Brief summary:
This is an open-label study designed to evaluate the safety, tolerability and efficacy of CAD-1883, a positive allosteric modulator of the SK channel, administered twice daily orally to adult patients with ET. Patients with the diagnosis of ET based on the Movement Disorder Society (MDS) criteria with a documented severity of tremor based on the clinician-administered TETRAS Performance Subscale are eligible to be enrolled in the study.

Detailed description:
This is an open-label study designed to evaluate the safety, tolerability and efficacy of CAD-1883, a positive allosteric modulator (PAM) of the SK channel, administered twice daily orally to adult subjects with ET. Positive modulation of the small-conductance calcium-activated potassium channels (SK) present in different regions of the brain aims to increase the channel sensitivity to calcium resulting in reduction in neuronal firing rate. In patients with ET, improving the regularity of firing of action potentials in the olivo-cerebellar network can lead to improvement in motor function.

During the Screening period, each subject will undergo full assessment including medical and treatment history for ET, physical examination and other screening assessments. Patients with the diagnosis of ET based on the Movement Disorder Society (MDS) criteria with a documented severity of tremor based on the clinician-administered TETRAS Performance Subscale are eligible to be enrolled in the study. The study consists of treatment groups receiving twice daily oral dosing of CAD-1883 for a treatment period of 14 days.

This study is designed to enable the assessment of safety and tolerability of CAD-1883 in patients with ET as well as the determination of early treatment effect on reducing the magnitude and severity of tremor while limiting the potential risk associated with a novel investigational drug.

Safety and tolerability will be monitored throughout the study duration including in-clinic assessments of adverse events (AEs), serious adverse events (SAEs), vital signs, 12-lead ECG, urinalysis, hematology, clinical chemistry, and CAD-1883 plasma concentration level on Days 1, 7, 14 and 21.

Efficacy will be evaluated using the clinician-administered TETRAS Performance Subscale as well as the use of a wearable sensor in the clinic and at home.

Protocol Title 
A Phase 2a Open-Label Study to Evaluate the Safety, Tolerability and 
Efficacy of CAD-1883 Oral Treatment in Adults with Essential Tremor 
(CADENCE-1) 
Study Phase 
2a 
Study Rationale 
CAD-1883 is an investigational product being developed as a new treatment 
for Essential Tremor (ET), a movement disorder characterized by dysfunction 
of the cerebellum and its associated motor control circuit (Haubenberger 
et al, 2018). Tremor is defined as a rhythmic and oscillatory movement of a 
body part with a relatively constant frequency and variable amplitude. It is 
caused by alternating contractions of antagonistic muscles. Tremor is the 
most common of all movement disorders, and ET is the most common 
neurologic cause of tremor. The usual course of ET is one of gradual 
progression. Patients with persistent disability from ET need continuous 
symptomatic drug therapy. Available drug treatments are not effective in all 
patients, often provide inadequate symptomatic relief, and the symptomatic 
benefit of chronic administration often declines over time and is frequently 
associated with intolerable side effects. Therapy options for ET patients who 
do not benefit from pharmacologic treatment include deep brain stimulation 
(DBS) requiring surgery for placement of brain stimulator(s), magnetic 
resonance image (MRI)-guided thalamotomy via focused ultrasound (to treat 
persistently disabling unilateral limb tremor), or botulinum toxin injections 
(to treat persistently disabling hand, head, or vocal cord tremor). The efficacy 
of these invasive, non-pharmacologic therapies may also wane over time, and 
may be associated with intolerable side effects. Therefore, to address these 
important unmet medical needs, efforts are required to develop new 
treatments for ET targeting the cerebellar dysregulation responsible for the 
movement disorder. 
The cerebellum is required for coordinated motion, including movements of 
the hands, limbs, trunk, and eyes, and the synchrony of speech, all of which 
are disrupted in ET. The cerebellar cortex, together with the inferior olivary 
nucleus and deep cerebellar nuclei, comprises the olivocerebellar circuit. 
Cerebellar output critically depends on the precise timing of action potentials 
in the principal neurons of the olivocerebellar circuit, especially cerebellar 
Purkinje neurons (Llinas, 2014). 
Small conductance calcium-activated potassium (SK) channels are a family 
of potassium channels gated by intracellular calcium (Kshatri, 2018). In 
neurons, SK channels are gated by calcium that passes through voltage-gated 
calcium channels, which are activated by each action potential. SK channels

regulate action potential timing by generating hyperpolarizing potassium 
currents between action potentials. In principle neurons of the olivocerebellar 
circuit, including cerebellar Purkinje neurons and their major afferent 
neurons of the inferior olivary nucleus, SK2 and SK3 channel-mediated after-
hyperpolarizing currents represent a molecular pace-making mechanism 
centrally implicated in the coordination of movement. 
CAD-1883 is a small molecule positive allosteric modulator (PAM) of SK 
channels 
CAD-1883 represents the first selective SK channel PAM 
candidate suitable for entering clinical development in patients with ET. 
CAD-1883 is anticipated to be used for the treatment of ET throughout the 
course of the patient’s disease. This study offers the opportunity to 
understand the safety, tolerability, and efficacy of CAD-1883 in the ET 
patient population.

Study Design 
This is an open-label study designed to evaluate the safety, tolerability, and 
efficacy of CAD-1883 administered twice daily orally to adult subjects with 
ET. Subjects will undergo a screening period of a minimum of 14 days up to 
a maximum of 35 days in which the subject will washout from prior 
, to allow the effects of previous 
medication(s)
 to be eliminated. During the Screening period, each 
subject will undergo full assessment including medical and treatment history 
for ET, physical and neurological examination, in addition to laboratory 
testing, 12-lead electrocardiogram (ECG), and other screening assessments. 
The diagnosis of ET must be established by the Investigator at Screening 
based on the Movement Disorder Society (MDS) criteria (Bhatia, 2018) with 
a documented severity of tremor based on the clinician-administered 
TETRAS-PS (Elble, 2012). 
Per the Investigator’s discretion, re-testing of any laboratory abnormality at 
the central lab or at a local lab is permissible, with prior approval from the 
Medical Monitor. 
Subjects who previously failed screening can be invited to rescreen up to two 
additional times, with recommendation by the Investigator and with approval 
by the Sponsor. 
The study will be open label consisting of 1 treatment group receiving 
300 mg twice daily oral dosing of CAD-1883 for a treatment period of 
14 days. 
The selected dose is anticipated to be well-tolerated by subjects with ET for 
the duration of the treatment period. A 14-day treatment period represents an 
adequate time period to permit the initial assessment of safety and tolerability 
of CAD-1883 as well as a determination of early treatment effect on reducing 
the magnitude and severity of tremor while limiting the potential risk 
associated with a novel investigational drug. 
Safety and tolerability will be monitored throughout the study duration 
including in-clinic assessments of adverse events (AEs), serious adverse 
events (SAEs), vital signs including orthostatic vital signs, 12-lead ECG, 
urinalysis, hematology, clinical chemistry, composite biomarker panel for 
renal tubular injury, and CAD-1883 plasma concentration level on Days 1, 7, 
14, and 21. 
Efficacy will be evaluated as follows: 
•
TETRAS-PS total score change from Baseline to Day 14
•
TETRAS-PS upper limb subscale score change from Baseline to Day
14

•
Change from Baseline to Day 14 in upper limb tremor severity, mean
amplitude, and mean frequency, measured in the clinic using a wearable
sensor
• 
The TETRAS-PS will be recorded via videography for centralized evaluation 
and rating by an independent blinded panel of experts.  
At the Baseline/Pre-dose visit (which is the last day of the Screening period), 
subjects will undergo all required procedures including confirmation that all 
eligibility criteria are met. 
The Day 1 visit can occur up to 3 business days following the Baseline/Pre-
dose visit. Analysis of the pre-dose laboratory assessments (chemistry, 
hematology, urinalysis) should be conducted by the Central Laboratory, with 
the results available and reviewed by the Principal Investigator, or designee, 
prior to dosing the subject with CAD-1883 (Day 1 visit). On Day 1, subjects 
will be dosed in the clinic with the first dose of CAD-1883 300 mg 
(3 capsules of 100 mg each) and will be monitored in the clinic prior to 
ingesting the second dose of CAD-1883 300 mg (3 capsules of 100 mg each) 
in the clinic, 4 to 5 hours later.  Additional safety and all efficacy assessments 
will be completed after the 2nd in clinic dose on Day 1 as indicated in the 
SOA (Appendix A, Table 2). 
Subjects will be dispensed study drug for continued twice-daily oral self-
administration at home. After Day 1, subjects are instructed to ingest the first 
daily dose of CAD-1883 of 300 mg (3 capsules of 100 mg each) at home 
upon awakening in the morning. The second daily dose of 300 mg (3 
capsules of 100 mg each) will be taken 8 hours (±2 hours) after the first daily 
dose. Each subject is provided with a medication diary to denote the date and 
time of at-home study drug dosing. 
The pre-dose laboratory assessments (chemistry, hematology, urinalysis) 
should be sent to the Central Laboratory for analysis. Under exceptional 
circumstances, the pre-dose laboratory assessments (chemistry, hematology, 
urinalysis) can be sent for expedited analysis at the local laboratory, along 
with duplicate samples sent to the Central Laboratory. The results of all 
laboratory assessments should be available and reviewed by the Principal 
Investigator, or designee, prior to dosing the subject. 
Subjects will return to the site for further assessments on Day 7 (-1 day) and 
Day 14 (±1 day). On these two site visit days, the subjects are instructed to 
ingest the first daily dose of CAD-1883 of 300 mg (3 capsules of 100 mg 
each) 4 to 5 hours prior to the scheduled and/or anticipated dosing of the 
second daily dose of CAD-1883 in the clinic. The second daily dose of CAD-
1883 300 mg (3 capsules of 100 mg each) will be taken in the clinic, under 
the supervision of study staff, 4 to 5 hours after the first daily dose.

Efficacy Assessments: 
Rating Scales 
The treatment effect will be evaluated by means of the TETRAS-PS, which is 
a validated scale that has been used in recently conducted clinical trials in 
subjects with ET (Elble, 2012). It provides an accurate reflection of the 
clinical response to treatment on the amplitude of tremor over multiple bodily 
locations and over time. 
The TETRAS assessments at Screening, Baseline/Pre-dose, Days 1, 7, 14, 
and Follow-up visit (Day 21) will be administered by a certified rater. 
TETRAS raters at each site must demonstrate expertise in the administration 
of the TETRAS according to criteria preset by independent central rating 
experts. The TETRAS raters at each site can be the Principal Investigator or a 
staff member delegated as a rater by the Principal Investigator. Each site must 
make every effort, to the extent that is possible, to ensure availability of a 
primary rater and a backup rater to perform all TETRAS assessments on the 
same subjects throughout the study duration. 
The TETRAS-PS assessments at the Screening visit, Baseline/Pre-dose, Day 
1, Day 7, Day 14, and Day 21 clinic visits will be recorded using 
videography for centralized evaluation and rating by independent blinded 
central raters (neurologists) with expertise in the assessment of ET.

On Day 1: the TETRAS-PS will be administered 2 to 4 hours following the 
second in-clinic dose. 
On Day 7: the TETRAS-PS, 
will be performed 2 to 4 hours following the in-clinic dose. 
On Day 14: the TETRAS-PS, 
will be performed 2 to 4 hours following the in-clinic dose. 
At Follow up visit (Day 21): the TETRAS-PS,
are performed once any time during the visit. 
Efficacy Assessments: 
Wearable Sensor 
In addition to the assessment of efficacy via rating scales, treatment effect 
will be evaluated by measuring tremor with a sensor worn on the upper limb 
(index finger). These assessments will be conducted during the clinic visits 
and optionally at-home. 
In-Clinic Assessment: 
The wearable sensor measurements of upper limb tremor will be completed 
in the clinic once at any time during the Screening visit and at two different 
times during the Baseline/Pre-dose site visit. 
During the clinic visits on Day 1, the wearable sensor measurements of upper 
limb tremor will be captured once, 2 to 4 hours following the second in-clinic 
dose. 
During the site visits on Days 7 and 14, the wearable sensor measurements of 
upper limb tremor will be captured once, 2 to 4 hours following the in-clinic 
dose. 
During the Follow-up visit (Day 21), the wearable sensor measurements of 
upper limb tremor will be completed once, at any time during the visit.

INTRODUCTION AND BACKGROUND INFORMATION 
CAD-1883 is an investigational product being developed as a new treatment for Essential 
Tremor (ET), a movement disorder characterized by dysfunction of the cerebellum and its 
associated motor control circuit (Haubenberger et al, 2018). Tremor is defined as a rhythmic and 
oscillatory movement of a body part with a relatively constant frequency and variable amplitude. 
It is caused by alternating contractions of antagonistic muscles. Tremor is the most common of 
all movement disorders, and ET is the most common neurologic cause of tremor. The usual 
course of ET is one of gradual progression. Patients with persistent disability from ET need 
continuous symptomatic drug therapy. Available drug treatments are not effective in all patients, 
often provide inadequate symptomatic relief, and the symptomatic benefit of chronic 
administration often declines over time and is frequently associated with intolerable side effects. 
Therapy options for ET patients who do not benefit from pharmacologic treatment include deep 
brain stimulation (DBS) requiring surgery for placement of brain stimulator(s), magnetic 
resonance image (MRI)-guided thalamotomy via focused ultrasound (to treat persistently 
disabling unilateral limb tremor), or botulinum toxin injections (to treat persistently disabling 
hand, head, or vocal cord tremor). The efficacy of these invasive, non-pharmacologic therapies 
may also wane over time, and may be associated with intolerable side effects. Therefore, to 
address these important unmet medical needs, efforts are required to develop new treatments for 
ET targeting the cerebellar dysregulation responsible for the movement disorder. 
The cerebellum is required for coordinated motion, including movements of the hands, limbs, 
trunk, and eyes, and the synchrony of speech, all of which are disrupted in ET. The cerebellar 
cortex, together with the inferior olivary nucleus and deep cerebellar nuclei, comprises the 
olivocerebellar circuit. Cerebellar output critically depends on the precise timing of action 
potentials in the principal neurons of the olivocerebellar circuit, especially cerebellar Purkinje 
neurons (Llinas, 2014). 
Small conductance calcium-activated potassium (SK) channels are a family of potassium 
channels gated by intracellular calcium (Kshatri, 2018) In neurons, SK channels are gated by 
calcium that passes through voltage-gated calcium channels, which are activated by each action 
potential. SK channels regulate action potential timing by generating hyperpolarizing potassium 
currents between action potentials. In principle neurons of the olivocerebellar circuit, including 
cerebellar Purkinje neurons and their major afferent neurons of the inferior olivary nucleus, SK2 
and SK3 channel-mediated after-hyperpolarizing currents represent a molecular pace-making 
mechanism centrally implicated in the coordination of movement.

CAD-1883 is anticipated to be used for the treatment of ET throughout the course of the patient’s 
disease. This study offers the opportunity to understand the safety, tolerability, and efficacy of 
CAD-1883 in the ET patient population. 
1.1 
Rationale and Risk Benefit 
The study will be open-label consisting of 1 treatment group receiving twice-daily oral dosing of 
CAD-1883 for a treatment period of 14 days. 
The selected dose is anticipated to be well-tolerated by subjects with ET for the duration of the 
treatment period. A 14-day treatment period represents an adequate time period to permit the 
initial assessment of safety and tolerability of CAD-1883 as well as a determination of early 
treatment effect on reducing the magnitude and severity of tremor while limiting the potential 
risk associated with a novel investigational drug.

STUDY DESIGN 
3.1 
Summary of Study Design 
This is an open-label study designed to evaluate the safety, tolerability, and efficacy of CAD-1883 
administered twice daily orally to adult subjects with ET. 
Subjects will undergo a screening period of a minimum of 14 days up to a maximum 
of 35 days in which the subject will “wash-out” from prior tremorgenic and anti-tremor 
medications, to allow the effects of previous medication(s) on tremor to be eliminated. During 
the Screening period, each subject will undergo full assessment including medical and treatment 
history for ET, physical and neurological examination, in addition to laboratory testing, 12-lead 
electrocardiogram (ECG), and other screening assessments. The diagnosis of ET must be 
established by the Principal Investigator at Screening based on the Movement Disorder Society 
(MDS) criteria (Bhatia, 2018) with a documented severity of tremor based on the clinician-
administered TETRAS-PS (Elble, 2012).
Safety and tolerability will be monitored throughout the study duration including in-clinic 
assessments of adverse events (AEs), serious adverse events (SAEs), vital signs including 
orthostatic vital signs, 12-lead ECG, urinalysis, hematology, clinical chemistry, and CAD-1883 
plasma concentration level on Days 1, 7, 14, and 21. 
Efficacy will be evaluated as follows: 
•
TETRAS-PS total score change from Baseline to Day 14
•
TETRAS-PS upper limb subscale score change from Baseline to Day 14
•
Change from Baseline to Day 14 in upper limb tremor severity, mean amplitude, and
mean frequency, measured in the clinic using a wearable sensor
The TETRAS-PS will be recorded via videography for centralized evaluation and rating by an 
independent blinded panel of expert(s).  
At the Baseline/Pre-dose visit, subjects will undergo all required procedures including 
confirmation that all eligibility criteria are met. 
The Day 1 visit can occur up to 3 business days following the Baseline/Pre-dose visit. Analysis 
of the pre-dose laboratory assessments (chemistry, hematology, urinalysis) should be conducted 
by the Central Laboratory, with the results available and reviewed by the Principal Investigator, 
or designee, prior to dosing the subject with CAD-1883 (Day 1 visit). On Day 1, subjects will be 
dosed in the clinic with the first dose of CAD-1883 300 mg (3 capsules of 100 mg each) and will

be monitored in the clinic prior to ingesting the second dose of CAD-1883 300 mg (3 capsules of 
100 mg each), 4 to 5 hours later.  Additional safety and all efficacy assessments will be 
completed after the 2nd in clinic dose on Day 1 as specified in the SOA (Appendix A, Table 2). 
Subjects will be dispensed study drug for continued twice-daily oral self-administration at home. 
After Day 1, subjects are instructed to ingest the first daily dose of CAD-1883 of 300 mg (3 
capsules of 100 mg each). The second daily dose of CAD-1883 300 mg (3 capsules of 100 mg 
each) will be taken 8 hours (±2 hours) after the first daily dose. Each subject is provided with a 
medication diary to denote the date and time of at-home study drug dosing.  
The pre-dose laboratory assessments (chemistry, hematology, urinalysis) should be sent to the 
Central Laboratory for analysis. Under exceptional circumstances, the pre-dose laboratory 
assessments (chemistry, hematology, urinalysis) can be sent for expedited analysis at the local 
laboratory, along with duplicate samples sent to the Central Laboratory. The results of laboratory 
assessments should be available and reviewed by the Principal Investigator, or designee, prior to 
dosing the subject. 
Additionally, a urine sample will be collected for determination of baseline levels of composite 
biomarker panel for renal tubular injury, which is not part of eligibility determination. 
Subjects will return to the site for further assessments on Day 7 (-1 day) and Day 14 (±1 day) 
and the Follow-up visit (Day 21 [±1 day]). 
On Days 1, 7, 14, and 21, subjects will undergo safety monitoring consisting of reporting of AEs 
or SAEs, collection of vital signs including orthostatic vital signs, undergo a 12-lead ECG, and 
collection of urine for urinalysis and a composite biomarker panel for renal tubular injury, and 
blood for hematology, clinical chemistry, and plasma drug level. On Day 1, 7 and 14, all urine 
and blood collections should take place after the TETRAS-PS assessment.  Assessment of rating 
scales and upper limb wearable sensor measurements will also be performed. 
On Day 7 and Day 14, the subjects are instructed to ingest the first daily dose of CAD-1883 of 
300 mg (3 capsules of 100 mg each) at home 4 to 5 hours prior to the scheduled and/or 
anticipated dosing of the second daily dose of CAD-1883. The second daily dose of CAD-1883 
300 mg (3 capsules of 100 mg each) will be taken in the clinic, under the supervision of study 
staff, 4 to 5 hours after the first daily dose. 
 subjects will have the option to complete at-home assessments of tremor using 
the wearable sensor.

STUDY PROCEDURES 
•
Study procedures and their timing are summarized in the SOA (Appendix A, Table 2).
Protocol waivers or exemptions are not allowed.
•
Immediate safety concerns should be discussed with the Investigator, Medical Monitor,
and Sponsor immediately upon occurrence or awareness to determine if the subject
should continue or discontinue study intervention.
•
Adherence to the study design requirements, including those specified in the SOA
(Appendix A, Table 2), is essential and required for study conduct.
•
All screening evaluations must be completed and reviewed to confirm that potential
subjects meet all eligibility criteria. The Investigator will maintain a screening log to
record details of all subjects screened and to confirm eligibility or record reasons for
screening failure, as applicable. See Section 6.1.1 for information about re-screening
subjects.
6.1 
Study Visits 
The study period consists of Screening, Baseline/Pre-dose visit, treatment period, and Follow-up 
visit for a total study period that could be up to 56 days. Subjects will undergo a screening period 
of a minimum of 14 days up to a maximum of 35 days, a 1-day Baseline/Pre-dose visit, a Day 1 
visit that may occur up to 3 business days post the Baseline/Pre-dose visit, a treatment period for 
14 days (including Day 1), and a Follow-up visit at Day 21. All procedures and assessments will 
occur as indicated in the SOA (Appendix A, Table 2). 
6.1.1 
Screening Period 
Subjects will undergo a screening period of a minimum of 14 days up to a maximum of 35 days 
in which the subject will “wash-out” from prior tremorgenic and anti-tremor medications, to 
allow the effects of previous medication(s) on tremor to be eliminated. During the Screening 
period, each subject will undergo full assessment including medical and treatment history for ET, 
physical and neurological examination (including a focused neurological exam to include full 
assessment of tremor per Movement Disorder Society classification criteria (Bhatia, 2018)), in 
addition to laboratory testing, 12-lead ECG and other screening assessments as indicated in the 
SOA (Appendix A, Table 2). The diagnosis of ET must be established by the Principal 
Investigator at Screening based on the MDS criteria (Bhatia, 2018) with a documented severity 
of tremor based on the clinician-administered TETRAS-PS (Elble, 2012). 
Per the Investigator’s discretion, re-testing of any laboratory abnormality at the central lab or at a 
local lab is permissible, with prior approval from the Medical Monitor. 
Subjects who previously failed screening can be invited to re-screen up to two additional times, 
with recommendation by the Investigator and with approval by the Sponsor.

6.1.2 
Pre-dose (Baseline) Visit 
At the Baseline/Pre-dose visit, subjects will undergo all required procedures as indicated in the 
SOA (Appendix A, Table 2) including confirmation that all eligibility criteria are met. Analysis 
of the pre-dose laboratory assessments (chemistry, hematology, urinalysis) should be conducted 
by the Central Laboratory, with the results available and reviewed by the Principal Investigator, 
or designee, prior to dosing the subject with CAD-1883 (Day 1 visit). 
Under exceptional circumstances, the pre-dose laboratory assessments (chemistry, hematology, 
urinalysis) can be sent for expedited analysis at the local laboratory, along with duplicate 
samples sent to the Central Laboratory. The results of the above-referenced laboratory 
assessments should be available and reviewed by the Principal Investigator, or designee, prior to 
dosing the subject. 
Additionally, a urine sample will be collected for determination of baseline levels of composite 
biomarker panel for renal tubular injury, which is not part of eligibility determination. 
6.1.3 
Day 1 Visit (First In-Clinic Dosing) 
The Day 1 visit may occur up to 3 business days following the Baseline/Pre-dose visit. 
Baseline/Pre-dose laboratory assessments should be available and reviewed by Principal 
Investigator, or designee prior to dosing the subject with CAD-1883. 
On Day 1, subjects will be dosed in the clinic with the first dose of CAD-1883 300 mg 
(3 capsules of 100 mg each) and will be monitored in the clinic prior to ingesting the second dose 
of CAD-1883 300 mg (3 capsules of 100 mg each), 4 to 5 hours later. Additional safety and all 
efficacy assessments will be completed after the second in clinic dose on Day 1 as indicated in 
the SOA (Appendix A, Table 2). 
 Subjects will be dispensed study drug for continued twice-daily oral self-administration at home. 
6.1.4 
In-clinic Treatment Period Study Visits 
Subjects will return to the site for further assessments on Day 7 (-1 day) and Day 14 (±1 day) 
and a Follow-up visit (Day 21 [±1 day]). On Days 7 and 14, subjects are instructed to ingest the 
first daily dose of CAD-1883 of 300 mg (3 capsules of 100 mg each) at home 4 to 5 hours prior 
to the scheduled and/or anticipated dosing of the second daily dose of CAD-1883 in the clinic. 
The second daily dose of CAD-1883 300 mg (3 capsules of 100 mg each) will be taken in the 
clinic, under the supervision of study staff, 4 to 5 hours after the first daily dose, as indicated in 
the SOA (Appendix A, Table 2). 
6.1.5 
Intervals Between Site Visits 
Subjects will self-administer CAD-1883 300 mg (3 capsules of 100 mg each) twice-daily. 
Subjects are instructed to ingest the first daily dose of CAD-1883 at home. The second daily 
dose will be taken 8 hours (±2 hours) after the first daily dose. Each subject is provided with a 
medication diary to denote the date and time of at-home study drug dosing, as indicated in the 
SOA (Appendix A, Table 2).

SAFETY ASSESSMENTS 
7.1 
Adverse Events 
An AE is defined as any untoward medical occurrence in a clinical investigation subject 
administered a pharmaceutical product, which does not necessarily have a causal relationship 
with this treatment. An AE can therefore be any unfavorable and/or unintended sign (including 
an abnormal laboratory finding), symptom, or disease temporally associated with the use of an 
investigational medicinal product, whether or not related to the investigational medicinal 
product. All AEs, including observed or volunteered problems, complaints, or symptoms, are to 
be recorded on the appropriate eCRF. 
AEs, which include clinical laboratory test variables, will be monitored and documented from 
the time the subject signs the informed consent form (ICF) until Follow-up Day 21. Subjects 
should be instructed to report any AE that they experience to the Investigator, whether or not 
they think the event is due to study treatment. Beginning at Screening, the Investigators should 
make an assessment for AEs at each visit and record the event on the appropriate AE eCRF. 
Wherever possible, a specific disease or syndrome rather than individual associated signs and 
symptoms should be identified by the Investigator and recorded on the eCRF. However, if an 
observed or reported sign or symptom is not considered a component of a specific disease or 
syndrome by the Investigator, it should be recorded as a separate AE on the eCRF. Additionally, 
the condition that led to a medical or surgical procedure (e.g., surgery, endoscopy, tooth 
extraction, or transfusion) should be recorded as an AE, not the procedure itself.  
Any medical condition already present at Screening should be recorded as medical history and 
not be reported as an AE unless the medical condition or signs or symptoms present at pre-dose 
change in severity, frequency, or seriousness at any time during the study. In this case, it should 
be reported as an AE. 
Clinically significant abnormal laboratory or other examination (e.g., ECG) findings that are 
detected during the study or are present at Screening and significantly worsen during the study 
should be reported as AEs, as described below. The Investigator will exercise his or her medical 
and scientific judgment in deciding whether an abnormal laboratory finding or other abnormal 
assessment is clinically significant. Clinically significant abnormal laboratory values occurring 
during the clinical study will be followed until repeat tests return to normal, stabilize, or are no 
longer clinically significant. Abnormal test results that are determined to be an error should not 
be reported as an AE. Laboratory abnormalities or other abnormal clinical findings (e.g., ECG 
abnormalities) should be reported as an AE if any of the following are applicable: 
•
If an intervention is required as a result of the abnormality
•
If action is required to be taken with the study drug as a result of the abnormality
•
Based on the clinical judgment of the Investigator

7.1.1 
Assessment of Adverse Events by the Investigator 
The Investigator will assess the severity (intensity) of each AE as mild, moderate, or severe, and 
will also categorize each AE as to its potential relationship to study drug using the categories of 
‘yes’ or ‘no’. 
Assessment of severity: 
Mild – An event that is easily tolerated and generally not interfering with normal daily activities. 
Moderate – An event that is sufficiently discomforting to interfere with normal daily activities. 
Severe – An event that is incapacitating with inability to work or perform normal daily activities. 
Causality assessment: 
The relationship of an AE to the administration of the study drug is to be assessed according to 
the following definitions: 
No (unrelated, not related, unlikely to be related) – The time course between the administration 
of study drug and the occurrence or worsening of the AE rules out a causal relationship and 
another cause (concomitant drugs, therapies, complications, etc.) is suspected. 
Yes (possibly, probably, or definitely related) – The time course between the administration of 
study drug and the occurrence or worsening of the AE is consistent with a causal relationship and 
no other cause (concomitant drugs, therapies, complications, etc.) can be identified. 
The definition implies a reasonable possibility of a causal relationship between the event and the 
study drug. This means that there are facts (evidence) or arguments to suggest a causal 
relationship. 
The following factors should also be considered: 
•
The temporal sequence from study drug administration-
The event should occur after the study drug is given. The length of time from study drug 
exposure to event should be evaluated in the clinical context of the event. 
•
Underlying, concomitant, intercurrent diseases-
Each report should be evaluated in the context of the natural history and course of the disease 
being treated and any other disease the subject may have. 
•
Concomitant drug-
The other drugs the subject is taking or the treatment the subject receives should be examined 
to determine whether any of them might be recognized to cause the event in question. 
•
Known response pattern for this class of study drug-
Clinical and/or preclinical data may indicate whether a particular response is likely to be a 
class effect. 
•
Exposure to physical and/or mental stresses-
The exposure to stress might induce adverse changes in the recipient and provide a logical 
and better explanation for the event.

7.2 
Serious Adverse Events 
An AE or adverse reaction is considered serious if, in the view of either the Investigator or the 
Sponsor, it results in any of the following outcomes: 
•
Death
•
A life-threatening AE
Note: An AE or adverse reaction is considered “life-threatening” if, in view of either the 
Investigator or the Sponsor, its occurrence places the subject at immediate risk of death. It 
does not include an event that, had it occurred in a more severe form, might have caused 
death. 
•
Requires hospitalization or prolongation of existing hospitalizations
Note: Any hospital admission with at least one overnight stay will be considered an inpatient 
hospitalization. An emergency room or urgent care visit without hospital admission will not 
be recorded as a SAE under this criterion, nor will hospitalization for a procedure scheduled 
or planned before signing of informed consent, or elective treatment of a pre-existing 
condition that did not worsen from Baseline. However, unexpected complications and/or 
prolongation of hospitalization that occur during elective surgery should be recorded as AEs 
and assessed for seriousness. Admission to the hospital for social or situational reasons (i.e., 
no place to stay, live too far away to come for hospital visits, respite care) will not be 
considered inpatient hospitalizations.  
•
A persistent or significant disability/incapacity or substantial disruption of the ability to
conduct normal life functions
•
A congenital anomaly/birth defect
•
An important medical event.
Note: Important medical events that do not meet any of the above criteria may be considered 
an SAE when, based upon appropriate medical judgment, they may jeopardize the subject 
and may require medical or surgical intervention to prevent one of the outcomes listed above. 
Examples of such medical events include allergic bronchospasm requiring intensive 
treatment in an emergency room or at home, blood dyscrasias or convulsions that do not 
result in inpatient hospitalizations, or the development of drug dependency. 
7.3 
Serious Adverse Event Reporting − Procedures for Investigators 
Initial Reports 
All SAEs occurring from the time the subject signs the informed consent until 30 days following 
the last administration of study drug must be reported to CRO within 24 hours of the knowledge 
of the occurrence. After the 30-day reporting window, any SAE that the Investigator considers 
related to study drug must be reported to CRO or designee. 
To report the SAE, complete the AE form electronically in the eCRF for the study and then the 
paper SAE report form. Send the paper SAE report form via email to the CRO

within 24 hours of awareness regardless of the relationship to the study drug. The 
SAE report form should be completed as thoroughly as possible; however, submission of the 
report should not be delayed if information is not available at the time of the initial report.  
Follow-Up Reports 
The Investigator must continue to follow the subject until the SAE has subsided or until the 
condition becomes chronic in nature, stabilizes (in the case of persistent impairment), or the 
subject dies. 
Within 24 hours of receipt of follow-up information, the Investigator must update the paper SAE 
report form and the AE form electronically in the eCRF and submit any supporting 
documentation (e.g., patient discharge summary or autopsy reports) to CRO via fax or email.  
7.4 
Pregnancy Reporting 
If a subject becomes pregnant during the study, the Investigator is to stop dosing with study drug 
immediately and the subject should be withdrawn from the study. Early Termination study visit 
procedures as indicated in the SOA should be implemented at that time.  
A pregnancy is not considered to be an AE or SAE; however, it must be reported to the CRO 
within 24 hours of knowledge of the pregnancy during the study or up to 90 days after the last 
dose of study drug via the Pregnancy Data Collection Form. The Investigator must complete the 
Pregnancy Data Collection Form and fax or email it to the CRO (contact information listed in 
Section 7.6).  
If the female partner of a male subject becomes pregnant while the subject is receiving study 
drug or up to 90 days after the last dose of study drug, the Investigator should notify the CRO as 
described above.  
The pregnancy should be followed until the outcome of the pregnancy, whenever possible. Once 
the outcome of the pregnancy is known, the Pregnancy Data Collection Form should be 
completed and faxed or emailed to the CRO (contact information listed in Section 7.6). If the 
outcome of the pregnancy meets the criteria for immediate classification as an SAE (i.e., 
postpartum complication, spontaneous abortion, stillbirth, neonatal death, or congenital 
anomaly), the Investigator should follow the procedures for reporting an SAE. 
7.5 
Expedited Reporting 
The CRO will report all relevant information about Suspected Unexpected Serious Adverse 
Reactions (SUSAR) that are fatal or life-threatening as soon as possible to the Food and Drug 
Administration (FDA), and in any case no later than 7 days after knowledge by the CRO of such 
a case. Relevant follow-up information will subsequently be communicated within an additional 
8 days.  
All other SUSARs will be reported to the FDA as soon as possible but within a maximum of 
15 days of first knowledge by the CRO.  
The CRO will also report any additional expedited safety reports required in accordance with the 
relevant timelines.  
The CRO will also inform all Investigators as required per local regulation.

The requirements above refer to the requirements relating to investigational medicinal product. 
7.6 
Special Situation Reports 
Special situation reports include reports of overdose, misuse, abuse, medication error, and reports 
of adverse reactions associated with product complaints. 
•
Overdose: Refers to the administration of a quantity of a medicinal product given per
administration or cumulatively (accidentally or intentionally), which is above the
maximum recommended dose according to the protocol. Clinical judgement should
always be applied. In cases of a discrepancy in the drug accountability, overdose will be
established only when it is clear that the subject has taken additional dose(s), or the
Investigator has reason to suspect that the subject has taken additional dose(s).
•
Misuse: Refers to situations where the medicinal product is intentionally and
inappropriately used that is not in accordance with the protocol instructions or local
prescribing information and may be accompanied by harmful physical and/or
psychological effects.
•
Abuse: Is defined as persistent or sporadic, intentional excessive use of a medicinal
product, which is accompanied by harmful physical or psychological effects.
•
Medication error: Is any unintentional error in the prescribing, dispensing, or
administration of a medicinal product by a healthcare professional, subject, or consumer,
respectively. The administration or consumption of the unassigned treatment and
administration of an expired product are always reportable as medication errors. Cases of
subjects missing doses of investigational product are not considered reportable as
medication error.
All special situation events as described above must be reported on the Special Situations Report 
form and faxed or emailed to the CRO (contact information listed below) within 24 hours of 
knowledge of the event. All AEs associated with these Special Situation reports should be 
reported as AEs or SAEs as well as recorded on the AE eCRF and/or the paper SAE report form. 
Details of the symptoms and signs, clinical management, and outcome should be provided, when 
available.

Investigators should pay special attention to clinical signs related to previous serious illnesses. 
Neurological examinations will include assessment of mental status, cranial nerves, motor, 
sensory, reflexes, coordination, and gait. In addition to the complete neurological exam, a 
focused neurological exam is conducted during the Screening visit to include full assessment of 
tremor per Movement Disorder Society classification criteria (Bhatia, 2018). 
Physical and neurological exams will be conducted at timepoints indicated in the SOA 
(Appendix A, Table 2). 
7.8 
Electrocardiograms 
Triplicate 12-lead ECG will be obtained as indicated in the SOA (Appendix A, Table 2), using an 
ECG machine that automatically calculates the heart rate and measures PR, QRS, QT, and QTcF 
intervals. ECGs are to be assessed prior to vital signs and blood sampling for laboratory tests. 
Triplicate ECG recordings will be taken, after a minimum of 5 minutes of rest in supine position: 
3 consecutive recordings will be made in succession, no more than 2 minutes apart. The full set of 
triplicates should be completed in less than 4 minutes. These ECGs will be read by the Investigator 
to rule out any clinically significant findings. An ECG is to be taken at the Screening, Baseline/Pre-
dose, Day 1, Day 7, Day 14 and Day 21 Follow-up visits. At the Day 1, Day 7 and Day 14 visits, 
ECGs are to be obtained at the following time points: 30min, 60min, and 2 hours following the 
first dose of the day and again 30 min, 60 min, 2 hours and 4 hours after the second dose of study 
drug in the clinic.  On Days 7 and 14, an ECG is to be taken at 30 min, 60 min, 2 hours, and 4 
hours following the dose of study drug in the clinic. There is a +/- 5-minute allowable window for 
these ECGs.  
After a minimum of 5 minutes of rest in supine position, 3 consecutive recordings should be 
made in succession, no more than 2 minutes apart. The full set of triplicates should be completed 
in less than 4 minutes. These ECGs will be read by the Investigator to rule out any clinically 
significant findings. 
7.9 
Vital Signs 
Vital signs (VS) assessments (to be taken before blood collection for laboratory tests) will be 
assessed and include blood pressure (systolic and diastolic), heart rate, respiratory rate and oral 
temperature.  Vital signs are to be taken at the Screening, Baseline/Pre-dose, Day 1, Day 7, Day 
14 and Day 21 Follow-up visits. The vital signs on Day 1 are to be taken at 30min, 60min, and 2 
hours following the first dose of the day and again 30 min, 60 min, 2 hours and 4 hours after the 
second dose of study drug in the clinic.  On Days 7 and 14, the vital signs are to be taken at 30 
min, 60 min, 2 hours, and 4 hours following the dose of study drug in the clinic. There is a +/- 5-
minute allowable window for these vital signs.  
7.10 
Orthostatic Vital Signs 
Orthostatic vital signs will be measured at Screening, Baseline, Day 1, Day 7, Day 14 and during 
the Follow-up visit.

During the Screening visit, orthostatic VS measurements will be done once, at any time during 
the visit. 
During the Baseline/Pre-Dose visit, baseline orthostatic VS will include 3 separate measurements 
with each measurement of blood pressure and heart rate separated from the next by at least 
15-20 minutes apart, to minimize the potential impact of biological variability of a single 
baseline measurement. The average of the 3 baseline orthostatic VS measurements will be used 
for comparison to all post-treatment measurements. 
During Day 1, orthostatic VS measurements will be done twice, 2 to 4 hours following each in-
clinic dose. 
During Day 7 and Day 14 visits, orthostatic VS measurements will be done once, 2 to 4 hours 
following the in-clinic dose. 
During the Follow-up visit, orthostatic VS measurements will be done once, at any time during 
the visit. 
Orthostatic VS must be assessed using an appropriate device, and the arm position must be 
standardized for each subject. These measurements are to be taken in the same arm for the 
duration of the study. The position of the cuff on the arm should be in line with the heart with the 
arm lying next to the subject when semi-supine and should be in line with the heart at 
approximately a 45 degrees angle from horizontal for the standing measure. 
In order to obtain orthostatic VS, the subjects will undergo the following procedures in 
sequential order: 
1. The subject will rest in a supine or semi-supine position for at least 5 minutes. 
2. After remaining supine or semi-supine for 5 minutes, one measurement of blood pressure and 
heart rate will be taken. 
3. The subject will then be asked to sit on the edge of the bed/chair with feet on the floor (or 
with feet dangling from the bed/chair depending on the height of the bed/chair) for 
approximately 30 seconds. 
4. The person performing the assessment will then ask the question, “Are you ready to 
stand?” 
• If the subject responds in the affirmative, the subject will proceed to stand and 
then be asked to remain standing for 2 minutes. After standing for 2 minutes, blood pressure and 
heart rate will be recorded. 
• If the subject states that he or she is not ready to stand, the subject will be allowed to sit 
as positioned for one additional minute and will be asked again if they are ready to stand. 
The subject will proceed to stand. After standing for 2 minutes, one measurement will be 
taken for blood pressure and heart rate. 
• If the individual is still unable to stand, vital signs will be measured while the subject is 
in an upright seated position.

Orthostatic hypotension will be defined as a reduction in SBP of 20 mmHg or more, and/or a 
reduction in DBP of 10 mmHg or more, for the standing measurement compared to the supine or 
semi-supine measurement. If orthostatic hypotension is suspected, the measurement process may 
be repeated at the Investigator’s discretion. Any confirmed orthostatic hypotension or clinically 
significant measurements that are associated with clinical symptoms will be recorded as adverse 
events. 
If routine VS and orthostatic VS coincide at the same time points, the same values for routine VS 
(blood pressure and heart rate) during the supine or semi-supine position should be recorded in 
the CRFs as the same values of the start of orthostatic VS in the supine or semi-supine position. 
7.11 
Clinical Laboratory Evaluations 
A list of clinical laboratory tests to be performed is in Appendix B. See Table 2, SOA in 
Appendix A for the timing and frequency. 
The Investigator must review the laboratory report, document this review, and record any 
clinically relevant changes occurring during the study in the AE section of the eCRF. The 
laboratory reports must be filed with the source documents. Clinically significant abnormal 
laboratory findings are those which 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 considered clinically significantly abnormal during participation 
in the study or within 30 days after the last dose of study intervention should be repeated until 
the values return to normal or 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 CRO notified.
•
All protocol-required laboratory assessments, as defined in Appendix B, must be
conducted in accordance with the laboratory manual and the SOA (Table 2).
•
If laboratory values from non-protocol specified laboratory assessments performed at the
institution’s local laboratory require a change in the subject’s management or are
considered clinically significant by the Investigator (e.g., SAE or AE or dose
modification), then the results must be recorded as an AE in the eCRF for AEs and also
the paper form if an SAE.
•
On Days 1, 7, 14 all clinical laboratory samples should be collected after the TETRAS-
PS assessment

Columbia Suicide Severity Rating Scale (C-SSRS) 
The C-SSRS is a questionnaire that prospectively assesses Suicidal Ideation and Suicidal 
Behavior. The C-SSRS, which uses a semi-structured interview to probe subject responses, will 
be administered by an individual who has received training and certification in its administration. 
At the Baseline/Pre-dose visit, the “baseline” version of the C-SSRS will be administered. This 
version assesses Suicidal Ideation and Suicidal Behavior during the subject’s lifetime and during

EFFICACY ASSESSMENTS 
8.1 
Rating Scales 
The treatment effect will be evaluated by means of the TETRAS-PS (Version 3.1), which is a 
validated scale that has been used in recently conducted clinical trials in subjects with ET (Elble, 
2012). It provides an accurate reflection of the clinical response to treatment on the amplitude of 
tremor over multiple bodily locations and over time. 
The TETRAS assessments at Screening, Baseline/Pre-dose, Days 1, 7, 14, and Follow-up visit 
(Day 21) will be administered by a certified rater. TETRAS raters at each site must demonstrate 
expertise in the administration of the TETRAS according to criteria preset by independent 
central rating experts. The TETRAS raters at each site can be the Principal Investigator or a staff 
member delegated as a rater by the Principal Investigator. Each site must make every effort, to 
the extent that is possible, to ensure availability of a primary rater and a backup rater to perform 
all TETRAS assessments on the same subjects throughout the study duration. 
The TETRAS-PS assessments at the Screening visit, Baseline/Pre-dose, Days 1, 7, 14, and 21 
clinic visits will be recorded using videography for centralized evaluation and rating by 
independent blinded central raters (neurologists) with expertise in the assessment of ET. 
On Screening and Baseline/Pre-dose visits: TETRAS-PS, 
are performed. 
On Day 1: The TETRAS-PS will be administered 2 to 4 hours following the second in-clinic 
dose.  
On Day 7: the TETRAS-PS, 
will be performed 
2 to 4 hours following the in-clinic dose. 
On Day 14: the TETRAS-PS, 
 will be performed 
2 to 4 hours following the in-clinic dose.

performed once any time during the visit. 
8.2 
Wearable Sensor 
In addition to the assessment of efficacy via rating scales, treatment effect will be evaluated by 
measuring tremor with a sensor worn on the upper limb (index finger). These assessments will be 
conducted during the clinic visits and optionally at-home. 
8.2.1 
In-Clinic Assessment 
The wearable sensor measurements of upper limb tremor assessments will be completed in the 
clinic once at any time during the Screening visit and at two different times during the 
Baseline/Pre-dose site visit. 
During the site visit on Day 1 the wearable sensor measurements of upper limb tremor will be 
captured once, 2 to 4 hours following the second in-clinic dose. 
During the site visit on Days 7 and 14, the wearable sensor measurements of upper limb tremor 
will be captured once, 2 to 4 hours following the in-clinic dose. 
During the Follow-up visit (Day 21), the wearable sensor measurements of upper limb tremor 
will be completed at any time during the visit. 
In-clinic assessments will be obtained during the performance of 4 maneuvers: 
1. extended arms posture,
2. wing-beating posture,
3. kinetic “finger-to-chin” movement, and
4. arm on table posture.
These assessments will be performed twice, once with the sensor on the left index finger and 
once with the sensor on the right index finger.  
In addition, the subject will wear the sensor on the index finger of each hand while performing 
3 activities of daily living:  
1. pouring from a cup,
2. drinking from a cup, and
3.
eating with a spoon

The Baseline/Pre-dose visit is the last day of the Screening period. The Baseline/Pre-dose visit must be conducted in the afternoon. 
2
. 
3 
In addition to the complete neurological exam, a focused neurological exam is conducted during the Screening visit to include full assessment of tremor per 
Movement Disorder Society classification criteria (Bhatia, 2018). 
4 
Complete PE at Screening, Days 1, 7, and 14 (includes: General; HEENT; Cardiovascular; Respiratory; Abdomen; Skin; Extremities; Lymphatic system and 
Musculoskeletal); symptom-based PE at Baseline/Pre-dose and Day 21 Follow-up visit (includes: General, HEENT, Cardiovascular, Respiratory, Abdomen, Skin, 
Extremities). 
5
6
Triplicate ECG recordings, after a minimum of 5 minutes of rest in supine position: 3 consecutive recordings will be made in succession, no more than 2 minutes 
apart. The full set of triplicates should be completed in less than 4 minutes. These ECGs will be read by the Investigator to rule out any clinically significant 
findings. ECGs are to be performed prior to vital signs and blood sampling. 
7 
Blood pressure (systolic and diastolic), heart rate, respiratory rate and oral temperature. 
8 
Obtained prior to dosing and post dosing at 30min, 60min, 2 hours and 4 hours following the dose of study drug in the clinic. For Day 1, this is to be done 
Baseline/Pre-dose and 30min, 60min, and 2 hours after the first dose in the clinic, and again 30 min, 60 min, 2 hours, and 4 hours after the second dose in the 
clinic. There is a +/- 5-minute allowable time window for these assessments.  ECG to be done before the corresponding vital sign measurements. 
9  For details re: orthostatic vital signs measurements, refer to Section 7.10. 
10  Urinalysis includes: Bilirubin, Blood, Creatinine, Glucose, Ketones, Leukocyte esterase, Microscopy, Nitrite, pH, Protein, Specific gravity, Microalbumin and

11   A serum pregnancy test is done at Screening only. 
12  A urine pregnancy test is done at Baseline/Pre-dose, Days 7, 14, and 21. 
13 
14    The subject should be instructed to self-administer their first daily dose of CAD-1883 4 to 5 hours prior to the scheduled and/or anticipated dosing of the second 
daily dose of CAD-1883. The second daily dose of CAD-1883 should be taken in the clinic 4 to 5 hours after the first daily dose.

16 
17
18  TETRAS Performance Subscale assessments at Screening, Baseline/Pre-dose, Days 1, 7, 14, and 21 will be recorded via videography for central rating. 
19 Screening:
20  Performed between 2-4 hours following the second dose in the clinic. 
21  Performed between 2-4 hours following the second daily dose in the clinic. 
22  Wearable sensor measurement of upper-limb tremor will be captured once at the site, at any time during Screening and Day 21. 
23 Wearable sensor measurements of upper limb tremor will be captured at two different times during the Baseline/Pre-dose visit. 
24  Wearable sensor measurements of upper limb tremor will be captured once, 2 to 4 hours following the in-clinic dose.  For Day 1, this is to be done 2-4 hours after 
the 2nd in-clinic dose. 
25  At the Baseline/Pre-dose visit, the “baseline” version of the C-SSRS will be administered. This version assesses Suicidal Ideation and Suicidal Behavior during the 
subject’s lifetime and during a predefined period. At the Day 21 visit (and the Early Termination visit for subjects withdrawing early), the “since last visit” version 
will be administered. The C-SSRS does not need to be completed at the Day 14 visit if it is not an Early Termination visit. During Early Termination visit, the 
subject will not receive study drug, will undergo all required procedures as well as the C-SSRS. 
26  Both doses of study drug are to be administered in the clinic with the second dose being administered 4-5 hours after the first.  
27  All laboratory collections on Days 1, 7, 14 should be performed after the TETRAS-PS assessment.

Overall Study Design and Plan
3.1. 
Overall Design 
This is an open-label study designed to evaluate the safety, tolerability, and efficacy of 
CAD-1883 administered twice daily orally to adult subjects with ET. The diagnosis of ET must 
be established by the Principal Investigator at Screening based on the Movement Disorder 
Society (MDS) criteria with a documented severity of tremor based on the clinician-administered 
TETRAS-PS.
 Subjects will 
undergo a screening period of a minimum of 14 days up to a maximum of 35 days in which the 
subject will washout from prior
 medications, to allow the effects of 
previous medication(s)
 to be eliminated. Subjects will return to the site for further 
assessments on Day 7 (-1 day) and Day 14 (±1 day) and a Follow-up visit (Day 21 [±1 day]). 
The wearable sensor measurements of upper limb tremor assessments will be completed in the 
clinic once at any time during the Screening visit and at two different times during the 
Baseline/Pre-dose site visit. 
subjects will have the option to complete at-home 
assessments of tremor using the wearable sensor 
3.2. 
Sample Size and Power 
Up to 30 subjects will be enrolled. No formal statistical power analysis was conducted. 
3.3. 
Study Population 
This study includes subjects between 18 and 75 years old, inclusive, with a history of tremor for 
at least 3 years. 
3.4. 
Treatments Administered 
The study will be open-label consisting of 1 treatment group receiving 300 mg twice-daily oral 
dosing of CAD-1883 for a treatment period of 14 days. Dose intervals on Days 1, 7 and 14 are 
changed from the protocol amendment 1 through 3. Subjects enrolled under the protocol 
amendment 1 take the first dose of CAD-1883 300 mg (3 capsules of 100 mg each) at the site, 
2nd dose are taken 8 hours (±2 hours) after the first dose. On Days 7 and 14, the subjects are 
instructed to ingest the first daily dose of CAD-1883 of 300 mg at home. The second daily dose 
are taken in the clinic 8 hours (±2 hours) after the first daily dose. For subjects enrolled under 
the protocol amendment 2 and 3 the first dose on Day 1 is taken in clinic and the second dose is 
taken 4 to 5 hours later. On Days 7 and 14, the first daily dose is taken at home and the second 
daily dose is taken in the clinic 4 to 5 hours later. 
3.5. 
Method of Assigning Subjects to Treatment Groups 
There is 1 treatment group. Eligible subjects are enrolled sequentially.  There was no 
randomization, blinding, or stratification employed in this study.

3 
In addition to the complete neurological exam, a focused neurological exam is conducted during the Screening visit to include full assessment of tremor per 
Movement Disorder Society classification criteria (Bhatia, 2018). 
4 
Complete PE at Screening, Days 1, 7, and 14 (includes: General; HEENT; Cardiovascular; Respiratory; Abdomen; Skin; Extremities; Lymphatic system and 
Musculoskeletal); symptom-based PE at Baseline/Pre-dose and Day 21 Follow-up visit (includes: General, HEENT, Cardiovascular, Respiratory, Abdomen, 
Skin, Extremities). 
5
6
Triplicate ECG recordings, after a minimum of 5 minutes of rest in supine position: 3 consecutive recordings will be made in succession, no more than 2 
minutes apart. The full set of triplicates should be completed in less than 4 minutes. These ECGs will be read by the Investigator to rule out any clinically 
significant findings. ECGs are to be performed prior to vital signs and blood sampling.

Obtained prior to dosing and post dosing at 30min, 60min, 2 hours and 4 hours following the dose of study drug in the clinic. For Day 1, this is to be done 
Baseline/Pre-dose and 30min, 60min, and 2 hours after the first dose in the clinic, and again 30 min, 60 min, 2 hours, and 4 hours after the second dose in the 
clinic. There is a +/- 5-minute allowable time window for these assessments.  ECG to be done before the corresponding vital sign measurements. 
9  For details re: orthostatic vital signs measurements, refer to Section 7.10. 
10  Urinalysis includes: Bilirubin, Blood, Creatinine, Glucose, Ketones, Leukocyte esterase, Microscopy, Nitrite, pH, Protein, Specific gravity, Microalbumin and 
Urobilinogen 
11   A serum pregnancy test is done at Screening only.  
12  A urine pregnancy test is done at Baseline/Pre-dose, Days 7, 14, and 21. 
13 
14    The subject should be instructed to self-administer their first daily dose of CAD-1883 4 to 5 hours prior to the scheduled and/or anticipated dosing of the 
second daily dose of CAD-1883. The second daily dose of CAD-1883 should be taken in the clinic 4 to 5 hours after the first daily dose.

18  TETRAS Performance Subscale assessments at Screening, Baseline/Pre-dose, Days 1, 7, 14, and 21 will be recorded via videography for central rating. 
19 Screening: 
20  Performed between 2-4 hours following the second dose in the clinic. 
21  Performed between 2-4 hours following the second daily dose in the clinic. 
22  Wearable sensor measurement of upper-limb tremor will be captured once at the site, at any time during Screening and Day 21. 
23 Wearable sensor measurements of upper limb tremor will be captured at two different times during the Baseline/Pre-dose visit. 
24  Wearable sensor measurements of upper limb tremor will be captured once, 2 to 4 hours following the in-clinic dose.  For Day 1, this is to be done 2-4 hours 
after the 2nd in-clinic dose. 
25  At the Baseline/Pre-dose visit, the “baseline” version of the C-SSRS will be administered. This version assesses Suicidal Ideation and Suicidal Behavior 
during the subject’s lifetime and during a predefined period. At the Day 21 visit (and the Early Termination visit for subjects withdrawing early), the “since 
last visit” version will be administered. The C-SSRS does not need to be completed at the Day 14 visit if it is not an Early Termination visit. During Early 
Termination visit, the subject will not receive study drug, will undergo all required procedures as well as the C-SSRS. 
26  (Protocol Amendment 3) Both doses of study drug are to be administered in the clinic with the second dose being administered 4-5 hours after the first. 
27 All laboratory collections on Days 1, 7, 14 should be performed after the TETRAS-PS assessment.

Statistical Analysis and Reporting
4.1. 
Introduction 
Data processing, tabulation of descriptive statistics, calculation of inferential statistics, and 
graphical representations will be performed primarily using SAS (release 9.4 or higher). 
If the use of other 
software is warranted, the final statistical methodology report will detail what software was used 
for what purposes. 
Continuous (quantitative) variable summaries will include the number of subjects (n) with 
non-missing values, mean, standard deviation (SD), median, minimum, and maximum. 
Categorical (qualitative) variable summaries will include the frequency and percentage of 
subjects who are in the particular category for each possible value. In general, the denominator 
for the percentage calculation will be based upon the total number of subjects in the study 
population, unless otherwise specified. The denominator for by-visit displays will be the number 
of subjects in the relevant study population with non-missing data at each visit. If there is any 
missing value for a categorical analysis, a “Missing” category will be displayed as the last 
category in the table for the variable. 
For weight, height, 
 one decimal place will be used for all summary 
statistics.  For all other summaries, the minimum and maximum will be reported with the same 
degree of precision (i.e., the same number of decimal places) as the observed data. Measures of 
location (mean and median) and confidence interval boundaries will be reported to 1 degree of 
precision more than the observed data, up to 3 decimal places. Measures of spread (SD) will be 
reported to 2 degrees of precision more than the observed data, up to 3 decimal places. 
Percentages will be presented to 1 decimal place, unless otherwise specified. Percentages 
equaling 0 or 100 will be displayed with no decimal places or percentage symbols. 
Fractional numeric values will be presented with a zero to the left of the decimal point (for 
example, 0.12 – 0.30). 
Unless otherwise indicated, all statistical tests will be conducted at the 0.05 significance level 
using 2-tailed tests, and P values will be reported. Corresponding 95% confidence intervals (CIs) 
will be presented for statistical tests, where applicable. 
4.2. 
Interim Analysis and Data Monitoring 
There will be no interim analyses in this study. 
5.
Analysis Populations
The following analysis populations are planned for this study: 
•
Safety Population: The Safety population includes all subjects who took at least 1 dose
of study drug, regardless of the Protocol Amendment under which subjects were enrolled.
This population will be used to summarize all safety data.

•
Full Analysis Set (FAS): The FAS consists of subjects in the Safety Population at least
one TETRAS-PS assessment Total Score at Day 7, Day 14 or early termination visit. The
FAS will be used to summarize all efficacy data.
•
Per-Protocol Population: The Per-Protocol Population includes all subjects in the FAS
who did not have any major protocol deviation and follow the study protocol for
TRETRAS-PS assessment at Day 14 or ET visit.

General Considerations for Statistical Analysis
6.1. 
Statistical Definitions and Algorithms 
6.1.1. Baseline 
The last non-missing observed value recorded on or before the date of the first dose of treatment 
at the Pre-dose visit will be used as the baseline observation for all calculations of change from 
baseline.  
Wearable sensor measurements of upper limb tremor will be captured at 2 different times during 
the Pre-dose visit (Visit 2); the average of the 2 assessments will be used as the baseline 
observation for all calculations of change from baseline in wearable sensor assessments.  
During the Pre-dose visit, baseline orthostatic vital signs will include 3 separate measurements, 
and the average of the 3 (or fewer if missing data occur) baseline orthostatic vital signs 
measurements will be used as baseline for comparison to all post-treatment measurements. 
6.1.2. Categorization of Subjects 
All subjects will be categorized into the following 2 groups based on under which protocol 
amendment they were enrolled: 
•
Cohort-1: Subjects enrolled under Protocol Amendment 1.0
•
Cohort-2: Subjects enrolled under Protocol Amendment 2.0 or 3.0
All analyses will be presented overall and by cohort.

6.1.4. Multiple Comparisons 
6.1.5. Handling of Dropouts or Missing Data 
There was no replacement for subjects who had withdrawn from the study or were lost to follow 
up. Individual items of TETRAS-PS,
, and Kinesia scores will not be imputed as 
described in Section 6.1.8. 
6.1.6. Analysis Visit Windows 
Visits will be analyzed as scheduled. Unscheduled and/or repeated measurements will only be 
included if a scheduled measurement is not available and the unscheduled/repeated measurement 
falls within the analysis visit windows as described in Table 2. The windows follow the Schedule 
of Events in Table 1. Unscheduled/repeated measurements will be listed. Study day is defined in 
Section 6.1.8.

•
TETRAS-PS Total score = sum of the 16 individual item scores (only the maximum of
the item 5 lower limb tremor scores will be counted), with a maximum total score of 64.
There will be no missing value imputation performed.
•
TETRAS-PS Upper Limb Subscale score = sum of the item 4, item 6, item 7 and item
8 scores (forward outstretched postural tremor, lateral “wing beating” postural tremor,
kinetic tremor, Archimedes spirals, and dot approximation task from both sides of the
body, as well as handwriting), with a maximum total score of 44. There will be no
missing value imputation performed.
•
TETRAS-PS Upper Limb Tremor (Item 4) Total score = sum of the 6 individual
scores under item 4 scores (forward outstretched postural tremor, lateral “wing beating”

postural tremor, and kinetic tremor scores for left and right hand, respectively) from both 
sides of the body, with a maximum total score of 24. There will be no missing value 
imputation performed. 
•
Kinesia Upper Limb Tremor score = sum of the scores from the extended arms posture,
wing-beating posture, and kinetic “finger-to-chin” wearable sensor maneuvers from both
sides of the body, with a maximum total score of 24. There will be no missing value
imputation performed.
•
Change from baseline = value at current time point – value at baseline.
• For calculation of change from baseline to Day 14 for discontinued subjects their
assessment value at the early termination (ET) visit should be used
•
Percent change from baseline = (change from baseline / baseline) * 100. If both
baseline and change from baseline are 0 then percent change from baseline will be set to
0.
•
Study day = number of days relative to the first dose date of study drug and will be
calculated using the following formulas:
For pre-dose: study day= Start Date/ Stop Date – first dose date;
For post-dose: study day= Start Date/ Stop Date – first dose date + 1.
•
TEAE (treatment-emergent AE) = any AE with an onset date/time after the first dose
of treatment. If an AE was present at baseline and worsened on or after the first dose of
treatment it will be considered a TEAE.
•
Orthostatic hypotension is defined as a reduction in SBP of 20 mmHg or more, and/or a
reduction in DBP of 10 mmHg or more, for the standing measurement compared to the
supine or semi-supine measurement.
•
Time since first ET symptom = Day 1 (Visit 3) date - Date of first ET symptom as
recorded on the Disease History case report form (CRF) + 1
•
Time since ET diagnosis = Day 1 (Visit 3) date - Date of ET diagnosis as recorded on
the Disease History case report form (CRF) + 1
•
Study drug compliance (capsule count) = total number of capsules taken / total number
of expected doses from the first dose date to the last dose date, inclusive * 100%.

•
Number of expected doses for subjects who completed study treatment = number of
capsules taken at the clinic + number of capsules dispensed for self-administration at
home = [Day 14 (Visit 5) date – Day 1 (Visit 3) date + 1] x 6 capsules/day
Expected doses are summed up to the point of discontinuation (eg, if a subject
discontinued, only planned doses up to that discontinuation day are counted in the
denominator).
•
Number of capsules taken =  number of expected doses - number of capsules lost -
number of unused capsules returned at next clinic visit, as collected in the case report
form (CRF).
For subjects who discontinued and did not return remaining capsules, the number of
capsules taken will include all doses up to the last dose the subject reported, or the
discontinuation date (the second dose on that day will be excluded in this calculation).
For treatment completers with additional treatment (for example the subject received
study treatments for 15 days) their number of expected doses remains 84. Thus, the
resulting compliance rate will likely be over 100%.
6.1.9. Data Adjustments/Handling/Conventions 
All collected data will be presented in listings. Data not subject to analysis according to this plan 
will not appear in any tables or graphs but will be included in the data listings. 
All P values will be displayed in three decimals and rounded using standard scientific notation (eg, 
0.XXX). If a P value less than 0.001 occurs, it will be shown in tables as <0.001.
Adverse events and medical histories will be coded using the Medical Dictionary for Regulatory 
Activities (MedDRA) version 21.1 thesaurus or higher. Concomitant medications will be coded 
using WHO Global B3 September 1, 2018. 
A treatment-related AE is any AE with a relationship to the study drug of possibly, probably, or 
definitely related. 
If partial AE or medication dates occur, the convention for replacing missing dates for the 
purpose of statistical analysis is as follows:  
For partial AE and medication start dates: 
•
If the year is unknown, then do not impute the date but assign a missing value.
•
If the year is known, but the month or month and day is unknown, then:
o
If the year matches the year of first dose date and the end date (if present) is after
first dose date, then impute as the month and day of the first dose date.
o
Otherwise, assign 01 January.

 Page 20 of 151 
•
If the year and month are known, but the day is unknown, then:
o
If the month and year match the month and year of the first dose date, then impute
as the day of the first dose date.
o
Otherwise, assign 01.
For partial AE and medication end dates: 
•
If the year is unknown, then do not impute the date but assign as missing value.
•
If the year is known, but the month or month and day is unknown, then:
o
If the year matches the year of the last date of the study (date of last contact if
subject lost to follow-up; date of completion or early termination otherwise), then
impute as the month and day of the last date of the study.
o
Otherwise, assign 31 December.
•
If the year and month are known, but the day is unknown, then:
o
If the month and year match the month and year of the last date of the study, then
impute as the day of the last date of the study.
o
Otherwise, assign the last day of the month.
If partial times occur, the convention is as follows: 
•
if the missing time occurs on the day of the first dose and both the hour and minute are
missing then the time assigned is the time of the first dose, otherwise if both the hour and
minute are missing and the date is not the date of first dose the time assigned is 12:00;
•
if the date is the same as the date of the first dose and
o
only hour is missing the hour assigned is 12 or the hour of first dose, whichever is
later;
o
only the minute is missing the minute assigned is 30 or the minute of first dose,
whichever is later;
•

Efficacy variables include TETRAS-PS score, TETRAS-PS upper limb subscale score, 
TETRAS-PS upper limb tremor item 4 total score, Kinesia Upper Limb Tremor score,  
 Analyses of these data will be conducted on both the FAS and Per-Protocol 
Population within the same output for tables; figures will only be presented on the FAS. 
8.1. 
Primary Efficacy Analysis 
Not applicable. The primary analysis for this study is safety.  
8.2. 
Secondary Efficacy Analysis 
Normality assumptions of efficacy endpoints will be tested using the Anderson-Darling method. 
If the P value for the normality test is >0.05 the data will be considered normally distributed and 
will be analyzed as specified in subsequent sections. Otherwise, if the P value is ≤0.05 the data 
will be considered non-normal and the Wilcoxon signed rank test will be used to assess the 
within-subject changes. The estimates, CIs and P values will be displayed.  
8.2.1. TETRAS Performance Subscale Scores 
The TETRAS-PS Subscale (Version 3.1) score includes the following 9 items: head tremor, face 
(including jaw) tremor, voice tremor, upper limb tremor (left/right), lower limb tremor, 
Archimedes spirals, handwriting, dot approximation task, and standing tremor. Scores for each 
item range from 0 to 4 in increments of 0.5. Derivation for the TETRAS-PS Total score is 
described in Section 6.1.8. For lower limb tremor, only the maximum of the item 5 scores will be 
used. The TETRAS-PS assessments will be administered by a certified rater (referred to as a 
local rater hereafter) at Screening, Pre-dose, Day 1, Day 7, Day 14, and Day 21. The TETRAS-
PS assessments will also be recorded using videography for centralized evaluation and rating by 
independent blinded central raters (neurologists) with expertise in the assessment of ET. All 
scores (item scores and total scores) by both local and central raters will be analyzed in the same 
way as described below for central rater data. 
Observed values and change from baseline in each item score and in TETRAS-PS total score by 
central rater will be summarized overall, by cohort (see Section 6.1.2), and by study visit using 
descriptive statistics. 
Additionally, tests of hypotheses comparing mean and median TETRAS-PS total scores between 
baseline and subsequent study visits will be conducted using a 2-sided paired t-test or Wilcoxon 
signed rank test. The null hypothesis is that the change from baseline in TETRAS-PS total score 
to subsequent visit is 0 with a 2-sided alternative considering a difference not 0 (significant 
changes in tremor). 
As a supportive analysis, change from Screening to Baseline and change from Day 14 to Day 21 
in each item score and in TETRAS-PS total score will be summarized overall and by cohort (see 
Section 6.1.2) using descriptive statistics.

8.2.2. TETRAS Upper Limb Subscale Score 
Upper limb tremor is assessed during the following maneuvers: forward outstretched posture, 
lateral “wing beating” posture, kinetic (finger-chin-finger) testing, Archimedes spirals, 
handwriting, and dot approximation task. Each side of the body (right and left) is assessed and 
scored individually for all maneuvers except handwriting. The individual item question scores 
for each side of the body range from 0 to 4, with higher scores indicating more tremors. 
Derivation for the upper limb subscale score is described in Section 6.1.8. 
Assessments will be administered at Screening, Pre-dose, Day 1, Day 7, Day 14, and Day 21. 
Assessment results (scores) by local and central rater will be analyzed in the same way as 
described below for central rater score data. Observed values and change from baseline to all 
subsequent study visits in the upper limb subscale score will be summarized overall, by cohort 
(see Section 6.1.2), and by study visit using descriptive statistics.  
Additionally, tests of hypotheses comparing mean and median TETRAS-PS upper limb subscale 
scores between baseline and subsequent study visits will be conducted using a 2-sided paired t-
test and a Wilcoxon signed rank test, respectively. The null hypothesis is that the change from 
baseline in TETRAS-PS upper limb subscale score to subsequent visit is 0 with a 2-sided 
alternative considering a difference in either direction (i.e., change from baseline not equal to 0, 
representing significant change in tremor). 
As a supportive analysis, change from Screening to Baseline and change from Day 14 to Day 21 
in each item score and in TETRAS-PS upper limb subscale score will be summarized overall and 
by cohort (see Section 6.1.2) using descriptive statistics.

8.2.3. TETRAS-PS Upper Limb Tremor (Item 4) Total Score 
Item 4 of the TETRAS-PS represents upper limb tremor. Upper limb tremor is assessed during 
three maneuvers: forward outstretched posture, lateral “wing beating” posture, and kinetic 
(finger-chin-finger) testing. Each side of the body (right and left) is assessed and scored 
individually. The upper limb individual item score for each side of the body ranges from 0 to 4, 
with higher scores indicating more tremors. Derivation for the TETRAS-PS Upper Limb Tremor 
(Item 4) Total score is described in Section 6.1.8. 
Assessments will be administered at Screening, Pre-dose, Day 1, Day 7, Day 14, and Day 21. 
Assessment results (scores) by local and central rater will be analyzed in the same way as 
described below for central rater score data. Observed values and change from baseline to all 
subsequent study visits in the upper limb subscale score will be summarized overall, by cohort 
(see Section 6.1.2), and by study visit using descriptive statistics.  
Additionally, tests of hypotheses comparing mean and median TETRAS-PS Upper Limb Tremor 
(Item 4) Total scores between baseline and subsequent study visits will be conducted using a 2-
sided paired t-test and a Wilcoxon signed rank test, respectively. The null hypothesis is that the 
change from baseline in TETRAS-PS Upper Limb Tremor (Item 4) Total score to subsequent 
visit is 0 with a 2-sided alternative considering a difference in either direction (i.e., change from 
baseline not equal to 0, representing significant change in tremor).  
As a supportive analysis, change from Screening to Baseline and change from Day 14 to Day 21 
in each item score and in TETRAS-PS Upper Limb Tremor (Item 4) Total score will be 
summarized overall and by cohort (see Section 6.1.2) using descriptive statistics. 
A waterfall plot presenting mean change from baseline and 95% CI in TETRAS-PS Upper Limb 
Tremor (Item 4) Total Score by study visit will also be displayed. Additionally, a line graph of 
mean change from baseline and percent change from baseline will be displayed by study visit.

8.2.9. Wearable Sensor (Kinesia) 
In addition to the assessment of efficacy via rating scales, treatment effect will be evaluated by 
measuring tremor with a sensor worn on the upper limb (right and left index fingers). These 
assessments will be conducted during the clinic visits and optionally at-home. The motion sensor 
uses three orthogonal accelerometers and three orthogonal gyroscopes to monitor three-
dimensional motion. Data are then transmitted from the sensor to a computer using Bluetooth 
technology. These measures of three-dimensional motion for each maneuver are then converted 
to Kinesia scores. Each Kinesia score ranges from 0.0 to 4.0; higher scores indicate more severe 
tremor. 
The wearable sensor measurements of upper limb tremor assessments will be completed in the 
clinic once at any time during the Screening visit and at two different times during the Pre-dose 
clinic visit. During the clinic visit on Days 1, 7 and 14, the wearable sensor measurements of 
upper limb tremor will be captured once, 2 to 4 hours following the in-clinic dose. During the 
Follow-up visit (Day 21), the wearable sensor measurements of upper limb tremor will be

completed at any time during the visit. In-clinic assessments will be obtained during the 
performance of 4 maneuvers:  
1. extended arms posture,
2. wing-beating posture,
3. kinetic “finger-to-chin” movement, and
4. arm on table posture.
Two measurements at Pre-dose will be averaged and the means of 2 sets of measurements (mean 
of Kinesia score, mean amplitude, and mean frequency) will be used to represent Pre-dose 
values. 
These assessments will be performed twice, once with the sensor on the left index finger and 
once with the sensor on the right index finger.  
Observed values and change from baseline in the in-clinic wearable sensor measures of upper 
limb tremor severity, mean amplitude, and mean frequency will be summarized overall, by 
cohort (see Section 6.1.2), 
 and study visit using 
descriptive statistics. 
As a supportive analysis, change from Screening to Baseline and change from Day 14 to Day 21 
in the in-clinic wearable sensor measures of upper limb tremor severity, mean amplitude, and 
mean frequency for the above maneuvers will also be summarized. 
A waterfall plot presenting mean change from baseline and 95% CI in Wearable Sensor (Kinesia, 
in-clinic) measures by study visit will also be displayed.

Safety and Tolerability Analysis
The primary endpoint of the study is the occurrence and severity of TEAEs. 
Safety will be evaluated from reported AEs, serious AEs (SAEs), changes in clinical laboratory 
values, changes in vital signs, changes in orthostatic vital signs, 12-lead electrocardiograms 
(ECG), Columbia-Suicide Severity Rating Scale (C-SSRS), and physical and neurological 
examination results. 
All safety analyses will be performed on the Safety population. 
9.1. 
Adverse Events 
Any AE occurring after the date/time of informed consent signature but prior to the first dose of 
study medication (ie, occurring during the Screening and Baseline periods) will be listed. All 
AEs that occur after the first dose of study drug will be considered TEAEs. This includes any 
AEs that started or worsened (if present at baseline, increased in frequency or severity) after 
taking the first dose of the study drug. For AEs occurring on the date of first dose, if the time of 
onset is missing, the AE will be assumed to be treatment emergent. 
All AEs will be coded using the MedDRA Version 21.1 or higher coding dictionary.

The causal relationship of the AE to the study drug is determined by the investigator as Not 
Related, Unlikely Related, Possibly Related, Probably Related, and Definitely Related. These 
will be mapped to Unrelated (Not Related or Unlikely Related) and Related (Possibly Related, 
Probably Related, and Definitely Related).  
Adverse events severity grades are reported as mild, moderate, or severe. 
Summaries of incidence rates (frequencies and percentages) of individual TEAEs will be 
presented by SOC, PT, and cohort. Such summaries will be displayed for all TEAEs, TEAEs by 
maximum severity, and TEAEs by relationship.  
Each subject will be counted only once within each summation level (SOC and PT). If a subject 
experiences more than 1 TEAE within each summation level only the TEAE with the strongest 
relationship or the maximum severity, as appropriate, will be included in the summaries by 
subject for relationship and severity, respectively. If a particular event is missing the severity 
and/or relationship, then the strongest possible severity or relationship will be assumed for 
analysis (severity=severe, relationship = definitely related). 
Incidences will be presented by descending frequency of SOC and PT within SOC, and then 
alphabetically within PT where the incidence is the same. 
Missing and partially missing AE start and/or stop dates will be imputed, for the purpose of 
statistical analysis, according to the specifications described in Section 6.1.9. 
Numbers of AEs will also be presented in these AE summary tables. 
In the AE data listings, all AEs will be displayed. AEs that are treatment emergent will be 
flagged. 
9.1.1. Adverse Events Leading to Withdrawal 
A summary of incidence rates (frequencies and percentages) of TEAEs leading to withdrawal of 
study drug or study discontinuation, by SOC, PT, and cohort will be prepared for the Safety 
population.  
A data listing of AEs leading to withdrawal of study drug or study discontinuation will also be 
provided, displaying details of the event(s) captured on the CRF. 
9.1.2. Deaths and Serious Adverse Events 
Any deaths that occur during the study will be listed. 
SAEs will be listed and also tabulated by SOC, PT, and cohort. 
9.2. 
Clinical Laboratory Evaluations 
Screening and safety laboratory tests will be performed at Screening, Pre-dose, Day 1, Day 7, 
Day 14, and at follow-up on Day 21. All laboratory test results will be summarized descriptively 
by study visit for the Safety Population overall and by cohort as both observed values and change 
from baseline values for each parameter. Categorical urinalysis results will be summarized using 
frequencies by study visit and cohort. Levels of composite biomarker panel for renal tubular 
injury will also be summarized by study visit and listed.

definition of baseline. Clinically significant abnormal findings will be reported as AEs. 
Abnormal laboratory results will be listed. 
Pregnancy test results will be listed. 
9.3. 
Vital Signs 
Descriptive summaries of observed values and changes from baseline will be calculated for 
supine systolic blood pressure (SBP), standing SBP, supine diastolic blood pressure (DBP), 
standing DBP, supine heart rate (HR), standing HR, respiration rate, and oral temperature by 
study visit for the Safety Population overall and by cohort. Shifts from baseline for SBP, DBP, 
and HR values below, within, or above the normal range will be provided by study visit for the 
Safety Population overall and by cohort.  Vital sign parameters outside the normal range will be 
flagged in the listings. The mean change from baseline in each parameter will also be plotted by 
study visit. Abnormal vital signs are as follows: 
•
SBP >140 mmHg
•
SBP <90 mmHg
•
DBP >90 mmHg
•
DBP <60 mmHg
•
HR >100 bpm
•
HR <60 bpm

Respiration rate >20 breaths/min
•
Respiration rate <12 breaths/min
•
Oral temperature >99.1 ºF/37.2 ºC
•
Oral temperature <97.8 ºF/36.5 ºC
Orthostatic vital signs (blood pressure and heart rate) will also be summarized by position and 
study visit and by cohort. During the Pre-dose visit, baseline orthostatic vital signs will include 3 
separate measurements and the average of the 3 baseline orthostatic vital signs measurements 
will be used for comparison to all post-treatment measurements. The average HR, SBP, and DBP 
will be presented in the pre-dose baseline summaries and each of the individual measurements 
will be listed for that study visit.  
Orthostatic hypotension will be defined as a reduction in systolic blood pressure of 20 mmHg or 
more and/or a reduction in diastolic blood pressure of 10 mmHg or more, for the standing 
measurement compared to the supine or semi-supine measurement. The frequency and 
percentage of subjects with orthostatic hypotension will also be presented by cohort. Any 
confirmed orthostatic hypotension or clinically significant measurements that are associated with 
clinical symptoms will be recorded as AEs. Orthostatic vital signs parameters outside the ranges 
specified above will be flagged in the listings.

12-lead ECGs will be obtained at Screening, Pre-dose, Day 1, Day 7, Day 14, and Day 21.
Descriptive summaries will be presented for ECG measures of PR interval, RR interval, mean 
heart rate, QRS interval, QT interval, and QTcF interval. Corrected QTc intervals will be 
calculated using Fridericia’s correction formula. These summaries will be presented by study 
visit for the Safety Population overall and by cohort. The mean change from baseline (pre-dose) 
for each parameter will be plotted by study visit. Values outside the normal range will be flagged 
in the listings. 
The number and percentage of subjects with normal, abnormal but not clinically significant, and 
abnormal and clinically significant ECG results will be summarized for the Safety population by 
study visit. 
Additionally, QTcF data will be summarized by the following categories by study visit: 
•

9.5.1. Physical Examination 
A complete physical examination (PE) will include general observations; head, eyes, ears, nose, 
throat, and musculoskeletal. Physical examinations will be conducted at screening, Pre-dose, 
Day 1, Day 7, Day 14, and Day 21. All physical examination results will be listed. 
9.5.2. Neurological Examination 
Neurological examinations will include assessment of mental status, cranial nerves, motor, 
sensory, reflexes, coordination, and gait. Neurological examinations will be conducted at 
screening, Pre-dose, Day 7, Day 14, and Day 21. All results will be listed. 
9.5.3. Columbia Suicide Severity Rating Scale 
The C-SSRS is a questionnaire that prospectively assesses Suicidal Ideation and Suicidal 
Behavior. At the Pre-dose visit, the “baseline” version of the C-SSRS will be administered. This 
version assesses Suicidal Ideation and Suicidal Behavior during the subject’s lifetime and during 
the past 12 months. At the Day 14 and Day 21 visits (and the Early Termination visit for subjects 
withdrawing early), the “since last visit” version will be administered. 
Suicidality data collected on the C-SSRS will be listed for all subjects in the Safety Population.

Kidney safety Composite Measure Biomarker 
The following 6 kidney safety composite measure biomarkers were tested using urine sample: 
uCreatine (uCr), uClusterin (uCLU) , uCystatin-C (uCysC), uKidney Injury Molecule-1 (uKIM-
1), u N-Acetyl-beta-D-Glucosaminidase (uNAG), Neutrophil Gelatinase-Associated Lipocalin 
(uNGAL) and uOsteopontin (uOPN). Measured concentration is first normalized by dividing it 
by the concentration of uCR at the same timepoint. The fold change from baseline at a given 
timepoint is then calculated using the normalized concentration at a time point divided by the 
normalized concentration at baseline. For example, the normalized uCysC concentration at a 
given timepoint is calculated as the concentration of CysC at that timepoint divided by the 
concentration of uCr at the same timepoint. The uCysC fold change from baseline at a given 
timepoint is calculated as the normalized CysC concentration at a given timepoint divided by the 
normalized uCysC concentration at baseline. Similar calculations apply to other composite 
measures.

Planned Listing Descriptions 
The following are planned data and subject data listings for protocol number CAD1883-201. 
In general, one listing will be produced per CRF domain. All listings will be sorted by treatment, 
site, and subject number unless otherwise specified. All calculated variables will be included in 
the listings. 
In all listings a blank line will be placed between each subject. Within a data listing, if an item 
appears line after line (eg, repetition of subject number), then only the first occurrence will be 
displayed. 
In data listings, the information for one subject will be kept on one page if at all possible, rather 
than splitting a subject’s information across pages. If a subject's data are displayed on extended 
to another page, the subject number will be displayed again at the top of any subsequent pages

"Page x of x" should be aligned to the right. Page x of y is for individual TLF only, not for the entire table sets. For example
there are 2 pages for T14.1.1, then it will be Page 1 of 2 and Page 2 of 2 respectively.
•
Keep one space line only between TLF title and page headers
•
Keep "program path and name" on the left while align "Run Date: ..." to the right
•
Keep one more decimal place for SD than for mean
•
Add "Missing" category where missing value is available
•
keep under TLF abbreviations in alphabetical order
•
keep different footnotes separately in different lines.
•
For any conditions coded by SOC and PT, please sort the SOC by alphabetical order, and sort the PT under SOC by decreasing
frequency in the overall column, unless specified otherwise.

Note: Percentages are n/Number of subjects in the Safety Population*100. Subjects were to receive treatment twice daily for 14 consecutive days for a total of 28 doses. Compliance 
is number of doses taken / number of expected doses * 100%. Number of doses taken is calculated as the number of expected doses (number of capsules dispensed) minus total 
number of pills not taken minus number of unused capsules returned, as collected in the case report form. Expected doses are summed up to the point of discontinuation (eg, if a 
subject discontinues early, only planned doses up to that discontinuation day are counted in the denominator).

Subjects are classified according to the strongest relationship if the subject reported one or more events. Related TEAEs are those marked as Possibly Related, Probably Related, 
or Definitely Related on the CRF. AEs with a missing relationship will be considered related for this summary.  
AEs are displayed by descending frequency of SOC, then PT within SOC, and then alphabetically by PT.

Abbreviation: TEAE = treatment emergent adverse event. 
Note: Study day is calculated relative to the date of first dose. For pre-dose: study day= Start Date/ Stop Date – first dose date; For post-dose: study day= Start Date/ Stop Date – 
first dose date + 1. 
AEs were coded using MedDRA version 21.1.  
A TEAE is any AE that occurs after the time of treatment with the study agent. Events meeting this definition will be those events that are a change from the subject’s baseline 
conditions, including an increase in frequency or severity. 
Programming note: “Other Action Taken” will be either None, Medication Required, Relevant Procedure, or Other; if specify text is needed, concatenate “Relevant Procedure:” or 
“Other:” with the text. If Serious? Is Yes, concatenate all serious criteria marked as Yes with a semicolon. If no events meet the criteria for display, present “No events are reported.” 
SOC & PT text should be in proper case in table, as shown in the shell. Ensure correct MedDRA version is printed in footnote.

Abbreviations: AL = abnormal-low; AH = abnormal-high; CS = clinically significant; NCS = not clinically significant; ND = not done. 
Note: Study day is calculated relative to the date of first dose of study drug. For pre-dose: study day= Start Date/ Stop Date – first dose date; For post-dose: study day= Start Date/ Stop Date – first 
dose date + 1. 
If any parameter has an abnormal value, results for all study visits are presented. 
[1] Baseline is the last observation recorded prior to the first dose of treatment. 
[2] Reference range is used to identify potentially clinically significant laboratory values. 
 
Programming note: update abbreviations to reflect actual data. If test was not done, set results to ND; make sure last column is populated accordingly. Do not display serum HCG 
results in this listing. For reference range flag, concatenate AL or AH with clinical significance like “XX-YY” (eg, AL-CS).

the lifetime and more recent experience (past 12 months) of the subject with suicidal ideation and behavior, a baseline evaluation that focuses on suicidality since Screening that 
occurs before first dose of study drug (all of which is summarized under “pre-treatment”), and a post-baseline evaluation (“post-treatment”) administered at either Day 21 visit or 
early termination visit for discontinued subjects, which focuses on suicidality since the last study visit. Subjects are counted once for each C-SSRS section and once for each C-
SSRS item answered “Yes” in pre-treatment and post-treatment.

Abbreviation: TETRAS-PS = Tremor Research Group Essential Tremor Rating Assessment Scale Performance Subscale. 
Note: Study day is calculated relative to the date of first dose of study drug. For pre-dose: study day= Assessment Date – Date of the first dose of date; For post-dose: study day= 
Assessment Date – first dose date + 1.  
Each individual item question score ranges from 0 to 4, where higher scores indicate worse quality of life. 
TETRAS-PS Total score is derived as the sum of the 16 individual item scores (only the maximum of the item 5, lower limb tremor scores will be counted), with a maximum total 
score of 64.  
TETRAS-PS Upper Limb Subscale score is derived as the sum of the item 4, item 6, item 7 and item 8 scores (forward outstretched postural tremor, lateral “wing beating” postural 
tremor, kinetic tremor, Archimedes spirals, and dot approximation task from both sides of the body, as well as handwriting, with a maximum total score of 44.  
TETRAS-PS Upper Limb Tremor (Item 4) Total score is derived as the sum of the 6 item 4 scores (forward outstretched postural tremor, lateral “wing beating” postural tremor, and 
kinetic tremor scores) from both sides of the body, with a maximum total score of 24. 
Programming Note: If Assessment was not completed or videography was not uploaded to the portal, concatenate reason. CAD-1883 Administered In-Clinic will come from EX CRF, 
if date of in-clinic administration at the corresponding visit is not null. If not administered in clinic, concatenate reason not administered with a semicolon.

[1] Orthostatic hypotension is defined as a reduction in SBP of 20 mmHg or more, and/or a reduction in DBP of 10 mmHg or more, for the standing measurement compared
to the supine or semi-supine measurement.
Programming Note:  If measurements are not orthostatic, put ‘NA’ in the “Measurement Number/Was Measurement Performed?” and “Average” Columns. If a 
measurement is outside the normal range, place an asterisk (*) next to the value in the cell. 
Please use "Standing-Average", "Supine-Average" respectively for averaged values. "Standing-Supine" for difference.

Note: All subjects received CAD-1883 300 mg BID. At the Pre-dose visit, the “baseline” version of the C-SSRS was administered. This version assesses Suicidal Ideation and 
Suicidal Behavior during the subject’s lifetime and during a predefined period. At the Day 21 visit (and the Early Termination visit for subjects withdrawing early), the “since last visit” 
version was administered.  
Study day is calculated relative to the date of the first dose of study drug.
