1 PROTOCOL SUMMARY 
1.1 
Synopsis 
Sponsor Name: Cerevel Therapeutics, LLC 
Name of Investigational Medicinal Product: Tavapadon 
Protocol Title: A Phase 3, Double-Blind, Randomized, Placebo-Controlled, 
Parallel-Group, 27-Week Trial to Evaluate the Efficacy, Safety, and Tolerability of Two 
Fixed Doses of Tavapadon in Early Parkinson’s Disease (TEMPO-1 Trial) 
Short Title: Fixed-Dose Trial in Early Parkinson’s Disease 
IND Number: 118,647 
EudraCT Number: 2019-002949-38 
Trial Phase: 3 
Indication: Parkinson’s disease 
Rationale: Tavapadon (PF-06649751, CVL-751) is a partial agonist of the dopamine 
D1-like receptors (D1Rs), with high specificity for the D1 and D5 receptor subtypes 
(D1/D5), which is being developed as a treatment for Parkinson's disease (PD). The 
efficacy, safety, and tolerability of tavapadon in Phase 1b and 2 trials support its potential 
as the first partial agonist therapy in an important new dopamine receptor-selective 
mechanism for treatment of PD symptoms. By targeting the D1R subtype, tavapadon 
aims to improve motor control symptoms while minimizing adverse events (AEs) that 
may be mechanistically linked to D2/D3 dopamine receptor agonists (notably, 
dose-limiting hypotension, impulse control disorders, sleep disorders, and, potentially, 
some forms of hallucinations). This trial is designed to further define and confirm the 
magnitude of efficacy and the risk/benefit profile of tavapadon over the target dose range 
of 5 to 15 mg once daily (QD). 
Objectives and Endpoints:  
The objectives and efficacy, safety, and pharmacokinetic (PK) endpoints of the trial are 
summarized in Table 1.

Overall Design: 
This is a prospective, Phase 3, multicenter, multinational, randomized, double-blind, 
placebo-controlled, parallel-group, 27-week trial to evaluate the efficacy, safety, 
tolerability, and PK of 2 fixed doses of tavapadon (5 mg QD and 15 mg QD) in male and 
female subjects aged 40 to 80 years who have a diagnosis of PD (consistent with the UK 
Parkinson’s Disease Society Brain Bank diagnostic criteria); a modified Hoehn and Yahr 
stage of 1, 1.5, or 2; a Movement Disorder Society – Unified Parkinson’s Disease Rating 
Scale (MDS-UPDRS) Part II score ≥2 and Part III score ≥10; and are not receiving 
antiparkinsonian medication other than monoamine oxidase B (MAO-B) inhibitors. The 
trial will include a Screening Period (maximum of 4 weeks), a 27-week Treatment 
Period, and a 4-week Safety Follow-up Period.  
Each subject will participate in the trial for up to approximately 35 weeks, including 
screening (up to 4 weeks), treatment (27 weeks), and posttreatment safety follow-up 
(4 weeks). Subjects who complete through Week 27 of the trial may have the opportunity 
to enter an open-label extension trial (Protocol CVL-751-PD-004).  
A substudy to evaluate the effect of tavapadon on the QT interval using concentration-QT 
modelling is also included in this trial. Matched triplicate electrocardiograms (ECGs) and 
plasma tavapadon concentrations that are collected at preselected sites will be used to 
characterize the effects of tavapadon on the QT interval. 
Disclosure Statement: This is a parallel-group trial to evaluate the efficacy, safety, 
tolerability, and PK of 2 fixed doses of tavapadon (5 mg QD and 15 mg QD) and placebo 
in subjects with early PD. Treatment assignments will be blinded to the investigators and 
other trial site personnel, the subjects, and all sponsor personnel who are involved in the 
conduct of the trial (including trial monitoring, data management, and data analysis).  
Number of Subjects: A total of 522 subjects are planned to be randomized into 
3 treatment groups (174 subjects per treatment group). 
Key Entry Criteria: Male and female subjects aged 40 to 80 years who have a diagnosis 
of PD (consistent with the UK Parkinson’s Disease Society Brain Bank diagnostic 
criteria); a modified Hoehn and Yahr stage of 1, 1.5, or 2; an MDS-UPDRS Part II score 
≥2 and Part III score ≥10; and are not receiving antiparkinsonian medication other than 
MAO-B inhibitors will be enrolled.  
Intervention Groups, Trial Treatments, and Duration: Subjects will be randomized in 
a 1:1:1 ratio to receive tavapadon 5 mg QD, tavapadon 15 mg QD, or placebo QD. The 
dose of tavapadon will be titrated to a target dose using a fixed titration scheme. 
Randomization will be stratified by concurrent use of allowed PD medications (MAO-B 
inhibitors) during the Treatment Period. The planned duration of treatment is 27 weeks, 
including the Titration, Adjustment, and Maintenance Phases. The investigational 
medicinal products (IMPs) will be taken orally.

Statistical Methods 
Sample Size Estimation: A sample size of 174 subjects per group (total, 522 subjects) 
will provide at least 90% power to detect a change in the primary outcome measure 
(change from baseline in the MDS-UPDRS Parts II and III combined score) of 4 points, 
with a standard deviation of 9, 2-sided alpha level = 0.05, and assuming a 27% dropout 
rate. 
In the event of higher than anticipated early terminations due to COVID-19 or other 
reasons, Cerevel may extend enrollment in order to maintain the planned statistical 
power. 
Efficacy Analyses: The efficacy endpoints will be assessed for each of the 2 dose levels 
of tavapadon versus placebo. A hierarchical testing procedure with a prespecified order 
for the primary and key secondary endpoints will be used to control the Type I error rate 
at the 0.05 level (2-sided). Additional details will be provided in the statistical analysis 
plan.  
The primary efficacy endpoint (the change from baseline to endpoint in the 
MDS-UPDRS Parts II and III combined score) will be analyzed using a Mixed Model for 
Repeated Measures (MMRM). The change from baseline at each postbaseline timepoint 
will be included in the MMRM as repeated measures. The baseline score will be included 
as a covariate, and treatment group, visit, the interaction between treatment group and 
visit, and the stratification factor (concurrent use of MAO-B inhibitor; yes/no) will be 
included as fixed factors. An unstructured covariance structure will be utilized. The 
difference between each tavapadon dose level and placebo at endpoint will be estimated 
based on the least square means (LSMeans) from the MMRM. A hypothetical strategy 
will be used to address intercurrent events (ICEs) of potential death, treatment 
discontinuations, missed visits/assessments, and start of prohibited concomitant 
medications. The data after treatment discontinuations or after the start of prohibited 
concomitant medications will be censored under the hypothetical strategy. The missing 
values are assumed to be missing at random (MAR) in the primary analysis, including 
missing due to COVID-19 control measures. Sensitivity analyses will be performed to 
assess the impact of deviation from MAR assumptions on the analysis results. 
The key secondary endpoint of the change from baseline to endpoint in the MDS-UPDRS 
Part II score will be analyzed using an MMRM analysis similar to the analysis of the 
primary endpoint.  
The key secondary endpoint of the percentage of responders at endpoint, defined as a 
score of “much improved” or “very much improved” on the Patient Global Impression of 
Change (PGIC), will be analyzed using the SAS® GLIMMIX procedure for binomial data 
with logit link. This generalized linear mixed model analysis will include response data 
from each postbaseline visit as repeated measures with treatment group, visit, and 
interaction between treatment group and visit as fixed effects. An unstructured covariance 
structure will be used for the repeated measures. If the model fails to converge with the

2 INTRODUCTION 
2.1 
Trial Rationale 
Tavapadon (PF-06649751, CVL-751) is a partial agonist of the dopamine D1-like 
receptors (D1Rs), with high specificity for the D1 and D5 receptor subtypes (D1/D5), 
which is being developed as a treatment for Parkinson's disease (PD). Efforts to develop 
selective D1R agonists have been ongoing for decades, in part, because of their clear 
potential to produce robust efficacy through selective stimulation of the direct pathway. 
Mechanistic evidence also suggests that selective and partial activation of D1Rs may 
avoid some of the limiting side effects of the D2/3 agonist or dopamine replacement 
therapies. 
The efficacy, safety, and tolerability of tavapadon in Phase 1b and 2 trials support its 
potential as the first partial agonist therapy in an important new dopamine 
receptor-selective mechanism for treatment of PD symptoms. By targeting the D1R 
subtype, tavapadon aims to improve motor control symptoms while minimizing adverse 
events (AEs) that may be mechanistically linked to D2/D3 dopamine receptor agonists 
(notably, dose-limiting hypotension, impulse control disorders, sleep disorders, and, 
potentially, some forms of hallucinations). 
This prospective, Phase 3, multicenter, multinational, randomized, double-blind, 
placebo-controlled, parallel-group, 27-week trial will evaluate the efficacy, safety, 
tolerability and pharmacokinetics (PK) of 2 fixed doses of tavapadon (5 mg and 15 mg 
once daily [QD]) in subjects with early PD to further define and confirm the magnitude 
of efficacy and the risk/benefit profile of this specific target dose range. A substudy is 
also included in the main trial to characterize the relationship between tavapadon 
concentrations and the QT interval. 
2.2 
Background 
Parkinson’s disease is a chronic, progressive and disabling neurodegenerative disease. 
The number of individuals with PD aged 50 and older was between 4.1 and 4.6 million in 
2005 in the 10 most populous nations in the world* combined and is projected to double 
to between 8.7 and 9.3 million by 2030 (Dorsey et al, 2007). The incidence is 
approximately 20 per 100,000 persons per year, increases with advancing age (65 years 
and older) to up to >100 per 100,000 (Twelves et al, 2003), and is reported to be 1.4% at 
age 55 years and 4.3% at 85 years and older (de Rijk et al, 1995). 
The specific etiology of PD remains unclear, but there are continued advances in 
understanding the possible underlying mechanisms and causative factors. A more 
complete understanding of basal ganglia function, the neuropathologic and 
neurochemical abnormalities in PD, and genetic forms of parkinsonism provide hope that

disease-modifying therapeutic approaches can be identified. However, there remains 
significant current and future need for improved symptomatic therapies. 
It is generally recognized that the primary degeneration in PD involves basal ganglia and 
its projections. The underlying pathology indicates a loss of dopaminergic neurons in the 
substantia nigra, and neuronal loss in the locus coeruleus and the nucleus raphe. 
Dopamine acts on 5 receptor subtypes to facilitate controlled movement, and insufficient 
activation of these receptors is established as the primary cause of motor control deficits 
in PD. The dopamine receptor subtypes have distinct localization and primary signaling 
cascades and are commonly divided into 2 groups based on their function. The D1-like 
family includes the D1 and D5 subtypes, which are localized on a “direct” striatal motor 
control pathway and which stimulate cellular activity by increasing intracellular cyclic 
adenosine monophosphate (cAMP) levels. The D2-like family includes the D2, D3, and 
D4 subtypes, which are localized to an “indirect” motor control pathway and which 
decrease intracellular cAMP when activated. The degenerative character of the disease is 
accompanied by intracellular deposits of Lewy bodies and by microglia-activation. Basic 
research currently suggests that oxidative injury to specific neurons in the basal ganglia 
may be at least one of the underlying causes of “idiopathic parkinsonism,” apart from 
other factors, such as genetic changes. 
The major clinical diagnostic features of PD include tremor, rigidity of skeletal muscles, 
bradykinesia, impairment of postural reflexes (also referred to as parkinsonism), and gait 
disturbances. Additional symptoms include many other motor features and nonmotor 
features, including psychiatric, sensory, and autonomic changes. Patients may or may not 
require therapy in the early stages of PD, which typically presents with fewer and less 
severe symptoms, and may still be able to work. Unfortunately, disease progression is 
inevitable and, within 1 to 3 years of diagnosis, nearly all patients will require therapy. 
Continued disease progression, in conjunction with common medication-related side 
effects, usually leads to individualized optimization of therapy in an effort to manage the 
increasing symptoms and common medication-related side effects. Despite these efforts, 
a majority of patients experience significant worsening of symptoms and reduced quality 
of life and independence and will leave the workforce within 5 years of diagnosis 
(Jasinska-Myga et al, 2012). No proven disease-modifying treatments for PD are 
currently available. Management options for PD consist mainly of dopaminergic drugs 
and, in a limited number of patients, deep brain stimulation. 
Levodopa (L-Dopa, the metabolic precursor of dopamine) therapy provides increased 
dopamine levels in a transient and pulsatile fashion and affords rapid improvement of 
motor symptoms. However, prolonged use of L-Dopa leads to the development of motor 
complications in most patients. These include motor fluctuations, which are an 
alternation between “on” periods when motor symptoms are well controlled and “off” 
periods when motor symptoms are poorly controlled. An additional type of motor 
complication is the occurrence of dyskinesia or abnormal involuntary movements 
(Marconi et al, 1994; Vijayakumar and Jankovic, 2016). Troublesome motor 
complications from L-Dopa therapy can lead to substantial impairment, negative impacts 
on activities of daily living, and decreased quality of life.

Agents that preferentially activate the dopamine D2 and D3 receptor subtypes (D2/D3R), 
such as pramipexole, ropinirole, and rotigotine, are also approved for the symptomatic 
treatment of PD (Stocchi et al, 2016). These agents generally exhibit less frequent motor 
complications than L-Dopa but are not as effective for controlling motor symptoms 
(Connolly and Lang, 2014; Rizek et al, 2016; Dietrichs and Odin, 2017). 
D2/D3-preferring agonists are also associated with an increased incidence of specific 
adverse effects, including somnolence, hypotension, compulsive behaviors, and 
hallucinations, particularly in the elderly (Stowe et al, 2008). 
Selegiline, rasagiline, and safinamide are monoamine oxidase B (MAO-B) inhibitors, 
which block one pathway of dopamine degradation and improve motor symptoms of PD 
in some settings (Connolly and Lang, 2014; Binde et al, 2018). Of these, only rasagiline 
is approved in the United States and Europe as a monotherapy treatment, and available 
indirect evidence suggests that this class is less efficacious than D2/3 agonists (Stowe et 
al, 2008; Zhuo et al, 2017). 
Despite available treatment approaches, the chronic and progressive nature of PD 
continues to result in significant burden and impact on quality of life and day-to-day 
functioning for patients (Drutyte et al, 2014). There are significant unmet medical needs 
throughout the stages of PD, from improving motor control in patients with early-stage 
disease who have not yet begun dopamine replacement therapy, to increasing daily “on” 
time without troublesome dyskinesias while adequately controlling motor symptoms in 
patients with moderate-to-advanced disease who are receiving available therapies 
(patients with motor fluctuations). Patients and their families are anxious for testing of 
new therapeutic mechanisms that can provide strong and lasting control of the symptoms 
of PD and that can minimize some of the known side effects of existing therapeutic 
options, such as dose-limiting dyskinesias, daytime sleepiness, and impulsivity. 
Completed Phase 1b and 2 trials have demonstrated that tavapadon can provide improved 
control of motor symptoms in both early and more advanced stages of PD, with an 
acceptable safety profile. 
2.3 
Benefit/Risk Assessment 
In a Phase 1b trial in subjects with PD with motor fluctuations (Trial B7601009), 
increasing benefit on motor symptoms was observed with increased tavapadon dose, with 
magnitudes of change on the Movement Disorder Society – Unified Parkinson’s Disease 
Rating Scale (MDS-UPDRS) Part III scores well above the changes that are recognized 
as clinically meaningful (>3-point decrease from baseline; Horváth et al, 2015) and 
significantly better than for placebo. Sustained effects of tavapadon on tremor (as shown 
by the MDS-UPDRS Part III scores that were lower than at baseline for up to 12 hours 
after dosing) were also observed in a second Phase 1b trial in subjects with PD with 
motor fluctuations (Trial B7601005). 
In a Phase 2 trial of tavapadon in L-Dopa-treated subjects with PD who were 
experiencing motor fluctuations (Trial B7601003), analysis of the change from baseline 
in average daily “on” time without troublesome dyskinesia showed that the magnitude of

Version 4.0: 06 Jul 2023
 
 
benefit of tavapadon 15 mg QD, relative to placebo, was approximately 1 hour at 
Week 10. Although the difference from placebo did not achieve statistical significance 
due to the small sample size, this difference is considered clinically meaningful (Hauser 
et al, 2011; Hauser et al, 2014).  
Motor symptoms were significantly more improved with tavapadon monotherapy than 
with placebo in a Phase 2, placebo-controlled, 15-week, flexible-dose trial in subjects 
with early PD (Trial B7601011), as assessed by the change from baseline to Week 15 in 
the MDS-UPDRS Part III total score (least square mean [LSMean] change from 
baseline = -9.0 for tavapadon and -4.3 for placebo; difference from placebo = -4.8; 
p=0.041). The difference between tavapadon and placebo in the change from baseline to 
Week 15 in the MDS-UPDRS Parts II and III combined score was also statistically 
significant (LSMean change from baseline = -11.2 for tavapadon and -5.4 for placebo; 
difference from placebo: -5.9; p=0.020). The magnitude of the placebo-adjusted 
treatment difference in improvement from baseline in the MDS-UPDRS Part III score 
met the threshold for a clinically meaningful change (>3-point decrease from baseline; 
Horváth et al, 2015), as did the magnitude of the placebo-adjusted treatment difference in 
improvement from baseline in the MDS-UPDRS Parts II and III combined score 
(>4.9-point decrease from baseline; Makkos et al, 2018). 
The safety results across all clinical trials demonstrate that tavapadon was generally 
well tolerated up to a titrated dose of 15 mg QD in subjects with PD, either as 
monotherapy (early PD) or as adjunctive treatment with a stable dose of L-Dopa 
(advanced PD). A dose-dependent increase in the frequencies of nausea and headache 
was observed across all trials. Nausea, vomiting, dyskinesia, fall, fatigue, sleep disorder, 
and tremors were the most common AEs leading to discontinuation of tavapadon. The 
appearance of nausea, orthostatic blood pressure changes, and fatigue is often related to 
the speed of titration with dopamine receptor agonists (historically with D2 agents) and 
may be mitigated by a slower titration method. 
No notable differences in laboratory abnormalities, electrocardiogram (ECG) parameters, 
or suicidality assessments were observed between tavapadon and placebo. Multidose 
cohorts in Phase 1 trials in healthy volunteers and subjects with PD (including subjects 
with PD who were treated at doses of up to 25 mg QD of tavapadon) did not suggest that 
tavapadon prolonged the QT interval corrected for heart rate by Fridericia’s formula 
(QTcF). Trials of longer treatment duration suggest a tavapadon dose-related decrease 
from baseline in systolic and/or diastolic parameters, with some cases of asymptomatic 
hypotension. This finding is common with dopamine D2 agonists and is prevalent in the 
population of patients with PD whether treatment naïve or treated with L-Dopa. 
Taken together, the current data suggest an appropriate benefit-risk ratio for further 
evaluation of tavapadon in Phase 3 clinical trials at doses up to 15 mg QD. Additional 
information about the known and expected benefits, risks, and AEs of tavapadon is 
provided in the Investigator’s Brochure.

4 TRIAL DESIGN 
4.1 
Overall Design 
This is prospective, Phase 3, multicenter, multinational, randomized, double-blind, 
placebo-controlled, parallel-group, 27-week trial to evaluate the efficacy, safety, 
tolerability, and PK of 2 fixed doses of tavapadon (5 mg QD and 15 mg QD) in male and 
female subjects aged 40 to 80 years who have a diagnosis of PD (consistent with the UK 
Parkinson’s Disease Society Brain Bank diagnostic criteria); a modified Hoehn and Yahr 
stage of 1, 1.5, or 2; an MDS-UPDRS Part II score ≥2 and a Part III score ≥10; and are 
not receiving antiparkinsonian medication other than MAO-B inhibitors. The trial will 
include a Screening Period (maximum of 4 weeks), a 27-week Treatment Period, and a 
4-week Safety Follow-up Period (Figure 1). Each subject will participate in the trial for 
up to approximately 35 weeks.  
4.1.1 
Screening/Baseline Period 
Subjects who provide written informed consent will be screened for eligibility during the 
maximum 4-week Screening Period. Subjects who are confirmed to be eligible for the 
trial will be scheduled for a Baseline Visit within approximately 4 weeks after the 
Screening Visit. Subjects who continue to meet the eligibility criteria at the Baseline Visit 
will be randomized in a 1:1:1 ratio to 3 treatment groups: 
• 
Tavapadon 5 mg QD 
• 
Tavapadon 15 mg QD 
• 
Placebo QD 
Randomization will be stratified by concurrent use of allowed PD medications (MAO-B 
inhibitors) during the Treatment Period.

4.1.2 
Treatment Period 
The dose of tavapadon will be titrated to either 5 mg QD or 15 mg QD and then 
maintained for the duration of the 27-week Treatment Period. The titration schedule, as 
shown in Table 4, will be used for all subjects who are randomized to receive tavapadon. 
Subjects will take 3 tablets of investigational medicinal product (IMP), either all 
tavapadon tablets, all placebo tablets, or a combination of tavapadon and placebo tablets, 
throughout the trial to maintain the trial blind. 
Table 4 
Tavapadon and Placebo Dosing Schedule 
Abbreviation: QD = once daily. 
This titration scheme will be used for all subjects who are randomized to tavapadon. 
Subjects who are randomized to the tavapadon 5 mg QD treatment group will receive this 
dose from Day 41 until Day 189 (end of Week 27). The dose of tavapadon will continue 
to be titrated for subjects who are randomized to the tavapadon 15 mg QD treatment 
group; these subjects will receive 10 mg QD of tavapadon from Day 57 through Day 72 
and then 15 mg QD of tavapadon from Day 73 until Day 189 (end of Week 27). 
No deviations in the titration schedule up through 
 will be allowed. Titration of 
tavapadon should be guided by absence of tolerability issues that are reported as AEs and 
that are of sufficient severity resulting in significant dysfunction or distress to the subject. 
Any questions regarding tolerability issues and titration should be directed to the medical 
monitor before adjustments are initiated. Subjects who cannot achieve or tolerate the dose 
at 
 (5 mg QD) or 
 (10 mg QD) must be discontinued from the trial.  
Starting on Day 74, subjects who achieve but do not tolerate the dose at 
 may go 
back to the dose at 
 Subjects may remain at the 
dose or will be permitted a 
one-time rechallenge back to the 
 dose if needed for symptomatic control. 
Subjects must receive the 
 dose for at least 7 days before a rechallenge to the

Version 4.0: 06 Jul 2023
 
 
 dose is attempted. Subjects who are unable to tolerate the 
 dose upon 
rechallenge will be discontinued from the trial. 
The first dose of IMP will be taken at the trial site at the Baseline Visit; all other doses 
will be taken on an outpatient basis. Assessments will be conducted in the clinic, ~2 to 
~6 hours after the subjects have taken their daily dose of IMP (at home), at the end of 
Weeks 2, 5, 8, 11, 14, 18, 22, 26, and 27. Blood samples for PK will be collected after 
administration of the first dose on Day 1 (~1 hour after dosing) and at the Weeks 5, 11, 
14, 22, and 27 clinic visits. 
4.1.3 
Safety Follow-up Period 
Subjects who complete through Week 27 of the trial may have the opportunity to enter an 
open-label extension trial (Protocol CVL-751-PD-004). Subjects who are ineligible or 
elect not to enter the open label trial will be contacted by telephone at 4 weeks after 
discontinuation of IMP (either after completing the full 27-week Treatment Period or 
upon premature discontinuation from the trial). 
4.1.4 
Concentration-QT Substudy 
A substudy to evaluate the effect of tavapadon on the QT interval using C-QT modelling 
is also included in this trial. Matched triplicate ECGs and plasma tavapadon 
concentrations that are collected at preselected sites will be used to characterize the 
effects of tavapadon on the QT interval (see Section 10.7 [Appendix 7] for details). All 
other procedures will be the same as for the main trial. 
4.2 
Scientific Rationale for Trial Design 
The randomized, double-blind, placebo-controlled, parallel-group trial design is widely 
accepted as one that minimizes the risk of bias and that is appropriate for evaluating the 
effects of a trial treatment in indications in which use of a placebo is ethical (US FDA, 
2001). Randomization reduces bias in the assignment of subjects to a treatment group, the 
double-blind design prevents differential treatment and assessments, and the 
placebo-controlled design controls for all potential influences on the actual or apparent 
course of the disease other than those arising from the pharmacologic action of the drug. 
The MDS-UPDRS is a comprehensive assessment that is designed to monitor the burden 
and extent of PD across the longitudinal disease course and provides a clinical endpoint 
in therapy trials (Goetz et al, 2008). The primary endpoint, the change from baseline to 
endpoint in the MDS-UPDRS Parts II (motor aspects of experiences of daily living) and 
III (motor examination) combined score represents a clinically applicable outcome 
measure (Makkos et al, 2018). 
The key secondary efficacy endpoint of the percentage of responders at endpoint, defined 
as a score of “much improved” or “very much improved” on the Patient Global 
Impression of Change (PGIC), is an accepted measure of treatment response and is 
widely used in clinical trials as a patient-reported measurement of treatment success.

The safety endpoints, including physical and neurological examinations, vital signs, 
ECGs, laboratory evaluations, and AEs, are those commonly used to assess the safety and 
tolerability of trial treatments. The Questionnaire for Impulsive-Compulsive Disorders in 
Parkinson’s Disease Rating Scale (QUIP-RS) is a global screening instrument that 
assesses impulsive control disorders (ICDs) and related disorders (punding, hobbyism, 
and dopamine dysregulation syndrome) in patients with PD (Weintraub et al, 2012), and 
the Epworth Sleepiness Scale (ESS) is a scale that is intended to measure daytime 
sleepiness (Johns, 1991). The Columbia-Suicide Severity Rating Scale (C-SSRS) is 
commonly used for stringent monitoring of suicidality in clinical trials of neurological 
compounds (Posner et al, 2011).  
4.3 
Justification for Dose 
Patients with PD prioritize robust motor control as a key attribute of a desirable 
symptomatic therapeutic. In the small, Phase 2, flexible-dose, 15-week trial of tavapadon 
in early PD (Trial B7601011), subjects gradually increased their dose of tavapadon at 
weekly intervals, as tolerated, during the initial 9-week dose optimization period until 
their parkinsonian symptoms were optimally controlled. The target dose range was 3 to 
15 mg QD; however, a maintenance dose of <3 mg may have been selected, based on 
clinical response. Of the 26 subjects who were randomized to tavapadon and who reached 
the 6-week maintenance dosing phase, 73% required doses of 5 to 15 mg QD to achieve 
optimized motor control based on clinical judgement. Reduction from baseline in motor 
symptoms of >10 points on the MDS-UPDRS Part III score primarily occurred in 
subjects who received doses of >5 mg QD of tavapadon, with robust separation from 
placebo treatment achieved at doses >7 mg QD (-6.9 placebo-adjusted treatment 
difference), whereas a dose of 3 mg QD consistently produced reductions of <10 points 
from baseline on the MDS-UPDRS Part III score. These data suggest that doses <5 mg 
QD are unlikely to deliver clinically meaningful benefit over placebo in motor symptom 
control to most patients with PD. 
In a Phase 1 multiple-dose trial in subjects with PD (Trial B7601005), tavapadon 
exposure increased with an increase in dose over the dose range of 5 to 15 mg; however, 
the increase in mean area under the plasma concentration-time curve over the dosing 
interval (24 hours; AUCtau) and in mean maximum observed plasma concentration (Cmax) 
was less than dose proportional between the 15 and 25 mg doses. This is consistent with 
the known moderate-to-low solubility of tavapadon at the pH of the gastrointestinal track 
(pH 6.5), which likely limited absorption. Therefore, doses >15 mg are not likely to 
provide meaningful increases in tavapadon exposure and may eventually lead to an 
exposure plateau. In this same trial, doses of 25 mg QD produced markedly greater rates 
of gastrointestinal AEs as compared with doses of 15 mg QD. Nausea and vomiting were 
reported in 8 of 19 and 4 of 19, respectively, of the subjects who received 25 mg QD 
doses of tavapadon, whereas nausea and vomiting were reported in 3 of 11 and 1 of 11, 
respectively, of the subjects who received 15 mg QD doses of tavapadon. The safety and 
pharmacokinetic data from this Phase 1 trial suggest that doses >15 mg QD are unlikely 
to have an optimal risk/benefit profile for patients with PD.

Version 4.0: 06 Jul 2023
 
 
Taken together, these findings suggest that an optimal dose range of tavapadon for the 
treatment of PD may reasonably be between 5 and 15 mg QD for the individual patient, 
based on symptomatic needs and tolerability thresholds.

Screening Assessments 
20.  
Subjects with a MoCA score <26. 
21.  
Subjects with a supine blood pressure ≥160 mmHg (systolic) or ≥100 mmHg (diastolic) at 
screening. The average of two supine measurements will be used to assess eligibility. 
22.  
Subjects with clinically significant orthostatic hypotension (eg, syncope). 
23.  
Subjects with a 12-lead ECG demonstrating a QTcF interval >450 msec  
At screening: 
• 
If the QTcF interval is >450 msec on the machine reading, the ECG should be repeated 
with 2 additional recordings. Based on the QTcF intervals that are reported by the 
central service, a subject will be excluded if the QTcF interval is >450 msec on 2 or 
more of the 3 ECG recordings, unless due to ventricular pacing.  
 
At baseline: 
• 
If the QTcF interval is >450 msec on the machine readings, consult the medical monitor 
to determine whether the subject remains eligible to be randomized while awaiting the 
readings from the central service. 
24.  
Subjects with moderate or severe renal impairment (creatinine clearance as estimated by 
Cockcroft-Gault formula <30 mL/min or on dialysis). 
25.  
Subjects with any of the following abnormalities in clinical laboratory tests at the Screening 
Visit, as assessed by the central laboratory and confirmed by a single repeat measurement, if 
deemed necessary: 
• 
AST or ALT ≥3 × ULN. 
• 
Total bilirubin ≥1.5 × ULN. Subjects with a history of Gilbert's syndrome may be 
eligible provided they have a value <ULN for direct bilirubin. 
26.  
Subjects with other abnormal laboratory test results, vital sign results, or ECG findings unless, in 
the judgment of the investigator, the findings are not medically significant and would not impact 
the safety of the subjects or the interpretation of the trial results. The medical monitor should be 
contacted to discuss individual cases, as needed. Tests with exclusionary results should be 
repeated to ensure reproducibility of the abnormality before excluding a subject based on the 
criteria provided in the protocol. For medically significant or exclusory abnormal ECGs results, 2 
additional ECG recordings should be collected, to ensure reproducibility of the abnormality, and 
the 3 ECG recordings read by the central service to confirm the abnormality before excluding a 
subject. 
Other 
27.  
Subjects who previously participated in any tavapadon trial, including this trial, and received 
IMP. 
28.  
Subjects who received treatment with any other investigational drug within 60 days before 
signing the ICF. 
29.  
Any subject who, in the opinion of the sponsor, investigator, or medical monitor, should not 
participate in the trial.

subjects to meet the Consolidated Standards of Reporting Trials (CONSORT) publishing 
requirements and to respond to queries from regulatory authorities. Minimal information 
includes demography, screen failure details, and eligibility criteria. 
Individuals who do not meet the criteria for participation in this trial (screen failure) at 
screening may be rescreened once at the discretion of the investigator and after 
consultation with the sponsor unless screen failure is due to a positive urine drug screen 
for illicit substances other than tetrahydrocannabinol (THC) (Section 5.2, exclusion 18). 
Subjects who have a positive urine drug screen for THC at screening may be rescreened 
once and randomized into the trial if the repeat urine drug screen is negative for THC, 
and the subject agrees to abstain from THC use throughout the duration of the trial. 
Rescreened subjects will be assigned a new subject number.

office or facility to another within the sites network) for all IMP received and any 
discrepancies are reported and resolved before use of the IMP. 
Only subjects who are enrolled in the trial may receive IMP and only authorized site staff 
may supply or administer IMP. All IMP must be stored in a secure, environmentally 
controlled, and monitored (manual or automated) area in accordance with the labeled 
storage conditions, with access limited to the investigator and authorized site staff. 
The investigator is responsible for IMP accountability, reconciliation, and record 
maintenance (ie, receipt, reconciliation, and final disposition records). 
Further guidance and information for the final disposition of unused IMPs are provided in 
the appropriate protocol-specific manuals. 
6.3 
Measures to Minimize Bias: Randomization and Blinding 
6.3.1 
Subject Assignment to Treatment 
All subjects will be centrally randomized in a 1:1:1 ratio to 1 of 3 treatment arms 
(tavapadon 5 mg QD, tavapadon 15 mg QD, or placebo) at the Baseline Visit via an 
Interactive Voice Response System/Interactive Web Response System (IVRS/IWRS), 
according to a computer-generated randomization scheme. Randomization will be 
stratified by concurrent use of allowed antiparkinsonian medication (MAO-B inhibitor) 
 


Protocol CVL-751-PD-001
Tavapadon
 
Confidential

Version 4.0: 06 Jul 2023
 
 
during the Treatment Period. Subjects will be sequentially assigned to the next available 
randomization number within the appropriate randomization stratum and will receive the 
IMP that corresponds to that randomization number. Once a randomization number has 
been assigned, it will not be reassigned. 
The telephone number and call-in directions for the IVRS and/or the log-in information 
for and directions for the IWRS will be provided to each trial site before the trial is 
initiated. 
6.3.2 
Blinding 
The tavapadon and placebo tablets will be identical in appearance and will be packaged 
in identically appearing blister cards. All subjects will take 3 tablets once daily of IMP 
throughout the Treatment Period, either all tavapadon tablets, all placebo tablets, or a 
combination of tavapadon and placebo tablets. Tablets will be packaged to allow dosage 
adjustments (as shown in Table 4) to be made without breaking the trial blind. 
Treatment assignments will be blinded to the investigators and other trial site personnel, 
the subjects, and all sponsor personnel who are involved in the conduct of the trial 
(including trial monitoring, data management, and data analysis). Access to the treatment 
codes will be restricted to personnel who are responsible for generating and maintaining 
the randomization code, packaging the IMPs, operating the IVRS/IWRS, analyzing the 
PK blood samples, or reporting serious adverse events (SAEs) or adverse events of 
special interest (AESI) to regulatory agencies. 
At the initiation of the trial, investigators and site personnel will be instructed on the 
method for breaking the blind. The IVRS/IWRS will be programmed with blind-breaking 
instructions. In case of an emergency, the investigator has the sole responsibility for 
determining if unblinding of the treatment assignment for an individual subject is 
warranted. Subject safety must always be the first consideration in making such a 
determination. If the investigator decides that unblinding is warranted, the investigator 
should make every effort to contact the sponsor before unblinding a subject’s treatment 
assignment unless this could delay emergency treatment of the subject. The sponsor must 
be notified within 24 hours after breaking the blind for a trial subject. 
Documentation of breaking the blind should be recorded in the subject’s medical record 
and electronic case report forms (eCRFs), with the reason for breaking the blind, the date 
and time the blind was broken, and the names of the personnel involved. Once the blind 
is broken for a subject, treatment with the IMP may not be reinitiated for that subject.  
6.4 
Trial Treatment Compliance 
All IMP will be dispensed by responsible trial personnel. Subjects will be counseled on 
the importance of taking the IMP as directed (once daily in the morning, with or without 
food) at each clinic visit and will be instructed to bring all used and unused blister cards 
to each clinic visit. Accountability and compliance (as assessed through self-reporting by 
the subject and by tablet count at each clinic visit) will be documented in the subject’s 
 


Protocol CVL-751-PD-001
Tavapadon
 
Confidential 
Page 33 of 92 
Version 4.0: 06 Jul 2023
 
 
trial records. Deviation(s) from the prescribed dosage regimen should be recorded in the 
eCRF. 
If poor compliance is encountered (eg, multiple missed doses resulting in <80% overall 
compliance at any point in the trial), discontinuation of the subject from the trial should 
be considered. Subjects who habitually miss visits or habitually attend visits outside of 
the protocol-defined visit window are also defined as noncompliant and should be 
considered for discontinuation. The medical monitor should be contacted if the 
investigator is uncertain whether a subject’s lack of compliance merits discontinuation 
from the trial. 
6.5 
Concomitant Therapy 
6.5.1 
Prior and Concomitant Medications 
The investigator will record all medications and therapies (including vaccines, 
over-the-counter or prescription medicines, vitamins, and/or herbal supplements) that are 
used by the subject from 30 days before the informed consent form (ICF) is signed 
through the end of the 4-week Safety Follow-up Period (Week 31 or early termination). 
The investigator will also record all medications and therapies taken or received by a 
subject for treatment of an AE or that cause an AE through Week 31 or early termination.  
The medication, indication, dose, frequency, route, and start and end dates will be 
recorded in the eCRFs for each concomitant medication, and the therapy, indication, and 
start and end dates will be recorded in the eCRFs for any concomitant therapy. The 
medical monitor should be contacted if there are any questions regarding concomitant or 
prior therapy. 
All subjects should be counselled on the importance of taking background medications as 
prescribed.  
6.5.2 
Prohibited Medications Before the Trial 
Subjects must agree to discontinue use of all prohibited medications in accordance with 
predefined washout periods, as shown in Table 6.

Dose Modification 
This is a fixed-dose trial of tavapadon 5 mg QD and tavapadon 15 mg QD. The dose of 
tavapadon will be titrated to the randomized dose, as shown in Table 4, and then 
maintained for the remainder of the trial. Procedures for dose modification are provided 
in Section 4.1.2.  
Dose modifications will be achieved by issuing new IMP blister cards with the adjusted 
dose to the subject such that the subject continues to take 3 tablets once daily. The IMP 
will be packaged in a manner that will allow dose modifications to be made without 
unblinding the trial. 
6.6 
Intervention after the End of the Trial 
Subjects who complete through Week 27 of the trial may have the opportunity to receive 
open-label treatment with tavapadon in an open-label extension trial 
(Protocol CVL-751-PD-004). Subjects who are ineligible or elect not to enter the 
open-label extension trial will resume treatment with available antiparkinsonian 
medications at the discretion of and as determined by their physician.

7 DISCONTINUATION OF TRIAL INTERVENTION AND 
SUBJECT DISCONTINUATION/WITHDRAWAL 
7.1 
Discontinuation of Entire Trial 
If the sponsor terminates or suspends the trial for any reason, prompt notification will be 
given to investigators, Institutional Review Boards/Independent Ethics Committees 
(IRBs/IECs), and regulatory authorities in accordance with regulatory requirements. 
7.2 
Discontinuation of Individual Site 
Participation of an individual trial site may be discontinued by the sponsor, the 
investigator, or the IRB/IEC if judged to be necessary for medical, safety, regulatory, 
ethical, or other reasons consistent with applicable laws, regulations, and Good Clinical 
Practice (GCP). The investigator will notify the sponsor promptly if the trial is terminated 
by the investigator or the IRB/IEC at the site. 
7.3 
Individual Subject Discontinuation 
After treatment assignment, a subject may stop treatment permanently for a variety of 
reasons. Treatment discontinuation may be initiated by a subject who is not satisfied with 
treatment or may become medically necessary due to AEs, required treatment with a 
disallowed medication or therapy, or other issues, as determined by the investigator.  
A subject may discontinue the IMP for any of the following reasons: 
• 
Adverse event  
• 
Death 
• 
Worsening of PD symptoms to such an extent that, in the judgment of the 
investigator, the subject requires additional anti-PD medications 
• 
Treatment with prohibited concomitant medications 
• 
Noncompliance with the study schedule 
• 
Noncompliance with the study drug 
• 
Withdrawal by subject 
• 
Pregnancy 
• 
Physician decision 
If a subject discontinues the IMP due to an AE, the investigator or other trial personnel 
will make every effort to follow the event until it has resolved or stabilized.  
All subjects have the right to withdraw consent for further participation in the trial at any 
time without prejudice. Subjects cannot withdraw consent for use of data that have 
already been collected as part of the trial but can withdraw consent for future 
 


Protocol CVL-751-PD-001
Tavapadon
 
Confidential 
Page 38 of 92 
Version 4.0: 06 Jul 2023
 
 
participation. The investigator can also discontinue a subject from the trial at any time if 
medically necessary. Unless the subject provides written withdrawal of consent or there 
is other written documentation by the investigator confirming the subject’s verbal intent 
to completely withdraw from the trial, subjects should be followed for all 
protocol-specified evaluations and assessments, if possible. 
Complete withdrawal of consent requires a subject to refuse of ALL of the following 
methods of follow-up: 
• 
Participation in all follow-up procedures specified in the protocol (whether in-clinic 
or by telephone) 
• 
Participation in a subset of protocol specified follow-up procedures (by a frequency 
schedule and method, as agreed by subject and staff) 
• 
Contact of the subject by trial personnel, even if only by telephone, to assess current 
medical condition, and obtain necessary medical or laboratory reports relevant to the 
trial’s objectives 
• 
Contact of an alternative person(s) who has been designated in source records as 
being available to discuss the subject’s medical condition, even if only by telephone, 
mail, or e-mail (eg, family, spouse, partner, legal representative [as defined per local 
regulations], friend, neighbor, or physician) 
• 
Access to medical information from alternative sources (eg, hospital/clinic medical 
records, referring doctor’s notes, public records, dialysis, transplantation or vital 
registries, social media sources). 
Withdrawal of consent is a critical trial event and, therefore, should be approached with 
the same degree of importance and care as is used in initially obtaining informed consent. 
The reasons for a subject’s intended withdrawal need to be completely understood, 
documented, and managed to protect the rights of the subject and the integrity of the trial. 
A subject may initially express the desire to interrupt, modify, or discontinue 
administration of the IMP, which is not equivalent to a complete withdrawal of consent 
for further participation. A subject may, however, indicate that further trial participation 
is creating a burden on his or her work, school, or social schedule. Therefore, the 
investigator should determine if the subject can continue participation in the trial if 
modifications to his/her treatment and/or schedule of assessments can be accommodated. 
Only subjects who withdraw their permission for all of the above methods of follow-up 
are considered to have completely withdrawn their consent to participate in the trial. 
Details on the withdrawal of consent for the optional banked biospecimen sample are 
provided in the separate ICF for that sample. 
7.4 
Lost to Follow up 
A subject will be considered lost to follow-up if he or she repeatedly fails to return for 
scheduled visits and is unable to be contacted by trial site personnel. 
 


Protocol CVL-751-PD-001
Tavapadon
 
Confidential 
Page 39 of 92 
Version 4.0: 06 Jul 2023
 
 
The following actions must be taken if a subject fails to return to the clinic for a required 
trial visit: 
• 
The site must attempt to contact the subject and reschedule the missed visit as soon 
as possible and counsel the subject on the importance of maintaining the assigned 
visit schedule and ascertain whether or not the subject wishes to and/or should 
continue in the trial. 
• 
Before a subject is deemed lost to follow up, the investigator or designee must make 
every effort to regain contact with the subject (where possible, 3 telephone calls and, 
if necessary, a certified letter to the subject’s last known mailing address or local 
equivalent methods). These contact attempts should be documented in the subject’s 
medical record. 
• 
Should the subject continue to be unreachable, he/she will be considered to have 
withdrawn from the trial.  
8 TRIAL ASSESSMENTS AND PROCEDURES 
Trial procedures and their timing are summarized in the Schedule of Assessments 
(Table 2). Protocol waivers or exemptions are not allowed. 
Immediate safety concerns should be discussed with the sponsor immediately upon 
occurrence or awareness to determine if the subject should continue or discontinue trial 
intervention.  
Adherence to the trial design requirements, including those specified in the Schedule of 
Assessments, is essential and required for trial conduct. 
8.1 
Screening and Baseline Assessments 
All screening evaluations must be completed and reviewed to confirm that potential 
subjects meet all eligibility criteria. Data collected as part of the screening process may 
be submitted to sponsor/clinical research organization (CRO) in order to facilitate 
eligibility assessment. Protocol waivers or exemptions are not allowed. The investigator 
will maintain a screening log to record details of all subjects who are screened and to 
confirm eligibility or record reasons for screening failure, as applicable.  
Procedures that are conducted as part of the subject’s routine clinical management (eg, 
blood count) and obtained before the ICF is signed may be used for screening or baseline 
purposes provided the procedures meet the protocol-specified criteria and were 
performed within the time frame that is defined in the Schedule of Assessments 
(Table 2). 
As part of the screening procedures, the investigator will assess the severity of each 
subject’s PD symptoms using the modified Hoehn and Yahr scale (Hoehn and Yahr, 
1967; Goetz et al, 2004) on which: 
 


Protocol CVL-751-PD-001
Tavapadon
 
Confidential 
Page 40 of 92 
Version 4.0: 06 Jul 2023
 
 
Stage Definition 
1 = Unilateral involvement only 
1.5 = Unilateral and axial involvement 
2 = Bilateral involvement without impairment of balance 
2.5 = Mild bilateral disease with recovery on pull test 
3 = Mild to moderate bilateral disease; some postural instability; physically 
independent 
4 = Severe disability; still able to walk or stand unassisted 
5 = Wheelchair bound or bedridden unless added 
Subjects must have a modified Hoehn and Yahr stage of 1, 1.5, or 2 for inclusion in the 
trial. 
The investigator will also administer the Montreal Cognitive Assessment (MoCA) to 
detect the subject’s level of cognitive impairment (Nasreddine et al, 2005). The MoCA is 
administered over approximately 10 minutes to gauge areas of language, visuospatial 
ability, memory, recall, and abstract thinking. The total possible score is 30, with any 
score greater than 25 considered normal. Scores of 25 or less are considered to be an 
indication of some form of cognitive impairment. Subjects with a MoCA score <26 will 
not be eligible for the trial. 
8.2 
Efficacy Assessments 
The planned time points for efficacy assessments are shown in the Schedule of 
Assessments (Table 2). At each clinic visit, efficacy assessments should be completed 
first, followed by the safety assessments. 
8.2.1 
Movement Disorder Society-Unified Parkinson’s Disease Rating 
Scale 
The MDS-UPDRS (Goetz et al, 2008) is a multidimensional scale that assesses the motor 
and nonmotor impacts of PD across 4 parts. The scale is completed using a combination 
of physician and patient assessments and a collection of information from the patient or 
caregiver: 
• 
Part I, nonmotor aspects of experiences of daily living, comprises 13 items, 6 of 
which are rated by the physician (Part IA) and 7 of which are rated by the patient 
(Part IB).  
• 
Part II, motor aspects of experiences of daily living, comprises 13 items that are 
rated by the patient. The 13 items in Part II and the 7 items in Part IB constitute the 
patient questionnaire portion of the MDS-UPDRS. 
• 
Part III, motor examination, comprises 18 items that are assessed by the investigator 
(resulting in 33 scores by location and lateralization). 
 


Protocol CVL-751-PD-001
Tavapadon
 
Confidential 
Page 41 of 92 
Version 4.0: 06 Jul 2023
 
 
• 
Part IV, motor complications, comprises 6 item (3 items for dyskinesia and 3 items 
for fluctuation) and requires the physician to use historical and objective information 
to assess dyskinesia and motor fluctuations. 
Each item is rated on a scale from 0 to 4 on which 0 = normal, 1 = slight, 2 = mild, 
3 = moderate, and 4 = severe. 
The same individual should perform the ratings for an individual subject throughout the 
course of the trial. The postbaseline MDS-UPDRS assessments will be conducted in the 
clinic, ~2 to ~6 hours after the subjects have taken their daily dose of IMP (at home), at 
the end of Weeks 5, 8, 11, 14, 18, 22, 26, and 27.  
8.2.2 
Clinical Global Impression – Severity of Illness 
The Clinical Global Impression – Severity of Illness (CGI-S) scale is a 7-point scale that 
requires the clinician to rate the severity of the patient’s illness at the time of the 
assessment relative to the clinician’s past experience with patients who have the same 
diagnosis (Guy, 1976). Raters select one response based on the following question: 
“Considering your total clinical experience with this particular population, how ill is the 
patient at this time?” Scores are: 1=normal, not at all ill; 2=borderline ill; 3=mildly ill; 
4=moderately ill; 5=markedly ill; 6=severely ill; and 7=among the most extremely ill 
patients. 
8.2.3 
Clinical Global Impression – Improvement 
The Clinical Global Impression – Improvement (CGI-I) a 7-point scale that requires the 
clinician to assess how much the patient's illness has improved or worsened relative to 
the baseline state at the beginning of the intervention (Guy, 1976). Raters select one 
response based on the following question, “Compared to your patient’s condition at the 
beginning of treatment, how much has your patient changed?” Scores are: 1=very much 
improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 
6=much worse; and 7=very much worse. 
8.2.4 
Patient Global Impression of Change 
The PGIC is the patient-reported outcome counterpoint to the CGI-I. The qualitative 
assessment of meaningful change is determined by the patient in response to the question, 
“Compared to your condition at the beginning of treatment, how much has your condition 
changed?” Scores are: 1=very much improved; 2=much improved; 3=minimally 
improved; 4=no change; 5=minimally worse; 6=much worse; and 7=very much worse. 
8.2.5 
39-Item Parkinson’s Disease Questionnaire 
The 39-item Parkinson’s Disease Questionnaire (PDQ-39) is the most thoroughly 
validated and extensively used self-report measure for the assessment of health-related 
quality of life in people with PD. The questionnaire measures 39 items, which assess 
8 domains of health: mobility (10 items), activities of daily living (6 items), emotional 
 


Protocol CVL-751-PD-001

Version 4.0: 06 Jul 2023
 
 
well-being (6 items), stigma (4 items), social support (3 items), cognitions (4 items), 
communication (3 items), and bodily discomfort (3 items) (Peto et al, 1998). Each item is 
scored on the following scale: 0=never, 1=occasionally, 2=sometimes, 3=often, and 
4=always. Items in each subscale and the total scale can be summarized into an index and 
transformed linearly to a scale from 0 (perfect health as assessed by the measure) to 100 
(worst health as assessed by the measure).  
8.2.6 
Schwab and England Activities of Daily Living Scale 
The Schwab and England Activities of Daily Living (ADL) scale is a method of assessing 
a person’s ability to perform daily activities in terms of speed and independence through 
a percentage figure (Schwab and England, 1969). The clinician determines the rating 
according to the following criteria, with 100% indicating total independence and 0% 
indicating a state of complete dependence: 
100% Completely independent. Able to do all chores without slowness, 
difficulty or impairment. Essentially normal. Unaware of any difficulty. 
90% 
Completely independent. Able to do all chores with some degree of 
slowness, difficulty and impairment. May take twice as long. Beginning 
to be aware of difficulty 
80% 
Completely independent in most chores. Takes twice as long. Conscious 
of difficulty and slowness. 
70% 
Not completely independent. More difficulty with some chores. Three to 
four times as long in some. May spend a large part of the day with chores. 
60% 
Some dependency. Can do most chores, but exceedingly slowly and with 
much effort. Errors; some impossible. 
50% 
More dependent. Help with half, slower, etc. Difficulty with everything. 
40% 
Very dependent. Can assist with all chores, but few alone 
30% 
With effort, now and then does a few chores alone or begins alone. Much 
help needed 
20% 
Nothing alone. Can be a slight help with some chores. Severe invalid 
10% 
Totally dependent, helpless. Complete invalid. 
0% 
Vegetative functions such as swallowing, bladder and bowel functions are 
not functioning. Bedridden. 
8.2.7 
EuroQol 5 Dimension 5 Level 
The EuroQol 5 Dimension 5 Level (EQ-5D-5L) is a patient-reported outcome that 
measures health in 5 dimensions. It is a widely used survey instrument for measuring 
economic preferences for health states, is applicable to a wide variety of health conditions 
and treatments, and provides a simple descriptive profile and a single index value for 
 


Protocol CVL-751-PD-001
Tavapadon
 
Confidential 
Page 43 of 92 
Version 4.0: 06 Jul 2023
 
 
health status (Herdman et al, 2011). The EQ-5D-5L consists of a descriptive system and a 
visual analog scale (VAS). 
The descriptive system comprises 5 dimensions: mobility, self-care, usual activities, 
pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, 
slight problems, moderate problems, severe problems, and extreme problems. The patient 
is asked to indicate his or her health state by ticking the box next to the most appropriate 
statement in each of the 5 dimensions. This decision results in a 1-digit number that 
expresses the level that was selected for that dimension. The digits for the 5 dimensions 
are combined into a 5-digit number that describes the patient’s health state. 
The EQ-5D-5L VAS records the patient’s self-rated health on a vertical VAS on which 
the endpoints are labeled “the best health quality that you can imagine” and “ the worst 
health quality that you can imagine.” The VAS can be used as a quantitative measure of 
health outcome that reflects the patient’s own judgment. 
8.3 
Safety Assessments 
Planned time points for all safety assessments are provided in the Schedule of 
Assessments (Table 2).  
Safety assessments should be performed after all efficacy assessments have been 
completed. Assessments should be performed in the following order: 
• Epworth Sleepiness Scale (ESS) 
• Questionnaire for Impulsive-Compulsive Disorders in Parkinson’s Disease Rating 
Scale (QUIP-RS) 
• Columbia-Suicide Severity Rating Scale (C-SSRS) 
• Physical and neurological examinations 
• Vital signs  
• Electrocardiograms 
• Blood specimen collection 
• Other procedures (eg, concomitant medications, AEs): all other procedures may be 
obtained before or after blood specimen collection 
8.3.1 
Epworth Sleepiness Scale 
The ESS is a scale that is intended to measure daytime sleepiness (Johns, 1991). It 
assesses the likelihood of dozing off or falling asleep in the following common situations: 
sitting and reading, sitting inactive in a public place (eg, in a meeting, theater, dinner

event), as a passenger in a car for an hour or more without stopping for a break, lying 
down to rest when circumstances permit, sitting and talking to someone, sitting quietly 
after a meal without alcohol, and in a car while stopped for a few minutes in traffic or at a 
light. Each situation is rated as 0=would never nod off, 1=slight chance of nodding off, 
2=moderate chance of nodding off, or 3=high chance of nodding off. A score ≥10 
indicates that the patient may need to get more sleep, improve sleep practices, or seek 
medical attention to determine why he or she is sleepy. 
8.3.2 
Questionnaire for Impulsive-Compulsive Disorders in Parkinson’s 
Disease-Rating Scale 
The QUIP-RS is a global screening instrument that assesses ICDs and related disorders 
(punding, hobbyism, and dopamine dysregulation syndrome) in patients with PD 
(Weintraub et al, 2012). The QUIP-RS has 4 primary questions that pertain to commonly 
reported thoughts, urges/desires, and behaviors associated with ICDs, each of which is 
applied to 4 ICDs (compulsive gambling, buying, eating, sexual behavior) and 3 related 
disorders (medication use, punding, and hobbyism).  
The QUIP-RS uses a 5-point Likert scale (score 0–4 for each question) to gauge the 
frequency of behaviors. Patients are instructed to answer questions based on behaviors 
that occurred in the preceding 4 weeks or during any 4-week period in a designated time 
frame and are provided with a brief description of the behaviors that are being assessed 
and with a brief description of the Likert scale categories for frequency (eg, 0=never [not 
at all], 1=rarely [infrequently or 1 day/week]). Scores for each ICD and related disorder 
range from 0 to 16, with a higher score indicating greater severity (frequency) of 
symptoms. The total QUIP-RS score for all ICDs and related disorders combined ranges 
from 0 to 112. 
8.3.3 
Columbia-Suicide Severity Rating Scale 
Suicidality will be monitored during the trial using the C-SSRS. This semi-structured 
interview was originally developed to evaluate the link between antidepressants and 
suicidal behavior and ideation in youth and AEs from pediatric clinical trials (Posner et 
al, 2011). It was designed to quantify the severity of suicidal ideation and behavior. Trial 
personnel who administer the C-SSRS must complete the appropriate training and have 
valid certification. Training on the scale will be provided via the sponsor. 
This trial will use the “Baseline/Screening” and “Since Last Visit” versions of the scale. 
The “Baseline/Screening” version, which assesses the lifetime experience of the subject 
with suicide events and suicidal ideation and the occurrence of suicide events or ideation 
within a specified time period prior to entry into the trial, will be completed for all 
subjects at screening to determine eligibility and confirmed at baseline. Any subject with 
active suicidal ideation or suicidal behaviors within the last 6 months, suicidal behaviors 
within the last 2 years, or who in the clinical judgment of the investigator presents a 
serious risk of suicide should be excluded from the trial (Section 5.2). 
 


Protocol CVL-751-PD-001

Confidential 
Page 45 of 92 
Version 4.0: 06 Jul 2023
 
 
The “Since Last Visit” C-SSRS form will be completed at all visits after screening and 
baseline. The investigator will review the results of the “Since Last Visit” C-SSRS during 
the trial to determine whether it is safe for the subject to continue in the trial. If a subject 
demonstrates potential suicidal ideation associated with actual intent or method or plan as 
indicated by “YES” answers on item 4 or 5 of the C-SSRS, the investigator will evaluate 
whether a risk assessment by a qualified mental health professional (or the investigator 
alone if the investigator is a qualified mental health professional) is needed and whether 
the subject should continue in or be discontinued from the trial. 
8.3.4 
Physical and Neurological Examinations 
A complete physical examination will consist of measurement of height (screening only) 
and weight and a review of the following body systems: head, ears, eyes, nose, mouth, 
skin, heart and lungs, lymph nodes, and gastrointestinal and musculoskeletal systems. 
A full neurological examination will include an assessment of the subject’s mental status 
(level of consciousness, orientation, speech, memory, etc), cranial nerves, motor (muscle 
appearance, tone, strength and reflexes), sensation (including Romberg sign), 
coordination, and gait. 
Height will be measured with a stadiometer, measuring stick, or tape.  
The following guidelines will aid in the standardization of body weight measurements: 
• 
The same scale should be used to weigh a given subject each time, if possible. 
• 
Scales should be calibrated and reliable; scales should be at zero just prior to each 
subject’s weigh-in session. 
• 
A subject should void prior to being weighed and be minimally clothed (ie, no shoes 
or heavy overgarments). 
• 
Weight should be recorded before a subject’s meal and at approximately the same 
time at each visit. 
The investigator (or designee) is responsible for performing the physical and neurological 
examinations. If the appointed designee is to perform these examinations, he or she must 
be permitted by local regulations and his or her name must be included on the delegation 
of authority log. Whenever possible, the same individual should perform all physical and 
neurological examinations.  
Any condition present at the posttreatment physical or neurological examination that was 
not present at the baseline examination should be documented as an AE and followed to a 
satisfactory conclusion. 
8.3.5 
Vital Signs 
Vital signs include systolic and diastolic blood pressures, heart rate, and body 
temperature. Duplicate measurements of blood pressure and heart rate will be obtained in 
 


Protocol CVL-751-PD-001
Tavapadon
 
Confidential 
Page 46 of 92 
Version 4.0: 06 Jul 2023
 
 
supine (after 5 minutes of rest) and 1 measurement of blood pressure and heart rate will 
be obtained on standing (2 minutes after rising from supine to standing). The duplicate 
values will be individually recorded, and the values will be averaged by the sponsor for 
the time point assessment. Body temperature will be obtained once, at the time of the first 
blood pressure measurement. 
Additional information related to measurement of blood pressure and heart rate is 
provided in the appropriate protocol-specific manuals. 
8.3.6 
Electrocardiograms 
Single or triplicate 12-lead ECGs will be obtained during the trial. All ECG recordings 
will be obtained after the subject has been supine and at rest for at least 5 minutes. A 
triplicate set of ECGs is 3 consecutive ECGs collected 1 to 2 minutes apart over a 
5-minute period. 
For US sites, a single ECG will be obtained at the Screening Visit unless additional ECGs 
are required as described below. Three sets of triplicate ECGs will be obtained during the 
45 minutes before administration of the first dose of IMP on Day 1 (at -45, -30, 
and -15 minutes), and a single set of triplicate ECGs will be obtained ~1 hour after 
administration of the first dose of IMP on Day 1, just prior to the time of collection of the 
PK blood sample. One set of triplicate ECGs will be obtained at the Weeks 5, 11, 14, 22, 
and 27 clinic visits, just prior to the time of collection of the PK blood sample. The 
triplicate ECG information from US sites will be used in a C-QT analysis, as described in 
Section 10.7 (Appendix 7). 
For non-US sites, a single ECG will be obtained at the Screening Visit unless additional 
ECGs are required as described below. One set of triplicate ECGs will be obtained before 
administration of the first dose of IMP on Day 1, and a single ECG will be obtained 
~1 hour after administration of the first dose of IMP on Day 1, just prior to the time of 
collection of the PK blood sample. Single ECGs will be obtained at the Weeks 5, 11, 14, 
22, and 27 clinic visits, just prior to the time of collection of the PK blood sample. 
Additional 12-lead ECGs may be obtained at the investigator’s discretion and should 
always be obtained in the event of an early termination.  
The ECG results will be evaluated at the investigational site to determine the subject’s 
eligibility and to monitor safety during the trial. The principal investigator (or qualified 
designee) will review, sign, and date each ECG reading, noting whether or not any 
abnormal results are of clinical significance. The ECG will be repeated if any results are 
considered to be clinically significant. A central ECG service will be used for reading all 
ECGs to standardize interpretations for the safety analysis. 
If, during screening, any abnormal ECG finding is deemed medically significant 
(impacting the safety of the subject or the interpretation of the trial results) or meets an 
exclusion criterion (see Section 5.2), the subject should be excluded from the trial. 
Medically significant or exclusory abnormal results on an ECG at screening should be 
 


Protocol CVL-751-PD-001

Confidential 
Page 47 of 92 
Version 4.0: 06 Jul 2023
 
 
repeated with 2 additional ECG recordings to ensure reproducibility of the abnormality, 
and the 3 ECG recordings read by the central service to confirm the abnormality before 
excluding a subject. For subjects with a QTcF >450 msec at screening, a subject will be 
excluded if the QTcF intervals reported by the central service are >450 msec for 2 or 
more of the 3 ECG recordings, unless due to ventricular pacing. If, at the Baseline Visit, 
the QTcF interval is >450 msec on the machine readings, consult the medical monitor to 
determine whether the subject remains eligible to be randomized while awaiting the 
readings from the central service. 
Exclusion criteria for screening do not apply as mandatory discontinuation criteria for 
subjects who are already randomized. A repeat ECG should be performed to confirm any 
clinically significant abnormality that is identified in a randomized subject during the 
treatment period (which will be confirmed by central service read) and, in these cases, the 
medical monitor should be consulted on the appropriateness of the subject continuing in 
the trial. 
8.3.7 
Clinical Safety Laboratory Assessments 
The list of clinical laboratory tests that are to be performed is provided in Section 10.2 
(Appendix 2). All protocol-required laboratory assessments must be conducted in 
accordance with the laboratory manual and the Schedule of Assessments (Table 2). 
The investigator must review the laboratory report, document this review, and record any 
clinically relevant changes occurring during the trial in the AE section of the eCRF. The 
laboratory reports must be filed with the source documents. Clinically significant 
abnormal laboratory findings are those that are not associated with the underlying 
disease, unless judged by the investigator to be more severe than expected for the 
subject's condition. 
All laboratory tests with values that are considered clinically significantly abnormal 
during participation in the trial should be repeated until the values return to normal, to 
baseline, or are no longer considered clinically significant by the investigator or medical 
monitor. If such values do not return to normal/baseline within a period of time judged 
reasonable by the investigator, the etiology should be identified and the sponsor notified. 
All protocol-required laboratory assessments, as defined in Section 10.2 (Appendix 2), 
must be conducted in accordance with the laboratory manual and the Schedule of 
Assessments (Table 2).

Adverse Events, Serious Adverse Events, and Adverse Events of 
Special Interest 
The definitions of an AE and SAE are provided in Section 10.3 (Appendix 3). The AESI 
for this trial are defined in Section 8.4.6. 
Adverse events will be reported by the subject (or, when appropriate, by a caregiver, 
surrogate, or the subject's legally authorized representative, as defined per local 
regulations).The investigator and any qualified designees are responsible for detecting, 
documenting, and recording events that meet the definition of an AE, SAE, or AESI and 
remain responsible for following up SAEs/AESI that are considered related to the trial 
intervention or trial procedures or that cause the subject to discontinue IMP (see 
Section 7.3). 
8.4.1 
Time Period and Frequency for Collecting AE and SAE/AESI 
Information 
All AEs and SAEs/AESIs will be recorded from the first dose of IMP until follow-up 
contact at the time points specified in the Schedule of Assessments (Table 2). 
 


Protocol CVL-751-PD-001
Tavapadon

Page 49 of 92 
Version 4.0: 06 Jul 2023
 
 
Medical occurrences that begin before the start of IMP dosing but after obtaining 
informed consent will be recorded as medical and/or psychiatric history. 
All SAEs/AESI will be recorded and reported to the sponsor or designee immediately and 
under no circumstance should this exceed 24 hours, as indicated in Section 10.3 
(Appendix 3). The investigator will submit any updated SAE/AESI data to the sponsor 
within 24 hours of it being available. 
Investigators are not obligated to actively seek AEs, SAEs, or AESI after conclusion of 
the trial participation. However, if the investigator learns of any SAE, including a death, 
at any time after a subject has been discharged from the trial, or AESI and he/she 
considers the event to be reasonably related to the trial intervention or trial participation, 
the investigator must promptly notify the sponsor. 
8.4.2 
Method of Detecting AEs and SAEs/AESI 
The method of recording, evaluating, and assessing causality of AEs and SAEs/AESI and 
the procedures for completing and transmitting SAE/AESI reports are provided in 
Section 10.3 (Appendix 3). 
Care will be taken not to introduce bias when detecting AEs and/or SAEs/AESI. 
Open-ended and nonleading verbal questioning of the subject is the preferred method to 
inquire about AE occurrences. 
8.4.3 
Follow-up of AEs and SAEs/AESI 
After the initial AE/SAE/AESI report, the investigator is required to proactively follow 
each subject at subsequent visits/contacts. All SAEs/AESI will be followed until 
resolution, stabilization, the event is otherwise explained, or the subject is lost to 
follow-up (as defined in Section 7.4). Further information on follow-up procedures is 
given in Section 10.3 (Appendix 3). 
8.4.4 
Regulatory Reporting Requirements for SAEs/AESI 
Prompt notification by the investigator to the sponsor of an SAE/AESI is essential so that 
legal obligations and ethical responsibilities towards the safety of subjects and the safety 
of a trial intervention under clinical investigation are met. 
The sponsor has a legal responsibility to notify both the local regulatory authority and 
other regulatory agencies about the safety of a trial intervention under clinical 
investigation. The sponsor will comply with country-specific regulatory requirements 
relating to safety reporting to the regulatory authority, IRBs/IECs, and investigators. 
Investigator safety reports must be prepared for suspected unexpected serious adverse 
reactions (SUSAR) according to local regulatory requirements and sponsor policy and 
forwarded to investigators as necessary.

Version 4.0: 06 Jul 2023
 
 
An investigator who receives an investigator safety report describing an SAE/AESI or 
other specific safety information (eg, summary or listing of SAEs/AESI) from the 
sponsor will review and then file it along with the Investigator’s Brochure and will notify 
the IRB/IEC, if appropriate, according to local requirements. 
8.4.5 
Pregnancy 
Details of all pregnancies in female subjects or in female partners of male subjects will be 
collected after the start of trial intervention and until 4 weeks after the last dose.  
If a pregnancy is reported, the investigator should inform the sponsor within 24 hours of 
learning of the pregnancy and should follow the procedures outlined in Section 10.4 
(Appendix 4). 
Abnormal pregnancy outcomes (eg, spontaneous abortion, fetal death, stillbirth, 
congenital anomalies, ectopic pregnancy) are considered SAEs. 
8.4.6 
Adverse Events of Special Interest 
8.4.6.1 
Adverse Events Potentially Related to Abuse 
A key objective of the Abuse Potential Monitoring Plan (APMP) is to monitor for 
instances of abuse or diversion of the trial medication and other psychoactive substances. 
In addition to monitoring for irregularities in medication handling, AEs that may be 
suggestive of a developing abuse issue will also receive special attention. As part of the 
APMP, medication handling irregularities (MHIs) must be reported, and AEs related to 
abuse potential and AEs involving MHIs must be reported as events subject to additional 
monitoring (ESAM), with detailed narratives. 
Investigators and site staff at each trial site will be trained on reporting potentially 
abuse-related AEs (eg, recording a description of the event in the subject’s own words in 
the source documents as well as the eCRF, in addition to the clinical term, and to be 
aware that a subject’s report may encompass more than one event and that these should 
be recorded separately). The investigators will be provided with examples of potentially 
abuse-related AEs and trained on how to handle such events (eg, additional monitoring). 
While the investigators will be provided with examples of AE terms as a guide during 
trial conduct, the analysis of potentially abuse-related AEs will be based on a search by 
the sponsor of all relevant Medical Dictionary for Regulatory Activities (MedDRA) 
terms, all verbatim terms, and any open text fields within the AE data to identify text 
strings suggestive of abuse potential, consistent with US Food and Drug Administration 
(FDA) guidance (Guidance for Industry: Assessment of Abuse Potential of Drugs, 
January 2017).

Complete details, including documenting and reporting procedures, examples of 
potentially abuse-related terms and guidance for the training of investigators and trial site 
staff are provided in the APMP. 
8.4.6.2 
Abnormal Liver Function Tests 
The finding of an elevated value for alanine aminotransferase (ALT) or aspartate 
aminotransferase (AST) of >3 × the upper limit of normal (ULN) in combination with 
either an elevated value for total bilirubin >2 × ULN or clinical jaundice in the absence of 
cholestasis or other causes of hyperbilirubinemia is considered to be an indicator of 
severe liver injury. Investigators must report the occurrence of either of the following as 
AESI to the sponsor with 24 hours: 
• 
Treatment-emergent value of >3 × ULN for ALT or AST and >2 × ULN for total 
bilirubin 
• 
Treatment-emergent value of >3 × ULN for ALT or AST and clinical jaundice 
Brief narratives will be written for any subjects who experience abnormalities in liver 
function tests that meet the criteria specified above. 
8.4.6.3 
Adverse Events Leading to Discontinuation 
Any AE that leads to discontinuation of IMP or from the trial will be classified as an 
AESI. Brief narratives will be written for subjects who discontinue IMP or from the trial 
because of AEs. 
8.5 
Treatment of Overdose 
Titrated doses of up to 25 mg QD of tavapadon have been evaluated subjects with PD 
(Trial B7601005). Across all doses (5, 15, and 25 mg QD), nausea, vomiting, headache, 
dizziness, and abnormal dreams were the most commonly reported TEAEs. A 
dose-related increase was observed between the 15 mg QD (n=11) and 25 mg QD (n=19) 
doses in the percentage of subjects who experienced gastrointestinal-related TEAEs (27% 
vs 58%), in particular, nausea (27% vs 42%) and vomiting (9.1% vs 21.1%), and in the 
percentage of subjects who discontinued from the trial due to gastrointestinal TEAEs (0% 
vs 16%). Other TEAEs were reported in comparable percentages of subjects. Based on 
these findings, as well as on PK findings, which showed a less-than-dose-proportional 
increase in exposure between the 15 and 25 mg doses (consistent with the 
moderate-to-low solubility of tavapadon at the pH of the gastrointestinal tract of 6.5), 
15 mg QD was identified as the maximum dose in this trial (see also Section 4.3). 
Any dose >15 mg of tavapadon (maximum dose in this trial) within the same calendar 
day will be considered an overdose. There is no specific antidote for overdose with 
tavapadon. In the event of an overdose, the investigator should:

1. 
Contact the medical monitor immediately 
2. 
Closely monitor the subject for any AE/SAE/AESI and laboratory abnormalities 
3. 
Document the quantity of the excess dose, as well as the duration of the 
overdose, in the eCRF 
Decisions regarding dose interruptions or modifications will be made by the investigator 
in consultation with the medical monitor based on the clinical evaluation of the subject. 
8.6 
Pharmacokinetics 
Blood samples for measurement of plasma concentrations of tavapadon and its major 
metabolite (if required) will be collected ~1 hour after administration of the first dose of 
IMP on Day 1 and at the clinic visits at the end of Weeks 5, 11, 14, 22, and 27 just after 
ECG acquisition at each time point, as shown in the Schedule of Activities (Table 2). The 
date and time of the most recent dose, the dose amount, and the time of the blood draw 
will be recorded. Instructions for the collection and handling of biological samples will 
be provided by the sponsor.  
Plasma samples will be processed, stored, and shipped to the bioanalytical facility 
according to the instructions that will be provided to the investigator in advance of the 
trial. A fully validated bioanalytical method will be used to quantitate plasma 
concentrations of tavapadon and its major metabolite (if required).  
Drug concentration information will not be reported to investigative sites or blinded 
personnel until the trial has been unblinded. 
8.7 
Pharmacodynamics 
Triplicate ECGs will be obtained at US sites according to the Schedule of Assessments 
(Table 2) and as described in Section 8.3.6. The data will be used in a C-QT analysis to 
evaluate the effect of tavapadon the QT interval. Additional information related to this 
analysis is provided in Section 10.7 (Appendix 7). 
8.8 
Future Biospecimen Research 
Studying the variation in genetic markers and other biomarkers may help to explain some 
of the variability in response seen with some drugs among different individuals. This is 
referred to as pharmacogenomic/biomarker research. Comparing the DNA, RNA, protein, 
and metabolite variation patterns of subjects who respond well and those who respond 
poorly to treatment may help to better define the most appropriate group of subjects in 
which to target a given treatment. Collecting biospecimens for exploratory 
pharmacogenomic/biomarker analyses and retaining them at Cerevel makes it possible to 
better understand the drug’s mechanism of action and to seek explanations for differences 
in, for example, exposure, efficacy, tolerability, or safety not anticipated prior to the 
beginning of this trial.

Version 4.0: 06 Jul 2023
 
 
Banked biospecimen samples will be collected from subjects who consent to this sample 
collection on a separate ICF. Research performed on these samples may include genetic 
analyses (DNA), gene expression profiling (RNA), proteomics, metabolomics and/or the 
measurement of other analytes. Such research is for biomarker testing to address 
emergent questions not described elsewhere in the protocol (as part of the main trial) and 
will only be conducted on specimens from appropriately consented subjects.  
9 STATISTICAL CONSIDERATIONS 
9.1 
Statistical Hypotheses 
The primary efficacy endpoint is the change from baseline to endpoint in the MDS-
UPDRS Parts II and III combined score. The hypotheses of interest are 2-sided tests of 
superiority comparing each active tavapadon dose to placebo. 
H01: µplacebo = µ15 mg QD vs H11: µplacebo ≠ µ15 mg QD 
H02: µplacebo = µ5 mg QD vs H12: µplacebo ≠ µ5 mg QD 
The hypotheses H01 and H02 will be tested in a sequential order in that if H01 cannot be 
rejected versus H11 at a 2-sided α level of 0.05, the testing sequence will not continue to 
H02 versus H12. 
9.2 
Sample Size Determination 
A total of 522 subjects are planned to be randomized in a 1:1:1 ratio to the 
tavapadon 5mg QD, tavapadon 15 mg QD, or placebo QD treatment group. A sample 
size of 174 subjects per group will provide at least 90% power to detect a change in the 
primary outcome measure (change from baseline to endpoint in the MDS-UPDRS Parts II 
and III combined score) of 4 points, with a standard deviation of 9, 2-sided alpha 
level = 0.05, and assuming a 27% dropout rate.  
In the event of higher than anticipated early terminations due to COVID-19 or other 
reasons, Cerevel may extend enrollment in order to maintain the planned statistical 
power. 
9.3

Statistical Analyses 
Descriptive statistical methods will be used to summarize the data from this trial, with 
statistical testing performed for the efficacy endpoints. Unless stated otherwise, the term 
“descriptive statistics” refers to number of subjects (n), mean, median, standard 
deviation, minimum, and maximum for continuous data, and frequencies and percentages 
for categorical data. Statistical testing will be 2-sided and will be performed using a 
significance (alpha) level of 0.05. All available data for enrolled subjects will be listed by 
subject. Unless otherwise noted, the data will be sorted first by treatment group and 
subject number and then by date within each subject number.  
All statistical analyses will be conducted with the SAS® System, version 9.4 or higher.  
The remainder of this section is a summary of the planned statistical analyses of the 
primary and secondary endpoints as well as a description of planned safety analyses. Full 
details of these analyses will be included in the statistical analysis plan. The statistical 
analysis plan will be developed and finalized before database lock and will provide 
descriptions of the subject populations that will be used in the analysis and procedures for 
addressing missing, unused, and spurious data. 
9.4.1 
Efficacy Analyses 
The efficacy endpoints will be assessed for each of the 2 dose levels of tavapadon versus 
placebo. A hierarchical testing procedure is planned for the primary and key secondary 
endpoints, in the following order, to control the Type I error rate at the 0.05 level 
(2-sided).

Efficacy Analysis 
Endpoint 
Statistical Analysis Methods 
Primary 
 
The primary efficacy endpoint (the change from baseline to endpoint in the 
MDS-UPDRS Parts II and III combined score) will be analyzed using an MMRM. The 
change from baseline at each postbaseline timepoint will be included in the MMRM as 
repeated measures. The baseline score will be included as a covariate, and treatment 
group, visit, the interaction between treatment group and visit, and the stratification 
factor (concurrent use of MAO-B inhibitor; yes/no) will be included as fixed factors. 
An unstructured covariance structure will be utilized. The difference between each 
tavapadon dose level and placebo at endpoint will be estimated based on the LSMeans 
from the MMRM. A hypothetical strategy will be used to address ICEs of potential 
death, treatment discontinuations, missed visits/assessments, and start of prohibited 
concomitant medications. The data after treatment discontinuations or after the start of 
prohibited concomitant medications will be censored under the hypothetical strategy. 
The missing values are assumed to be MAR in the primary analysis, including missing 
due to COVID-19 control measures. Sensitivity analyses will be performed to assess 
the impact of deviation from MAR assumptions on the analysis results. 
Key Secondary 
The key secondary endpoint of the change from baseline to endpoint in the 
MDS-UPDRS Part II score will be analyzed using an MMRM analysis similar to the 
analysis of the primary endpoint. Similar sensitivity analyses will also be performed. 
The key secondary endpoint of percentage of responders at endpoint, defined as a 
score of “much improved” or “very much improved” on the PGIC, will be analyzed 
using the SAS® GLIMMIX procedure for binomial data with logit link. This 
generalized linear mixed model analysis will include response data from each 
postbaseline visit as repeated measures with treatment group, visit, and interaction 
between treatment group and visit as fixed effects. An unstructured covariance 
structure will be used for the repeated measures. If the model fails to converge with 
the unstructured covariance structure, the heterogeneous Toeplitz structure or further 
reduced covariance structure may be used.

Information 
10.4.1 
Definitions: 
10.4.1.1 
Highly Effective Birth Control Methods (Failure Rate <1%) 
A highly effective form of contraception (failure rate of <1%) is defined as follows: 
• 
Combined (estrogen and progestogen containing) hormonal contraception associated 
with inhibition of ovulation: 
• 
Oral 
• 
Intravaginal 
• 
Transdermal 
• 
Progestogen-only hormonal contraception associated with inhibition of ovulation: 
• 
Oral 
• 
Injectable 
• 
Implantable 
• 
Intrauterine device 
• 
Intrauterine hormone-releasing system 
• 
Bilateral tubal occlusion 
• 
Vasectomized partner 
• 
Sexual abstinence is considered a highly effective method only if defined as 
refraining from heterosexual intercourse during the entire period of risk associated 
with the trial treatments. The reliability of sexual abstinence needs to be evaluated in 
relation to the duration of the clinical trial and the preferred and usual lifestyle of the 
subject. 
10.4.1.2 
Acceptable Birth Control Methods (Failure Rate >1% per Year) 
Acceptable birth control methods that result in a failure rate of more than 1% per year 
include: 
• 
Progestogen-only oral hormonal contraception, where inhibition of ovulation is not 
the primary mode of action 
• 
Male or female condom with or without spermicide*  
• 
Cap, diaphragm or sponge with spermicide.* 
*A combination of male condom with a cap, diaphragm, or sponge with spermicide 
(double-barrier methods) is also considered acceptable but is not a highly effective birth control 
method.

10.4.1.3 
Contraception and Pregnancy Avoidance Procedures 
The following definitions apply for contraception and pregnancy avoidance procedures: 
A woman is considered to be a woman of childbearing potential (WOCBP) following 
menarche and until becoming postmenopausal unless permanently sterile. Permanent 
sterilization methods include hysterectomy and bilateral oophorectomy.  
A postmenopausal state is defined as no menses for 12 months without an alternative 
medical cause.  
Sterilized male subjects should be at least 1 year postbilateral vasectomy and must 
confirm that they have obtained documentation of the absence of sperm in the ejaculate 
or have had bilateral orchidectomy. 
10.4.2 
Collection of Pregnancy Information 
10.4.2.1 
Male Subjects With Partners Who Become Pregnant 
• 
The investigator will attempt to collect pregnancy information on any male subject’s 
female partner who becomes pregnant while the male subject is in this trial. This 
applies only to male subjects who receive trial intervention. 
• 
After obtaining the necessary signed informed consent from the pregnant female 
partner directly, the investigator will record pregnancy information on the 
appropriate form and submit it to the sponsor within 24 hours of learning of the 
partner’s pregnancy. The female partner will also be followed to determine the 
outcome of the pregnancy. Information on the status of the mother and child will be 
forwarded to the sponsor. Generally, the follow-up will be no longer than 6 to 
8 weeks following the estimated delivery date. Any termination of the pregnancy 
will be reported regardless of fetal status (presence or absence of anomalies) or 
indication for the procedure.  
10.4.2.2 
Female Subjects Who Become Pregnant 
• 
The investigator will collect pregnancy information on any female subject who 
becomes pregnant while participating in this trial. Information will be recorded on 
the appropriate form and submitted to the sponsor within 24 hours of learning of a 
subject's pregnancy.  
• 
The subject will be followed to determine the outcome of the pregnancy. The 
investigator will collect follow-up information on the subject and the neonate and the 
information will be forwarded to the sponsor. Generally, follow-up will not be 
required for longer than 6 to 8 weeks beyond the estimated delivery date. Any 
termination of pregnancy will be reported, regardless of fetal status (presence or 
absence of anomalies) or indication for the procedure. 
• 
While pregnancy itself is not considered to be an AE or SAE, any pregnancy 
complication or elective termination of a pregnancy will be reported as an AE or

SAE. A spontaneous abortion is always considered to be an SAE and will be 
reported as such. Any post-trial pregnancy related SAE considered reasonably 
related to the trial intervention by the investigator will be reported to the sponsor as 
described in Section 8.4.4. While the investigator is not obligated to actively seek 
this information in former trial subjects, he or she may learn of an SAE through 
spontaneous reporting. 
• 
Any female subject who becomes pregnant while participating in the trial will 
discontinue trial intervention and be withdrawn from the trial.

10.5 Appendix 5: Future Biospecimen Research 
Use/Analysis of DNA 
• 
Genetic variation may impact a subject’s response to trial intervention, susceptibility 
to, and severity and progression of disease. Variable response to trial intervention 
may be due to genetic determinants that impact drug absorption, distribution, 
metabolism, and excretion; mechanism of action of the drug; disease etiology; and/or 
molecular subtype of the disease being treated. Therefore, where local regulations 
and IRB/IEC allow, a blood sample will be collected for DNA analysis from 
consenting subjects. 
• 
DNA samples will be used for research related to tavapadon or PD and related 
diseases. They may also be used to develop tests/assays, including diagnostic tests 
related to tavapadon and PD. Genetic research may consist of the analysis of one or 
more candidate genes or the analysis of genetic markers throughout the genome or 
analysis of the entire genome (as appropriate). 
• 
DNA samples will be analyzed as part of a multi-trial assessment of the genetic 
factors that are involved in response to tavapadon or IMPs of this class to understand 
the trial disease or related conditions 
• 
The results of genetic analyses may be reported in the CSR or in a separate trial 
summary. 
• 
The sponsor will store the DNA samples in a secure storage space with adequate 
measures to protect confidentiality. 
• 
The samples will be retained while research on tavapadon continues but for no 
longer than 15 years or other period as per local requirements.

Introduction 
For all subjects who participate in the substudy of the evaluation the effect of tavapadon 
on the QT interval, please refer to the protocol for the main trial for all other relevant 
requirements. Detailed information on tavapadon may be found in the Single Reference 
Safety Document, which, for tavapadon, is the current version of the Investigator’s 
Brochure. 
10.7.2 
Background and Rationale 
Delay in cardiac repolarization for non-antiarrhythmic drugs, measured as prolongation 
of QT interval duration, can result in an environment that favors development of cardiac 
arrhythmias, especially, torsades de pointes (TdP). Historically, a thorough QT (TQT) 
study has been conducted routinely in drug development programs to understand the risk 
of QT prolongation for new drug molecules. Recently, concentration-QT (C-QT) 
modelling is being recommended as the primary analyses for assessing the QTc interval 
prolongation risk of new drug (Garnett et al, 2018).  
Data from all Phase 1 and Phase 2 trials suggest minimal impact of steady-state 
concentrations for tavapadon on QT interval. However, a formal evaluation of the QT 
prolongation risk in accordance to ICH E14 has not be conducted. The substudy will 
conduct a formal evaluation of the QT prolongation potential for tavapadon in accordance 
with ICH E14 guidance with C-QT modelling as the primary analyses. The current design 
of the main trial, with titration to fixed doses (5 mg QD and 15 mg QD), a placebo 
control, and multiple site visits, will provide necessary concentration and QT data to 
accomplish a formal evaluation of QT-prolongation risk without significant burden on the 
trial subjects. To this extent, all subjects who are enrolled in the trial at US sites will be 
enrolled into the C-QT substudy. Data from the C-QT study will ensure appropriate 
evaluation of QT prolongation risk at therapeutic concentrations. 
10.7.3 
Objective of C-QT Substudy 
The objective of this substudy is: 
• 
To investigate the effect of therapeutic concentration of tavapadon on QT interval 
duration using C-QT modelling  
10.7.4 
Substudy Design 
The substudy has the same overall design as the main trial. The key addition is the 
collection of triplicate ECGs at each visit where PK samples are being collected in order 
to facilitate valid C-QT modelling. The methodology for collection of triplicate ECGs 
intended for C-QT modelling, will be in accordance with the principles laid out in the

ICH E14 Q&A document. Exact details for ECG collection and processing methodology 
are provided in the appropriate protocol-specific manual. 
10.7.5 
Subject Selection 
All subjects who are enrolled in the trial at US sites will participate in the QT substudy if 
they meet all eligibility criteria for the main trial (refer to the main trial sections for any 
additional trial requirements). 
10.7.6 
Study Procedures 
For this substudy, the investigational product is tavapadon. All subjects who are enrolled 
in the trial at US sites will have 3 sets of triplicate ECGs collected at baseline (triplicate 
assessments at 3 predose time points over 45 minutes, ie, at -45, -30, and -15 minutes); 
one set of triplicate ECGs will be collected at all visits when a PK sample will be 
collected (at ~1 hour after dosing on Day 1 and at the Weeks 5, 11, 14, 22, and 27 clinic 
visits). Subjects who are enrolled in the trial at non-US sites will have a similar frequency 
of ECG collection. However, except for the predose time point at the Baseline Visit when 
one set of triplicate ECGs will be obtained, single ECGs will be collected at all time 
points. Data from the non-US sites will not be used for C-QT modelling.  
All other trial procedures will remain unchanged between the main trial and the substudy. 
10.7.7 
Data Analysis 
Detailed methodology for summary and statistical analyses of the data that are collected 
in this substudy will be documented in a separate C-QT Statistical Analysis Plan. The 
C-QT analyses plan will provide details on analytical methodology, predictions based on 
C-QT modelling, and final reporting of analyses. 
10.7.8 
Sample Size Determination 
Sample size determination based on estimates of variability in QT interval for patients 
with PD will be documented separately. Based on the currently available estimates of 
recruitment, approximately 240 subjects are expected to provide data for conduct of 
C-QT modelling across three doses (placebo, 5 mg QD, and 15 mg QD) and wide range 
of concentrations.

Description of Change 
Brief Rationale 
4.1.2 Treatment Period 
Added the following and deleted 
redundant text: 
Titration of tavapadon should be 
guided by absence of tolerability 
issues that are reported as AEs and 
that are of sufficient severity 
resulting in significant dysfunction 
or distress to the subject. Any 
questions regarding tolerability 
issues and titration of tavapadon 
should be directed to the medical 
monitor before adjustments are 
initiated. 
To emphasize that titration of 
tavapadon should be related to 
tolerability issues and to further 
define tolerability issues 
4.4 Definition of Completed 
Subject 
Changed definition of completed 
subject from the contact at the end of 
the Safety Follow-up Period to the 
end of the Treatment Period 
(Week 27) 
Consistency with other sponsor 
protocols that define completed 
subject according to last site 
visit rather than the final contact 
5.1 Inclusion Criteria 
Inclusion Criterion #5: 
Deleted the following: 
...with bradykinesia and motor 
asymmetry 
Added the following: 
Note: Motor asymmetry may or may 
not be present at the time of 
Screening, and is not an explicit 
requirement for inclusion, as long as 
the subject meets the UK 
Parkinson’s Disease Society Brain 
Bank diagnostic criteria based on 
medical history or physical 
examination. 
Clarification regarding presence 
of motor asymmetry with 
respect to inclusion criteria 
 
Added the following: 
Note: Subjects having more than one 
affected relative (Step 2 UK 
Parkinson’s Disease Society Brain 
Bank exclusion criterion) but 
meeting all other criteria consistent 
with the UK criteria will be 
considered to have met eligibility 
criteria for a diagnosis of PD (Litvan 
et al, 2003; Massano and Bhatia, 
2012). 
Consistency with utilization of 
the historical UK criteria in 
current clinical practice, which 
no longer considers having more 
than one affected relative 
exclusory of a diagnosis of 
idiopathic PD based on the more 
recent understanding of the 
complex contributory genetic 
factors 
 
Inclusion Criterion #8: 
Added requirement for minimum 
MDS-UPDRS Part II and Part III 
scores at the Baseline Visit  
To ensure that criteria met at 
Screening continue to be met at 
Baseline

1.2. 
Sample Size Considerations 
A sample size of 174 subjects per group will provide 90% power to detect a change in the 
primary outcome measure (change from baseline to endpoint in the MDS-UPDRS Parts II and III 
combined score) of 4 points, with a standard deviation of 9, 2-sided alpha level = 0.025, and 
assuming a 27% dropout rate. 
In the event of higher than anticipated early terminations due to COVID-19 or other reasons, 
Cerevel may extend enrollment in order to maintain the planned statistical power. 
1.3. 
Measures to Minimize Bias: Randomization and Blinding 
1.3.1. 
Subject Assignment to Treatment 
All subjects will be centrally randomized in a 1:1:1 ratio to 1 of 3 treatment arms (tavapadon 
5 mg QD, tavapadon 15 mg QD, or placebo) at the Baseline Visit via an Interactive Voice 
Response System/Interactive Web Response System (IVRS/IWRS), according to a 
computer-generated randomization scheme. Randomization will be stratified by concurrent use 
of allowed antiparkinsonian medication (MAO-B inhibitor). 
1.3.2. 
Blinding 
The tavapadon and placebo tablets will be identical in appearance and will be packaged in 
identically appearing blister cards. All subjects will take 3 tablets once daily of IMP throughout 
the Treatment Period, either all tavapadon tablets, all placebo tablets, or a combination of 
tavapadon and placebo tablets. Tablets will be packaged to allow dosage adjustments to be made 
without breaking the trial blind. 
Treatment assignments will be blinded to the investigators and other trial site personnel, the 
subjects, and all sponsor personnel who are involved in the conduct of the trial (including trial 
monitoring, data management, and data analysis). Access to the treatment codes will be restricted 
to personnel who are responsible for generating and maintaining the randomization code, 
packaging the IMPs, operating the IVRS/IWRS, analyzing the PK blood samples, or reporting 
serious adverse events (SAEs) or adverse events of special interest (AESI) to regulatory 
agencies. 
Documentation of breaking the blind should be recorded in the subject’s medical record and 
eCRFs, with the reason for breaking the blind, the date and time the blind was broken, and the 
names of the personnel involved. Once the blind is broken for a subject, treatment with the IMP 
may not be reinitiated for that subject. 
1.4. 
Treatment Period 
The dose of tavapadon will be titrated to either 5 mg QD or 15 mg QD and then maintained for 
the duration of the 27-week Treatment Period. The titration schedule, as shown in Table 1, will 
be used for all subjects who are randomized to receive tavapadon. Subjects will take 3 tablets of 
investigational medicinal product (IMP), either all tavapadon tablets, all placebo tablets, or a 
combination of tavapadon and placebo tablets, throughout the trial to maintain the trial blind.

No deviations in the titration schedule up through 
 will be allowed. Titration of tavapadon 
should be guided by absence of tolerability issues that are reported as AEs and that are of 
sufficient severity resulting in significant dysfunction or distress to the subject. Any questions 
regarding tolerability issues and titration should be directed to the medical monitor before 
adjustments are initiated. Subjects who cannot achieve or tolerate the dose at 
 (5 mg QD) 
or 
 (10 mg QD) must be discontinued from the trial. 
Starting on Day 74, subjects who achieve but do not tolerate the dose at 
 may go back to 
the dose at 
 Subjects may remain at the 
 dose or will be permitted a one-time 
rechallenge back to the
 dose if needed for symptomatic control. Subjects must receive 
the 
 dose for at least 7 days before a rechallenge to the 
 dose is attempted. Subjects 
who are unable to tolerate the 
 dose upon rechallenge will be discontinued from the trial.

KEY ASSESSMENTS AND DERIVATIONS 
3.1. 
Efficacy Assessments 
3.1.1. 
Movement Disorder Society-Unified Parkinson’s Disease Rating Scale (MDS-
UPDRS)  
The MDS-UPDRS (Goetz et al, 2008) is a multidimensional scale that assesses the motor and 
nonmotor impacts of PD across 4 parts. The scale is completed using a combination of physician 
and patient assessments and a collection of information from the patient or caregiver. Each 
evaluation item is rated on a scale from 0 to 4 on which 0 = normal, 1 = slight, 2 = mild, 
3 = moderate, and 4 = severe. This trial incorporates Part I, II, and III assessments for the 
specific trial population. 
3.1.1.1. 
Part I Score 
Part I of the MDS-UPDRS focuses on the non-motor aspects of experiences of daily living. The 
MDS-UPDRS Part I score value for a given visit is obtained as the sum of all 13 evaluation items 
in the MDS-UPDRS Part I subscale, including the 6 items which are rated by the Physician. 
Valid values for the sum are integers from 0-52, with 0 being the least severe and 52 being the 
most severe. 
3.1.1.2. 
Part II Score 
Part II of the MDS-UPDRS focuses on the motor aspects of experiences of daily living. The 
MDS-UPDRS Part II score value for a given visit is obtained as the sum of all 13 evaluation 
items in the MDS-UPDRS Part II subscale. Valid values for the sum are integers from 0-52, with 
0 being the least severe and 52 being the most severe. 
3.1.1.3. 
Part III Score 
Part III of the MDS-UPDRS is the motor evaluation comprises 18 items that are assessed by the 
investigator (resulting in 33 scores by location and lateralization). Valid values for the sum are 
integers from 0-132, with 0 being the least severe and 132 being the most severe.   
3.1.1.4. 
Handling of Missing Items from MDS-UPDRS 
If individual items are missing from a given part of the MDS-UPDRS, the corresponding total 
score may be generated by prorating the response if the number of missing items is not 
excessive. For Part I and Part II assessments, only a single missing item score is allowable. For 
Part III, up to 7 missing item scores are allowable. To prorate the value, the following formula is 
utilized

Version 1.0: 31 July 2024
 
Where n is the number of non-missing items, j1-jn represents the n non-missing values reported 
by the subject for the given subscale, and U is the number of total items in the subscale. If more 
than the allowable items are missing, the total score will be treated as missing. 
3.1.1.5. 
Part II + III Combined Score 
The MDS-UPDRS Part II + III Combined Score is defined as the sum of the total scores for Part 
II and Part III within a given assessment (i.e., to have a Part II + III Total score, the subject must 
have a non-missing Part II total score and a non-missing Part III total score on the same date). 
The Part II + III Combined Score will be derived after any imputation of missing values within 
each individual total score.  
3.1.1.6. 
Part I, Part II, and Part III Combined Score 
The MDS-UPDRS Part I, Part II, and Part III Combined Score is defined as the sum of the total 
scores for Parts I, II, and  III within a given assessment (i.e., to have a Part I, Part II, and Part III 
Combined score, the subject must have a non-missing Part I total score, a non-missing Part II 
total score, and a non-missing Part III total score on the same date). The Part I, Part II, and Part 
III Combined Score will be derived after any imputation of missing values within each individual 
total score. 
3.1.2. 
Patient Global Impression of Change (PGIC) 
The PGIC is the patient-reported outcome in a 7 point scale to rate how much the patient's illness 
has improved or worsened relative to the baseline state at the beginning of the intervention. The 
qualitative assessment of meaningful change is determined by the patient in response to the 
question, “Compared to your condition at the beginning of treatment, how much has your 
condition changed?” Scores are: 1=very much improved; 2=much improved; 3=minimally 
improved; 4=no change; 5=minimally worse; 6=much worse; and 7=very much worse. 
3.1.3. 
Clinical Global Impression – Severity of Illness (CGI-S) 
The CGI-S scale is a 7 point scale that requires the clinician to rate the severity of the patient’s 
illness at the time of the assessment relative to the clinician’s experience with patients who have 
the same diagnosis. Raters select one response based on the following question: “Considering 
your total clinical experience with this particular population, how ill is the patient at this time?” 
Scores are: 1=normal, not at all ill; 2=borderline ill; 3=mildly ill; 4=moderately ill; 5=markedly 
ill; 6=severely ill; and 7=among the most extremely ill patients. 
3.1.4. 
Clinical Global Impression – Improvement (CGI-I) 
The CGI-I is a 7 point scale that requires the clinician to assess how much the patient's illness 
has improved or worsened relative to the baseline state at the beginning of the intervention. 
Raters select one response based on the following question, “Compared to your patient’s 
condition at the beginning of treatment, how much has your patient changed?” Scores are: 
1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally 
worse; 6=much worse; and 7=very much worse.

3.1.5. 
39-Item Parkinson’s Disease Questionnaire (PDQ-39) Score 
The 39-item Parkinson’s Disease Questionnaire (PDQ-39) measures 39 items, which assess 
8 domains of health: mobility (10 items), activities of daily living (6 items), emotional well being 
(6 items), stigma (4 items), social support (3 items), cognitions (4 items), communication 
(3 items), and bodily discomfort (3 items) (Peto et al, 1998). Each item is scored on the 
following scale: 0=never, 1=occasionally, 2=sometimes, 3=often, and 4=always. Items in each 
subscale and the total scale can be summarized into an index and transformed linearly to a scale 
from 0 (perfect health as assessed by the measure) to 100 (worst health as assessed by the 
measure).  
A dimension score is calculated using the following formula: 

=
=
n
j
jt
n
d
1
4
*
1
*100 
where n is the number of items in the dimension, and tj is the jth item in the dimension. This 
transforms the scale linearly from 0 (perfect health as assessed by the measure) to 100 (worst 
health as assessed by the measure). If items are missing within a domain, the n in the above 
formula will be changed to the number of items in the dimension that the subject answered if at 
least half of the questions in the domain were answered. Otherwise, a domain and summary 
index will not be calculated.  
A summary index called PDQ-39 SI, is calculated as the average of the 8-dimension scores. 
3.1.6. 
EuroQol 5 Dimension 5 Level  
The EuroQol 5 Dimension 5 Level (EQ 5D 5L) is a patient-reported outcome that measures 
health in 5 dimensions. It is a widely used survey instrument for measuring economic 
preferences for health states, is applicable to a wide variety of health conditions and treatments, 
and provides a simple descriptive profile and a single index value for health status 
(Herdman et al, 2011). The EQ 5D 5L consists of a descriptive system and a visual analog scale 
(VAS). 
The descriptive system comprises 5 dimensions: mobility, self care, usual activities, 
pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight 
problems, moderate problems, severe problems, and extreme problems. The patient is asked to 
indicate his or her health state by ticking the box next to the most appropriate statement in each 
of the 5 dimensions (Section 9.2). This decision results if a 1 digit number that expresses the 
level that was selected for that dimension. The digits for the 5 dimensions are combined into a 
5 digit number that describes the patient’s health state. For example, 11122 would represent the 
health state for someone who has no problems with mobility, self-care, or usual activities, but 
who has slight pain or discomfort and slight anxiety or depression. For each subject and visit, the 
5-digit health state will be converted into a single summary index, the EQ-5D Index, using the 
EQ-5D-5L Index calculator with US value set (van Hout, Janssen et al. 2012; Section 9.9).

The EQ VAS records the patient’s self-rated health on a 20-cm vertical visual analogue scale 
(VAS). The VAS is numbered from 0 to 100 with 0 meaning ‘the worst health you can imagine’ 
and 100 meaning ‘the best health you can imagine’. This information can be used as a 
quantitative measure of health outcome that reflects the patient’s own judgement. 
The EQ-5D-5L asks respondents to simply ‘mark an X on the scale to indicate how your health 
is TODAY’ and then to ‘write the number you marked on the scale in the box below’. 
3.1.7. 
Schwab and England Activities of Daily Living (ADL) Scale  
The Schwab and England ADL scale is a method of assessing a person’s ability to perform daily 
activities in terms of speed and independence through a percentage figure. The clinician 
determines the rating according to the following criteria, with 100% indicating total 
independence and 0% indicating a state of complete dependence: 
100% Completely independent. Able to do all chores without slowness, 
difficulty, or impairment. Essentially normal. Unaware of any difficulty. 
90% 
Completely independent. Able to do all chores with some degree of 
slowness, difficulty, and impairment. May take twice as long. Beginning 
to be aware of difficulty 
80% 
Completely independent in most chores. Takes twice as long. Conscious 
of difficulty and slowness. 
70% 
Not completely independent. More difficulty with some chores. Three to 
four times as long in some. May spend a large part of the day with chores. 
60% 
Some dependency. Can do most chores, but exceedingly slowly and with 
much effort. Errors; some impossible. 
50% 
More dependent. Help with half, slower, etc. Difficulty with everything. 
40% 
Very dependent. Can assist with all chores, but few alone 
30% 
With effort, now and then does a few chores alone or begins alone. Much 
help needed 
20% 
Nothing alone. Can be a slight help with some chores. Severe invalid 
10% 
Totally dependent, helpless. Complete invalid. 
0% 
Vegetative functions such as swallowing, bladder and bowel functions are 
not functioning. Bedridden.

Safety Assessments 
3.2.1. 
Questionnaire for Impulsive-Compulsive Disorders in Parkinson’s Disease 
Rating Scale (QUIP-RS) Scores 
The QUIP RS has 4 primary questions that pertain to commonly reported thoughts, urges/desires, 
and behaviors associated with impulse control disorders (ICDs), each of which is applied to 
4 ICDs (compulsive gambling, buying, eating, sexual behavior) and 3 related disorders 
(medication use, punding, and hobbyism).

Version 1.0: 31 July 2024
 
Each question is scored using a 5 point Likert scale (score, 0=never [not at all], 1=rarely 
[infrequently or 1 day/week], 2=sometimes, 3=often, 4=very often). Scores for each ICD and 
related disorder range from 0 to 16, with a higher score indicating greater severity (frequency) of 
symptoms.  
The total QUIP-RS score for all ICDs and related disorders combined ranges from 0 to 112. In 
case of missing item scores, the missing value will be replaced by the average of non-missing 
scores at the same visit from the same subject. In case all item scores in any subcategory are 
missing, the total score will be set as missing. 
3.2.2. 
Epworth Sleepiness Scale (ESS) Total Score 
The ESS scale is used to determine the level of daytime sleepiness. There are 8 situations listed 
for which patients rate their likelihood of dozing or sleeping (0=no chance of dozing, 1=slight 
chance of dosing, 2=moderate chance of dosing, or 3=high chance of dozing). The total score is 
the sum of 8 item scores and can range between 0 and 24. The higher total score indicates the 
higher level of daytime sleepiness. A score of 10 or more is considered sleepy, and a score of 18 
or more is very sleepy.   
In case of missing item scores from the ESS, the missing value will be replaced by the average of 
non-missing scores at the same visit from the same subject. In case all item scores are missing, 
the total score will be set as missing. 
3.2.3. 
Adverse Event (AE) 
An AE is defined as any untoward medical occurrence in a patient or clinical trial subject, 
temporally associated with the use of trial intervention, whether considered related to the trial 
intervention. NOTE: Signs and symptoms and/or abnormal laboratory test result indicating a 
common underlying pathology/diagnosis should be reported as a single AE.  
All adverse events will be recorded on the ADVERSE EVENTS eCRF. Adverse events with 
missing severity will have the severity imputed as ‘Severe’ for the AE tabulations. Adverse 
events with missing relationship to IMP will have the relationship imputed as ‘Related’ for the 
AE tabulations if the AE started on or after the first dose of IMP. However, in the data listings 
these missing severity and/or relationship will be presented as missing. 
3.2.3.1. 
Adverse Event of Special Interest (AESI)  
For this study, any AEs related to abuse potential, AEs involving MHIs, abnormal liver function 
tests with a value >3 × ULN for ALT or AST and >2 × ULN for total bilirubin within the same 
visit, a value of >3 × ULN for ALT or AST and clinical jaundice, an AE leading to the 
discontinuation of IMP or from the study will be considered AESIs. These events will be noted 
by the investigator in the ADVERSE EVENTS eCRF. 
3.2.3.2. 
Treatment-emergent Adverse Event (TEAE) 
Any event reported on the eCRF that occurs on or after the initiation of IMP until the end of AE 
reporting period per protocol is considered treatment emergent.

Additionally, it is assumed that an Adverse Event which was reported to have started on Day 1 
without an associated onset time is assumed to be treatment emergent. 
3.2.4. 
Clinical Safety Laboratory Assessments 
The clinical laboratory tests as listed in the protocol will be performed in accordance with the 
laboratory manual and the Schedule of Assessments. All results, including repeats, will be 
included in the laboratory reports. The investigator must review the laboratory report, document 
this review, and record any clinically relevant changes occurring during the trial in the AE 
section of the eCRF. 
3.2.4.1. 
Treatment-emergent Laboratory Abnormality and Toxicity 
A treatment-emergent laboratory abnormality is defined as value outside the normal range which 
occurs on or after the start of IMP and up to the last contact following discontinuation of IMP. 
A treatment-emergent laboratory toxicity is defined as an increase of at least one abnormality 
severity grade (specifications in Section 9.8) from the baseline assessment at any post baseline 
visit which occurs after the first administration of IMP and through last test results of the study. 
If a laboratory assessment obtained on Day 1 with unknown collection times will be assumed to 
be an assessment prior to the initiation of IMP. If the relevant baseline assessments are missing 
for a given subject, any post-baseline severity grade at 1 or more is considered a 
treatment-emergent laboratory toxicity. 
3.2.5. 
Columbia-Suicide Severity Rating Scale (C-SSRS) 
Suicidality will be monitored during the trial using the C-SSRS. It was designed to quantify the 
severity of suicidal ideation and behavior.  
This trial will use the “Baseline/Screening” and “Since Last Visit” versions of the scale. The 
“Baseline/Screening” version, which assesses the lifetime experience of the subject with suicide 
events and suicidal ideation and the occurrence of suicide events or ideation within a specified 
time period prior to entry into the trial, will be completed for all subjects at screening to 
determine eligibility and confirmed at baseline. Any subject with active suicidal ideation or 
suicidal behaviors within the last 6 months, suicidal behaviors within the last 2 years, or who in 
the clinical judgment of the investigator presents a serious risk of suicide should be excluded 
from the trial. 
The “Since Last Visit” C-SSRS form will be completed at all visits after screening and baseline. 
The investigator will review the results of the “Since Last Visit” C-SSRS during the trial to 
determine whether it is safe for the subject to continue in the trial. If a subject demonstrates 
potential suicidal ideation associated with actual intent or method or plan as indicated by “YES” 
answers on item 4 or 5 of the C-SSRS, the investigator will evaluate whether a risk assessment 
by a qualified mental health professional (or the investigator alone if the investigator is a 
qualified mental health professional) is needed and whether the subject should continue in or be 
discontinued from the trial. 
Details of C-SSR categories as well as definition of treatment emerging events are provided in 
Section 9.3.

3.2.6. 
Vital Signs 
Vital signs include systolic and diastolic blood pressures, heart rate, and body temperature. 
Duplicate measurements of blood pressure and heart rate will be obtained supine (after 5 minutes 
of rest) and 1 measurement of blood pressure and heart rate will be obtained on standing 
(2 minutes after rising from supine to standing). The duplicate values will be individually 
recorded, and the values will be averaged by the sponsor for the time point assessment. Body 
temperature will be obtained once, at the time of the first blood pressure measurement. 
3.2.7. 
Electrocardiograms 
Single or triplicate 12 lead ECGs will be obtained during the trial. All ECG recordings be 
obtained after the subject has been supine and at rest for at least 5 minutes. A triplicate set of 
ECGs is 3 consecutive ECGs collected 1 to 2 minutes apart over a 5 minute period. 
A single ECG will be obtained at the Screening Visit. For US sites, three sets of triplicate ECGs 
will be obtained during the 45 minutes before administration of the first dose of IMP on Day 1 
(at -45, -30, and -15 minutes), and a single set of triplicate ECGs will be obtained ~1 hour after 
administration of the first dose of IMP on Day 1, just prior to the time of collection of the PK 
blood sample. One set of triplicate ECGs will be obtained at the Weeks 5, 11, 14, 22, and 27 
clinic visits, just prior to the time of collection of the PK blood sample. The triplicate ECG 
information from US sites will be used in a C-QT analysis with results reported separately. For 
non-US sites, one set of triplicate ECGs will be obtained before administration of the first dose 
of IMP on Day 1, and a single ECG will be obtained ~1 hour after administration of the first dose 
of IMP on Day 1, just prior to the time of collection of the PK blood sample. Single ECGs will 
be obtained at the Weeks 5, 11, 14, 22, and 27 clinic visits, just prior to the time of collection of 
the PK blood sample. A central ECG service will be used for reading all ECGs to standardize 
interpretations for the safety analysis. 
3.2.8. 
Prior Medications, Concomitant Medications and Medications Taken Post Last 
Dose of IMP 
Prior medications are those medications taken prior and ended prior to the initiation of IMP. 
These medications will be captured in the CONCOMITANT MEDICATIONS eCRF.  
Concomitant medications are those medications taken on or after the initiation of IMP. These 
medications include those medications started before the initiation of IMP and continuing post 
Day 1. Medications that start after the last dose of IMP until the end of protocol-specified 
reporting period will be classified as taken post last dose and will not be considered concomitant. 
These medications will be recorded in the eCRF. The investigator will record all medications and 
therapies (including vaccines, over-the-counter or prescription medicines, vitamins, and/or herbal 
supplements) that are used by the subject from 30 days before the informed consent form (ICF) 
is signed through the end of the Safety Follow-up Period (Week 31 or early termination). The 
investigator will also record all medications and therapies taken or received by a subject for 
treatment of an AE or that cause an AE through Week 31 or early termination.

A complete physical and neurological examinations will be conducted at screening and at the end 
of treatment visit (Visit 11 or early termination visit). Any condition present post-baseline 
physical or neurological examination that was not present at the baseline examination should be 
documented as an AE and followed to a satisfactory conclusion. 
3.3. 
Pharmacokinetics 
Blood samples for measurement of plasma concentrations of tavapadon and CVL-0000053, its 
major metabolite, will be collected ~1 hour after administration of the first dose of IMP on Day 1 
and at the clinic visits at the end of Weeks 5, 11, 14, 22, and 27. 
Drug concentration information will not be reported to investigative sites, clinical database or 
any blinded study personnel until the trial has been completed and unblinded.

DATA CONVENTIONS AND VISIT WINDOWS 
4.1. 
Data Conventions 
4.1.1. 
Age 
Age is the age at the time of informed consent and is as captured on the eCRF (note: date of birth 
is not captured on the eCRF). 
4.1.2. 
Day 1  
Day 1 is the day IMP is first initiated. 
4.1.3. 
Endpoint 
Endpoint as defined as the primary time point for the efficacy assessments is Week 26. 
4.1.4. 
Study Day of an Event 
Study day of an event is defined relative to Day 1 as: 
 
Study Day = event date – date of Day 1 (+ 1, if event date ≥ date of Day 1). 
This calculation will result in negative study days for an event occurring prior to the start of IMP 
and positive study days for an event on or after the start of IMP.  There will be no Day 0 value to 
match the schedule of events. 
4.1.5. 
Days on Study 
Days on Study is the number of days from Day 1 to the date of study completion or early 
termination as recorded on the END OF STUDY eCRF. 
4.1.6. 
Days on IMP 
Days on IMP is the number of days from Day 1 to the date of last dose of IMP as recorded on the 
EXPOSURE eCRF. 
4.1.7. 
Baseline Value 
For purposes of analysis, the baseline value of a given assessment is defined as the last value 
obtained prior to initiation of IMP. Should the Day 1 visit value be obtained after the first dose of 
IMP or if this value is not available at Day 1, the most recent value obtained prior to the first 
dose of IMP will be used for the baseline value.  
For US subjects with triplicate ECGs taken at 3 pre-dose timepoints, the baseline value will be 
defined as the average of the available pre-dose ECG values (i.e. triplicate ECGs at -45 minutes 
pre-dose, -30 minutes pre-dose, and -15 minutes pre-dose). For non-US subjects, the baseline 
value will be defined as the average of the available pre-dose ECG values. Scheduled records 
will be selected over unscheduled records if a tie breaker is needed.

For blood pressure and heart rate measurements, baseline is defined as the average of the 
duplicates at the last visit prior to the IMP administration. If no duplicate is available, the last 
non-missing value prior to the initiation of IMP will be used. 
4.1.8. 
Change from Baseline 
Change from baseline for a given variable is defined as the value on a given Study Day (Time 
Point) minus the Baseline Value. 
4.1.9. 
Orthostatic Change 
Orthostatic change is calculated as the difference in the standing value from the supine value 
(i.e., supine value – standing value). If an average value is available at a given visit and date, it 
will be used for the calculation of orthostatic change. If an average value is not available, the 
individual record obtained on a given visit and date will be used. 
4.1.10. 
Duration of Titration Phase 
The duration of the titration phase will be calculated as the days in 
 of the dosing 
schedule. 
4.1.11. 
Duration of Maintenance Phase 
The duration of the maintenance phase will be calculated as the days in 
 of the dosing 
schedule. 
4.1.12. 
Average Dose of Titration Phase 
The average dose of the titration phase will be calculated as the sum of the milligrams of study 
drug taken in 
 of the dosing schedule divided by the duration of days in the titration 
phase. 
4.1.13. 
Average Dose of Maintenance Phase 
The average dose of the maintenance phase will be calculated as the sum of the milligrams of 
study drug taken in 
 of the dosing schedule divided by the duration of days in the 
maintenance phase. 
4.1.14. 
Compliance with Study Drug 
Accountability and compliance will be assessed through self-reporting by the subject and by 
tablet count at each clinic visit. For analysis purposes, evaluation of compliance will be based on 
the site assessment of compliance as recorded on the DRUG ACCOUNTABILITY eCRF. 
Compliance will be calculated as a percentage based on the total number of tablets taken relative 
to the total expected number of tablets based on days on study. If a kit was lost and return 
information was available, the return information will be used for the compliance calculation. If 
a kit was lost and no return information was available, it is assumed that the tablets were not 
taken for the compliance calculation. If return information is not available and the kit was not 
lost, it is assumed that the tablets were taken for the compliance calculation.

If a kit was redispensed and the number of tablets redispensed is not available, it is assumed that 
the number of tablets that were partially returned were redispensed for the compliance 
calculation. 
4.1.15. 
Handling of Incomplete or Missing Dates Associated with an Event 
An incomplete date occurs when the exact date an event (e.g. an adverse event) occurred or 
ended cannot be obtained from a subject. The database contains data fields for month, day, and 
year. A date is incomplete if at least one of these three fields is not known.  
For many of the planned analyses, a complete date is necessary to determine if the event should 
be included in the analysis (e.g. if the event is treatment-emergent) or to establish the duration of 
an event. In such cases, incomplete dates will be imputed as described below. 
For the purposes of handling partially reported start and stop dates for an event the following 
algorithm will be applied: 
• Missing start day, but month and year present: 
If the event occurs same month and year as the occurrence of IMP, then the start day 
of the event will be assigned to the day of first dose of IMP (i.e., Day 1). 
Otherwise the start day will be set to the first day of the month. 
• Missing start day and month, but year present: 
If event occurs in the same year as IMP, then the start date of the event will be 
assigned to Day 1. 
Otherwise the start day and month will be set to 01 January. 
• In the unlikely event of a completely missing start date (year not present), the start 
date will be imputed as Day 1. 
• Missing end day, but month and year present: 
The day will be set to the last day of the month. 
• Missing end day and month, but year present: 
The end day and month will be set to the date of study completion. However, if study 
completion year is greater than the year of the event, then the day and month will be 
set to 31 December. 
• Missing all components of an end date and the event is not marked as ongoing: 
The event will be considered as ‘ongoing’ and will be considered treatment-emergent 
if the start date is on or after Day 1. 
If any imputed start date causes the start date to occur after the end date, the end date will be 
used for the imputation of the start date. If any imputed end date causes the end date to occur 
prior to the start date of the event, the start date of the event will be used for the imputation of the 
end date. If the imputed date is later than the date of study withdrawal, then the date of study 
withdrawal will be used to impute the date in question. In subject data listings, start and stop date 
of events will be displayed as reported on the eCRF without imputed dates.

For the purposes of handling partially reported diagnosis date of Parkinson’s disease, the 
following algorithm will be applied to randomized subjects: 
• Missing day, but month and year present: 
If the diagnosis date occurs same month and year as the occurrence of the subject’s 
screening date, then the day of the diagnosis date will be assigned to the day of the 
subject’s screening date.  
Otherwise the diagnosis day will be set to the first day of the month. 
• Missing day and month, but year present: 
If the diagnosis date occurs in the same year as the occurrence of the subject’s 
screening date, then the diagnosis date will be assigned to the subject’s screening 
date. 
Otherwise the diagnosis day and month will be set to 01 January. 
• In the event of missing year or a completely missing diagnosis date, the diagnosis 
date will be assigned to the subject’s screening date. 
In subject data listings, diagnosis dates will be displayed as reported on the eCRF without 
imputed dates. For screen failures, no imputation will be made to the date of diagnosis of 
Parkinson’s disease. 
4.1.16. 
Handling of Alphanumeric Data  
Should there be instances where a clinical laboratory parameter is reported with imbedded 
non-numeric characters, as for example, “<0.1” or “>10”, the data will be imputed as described 
below for quantitative summaries. The actual alphanumeric values as reported in the database 
will be presented in data listings. 
• The values < LLN will be replaced with ½ the value of the lower limit. For example, 
“< 0.1” will be replaced with 0.05 if the LLN is 0.1.   
• The values > ULN will be replaced by values of increased precision by one level. For 
example, “>0.1” will be imputed to “0.11” if the ULN is 0.1, and “>10” will be 
imputed to “10.1” if the ULN is 10. 
Additionally, in the event of the upper limit of normal (ULN)/lower limit of normal (LLN) 
reported as alphanumeric (e.g., ‘<5’, ‘≤5’, ‘>5’, ‘≥5’), the determination of the laboratory 
abnormality severity grade will be based on the convention on the ULN and LLN below: 
• If the ULN is in the form of ≤5, only the numeric part will be used for determining 
the abnormality severity grade of the test results (i.e., the ULN is set to 5). If the ULN 
is in the form of <5, the numeric value of the ULN will be decreased by two levels of 
precision in the direction of the symbol (i.e., the ULN is set to 4.99).

• If the LLN is in the form of ≥5, only the numeric part will be used for determining the 
abnormality severity grade of the test results (i.e., the LLN is set to 5). If the LLN is 
in the form of >5, the numeric value of LLN will be increased by two levels of 
precision in the direction of the symbol (i.e., the LLN is set to 5.01). 
4.2. 
Visit Windows 
Data collected longitudinally across visits will be summarized and analyzed by visit.  
Laboratory data will be presented according to the nominal visit as collected from the eCRF or 
laboratory data unless the visit is an early termination or unscheduled visit. Early termination and 
unscheduled visits will be assigned visit windows based on the study day completed according to 
Table 3. Baseline will be determined per the baseline definition in Section 4.1.7. Other 
assessment data, including efficacy assessments data, will be mapped to the appropriate time 
point based on the window as defined in Table 3 from Baseline to Week 22 to appropriately 
captured time of assessment in cases of visit schedule variations. Due to the short interval 
between Visit 10 (Week 26) and Visit 11 (Week 27), data obtained at the nominal visit at this 
two time points will be used with the exception of early termination/unscheduled visits.

If assessments are collected multiple times within a given visit window the result closest to the

same distance to the target day, the later value will be used. If a subject has multiple non-missing 
values on the same date, the average record will be used (if applicable). If there are multiple 
average records on the same date, the average based on the scheduled measurements will be 
used. If no averages exist, the last record as determined by the time collected will be used.

STATISTICAL ANALYSIS METHODS 
5.1. 
General Considerations 
Descriptive statistical methods will be used to summarize the data from this trial, with statistical 
testing performed for the efficacy endpoints. Unless stated otherwise, the term “descriptive 
statistics” refers to number of subjects (N), number of observations (n), arithmetic mean, median, 
standard deviation (SD), geometric mean and coefficient of variation (CV%) (for concentration 
data only), first quartile (Q1), third quartile (Q3), minimum, and maximum for continuous data, 
and frequencies and percentages for categorical data. Certain figure presentations will include 
the standard error of the mean (SE). The term “treatment group” refers to treatment assignment: 
placebo, tavapadon 5 mg, and tavapadon 15 mg. All data collected from subjects who sign the 
informed consent form, including screen failures, will be included in data listings. Unless 
otherwise noted, the data listings will be sorted first by treatment group and subject number and 
then by date within each subject number. 
The number and proportion of missing visits and key assessments due to COVID-19 control 
measures and the frequency of remote assessments performed due to COVID-19 restrictions will 
be tabulated by treatment, visit, and assessment as well as the overall number and proportion of 
subjects with any such missing visits, assessments, or remote visits in each treatment group. 
The statistical analyses will be conducted with the SAS® software package version 9.4 or higher.

5.4.
Multiplicity Adjustment
A graphical approach depicted below is utilized to illustrate the hierarchal multiple testing 
strategy planned for the hypotheses described above to control the overall Type I error rate.  The 
primary endpoint of the tavapadon 15 mg QD will be compared with that of placebo (H1) with 
full of 0.05 and, if successful, the available will be passed along fully (r=1) to the 
comparison of the primary endpoint of tavapadon 5 mg QD with placebo (H2). If H2 is 
successful, the full will be available to the secondary hypothesis H3. The sequence will 
continue until H6 or until the sequence breaks with no remaining available.

5.5. 
Strata and Covariates 
The randomization is stratified by concurrent use of MAO-B inhibitor. This factor is planned to 
be included as a covariate in the efficacy analyses. However, due to isolated administrative errors 
at a few sites during randomization through IRT system, 15 subjects were randomized to the 
incorrect strata (3 non-MAO-B inhibitor users were randomized to the MAO-B inhibitor use 
stratum and 12 MAO-B inhibitor users were randomized to the non-user stratum; details in 
Section 9.7). The actual MAO-B inhibitor use status, as recorded in eCRF, will be used as a 
covariate instead of the randomization strata in these cases.  
The baseline value of each efficacy variable (if applicable) will also be included as a covariate in 
the efficacy analyses. 
5.6. 
Subject Disposition, Demographic and Baseline Characteristics 
Subject disposition will be based on the ITT population with tabulation of the number of subjects 
who complete the study and the number of discontinued and from the study and the reasons by 
treatment group. Additionally, the number of days on study will be summarized.  
Tabulation of subject randomization by country and site will be presented for the ITT population 
and for completed subjects. A listing of randomization number, subject, treatment randomized, 
country, and site will be provided. Further tabulation by region (United States, Non-US) and 
country will also be presented. Subject disposition data will also be tabulated for all subjects 
screened to include the number of subjects screened, the number of screen failures, and the 
reason for screen failure. 
Kaplan-Meier plots will be used to assess time to discontinuation of study treatment, time to 
discontinuation of treatment due to adverse events, and time to discontinuation of treatment due 
to subject withdrawal. The complete subjects or subjects discontinued treatment for reasons other 
than adverse events and withdrawal of consent will be censored at the time of end of treatment 
for the respective KM analyses. If a subject died without treatment discontinuation date 
information, date of death will be used as the time of discontinuation. 
Number of subjects in each analysis population set will be summarized. 
Demographic data and baseline characteristics including age, age categorical distribution, sex, 
childbearing potential, race, ethnicity, height at screening, weight at screening and at baseline, 
BMI at screening and at baseline, MAO-B inhibitor use at baseline, history of Parkinson's 
disease (including years from initial diagnosis), Montreal Cognitive Assessment (MoCA) total 
score, Modified Hoehn & Yahr assessment at screening, MDS-UPDRS (all parts, Part I + Part II 
+ Part III combined, and Part II + III combined) score at baseline, and CGI-S at baseline will be 
summarized using descriptive statistics for the ITT population. Further tabulation by region and 
country will also be presented. 
5.7. 
Medical and Psychiatric History 
Medical and psychiatric history events will be mapped to a Medical Dictionary for Regulatory 
Activities (MedDRA) version 27.0 or higher preferred term and system organ class.

Exposure to Treatment 
The number of days on study drug, reasons for premature discontinuation of IMP, treatment

Primary Efficacy Analysis 
5.9.1. 
Primary Estimand 
The key research question for the primary endpoint will be addressed with an estimand based on 
the following attributes:  
1) 
Treatments: treatments as randomized regardless of the actual treatment received or the 
final dose level achieved following the titration steps. 
2) 
Target study population of interest: subjects in the modified intent-to-treat (mITT) 
population regardless the completion status of dose titration steps. 
3) 
Endpoint (variable) of interest: change from baseline to Week 26 in the MDS-UPDRS 
Part II + III Combined Score. 
4) 
Population level summary of interest: estimated mean difference between each tavapadon 
dose group and placebo group in the endpoint of interest. 
5) 
Strategy for Intercurrent events (ICEs): a hypothetical strategy will be used to address 
intercurrent events (ICEs) of potential death, treatment discontinuations, missed 
visits/assessments, and start of prohibited concomitant Parkinson’s disease medications. 
The data after treatment discontinuations or after the start of prohibited Parkinson’s 
disease concomitant medications will be censored under the hypothetical strategy. 
Prohibited Parkinson’s disease concomitant medications are defined as medications in 
ATC classifications of ADAMANTANE DERIVATIVES, DOPAMINE AGONISTS, 
MONOAMINE OXIDASE B INHIBITORS, OTHER ANTIPARKINSON DRUGS, 
OTHER DOPAMINERGIC AGENTS, or DOPA AND DOPA DERIVATIVES that are 
started after the first dose of IMP and prior to the last dose of IMP with duration of use 
7 days or more. The hypothetical strategy allows the study to assess the effect of 
tavapadon treatment without the confounding effect of prohibited concomitant 
Parkinson’s disease treatments.

5.9.2. 
Main Analytical Approach 
The change from baseline to each study visit in MDS-UPDRS Part II and III combined score will 
be summarized by visit and treatment group. A mixed model repeated measures (MMRM) 
analysis will be used to analyze the data from all post-randomization timepoints up to Week 27 
with fixed effect of treatment group, visits, interaction between treatment group and visit, and 
baseline MAO-B inhibitor use. The baseline value of MDS-UPDRS Part II and III combined 
score will also be included as a covariate. Subject will be included as a random effect. An 
unstructured covariance structure will be used for the repeated measures. If the unstructured 
covariance matrix results in convergence issue, the heterogeneous Toeplitz covariance structure 
followed by the heterogeneous first-order autoregressive (AR(1)) structure will be used. The 
Kenward-Roger approximation will be used to estimate the denominator degrees of freedom. 
The difference between each active dose and placebo at the endpoint visit (Week 26) will be 
estimated based on the Least Squares Mean (LSMean) difference derived from the MMRM with 
the associated 95% confidence intervals (CI) and P-values. A Cohen’s D value will also be 
derived as the ratio of the estimated difference to the population standard deviation at each visit 
estimated from the model (the square root of the diagonal elements of the estimated covariance 
matrix). The missing values, including missing due to missed visits or early termination due to 
COVID-19 control measures, are assumed to be missing at random (MAR) in the main MMRM 
analysis. Sensitivity analyses will be performed to assess the impact of deviation from MAR 
assumptions on the analysis results. Time curve plots will be presented for both raw Mean 
(SEM) and LSMean (SE). 
5.9.3. 
Sensitivity Analyses 
5.9.3.1. 
Treatment Effect at Final Dose Levels 
To assess the treatment effect at the final dose level, a sensitivity analysis will be conducted on 
the mITT set using the MMRM analysis method described in Section 5.9.2 with treatment 
defined as the actual final dose level achieved. The final dose level is defined as the dose 
received at the Week 26 timepoint or at the time of early termination if the subject achieved a 
minimum of 5 mg prior to discontinuation. 
5.9.3.2. 
Treatment Effect based on Actual Treatment Received 
Should a discrepancy between the study treatment received and the randomized treatment 
assignment occurred in 6 or more subjects, a sensitivity analysis may be conducted based on the 
study treatments that subjects actually received using the MMRM analysis method described in 
Section 5.9.2. 
5.9.3.3. 
Remote Assessments Excluded (treated as missing) 
In addition, a sensitivity analysis excluding the MDS-UPDRS Part II + Part III combined score 
obtained remotely may be performed if such remote assessments are conducted due to 
COVID-19 restrictions. It should be noted that the study only has provision of remote 
assessments for Parts I & II of the MDS-UPDRS assessments, as the clinician administered 
motor examination required for Part III cannot be reliably completed remotely.

(National Research Council, 2010), it is unrealistic to expect no missing values in clinical trials. 
The impact of missing values on the analysis results will be assessed by the sensitivity analyses 
described below. 
Under Missing at Random (MAR) Assumption 
Multiple imputation (MI) will be performed to replace each missing value with a set of plausible 
values that represent the uncertainty about the correct value to impute. The Markov chain 
(MCMC) method will be utilized for the mITT set. SAS PROC MI will be used to generate 27 
possible imputed datasets: Each of these datasets will be analyzed using PROC MIXED in SAS 
using the MMRM model as described in Section 5.9.2. The results of the analyses of the datasets 
will be combined using PROC MIANALYZE to produce an inferential result. 
Considerations of Data Potentially Missing Not at Random (MNAR)  
A pattern mixture model (PMM) approach will be used to address potentially MNAR patterns. 
The following three patterns of subjects in the mITT set will be considered: 
1) 
Subjects with no missing values from discontinuation or from initiation of prohibited 
Parkinson’s disease concomitant mediation during treatment period. 
2) 
Subjects with missing values from the types of ICEs below will be considered having 
MNAR 
a. Subjects who discontinue due to reasons, as recorded on the eCRF, of lack of 
efficacy, adverse events associated with motor symptoms of Parkinson’s disease, 
physician decision, and withdrawal by subject. 
b. Subjects who initiated concomitant Parkinson’s disease medications (ATC 
classifications of ADAMANTANE DERIVATIVES, DOPAMINE AGONISTS, 
MONOAMINE OXIDASE B INHIBITORS, OTHER ANTIPARKINSON DRUGS, 
OTHER DOPAMINERGIC AGENTS, or DOPA AND DOPA DERIVATIVES) after 
the first dose of IMP and prior to the last dose of IMP with a use duration of 7 days or 
more will be considered having a potential confounding ICE. The efficacy data post 
ICE will be treated as missing with the missing pattern of MNAR.  
The MNAR cases will be identified and documented prior to database lock and unblinding 
(Section 9.5).  
3) 
Subjects with missing values from the type of ICEs below will be considered as having 
MAR 
a. Missing values after discontinuation due to reasons, as recorded on the eCRF, of 
death, pregnancy, loss to follow-up, adverse event unrelated to motor symptoms of 
Parkinson’s disease, non-compliance, site termination, protocol deviation, failure to 
meet continuation criteria and other will be considered as MAR.

The MNAR pattern 2) above in the active treatment group will be imputed using the jump to 
reference (J2R) method (Cro et. al. 2020) by assuming that patients jump to behave like those in 
the placebo group following their last observed time point. However, such MNAR in the placebo 
group will still be imputed as MAR using the standard multiple imputation method. 
The MAR patterns 3) will be imputed using the standard multiple imputation method described 
above.  
Other missing values due to missed visits/assessments before endpoint or discontinuation will 
also be assumed as MAR and imputed using the standard multiple imputation method for all 
three patterns. 
Core codes for MAR and MNAR imputations are provided in Section 9.6. 
Under Missing Completely at Random (MCAR) Assumption 
An additional sensitivity analysis will be conducted on the Endpoint (Week 26) Completer set 
using the MMRM analysis method described in Section 5.9.2. 
5.9.4. 
Subgroup Analyses 
Subgroup analyses of the primary endpoint will be made based on the mITT set to assess 
consistency of the intervention effect across the following subgroups:  
• Age group: < 65 vs ≥ 65 years 
• Sex: female vs male 
• Hoehn and Yahr Status at screening: 1 vs 1.5 vs 2 
• Baseline MDS-UPDRS Part II score: ≤ baseline median vs > baseline median 
(median of the mITT set regardless of treatment group) 
• Baseline MDS-UPDRS Part III score: ≤ baseline median vs > baseline median 
(median of the mITT set regardless of treatment group) 
• Use of concomitant MAO-B inhibitor: yes vs no 
• Years since initial diagnosis:(<1 year vs 1 to < 2 years vs 2 to < 3 years 
• Race: white vs other 
• Region: United States vs Non-US 
If the number of subjects within a subgroup is too small (less than 10% of the mITT set), the 
subgroup categories may be redefined prior to unblinding the study or the specific subgroup 
analysis may not be performed. Provided that the sample sizes in the subgroups allow, the 
MMRM analysis method described in Section 5.9.2 will be applied to the subgroup analysis 
(excluding the covariate of MAO-B inhibitor use in the MAO-B subgroup models). The 
treatment effect across subgroups will be summarized by forest plots.

Key Secondary Efficacy Analyses 
5.10.1. 
Secondary Estimand 1 
The key research question for the first secondary efficacy variable will be addressed with an 
estimand based on the following attributes:  
1) 
Treatments: treatments as randomized regardless of the actual treatment received or the 
final dose level achieved following the titration steps. 
2) 
Target study population of interest: subjects in the modified intent-to-treat (mITT) 
population regardless the completion status of dose titration steps. 
3) 
Endpoint (variable) of interest: change from baseline to Week 26 in the MDS-UPDRS 
Part II Score. 
4) 
Population level summary of interest: estimated mean difference between each tavapadon 
(CVL-751) dose group and placebo group in the endpoint of interest. 
5) 
Strategy for Intercurrent events (ICEs): a hypothetical strategy will be used to address 
intercurrent events (ICEs) of potential death, treatment discontinuations, missed 
visits/assessments, and start of prohibited concomitant Parkinson’s disease medications 
(see definitions in Section 5.9.1). The data after treatment discontinuations or after the 
start of prohibited concomitant Parkinson’s disease treatments will be censored under the 
hypothetical strategy. 
5.10.1.1. Main Analytical Approach 
Similar to the analysis of the primary efficacy variable, the change from baseline to each study 
visit in MDS-UPDRS Part II score will be summarized by visit and treatment group. A mixed 
model repeated measures (MMRM) analysis will be used with fixed effect of treatment group, 
visits, and interaction between treatment group and visit, and MAO-B inhibitor use. The baseline 
value of MDS-UPDRS Part II score will be included as a covariate. Subject will be included as a 
random effect. An unstructured covariance structure will be used for the repeated measures. If 
the unstructured covariance matrix results in convergence issue, the heterogeneous Toeplitz 
covariance structure followed by the heterogeneous first-order autoregressive (AR(1)) structure 
will be used. The Kenward-Roger approximation will be used to estimate the denominator 
degrees of freedom. The difference between each active dose and placebo at the endpoint visit 
(Week 26) will be estimated based on the Least Squares Mean (LSMean) difference derived 
from the MMRM with the associated 95% confidence intervals (CI) and P-values. A Cohen’s D 
value will also be derived as the ratio of the estimated difference to the population standard 
deviation at each visit estimated from the model (the square root of the diagonal elements of the 
estimated covariance matrix). The missing values, including missing due to missed visits or early 
termination due to COVID-19 control measures, are assumed to be missing at random (MAR) in 
the main MMRM analysis. Sensitivity analyses will be performed to assess the impact of 
deviation from MAR assumptions on the analysis results. Time curve plots will be presented for 
both raw Mean (SEM) and LSMean (SE).

5.10.1.2. Sensitivity Analyses 
The sensitivity analyses described in Section 5.9.3 for the primary estimand will also be 
performed for the secondary efficacy estimand 1. 
5.10.1.3. Subgroup Analyses 
The subgroup analyses described in Section 5.9.4 for the primary estimand will also be 
performed for the secondary efficacy estimand 1. 
5.10.2. 
Secondary Estimand 2 
The key research question for the second secondary efficacy variable will be addressed with an 
estimand based on the following attributes:  
1) 
Treatments: treatments as randomized regardless of the actual treatment received or the 
final dose level achieved following the titration steps. 
2) 
Target study population of interest: subjects in the modified intent-to-treat (mITT) 
population regardless the completion status of dose titration steps. 
3) 
Endpoint (variable) of interest: proportion of responders, defined as subjects with a score 
of “much improved” or “very much improved” on the PGIC, at Week 26. 
4) 
Population level summary of interest: : estimated difference expressed as odds ratio 
between each tavapadon (CVL-751) dose group and placebo group in achieving response. 
5) 
Strategy for Intercurrent events (ICEs): a hypothetical strategy will be used to address 
intercurrent events (ICEs) of potential death, treatment discontinuations, missed 
visits/assessments, and start of prohibited concomitant Parkinson’s disease medications 
(see definitions in Section 5.9.1). The data after treatment discontinuations or after the 
start of prohibited concomitant Parkinson’s disease treatments will be censored under the 
hypothetical strategy. 
5.10.2.1. Main Analytical Approach 
The number and percentage of responders will be summarized by visit and treatment group. The 
binomial repeated measures up to Week 27 will be analyzed using a generalized linear mixed 
model with logit link (SAS® GLIMMIX procedure). The treatment group, MAO-B inhibitor use, 
visits, and interaction between treatment group and visit will be included as fixed effect. An 
unstructured covariance structure will be used for the repeated measures. If the model does not 
converge with the unstructured covariance structure, the heterogeneous Toeplitz structure will be 
used. The odds ratio of each active dose to placebo at the endpoint visit will be estimated based 
on the Least Squares Mean difference in logit between the treatment groups from the GLIMMIX 
model with the associated 95% confidence intervals (CI) and P-values. The missing values are 
assumed to be missing at random, including missing due to missed visits or early termination due 
to COVID-19 control measures. Sensitivity analyses will be performed to assess the impact of 
deviation from MAR assumptions on the analysis results.

5.10.2.2. Sensitivity Analyses 
The sensitivity analyses described in Section 5.9.3 for the primary estimand will also be 
performed for the secondary efficacy estimand 2 except for the sensitivity analyses to assess the 
impact of missing value handling. For the secondary efficacy estimand 2, the case of potential 
MNAR will be imputed as “non-responder” for the sensitivity analysis. No additional sensitivity 
analysis under the MAR assumption using multiple imputations will be performed. In addition, a 
sensitivity analysis excluding the PGIC score obtained remotely may be performed if such 
remote assessments are conducted due to COVID-19 restrictions. 
5.10.2.3. Subgroup Analyses 
The subgroup analyses described in Section 5.9.4 for the primary estimand will also be 
performed for the secondary efficacy estimand 2: proportion of responders at Week 26.

assessment of relation to IMP will be assigned to the preferred term for the appropriate 
summaries. Events with missing severity or relationship will be classified as outlined in 
Section 3.2. Missing onset dates will be imputed as previously outlined in Section 4.1 as required 
to determine treatment-emergent events.

Summaries of treatment-emergent AEs will include any AEs reported beginning with the 
initiation of study drug on Day 1 through end of reporting period specified in the protocol post 
the last dose of IMP. The occurrence of TEAEs will be summarized by treatment group using 
preferred terms, system organ classes, and severity. The TEAEs by subgroup of MAO-B 
inhibitor use will be summarized by treatment, organ class, and preferred term. Separate 
summaries of treatment-emergent serious adverse events (TESAEs), TEAEs related to IMP, 
AESIs (including AEs related to abuse potential and AEs involving medication handling 
irregularities), events leading to the discontinuation of IMP, and AESIs that did not result in 
discontinuation of IMP or study will be generated respectively. A summary of AEs by treatment 
phase and by dose at event onset will also be presented. Adverse events leading to the 
discontinuation of IMP by preferred term and phase at onset will be prepared. All adverse events 
reported will be listed for individual subjects showing both verbatim and preferred terms. All 
adverse events that occurred prior to the initiation of study treatment or after the protocol-
specified reporting period post the last dose of IMP will be excluded from the summary tables 
but will be included in the listings.  
In addition, TEAEs rate per 100 person-years of exposure (PYE) will be summarized by 
treatment group using system organ class and preferred term. TEAEs with ≥2% incidence in 
either tavapadon dose group and a greater incidence than the placebo group will be summarized 
by treatment group using preferred term in descending order of the incidence in the tavapadon15 
mg group followed by that in the tavapadon 5 mg group. The most common TEAEs, defined as 
an incidence ≥5% in either tavapadon dose group and greater than 2 times of the incidence in the 
placebo group, will also be summarized by treatment group using preferred term in descending 
order of the incidence in the tavapadon15 mg group followed by that in the tavapadon 5 mg 
group. 
5.14.2. 
Epworth Sleepiness Scale (ESS) 
The ESS individual questions and total score and corresponding changes from baseline will be 
summarized by treatment group and study visit. The percentage of subjects with sleepy (10 or 
more) and very sleepy (18 or more) scores will also be summarized. ESS individual question 
score as well as the total score will be presented in a listing. The ESS total score will also be 
analyzed using the same method (MMRM analysis) describer in Section 5.9.2 to explore any 
treatment difference in sleepiness. Time curve plot will be presented for LSMean (SE) of change 
from baseline. 
5.14.3. 
Questionnaire for Impulsive-Compulsive Disorders in Parkinson Disease Rating 
Scale (QUIP-RS) 
The QUIP-RS component scores (Gambling, Sex, Buying, Eating, Hobbyism-Punding, PD 
Medication Use), total ICD score, and total score and corresponding changes from baseline will 
be summarized by treatment group and study visit. QUIP-RS individual data will be presented in 
a listing. The total ICD score will also be analyzed using the same method (MMRM analysis) 
describer in Section 5.9.2 to explore any treatment difference in impulsive-compulsive 
behaviors. Time curve plots will be presented for LSMean (SE) of change from baseline.

Non-IMP Medications and Non-Drug Therapy/Procedures 
The use of non-IMP medications will be coded using the World Health Organization (WHO) 
drug dictionary (WHODrug) (Version: Global B3 September 2019 or later). Concomitant 
medications, with start date on or after the date of the first IMP through the last IMP dose date, 
will be summarized by treatment group, frequency of drug classification, and generic drug name. 
Medications with start date after the last dose of IMP through the end of protocol-defined 
reporting period, will also be summarized. Prior medications use will be similarly summarized. 
All prior, concomitant, and post IMP medications will be presented in a data listing.  
The use of non-drug therapy/procedures will be coded using MedDRA Version 27.0 or higher. 
Concomitant and post-IMP non-drug therapy/procedures will be summarized by treatment group, 
frequency of system organ class and preferred term. All non-drug therapy/procedures will be 
presented in a data listing. 
5.14.5. 
Clinical Laboratory Assessments 
Descriptive summaries of selected (quantitative) clinical laboratory results will be presented by 
treatment group and study visit. Laboratory values outside the normal range for each 
systematically collected hematology, blood chemistry, and urinalysis parameter will be 
identified. Each subject’s hematology, blood chemistry, and quantitative urinalysis values will be 
flagged as “low” (below the lower limit of normal/LLN), “normal” (within the normal range), or 
“high” (above the upper limit of normal/ULN) relative to the normal ranges of the central 
laboratory. Each subject’s qualitative urinalysis results will be flagged as “normal” or 
“abnormal”. In addition, the severity of laboratory abnormality will be graded based on toxicity 
criteria specified in Section 9.8 in reference to Common Terminology Criteria for Adverse 
Events (CTCAE) Version 5.0. The result of each laboratory test for individual subjects will be 
presented in a listing with the normal range defined by the central laboratory, the status relative 
to the normal range, and the toxicity grade. 
Shift table will be used to summarize shifts from baseline toxicity grades to greatest (worst) 
treatment-emergent laboratory toxicity grade. For hematology and, blood chemistry, and 
quantitative urinalysis parameters that toxicity grade was not defined, a shift table for each 
laboratory test will be based on the shift from baseline high/normal/low status to the status of the 
maximum post-baseline value and the minimum post-baseline value (including test results from 
unscheduled visits, if any). Similarly, for qualitative urinalysis parameters, shifts from baseline 
normal/abnormal status to the worst post-baseline status will be summarized. 
The number and percentage of subjects who have post-baseline elevations in liver transaminase 
(alanine aminotransferase [ALT] or aspartate aminotransferase [AST]) or bilirubin abnormalities 
in relation to fold above the upper limit of normal will be summarized according to the Food and 
Drug Administration's Premarketing Clinical Evaluation on Drug-Induced Liver Injury Guidance 
for Industry (FDA 2009). Abnormal hepatic laboratory values will be categorized and evaluated 
for any occurrence among all post-baseline assessments (where “and” in the bulleted list below 
indicates elevations occurring at the same visit). Within each laboratory parameter grouping, a 
subject may be counted once per elevation criteria using the worst-case result.

That is, a subject with a worst case ALT elevation > 5 × the ULN would be counted once in the 
ALT > 3 × ULN category and once in the ALT > 5 × ULN category, regardless of how many 
ALT elevations the subject had that met the > 3 × ULN and > 5 × ULN elevation criteria. 
• ALT and/or AST > 3 × ULN and total bilirubin > 1.5 or 2 × ULN 
• AST > 3, 5, 10, 20 × ULN 
• ALT > 3, 5, 10, 20 × ULN  
• Total bilirubin > 1.5, 2 × ULN  
• Alkaline phosphatase (ALP) > 1.5 × ULN 
In addition, an eDISH plot, a shift plot showing liver safety panel tests over time (baseline vs. 
post-baseline), and distribution plots of ALT, AST, ALP, and bilirubin over time will be 
produced to aid identification of any potential cases (Merz M. et. al. 2014). The plots to be 
included are the scatter plot of maximum transaminase versus maximum bilirubin, the liver test 
safety panel over time, and the distribution of ALT by time. The distribution plots for AST, ALP, 
and bilirubin will use the same format as used for ALT. 
5.14.6. 
Vital Signs 
Vital signs include systolic and diastolic blood pressures, heart rate, and body temperature. 
Supine (after 5 minutes of rest) and standing (2 minutes after rising from supine to standing) 
measurements will be obtained for blood pressure and heart rate. Duplicate readings of supine 
blood pressure and heart rate will be taken. The duplicate values will be individually recorded, 
and the values will be averaged by the sponsor for the time point assessment. Orthostatic changes 
will be derived using standing and supine values. Body temperature will be obtained once, at the 
time of the first blood pressure measurement.  
5.14.6.1. Blood Pressure and Heart Rate 
Blood pressure and heart rate measurements and corresponding changes from baseline will be 
summarized by treatment group, position (if applicable), and visit using descriptive statistics. 
The distribution of diastolic and systolic blood pressure over time will be evaluated using box 
plots. Average records will be used for the analysis where available. 
Number and percent of subjects with at least one of the out-of-range value in blood pressure and 
heart rate will be summarized by treatment group based on the following criteria: 
Supine Systolic Blood Pressure (mmHg) 
• < 80 mmHg 
• < 90 mmHg 
• > 140 mmHg 
• > 160 mmHg 
• > 200 mmHg

• > 10 mmHg 
• > 20 mmHg 
Orthostatic Systolic Blood Pressure (mmHg) 
• ≥ 20 mmHg decrease upon standing compared with supine position 
• ≥ 20 mmHg increase upon standing compared with supine position 
Supine Diastolic Blood Pressure (mmHg) 
• < 50 mmHg

The number and percentage of the out-of-range values will also be summarized by treatment 
phase (titration and maintenance phase). For supine measurements, the average of the duplicate 
will be used to determined out-of-range status, unless in isolated cases where only a single 
measurement was taken.

5.14.6.2. Body Weight 
Body weight measurements at baseline and at the end of treatment with corresponding changes 
from baseline will be summarized by treatment group using descriptive statistics. 
Number and percent of subjects with out-of-range body weight changes will be summarized 
based on the following criteria: 
• Decrease from Baseline 7% or more (i.e. change from baseline ≤ -7%) 
• Increase from baseline 7% or more (i.e. change from baseline ≥7%) 
5.14.6.3. Temperature 
Temperature and corresponding changes from baseline will be summarized by treatment group, 
and visit using descriptive statistics. Number and percent of subjects with out-of-range 
temperature will be summarized based on the following criteria: 
• >38.0 °C 
• <36.0 °C 
5.14.7. 
Electrocardiograms (ECGs) 
Single or triplicate 12 lead ECGs will be obtained during the trial. All ECG recordings will be 
obtained after the subject has been supine and at rest for at least 5 minutes. A triplicate set of 
ECGs is 3 consecutive ECGs collected 1 to 2 minutes apart over a 5 minute period. Any values 
taken in triplicate will be averaged for analysis. ECGs and corresponding changes from baseline 
will be summarized by treatment group and visit using descriptive statistics. Average records 
will be used for the analysis where available. 
The number and percentage of subjects who experience any post-baseline occurrence of 
potentially clinically significant corrected QT values using Fridericia's method (QTcF) will be 
summarized by treatment group. These presentations will include QTcF values > 450 to ≤ 480, 
> 480 to ≤ 500, and > 500 msec; or changes of > 30 to ≤ 60 or > 60 msec (FDA, 2005). For this 
categorization, the average of triplicate values will be utilized rather than the individual values 
comprising the triplicate measurement. An out-of-range categorical tabulation will also be 
presented for the subgroup of U.S subjects.  
Additionally, a distribution plot of QTcF over time will be presented as an aid in identification of 
any possible time trend and outliers. 
A substudy to evaluate the effect of tavapadon on the QT interval using C-QT modelling is also 
included in this trial. Matched triplicate ECGs and plasma tavapadon concentrations that are 
collected at preselected sites will be used to characterize the effects of tavapadon on the QT 
interval. The analysis plan is summarized separately. 
5.14.8. 
Physical and Neurological Examinations 
Physical and Neurological examination data will be listed.

Columbia-Suicide Severity Rating Scale (C-SSRS) 
The maximum post-baseline results from the C-SSRS will be summarized. The maximum of 
each subscale (suicidal ideation [Categories 1-5], suicidal behavior [Categories 6-10], suicidal 
ideation or behavior [Categories 1-10], and self-injurious behavior without suicidal intent) will 
be presented. The number of patients with suicide-related treatment-emergent events, 
treatment-emergent suicidal ideation, and suicidal behavior, based on a comparison of the 
C-SSRS at baseline and/or previous lifetime experience to maximum C-SSRS scores across all 
post-baseline assessments will be provided. All C-SSRS elements will be reflected in a listing. 
5.15. 
Pharmacokinetics 
Plasma concentrations of tavapadon and CV-0000053 (metabolite) will be determined using a 
validated LC-MS/MS method. PK data listings will be presented for the PK population. PK 
summary tables and mean figures will be presented using the PK analysis set. 
5.15.1. 
Pharmacokinetic Data Analysis 
Plasma concentrations of tavapadon and CV-0000053 (metabolite) will be summarized 
separately using descriptive statistics by visit. Plasma concentrations of tavapadon and 
CV-0000053 that are <LLOQ will be reported as ‘BLQ’ in the data listings. Plasma 
concentrations that are BLQ will be treated as 0 for calculation of descriptive statistics. The 
geometric mean, however, will be calculated by imputing BLQ values as ½ LLOQ. If the 
calculated mean concentration is below the limit of quantitation, the mean will be reported as 
BLQ and the SD and CV% shall be reported as not determined (ND). Mean plasma 
concentrations (SD) of tavapadon and CV-0000053 will also be plotted versus time (in both 
linear and semi-logarithmic scale) based on nominal visit.  
5.16. 
Protocol Deviations 
All protocol deviations will be reviewed by the project team prior to database lock and 
unblinding to identify subjects with important protocol deviations. The number and percentage 
of subjects with important deviations will be tabulated by treatment and further tabulated by 
category and treatment. All deviations from the protocol will be listed by category along with a 
description and any additional comments.

a. 
Subjects who prematurely discontinue from the trial or who are not eligible for or choose not to participate in the open-label extension trial (Protocol CVL-751-PD-004) are to 
participate in the 4-week Safety Follow-Up Period. Subjects who proceed into the open-label extension trial will go directly into that trial and will not complete the Safety 
Follow-Up Period. 
b. 
The assessments scheduled for the Week 27 visit are to be performed for any subject who prematurely discontinues from the trial. 
c. 
Contact with subjects via telephone call or other means of communication to check on their status. 
d. 
Informed consent must be obtained before any trial-related procedures are performed. 
e. 
Medical occurrences that begin before the start of IMP dosing but after obtaining informed consent will be recorded as medical and/or psychiatric history. 
f. 
MDS-UPDRS Parts I, II, and III will be conducted before the first dose of IMP at the Baseline Visit and at ~2 to ~6 hours after dosing (at home) at clinic visits during the 
Treatment Period. 
g. 
All responses will be relative to the subject’s condition at the Baseline Visit (Day 1) before the first dose of IMP. 
h. 
The “Baseline/Screening” C-SSRS form will be completed at the Screening Visit to determine eligibility. The “Since Last Visit” C-SSRS form will be completed at the 
Baseline Visit to ensure that the subject continues to qualify for the trial and at all visits after the Baseline Visit. 
i. 
Full physical and neurological examinations should be completed at the Screening Visit and at Week 27. The physical examination should include height at the Screening 
Visit only. Physical and/or neurological examinations can be done at any time point during the trial at the investigator's discretion.

j. 
Duplicate measurements of blood pressure and heart rate will be obtained in supine (after 5 minutes of rest) and 1 measurement of blood pressure and heart rate will be 
obtained on standing (2 minutes after rising from supine to standing). 
k. 
A triplicate set of ECGs is 3 consecutive ECGs collected 1 to 2 minutes apart over a 5-minute period. 
l. 
The postdose ECGs (triplicate set for US sites at all visits and single for non-US sites at all visits) will be obtained at ~1 hour after administration of the first dose of IMP at 
the Baseline Visit just prior to the time of collection of the PK blood sample. ECGs at all postbaseline visits will be obtained just prior to the time of collection of the PK 
blood sample. 
m. All adverse events that are observed by trial personnel or volunteered by the subject in response to open-ended questioning will be recorded from the first dose of IMP through 
the end of the Safety Follow-up Period. Serious adverse events will be followed until resolution. 
n. 
Individual sites may require subjects to have COVID-19 testing done prior to randomization. COVID-19 testing may be performed after randomization per the principal 
investigator’s discretion. 
o. 
Dipstick urinalysis results are not to be recorded on the eCRFs; any clinically significant abnormality should be captured as an adverse event. 
p. 
For women of childbearing potential only. All positive urine dipstick pregnancy tests must be confirmed by a serum test. Pregnancy tests can be performed at any time during 
the trial at the discretion of the investigator. Female subjects with exclusively the same sex partners may not be required to have pregnancy tests per investigator discretion; 
confirmation with the medical monitor is required. 
q. 
A urine drug screen is required at screening (see exclusion criteria for exclusions based on the urine drug screen) and may be obtained at other times, at investigator discretion, 
if use of prohibited drugs is suspected. 
r. 
PK samples will be collected ~1 hour after administration of the first dose (Day 1) and at the clinic visits at the end of Weeks 5, 11, 14, 22, and 27 just after ECG acquisition 
at each time point. The date and time of the most recent dose, the dose amount, and the time of the blood draw will be recorded.  
s. 
Future biospecimen research sample is optional and is to only be collected if signed consent is obtained from the subject. 
t. 
The first dose of IMP (at the Baseline Visit) will be taken in the clinic; all other doses will be taken on an outpatient basis. Subjects will be instructed to bring their IMP to 
each clinic visit. Compliance will be assessed through self-reporting by the subject and by tablet count. 
u. 
Prolactin results will be blinded.

9.3. 
Columbia-Suicide Severity Rating Scale (C-SSRS) Suicidal Ideation 
and Suicidal Behavior Scores 
The C-SSRS is comprised of 10 categories with binary responses. The 10 categories include: 
Category 1 – Wish to be Dead  
Category 2 – Non-specific Active Suicidal Thoughts  
Category 3 – Active Suicidal Ideation with Any Methods (Not Plan) without Intent to Act  
Category 4 – Active Suicidal Ideation with Some Intent to Act, without Specific Plan  
Category 5 – Active Suicidal Ideation with Specific Plan and Intent  
Category 6 – Preparatory Acts or Behavior  
Category 7 – Aborted Attempt  
Category 8 – Interrupted Attempt  
Category 9 – Actual Attempt (non-fatal)  
Category 10 – Completed Suicide 
Categories 1-5 represent Suicidal Ideation and categories 6-10 represent Suicidal Behavior. Each 
category is scored as 1 if there is a positive response in the category and a 0 if there are no 
positive responses in the category.   
• Self-Injurious Behavior Without Suicidal Intent During Treatment 
A subject will be categorized as having self-injurious behavior without suicidal intent if there is 
an occurrence of non-suicidal self-injurious behavior on the C-SSRS – Since Last Visit eCRF at 
any post-baseline visit. 
• Baseline C-SSRS Score  
Baseline represents the pre-treatment assessment of recent history, with elements of suicidal 
ideation assessed over the prior 6 months and elements of suicidal behavior assessed over the 
prior 2 years. It is scaled from 0 (no suicidal ideation or behavior) to 10 (completed suicide) 
• Treatment-Emergent Suicide-Related Event  
A subject will be categorized as having a treatment-emergent suicide-related event if at least one 
post-baseline suicidal ideation or suicidal behavior score is greater than 0.  
• Treatment-Emergent Suicidal Ideation Compared to Recent History 
A subject will be categorized as having treatment-emergent suicidal ideation compared to recent 
history when there is at least one post-baseline suicidal ideation score > 0 and is an increase from 
baseline. Lifetime scores are not considered for baseline suicidal ideation responses. 
• Treatment-Emergent Serious Suicidal Ideation Compared to Recent History 
A subject will be categorized as having treatment-emergent serious suicidal ideation compared to 
recent history if the baseline score was < 4 and the post-baseline suicidal ideation score increases 
to 4 or 5. Lifetime scores are not considered for baseline suicidal ideation responses.

• Emergence of Serious Suicidal Ideation Compared to Recent History 
A subject will be categorized as having emergence of serious suicidal ideation compared to 
recent history if baseline score was 0 (no suicidal ideation) and post-baseline C-SSRS suicidal 
ideation score is either 4 or 5. Lifetime scores are not considered for baseline suicidal ideation 
responses.  
• Emergence of Suicidal Behavior Compared to all Prior History 
A subject will be categorized as having emergence of suicidal behavior compared to all prior 
history if there had been no suicidal behavior in Categories 6-10 reported at any pre-treatment 
assessment, including responses to lifetime history questions, and there is at least one positive 
post-baseline C-SSRS assessment in Categories 6-10. ‘All Prior History’ represents lifetime 
history.

9.4. 
Programming Conventions 
• Page orientation, margins, and fonts: Summary tables, listings, and figures will appear in 
landscape orientation. There should be a 1.0” boundary on the left and right edges. The 
top and bottom margins are 1.0” for tables and listings, but may vary for figures. Output 
should be printed in Courier New with a point size of 8.  
• Identification of analysis population: Every summary table, listing, and figure will clearly 
specify the analysis population being summarized/listed. Listings will be prepared for all 
subjects randomized. 
• Group headers: In the summary tables, the group headers will identify the within-group 
sample size for the indicated analysis population. Of note, the header’s sample size does 
not necessarily equal the number of subjects actually summarized within any given 
summary module; some subjects in the analysis population may have missing values and 
thus may not be summarized. 
• Suppression of percentages corresponding to null categories: When count data are 
presented as category frequencies and corresponding percentages, the percent should be 
suppressed when the count is zero in order to draw attention to the non-zero counts. 
• Presentation of sample sizes: Summary modules should indicate, in one way or another, 
the number of subjects actually contributing to the summary statistics presented in any 
given summary module. As mentioned above, this may be less than the number of 
subjects in the analysis population. 
 In the quantitative modules describing continuous variables (and thus presenting 
sample size, means, and standard deviations), the sample size should be the 
number of non-missing observations 
 For categorical variables that are presented in frequency tables, the module should 
present the total count in addition to the count in each category. Percentages 
should be calculated using this total as the denominator, and the percentage 
corresponding to the sum itself (that is, 100%) should be presented so as to 
indicate clearly to a reviewer the method of calculation. 
• Sorting: Listings will be sorted by treatment, subject number and date, if applicable. If a 
listing is sorted in a different manner, it will be indicated on the listing shells.  
• General formatting rules: Rounding for all variables will occur only as the last step, 
immediately prior to presentation in listings, tables, and figures. No intermediate 
rounding will be performed on derived variables. The standard rounding practice of 
rounding numbers ending in 0-4 down and numbers ending in 5-9 up will be employed.  
• The presentation of numerical values will adhere to the following guidelines (exceptions 
may be necessary in some circumstances for derived analysis variables to allow readability):  
 Raw measurements will be reported to the number of significant digits as captured 
electronically or on the eCRFs.

 Standard deviations will be reported to two decimal places beyond the number of 
decimal places the original parameter is presented. EQ-5D-5L Index Score 
summaries will use 4 decimal places for standard deviation. 
 Means medians, and quartiles will be reported to one decimal place beyond the 
number of decimal places the original parameter is presented.  
 will be reported to the one decimal place beyond the number of decimal places the 
original parameter is presented. 
 Calculated percentages will be reported with one decimal place.  
 Coefficient of variation will be reported to the same number of decimal places as 
the standard deviation.  
 P-values will be reported to 4 decimal places 
• Dates will be formatted as DDMMMYYYY. Partial dates will be presented on data 
listings as recorded on eCRFs. 
• Time will be presented according to the 24-hour clock (HH:MM). 
• Verification of Results: All analyses will be subject to formal verification procedures. 
Specifically, results will be verified utilizing independent programming prior to issuance 
of the draft statistical report. All documents will be verified by the lead statistician to 
ensure accuracy and consistency of analyses.

Core Codes for imputation of MAR and MNAR 
9.6.1. 
Imputation of Missing at Random (MAR) Cases 
SAS PROC MI will be used to generate 27 possible imputed datasets using the following SAS 
code: 
proc mi data=mcmc1 seed=SEED1 nimpute=27 out=Out1X; 
mcmc chain=multiple displayinit initial=em(itprint); 
var TRT y0 y1 y2 … yn; 
run; 
Here, TRT is an indicator variable representing treatment with values of ‘CVL-751 5 mg’, CVL-
751 15 mg’, or ‘Placebo’, Y1 - YN represent the response variable (e.g., MDS-UPDRS Part II+III 
score) for each visit, Y0 is the baseline score, and SEED1 is a random number. 
Each of these datasets will be analyzed using PROC MIXED in SAS using the MMRM model. 
The results of the analyses of the datasets will be combined using PROC MIANALYZE to 
produce an inferential result. 
9.6.2. 
Imputation of Missing Not at Random (MNAR) Cases 
The MNAR cases are imputed using reference based imputation (J2R) method. The five macros; 
SAS code for reference based multiple imputation [https://www.lshtm.ac.uk/research/centres-
projects-groups/missing-data#dia-working-group] will be used to generate 27 possible imputed 
datasets using the following sample SAS code: 
%include "&Path\part1A_33.sas"; 
%include "&Path\part1B_47.sas"; 
%include "&Path\part2A 40.sas"; 
%include "&Path\part2B_31.sas"; 
%include "&Path\part3_55.sas"; 
%include "&Path\plotter_7.sas"; 
 
%part1A(Jobname=X,Data=XX,Subject=usubjid,Response=aval,Time=avisitn,Treat=Tr
t01pn, cov=BASE, Catcov=MAOBINHI, covgroup=trt01pn,Debug=1); 
%part1b(Jobname=X, Ndraws=27, thin=350, seed=s, Debug=1); 
 
%part2a(Jobname=X J2R, inname=XX, method=J2R,ref=0, Debug=1); 
%part2b(Jobname=X_J2R, seed=s, Debug=1); 
 
Each of these datasets will be analyzed using PROC MIXED in SAS using the MMRM model. 
The results of the analyses of the datasets will be combined using PROC MIANALYZE to 
produce an inferential result.
