(β-HTBZ) metabolites of TEV-50717, and other metabolites (as needed), will be explored based on 
sparse sampling at week 12.
General Design and Methodology: 
This is a Phase 2/3, randomized, double-blind, placebo-controlled, parallel group study in which patients with tics 
associated with TS will be invited to participate. Patients who qualify for the study will be centrally randomized in a 
1:1 ratio (stratified by age at baseline [6 to 11 years, 12 to 16 years]) to receive either TEV-50717 or placebo. 
Throughout the study, patients will interact regularly with investigative site personnel, in clinic and by telephone, for 
the evaluation of safety, tic severity, and behavioral status (in clinic only). The target dose for each patient receiving 
TEV-50717 will be based on body weight and cytochrome P450 2D6 (CYP2D6) impairment status at baseline. 
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. CYP2D6 status will be used by 
Interactive Response Technology (IRT) for randomization into the study. The dose of IMP for each patient will be 
titrated to an optimal level followed by maintenance therapy at that dose. Investigators will be blinded to CYP 
status, with a dose cap for poor metabolizers prespecified by the IRT. The overall treatment period will be 12 weeks 
in duration, including a titration period of 7 weeks, a maintenance period of 5 weeks, followed by a washout period 
of 1 week
 
. For the YGTSS, input from the caregiver/adult is required. 
For both the TS-PGII and
, input from the caregiver/adult is permitted. For all other scales, for children 
13 years of age and under, interviews may be performed 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.

12
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.
Patients who complete the study may be eligible to begin participation in an open-label safety extension study 
TV50717-CNS-30047 after the end of the washout period. At the week 13 visit, patients may choose to enter 
Study TV50717-CNS-30047 (on that day), or they will have an additional week to make a decision and return for 
day 1. Patients not participating in Study TV50717-CNS-30047 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). 
Screening period (up to 31 days): 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, laboratory testing, and 12-lead ECG, along with 
rating scales to assess severity, frequency, and impairment of tics and 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 felt to be too 
burdensome for the patient. If the screening visit is divided into 2 visits, the blood sample should be obtained during 
the first of the 2 visits. Patients who have received comprehensive behavioral intervention for tics (CBIT) for TS or 
cognitive behavioral therapy (CBT) for obsessive-compulsive disorder (OCD) may participate in this study as long 
as therapy was completed at least 4 weeks prior to screening. Patients will return to the clinic on day 1 for baseline 
procedures and to re-confirm eligibility. Patients may be rescreened 1 time if there is a change in the status of the 
patient regarding eligibility for the study. (Note: Details of rescreening must be approved and documented by the 
medical monitor and/or Clinical Surveillance and Training [CST] team.)
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, especially at the baseline and week 12/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.
Titration period (7 weeks): Patients who remain eligible for participation in the study will be randomized at the 
baseline visit (day 1), and that evening (ie, after the study visit) will receive 6 mg of blinded IMP with food. 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 at baseline, as shown in the 
tables below. Patients and their caregiver/adult will interact weekly with the clinical research staff, either by 
telephone contact or clinic visit from week 1 through week 7 of the titration period, in order to evaluate safety and 
establish a dose of IMP that optimally reduces tics and is well tolerated (optimal dose). Safety evaluations during 
titration 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 criteria is met:

The investigator determines there has been a clinically meaningful reduction in tics as indicated by a 
sustained reduction in the TS-CGI.

The patient experiences a protocol-defined “clinically significant” adverse event (defined as an adverse 
event that is related to study medication 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 
at baseline.

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 on that dose (ie, the dose should not be increased further) for the remainder 
of the titration period and throughout maintenance dosing, unless there is a change in symptoms during the titration 
period. If a patient experiences a “clinically significant” adverse event attributable to the IMP, the investigator will 
determine if a dose reduction or suspension is necessary. 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 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. At the end of the titration period, the patient’s dose will be established for the 
maintenance period.
Maintenance period (5 weeks): Patients will continue to receive their maintenance dose over the next 5 weeks, 
although dose reductions for adverse events are allowed. Patients will return to the clinic at weeks 9 and 12 for 
assessments of safety and efficacy. At week 12, patients will undergo a complete evaluation, including physical and 
neurological examination, safety laboratory testing, and 12-lead ECG, CDI-2, and C-SSRS assessments, as well as 
the YGTSS, TS-CGI, TS-PGII, 
, 
, 
 and C&A-GTS-QOL. In addition, patients 
will undergo pharmacokinetic sampling at week 12.
Washout period and follow-up: All patients will discontinue IMP at the week 12 visit and will return 1 week later 
for evaluation of safety and tic reduction (week 13). Patients who complete the study may be eligible to begin 
participation in the open-label safety extension study, TV50717-CNS-30047, at that time. For this study, the 
follow-up period is defined as 1 week of washout for patients who will participate in the open-label safety extension 
study TV50717-CNS-30047 and 2 weeks after the last dose of IMP (1 week after the end of the washout period) for 
patients who will not roll over into the open-label safety extension study TV50717-CNS-30047. At the week 13 
visit, patients may choose to enter Study TV50717-CNS-30047 (on that day), or they will have an additional week 
to make a decision and return for day 1. Patients not participating in Study TV50717-CNS-30047 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 14]).
Prohibited drugs will remain the same during the washout period for patients who will participate in the open-label 
extension study TV50717-CNS-30047. 
Patients who will not participate in the extension study (Study TV50717-CNS-30047) may begin/resume tic therapy 
medication after the first week of the washout period. 
Method of Blinding and Randomization:
Patients will be randomly assigned to receive treatment with TEV-50717 or matching placebo in a 1:1 ratio using an 
IRT. Patients will be stratified by age at baseline (6 to 11 years, 12 to 16 years). Patients and investigators will 
remain blinded to treatment assignment during the study. In addition, the sponsor’s clinical personnel and all 
vendors (with the exception of the IRT vendor and the bioanalytical sample analysis 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. After unblinding of this study, the study site may remain blinded to patient treatment assignments until 
completion of the safety extension study TV50717-CNS-30047.
IMP Dose, Mode of Administration, and Administration Rate: 
IMP will be administered as oral tablets at a starting dose of 6 mg. Titration schemes based on body weight at 
baseline are shown in the tables below. The maximum daily dose is determined by body weight and CYP2D6 
impairment status at baseline (see the table below). Although dose adjustments can be made up to and including the 

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
14
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 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 in warranted, the dose may be reduced.
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 40-count blister packs. The placebo tablets and 
packaging will match those for TEV-50717. 
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 at the baseline visit, as shown in 
the tables below.

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. 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 must be notified.

During the titration period, the dose of IMP should be adjusted weekly according to the table below to 
identify a dose level that optimally reduces tics and is well tolerated. Investigators will be blinded to 
CYP status, with a dose cap for poor metabolizers prespecified by the IRT.

Pharmacokinetic Measures and Time Points:
Blood samples will be obtained for the measurement of plasma concentrations of TEV-50717 
(deutetrabenazine), α-HTBZ, β-HTBZ, and other metabolites, as needed. Blood sampling for pharmacokinetic 
analysis will be performed at the week 12 visit. Two samples will be collected. The first sample will be 
collected upon arrival at the clinic. The second sample will be collected 2 to 3 hours after the first 
pharmacokinetic sample collection. The time between samples should be maximized in order to provide the 
most useful information. Patients with early morning visits (ie, within 2 hours of their scheduled AM dosing) 
should take their dose in the clinic after the first pharmacokinetic sample is collected. 
Patients will be provided with a diary to provide critical information on dosing before the week 12 visit. The 
date and time of the last dose of study medication before the week 12 visit should be recorded in the diary by 
the patient or caregiver/adult. The site will document the date and time of the sample collection. Prior to the 
clinic visit on week 12, patients will be reminded to record the start time of their last meal and the time of their 
last dose in their diary
Plasma samples for both α-HTBZ and β-HTBZ metabolites will be pooled with previous data and incorporated 
into a population pharmacokinetic analysis. The population pharmacokinetic analysis will result in a final 
structural model that best describes the data. A covariate assessment will evaluate the relationship between 
potential covariates (ie, body weight, age, height, etc) and concentrations of α-HTBZ and β-HTBZ metabolites. 
The final population pharmacokinetic analysis will be included in a separate report. Exposure-response (eg, 
pharmacodynamic [PD] and/or safety endpoints) may be assessed if the appropriate data are available.
At the screening visit, a blood sample (3 mL) will be obtained for analysis of CYP2D6 genotype. The patient’s 
genotype for CYP2D6 will remain blinded during the conduct of the study.

Allowed and Disallowed Medications Before and During the Study: 
See Appendix A for details of allowed and disallowed medications. 
Statistical Considerations:
Sample Size Rationale: It is estimated that approximately 58 patients per arm will enable a power of at least 90% to 
detect a beneficial standardized effect of 63% or more when the TEV-50717 arm is compared to placebo (difference 
of 6.0 in the change from baseline to week 12 in TTS, assuming a standard deviation of 9.5 in each arm) in a 2-sided 
type I error rate of 5% after accounting for potential dropouts.
 
 
 
Analysis of Primary Endpoint: The primary efficacy endpoint for this study is the change in the TTS of the 
YGTSS from baseline to week 12. The primary analysis will be a mixed-model repeated-measures model with the 
change in the TTS as the dependent variable. The model will include fixed effects for treatment group, week
(5 levels: Weeks 2, 4, 6, 9, and 12), and the treatment group by week interaction. The baseline TTS, region, and age 
group at baseline will be included as covariates. The unstructured covariance matrix for repeated observations 
within patients will be used. The least squares means of the change in TTS from baseline at week 12 will be 
compared (the active treatment arm and the placebo arm) using a 2-sided test at the alpha=0.05 level of significance.
In addition, actual values and changes in the TTS from baseline to each visit will be summarized using descriptive 
statistics. 
Analysis of Key Secondary Endpoints: A hierarchical (fixed-sequence) testing approach will be used for the 
analysis of the primary and key secondary endpoints to maintain the experiment-wise type I error rate of 5%. If an 
endpoint is not statistically significant, confirmatory hypothesis testing will not be carried out on the remaining 
hypotheses, and remaining hypotheses will be considered exploratory rather than confirmatory. The change in the 
TS-CGI (1) and C&A-GTS-QOL ADL subscale (3) scores from baseline to week 12 will be summarized and 
analyzed in the same fashion as the primary analysis, with the exception that the baseline value of the given 
endpoint will be included as the covariate. TS-PGII (2) will be analyzed using a Cochran-Mantel-Haenszel row 
mean score test with a modified ridit score that controls for age group.
Exploratory Analyses:

Multiple Comparisons and Multiplicity: The hierarchical testing method will be used to maintain the 
experiment-wise type I error of 5% level for the primary and key secondary analyses. The primary efficacy endpoint 
will first be tested at the 5% type I error level. If the p-value of the primary analysis is ≤0.05, the secondary 
hypotheses will be tested in the order listed for the secondary endpoints until either an analysis produces a 
p-value >0.05 or all analyses result in a p-value ≤0.05.
Analysis of Pharmacokinetic Endpoint: Samples collected for pharmacokinetic analysis will be quantified for 
α-HTBZ and β-HTBZ active metabolites and will be analyzed using population pharmacokinetic techniques. 
Analysis methods will be detailed in a separate population pharmacokinetic analysis plan. Exploratory 
pharmacokinetic/PD analysis may be performed on PD/safety endpoints.
Safety Analyses: 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 
study treatment, serious adverse events, and adverse events causing withdrawal from the study. Summaries will be 
presented by treatment group and for all patients. Patient listings of serious adverse events and adverse events 
leading to withdrawal will be presented.
Observed values and changes from baseline 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. In addition, the number and percentage of patients with on-treatment QTcF values >450, >480, or 
>500 msec and change from baseline >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 C-SSRS and observed values and changes from baseline in the CDI-2 (Parent and Self-report
versions) will be presented by treatment group for all patients.

BACKGROUND INFORMATION
1.1.
Introduction 
Tourette syndrome (TS) is a neurodevelopmental disorder characterized by multiple motor and 
phonic tics that frequently co-occurs with a variety of behavioral and psychiatric problems 
(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, developed deutetrabenazine (referred to 

Placebo-Controlled Study–Tourette Syndrome

as TEV-50717, previously SD-809) that is eliminated more slowly than tetrabenazine. 
TEV-50717 has been shown to reduce plasma fluctuation and dosing frequency and thus can 
improve overall tolerability as compared to that of tetrabenazine. Data in patients receiving 
TEV-50717 for the treatment of chorea associated with Huntington 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 and for the treatment of chorea associated with TD on 
30 August 2017.
1.2.
Name and Description of IMP
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. TEV-50717 is provided for this study as 6-mg, 9-mg, 12-mg, 
15-mg, and 18-mg oral tablets, all of which are identical in size, shape, and color (white). The 
investigational medicinal product (IMP) will be supplied in 40-count blister packs.
A more detailed description of the product is given in Section 3.8. 
1.3.
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).
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 non-deuterated forms (Scherman et al 1988). 
Off-target binding occurs to a similar extent with deuterated and non-deuterated 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 (CNS) pharmacological effects. In particular, the adverse event of 
catalepsy, a known response in rats to drugs which reduce CNS dopamine concentrations 
(Fuenmayor and Vogt 1979), was similar in magnitude after TEV-50717 and tetrabenazine 
administration.

Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046

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, and 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 isozymes or transporters nor an inducer of CYP isozymes. M4, a major 
metabolite of tetrabenazine and TEV-50717 is neither an inhibitor of major CYP isozymes or 
transporters nor an inducer of CYP isozymes.
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 subsequent 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, 
clinical pathology, histopathology, ophthalmology, and performance in learning and memory 
tests).

Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
36
The NOAEL (no-observed-adverse-effect level) 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.

1.3.2.1.
Clinical Pharmacology Studies
Seven Phase 1 clinical pharmacology studies were conducted in healthy adult subjects. 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 the active metabolites of TEV-50717 based on the Phase 1 clinical 
pharmacology in healthy adult subjects were performed to support dose selection and 
pharmacokinetic characterization in a pediatric population. Subsequently, a further 
pharmacometric analysis of 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.

Pharmacometrics Analysis of TEV-50717 Active Metabolites to Support Dose 
Selection and Pharmacokinetic Characterization in a Pediatric Population
Population pharmacokinetic modeling of the TEV-50717 active metabolites -HTBZ and 
β-HTBZ has been performed throughout the clinical development program. Based on sequential 
pharmacokinetic sampling data obtained in healthy subjects in the Phase 1 program, a structural 
population pharmacokinetic model was developed to guide dose selection for HD patients with 
chorea (SD-809-CLN-076) and subsequently optimized to better describe the 
absorption/bioconversion profile of -HTBZ and β-HTBZ (Study SD-809-CLN-077). 

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
38
Employing the structural model defined in Study SD-809-CLN-077, sequential and sparse 
pharmacokinetic 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 provides the basis for the dosing recommendations in Section 5.1.

Known and Potential Risks and Benefits to Human Patients 
Additional information regarding benefits and risks to patients may be found in the current IB 
and in the United States prescribing information for AUSTEDO™(deutetrabenazine).
1.5.
Selection of Drugs and Dosages 
A detailed description of IMP administration is presented in Section 5.1.
1.5.1.
Justification for Dosage of Active Drug
The dose ranges to be evaluated in this study, based on body weight and CYP2D6 impairment 
status at baseline, were selected on the basis of the safety, preliminary efficacy, and population 
pharmacokinetic data generated from Study SD-809-C-17 (Table 2). In this study, TEV-50717 
up to 18 mg twice daily (36 mg/day) was well tolerated and demonstrated 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 twice daily), a level 
previously demonstrated to be efficacious, safe, and well tolerated in patients with 
HD-associated chorea. 
IMP will be titrated on a weekly basis for 7 weeks, based on investigator, patient, and 
parent/guardian assessments of tic reduction and adverse events. This dosing strategy is practical 
in a clinical setting and affords sufficient time between dose steps for efficacy and safety to be 
assessed. It is also consistent with the clinical application of tetrabenazine, another VMAT2 
inhibitor with accepted efficacy in this population. A 5-week maintenance period is sufficient for 
stable treatment to allow evaluation of safety and efficacy at the target dose.
1.5.2.
Justification for Use of Placebo
As TS is not a progressive neurological disorder, and available treatments are for symptomatic 
control, the use of placebo is justified in a short-term study where safety is carefully monitored. 

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
39
Moreover, a placebo control is ideal for characterizing the efficacy and safety of an experimental 
agent in a new study population.
1.6.
Compliance Statement
This study will be conducted in full accordance with the International Council for Harmonisation 
(ICH) Harmonised Tripartite Guideline for Good Clinical Practice (GCP) E6 and any applicable 
national and local laws and regulations (eg, Title 21 Code of Federal Regulations [21CFR] 
Parts 11, 50, 54, 56, 312, and 314, Directive 2001/20/EC of the European Parliament and of the 
Council on the approximation of the laws, regulations, and administrative provisions of the 
Member States relating to the implementation of GCP in the conduct of clinical studies on 
medicinal products for human use). Any episode of noncompliance will be documented.
The investigator is responsible for performing the clinical study in accordance with this protocol 
and the applicable GCP guidelines referenced above for collecting, recording, and reporting the 
data accurately and properly. Agreement of the investigator to conduct and administer this 
clinical study in accordance with the protocol will be documented in separate clinical study 
agreements with the sponsor and other forms as required by national competent authorities in the 
country where each investigational center is located.
The investigator is responsible for ensuring the privacy, health, and welfare of the patients during 
and after the clinical study and must ensure that trained personnel are immediately available in 
the event of a medical emergency. The investigator and the involved clinical study personnel 
must be familiar with the background and requirements of the study and with the properties of 
the IMP as described in the IB.
The principal investigator at each investigational center has the overall responsibility for the 
conduct and administration of the clinical study at that investigational center and for contacts 
with study management, with the Independent Ethics Committee/Institutional Review Board 
(IEC/IRB), and with competent authorities.
1.7.
Study Population and Justification
The population to be studied includes children and adolescents, 6 through 16 years of age, with 
TS. Per selection criteria, the participants’ tics need to be troublesome and cause distress or 
impairment based on the assessment of the patient, parent/guardian, and investigator. Based on 
these criteria, this is a study population in need of treatment.
1.8.
Location and Study Duration
This study is planned to be conducted in North America, Russia, and Europe, at approximately 
50 centers. It is expected to start in January 2018 and have a duration of approximately 
15 months. Additional centers will be added, if needed. Expected duration of the study may also 
be extended dependent on enrollment and other factors.

STUDY DESIGN
3.1.
General Design and Study Schema
3.1.1.
Overall Design and Screening Period
This is a Phase 2/3, randomized, double-blind, placebo-controlled, parallel group study in which 
patients with tics associated with TS will be invited to participate. Patients who qualify for the 
study will be centrally randomized in a 1:1 ratio (stratified by age at baseline [6 to 11 years, 12 to 
16 years]) to receive either TEV-50717 or placebo. Throughout the study, patients will interact 
regularly with investigative site personnel, in clinic and by telephone, for the evaluation of 
safety, tic severity, and behavioral status (in clinic only). The target dose for each patient 
receiving TEV-50717 will be based on body weight and CYP2D6 impairment status at baseline. 
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. CYP2D6 status will be used by Interactive Response Technology (IRT) for 
randomization into the study. The dose of IMP for each patient will be titrated to an optimal level 
followed by maintenance therapy at that dose. Investigators will be blinded to CYP status, with a 
dose cap for poor metabolizers prespecified by the IRT (Table 2). The overall treatment period 
will be 12 weeks in duration, including a titration period of 7 weeks, a maintenance period of 5 
weeks, followed by a washout period of 1 week.
 
 
 For the YGTSS, input from the caregiver/adult is 
required. For both the TS-PGII and 
 input from the caregiver/adult is permitted. For all 
other scales, for children 13 years of age and under, interviews may be performed 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. It should be 
noted that the CDI-2 has individual parent and child questionnaires.
Patients who complete the study may be eligible to begin participation in an open-label safety 
extension study (TV50717-CNS-30047) after the end of the washout period. At the week 13 
visit, patients may choose to enter Study TV50717-CNS-30047 (on that day), or they will have 
an additional week to make a decision and return for day 1. Patients not participating in 
Study TV50717-CNS-30047 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).
3.1.2.
Screening Period
The screening period in this study is up to 31 days. 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, laboratory testing, and 12-lead ECG, along with rating scales to 
assess severity, frequency, and impairment of tics and comorbid TS symptoms and behavioral 
status. 

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
43
At the discretion of the investigator, the screening visit may be divided into 2 visits if the visit 
length is felt to be too burdensome for the patient. If the screening visit is divided into 2 visits, 
the blood sample should be obtained during the first of the 2 visits. Patients who have received 
comprehensive behavioral intervention for tics (CBIT) for TS or cognitive behavioral therapy 
(CBT) for obsessive-compulsive disorder (OCD) may participate in this study as long as therapy 
was completed at least 4 weeks prior to screening. Patients will return to the clinic on day 1 to 
perform baseline procedures and to reconfirm eligibility. Patients may be rescreened 1 time if 
there is a change in the status of the patient regarding eligibility for the study. (Note: Details of 
rescreening must be approved and documented by the medical monitor and/or Clinical 
Surveillance and Training [CST] team.)
3.1.3.
Titration Period
During the titration period (7 weeks), patients who remain eligible for participation in the study 
will be randomized in a 1:1 ratio stratified by age (6 to 11 years, 12 to 16 years) at the baseline 
visit (day 1), and that evening (ie, after the study visit) will receive 6 mg of blinded IMP with 
food. 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 at baseline, as shown in Table 2. Patients and their caregiver/adult 
will interact weekly with the clinical research staff, either by telephone contact or clinic visit 
from week 1 through week 7 of the titration period, in order to evaluate safety and establish a 
dose of IMP that optimally reduces tics and is well tolerated (optimal dose). Safety evaluations 
during titration 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 criteria is met:

The investigator determines that there has been a clinically meaningful reduction in 
tics, as indicated by a sustained reduction in the TS-CGI

The patient experiences a protocol-defined “clinically significant” adverse event
(defined as an adverse event that is related to study medication 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 at baseline.
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 on that dose (ie, the dose should not be 
increased further) for the remainder of the titration period and throughout maintenance dosing, 
unless there is a change in symptoms during the titration period. If a patient experiences a 
“clinically significant” adverse event attributable to the IMP, the investigator will determine if a 
dose reduction or suspension is necessary. 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 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 

Placebo-Controlled Study–Tourette Syndrome

44
efficacy by the investigator, and information from rating scales. At the end of the titration period, 
the patient’s dose will be established for the maintenance period. 
3.1.4.
Maintenance Period
During the maintenance period (5 weeks), patients will continue to receive their maintenance 
dose, although dose reductions for adverse events are allowed. Patients will return to the clinic at 
weeks 9 and 12 for assessments of safety and efficacy. At week 12, 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. 
In addition, patients will undergo pharmacokinetic sampling at week 12. 
3.1.5.
Washout Period and Follow-up
All patients will discontinue IMP at the week 12 visit and will return 1 week later for evaluation 
of safety and tic reduction (week 13). Patients who complete the study may be eligible to begin 
participation in the open-label safety extension study TV50717-CNS-30047. For this study, the 
follow-up period is defined as 1 week of washout for patients who will participate in the 
open-label safety extension study TV50717-CNS-30047 and 2 weeks after the last dose of IMP 
(1 week after the end of the washout period) for patients who will not roll over into the 
open-label safety extension study TV50717-CNS-30047. At the week 13 visit, patients may 
choose to enter Study TV50717-CNS-30047 (on that day), or they will have an additional week 
to make a decision and return for day 1. Patients not participating in Study TV50717-CNS-30047 
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).
Prohibited drugs will remain the same during the washout period for patients who will participate 
in the open-label extension study TV50717-CNS-30047. 
Patients who will not participate in the extension study (Study TV50717-CNS-30047) may 
begin/resume tic therapy medication after the first week of the washout period.

3.2.
Justification for Study Design
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.
Preliminary efficacy and safety data for TEV-50717 as a treatment for TS have been generated in 
an open-label, Phase 1b pilot study (Study SD-809-C-17). Results of Study SD-809-C-17 
supported further development of TEV-50717 as a treatment of TS.
Consequently, the standard placebo-controlled, double-blind study design (TEV-50717 versus 
placebo in a 1:1 ratio) was chosen for the next study (ie, this Phase 2/3 study) to determine 
whether IMP treatment results in a statistically significant effect on tics in patients with TS.
The justification for the choice of the comparator (placebo) is provided in Section 1.5.2, the 
choice of dosage is discussed in Section 1.5.1, while the justifications for the choice of the 
population and the inclusion and exclusion criteria for the study are provided in Section 1.7 and 
Section 4.3, respectively.

Pharmacokinetic Measures and Time Points
Blood samples will be obtained for the measurement of plasma concentrations of TEV-50717 
(deutetrabenazine), α-HTBZ, β-HTBZ, and other metabolites, as needed. Blood sampling for 
pharmacokinetic analysis will be performed at the week 12 visit. Two samples will be collected. 
The first sample will be collected upon arrival at the clinic. The second sample will be collected 
2 to 3 hours after the first pharmacokinetic sample collection. The time between samples should 
be maximized in order to provide the most useful information.
A description of the pharmacokinetic measures is provided in Section 8.
3.6.
Randomization and Blinding
This is a randomized, double-blind, placebo-controlled study. Patients will be randomly assigned 
to receive treatment with TEV-50717 or matching placebo in a 1:1 ratio stratified by age at 
baseline (6 to 11 years, 12 to 16 years). Patients and investigators will remain blinded to 
treatment assignment during the study. 
Patients will be centrally randomly assigned to the treatment groups by means of a 
computer-generated randomization list after confirmation of all eligibility criteria. The creation 
of the randomization list will be under the responsibility and oversight of Syneos Health.
In addition, the sponsor’s clinical personnel and all vendors (with exception of the IRT vendor
and the bioanalytical sample analysis vendor) involved in the study will be blinded to the IMP 
identity until the database is locked for analysis and the treatment assignment revealed. After 
unblinding of this study, the study site may remain blinded to patient treatment assignments until 
completion of the safety extension study TV50717-CNS-30047.
The randomization list and treatment will be assigned to the relevant treatment groups through a 
qualified service provider (ie, via IRT). The generation of the medication list and management of 
the IRT system will be done by a qualified service provider under the oversight of Nuvelution TS 
Pharma.

The staff member at the investigational center who will dispense the IMP will not know the 
treatment given to each patient.
3.7.
Maintenance of Randomization and Blinding
3.7.1.
Randomization 
Patient randomization codes will be maintained in a secure location within Syneos Health, 
Biometrics. 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.
3.7.2.
Blinding/Unblinding
Pharmacokinetic data may be assessed during the study. For patients who have pharmacokinetic 
sample bioanalysis and/or data analysis conducted, the individuals responsible for sample 
bioanalysis and other responsible personnel will know who received IMP and who received 
placebo during the study (of those patients only). Personnel responsible for bioanalysis will be 
provided with the randomization code in order to facilitate the analysis. However, the personnel 
responsible for bioanalysis and pharmacokinetic data analysis will not have access to clinical 
safety and efficacy data, will not have any interaction with study personnel, and will provide 
concentration data to other personnel in a manner that will not identify individual patients (ie, a 
dummy patient identifier will be linked to an individual patient’s concentration data). 
For information about personnel who may be aware of treatment assignments, see Section 3.6. 
These individuals will not be involved in conduct of any study procedures or assessment of any 
adverse events.
In case of a serious adverse event or 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. Individual treatment 
codes, indicating the treatment randomization for each randomized patient, will be available to 
the investigator(s) and/or pharmacist(s) at the study center via the IRT system. If possible, the 
sponsor should be notified of the event prior to breaking of the code. If this is not possible, the 
sponsor should be notified immediately afterwards, and the patient’s drug code assignment 
should not be revealed. Breaking of the treatment code can always be performed by the site 
without prior approval by the sponsor.
When a blind is broken, the patient will be withdrawn from the study, and the event will be 
recorded onto the case report form (CRF). However, if a patient is unblinded by mistake, the 
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. Treatment assignment 
should not be recorded in any study documents or source document.
In blinded studies, for adverse events that are defined as: suspected unexpected serious adverse 
reactions (SUSARs) (ie, reasonable possibility; see Section 7.1.4), Global Patient Safety and 
Pharmacovigilance (GPSP) may independently request that the treatment code be revealed (on a 
case-by-case basis) to comply with regulatory requirements. The report will be provided in an 

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
49
unblinded manner for regulatory submission. If this occurs, blinding will be maintained for the 
investigator and for other personnel involved in the conduct, analysis, and reporting of the data.
3.7.3.
Independent Data Monitoring Committee
During the conduct of this study, an IDMC will review accumulating safety data on a regular 
basis to ensure the continuing safety of the study patients and review of 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 may 
be present, and information is provided and discussed in a blinded fashion. 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.
Drugs Used in the Study
3.8.1.
IMP
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. TEV-50717 tablets are available in the 
following 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 40-count blister packs. The placebo tablets and packaging 
will match those for TEV-50717. Each blister pack (40-count tablets per dose strength per blister 
pack) 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.

50
3.8.2.
Placebo 
Placebo tablets match TEV-50717 tablets. The packaging will be the same as described for
TEV-50717 above.
A more detailed description of administration procedures is given in Section 5.1.
3.9.
Drug Supply and Accountability
3.9.1.
Drug Storage and Security
The IMP (TEV-50717 and placebo) 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 and 
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
This study will consist of up to a 31-day screening period, a 12-week double-blind treatment 
period, and a 1-week washout period. Patients who complete the study may be eligible to begin 
participation in an open-label safety extension study TV50717-CNS-30047 after the end of the 
washout period. Patients not participating in Study TV50717-CNS-30047 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 
14 weeks. 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). The investigator and/or sponsor can withdraw a 

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
51
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). 
Please see Section 4.4 for the withdrawal criteria and procedures.
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
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), Section 7
(safety assessments), and Section 8 (pharmacokinetic and other assessments).

b Assessment to occur at the end of the study week.
c Patients will be provided with a diary to record critical information on dosing. The date and time of the last dose of study medication before the week 12 visit 
should be recorded in the diary by the patient or caregiver/adult. The site will document the date and time of the sample collection. Prior to the clinic visit on 
week 12, patients will be reminded to record the start time of their last meal and the time of their last dose in their diary.
d 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 14 (Section 3.13.4.2).
e This visit is a telephone contact for safety evaluation, required only for patients who will not roll over into the open-label safety extension study TV50717-
CNS-30047.
f The screening visit may be conducted over 2 separate visits at the discretion of the investigator.
g Dose adjustment will be made by the investigator after telephone contact with the patient and caregiver/adult to evaluate tic reduction and adverse events.
h 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).
i Orthostatic BP and pulse will be measured after patient is in a standing position for at least 3 minutes.
j Assessment to be completed at investigator’s discretion.
k All ECGs will be performed after at least 5 minutes rest in a supine or semi-supine position.
l Two samples will be collected. The first sample will be collected upon arrival at the clinic. The second sample will be collected 2 to 3 hours after the first 
pharmacokinetic sample collection. Patients with early morning visits (ie, within 2 hours of their scheduled AM dosing) should take their IMP dose in clinic 
after the first pharmacokinetic sample is collected.
m Patients with clinically significant laboratory abnormalities at week 12 will have those laboratory evaluations repeated at the week 13 visit.
n The patient’s genotype for CYP2D6 will be blinded during the conduct of the study. 
o For females who are postmenarchal or ≥12 years of age, a urine test will be administered at baseline and week 4, while a serum test will be administered at 
screening and week 12, and if clinically indicated.
p MINI Kid, (Children and Adolescents) modules to be used are: 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).
q For children 13 years of age and under, interviews may be performed 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.
r Children 6 years of age at baseline will not complete the Self-report version; the caregiver/adult will complete the Parent version.
s Input from the caregiver/adult is required.
t The YGTSS, TS-CGI, TS-PGII, and 
 questionnaires should be performed before any blood draws or ECG assessments.
u Perform assessment of “Severity Ratings” of the questionnaire. Inventory portions, ie, “Motor Tic Symptom Checklist” and “Phonic Tic Symptom Checklist” 
do not need to be performed.
v Perform the Severity Ratings of OCD symptoms (Questions 1 through 10) only. Checklist does not need to be performed.
w Contact IRT and dispense IMP and patient diary.
x IMP will be dispensed in the clinic; patients will receive doses for 2 weeks (current dose level and next dose level) to cover the telephone contacts. The site will 
determine titration (ie, starting the next dose) for the patient by telephone. See Table 2 for baseline weight-based dosing titration.

Procedures for Screening and Enrollment
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 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 
status of the patient regarding eligibility for the study. (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 baseline visit. The screening 
visit may be conducted over 2 separate visits at the discretion of the investigator. The following 
procedures will be performed at screening:

obtain written informed consent/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

review medical and psychiatric history

review demographics information

measure vital signs (pulse, BP, body temperature, and respiratory rate) 


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, especially at the baseline 
and week 12/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.
3.13.2.
Procedures Before IMP Treatment (Baseline/Day 1)
Patients who meet the inclusion/exclusion criteria at screening will continue to the baseline visit, 
when baseline evaluations will be conducted.
The following procedures will be performed at baseline:

conduct clinic visit

review eligibility (inclusion and exclusion) criteria

measure vital signs (orthostatic pulse and BP [after standing for at least 3 minutes], 
body temperature, and respiratory rate)

measure weight (Note: Weight must be measured with shoes and outerwear off)


Procedures During IMP Treatment
3.13.3.1.
Titration Period (Baseline/ Day 1 Through 7)
3.13.3.1.1. Telephone Contacts (Weeks 1, 3, 5, and 7)
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 blister packs 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 continue titration 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.

Dosing requirements for the week 12 visit must be followed to ensure appropriate 
pharmacokinetic sample collection. Patients with early morning visits (ie, within 2 hours of their 
scheduled AM dosing) should take their dose in clinic after the first pharmacokinetic sample is 
collected. The date and time of the last dose of study medication before the week 12 visit should 
be recorded in the diary by the patient or caregiver/adult. The site will document the date and 
time of the sample collection. Prior to the clinic visit on week 12, patients will be reminded to 
record the start time of their last meal and the time of their last dose in their diary. The following

All patients will discontinue IMP at the week 12 visit and will return 1 week later for evaluation 
of safety and tic reduction (week 13 visit; see Section 3.13.4.1). Patients who complete the study 
may be eligible to begin participation in an open-label safety extension study TV50717-CNS-
30047. Patients not participating in Study TV50717-CNS-30047 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 14 visit]; see Section 3.13.4.2). 
For patients who withdraw prematurely an early termination visit (see Section 3.13.3.2.2 for 
applicable procedures) 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 14 
(Section 3.13.4.2). Additional details for patients who withdraw prematurely from the study are 
described in Section 4.4. 
As appropriate, patients should be treated with standard of care following termination of the 
study.
Data from any efficacy evaluations performed after the specified time will not be collected on 
the CRF; in the event, however, that such data are collected, these data will not be analyzed. 
Patients with ongoing adverse events or clinically significant abnormal laboratory test results (as 
interpreted by the investigator) will be monitored as described in Section 4.4 and Section 7.1.2.

69
w. Patient has a DSM diagnosis based on the MINI Kid modules performed at screening 
that, in the opinion of the investigator, makes the patient unsuitable for the 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 (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
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 Sections 4.3 and 7.1.7). The investigator should repeat the ECG assessment twice 
and compare the average of the 2 pre-treatment QTcF values (baseline and screening) 
to the average of the 3 post-baseline QTcF values. The IMP must be stopped for any 
confirmed post-baseline QTcF value >500 msec or increase from baseline >60 msec.
g. when a blind is broken due to safety concerns (see Section 3.7.2). 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 3.7, 3.11, 3.13.4, 
5.4, and 7.1.7. 
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 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 3.13.3.2.2.

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
70
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). 
A patient who is enrolled but does not complete the treatment period will not be replaced.

TREATMENT OF PATIENTS
5.1.
Drugs Administered During the Study 
IMP (see Section 3.8) will be administered as oral tablets at a starting dose of 6 mg. Titration 
schemes based on body weight at baseline are shown in Table 2. The maximum daily dose is 
determined by body weight and CYP2D6 impairment status at baseline. 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 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.
IMP will be dispensed in the clinic. Patients will receive doses for 2 weeks at baseline, week 2, 
and week 4 visits (current dose level and next dose level) to cover the telephone contacts. At 
week 6 and week 9 visits, patients will receive doses for 3 weeks. 
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 at the baseline 
visit, as shown in Table 2.

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. 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 must be notified.

During the titration period, the dose of the IMP will be adjusted weekly according to 
Table 2 to identify a dose level that optimally reduces tics and is well tolerated. 
Investigators will be blinded to CYP status, with a dose cap for poor metabolizers 
prespecified by the IRT.
IMP will be packaged in blister packs and provided for patients to take at home (see Section 3.8).

b Patients will receive 6 mg on days 1 and 2, and 12 mg starting on day 3.
bid=twice a day; CYP=cytochrome P450; IMP=investigational medicinal product.
Note: CYP impaired patients are those patients who are receiving a strong CYP2D6 inhibitor or who are a CYP2D6 
poor metabolizer. The investigator, in consultation with the patient and caregiver/adult, will determine if a dose 
increase is warranted to achieve optimal tic reduction.
5.2.
Restrictions
Medications prohibited before and/or during the study are described in Section 5.3. 
While patients receiving strong CYP2D6 inhibitors such as paroxetine, fluoxetine, and 
bupropion at baseline 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 use of quinidine and terbinafine are prohibited (see Appendix A, Table 8). 
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.

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
73
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 Therapy or Medication
Any prior or concomitant therapy, medication, or procedure a patient has had within 3 months 
before 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. 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, 
including over-the-counter medications. Any prescribed 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 5.
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.
Prohibited medications that are associated with QTc prolongation are listed in Appendix A, 
Table 6, while prohibited antipsychotic drugs are listed in Appendix A, Table 7.
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.

74
5.5.
Dose Reduction and Temporary IMP 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.
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 significant, 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.
5.6.
Total Blood Volume
The total volume of blood to be collected for each patient in this study is approximately 35 mL, 
as detailed in Table 3.

ASSESSMENT OF EFFICACY
Site-administered efficacy scales include the YGTSS and the 
, and self-administered 
efficacy scales include the TS-PGII, 
 and C&A-GTS-QOL.
6.1.
Primary Efficacy Measure and Justification
The primary efficacy measure is the TTS of the YGTSS. 
The YGTSS is administered at screening; baseline; and weeks 2, 4, 6, 9, 12, and 13:

Complete assessment (Checklist and Severity Ratings) at screening, baseline, and 
weeks 4 and 12

Severity Ratings assessment only at weeks 2, 6, 9, and 13

Input from caregiver/adult is required for all patients irrespective of age.
The choice of YGTSS (specifically the TTS) as a primary efficacy measure is supported by its 
wide use in clinical practice for evaluation of symptoms associated with TS and its successful 
use in the Phase 1b study SD-809-C-17 (Section 1.3.2.2).
The YGTSS rating scale is a semi-structured clinician rating instrument that provides an 
evaluation of the number, frequency, intensity, complexity, and interference of motor and phonic 
tics (Leckman et al 1989). The items pertaining to the tic ratings are scored on 2 subscales:
Motor Tics and Vocal Tics. Behaviors are rated on a 6-point scale. The scale has a look-back 
period of 1 week. Additionally, the scale assesses the severity of tics, which includes overall 
impairment of the patient, and combines motor and visual tic information into a TTS score. A 
 can then be determined by combining the patient’s severity rating with the TTS.
A reference sample is provided in Appendix G.
6.2.
Key Secondary Efficacy and Exploratory Measures
6.2.1.
Tourette Syndrome–Clinical Global Impression
The TS-CGI is administered at baseline and at weeks 2, 4, 6, 9, 12, and 13. 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.
6.2.2.
Tourette Syndrome-Patient Global Impression of Impact
The TS-PGII is administered at baseline and weeks 2, 4, 6, 9, 12, and 13. 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 

Placebo-Controlled Study–Tourette Syndrome

change have face validity and have been shown to correlate with disability for a number of 
chronic conditions.
6.2.3.
 
 
 
 
 
6.2.4.
Child and Adolescent Gilles de la Tourette Syndrome-Quality of Life Scale
The C&A-GTS-QOL is administered at baseline, week 6, and week 12. 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&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 6 subscales (cognitive, coprophenomena, psychological, physical, obsessive-
compulsive, and ADL) 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). 
A reference sample is provided in Appendix K.

ASSESSMENT OF SAFETY 
In this study, safety will be assessed by qualified study personnel by evaluating the following: 
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 (Note: A condition recorded as pre-existing that 
is intermittently symptomatic [eg, headache] and that occurs during this study should 
be recorded as an adverse event.)

drug interactions

events occurring during diagnostic procedures or during the 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 study 
treatment are not considered adverse events.)

7.1.2.
Recording and Reporting 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. For this 
study, the follow-up period for recording of adverse events is defined as 1 week of washout for 
patients who will participate in the open-label safety extension study TV50717-CNS-30047 and
2 weeks after the last dose of IMP for patients who will not roll over into Study TV50717-CNS-
30047.
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; 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

Relationship of an Adverse Event to the IMP
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
An additional blood sample for the measurement of IMP concentration should be collected, if 
possible, from each patient experiencing a serious 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.
For recording of serious adverse events, the study period is defined for each patient as the time 
period from signature of the informed consent/assent form to the end of the follow-up period, as 
defined in Section 7.1.2. If the investigator becomes aware of serious adverse events occurring in 
a patient after the end of the follow-up period, the serious adverse events should be reported to 
the sponsor 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:

results in death

is a life-threatening adverse event (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

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 alkaline 
phosphatase [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.

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
83
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 GPSP will determine the expectedness for all serious adverse events.
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 of that patient 
has ended 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 GPSP.
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

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
84

concomitant medication (including doses, routes of administration, and regimens) and 
treatment of the event

pertinent laboratory or other diagnostic test data 

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 GPSP 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.
Blinding will be maintained for all study personnel. Therefore, in case of a SUSAR, only the 
LSO/Syneos Health will receive the unblinded report for regulatory submission; the others will 
receive a blinded report. 
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 regulatory authorities (and IEC/IRB, as 
appropriate), other action may be required, including the following: 

altering existing research by modifying the protocol

discontinuing or suspending the study

modifying the existing consent form and informing current study participants of new 
findings

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
85

modifying listings of expected toxicities to include adverse events newly identified as 
related to TEV-50717
7.1.6.
Protocol-Defined Adverse Events of Special Interest
No protocol-defined adverse events of special interest were identified for this study.
7.1.7.
Withdrawal Due to an Adverse Event
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. If a post-baseline QTcF 
value >500 msec or change from baseline >60 msec is found, the investigator should repeat the 
ECG assessment twice and compare the average of the 2 pre-treatment QTcF values (baseline 
and screening) to the average of the 3 post-baseline QTcF values. The IMP must be stopped for 
any confirmed post-baseline QTcF value >500 msec or increase from baseline >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.
In addition, a blood sample should be obtained for the measurement of IMP concentrations, if 
possible. 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/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 CDI-2. 

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
86
7.2.1.
Mini International Neuropsychiatric Interview for Children and Adolescents
Select MINI Kid modules are administered at screening only. 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 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 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 scale assesses past and current suicidal ideation and 
behaviors to determine suicide risk and is administered at screening. The C-SSRS children’s 
SLV scale is administered at baseline and at weeks 2, 4, 6, 9, 12, and 13. 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 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, subjects 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 

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
87
monitor, the consulting psychiatrist, and/or sponsor to determine whether the patient 
should continue in the study.
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
The CDI-2 (parent and self-report profiles) is administered at screening, baseline, and weeks 2, 
4, 6, 9, 12, and 13. As the CDI-2 is designed for children 7 to 17 years of age, children 6 years of 
age at baseline 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 individual 
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. 

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
88
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 baseline, 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 patients 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:
1. 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.
2. 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 the dose prescribed, must be immediately reported to the sponsor.
3. Misuse: Situations where the IMP is intentionally and inappropriately used not in 
accordance with the authorized product information.
4. Abuse: Persistent or sporadic, intentional excessive use of IMP, which is accompanied by 
harmful physical or psychological effects.

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
89
5. Off-label use: Situations where an IMP is intentionally used for a medical purpose not in 
accordance with the authorized product information.
6. Occupational exposure: Exposure to an IMP, as a result of one’s professional or non-
professional occupation.
7. 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 laboratory manual and by the judgement 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 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, 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 4.

Human Chorionic Gonadotrophin Test
Human chorionic gonadotrophin 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 time points specified in Table 1. The UDS detects the presence of 
drugs prohibited according to the laboratory manual. If a given parameter cannot be tested using 
urine, an alternative matrix (eg, serum) may be considered acceptable. The sponsor’s medical 
expert must be made aware in advance of, and provide approval for, drug screen parameters to 
which this will apply.
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. 

Placebo-Controlled Study–Tourette Syndrome

Study TV50717-CNS-30046
91
7.5.3.
Cytochrome P450 2D6 Genotyping
One 3-mL sample for CYP2D6 genotyping will be collected from all patients in the study at 
screening. Sample testing results will not be provided to the study team until the study is 
unblinded. 
This assessment potentially includes the association analysis of the variation in CYP2D6 gene 
with clinical treatment responses to the IMP (eg, efficacy, pharmacokinetics, tolerability, and 
safety features or disease susceptibility and severity features). See Section 8.3.1 for further 
details.
7.6.
Vital Signs
Vital signs (pulse, BP, body temperature, and respiratory rate) 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 

abnormal and clinically significant
Before pulse and BP are measured, the patient must rest in a supine or semi-erect/seated position 
for at least 5 minutes. (The same position and arm should be used each time vital signs are 
measured for a given patient). At baseline, week 4, and week 12, orthostatic BP and pulse will be 
measured after the patient is in a standing position for at least 3 minutes.
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. 
7.7.
Electrocardiography
A 12-lead ECG will be conducted 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-baseline QTcF value >500 msec or change from baseline >60 msec is found, the 
investigator should repeat the ECG assessment twice and compare the average of the 2 pre-
treatment QTcF values (baseline and screening) to the average of the 3 post-baseline QTcF 
values. The IMP must be stopped for any confirmed post-baseline QTcF value >500 msec or 
increase from baseline >60 msec.

7.8.
Physical Examinations
Physical examination, 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.
Any physical examination finding that is judged by the investigator as a 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 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.
Baseline assessment of suicidal ideation and behavior and treatment-emergent suicidal ideation 
and behavior will be assessed during the study using the C-SSRS described in Section 7.2.2. 
Depression and Suicidality as an Adverse Event
Families and caregivers of subjects in Study 30046 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.
7.10.
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 Therapy or Medication
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 
Appendix A, Table 5. The tables of 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. Prohibited medications that are associated with QTc prolongation are listed in 
Appendix A, Table 6, while prohibited antipsychotic drugs are listed in Appendix A, Table 7.
7.12.
Methods and Timing of Assessing, Recording, and Analyzing Safety 
Data
All adverse events will be reviewed on a periodic basis by the clinical project physician/medical 
monitor according to the safety monitoring plan (eg, scheduled safety reviews for TEV-50717) 
as preliminary safety databases become available.
Methods and timing 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 3.7.3.

ASSESSMENT OF PHARMACOKINETICS AND SCREENING 
ASSESSMENTS
8.1.
Pharmacokinetic Assessment
Blood samples will be obtained for the measurement of plasma concentrations of TEV-50717 
(deutetrabenazine), α-HTBZ, β-HTBZ, and other metabolites, as needed. 
Blood sampling for pharmacokinetic analysis will be performed at the week 12 visit. Two 
samples will be collected. The first sample will be collected upon arrival at the clinic. The 
second sample will be collected 2 to 3 hours after the first pharmacokinetic sample collection. 
The time between samples should be maximized in order to provide the most useful information. 
Patients with early morning visits (ie, within 2 hours of their scheduled AM dosing) should take 
their dose in the clinic after the first pharmacokinetic sample is collected.
Patients will be provided with a diary to provide critical information on dosing before the 
week 12 visit. The date and time of the last dose of study medication before the week 12 visit
should be recorded in the diary by the patient or caregiver/adult. The site will document the date 
and time of the sample collection. Prior to the clinic visit at week 12, patients will be reminded to 
record the start time of their last meal and the time of their last dose in their diary.
Plasma samples for both α-HTBZ and β-HTBZ metabolites will be pooled with previous data 
and incorporated into a population pharmacokinetic analysis. The population pharmacokinetic 
analysis will result in a final structural model that best describes the data. A covariate assessment 
will evaluate the relationship between potential covariates (ie, body weight, age, height, etc) and 
concentrations of α-HTBZ and β-HTBZ metabolites. The final population pharmacokinetic 
analysis will be included in a separate report. 
Additional details regarding sampling and handling as well as shipment and analysis of samples 
will be provided in the laboratory manual. 
8.2.
Pharmacodynamics Assessment
Exposure-response (eg, pharmacodynamic [PD] and/or safety endpoints) may be assessed if the 
appropriate data are available.
8.3.
Pharmacogenetics
8.3.1.
CYP2D6 Genotyping/Pharmacogenetics
At the screening visit, a blood sample (3 mL) will be obtained for analysis of CYP2D6 genotype. 
The patient’s genotype for CYP2D6 will remain blinded during the conduct of the study. If the 
patient elects for PGx evaluation on the optional informed consent/assent, a pharmacogenetic 
(PGx) sample (2 mL) will be obtained and stored for exploratory PGx evaluation. This PGx 
assessment will investigate the relationship between subjects’ genetic variability and study 
outcomes. Candidate genes included in this assessment may be related to, or hypothesized to be 
related to pharmacokinetics, safety features, drug mechanism of action, Tourette syndrome, or 

Placebo-Controlled Study–Tourette Syndrome

related diseases. The final list of genes to be evaluated will be determined at the time of analysis 
to be able to account for the most current research.

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.
9.1.
Sample Size and Power Considerations
It is estimated that approximately 58 patients per arm will enable a power of at least 90% to 
detect a beneficial standardized effect of 63% or more when the TEV-50717 arm is compared to 
placebo (difference of 6.0 in the change from baseline to week 12 in TTS, assuming a standard 
deviation of 9.5 in each arm) in a 2-sided type I error rate of 5% after accounting for potential 
dropouts.
 
 
 
9.2.
Analysis Sets 
9.2.1.
Intent-to-Treat Analysis Set
The intent-to-treat (ITT) analysis set will include all randomized patients. In this population, 
treatment will be assigned based on the treatment to which patients were randomized, regardless 
of which treatment they actually received. 
9.2.2.
Safety Analysis Set
The safety analysis set will include all patients who receive at least 1 dose of IMP. In this 
population, treatment will be assigned based upon the treatment patients actually receive, 
regardless of the treatment to which they were randomized. 
9.2.3.
Modified Intent-to-Treat Analysis Set
The Modified Intent-to-Treat (mITT) analysis set will include all patients in the ITT population 
who receive at least 1 dose of IMP and have both a baseline and at least 1 post-baseline YGTSS 
assessment. In this population, treatment will be assigned based on the treatment to which 
patients were randomized, regardless of which treatment they actually received. All primary and 
secondary analyses will be based on the mITT set.
9.2.4.
Per-Protocol Analysis Set
The per-protocol analysis set will include patients who are compliant with study medication 
(80% to 105%), have a YGTSS assessment at baseline and at week 9 or week 12, who have not 
taken prohibited concomitant medications as indicated in exclusion criterion, and who have no

major protocol deviations that affect the validity of the efficacy measurements. The list of 
protocol deviations will be reviewed before unblinding and major protocol deviations that could 
affect the primary and secondary variables will be determined. All exclusions from the per-
protocol analysis set will be reviewed in the blinded data review meeting before database lock.
9.3.
Data Handling Conventions
For all variables, only the observed data from the patients will be used in the primary and 
secondary statistical analyses.
9.4.
Study Population
The mITT analysis set (see Section 9.2) will be used for all efficacy summaries and analyses 
unless otherwise noted. The safety analyses set will be used for all safety summaries. Sensitivity 
analyses of primary and key secondary endpoints will be conducted using the per-protocol 
analysis set. Summaries will be presented by treatment group and for all patients.
9.4.1.
Patient Disposition
Data from patients screened; patients screened but not randomized (and reason not randomized); 
patients who are randomized; patients randomized but not treated (and reason); patients in the 
ITT, safety, and other analysis sets; 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, including medical history, prior medications, 
and ECG findings, will be examined to assess the comparability of the treatment groups and will 
be summarized using descriptive statistics. For continuous variables, descriptive statistics 
(number [n], mean, standard deviation, median, minimum, and maximum) will be provided. For 
categorical variables, patient counts and percentages will be provided. Categories for missing 
data will be presented if necessary.
9.5.
Efficacy Analysis 
9.5.1.
Primary Endpoint 
The primary efficacy endpoint for this study is the change in the TTS (of the YGTSS) from 
baseline to week 12. 
9.5.2.
Key Secondary Endpoints
Key secondary endpoints for this study are as follows: 
1.
Change in the TS-CGI score from baseline to week 12
2.
Change in the TS-PGII score from baseline to week 12

9.5.4.
Planned Method of Analysis
The mITT analysis set (see Section 9.2) will be used for all efficacy analyses. Summaries will be 
presented by treatment group. 
9.5.4.1.
Primary Efficacy Analysis
The primary analysis will be a mixed-model, repeated-measures with the change in the TTS as 
the dependent variable. The model will include fixed effects for treatment group, week (5 levels: 
weeks 2, 4, 6, 9, and 12), and the treatment group by week interaction. The baseline TTS, region,
and age group at baseline (2 levels: 6 to 11 years, 12 to 16 years) will be included as covariates. 
The unstructured covariance matrix for repeated observations within patients will be used. In 
case that the model does not converge, the Maximum-Likelihood estimation method will be used 
instead of the default Restricted Maximum-Likelihood. If the model still does not converge, then 
a simpler covariance structure with fewer parameters will be used, according to the following 
order: Heterogeneous Autoregressive (1), Heterogeneous Compound Symmetry, Autoregressive
(1), and Compound Symmetry. The least squares means of the change in TTS from baseline at 
week 12 will be compared (the active treatment arm and the placebo arm) using a 2-sided test at 
the alpha=0.05 level of significance.
In addition, actual values and changes in the TTS from baseline to each visit will be summarized 
using descriptive statistics.

9.5.4.2.
Sensitivity Analysis
Sensitivity analyses for missing data, the statistical model, and the increase in sample size will be 
provided in the statistical analysis plan.
9.5.4.3.
Key Secondary Efficacy Analyses
A hierarchical (fixed-sequence) testing approach will be used for the analysis of the primary and 
key secondary endpoints to maintain the experiment-wise type I error rate of 5%. If an endpoint 
is not statistically significant, confirmatory hypothesis testing will not be carried out on the 
remaining hypotheses, and remaining hypotheses will be considered exploratory rather than 
confirmatory. The change in the TS-CGI (1) and C&A-GTS-QOL ADL subscale (3) scores from 
baseline to week 12 will be summarized and analyzed in the same fashion as the primary 
analysis, with the exception that the baseline value of the given endpoint will be included as the 
covariate. TS-PGII (2) will be analyzed using a Cochran-Mantel-Haenszel row mean score test 
with a modified ridit scoring that controls for age group.

Multiple Comparisons and Multiplicity
The hierarchical testing method will be used to maintain the experiment-wise type I error of 5% 
level for the primary and key secondary analyses. The primary efficacy endpoint will first be 
tested at the 5% type I error level. If the p-value of the primary analysis is ≤0.05, the secondary 
hypotheses will be tested in the order listed for the secondary endpoints (Section 9.5.2) until 
either an analysis produces a p-value >0.05 or all analyses result in a p-value ≤0.05.
9.7.
Safety Endpoints and Analysis
Safety analyses will be performed on the safety analysis set.
9.7.1.
Safety Endpoints
Safety endpoints for this study are as follows:

incidence of adverse events 

observed values and changes from baseline in vital signs

observed values and change from baseline in the CDI-2 (Parent and Self-report 
versions)

observed values in the C-SSRS

observed values in ECG parameters and shifts from screening for clinically 
significant abnormal findings

observed values and changes from screening in clinical laboratory parameters 
(hematology, chemistry, and urinalysis)
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, adverse events 
determined by the investigator to be related to study treatment, serious adverse events, and 
adverse events causing withdrawal from the study. Summaries will be presented by treatment 
group and for all patients. Patient listings of serious adverse events and adverse events leading to 
withdrawal will be presented.
Observed values and changes from baseline 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. In addition, the number and percentage of patients with 
on-treatment QTcF values >450, >480, or >500 msec and change from baseline >30 or >60 msec 
will be presented.

101
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 C-SSRS and observed values and changes from baseline in the CDI-2 
(Parent and Self-report versions) will be presented by treatment group for all patients.
9.8.
Pharmacokinetic Analysis
The pharmacokinetic endpoint is listed in Section 2.3.5. Samples collected for pharmacokinetic 
analysis will be quantified for α-HTBZ and β-HTBZ of TEV-50717, and other metabolites (as 
needed), will be analyzed using population pharmacokinetic techniques. Analysis methods will 
be detailed in a separate population pharmacokinetic analysis plan. Exploratory 
pharmacokinetic/PD analysis may be performed on PD/safety endpoints.
9.9.
Planned Interim Analysis
No interim analysis is planned for this study.
9.10.
Reporting Deviations from the Statistical Plan
Deviations from the statistical plan, along with the reasons for the deviations, will be described 
in protocol amendments, the statistical analysis plan, the clinical study report, or any 
combination of these, as appropriate, and in accordance with applicable national, local, and 
regional requirements and regulations.

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 IMP administration; 
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 

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
104
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 Standard Operating Procedures (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)

incorrect packaging, or incorrect or missing labeling/labels

unexpected or unanticipated taste or odor, or both

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
105

device not working correctly or appears defective in some manner
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 
 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

patient number, blister pack, and kit numbers (if applicable) for double-blind studies

product available for return Yes/No

product was taken or used according to protocol Yes/No

description or nature of complaint

associated serious adverse event Yes/No

clinical supplies unblinded (for blinded studies) Yes/No

date and name of person receiving the complaint
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 IMP 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.

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 05
Study TV50717-CNS-30046
106
The integrity of the randomization code and corresponding blinded clinical supplies will be 
maintained whenever possible. A serious adverse event or the potential for a product quality 
problem existing beyond the scope of the complaint may be a reason to unblind the clinical 
supplies for an affected patient.
11.4.3.
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 or delegate 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.
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.
Personal medical information may be reviewed for the purpose of patient safety or for verifying 
data in the source and transcribed to the CRF. This review may be conducted by the study 
monitor, properly authorized persons on behalf of the sponsor, Global Quality Assurance, or 
competent authorities. Personal medical information will always be treated as confidential.

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.

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.
Archiving of Case Report Forms and Source Documents
13.3.1.
Sponsor Responsibilities
The sponsor or delegate will have final responsibility for the quality of the data. 
Day to day data management tasks for this study are delegated to Syneos Health, and these 
functions may be carried out as described in the SOPs for clinical studies at that organization. 
These SOPs will be reviewed by the sponsor or delegate before the start of data management 
activities. The original CRFs will be archived by the sponsor. Investigational center-specific 
CRFs will be provided to the respective investigational centers for archiving.
13.3.2.
Investigator Responsibilities
The investigator must maintain all written and electronic records, accounts, notes, reports, and 
data related to the study and any additional records required to be maintained under country, 
state/province, or national and local laws, including, but not limited to: 

full case histories

signed informed consent/assent forms

SUMMARY OF CHANGES TO PROTOCOL
17.1.
Amendment 01 Dated 22 June 2017
The primary reason for this amendment is to change aspects of the conduct, concomitant 
mediations, titration instructions, sample size, acceptable contraceptive methods, analysis of the 
data, and clinical study personnel.
This amendment is considered to be substantial (ie, requires approval by CA, 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.

1.4. Known and Potential Risks and Benefits to Human Patients (Other sections affected by this 
change: 1.4.1.1., 1.4.1.2., 1.4.2.)
Additional information regarding benefits and 
risks to patients may be found in the current IB 
and in the United States prescribing information 
for AUSTEDO™(deutetrabenazine).
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).

3.1.2 Screening Period (Other sections affected by this change: Sections 3.13, 3.13.1., 4.1, 12.1.)
After informed consent (and written assent 
and/or co-consent for patients 14 years of age 
and older, 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, laboratory testing, 
and 12-lead ECG, along with rating scales to 
assess severity, frequency, and impairment of 
tics and comorbid TS symptoms and behavioral 
status.

3.13. Study Procedures (Other sections affected by this change: Sections 5.3, 7.10)
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, including over-the-counter 
medications. Any prescribed medication should 
be reviewed with the investigator. Indication, 
dosage, and start and end dates should be 
entered on the CRF.

3.13.1. Procedures for Screening and Enrollment
After informed consent is obtained, patients 
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 designated investigator 
center number, and the last 3 digits will be 
assigned at the investigator center (eg, if the 
number assigned to the country is 01, the 
third patient screened at center 5 would be 
given the number of 01005003).

In accordance with the Declaration of Helsinki 
(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 in the event of intercurrent illness, 
adverse events, pregnancy (see Section 7.3), or 
other reasons concerning the health or 
well-being of the patient, or in the event of lack 
of cooperation. If a post-baseline QTcF value 
>500 msec or change from baseline >60 msec is 
found, the investigator should repeat the ECG 
assessment twice and compare the average of 
the 2 pre-treatment QTcF values (baseline and 
screening) to the average of the 3 post-baseline 
QTcF values. The IMP must be stopped for any 
confirmed post-baseline QTcF value >500 msec 
or increase from baseline >60 msec.

2, 4, 6, and 9.

An analysis of covariance (ANCOVA) 
model will be fit using the change from 
baseline to week 12 as the dependent 
variable, treatment group, and the baseline 
value as a covariate. For patients with 
missing data at week 12, the least favorable 
change from baseline to week 12 observed 
in either treatment group will be used as the 
dependent variable.

An ANCOVA model, as described above, 
will be fit. For patients with missing data at 
week 12, the last available change from 
baseline for the patients will be used as the 
dependent variable.

either cap, diaphragm, or sponge 
with spermicide (double barrier 
methods) are also considered 
acceptable but not highly effective 
methods of birth control.
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.
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:
1. Conduct monthly pregnancy 
testing from first dose of IMP 
until last dose of IMP and 
additional 30 days in case the 
IMP does not have a marketing 
authorization and has suspected

Information. Shorter testing 
intervals are to be considered 
depending on drug dosing

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.

Amendment 02 Dated 03 October 2017
The primary reason for this amendment is to incorporate CYP2D6 genotyping results into the 
IRT in order to allow for a dose cap to be applied in a blinded manner, update drug packaging to 
ensure blinding of CYP2D6 impairment status, reorder the statistical testing methodology (ie, the 
inclusion of TS-PGII assessment after TS-CGI and before the C&A-GTS-QOL ADL subscale), 
clarify the study day window for each visit or call, 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.

3.1.1 Overall Design and Screening Period (Other section affected by this change: 5.1)
Throughout the study, patients will 
interact regularly with investigative site 
personnel, in clinic and by telephone, 
for the evaluation of safety, tic severity, 
and behavioral status (in clinic only). 
Based on this information, theThe 
target dose for each patient receiving 
TEV-50717 will be based on body 
weight and CYP2D6 impairment status 
at baseline. 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. CYP2D6 status 
will be used by Interactive Response 
Technology (IRT) for randomization 
into the study. The dose of IMP for 
each patient will be titrated to an 
optimal level followed by maintenance 
therapy at that dose. Investigators will 
be blinded to CYP status, with a dose 
cap for poor metabolizers prespecified 
by the IRT (Table 2). The overall 
treatment period will be 12 weeks in 
duration, including a titration period of 
7 weeks, a maintenance period of 5 
weeks, followed by a washout period of 
1 week. Site- administered scales 
include the YGTSS, 
Mini 
International Neuropsychiatric

5.1 Drugs Administered During the Study
IMP (see Section 3.8) will be 
administered as oral tablets at a starting 
dose of 6 mg once daily. Titration 
schemes based on body weight at 
baseline are shown in Table 2. The 
maximum daily dose is determined by 
body weight and CYP2D6 impairment 
status at baseline and any use of strong 
CYP2D6 inhibitors (see Table 3). 
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 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.
IMP will be dispensed in the clinic. 
Patients will receive doses for 2 weeks 
at baseline, week 2, and week 4 visits 
(current dose level and next dose level) 
to cover the telephone contacts. At 
week 6 and week 9 visits, patients will 
receive doses for 3 weeks.

The starting dose is 6 mg in all 
patients. This dose will be administered 
in the evening on days 1 and 2, 
followed by AM administration for the 
remainder of week 1 (if body weight is 
<40 kg). Subsequent Daily doses of 
12 mg and higher will be administered 
twice daily in 2 divided doses, 
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. If patients 
experience insomnia while taking the 
initial 6 mg dose in the evening, they 
may switch to taking it as a morning 
dose on day 2.
•
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.

During the titration period, the dose 
of the IMP should will be adjusted 
weekly 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.

An adverse event is anyAny untoward 
medical occurrence in a patient or 
clinical investigation subject

regardless of whether it has and which 
does not necessarily have to have a 
causal relationship with this treatment. 
In this study, any adverse event 
occurring after the clinical study patient 
has signed the informed consent form 
should be recorded and reported as an 
adverse event. 
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

7.1.5 Serious Adverse Events
An additional 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.
For recording of serious adverse 
events, the study period is defined for 
each patient as the time period from 
signature of the informed consent form 
to the end of the follow up period, as 
defined in Section 7.1.2. If the

that is judged by the investigator as 
clinically significant will be recorded 
both on the source documentation, 
transcribed to and the CRF as an

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 with 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.)

At the screening visit, a blood sample 
(5 to 6 mL) will be obtained for 
analysis of CYP2D6 genotype. The 
patient’s genotype for CYP2D6 will 
remain blinded during the conduct of 
the study. If the patient elects this 
option on the optional informed 
consent, the remaining sample will be 
stored for exploratory 
pharmacogenetics (PGx) evaluation. 
This PGx assessment will investigate 
the relationship between subjects’ 
genetic variability and study outcomes. 
Candidate genes included in this 
assessment may be related to, or 
hypothesized to be related to 
pharmacokinetics, safety features, drug 
mechanism of action, Tourette 
syndrome, or related diseases. The final 
list of genes to be evaluated will be 
determined at the time of analysis to be

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:
1.
Conduct monthly pregnancy 
testing from first dose of IMP until last 
dose of IMP and additional 30 days in 
case the IMP does not have a 
marketing authorization and has 
suspected human 
teratogenicity/genotoxicity/fetotoxicity. 
Conduct monthly pregnancy testing 
and in case the IMP has a marketing 
authorization, if the IMP has a 
demonstrated or suspected human 
teratogenicity/genotoxicity/fetotoxicity 
according to Risk Safety Information. 
Shorter testing intervals are to be 
considered depending on drug dosing 
schedule.

testing, but at least at the end of 
relevant systemic exposure., in case of 
possible human

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.
Pregnant female partners of male 
study participants:
Male study participants must use 
condoms during intercourse if their 
female partners are pregnant.

Amendment 04 Dated 13 September 2018
The primary reason for this amendment is to 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 and security; update/clarify patient inclusion criteria, exclusion criteria, and withdrawal 
criteria; provide updates on allowed and prohibited medications; include additional guidance for 
evaluation and handling of suicidal ideation, suicidal behavior, and depression; and to streamline 
birth control methods language for females of childbearing potential.
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.

wholly owned subsidiary of Teva 
Pharmaceutical Products R&D, Inc, has 
developed a deuterated form of 
tetrabenazinedeutetrabenazine (referred to 
as TEV-50717 or, previously SD-809) that 
is eliminated more slowly than 
tetrabenazine.
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. and for the treatment of 
chorea associated with TD on 
30 August 2017.

Not applicable
The NOAEL (no-observed-adverse-effect 
level) 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 two factors. First, the effects

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 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

Section 5.2 Restrictions 
While patients receiving strong CYP2D6 
inhibitors (such as paroxetine, fluoxetine, 
and bupropion) at baseline 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 use of quinidine and 
terbinafine are prohibited (see Appendix A, 
Table 8).

Amendment 05 Dated 25 March 2019
The primary reason for this amendment is to update the anticipated patient enrollment numbers 
and related statistical considerations, update requirements on drug storage and security, to 
update/clarify patient inclusion criteria and withdrawal criteria, to update administrative details 
with regards to clinical study personnel contact information and vendor selection, and to provide 
additional guidance on dose suspension.
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.
