parameters, 12-lead ECGs and safety scales, an independent Data 
Monitoring Committee will monitor safety during the conduct of the 
study.
Pharmacokinetic Endpoint:
The pharmacokinetics of the alpha-dihydrotetrabenazine (α-HTBZ) and 
beta-dihydrotetrabenazine (β-HTBZ) metabolites of TEV-50717 will be explored based on 
sparse sampling (2 samples) at week 8.
General Study Design: This is a Phase 3, randomized, double-blind, placebo-controlled, 8-week
treatment study in which patients with tics associated with TS will be invited to participate. 
Patients will be randomized to low-dose TEV-50717, high-dose TEV-50717, or placebo (1:1:1). 
The target dose for each patient receiving TEV-50717 will be based on the group to which they 
are randomized, body weight at baseline, and cytochrome P450 2D6 (CYP2D6) impairment 
status. 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.
Prescreening period (up to 3 months before baseline): For patients who require discontinuation 
of certain prohibited concomitant medications 3 months before baseline (depot neuroleptics, 
botulinum toxin, or tetrabenazine), informed consent/assent, depending on the child’s age, as 
appropriate, should be obtained prior to discontinuing the prohibited medication.
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. The Mini 
International Neuropsychiatric Interview for Children and Adolescents (MINI Kid), is a short 
questionnaire (largely yes/no questions) to screen for clinically significant underlying psychiatric 
illness that may affect the subject’s eligibility. The assessment will focus on detecting major 
depression, mania/hypomania, obsessive/compulsive disorder, alcohol and substance abuse, 
attention deficit hyperactivity and conduct disorders, and psychotic disorders.
At the discretion of the investigator, the screening visit may be divided into 2 visits to reduce the 
burden on patients. If the screening visit is divided into 2 visits, the blood sample should be 
obtained during the first of the 2 visits. 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 sub-investigators 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 8/early termination visits. However, if due to 


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 03
Study TV50717-CNS-30060
14
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.
Treatment period (8 weeks): Patients who continue to remain eligible for participation in the 
study will be randomized at the baseline visit (day 1) and will receive blinded IMP to begin that 
same day (day 1) with food. Tablets should be taken with food (eg, a snack) and should not be 
taken on an empty stomach. Patients and their caregiver/adult will interact regularly with the
clinical research staff, either by telephone contact or clinic visit to assure adherence with study 
procedures and to evaluate safety and efficacy. To this end, clinic visits will be performed at 
weeks 2, 4, and 8 after baseline, in order to evaluate safety; assess tic severity with the YGTSS, 
TS-CGI, TS-PGII, and the C&A-GTS-QOL; and perform safety rating scales to augment adverse 
event reporting, concomitant medication usage, clinical laboratory examination, and 12-lead 
ECGs. Telephone contacts will occur at the end of weeks 1, 3, 6, and 7.
As this is a fixed-dose study, patients will undergo dose escalation (ie, forced titration) to their 
target dose over the first 4 weeks of treatment. If a patient experiences depression, suicidal 
ideation or behavior, anxiety, akathisia, parkinsonism, or somnolence, or any other adverse event 
that interferes with daily activity, or any adverse event that is related to IMP, a single dose 
reduction is permitted. The investigator must discuss any further dose adjustments (eg, holding 
the dose or doses) with the medical monitor.
In case of such an adverse event, the investigator will determine if a dose reduction or 
suspension is necessary. If a determination is made that a dose reduction or suspension is 
required, the medical monitor must be contacted. All available information, including the patient 
and caregiver/adult reports of adverse events, the clinical assessment of safety by the 
investigator, and information from rating scales should be incorporated in the decision. This 
reduced dose will become the patient’s dose for the remainder of the study.
Patients will return to the clinic at week 8 for the final on-treatment assessment of safety and 
efficacy. At this visit, patients will undergo a complete evaluation, including performance of all 
efficacy measures, including assessment of tic severity with the YGTSS; and complete safety 
testing, including physical and neurological examination, safety laboratory testing, 12-lead ECG, 
and all rating scales. In addition, patients will undergo pharmacokinetic sampling at week 8, at 
which time 2 pharmacokinetic specimens will be obtained 2 to 3 hours apart. Prior to the clinic 
visit on week 8, patients will be reminded to record in their diary the start time of their last meal 
and the time of their last dose of study medication before the week 8 visit. The site will 
document the date and time of the sample collection. 
Follow-up: All patients will discontinue IMP at the week 8 visit and will return 1 week later for 
evaluation of safety and tic reduction (week 9). 
Patients who complete the study may be eligible to begin participation in an open-label safety 
extension study of TEV-50717 (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. Patients not participating in the open-label safety extension study 
for TEV-50717 will have a follow-up telephone contact for safety evaluation 1 week after the 
end of the treatment period (2 weeks after their last dose of IMP).


Placebo-Controlled Study–Tourette Syndrome

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 may begin/resume tic therapy medication after the first week of the washout 
period. 
Brief Summary of Study Design for the Trial Registry(s):
Standard placebo-controlled, double-blind study design (TEV-50717 [low dose and high dose] 
vs. placebo in a 1:1:1 ratio) was chosen to determine whether IMP treatment results in a 
statistically significant effect on the tics in patients with TS.
Method of Randomization and Blinding: Patients will be randomly assigned to receive 
treatment with TEV-50717 (low dose, high dose) or matching placebo in a 1:1:1 ratio using an 
IRT based on their baseline weight and CYP impairment status. The patients will be stratified 
into 2 age groups (6- to 11-years and 12- to 16-years). The sponsor will monitor enrollment in 
age strata to ensure there is adequate representation in each stratum. 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. However, if a prioritized 
sample analysis is needed, bioanalytical personnel may be unblinded. 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.

Statistical Considerations
Sample Size Rationale: It is estimated that approximately 50 patients per arm will enable a 
power of at least 90% to detect a beneficial standardized effect of 68% or more when the 
TEV-50717 arm is compared to placebo (difference of 6.5 in the change from baseline to week 8
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 8 between high-dose TEV-50717-treated and
placebo-treated patients. 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 (3 levels: weeks 2, 4, and 8), 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. The least squares means of the change in TTS from 
baseline at week 8 will be compared between the high-dose 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 key secondary endpoints. 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 
following analyses of key secondary endpoints will be conducted:


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 03
Study TV50717-CNS-30060
20
1. The change from baseline to week 8 in TS-CGI will be analyzed using a similar model as 
the primary analysis; however, instead of change in YGTSS TTS as the dependent 
variable and baseline YGTSS TTS as a covariate, the corresponding TS-CGI values will 
be used. The comparison between high-dose TEV-50717 and placebo will be tested.
2. Using the same model as for the primary analysis, the comparison between the change in 
the TTS of the YGTSS from baseline to week 8 for low-dose TEV-50717 and placebo 
will be tested.
3. Using the same model as described in endpoint #1 above for TS-CGI, the comparison 
between the change in the TS-CGI values from baseline to week 8 for low-dose 
TEV-50717 and placebo will be tested.
4. The change from baseline to week 8 in TS-PGII will be analyzed using a 
Cochran-Mantel-Haenszel row mean score test with modified ridit scoring controlling for 
age group. The comparison between high-dose TEV-50717 and placebo will be tested.
5. Using the same model as described in endpoint #4 above for TS-PGII, the comparison 
between the change in the TS-PGII values from baseline to week 8 for low-dose 
TEV-50717 and placebo will be tested.
6. The change from baseline to week 8 in C&A-GTS-QOL ADL subscale will be analyzed 
using a similar model as the primary analysis; however, instead of change in YGTSS 
TTS as the dependent variable and baseline YGTSS TTS as a covariate, the 
corresponding C&A-GTS-QOL ADL subscale values will be used. The comparison 
between high-dose TEV-50717 and placebo will be tested.
7. Using the same model as described in endpoint #6 above for C&A-GTS-QOL ADL 
subscale, the comparison between the change in the C&A-GTS-QOL ADL subscale 
scores from baseline to week 8 for low-dose TEV-50717 and placebo will be tested.

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 analysis of key 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 metabolite plasma concentrations and will be pooled 
with previous data and analyzed using population pharmacokinetic techniques. Analysis methods 
will be detailed in a separate population pharmacokinetic analysis plan. Exploratory 
pharmacokinetic/pharmacodynamic (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 Profiles) will be presented by treatment group for all patients. 
Sensitivity Analysis: Sensitivity analyses of primary and key secondary endpoints will be 
conducted using the per-protocol analysis set. Sensitivity analyses for missing data and the 
statistical model will be provided in the statistical analysis plan.

INTRODUCTION AND 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 the prevalence 
estimates of TS among children vary widely from 0.4% to 5% in community samples (Bitsko et 
al 2014). 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 and
clonidine), typical neuroleptics (haloperidol, pimozide, and fluphenazine), or atypical 
neuroleptics (olanzapine, ziprasidone, and 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 has the 
potential to improve overall tolerability as compared to that of tetrabenazine. Data in patients 
receiving TEV-50717 for the treatment of chorea associated with Huntington 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 (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 approved for the treatment of chorea associated with HD and for the treatment 
of TD on 03 April 2017 and 30 August 2017, respectively.
The purpose of the study is to determine whether TEV-50717 is effective in the treatment of tics 
associated with TS in male and female patients between 6 and 16 years of age.
1.2.
Name and Description of Investigational Product
TEV-50717 (deutetrabenazine), the investigational medicinal product (IMP), 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 
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 tablets per dose 
strength per blister pack.
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 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 at 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 pharmacological effects. In particular, the adverse event of catalepsy, a 
known response in rats to drugs which reduce central nervous system dopamine concentrations 
(Fuenmayor and Vogt 1979), was similar in magnitude after TEV-50717 and tetrabenazine 
administration. 


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 03
Study TV50717-CNS-30060
37
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 was 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 03
Study TV50717-CNS-30060
38
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.
Clinical Studies
The clinical development plan for TEV-50717 to date includes:

1 completed Phase 3 pivotal study for the treatment of chorea associated with HD

1 completed Phase 3 long-term safety study in patients with HD

2 completed Phase 2/3 and Phase 3 studies in patients with TD

1 completed Phase 1b study in patients with TS 
Further details may be found in the IB. 
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 and TD 
patients where a population pharmacokinetic analyses including these data have been performed 
to extensively evaluate both the pharmacokinetics and pharmacokinetic-pharmacodynamic 
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 volunteers 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 robust 
pharmacokinetic sampling data obtained in healthy volunteers 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 03

40
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 A). 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.

STUDY DESIGN
3.1.
General Study Design and Study Schematic Diagram
This is a Phase 3, randomized, double-blind, placebo-controlled, 8-week treatment study in 
which patients with tics associated with TS will be invited to participate. Patients will be 
randomized to low-dose TEV-50717, high-dose TEV-50717, or placebo (1:1:1). The target dose 
for each patient receiving TEV-50717 will be based on the group to which they are randomized, 
body weight at baseline, and cytochrome P450 2D6 (CYP2D6) impairment status. 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, which 
will be used only by IRT for randomization into the study.
Prescreening period (up to 3 months before baseline): For patients who require discontinuation 
of certain prohibited concomitant medications 3 months before baseline (depot neuroleptics, 
botulinum toxin, or tetrabenazine), informed consent/assent, depending on the child’s age, as 
appropriate, should be obtained prior to discontinuing the prohibited medication.
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. The Mini 
International Neuropsychiatric Interview for Children and Adolescents, or MINI Kid, is a short 
questionnaire (largely yes/no questions) to screen for clinically significant underlying psychiatric 
illness that may affect the subject’s eligibility. The assessment will focus on detecting major 
depression, mania/hypomania, obsessive/compulsive disorder, alcohol and substance abuse, 
attention deficit hyperactivity and conduct disorders, and psychotic disorders.
At the discretion of the investigator, the screening visit may be divided into 2 visits to reduce the 
burden on patients. If the screening visit is divided into 2 visits, the blood sample should be 
obtained during the first of the 2 visits. 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.)
Treatment period (8 weeks): Patients who continue to remain eligible for participation in the 
study will be randomized at the baseline visit (day 1) and will receive blinded IMP to begin that 
same day (day 1). Tablets should be taken with food (eg, a snack) and should not be taken on an 
empty stomach. Patients and their caregiver/adult will interact regularly with the clinical research 
staff, either by telephone contact or clinic visit to assure adherence with study procedures and to 
evaluate safety and efficacy. To this end, clinic visits will be performed at weeks 2, 4, and 8 after 
baseline to evaluate safety; assess tic severity with the YGTSS, TS-CGI, TS-PGII, and the 
C&A-GTS-QOL; and perform safety rating scales to augment adverse event reporting, 
concomitant medication usage, clinical laboratory examination, and 12-lead ECGs. Telephone 
contacts will occur at the end of weeks 1, 3, 6, and 7.

As this is a fixed-dose study, patients will undergo dose escalation (ie, forced titration) to their 
target dose over the first 4 weeks of treatment. If a patient experiences depression, suicidal 
ideation or behavior, anxiety, akathisia, parkinsonism, or somnolence, or any other adverse event
that interferes with daily activity, or any adverse event that is related to IMP, a single dose 
reduction is permitted. The investigator must discuss any further dose adjustments (eg, holding 
the dose or doses) with the medical monitor.
In case of such an adverse event, the investigator will determine if a dose reduction or 
suspension is necessary. If it is determined that a dose reduction or suspension is required, the 
medical monitor must be contacted. All available information, including the patient and 
caregiver/adult reports of adverse events, the clinical assessment of safety by the investigator, 
and information from rating scales should be incorporated in the decision. This reduced dose will 
become the patient’s dose for the remainder of the study.
Patients will return to the clinic at week 8 for the final on-treatment assessment of safety and 
efficacy. At this visit, patients will undergo a complete evaluation, including performance of all 
efficacy measures (including assessment of tic severity with the YGTSS), and complete safety 
testing (including physical and neurological examination, safety laboratory testing, 12-lead ECG, 
and all rating scales). In addition, patients will undergo pharmacokinetic sampling at week 8, at 
which time 2 pharmacokinetic specimens will be obtained 2 to 3 hours apart. Prior to the clinic 
visit on week 8, patients will be reminded to record in their diary the start time of their last meal 
and the time of their last dose of study medication before the week 8 visit. The site will 
document the date and time of the sample collection. 
Follow-up: All patients will discontinue IMP at the week 8 visit and will return 1 week later for 
evaluation of safety and tic reduction (week 9). 
Patients who complete the study may be eligible to begin participation in an open-label safety 
extension Study TEV-50717 (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. Patients not participating in the open-label safety extension study 
for TEV-50717 will have a follow-up telephone contact for safety evaluation 1 week after the 
end of the treatment period (2 weeks after their last dose of IMP).
The end of study is defined as the date of the week 10 telephone contact with the last participant.
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 may begin/resume tic therapy medication after the first week of the washout 
period. 
The study duration will be approximately 17 months from January 2018.

Planned Number of Patients and Countries
The number of evaluable patients is planned to be 150. Details on sample size are given in
Section 9.
The study is planned to be conducted in approximately 10 countries in approximately 
55 investigational centers. The study is expected to start in January 2018 and last for 
approximately 17 months. 
3.3.
Justification for Study Design and Selection of Population
Standard placebo-controlled, double-blind study design (TEV-50717 [low dose and high dose] vs 
placebo in a 1:1:1 ratio) was chosen to determine whether IMP treatment results in a statistically 
significant effect on tics in patients with TS.
The population to be studied includes children and adolescents, 6 through 16 years of age. Per 
eligibility 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.
3.4.
Drug Administration
IMP will be administered as follows:

IMP should be swallowed whole and 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 1.

The total daily dose, as provided in Table 1, is divided into a twice-daily 
administration. Two tablets will be taken twice daily starting at day 1 per Table 1. 
Daily doses will be administered twice daily, approximately 8 to 10 hours apart 
during the day. Depending on the dose and arm assigned, TEV-50717 tablets and/or 
placebo tablets will be taken to maintain the blind. 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 escalations may not occur more frequently than once every 5 days.

The dose of IMP will be escalated weekly during the escalation period, according to 
Table 1.

In the case of an adverse event, the investigator is permitted to perform a single dose 
reduction of 6 mg. The investigator must discuss any further dose adjustments 
(eg, holding the dose or doses) with the medical monitor.

During the titration period, the dose of the IMP will be adjusted weekly according to 
Table 1. 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 5.1).

a Administration of a given dose will take place throughout the days indicated. The new dose starts the morning 
after the telephone contact or the morning after the clinic visit.
CYP impaired=patients who are receiving a strong CYP2D6 inhibitor or who are a CYP2D6 poor metabolizer.
Pharmacokinetic data will be reviewed at the week 8 visit. Evaluation of pharmacokinetic data 
will include review of the measurement of plasma concentrations of TEV-50717 
(deutetrabenazine), α-HTBZ, β-HTBZ, and other metabolites, as required.
3.5.
Stopping Rules for the Study
There are no formal rules for early termination of this study. During the conduct of the study, 
serious adverse events will be reviewed (Section 7.1.5) as they are reported from the 
investigational centers to identify safety concerns.
The study may be terminated by the sponsor for any reason at any time. For example, the 
sponsor should terminate the study in the event of the following:

new toxicological or pharmacological findings or safety issues that invalidate the 
earlier positive benefit-risk assessment

discontinuation of the development of the IMP

a The baseline visit (day 1) will occur the same day as the scheduled first dose of the IMP (day 1).
b Assessment will be performed at the end of study week (±3 days). 
c For patients who withdraw prematurely, an early termination visit should be conducted as soon as possible after the last dose of IMP. In addition, 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 10. 
d 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 for 
TEV-50717. 
e The screening visit may be conducted over 2 separate visits at the discretion of the investigator. If the screening visit is divided into 2 visits, the blood sample 
should be obtained during the first of the 2 visits.
f Patients will be provided with a diary at baseline, week 2, week 4, and at unscheduled visits, to record critical information on dosing. The date and time of the 
last dose of study medication before the week 8 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 8, patients will be reminded to record the start time of their last meal and the time of their last dose in 
their diary.
g Dose escalation will only occur during the dose escalation period (ie, from week 1 to week 4).
h Weight must be measured with shoes and outerwear off.
i Orthostatic blood pressure and pulse will be measured after patient is in standing position for at least 3 minutes.
j Assessment will be completed at investigator’s discretion.
k All ECGs will be performed after at least 5 minutes of 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 within 2 to 3 hours after the 
first PK sample collection. Patients with early morning visits (ie, within 2 hours of their scheduled AM dosing) should take their IMP dose in the clinic after the 
first PK sample is collected.

m The patient’s genotype for CYP2D6 will be blinded during the conduct of the study, except for the sample analysis and IRT vendor.
n For females who are postmenarchal or ≥12 years of age, a urine test will be administered at baseline and at week 4, while a serum test will be administered at 
screening, week 8, and if clinically indicated.
o 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).
p Children 6 years of age at baseline will not complete the self-report version; the caregiver/adult will complete the parent version.
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 Input from the caregiver/adult is required.
s The YGTSS, TS-CGI, TS-PGII, and 
 questionnaires should be performed before any blood draws or ECG assessments.
t 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).
u Perform the Severity Ratings of OCD symptoms (Questions 1 through 10) only. Checklist does not need to be performed.
v Contact IRT and dispense IMP and patient diary. Study drug 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 during escalation. See Table 1 for baseline weight-based dosing titration. At week 4, patients will receive doses for 4 
weeks of treatment.
w The site needs to discuss the drug status during the telephone contacts to ensure that the patient has adequate tablets, inform the patient if they should escalate, 
and remind them to bring completed blister packs to the next in-clinic visit.

Withdrawal Criteria and Procedures for the Patient
In accordance with the Declaration of Helsinki (and in accordance with the applicable country’s 
acceptance), each patient is free to withdraw from the study at any time. The investigator also 
has the right to withdraw a patient from the study if any of the following events occur:
a.
intercurrent illness
b. adverse events (any patient who experiences an adverse event may be withdrawn 
from the study or from study treatment at any time at the discretion of the investigator 
or sponsor as indicated in Section 7.1.7)
c.
pregnancy (see Section 7.3)
d. other reasons concerning the health or well-being of the patient
e.
lack of cooperation
f.
post-baseline QTcF value >500 msec or change from baseline >60 msec (as described 
in Section 7.1.7). The investigator should repeat the ECG assessment twice and 
compare the average of the 2 pre-treatment QTcF values (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 5.10.2). 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 5.7).
In addition, a patient may be withdrawn from the study as described in 
Sections 3.5, 5.10, 5.7, 7.1.7, and Appendix B. 
Should a patient decide to withdraw after administration of IMP, or should the investigator 
decide to withdraw the patient, all efforts will be made to complete and report all observations up 
to the time of withdrawal. A complete final evaluation of the patient’s withdrawal should be 
made as soon as possible after the last dose of IMP, and an explanation should be given as to 
why the patient is withdrawing or being withdrawn from the study. Assessments to be conducted 
at the early termination visit are described in Appendix B.

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 (Appendix B). 
4.4.
Replacement of Patients
A patient who is enrolled but does not complete the treatment period will not be replaced.
4.5.
Rescreening
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 Clinical Surveillance and Training 
[CST] team.) 
If the patient is rescreened, an informed consent/assent form (ICF) will need to be resigned.
4.6.
Screening Failure
Screening failures are defined as participants who consent to participate in the clinical study but 
are not subsequently randomized/enrolled in the study. Minimal information includes but is not 
limited to demography, screening failure details, eligibility criteria, and any serious adverse 
events.

TREATMENTS
5.1.
Investigational Medicinal Products Used in the Study
IMP is defined as the test IMPs, reference IMPs, and matching placebo IMPs to the respective 
test and reference IMPs.
5.1.1.
Test Investigational Medicinal Product
The investigational product is a matrix formulation and is designed as a tablet to be administered 
with food (eg, a snack) 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 will be 
supplied as 6-, 9-, 12-, 15-, and 18-mg tablets and will be packaged in blister packs and labeled 
according to applicable regulatory guidelines. 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. 
Additional details may be found in the IB for TEV-50717.
5.1.1.1.
Starting Dose and Dose Levels
Two active-dose levels were selected for this study. The target population, children 6 to 16 years 
of age, inclusive, will vary considerably in body weight. There will also be varying impairment 
of the drug metabolizing enzyme CYP2D6, whether from use of certain concomitant medications 
that inhibit the enzyme or genetic predisposition to poor metabolism of CYP2D6 substrates. 
5.1.1.2.
Dose Modification and Dose Stratification
As this is a fixed dose study, patients will undergo dose escalation (ie, forced titration) to their 
target dose over the first 4 weeks of treatment (see Section 3.4 and Table 1). If a patient 
experiences depression, suicidal ideation or behavior, anxiety, akathisia, parkinsonism, or
somnolence, or any other adverse event that interferes with daily activity, or any adverse event 
that is related to IMP, a single dose reduction is permitted. The investigator must discuss any 
further dose adjustments (eg, holding the dose or doses) with the medical monitor. 
In case of such an adverse event, the investigator will determine if a dose reduction or 
suspension is necessary. If a determination is made that a dose reduction or suspension is 
required, the medical monitor must be contacted. All available information, including the patient 
and caregiver/adult reports of adverse events, the clinical assessment of safety by the
investigator, and information from rating scales should be incorporated in the decision. This 
reduced dose will become the patient’s dose for the remainder of the study.
5.1.2.
Placebo Investigational Medicinal Product
Placebo tablets match TEV-50717 tablets. The packaging will be the same as described for 
TEV-50717 above.

5.2.
Preparation, Handling, Labeling, Storage, and Accountability for 
IMPs
5.2.1.
Storage and Security
The investigator or designee must confirm appropriate temperature conditions have been 
maintained for all IMPs received and any discrepancies are reported and resolved before use of 
the IMPs.
The IMP (TEV-50717 and the 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.
Diversion is considered to have occurred when the legal supply chain of prescription analgesic 
medicinal products is broken, and medicinal products are transferred from a licit to an illicit 
channel of distribution or use.
5.2.2.
Labeling
Supplies of IMPs will be labeled according to the current International Council for 
Harmonisation (ICH) guidelines on Good Clinical Practice (GCP) and Good Manufacturing 
Practice and will include any locally required statements. If necessary, labels will be translated 
into the local language.
5.2.3.
Accountability
Each IMP shipment will include a packing slip listing the contents of the shipment, return 
instructions, and any applicable forms.
The investigator is responsible for ensuring that deliveries of IMPs 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.
Only patients enrolled in the study may receive IMPs, and only authorized staff at the 
investigational center may supply or administer IMPs. All IMPs must be stored in a secure, 
environmentally controlled, and monitored (manual or automated) area in accordance with the 
labeled storage conditions or appropriate instructions with access limited to the investigator and 
authorized staff at the investigational center.
The investigator (or designee) will instruct the patient to store the IMP according to the 
instructions on the label, if applicable; or will give instructions in an appropriate form.
The investigator, institution, or the head of the medical institution (where applicable) is 
responsible for IMP accountability, reconciliation, and record maintenance (ie, receipt, 
reconciliation, and final disposition records).
A record of IMP accountability (ie, IMP and other study 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 blister packs IMP 
will be disposed of, as agreed with the sponsor/development partner.

5.3.
Justification for Investigational Medicinal Products
5.3.1.
Justification for Dose of Test Investigational Medicinal Product
As body weight and CYP2D6 impairment are known predictors for exposure to the active 
circulating metabolites of TEV-50717, the “high” and “low” doses will represent a target 
exposure (area under the plasma concentration-time curve [AUC], maximum observed 
concentration (Cmax) rather than a fixed milligram amount of drug. The high dose targets a mean 
(CV%) AUC of approximately 1500 ng▪hr/mL (60%) and a mean (CV%) Cmax of approximately 
100 ng/mL (39%). These targets were chosen as they represent exposure in another population 
(HD patients) receiving up to 48 mg/day that was associated with robust efficacy and favorable 
tolerability. The low dose group targets a mean (CV%) AUC of approximately 1000 ng▪hr/mL 
(60%) and a Cmax of approximately 80 ng/mL (39%). Based on Phase 3 studies in both HD and 
TD patients, exposures associated with an AUC of approximately 1000 ng▪hr/mL are still 
anticipated to be efficacious.
5.3.2.
Justification for Use of Placebo Investigational Medicinal Product
A standard placebo-controlled, double-blind study design (TEV-50717 [low dose and high dose] 
vs placebo in a 1:1:1 ratio) was chosen to determine whether IMP treatment results in a 
statistically significant effect on the tics of patients with TS. 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. Moreover, a placebo control is 
ideal for characterizing the efficacy and safety of an experimental agent in a new study 
population.
5.4.
Treatment after the End of the Study
Patients who complete the study may be eligible to begin participation in an open-label safety 
extension study of TEV-50717 (Study TV50717-CNS-30047). Patients not participating in the 
open-label safety extension study for TEV-50717 will have a follow-up telephone contact for 
safety evaluation 1 week after the end of the treatment period (2 weeks after their last dose of 
IMP).
5.5.
Restrictions
Medications prohibited before and/or during the study are described in Section 5.6. 
While patients receiving strong CYP2D6 inhibitors such as paroxetine, fluoxetine, and 
bupropion at baseline may be enrolled into this study, the removal of strong CYP2D6 inhibitors 
during treatment is discouraged as this would have an effect on exposure to active circulating 
drug. If the removal of a strong CYP2D6 inhibitor is required from a clinical perspective, the 
medical monitor should be contacted so an appropriate change in IMP can be made. The addition 
of a strong CYP inhibitor is prohibited. The use of quinidine and terbinafine are prohibited (see 
Appendix H, Table 11).
Restrictions in regard to sexual activity and required laboratory values are provided in the 
inclusion and exclusion criteria. 


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment
Study TV50717-CNS-30060
63
As with other VMAT2 inhibitors (tetrabenazine, reserpine), patients should be advised that the 
concomitant use of alcohol or other sedating drugs with TEV-50717 may have additive effects 
and cause or worsen somnolence. Given the age of the study population, the use of alcohol 
during this study is prohibited. 
Patients should be advised not to drive a car or operate dangerous machinery until they 
understand how TEV-50717 affects them.
Use of illicit drugs is prohibited from the time of signing of the informed consent/assent form 
and throughout study participation.
Patients may not donate blood from the time of informed consent/assent, while taking the IMP, 
and for 14 days after the last dose.
5.6.
Prior and Concomitant Medication or Therapy
Any prior or concomitant medication a patient has had within 3 months before IMP 
administration and up to the end of study, including follow-up, will be recorded on the CRF. 
Generic or trade name, indication, dose, and start and end dates of the administered medication 
will be recorded. The sponsor will encode all medication according to the World Health 
Organization (WHO) drug dictionary (WHO Drug).
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. 
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. Allowed strong CYP inhibitors at baseline are shown in Appendix H, Table 8.
Addition of a strong CYP inhibitor is prohibited.
Prohibited antipsychotic drugs are listed in Appendix H, Table 9. Prohibited medications that are 
associated with QTc prolongation are listed in Appendix H, Table 10.
Concomitant medication and treatment will be monitored throughout the study.
5.7.
Procedures for Monitoring Patient Compliance
The investigator will be responsible for monitoring patient compliance until completion of the 
IMP administration according to the protocol or discontinuation from IMP. A check of 
compliance with IMP intake will be performed during each visit after the IMP has been 
dispensed; 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 from the study. The IEC/IRB should be notified as required by national and local 
regulations.
Exposure to IMP will be assessed as required.

5.8.
Temporary Discontinuation of Investigational Medicinal Product
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. In the case of an adverse event, the investigator 
is permitted to perform a single dose reduction of 6 mg. The investigator must discuss any 
further dose adjustments (eg, holding the dose or doses) with the medical monitor.
If the determination that a patient requires a dose reduction or suspension is made during a 
telephone contact, an unscheduled clinic visit should be conducted as soon as practicable 
thereafter.
Dose Suspension
Suspension of study medication for up to 1 week, if warranted for patient safety, is allowed. If 
the patient restarts study medication within 7 days of suspension, the full dose of TEV-50717 
may be resumed without titration. Suspensions of study medication for adverse events must 
be reviewed with the medical monitor before therapy is restarted. If a subject’s serum 
potassium or magnesium were tested and found to be below the lower limit of normal and 
clinically significantly, the laboratory test should be repeated at least once. If the abnormality in 
the repeated laboratory test is consistent with the prior laboratory test, the IMP must be 
suspended. The Medical Monitor must be contacted to determine the appropriate investigation 
and treatment. TEV-50717 may only be restarted once serum potassium or magnesium have 
normalized.
The reason for a dose reduction or suspension must be clearly documented.
If a dose reduction or suspension occurs before a scheduled clinic visit, the clinic visit will 
be postponed so that efficacy evaluations can be performed at least 5 days after the change. 
The patients who restart IMP treatment will follow the visit schedule as outlined in Table 2. 
Patients who withdraw from the study will proceed as described in Section 4.3.
5.9.
Randomization and Blinding
This is a Phase 3, randomized, double-blind, placebo-controlled, 8-week-treatment study in 
which patients with tics associated with TS will be invited to participate. Patients will be 
randomized to either TEV-50717 (low-dose, high-dose) or matching placebo in a 1:1:1 ratio 
using an Interactive Response Technology (IRT) based on their baseline weight and CYP 
impairment status. The patients will be stratified into 2 age groups (6 to 11 years and 
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.


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment
Study TV50717-CNS-30060
65
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, INC (referred to hereafter as Nuvelution TS Pharma).
The staff member at the investigational center who will dispense the IMP will not know the 
treatment given to each patient.
5.10.
Maintenance of Randomization and Blinding
Patients will be randomly assigned to receive treatment with TEV-50717 (low dose, high dose) 
or matching placebo in a 1:1:1 ratio using an IRT based on their baseline weight and CYP 
impairment status. The patients will be stratified into 2 age groups (6- to 11-years and 12- to 16-
years). The sponsor will monitor enrollment in age strata to ensure there is adequate 
representation in each stratum. 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. However, if a prioritized sample analysis is needed, 
bioanalytical personnel may be unblinded.
5.10.1.
Maintenance of Randomization
Patient randomization codes will be maintained in a secure location within Syneos Health. At the 
time of analysis, when treatment codes are needed, the Syneos Health statistician assigned to the 
study will make a request to unblind, and will receive the unblinded codes and unblinded IMP 
assignment according to the processes defined in the relevant Standard Operating Procedure.
5.10.2.
Blinding and Unblinding
Blinded pharmacokinetic data may be assessed during the study. For patients who have 
pharmacokinetic sample bioanalysis or data analysis conducted, the individuals responsible for 
sample bioanalysis and other responsible personnel will know who received active IMP and who 
received placebo during the study (of those patients only). Personnel responsible for bioanalysis 
will be provided with the randomization code to facilitate the analysis. However, the personnel 
responsible for bioanalysis and pharmacokinetic data analysis will not have access to clinical 
safety and efficacy data, 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 the 
concentration data of an individual patient).
For information about personnel who may be aware of IMP assignments, see Section 5.9. These 
individuals will not be involved in the conduct of any study procedures or assessment of any 
adverse events.


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment
Study TV50717-CNS-30060
66
In case of a serious adverse event, pregnancy, or in cases when knowledge of the IMP 
assignment is needed to make treatment decisions, the investigator may unblind the patient’s 
IMP assignment as deemed necessary, mainly in emergency situations. Individual randomization
codes, indicating the IMP assignment for each randomized patient, will be available to the 
investigator(s) or pharmacist(s) at the investigational center via the Randomization and Trial 
Supply Management (RTSM), both via telephone and internet. If possible, the sponsor should be 
notified of the event before breaking of the code. If this is not possible, the sponsor should be 
notified immediately afterwards and the patient’s IMP assignment should not be given. Breaking 
of the randomization code can always be performed by the investigational center 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 on the 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. Assignment of IMP should 
not be recorded in any study documents or source document.
In blinded studies, for an adverse event defined as a suspected unexpected serious adverse 
reaction (SUSAR) (ie, reasonable possibility; see Section 7.1.4), Global Patient Safety and 
Pharmacovigilance (GPSP) may independently request that the blind code be broken (on a 
case-by-case basis) to comply with regulatory requirements. The report will be provided in an 
unblinded manner for regulatory submission. If this occurs, blinding will be maintained for the 
investigator and for other personnel involved in the conduct of the study and analysis and 
reporting of the data.
5.10.3.
Data Monitoring Committee
During the conduct of this study, an IDMC will review accumulating safety and efficacy data on 
a regular basis to ensure the continuing safety of the study patients and 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.

ASSESSMENT OF EFFICACY
Site-administered efficacy scales include YGTSS and 
, and self-administered efficacy 
scales include 
 TS-PGII, 
, and C&A-GTS-QOL. 
6.1.
Primary Efficacy Measure and Justification
The primary efficacy measure is the TTS of YGTSS. 
The YGTSS is administered at screening; baseline; and weeks 2, 4, 8, and 9:

Complete assessment (Checklist and Severity Ratings) at screening, baseline, and 
weeks 4 and 8

Severity Ratings assessment only at weeks 2 and 9

Input from caregiver/adult is required for all subjects 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 the 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 
GSS can then be determined by combining the patient’s severity rating with the TTS.
A reference sample is provided in Appendix I.
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, 8, and 9. 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 N.
6.2.2.
Tourette Syndrome-Patient Global Impression of Impact
The TS-PGII is administered at baseline and weeks 2, 4, 8, and 9. Input from the caregiver/adult
is permitted.
The TS-PGII is a single-item questionnaire that asks the patient to assess their degree of impact 
due to current tics. The TS-PGII uses a 5-point scale, ranging from not at all (1) to very much 
(5), to assess overall response to therapy. In general, patient-rated global measures of change 


Placebo-Controlled Study–Tourette Syndrome

have face validity and have been shown to correlate with disability for a number of chronic 
conditions.
A reference sample is provided in Appendix O.
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 4, and week 8. 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 Q.

ASSESSMENT OF SAFETY
In this study, safety will be assessed by qualified study personnel by evaluating: reported adverse 
events, clinical laboratory test results, vital signs measurements, ECG findings, physical 
examination findings (including body weight and height measurements), use of concomitant 
medications, 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 any washout period 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 of Adverse Events
For recording of adverse event, 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. For this 
study, there will be 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 the open-label safety extension Study TV50717-CNS-30047.
For subjects who experience an adverse event or serious adverse event after signing a 
prescreening ICF for Study TV50717-CNS-30060, the event will be documented in the subject 
source documents and Electronic Data Capture (EDC) systems. For serious adverse events, the 
serious adverse event form must be completed in addition, and the serious adverse event must be 
reported immediately to the sponsor (Section 7.1.5.3.1). If the subject attends the screening visit, 
the adverse event or serious adverse event identified during the prescreening period will be 
considered medical history. For data entry purposes in EDC, the stop date for the prescreening 
adverse event or serious adverse event will be the date of the screening visit, and the start date 
for the associated medical history will be the date of the screening visit.
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 (Section 7.1.5.3.1). The investigator 
does not need to actively monitor patients for adverse events after the defined period. Serious 
adverse events occurring to a patient after the treatment of that patient has ended should be 
reported to the sponsor if the investigator becomes aware of them, following the procedures 
described in Section 7.1.5.3.1.
At each contact with the patient, the investigator or designee must question the patient about 
adverse events by asking an open-ended question such as “Have you had any unusual symptoms 
or medical problems since the last visit? If yes, please describe.” All reported or observed signs 
and symptoms will be recorded individually, except when considered manifestations of a 
medical condition or disease state. A precise diagnosis will be recorded whenever possible. 
When such a diagnosis is made, all related signs, symptoms, and any test findings will be 
recorded collectively as a single diagnosis on the CRF and, if it is a serious adverse event, on the 
serious adverse event form.
The clinical course of each adverse event will be monitored at suitable intervals until resolved,
stabilized, or returned to baseline; or until the patient is referred for continued care to a health 
care professional; or until a determination of a cause unrelated to the IMP or study procedure is 
made.
The onset and end dates, duration (in case of adverse event duration of less than 24 hours), action 
taken regarding IMP, treatment administered, and outcome for each adverse event must be 
recorded both on the source documentation and the CRF.
The relationship of each adverse event to IMP and study procedures, and the severity and 
seriousness of each adverse event, as judged by the investigator, must be recorded as described 
below.
Further details are given in the safety monitoring plan.

7.1.3.
Severity of an Adverse Event
The severity of each adverse event must be recorded as 1 of the following:
Mild:
No limitation of usual activities
Moderate: Some limitation of usual activities
Severe:
Inability to carry out usual activities
7.1.4.
Relationship of an Adverse Event to the Investigational Medicinal Product
The relationship of an adverse event to the IMP is characterized as follows:
Table 5:
The Relationship of an Adverse Event to the IMP
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.


Placebo-Controlled Study–Tourette Syndrome

74
For recording of serious adverse event, 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 as 
defined in Section 7.1.2. Serious adverse events occurring in a patient after the end of the 
follow-up period should be reported to the sponsor if the investigator becomes aware of them, 
following the procedures described in Section 7.1.5.3.1.
7.1.5.1.
Definition of a Serious Adverse Event
A serious adverse event is an adverse event occurring at any dose that results in any of the 
following outcomes or actions:

results in death

is 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 and caregiver/adult signed the informed 
consent/assent form will not be considered serious adverse events, unless there was 
worsening of the pre-existing 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 
>3x the upper limit of normal (ULN)

total bilirubin increase of >2x 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.
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.
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 LSO or designee (a CRO 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


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment
Study TV50717-CNS-30060
76

severity

explanation of assessment of relatedness

concomitant medication (including doses, routes of administration, and regimens) and 
treatment of the event

pertinent laboratory or other diagnostic test data

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/CRO 
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/CRO 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 7.2).
7.1.5.3.2. Sponsor Responsibility
If a serious unexpected adverse event is believed to be related to the IMP or study procedures, 
the sponsor will take appropriate steps to notify all investigators participating in sponsored 
clinical studies of TEV-50717 and the appropriate competent authorities (and IEC/IRB, as 
appropriate).
In addition to notifying the investigators and competent authorities (and IEC/IRB, as 
appropriate), other action may be required, including the following:

altering existing research by modifying the protocol

discontinuing or suspending the study


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment
Study TV50717-CNS-30060
77

modifying the existing consent/assent form and informing all study participants of 
new findings

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. 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

78
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-V™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 I.
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. C-SSRS children’s SLV 
scale is administered at baseline and at weeks 2, 4, 8, and 9. 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 


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment
Study TV50717-CNS-30060
79
the medical 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 K.
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, 8, and 9. 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 J.
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/CRO) with the completed pregnancy form. The 


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment
Study TV50717-CNS-30060
80
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 patient participating in the study does not continue to term, 1 of 
the following actions will be taken:

For a spontaneous abortion, report as a serious adverse event. 

For an elective abortion due to developmental anomalies, report as a serious adverse 
event.

For an elective abortion not due to developmental anomalies, report on the pregnancy 
form; do not report as an adverse event.
7.4.
Medication Error and Special Situations Related to the 
Investigational Medicinal Products
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
(Appendix C), or as a deviation, in the patients source documents, regardless of whether or not 
an adverse event occurs as a result.
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 that 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.
5. Off-label use: Situations where an IMP is intentionally used for a medical purpose not in 
accordance with the authorized product information.


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment
Study TV50717-CNS-30060
81
6. Occupational exposure: Exposure to an IMP, as a result of one’s professional or non-
professional occupation.
7. Breastfeeding: Suspected adverse reactions which 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 value 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 
withdrawal of IMP, or further diagnostic work-up. (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.).

7.5.2.2.
Urine Drug Screen
A urine drug screen (UDS) will be performed at the time points specified in Table 2. 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 above drugs or their metabolites, without medical explanation, 
will preclude the patient from enrollment or continued participation in the study.
7.5.2.3.
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, pharmacokinetic, tolerability, and 
safety features or disease susceptibility and severity features). 
7.6.
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 2.
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. 
7.7.
Vital Signs
Vital signs (pulse, BP, body temperature, and respiratory rate) will be measured at the time 
points detailed in Table 2. 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 BP and pulse 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.) For any abnormal vital sign value, 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.

7.8.
Electrocardiography
A 12-lead ECG will be recorded at the time points detailed in Table 2. 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.
7.9.
Assessment of Suicidality
TEV-50717 is considered to be central nervous system (CNS)-active. In addition, there have 
been some reports of suicidal ideation or behavior as reported in the product label when it has 
been given to some patients with certain conditions. The sponsor considers it important to 
monitor for such events before and during this clinical study.
Some CNS-active IMPs may be associated with an increased risk of suicidal ideation or behavior 
when given to some patients with certain conditions. Although this IMP or other similar 
medicinal products in this class have not been shown to be associated with an increased risk of 
suicidal thinking or behavior when given to this study population, the sponsor considers it 
important to monitor for such events before or during this clinical study.
The study population being administered TEV-50717 should be monitored appropriately and 
observed closely for suicidal ideation and behavior or any other unusual changes in behavior. 
Consideration should be given to discontinuing TEV-50717 in participants who experience signs 
of suicidal ideation or behavior; 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 Columbia-Suicide Severity Rating Scale
described in Section 7.2.2.
Depression and Suicidality as an Adverse Event 
Families and caregivers of subjects 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.


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment
Study TV50717-CNS-30060
85
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 K.
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 2. Any neurological examination finding that is judged by the 
investigator as a potentially clinically significant change (worsening) compared with the 
screening value will be considered an adverse event, recorded on the CRF, and monitored as 
described in Section 7.1.2. 
7.11.
Concomitant Medication or Treatment
Concomitant therapy or medication usage will be monitored throughout the study. 
Parents/patients will be instructed during the course of the study to notify the investigator if any 
new medication is prescribed/administered, including over-the-counter medications. Any 
prescribed/administered medication should be reviewed with the investigator.
Medications that are allowed, provided that conditions outlined in the table are met, are shown in 
Appendix H, Table 7. The tables for allowed and prohibited medications are not comprehensive 
and may not include all possible concomitant medications.
The medical monitor must be contacted if a patient is receiving (or has to begin or stop receiving 
during the study) a medication that is associated with QTc prolongation or that is a known strong
CYP inhibitor, or if there are any questions regarding any medication not listed in Appendix H. 
Prohibited medications that are associated with QTc prolongation are listed in Appendix H, 
Table 10, while prohibited antipsychotic drugs are listed in Appendix H, Table 9.

ASSESSMENT OF PHARMACOKINETICS / 
PHARMACODYNAMICS
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 required. 
Blood sampling for pharmacokinetics will be performed at the week 8 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 at baseline, 
week 2, week 4, and at unscheduled visits. The date and time of the last dose of study medication 
before the week 8 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 8, 
patients will be reminded to record the start time of their last meal and the time of their last dose 
in their diary.
Blood samples (5 mL) will be collected via venipuncture for plasma concentration measurements 
of TEV-50717 and metabolites or other analytes. 
The dates and times of IMP administration and the date and time of each pharmacokinetic
sample will be recorded on the source documentation and transcribed onto the CRF. 
An exploratory analysis of the pharmacokinetics of active metabolites on the pharmacodynamics
or safety endpoints may be performed.
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 pharmacogenetics (PGx) evaluation on the optional informed consent/assent, a 
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 


Placebo-Controlled Study–Tourette Syndrome

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 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 CSR.
9.1.
Sample Size and Power Considerations
It is estimated that approximately 50 patients per arm will enable a power of at least 90% to 
detect a beneficial standardized effect of 68% or more when the TEV-50717 arm is compared to 
placebo (difference of 6.5 in the change from baseline to week 8 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, regardless of whether 
or not a patient took any IMP. 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.
Modified Intent-to-Treat Analysis Set
The modified intent-to-treat (mITT) analysis set is a subset of the ITT analysis set including only 
patients who receive at least 1 dose of IMP and who have both a baseline and at least 
1 postbaseline YGTSS assessment.
In the mITT analysis set, 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.
9.2.3.
Safety Analysis Set
The safety analysis set will include all randomized patients who receive at least 1 dose of IMP.
In the safety analysis set, treatment will be assigned based on the treatment the patients actually 
received, regardless of the treatment to which they were randomized, unless otherwise specified.
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 weeks 2, 4, and 8, and 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.

9.2.5.
Additional Analyses Sets
The pharmacokinetic analysis set will include those patients from the safety analysis set who 
have sufficient data to be included in the population pharmacokinetic analysis.
9.3.
Data Handling Conventions
For all variables, only the observed data from the patients will be used in the statistical analyses, 
ie, there is no plan to estimate missing data, unless otherwise specified. For the sensitivity 
analysis of the primary and key secondary efficacy endpoints, detailed data imputation rules will 
be described in the statistical analysis plan.
9.4.
Study Population
The mITT analysis set (see Section 9.2.2) 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.

9.5.5.1.
Primary Efficacy Analysis
The primary efficacy endpoint for this study is the change in the TTS of the YGTSS from 
baseline to week 8 between high-dose TEV-50717-treated and placebo-treated patients. 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 (3 levels: 
weeks 2, 4, and 8), 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. The least 
squares means of the change in TTS from baseline at week 8 will be compared between the high-
dose 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.
9.5.5.2.
Sensitivity Analysis
Sensitivity analyses for missing data and the statistical model will be provided in the statisitical 
analysis plan.
9.5.5.3.
Key Secondary Efficacy Analyses
A hierarchical (fixed-sequence) testing approach will be used for the analysis of the key 
secondary endpoints. If an endpoint is not statistically significant, confirmatory hypothesis 
testing will not be not carried out on the remaining hypotheses, and remaining hypotheses will be 
considered exploratory rather than confirmatory. The following analyses of key secondary 
endpoints will be conducted:
1. The change from baseline to week 8 in TS-CGI will be analyzed using a similar model as 
the primary analysis; however, instead of change in YGTSS TTS as the dependent 
variable and baseline YGTSS TTS as a covariate, the corresponding TS-CGI values will 
be used. The comparison between high-dose TEV-50717 and placebo will be tested.
2. Using the same model as for the primary analysis, the comparison between the change in 
the TTS of the YGTSS from baseline to week 8 for low-dose TEV-50717 and placebo 
will be tested.
3. Using the same model as described in endpoint #1 above for TS-CGI, the comparison 
between the change in the TS-CGI values from baseline to week 8 for low-dose 
TEV-50717 and placebo will be tested.
4. The change from baseline to week 8 in TS-PGII will be analyzed using a 
Cochran-Mantel-Haenszel-row mean score test with modified ridit scoring controlling for 
age group. The comparison between high-dose TEV-50717 and placebo will be tested.
5. Using the same model as described in endpoint #4 above for TS-PGII, the comparison 
between the change in the TS-PGII values from baseline to week 8 for low-dose 
TEV-50717 and placebo will be tested.
6. The change from baseline to week 8 in the C&A-GTS-QOL ADL subscale will be 
analyzed using a similar model as the primary analysis; however, instead of change in 
YGTSS TTS as the dependent variable and baseline YGTSS TTS as a covariate, the 


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment

93
corresponding C&A-GTS-QOL ADL subscale values will be used. The comparison 
between high-dose TEV-50717 and placebo will be tested.
7. Using the same model as described in endpoint #6 above for the C&A-GTS-QOL ADL 
subscale, the comparison between the change in the C&A-GTS-QOL ADL subscale 
scores from baseline to week 8 for low-dose TEV-50717 and placebo will be tested.

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 analysis of key secondary endpoints until 
either an analysis produces a p-value >0.05 or all analyses result in a p-value ≤0.05.

9.7.1.
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 


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment
Study TV50717-CNS-30060
95
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 Profiles) will be presented by treatment group for all patients. 
9.8.
Tolerability Analysis
Tolerability was not specifically defined.
9.9.
Pharmacokinetic Analysis
Blood samples will be obtained for the measurement of plasma concentrations of TEV-50717 
(deutetrabenazine), α-HTBZ, β-HTBZ, and other metabolites, as required. 
Blood sampling for pharmacokinetics will be performed at the week 8 visit. Two samples will be 
collected. The first sample will be collected upon arrival at the clinic. The second sample will be 
collected within 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 at baseline, 
week 2, week 4, and at unscheduled visits. The date and time of the last dose of study medication 
before the week 8 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 8, 
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 metabolite concentrations will be pooled with 
previous data and analyzed using population pharmacokinetics techniques. The population 
pharmacokinetics 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.
9.10.
Planned Interim Analysis
There will be no formal interim analysis.

1.3.1.3 Toxicology
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).

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

any further dose adjustments (eg, holding the dose or 
doses) with the medical monitor.
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-

Depression and Suicidality as an Adverse Event 
Families and caregivers of subjects 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.

Using the same repeated measures model as described 
for the primary analysis, the groups will be compared 
using the per protocol population.

The primary analysis at week 8 will be repeated on a 
complete data set using multiple imputation 
methodology for imputing missing data using a 
missing not at random (MNAR) missing data 
assumption to investigate when statistical significance 
disappears.
Data will be imputed for patients missing data at week 8 using 
the predictive mean matching multiple imputation method 
(Heitjan and Little 1991, Schenker and Taylor 1996). Under a 
missing not at random data assumption, patients treated with 
TEV 50717 who discontinue the study for any reason other 
than “Lost to Follow Up” will have their missing data at 
week 8 imputed. Only placebo patients will be included in the 
imputation model, while all other patients will have data 
imputed from a model derived from their assigned treatment 
group. The imputation model will include age group at 
baseline, baseline TTS score, and TTS scores at all visits up to 
week 8 where the TTS is scheduled to be collected. The 
resulting complete, imputed datasets will each be analyzed 
using the same model as the primary analysis model, and the

While patients receiving strong CYP2D6 inhibitors (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 addition of a strong CYP inhibitor is prohibited.

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).
Any female patient becoming pregnant during the study will 
discontinue treatment. All patients who become pregnant will be 
monitored for the outcome of the pregnancy (including spontaneous 
or voluntary termination). 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 termination from the study will be reported as 
an adverse event or serious adverse event, as appropriate.
The investigator is not required to report patients who are found to be 
pregnant between screening and baseline, provided no protocol

TESTING
Contraception recommendations and pregnancy testing should 
encompass all IMPs as well as non investigational medicinal 
products, eg, background therapy, and the measures to be followed 
should be based on the medicinal product with highest risk.
Assessment of likelihood of possible interaction between IMP or 
concomitant medications and hormonal contraception should be 
conducted. Hormonal contraception may be susceptible to interaction 
with the IMP, which may reduce the efficacy of the contraception 
method, eg, CYP 4A inducers. In case of suspected interaction, 
hormonal contraceptive alone may not be sufficient. In the absence of 
clinical pharmacokinetic interaction study data in IMPs with 
demonstrated or suspected human teratogenicity/fetotoxicity, 
recommendation for use of hormonal contraceptives should be 
thoroughly justified by the sponsor. Additional contraceptive 
methods, including supplementary barrier methods, may be 
considered.
Females of childbearing potential are defined as:

not surgically (documented hysterectomy, bilateral 
oophorectomy, or bilateral salpingectomy) or 
congenitally sterile


who are postmenarchal or ≥12 years of age 
Highly effective birth control methods:
Highly effective birth control methods are methods that can 
achieve a failure rate of less than 1% per year when used 
consistently and correctly are considered. Such methods include:

Combined estrogen and progestogen hormonal 
contraception (oral, intravaginal, transdermal) 
associated with inhibition of ovulation; these should 
be initiated at least 1 month before the first dose of 
IMP

Progestogen-only hormonal contraception (oral, 
injectable, implantable) associated with inhibition of 
ovulation; these should be initiated at least 1 month 
before the first dose of IMP
Unacceptable birth control methods:
Periodic abstinence (calendar, symptothermal, post-ovulation 
methods), withdrawal (coitus interruptus), spermicides only, and 
lactational amenorrhoea method (LAM) are not acceptable

correctly are considered. Such methods include:

Combined estrogen and progestogen hormonal 
contraception (oral, intravaginal, transdermal) 
associated with inhibition of ovulation; these should be

IMPs without suspected teratogenicity/genotoxicity) 
and 1 month (for IMPs potentially 
teratogenic/genotoxic)1 month before the first dose of 
IMP
Acceptable birth control methods:
Acceptable birth control methods that result in a failure rate of more 
than 1% per year include: progestogen only oral hormonal 
contraception for which the inhibition of ovulation is not the primary 
mode of action; male or female condom with or without spermicide; 
cap, diaphragm, or sponge with spermicide. The combination of male
condom with 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

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 women of childbearing 
potential 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 women of childbearing potential:
7.
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.
Pregnancy tests in women of childbearing potential:
1.
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.
2.
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

APPENDIX B.STUDY PROCEDURES AND ASSESSMENTS BY VISIT
1. Procedures for Prescreening (Up to 3 Months)
The prescreening visit will take place not more than 3 months before the baseline visit. The 
following procedure will be performed at prescreening:

obtain written informed consent/assent, depending on the child’s age, as appropriate,
before any study-related procedures are performed
2. Procedures for Screening (Up to 31 days)
The screening visit will take place up to 31 days before the baseline visit. 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 Clinical Surveillance and Training [CST] team.)
The Yale Global Tic Severity Scale (YGTSS) questionnaire should be performed before any 
blood draws or electrocardiogram (ECG) assessments. All investigators and sub-investigators 
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 8/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. The following procedures will be performed at
screening:

obtain written informed consent/assent, depending on the child’s age, as appropriate, 
before any study-related procedures are performed

conduct clinic visit (may be conducted over 2 separate visits at the discretion of the 
investigator [Note: If the screening visit is divided into 2 visits, the blood sample 
should be obtained during the first of the 2 visits.])

review eligibility (inclusion and exclusion) criteria


APPENDIX C.QUALITY CONTROL AND QUALITY ASSURANCE
Protocol Amendments and Protocol Deviations 
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.
Protocol Deviations
Any deviation from the protocol that affects, to a significant degree, (a) the safety, physical, or 
mental integrity of the patients in the study and/or (b) the scientific value of the study will be 
considered a protocol violation. Protocol deviations 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 deviations will be identified and recorded by 
investigational center personnel in the CRF. All protocol deviations will be reported to the 
responsible IEC/IRB, as required.
When a protocol violation is reported, the sponsor will determine whether to withdraw 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.
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.


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 03
Study TV50717-CNS-30060
164
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(s) 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(s) will contact the investigator and visit the investigational center according 
to the monitoring plan. The study monitor will be permitted to review and verify the various 
records (CRFs and other pertinent source data records, including specific electronic source 
document relating to the study) to verify adherence to the protocol and to ensure the 
completeness, consistency, and accuracy of the data being recorded.
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 during the course of these 
monitoring visits or provided in follow-up written communication.
Audit and Inspection
The sponsor may audit the investigational center to evaluate study conduct and compliance with 
protocols, SOPs, GCP guidelines, and applicable regulatory requirements. The sponsor’s Global 
Clinical Quality Assurance, independent of Global Specialty 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.

APPENDIX D.ETHICS
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 patient. The patient 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 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 (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. The patient’s willingness to participate in the study will be 
documented in the informed consent form, which will be signed and personally dated by the 
patient and 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 that the patient is 
free to refuse participation in the study and free to withdraw from the study at any time without 
prejudice to future treatment.
The investigator, or a qualified person designated by the investigator, should fully inform the 
patient and each 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 each parent/legally acceptable representative and the patient. The patient and each
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 each parent/legally 
acceptable representative, and a signed and dated assent and/or co-consent form 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 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 and assent forms, and copies will be given to the patients (and each parent/legally 
acceptable representative). It will also be explained to the patients (and each 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.
Competent Authorities and Independent Ethics Committees/Institutional Review Boards
Before this study starts, the protocol will be submitted to the national competent authority and to 
the respective IEC/IRB for review. As required, the study will not start at a given investigational

166
center before the IEC/IRB and competent authority (as applicable) for the investigational center 
give written approval or a favorable opinion.
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 the CRF. This review may be conducted by the study monitor, properly 
authorized persons on behalf of the sponsor, Global Quality Assurance (GCA), or competent 
authorities. Personal medical information will always be treated as confidential.
Registration of the Clinical Study
In compliance with national and local regulations and in accordance with Teva standard 
procedures, this clinical study will be registered on trials registry websites.

APPENDIX F.
LOST TO FOLLOW-UP
A patient will be considered lost to follow-up if he/she repeatedly fails to return for scheduled 
visits and is unable to be contacted by the investigational center.
The following actions must be taken if a patient fails to return to the investigational center for a 
required study visit:

The investigational center must attempt to contact the patient and reschedule the 
missed visit as soon as possible and counsel the patient on the importance of 
maintaining the assigned visit schedule and ascertain whether or not the patient 
wishes to and/or should continue in the study.

In cases in which the patient is deemed lost to follow-up, the investigator or designee 
must make every effort to regain contact with the patient (where possible, 3 telephone 
calls and, if necessary, a certified letter to the patient’s last known mailing address or 
local equivalent methods). These contact attempts should be documented in the 
patient’s medical record.

Should the patient continue to be unreachable, he/she will be considered to have 
withdrawn from the study with a primary reason of ‘lost to follow-up’.

APPENDIX G.
HANDLING, LABELING, STORAGE, AND 
ACCOUNTABILITY FOR IMP
Storage and Security
The investigator or designee must confirm appropriate temperature conditions have been 
maintained for all IMPs received and any discrepancies are reported and resolved before use of 
the IMPs.
The IMP (TEV-50717 and the 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.
Diversion is considered to have occurred when the legal supply chain of prescription analgesic 
medicinal products is broken, and medicinal products are transferred from a licit to an illicit 
channel of distribution or use.
Labeling
Supplies of IMPs will be labeled in accordance with the current International Council for 
Harmonisation (ICH) guidelines on GCP and Good Manufacturing Practice and will include any 
locally required statements. If necessary, labels will be translated into the local language.
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 blister packs will be 
disposed of, as agreed with the sponsor/development partner.

PRODUCT COMPLAINTS
Clinical Product Complaints
A clinical product complaint is defined as a problem or potential problem with the physical 
quality or characteristics of clinical IMP 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

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 an IMP, all relevant samples (eg, the remainder of the patient’s IMP supply) should be 
sent back to the sponsor for investigative testing whenever possible.
1. Product Complaint Information Needed from the Investigational Center
In the event that the product complaint form cannot be completed, the investigator will provide
the following information, as available:

investigational center number and principal investigator name

name, phone number, and address of the source of the complaint

clinical protocol number

patient identifier (patient study number) and corresponding visit numbers, if 
applicable

product name and strength for open-label studies

patient number, blister pack, and kit numbers (if applicable) for double-blind or 
open-label studies

product available for return Yes/No

product was taken or used according to protocol Yes/No


Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 03
Study TV50717-CNS-30060
241

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.
2. Handling of Investigational Medicinal Product(s) at the Investigational Center(s)
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.
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.
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).
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.
Medical device incidents, including those resulting from malfunctions of the device, must be 
detected, documented, and reported by the investigator throughout the study.

DATA MANAGEMENT AND RECORD KEEPING
Direct Access to Source Data and Documents
All patient data must have supportive original source documentation in the medical records, or 
equivalent, before they are transcribed to the CRF. Data may not be recorded directly on the CRF 
and considered as source data unless the sponsor provides written instructions specifying which 
data are permitted to be recorded directly to the CRF.
If data are processed from other institutions or by other means (eg, clinical laboratory or central 
image center) the results will be sent to the investigational center, where they will be retained but 
not transcribed to the CRF, unless otherwise noted in the protocol. These data may also be sent 
electronically to the sponsor (or organization performing data management).
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. The investigator must maintain a confidential patient identification list that allows 
the unambiguous identification of each patient.
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 (USA) and documents of other concerned 
competent authorities. Before using the CDMS, it will be fully validated and 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.
If data are processed from other sources (eg, central laboratory, bioanalytical laboratory, central 
image center, electronic patient-reported outcome [ePRO] tablet), these data will be sent to the 
investigational center, where they will be retained but not transcribed to the CRF, unless 
otherwise noted in the protocol. These data may also be sent electronically to the sponsor (or 
organization performing data management). All patient data must have supportive original 
source documentation in the medical records, or equivalent, before they are transcribed to the 
CRF. Data may not be recorded directly on the CRF and considered as source data unless the 
sponsor provides written instructions specifying which data are permitted to be recorded directly 
to the CRF.
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.

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.
Archiving of Case Report Forms and Source Documents
Sponsor Responsibilities
The original CRFs will be archived by the sponsor. Investigational center-specific CRFs will be 
provided to the respective investigational centers for archiving.
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

Placebo-Controlled Study–Tourette Syndrome
Clinical Study Protocol with Amendment 03
Study TV50717-CNS-30060
244
The investigator will retain all records related to the study and any additional records required, as 
indicated by the protocol and according to applicable laws and regulations, until the CRO or 
sponsor notifies the institution in writing that records may be destroyed. If, after 25 years from
study completion, or earlier in the case of the investigational center closing or going out of 
business, the investigator reasonably determines that study record retention has become unduly 
burdensome, and sponsor has not provided written notification of destruction, then the 
investigator may submit a written request to sponsor at least 60 days before any planned 
disposition of study records. After receipt of such request, the sponsor may make arrangements 
for appropriate archival or disposition, including requiring that the investigator deliver such 
records to the sponsor. The investigator shall notify the sponsor of any accidental loss or 
destruction of study records.

Purpose
The purpose of this statistical analysis plan (SAP) is to ensure that the data listings, summary tables and 
figures which will be produced, and the statistical methodologies that will be used, are complete and 
appropriate to allow valid conclusions regarding the study objectives.
Responsibilities
Syneos Health will perform the statistical analyses and are responsible for the production and quality 
control of all tables, figures and listings.
Nuvelution and Teva will perform review of all tables, figures and listings before the finalization.
Timings of Analyses
The primary analysis of safety and efficacy is planned after all patients complete the week 9 follow-up 
visit and enter the open-label safety extension study TV50717-CNS-30047, or complete week 10
follow-up visit, or terminate early from the study.  Unless otherwise specified, the analysis includes all 
data collected in the database through the time of the database lock.  
An independent Data Monitoring Committee (IDMC) will review descriptive summaries of accumulating 
safety and subject disposition at a frequency recommended by the IDMC. Further description of the IDMC 
analyses can be found in the IDMC charter Version 1.0 dated 01 Feb 2018.

Study Objectives
The purpose of the study is to determine whether TEV-50717 is effective in the treatment of tics 
associated with TS in male and female patients between 6 and 16 years of age.
Primary Estimand
The primary estimand is the difference in means between TEV-50717 high dose and placebo for the 
change in the Total Tic Score (TTS) of the Yale Global Tic Severity Scale (YGTSS) from baseline to week 
8, in the target patient population of children and adolescents with TS who receive at least 1 dose of IMP 
and have both a baseline and at least 1 post-baseline YGTSS assessment, regardless of whether or not 
dose reduction, suspension, or treatment discontinuation occurred, and regardless of treatment-related 
adverse events. For the intercurrent event of study discontinuation, all data collected until time of study
discontinuation will be included and a missing at random (MAR) assumption will be hypothesized.
The primary estimand assesses the effectiveness in the reduction of motor and phonic tics associated 
with TS, focusing on the causal effects attributable to the investigational medicinal product (IMP).
Secondary Estimands 
The secondary estimands are: 
(1) the difference in means between TEV-50717 high dose and placebo for the change in the Tourette 
Syndrome - Clinical Global Impression (TS-CGI) score from baseline to week 8;
(2) the difference in means between TEV-50717 low dose and placebo for the change in the TTS of the 
YGTSS from baseline to week 8;
(3) the difference in means between TEV-50717 low dose and placebo for the change in the TS-GCI 
score from baseline to week 8;
(4) the difference in means between TEV-50717 high dose and placebo for the change in the Tourette 
Syndrome - Patient Global Impression of Impact (TS-PGII) score from baseline to week 8;
(5) the difference in means between TEV-50717 low dose and placebo for the change in the TS-PGII 
score from baseline to week 8;
(6) the difference in means between TEV-50717 high dose and placebo for the change in the Child and 
Adolescent Gilles de la Tourette Syndrome - Quality of Life (C&A-GTS-QOL) activities of daily living 
(ADL) subscale score from baseline to week 8;
(7) the difference in means between TEV-50717 low dose and placebo for the change in the C&A-GTS-
QOL ADL subscale score from baseline to week 8,
in the target patient population of children and adolescents with TS who receive at least 1 dose of IMP 
and have both a baseline and at least 1 post-baseline YGTSS assessment, regardless of whether or not 
dose reduction, suspension, or treatment discontinuation occurred, and regardless of treatment-related 
adverse events. For the intercurrent event of study discontinuation, all data collected until time of study
discontinuation will be included and a missing at random (MAR) assumption will be hypothesized.
The secondary estimands assess the effectiveness of TEV-50717 high dose and TEV-50717 low dose in 
the reduction of motor and phonic tics associated with TS and the impact of the reduction in tics on the 
patients’ quality of life as assessed by the clinicians and the patients, focusing on the causal effects 
attributable to the investigational medicinal product (IMP).

Primary and Secondary Objectives
Primary Objective
The primary objective of this study is to evaluate the efficacy of fixed doses of TEV-50717 to reduce 
motor and phonic tics associated with Tourette syndrome (TS). 
Secondary Objective(s)
The secondary objective of the study is to evaluate the safety and tolerability of TEV-50717.
Brief Description
This is a Phase 3, randomized, double-blind, placebo-controlled, 8-week treatment study in which 
patients with tics associated with TS will be invited to participate. Patients will be randomized to low-dose 
TEV-50717, high-dose TEV-50717, or placebo (1:1:1). 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 overall treatment period will be 8 weeks in duration, including an escalation period of 4 weeks, a 
maintenance period of 4 weeks, followed by a washout period of 1 week. 
Patients who complete the study may be eligible to begin participation in an open-label safety extension 
study of TEV-50717 (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 Investigational Medicinal Product (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. Patients not participating in the open-label safety extension study for TEV-50717 will have a 
follow-up telephone contact for safety evaluation 1 week after the end of the treatment period (2 weeks 
after their last dose of IMP).
Patient Selection
Inclusion Criteria
Refer to Protocol Section 4.1 for inclusion criteria.
Exclusion Criteria
Refer to Protocol Section 4.2 for exclusion criteria. 
Determination of Sample Size
It is estimated that approximately 50 patients per arm will enable a power of at least 90% to detect a 
beneficial effect of 6.5 points or more in the change from baseline to week 8 in TTS when the high-dose 
TEV-50717 arm is compared to placebo, assuming a standard deviation of 9.5 and a 2-sided type I error 
rate of 5% after accounting for dropouts.
Treatment Assignment & Blinding
This is a Phase 3, randomized, double-blind, placebo-controlled, 8-week-treatment study in which 
patients with tics associated with TS will be invited to participate. Patients will be randomized to either

TEV-50717 (low-dose, high-dose) or matching placebo in a 1:1:1 ratio using an Interactive Response 
Technology (IRT) based on their baseline weight and CYP impairment status. The patients will be 
stratified into 2 age groups (6- to 11-years and 12- to 16-years). Patients and investigators will remain 
blinded to treatment assignment during the study.
Treatment Assignment
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.
The randomization list and treatment will be assigned to the relevant treatment groups through a qualified 
service provider, i.e., 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.
Blinding
Patient randomization codes will be maintained in a secure access restricted folder on shared drive 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.
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.
Pharmacokinetic data may be assessed during the study. 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 (i.e., a dummy patient identifier will be 
linked to an individual patient’s concentration data). 
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 drug 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. 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). 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), 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 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.
Syneos Health 3910.00 describes the procedures for planning and conducting unblinded analyses prior to 
database lock for IDMC. Unblinded data, including randomization codes, type of dispensed kits and all 
subsequent SDTM, ADaM datasets, and analysis results generated from the unblinding information, will 
be stored under a pre-specified secure area with restricted access. Access to the unblinded folders can 
only be requested by a manager level or higher within the associate’s department. All relevant personnel 
to receive unblinded data will be identified and their responsibilities documented on the unblinded 
personnel form. The secure area for storage of data and results (including any report and its appendices) 
will be maintained so that it can be accessed only by unblinded personnel. All staff involved in the 
conduct of the trial shall remain ignorant of the results of all unblinded analyses. 
Administration of Study Medication
Investigational medicinal product will be administered as follows:

IMP should be swallowed whole and taken with food (e.g., 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 1.

To preserve blinding, 2 tablets will be taken twice daily starting at day 1 per Table 1. Daily 
doses will be administered twice daily, approximately 8 to 10 hours apart during the day. 
Depending on the dose and arm assigned, TEV-50717 tablets and/or placebo tablets will be 
taken to maintain the blind. 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.

The dose of IMP will be escalated weekly during the escalation period, according to Table 1.

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 escalation period, the dose of the IMP will be adjusted weekly according to 
Table 1 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.

a The baseline visit (day 1) will occur the same day as the scheduled first dose of the IMP (day 1).
b Assessment will be performed at the end of study week (±3 days). 
c For patients who withdraw prematurely, an early termination visit should be conducted as soon as possible after the last dose of IMP. In addition, 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 10. 
d 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 for TEV-50717. 
e The screening visit may be conducted over 2 separate visits at the discretion of the investigator.
f 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 8 visit 
should be recorded in the diary by the patient or parent/legal guardian. The site will document the date and time of the sample collection. Prior to the clinic visit 
on week 8, patients will be reminded to record the start time of their last meal and the time of their last dose in their diary.
g Dose escalation will only occur during the dose escalation period (i.e., from week 1 to week 3).
h Weight must be measured with shoes and outerwear off.
i Orthostatic blood pressure and pulse will be measured after patient is in standing position for at least 3 minutes.
j Assessment will be completed at investigator’s discretion.
k All ECGs will be performed after at least 5 minutes of 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 within 2 to 3 hours after the first 
PK sample collection. Patients with early morning visits (ie, within 2 hours of their scheduled AM dosing) should take their IMP dose in the clinic after the first PK 
sample is collected.

m The patient’s genotype for CYP2D6 will be blinded during the conduct of the study, except for the sample analysis and IRT vendor.
n For females who are postmenarchal or ≥12 years of age, a urine test will be administered at baseline and at week 4, while a serum test will be administered at 
screening, week 8, and if clinically indicated.
o 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).
p Children 6 years of age at baseline will not complete the self-report version; the parent/legal guardian will complete the parent version.
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 Input from the caregiver/adult is required.
s The YGTSS, TS-CGI, TS-PGII, and TS-PGIS questionnaires should be performed before any blood draws or ECG assessments.
t 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).
u Perform the Severity Ratings of OCD symptoms (Questions 1 through 10) only. Checklist does not need to be performed.
v Study drug 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 during 
escalation. See Table 1 for baseline weight-based dosing titration. At week 4, patients will receive doses for 4 weeks of treatment.
w The site needs to discuss the drug status during the telephone contacts to ensure that the patient has adequate tablets, inform the patient if they should 
escalate, and remind them to bring completed blister packs to the next in-clinic visit.

Analysis Sets
Screened Analysis Set
The screened analysis set will include all patients who are screened and have informed consent. This set 
will be used for patient listing and summary of patient disposition.
Intent-to-Treat Analysis Set
The intent-to-treat (ITT) analysis set will include all randomized patients, regardless of whether or not a 
patient took any IMP. In this population, treatment will be assigned based on the treatment to which 
patients were randomized, regardless of which treatment they actually received. 
The ITT analysis set will be used for all study population summaries, unless otherwise noted.  Summaries 
will be presented by treatment group and for all patients. Patients listing on efficacy data will be based on 
ITT analysis set.
Safety Analysis Set
The safety analysis set will include all randomized patients who receive at least 1 dose of IMP. In this the 
safety analysis set, treatment will be assigned based upon the treatment patients actually receive, 
regardless of the treatment to which they were randomized, unless otherwise specifed.
All safety analyses and listings will be based on the safety analysis set.
Modified Intent-to-Treat Analysis Set
The modified intent-to-treat (mITT) analysis set will include a subset of the ITT analysis set including only 
patients who receive at least 1 dose of IMP and who have both a baseline and at least 1 post-baseline 
YGTSS assessment. In the mITT analysis set, treatment will be assigned based on the treatment to which 
patients were randomized, regardless of which treatment they actually received. 
All efficacy analyses will be based on the mITT analysis set.
Per-Protocol Analysis Set
The per-protocol (PP) analysis set will include patients who are compliant with study medication (80% to 
105%), have a YGTSS assessment at baseline and at weeks 2, 4, and 8, and 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. Protocol deviations will be captured 
during the study conduct. Protocol deviations will be classified as major or minor prior to database lock. 
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 exclusion from PP analysis set will be 
reviewed in the blinded data review meeting (BDRM) before database lock.
Major Protocol Deviations Results in Exclusion from Analysis Set
Some of the examples of major deviations that may result in patient or visit exclusion from any analysis 
set are given in Table 3.

General Aspects for Statistical Analysis
General Methods
Statistical methodology and analyses are in accordance with the principles outlined by the ICH E9 
guidelines.  All statistical analyses will be conducted using SAS statistical software version 9.3 or above. 
Tables, listings and figures (TLFs) will be produced in accordance with the principles outlined by the ICH 
E3 guidelines. For most summary statistics, data will be analyzed by the following treatment groups:  
TEV-50717 High-Dose; TEV-50717 Low-Dose; Placebo. Total column will be included in all non-efficacy 
tables.
Data summaries will use descriptive statistics (number of patients [n], mean, standard deviation [SD], 
standard error [SE], median, minimum, and maximum) for continuous variables, and frequency and 
percentage of patients for categorical and ordinal variables, unless otherwise specified. For continuous 
variables, if n<5 then only median, min and max will be presented. 
Unless otherwise specified, all statistical tests will be two-tailed using a 0.05 level of significance. All 
confidence intervals (CIs) will be two sided 95% CIs.
Only visits mapped to scheduled visits will be included in by-visit summaries.  All visit assessment data 
will be included in shift tables and will appear in the patient listings.
Key Definitions
Baseline Values
Baseline is defined as the last non-missing measurement on or prior to the first dose of double-blind IMP.  
First Dose Date
The first dose date will be the date that the first dose of randomized, double-blind IMP is administered. 
Dose starting and stopping dates are collected on CRF per blister per week. The first dose date will be 
derived as the earliest date obtained from CRF. 
Last Dose Date
Last dose date is defined as the last dose stopping date. It will be derived as the latest dose stopping 
date obtained from CRF.
Study Day
Study Day is the number of days starting from the first administration of IMP, which is counted as Study 
Day 1.  If the assessment date is after the date of the first double-blind medication, the study day is 
calculated as date of assessment - date of the first dose administration+1.  If the assessment date is prior 
to the date of the first double-blind medication, the study day is calculated as date of assessment - date of 
the first dose administration.
Duration
Duration of double-blind treatment will be determined as: 
Duration = last dose date - first dose date + 1.

Missing Data
The handling of missing or incomplete data is described for each endpoint and data type (as needed) in 
Sections 8 to 9. In general, no data imputation will be applied for missing values in safety analysis. Data 
imputation method for efficacy analysis will be described in Section 8.

After mapping the data to the analysis visits of unscheduled and early termination visits, the following 
rules will apply unless other handling is specified for a particular analysis. 

If there is scheduled visit in the analysis window, scheduled visit will be selected.

If there is no scheduled visit, but early termination visit, early termination visit will be selected. 

If there are no scheduled or early termination visits, the unscheduled visit will be selected. If there are 
multiple unscheduled visits, the following rules will be used in sequential order:
o
The record closest to the planned assessment day will be selected for analysis.

o
If 2 records are equidistant from the scheduled day, then the later record will be selected. 

If a patient has no scheduled record or early termination/unscheduled visits in an analysis window, 
the patient will be considered missing at that visit.
For these analyses performed by time period, e.g. adverse events, the following definitions will be used:

Escalation Period - from the first dose of treatment until the day before the week 4 visit. For patients 
discontinued before the week 4 visit, the Escalation Period is until the later of the last dose of 
treatment and the early termination visit. 

Maintenance Period - from the day of the week 4 visit until the day of the week 8 visit. If a patient
enters the Maintenance Period but discontinues treatment early, the Maintenance Period is until the 
later of the last dose of treatment and the early termination visit. 

Follow-up Period - from the end of the Maintenance Period through the end of the study.

Overall Period - includes the Escalation Period, the Maintenance Periods, and the Follow-up Period, if 
applicable.
If the AE onset date is partial and can be potentially counted in multiple periods, AE will be included with 
the earliest period. 
Pooling of Centres
Patients will not be pooled based on site size, but rather by region, to ensure a sufficient number of 
patients per treatment arm in the ITT, mITT and PP sets for analysis that contain region as a model effect. 
The tables below show which countries comprise each of the regions to be used in analysis.

Demographic, Other Baseline Characteristics and Prior Medications
Patient Disposition and Withdrawals
Patient screened and patients screened but not in the ITT analysis set will be summarized only for all 
patients in screened analysis set using patient counts. Patients in the ITT analysis set, patients in the ITT 
analysis set but not treated, patients in safety, mITT, and PP analysis sets, patients who complete 
titration period, complete maintenance period, complete the study, complete the follow-up, and patients 
who withdraw from the study (and reason for withdrawing) during each treatment period will be 
summarized using descriptive statistics. The ITT analysis set will be used as the denominator for 
calculating percentages. 
If more than 15% of the patients withdraw from the study during the treatment period, the number of days 
until study discontinuation will be plotted using Kaplan-Meier methodology using the ITT analysis set 
(defined in section 5.3). Patients who complete the study treatment period will be censored on the study 
day of the last dose. 
A listing of study completion will be provided for all screened patients. A listing for analysis dataset with 
reason patient is excluded from the analysis set will also be provided for all patients in ITT analysis set.
In addition, the major protocol deviations will be summarized for ITT analysis set.
Demographic and Other Baseline Characteristics
Patient demographics and baseline characteristics will be examined to assess the comparability of the 
treatment groups. BMI will be computed as:
BMI (kg/m2) = Weight at baseline (kg)/[Height at screening (m)2].
In addition, normal age and sex-based z-scores and percentiles for BMI will be determined using the 
WHO growth charts. Age and sex-based BMI categories includes: Underweight (< 5 percentile), Normal 
(≥ 5 - < 85 percentile), Overweight (≥ 85 - < 95 percentile), Obese (≥ 95 percentile).
The continuous variables of patient age, weight, height, body mass index (BMI), BMI World Health 
Organization (WHO) adjusted z-scores and percentile, will be summarized using descriptive statistics. 
The categorical variables of patient sex, race, ethnicity, and BMI categories will be summarized using 
descriptive statistics for each category. Missing categories will be presented if necessary. For randomized 
patients, age at baseline will be used. 
The continuous variables of time since Tourette syndrome diagnosis in years and baseline TTS of the 
YGTSS will be summarized using descriptive statistics. The categorical variables of age group at baseline 
(6 to 11 years, 12 to 16 years), use of a strong CYP2D6 inhibitor (Yes/No), CYP2D6 genotype (Poor 
CYP2D6 metabolizer/ Non-poor CYP2D6 metabolizer), and CYP2D6 impairment status (Impaired/Not 
impaired) will be summarized using descriptive statistics for each category.
Strong CYP2D6 inhibitor status is determined by classifying patients as taking versus not taking a strong 
CYP2D6 inhibitor (i.e. paroxetine, fluoxetine, or bupropion), collected at screening from site. Impaired 
CYP2D6 function is defined as use of a strong CYP2D6 inhibitor at baseline or a poor CYP2D6 
metabolizer. Both CYP2D6 genotype and impairment status will be blinded during the study.

Other Therapies 
Prior non-pharmacological treatment will be collected in CRF. Type of treatment/procedure and indication 
will be listed.
Prior treatment given for TS will be summarized. The table will include number of patients with previous 
treatment given for TS, total duration of treatment, and best response to treatment. For an ongoing 
treatment, date of informed consent will be used to compute duration. If the start date is partial with year 
and month, 1st will be imputed. If the start date has only year, Jan, 1st will be imputed. If the end date is 
partial, the latest possible date on or before informed consent date will be imputed. If there are multiple 
prior treatments, the duration will be computed as the sum of all non-overlapping treatments. For 
overlapping treatments, the duration will be from the earliest treatment start date to the latest treatment 
end date.

Efficacy
The mITT analysis set will be used for all efficacy analyses, unless otherwise noted. Analyses and 
summaries will be presented by treatment group.
Week 9 efficacy data will be summarized but will not be included in any statistical analyses.
Efficacy Assessment and Time Points
Yale Global Tic Severity Scale (YGTSS)
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 YGTSS is composed of 11 items: 5 items for motor tic severity, 5 items for vocal tic severity, and 1 
item for impairment. Each item for motor tic severity and vocal is rated on a 6-point scale (0 for none to 5 
to severe). The MTSS is the sum of the 5 items for motor tic severity and the VTSS is the sum of the 5 
items for vocal tic severity. The TTS is the sum of the MTSS and the VTSS. The impairment score ranges 
from 0 (none) to 50 (severe). The GSS is the sum of the TTS and the impairment score.  
YGTSS is administered at screening; baseline; and weeks 2, 4, 8, and 9. 
For YGTSS, if a response to 1 item is missing within the MTSS or VTSS subscale, the missing response 
will be replaced with the average of the remaining responses within the subscale; if responses to 2 or 
more items within a subscale are missing, the missing responses will not be replaced and the subscale 
score will be set to missing; if at least 1 subscale is missing then the TTS will be set to missing. If the TTS 
or impairment score are missing, then the GSS will be set to missing. 
Tourette Syndrome-Clinical Global Impression (TS-CGI) 
The TS-CGI is administered at baseline and at weeks 2, 4, 8, and 9. 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).
Tourette Syndrome-Patient Global Impression of Impact (TS-PGII) 
The TS-PGII is administered at baseline and weeks 2, 4, 8, and 9. Input from the caregiver/adult is 
permitted.
The TS-PGII is a single-item questionnaire that asks the patient to assess the degree of impact due to 
current tics. The TS-PGII uses a 5-point scale, ranging from not at all (1) to very much (5), to assess 
overall response to therapy. In general, patient-rated global measures of change have face validity and 
have been shown to correlate with disability for a number of chronic conditions.
Child and Adolescent Gilles de la Tourette Syndrome – Quality of Life (C&A-GTS QOL) 
The C&A-GTS-QOL is administered at baseline, week 4, and week 8. 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). Following are the questions assessed in each C&A-GTS-QOL subscale:

Cognitive (questions 11, 12, 13, 14, 18, 20, 21, 23) (range: 0- 32)

Psychological (questions 15, 16, 17, 19, 25, 27) (range: 0 – 24)

Obsessive-compulsive (questions 7, 8, 9, 10) (range: 0 – 16)

Physical (questions 1, 3, 4) (range: 0 – 12)

Coprophenomena (questions 5, 6, 22) (range: 0 -12)

ADL (questions 2, 24, 26) (range: 0-12)
Scores for the six subscales are generated by summing items and, for ease of interpretation, 
transformation to a range of 0 to 100 (100x [(observed score - min possible score)/(max possible score -
min possible score)]). The total score, resulting from the sum of the subscale scores, is also normalized to 
a 0–100 range. For C&A-GTS-QOL, if a response to 1 question is missing within the subscale, the 
missing response will be replaced with the average of the remaining responses within the subscale; if 
responses to 2 or more questions within a subscale are missing, the missing responses will not be 
replaced and the subscale score will be set to missing; if at least 1 subscale is missing then the total 
score will be set to missing. For all analysis and summary, transformed scores will be used.

Primary Efficacy Endpoint and Analysis
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 (3 levels: weeks 2, 4, 
and 8), and the treatment group by week interaction. The baseline TTS, region, and age group at 
baseline (2 levels: 6-11 year, 12-16 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 Kenward-Roger approximation 
will be used to estimate denominator degrees of freedom.
The least squares means of the change in TTS from baseline at week 8 will be compared (primary: 
TEV-50717 high-dose arm vs. the placebo arm; secondary: TEV-50717 low-dose arm vs. the placebo 
arm) using 2-sided tests at the alpha=0.05 level of significance. The SAS code for this test is as follows:
 
   
   
   
   
 
The least square (LS) mean and standard error for the treatment groups, and the LS mean difference, 
95% confidence interval (CI), and p-value for each comparison (TEV-50717 high-dose vs. placebo at 
week 8; TEV-50717 low-dose vs. placebo at week 8) will be presented.
Cohen’s d effect size will also be computed for each comparison (Kelley, 2007). Cohen’s d is calculated 
as:
d = (μt – μp) / (pooled SD),
where µt represents the least-square (LS) mean of the specified TEV-50717 group (High- or Low-dose, 
µp is the LS mean of the placebo group, and the pooled SD is based on the adjusted LS means and 
adjusted standard errors from the mixed-effect model for MMRM, specifically: 


 1
 + 1

and nt=number of patients in specified TEV-50717 group and np=number of patients in placebo group.
The utility of Cohen’s d is to help judge the clinical importance of a measured treatment difference.
Sensitivity Analysis
The primary efficacy analysis on change in the TTS at Week 8 is to use MMRM model, described in 
Section 8.2.1 (the primary analysis model), using all observed data in the mITT anlaysis set. Data from 
patients that had dose reduction, suspension, treatment discontinuation, or treatment-related adverse 
events were collected in the study and will be included in the analyses, as these patients are generally

not excluded from the mITT analysis set. This model is appropriate when data isMAR. This approach is 
considered reasonable under the assumption that the percent of early terminations will be low. As of 12 
Dec 2019 the overall early termination rate from study 30060 was 8%, which is regarded to be in line with 
this assumption. Therefore, the proposed analysis is suitable for the primary estimand.
To assess the robustness of the primary efficacy analysis, the following additional analyses will include:

Change in the C&A-GTS-QOL ADL subscale from baseline to week 8 between low-dose 
TEV-50717-treated patients and placebo-treated patients.
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. 
Secondary efficacy analyses will be based on mITT analysis set. 
Secondary Efficacy Analysis
8.3.1.1.
Analysis of the change in the TS-CGI from baseline to Week 8
The change in the TS-CGI score from baseline to Week 8 (1st and 3rd secondary endpoints) will be 
analyzed in the same fashion as the primary analysis in Section 8.2.1, with the exception that the 
baseline value of the given endpoint will be included as the covariate.
8.3.1.2.
Analysis of the change in the TTS of YGTSS between low-dose TEV-50717-treated patients
and placebo-treated patients

Safety
The 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 Children’s Depression Inventory, Second 
Edition (CDI-2), Parent and Self-report Profiles
•
Observed values in the Children’s Columbia-Suicide Severity Rating Scale (C-SSRS)
•
Observed values in electrocardiogram (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)
The safety analysis set will be used for all safety analyses. Summaries will be presented by treatment 
group and for all patients.
Extent of Exposure
Duration of exposure to study drug (days) for individual patients is the number of days patient received 
drug (last day of study drug – first day of study drug + 1).  Duration of treatment (days) will be 
summarized using descriptive statistics. Weeks on treatment using the categories ≤2 weeks, >2 to ≤4 
weeks, >4 to ≤6 weeks, >6 to ≤8 weeks, and >8 weeks will also be summarized using descriptive 
statistics.  
Treatment Compliance 
Study drug administration will be included in the CRF. In the form, med ID (ID for blister pack), week 
range, dosing start and stop date, and number of pills taken from the blister pack are collected. Treatment 
compliance (%) is calculated as 100*(total number of pills taken / number of tablets expected to be used). 
The total number of pills taken is the sum of pills taken from all bottles dispensed, identified by med ID. If 
a patient does not return a pill bottle, it will be assumed that the patient took no study drug from that bottle 
for the purposes of calculating compliance. The number of pills expected to be used is based on the 
number of morning and evening dosing times during the treatment period (2 pills are used for each dosing 
time point).  A patient will be deemed compliant over the treatment period if the patient has taken 80% to 
105% of the expected tablets of study drug. 
Treatment compliance (%) will be summarized as continuous data using descriptive statistics. In addition, 
treatment compliance will be summarized as categorical data using descriptive statistics for the following 
categories:  <80%, 80% to 105%, >105%.
Concomitant Medication
A concomitant medication is 1)any medication that starts prior to first day of study drug administration and 
continues into treatment period; or 2) any medication that starts on or after the first dose of IMP and 
before the last dose of IMP. Concomitant medication will be summarized separately for 1) and 2). In the

case of completely missing stop date and medication is not ongoing, medication will be assumed to be 
concomitant. Medication cannot be considered as both prior and concomitant.
Concomitant medication summaries based on ATC level 3 and the preferred drug names will be produced 
for the safety analysis set. The summaries will present, by treatment group, the frequency and 
percentage of patients who used any medication in an ATC class, or any medication based on a single 
preferred drug name. Medication summaries will be sorted by descending total frequency of ATC class 
and by PT within ATC class. Patients will be counted only once for each medication class and each 
preferred drug name.
In addition, ADHD and antidepressant (see Section 7.4.1 for ATC code list) change will be summarized 
for:

Proportion of patients requiring new medication; 

Proportion of patients requiring increased medication; 

Proportion of patients requiring decreased medication; 

Proportion of patients discontinued medication;

Proportion of patients with medication switch.
Adverse Events 
Adverse events will be collected and recorded from the time a patient signs the informed consent to the 
end of 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. 
For all AEs, preferred AE terms and system organ class (SOC) will be coded using terminology from the 
Medical Dictionary for Regulatory Activities (MedDRA), version 20.1 or higher.
A treatment emergent adverse event (TEAE) is defined as an AE that begins after the first administration 
of study medication or existing AEs that worsen after the first dose of study medication.  All reported AEs 
will be listed, but only TEAEs will be summarized in tables. 
Drug related AEs will be considered those to be reasonable possibility based on the investigators 
assessment.  Missing relationship will considered as “Related”.  
Unless otherwise specified, AEs will be summarized by SOC and PT, with SOCs and PTs within SOCs 
presented in descending order of patient incidence. 
AE summary tables are listed below:

An overall summary of the number and percentage of patients reporting any TEAEs, serious 
TEAEs, treatment-related TEAEs, serious treatment-related TEAE, any TEAEs leading to study 
drug discontinuation, any TEAEs leading to patient study drug interruption, and TEAEs leading to 
death. The overall summary will also be prepared by age group (6-11 years, or 12-16 years);

TEAEs overall and by SOC and PT;

TEAEs by severity, overall and by SOC and PT. Missing severity, if any, will be assumed as 
“severe”;

Serious TEAEs, overall and by SOC and PT;

For summary tables, patients having more than 1 event with the same PT will be counted once for that 
term.  Patients having more than 1 event with the same SOC will be counted once for each event and
once for that SOC. For tabulations by severity, only a patient’s most severe event within the category 
(e.g. overall, SOC, PT) will be counted; similarly, for tabulations by relationship, only a patient’s most 
related event within a category will be counted.  Summaries will be presented by treatment group and for 
all patients. The denominator for percentages will be the number of patients in safety analysis set for the 
given treatment group (i.e., the N’s for the columns). Summary of all TEAEs will be presented in the 
overall period (escalation plus maintenance phase plus follow-up period) and for the escalation period, 
maintenance period, and follow-up period. By period summary will be based on the period the AE 
occurred (Section 6.4). Same type of AE may be counted in multiple periods in cases below:

AE resolved in the same period and reoccurred in a new period.

AE increased severity in another period.
Same AE will be counted only once in summary in the overall period. 
All adverse events in the overall treatment period will be summarized by CYP2D6 impairment status 
(Impaired/Not impaired). In addition, serious AEs and AEs by severity will be summarized by CYP2D6 
impairment status.
Listings will be provided for all AEs and the following subsets:


Vital Signs 
Vital signs will be measured at screening, baseline, and weeks 2, 4, 8, and 9. Measurements of vital signs 
will include measurement of pulse, blood pressure (BP), weight, body temperature, and respiratory rate. 
Pulse and BP in supine or semi-erect/seated position will be measured in each scheduled or unscheduled 
visits. In addition, standing BP and pulse will be taken at baseline, weeks 4, and 8. BMI will be computed 
similarly as in Section 7.2 at Week 8 and early termination visits. Weight and height at the visit will be 
used. Normal age and sex-based z-scores, percentiles for BMI, and BMI categories will also be 
determined using the WHO growth charts similarly as in Section 7.2. 
Orthostatic systolic and diastolic BP and pulse will be calculated as supine or semi-erect/seated 
measurement – standing measurement. Orthostatic hypotension (determined by blood pressure 
measurements only) is defined as having either a ≥ 20 mmHg reduction from supine to standing position 
in systolic blood pressure (SBP) or ≥ 10 mmHg reduction from supine to standing position in diastolic 
blood pressure (DBP) or both. Orthostatic tachycardia is defined as pulse increase ≥20 bpm from supine 
to standing position.
Observed values, change from baseline, for each vital sign parameter and position will be summarized at 
each visit by treatment and overall. 
In addition, orthostatic hypotension or orthostatic tachycardia occurrences, and the markedly abnormal 
post-baseline vital signs results will also be summarized for patients with at least one markedly abnormal 
value during the treatment period according to criteria specified in Table 5. A listing will be provided for all
markedly abnormal vital signs. A shift table for BMI age and sex adjusted categories will be presented 
comparing shifts from the baseline visit to week 8. Percentages will be based on the number of safety 
patients with a non-missing value for both the baseline and post-baseline visit for the given vital sign.

ECG
Assessment of Standard 12-lead ECG are obtained at screening, baseline, weeks 4 and 8.  A central 
ECG Standard 12-lead ECG will record heart rate (HR), PR interval, RR interval, QT interval, Frederica’s 
corrected QT interval (QTcF), and QRS duration. The overall ECG assessment will be centrally reported 
as “Normal” or “Abnormal” with respect to relevant abnormalities. If a post-baseline QTcF value 
>500 msec or change from baseline >60 msec is found, the investigator should repeat the ECG 
assessment twice. In this case, the confirmed QTcF, defined as the average of all 3 ECG values at the 
visit, will be used for summary. If ECG tests are repeated on the same day for any other reason per 
investigators discretion, the average of all ECG values on that day will be used for summary.

Children’s Depression Inventory, Second Edition (CDI-2)
The CDI-2 (parent and self-report versions) is administered at screening, baseline, and weeks 2, 4, 8, and 
9. 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 CDI-2 
Self-report version contains 6 subscales (emotional problem, negative mood/physical symptoms, negative 
self-esteem, functional problems, ineffectiveness, interpersonal problems). The raw score is the sum of all 
subscales scores, ranging from 0 to 56, with higher score indicating more severe depressive symptoms. 
The raw score is normalized to T-score (range: 40-90) based on patient’s age and gender.
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 CDI-2 
parent version contains 2 subscales (emotional problems and functional problem). The raw score is the 
sum of the 2 subscales, ranging from 0 to 51, with higher score indicating more depression-related 
behaviors observed in their children.
The CDI-2 parent version and self-report versions subscale scores, raw scores, and self-report version T 
scores will be presented at baseline and each visit each is measured.
Columbia-Suicide Severity Rating Scale (C-SSRS)
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 since last 
visit (SLV) scale is administered at baseline and at weeks 2, 4, 8, and 9. Patients will be placed into 
categories for suicidal ideation and for suicidal behavior based on their responses to various questions.
The suicidal ideation categories will be determined as follows by examining the response to the 5 
questions under Suicidal Ideation.

responses to Actual Attempt, Aborted Attempt, and Completed 
Suicide are No.
(8) Interrupted Attempt – if response to Interrupted Attempt is Yes 
and response to Aborted Attempt, and Completed Suicide are No.
(9) Actual Attempt – if response to Actual Attempt is Yes and 
Completed Suicide is No.
(10) Completed Suicide - if response to Completed Suicide is Yes
(0) None – if responses to all the above 4 questions are No. 
Suicidal ideation or behavior will be derived as the highest suicidal ideation or behavior score at the visit. 
Score of 0 represent “No Suicidal Ideation/Behavior”.
The frequency and percentage of suicidal ideation, suicidal behavior, suicidal ideation or behavior, and 
self-injurious behavior without suicidal intent will be summarized by treatment and overall, and visit. For 
baseline/screening version at baseline, past 2 years scores will be summarized.
Frequency and severity of suicidal ideation or behavior will also be summarized, using a shift table to 
examine changes in above C-SSRS scores from baseline compared to the worst (highest) category 
during the treatment period, by treatment and overall.
