Exploratory Endpoints:
The following exploratory endpoints will be assessed in Part A (Day 1, Titration, and 
Maintenance):
 
 
 
 
 
 
 
 
 
General Design and Methodology:
This is an open-label, single-arm study that includes a 2-week, double-blind, placebo-controlled, 
randomized drug withdrawal period followed by a 3-week blinded re-titration period in which 
patients with tics associated with TS may be eligible to participate after successful completion of 
any of the parent studies (SD-809-C-17 [Phase 1b], TV50717-CNS-30046 [Phase 2/3], or 
TV50717-CNS-30060 [Phase 3]). Patients rolling over from Study SD-809-C-17 will need to 
undergo all day 1 assessments. For patients rolling over from Study TV50717-CNS-30046 or 
Study TV50717-CNS-30060, the week 13 visit (Study TV50717-CNS-30046) or the week 9 visit 
(Study TV50717-CNS-30060) will be the day 1 visit for Study TV50717-CNS-30047. If the 
patient does not wish to enroll in Study TV50717-CNS-30047 at that visit, they can enroll up to 
1 week following the week 13 or week 9 visits, respectively. The end of study is defined as the 
date of the week 56 visit of the last participant.
Patients who have successfully completed a parent study may be eligible to enroll in this study 
after they complete a 1-week washout period and the final evaluation at week 13 (TV50717-
CNS-30046) or week 9 (TV50717-CNS-30060) in the parent study. 
Site-administered scales include the YGTSS, 
, Mini International Neuropsychiatric 
Interview For Children and Adolescents (MINI Kid, version 6.0), and the C-SSRS; and 
self-administered scales include the TS-PGII, 
, 
, CDI-2, and 
C&A-GTS-QOL. For the YGTSS, input from the caregiver/adult is required. For 
 
TS-PGII 
, input from the caregiver/adult is permitted. For all other scales, for 

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
13
children 13 years of age and under, interviews may be performed separately or jointly with the 
caregiver/adult as appropriate or as defined by the scale. For children over 13 years of age, 
caregiver/adult involvement is strongly encouraged. Questions should be directed to the child, 
but the caregiver/adult should be encouraged to add relevant information. It should be noted that 
the CDI-2 has individual parent and child questionnaires.
Informed consent/assent, depending on the child’s age, as appropriate, will be obtained before 
any study procedures are performed. For patients rolling over from Study TV50717-CNS-30046 
or Study TV50717-CNS-30060, informed consent/assent, as appropriate, may be obtained prior 
to the day 1 visit, up to 4 weeks in advance of open-label study participation. Any patient that 
turns 18 years of age during the course of Study TV50717-CNS-30047 will need to be 
re-consented as an adult.
In the study period descriptions below, “week X” refers to the end of that week, which coincides 
with the study visit, unless stated otherwise. Some dose changes will occur at the start of a week 
rather than at the end of a week and will be indicated as such.
Screening 
For patients from Study SD-809-C-17:
During the screening period (up to 31 days), all screening procedures will be performed for 
patients rolling over from Study SD-809-C-17 as they will have been off IMP for several months 
at the time of enrollment into this study. 
After informed consent/assent, depending on the child’s age, as appropriate, is obtained, patients 
who are stable from a medical and psychiatric standpoint will undergo a screening evaluation, 
including medical history, physical and neurological examination, assessment of vital signs, 
laboratory testing, and 12-lead ECG, along with rating scales to assess comorbid TS symptoms 
and behavioral status.
At the discretion of the investigator, the screening visit may be divided into 2 visits if the visit 
length is deemed to be too burdensome for the patient. Patients may be rescreened 1 time if there 
is a change in the patient’s medical background, a modification of study entry criteria, or other 
relevant change. (Note: Details of rescreening must be approved and documented by the medical 
monitor and/or Clinical Surveillance and Training team.) For patients from Study TV50717-
CNS-30046 or Study TV50717-CNS-30060:
The screening evaluation for this open label study occurs at the end of the treatment period in the 
double-blind study. To reduce patient burden and not collect duplicate information, after 
obtaining informed consent/assent, depending on the child’s age, as appropriate, relevant data 
collected in Study TV50717-CNS-30046 or Study TV50717-CNS-30060 will be used to provide 
corresponding data in this open-label study (see Table 1).
YGTSS Rater Certification: All investigators and subinvestigators who will be administering the 
YGTSS from screening through the end of study visit must undergo and pass a Rater 
Certification Program which will be provided separately from this protocol. Every effort must be 
made to ensure that the same certified rater administers the YGTSS to a specific patient at all 
visits where this scale is administered, especially at day 1 and at weeks 28, 30, and 54/early 
termination visits. However, if due to unforeseen circumstances the same rater is absolutely 
unavailable to complete a visit rating, the YGTSS can be administered only by another certified 
individual from that study site.

Part A: 
Day 1 visit (all patients): For patients rolling over from Study TV50717-CNS-30046 or 
Study TV50717-CNS-30060, the week 13 visit (Study TV50717-CNS-30046) or the week 9 visit 
(Study TV50717-CNS-30060) will be the day 1 visit for Study TV50717-CNS-30047. Patients 
rolling over from Study SD-809-C-17 will need to undergo all day 1 assessments. Day 1
assessments for Study TV50717-CNS-30047 that are identical to Study TV50717-CNS-30046 
week 13 or Study TV50717-CNS-30060 week 9 visit assessments do not need to be repeated.
Additionally, Study TV50717-CNS-30047 required evaluations will be completed at 
Study TV50717-CNS-30046 week 13 visit or Study TV50717-CNS-30060 week 9 visit (see
Table 1). For all patients, the day 1 visit should occur on or as close as possible to the week 13 or 
week 9 visit from Study TV50717-CNS-30046 and Study TV50717-CNS-30060, respectively, 
but not >7 days beyond those respective visits.
For patients with clinically significant laboratory abnormalities at week 12 in Study TV50717-
CNS-30046 or at week 8 in Study TV50717-CNS-30060, week 13 values (Study TV50717-
CNS-30046) or week 9 values (Study TV50717-CNS-30060) will serve as day 1 laboratory 
values in this study. 
Titration period (7 weeks): As patients from Study SD-809-C-17 will have been off IMP for 
several months at the time of enrollment, and since patients from Study TV50717-CNS-30046 or 
Study TV50717-CNS-30060 will have discontinued IMP (TEV-50717 or placebo) for at least 
1 week at completion of the parent study, all patients will undergo TEV-50717 dose titration in 
this study. Patients will receive 6 mg of TEV-50717 with food on the evening of day 1. Tablets 
should be taken with food (eg, a snack) and should not be taken on an empty stomach. The 
titration scheme and maximum dose will be determined by body weight and cytochrome P450 
2D6 (CYP2D6) impairment status from the parent study. Patients will be classified as CYP2D6 
impaired if they are receiving a strong CYP2D6 inhibitor or are a CYP2D6 poor metabolizer 
based on blinded assessment of CYP2D6 genotype at baseline of the parent study. Patients who 
are CYP2D6 impaired will have a dose cap in the open-label trial, as shown in the table below. 
Patients and their caregiver/adult will interact weekly with the clinical research staff, either by 
telephone contact or in-clinic visits from week 1 through week 7 of the titration period, in order 
to evaluate safety and establish a dose of TEV-50717 that optimally reduces tics and is well 
tolerated (optimal dose). Safety evaluations during the titration period include assessment of vital 
signs, monitoring for adverse events and concomitant medications, 12-lead ECGs, and rating 
scales for depression and suicidality. 
In-person (in-clinic) study visits will be scheduled at weeks 2, 4, and 6, and telephone contacts 
will be scheduled for weeks 1, 3, 5, and 7 in order to assess tic severity and adverse events. 
The dose of the IMP should be increased on a weekly basis until one of the following occurs:

The investigator determines there has been a clinically meaningful reduction in tics.

The patient experiences a protocol-defined “clinically significant” adverse event 
(defined as an adverse event that is related to the IMP and is either moderate or severe 
in intensity or meets the criteria for a serious adverse event).

The maximum allowable dose is reached based on the patient’s weight and CYP2D6 
impairment status.

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
15
If a stable dose is reached before the week 7 telephone call, the patient should continue on that 
dose (ie, the dose should not be increased further) for the remainder of the titration period. If a 
patient experiences depression, suicidal ideation or behavior, anxiety, akathisia, parkinsonism, 
somnolence, any other adverse event that interferes with daily activity, or adverse event that is 
related to IMP, the investigator will determine if a dose reduction or suspension is necessary. If 
the patient requires a dose reduction or suspension during a telephone contact, an unscheduled
in-clinic visit should be conducted as soon as practicable thereafter.
Dose adjustments should be made based on all available information, including the patient and 
caregiver/adult reports of adverse events and tic reduction, the clinical assessment of safety and 
efficacy by the investigator, and the information from rating scales.

Maintenance period: At the end of the titration period, the patient’s initial dose for the 
maintenance period will be established. Dose adjustments of TEV-50717 (upward or downward) 
may be made during the maintenance period, if necessary, but not more often than every 5 days 
and only in increments of 6 mg. As during titration, dose adjustments should be made based on 
all available information.
During the maintenance period, in-person (in-clinic) study visits will be scheduled at weeks 8, 
15, 34, 41, and 54 for assessments of safety and efficacy and telephone contacts will be 
scheduled for weeks 21 and 47 in order to assess adverse events and tic severity. The randomized 
drug withdrawal and re-titration period (Part B) will occur from the end of week 28 through the 
end of week 33, and then the Part A maintenance period will resume, along with the ability to 
make dose adjustments as described above. At week 54, patients will undergo a complete 
evaluation, including physical and neurological examination, safety laboratory testing, 12-lead 
ECG, CDI-2, and C-SSRS assessments, as well as the YGTSS, TS-CGI, 
, TS-PGII, 
, and C&A-GTS-QOL. 
Washout and follow-up period: All patients will discontinue IMP at the week 54 visit and will 
return 1 week later (week 55) for evaluation of safety and tic reduction. Patients will have a 
follow-up telephone contact for safety evaluation 1 week after the end of the washout period 
(2 weeks after their last dose of IMP) (week 56).
Part B: Blinded, Randomized Drug Withdrawal Period and Titration Post-Drug Withdrawal 
(5 weeks): At the week 28 visit, the patients will be randomized 2:1 to their current dose of 
TEV-50717 or placebo in order to check for the return of symptoms. Because IMP is dispensed 
as enough doses for 2 weeks (current dose level and next dose level), the week 28 visit 
(Day 196) is considered the first day of the randomized withdrawal period, although the patient 
will begin taking blinded IMP the next morning on Day 197. Patients will have a follow-up 
telephone contact for safety evaluation 1 week after the start of the randomized drug withdrawal 
period. At week 30, safety and efficacy will be assessed. At the week 30 visit, patients who 
receive TEV-50717 during the randomized drug withdrawal period will continue at the same
dose in a blinded manner from the start of week 31 to the start of week 34. Any patient who was 
randomized to placebo during the 2-week randomized drug withdrawal period will undergo 
blinded re-titration (titration post-drug withdrawal) to their previously established maintenance
dose over the 3 weeks of treatment following the randomized drug withdrawal period (start of 
week 31 through start of week 34 [Days 211 through 232]). The titration scheme and maximum 
dose will be determined based on the previously established maintenance dose as tabulated 
below. The dose of IMP for each patient who underwent 2 weeks of placebo will be titrated back 
to the maintenance dose that was used by the patient up to week 28 followed by continued 
maintenance therapy at that dose. Patients will have a follow-up telephone contact for safety 
evaluation at weeks 31 and 33. All patients should be back at their maintenance dose on or 
before the start of week 34 and return to open-label treatment for the remainder of the study
(note that, because IMP is dispensed for 2-week periods, patients will use blinded bottles through 
the end of week 34; however, all patients will be known to be on active treatment at the start of 
week 34).

a The previously established maintenance dose is the dose administered at the end of Part A (Day 196 [end of 
week 28]). The blinded, randomized drug withdrawal period will occur from the start of week 29 through the end 
of week 30.
IMP=investigational medicinal product.
Method of Randomization and Blinding: This is an open-label study that includes a 2-week
double-blind, placebo-controlled, randomized drug withdrawal period followed by a 3-week 
blinded re-titration period (note that, because IMP is dispensed for 2-week periods, patients will 
use blinded bottles for an additional 1 week [4 weeks total after the end of the blinded, 
randomized withdrawal period]; however, all patients will be known to be on active treatment 
during that week). During the blinded drug withdrawal and re-titration period, patients and 
investigators will remain blinded to treatment assignment. In addition, the sponsor’s and 
development partner’s clinical personnel and all vendors (with the exception of the Interactive 
Response Technology (IRT) vendor and the IMP packaging vendor) involved in the study will be 
blinded to the IMP identity until the database has been locked for analysis and the treatment 
assignments are revealed.
IMP Dose, Mode of Administration, and Administration Rate:
IMP will be administered as oral tablets at a starting dose of 6 mg once daily, to be taken in the 
morning (except for day 1, when it should be taken in the evening after the clinic visit). Titration 
schemes based on body weight are shown in the first table above (“Titration period [7 weeks]”
section). The maximum daily dose is determined by body weight and CYP2D6 impairment status 
(see the first table above). Dose adjustments can be made during the titration period and also, if 
clinically indicated, during the maintenance period dosing before and after the randomized drug 
withdrawal and re-titration period.
During the open-label period, TEV-50717 tablets are available in the following dose strengths: 6, 
9, and 12 mg. Each dose strength will have a marking of SD 6, SD 9, and SD 12 corresponding 

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
18
to the dose strength and a distinct color: 6 mg – purple, 9 mg – blue, and 12 mg – beige. IMP
will be supplied in 20-or 60-count tablets per dose strength per bottle.
During the randomized drug withdrawal and re-titration period, TEV-50717 tablets are available 
in the following dose strengths: 6, 9, 12, 15, and 18 mg, all of which are identical in size, shape, 
and color (white). The IMP will be supplied in 20-count bottles. The placebo tablets and 
packaging will match those for TEV-50717. 
Patients who receive TEV-50717 during the randomized drug withdrawal period will remain on 
their maintenance dose of blinded active IMP from the start of week 31 to the start of week 34; 
those assigned to placebo during the randomized drug withdrawal period will undergo blinded 
re-titration from the start of week 31 to the start of week 34 back to their previously established 
maintenance dose from the end of week 28. Note that, because IMP is dispensed for 2-week 
periods, patients will use blinded bottles through the end of week 34; however, all patients will 
be known to be on active treatment at the start of week 34. 
IMP will be administered as follows:

IMP should be swallowed whole and taken with food. Tablets should be taken with 
food (eg, a snack) and should not be taken on an empty stomach.

Dosing will be based on body weight and strong CYP2D6 impairment status, as 
shown in the tables above.

The starting dose is 6 mg in all patients. With the exception of the 6-mg dose 
(administered once daily), doses will be administered twice daily, approximately 
8 to 10 hours apart during the day. A minimum of 6 hours should elapse between 
doses. If a patient misses a dose and it is within 6 hours of their next dose, the missed 
dose should be skipped. 

After week 1, dose increases may not occur more frequently than every 5 days.

Dose reductions, if required, should be in increments of 6 mg. If more than 1 dose 
reduction is required for an adverse event, the medical monitor should be 
notified.

After dose adjustment, if the maintenance dose for a patient is 6 mg, the dose should 
be taken once a day in the morning with food.

During the titration period, the dose of IMP should be adjusted according to the first 
table above (Maximum Daily Dose of IMP by Study Day and Weight Category on 
Day 1 for Titration at Study Initiation) to identify a dose level that optimally reduces 
tics and is well tolerated. A dose cap for impaired patients is prespecified by the IRT.

After week 24, patient dose should be kept stable, if possible, until beginning Part B.

During the randomized drug withdrawal period, the patient will continue to receive 
their current dose of TEV-50717 or receive matching placebo until returning to their 
dose of TEV-50717 at the start of week 31 (patients who receive TEV-50717 during 
the randomized drug withdrawal period will remain on their maintenance dose of 
blinded active IMP from the start of week 31 to the start of week 34; those assigned 
to placebo during the randomized drug withdrawal period will undergo blinded re-

Allowed and Prohibited Medications before and during the Study: 
See Appendix A for details of allowed and disallowed medications. 
Statistical Considerations:
Sample Size Rationale: This is an open-label study. The sample size for this study is not based 
on statistical considerations; hence, only descriptive statistics will be presented and will be 
analyzed by age group at baseline. Up to approximately 227 patients who also meet patient 
exclusion/inclusion criteria will be enrolled (approximately 1 patient is estimated to enroll from 
the Phase 1b Study SD-809-C-17, up to approximately 99 patients are estimated to enroll from the 
Phase 2/3 Study TV50717-CNS-30046, and up to approximately 127 patients are estimated to 
enroll from the Phase 3 Study TV50717-CNS-30060).
For the randomized drug withdrawal period, 190 patients to be included in the analysis will 
provide approximately 90% power to detect a difference between TEV-50717-treated and 
placebo-treated patients assuming a difference in YGTSS TTS of 4.5 with a standard deviation of 
9 using a two-sided test for difference at a significance level of 0.05.
Planned Interim Analysis:
When approximately 100 patients have completed the 28-week clinic visit, an interim analysis,
including data from day 1 and up to week 28 visit only, will be conducted to provide descriptive, 
long-term safety and efficacy data to be used in regulatory submissions. To maintain data 
integrity of Study TV50717-CNS-30047, only a limited number of personnel who do not have 
contact with the sites will have access to this interim data in preparation for the regulatory filing.

Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
24
As no decisions regarding conduct of the study will be made based on the descriptive interim 
analysis, no alpha will be spent.
Analyses of Safety: All adverse events will be coded using the Medical Dictionary for 
Regulatory Activities. Each patient will be counted only once in each preferred term or system 
organ class category for the analyses of safety. Summaries will be presented for all adverse 
events, adverse events determined by the investigator to be related to IMP, serious adverse events, 
and adverse events causing withdrawal from the study. Patient listings of serious adverse events 
and adverse events leading to withdrawal will be presented.
Observed values and changes from day 1 in laboratory results and vital signs will be summarized 
descriptively. 
Observed values in ECG parameters will be summarized, and counts and percentages of abnormal 
findings will be presented. Changes from parent study baseline (for patients rolling over from 
Study TV50717-CNS-30046 or Study TV50717-CNS-30060) or from day 1 (for patient[s] rolling 
over from Study SD-809-C-17) in ECG parameters will be summarized descriptively. In addition, 
the number and percentage of patients with on-treatment QTcF values >450, >480, or >500 msec 
and change from baseline (Study TV50717-CNS-30046 or Study TV50717-CNS-30060) or day 1
(Study SD-809-C-17) >30 or >60 msec will be presented.
The use of concomitant medications will be summarized by therapeutic class using descriptive 
statistics. Concomitant medications will include all medications taken while the patient is treated 
with IMP.
Observed values in the Children’s C-SSRS and observed values and changes from day 1 in the 
CDI-2 (Parent and Self-Report Profiles) will be presented for all patients.

BACKGROUND INFORMATION
1.1.
Introduction
Tourette syndrome (TS) is a neurodevelopmental disorder characterized by multiple motor and 
phonic tics and a variety of behavioral and psychiatric comorbidities (Jankovic 2001, Jankovic 
and Kurlan 2011). Studies have suggested that up to 7% of school children fulfill the diagnostic 
criteria for TS (Kurlan et al 2002). Tics are classified as either simple or complex; simple motor 
tics include eye blinks, shoulder shrugs, while simple vocal tics include grunting, coughing, and 
sniffing. Complex motor tics include touching/tapping and walking in patterns, while complex 
vocal tics include echolalia (repeating another’s speech) and coprolalia (shouting obscenities or 
profanities) (Jankovic 2001, Shaw and Coffey 2014). TS was thought to be a psychogenic 
disorder until improvement with neuroleptics was first observed in the 1960s, leading to the 
theory of central dopaminergic hyperactivity as a possible mechanism of tics associated with TS. 
When the symptoms impair function, most physicians utilize alpha adrenergic drugs (guanfacine, 
clonidine), typical neuroleptics (haloperidol, pimozide, fluphenazine), or atypical neuroleptics 
(olanzapine, ziprasidone, aripiprazole) to control tics (Gilbert and Jankovic 2014, Wijemanne et 
al 2014). In the United States of America (USA), haloperidol and pimozide are approved for the 
treatment of tics associated with TS, while aripiprazole carries a broader indication of “for the 
treatment of TS”. Neuroleptics have the potential for serious adverse effects, including tardive 
dyskinesia (TD), which typically manifests as an irreversible orofacial stereotypy, and other 
forms of hyperkinetic movement disorder (Waln and Jankovic 2013). Up to 25% of adults 
chronically treated with dopamine receptor antagonists (neuroleptics; including the so-called 
“atypical” neuroleptics, such as aripiprazole) eventually develop TD (Jankovic 1995, Pasricha et 
al 2006, Peña et al 2011). Although elderly individuals, especially women, are particularly 
susceptible to developing TD, this iatrogenic condition may also rarely occur in children (Mejia 
and Jankovic 2010). Tetrabenazine, which depletes dopamine presynaptically, has been shown to 
be effective in treating the tics associated with TS (Jain et al 2006, Jankovic 2015, Jankovic and 
Beach 1997, Kenney et al 2007, Paleacu et al 2004, Porta et al 2008) but has not been 
documented to cause TD in clinical use.
While generally effective in reducing the tics of TS, tetrabenazine is associated with frequent 
adverse events, including somnolence, nausea, depression, insomnia, and parkinsonism, that may 
limit its utility. Moreover, tetrabenazine is an immediate-release formulation with the following 
limitations: (1) adverse events of tetrabenazine, such as somnolence, akathisia, and anxiety, are 
often associated with peak concentration after dosing; (2) the active metabolites have short 
half-lives, with the attendant requirement to dose the immediate-release formulation frequently; 
and (3) the active metabolites alpha-dihydrotetrabenazine (α-HTBZ) and 
beta-dihydrotetrabenazine (β-HTBZ) are either primarily (α) or exclusively (β) metabolized by 
cytochrome P450 2D6 (CYP2D6). Polymorphisms in the CYP2D6 gene necessitate genotyping 
to prevent poor metabolizers from experiencing significantly greater exposure to the active drug 
moiety than extensive metabolizers (Mehanna et al 2013).
To address the limitations of commercial tetrabenazine (Xenazine®), Auspex, a wholly owned 
subsidiary of Teva Pharmaceutical Products R&D, Inc, has developed a deuterated tetrabenazine 
(referred to as TEV-50717, previously SD-809) that is eliminated more slowly than 

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
38
tetrabenazine. TEV-50717 has been shown to reduce plasma fluctuation and dosing frequency 
and thus has the potential to improve overall tolerability as compared to that of tetrabenazine. 
Data in patients receiving TEV-50717 for the treatment of chorea associated with Huntington’s
disease (HD) demonstrate a favorable safety profile with low rates of neuropsychiatric adverse 
events. In TS patients with troublesome motor and phonic tics, preliminary efficacy and safety 
data for TEV-50717 have been generated in an open-label, Phase 1b pilot study (SD-809-C-17). 
Results of this study are summarized in Section 1.3.2.2 and support further development of 
TEV-50717 for treatment of tics associated with TS.
TEV-50717 was granted breakthrough status for treatment of TD by the Food and Drug 
Administration (FDA) based on the results of Study SD-809-C-18, and NDA 209885 was 
granted priority review status. TEV-50717 was approved for the treatment of chorea associated 
with HD on 03 April 2017.
1.2.
Name and Description of Investigational Medicinal Product
TEV-50717 (deutetrabenazine) is a vesicular monoamine transporter 2 (VMAT2) inhibitor with 
the chemical name (RR, SS)-1,3,4,6,7,11b-hexahydro-9,10-di(methoxy-d3)-3-(2-methylpropyl)-
2H-benzo[a]quinolizin-2-one. During the open-label period, TEV-50717 tablets are available in 
the following dose strengths: 6, 9, and 12 mg. Each dose strength will have a marking of SD 6, 
SD 9, and SD 12 corresponding to the dose strength and a distinct color: 6 mg – purple, 9 mg –
blue, and 12 mg – beige. The investigational medicinal product (IMP) will be supplied in 20- or 
60-count tablets per dose strength per bottle.
A more detailed description of the product is given in Section 3.8
During the randomized drug withdrawal and re-titration period, TEV-50717 tablets are available 
in the following dose strengths: 6, 9, 12, 15, and 18 mg, all of which are identical in size, shape, 
and color (white). The IMP will be supplied in 20-count bottles.

Findings from Nonclinical and Clinical Studies
Brief summaries of nonclinical pharmacology, pharmacokinetics, and toxicology studies and 
clinical studies are provided in the following sections. More detailed information is provided in 
the current Investigator’s Brochure (IB), including the IB supplement for TS (if available).
1.3.1.
Nonclinical Studies
The key nonclinical study findings are provided below, with details available in the IB.
1.3.1.1.
Nonclinical Pharmacology
TEV-50717 is a selectively deuterium-substituted VMAT2 inhibitor structurally related to 
tetrabenazine. The metabolites formed from TEV-50717 (α-HTBZ and β-HTBZ) are potent 
inhibitors of VMAT2 binding, with Ki values of 3.8 and 22 nM, respectively, that are similar to 
previously reported values of their corresponding nondeuterated forms (Scherman et al 1988). 
Off-target binding occurs to a similar extent with deuterated and nondeuterated α-HTBZ and 
β-HTBZ. TEV-50717 and tetrabenazine in male rats at doses resulting in similar systemic 
exposure to the test articles (α-HTBZ and β-HTBZ) produced similar, expected, exaggerated 
central nervous system pharmacological effects. In particular, the adverse event of catalepsy, a 

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
39
known response in rats to drugs that reduce central nervous system dopamine concentrations 
(Fuenmayor and Vogt 1979), was similar in magnitude after TEV-50717 and tetrabenazine 
administration. 
1.3.1.2.
Nonclinical Pharmacokinetics and Drug Metabolism
In human liver S9, the metabolite profile of TEV-50717 overlapped with that of tetrabenazine. In 
a clinical comparative human [14C]-absorption, distribution, metabolism, excretion, and 
mass-balance study, the approximately 22 metabolites of TEV-50717 were also metabolites of 
tetrabenazine. Thus, previous clinical experience with tetrabenazine provides predictive 
information about the safety of TEV-50717 and its metabolites. 
Tetrabenazine, α-HTBZ, and β-HTBZ, and by extension, their deuterated forms, do not inhibit or 
induce cytochrome P450 (CYP) isoenzymes at clinically relevant concentrations (Xenazine 
Prescribing Information 2015). M1, a minor metabolite that may circulate in greater 
concentrations as a metabolite of TEV-50717 as compared to tetrabenazine, is neither an 
inhibitor of major CYP isoenzymes or transporters nor an inducer of CYP isoenzymes.
1.3.1.3.
Toxicology
General and Reproductive Adult Toxicology: Oral administration of TEV-50717 in rats reduced
body weight gain, increased mammary hyperplasia, and produced estrus cycle changes, all of 
which occurred with tetrabenazine at doses that produced similar systemic exposures to test 
articles and metabolites. Mammary and estrus effects are likely consequences of reduced central 
dopamine and subsequently increased prolactin, consistent with information in the Xenazine®
(tetrabenazine) label. Oral administration of TEV-50717 in pregnant rats did not produce test 
article-related embryofetal toxicities, even at doses that led to reduced body weight gain in dams. 
Oral administration of metabolite M1 to pregnant rats from gestational days 6 to 17 produced no 
test article-related maternal or fetal toxicities.
Genetic Toxicology: TEV-50717 and its α-HTBZ and β-HTBZ metabolites were negative in 
in vitro studies for mutagenicity (bacterial reverse mutation, or the Ames test) and for 
chromosomal structural aberrations in human peripheral blood lymphocytes. Oral doses of 
TEV-50717 were negative for inducing micronuclei in the bone marrow of treated mice. 
Juvenile Toxicology: The effects of TEV-50717 on juvenile development was assessed in male 
and female rats with oral dosing from weaning (postnatal day [PND] 21) to PND 71, similar to 
human dosing from Year 2 through early adolescence and overlapping with TEV-50717 oral 
dosing in a general adult toxicology study. The effects of M1 were assessed in male and female 
juvenile rats from PND 25 to PND 70 with a recovery phase and postdosing reproductive 
assessment.
TEV-50717 produced no test-article-related effects on learning and memory functions, on 
histopathology assessments, on reproductive capacity (male and female fertility, estrus cyclicity),
or on intrauterine survival of embryos from matings during recovery from test article 
administration. Adversely reduced body weight gain and adverse clinical observation of tremors 
and in-cage hyperactivity were all noted in previous studies with adult rats; these effects have not 
predicted adult clinical intolerance to TEV-50717. The highest dose level of M1 (50 mg/kg/day) 
produced no test article-related toxicities (clinical observations, changes in body weight gain, 

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
40
clinical pathology, histopathology, ophthalmology, and performance in learning and memory 
tests).
The no-observed-adverse-effect level (NOAEL) for toxicities in juvenile rats is lower than that in 
adults; however, the total (α+β)-HTBZ exposure multiples or safety margins comparing rat to 
humans at the adult and juvenile age categories are similar. The potential for increased 
sensitivity to the effects of TEV-50717 in pediatric patients is mitigated by 2 factors. First, the 
effects of TEV-50717 on behavior and weight gain recovered with cessation of test article 
administration in the juvenile rat toxicology study. Second, the clinical significance of tremors 
and reduced body weight gain in rats dosed with TEV-50717 are unclear because these findings 
were not adverse events of note in adults or adolescent patients. While hypoactivity in rats has 
the potential to relate to clinical observations of somnolence, this adverse effect is controlled 
with dose reduction. In clinical comparison, the adverse event profile of tetrabenazine in adult 
patients is qualitatively similar to patients from approximately 22 months to 18 years of age (Jain 
et al 2006, Kenney et al 2007, Porta et al 2008).

1.3.2.1.
Clinical Pharmacology Studies
Seven Phase 1 clinical pharmacology studies were conducted in healthy adult volunteers. In 
addition, sparse pharmacokinetic sampling was included in the Phase 3 studies with HD 
patients where population pharmacokinetic analyses were performed to extensively evaluate 
the pharmacokinetics and pharmacokinetics/pharmacodynamics relationship of TEV-50717. A 
summary of the clinical pharmacology findings is provided in the IB.
Pharmacometric analyses of TEV-50717’s active metabolites based on the Phase 1 clinical 
pharmacology in healthy adult volunteers were performed to support dose selection and 
pharmacokinetic characterization in a pediatric population. Subsequently, a further 
pharmacometric analysis of TEV-50717’s active metabolites following administration of 
TEV-50717 to adolescent TS patients with tics (Study SD-809-C-17) was recently completed. 
The results of these analyses are described in Section 1.3.2.3.

Clinical Safety and Efficacy Studies
TEV-50717 has pharmacologic activity indistinguishable from tetrabenazine, a VMAT2 inhibitor 
with established efficacy in treating the motor and phonic tics associated with TS. Preliminary 
efficacy of TEV-50717 has been evaluated in an open-label, Phase 1b pilot study in patients with 
troublesome motor and phonic tics associated with TS (Study SD-809-C-17). Twenty-three 
patients were enrolled in this study across 9 centers in the USA. Patients who completed the 
study received treatment with TEV-50717 for a total of 8 weeks and had a safety follow-up 
assessment 4 weeks after treatment. The following efficacy observations were made in this 
study:

TEV-50717 was effective in reducing both motor and vocal tics from baseline to 
week 8 (end of treatment), demonstrating a 37.60% reduction in the Yale Global Tic 
Severity Scale (YGTSS) Total Tic Score (TTS) from baseline (p<0.0001).

The reduction in tic severity was associated with significant improvement (from 
baseline to week 8) in the YGTSS Impairment score (-35.32%; p<0.0001), the 
Tourette Syndrome-Clinical Global Impression (TS-CGI) score (-1.2 points; 
p<0.0001), and in the Patient Global Impression of Change score. For example, 
compared to baseline, 76% of patients completing the study reported that they were 
“much” or “very much” improved at week 8.

Between week 8 (end of treatment) and week 9 (1 week post-treatment), an increase 
in YGTSS and TS-CGI scores were observed following discontinuation of treatment 
with TEV-50717 at week 8, indicating a re-emergence of symptoms, thus providing 
further evidence of efficacy.
The safety profile of TEV-50717 has been characterized to date in healthy volunteers as well as 
in patients with chorea associated with HD and TD (as detailed in the IB). Study SD-809-C-17
also evaluated the safety of TEV-50717 in patients with TS. Results of the safety analyses 
indicate that treatment with TEV-50717 at dosages up to 36 mg daily given in 2 divided doses is 
generally safe and well tolerated for up to 8 weeks in patients with TS. No serious treatment-
emergent adverse events (TEAEs) or severe TEAEs occurred in this study. The most frequently 
observed TEAEs during the entire treatment period were fatigue and headache, each reported in 
4/23 (17.4%) patients, followed by irritability which was reported in 3/23 (13.0%) patients. 
There were no clinically meaningful trends in mean changes from baseline for any clinical 
laboratory variable or any other observations related to safety.
1.3.2.3.
Pharmacometrics Analysis of TEV-50717 Active Metabolites to Support Dose 
Selection and Pharmacokinetic Characterization in a Pediatric Population
Population pharmacokinetics modeling of the TEV-50717 active metabolites -HTBZ and 
β-HTBZ has been performed throughout the clinical development program. Based on sequential 
pharmacokinetics sampling data obtained in healthy volunteers in the Phase 1 program, a 
structural population pharmacokinetics model was developed to guide dose selection for HD 
patients with chorea (Study SD-809-CLN-076) and subsequently optimized to better describe the 
absorption/bioconversion profile of -HTBZ and β-HTBZ (Study SD-809-CLN-077). 

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
42
Employing the structural model defined in Study SD-809-CLN-077, sequential and sparse 
pharmacokinetics sampling data obtained from Study SD-809-C-17 were combined with the 
Phase 1 data employed in Study SD-809-CLN-077 to estimate the exposure total of (+β)-HTBZ 
in adolescent patients (age 12 to 18 years) with TS and to simulate exposure in adolescent and 
pediatric patients (age 6 to 11 years) with and without concomitant use of a strong CYP2D6 
inhibitor across a range of doses (Appendix B). Population model parameters were re-estimated 
for the combined Phase 1 and adolescent data obtained from patients in Study SD-809-C-17. The 
model was used to simulate total (+β)-HTBZ exposures across a range of body weights 
corresponding to a pediatric and adolescent population according to the Centers for Disease 
Control growth charts. 
This analysis indicated that exposure to total (+β)-HTBZ is influenced by body weight, and a 
reduction in dose for pediatric and adolescent patients weighing <40 kg is necessary in order to 
provide comparable exposure to doses up to 48 mg per day in adults, a level previously 
demonstrated to be safe and well tolerated in treated patients with chorea associated with HD. 
This analysis provides the basis for the dosing recommendations in Section 5.1.

Selection of Investigational Medicinal Product and Doses
A detailed description of IMP administration is presented in Section 5.1.
1.5.1.
Justification for Dose of Active Drug
The dose ranges to be evaluated in this study, based on body weight and CYP2D6 impairment 
status on day 1, were selected on the basis of the safety, preliminary efficacy, and population 
pharmacokinetics data generated from Study SD-809-C-17 (Table 2). In Study SD-809-C-17, 
TEV-50717 up to 18 mg twice daily (bid [36 mg/day]) was well tolerated and demonstrated a 
clinically meaningful benefit in adolescents with TS-associated tics. The dosages proposed in the 
present study aim to match the exposure achieved in adults receiving up to 48 mg/day (24 mg 
bid), a level previously demonstrated to be efficacious, safe, and well tolerated in patients with 
HD-associated chorea. 
Similar to one of the parent studies (TV50717-CNS-30046), IMP will be titrated based on 
investigator, patient, and parent/guardian assessments of tic reduction and adverse events. This 
dosing strategy is practical in a clinical study setting and affords sufficient time between dose 
steps for safety and efficacy to be assessed. It is also consistent with the clinical application of 
tetrabenazine, another VMAT2 inhibitor with accepted efficacy in this population. 
1.6.
Compliance Statement
This study will be conducted in full accordance with the International Conference on 
Harmonisation (ICH) Harmonised Tripartite Guideline for Good Clinical Practice (GCP) E6 and

STUDY DESIGN
3.1.
General Design and Study Schematic Diagram
This is a 56-week, open-label, single-arm study that includes a 2-week, double-blind, 
placebo-controlled, randomized drug withdrawal period followed by a 3-week blinded 
re-titration period to evaluate the safety of TEV-50717 in children and adolescents with tics 
associated with TS after they have successfully completed any of the parent studies (SD-809-C-
17 [Phase 1b], TV50717-CNS-30046 [Phase 2/3], or TV50717-CNS-30060 [Phase 3]). Patients 
rolling over from Study SD-809-C-17 will need to undergo all day 1 assessments. For patients 
rolling over from Study TV50717-CNS-30046 or Study TV50717-CNS-30060, the week 13 visit 
(Study TV50717-CNS-30046) or the week 9 visit (Study TV50717-CNS-30060) will be the day 
1 visit for Study TV50717-CNS-30047. If the patient does not wish to enroll in Study TV50717-
CNS-30047 at that visit, they can enroll up to 1 week following the week 13 or week 9 visits, 
respectively.
For patients rolling over from Study SD-809-C-17, this study will consist of a 4-week screening 
period (up to 31 days) and up to 54 weeks of treatment. All participating patients are expected to 
participate in this study for its entire duration, which is a minimum of 56 weeks. Patients will 
have a follow-up telephone contact to evaluate safety 1 week after the end of the washout period 
(2 weeks after their last dose of IMP). The end of study is defined as the date of the week 56 visit 
of the last participant.
Informed consent/assent, depending on the child’s age, as appropriate, will be obtained before 
any study procedures are performed. For patients rolling over from Study TV50717-CNS-30046 
or Study TV50717-CNS-30060, informed consent/assent, as appropriate, may be obtained prior 
to the day 1 visit, up to 4 weeks in advance of open-label study participation. Any patient that 
turns 18 years of age during the course of Study TV50717-CNS-30047 will need to be 
re-consented as an adult.
Patients who have successfully completed any of the parent studies may be eligible to enroll in 
the current study after they complete a 1-week washout period and the final evaluation (week 13 
in Study TV50717-CNS-30046 or week 9 in Study TV50717-CNS-30060) in the parent study. 
To reduce patient burden, after obtaining informed consent/assent, depending on the child’s age, 
as appropriate, some data collected in Study TV50717-CNS-30046 or Study TV50717-
CNS-30060 will be used to provide corresponding day 1 data in the current open-label study (see 
Table 1). 
All screening procedures will be performed for patients rolling over from Study SD-809-C-17, as 
they will have been off IMP for several months at the time of enrollment into the current study. 
Site-administered scales include the YGTSS, 
, Mini International Neuropsychiatric 
Interview for Children and Adolescents (MINI Kid, version 6.0), and the C-SSRS and 
self-administered scales include the TS-PGII, 
, CDI-2, and C&A-
GTS-QOL. For the YGTSS, input from the caregiver/adult is required. For 
 the TS-PGII 
 
, input from the caregiver/adult is permitted. For all other scales, children 13 years of 
age and under, interviews may be performed separately or jointly with the caregiver/adult as 
appropriate or as defined by the scale. For children over 13 years of age, caregiver/adult

48
involvement is strongly encouraged. Questions should be directed to the child, but the 
caregiver/adult should be encouraged to add relevant information.
The assessments and procedures performed during each study visit are detailed in Table 1 and 
Section 3.13.
Up to approximately 227 patients are planned to be enrolled (approximately 1 patient is
estimated to enroll from the Phase 1b Study SD-809-C-17, up to approximately 99 patients are 
estimated to enroll from the Phase 2/3 Study TV50717-CNS-30046, and up to approximately 
127 patients are estimated to enroll from the Phase 3 Study TV50717-CNS-30060).
When approximately 100 patients have completed the 28-week clinic visit, an interim analysis, 
including data from day 1 and up to week 28 visit only, will be conducted to provide descriptive, 
long-term safety and efficacy data to be used in regulatory submissions. To maintain data 
integrity of Study TV50717-CNS-30047, only a limited number of personnel who do not have 
contact with the sites will have access to this interim data in preparation for the regulatory filing. 
As no decisions regarding conduct of the study will be made based on the descriptive interim 
analysis, no alpha will be spent.
Patients who complete all scheduled visits will have procedures and assessments performed at 
the final visit (week 54). Patients who withdraw from the study before completing the week 54
evaluation period will have the week 54 procedures and assessments performed at their final 
visit, and a follow-up telephone contact for safety evaluation 2 weeks after their last dose of 
IMP. 
The study schematic diagram is presented in Figure 1. An additional diagram that details the 
blinded, randomized drug withdrawal/titration post-drug withdrawal period (Part B of the study) 
is presented in Figure 2.

a Maximum total daily dose for patients ≥40 kg is 48 mg/day (24 mg bid), 30 to <40 kg is 42 mg/day (21 mg bid), 
and 20 to <30 kg is 30 mg/day (15 mg bid). For those considered CYP2D6 impaired, maximum daily dose for 
patients ≥40 kg is 36 mg/day, 30 to <40 kg is 24 mg/day, and 20 to <30 kg is 18 mg/day (Table 2).
b If a stable dose is reached before the indicated time, the patient should continue taking that dose for the remainder 
of the titration period and throughout the maintenance therapy dosing.

3.1.1.
Screening Period (up to 31 days)
For patients from Study SD-809-C-17:
Screening period (up to 31 days): All screening procedures will be performed for patients rolling 
over from Study SD-809-C-17, as they will have been off IMP for several months at the time of 
enrollment into this study (TV50717-CNS-30047). 
After informed consent/assent, depending on the child’s age, as appropriate, is obtained, patients 
who are stable from a medical and psychiatric standpoint will undergo a screening evaluation, 
including medical history, physical and neurological examination, assessment of vital signs, 
laboratory testing, and 12-lead ECG, along with rating scales to assess comorbid TS symptoms 
and behavioral status. 

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04

50
At the discretion of the investigator, the screening visit may be divided into 2 visits if the visit 
length is deemed to be too burdensome for the patient. Patients may be rescreened 1 time if there 
is a change in the patient’s medical background, a modification of study entry criteria, or other 
relevant change. (Note: Details of a patient’s rescreening must be approved and documented by 
the medical monitor and/or Clinical Surveillance and Training [CST] team.)
For patients from Study TV50717-CNS-30046 or Study TV50717-CNS-30060:
The screening evaluation for this open label study occurs at the end of the treatment period in the 
double-blind study. To reduce patient burden and not collect duplicate information, after 
obtaining informed consent/assent, depending on the child’s age, as appropriate, relevant data 
collected in Study TV50717-CNS-30046 or Study TV50717-CNS-30060 will be used to provide 
corresponding data in this open-label study (see Table 1).
Part A:
3.1.2.
Day 1 Visit (All Patients)
For patients rolling over from Study TV50717-CNS-30046 or Study TV50717-CNS-30060, the 
week 13 visit (Study TV50717-CNS-30046) or the week 9 visit (Study TV50717-CNS-30060) 
will be the day 1 visit for Study TV50717-CNS-30047. Patients rolling over from 
Study SD-809-C-17 will need to undergo all day 1 assessments. Day 1 assessments for 
Study TV50717-CNS-30047 that are identical to Study TV50717-CNS-30046 week 13 or 
Study TV50717-CNS-30060 week 9 assessments do not need to be repeated. Additionally, 
Study TV50717-CNS-30047 required evaluations will be completed at Study TV50717-
CNS-30046 week 13 visit or Study TV50717-CNS-30060 week 9 visit (see Table 1). For all 
patients, the day 1 visit will occur on or as close as possible to the week 13 or week 9 visit from 
Study TV50717-CNS-30046 and Study TV50717-CNS-30060, respectively, but not >7 days 
beyond those respective visits.
For patients with clinically significant laboratory abnormalities at week 12 in Study TV50717-
CNS-30046 or at week 8 in Study TV50717-CNS-30060, Study TV50717-CNS-30046 week 13 
value(s) or Study TV50717-CNS-30060 week 9 value(s) will serve as day 1 laboratory values in 
this study. Rollover for such patients must be approved and documented by the medical monitor 
and may be delayed.
3.1.3.
Titration Period (7 Weeks)
As patients from Study SD-809-C-17 will have been off IMP for several months at the time of 
enrollment, and since patients from Study TV50717-CNS-30046 or Study TV50717-CNS-30060 
will have discontinued IMP (TEV-50717 or placebo) for at least 1 week at completion of the 
parent study, all patients will undergo TEV-50717 dose titration in this study. Patients will 
receive 6 mg of TEV-50717 with food on the evening of day 1. Tablets should be taken with 
food (eg, a snack) and should not be taken on an empty stomach. The titration scheme and 
maximum dose will be determined by body weight and CYP2D6 impairment status from the 
parent study. Patients will be classified as CYP2D6 impaired if they are receiving a strong 
CYP2D6 inhibitor or are a CYP2D6 poor metabolizer based on blinded assessment of CYP2D6 
genotype at baseline of the parent study. Patients who are CYP2D6 impaired will have a dose 
cap in the open-label study, as shown in Table 2. Patients and their caregiver/adult will interact 
weekly with the clinical research staff, either by telephone contact or in-clinic visits from week 1 

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
51
through week 7 of the titration period, in order to evaluate safety and establish a dose of 
TEV-50717 that optimally reduces tics and is well tolerated (optimal dose). Safety evaluations 
during the titration period include assessment of vital signs, monitoring for adverse events and 
concomitant medications, 12-lead ECGs, and rating scales for depression and suicidality.
In-person (in-clinic) study visits will be scheduled at weeks 2, 4, and 6, and telephone contacts 
will be scheduled for weeks 1, 3, 5, and 7 in order to assess adverse events and tic severity. 
The dose of the IMP should be increased on a weekly basis until one of the following occurs:

The investigator determines that there has been a clinically meaningful reduction in 
tics.

The patient experiences a protocol-defined “clinically significant” adverse event
(defined as an adverse event that is related to IMP and is either moderate or severe in 
intensity or meets the criteria for a serious adverse event).

The maximum allowable dose is reached, based on the patient’s weight and use of 
strong CYP2D6 impairment status.
If a stable dose is reached before the week 7 telephone call, the patient should continue on that 
dose (ie, the dose should not be increased further) for the remainder of the titration period. If a 
patient experiences depression, suicidal ideation or behavior, anxiety, akathisia, parkinsonism, 
somnolence, any other adverse event that interferes with daily activity, or adverse event that is 
related to IMP, the investigator will determine if a dose reduction or suspension is necessary. If 
the determination is made during a telephone contact that a patient requires a dose reduction or 
suspension, an unscheduled in-clinic visit should be conducted as soon as practicable thereafter.
Dose adjustments should be made based on all available information, including the patient and 
caregiver/adult reports of adverse events and tic reduction, the clinical assessment of safety and 
efficacy by the investigator, and the information from rating scales.
3.1.4.
Maintenance Period
At the end of the titration period, the patient’s initial dose for the maintenance period will be 
established. Dose adjustments of TEV-50717 (upward or downward) may be made during the 
maintenance period, if necessary, but not more often than every 5 days and only in increments of 
6 mg. As during titration, dose adjustments should be made based on all available information.
After dose adjustment, if the maintenance dose for a patient is 6 mg, the dose should be taken 
once a day in the morning with food (other dose levels are taken twice daily).
During the maintenance period, in-person (in-clinic) study visits will be scheduled at weeks 8, 
15, 34, 41, and 54 for assessments of safety and efficacy and telephone contacts will be 
scheduled for weeks 21 and 47 in order to assess adverse events and tic severity. The randomized 
drug withdrawal and re-titration period (Part B) will occur from the end of week 28 through the 
end of week 33, and then the Part A maintenance period will resume, along with the ability to 
make dose adjustments as described above. At week 54, patients will undergo a complete 
evaluation, including physical and neurological examination, safety laboratory testing, 12-lead 
ECG, CDI-2, and C-SSRS assessments, as well as the YGTSS, TS-CGI, 
 TS-PGII, 
, and C&A-GTS-QOL.

3.1.5.
Washout Period and Follow-up
All patients will discontinue IMP at the week 54 visit and will return 1 week later (week 55) for 
evaluation of safety and tic reduction. Patients will have a follow-up telephone contact for safety 
evaluation 1 week after the end of the washout period (2 weeks after their last dose of IMP)
(week 56).
See Table 1 for study procedures and assessments.
See Figure 1 and Figure 2 for study schema.
Part B:
3.1.6.
Blinded, Randomized Drug Withdrawal Period and Titration Post-Drug 
Withdrawal Period (5 Weeks)
At the week 28 visit, the patients will be randomized 2:1 to their current dose of TEV-50717 or
placebo in order to check for return of symptoms. Because IMP is dispensed as enough doses for 
2 weeks (current dose level and next dose level), the week 28 visit (Day 196) is considered the 
first day of the randomized withdrawal period, although the patient will begin taking blinded 
IMP on Day 197. Patients will have a follow-up telephone contact for safety evaluation 1 week 
after the start of the randomized drug withdrawal period. At week 30, safety and efficacy will be 
assessed. At the week 30 visit, patients who receive TEV-50717 during the randomized drug 
withdrawal period will continue at the same dose in a blinded manner from the start of week 31 
to the start of week 34. Any patient who was randomized to placebo during this 2-week period
will undergo blinded re-titration. Patients will have a follow-up telephone contact for safety 
evaluation at weeks 31 and 33.
Titration Post-Drug Withdrawal (Weeks 31, 32, and 33)
Any patient who was randomized to placebo between the week 28 and week 30 visits will 
undergo re-titration to their previously established maintenance dose over the 3 weeks of 
treatment following the randomized drug withdrawal period (start of week 31 to the start of week 
34 [Days 211 through 232]). The titration scheme and maximum dose will be determined based 
on the previously established maintenance dose according to Table 3. The dose of IMP for each 
patient who underwent 2 weeks of placebo will be titrated back to the maintenance dose that was 
used by the patient up to week 28 followed by continued maintenance therapy at that dose.
All patients should be back at their maintenance dose on or before the start of week 34 and return 
to open-label treatment for the remainder of the study (note that, because IMP is dispensed for 
2-week periods, patients will use blinded bottles through the end of week 34; however, all 
patients will be known to be on active treatment at the start of week 34).
3.2.
Justification for Study Design and Placebo-Controlled Randomized 
Drug Withdrawal
At the present time, effective treatment options for TS are suboptimal and limited. As a chronic 
condition impairing major life activities during childhood, such as occupational, social, and 
educational activities, TS presents an area of significant unmet medical need in the pediatric 
population.

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
53
Preliminary efficacy and safety data for TEV-50717 as a treatment for TS have been generated in 
an open-label, Phase 1b pilot study (SD-809-C-17) in patients. Results of Study SD-809-C-17
support further development of TEV-50717 as a treatment of TS.
Two parent studies, TV50717-CNS-30046 and TV50717-CNS-30060, are underway. They are 
randomized, double-blind, placebo-controlled studies of the efficacy and safety of TEV-50717 
on the tics in patients with TS. This is an open-label, single-arm study that includes a 2-week, 
double-blind, placebo-controlled, randomized drug withdrawal period in which patients with TS 
may be eligible to participate after successful completion of any of the parent studies (SD-809-C-
17 [Phase 1b], TV50717-CNS-30046 [Phase 2/3], or TV50717-CNS-30060 [Phase 3]). Patients 
who have successfully completed a parent study may be eligible to enroll in this study after they 
complete a 1-week washout period and the final evaluation in the parent study. For patients 
rolling over from Study TV50717-CNS-30046 or Study TV50717-CNS-30060, the week 13 visit 
(Study TV50717-CNS-30046) or the week 9 visit (Study TV50717-CNS-30060) will be the 
day 1 visit for Study TV50717-CNS-30047. If the patient does not wish to enroll in 
Study TV50717-CNS-30047 at that visit, they can enroll up to 1 week following the week 13 or 
week 9 visits, respectively. The end of study is defined as the date of the week 56 visit of the last 
participant.
Inclusion and exclusion criteria have been designed to minimize the risk to patients while 
maintaining a consistent level of TS symptoms to allow detection and analysis of a drug effect. 
Exclusion criteria were designed to exclude patients with concomitant conditions that may 
increase their risk to drug treatment.
The open-label study design (ie, no placebo or comparator) was selected to allow further 
evaluation and review long-term safety of TEV-50717 in this patient population. Patients will 
receive twice daily dosing for up to 54 weeks (those on the 6-mg dose will receive once-daily 
dosing), with an initial 7-week titration period to allow for optimal dose selection. At the 
week 28 visit, patients will begin a 2-week blinded, randomized drug withdrawal period. The 
randomized drug withdrawal period will rigorously assess the long-term maintenance of effect. 
Patients will be randomized to their current dose of TEV-50717 or placebo for 2 weeks. After 
completing the 2 weeks, patients will continue their same dose of TEV-50717 in a blinded 
manner or will be re-titrated (patients receiving placebo only) in a blinded manner for 3 weeks. 
At week 34, all patients will resume their maintenance dose. This is a classic ABA study design
(ie, drug, placebo, drug) that allows for a more rigorous test of the intervention. In the traditional 
AB design, changes in symptoms (particularly in a long trial) could be attributed to other factors 
(eg, life changes, societal issues, and regression to the mean); however, an acute change 
demonstrated only in a placebo group among subjects that have been maintained for several 
months would reduce the likelihood of any other explanations for changes in symptoms.

Randomization and Blinding
This is an open-label study that includes a 2-week, double-blind, placebo-controlled, randomized 
drug withdrawal period followed by a 3-week blinded re-titration period. At the start of the 
randomized drug withdrawal period (end of week 28), the patients will be randomized 2:1 to the 

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
56
current dose or placebo in order to check for return of symptoms. During the entire 5-week 
period, patients randomized to TEV-50717 will stay on their established maintenance dose of 
blinded active IMP. Patients who receive placebo during the randomized drug withdrawal period 
will undergo blinded re-titration post-drug withdrawal. All patients will return to open-label 
dosing at week 34 (note that, because IMP is dispensed for 2-week periods, patients will use 
blinded bottles through the end of week 34; however, all patients will be known to be on active 
treatment at the start of week 34).
During the blinded drug withdrawal and re-titration period, patients and investigators will remain 
blinded to treatment assignment. In addition, the sponsor’s and development partner’s clinical 
personnel and all vendors (with the exception of the Interactive Response Technology [IRT]
vendor and the IMP packaging vendor) involved in the study will be blinded to the IMP identity 
until the database has been locked for analysis and the treatment assignments are revealed.
Patients will be centrally randomly assigned to the treatment groups by means of a 
computer-generated randomization list. The creation of the randomization list will be under the 
responsibility and oversight of Syneos Health.
The randomized treatment and medication allocation will be assigned to the relevant treatment 
groups through a qualified service provider (ie, via IRT). The management of the IRT system 
will be done by a qualified service provider under the oversight of Nuvelution TS Pharma, Inc.
(referred to hereafter as Nuvelution TS Pharma).
The staff member at the investigational center who will dispense the IMP will not know the 
treatment given to each patient during the blinded drug withdrawal and re-titration period.
3.6.
Maintenance of Randomization and Blinding
3.6.1.
Maintenance of Randomization
Patient randomization codes will be maintained in a secure location within Syneos Health. At the 
time of analysis, when treatment codes are needed, the Syneos Health statistician assigned to the 
study will make a request to unblind and will receive the unblinded codes and unblinded IMP 
assignment according to the processes defined in the relevant Standard Operating Procedure 
(SOP).
3.6.2.
Blinding and Unblinding
In case of a serious adverse event, pregnancy, or in cases when knowledge of the IMP 
assignment is needed to make treatment decisions, the investigator may unblind the patient’s 
IMP assignment as deemed necessary, mainly in emergency situations. The patient’s randomized 
treatment will be made available to the investigator(s) via the IRT system. If possible, the 
medical monitor should be notified of the event before breaking of the code. If this is not 
possible, the medical monitor should be notified immediately afterward, and the patient’s 
randomized treatment should not be communicated to the medical monitor. Breaking of the 
randomization code can always be performed by the investigational center without prior approval 
by the medical monitor.
When a blind is broken, the patient will be withdrawn from the study, and the event will be 
recorded on the case report form (CRF). However, if a patient is unblinded by mistake, the 

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
57
investigator should discuss with the medical monitor whether or not the patient should be 
withdrawn. The circumstances leading to the breaking of the code should be fully documented in 
the investigator’s study files and in the patient’s source documentation. Assignment of IMP 
should not be recorded in any study documents or source document.
In studies with blinding, for an adverse event defined as a suspected unexpected serious adverse 
reaction (SUSAR) (ie, reasonable possibility; see Section 7.1.4), Global Patient Safety and 
Pharmacovigilance may independently request that the blind code be broken (on a case-by-case 
basis) to comply with regulatory requirements. The report will be provided in an unblinded 
manner for regulatory submission. If this occurs, blinding will be maintained for the investigator 
and for other personnel involved in the conduct of the study and analysis and reporting of the 
data.
3.7.
Independent Data Monitoring Committee
An IDMC will review accumulating safety data on a regular basis to ensure the continuing safety 
of the study patients and to review any study conduct issues.
The IDMC will be composed of independent physicians with expertise in the relevant therapeutic 
field and other relevant experts, such as a statistician. The IDMC will receive safety data 
periodically, which will be presented by masked treatment groups. They will have the right to 
recommend modification of the study for safety reasons. 
IDMC sessions can be open or closed. During open sessions, representatives of the sponsor and 
development partner may be present, and information is provided and discussed in a blinded 
manner. During closed sessions, the only participants are members of the IDMC and the 
designated unblinded statistician (if approved to be present). 
If there is a request to unblind any individual treatment assignment, a written request from the 
IDMC (as a committee), signed by the IDMC chairperson, should be made to the unblinded 
statistician. The appropriate medical and operational personnel will be notified but will not 
receive the unblinded treatment information. Any use of unblinded treatment assignments should 
be clearly documented and reported to the sponsor at study termination.
The IDMC chairperson will communicate with Nuvelution TS Pharma in regard to issues 
resulting from the conduct and clinical aspects of the study. Nuvelution TS Pharma and Syneos 
Health will work closely with the committee to provide the necessary data for review.
The conduct and specific details regarding the IDMC sessions and requests to unblind any 
blinded treatment assignment are outlined in the IDMC charter.
3.8.
Investigational Medicinal Product and Placebo Used in the Study
The IMP is a matrix formulation and is designed as a gastro-erosional tablet to be administered 
with food and should not be taken on an empty stomach. The IMP is coated with a white 
polymer coating to aid in swallowing. TEV-50717 tablets have been manufactured according to 
current Good Manufacturing Practice regulations. 
During the open-label period, TEV-50717 tablets are available in the following dose strengths: 6, 
9, and 12 mg. Each dose strength will have a marking of SD 6, SD 9, and SD 12 corresponding 

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
58
to the dose strength and a distinct color: 6 mg – purple, 9 mg – blue, and 12 mg – beige. The 
IMP will be supplied in 20- or 60-count tablets per dose strength per bottle.
Each bottle will contain a sufficient supply of drug until the next specified visit/telephone 
contact, plus overage to account for potential delays in study visits. 
A more detailed description of administration procedures is given in Section 5.1.
During the randomized drug withdrawal and re-titration periods, TEV-50717 tablets are available 
in the following dose strengths: 6, 9, 12, 15, and 18 mg, all of which are identical in size, shape, 
and color (white). The IMP will be supplied in 20-count bottles.
Patients who receive TEV-50717 during the randomized drug withdrawal period will remain on 
their maintenance dose of blinded active IMP from the start of week 31 to the start of week 34; 
those assigned to placebo during the randomized drug withdrawal period will undergo blinded 
re-titration from the start of week 31 to the start of week 34 back to their previously established 
maintenance dose from the end of week 28. Note that, because IMP is dispensed for 2-week 
periods, patients will use blinded bottles through the end of week 34; however, all patients will 
be known to be on active treatment at the start of week 34. 
3.9.
Drug Supply and Accountability
3.9.1.
Drug Storage and Security
The IMP (TEV-50717) should be stored protected from light, at a controlled room temperature, 
20°C to 25°C (68°F to 77°F); however, storage between 15°C and 20°C (59°F to 68°F) is 
acceptable if there is no alternative. The IMP should be stored in a dry, securely locked, 
substantially constructed cabinet or enclosure, with access limited to authorized staff.
3.9.2.
Drug Accountability
Each IMP shipment to the site will include a packing slip listing the contents of the shipment, 
drug return instructions, and any applicable forms. 
The investigator is responsible for ensuring that deliveries of IMP and other study materials from 
the sponsor are correctly received, recorded, handled, and stored safely and properly in 
accordance with the local regulations, and used in accordance with this protocol. 
A record of IMP accountability (ie, IMP and other materials received, used, retained, returned, or 
destroyed) must be prepared and signed by the principal investigator or designee, with an 
account given for any discrepancies. Empty, partially used, and unused IMP will be disposed of, 
as agreed with the sponsor/development partner.
3.10.
Duration of Patient Participation and Justification
For patients rolling over from Study SD-809-C-17, this study will consist of a 4-week screening 
period (up to 31 days) and up to 54 weeks of treatment. All participating patients are expected to 
participate in this study for its entire duration, which is a minimum of 56 weeks (for those rolling 
over from Study SD-809-C-17, this can be up to 60 weeks). Patients will have a follow-up 
telephone contact to evaluate safety 1 week after the end of the washout period (2 weeks after 
their last dose of IMP). 

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
59
See Section 12.4 for the definition of the end of the study.
3.11.
Stopping Rules and Discontinuation Criteria
There are no formal rules for early termination of this study. During the conduct of the study, 
serious adverse events will be reviewed (see Section 7.1.5) as they are reported from the 
investigational center to identify safety concerns. The study may be terminated by the sponsor at 
any time. 
A patient may discontinue participation in the study at any time for any reason (eg, lack of 
efficacy, consent withdrawn, and adverse event); every effort should be undertaken to find out 
the reason for discontinuation. The investigator and/or sponsor can withdraw a patient from the 
study at any time for any reason (eg, protocol violation or deviation as defined in Section 11.1.2, 
noncompliance, or adverse event). 
3.12.
Source Data Recorded on the Case Report Form
All patient data must have supportive original source documentation in the medical records, or 
equivalent, before they are transcribed onto the CRF. Data may not be recorded directly onto the 
CRF and considered as source data unless the sponsor provides written instructions specifying 
which data are permitted to be recorded directly onto the CRF, such as eScales. 
If patient data are processed from other vendors (eg, clinical laboratory, central ECG, diary data), 
the results will be sent to the investigational center, where they will be retained but not entered 
into the CRF. These data may also be sent electronically to the sponsor (or organization 
performing data management) for direct use with the clinical database (see Section 13.1). All 
clinical patient data from other vendors will be available to the investigator.
The CRFs are filed in the sponsor’s central file after study completion. 
3.13.
Study Procedures and Assessments
Study procedures and assessments with their time points are presented in Table 1. During a visit, 
study procedures and assessments should be performed in the order specified in the study 
manual.
Detailed by-visit information is provided in the sections following the table. Detailed 
descriptions of each assessment are provided in Section 6 (efficacy assessments) and Section 7
(safety assessments).

a Assessments to occur at end of study week (±3 days).
b At the week 28 visit, the patients will be randomized 2:1 to their current dose of TEV-50717 or placebo in order to check for return of symptoms.
c For patients who withdraw prematurely, an early termination visit should be conducted as soon as possible after the last dose of IMP. All patients who discontinue early will 
have a follow-up telephone contact for safety evaluation 2 weeks after their last dose of IMP; evaluations will be as described for week 54 visit.
d This visit is a telephone contact for safety evaluation.
e Weight must be measured with shoes and outerwear off. Before pulse and BP are measured, the patient must be in a supine or semi erect/seated position and resting for at least 
5 minutes (the same position and arm should be used each time vital signs are measured for a given patient).

p IMP will be dispensed in the clinic; patients will receive doses for 2 weeks (current dose level and next dose level, when applicable [week 30 and week 32 visits]) to cover the 
telephone contacts. Because IMP for Part B is dispensed then, the week 28 visit (Day 196) is considered the first day of the randomized withdrawal period, although the patient 
will begin taking blinded IMP on Day 197. When applicable, the site will determine titration (ie, starting the next dose) for the patient by telephone. See Table 3 for dosing 
titration based on the patient’s previously established maintenance dose at the end of Part A.
q Patients will receive enough doses to cover treatment until the following in-clinic visit.
r Contact IRT if IMP assignment or adjustment is required.

Procedures for Screening and Enrollment (Visit 1)
Informed consent/assent, depending on the child’s age, as appropriate, will be obtained before 
any study procedures are performed. For patients rolling over from Study TV50717-CNS-30046 
or Study TV50717-CNS-30060, informed consent/assent, as appropriate, may be obtained prior 
to the day 1 visit, up to 4 weeks in advance of open-label study participation.
For patients rolling over from Study TV50717-CNS-30046 or Study TV50717-CNS-30060, 
screening data will be obtained from the parent study (see Table 1). Informed consent/assent, as 
appropriate, must be given before any procedures related solely to Study TV50717-CNS-30047 
are performed.
For patients from Study SD-809-C-17: 
All screening procedures will be performed for patients rolling over from Study SD-809-C-17, as 
they will have been off IMP for several months at the time of enrollment into this study 
(TV50717-CNS-30047). A signed and dated informed consent form will be obtained from the
parent/legally acceptable representative, and a signed and dated assent, depending on the child’s 
age, as appropriate, will be obtained from each patient before any screening procedures 
commence, according to national laws and local IEC/IRB requirements. Parents/legally 
acceptable representatives will acknowledge and agree to the possible use of this information for 
the study by giving informed consent.
A patient who is screened but not enrolled may be rescreened 1 time if there is a change in the 
patient’s medical background, a modification of study entry criteria, or other relevant change. 
(Note: Details of rescreening must be approved and documented by the medical monitor and/or 
CST team.)
The screening visit will take place not more than 31 days before the day 1 visit. The screening 
visit may be conducted over 2 separate visits at the discretion of the investigator. The following 
procedures will be performed at the screening visit for patients from Study SD-809-C-17:

obtain written informed consent (and assent, depending on the child’s age, as 
appropriate) before any other study-related procedures are performed

conduct clinic visit

review eligibility (inclusion and exclusion) criteria

inform patients of study restrictions and compliance requirements


YGTSS Rater Certification
All investigators and subinvestigators who will be administering the YGTSS from screening 
through the end of study visit must undergo and pass a Rater Certification Program which will be 
provided separately from this protocol. Every effort must be made to ensure that the same 
certified rater administers the YGTSS to a specific patient at all visits where this scale is 
administered, especially at day 1 and at weeks 28, 30, and 54/early termination visits. However, 
if due to unforeseen circumstances the same rater is absolutely unavailable to complete a visit 
rating, the YGTSS can be administered only by another certified individual from that study site.

Procedures During Investigational Medicinal Product Treatment
3.13.3.1.
Titration Period (Weeks 1 to 7)
3.13.3.1.1. Telephone Contacts (Weeks 1, 3, 5, and 7)
Patients will be contacted by telephone to evaluate tic reduction and adverse events. Dose 
adjustment will be made by the investigator after telephone contact with the patient and 
caregiver/adult. The following procedures/assessments will be performed via telephone contact
at weeks 1, 3, 5, and 7:

assess IMP accountability/compliance/supply status to ensure the patient has adequate 
tablets, inform the patient if they should titrate, and remind them to bring used and 
unused IMP bottles to the next in-clinic visit

inquire about adverse events

review concomitant medications
If a patient experiences an adverse event that is reported during a telephone contact and is 
probably related to the IMP, he or she will be brought to the clinic for evaluation (see 
Section 3.13.5). Based on the telephone evaluation, the investigator will determine whether, with 
the medication already provided, the patient should titrate up, stay at that dose, or reduce the 
dose. If additional IMP is required, it would be ordered from the distributor and provided to the 
patient at an unscheduled visit.

CNS-30060, these data will be obtained from the screening visit of the parent study).
4.3.
Justification for Key Inclusion and Exclusion Criteria
Inclusion and exclusion criteria have been designed to minimize the risk to patients while 
maintaining a consistent level of TS symptoms to allow detection and analysis of a drug effect. 
Exclusion criteria were designed to exclude patients with concomitant conditions that may 
increase their risk to drug treatment.
4.4.
Withdrawal Criteria and Procedures
In accordance with the Declaration of Helsinki (and in accordance with the applicable country’s 
acceptance), each patient is free to withdraw from the study at any time. The investigator also 
has the right to withdraw a patient from the study if any of the following events occur:
a.
intercurrent illness

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
81
b. adverse events (any patient who experiences an adverse event may be withdrawn 
from the study or from study treatment at any time at the discretion of the investigator 
or sponsor as indicated in Section 7.1.7)
c.
pregnancy (see Section 7.3)
d. other reasons concerning the health or well-being of the patient
e.
lack of cooperation
f.
post-baseline QTcF value >500 msec or change from baseline >60 msec (as described 
in Section 7.1.7). The investigator should repeat the ECG assessment twice and 
compare the average of the 2 pre-treatment QTcF values (ie, the parent study baseline 
and screening values for patients rolling over from Study TV50717-CNS-30046 or 
Study TV50717-CNS-30060 or the day 1 and screening values from the current study 
for patient[s] who completed Study SD-809-C-17) to the average of the 3 post-
baseline QTcF values. The IMP must be stopped for any confirmed post-day 1 QTcF 
value >500 msec or increase from baseline >60 msec.
g. when a blind is broken due to safety concerns (see Section 3.6.2). If a patient is 
unblinded by mistake, the investigator should discuss with the medical monitor 
whether or not the patient should be withdrawn.
h. if the investigator or the sponsor determines that the patient is not in compliance with 
the study protocol, the investigator and the sponsor should determine whether the 
patient should be withdrawn from the study (Section 5.4).
In addition, a patient may be withdrawn from the study as described in 
Sections 3.11, 3.6, 5.4, 7.1.7, and 3.13. 
Should a patient decide to withdraw after administration of IMP, or should the investigator 
decide to withdraw the patient, all efforts will be made to complete and report all observations up 
to the time of withdrawal. A complete final evaluation of the patient’s withdrawal should be 
made as soon as possible after the last dose of IMP, and an explanation should be given as to 
why the patient is withdrawing or being withdrawn from the study. Assessments to be conducted 
at the early termination visit are described in Section 3.13.3.2.1.
The reason for and date of withdrawal from the study must be recorded on the source 
documentation and transcribed onto the CRF. If a patient withdraws consent, every attempt will 
be made to determine the reason. If the reason for withdrawal is an adverse event or a potentially 
clinically significant abnormal laboratory test result, monitoring will be continued at the 
discretion of the investigator (eg, until the event has resolved or stabilized, until the patient is 
referred to the care of a health care professional, or until a determination of a cause unrelated to 
the IMP or study procedure is made). The specific event or test result must be recorded on the 
source documentation and transcribed onto the CRF. 
All patients who discontinue early will have a follow-up telephone contact for safety evaluation 
2 weeks after their last dose of IMP (Section 3.13.4.2).

TREATMENT OF PATIENTS
5.1.
Investigational Medicinal Products Administered During the Study
During the open-label period, TEV-50717 tablets are available in the following dose strengths: 6, 
9, and 12 mg. Patients will receive twice daily dosing for up to 54 weeks (those on the 6-mg dose 
will receive once-daily dosing), with an initial 7-week titration period to allow for optimal dose 
selection. 
During the randomized drug withdrawal and re-titration period, TEV-50717 tablets are available 
in the following dose strengths: 6, 9, 12, 15, and 18 mg, all of which are identical in size, shape, 
and color (white). The IMP will be supplied in 20-count bottles. The placebo tablets and 
packaging will match those for TEV-50717. 
Patients who receive TEV-50717 during the randomized drug withdrawal period will remain on 
their maintenance dose of blinded active IMP from the start of week 31 to the start of week 34; 
those assigned to placebo during the randomized drug withdrawal period will undergo blinded 
re-titration from the start of week 31 to the start of week 34 back to their previously established 
maintenance dose from the end of week 28. Note that, because IMP is dispensed for 2-week 
periods, patients will use blinded bottles through the end of week 34; however, all patients will 
be known to be on active treatment at the start of week 34. 
5.1.1.
Drug Administration
IMP (see Section 3.9) will be administered as oral tablets at a starting dose of 6 mg once daily. 
Titration schemes based on body weight on day 1 are shown in Table 2. The maximum daily 
dose is determined by body weight and CYP2D6 impairment status on day 1 (see Table 2). 
Although dose adjustments can be made up to and including the week 7 telephone call, if a stable 
dose is reached before then, the patient should continue taking that dose for the remainder of the 
titration period. If a patient experiences depression, suicidal ideation or behavior, anxiety, 
akathisia, parkinsonism, somnolence, any other adverse event that interferes with daily activity, 
or adverse event that is related to IMP, the investigator will determine if a dose reduction or 
suspension is necessary. At the end of the titration period, the patient’s dose will be established 
for the maintenance period. If a patient experiences an adverse event during the maintenance 
period and the investigator believes a dose reduction is warranted, the dose may be reduced.
Dose adjustments of TEV-50717 (upward or downward) may be made during the maintenance 
period, if necessary, but not more often than every 5 days and only in increments of 6 mg.
IMP will be dispensed in the clinic. Patients should take their first dose in the evening on day 1 
after their day 1 clinic visit. Patients will receive sufficient doses to last until the next visit.
IMP will be administered as follows:

IMP should be swallowed whole and taken with food. Tablets should be taken with 
food (eg, a snack) and should not be taken on an empty stomach.

Dosing will be based on body weight and CYP2D6 impairment status, as shown in 
Table 2.

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
83

The total daily dose, as provided in Table 2, is divided into a twice daily 
administration. The starting dose is 6 mg in all patients. Daily doses will be 
administered twice daily, approximately 8 to 10 hours apart during the day (those on 
the 6-mg dose will have once-daily dosing). A minimum of 6 hours should elapse 
between doses. If a patient misses a dose and it is within 6 hours of their next dose, 
the missed dose should be skipped.

After week 1, dose increases may not occur more frequently than once every 5 days.

Dose reductions, if required, should be in increments of 6 mg. If more than 1 dose 
reduction is required for an adverse event, the medical monitor should be 
notified.

After dose adjustment, if the maintenance dose for a patient is 6 mg, the dose should 
be taken once a day in the morning with food.

During the titration period, the dose of the IMP should be adjusted according to 
Table 2 to identify a dose level that optimally reduces tics (as determined by the 
investigator, in consultation with the patient and caregiver/adult) and is well tolerated.
A dose cap for impaired patients is prespecified by the IRT and presented in Table 2.

After week 24, patient dose should be kept stable, if possible, until beginning Part B.

During the randomized drug withdrawal period, the patient will continue to receive 
their current dose of TEV-50717 or receive matching placebo until returning to their
dose of TEV-50717 at the start of week 31 (patients who receive TEV-50717 during 
the randomized drug withdrawal period will remain on their maintenance dose of 
blinded active IMP from the start of week 31 to the start of week 34; those assigned 
to placebo during the randomized drug withdrawal period will undergo blinded 
re-titration from the start of week 31 to the start of week 34 back to their previously 
established maintenance dose from the end of week 28). During the re-titration
period, the dose of the IMP should be adjusted according to Table 3.

Following re-titration, the dose of IMP should be kept stable, if possible, but changes 
can be made as described for Part A.
IMP will be packaged in bottles and provided for patients to take at home (see Section 3.8).

5.2.
Restrictions
Medications prohibited before or during the study are described in Section 5.3. 
While patients receiving strong CYP2D6 inhibitors such as paroxetine, fluoxetine, and 
bupropion on day 1 may be enrolled into this study, the removal of strong CYP2D6 inhibitors 
during treatment is discouraged as this would have an effect on exposure to active circulating 
drug. If the removal of a strong CYP2D6 inhibitor is required from a clinical perspective, the 
medical monitor should be contacted so an appropriate change in IMP can be made. The use of 
quinidine and terbinafine are prohibited (see Appendix A, Table 9).
Restrictions in regard to sexual activity and required laboratory values are provided in the 
inclusion and exclusion criteria.
As with other VMAT2 inhibitors (tetrabenazine, reserpine), patients should be advised that the 
concomitant use of alcohol or other sedating drugs with TEV-50717 may have additive effects 
and cause or worsen somnolence. Given the age of the study population, the use of alcohol 
during this study is prohibited. 
Patients should be advised not to drive a car or operate dangerous machinery until they 
understand how TEV-50717 affects them.
Use of illicit drugs is prohibited from the time of signing of the informed consent/assent form 
and throughout study participation.
Patients may not donate blood from the time of informed consent/assent, while taking the IMP, 
and for 14 days after the last dose.
5.3.
Prior and Concomitant Medication or Treatment
Any prior or concomitant therapy, medication, or procedure a patient receives during IMP
administration and up to the end of the study period, including follow-up, will be recorded on the 
CRF. Generic or trade name, indication, and dosage will be recorded. In addition, only for 
patients who completed Study SD-809-C-17, any prior or concomitant therapy, medication, or 
procedure a patient has had within 3 months before IMP administration will be recorded on the 
CRF. The sponsor will encode all therapy and medication according to the World Health 
Organization drug dictionary.
At each clinic visit after the screening visit, the investigator will ask patients whether they have 
taken any medications (other than IMP), including over-the-counter medications, vitamins, or 
herbal or nutritional supplements, since the previous visit. Parents/patients will be instructed 
during the course of the study to notify the investigator if any new medication is 
prescribed/administered, including over-the-counter medications. Any prescribed/administered
medication should be reviewed with the investigator. Indication, dosage, and start and end dates 
should be entered on the CRF. 
Medications that are allowed, provided that conditions outlined in the table are met, are shown 
in Appendix A, Table 6.
The medical monitor must be contacted if a patient is receiving (or has to begin or stop receiving
during the study) a medication that is associated with QTc prolongation or that is a known strong 
CYP inhibitor. Addition of a strong CYP inhibitor is prohibited.

86
Prohibited antipsychotic drugs medications are listed in Appendix A, Table 7, while prohibited 
medications that are associated with QTc prolongation are listed in Appendix A, Table 8.
5.4.
Procedures for Monitoring Patient Compliance
The investigator will be responsible for monitoring patient compliance. A check of IMP
compliance will be performed during each visit after the initial dispensation of IMP, and IMP
accountability records will be completed. If the investigator or the sponsor determines that the 
patient is not in compliance with the study protocol, the investigator and the sponsor should 
determine whether the patient should be withdrawn. The IEC/IRB should be notified as required 
by national and local regulations.
5.5.
Dose Reduction and Temporary Investigational Medicinal Product
Discontinuation
Dose Reduction
If a patient experiences a “clinically significant” adverse event that is attributed to IMP, the 
investigator will determine if a dose reduction or suspension is necessary. Dose adjustments 
should be made based on all available information, including the patient and caregiver/adult
reports of adverse events and tic reduction, the clinical assessment of safety and efficacy by the 
investigator, and information from rating scales. If more than 1 dose reduction is required for 
an adverse event, the medical monitor must be notified. After dose adjustment, if the 
maintenance dose for a patient is 6 mg, the dose should be taken once a day in the morning with 
food (other dose levels are taken twice daily).
If the determination that a patient requires a dose reduction or suspension is made during a 
telephone contact, an unscheduled clinic visit should be conducted as soon as practicable 
thereafter.
Dose Suspension
Suspension of study medication for up to 1 week, if warranted for patient safety, is allowed. If 
the patient restarts study medication within 7 days of suspension, the full dose of TEV-50717 
may be resumed without titration. Suspensions of study medication for adverse events must 
be reviewed with the medical monitor before therapy is restarted. If a subject’s serum 
potassium or magnesium were tested and found to be below the lower limit of normal and 
clinically significantly, the laboratory test should be repeated at least once. If the abnormality in 
the repeated laboratory test is consistent with the prior laboratory test, the IMP must be 
suspended. The medical monitor must be contacted to determine the appropriate investigation 
and treatment. TEV-50717 may only be restarted once serum potassium or magnesium have 
normalized.
The reason for a dose reduction or suspension must be clearly documented.
If a dose reduction or suspension occurs before a scheduled clinic visit, the clinic visit will 
be postponed so that efficacy evaluations can be performed at least 5 days after the change.
The patients who restart IMP treatment will follow the visit schedule as outlined in Table 1. 
Patients who withdraw from the study will proceed as described in Section 4.4.

Efficacy and Exploratory Measures
 
 
 
 
 
 
 
 
 
6.1.1.
Tourette Syndrome–Clinical Global Impression
TS-CGI is administered on day 1 (ie, week 13 data from Study TV50717-CNS-30046 or week 9 
data from Study TV50717-CNS-30060) and weeks 4, 8, 15, 28, 34, 41, 54, and 55. The TS-CGI 
scale is a 7-point Likert scale that allows the clinician to use all available information to assess 
the impact of tics on the patient’s quality of life. The TS-CGI is rated as follows: 1 (normal), 
2 (borderline), 3 (mild), 4 (moderate), 5 (marked), 6 (severe), and 7 (extreme).
A reference sample is provided in Appendix H.
6.1.2.
Tourette Syndrome-Patient Global Impression of Impact
The TS-PGII is administered on day 1 (ie, week 13 data from Study TV50717-CNS-30046 or 
week 9 data from Study TV50717 CNS-30060) and weeks 4, 8, 15, 28, 34, 41, 54, and 55. Input 
from the caregiver/adult is permitted.
The TS-PGII is a single-item questionnaire that asks the patient to assess the degree of impact 
due to current tics. The TS-PGII uses a 5-point scale, ranging from not at all (1) to very 
much (5), to assess overall response to therapy. In general, patient-rated global measures of 
change have face validity and have been shown to correlate with disability for a number of 
chronic conditions.

Child and Adolescent Gilles de la Tourette Syndrome-Quality of Life Scale
The C&A-GTS-QOL is administered on day 1 and weeks 6, 28, 34, and 54. Children 13 years of 
age and under must be interviewed in conjunction with the caregiver/adult. Children 13 years of 
age and under may be interviewed separately or jointly with the caregiver/adult as appropriate or 
defined by the scale. Questions should be directed to the child, but the caregiver/adult should be 
encouraged to add relevant information.
The C&A-GTS-QOL is a 27-item questionnaire specific to TS patients that asks the patient to 
assess the extent to which their quality of life is impacted by their symptoms. The C&A-
GTS-QOL contains 4 subscales (psychological, physical, obsessional, and cognitive) and uses a 
5-point Likert scale ranging from no problem to extreme problem. Patients will also be asked 
how satisfied they feel overall with their life at that moment by using a VAS scale between 0 and 
100 (Su et al 2017).

ASSESSMENT OF SAFETY
In this study, safety will be assessed by qualified study personnel by evaluating reported adverse 
events, clinical laboratory test results, vital signs measurements, ECG findings, physical 
examination findings (including body weight and height measurements), use of concomitant 
medication, neurological examination, C-SSRS, and CDI-2.
7.1.
Adverse Events
7.1.1.
Definition of an Adverse Event
Any untoward medical occurrence in a patient or clinical investigation subject administered a 
pharmaceutical product and which does not necessarily have to have a causal relationship with 
this treatment.
An adverse event can, therefore, be any unfavorable and unintended physical sign, symptom, or 
laboratory parameter that develops or worsens in severity during the course of this study, or 
significant worsening of the disease under study, or of any concurrent disease, whether or not 
considered related to the IMP, TEV-50717. A new condition or the worsening of a pre-existing 
condition will be considered an adverse event. Stable chronic conditions (such as arthritis) that 
are present before study entry and do not worsen during this study will not be considered adverse 
events.
Accordingly, an adverse event can include any of the following:

intercurrent illnesses

physical injuries

events possibly related to concomitant medication

significant worsening (change in nature, severity, or frequency) of the disease under 
study or other pre-existing conditions

drug interactions

events occurring during diagnostic procedures or during any washout phase of this
study

laboratory or diagnostic test abnormalities that result in the withdrawal of the patient 
from the study, are associated with clinical signs and symptoms or a serious adverse 
event, or require medical treatment or further diagnostic work-up, or are considered 
by the investigator to be clinically significant (Note: Abnormal laboratory test results 
at the screening visit that preclude a patient from entering the study or receiving IMP
are not considered adverse events.)
7.1.2.
Recording and Reporting of Adverse Events
For recording of adverse events, the study period is defined for each patient as that time period 
from signature of the informed consent/assent form to the end of the follow-up period. The 
follow-up period is defined as 2 weeks after the last dose of IMP.

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
92
All adverse events that occur during the defined study period must be recorded both on the 
source documentation and the CRF, regardless of the severity of the event or judged relationship 
to the IMP. For serious adverse events, the serious adverse event form must be completed, and 
the serious adverse event must be reported immediately (see Section 7.1.5.3.1). The investigator 
does not need to actively monitor patients for adverse events after the defined period. Serious 
adverse events occurring to a patient after the treatment of that patient has ended should be 
reported to the sponsor if the investigator becomes aware of them, following the procedures 
described in Section 7.1.5.3.1.
At each contact with the patient, the investigator or designee must question the patient about 
adverse events by asking an open-ended question such as “Have you had any unusual symptoms 
or medical problems since the last visit? If yes, please describe”. All reported or observed signs 
and symptoms will be recorded individually, except when considered manifestations of a 
medical condition or disease state. A precise diagnosis will be recorded whenever possible. 
When such a diagnosis is made, all related signs, symptoms, and any test findings will be 
recorded collectively as a single diagnosis on the CRF and, if it is a serious adverse event, on the 
serious adverse event form.
The clinical course of each adverse event will be monitored at suitable intervals until resolved,
stabilized, or returned to baseline; or until the patient is referred for continued care to a health 
care professional; or until a determination of a cause unrelated to the IMP or study procedure is 
made.
The onset and end dates, duration (in case of adverse event duration of less than 24 hours), action 
taken regarding IMP, treatment administered, and outcome for each adverse event must be 
recorded both on the source documentation and the CRF.
The relationship of each adverse event to IMP and study procedures, and the severity and 
seriousness of each adverse event, as judged by the investigator, must be recorded as described 
below.
Further details are given in the Safety Monitoring Plan.
7.1.3.
Severity of an Adverse Event
The severity of each adverse event must be recorded as 1 of the following:
Mild:
No limitation of usual activities
Moderate: Some limitation of usual activities
Severe:
Inability to carry out usual activities

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04

7.1.4.
Relationship of an Adverse Event to the Investigational Medicinal Product
The relationship of an adverse event to the IMP is characterized as follows:
Term
Definition
Clarification
No 
reasonable 
possibility
(not related)
This category applies to adverse 
events that, after careful 
consideration, are clearly due to 
extraneous causes (disease, 
environment, etc) or to adverse 
events that, after careful medical 
consideration at the time they are 
evaluated, are judged to be 
unrelated to the IMP.
The relationship of an adverse event may be 
considered “no reasonable possibility” if it is clearly 
due to extraneous causes or if at least 2 of the 
following apply:

It does not follow a reasonable temporal 
sequence from the administration of the 
IMP.

It could readily have been produced by the 
patient’s clinical state, environmental or 
toxic factors, or other modes of therapy 
administered to the patient.

It does not follow a known pattern of 
response to the IMP.

It does not reappear or worsen when the 
IMP is re-administered.
Reasonable 
possibility
(related)
This category applies to adverse 
events for which, after careful 
medical consideration at the time 
they are evaluated, a connection 
with the administration of IMP
cannot be ruled out with certainty.
The relationship of an adverse event may be 
considered “reasonable possibility” if at least 2 of 
the following apply:

It follows a reasonable temporal sequence 
from administration of the IMP.

It cannot be reasonably explained by the 
known characteristics of the patient’s 
clinical state, environmental or toxic factors,
or other modes of therapy administered to 
the patient.

It disappears or decreases on cessation or 
reduction in dose. There are important 
exceptions when an adverse event does not 
disappear after discontinuation of the IMP, 
yet an IMP relationship clearly exists.

It follows a known pattern of response to the 
IMP.
7.1.5.
Serious Adverse Events
For recording of serious adverse events, the study period is defined for each patient as the time 
period from signing of the informed consent/assent form to the end of the follow-up period as 
defined in Section 7.1.2. Serious adverse events occurring in a patient after the end of the follow-
up period should be reported to the sponsor if the investigator becomes aware of them, following 
the procedures described in Section 7.1.5.3.1.
7.1.5.1.
Definition of a Serious Adverse Event
A serious adverse event is an adverse event occurring at any dose that results in any of the 
following outcomes or actions:

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
94

results in death

is life threatening (ie, the patient was at risk of death at the time of the event); it does 
not refer to an event which hypothetically might have caused death if it were more 
severe

requires inpatient hospitalization or prolongation of existing hospitalization, which 
means that hospital inpatient admission or prolongation of hospital stay were required 
for treatment of an adverse event, or that they occurred as a consequence of the event. 
Hospitalizations scheduled before the patient signed the informed consent form will 
not be considered serious adverse events, unless there was worsening of the 
preexisting condition during the patient’s participation in this study.

results in persistent or significant disability/incapacity (refers to a substantial 
disruption of one’s ability to conduct normal life functions)

is a congenital anomaly/birth defect

is an important medical event that may not result in death, be life-threatening, or 
require hospitalization, but may jeopardize the patient and may require medical 
intervention to prevent one of the outcomes listed in this definition
Examples of such events are intensive treatment in an emergency room or at home for 
allergic bronchospasm; blood dyscrasias or convulsions that do not result in 
hospitalization; or the development of drug dependency or drug abuse. Note: Any 
suspected transmission of an infectious agent via a medicinal product is considered an 
important medical event.
All occurrences of possible drug-induced liver injury that meet Hy’s law criteria, defined as all
of the below, must be reported by the investigator to the sponsor as a serious adverse event:

alanine aminotransferase (ALT) or aspartate aminotransferase (AST) increase of 
>3 × the upper limit of normal (ULN)

total bilirubin increase of >2 × ULN

absence of initial findings of cholestasis (ie, no substantial increase of ALP)
An adverse event that does not meet any of the criteria for seriousness listed above will be 
regarded as a nonserious adverse event.
7.1.5.2.
Expectedness
A serious adverse event that is not included in the Adverse Reaction section of the relevant 
reference safety information (RSI) by its specificity, severity, outcome, or frequency is 
considered an unexpected adverse event. The RSI for this study is the IB.
A serious adverse event that is not included in the Listing of Adverse Reactions in the RSI by its 
specificity, severity, outcome, or frequency is considered an unexpected adverse event.
The sponsor’s Global Patient Safety and Pharmacovigilance will determine the expectedness for 
all serious adverse events.

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
95
For the purpose of SUSAR reporting, the version of the IB at the time of occurrence of the 
SUSAR applies.
7.1.5.3.
Reporting a Serious Adverse Event
7.1.5.3.1. Investigator Responsibility
To satisfy regulatory requirements, all serious adverse events that occur during the study,
regardless of judged relationship to administration of the IMP, must be reported by the 
investigator according to the instructions provided on the serious adverse event form. The event 
must be reported within 24 hours of when the investigator learns about it. Completing the serious 
adverse event form and reporting the event must not be delayed, even if not all the information is 
available. The investigator does not need to actively monitor patients for adverse events once this 
study has ended.
Serious adverse events occurring to a patient after the last administration of IMP should be 
reported to the sponsor if the investigator becomes aware of them.
The serious adverse event form should be sent to the local safety officer (LSO) or designee (a 
contract research organization in a country without a sponsor LSO) (contact information is in the 
Clinical Study Personnel Contact Information section); the LSO will forward the report to the 
sponsor’s Global Patient Safety and Pharmacovigilance.
The following information should be provided to record the event accurately and completely:

study number

investigator and investigational center identification

patient number

onset date and detailed description of adverse event

investigator’s assessment of the relationship of the adverse event to the IMP (no 
reasonable possibility, reasonable possibility)
Additional information includes:

age and sex of patient

date of first dose of IMP

date and amount of last administered dose of IMP

action taken

outcome, if known

severity

explanation of assessment of relatedness

concomitant medication (including doses, routes of administration, and regimens) and 
treatment of the event

pertinent laboratory or other diagnostic test data

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
96

medical history

results of dechallenge/rechallenge, if known

for an adverse event resulting in death:

cause of death (whether or not the death was related to IMP)

autopsy findings (if available)
Each report of a serious adverse event will be reviewed and evaluated by the investigator and the 
sponsor to assess the nature of the event and the relationship of the event to the IMP, study 
procedures, and to underlying disease.
Additional information (follow-up) about any serious adverse event unavailable at the initial 
reporting should be forwarded by the investigator within 24 hours of when it becomes known to 
the same address as the initial report.
For all countries, the sponsor’s Global Patient Safety and Pharmacovigilance will distribute the 
Council for International Organizations of Medical Sciences (CIOMS) form/Extensible Markup 
Language (XML) file to the LSO/Syneos Health for submission to the competent authorities,
IEC/IRBs, and investigators, according to regulations. The investigator must ensure that the 
IEC/IRB is also informed of the event, in accordance with national and local regulations.
Note: Although pregnancy is not a serious adverse event, the process for reporting a pregnancy is 
the same as that for reporting a serious adverse event, but using the pregnancy form (see 
Section 7.3).
7.1.5.3.2. Sponsor Responsibility
If a serious unexpected adverse event is believed to be related to the IMP or study procedures, 
the sponsor will take appropriate steps to notify all investigators participating in sponsored 
clinical studies of TEV-50717 and the appropriate competent authorities (and IEC/IRB, as 
appropriate).
In addition to notifying the investigators and competent authorities (and IEC/IRB, as 
appropriate), other actions may be required, including:

altering existing research by modifying the protocol

discontinuing or suspending the study

modifying the existing consent form and informing all study participants of new 
findings


7.1.7.
Withdrawal Due to an Adverse Event
Any patient who experiences an adverse event may be withdrawn from the study or from IMP at 
any time at the discretion of the investigator. If a post-day 1 QTcF value >500 msec or change 
from baseline (Study TV50717-CNS-30046 or Study TV50717-CNS-30060) or day 1 (Study 
SD-809-C-17), as appropriate (see Section 9.7.2) >60 msec is found, the investigator should 
repeat the ECG assessment twice and compare the average of the 2 pre-treatment QTcF values 
(ie, the parent study baseline and screening values for patients rolling over from Study TV50717-
CNS-30046 or Study TV50717-CNS-30060 or the day 1 and screening values from the current 
study for patient[s] who completed Study SD-809-C-17) to the average of the 3 post-day 1 QTcF 
values. The IMP must be stopped for any confirmed post-day 1 QTcF value >500 msec or 
increase from baseline (Study TV50717-CNS-30046 or Study TV50717-CNS 30060) or day 1 
(Study SD-809-C-17) >60 msec. If a patient is withdrawn wholly or in part because of an 
adverse event, both the adverse events page and termination page of the CRF will be completed 
at that time.
The patient will be monitored at the discretion of the investigator (eg, until the event has 
resolved or stabilized, until the patient is referred to the care of a health care professional, or 
until a determination of a cause unrelated to the IMP or study procedure is made). The 
investigator must inform the clinical project physician (CPP)/clinical leader as soon as possible 
of any patients who are being considered for withdrawal due to adverse event(s). Additional 
reports must be provided when requested.
If a patient is withdrawn from the study for multiple reasons that include adverse events, the 
termination page of the CRF should indicate that the withdrawal was related to an adverse event. 
An exception to this requirement will be the occurrence of an adverse event that, in the opinion 
of the investigator, is not severe enough to warrant discontinuation but that requires the use of a 
prohibited medication, thereby requiring discontinuation of the patient. In such a case, the reason 
for discontinuation would be need to take a prohibited medication, not the adverse event.
7.1.8.
Protocol Deviations Because of an Adverse Event
If a patient experiences an adverse event or medical emergency, deviations from the protocol 
may be allowed on a case-by-case basis. To ensure patient safety, after the event has stabilized or 
treatment has been administered (or both), the investigator or other physician in attendance must 
contact the physician identified in the Clinical Study Personnel Contact Information section of 
this protocol as soon as possible to discuss the situation. The investigator, in consultation with 
the sponsor, will decide whether the patient should continue to participate in the study.
7.2.
Psychometric Rating Scales
Site-administered safety scales include the MINI Kid and C-SSRS, and self-administered safety 
scales include the CDI-2. 
7.2.1.
Mini International Neuropsychiatric Interview for Children and Adolescents, 
(version 6.0)
Select MINI Kid modules are administered at screening (only for patients who completed 
Study SD-809-C-17). Children 13 years of age and under may be interviewed separately or 
jointly with the caregiver/adult as appropriate or defined by the scale. For children over 13 years 

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
98
of age, caregiver/adult involvement is strongly encouraged. Questions should be directed to the 
child, but the caregiver/adult should be encouraged to add relevant information.
The MINI Kid is a short questionnaire to be administered by a trained clinician. The MINI Kid 
assesses symptoms of psychiatric disorders as outlined in the International Classification of 
Diseases-10 and the DSM in children 6 to 17 years of age by self-report. For children under 
13 years old, the patient may be interviewed separately or jointly with the caregiver/adult as 
appropriate or defined by the scale, and the caregiver/adult is encouraged to participate when 
needed. The MINI Kid (version 6.0) is composed of 24 modules overall, and questions are 
largely yes-or-no questions. The current study will focus on 8 modules: Major Depressive 
Episode (Module A), (Hypo) Manic Episode (Module D), OCD (Module J), Alcohol 
Dependence/Abuse (Module L), Substance Dependence/Abuse (Non-alcohol; Module M), 
ADHD (Module O), Conduct Disorder (Module P), and Psychotic Disorders and Mood 
Disorders with Psychotic Features (Module R).
A reference sample is provided in Appendix C.
7.2.2.
Columbia-Suicide Severity Rating Scale
The C-SSRS children’s baseline/screening version assesses past and current suicidal ideations
and behaviors to determine suicide risk and is administered at screening. The C-SSRS children’s 
SLV scale is administered on day 1 (only for patients who completed Study SD-809-C-17) and 
weeks 2, 4, 8, 15, 28, 30, 34, 41, 54, and 55. Children 13 years of age and under may be 
interviewed separately or jointly with the caregiver/adult as appropriate or defined by the scale. 
For children over 13 years of age, caregiver/adult involvement is strongly encouraged. Questions 
should be directed to the child, but the caregiver/adult should be encouraged to add relevant 
information. The C-SSRS is administered through an interview by trained study personnel.
Suicidal ideation

Patients with a positive C-SSRS suicidal ideation score on either items 1 or 2 or a change 
on the CDI-2 Parent or Self-Report Profiles consistent with increasing depressive 
symptoms must be 1) discussed with the medical monitor, 2) re-evaluated within 2 to 3 
days in a clinic visit, and 3) treated according to the investigator’s medical judgment. 
Consultation with a child and adolescent psychiatrist or licensed child/adolescent mental 
health provider is advised, followed by close ongoing monitoring.

If patients endorse or report a C-SSRS suicidal ideation level of 3, 4, or 5, patients will be 
evaluated immediately by the study investigator and referred for psychiatric evaluation. 
The medical monitor will be immediately consulted. If it is determined by the 
investigator, after consultation with the medical monitor and the consulting psychiatrist, 
that exposure to the IMP may have contributed to this change in C-SSRS and/or 
increased depressive symptoms, IMP will be immediately discontinued and the patient 
terminated from the study. In cases where it is determined that IMP did not contribute to 
changes in depression or suicidality, the investigator will consult with the medical 
monitor, the consulting psychiatrist, and/or sponsor to determine whether the patient 
should continue in the study.

99
Suicidal behavior

Actual attempt: 

If patients report any suicidal behavior that is an actual attempt as assessed in the 
C-SSRS, they will be evaluated immediately by the study investigator, referred 
for psychiatric evaluation, and terminated from the study.

Interrupted attempt, aborted attempt, or Preparatory Acts or Behavior: 

If patients report any suicidal behavior that is interrupted, aborted, or preparatory 
as assessed in the C-SSRS, they will be evaluated immediately by the study 
investigator and referred for psychiatric evaluation. In cases where it is 
determined in the psychiatric evaluation that IMP did not contribute to changes in 
suicidal behavior, the investigator will consult with the medical monitor, the 
consulting psychiatrist, and/or sponsor to determine whether the patient should 
continue in the study.
A reference sample is provided in Appendix E.
7.2.3.
Children’s Depression Inventory, Second Edition, Parent and Self-Report 
Profiles
CDI-2 (Parent and Self-Report Profiles) is administered at screening and day 1 (only for patients 
who completed Study SD-809-C-17) and weeks 2, 4, 8, 15, 28, 30, 34, 41, 54, and 55. As the 
CDI-2 is designed for children 7 to 17 years of age, children 6 years of age on day 1 will not 
complete the Self-Report version; the caregiver/adult will complete the Parent version.
The CDI-2 Self-Report is a 28-item, self-report questionnaire assessing depressive symptoms in 
children 7 to 17 years of age with basic reading and comprehension skills. In the CDI-2, children 
are asked to choose 1 of 3 statements that most closely aligns with their feelings in the previous 
2 weeks. The questionnaire covers both the major and minor symptoms of depression as outlined 
in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Text Revision (Sun 
and Wang 2015).
The CDI-2 Parent is a 17-item questionnaire administered to parents to assess depression-related 
behaviors observed in their children. In the CDI-2 Parent, parents are asked to rate their child’s 
behaviors in the past 2 weeks on a 4-point Likert scale from “not at all” to “much or most of the 
time”. The questionnaire allows for the division of depressive symptoms into functional 
problems and emotional problems (Sun and Wang 2015).
A reference sample is provided in Appendix D.
7.3.
Pregnancy
Any female patient becoming pregnant during the study will discontinue IMP.
All pregnancies of female patients participating in the study that occur during the study, or 
within 14 days after the end of the study, are to be reported immediately to the physician 
identified in the Clinical Study Personnel Contact Information section of this protocol, and the 
investigator must provide the sponsor (LSO/Syneos Health) with the completed pregnancy form.

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
100
The process for reporting a pregnancy is the same as that for reporting a serious adverse event 
but using the pregnancy form (see Section 7.1.5.3).
The investigator is not required to report patients who are found to be pregnant between 
screening and day 1, provided no IMP was given. All female patients who become pregnant will 
be monitored for the outcome of the pregnancy (including spontaneous, elective, or voluntary 
abortion). If the pregnancy continues to term, the outcome (health of the infant up to 8 weeks of 
age), including details of birth and presence or absence of any birth defect, congenital 
abnormalities, or maternal and newborn complications, will be reported to the sponsor. Any 
complication of pregnancy during the study and any complication of pregnancy that the 
investigator becomes aware of after withdrawal from the study will be reported as an adverse 
event or serious adverse event, as appropriate.
If the pregnancy in the female patient participating in the study does not continue to term, 1 of 
the following actions will be taken:

For a spontaneous abortion, report as a serious adverse event.

For an elective abortion due to developmental anomalies, report as a serious adverse 
event.

For an elective abortion not due to developmental anomalies, report on the pregnancy 
form; do not report as an adverse event.
7.4.
Medication Error and Special Situations Related to the 
Investigational Medicinal Product
Any administration of IMP that is not in accordance with the study protocol should be reported
on the CRF either as a violation, if it meets the violation criteria specified in the protocol
(Section 11.1.2), or as a deviation, in the patients source documents, regardless of whether or not 
an adverse event occurs as a result. All instances of incorrect medication administration should 
be categorized on the CRF as “Non-Compliance with IMP”.
The following are types of medication errors and special situations:
2. Medication error: Any unintentional error in the prescribing, dispensing, or 
administration of a medicinal product while in the control of the healthcare professional, 
patient, or consumer.
3. Overdose: Administration of a quantity of a medicinal product given per administration 
or cumulatively which is above the maximum recommended dose according to the 
authorized product information. Clinical judgment should always be applied. Any dose of 
IMP (whether the test IMP or placebo), whether taken intentionally or unintentionally, in 
excess of that prescribed must be immediately reported to the sponsor.
4. Misuse: Situations where the IMP is intentionally and inappropriately used not in 
accordance with the authorized product information.
5. Abuse: Persistent or sporadic, intentional excessive use of IMP which is accompanied by 
harmful physical or psychological effects.

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
101
6. Off-label use: Situations where an IMP is intentionally used for a medical purpose not in 
accordance with the authorized product information.
7. Occupational exposure: Exposure to an IMP, as a result of one’s professional or non-
professional occupation.
8. Breastfeeding: Suspected adverse reactions that occur in infants following exposure to a 
medicinal product from breast milk.
7.5.
Clinical Laboratory Tests
All clinical laboratory test results outside of the reference range will be judged by the 
investigator as belonging to one of the following categories:

abnormal and not clinically significant

abnormal and clinically significant
The clinical significance of the laboratory values will be evaluated by the criteria described in 
the study laboratory manual and by the judgment of the investigator. A laboratory test result that 
is judged by the investigator as clinically significant will be recorded both on the source 
documentation and the CRF as an adverse event, and monitored as described in Section 7.1.2. An 
event may include a laboratory or diagnostic test abnormality (once confirmed by repeated
testing) that results in the withdrawal of the patient from the study, the temporary or permanent 
cessation of administration of IMP or medical treatment, or further diagnostic work-up.
Abnormal laboratory tests can be repeated without approval from the medical monitor. (Note: 
Abnormal laboratory or diagnostic test results at the screening visit that preclude a patient from 
entering the study or receiving IMP are not considered adverse events).
7.5.1.
Serum Chemistry, Hematology, and Urinalysis
Clinical laboratory tests (eg, serum chemistry, hematology and urinalysis) will be performed at 
the time points detailed in Table 1. Clinical laboratory tests will be performed using the central 
laboratory. Specific laboratory tests to be performed are provided in Table 5.

Other Clinical Laboratory Tests
7.5.2.1.
Human Chorionic Gonadotropin Tests
Human chorionic gonadotropin tests in urine or serum will be performed for all females who are 
postmenarchal or ≥12 years of age as detailed in Table 1 and if clinically indicated. Any female 
patient who becomes pregnant during the study will be withdrawn. Procedures for reporting the 
pregnancy are provided in Section 7.3.
7.5.2.2.
Urine Drug Screen
A UDS will be performed at the time points specified in Table 1. A positive result for any of the 
specified drugs or their metabolites, without medical explanation, will preclude the patient from 
enrollment or continued participation in the study.
7.6.
Vital Signs
Vital signs (BP, respiratory rate, body temperature, and pulse) will be measured at the time 
points detailed in Table 1. All vital signs results outside of the reference ranges will be judged by 
the investigator as belonging to one of the following categories:

abnormal and not clinically significant 

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
103

abnormal and clinically significant
Before BP and pulse are measured, the patient must rest in a supine or semi-erect/seated position 
and resting for at least 5 minutes. (The same position and arm should be used each time vital 
signs are measured for a given patient.)
For any abnormal vital sign finding, the measurement should be repeated as soon as possible. 
Any vital sign value that is judged by the investigator as clinically significant will be recorded 
both on the source documentation and the CRF as an adverse event, and monitored as described 
in Section 7.1.2.
On day 1 and weeks 4, 8, 28, and 54, orthostatic BP and pulse will be measured after the patient 
is in a standing position for at least 3 minutes.
7.7.
Electrocardiography
A 12-lead ECG will be recorded at the time points detailed in Table 1. All ECGs will be 
performed after at least 5 minutes rest in a supine or semi-supine position. A qualified physician 
at a central diagnostic center will be interpreting the ECG.
All ECG results outside of the reference ranges will be judged by the investigator as belonging to 
one of the following categories:

abnormal and not clinically significant 

abnormal and clinically significant
Any ECG finding that is judged by the investigator as clinically significant (except at the 
screening visit) will be considered an adverse event, recorded on the source documentation and 
in the CRF, and monitored as described in Section 7.1.2.
If a post-day 1 QTcF value >500 msec or change from baseline (Study TV50717-CNS-30046 or 
Study TV50717-CNS-30060) or day 1 (Study SD-809-C-17), as appropriate (see 
Section 9.7.2)>60 msec is found, the investigator should repeat the ECG assessment twice and 
compare the average of the 2 pre-treatment QTcF values (ie, the parent study baseline and 
screening values for patients rolling over from Study TV50717-CNS-30046 or Study TV50717-
CNS-30060; or the day 1 and screening values from the current study for patient[s] who 
completed Study SD-809-C-17) to the average of the 3 post-day 1 QTcF values. The IMP must 
be stopped for any confirmed post-day 1 QTcF value >500 msec or increase from baseline
(Study TV50717-CNS-30046 or Study TV50717-CNS-30060) or day 1 (Study SD-809-C-17) 
>60 msec.
7.8.
Physical Examinations
Physical examinations, including height and weight, general appearance, skin, head, eyes, ears, 
nose, throat, neck, lymph nodes, cardiovascular, respiratory, musculoskeletal, abdominal, and 
extremities will be performed at the time points detailed in Table 1. 
Weight must be measured with shoes and outerwear off.

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
104
Any physical examination finding that is judged by the investigator as clinically significant 
(except at the screening visit) will be considered an adverse event, recorded on the CRF, and 
monitored as described in Section 7.1.2.
7.9.
Assessment of Suicidality
TEV-50717 is considered to be central nervous system (CNS)-active. In addition, there have 
been some reports of suicidal ideation or behavior as reported in the product label when it has 
been given to some patients with certain conditions. The sponsor considers it important to 
monitor for such events before and during this clinical study.
Some CNS-active IMPs may be associated with an increased risk of suicidal ideation or behavior 
when given to some patients with certain conditions. Although this IMP or other similar 
medicinal products in this class have not been shown to be associated with an increased risk of 
suicidal thinking or behavior when given to this study population, the sponsor considers it 
important to monitor for such events before or during this clinical study.
The study population being administered TEV-50717 should be monitored appropriately and 
observed closely for suicidal ideation and behavior or any other unusual changes in behavior. 
Consideration should be given to discontinuing TEV-50717 in participants who experience signs 
of suicidal ideation or behavior, and detailed recommendations are provided in Section 7.2.2.
The day 1 assessment of suicidal ideation and behavior and treatment-emergent suicidal ideation 
and behavior will be assessed during the study using the Children’s C-SSRS described in 
Section 7.2.2.
Depression and Suicidality as an Adverse Event 
Families and caregivers of patients will be instructed to monitor patients for any changes in or 
new onset of depressive symptoms; unusual changes in mood, cognition, or behavior; or onset of 
and/or changes in suicidal ideation or behavior, and to report such symptoms immediately to the 
study investigator. Telephone contacts and clinic visits also allow opportunities for investigators 
to assess adverse events.
If a relevant change in status is identified, patients will be seen immediately for an unscheduled 
visit by the study investigator and discussed with the medical monitor. The patient will be 
referred for further psychiatric evaluation if there is any suspected suicidal ideation with any 
level of intent, suicidal behavior, or clinical findings suggesting that the patient may be 
dangerous to self or others, and/or experiencing depression. The investigator will record these 
symptoms as an adverse event of depression and/or suicidality. If it is determined by the 
investigator, after consultation with the medical monitor and the consulting psychiatrist, that 
exposure to the IMP may have contributed to the adverse event of depression or suicidality, IMP 
will be immediately discontinued and the patient will be terminated from the study. Follow up 
with a pediatric psychiatrist or licensed child and adolescent mental health clinician will be 
arranged.
In cases where it is determined that IMP did not contribute to the adverse event of depression or 
suicidality, the investigator will consult with the medical monitor and/or sponsor to determine 
whether the patient should continue in the study.
A reference sample is provided in Appendix E.

Neurological Examinations
Neurological examination, including mental status, cranial nerves, motor system (strength, tone, 
and posture), coordination, gait and balance, tendon reflexes, and sensation, will be performed at 
the time points detailed in Table 1. Any neurological examination finding that is judged by the 
investigator as a potentially clinically significant change (worsening) compared with the 
screening value will be considered an adverse event, recorded on the CRF, and monitored as 
described in Section 7.1.2. 
7.11.
Concomitant Medication or Treatment
Concomitant therapy or medication usage will be monitored throughout the study. 
Parents/patients will be instructed during the course of the study to notify the investigator if any 
new medication is prescribed/administered, including over-the-counter medications. Any 
prescribed/administered medication should be reviewed with the investigator.
Medications that are allowed, provided that conditions outlined in the table are met, are shown in 
Table 6. The tables for allowed and prohibited medications are not comprehensive and may not 
include all possible concomitant medications.
The medical monitor must be contacted if a patient is receiving (or has to begin or stop receiving 
during the study) a medication that is associated with QTc prolongation or that is a known strong
CYP inhibitor, or if there are any questions regarding any medication not listed in Appendix A. 
Prohibited medications that are associated with QTc prolongation are listed in Table 8, while 
prohibited antipsychotic drugs are listed in Table 7.
7.12.
Methods and Time Points of Assessing, Recording, and Analyzing 
Safety Data
All adverse events will be reviewed on a periodic basis by the CPP/medical monitor according to 
the safety monitoring plan (eg, scheduled safety reviews for TEV-50717) as preliminary safety 
databases become available.
Methods and time points of assessing safety data are discussed in Section 3.13. Procedures for 
recording safety data are discussed in Section 13.1, and methods of analyses are discussed in 
Section 9.7.2.
Information about the IDMC used for this study is provided in Section 3.7.

STATISTICS
This section describes the statistical analysis as foreseen at the time of planning the study. 
Changes, additions, and further details about the analyses will be described in the statistical 
analysis plan. After finalization of the statistical analysis plan, any additional analyses or 
changes to analyses that may be required will be fully disclosed in the clinical study report 
(CSR).
9.1.
Sample Size and Power Considerations
This study is safety-oriented in nature; therefore, no formal hypothesis testing is planned for 
Part A. Based on the number of patients in the previous studies, up to approximately 227 patients 
(approximately 1 patient from the Phase 1b Study SD-809-C-17, up to approximately 99 patients 
from the Phase 2/3 Study TV50717-CNS-30046, and up to approximately 127 patients from the 
Phase 3 Study TV50717-CNS-30060) are estimated to enroll.
All patients who complete Study TV50717-CNS-30060 or Study TV50717-CNS-30046 are 
eligible to participate in Study TV50717-CNS-30047. As the number of patients to be 
randomized in parent Study TV50717-CNS-30046 has increased, the number of patients 
anticipated to be randomized into Study TV50717-CNS-30047 has also increased. The rationale 
for the increased sample size in Study TV50717-CNS-30046 is provided that protocol.
For the randomized drug withdrawal period, 190 patients to be included in the analysis will 
provide approximately 90% power to detect a difference between TEV-50717-treated and 
placebo-treated patients assuming a difference in YGTSS TTS of 4.5 with a standard deviation 
of 9 using a two-sided test for difference at a significance level of 0.05.
9.2.
Analysis Sets
9.2.1.
Intent-to-Treat Analysis Set
The intent-to-treat (ITT) analysis set will include all enrolled patients, regardless of whether or 
not a patient took any IMP. Enrolled subjects who are not randomized will be summarized 
separately as “Not randomized,” and randomized subjects will be analyzed based on their 
randomized treatment. A patient is considered enrolled according to the status reported in the 
database. All efficacy analyses will be based on the ITT analysis set.
9.2.2.
Safety Analysis Set
The safety analysis set will include all patients who receive at least 1 dose of IMP. 
The safety analysis set will be used for all safety analyses.
9.2.3.
Randomized Withdrawal ITT Population
The Randomized Withdrawal ITT (RWITT) Population will include all patients enrolled in the 
randomized drug withdrawal period of the study.

Uncontrolled Study–Tourette Syndrome

108
9.2.4.
Randomized Withdrawal Safety Population
The Randomized Withdrawal Safety (RWSAF) Population will include all patients enrolled in 
the randomized drug withdrawal period who are administered any study drug. All summaries of 
safety measures in the randomized withdrawal period will be summarized descriptively in the 
RWSAF Population.
9.2.5.
Randomized Withdrawal Modified Intent-to-Treat Population
The Randomized Withdrawal Modified Intent-to-Treat (RWmITT) Population will include all 
patients enrolled in the randomized drug withdrawal period who receive study drug and have a 
YGTSS TTS at both the randomized drug withdrawal week 28 visit and the week 30 visit.
Efficacy measures in the randomized drug withdrawal period will be analyzed as described in 
Section 9.5.3.1.
9.2.6.
Responder Randomized Withdrawal Modified Intent-to-Treat Population
The Responder Randomized Withdrawal mITT (RRWmITT) Population will include all patients 
enrolled in the randomized drug withdrawal period who receive study drug and have a YGTSS 
TTS at both the week 28 visit and the week 30 visit and a ≥25% reduction in the TTS from 
baseline in the parent protocol to week 28. Efficacy measures in the randomized drug withdrawal 
period will be analyzed as described in Section 9.5.3.1. 
9.3.
Data Handling Conventions
For all variables, only the observed data from the patients will be used in the statistical analyses.
9.4.
Study Population
The ITT analysis set (see Section 9.2.1) will be used for all open-label efficacy summaries and 
analyses unless otherwise noted. The safety analyses set will be used for all safety summaries. 
Summaries will be presented for all patients.
The RRWmITT or RWmITT analysis set (see Section 9.2.5) will be used for all randomized 
withdrawal efficacy summaries and analyses unless otherwise noted. The RWSAF analysis set 
will be used for all randomized-withdrawal safety summaries.
9.4.1.
Patient Disposition
Data from patients who are enrolled, patients enrolled but not treated (and the reason), patients in 
the ITT, safety, and other analysis sets, patients who enter the randomized drug withdrawal 
period, patients who complete the randomized drug withdrawal period, patients who complete 
the study, and patients who withdraw from the study will be summarized using descriptive 
statistics. Data from patients who withdraw from the study will also be summarized by reason for 
withdrawal using descriptive statistics.
9.4.2.
Demographic and Baseline Characteristics
Patient demographic and baseline characteristics (day 1), including medical history, prior 
medications and treatments, and ECG findings, will be summarized using descriptive statistics
and will be analyzed by age group. For continuous variables, descriptive statistics (number [n],

Efficacy Analysis
No formal inferential statistics will be applied to the efficacy endpoints in Part A; however, 
inferential statistics will be applied to the efficacy endpoint in Part B (see Section 9.5.1).
9.5.1.
Efficacy Endpoints
The following efficacy endpoints will be assessed in Part A: 

change in the TTS of the YGTSS from day 1 to each visit in which the scale is 
administered

change in the Tourette Syndrome-Clinical Global Impression (TS-CGI) score from 
day 1 to each visit in which the scale is administered

change in the Tourette Syndrome-Patient Global Impression of Impact (TS-PGII) 
score from day 1 to each visit in which the scale is administered

change in the Child and Adolescent Gilles de la Tourette Syndrome – Quality of Life 
(C&A-GTS-QOL) activities of daily living (ADL) subscale score from day 1 to each 
visit in which the scale is administered
The following efficacy endpoint will be assessed in Part B: 

change in the TTS of the YGTSS from week 28 to week 30, with the primary 
analyses and sensitivity testing done as described in Section 9.5.3.1

Planned Method of Analysis
The ITT analysis set (see Section 9.2.1) will be used for all efficacy analyses in Part A. 
Summaries will be presented for all patients.
9.5.3.1.
Efficacy Analysis for the Randomized Drug Withdrawal Period
For the randomized drug withdrawal portion of the study, an analysis of covariance model will 
be used as the primary analysis model with the change from randomized-withdrawal week 28 to 
week 30 in YGTSS TTS as the dependent variable, and treatment group, randomized-withdrawal 
week 28 TTS, and age group at baseline as covariates. The least squares mean of the change in 
TTS from week 28 to week 30 will be compared (the active treatment arm and placebo arm) 
using a 2-sided test at the alpha=0.05 level of significance.
The primary analysis will be in the RRWmITT population (see Section 9.2.6). In addition, 
sensitivity testing will be done using the same model in the RWmITT population and in a 
subpopulation of the RRWmITT who had a ≥35% reduction in the TTS from baseline in the 
parent protocol to week 28.
9.6.
Multiple Comparisons and Multiplicity
This does not apply to this study.
9.7.

In addition to routine monitoring of adverse events, clinical laboratory parameters, 12-lead 
ECGs, and safety scales, an IDMC will monitor safety during the conduct of the study.
9.7.2.
Safety Analysis
All adverse events will be coded using the Medical Dictionary for Regulatory Activities. Each 
patient will be counted only once in each preferred term or system organ class category for the 
analyses of safety. Summaries will be presented for all adverse events (overall and by severity), 
adverse events determined by the investigator to be related to IMP (ie, reasonable possibility [see 
Section 7.1.4] defined as related or with missing relationship) (overall and by severity), serious 
adverse events, and adverse events causing withdrawal from the study. Patient listings of serious 
adverse events and adverse events leading to withdrawal will be presented.
Changes in laboratory and vital signs measurement data will be summarized descriptively. 
The use of concomitant medications will be summarized by therapeutic class using descriptive 
statistics. Concomitant medications will include all medications taken while the patient is treated 
with IMP.
Observed values in ECG parameters will be summarized, and counts and percentages of 
abnormal findings will be presented. Changes from parent study baseline (for patients rolling 
over from Study TV50717-CNS-30046 or Study TV50717-CNS-30060) or from day 1 (for 
patient[s] rolling over from Study SD-809-C-17) in ECG parameters will be summarized 
descriptively. In addition, the number and percentage of patients with on-treatment QTcF values 
>450, >480, or >500 msec and change from baseline (Study TV50717-CNS-30046 or Study 
TV50717-CNS-30060) or day 1 (Study SD-809-C-17) >30 or >60 msec will be presented.
Observed values in the C-SSRS and observed values and changes from baseline in the CDI-2 
(Parent and Self-Report Profiles) will be presented for all patients.
If any patient dies during the study, a listing of deaths will be provided, and all relevant 
information will be discussed in the patient narrative included in the CSR.
9.8.
Tolerability Variables and Analysis
Tolerability was not specifically defined.
9.9.
Planned Interim Analysis
When approximately 100 patients have completed the 28-week clinic visit, an interim analysis, 
including data from day 1 and up to week 28 visit only, will be conducted to provide descriptive, 
long-term safety and efficacy data to be used in regulatory submissions. To maintain data 
integrity of Study TV50717-CNS-30047, only a limited number of personnel who do not have 
contact with the sites will have access to this interim data in preparation for the regulatory filing. 

Uncontrolled Study–Tourette Syndrome

DIRECT ACCESS TO SOURCE DATA AND DOCUMENTS
The medical experts, study monitors, auditors, IEC/IRB, and inspectors from competent 
authority (or their agents) will be given direct access to source data and documents (eg, medical 
charts/records, laboratory test results, printouts, videotapes) for source data verification, provided 
that patient confidentiality is maintained in accordance with national and local requirements.
The investigator must maintain the original records (ie, source documents) of each patient’s data 
at all times. Examples of source documents are hospital records, office visit records, examining 
physician’s finding or notes, consultant’s written opinion or notes, laboratory reports, drug 
inventory, IMP label records, diary data, protocol-required worksheets, and CRFs that are used 
as the source (see Section 3.12).
The investigator will maintain a confidential patient identification list that allows the 
unambiguous identification of each patient. All study-related documents must be kept until 
notification by the sponsor.

QUALITY CONTROL AND QUALITY ASSURANCE
11.1.
Protocol Amendments and Protocol Deviations and Violations
11.1.1.
Protocol Amendments
No changes from the final approved (signed) protocol will be initiated without the prior written 
approval or favorable opinion of a written amendment by the IEC/IRB and national and local 
competent authorities, as applicable, except when necessary to address immediate safety 
concerns to the patients or when the change involves only nonsubstantial logistics or 
administration. The principal investigator at each investigational center, the coordinating 
investigator (if applicable), and the sponsor will sign the protocol amendment.
11.1.2.
Protocol Violations
Any deviation from the protocol that affects, to a significant degree, (a) the safety, physical, or 
mental integrity of the patients of the study and/or (b) the scientific value of the study will be 
considered a protocol violation. Protocol violations may include non-adherence on the part of the 
patient, the investigator, or the sponsor to protocol-specific inclusion and exclusion criteria, 
primary objective variable criteria, or GCP guidelines; noncompliance to the administration of 
IMP; use of prohibited medications. Protocol violations will be identified and recorded by 
investigational center personnel in a log or as part of the CRF. All protocol violations will be 
reported to the responsible IEC/IRB, as required.
When a protocol violation is reported, the sponsor will determine whether to discontinue the 
patient from the study or permit the patient to continue in the study, with documented approval 
from the medical expert. The decision will be based on ensuring the safety of the patient and 
preserving the integrity of the study.
Changes in the inclusion and exclusion criteria of the protocol are not prospectively granted by 
the sponsor. If investigational center personnel learn that a patient who did not meet protocol 
inclusion and exclusion criteria was entered in a study, they must immediately inform the 
sponsor of the protocol violation. If such patient has already completed the study or has 
withdrawn early, no action will be taken but the violation will be recorded.
11.2.
Information to Study Personnel
The investigator is responsible for giving information about the study to all personnel members 
involved in the study or in any element of patient management, both before starting the study and 
during the course of the study (eg, when new personnel become involved). The investigator must 
ensure that all study personnel are qualified by education, experience, and training to perform 
their specific task. These study personnel members must be listed on the investigational center 
authorization form, which includes a clear description of each personnel member’s 
responsibilities. This list must be updated throughout the study, as necessary.
The study monitor is responsible for explaining the protocol to all study personnel, including the 
investigator, and for ensuring they comply with the protocol. Additional information will be 

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04
Study TV50717-CNS-30047
115
made available during the study when new personnel members become involved in the study and 
as otherwise agreed upon with either the investigator or the study monitor.
11.3.
Study Monitoring
To ensure compliance with GCP guidelines, the study monitor or representative is responsible 
for ensuring that patients have signed the informed consent form and the study is conducted 
according to applicable SOPs, the protocol, and other written instructions and regulatory 
guidelines.
The study monitor is the primary association between the sponsor and the investigator. The main 
responsibilities of the study monitor are to visit the investigator before, during, and after the 
study to ensure adherence to the protocol; that all data are correctly and completely recorded and 
reported; and that informed consent/assent, depending on the child’s age, as appropriate, is 
obtained and recorded for all patients before they participate in the study and when changes to 
the consent form are warranted, in accordance with IEC/IRB approvals.
The study monitor will contact the investigator and visit the investigational center at regular 
intervals throughout the study. The study monitor will be permitted to check and verify the 
various records (CRFs and other pertinent source data records, including specific electronic 
source document [see Section 3.12]) relating to the study to verify adherence to the protocol and 
to ensure the completeness, consistency, and accuracy of the data being recorded. If electronic 
CRFs are used for the study, the study monitor will indicate verification by electronically 
applying source document verification flags to the CRF and will ensure that all required 
electronic signatures are being implemented accordingly.
As part of the supervision of study progress, other sponsor personnel may, on request, 
accompany the study monitor on visits to the investigational center. The investigator and 
assisting personnel must agree to cooperate with the study monitor to resolve any problems, 
errors, or possible misunderstandings concerning the findings detected in the course of these 
monitoring visits or provided in follow-up written communication.
11.4.
Clinical Product Complaints
A clinical product complaint is defined as a problem or potential problem with the physical 
quality or characteristics of clinical drug supplies or clinical device supplies used in a clinical 
research study sponsored by Teva. Examples of a product complaint include but are not limited 
to:

suspected contamination

questionable stability (eg, color change, flaking, crumbling, etc)

defective components

missing or extra units (eg, primary container is received at the investigational center 
with more or less than the designated number of units inside)

Each investigational center will be responsible for reporting a possible clinical product complaint 
by completing the product complaint form provided by Teva and emailing it to 
clinical.productcomplaints@tevapharm.com within 48 hours of becoming aware of the issue.
For complaints involving a device or other retrievable item, it is required that the device (or 
item) be sent back to the sponsor for investigative testing whenever possible. For complaints 
involving a drug product, all relevant samples (eg, the remainder of the patient’s drug supply) 
should be sent back to the sponsor for investigative testing whenever possible.
11.4.1.
Product Complaint Information Needed from the Investigational Center
In the event that the product complaint form cannot be completed, the investigator will obtain the 
following information, as available:

investigational center number and principal investigator name

name, phone number, and address of the source of the complaint

clinical protocol number

patient identifier (patient study number) and corresponding visit numbers, if 
applicable

product name and strength for open-label studies

patient number, bottle, and kit numbers (if applicable) for double-blind or open-label 
studies

product available for return Yes/No


Note: Reporting a product complaint must not be delayed even if not all the required information 
can be obtained immediately. Known information must be reported immediately. The sponsor 
will collaborate with the investigator to obtain any outstanding information.
11.4.2.
Handling of Investigational Medicinal Product at the Investigational Center
The investigator is responsible for retaining the product in question in a location separate from 
the investigator’s clinical study supplies. The sponsor may request that the investigator return the
product for further evaluation and/or analysis. If this is necessary, the clinical study monitor or 
designee will provide the information needed for returning the IMP.
If it is determined that the investigational center must return all IMP, the sponsor will provide the 
information needed to handle the return.

Adverse Events or Serious Adverse Events Associated with a Product Complaint
If there is an adverse event or serious adverse event due to product complaint, the protocol 
should be followed for recording and reporting (Section 7.1.2 and Section 7.1.5.3, respectively).
11.4.4.
Documenting a Product Complaint
The investigator will record in the source documentation a description of the product complaint,
and any actions taken to resolve the complaint and to preserve the safety of the patient. Once the 
complaint has been investigated by the sponsor and the investigator, if necessary, an event
closure letter may be sent to the investigational center where the complaint originated or to all 
investigational centers using the product.
11.5.
Audit and Inspection
The sponsor may audit the investigational center to evaluate study conduct and compliance with 
protocols, SOPs, GCP guidelines, and applicable regulatory requirements. The sponsor’s Global 
Clinical Quality Assurance, independent of Global Clinical Development, is responsible for 
determining the need for (and timing of) an investigational center audit.
The investigator must accept that competent authorities and sponsor representatives may conduct 
inspections and audits to verify compliance with GCP guidelines.

ETHICS
Details of compliance with regulatory requirements and applicable laws are provided in 
Section 1.6.
12.1.
Informed Consent/Assent
The investigator, or a qualified person designated by the investigator, should fully inform the 
patient and parent/legally acceptable representative of all pertinent aspects of the study, 
including the written information approved by the IEC/IRB. All written and oral information 
about the study will be provided in a language as nontechnical as practical to be understood by 
the parent/legally acceptable representative and the patient. The patient and parent/legally 
acceptable representative should be given ample time and opportunity to inquire about details of 
the study and to decide whether or not to participate in the study. The above should be detailed in 
the source documents.
A personally signed and dated informed consent form will be obtained from parent/legally 
acceptable representative, and a signed and dated assent, depending on the child’s age, as 
appropriate, will be obtained from each patient (if the patient is able) before any study-specific 
procedures or assessments are done and after the aims, methods, anticipated benefits, and 
potential hazards are explained; according to national and local IEC/IRB requirements. The 
forms will be signed and dated also by the person who conducted the informed consent 
discussion. The investigator will keep the original informed consent/assent forms, depending on 
the child’s age, as appropriate, and copies will be given to the patients. It will also be explained 
to the patients (and parent/legally acceptable representative) that they are free to refuse 
participation in the study and free to withdraw from the study at any time without prejudice to 
future treatment. Any patient that turns 18 years of age during the course of Study TV50717-
CNS-30047 will need to be re-consented as an adult.
For patients rolling over from Study TV50717-CNS-30046 or Study TV50717-CNS-30060, 
informed consent/assent, as appropriate, may be obtained prior to the day 1 visit, up to 4 weeks 
in advance of open-label study participation.
12.2.
Competent Authorities and Independent Ethics 
Committees/Institutional Review Boards
Before this study starts, the protocol will be submitted to the national and local competent 
authority and to each IEC/IRB for review. As required, the study will not start at a given 
investigational center before the IEC/IRB and competent authority (where applicable) for the
investigational center give written approval or a favorable opinion.
12.3.
Confidentiality Regarding Study Patients
The investigator must ensure that the privacy of the patients, including their identity and all 
personal medical information, will be maintained at all times. In CRFs and other documents or 
image material submitted to the sponsor, patients will be identified not by their names, but by an 
identification number.

DATA HANDLING, DATA QUALITY CONTROL, AND RECORD 
KEEPING
13.1.
Data Collection
Data will be collected using CRFs that are specifically designed for this study. The data collected 
on the CRFs will be captured in a clinical data management system (CDMS) that meets the 
technical requirements described in 21CFR Part 11. The CDMS will be fully validated to ensure 
that it meets the scientific, regulatory, and logistical requirements of the study before it is used to 
capture data from this study. Before using the CDMS, all users will receive training on the 
system and study-specific training. After they are trained, users will be provided with individual 
system access rights.
Data will be collected at the investigational center by appropriately designated and trained 
personnel, and CRFs must be completed for each patient who provided informed consent/assent. 
Patient identity should not be discernible from the data provided on the CRF. Data will be 
verified by the study monitor using the data source, and reviewed for consistency by Data 
Management using both automated logical checks and manual review. All data collected will be 
approved by the investigator at the investigational center. This approval acknowledges the 
investigator’s review and acceptance of the data as being complete and accurate.
If data are processed from other sources (eg, central laboratory, bioanalytical laboratory, central 
ECG center, diary data, electronic patient-reported outcome [ePRO] Tablet), the results will be 
sent to the investigational center, where they will be retained but not entered in the CRF, unless 
otherwise specified in the protocol. These data may also be sent electronically to the sponsor (or 
organization performing data management) for direct entry in the clinical database. Laboratory 
test results will not be entered in the CRF unless otherwise specified in the protocol. All data 
from other sources will be available to the investigators.
For patients who enter a study but do not meet entry criteria, at a minimum, data for screening
failure reason, demography, and adverse events from the time of informed consent/assent will be 
entered in the CRF.
13.2.
Data Quality Control
Data Management is responsible for the accuracy, quality, completeness, and internal 
consistency of the data from this study. Data handling, including data quality control, will 
comply with international regulatory guidelines, including ICH GCP guidelines. Data 
management and control processes specific to this study, along with all steps and actions taken 
regarding data management and data quality control, will be described in a data management 
plan.
CRFs received will be processed and reviewed for completeness, consistency, and the presence 
of mandatory values. Applicable terms will be coded according to the coding conventions for 
this study. Logical checks will be implemented to ensure data quality and accuracy. Any 
necessary changes will be made in the clinical database, and data review and validation 
procedures will be repeated as needed. Data from external sources will be compared with the 
information available in the CDMS. Discrepancies found will be queried.

Uncontrolled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 04

121
Data corrections in the CDMS will be made using the CDMS update function. The system 
requires a reason for each change and keeps a complete audit trail of the data values, dates, and 
times of modifications, and authorized electronic approvals of the changes.
At the conclusion of the study, the CDMS and all other study data will be locked to further 
additions or corrections. Locking the study data represents the acknowledgement that all data 
have been captured and confirmed as accurate.
13.3.

1.3.1.3. Toxicology
General and Reproductive Adult Toxicology: 
Oral administration of TEV-50717 in rats 
reduced body weight gain, increased mammary
hyperplasia, and produced estrous cycle
changes, all of which occurred with 
tetrabenazine at doses that produced similar 
systemic exposures to test articles and 
metabolites. Mammary and estrus effects are 
likely consequences of reduced central 
dopamine and subsequently increased 
prolactin, consistent with information in the 
Xenazine® (tetrabenazine) label. Oral 
administration of TEV-50717 in pregnant rats 
did not produce test article-related embryofetal 
toxicities, even at doses that led to reduced 
body weight gain in dams. Oral administration 
of metabolite M1 to pregnant rats from 
gestational days 6 to 17 produced no test 
article-related maternal or fetal toxicities.
Genetic Toxicology: TEV-50717 and its α-
HTBZ and β-HTBZ metabolites were negative 
in in vitro studies for mutagenicity (bacterial 
reverse mutation, or the Ames test) and for 
chromosomal structural aberrations in human 
peripheral blood lymphocytes. Oral doses of 
TEV-50717 arewere negative for inducing 
micronuclei in the bone marrow of treated 
mice. 
Juvenile Toxicology: The effects of 
TEV-50717 on juvenile development was 
assessed in male and female rats with oral 
dosing from weaning (postnatal day [PND] 
21) to PND 71, similar to human dosing from 
Year 2 through early adolescence and 
overlapping with TEV-50717 oral dosing in a 
general adult toxicology study. The effects of 
M1 were assessed in male and female juvenile 
rats from PND 25 to PND 70 with a recovery 
phase and postdosing reproductive 
assessment.
TEV-50717 produced no test-article-related 
effects on learning and memory functions, on 
histopathology assessments, on reproductive 
capacity (male and female fertility, estrus 
cyclicity), or on intrauterine survival of 
embyros from matings during recovery from

body weight gain and adverse clinical 
observation of tremors and in-cage 
hyperactivity were all noted in previous 
studies with adult rats; these effects have not 
predicted adult clinical intolerance to

1.4.1.1.Benefits of TEV50717
Although the efficacy of TEV 50717 in 
patients with TS has not yet been definitively 
established, preliminary efficacy data from 
Study SD 809 C 17 indicates a clinically 
meaningful reduction in motor and phonic tics 
observed by patients, parents, and treating 
clinicians. Furthermore, TEV 50717 has the 
same mechanism of action and 
indistinguishable pharmacology as 
tetrabenazine, an agent that is generally 
accepted among movement disorder experts to 
provide clinical benefit in this patient 
population (Jankovic and Kurlan 2011). Based 
on the nonclinical data discussed above and 
similar efficacy observed for tetrabenazine 
and TEV 50717 in studies of other indications

(see IB), TEV 50717 has the potential to offer 
effective treatment in children and adolescents 
with TS. 
1.4.1.2. Potential Risks of TEV 50717
The following information is based on clinical 
trial experience with TEV 50717 and the 
United States prescribing information for 
Xenazine (tetrabenazine):

TEV 50717 is contraindicated in patients 
who are actively suicidal, or in patients 
with untreated or inadequately treated 
depression.

TEV 50717 is contraindicated in patients 
with impaired hepatic function.

TEV 50717 is contraindicated in patients 
taking monoamine oxidase inhibitors 
(MAOIs). TEV 50717 should not be used 
in combination with an MAOI, or within a 
minimum of 14 days of discontinuing 
therapy with an MAOI.

TEV 50717 is contraindicated in patients 
taking reserpine. At least 21 days should 
elapse after stopping reserpine before 
starting TEV 50717.
Additional information regarding each 
potential issue may be found in the current IB.
1.4.2. Overall Risk and Benefit Assessment 
for This Study
There is a significant need to identify new 
treatments for TS that do not antagonize 
dopamine receptors, as these latter agents pose 
serious risks such as metabolic syndrome and 
TD, a movement disorder that is often 
irreversible. The results from 
Study SD 809 C 17 demonstrated meaningful 
efficacy in the context of good tolerability and 
no signal on safety scales, vital signs, 
laboratory parameters, or 12 lead 
electrocardiograms (ECGs). These findings 
are consistent with results in other study 
populations, such as HD, where the rates for 
TEV 50717 and placebo were similar for 
overall adverse events, neurologic and 
psychiatric adverse events, as well as dose 
reduction or dose suspension for adverse 
events (see IB for details).

After informed consent is obtained, patients 
rolling over from Study SD 809 C 17 who are 
screened will be assigned an 8 digit 
permanent identification number such that all 
patients from each investigational center are 
given consecutive identification numbers in 
successive order of inclusion. The first 2 digits 
of the screening number will be the number 
assigned to the country where the 
investigational center is located, the next 
3 digits will be the assigned number of the 
investigational center, and the last 3 digits will 
be assigned at the investigational center (eg, if 
the number assigned to the country is 01, the 
third patient screened at fifth investigational 
center would be given the number of

Not applicable
Highly effective birth control 
methods:
Highly effective birth control 
methods are methods that can 
achieve a failure rate of less than 
1% per year when used 
consistently and correctly are 
considered. Such methods 
include:
•
Combined estrogen and 
progestogen hormonal 
contraception (oral, intravaginal, 
transdermal) associated with 
inhibition of ovulation; these 
should be initiated at least 7 days 
(for IMPs without suspected 
teratogenicity/genotoxicity) and 1 
month (for IMPs potentially 
teratogenic/genotoxic) before the 
first dose of IMP.
•
Progestogen-only hormonal 
contraception (oral, injectable, 
implantable) associated with 
inhibition of ovulation; these 
should be initiated at least 7 days 
(for IMPs without suspected 
teratogenicity/genotoxicity) and 
1 month (for IMPs potentially 
teratogenic/genotoxic) before the 
first dose of IMP.
•
Intrauterine device (IUD) and 
intrauterine hormone-releasing 
system (IUS) need to be in place 
at least 2 months before 
screening.
•
Bilateral tubal occlusion
•
Vasectomized partner 
provided he is the sole sexual 
partner and has received medical 
assessment of the surgical 
process.

the preferred and usual lifestyle of 
the patient.
•
Periodic abstinence (eg, 
calendar, ovulation, 
symptothermal, post-ovulation 
methods), declaration of 
abstinence for the duration of a 
study, and withdrawal are not 
acceptable methods of 
contraception (according to 
Medicines and Healthcare 
Products Regulatory Agency, 
MHRA).

17.2.
Amendment 02 Dated 15 November 2017
The primary reason for this amendment is to incorporate a randomized drug withdrawal period, include and define CYP2D6 
impairment status, reorder the statistical testing methodology (ie, the inclusion of the TS-PGII assessment after TS-CGI and before the 
C&A-GTS-QOL ADL subscale), and include prohibited medications that are associated with QTc prolongation.
This amendment is considered to be substantial (ie, requires approval by Competent Authority, IEC, and/or IRB) by the sponsor’s 
Authorized Representative. Other nonsubstantial changes have been made to the protocol (and protocol synopsis, as appropriate). 
These changes are unlikely to affect the safety or rights (physical or mental integrity) of the patients in this clinical study or the 
scientific value of the clinical study.

3.1 General Design and Study Schematic Diagram
This is a 56-week, open-label, single-arm study that 
included a 2-week, double-blind, placebo-controlled, 
randomized drug withdrawal period to evaluate the 
safety of TEV-50717 in children and adolescents with 
tics associated with TS after they have successfully 
completed any of the parent studies (SD-809-C-17 
[Phase 1b], TV50717-CNS-30046 [Phase 2/3], or 
TV50717-CNS-30060 [Phase 3]). Patients rolling over 
from Study SD-809-C-17 will need to undergo all day 1
assessments. For patients rolling over from 
Study TV50717-CNS-30046 or Study TV50717 CNS-
30060, the week 13 visit (Study TV50717-CNS-30046) 
or the week 9 visit (Study TV50717-CNS-30060) will 
be the day 1 visit for Study TV50717-CNS-30047. If 
the patient does not wish to enroll in Study TV50717-

following the week 13 or week 9 visits, respectively.
For patients rolling over from Study SD-809-C-17, this 
study will consist of up to a 4-week screening period, a 
54 week, open label treatment period (including 7 (up 
to 31 days) and up to 52 weeks of titration and 47 
weeks of maintenance), and a 1 week washout period
treatment. Patients will have a follow-up telephone 
contact to evaluate safety 1 week after the end of the 
washout period (2 weeks after their last dose of IMP). 
Patients are expected to participate in this study for its 
entire duration, which is a minimum of 56 weeks. The 
end of study is defined as the date of the week 56 visit 
of the last participant.
Informed consent/assent and/or co-consent for patients 
14 years of age and older, as appropriate, will be 
obtained before any study procedures are performed. 
Patients may have informed consent/assent and/or co-
consent for patients 14 years of age and older, as 
appropriate, obtained prior to the baseline day 1 visit, 
up to 4 weeks in advance of open-label participation.
Any patient that turns 18 years of age during the course 
of Study TV50717-CNS-30047 will need to be re-

3.1.3 Titration Period
As patients from Study SD-809-C-17 will have been 
off study drug for several months at the time of 
enrollment, and since patients from Study TV50717-
CNS-30046 will have discontinued study drug (TEV-
50717 or placebo) for at least 1 week at completion of 
the parent study, all patients will undergo TEV-50717 
dose titration in this study. Patients will receive 6 mg of 
TEV-50717 with food on the evening of day 1. The 
titration scheme and maximum dose will be determined 
by body weight and use of strong cytochrome P450 
2D6 (CYP2D6) inhibitors, as shown in CYP2D6 
impairment status from the parent study. Patients will 
be classified as CYP2D6 impaired if they are receiving 
a strong CYP2D6 inhibitor or are a CYP2D6 poor 
metabolizer based on blinded assessment of CYP2D6 
genotype at baseline of the parent study. Patients who 
are CYP2D6 impaired will have a dose cap in the open 
label study, as shown in Table 2 and Table 3, 
respectively.
As patients from Study SD-809-C-17 will have been off IMP for

have discontinued IMP (TEV-50717 or placebo) for at least 1 
week at completion of the parent study, all patients will undergo 
TEV-50717 dose titration in this study. Patients will receive 6 mg 
of TEV-50717 with food on the evening of day 1. Tablets should 
be taken with food (eg, a snack) and should not be taken on an 
empty stomach. The titration scheme and maximum dose will be 
determined by body weight and CYP2D6 impairment status from 
the parent study. Patients will be classified as CYP2D6 impaired if 
they are receiving a strong CYP2D6 inhibitor or are a CYP2D6 
poor metabolizer based on blinded assessment of CYP2D6 
genotype at baseline of the parent study. Investigators will be

drug withdrawal period in which patients with TS may 
be eligible to participate after successful completion of 
any of the parent studies (SD-809-C-17 [Phase 1b], 
TV50717-CNS-30046 [Phase 2/3], or TV50717-

completed a parent study may be eligible to enroll in 
this study after they complete a 1-week washout period 
and the final evaluation in the parent study. For patients

The open-label study design (ie, no placebo or 
comparator) was selected to allow further evaluation 
and review long-term safety of TEV-50717 in this 
patient population. Patients will receive twice daily 
dosing for up to 54 weeks, with an initial 7-week 
titration period to allow for optimal dose selection. At 
week 28, patients will begin a blinded, randomized 
drug withdrawal period. The randomized drug 
withdrawal period will rigorously assess the long-term 
maintenance of effect. Patients will be randomized to 
their current dose of TEV-50717 or placebo for 2 
weeks. After completing the 2 weeks, patients will 
continue their same dose of TEV-50717 or be re titrated 
(patients receiving placebo only) for 3 weeks. At week 
34, patients will resume their maintenance dose. This is 
a classic ABA study design (ie, drug, placebo, drug) 
that allows for a more rigorous test of the intervention. 
In the traditional AB design, changes in symptoms 
(particularly in a long trial) could be attributed to other 
factors (eg, life changes, societal issues, and regression 
to the mean); however, an acute change demonstrated 
only in a placebo group among subjects that have been 
maintained for several months would reduce the 
likelihood of any other explanations for changes in 
symptoms.

This is an uncontrolled study with no other IMP.
Patients who receive TEV-50717 during the 
randomized drug withdrawal period will remain on 
blinded active IMP from week 30 to week 34; those 
assigned to placebo during the randomized drug 
withdrawal period will undergo blinded re-titration

dose from week 28. TEV-50717 tablets are available in 
the following dose strengths: 6, 9, 12, 15, and 18 mg, 
all of which are identical in size, shape, and color 
(white). The IMP will be supplied in 20-count bottles.

5.2 Restrictions
While patients receiving strong CYP2D6 inhibitors 
(paroxetine, fluoxetine, and bupropion) at baselineon 
day 1 may be enrolled into this study, the addition or 
removal of strong CYP2D6 inhibitors during treatment 
is discouraged as this would have an effect on exposure 
to active circulating drug. If the addition or removal of 
a strong CYP2D6 inhibitor is required from a clinical 
perspective, the medical monitor should be contacted 
so an appropriate change in IMP can be made. The 
addition of a strong CYP2D6 inhibitor is prohibited.

The clinical significance of the lablaboratory values 
will be evaluated by the criteria described in the study 
lablaboratory manual and by the judgment of the 
investigator. A laboratory test result that is judged by 
the investigator as clinically significant will be 
recorded both on the source documentation transcribed 
to and the CRF as an adverse event, and monitored as 
described in Section 7.1.2. An event may include a 
laboratory or diagnostic test abnormality (once 
confirmed by repeated testing) that results in the 
withdrawal of the patient from the study, the temporary 
or permanent cessation of treatment withadministration 
of IMP or medical treatment, or further diagnostic 
work-up. Abnormal laboratory tests can be repeated 
without approval from the medical monitor. (Note: 
Abnormal laboratory or diagnostic test results at the 
screening visit that preclude a patient from entering the 
study or receiving IMP are not considered adverse 
events).

7.9. Assessment of Suicidality
Not applicable
TEV-50717 is considered to be central nervous system (CNS)-
active. In addition, there have been some reports of suicidal 
ideation or behavior as reported in the product label when it has 
been given to some patients with certain conditions. The sponsor 
considers it important to monitor for such events before and during 
this clinical study.
Some CNS-active IMPs may be associated with an increased risk 
of suicidal ideation or behavior when given to some patients with 
certain conditions. Although this IMP or other similar medicinal 
products in this class have not been shown to be associated with an 
increased risk of suicidal thinking or behavior when given to this 
study population, the sponsor considers it important to monitor for 
such events before or during this clinical study.
The study population being administered TEV-50717 should be 
monitored appropriately and observed closely for suicidal ideation 
and behavior or any other unusual changes in behavior. 
Consideration should be given to discontinuing TEV-50717 in 
participants who experience signs of suicidal ideation or behavior.
Families and caregivers of participants being treated with TEV-
50717 should be instructed to monitor participants for the

Description of different birth control methods
Highly effective birth control methods:
Highly effective birth control methods are methods that 
can achieve a failure rate of less than 1% per year when 
used consistently and correctly are considered. Such 
methods include:
•
Combined estrogen and progestogen hormonal 
contraception (oral, intravaginal, transdermal) 
associated with inhibition of ovulation; these should be 
initiated at least 7 days (for IMPs without suspected 
teratogenicity/genotoxicity) and 1 month (for IMPs 
potentially teratogenic/genotoxic) before the first dose 
of IMP.
•
Progestogen-only hormonal contraception (oral,

•
Combined estrogen and progestogen hormonal contraception 
(oral, intravaginal, transdermal) associated with inhibition of 
ovulation; these should be initiated at least 1 month before the first 
dose of IMP.
•
Progestogen-only hormonal contraception (oral, injectable, 
implantable) associated with inhibition of ovulation; these should 
be initiated at least 1 month before the first dose of IMP.
•
Intrauterine device (IUD) and intrauterine hormone-releasing 
system (IUS) need to be in place at least 2 months before 
screening.
•
Bilateral tubal occlusion
•
Vasectomized partner provided he is the sole sexual partner 
and has received medical assessment of the surgical process.
•
Sexual abstinence is only considered a highly effective 
method if defined as refraining from heterosexual intercourse in 
the defined period. The reliability of sexual abstinence needs to be 
evaluated in relation to the duration of the clinical study and the 
preferred and usual lifestyle of the patient.
•
Periodic abstinence (eg, calendar, ovulation, symptothermal, 
post-ovulation methods), declaration of abstinence for the duration 
of a study, and withdrawal are not acceptable methods of 
contraception (according to Medicines and Healthcare Products 
Regulatory Agency, MHRA).
Unacceptable birth control methods:
Periodic abstinence (calendar, symptothermal, post-ovulation 
methods), withdrawal (coitus interruptus), spermicides only, and 
lactational amenorrhoea method (LAM) are not acceptable 
methods of contraception. Female condom and male condom 
should not be used together.

Female condom and male condom should not be used 
together.
Male contraception:
Male patients must always use a condom, except in 
cases of no genotoxicity; or no demonstrated or 
suspected human teratogenicity/fetotoxicity.
Vasectomy:
Use of contraceptive methods applies also to 
vasectomized men, because of the risk associated with 
transfer of a drug via seminal fluid.
Contraception for female partners of male study 
participants:
Female partners (who are not pregnant) of male study 
participants must use contraception for non pregnant 
WOCBP until the end of relevant systemic exposure in 
case of IMPs with genotoxicity or IMPs with no 
genotoxicity but demonstrated or suspected human
teratogenicity/fetotoxicity.
Pregnancy tests in females of childbearing potential:

Risk Safety Information. Shorter testing intervals are to 
be considered depending on drug dosing schedule.
2.
Consider additional pregnancy testing, but at least 
at the end of relevant systemic exposure, in case of 
possible human teratogenicity/fetotoxicity. This refers 
to IMPs, for which human data on pregnancies is 
limited or not available, there is no suspicion of human 
teratogenicity based on class effects or genotoxic 
potential, and nonclinical reproductive toxicity studies 
of relevance for early human pregnancy show positive 
findings that do not generate a strong suspicion of 
human teratogenicity/ fetotoxicity.
3.
For IMPs with unlikely risk of human 
teratogenicity/fetotoxicity, additional pregnancy testing 
is generally not necessary. This refers to IMPs for 
which assessment of the completed necessary 
nonclinical studies does not indicate teratogenicity/ 
fetotoxicity in early pregnancy and human data are not 
available or do not contradict these findings or there is 
already sufficient evidence for lack of risk based on 
human data.

This amendment is considered to be substantial (ie, requires approval by Competent Authority, IEC, and/or IRB) by the sponsor’s 
Authorized Representative. Other nonsubstantial changes have been made to the protocol (and protocol synopsis, as appropriate). 
These changes are unlikely to affect the safety or rights (physical or mental integrity) of the patients in this clinical study or the 
scientific value of the clinical study.
Note: In addition to the specific changes to the protocol that are listed in the table below, some minor typographical and grammatical 
changes were made for clarity and are not individually listed. Text that was moved but not otherwise changed is also not listed.

A blood sample for the measurement of IMP concentration 
should be collected, if possible, from each patient experiencing a 
serious adverse event or an adverse event leading to 
discontinuation of IMP at any time during the study. If study 
center personnel are unable to obtain a blood sample in a timely 
fashion, this should be discussed with the medical monitor to 
determine whether the sample still needs to be obtained.

placebo in order to check for return of symptoms. At the end of 
this period, patients who receive TEV 50717 during the 
randomized drug withdrawal period will return to the most 
recent dose of TEV 50717 and patients who received placebo 
during the randomized drug withdrawal period will begin 
titration post drug withdrawal. During the entire 5-week period, 
patients randomized to TEV-50717 will stay on their established 
maintenance dose of blinded active IMP. Patients who receive 
placebo during the randomized drug withdrawal period will 
undergo blinded retitration post-drug withdrawal. All patients 
will return to open-label dosing at week 34 (note that, because 
IMP is dispensed for 2-week periods, patients will use blinded 
bottles through the end of week 34; however, all patients will be 
known to be on active treatment at the start of week 34).

patient should continue taking that dose for the remainder of the 
titration period. and throughout maintenance dosing. If a patient 
experiences a “clinically significant” adverse event that is 
attributed to the IMP, the investigator will determine if a dose 
reduction or suspension is necessary. At the end of the titration 
period, the patient’s dose will be established for the maintenance 
period. If a patient experiences an adverse event during the 
maintenance period and the investigator believes a dose 
reduction is warranted, the dose may be reduced. Dose 
adjustments of TEV-50717 (upward or downward) may be made 
during the maintenance period, if necessary, but not more often 
than every 5 days and only in increments of 6 mg. During the 
maintenance period, if a patient’s weight shifts into a new 
category (see Table 2), and the investigator believes the patient 
is no longer at an optimal dose, the investigator may change the 
dose level.
IMP will be dispensed in the clinic. Patients should take their 
first dose in the evening on day 1 after their day 1 clinic visit.
Patients will receive sufficient doses to last until the next visit.

Amendment 04 Dated 22 May 2019
The primary reasons for this amendment are to address Regulatory Authority requirements; update the anticipated enrollment numbers 
to account for the increased sample size of Study TV50717-CNS-30046; include language on the addition of an interim analysis;
include additional nonclinical data observed in rat toxicology studies; further clarify procedures to be carried out during the screening 
and enrollment periods (eg, informed consent/assent stipulations); update requirements on drug storage, accountability, and security; 
update/clarify patient inclusion criteria, exclusion criteria, and withdrawal criteria; provide updates on allowed and prohibited 
medications; and include additional guidance for evaluation and management of suicidal ideation, suicidal behavior, and depression.
This amendment is considered to be substantial (ie, requires approval by Competent Authority, IEC, and/or IRB) by the sponsor’s 
Authorized Representative. Other nonsubstantial changes have been made to the protocol (and protocol synopsis, as appropriate). 
These changes are unlikely to affect the safety or rights (physical or mental integrity) of the patients in this clinical study or the 
scientific value of the clinical study.

1.3.1.3 Toxicology
The no-observed-adverse-effect level (NOAEL) for toxicities 
in juvenile rats is lower than that in adults; however, the total 
(α+β)-HTBZ exposure multiples or safety margins comparing 
rat to humans at the adult and juvenile age categories are 
similar. The potential for increased sensitivity to the effects of 
TEV-50717 in pediatric patients is mitigated by 2 factors. First, 
the effects of TEV-50717 on behavior and weight gain 
recovered with cessation of test article administration in the 
juvenile rat toxicology study. Second, the clinical significance 
of tremors and reduced body weight gain in rats dosed with 
TEV-50717 are unclear because these findings were not 
adverse events of note in adults or adolescent patients. While 
hypoactivity in rats has the potential to relate to clinical 
observations of somnolence, this adverse effect is controlled 
with dose reduction. In clinical comparison, the adverse event 
profile of tetrabenazine in adult patients is qualitatively similar 
to patients from approximately 22 months to 18 years of age 
(Jain et al 2006, Kenney et al 2007, Porta et al 2008).

9.1 Sample Size and Power Considerations
This study is safety-oriented in nature; therefore, no formal 
hypothesis testing is planned for Part A. Based on the number 
of patients in the previous studies, up to approximately 
212227 patients (approximately 1 patient from the Phase 1b 
Study SD-809-C-17, up to approximately 85 99 patients from 
the Phase 2/3 Study TV50717-CNS-30046, and up to 
approximately 126 127 patients from the Phase 3 
Study TV50717-CNS-30060) are estimated to enroll.

For the randomized drug withdrawal period, enrolling at least
190 patients to be included in the analysis will provide
approximately at least 90% power to detect a difference 
between TEV-50717-treated and placebo-treated patients 
assuming a difference in YGTSS TTS of 4.5 with a standard 
deviation of 9 assuming a type 1 error rate of 5%using a 
two-sided test for difference at a significance level of 0.05.
TV50717-CNS-30046 has increased, the number of 
patients anticipated to be randomized into Study

9.5.3.1 Efficacy Analysis for the Blinded, Randomized Drug Withdrawal PortionPeriod
For the randomized drug withdrawal portion of the study, an 
analysis of covariance model will be used as the primary 
analysis model with the change from randomized-withdrawal 
week 28 to week 30 in YGTSS TTS as the dependent variable, 
and treatment group, randomized-withdrawal week 28 TTS, 
and age group at baseline as covariates. The least squares mean 
of the change in TTS from week 28 to week 30 will be 
compared (the active treatment arm and placebo arm) using a 
2-sided test at the alpha=0.05 level of significance. In addition, 
actual values and changes in TTS will be summarized using 
descriptive statistics.
The primary analysesanalysis will be in the RRWmITT 
population; in (see Section 9.2.6). In addition, sensitivity 
testing will be done using the same analyses onmodel in the 
RWmITT population and in a subpopulation of the RRWmITT 
who had a ≥35% reduction in the TTS from baseline in the 
parent protocol to week 28.

APPENDIX L. FEMALES OF CHILDBEARING POTENTIAL AND 
BIRTH CONTROL METHODS 
Females of childbearing potential are defined as:

not surgically (documented hysterectomy, bilateral oophorectomy, or bilateral 
salpingectomy) or congenitally sterile

postmenarchal or ≥12 years of age 
Highly effective birth control methods:
Highly effective birth control methods are methods that can achieve a failure rate of less than 1% 
per year when used consistently and correctly are considered. Such methods include:

Combined estrogen and progestogen hormonal contraception (oral, intravaginal, 
transdermal) associated with inhibition of ovulation; these should be initiated at least 
1 month before the first dose of IMP.

Progestogen-only hormonal contraception (oral, injectable, implantable) associated 
with inhibition of ovulation; these should be initiated at least 1 month before the first 
dose of IMP.

Intrauterine device (IUD) and intrauterine hormone-releasing system (IUS) need to be 
in place at least 2 months before screening.

Bilateral tubal occlusion

Vasectomized partner provided he is the sole sexual partner and has received medical 
assessment of the surgical process.

Sexual abstinence is only considered a highly effective method if defined as 
refraining from heterosexual intercourse in the defined period. The reliability of 
sexual abstinence needs to be evaluated in relation to the duration of the clinical study 
and the preferred and usual lifestyle of the patient.

Periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods), 
declaration of abstinence for the duration of a study, and withdrawal are not 
acceptable methods of contraception (according to Medicines and Healthcare 
Products Regulatory Agency, MHRA).
Unacceptable birth control methods:
Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus 
interruptus), spermicides only, and lactational amenorrhoea method (LAM) are not acceptable 
methods of contraception. Female condom and male condom should not be used together.
