data and redacted trial documents which may include: analysis-ready datasets, study protocol, annotated case report form, statistical analysis plan, dataset specifications, and clinical study report. Prior to use of the data, proposals need to be approved by an independent review panel at www.Vivli.org and a signed data sharing agreement will need to be executed. All documents are available in English only, for a prespecified time, typically 12 months, on a password protected portal. This plan may change if the risk of re-identifying trial participants is determined to be too high after the trial is completed; in this case and to protect participants, individual patient-level data would not be made available.
