SUMMARY 
This is a Phase 3, remote, double-blind, randomized, adaptive, placebo-controlled study of fixed 
dose administration of rotigotine transdermal system in adolescent subjects, 13 to 17 years of 
age, with idiopathic Restless Legs Syndrome (RLS). Subjects will be randomized to 1 of 
3 treatment groups: placebo, 2mg/24h rotigotine, or 3mg/24h rotigotine.  
The total study duration per subject will be up to 24 weeks including a 4-week Screening Period, 
a 3-week Titration Period, 12-week Maintenance Period, a Taper Period of 4 days (with 
de-escalation by 1 dose step every 2 days), and a 30-day Safety Follow-Up Period (for subjects 
not participating in the open-label, long-term follow-up study). The end of the study is defined as 
the last visit of the last subject in the study. 
A total of 138 subjects are planned to be randomized during the study. A single remote site in the 
USA is planned to be included in the study. This model integrates telemedicine technology into 
the clinical research process and supports management of research activities, including data 
collection.  
The primary objective of this study is to demonstrate the efficacy of rotigotine against placebo in 
adolescent subjects with idiopathic RLS over a 12-week Maintenance Period. The secondary 
objectives are to investigate the efficacy, safety, and tolerability of rotigotine in adolescent 
subjects. 
The co-primary efficacy variables are change from Baseline to the end of the Maintenance 
Period in International Restless Legs Rating Scale (IRLS) sum score and change from Baseline 
to the end of the Maintenance Period in Clinical Global Impressions (CGI) Item 1 score. 
Other efficacy variables are change from Baseline by visit in IRLS sum score and 
Restless Legs-6 Rating Scales (RLS-6). 
Safety variables are adverse events (AEs), withdrawals due to AEs, physical and neurological 
examination findings, changes from Baseline in 12-lead electrocardiograms (ECGs), vital signs, 
laboratory data, hormone status, body weight, height, body mass index (BMI), and Modified 
Minnesota Impulsive Disorder Interview (mMIDI).

INTRODUCTION 
Restless Legs Syndrome, also known as Willis-Ekbom disease, is a common pediatric neurologic 
condition affecting 2% to 4% of school-aged children and adolescents, with about 25% to 50% 
of pediatric cases having moderate-to-severe symptoms. Restless Legs Syndrome has a 
significant impact on sleep, mood, cognition, and function, particularly sleep disturbance. 
Impairment is often manifested in behavioral and educational domains (Pichietti et al, 2013). 
Genetic factors, dopamine dysfunction, and low-iron stores may play a role in the 
pathophysiology of RLS (Simakajornboon et al, 2009). Current evidence supports relative iron 
deficiency and renal failure as potential aggravating factors for pediatric RLS. Periodic limb 
movements in sleep and a family history of RLS among first-degree relatives are supportive of 
pediatric RLS (Pichietti et al, 2013). 
The pediatric RLS diagnostic criteria were published in 2003 based on the consensus at a 
National Institutes of Health workshop (2002) sponsored in part by the International RLS Study 
Group. These diagnostic criteria were updated in 2013 by the International RLS Study Group

(Picchietti et al, 2013). Ruling out RLS mimics was integrated as an essential element for RLS 
diagnosis. 
Dopaminergic agents are the first-choice treatment for RLS in adults; however, to date, no 
treatment for RLS has been approved for children. Small published reports suggest that 
dopamine agonists are effective in the management of RLS in children (Simakajornboon et al, 
2009; Cortese et al, 2009; Muhle et al, 2008; Mohri et al, 2008; Konofal et al, 2005; 
Guilleminault et al, 2003).  
The investigational medicinal product (IMP) is a transdermal formulation of the dopamine 
agonist rotigotine. The patch is applied to the skin and provides constant plasma concentrations. 
It was first approved by the European regulatory authorities for use in patients with Parkinson’s 
disease in March 2006, and by the US Food and Drug Administration (FDA) in May 2007. 
Rotigotine transdermal system was approved by the FDA as a treatment for adult patients with 
RLS in April 2012. 
The tolerability of rotigotine transdermal system appears to be within the range of what is known 
and expected from other dopamine agonists, except for application site reactions, which appear 
to be mild to moderate in the majority of cases (Perez-Lloret et al, 2013). 
UCB has completed a Phase 2 pharmacokinetic (PK)/pharmacodynamic (PD) study in adolescent 
subjects 13 to 17 years of age, which showed a PK profile similar to that in adult subjects. 
Although the study was open-label and the sample size was small, the efficacy of rotigotine 
transdermal system in adolescent subjects also appeared similar to efficacy in adults. 
Improvements were observed in most efficacy parameters, including the IRLS, CGI Items 1 
through 3, and RLS-6, indicating improvements in RLS symptoms and sleep. The purpose of this 
study is to further investigate the efficacy, safety, and tolerability of rotigotine in adolescent 
subjects 13 to 17 years of age. 
A remote study model will be used to conduct this study. This model integrates telemedicine 
technology into the clinical research process and supports management of research activities, 
including data collection. As part of this model, study visits are completed using the unique 
technology platform called Science 37 Platform, or PLATFORM, which is the backbone of the 
studies conducted via this model. PLATFORM is the software interface that connects 
subjects/legal representatives to their investigators/study teams through a study-issued 
smartphone. This technology will be used in combination with visits from mobile study 
personnel to subjects’/legal representatives’ homes.

STUDY DESIGN 
5.1 
Study description 
This is a Phase 3, remote, double-blind, randomized, adaptive placebo-controlled study of fixed 
dose administration of the rotigotine transdermal system. The study will be conducted in 
adolescent subjects, 13 to17 years of age, with idiopathic RLS. Subjects will be randomized to 
1 of 3 treatment groups: placebo, 2mg/24h rotigotine, or 3mg/24h rotigotine. 
The study will be conducted using the remote study model, which uses telemedicine technology 
(ie, PLATFORM, see Section 2 for an overview) for interactions between the investigator/study 
staff and study subjects/legal representatives. Mobile study personnel will visit subjects’/legal 
representatives’ homes to complete certain study procedures (eg, neurological exams, physical 
exams, ECGs, lab collections, and vital signs). 
The study will also utilize a reminder app to help maximize retention of study subjects and limit 
dropouts. The app, located on the study smartphone, called Where’s My Patch (WMP) will help 
encourage subject adherence to study medication administration by reminding them to place 
patches at their prespecified time each day. It also provides a body map to record daily patch 
locations as a visual reminder of where patches have already been placed over the past 14 days 
and to facilitate patch site rotation. Patch location data will only be retained locally on the 
smartphone and then automatically deleted after 14 days. Subject use of the MWP app will be 
encouraged, but not required. 
The study will begin with a Screening Period of at least 7 days (maximum of 28 days) prior to 
Visit 2/Baseline to ensure homogeneous baseline conditions can be established for all subjects. 
Subjects with prior intake of any dopamine agonists or taking L-dopa must discontinue the 
therapy at least 7 days prior to Visit 2/Baseline. Discontinuation of therapy must be driven by the 
subject’s medical need and not undertaken for the purpose of making a potential subject eligible 
for the study. 
The Screening Period will be followed by the Titration Period. Subjects will receive their first 
dose of study medication at Visit 3/Day 1. Subjects will be initiated either on placebo or 
1mg/24h rotigotine. The dose of rotigotine taken by subjects randomized to rotigotine will then 
be up-titrated on a weekly basis by 1mg/24h at a time to 2mg/24h or 3mg/24h, depending on the 
subject’s assigned dose level. 
Subjects will be administered study medication according to the dose titration schedule in 
Section 7.2.1. 
Subjects will be allowed to back-titrate 1 dose level during the Titration Period. Subjects are to 
complete the Titration Period at the back-titrated dose level and remain at this dose level for the 
duration of the Maintenance Period. If AEs occur during the Titration Period that are thought to

be the result of excessive dopaminergic stimulation (eg, intolerable nausea/vomiting), subjects 
should be back-titrated to their previous dose level and commence the Maintenance Period 
immediately. Subjects who do not tolerate the assigned dose in the first week (placebo or 
1mg/24h) will be withdrawn from the study. If subjects withdraw due to lack of efficacy, they 
are eligible to roll over to the open-label study, RL0007, after the 3 weeks of the Titration Period 
are completed. 
The Titration Period will be followed by a 12-week Maintenance Period. Subjects will remain at 
the assigned (or back-titrated) dose level throughout the Maintenance Period. At the end of the 
Maintenance Period, subjects will enter a Taper Period lasting up to a maximum of 4 days 
(de-escalation of study medication), followed by a 30-day Safety Follow-Up Period. 
Visits will be scheduled every week during the Titration Period. During the Maintenance Period, 
visits will be scheduled every 4 weeks. There is a 4-day interval until the end of the Taper 
Period, followed by a 30-day interval (±5 days) until the Safety Follow-Up Visit. Details are 
provided in the schedule of study assessments in Section 5.2.  
Plasma concentration of unconjugated rotigotine will be summarized by dose levels and visit. 
Plasma samples will be collected at Visit 6 and Visit 9. 
An interim analysis for futility (for the primary outcome measures only), with the possibility of 
stopping the study early, stopping a dose arm, or continuing the study as planned, will be 
performed with approximately 33% of the planned number of evaluable subjects; recruitment 
will not be stopped for the interim analysis. The futility criteria are defined in Section 13.7.  
An overview of the study activities is given in Table 5‒1 and Figure 5‒1. 
5.1.1 
Study duration per subject 
The total study duration per subject will be up to 24 weeks, including a 4-week Screening Period, 
a 3-week Titration Period, a 12-week Maintenance Period, a Taper Period of 4 days (with 
de-escalation by 1 dose step every 2 days), and a 30-day Safety Follow-Up Period (for subjects 
not participating in the open-label, long-term follow-up study). 
The end of the study is defined as the last visit of the last subject in the study. 
5.1.2 
Planned number of subjects and sites 
A total of 138 subjects are planned to be randomized during the study. A remote clinical study 
model in the USA is planned to be utilized in the study. 
5.1.3 
Anticipated regions and country 
This study will be conducted in the USA.

Rationale for study design and selection of dose 
SP1006 is a Phase 3, remote, double-blind, randomized, placebo-controlled study of fixed dose 
administration of the rotigotine transdermal system, designed to investigate the efficacy, safety, 
and tolerability of rotigotine in adolescent subjects 13 to 17 years of age. The study design is 
based on the FDA’s request to conduct a study in adolescents with RLS. The fixed dose levels of 
2mg/24h and 3mg/24h were chosen based on the results of the SP1004 PK/PD study in a similar 
population.  
The PK results of SP1004 were similar compared with those obtained in adults. Rotigotine 
plasma clearance was similar as compared to adults, although the mean value appeared to be 
somewhat higher; however, given the high variability, the meaning of this is negligible. Mean 
volume of distribution, AUC, and Cmax were similar to results obtained in adults earlier. 
In terms of safety, the rotigotine transdermal system was well tolerated at doses of up to 
3mg/24h in adolescent subjects with idiopathic RLS. No safety issues were identified in SP1004. 
A similar number of subjects reported treatment-emergent adverse events (TEAEs) in the 
0.5mg/24h, 1mg/24h, and 2mg/24h dose steps during the study, with fewer subjects reporting 
TEAEs in the 3mg/24h dose step. Overall, 62.5% reported TEAEs, and 45.8% reported 
drug-related TEAEs. The most frequently reported TEAEs (and drug-related TEAEs) were in the 
system organ class (SOC) of Gastrointestinal disorders, with nausea the most frequently reported 
TEAE by preferred term (PT). All of the TEAEs in this study were mild or moderate in intensity. 
No deaths, serious adverse events (SAEs), or TEAEs leading to discontinuation were reported 
during the study.  
Fourteen subjects from SP1004 were rolled over to open-label extension study SP1005 and were 
treated for up to 2 years. Overall, rotigotine was well tolerated with long-term use. 
Augmentation, defined as an increase in the severity of symptoms beyond baseline levels, 
represents the main complication of long-term dopaminergic treatment. Augmentation did not 
occur in SP1004; however, the study was too short to trigger augmentation with less than 
5 weeks of treatment in total. 
The 2mg/24h and 3mg/24h rotigotine doses chosen for testing in this protocol, SP1006, were 
selected by balancing the potential need for higher doses with the risk of augmentation as seen in 
adults receiving doses higher than 3mg/24h. Previous studies have indicated that the incidence of 
augmentation with rotigotine is low during 6 months and 1 year of treatment. Following an 
open-label extension study of the long-term safety and efficacy of rotigotine transdermal patch in 
adult patients with moderate-to-severe idiopathic RLS, a retrospective systematic analysis was 
conducted in order to investigate the 5-year incidence of augmentation. In this study, the dose 
was titrated in weekly increments (up to 4 weeks) from 0.5mg/24h to a maximum of 4mg/24h, 
followed by up to 5 years of maintenance at the optimum dose. Clinically significant 
augmentation was recorded in 8% of adult patients receiving rotigotine at doses of 4mg/24h 
compared with 5% of patients receiving rotigotine doses of ≤3mg/24h (Oertel et al, 2011).

1. An Institutional Review Board (IRB)/Independent Ethics Committee (IEC) approved written 
Informed Consent form is signed and dated by the subject or by the parent(s) or legal 
representative. The Informed Consent form or a specific Assent form, where required, will be 
signed and dated by minors. 
2. Subject/legal representative is considered reliable and capable of adhering to the protocol 
(eg, able to understand and complete questionnaires), visit schedule, and medication intake 
according to the judgment of the investigator. 
3. Subject is male or female, and is ≥13 and <18 years of age at Baseline. 
4. Subject weighs ≥40kg. 
5. Deleted. 
6. Subject meets the diagnosis of RLS based on all of the following features according to the 
2013 Revised International RLS Group Diagnostic Criteria (Pichietti et al, 2013): 
− An urge to move the legs usually, but not always, accompanied by or felt to be caused by 
uncomfortable and unpleasant sensations in the legs (sometimes the urge to move the legs 
is present without the uncomfortable sensations and sometimes the arms or other parts of 
the body are involved in addition to the legs. For children, the description of these 
symptoms should be in the child’s own words.). 
− The urge to move the legs and any accompanying unpleasant sensations begin or worsen 
during periods of rest or inactivity such as lying down or sitting. 
− The urge to move the legs and any accompanying unpleasant sensations are partially or 
totally relieved by movement, such as walking or stretching, at least as long as the 
activity continues (when symptoms are very severe, relief by activity may not be 
noticeable but must have been previously present). 
− The urge to move the legs and any accompanying unpleasant sensations during rest or 
inactivity only occur or are worse in the evening or night than during the day (when 
symptoms are very severe, the worsening at night may not be noticeable but must have 
been previously present). 
− The occurrence of the above features is not solely accounted for as symptoms primary to 
another medical or behavioral condition (eg, myalgia, venous stasis, leg edema, arthritis, 
leg cramps, positional discomfort, habitual foot tapping). 
7. Subject’s RLS symptoms cause significant daytime symptoms or significant distress or 
impairment in social, occupational, educational, or other important areas of functioning by 
the impact on sleep, energy/vitality, daily activities, behavior, cognition or mood. 
8. At Baseline, subject has a score of ≥15 on the IRLS Rating Scale (indicating 
moderate-to-severe RLS). 
9. At Baseline, subject scores ≥4 points on the CGI Item 1 assessment (indicating at least 
moderately ill).

reason(s) for removing the subject, must be recorded in the source documents. The eCRF must 
document the primary reason for withdrawal or discontinuation. 
Investigators should contact the Medical Monitor, whenever possible, to discuss the withdrawal 
of a subject in advance. 
6.3.1 
Potential drug-induced liver injury IMP discontinuation criteria 
Subjects with potential drug-induced liver injury (PDILI) must be assessed to determine if IMP 
must be discontinued. In addition, all concomitant medications and herbal supplements that are 
not medically necessary should also be discontinued.  
The PDILI criteria below require immediate and permanent discontinuation of IMP:  
• Subjects with either of the following: 
− ALT or AST ≥ 5xULN 
− ALT or AST ≥3xULN and coexisting total bilirubin ≥2xULN  
The PDILI criterion below requires immediate discontinuation of IMP: 
• Subjects with ALT or AST ≥3xULN who exhibit temporally associated symptoms of 
hepatitis or hypersensitivity. Hepatitis symptoms include fatigue, nausea, vomiting, right 
upper quadrant pain or tenderness. Hypersensitivity symptoms include fever (without clear 
alternative cause), rash, or eosinophilia (ie, >5%). 
If a nondrug-related cause for the symptoms can be confirmed, these subjects may resume IMP 
administration after discussion with the responsible UCB physician, but only when the 
requirements for rechallenge with IMP as provided in Section 11.6.1.2 are followed. 
The PDILI criterion below allows for subjects to continue on IMP at the discretion of the 
investigator.  
• Subjects with ALT or AST ≥3xULN (and ≥2x baseline) and <5xULN, total bilirubin 
<2xULN, and no eosinophilia (ie, ≤5%), with no fever, rash, or symptoms of hepatitis (eg, 
fatigue, nausea, vomiting, right upper quadrant pain or tenderness). 
Evaluation of PDILI must be initiated as described in Section 11.6.1. If subjects are unable to 
comply with the applicable monitoring schedule, IMP must be discontinued immediately. 
Investigators should attempt to obtain information on subjects in the case of IMP discontinuation 
to complete the final evaluation. Subjects with PDILI should not be withdrawn from the study 
until investigation and monitoring are complete. All results of these evaluations and 
observations, as well as the reason(s) for IMP discontinuation and subject withdrawal (if 
applicable), must be recorded in the source documents. The eCRF must document the primary 
reason for IMP discontinuation.

• The patch should be worn continuously for 24 hours. After 24 hours, the patch should be 
removed and a new one applied immediately. The WMP app on the study smartphone 
provides a reminder to place patches at a subject’s prespecified time each day (see Section 5 
for an overview). 
• The patch should be applied to an area of clean, dry, and healthy skin on the stomach, thigh, 
hip, flank (side of the body between the ribs and the pelvis), shoulder, or upper arm. 
• Each patch should be applied to a different place on the skin each day, for example, from the 
right side to the left side and from the upper body to the lower body. The patch should not be 
applied to the same application site more than once every 14 days. The WMP app on the 
study smartphone provides a body map to record daily patch location and a visual reminder 
of where patches have been placed over the past 14 days (see Section 5 for an overview). 
• When applied, the patch should be pressed firmly into place with the palm of the hand for 
30 seconds to make sure there is good contact with the skin, especially around the edges. 
• If it is necessary to apply the patch to a hairy area, the area should be clipped at least 3 days 
prior to applying the patch. 
• The patch should not be applied to areas where it could be rubbed by tight clothing or under a 
waistband. 
• Avoid applying the patch on skin folds or body areas of increased sweating. 
• Do not apply the patch to skin that is red, irritated, or injured. 
• Creams, lotions, ointments, oils, and powders should not be applied to the skin area where 
the patch will be placed. 
• Subjects and legal representatives (ie, parents/guardians) should wash their hands with soap 
and water immediately after handling the patch. 
7.2.3 
Removal instructions 
Following are instructions for patch removal: 
• Slowly and carefully peel off the used patch which still contains some of the drug. 
• Carefully fold it in half (sticky sides together) and throw it in the trash. 
• Gently wash the area with warm water and mild soap to remove any adhesive that stays on 
the skin. Baby oil may also be used to remove any excess residue. Alcohol or other solvents, 
such as nail polish remover, may cause skin irritation and should not be used. 
• Subjects may see mild redness at the site when a patch is removed. This redness should 
disappear over time. If uncomfortable irritation or excessive itchiness continues, subjects 
and/or their parent/guardian should tell their investigator. 
7.2.4 
General instructions 
Following are general instructions: 
• Contact with water while bathing, showering, swimming will not change the way that 
rotigotine works; however, these activities could loosen the patch. If a patch falls off,

re-apply a new patch for the remainder of the day. A new patch should be applied the next 
day on the subject’s regular schedule. The location of a replacement patch can be recorded in 
the WMP app on the study smartphone (see Section 5 for an overview). 
• If the subject forgets to apply a patch at the usual time, the subject should remove the patch 
he/she is currently wearing and put a new patch on a different area of skin. Then apply a new 
patch the next day on the subject’s regular schedule. 
• Avoid applying heating pads or other sources of external heat to the patch. Avoid exposing 
the patch to direct sunlight. 
• If the subject develops a skin rash or irritation from the patch, avoid direct sunlight on the 
area until the skin heals because this exposure could lead to changes of skin color. 
• Subjects should not reduce the dosage or stop applying a patch without first talking with their 
investigator. 
• Do not cut or damage the patch. 
• After 24 hours, the patches should be removed and new ones applied right away to a different 
area of skin. 
• To avoid potential burns, the patch should be removed before undergoing cardioversion or a 
diagnostic procedure known as magnetic resonance imaging. 
• The patches should be stored according to the labeling on the clinical trial supply packaging. 
Do not store the patch outside pouch. 
7.3 
Packaging 
The IMP will be packaged and labeled by UCB according to current Good Manufacturing 
Practice (GMP) guidelines and the applicable laws and guidelines. The sponsor will provide site 
boxes containing complete study medication. The site boxes will be packaged in such a way as to 
protect the product from deterioration during transport and storage. 
7.4 
Labeling 
Clinical drug supplies will be labeled in accordance with the current International Council for 
Harmonisation (ICH) guidelines on Good Clinical Practice (GCP) and GMP and will include any 
locally required statements. If necessary, labels will be translated into the local language. 
7.5 
Handling and storage requirements 
Rotigotine transdermal patches should be stored in the original pouch. Rotigotine should be 
stored according to the labeling on the clinical trial supply packaging. The investigator (or 
designee) is responsible for the safe and proper storage of rotigotine at the site. Rotigotine stored 
by the investigator (or designee) is to be kept in a secured area with limited access according to 
the storage conditions mentioned on the label. 
Appropriate storage conditions must be ensured either by controlled room temperature or by 
completion of a temperature log in accordance with local requirements on a regular basis 
(eg, once a week), showing minimum and maximum temperatures reached over the time interval.

In case an out-of-range temperature is noted, it must be immediately communicated to the 
Sponsor’s designee in accordance with the Pharmacy Manual. The investigator (or designee) will 
instruct the subject to store the IMP following the instructions on the label. Detailed information 
on handling the IMP will be given in the Pharmacy Manual. 
As part of the remote study model, the study site’s depot/pharmacy will provide study 
medication and all required supplies via direct-to-subject shipments. Once eligibility is 
confirmed, the study site will contact the interactive response technology (IRT) for 
randomization assignment, and shipments will be prepared and sent out for delivery to the 
subject’s/legal representative’s home/preferred address. Shipments will be confirmed as 
delivered by the study staff, with appropriate documentation in the subject’s study records. The 
study medication will be confirmed as received in good condition and within the acceptable 
temperature range (ie, fit for use). A telemedicine call will be completed to instruct the 
subject/legal representative on the correct storage and administration of the study medication, 
which will also be documented as part of subject’s study record. 
7.6 
Drug accountability 
At the designated timepoints during the study, subjects/legal representatives will return to the 
study site’s depot/pharmacy the unused study medication patches remaining as part of the 
medication kits, along with the kit itself, via the return shipment materials provided. A Drug 
Accountability form will be used to record IMP dispensing and return information on a 
by-subject basis and will serve as source documentation during the course of the study. Details of 
any IMP lost, damaged (due to breakage or wastage), not used, disposed of at the study site’s 
depot/pharmacy, or returned to the sponsor or designee must also be recorded on the appropriate 
forms. All supplies and drug accountability documentation must be made available throughout 
the study for UCB (or designee) to review. 
The investigator (or designee) is responsible for retaining all used, unused, and partially used 
containers of IMP until returned or destroyed. 
The investigator may assign some of the investigator’s duties for drug accountability at the study 
site’s depot/pharmacy to an appropriate designee. 
The investigator must ensure that the IMP is used only in accordance with the protocol. 
Periodically, and/or after completion of the clinical phase of the study, all used (including empty 
containers) and unused IMP containers must be reconciled and returned to UCB (or designee), 
preferably in their original package. Investigational medicinal product intended for the study 
cannot be used for any other purpose than that described in this protocol. 
7.7 
Procedures for monitoring subject compliance 
At the designated visits (see Table 5‒1), subjects/legal representatives will return all unused IMP 
and empty IMP containers, using the return shipment supplies provided to them by the study 
staff. Upon receipt of the returned medication at the study site’s depot/pharmacy, the designated 
study staff will review drug accountability with the subject/legal representative via a telephone 
or a telemedicine call in order to obtain explanations regarding any discrepancies in compliance 
with the dosing regimen.

Procedures for maintaining and breaking the treatment blind 
7.9.1.1 
Maintenance of study treatment blind 
All subject treatment details (ie, subject-related information about assigned kit numbers as listed 
in the randomization schedule) will be allocated and maintained by the IRT. 
UCB personnel, as well as contract research organization (CRO) personnel involved in the study 
for clinical monitoring, will be blinded to the treatment assignment with the following 
exceptions: 
• Sponsor Clinical Study Supplies Coordinator and personnel directly involved in 
manufacturing/packaging of the IMP 
• Bioanalytical personnel involved in the bioanalytical analysis of the PK samples 
• Sponsor pharmacovigilance personnel reporting SAEs to regulatory authorities 
• IRT services personnel 
7.9.1.2 
Breaking the treatment blind in an emergency situation 
In the event of an emergency, it will be possible to determine to which treatment arm and dose 
the subject has been allocated by contacting the IRT. The study site will be provided with details 
of how to contact the system for code breaking at the start of the study. The Medical Monitor or 
equivalent should be consulted prior to unblinding, whenever possible. 
The clinical project manager (CPM) will be informed immediately via the IRT when a code is 
broken, but will remain blinded to specific treatment information. Any unblinding of the IMP 
performed by the investigator must be recorded in the source documents and on the Study 
Termination eCRF page. 
An emergency envelope (or equivalent) containing the randomization code will be printed for 
each subject in a double-blind study and must not be broken, except for emergency situations.  
7.10 
Randomization and numbering of subjects 
An IRT will be used for assigning eligible subjects to a treatment regimen based on a 
predetermined production randomization and/or packaging schedule provided by UCB (or 
designee). The IRT will generate individual assignments for subject kits of study drug, as 
appropriate, according to the visit schedule. 
To enroll a subject (Visit 1), the investigator or designee will contact the IRT and provide brief 
details about the subject to be enrolled. Each subject will receive a 5-digit number assigned at 
screening that serves as the subject identifier throughout the study. The subject number will be 
required in all communication between the investigator or designee and the IRT regarding a 
particular subject. Subject numbers and kit numbers will be tracked via the IRT.  
To randomize a subject (Visit 2/Baseline), the investigator or designee will contact the IRT and 
provide brief details about the subject to be randomized. The IRT will automatically inform the

STUDY PROCEDURES BY VISIT  
8.1 
Screening Period 
Prior to any study activities, subjects will be asked to read and sign an Informed Consent form 
and/or Assent form that has been approved by an IRB/IEC and which complies with regulatory 
requirements. See Section 14.1 for a description of the informed consent process for the remote 
study model. 
Subjects will be given adequate time to consider any information concerning the study, given to 
them by the investigator or designee. As part of the Informed Consent procedure, subjects will be 
given the opportunity to ask the investigator any questions regarding potential risks and benefits 
of participation in the study. 
Once consented, study supplies, including screening lab kits and study instructions, will be 
shipped out to the subject/legal representative. The initial shipment of study supplies will include 
the study-issued smartphone which subjects/legal representatives will utilize throughout the 
study to communicate with the study team and to complete various study procedures, such as 
questionnaires. The telemedicine functionality of PLATFORM (see Section 2 for an overview) 
may also be used for the designated study visits. Subject/legal representative will return the 
smartphone to the study site once study participation is completed. Additional supplies will be 
sent to the subject/legal representative as needed throughout the study. 
Subjects who have been screened but not randomized may be rescreened with the permission of 
the Study Physician or representative.

International Restless Legs Rating Scale (IRLS) 
The IRLS will be performed at Screening, Baseline (Visit 2), Visit 6, Visit 7, Visit 8, and Visit 9. 
The IRLS should also be performed in the event that a subject is prematurely withdrawn from the 
study (Withdrawal Visit). 
The IRLS was developed by the International RLS Study Group and was validated in a 
large-scale study (Walters et al, 2003). The IRLS is intended to evaluate, in a standardized way, 
the subjective intensity of major symptoms of RLS and, in 2 items (9 and 10), the impact of the 
disease on subjects’ functioning in daytime activities by use of a 5-point scale for each of a total 
of 10 items: 
1. Discomfort in arms and legs due to RLS 
2. Urge to move 
3. Relief of symptoms by movement 
4. Sleep disturbances due to RLS 
5. Fatigue and somnolence during the day due to RLS  
6. Global severity rating of RLS 
7. Frequency of symptoms 
8. Severity of symptoms (if present) during an average day (24 hours) 
9. Impact of symptoms on daytime activities (family, home, social, job) 
10. Impact of symptoms on mood (eg, angry, depressed, sad, anxious, irritable) 
Each item is scored by the subject. Investigators or clinic personnel can assist the subject if 
he/she has difficulty understanding the items or locating the appropriate score. Scores for each 
item range from 0 (not present) to 4 (very severe). A sum score of all 10 items is calculated for 
analysis. The sum score ranges from 0 (no RLS symptoms present) to 40 (maximum severity in 
all symptoms).  
The following ranges are used to determine severity categories: 
• 0=none 
• 1 to 10=mild 
• 11 to 20=moderate 
• 21 to 30=severe 
• 31 to 40=very severe 
A minimum score of 15 points (moderate) is typically required for inclusion in a study at 
Baseline.  
Subjects should answer each item in reference to the 7 days prior to their visit. If the timeframe 
since the last visit is <7 days (eg, in the event of premature discontinuation), the subject should 
answer each item in reference to the days since their last visit. 
Subjects will be classified into the following categories:

• IRLS responder: A relative reduction in IRLS total score in percentage points at the end of 
maintenance compared to Baseline. This categorization will be carried out for a reduction of 
at least 50% (that is a percentage relative change for less than or equal to -50%), 
• IRLS remitter: Two types of IRLS remitter are defined: 1) an IRLS total score of 10 or less 
(remitter criterion 1) and 2) an IRLS total score of 0 (remitter criterion 2). 
9.2 
Clinical Global Impressions 
The CGI Item 1 will be performed at Screening, Baseline (Visit 2), and Visit 6 through Visit 9 
(Guy and Bonato, 1970). 
Item 1 (Severity of Illness): Scores range 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 is to be completed during an interview between the subject and the investigator 
or designee. 
Note that at Baseline a minimum CGI Item 1 score of 4 points (indicating at least moderately ill) 
is typically required for inclusion in RLS studies. 
Subjects will be classified into the following category: 
• CGI Item 1 responder: A relative reduction in CGI Item 1 (severity of illness) in percentage 
points of at least 50% at the respective visit compared to Baseline (ie, a percentage relative 
change for less than or equal to –50%) 
CGI is validated in mental diseases only; but it is widely used. 
9.3 
RLS-6 
The RLS-6 will be performed at Baseline (Visit 2) and at Visit 6 through Visit 9. The RLS-6 
should also be performed in the event that a subject is prematurely withdrawn from the study 
(Withdrawal Visit). 
The RLS-6 Rating Scales is designed to assess the severity of RLS (Kohnen et al, 2003) and 
consists of 6 subscales. The subscales assess 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 assess satisfaction with sleep and 
severity of daytime tiredness/sleepiness. 
Scores for each of the 6 subscales range from 0 (completely satisfied) to 10 (completely 
dissatisfied). 
Each subscale item should be scored by the subject. Investigators or clinic personnel can assist 
the subject if he/she has difficulty understanding the subscale. Subjects should answer each 
subscale in reference to the 7 days prior to their visit. If the timeframe since the last visit is <7 
days (eg, in the event of premature discontinuation), the subject should answer each subscale in 
reference to the days since their last visit. 
The change from baseline will be derived for each of the 6 subscales. 
No sum score will be calculated.

Subject Quality of Life Questionnaire 
The RLS-QoL will be performed at Visit 2, Visit 6, and Visit 9. The RLS-QoL should also be 
performed in the event that a subject is prematurely withdrawn from the study (Withdrawal 
Visit). 
The RLS-QoL (Kohnen et al, 2002) will be used to evaluate quality of life at these visits. This 
disease-specific instrument consists of 12 items. The most relevant item is a global rating of 
quality of life “all in all”. 
Further items are related to consequences of the RLS symptoms on sleep, activities of daily 
living, mood, and social interactions, to the consequences of disturbed sleep on everyday life and 
to those of tiredness during the day on mood; furthermore, consequences of pain and side effects 
of treatments on daily activities are to be evaluated. A final section of the questionnaire asks for 
evaluation of coping behavior (effort of measures to get relief from the symptoms, avoidance of 
social situations, changes in life style). The main outcome parameter is a total score which is 
calculated from all items.

ASSESSMENT OF PHARMACOKINETIC VARIABLES 
10.1 
Blood sampling for the determination of rotigotine plasma 
concentrations 
For the determination of unconjugated rotigotine, 5.5mL of blood will be drawn prior to patch 
removal by venous puncture or indwelling venous catheter into lithium heparinized tubes at 
Visit 6 and Visit 9 (refer to Table 5‒1 for timing of PK assessments). The sampling time should 
be recorded on the eCRF when PK samples are to be taken. The application site and time of last 
application of the study medication prior to the PK assessment will also be collected. 
Treatment of the venous puncture or indwelling venous catheter site with a topical anesthetic 
(eg, EMLA) prior to the needle stick is permissible. 
Details can be found in the study lab manual. 
10.2 
Shipment procedures 
Details can be found in the study lab manual. 
10.3 
Bioanalytical method 
Plasma concentrations of requested analytes will be determined with validated bioanalytical 
methods. After the sample preparation step, the target compounds are separated by a reversed-
phase liquid chromatography and detected by electrospray ionization tandem mass spectrometry 
using multiple reaction monitoring in positive-ion mode. 
11 
ASSESSMENT OF SAFETY 
Refer to Table 5‒1 for timings of all safety assessments. In addition to the AE assessments 
completed at the designated study visits (see Table 5‒1 and Section 8), the subjects/legal 
representatives are also able to contact study staff at any time via the study-issued smartphone to 
discuss their condition, ask questions, and/or report AEs/SAEs. All AEs and SAEs will be 
evaluated and reported as noted below. Based on the investigator’s evaluation of the AE/SAE,

appropriate medical intervention/support measures will be instituted as necessary (ie, urgent care 
services, etc) and documented as part of the subject’s study record. 
11.1 
Adverse events 
11.1.1 
Definitions 
11.1.1.1 
Adverse event  
An AE is any untoward medical occurrence in a patient or clinical investigation subject 
administered a pharmaceutical product that does not necessarily have a causal relationship with 
this treatment. An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease temporally associated with the use of a 
medicinal (investigational) product, whether or not related to the medicinal (investigational) 
product. 
In order to ensure complete safety data collection, all AEs occurring during the study (ie, after 
the signing of the Informed Consent form), including any pretreatment and posttreatment periods 
required by the protocol, must be reported in the eCRF even if no IMP was taken but specific 
study procedures were conducted. This includes all AEs not present prior to the initial visit and 
all AEs that recurred or worsened after the initial visit. 
Signs or symptoms of the condition/disease for which the IMP is being studied should be 
recorded as AEs only if their nature changes considerably or their frequency or intensity 
increases in a clinically significant manner as compared to the clinical profile known to the 
investigator from the subject’s history or the Baseline Period.  
11.1.1.2 
Serious adverse event 
Once it is determined that a subject experienced an AE, the seriousness of the AE must be 
determined. An SAE must meet 1 or more of the following criteria: 
• Death 
• Life-threatening 
(Life-threatening does not include a reaction that might have caused death had it occurred in 
a more severe form.) 
• Significant or persistent disability/incapacity 
• Congenital anomaly/birth defect (including that occurring in a fetus) 
• Important medical event that, based upon appropriate medical judgment, may jeopardize the 
patient or subject and may require medical or surgical intervention to prevent 1 of the other 
outcomes listed in the definition of serious 
(Important medical events may include, but are not limited to, potential Hy’s Law [see 
Section 11.1.1.3], allergic bronchospasm requiring intensive treatment in an emergency room 
or at home, blood dyscrasias that do not result in inpatient hospitalization, or the 
development of drug dependency or drug abuse.) 
• Initial inpatient hospitalization or prolongation of hospitalization

(A patient admitted to a hospital, even if he/she is released on the same day, meets the 
criterion for the initial inpatient hospitalization. An emergency room visit that results in 
admission to the hospital would also qualify for the initial inpatient hospitalization criteria. 
However, emergency room visits that do not result in admission to the hospital would not 
qualify for this criteria and, instead, should be evaluated for 1 of the other criteria in the 
definition of serious [eg, life-threatening adverse experience, ecg]. 
Hospitalizations for reasons not associated with the occurrence of an AE [eg, preplanned 
surgery or elective surgery for a pre-existing condition that has not worsened or manifested 
in an unusual or uncharacteristic manner] do not qualify for reporting. For example, if a 
subject has a condition recorded on his/her medical history and later has a preplanned surgery 
for this condition, it is not appropriate to record the surgery or hospitalization as an SAE, 
since there is no AE upon which to assess the serious criteria. Please note that, if the 
pre-existing condition has worsened or manifested in an unusual or uncharacteristic manner, 
this would then qualify as an AE and, if necessary, the seriousness of the event would need to 
be determined.) 
11.1.1.2.1 
Anticipated serious adverse events 
The following Anticipated SAEs are anticipated to occur in the population studied in this 
protocol at some frequency that is independent of drug exposure.  
This list does not change the investigator’s obligation to report all SAEs (including Anticipated 
SAEs) as detailed in Section 11.1.2.3.

11.1.1.3 
Adverse events of special interest 
An AE of special interest is any AE that a regulatory authority has mandated be reported on an 
expedited basis, regardless of the seriousness, expectedness, or relatedness of the AE to the 
administration of a UCB product/compound. 
Potential Hy’s Law, defined as ≥3xULN ALT or AST with coexisting ≥2xULN total bilirubin in 
the absence of ≥2xULN ALP, with no alternative explanation for the biochemical abnormality, 
must ALWAYS be reported to UCB as an AE of special interest (ie, without waiting for any 
additional etiologic investigations to have been concluded). Follow-up information should then 
be reported if an alternative etiology is identified during investigation and monitoring of the 
subject.

11.1.2 
Procedures for reporting and recording adverse events 
The subject will be given the opportunity to report AEs spontaneously. A general prompt will 
also be given at each study visit to detect AEs. For example: 
“Did you notice anything unusual about your health (since your last visit)?” 
In addition, the investigator should review any self-assessment procedures (eg, diary cards) 
employed in the study. 
11.1.2.1 
Description of adverse events 
When recording an AE, the investigator should use the overall diagnosis or syndrome using 
standard medical terminology, rather than recording individual symptoms or signs. The eCRF 
and source documents should be consistent. Any discrepancies between the subject’s own words 
on his/her own records (eg, diary card) and the corresponding medical terminology should be 
clarified in the source documentation. 
Details for completion of the Adverse Event eCRF (including judgment of relationship to IMP) 
are described in the eCRF Completion Guidelines. 
11.1.2.2 
Rule for repetition of an adverse event 
An increase in the intensity of an AE should lead to the repetition of the AE being reported with: 
• The outcome date of the first AE that is not related to the natural course of the disease being 
the same as the start date of the repeated AE, and the outcome of “worsening” 
• The AE verbatim term being the same for the first and repeated AE, so that the repeated AE 
can be easily identified as the worsening of the first one 
11.1.2.3 
Additional procedures for reporting serious adverse events 
If an SAE is reported, UCB must be informed within 24 hours of receipt of this information by 
the site (see contact information for SAE reporting listed in the Serious Adverse Event Reporting 
section at the front of the protocol). The investigator must forward to UCB (or its representative) 
a duly completed “Investigator SAE Report Form for Development Drug” (SAE Report form) 
provided by UCB, even if the data are incomplete, or if it is obvious that more data will be 
needed in order to draw any conclusions. Information recorded on this form will be entered into 
the global safety database. 
An Investigator SAE Report form will be provided to the investigator. The Investigator SAE 
Report form must be completed in English.  
It is important for the investigator, when completing the SAE Report form, to include the 
assessment as to a causal relationship between the SAE and the IMP administration. This insight 
from the investigator is very important for UCB to consider in assessing the safety of the IMP 
and in determining whether the SAE requires reporting to the regulatory authorities in an 
expedited manner. 
Additional information (eg, autopsy or laboratory reports) received by the investigator must be 
provided within 24 hours. All documents in the local language must be accompanied by a 
translation in English, or the relevant information included in the same document must be 
summarized in the Investigator SAE Report form.

The investigator is specifically requested to collect and report to UCB (or its representative) any 
SAEs (even if the investigator is certain that they are in no way associated with the IMP), up to 
30 days from the end of the study for each subject, and to also inform participating subjects of 
the need to inform the investigator of any SAE within this period. Serious AEs that the 
investigator thinks may be associated with the IMP must be reported to UCB regardless of the 
time between the event and the end of the study. 
Upon receipt of the SAE Report form, UCB will perform an assessment of expectedness of the 
reported SAE. The assessment of the expectedness of the SAE is based on the Investigator’s 
Brochure. 
11.1.3 
Follow up of adverse events 
An AE should be followed until it has resolved, has a stable sequelae, the investigator determines 
that it is no longer clinically significant, or the subject is lost to follow up. This follow-up 
requirement applies to AEs, SAEs, and AEs of special interest; further details regarding follow 
up of PDILI events is provided in Section 11.6.1.4.  
If an AE is ongoing at the end of the study for a subject, follow up should be provided until 
resolution/stable level of sequelae is achieved, or until the investigator no longer deems that it is 
clinically significant, or until the subject is lost to follow up. If no follow up is provided, the 
investigator must provide a justification. The follow up will usually be continued for 30 days 
days after the subject has discontinued his/her IMP. 
Information on SAEs obtained after clinical database lock will be captured through the Patient 
Safety (PS) database without limitation of time. 
11.2 
Pregnancy 
If an investigator is notified that a subject has become pregnant after the first intake of any IMP, 
the investigator must immediately notify UCB’s PS department by providing the completed 
Pregnancy Report and Outcome form (for contact details see Serious Adverse Event reporting 
information at the beginning of this protocol). The subject should be withdrawn from the study 
as soon as pregnancy is known (by positive pregnancy test), and the following should be 
completed: 
• An early discontinuation visit should be conducted. 
• The subject should immediately stop the intake of the IMP or be down-titrated as instructed 
at the early discontinuation visit.  
• A Safety Follow-Up Visit should be scheduled 30 days ±5 days after the subject has 
discontinued her IMP. 
The investigator must inform the subject of information currently known about potential risks 
and about available treatment alternatives. 
The pregnancy will be documented on the Pregnancy Report and Outcome form provided to the 
investigator. The progression of the pregnancy and the eventual birth (if applicable) must be 
followed up using the Pregnancy Report and Outcome form in which the investigator has to 
report on the health of the mother and of the child. Every reasonable attempt should be made to 
follow the health of the child for 30 days after birth for any significant medical issues. In certain

circumstances, UCB may request that follow up is continued for a period longer than 30 days. If 
the subject is lost to follow up and/or refuses to give information, written documentation of 
attempts to contact the subject needs to be provided by the investigator and filed at the site. 
UCB’s PS department is the primary contact for any questions related to the data collection for 
the pregnancy, eventual birth, and follow up. 
In cases where the partner of a male subject enrolled in a clinical study becomes pregnant, the 
investigator or designee is asked to contact the subject to request consent of the partner via the 
Partner Pregnancy Consent form that has been approved by the responsible IRB/IEC and should 
be available in the investigator site file (ISF). In case of questions about the consent process, the 
investigator may contact the UCB/CRO contract monitor for the study. The investigator will 
complete the Pregnancy Report and Outcome form and send it to UCB’s PS department (for 
contact details see Serious Adverse Event reporting information at the beginning of this protocol) 
only after the partner has agreed that additional information can be captured and has provided the 
signed Partner Pregnancy Consent form. UCB’s PS department is also the primary contact for 
any questions related to the data collection for the partner pregnancy, eventual birth, and follow 
up. 
A pregnancy becomes an SAE in the following circumstances: miscarriage, abortion (elective or 
spontaneous), unintended pregnancy after hormonal contraceptive failure (if the hormonal 
contraceptive was correctly used), ectopic pregnancy, fetal demise, or any congenital 
anomaly/birth defect of the baby. Those SAEs must be additionally reported using the 
Investigator SAE Report form. 
11.3 
Suspected transmission of an infectious agent 
With respect to the rotigotine transdermal patch, it is not likely that transmission of an infectious 
agent will occur in clinical practice. For the purposes of reporting, any suspected transmission of 
an infectious agent via a medicinal product should be considered as an SAE; such cases must be 
reported immediately, recorded in the AE module of the eCRF, and followed as any other SAE. 
Any organism, virus, or infectious particle (eg, prion protein transmitting transmissible 
spongiform encephalopathy), pathogenic or nonpathogenic, is considered an infectious agent. 
11.4 
Overdose of investigational medicinal product 
With respect to the rotigotine transdermal patch, it is not likely that significant overdosing will 
occur in clinical practice unless subjects forget to remove the previous day’s patch; subjects 
should be warned against this possibility. 
Excessive dosing (beyond that prescribed in the protocol and including overdose) should be 
recorded in the eCRF. Any SAE or nonserious AE associated with excessive dosing must be 
followed as any other SAE or nonserious AE. These events are only considered AEs or SAEs if 
there are associated clinical signs and symptoms or if the act of taking the excess medicine itself 
is an AE or SAE (eg, suicide attempt). 
11.5 
Safety signal detection 
Selected data from this study will be reviewed periodically to detect as early as possible any 
safety concern(s) related to the IMP so that investigators, clinical study subjects, regulatory 
authorities, and IRBs/IECs will be informed appropriately and as early as possible.

The Study Physician or medically qualified designee/equivalent will conduct an ongoing review 
of SAEs and perform ongoing SAE reconciliations in collaboration with the PS representative. 
As appropriate for the stage of development and accumulated experience with the IMP, 
medically qualified personnel at UCB may identify additional safety measures (eg, AEs, vital 
signs, laboratory or ECG results) for which data will be periodically reviewed during the course 
of the study. 
11.6 
Laboratory measurements 
A central laboratory will perform routine hematology, clinical chemistry, and hormone analyses. 
It is recommended that subjects be scheduled for morning appointments to complete these 
procedures. However, if morning appointments are not feasible, then subjects should continue to 
be scheduled at approximately the same time of day as all other visits. 
Treatment of the venous puncture or indwelling venous catheter site with a topical anesthetic (eg, 
EMLA) prior to the needle stick is permissible. 
Urinalyses are performed locally using urine dipsticks. If the dipstick results are abnormal and of 
clinical concern, a repeat sample will be sent to the central laboratory for evaluation. 
The laboratory parameters listed in Table 11‒2 will be measured.

11.6.1 
Evaluation of PDILI 
The PDILI IMP discontinuation criteria for this study are provided in Section 6.3.1, with the 
accompanying required follow-up investigation and monitoring detailed below. All PDILI events 
must be reported as an AE and reported to the study site and sponsor within 24 hours of learning 
of their occurrence. Any PDILI event that meets the criterion for potential Hy’s Law must be 
reported as an AE of special interest (see Section 11.1.1.3), and, if applicable, also reported as an 
SAE (see Section 11.1.1.2).  
Evaluation of PDILI consists of the diagnostic testing and continued monitoring included in 
Table 11‒3 (specific tests dependent on laboratory results and corresponding symptoms) and 
consultation with a local hepatologist (if applicable; discussed in Section 11.6.1.1). The local 
hepatologist is the expert usually consulted by the treating physician for assessment and 
management of potential hepatic disease. This would usually be a hepatologist, but may be a 
gastroenterologist. Additional investigation and monitoring may be required and adapted based 
on the diagnosis after the cause of the liver injury/abnormality is confirmed (details in 
Section 11.6.1.4). 
The results of all monitoring, including laboratory testing and other testing, should be made 
available to the study site and sponsor. 
All initial tests resulting in abnormal hepatic laboratory values need to be repeated, but 
appropriate medical action must not be delayed waiting for the repeat result. 
If tests are done locally for more rapid results, a concurrent sample should also be sent to the 
central laboratory whenever possible. Medical care decisions are to be made initially using the 
most rapidly available results and a conservative approach must be taken if the results from the 
2 laboratory tests are significantly different. Data from the local and central laboratory are to be 
recorded on the applicable eCRF pages. 
When IMP is discontinued, all concomitant medications and herbal supplements that are not 
medically necessary should also be discontinued. In these cases, the investigator should also 
consider dose reduction for medically necessary concomitant medication and consider changing 
any medically required concomitant medication known to be hepatotoxic to a suitable 
alternative. 
When IMP is stopped due to PDILI (as described in Section 6.3.1), IMP must be permanently 
discontinued unless a subsequent alternative diagnosis fully explains the hepatic findings.  
Rechallenge with a substance potentially causing drug-induced liver injury is dangerous, may be 
fatal, and must not occur. 
The table below summarizes the approach to investigate PDILI.

11.6.1.1 
Consultation with Medical Monitor and local hepatologist  
Potential drug-induced liver injury events require notification of the Medical Monitor within 
24 hours (eg, by laboratory alert), and the subject must be discussed with the Medical Monitor as 
soon as possible. If required, the subject must also be discussed with the local hepatologist. The 
local hepatologist is the expert usually consulted by the treating physician for assessment and 
management of potential hepatic disease. This would usually be a hepatologist, but may be a 
gastroenterologist. If determined necessary, this discussion should be followed by a full 
hepatology assessment (see Section 11.6.1.3) and SAE report (if applicable). 
11.6.1.2 
Immediate action: determination of IMP discontinuation 
All PDILI events require immediate action, testing, and monitoring.  
The immediate action is dependent on the laboratory values and symptoms of hepatitis or 
hypersensitivity and ranges from continuation of IMP (followed by immediate investigation) to 
immediate and permanent discontinuation (see Section 6.3.1 and Table 11‒3 for details). 
When IMP is discontinued, all concomitant medications and herbal supplements that are not 
medically necessary should also be discontinued. The investigator should also consider dose 
reduction for medically necessary concomitant medication and consider changing any medically 
required concomitant medication known to be hepatotoxic to a suitable alternative. 
11.6.1.3 
Testing: identification/exclusion of alternative etiology 
The measurements and additional information required for the assessment of PDILI events when 
there is a reasonable possibility that they may have been caused by the IMP are detailed in 
Table 11‒4 (laboratory measurements) and Table 11‒5 (additional information). Results of the 
laboratory measurements and information collected are to be submitted to the sponsor on the 
corresponding eCRF. If the medical history of the subject indicates a requirement for other 
assessments not included below, these additional assessments should be completed and 
submitted, as applicable. 
All blood samples should be stored, if possible. If tests are done locally for more rapid results, a 
concurrent sample must also be sent to the central laboratory.

consultation with the hepatologist (as applicable) and UCB responsible physician, as needed.

Other safety measurements 
11.7.1 
12-lead electrocardiogram values 
If a subject develops a clinically relevant ECG abnormality that is confirmed by a repeat ECG 
performed at least 1 hour later, the subject should be excluded from the study. Bazett’s formula 
must be used for correction of QT intervals. 
The ECGs will be centrally read. The investigator will confirm the computerized measurements 
of PR, QRS, QT, and QT interval corrected for heart rate using Bazett’s formula (QTcB) 
intervals (assessed as the mean of 3 to 5 beats). 
11.7.2 
Vital signs 
Vital sign assessments include supine and standing BP measurements and pulse rate. At each 
visit, vital signs will be assessed. The assessment should be taken as follows: The subject should 
initially rest for 2 minutes. While the subject is supine, the BP and pulse rate should be measured 
after 1 minute and then again after 5 minutes (ie, 4 minutes between the 2 measurements). The 
subject should then be asked to stand and the BP and pulse rate should be taken 1 minute and 3 
minutes post standing (ie, 2 minutes between measurements). 
Assessment of orthostatic reaction will be performed at all visits as follows: After the 5-minute 
measurement in supine position, the subject is asked to stand up; BP and pulse rate are measured 
1 and 3 minutes after standing. The 5-minute BP supine values will be compared with the values 
after standing. A drop in systolic BP of ≥20mmHg and/or a drop of ≥10mmHg in diastolic BP 
after 1 and/or 3 minutes in standing position is indicative of orthostatic hypotension. 
Subjects who develop clinically relevant symptomatic hypotension during the course of the study 
should be withdrawn (see Section 6.3). 
11.7.3 
Physical and neurological examinations

The neurological examination may include assessment of mental status, cranial nerves, plantar 
reflexes, deep tendon reflexes, muscle strength, gait, coordination/balance, involuntary 
movements, and sensory perception. 
11.7.4 
Hormone status 
It is recommended that subjects be scheduled for morning appointments to assess hormone status 
(beta-17-estradiol [females only], progesterone [females only], follicle-stimulating hormone 
[FSH], luteinizing hormone [LH], prolactin, triiodothyronin [T3], thyroxine [T4], thyroid-
stimulating hormone [TSH], testosterone [males only], and insulin-like growth factor-1 [IGF-1]). 
However, if morning appointments are not feasible, then subjects should continue to be 
scheduled at approximately the same time of day as all other visits. 
11.7.5 
Modified Minnesota Impulsive Disorders Interview 
The mMIDI has been previously used in Parkinson’s subjects to monitor for development of 
ICDs (Christenson et al, 1994). The mMIDI is applicable for both initial identification of a 
potential ICD and for monitoring ICDs during a clinical study. This mMIDI focuses on the 5 
most common ICDs which may be associated with dopamine agonist use: compulsive buying, 
compulsive gambling, compulsive eating, hypersexuality, and punding (nonsense repetitive 
behavior). The mMIDI will be used only to identify potential impulsive control AEs. The 
mMIDI will be completed according to the schedule of study procedures (Table 5‒1).  
For each of the 5 modules, a gateway question is asked (eg, Do you gamble?). If a gateway 
question is answered “no”, that module ends. Any positive answer after a gateway question 
would affirm the ICD and the subject would move to the next step, which is formal diagnosis 
(referral for a structured clinical interview such as the Structured Clinical Interview for DSM-IV 
Axis II Personality Disorders or other applicable structured clinical interview for the diagnosis of 
ICDs). The instrument should be administered by a physician or a clinical psychologist trained to 
administer the instrument. 
If the subject has a positive mMIDI and a positive structured clinical interview or if the subject 
refuses the structured clinical interview, it would be up to the investigator to determine if the 
subject should be withdrawn from the study. Positive findings from the structured interview must 
be recorded as AEs, and monitored for degree of changes during the study. 
If the subject was referred for a structured clinical interview previously during the study, the 
investigator may use his/her discretion regarding the need to refer the subject for a further 
structured interview.

Menstrual function 
Questions regarding changes in menstrual function in females will be asked.

STUDY MANAGEMENT AND ADMINISTRATION  
12.1 
Adherence to protocol 
The investigator should not deviate from the protocol. However, the investigator should take any 
measure necessary in deviation from or not defined by the protocol in order to protect clinical 
study subjects from any immediate hazard to their health and safety. In this case, this action 
should be taken immediately, without prior notification of the regulatory authority, IRB/IEC, or 
sponsor. 
After implementation of such measure, the investigator must notify the CPM of the sponsor 
within 24 hours and follow any local regulatory requirements. 
12.2 
Monitoring 
Monitoring of the study will be delegated by UCB to a CRO. The CRO will monitor the study to 
meet the CRO’s monitoring Standard Operating Procedures (SOPs), ICH-GCP guideline, and 
applicable regulatory requirements, and to ensure that study initiation, conduct, and closure are 
adequate.  
The investigator and his/her staff are expected to cooperate with UCB (or designee) and to be 
available during the monitoring visits to answer questions sufficiently and to provide any 
missing information. The investigator(s)/institution(s) will permit direct access to source 
data/documents for study-related monitoring, audits, IRB/IEC review, and regulatory 
inspection(s). 
The investigator will allow UCB (or designee) to periodically review all eCRFs and 
corresponding source documents (eg, hospital and laboratory records for each study participant). 
Monitoring visits will provide UCB (or designee) with the opportunity to evaluate the progress 
of the study, verify the accuracy and completeness of eCRFs, ensure that all protocol 
requirements, applicable authorities’ regulations, and investigator’s obligations are being 
fulfilled, and resolve any inconsistencies in the study records. 
For the remote study model, a remote monitoring option is available. All study materials, 
including the ISF, drug accountability records, electronic source documentation, etc will be 
available for remote monitoring with view-only access, with training provided prior to access 
being granted, Study staff will be available to meet via telephone call or telemedicine call. 
12.2.1 
Definition of source data  
All source documents must be accurate, clear, unambiguous, permanent, and capable of being 
audited. They should be made using some permanent form of recording and should not be 
obscured. Photocopies and/or printouts of eCRFs are not considered acceptable source 
documents.  
Source documents, whether paper or electronic, are original records in which raw data are first 
recorded. These may include hospital/clinic/general practitioner records, charts, diaries, x-rays, 
laboratory results, printouts, drug accountability records, care records, ECG or other printouts, 
completed scales, or quality of life questionnaires, for example. Source documents should be 
kept in a secure, limited access area.

Source documents that are computer generated and stored electronically must be available for 
review by the monitor (eg, ECG reports). The technology platform used in this study 
(PLATFORM, see Section 2 for an overview) has multiple levels of functionality, including 
electronic source documentation. All information and data collected in PLATFORM is kept 
securely, with the required privacy measures in place per regulations. 
Electronic data records, such as Holter monitor records or electroencephalogram records, must 
be saved and stored as instructed by UCB (or designee). 
12.2.2 
Source data verification 
Source data verification ensures accuracy and credibility of the data obtained. During monitoring 
visits, reported data are reviewed with regard to being accurate, complete, and verifiable from 
source documents (eg, subject records, recordings from automated instruments, tracings [ECG], 
x-ray films, laboratory reports). All data reported on the eCRF should be supported by source 
documents, unless otherwise specified in Section 12.2.1. 
12.3 
Data handling 
12.3.1 
Case Report form completion 
The investigator is responsible for prompt reporting of accurate, complete, and legible data in the 
eCRFs and in all required reports. 
Any change or correction to the eCRF after saving must be accompanied by a reason for the 
change. 
Corrections made after the investigator’s review and approval (by means of a 
password/electronic signature) will be reapproved by the investigator. 
The investigator should maintain a list of personnel authorized to enter data into the eCRF. 
Detailed instructions will be provided in the eCRF Completion Guidelines. 
12.3.2 
Database entry and reconciliation 
Case Report forms/external electronic data will be entered/loaded into a validated electronic 
database using a clinical data management system (CDMS). Computerized data cleaning checks 
will be used in addition to manual review to check for discrepancies and to ensure consistency of 
the data. Case Report form data are entered into the clinical database using independent, 
double-data entry, with the exception of comment fields, which are verified by a second person. 
The data are entered into the eCRFs once and are subsequently verified if the study is performed 
using electronic data capture. 
An electronic audit trail system will be maintained within the CDMS to track all data changes in 
the database once the data have been saved initially into the system or electronically loaded. 
Regular backups of the electronic data will be performed. 
12.3.3 
Subject Screening and Enrollment log/Subject Identification Code list 
The subject’s screening and enrollment will be recorded as part of the Subject Screening and 
Enrollment log. 
The investigator will keep a Subject Identification Code list. This list remains with the 
investigator and is used for unambiguous identification of each subject.

The subject’s consent and enrollment in the study must be recorded as part of the subject’s study 
record. These data should identify the study and document the dates of the subject’s 
participation. 
12.4 
Termination of the study 
UCB reserves the right to temporarily suspend or prematurely discontinue this study either at a 
single site, multiple sites, or at all sites at any time for reasons including, but not limited to, 
safety or ethical issues, inaccurate or incomplete data recording, noncompliance, or 
unsatisfactory enrollment with respect to quality or quantity. 
If the study is prematurely terminated or suspended, UCB (or its representative) will inform the 
investigators/institutions and the regulatory authority(ies) of the termination or suspension and 
the reason(s) for the termination or suspension, in accordance with applicable regulatory 
requirement(s). The IRB/IEC should also be informed and provided with reason(s) for the 
termination or suspension by the sponsor or by the investigator/institution, as specified by the 
applicable regulatory requirement(s). In addition, arrangements will be made for the return of all 
unused IMP and other material in accordance with UCB procedures for the study. 
12.5 
Archiving and data retention 
The investigator will maintain adequate records for the study, including eCRFs, medical records, 
laboratory results, Informed Consent documents, drug dispensing and disposition records, safety 
reports, information regarding participants who discontinued, and other pertinent data. 
All essential documents are to be retained by the investigator until at least 2 years after the last 
approval of a marketing application in an ICH region and until there are no pending or 
contemplated marketing applications in an ICH region, or at least 2 years have elapsed since the 
formal discontinuation of clinical development of the IMP. These documents should be retained 
for a longer period, however, if required by the applicable regulatory requirement(s) or by an 
agreement with UCB (Committee for Proprietary Medicinal Products [CPMP]/ICH/135/95, 2002 
[Section 4.9.5]). The investigator will contact UCB for authorization prior to the destruction of 
any study records or in the event of accidental loss or destruction of any study records. The 
investigator will also notify UCB should he/she relocate or move the study-related files to a 
location other than that specified in the sponsor’s study master file. 
12.6 
Audit and inspection 
The investigator will permit study-related audits mandated by UCB, after reasonable notice, and 
inspections by domestic or foreign regulatory authorities. 
The main purposes of an audit or inspection are to confirm that the rights and well-being of the 
subjects enrolled have been protected, that enrolled subjects (ie, signing consent and undergoing 
study procedures) are appropriate for the study, and that all data relevant for the evaluation of the 
IMP have been processed and reported in compliance with the planned arrangements, the 
protocol, investigational site, and IRB/IEC SOPs, ICH-GCP, and applicable regulatory 
requirements. 
The investigator will provide direct access to all study documents, source records, and source 
data. If an inspection by a regulatory authority is announced, the investigator will immediately 
inform UCB (or designee).

Good Clinical Practice 
Noncompliance with the protocol, ICH-GCP, or local regulatory requirements by the 
investigator, institution, institution staff, or designees of the sponsor will lead to prompt action 
by UCB to secure compliance. Continued noncompliance may result in the termination of the 
site’s involvement in the study.

STATISTICS 
A description of statistical methods follows and will be described in more detail in the Statistical 
Analysis Plan (SAP). 
13.1 
Definition of analysis sets 
The following analysis sets will be defined: 
• Enrolled Set (ES): all subjects with a signed informed consent form and demographic data. 
• Randomized Set (RS): all subjects from the ES who have been randomized. 
• Safety Set (SS): all subjects from the RS who have at least 1 patch (rotigotine or placebo) 
applied. This population will be used for all safety analyses. 
Full Analysis Set (FAS): all subjects from the SS who have a valid IRLS score and a valid CGI 
Item 1 score at Baseline and a valid post-Baseline IRLS score and a valid post-Baseline CGI 
Item 1 score. This population is the primary population for efficacy analysis.  
• Per Protocol Set (PPS): all subjects from the FAS with no important protocol deviations (as 
specified in the data evaluation meeting) that could affect the co-primary variables and hence 
the efficacy evaluation. This population is the secondary population for efficacy analysis. 
13.2 
General statistical considerations 
Datasets will be analyzed using SAS version 9.4 or higher. 
A complete set of raw data listings containing both, all documented data and all calculated data 
(eg, difference from Baseline) will be generated. In general, summary statistics (n [number of 
available measurements], arithmetic mean, standard deviation [SD], median, minimum, and 
maximum) for quantitative variable and frequency tables for qualitative data will be presented by 
treatment. 
13.3 
Planned efficacy analyses 
13.3.1 
Analysis of the co-primary efficacy variables 
Mean changes from Baseline to the end of the Maintenance Period in IRLS sum score and CGI 
(Item 1) in the 2 rotigotine arms (2mg/24h and 3mg/24h) will be compared with placebo to 
demonstrate superior efficacy of rotigotine. 
The primary analysis of each co-primary variable will be based on a mixed model repeated 
measures (MMRM) analysis of covariance (ANCOVA) that includes terms for treatment group, 
visit, the respective Baseline score, and the interaction between treatment group and visit. The 
model will define patient as a random effect and utilize an unstructured covariance pattern. From 
this MMRM ANCOVA, treatment least-square (LS) means (with 95% confidence intervals [CI]) 
will be calculated and 1-sided 2 sample t-test will be performed (significance level 0.025) to test

the superiority of the rotigotine dose levels versus placebo, starting with 3mg/24h. The 
corresponding p-values will also be calculated. 
The null hypotheses at each dose level are (H0): rotigotine is not superior compared to placebo. 
The alternative hypotheses are (H1): rotigotine is superior to placebo. Both co-primary endpoints 
must demonstrate significant results (at significance level 0.025) to demonstrate superiority of 
this dose level of rotigotine over placebo. 
If the 3mg/24h dose is successful, the 2mg/24h dose level will be tested in the same way. Since 
both hypotheses have to be rejected in order to continue, multiplicity adjustment is not needed 
for the 2 hypotheses at each dose level. The multiplicity based on the two dose levels will be 
covered by applying the hierarchical approach (closed test procedure). 
For subjects who prematurely withdraw for any reason before end of Maintenance, data collected 
during the Withdrawal Visit will be used to impute measurements at the next consecutive visit. 
IRLS or CGI-1 measurements must be performed no longer than 1 day after the last patch 
removal to be utilized for analysis (valid measurements). 
The above analyses will be performed on the FAS and the PPS. The primary analysis will be 
considered the analysis on the FAS. 
13.3.2 
Analysis of the secondary efficacy variable 
For the secondary variables change from Baseline to end of the Maintenance Period in CGI Item 
1 and RLS-6 an ANCOVA will be performed as described for the analysis of the primary 
variable, however PPS analyses will not be performed.  
13.3.3 
Other efficacy variables 
The other efficacy variables listed will be analyzed in a descriptive manner. Summary statistics 
will be provided, statistical tests comparing rotigotine arms with placebo will be performed and 
the corresponding p-values will be provided for descriptive purposes only. 
• Change from Baseline in CGI Item 1 by visit*  
• Change from Baseline in RLS-6 Rating Scales by visit* 
• Change from Baseline in IRLS sum score by visit* 
• IRLS Responder by visit 
• IRLS Remitter by visit and by definition (see previous) 
• CGI scale Item 1 Responder 
• *For the IRLS, CGI, and RLS-6 the EoM Visit is already covered under primary and 
secondary variables.  
13.4 
Planned safety and other analyses 
All analyses for safety and other non-efficacy variables will be performed using the subjects in 
the SS.

Safety analyses 
Adverse events will be reported in frequency tables as the number and percentage of subjects 
reporting TEAEs by treatment group. Additionally, frequency tables for serious TEAEs, non-
serious TEAEs, TEAEs leading to discontinuation of study medication, TEAEs by intensity and 
TEAEs by relationship to treatment will be provided by treatment group. 
Descriptive statistics on change from Baseline in laboratory data, including hormone status, will 
be summarized by visit and treatment group. Post-Baseline clinical significant abnormalities will 
be presented by treatment group. 
Vital signs variables and their change from Baseline will be presented using descriptive statistics 
by visit and treatment group. The number and percentage of subjects meeting orthostatic 
hypotension criteria will also be presented. 
ECG and its change from Baseline will be presented using descriptive statistics by visit and 
treatment group. The number and percentage of subjects with post-Baseline clinical significant 
abnormalities will be presented by treatment group. 
Body weight, height, and BMI and their change from Baseline will be presented using 
descriptive statistics by visit and treatment group. Clinically significant values will be reported. 
13.4.2 
Other analyses 
Prior and concomitant medication as well as medical history will be summarized using frequency 
tables. Demographic and baseline characteristics will be summarized using descriptive statistics. 
Plasma concentration of unconjugated rotigotine will summarized by dose levels and visit. In 
addition, these concentrations may be used for population PK-PD analyses. 
Summary statistics for Subject Quality of Life Questionnaire will be provided. 
13.5 
Handling of protocol deviations 
Important protocol deviations are deviations from the protocol which potentially could have a 
meaningful impact on study conduct or on the primary efficacy, key safety, or PK/PD outcomes 
(if applicable) for an individual subject. The criteria for identifying important protocol deviations 
will be defined within the appropriate protocol-specific document. Important protocol deviations 
will be reviewed as part of the ongoing data cleaning process and data evaluation. All important 
deviations will be identified and documented prior to unblinding to confirm exclusion from 
analysis sets. 
13.6 
Handling of dropouts or missing data 
Rules for imputation of missing data will be detailed in the SAP. 
No imputation will be implemented for missing values in other efficacy variables or safety 
variables. However, rules for date imputations to allow the derivation of variables (eg, age and 
TEAEs) will be implemented. 
Dropouts will not be replaced during the course of the study.

Planned interim analysis and data monitoring 
An interim analysis for futility will be performed with approximately 33% of the planned 
number of evaluable subjects; recruitment will not be stopped for the interim analysis. The 
interim analysis will have three possible outcomes: 
• Stop the study early for futility because rotigotine treatment at 3mg/24h meets the futility 
criteria (ie, no demonstrated benefit between active treatment and placebo to be expected at 
final analysis) regarding the primary objective of the study 
• Stop recruitment into the rotigotine 2mg/24h arm for futility because rotigotine treatment at 
2mg/24h seems futile regarding the primary objective of the study, 
• Continue the study as planned. 
No further changes to the protocol (eg, sample size adjustment) will be made as a result of the 
interim analysis. 
The interim analysis will be conducted as soon as the end of the Maintenance/Premature 
Withdrawal Visit has been documented for 45 evaluable patients. The interim analysis will be 
performed on the data for the primary efficacy variable IRLS only and CGI Item 1 will not be 
considered. In case futility is achieved for the IRLS, this would also hold true for the CGI, since 
a lower effect size index for CGI is anticipated. 
In the interim analysis, the change from Baseline to the end of the Maintenance Period in the 
score of the IRLS will be investigated. Estimates of treatment effect will be obtained separately 
for the two active treatment arms and Placebo from an MMRM ANCOVA model as described in 
Section 13.3.1. Furthermore, the conditional power under the anticipated effect (anticipated 
effect and standard deviation will be utilized) according to Lan and Wittes (Siu and Lan, 2001) 
will be calculated for each of the treatment arms. The conditional power under the anticipated 
effect refers to the probability of concluding a positive result on the IRLS at the end of the study, 
assuming that the assumptions for the sample size estimation holds true. 
The continuation criterion for each treatment arm is defined as applying both of the following 
conditions regarding the change from Baseline to the end of the Maintenance Period in the score 
of the IRLS: 
• Treatment difference between the respective active group and placebo ≥2.0 points  
• Conditional power under anticipated effect ≥60 % 
If at least 1 of these conditions fails, the continuation criterion is not met. Table 13‒1 shows the 
possible outcomes of the interim results and the corresponding decision rules.

Continue the study as planned (with 3mg/24h and

The interim analysis will be performed by an independent unblinded statistician not involved in 
any other study activity. Access to the interim results will be restricted to the statistician 
performing the analysis. 
The study team will remain blinded and will be informed of the decision (stop the study early, 
stop a dose arm or continue the study as planned) without any supporting information. Details of 
the analysis will only be disclosed to the sponsor after study unblinding and will be provided in 
the clinical study report. 
13.8 
Determination of sample size 
The sample size estimate is based on the efficacy results observed in the adult RLS Phase 3 
confirmatory study SP792, which was conducted in the USA. In this study, a range of rotigotine 
doses were compared to placebo. 
The sample size calculation assumes that adolescent and adult patients will show a similar effect 
of rotigotine with respect to IRLS score and CGI (item 1) changes from Baseline in comparison 
to placebo, with a similar proportion of patients not included in the primary analysis. 
In the adult study, the observed difference between the 3mg/24h rotigotine group and placebo in 
the change from Baseline to end of the 3-month Maintenance Period in IRLS sum score was 5.9. 
Already a difference between rotigotine and placebo of 4.0 points can be considered as clinically 
relevant. The common Standard Deviation (SD) estimate in the adult study was 7.9. For the CGI 
(Item 1), the difference between 3mg/24h rotigotine group and placebo was 0.6 with a SD of 1.2. 
With these assumptions, a sample size of 45 evaluable patients in each group will provide a 
power of 93% for the IRLS endpoint, and a power of 87% for the CGI (Item 1) endpoint in the 
3mg/24h dose. Assuming independence of the 2 endpoints will result in a power of 80% for the 
analysis of the co-primary variables. Since it is known that the 2 endpoints will have a relatively 
high correlation (approximately 0.7), the calculated 80% is a conservative estimator for the 
power. 
Assuming similar effects for the 2mg/24h dose group, the conditional power for the 2mg/24h 
dose group is also 80% with an overall power for the study >60%. To obtain 135 evaluable 
subjects (ie, FAS), 138 patients have to be randomized (assuming approximately 2% of the 
randomized subjects cannot be utilized).

Prior to obtaining informed consent, information should be given in a language and at a level of 
complexity understandable to the subject in both oral and written form by the investigator (or 
designee). Each subject will have the opportunity to discuss the study and its alternatives with 
the investigator. 
For those subjects who are assessed as preliminarily eligible per the IRB-approved prescreening 
script, contact information will be collected, including a valid email address of the subject/legal 
representative (eg, parent or guardian). A secure link to the eConsent web portal will be sent via 
email, along with unique login credentials. The subject/legal representative will receive a prompt 
to change the temporary assigned password upon first login. The informed consent materials will 
be presented in the eConsent portal through an electronic rendition of the IRB-approved consent 
documents. The study investigator and/or designated staff will complete the informed consent 
process with the subject/legal representative by telephone. Subjects who agree to take part in the 
study will provide their handwritten signature using a computer mouse, touchscreen, or stylus on 
a computer or tablet in the designated signature block; the legal representative will complete the 
handwritten signature in the same manner; and the consenter will countersign. If a legal 
representative agrees for the adolescent to take part in the study, but the adolescent does not wish 
to participate, then he or she cannot be enrolled. 
The subject or his/her legal representative must receive a copy of the signed and dated Informed 
Consent form. As part of the consent process, each subject must consent to direct access to 
his/her medical records for study-related monitoring, auditing, IRB/IEC review, and regulatory 
inspection. 
If the Informed Consent form is amended during the study, the investigator (or the sponsor, if 
applicable) must follow all applicable regulatory requirements pertaining to the approval of the 
amended Informed Consent form by the IRB/IEC and use of the amended form. 
All studies conducted in the United States must include the use of a Health Insurance Portability 
and Accountability Act Authorization form. 
The subject may withdraw his/her consent to participate in the study at any time. A subject is 
considered as enrolled in the study when he/she has signed the Informed Consent form. An eCRF 
must not be started, nor may any study specific procedure be performed for a given subject, 
without having obtained his/her written consent to participate in the study. 
14.2 
Subject identification cards 
Upon signing the Informed Consent and Assent form (as applicable), the subject or legal 
representative will be provided with a subject identification card in the language of the subject. 
The investigator will fill in the subject identifying information and medical emergency contact 
information. The investigator will instruct the subject to keep the card with him/her at all times. 
14.3

The investigator/UCB will ensure that an appropriately constituted IRB/IEC that complies with 
the requirements of the current ICH-GCP version or applicable country-specific regulations will 
be responsible for the initial and continuing review and approval of the clinical study. Prior to 
initiation of the study, the investigator/UCB will forward copies of the protocol, Informed 
Consent form, Investigator’s Brochure, investigator’s curriculum vitae (if applicable), 
advertisement (if applicable), and all other subject-related documents to be used for the study to 
the IRB/IEC for its review and approval. 
Before initiating a study, the investigator will have written and dated full approval from the 
responsible IRB/IEC for the protocol. 
The investigator will also promptly report to the IRB/IEC all changes in the study, all 
unanticipated problems involving risks to human subjects or others, and any protocol deviations, 
to eliminate immediate hazards to subjects. 
The investigator will not make any changes in the study or study conduct without IRB/IEC 
approval, except where necessary to eliminate apparent immediate hazards to the subjects. For 
minor changes to a previously approved protocol during the period covered by the original 
approval, it may be possible for the investigator to obtain an expedited review by the IRB/IEC as 
allowed. 
As part of the IRB/IEC requirements for continuing review of approved studies, the investigator 
will be responsible for submitting periodic progress reports to the IRB/IEC (based on IRB/IEC 
requirements), at intervals appropriate to the degree of subject risk involved, but no less than 
once per year. The investigator should provide a final report to the IRB/IEC following study 
completion. 
UCB (or its representative) will communicate safety information to the appropriate regulatory 
authorities and all active investigators in accordance with applicable regulatory requirements. 
The appropriate IRB/IEC will also be informed by the investigator or the sponsor, as specified by 
the applicable regulatory requirements in each concerned country. Where applicable, 
investigators are to provide the sponsor (or its representative) with evidence of such IRB/IEC 
notification. 
14.4 
Subject privacy 
UCB staff (or designee) will affirm and uphold the subject’s confidentiality. Throughout this 
study, all data forwarded to UCB (or designee) will be identified only by the subject number 
assigned at Screening. 
The investigator agrees that representatives of UCB, its designee, representatives of the relevant 
IRB/IEC, or representatives of regulatory authorities will be allowed to review that portion of the 
subject’s primary medical records that directly concerns this study (including, but not limited to, 
laboratory test result reports, ECG reports, admission/discharge summaries for hospital 
admissions occurring during a subject’s study participation, and autopsy reports for deaths 
occurring during the study).

APPENDICES 
17.1 
Protocol Amendment 1 
Rationale for the amendment 
The main purpose of this substantial amendment was to change the ferritin level at 
Visit 1/Screening from <50ng/mL to below the lower limit of normal.  
Other changes included in this amendment are as follows: 
• Sponsor contact information has been updated. 
• Added headings for primary and other safety variables. Clarified that AEs are treatment 
emergent. Categorized occurrence of TEAEs and TEAEs leading to withdrawal as primary 
safety variables. The remaining safety variables were categorized as other.  
• Changed the eC-SSRS to the C-SSRS. 
• Addition of urine drug screen at Unscheduled Visits. 
• Clarified that the smartphone technology will be used in combination with visits from mobile 
study personnel to subjects’/legal representatives’ homes. Visits to local health care providers 
or Patient Service Centers will not be conducted during this study. 
• Clarified that a serum pregnancy test is to be performed in females at Screening and urine 
pregnancy test at all other visits. A positive urine pregnancy test must be confirmed by a 
serum pregnancy test. 
• Added a description of the Where’s My Patch (WMP) app. 
• Removed BMI of <95th percentile for his or her age group, according to the Child and Teen 
BMI calculator as Inclusion Criterion #5. 
• Clarified that the washout period for supplemental iron is 1 month prior to Baseline in 
Exclusion Criterion #10a. 
• Added secondary RLS (eg, due to renal insufficiency [uremia], iron deficiency, or 
rheumatoid arthritis as Exclusion Criterion #13. 
• Added a lifetime history of suicide attempts or suicidal ideation in the past 6 months as 
indicated by a positive response (“Yes”) to either Question 4 or Question 5 of the C-SSRS at 
Screening as Exclusion Criterion #14. 
• Added taking a prohibited concomitant medication and the washout period as Exclusion 
Criterion #15. 
• Clarified that subjects who have been screened but not randomized may be rescreened with 
the permission of the Study Physician or representative. 
• Added RBC indices (mean corpuscular hemoglobin; mean corpuscular hemoglobin 
concentration; mean cell volume; cell distribution width) to the laboratory measurements. 
• Typographic errors and changes of an editorial nature were made.

Section 5.1, Study description 
Second, third, and fourth paragraphs 
The study will be conducted using the remote study model, which uses telemedicine technology 
(ie, NORA, see Section 2 for an overview) for interactions between the investigator/study staff 
and study subjects/legal representatives. Additionally, subjects/legal representatives will visit 
local healthcare facilities, such as local healthcare provider’s offices/clinics and local Patient 
Service Centers, to complete designated study procedures (eg, neurological exams, physical 
exams, and ECGs with local healthcare providers; lab collections and vital signs at Patient 
Service Centers). As an alternative option to Patient Service Centers, mobile study personnel 
may visit subjects’/legal representatives’ homes to complete certain study procedures. 
The study will begin with a Screening Period of at least 7 days (maximum of 28 days) prior to 
Visit 2/Baseline to ensure homogeneous baseline conditions can be established for all subjects. 
Subjects with prior intake of any dopamine agonists must discontinue therapy at least 14 days 
prior to Visit 2/Baseline. Subjects taking L-dopa must discontinue therapy at least 7 days prior to 
Visit 2/Baseline. 
The Screening Period will be followed by the Titration Period. Subjects will receive their first 
dose of study medication following Baseline at Visit 3/Day 1. Subjects will be initiated either on 
placebo or 1mg/24h rotigotine. The dose of rotigotine taken by subjects randomized to rotigotine 
will then be up-titrated on a weekly basis by 1mg/24h at a time to 2mg/24h or 3mg/24h, 
depending on the subject’s assigned dose level.

representatives’ homes to complete certain study procedures (eg, neurological exams, physical 
exams, ECGs, lab collections, and vital signs). 
The study will also utilize a reminder app to help maximize retention of study subjects and limit 
dropouts. The app, located on the study smartphone, called Where’s My Patch (WMP) will help 
encourage subject adherence to study medication administration by reminding them to place 
patches at their prespecified time each day. It also provides a body map to record daily patch 
locations as a visual reminder of where patches have already been placed over the past 14 days 
and to facilitate patch site rotation. Patch location data will only be retained locally on the 
smartphone and then automatically deleted after 14 days. Subject use of the MWP app will be 
encouraged, but not required. 
The study will begin with a Screening Period of at least 7 days (maximum of 28 days) prior to 
Visit 2/Baseline to ensure homogeneous baseline conditions can be established for all subjects. 
Subjects with prior intake of any dopamine agonists must discontinue the therapy at least 14 days 
prior to Visit 2/Baseline. Subjects taking L-dopa must discontinue the therapy at least 7 days 
prior to Visit 2/Baseline. Discontinuation of therapy must be driven by the subject’s medical 
needs and not undertaken with the purpose of making a potential subject eligible for this study. 
The Screening Period will be followed by the Titration Period. Subjects will receive their first 
dose of study medication at Visit 3/Day 1. Subjects will be initiated either on placebo or 
1mg/24h rotigotine. The dose of rotigotine taken by subjects randomized to rotigotine will then 
be up-titrated on a weekly basis by 1mg/24h at a time to 2mg/24h or 3mg/24h, depending on the 
subject’s assigned dose level.

As part of the remote study model, the study site will provide study medication and all required 
supplies via direct-to-subject shipments. Once eligibility is confirmed, the study site will contact 
the interactive response technology (IRT) for randomization assignment, and shipments will be 
prepared and sent out for delivery to the subject’s/legal representative’s home/preferred address. 
Shipments will be confirmed as delivered by the study staff, with appropriate documentation in 
the subject’s study records. The study medication will be confirmed as received in good 
condition and within the acceptable temperature range (ie, fit for use). A telemedicine call will 
be completed to instruct the subject/legal representative on the correct storage and administration 
of the study medication, which will also be documented as part of subject’s study record.

Section 7.6, Drug accountability 
First and third paragraphs 
At the designated timepoints during the study, subjects/legal representatives will return to the 
study site the unused study medication patches remaining as part of the medication kits, along 
with the kit itself, via the return shipment materials provided. A Drug Accountability form will 
be used to record IMP dispensing and return information on a by subject basis and will serve as 
source documentation during the course of the study. Details of any IMP lost, damaged (due to 
breakage or wastage), not used, disposed of at the study site, or returned to the sponsor or 
designee must also be recorded on the appropriate forms. All supplies and drug accountability 
documentation must be made available throughout the study for UCB (or designee) to review. 
The investigator may assign some of the investigator’s duties for drug accountability at the study 
site to an appropriate designee.
