Brief summary:
Phase 1, multicenter, open-label, 2-part, single- and multiple-dose study designed to assess the effect of hepatic insufficiency on the PK of aramchol

Detailed description:
Each of the 2 parts of the study consisted of a screening period, a check in day, a treatment period, and an end of study (EOS) visit.

In Part 1 (single-dose): 39 subjects were enrolled: 8 subjects each in the mild (Cohort A), moderate (Cohort B), and severe (Cohort C) hepatic impairment cohorts and 15 healthy control subjects with normal hepatic function (Cohort D). Enrollment of 8 subjects with mild hepatic impairment (Cohort A) proceeded only if there is evidence of reduced clearance of aramchol in Cohort B. Assignment to cohorts A to C, was according to Child Pugh classification system.

Serial blood samples for PK analysis of aramchol concentrations in plasma were collected before dosing (0 hour) and up to 168 hours for healthy subjects and 240 hours for hepatically impaired subjects after administration of aramchol.

In Part 2 (multiple-dose), a cohort of 4 subjects comprising of mild, 7 moderate , as well as a cohort of 7 healthy volunteers was administered with aramchol as multiple doses to obtain the PK profile of aramchol at steady state. Aramchol was given twice daily for 12 days. Trough blood samples for analysis of aramchol plasma concentrations was collected before the AM dose on several days and at intervals to 12 hours after the AM dose on Day 12.

PROTOCOL SYNOPSIS 
PROTOCOL NO.: Aramchol-019 
TITLE: A Phase 1, Open-Label Study to Evaluate the Safety, Tolerability, and 
Pharmacokinetics of Aramchol in Subjects With Hepatic Impairment 
STUDY PHASE: 1 
STUDY SITES: 3 clinical sites in the United States 
OBJECTIVES: 
The primary objective of this study is to compare the pharmacokinetic (PK) profile of 
aramchol administered orally in subjects with hepatic impairment with that of healthy 
subjects. 
The secondary objective of this study is to assess the safety and tolerability of aramchol 
administered orally in subjects with hepatic impairment. 
STUDY DESIGN: 
This is a Phase 1, multicenter, open-label, 2-part, single- and multiple-dose study designed to 
assess the effect of hepatic insufficiency on the PK of aramchol. 
Each part of the study will consist of a screening period, a check-in day, a treatment period, 
and an end-of-study (EOS) visit. 
In Part 1 (single-dose), up to 48 subjects are planned: 8 subjects each in the mild (Cohort A), 
moderate (Cohort B), and severe (Cohort C) hepatic impairment cohorts and 8 to 24 healthy 
control subjects with normal hepatic function (Cohort D). Enrollment of 8 subjects with mild 
hepatic impairment (Cohort A) will proceed only if there is evidence of reduced clearance of 
aramchol in Cohort B. At screening, subjects will be assigned to a study cohort according to 
the Child-Pugh classification system as follows: 
Cohort 
Hepatic Condition 
Child-Pugh Grade 
Number of Subjects 
A(a) 
Mild impairment 
Class A (Score of 5 to 6) 
8 
B 
Moderate impairment 
Class B (Score of 7 to 9) 
8 
C 
Severe impairment 
Class C (Score of 10 to 15) 
8  
D 
Healthy (control) 
— 
8 to 24 
(a) Enrollment of subjects into Cohort A will only proceed if there is evidence of reduced clearance of aramchol 
in Cohort B. 
Healthy control subjects (Cohort D) will be matched with hepatically impaired subjects 
(Cohorts A, B, and C) according to gender, age (±10 years), and body mass index (±20%). 
Safety data and PK profiles of aramchol from at least 4 subjects with moderate hepatic 
impairment (Cohort B) will be obtained and reviewed while enrollment to this cohort 
continues. These 4 subjects in Cohort B must demonstrate satisfactory safety (no serious 
adverse events [AEs] or severe AEs related to aramchol) and PK results for up to 4 days after 
dosing before enrollment of subjects with severe hepatic impairment (Cohort C) is initiated. 
Two subjects with severe hepatic impairment must demonstrate satisfactory safety and 
tolerability (no serious AEs or severe AEs related to aramchol) for up to 4 days after dosing 
before the remaining subjects with severe hepatic impairment may be dosed.

Enrollment of subjects into Cohort A (mild hepatic impairment) will proceed only if there is 
evidence of reduced clearance of aramchol in the first 4 subjects in Cohort B (moderate 
hepatic impairment), defined as a reduction in apparent total oral clearance (CL/F) of greater 
than 30% compared with values in historical healthy control subjects.  
In Part 2, a cohort of at least 8 subjects comprising of mild and moderate or moderate and 
severe hepatic impairment subjects will be administered aramchol as multiple doses to obtain 
the PK profile of aramchol at steady state. A decision on the severity of hepatic impairment 
of subjects to participate in Part 2 (multiple-dose) will be made by the sponsor based on the 
available safety and PK results from Part 1 (single-dose). 
Healthy control subjects will be matched with the hepatically impaired subjects according to 
gender, age (±10 years), and body mass index (±20%). 
Single Dose (Part 1): 
On Day 1, subjects will receive a single oral dose of 600 mg aramchol administered with 
water in the morning, after an overnight fast of at least 10 hours, and approximately 
30 minutes after consuming a standardized breakfast. Subjects will remain fasted except for 
water for 2 hours after dosing. During the study, subjects may consume water on an ad 
libitum basis. Hepatically impaired subjects will receive a diet standardized for hepatic 
impairment and healthy control subjects will receive a similar diet. 
Serial blood samples for PK analysis of aramchol concentrations in plasma will be collected 
before dosing (0 hour) and up to 168 hours for healthy subjects and 240 hours for hepatically 
impaired subjects after administration of aramchol. 
Subjects will be confined to the clinical site from Day –1 until discharge on Day 8 for healthy 
control subjects and on Day 11 for hepatically impaired subjects. The duration of the study, 
excluding screening, is approximately 23 days. 
Multiple Dose (Part 2): 
Multiple dosing will involve twice daily (approximately 12 hours apart) oral administration 
of aramchol for 11 days with a single AM dose on Day 12 to achieve steady state. The dosage 
will not exceed 300 mg twice daily but may be adjusted to give lower exposure depending on 
review of available data on any reduction in clearance associated with hepatic impairment 
seen with single doses in Part 1. Subjects will consume a standardized meal 30 minutes prior 
to the AM and PM doses of aramchol. Subjects will remain fasted except for water for 
2 hours after dosing. During the study, subjects may consume water on an ad libitum basis. 
Hepatically impaired subjects will receive a diet standardized for hepatic impairment and 
healthy control subjects will receive a similar diet. 
Blood samples for analysis of aramchol concentrations in plasma will be collected before the 
AM dose on Days 1, 4, 8, 9, 10, 11, and 12 and at intervals to 12 hours after the AM dose on 
Day 12. Samples of plasma will also be stored for analysis of metabolites pending results of a 
mass balance study.

STUDY TREATMENTS: 
Single Dose (Part 1): 
Aramchol will be administered as a single oral dose of 600 mg (2 × 300-mg tablets) in the 
morning on Day 1 with water approximately 30 minutes after a standardized breakfast. 
Multiple Dose (Part 2): 
Aramchol will be administered as an oral dose that will not exceed 300 mg twice daily 
(approximately 12 hours apart) for 11 days and a single AM dose on Day 12 with water 
approximately 30 minutes after a standardized meal. 
STUDY PROCEDURES: 
Pharmacokinetic Assessments and Endpoints: 
Single Dose (Part 1): 
Blood samples for analysis of concentrations of aramchol and its metabolites in plasma will 
be collected at the following time points: before dosing (0 hour) and at 1, 2, 3, 4, 5, 6, 8, 10, 
12, 14, 18, 24, 48, 72, 96, 120, 144, 168, 192, and 240 hours (the last 2 time points are for 
hepatically impaired subjects only) after administration of aramchol. 
The following plasma PK parameters will be calculated as endpoints for aramchol using 
actual sampling times rather than scheduled sampling times: 
• Area under the plasma concentration versus time curve (AUC) from time 0 to the last 
quantifiable concentration (AUC0-t) 
• AUC from time 0 extrapolated to infinity (AUC0-inf) 
• Maximum observed plasma concentration (Cmax) 
• Time to reach maximum observed plasma concentration (Tmax) 
• Time to the first measurable plasma concentration (Tlag) 
• Apparent terminal elimination half-life (t1/2) 
• Apparent oral clearance (CL/F) 
• Apparent volume of distribution (Vz/F) 
• Elimination rate constant (ke) 
Multiple Dose (Part 2): 
Blood samples for analysis of concentrations of aramchol and its metabolites in plasma will 
be collected before the AM dose on Days 1, 4, 8, 9. 10, 11, and 12 and at the following times 
after the AM dose on Day 12: 1, 2, 3, 4, 5, 6, 8, 10, and 12 hours. 
The following plasma PK parameters on Day 12 will be calculated as endpoints for aramchol 
using actual sampling times rather than scheduled sampling times (if conducted): 
• AUC from time 0 to the dosing interval tau at steady state (AUC0-tau, ss) 


Galmed Research and Development Ltd

Clinical Study Protocol 
 
 
Page 13 
• Maximum observed plasma concentration at steady state (Cmax, ss) 
• Time to reach maximum observed plasma concentration at steady state (Tmax, ss) 
• Minimum observed plasma concentration at steady state (Cmin, ss) 
• Time of minimum observed plasma concentration at steady state (Tmin, ss) 
• Average plasma concentration at steady state (Cavg, ss) 
Time to reach steady state will also be estimated graphically by assessing trough plasma 
concentrations (ie, pre-AM dosing on Days 1, 4, 8, 9, 10, 11, and 12) over 12 days of 
administration. 
Safety Assessments and Endpoints: 
Safety and tolerability will be assessed by the following endpoints: monitoring and recording 
of AEs, clinical laboratory test results (hematology, coagulation, serum chemistry, and 
urinalysis), vital sign measurements, 12-lead ECG results, and physical examination findings. 
STATISTICAL ANALYSIS PLANS: 
Sample Size: 
For Part 1, up to 48 subjects are planned: 8 subjects each in the mild (Cohort A), moderate 
(Cohort B), and severe (Cohort C) hepatic impairment groups, and 8 to 24 healthy control 
subjects with normal hepatic function (Cohort D). For Part 2, at least 8 subjects with mild 
and moderate or moderate and severe hepatic impairment and up to 8 healthy control subjects 
with normal hepatic function are planned. The sample size was chosen for this study based 
on clinical and practical considerations and not on a formal statistical power calculation. The 
US Food and Drug Administration Guidance for Industry, Pharmacokinetics in Patients With 
Impaired Hepatic Function: Study Design, Data Analysis, and Impact on Dosing and 
Labeling, was used as a guide to select the sample size, which is considered sufficient to 
adequately assess the safety and PK profiles of aramchol. 
In the event of early withdrawals or discontinuations, subjects may be replaced at the 
discretion of the investigator, and after consultation with the medical monitor and sponsor if 
the number of completers will be less than 6 subjects in any cohort. 
Analysis Sets: 
The PK population will include subjects who receive at least 1 dose of aramchol and have 
sufficient concentration data to support accurate estimation of at least 1 PK parameter. In 
Part 1, subjects who experience vomiting within 6 hours after dosing will be excluded from 
the PK analysis. 
The safety population will include all subjects who receive at least 1 dose of aramchol. 
Pharmacokinetic Analyses: 
Plasma concentrations will be listed and summarized descriptively (number of subjects, 
arithmetic mean, standard deviation [SD], coefficient of variation [CV], minimum, median, 
and maximum). Plasma concentration versus actual time profiles for each subject will be 
presented graphically. The mean plasma concentration versus scheduled time profiles will be 
presented graphically.

Pharmacokinetic parameters derived from plasma concentration data using 
noncompartmental methods will be summarized by hepatic group using descriptive statistics 
(number of subjects, arithmetic mean, SD, CV, minimum, median, and maximum). 
Geometric mean and geometric CV will also be calculated for AUCs and Cmax. The AUC0-t, 
AUC0-inf, and Cmax values may also be expressed in terms of unbound drug concentrations. 
An analysis of variance (ANOVA) model will be performed on the natural logarithms of 
AUC0-t, AUC0-inf, and Cmax to calculate the ratio of geometric means and its 90% confidence 
interval between subjects with hepatic impairment and the corresponding healthy control 
subjects, as appropriate. The ANOVA model will include hepatic group (normal matching 
mild, mild, normal matching moderate, moderate, normal matching severe, and severe, where 
applicable) as a fixed effect. 
For AUC0-t, AUC0-inf, and Cmax, a linear regression model will be performed on the natural 
logarithms of AUC0-t, AUC0-inf, and Cmax as dependent variables and each of the following 
natural-log-transformed hepatic function estimates as independent variables: Child-Pugh 
classification score (in subjects with hepatic impairment only), baseline serum bilirubin, 
serum albumin, and prothrombin time. The regression coefficients representing the 
relationship between the PK parameters and the hepatic function estimates will be estimated 
together with their 90% confidence intervals from the regression model. 
Sensitivity analyses may be conducted to investigate the potential impact of imbalance 
existing across hepatic impairment groups in the distribution of the baseline covariates used 
in subject matching (eg, body weight) and, if data suggest, appreciable differences in PK 
exposure (AUC0-t, AUC0-inf, and Cmax) across different values of the same baseline covariate.  
Detailed descriptions of the analyses in this study will be presented in the statistical analysis 
plan. 
Safety Analyses: 
Adverse events will be coded by preferred term and system organ class using the latest 
version of the Medical Dictionary for Regulatory Activities. All AE data will be presented in 
a data listing. Treatment-emergent AEs will be summarized by hepatic condition and overall, 
as well as by severity and relationship to study drug. Serious AEs and AEs leading to early 
discontinuation will also be presented in data listings. 
Actual values and changes from baseline for clinical laboratory test results, vital sign 
measurements, and 12-lead ECG results will be summarized by hepatic condition at each 
time point using descriptive statistics (number of subjects, mean, SD, minimum, median, and 
maximum). Shift tables will be generated for clinical laboratory test results. Clinical 
laboratory test results, vital sign measurements, 12-lead ECG results, and physical 
examination findings will be presented in data listings.

INTRODUCTION 
1.1 
BACKGROUND 
Aramchol is a novel conjugate of cholic acid (bile acid) and arachidic acid (saturated fatty 
acid), linked by a stable amide group. It is in development for treatment of nonalcoholic 
steatohepatitis (NASH) and fibrosis. Aramchol affects stearoyl coenzyme A desaturase 1, a 
key liver enzyme involved in regulating lipid metabolism. In animal models of NASH, it 
reduces steatosis, ballooning, inflammation, and fibrosis by down-regulation of stearoyl 
coenzyme A desaturase 1 expression in hepatocytes and hepatic stellate cells. 
Aramchol is highly lipophilic and pharmacokinetic (PK) studies in humans show that plasma 
concentrations increase less than proportionally to dose due to poor absorption. Its mean 
terminal phase half-life (t1/2) is approximately 3 days but most of the drug is cleared with a 
t1/2 of about 35 hours and steady state on repeat dosing is achieved within 7 to 10 days. 
Aramchol is secreted in bile and is excreted in feces. 
 
 
 
 
 
 
 
 Two 
Phase 2 clinical studies have been completed including a placebo-controlled study in which 
subjects with NASH were treated for 52-weeks. Significantly more subjects who received 
aramchol 600 mg daily showed NASH resolution without worsening of fibrosis and a larger 
proportion of subjects showed at least a 1-point improvement in fibrosis score without 
worsening of steatohepatitis. 
 
 
 
1.2 
RATIONALE FOR STUDY 
This study will compare the effect of varying degrees of hepatic impairment on the PK, 
safety, and tolerability of a single oral dose of 600 mg (2 × 300-mg tablets) aramchol in 


Galmed Research and Development Ltd 
Aramchol

Page 16 
Part 1 and multiple oral doses not to exceed 300 mg twice daily for 11 days and a single 
300 mg AM dose on Day 12 in Part 2 with healthy subjects. 
Hepatic impairment associated with cirrhosis may develop in subjects with NASH. 
Therefore, it is important to assess the effect of hepatic impairment on the PK and hence 
dosage requirements and safety of aramchol. 
1.3 
RATIONALE FOR DOSE SELECTION 
A single oral dose of 600 mg aramchol in Part 1 and multiple oral doses not to exceed 
300 mg aramchol twice daily for 11 days and a single AM dose on Day 12 in Part 2 will be 
evaluated in this study based on the recommendations provided in the US Food and Drug 
Administration (FDA) Guidance for Industry, Pharmacokinetics in Patients with Impaired 
Hepatic Function: Study Design, Data Analysis, and Impact on Dosing and Labeling 
(DHHS 2003). Though single doses up to 900 mg have been studied in healthy subjects and 
tolerated well, the single dose of 600 mg represents the highest dose likely to be used and 
was the daily dose administered in the Phase 2b study. The multiple dose of 300 mg twice 
daily has been well tolerated by healthy subjects for 10 days and is the dose to be taken daily 
by subjects participating in a Phase 3 clinical trial. 
The duration of multiple dosing is based on the apparent plasma elimination half-life of about 
35 hours and time taken to reach steady state of about 7 days in healthy subjects. A duration 
of 10 days was chosen to ensure steady state has been achieved by all the healthy subjects 
and an additional 2 days is considered appropriate for subjects with hepatic impairment 
owing to the possibility of reduced clearance in this population.

STUDY OBJECTIVES 
2.1 
PRIMARY OBJECTIVE 
The primary objective of this study is to compare the PK profile of aramchol administered 
orally in subjects with hepatic impairment with that of healthy subjects. 
2.2 
SECONDARY OBJECTIVE 
The secondary objective of this study is to assess the safety and tolerability of aramchol 
administered orally in subjects with hepatic impairment.

STUDY DESIGN 
This is a Phase 1, multicenter, open-label, 2-part, single- and multiple-dose study designed to 
assess the effect of hepatic insufficiency on the PK of aramchol. 
Each part of the study will consist of a screening period, a check-in day, a treatment period, 
and an end-of-study (EOS) visit. 
In Part 1 (single-dose), up to 48 subjects are planned: 8 subjects each in the mild (Cohort A), 
moderate (Cohort B), and severe (Cohort C) hepatic impairment cohorts and 8 to 24 healthy 
control subjects with normal hepatic function (Cohort D). Enrollment of 8 subjects with mild 
hepatic impairment (Cohort A) will proceed only if there is evidence of reduced clearance of 
aramchol in Cohort B. At screening, subjects will be assigned to a study cohort according to 
the Child-Pugh classification system as follows: 
Cohort 
Hepatic Condition 
Child-Pugh Grade 
Number of Subjects 
A(a) 
Mild impairment 
Class A (Score of 5 to 6) 
8 
B 
Moderate impairment 
Class B (Score of 7 to 9) 
8 
C 
Severe impairment 
Class C (Score of 10 to 15) 
8  
D 
Healthy (control) 
— 
8 to 24 
(a) Enrollment of subjects into Cohort A will only proceed if there is evidence of reduced clearance of aramchol 
in Cohort B. 
Healthy control subjects (Cohort D) will be matched with hepatically impaired subjects 
(Cohorts A, B, and C) according to gender, age (±10 years), and body mass index (BMI) 
(±20%). 
Safety data and PK profiles of aramchol from at least 4 subjects with moderate hepatic 
impairment (Cohort B) will be obtained and reviewed while enrollment to this cohort 
continues. These 4 subjects in Cohort B must demonstrate satisfactory safety (no serious AEs 
[SAEs] or severe AEs related to aramchol) and PK results for up to 4 days after dosing before 
enrollment of subjects with severe hepatic impairment (Cohort C) is initiated. Two subjects 
with severe hepatic impairment must demonstrate satisfactory safety and tolerability (no 
SAEs or severe AEs related to aramchol) for up to 4 days after dosing before the remaining 
subjects with severe hepatic impairment may be dosed. 
Enrollment of subjects to Cohort A (mild hepatic impairment) will proceed only if there is 
evidence of reduced clearance of aramchol in the first 4 subjects in Cohort B (moderate 
hepatic impairment), defined as a reduction in apparent total oral clearance (CL/F) of greater 
than 30% compared with values in historical healthy control subjects.

Page 18 
In Part 2, a cohort of at least 8 subjects comprising of mild and moderate or moderate and 
severe hepatic impairment subjects will be administered aramchol as multiple doses to obtain 
the PK profile of aramchol at steady state. A decision on the severity of hepatic impairment 
of subjects to participate in Part 2 (multiple-dose) will be made by the sponsor based on the 
available safety and PK results from Part 1 (single-dose). 
Healthy control subjects will be matched with the hepatically impaired subjects according to 
gender, age (±10 years), and BMI (±20%). 
Single Dose (Part 1): 
On Day 1, subjects will receive a single oral dose of 600 mg aramchol administered with 
240 mL of water in the morning, after an overnight fast of at least 10 hours, and 
approximately 30 minutes after consuming a standardized breakfast. Subjects will remain 
fasted except for water for 2 hours after dosing. During the study, subjects may consume 
water on an ad libitum basis. Hepatically impaired subjects will receive a diet standardized 
for hepatic impairment and healthy control subjects will receive a similar diet. 
Serial blood samples for PK analysis of aramchol concentrations in plasma will be collected 
before dosing (0 hour) and up to 168 hours for healthy subjects and 240 hours for hepatically 
impaired subjects after administration of aramchol. 
Subjects will be confined to the clinical site from Day –1 until discharge on Day 8 for healthy 
control subjects and on Day 11 for hepatically impaired subjects. The duration of the study, 
excluding screening, is approximately 23 days. 
Multiple Dose (Part 2): 
Multiple dosing will involve twice daily (approximately 12 hours apart) oral administration 
of aramchol for 11 days with a single AM dose on Day 12 to achieve steady state. The dosage 
will not exceed 300 mg twice daily but may be adjusted to give lower exposure depending on 
review of available data on any reduction in clearance associated with hepatic impairment 
seen with single doses in Part 1. Subjects will consume a standardized meal 30 minutes prior 
to the AM and PM doses of aramchol. Subjects will remain fasted except for water for 
2 hours after dosing. During the study, subjects may consume water on an ad libitum basis. 
Hepatically impaired subjects will receive a diet standardized for hepatic impairment and 
healthy control subjects will receive a similar diet. 
Blood samples for analysis of aramchol concentrations in plasma will be collected before the 
AM dose on Days 1, 4, 8, 9, 10, 11, and 12 and at intervals to 12 hours after the AM dose on

Day 12. Samples of plasma will also be stored for analysis of metabolites pending results of a 
mass balance study. 
Subjects will be confined to the clinical site from Day –1 until discharge on Day 13. The 
duration of the study, excluding screening, is approximately 28 days.

Page 29 
The investigator may withdraw a subject from the study if the subject: 
1. Is noncompliant with the protocol; 
2. Experiences an SAE or intolerable AE(s) that in the investigator’s opinion requires 
withdrawal from the study; 
3. Has laboratory safety assessments that reveal clinically significant hematological or 
biochemical changes from baseline values; 
4. Develops, during the course of the study, symptoms or conditions listed in the exclusion 
criteria; 
5. Requires a medication prohibited by the protocol; or 
6. Requests an early discontinuation for any reason. 
The investigator can also withdraw a subject upon the request of the sponsor, or if the 
sponsor terminates the study. Upon occurrence of an intolerable SAE or intolerable AE, the 
investigator will confer with the sponsor. If a subject is discontinued because of an AE, the 
event will be followed until it is resolved, stable, or judged by the investigator to be not 
clinically significant. 
4.4.2 
Handling of Withdrawals 
Subjects are free to withdraw from the study at any time upon request. Subject participation 
in the study may be stopped at any time at the discretion of the investigator or at the request 
of the sponsor. 
When a subject withdraws from the study, the reason(s) for withdrawal shall be recorded by 
the investigator on the relevant page in the electronic case report form (eCRF). Whenever 
possible, any subject who withdraws from the study prematurely will undergo all EOS 
assessments. Any subject who fails to return for final assessments will be contacted by the 
site in an attempt to have them comply with the protocol. The status of subjects who fail to 
complete final assessments will be documented in the eCRF.

4.4.3 
Replacements 
At the discretion of the investigator, and after consultation with the medical monitor and 
sponsor, any subject who withdraws before completing the study may be replaced to retain 
the target of 6 evaluable subjects based on clinical considerations. Any replacement subject 
will be assigned to receive the same treatment as the subject he or she is replacing. 
5. 
STUDY TREATMENTS 
5.1 
TREATMENTS ADMINISTERED 
All doses of study drug will be administered by mouth with 240 mL of room temperature 
water. During the study, subjects may consume water on an ad libitum basis. 
Hepatically impaired subjects will receive a diet standardized for hepatic impairment and 
healthy control subjects will receive a similar diet. Subjects should receive these meals at the 
same time during each part of the study. 
Single Dose (Part 1): 
On Day 1, all subjects will receive a single oral dose of 600 mg (2 × 300-mg tablets) 
aramchol in the morning, after an overnight fast of at least 10 hours and approximately 
30 minutes after a standardized breakfast. 
Multiple Dose (Part 2): 
Starting on Day 1, all subjects will receive an oral dose of aramchol that will not exceed 
300 mg twice daily (approximately 12 hours apart) for 11 days and a single AM dose on 
Day 12 approximately 30 minutes after a standardized meal. The dose may be adjusted to 
give lower exposure depending on the review of available data on any reduction in clearance 
associated with hepatic impairment seen with single doses in Part 1. 
5.2 
INVESTIGATIONAL PRODUCTS 
Aramchol will be supplied as 300-mg tablets.

5.2.1 
Study Drug Packaging and Storage 
The sponsor will provide the investigator and clinical site with adequate quantities of 
aramchol. The clinical site pharmacy will prepare the study treatments for each subject 
according to the schedule of events for Parts 1 and 2 (Section 3.1 and Section 3.2, 
respectively). 
All study drugs must be stored according to the labeled instructions in a secure cabinet or 
room with access restricted to necessary site personnel. The site will be required to keep a 
temperature log to establish a record of compliance with storage conditions. 
5.2.2 
Study Drug Accountability 
The investigator will maintain accurate records of receipt of all study drugs, including dates 
of receipt. Accurate records will be kept regarding when and how much study drug is 
dispensed and used by each subject in the study. Reasons for departure from the expected 
dispensing regimen must also be recorded. At the completion of the study, and to satisfy 
regulatory requirements regarding drug accountability, all study drugs will be reconciled and 
retained or, with approval of the sponsor, destroyed according to applicable regulations. 
5.3 
METHOD OF ASSIGNING SUBJECTS TO TREATMENT 
GROUPS 
This is a nonrandomized study. At screening, hepatically impaired subjects will be assigned 
to a study group based on their level of hepatic function according to the Child-Pugh 
classification system, as shown in Table 5–1. To allocate subjects to the appropriate cohort of 
hepatic impairment severity, a history of higher severity that has responded to medication 
will be taken into account. Thus, subjects with a history of Grade 3 or 4 encephalopathy that 
have responded to treatment with medicines such as lactulose or neomycin may be included 
with the subject receiving the point score for Grade 3 or 4 encephalopathy. Similarly, subjects 
with a history of moderate or severe ascites that have responded to diuretics may be included 
with the subject receiving the higher score.

on the sum of these points as follows: Child-Pugh Class A or mild hepatic impairment if the sum is 5 or 
6 points; Child-Pugh Class B or moderate hepatic impairment if the sum is 7 to 9 points; and Child-Pugh 
Class C or severe hepatic impairment if the sum is 10 to 15 points. 
(b) Grade 0: normal consciousness, personality, neurological examination, electroencephalogram. 
Grade 1: restless, sleep disturbed, irritable/agitated, tremor, impaired handwriting, 5 count-per-second 
waves. 
Grade 2: lethargic, time-disoriented, inappropriate, asterixis, ataxia, slow triphasic waves. 
Grade 3: somnolent, stuporous, place-disoriented, hyperactive reflexes, rigidity, slower waves. 
Grade 4: unarousable coma, no personality/behavior, decerebrate, slow 2-3 count-per-second delta activity. 
Hepatically impaired subjects (Cohorts A, B, and C) will be enrolled as they become eligible 
and receive their allocated subject numbers in the order in which they are enrolled into their 
respective cohorts.

BLINDING 
This is an open-label study. 
5.5 
TREATMENT COMPLIANCE 
All doses of the study drug will be administered in the clinical site under direct observation 
of site personnel and recorded in the eCRF. Clinic personnel will confirm that the subject has 
received the entire dose of study drug. 
The date and time of study drug dosing will be recorded on the appropriate page in the eCRF. 
If a subject is not administered study drug, the reason for the missed dose will be recorded. 
5.5.1 
Prior and Concomitant Medications 
Restrictions for prior and concomitant medications and therapies are provided in Section 4.1 
and Section 4.2. Prior and concomitant medications and therapies will be coded using the 
latest version of the World Health Organization Drug Dictionary available at initiation of the 
study.

5.5.1.1 
Prior Medications 
Information regarding prior medications taken by the subject within the 30 days before 
signing the informed consent form (ICF) will be recorded in the subject’s eCRF. 
5.5.1.2 
Concomitant Medications 
Any concomitant medication deemed necessary for the welfare of the subject during the 
study may be given at the discretion of the investigator. If a concomitant medication is taken, 
a joint decision will be made by the investigator and the sponsor to continue or discontinue 
the subject based on the time the medication was administered, its pharmacology and PK, 
and whether the use of the medication will compromise the safety of the subject or the 
interpretation of the data. The investigator is responsible for ensuring that details regarding 
the medication are adequately recorded in the eCRF. 
6. 
STUDY PROCEDURES 
Before performing any study procedures, all potential subjects will sign an ICF as outlined in 
Section 9.2.2.3. Subjects will undergo study procedures at the time points specified in the 
schedule of events for Parts 1 and 2 (Section 3.1 and Section 3.2, respectively). 
The total amount of blood collected from each subject over the duration of the study, 
including any extra assessments that may be required, will not exceed 500 mL. 
6.1 
PHARMACOKINETIC ASSESSMENTS AND ENDPOINTS 
Single Dose (Part 1): 
Blood samples for analysis of concentrations of aramchol and its metabolites in plasma will 
be collected at the following time points: before dosing (0 hour) and at 1, 2, 3, 4, 5, 6, 8, 10, 
12, 14, 18, 24, 48, 72, 96, 120, 144, 168, 192, and 240 hours (the last 2 time points are for 
hepatically impaired subjects only) after administration of aramchol. Acceptable time 
deviations are ±5 minutes for 0 to 4 hours, ±10 minutes for >4 to 8 hours, ±15 minutes for 
>8 to 24 hours, ±30 minutes for >24 to 72 hours, and ±60 minutes for >72 hours to 
240 hours. 
The following plasma PK parameters will be calculated as endpoints for aramchol using 
actual sampling times rather than scheduled sampling times: 
• AUC from time 0 to the last quantifiable concentration (AUC0-t) 


Galmed Research and Development Ltd 
Aramchol 
Protocol No. Aramchol-019 
Clinical Study Protocol 
 
 
Page 34 
• AUC from time 0 extrapolated to infinity (AUC0-inf) 
• Maximum observed plasma concentration (Cmax) 
• Time to reach maximum observed plasma concentration (Tmax) 
• Time to the first measurable plasma concentration (Tlag) 
• Apparent terminal elimination half-life (t1/2) 
• Apparent oral clearance (CL/F) 
• Apparent volume of distribution (Vz/F) 
• Elimination rate constant (ke) 
Multiple Dose (Part 2): 
Blood samples for analysis of concentrations of aramchol and its metabolites in plasma will 
be collected before the AM dose on Days 1, 4, 8, 9, 10, 11, and 12 and at the following times 
after the AM dose on Day 12: 1, 2, 3, 4, 5, 6, 8, 10, and 12 hours. Acceptable time deviations 
are ±5 minutes for 0 to 4 hours, ±10 minutes for >4 to 8 hours, and ±15 minutes for >8 to 
12 hours. 
The following plasma PK parameters on Day 12 will be calculated as endpoints for aramchol 
using actual sampling times rather than scheduled sampling times (if conducted): 
• AUC from time 0 to the dosing interval tau at steady state (AUC0-tau, ss) 
• Maximum observed plasma concentration at steady state (Cmax, ss) 
• Time to reach maximum observed plasma concentration at steady state (Tmax, ss) 
• Minimum observed plasma concentration at steady state (Cmin, ss) 
• Time of minimum observed plasma concentration at steady state (Tmin, ss) 
• Average plasma concentration at steady state (Cavg, ss) 
Time to reach steady state will also be estimated graphically by assessing trough plasma 
concentrations (ie, pre-AM dosing on Days 1, 4, 8, 9, 10, 11, and 12) over 12 days of 
administration.

Pharmacokinetic Sample Collection 
Details for the collection, processing, storage, and shipping of PK samples will be provided 
to the clinical site separately. 
6.1.2 
Pharmacokinetic Sample Analysis 
Pharmacokinetic samples will be analyzed using a validated liquid chromatography coupled 
with tandem mass spectrometry assay for aramchol in human plasma. Assay results and 
validation details will be provided in a separate bioanalytical report. Stored samples of 
plasma will also be analyzed for aramchol metabolites pending results of a mass balance 
study. 
6.2 
SAFETY ASSESSMENTS AND ENDPOINTS 
Safety and tolerability will be assessed by the following endpoints: monitoring and recording 
of AEs, clinical laboratory test results (hematology, coagulation, serum chemistry, and 
urinalysis), vital sign measurements, 12-lead ECG results, and physical examination findings. 
For all safety assessments, the investigator will determine whether results are clinically 
significant, which is defined as any variation in a result that has medical relevance and may 
result in an alteration in medical care (eg, active observation, diagnostic measures, or 
therapeutic measures). If clinical significance is noted, the result and reason for significance 
will be documented and an AE reported on the AE page in the subject’s eCRF. The 
investigator will monitor the subject until the result has reached the reference range or the 
result at screening, or until the investigator determines that follow-up is no longer medically 
necessary. 
6.2.1 
Adverse Events 
Adverse events will be assessed from the time the subject signs the ICF until EOS and should 
be followed until they are resolved, stable, or judged by the investigator to be not clinically 
significant. 
The investigator is responsible for ensuring that all AEs and SAEs are recorded in the eCRF 
and SAEs are reported to the sponsor, regardless of their relationship to study drug or clinical 
significance. If there is any doubt as to whether a clinical observation is an AE, the event 
should be reported.

6.2.1.1 
Adverse Event Definitions 
An AE is defined as any untoward medical occurrence associated with the use of a drug in 
humans, whether or not considered drug related. Subjects will be instructed to contact the 
investigator at any time after signing the ICF if any symptoms develop. 
A treatment-emergent AE is defined as any event not present before exposure to study drug 
or any event already present that worsens in intensity or frequency after exposure. 
A suspected adverse reaction is any AE for which there is a reasonable possibility that the 
study drug caused the AE. For the purposes of investigational new drug safety reporting, 
“reasonable possibility” means that there is evidence to suggest a causal relationship between 
the study drug and the AE. A suspected adverse reaction implies a lesser degree of certainty 
about causality than an adverse reaction. 
An adverse reaction is any AE caused by a study drug. Adverse reactions belong to a subset 
of all suspected adverse reactions and indicate that there are reasons to conclude that the 
study drug caused the event. 
An AE or suspected adverse reaction is considered “unexpected” if it is not listed in the 
investigator’s brochure or if it occurs with specificity or severity that has not been previously 
observed with the study drug being tested. 
An AE or suspected adverse reaction is considered an SAE/suspected unexpected serious 
adverse reaction if, in the view of either the investigator or sponsor, it results in any of the 
following outcomes: 
• Death 
• Life-threatening AE 
• Inpatient hospitalization or prolongation of existing hospitalization 
• Persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions 
• Congenital anomaly or birth defect 
Important medical events that may not result in death, be life threatening, or require 
hospitalization may be considered serious when, based upon appropriate medical judgment, 
they may jeopardize the subject and may require medical or surgical intervention to prevent

Clinical Study Protocol 
 
 
Page 37 
one of the outcomes listed in this definition. 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 hospitalization, or the development of 
drug dependency or drug abuse. 
An AE or suspected adverse reaction is considered “life threatening” if, in the view of either 
the investigator or sponsor, its occurrence places the subject at immediate risk of death. It 
does not include an AE or suspected adverse reaction that might have caused death if it had 
been more severe. 
6.2.1.2 
Eliciting and Documenting Adverse Events 
Subjects will be asked a standard question to elicit any medically related changes in their 
well-being. They will also be asked if they have been hospitalized, had any accidents, used 
any new medications, or changed concomitant medication regimens (both prescription and 
over-the-counter medications). 
In addition to subject observations, AEs will be documented from any data collected on the 
AE page in the eCRF (eg, laboratory values, physical examination findings, and ECG 
changes) or other documents that are relevant to subject safety. 
6.2.1.3 
Reporting Adverse Events 
All AEs reported or observed during the study will be recorded in the source documentation 
and on the AE page in the eCRF. Information to be collected includes drug treatment, type of 
event, time of onset, dosage, investigator-specified assessment of severity and relationship to 
study drug, time of resolution of the event, seriousness, any required treatment or 
evaluations, and outcome. Any AEs resulting from concurrent illnesses, reactions to 
concurrent illnesses, reactions to concurrent medications, or progression of disease states 
must also be reported. All AEs will be followed until they are resolved, stable, or judged by 
the investigator to be not clinically significant. The Medical Dictionary of Regulatory 
Activities will be used to code all AEs. 
Any medical condition that is present at the time that the subject is screened but does not 
deteriorate should not be reported as an AE but will be recorded as medical history. However, 
if it deteriorates at any time during the study, it should be recorded as an AE. 
Any AE that is considered serious by the investigator or that meets SAE criteria 
(Section 6.2.1.1) must be reported to the sponsor (or the sponsor’s designee) following the 


Galmed Research and Development Ltd 
Aramchol 
Protocol No. Aramchol-019 
Clinical Study Protocol 
 
 
Page 38 
guidelines provided on the study SAE form as soon as site personnel/investigator have 
become aware of the event and no later than 24 hours regardless of the relationship to the 
study drug. The investigator will assess whether there is a reasonable possibility that the 
study drug caused the SAE.  
Serious AE report form completion and reporting must not be delayed even when 
information is incomplete at the time of the initial report. Any additional (follow-up) 
information that becomes available after the initial reporting should be forwarded in a 
follow-up SAE report form by the site personnel within 24 hours of the information 
becoming available. 
All SAEs should be followed until resolution or stabilization of all parameters (including 
laboratory) return to baseline or until the investigator assesses them as stable or until the 
subject is lost to follow-up. 
The sponsor will be responsible for notifying the relevant regulatory authorities of any SAE 
as outlined in US Title 21 Code of Federal Regulations (CFR) Parts 312 and 320. The 
investigator is responsible for notifying the institutional review board (IRB) directly. 
For this study, the following contact information will be used for SAE reporting: 
6.2.1.4 
Assessment of Severity 
The severity (or intensity) of an AE refers to the extent to which it affects the subject’s daily 
activities and will be classified as mild, moderate, or severe using the following criteria: 
• Mild: These events require minimal or no treatment and do not interfere with the 
subject’s daily activities. 
• Moderate: These events result in a low level of inconvenience or require minor 
therapeutic measures. Moderate events may cause some interference with normal 
functioning. 
• Severe: These events interrupt a subject’s usual daily activity and may require systemic 
drug therapy or other treatment. Severe events are usually incapacitating. 
Changes in the severity of an AE should be documented to allow the duration of the event at 
each level of intensity to be assessed. An AE characterized as intermittent does not require 
documentation of the onset and duration of each episode.

Page 39 
6.2.1.5 
Assessment of Causality 
The investigator’s assessment of an AE’s relationship to study drug is part of the 
documentation process but is not a factor in determining what is or is not reported in the 
study. 
The investigator will assess causality (ie, whether there is a reasonable possibility that the 
study drug caused the event) for all AEs and SAEs. The relationship will be classified as 
follows: 
• Not related: There is not a reasonable possibility of relationship to study drug. The AE 
does not follow a reasonable temporal sequence from study drug administration or can be 
reasonably explained by the subject’s clinical state or other factors (eg, disease under 
study, concurrent diseases, and concomitant medications). 
• Related: There is a reasonable possibility of relationship to study drug. The AE follows a 
reasonable temporal sequence from study drug administration and cannot be reasonably 
explained by the subject’s clinical state or other factors (eg, disease under study, 
concurrent diseases, or concomitant medications), represents a known reaction to the 
study drug or other drugs in its class, is consistent with the known pharmacological 
properties of the study drug, and/or resolves with discontinuation of the study drug 
(and/or recurs with rechallenge, if applicable). 
6.2.1.6 
Follow-up of Adverse Events 
All AEs must be reported in detail on the appropriate page in the eCRF and followed until 
they are resolved, stable, or judged by the investigator to be not clinically significant. 
6.2.2 
Clinical Laboratory Testing 
Clinical laboratory tests will be performed by the clinical sites’ local laboratories. Blood and 
urine samples will be collected and prepared using standard procedures.  
Repeat clinical laboratory tests may be performed at the discretion of the investigator, if 
necessary, to evaluate inclusion and exclusion criteria or clinical laboratory abnormalities. 
The clinical laboratory that will perform the tests will provide the reference ranges for all 
clinical laboratory parameters. Abnormal clinical laboratory values will be flagged as either 
high or low (or normal or abnormal) based on the reference ranges for each laboratory 
parameter.

weight will be measured at check-in and EOS (or early termination). 
7. 
STATISTICAL ANALYSIS PLANS 
7.1 
SAMPLE SIZE CALCULATIONS 
For Part 1, up to 48 subjects are planned: 8 subjects each in the mild (Cohort A), moderate 
(Cohort B), and severe (Cohort C) hepatic impairment cohorts and 8 to 24 healthy control 
subjects with normal hepatic function (Cohort D). For Part 2, at least 8 subjects with mild 
and moderate or moderate and severe hepatic impairment and up to 8 healthy control subjects 
with normal hepatic function are planned. The sample size was chosen for this study based 
on clinical and practical considerations and not on a formal statistical power calculation. The 
US Food and Drug Administration Guidance for Industry, Pharmacokinetics in Patients With 
Impaired Hepatic Function: Study Design, Data Analysis, and Impact on Dosing and 
Labeling (DHHS 2003) was used as a guide to select the sample size, which is considered 
sufficient to adequately assess the safety and PK profiles of aramchol. 
In the event of early withdrawals or discontinuations, subjects may be replaced at the 
discretion of the investigator, and after consultation with the medical monitor and sponsor if 
the number of completers will be less than 6 subjects in any cohort. 
7.2 
ANALYSIS SETS 
The analysis populations are as follows: 
• The PK population will include subjects who receive at least 1 dose of aramchol and have 
sufficient concentration data to support accurate estimation of at least 1 PK parameter. In 


Galmed Research and Development Ltd 
Aramchol 
Protocol No. Aramchol-019 
Clinical Study Protocol 
 
 
Page 43 
Part 1, subjects who experience vomiting within 6 hours after study drug dosing will be 
excluded from the PK analysis. 
• The safety population will include all subjects who receive at least 1 dose of aramchol. 
7.3 
STATISTICAL ANALYSIS 
Details of all statistical analyses will be described in a statistical analysis plan. All data 
collected will be presented in data listings. Data from subjects excluded from an analysis 
population will be presented in the data listings but not included in the calculation of 
summary statistics. 
For categorical variables, frequencies and percentages will be presented. Continuous 
variables will be summarized using descriptive statistics (number of subjects, mean, standard 
deviation [SD], minimum, median, and maximum). 
Baseline demographic and background variables will be summarized by hepatic condition for 
all subjects. The number of subjects who enroll in the study and the number and percentage 
of subjects who complete the study will be presented. Frequency and percentage of subjects 
who withdraw or discontinue from the study, and the reason for withdrawal or 
discontinuation, will also be summarized. 
7.3.1 
Pharmacokinetic Analyses 
Plasma concentrations will be listed and summarized descriptively (number of subjects, 
arithmetic mean, SD, coefficient of variation [CV], minimum, median, and maximum). 
Plasma concentration versus actual time profiles for each subject will be presented 
graphically. The mean plasma concentration versus scheduled time profiles will be presented 
graphically. 
Pharmacokinetic parameters derived from plasma concentration data using 
noncompartmental methods with Phoenix® WinNonlin® (Certara USA Inc, Princeton, New 
Jersey) Version 8.0 or higher will be summarized by hepatic group using descriptive statistics 
(number of subjects, arithmetic mean, SD, CV, minimum, median, and maximum). 
Geometric mean and geometric CV will also be calculated for AUCs and Cmax. The AUC0-t, 
AUC0-inf, and Cmax values may also be expressed in terms of unbound drug concentrations. 
An analysis of variance (ANOVA) model will be performed on the natural logarithms of 
AUC0-t, AUC0-inf, and Cmax to calculate the ratio of geometric means and its 90% confidence 
interval between subjects with hepatic impairment and the corresponding healthy control 


Galmed Research and Development Ltd

Page 44 
subjects, as appropriate. The ANOVA model will include hepatic group (normal matching 
mild, mild, normal matching moderate, moderate, normal matching severe, and severe, where 
applicable) as a fixed effect. 
For AUC0-t, AUC0-inf, and Cmax, a linear regression model will be performed on the natural 
logarithms of AUC0-t, AUC0-inf, and Cmax as dependent variables and each of the following 
natural-log-transformed hepatic function estimates as independent variables: Child-Pugh 
classification score (in subjects with hepatic impairment only), baseline serum bilirubin, 
serum albumin, and prothrombin time. The regression coefficients representing the 
relationship between the PK parameters and the hepatic function estimates will be estimated 
together with their 90% confidence intervals from the regression model. 
Sensitivity analyses may be conducted to investigate the potential impact of imbalance 
existing across hepatic impairment groups in the distribution of the baseline covariates used 
in subject matching (eg, body weight) and, if data suggest, appreciable differences in PK 
exposure (AUC0-t, AUC0-inf, and Cmax) across different values of the same baseline covariate.  
Detailed descriptions of the analyses in this study will be presented in the statistical analysis 
plan. 
7.3.2 
Safety Analyses 
Adverse events will be coded by preferred term and system organ class using the latest 
version of the Medical Dictionary for Regulatory Activities. All AE data will be presented in 
a data listing. Treatment-emergent AEs will be summarized by hepatic condition and overall, 
as well as by severity and relationship to study drug. Serious AEs and AEs leading to early 
discontinuation will also be presented in data listings. 
Actual values and changes from baseline for clinical laboratory test results, vital sign 
measurements, and 12-lead ECG results will be summarized by hepatic condition at each 
time point using descriptive statistics (number of subjects, mean, SD, minimum, median, and 
maximum). Shift tables will be generated for clinical laboratory test results. Clinical 
laboratory test results, vital sign measurements, 12-lead ECG results, and physical 
examination findings will be presented in data listings. 
7.4 
HANDLING OF MISSING DATA 
Plasma concentrations that are below the limit of quantification (BLQ) will be treated as zero 
for descriptive statistics. Mean BLQ concentrations will be presented as BLQ, and the SD

Page 45 
and CV will be reported as not applicable. Missing concentrations will be excluded from the 
calculations. 
For the PK analysis, BLQ values will be treated as zero with the exception that a BLQ value 
between 2 quantifiable concentrations will be set as missing. Missing concentrations will be 
treated as missing from the PK parameter calculations. If consecutive BLQ concentrations 
are followed by quantifiable concentrations in the terminal phase, those concentrations after 
BLQ concentrations will be treated as missing. 
7.5 
INTERIM ANALYSES 
No formal interim analyses will be performed in this study.

APPENDIX 2: STUDY GOVERNANCE 
9.2.1 
Data Quality Assurance 
This study will be conducted using the quality processes described in applicable procedural 
documents. The quality management approach to be implemented will be documented and 
will comply with current International Council for Harmonisation (ICH) guidance on quality 
and risk management. All aspects of the study will be monitored for compliance with 
applicable government regulatory requirements, current Good Clinical Practice, the protocol, 
and standard operating procedures. The monitor will maintain current personal knowledge of 
the study through observation, review of study records and source documentation, and 
discussion of the conduct of the study with the investigator and staff. Electronic CRFs and 
electronic data capture will be utilized. The electronic data capture system is validated and 
compliant with US Title 21 CFR Part 11. Each person involved with the study will have an 
individual identification code and password that allows for record traceability. 
Important protocol deviations, should they occur during the study, will be presented in 
Section 10.2 of the clinical study report. 
9.2.2 
Investigator Obligations 
The following administrative items are meant to guide the investigator in the conduct of the 
study and may be subject to change based on industry and government standard operating 
procedures, working practice documents, or guidelines. Changes will be reported to the IRB 
but will not result in protocol amendments. 
9.2.2.1 
Confidentiality 
All laboratory specimens, evaluation forms, reports, and other records will be identified in a 
manner designed to maintain subject confidentiality. All records will be kept in a secure 
storage area with limited access. Clinical information will not be released without the written 
permission of the subject (or the subject’s legal guardian), except as necessary for monitoring 
and auditing by the sponsor, its designee, the FDA, or the IRB. 
The investigator and all employees and coworkers involved with this study may not disclose 
or use for any purpose other than performance of the study, any data, record, or other

9.2.2.2 
Institutional Review 
Federal regulations and ICH guidelines require that approval be obtained from an IRB before 
participation of human subjects in research studies. Before study onset, the protocol, ICF, 
advertisements to be used for the recruitment of study subjects, and any other written 
information regarding this study that is to be provided to the subject or the subject’s legal 
guardian must be approved by the IRB. Documentation of all IRB approvals and of the IRB 
compliance with the ICH harmonised tripartite guideline E6(R2): Good Clinical Practice will 
be maintained by the site and will be available for review by the sponsor or its designee. 
All IRB approvals should be signed by the IRB chairman or designee and must identify the 
IRB name and address, the clinical protocol by title or protocol number or both, and the date 
approval or a favorable opinion was granted. 
9.2.2.3 
Subject Consent 
Written informed consent in compliance with US Title 21 CFR Part 50 shall be obtained from 
each subject before he or she enters the study or before performing any unusual or nonroutine 
procedure that involves risk to the subject. If any institution-specific modifications to 
study-related procedures are proposed or made by the site, the consent should be reviewed by 
the sponsor or its designee or both before IRB submission. Once reviewed, the investigator 
will submit the ICF to the IRB for review and approval before the start of the study. If the 
ICF is revised during the course of the study, all active participating subjects must sign the 
revised form. 
Before recruitment and enrollment, each prospective subject or his/her legal guardian will be 
given a full explanation of the study and will be allowed to read the approved ICF. Once the 
investigator is assured that the subject/legal guardian understands the implications of 
participating in the study, the subject/legal guardian will be asked to give his or her consent 
to participate in the study by signing the ICF. A copy of the signed ICF will be provided to 
the subject/legal guardian. 
9.2.2.4 
Study Reporting Requirements 
By participating in this study, the investigator agrees to submit reports of SAEs according to 
the time line and method outlined in this protocol. In addition, the investigator agrees to

9.2.2.7 
Study Conduct 
The investigator agrees to perform all aspects of this study in accordance with the ethical 
principles that have their origin in the Declaration of Helsinki, ICH E6(R2): Good Clinical 
Practice; the protocol; and all national, state, and local laws or regulations. 
9.2.2.8 
Case Report Forms and Source Documents 
Site personnel will maintain source documentation, enter subject data into the eCRF as 
accurately as possible, and rapidly respond to any reported discrepancies. 
Electronic CRFs and electronic data capture will be utilized. The electronic data capture 
system is validated and compliant with US Title 21 CFR Part 11. Each person involved with 
the study will have an individual identification code and password that allows for record 
traceability. Thus, the system, and any subsequent investigative reviews, can identify 
coordinators, investigators, and individuals who have entered or modified records, as well as 
the time and date of any modifications. There may be an internal quality review audit of the 
data and additional reviews by the monitor. 
Each eCRF is presented as an electronic copy, allowing data entry by site personnel, who can 
add and edit data, add new subjects, identify and resolve discrepancies, and view records. 
This system provides immediate direct data transfer to the database, as well as immediate 
detection of discrepancies, enabling site coordinators to resolve and manage discrepancies in 
a timely manner. 
Paper copies of the eCRFs and other database reports may be printed and signed by the 
investigator. This system provides site personnel, monitors, and reviewers with access to 
hardcopy audits, discrepancy reviews, and investigator comment information. 
9.2.2.9 
Adherence to Protocol 
The investigator agrees to conduct the study as outlined in this protocol, in accordance with 
ICH E6(R2) and all applicable guidelines and regulations.

Study Management 
9.2.3.1 
Monitoring 
9.2.3.1.1 
Monitoring of the Study 
The monitor, as a representative of the sponsor, is obligated to follow the study closely. In 
doing so, the monitor will visit the investigator and clinical site at periodic intervals in 
addition to maintaining necessary telephone and email contact. The monitor will maintain 
current personal knowledge of the study through observation, review of study records 
including eCRFs and source documentation, and discussion of the conduct of the study with 
the investigator and staff. 
All aspects of the study will be carefully monitored by the sponsor or its designee for 
compliance with applicable government regulation with respect to current ICH E6(R2) 
guidelines and standard operating procedures. 
9.2.3.1.2 
Inspection of Records 
The investigator and institution involved in the study will permit study-related monitoring, 
audits, IRB review, and regulatory inspections by providing direct access to all study records. 
In the event of an audit, the investigator agrees to allow the sponsor, their representatives, the 
FDA, or other regulatory agencies access to all study records. 
The investigator should promptly notify the sponsor and clinical sites of any audits scheduled 
by any regulatory authorities and promptly forward copies of any audit reports received to 
the sponsor. 
9.2.3.2 
Management of Protocol Amendments and Deviations 
9.2.3.2.1 
Modification of the Protocol 
Any changes in this research activity, except those necessary to remove an apparent 
immediate hazard to the subject, must be reviewed and approved by the sponsor or designee. 
Amendments to the protocol must be submitted in writing to the investigator’s IRB for 
approval before subjects are enrolled into an amended protocol.

9.2.3.2.2 
Protocol Deviations 
The investigator or designee must document and explain in the subject’s source 
documentation any deviation from the approved protocol. The investigator may implement a 
deviation from, or a change to, the protocol to eliminate an immediate hazard to study 
subjects without prior IRB approval. As soon as possible after such an occurrence, the 
implemented deviation or change, the reasons for it, and any proposed protocol amendments 
should be submitted to the IRB for review and approval, to the sponsor for agreement, and to 
the regulatory authorities, if required. 
A protocol deviation is any change, divergence, or departure from the study design or 
procedures defined in the protocol. An important deviation (sometimes referred to as a major 
or significant deviation) is a subset of protocol deviations that leads to a subject being 
discontinued from the study, or significantly affects the subject’s rights, safety, or well-being 
and/or the completeness, accuracy, and reliability of the study data. An important deviation 
can include nonadherence to inclusion or exclusion criteria or nonadherence to FDA 
regulations or ICH E6(R2) guidelines. 
Protocol deviations will be documented by the monitor throughout the course of monitoring 
visits. Any additional protocol deviations that are found by the monitor during the course of 
monitoring visits will also be recorded by the monitor. The investigator will be notified in 
writing by the monitor of deviations. The IRB should be notified of all protocol deviations, if 
appropriate, in a timely manner. 
9.2.3.3 
Study Termination 
Although the sponsor has every intention of completing the study, they reserve the right to 
discontinue it at any time for clinical or administrative reasons. 
The end of the study is defined as the date on which the last subject completes the last visit 
(including the EOS visit). Any additional long-term follow-up that is required for monitoring 
of the resolution of an AE or finding may be appended to the clinical study report. 
9.2.3.4 
Final Report 
Regardless of whether the study is completed or prematurely terminated, the sponsor will 
ensure that clinical study reports are prepared and provided to the regulatory agency as 
required by the applicable regulatory requirement. The sponsor will also ensure that clinical 
study reports in marketing applications meet the standards of the ICH harmonised tripartite 
guideline E3: Structure and content of clinical study reports.
