Study Objectives 
Primary Objective: 
To assess the safety and tolerability of HM15912 after single subcutaneous 
(SC) doses 
Secondary Objective: 
To assess the PK profile of HM15912 after single SC doses 
Exploratory Objective: 
To explore the PD properties of HM15912 after single SC doses 
Study Design 
This is a double-blind, randomized, placebo-controlled, single ascending dose 
(SAD) study to assess the safety, tolerability, PK and PD of the SC 
administration of HM15912 in healthy Korean subjects. 
The study will be conducted in approximately 5 sequential dosing cohorts, 
enrolling 8 subjects per cohort. Subjects will be randomized to HM15912 or 
placebo in a ratio of 6:2 (6 active, 2 placebo). When necessary, one dosing 
cohort may be added or removed. 
In this first-in-human (FiH) study, each cohort will be divided in 2 blocks in 
order to implement the sentinel dosing approach. Within each cohort, the first 
block will consist of 2 sentinel subjects; 
1 subject will receive HM15912, and 1 subject will receive matched placebo. 
The second block will consist of 6 subjects randomized to receive HM15912 (n 
= 5) or matched placebo (n = 1). Individual subjects in the second block will be 
dosed at least 24 hours after the first block when safety and tolerability are 
found to be satisfactory by the Principal Investigator. 
Following an overnight fast of at least 10 hours, each subject will receive a single 
dose of either HM15912 or matched placebo-administered SC in the abdomen on 
the morning (8:00 AM - 10:00 AM) of Day 1. Subjects will continue fasting 
through approximately 4 hours postdose. Water intake is also limited for 
approximately 1 hour before dosing and approximately 2 hours after dosing. 
Water intake is also limited for approximately 1 hour before dosing and 
approximately 2 hours after dosing. 
The planned maximum dose of HM15912 is 1.5 mg/kg; however, higher doses 
may be administered if safety is confirmed in previous cohorts. If dose is 
escalated to 1.5 mg/kg or above, approval of the Ministry of Food and Drug 
Safety (MFDS) will be obtained. After at least 6 subjects (HM15912, n ≥ 4) in 
each cohort have completed assessments through at least Day 17, blinded safety 
data will be reviewed and a dose decision/dose escalation decision for the 

Hanmi Pharmaceutical Co., Ltd. 
HM-GLP2-101 
 
CONFIDENTIAL 
Final 4.2 
Page 6 of 75 
Apr 06, 2020 
subsequent cohort will be made by the Principal Investigator and the Sponsor. 
If there are PK/PD data obtained from the preceding or current cohorts, the 
PK/PD data will be reviewed as well when necessary. Escalation will only 
proceed if safety and tolerability data related to the dose of the prior cohort are 
verified. Determination of whether to proceed to the next cohort will be made 
by the Principal Investigator and the Sponsor, and changes in the dose and the 
number of cohorts will be approved by the MFDS and the IRB. 
PK data will only be reviewed if available. After review of the PK data from 
the preceding or current cohorts, changes in time points for PK collection, 
clinical laboratory assessments, and PD collection may be required and will be 
approved by the MFDS and the IRB. 
If dose escalation is stopped based on available blinded safety data, the current 
dose level will be considered as the minimum intolerable dose (MID). The dose 
just below the MID will be regarded as the maximum tolerated dose (MTD). If 
the dose escalation is stopped due to reaching exposure limit without dose-
limiting safety findings, the MTD cannot be determined. Dose de-escalation 
may occur in the last cohort or additional cohorts to further refine clinically 
relevant dose levels. 
The study will be comprised of: 
• A Screening visit up to 28 days before dosing 
• An inpatient assessment period of approximately 8 days, with admission to 
the institution on Day-1, dosing on Day 1, and discharge on Day 7 once the 
planned schedule is completed 
• Two Outpatient visits on Day 8 (± 4 hours), Day 10 (± 1 day), Day 17 (± 1 
day) and Day 30 (± 3 days) 
• A final Follow-up visit on Day 44 (± 3 days) 
The total duration of the clinical study per subject will be up to approximately 
72 days, including the Screening period. 
Investigational Product 
HM15912 and matching placebo will be supplied by the Sponsor as a sterile 
solution in prefilled syringes, manufactured by Hanmi Pharm. Co., Ltd. The 
concentration of HM15912 is 30 mg/mL as protein and the fill volume is 0.52 
mL including overfill. 
Doses will be administered via SC injection to subjects in approximately 5 dose 
cohorts. Additional cohorts may be enrolled and proceed at a dose higher or 
lower than the planned maximum dose of 1.5 mg/kg, if deemed appropriate by 
the Principal Investigator and the Sponsor, but cohorts are planned as follows:

cohorts will also be reviewed when necessary) will be reviewed and a dose 
decision/dose escalation decision for the subsequent cohort will be made by the 
Principal Investigator and the Sponsor. If dose escalation is stopped, dose de-escalation 
may occur in additional cohorts, to further refine clinically relevant dose levels. The 
planned maximum dose of HM15912 is 1.5 mg/kg; however, higher doses may be 
administered if safety is confirmed in previous cohorts. If dose is escalated to 1.5 mg/kg 
or above, MFDS approval will be obtained.

 General safety variables: Adverse event (AE) assessments, clinical 
laboratory tests (hematology, clinical chemistry, coagulation and urinalysis), 
vital signs (blood pressure [BP], pulse, tympanic temperature and 
respiratory rate [RR]), 12-lead electrocardiogram (ECG), physical 
examinations 
 Specific safety variables: Injection site assessments, immunogenicity 
assessments (ADA, NAb, anti-PEG) (performed only if analysis is 
necessary) 
Secondary Endpoints 
 Cmax: Maximum serum HM15912 concentration determined from the 
concentration-time profile 
 Tmax: Time of maximum serum HM15912 concentration determined from 
the concentration-time profile 
 AUC0-t: Area under the concentration-time curve from predose (time 0) to 
the last quantifiable concentration 
 AUCinf: Area under the concentration-time curve from predose (time 0) 
extrapolated to infinite time (AUC0-t + Clast/λz) calculated using the linear-
log trapezoidal rule 
 AUC%extrap: Percentage of AUCinf that is due to extrapolation beyond tlast  
 λz: The terminal elimination rate constant determined by selection of at least 
3 data points on the terminal phase of the concentration-time curve 
 t½: Terminal elimination half-life calculated as: ln2/λz  
 CL/F: Total body clearance calculated as: Dose/AUCinf 
 Vz/F: Apparent volume of distribution calculated as: Dose/(AUCinf * λz) 
Exploratory Endpoints 
 Blood plasma citrulline 
 Albumin, prealbumin 
 Fasting lipid panel (total cholesterol, triglycerides, low-density lipoprotein 
[LDL], high-density lipoprotein [HDL], very low-density lipoprotein 
[VLDL], free fatty acid [FFA]) 
 Blood glucose-related panel (fasting plasma glucose, gastric inhibitory 
polypeptide [GIP], glucagon-like peptide-1 [GLP-1], C-peptide, glucagon, 
insulin) 
 Insulin-like growth factor-1 (IGF-1) and keratinocyte growth factor (KGF) 
Statistical Methods 
Sample Size Considerations 
Enrolling 8 subjects per cohort (HM15912:placebo=6:2) has been set based on 
the experience and the general properties of exploratory studies, and this 
matches the typical sample size used in similar studies conducted to assess 
safety and PK. Therefore, no formal sample size calculation will be performed. 
Safety and tolerability of the IP will be assessed based on AEs, clinical 
laboratory parameters, physical examinations, vital signs and ECG parameters 
throughout the duration of the study. Safety analysis will involve examination 
of the descriptive statistics and individual subject listings for any effects of 
study treatment on clinical tolerability and safety.

ADA = anti-drug antibody; Anti-PEG = anti-polyethylene glycol; BMI = body mass index; BP = blood pressure; ECG = electrocardiogram; FFA = free fatty acid; FPG = fasting plasma glucose; 
FSH = follicle-stimulating hormone; GIP = gastric inhibitory polypeptide; GLP-1 = glucagon-like peptide-1; HDL = high-density lipoprotein; IP = investigational product; LDL = low-density 
lipoprotein; NAb = neutralizing antibody; PK = pharmacokinetics; RR = respiratory rate; SC = subcutaneous; VLDL = very low-density lipoprotein 
a. An additional Outpatient visit may be included in later cohorts, if required, after PK data are evaluated. If so, assessments scheduled on Day 17 will be performed at the additional Outpatient 
visit. 
b. If a subject is discontinued from the study or withdraws consent, the Principal Investigator must make every possible effort to perform the evaluations described for the Follow-up visit. 
Efforts will be made to perform the Follow-up visit within 30 days from the date the subject is discontinued from the study or withdraws consent. 
c. The criteria applicable for admission prior to randomization, i.e., exclusion criteria 1, 2, 3, 5, 6, 7, 8, 9, 10, 11, 13, 14, 15, 16, 17, 19, 20, 21, 22, 24, 25, 27, 28, 29, 30, and 31, will be 
checked again. 
d. Height will be measured only at the Screening visit. Height and weight measurements will be performed with shoes removed. Weight will be recorded rounded to 1 decimal place. If weight 
is measured rounded to 2 decimal places, the number is rounded off from the second digit after the decimal point. 
e. BMI will be calculated by the following formula: BMI = Weight (kg) ÷ ((Height (m) x Height (m)). The calculated BMI will be rounded to 1 decimal place. The height measured at the 
Screening visit will be used for BMI calculation, and if a value is calculated as 2 decimal places, the number is rounded off to the first place. 
f. Medical history which will be checked on Day-1 is limited to the medical history related to exclusion criteria 1, 2, 3, 6, 8, 9, 10, 11, 13, 14, 15, and 17. 
g. Serum pregnancy tests at the Screening visit and on Day-1; urine pregnancy tests at the Day 30/Follow-up visit.

h. HM15912 or placebo will be administered via SC injection into the abdomen on the morning of Day 1 after a minimum 10-hour fast. Subjects will continue fasting through approximately 4 
hours postdose. Water consumption will also be limited for 1 hour before dosing and for approximately 2 hours after dosing. After the planned 4-hour post-dose blood sampling (clinical 
laboratory tests and analysis of citrulline) and testing (12-lead ECG) are performed, subjects will be served lunch by the institution. 
i. Vital signs will be measured twice per day on Day 1 through Day 6 (AM and PM). Vital signs will be measured at predose and 6 hours postdose on Day 1. Vital signs will be measured 
whenever possible in the morning and afternoon between Day 2 and Day 6. All other assessments will be performed once per day whenever possible. BP and pulse will be measured for 2 
consecutive times after a subject has been lying down or sitting to rest ≥ 5 minutes, and mean values will be recorded. 
j. Samples for clinical laboratory tests will be collected after at least 12 hours of fasting. If the PK sampling time points are changed, the sampling times for clinical laboratory tests may be 
adjusted accordingly. 
k. 4, 48 and 72 hours postdose 
l. The 12-lead ECGs will be performed after a subject has been resting supine for ≥ 5 minutes. ECGs will be measured in triplicate in the morning during admission. Only for Day 1, however, 
ECGs will be measured in triplicate predose and 4 hours postdose, and a ±30-minute sampling window is allowed for measurement at 4 hours postdose. Triplicate ECGs will be recorded at 
least 30 seconds apart from each other, not exceeding a time period of 3 minutes for the completion of all 3 ECGs. 12-lead ECGs during the Outpatient visit will be measured once per day 
whenever possible. 
m. Blood sampling for immunogenicity assessments will be performed only for hospitalized patients after admission on Day-1, Day 10, and Day 30. 
n. Injection site assessments will be performed predose, within 1 hour postdose and at 4 and 12 hours postdose on Day 1, and then between 9:00 AM and 12:00 PM daily from Day 2 through 
Day 7. 
o. Blood will be collected for PK assessments predose and at 1, 4, 8, 12 (Day 1), 24, 36 (Day 2), 48, 54, 60 (Day 3), 72, 78, 84 (Day 4), 96, 102, 108 (Day 5), 120 (Day 6), 144 (Day 7), 216 
(Day 10), 384 (Day 17) and 696 (Day 30) hours postdose. The time points for citrulline sampling are identical to those for PK blood sampling, but 126 hours (Day 6) will be added. PK 
sampling times may be adjusted between the cohorts in case available PK data show that other time points would be more beneficial. See Table 2-1 for the PK sampling schedule. 
p. If the PK sampling time points are changed, the citrulline sampling times may be adjusted accordingly. See Table 2-1 for the citrulline sampling schedule. 
q. Blood will be collected for GIP, GLP-1, C-peptide, glucagon and insulin immediately before administration and once daily on Days 4 and 7, at the Day 17 Outpatient visit and at the Day 
30/Follow-up visit. If the PK sampling time points are changed, sampling times may be adjusted accordingly. 
r. Blood will be collected for IGF-1 and KGF immediately before administration and once daily on Days 4 and 7, at the Day 17 Outpatient visit and at the Day 30/Follow-up visit. If the PK 
sampling time points are changed, sampling times may be adjusted accordingly.

1. INTRODUCTION 
1.1. Background 
Hanmi Pharmaceutical is developing HM15912, a synthetic substance produced by 
combining a GLP-2 analogue (GT15912) and a human immunoglobulin G4 Fc fragment 
(HMC001) with aldehyde-polyethylene glycol-aldehyde (ALD-PEG-ALD), a bifunctional 
bonding molecule1. This medicinal product is developed as a new treatment for the short 
bowel syndrome (SBS). 
The SBS is a rare disease caused by broad surgical resection of the small intestine or as a 
result of an inborn condition. It is characterized by a decrease in the intestinal absorption 
surface area and subsequent malabsorption of essential macronutrients and micronutrients2. 
There is no definitive treatment for the SBS at present, and patients with a short residual 
bowel are likely to rely on parenteral nutrition (PN). Long-term PN may cause life-
threatening complications such as sepsis, osteopenia, and chronic liver diseases3. 
GLP-2 is known to increase the intestinal absorption surface area by promoting the growth of 
crypt cells within the intestine, and it has been developed as a treatment to reduce SBS 
patients' dependency on PN. GLP-2 is a major hormone that affects many aspects of intestinal 
physiology such as growth, barrier function, digestion, absorption, movement, and blood 
flow4. The half-life of GLP-2 within the human body is very short (approximately 7 minutes), 
so the GLP-2 medication currently on the market, teduglutide (GATTEX®), has been 
developed to have resistance to the dipeptidyl peptidase-4 (DPP-4) enzyme. Of note, however, 
that the half-life of teduglutide is 1.3~2.2 hours, which is still short, and it is provided as 
freeze-dried powder, thereby requiring medical staff to go through complicated preparation 
process to administer it to patients5. Thus, teduglutide cannot be a sufficient treatment option 
for SBS patients requiring long-term PN. 
Unlike teduglutide, HM15912 is a GLP product that prolongs the half-life and enhances 
stability by decreasing renal excretion resulting from increased molecular weight and with 
recycling of vascular endothelial cells through FcRn binding. GT15912 of HM15912 as a GLP-
2 analogue has been designed to be more effective than teduglutide, and PK and pharmaceutical 
stability have been enhanced by increasing water solubility through the binding of GT15912 
and HMC001. The nonclinical PD study results show that HM15912 induced human GLP-2 
receptor-mediated cAMP accumulation dose-dependently in hGLP-2R/CHO-K1 cells and 
stimulated IGF-1 production in mice's primary intestinal subepithelial myofibroblasts 
(ISEMFs). The secreted IGF-1 binds with the tyrosine kinase IGF-1 receptor in crypt and this is 
related to crypt cell proliferation through the paracrine signaling. The PD of HM15912 has been 
verified from in vivo experiments as well. When HM15912 was subcutaneously dosed multiple 
times to mice and rats, the growth of their intestine, especially the wet weight of their small 
intestine, has increased dose-dependently and shown higher intestinotrophic efficacy compared 
to teduglutide. Furthermore, it has been proved that there is a relationship between the physical 
improvement of intestinal environment and the functional improvement of intestine since the 
intestinal growth led by HM15912 in SBS rat models has enhanced nutrient absorption as a 
result. Based on such PD and PK properties, HM15912 is expected to be a promising option for 
treating the SBS. 
Additional details can be found in the Investigator's Brochure (IB)1.

Final 4.2

Apr 06, 2020 
This first-in-human (FiH) study evaluates the safety, tolerability, PK and PD of HM15912, a 
synthetic conjugate of a GLP-2 analogue (GT15912) and a human immunoglobulin G4 Fc 
fragment (HMC001). 
This study is conducted to define a tolerable dose range for most subjects and to provide 
exploratory data on the potential for prolonged intestinal absorption increase in healthy 
population. The results of this clinical study will provide data on design and dose selection for 
subsequent studies. 
1.3. Risk-benefit Assessment 
While HM15912 has not been evaluated in humans, clinical experiences with other GLP-2 
analogues and known pharmacologic and preclinical data suggest the following expected side 
effects: 
• Gastrointestinal: Abdominal pain, abdominal discomfort, nausea, vomiting, abdominal 
inflation, dysorexia, colon polyp, small intestinal tumor, intestinal obstruction, 
gallbladder/biliary tract disease, pancreatic disease 
• Respiratory: Upper airway infection, cough 
• Immunological: Hypersensitivity reaction 
• General: Injection site reaction, pyrexia 
• Investigational: Slight increase of amylase and lipase, slight decrease of ALP, ALT, and 
AST 
• Nervous system: Sleep disorder 
• Skin lesion: Skin hemorrhage 
• Fluid overload 
There will be no direct health benefit for healthy subjects from receipt of the investigational 
product (IP). The protocol has been designed to minimize the risk to research participants. 
Subjects will be monitored to detect AEs during the study and followed appropriately to 
ensure resolution of AEs. Sentinel dosing will be employed within each cohort, and available 
blinded safety data (together with PK/PD data if possible) will be assessed after each dose 
level to determine if it is safe to escalate to the next planned dose.

3. OVERALL DESIGN AND PLAN OF THE STUDY 
3.1. Overview 
This is a double-blind, randomized, placebo-controlled, single ascending dose (SAD) study to 
assess the safety, tolerability, PK and PD of the SC administration of HM15912 in healthy 
Korean subjects. 
The study will be conducted in approximately 5 sequential dosing cohorts, enrolling 8 
subjects per cohort. Subjects will be randomized to HM15912 or placebo in a ratio of 6:2 (6 
active, 2 placebo). When necessary, one dosing cohort may be added or removed. 
Each cohort will be divided in 2 blocks in this FiH study in order to implement the sentinel 
dosing approach. Within each cohort, the first block will consist of 2 sentinel subjects; 1 
subject will receive HM15912, and 1 subject will receive matched placebo. The second block 
will consist of 6 subjects randomized to receive HM15912 (n = 5) or matched placebo (n = 1). 
Individual subjects in the second block will be dosed at least 24 hours after the first block 
when safety and tolerability are found to be satisfactory by the Principal Investigator. 
Following an overnight fast of at least 10 hours, each subject will receive a single dose of 
either HM15912 or matched placebo-administered SC in the abdomen on the morning (8:00 
AM - 10:00 AM) of Day 1. Subjects will continue fasting through approximately 4 hours 
postdose. Water intake is also limited for approximately 1 hour before dosing and 
approximately 2 hours after dosing. 
The planned maximum dose of HM15912 is 1.5 mg/kg; however, higher doses may be 
administered if safety is confirmed in previous cohorts. If dose is escalated to 1.5 mg/kg or 
above, MFDS approval will be obtained. After at least 6 subjects (HM15912, n ≥ 4) in each 
cohort have completed assessments through at least Day 17, blinded safety data will be 
reviewed and a dose decision/dose escalation decision for the subsequent cohort will be made 
by the Principal Investigator and the Sponsor. If there are PK/PD data obtained from the 
preceding or current cohorts, the PK/PD data will be reviewed as well when necessary. 
Escalation will only proceed if safety and tolerability data related to the dose of the prior 
cohort are verified. Determination of whether to proceed to the next cohort will be made by 
the Principal Investigator and the Sponsor, and changes in the dose and the number of cohorts 
will be approved by the MFDS and the IRB. 
PK data will only be reviewed if available. After review of the PK data from the preceding or 
current cohorts, changes in time points for PK collection, clinical laboratory assessments, and 
PD collection may be required and will be approved by the MFDS and the IRB. 
If dose escalation is stopped based on available blinded safety data, the current dose level will 
be considered as the minimum intolerable dose (MID). The dose just below the MID will be 
regarded as the maximum tolerated dose (MTD). If the dose escalation is stopped due to 
reaching exposure limit without dose-limiting safety findings, the MTD cannot be 
determined. Dose de-escalation may occur in the last cohort or additional cohorts to further 
refine clinically relevant dose levels. 
Stopping rules are described in Section 3.4. 
 
The study will be comprised of: 
• A Screening visit up to 28 days before dosing

• An inpatient assessment period of approximately 8 days, with admission to the institution 
on Day-1, dosing on Day 1, and discharge on Day 7 once the planned schedule is 
completed 
• Two Outpatient visits on Day 8 (± 4 hours), Day 10 (± 1 day), Day 17 (± 1 day) and Day 
30 (±3 days) 
• A final Follow-up visit on Day 44 (± 3 days) 
The total duration of the clinical study per subject will be up to approximately 72 days, 
including the Screening period. 
Procedures related to the clinical study are detailed in the Schedule of Assessments, the PK 
Sampling Schedule, the Citrulline Sampling Schedule, and the PD Sampling Schedule (Table 
1-1 and 1-2, Table 2-1 and 2-2, Table 3-1 and 3-2, respectively). 
Doses will be administered via SC injection to subjects in approximately 5 dose cohorts. 
Additional cohorts may be enrolled and proceed at a dose higher or lower than the planned 
maximum dose of 1.5 mg/kg, if deemed appropriate by the Principal Investigator and the 
Sponsor, but cohorts are planned as follows:

3.3. Rationale for the Study Design 
This study evaluates the safety, tolerability, PK and PD of single ascending doses of 
HM15912 administered via SC injection. This study was designed to minimize bias and to 
obtain reference data (i.e., data from placebo-treated subjects) which will aid in the 
interpretation of results through double blind and placebo control. 
For this FiH study, sentinel dosing will be utilized for each cohort. This will minimize the 
number of subjects affected by rapid side effects after HM15912 administration. The Principal 
Investigator and the Sponsor will review available blinded safety and tolerability data after 
each cohort to determine the next dose and then decide whether the dose escalation should be 
stopped or whether the dose should be increased/decreased in the subsequent cohort. If 
PK/PD data have been obtained, they can be used for reference. This is not mandatory, 
however. 
The planned safety assessments that will be performed during the study are measures for 
ensuring the safety of subjects during a clinical trial. The PK sampling schedule is considered 
appropriate given the information obtained from the nonclinical study results of HM15912. 
The rationale for dose selection is discussed in Section 5.2. 
Based on the in vivo effect of endogenous GLP-2, the exogenous administration of HM15912, a 
GLP-2 analogue, is expected to expand the mucous epithelium of the small intestine and colon 
resulting from the proliferation of crypt cells1. Plasma citrulline is a nonprotein amino acid that 
is mostly synthesized in the small intestine cells, and is well-known as a noninvasive plasma 
biomarker for intestinal cell mass2. Apolipoprotein AIV is also mostly synthesized in the small 
intestine cells, and previous studies have shown the correlation between apolipoprotein AIV and 
plasma citrulline levels3. Therefore, effect of HM15912 on expansion of the intestinal mucous 
membrane will be explored by measuring plasma citrulline after HM15912 administration. The 
serum proteins, albumin and prealbumin, and serum lipid panel will also be evaluated to 
observe changes in nutrient status of subjects resulting from expansion of the intestinal mucous 
membrane4. 
GLP-2 affects the pancreas and is involved in the secretion of glucagon and maintenance of 
glucose homeostasis1. These pancreatic hormones are balanced in a physiological condition, 
and this study will explore the effect of GLP-2 administration on the homeostasis. 
3.4. Dose Escalation and Study Stopping Criteria 
Dose escalation will be stopped if 1 of the following conditions applies: 
• Death of a subject in 1 cohort, at any time, that is considered to be related to the IP, judged 
by the Principal Investigator 
• One or more of the subjects in 1 cohort have experienced serious AE that is considered to 
be related to the IP, judged by the Principal Investigator.  
• Two or more of the subjects in 1 cohort have experienced severe AE that is considered to 
be related to the IP, judged by the Principal Investigator. 
• Two or more of the subjects in 1 cohort have experienced moderate AEs that persist for 
more than 7 days and are considered to be related to the IP, judged by the Principal 
Investigator. 
• Two or more of the subjects in 1 cohort develop similar clinically significant laboratory, 
significant ECG or vital sign abnormalities, or severe AEs in the same organ class,

indicating dose-limiting intolerance. Dose escalation may proceed if after review of the 
data by the Principal Investigator and discussion with the Sponsor, it is concluded that the 
events are not drug related. 
• It is determined that the limit of safety and/or tolerability has been reached. Decision will 
be made between the Sponsor and the Principal Investigator. 
If any delayed reactions occur in subjects administered HM15912 during this study, the 
Principal Investigator will immediately stop the administration and take appropriate medical 
measures. If delayed reactions are suspected to be drug hypersensitivity reactions, appropriate 
medical measures will be taken in accordance with 7.9. Handling of Hypersensitivity 
Reactions. If Principal Investigator and Sponsor discuss and agree that administering 
HM15912 to other subjects is an unacceptable risk, they may stop the study as below. 
The Principal Investigator and the Sponsor may stop the clinical study after an appropriate 
discussion if conditions or events including, but not limited to, the following occur during the 
study. A sufficient written statement on the reason for stopping the study will be submitted to 
the IRB. 
• If clear risks or unacceptable risks are found in the subjects enrolled in this clinical study 
• If the Sponsor decides to postpone or stop development of the IP

4. STUDY POPULATION 
The study population will consist of healthy male and female volunteers. Subjects must be 
able to provide written informed consent and meet all the inclusion criteria and none of the 
exclusion criteria. 
4.1. Number of Subjects 
A total of approximately 40 subjects will be enrolled in the clinical study (N = 8 per cohort 
with 6 randomized to HM15912 and 2 randomized to matching placebo within each group) 
according to the inclusion/exclusion criteria. Enrolling 8 subjects per cohort 
(HM15912:placebo=6:2) has been set based on the experience and the general properties of 
exploratory studies, and this matches the typical sample size used in similar studies conducted 
to assess safety and PK. Therefore, no formal sample size calculation will be performed (refer 
to Section 8.11). 
4.2. Inclusion Criteria

or post-menopausal for ≥ 12 months. Postmenopausal status will be confirmed through 
testing of follicle-stimulating hormone (FSH) levels ≥ 40 IU/L at the Screening visit for 
amenorrheic female subjects ≤ 60 years of age. 
Male subjects must be surgically sterile (at least 1-year post vasectomy), abstinent or if 
engaged in sexual relations with women of child-bearing potential, the subject and his 
partner must be using the following acceptable effective or medically recognized dual

tubal occlusion, hysterectomy, bilateral salpingectomy, bilateral oophorectomy), 
intrauterine contraception/device of the sexual partner 
• Dual protection contraceptive method: Combinational use of physical barrier methods 
(male condom, female condom and diaphragm for the sexual partner, sponge, cervical 
cap), spermicide for females in the form of foam/gel/film/cream/suppository, oral or 
hormonal contraceptives for the sexual partner

5. INVESTIGATIONAL PRODUCT 
5.1. Identity of the Investigational Products 
5.1.1. Study Drug 
The study drug will be provided by Hanmi Pharmaceutical Co., Ltd. in a prefilled syringe. 
The concentration of HM15912 is 30 mg/mL and the fill volume is 0.52 mL including 
overfill. 
5.1.2.  Control Drug 
The control drug is a placebo matching the study drug HM15912. It is a sterile solution in a 
prefilled syringe without the main components of the study drug and is identical to the study 
drug in terms of formulation and appearance. Its fill volume including overfill is 0.52 mL, and 
it is provided by Hanmi Pharmaceutical Co., Ltd. 
5.2. Dose Rationale Including Time of Dosing 
The proposed starting dose of HM15912 is 0.05 mg/kg based on the results of the 4-week 
toxicology assessment in rats and monkeys. The NOAEL was 10 mg/kg in rats and 18 mg/kg 
in monkeys. The human equivalent dose was 1.61 mg/kg for rats and 5.8 mg/kg for monkeys. 
As suggested in the 2005 FDA Guidance for Industry Estimating Maximum Safe Starting 
Dose in Initial Clinical Trials for Therapeutics in Adult Healthy Volunteers, the maximum 
recommended starting dose (MRSD) applying a safety factor of 10 to the human equivalent 
dose calculated in rats and monkeys is 0.16 mg/kg for rats and 0.58 mg/kg for monkeys. The 
selected initial dose of 0.05 mg/kg provides the safety margin that is approximately 3-fold in 
rats and approximately 12-fold in monkeys, compared to the MRSD. 
The planned maximum dose of HM15912 is 1.5 mg/kg; however, higher doses may be 
administered based on the safety results of previous cohorts. The MTD of HM15912 was not 
determined since no toxicity was found in the 2-week toxicology assessment (10 mg/kg in rats 
and 18 mg/kg in monkeys). The set maximum dose provides a 1.1-fold safety margin 
compared to the human equivalent dose calculated at the rat NOAEL and a 3.9-fold safety 
margin compared to the human equivalent dose calculated at the monkey NOAEL. The 
similar GLP-2 analogue, Gattex®, has shown appropriate tolerability up to 80 mg (SC, 
administered once per day for 8 days) with repeated doses in healthy subjects; another GLP-2 
analogue, ZP1848 (Zealand Pharma, under clinical development), has shown appropriate 
tolerability up to 96 mg with single doses in healthy subjects.6,7 
Following an overnight fast of at least 10 hours, each subject will receive a single dose of either 
HM15912 or matched placebo administered SC in the abdomen on the morning of Day 1 in 
order to permit time for postdose safety, PK and PD assessments throughout the day. Subjects 
must continue fasting for approximately 4 hours after administration. Water consumption will 
also be limited for 1 hour before dosing and for approximately 2 hours after dosing. After the 
planned blood sampling (clinical laboratory tests) and testing (12-lead ECG) are performed 4 
hours postdose, subjects will be served lunch by the institution.

Apr 06, 2020 
5.2.1. Rationale for Dose Escalation 
After at least 6 subjects (HM15912, n ≥ 4) in each cohort have completed assessments 
through at least Day 17, blinded safety data will be reviewed and a dose decision/dose 
escalation decision for the subsequent cohort will be made by the Principal Investigator and 
the Sponsor. If PK/PD data have been obtained, they can be reviewed as well. This is not 
mandatory, however. The parties will decide about the next dose level taking into 
consideration the outcome from the blinded safety review, the stopping rules (Section 3.4), 
and the available PK/PD data.  
Depending on the nature, frequency and severity of the safety profile observed in the clinical 
study, the Principal Investigator and the Sponsor will decide one of the followings. If dose is 
escalated to 1.5 mg/kg or above or dose is reduced from the planned dose, approval of the 
MFDS and the IRB will be obtained. 
1. Proceed with dose escalation and determine the next higher dose; 
2. Stop dose escalation (i.e., no further dosing); 
3. Investigate a lower dose level (intermediate between the current and prior ones). 
5.2.2. Definition of the Maximum Tolerated Dose 
If dose escalation is stopped based on available safety data, the current dose level will be 
considered as the MID. The dose just below the MID will be regarded as the MTD. If the dose 
escalation is stopped due to reaching exposure limit without dose-limiting safety findings, the 
MTD cannot be determined. 
5.3. Supply, Packaging, Labelling and Storage 
The IPs will be packaged by Hanmi Pharm. Co., Ltd. according to local legal requirement and 
labelled according to applicable health authority requirements. 
All supplies of IPs must be stored in accordance with the manufacturer’s instructions, 
refrigerated between 2°C and 8°C and protected from light (i.e., kept in cartons until ready for 
use). HM15912 is stable up to 12 hours at room temperature. The Investigator and the 
institution's staff in charge will check every day if the temperature for IP storage is 
appropriately maintained and the thermometer is properly functioning. If temperature 
excursions are found, it should be reported immediately. IPs must be handled and retained 
properly and safely by the clinical research pharmacist at the institution and stored in a 
secure area accessible only to the Investigator and clinical research pharmacist. 
5.4. Drug Preparation, Dispensing, Accountability and Destruction 
The IPs will be provided in prefilled syringes. Dose administration will be based on the body 
weight of a subject rounded to 1 decimal place as measured on the day before dosing. The 
injection volume will also be determined by dose level. HM15912 concentration is 30 
mg/mL. The determined injection volume will be prepared in dosing syringes in accordance 
with the instructions contained in the pharmacy manual. 
Each administered IP will be recorded, and used syringes and needles will be discarded. 
The Investigator or clinical research pharmacist is responsible for maintaining accurate

records regarding transportation and dispensing of IPs. The IPs must be used only for this 
clinical study. The unblinded monitor will check IP accountability during the clinical study 
period and at completion of the study.  
All unused IPs must be destroyed by the Sponsor according to IP destruction-related 
guidelines, and documents regarding the destruction must be managed. Therefore, unused IPs, 
packages, and IP labels must be returned to the Sponsor upon completion of the study or 
during the study if needed. Used or opened IPs will be destroyed properly according to the 
institution's SOP. The Investigator or clinical research pharmacist will provide one copy of IP 
accountability records for the Sponsor. 
5.5. Subject Identification and Randomization 
5.5.1. Screening Numbers 
All screened subjects are assigned a unique subject identification (SID) number. The SID 
numbers are sequentially assigned in the order of obtaining written consent, and contain 4 
digits (e.g., the numbers are sequentially allocated from X001 and X represents an institute) 
that identify subjects from the time of Screening until the time of randomization. Enrolled 
subjects who drop out of the clinical study before randomization after consent has been 
obtained will retain their SID number. 
5.5.2. Randomization Numbers 
Randomization numbers are assigned to subjects after completing the Screening and re-
checking the inclusion/exclusion criteria on Day-1. Randomization numbers are assigned in 
the order that subjects who meet all the inclusion/exclusion criteria of this study get 
hospitalized on Day-1. Randomization will be performed through the EDC, and 
randomization numbers will be assigned by the system. The randomization code (study drug 
or control drug) of each randomization number will be maintained in a room with restricted 
access to the non-blinded clinical research pharmacist only, and will be accessed by other 
personnel only in case of unblinding, as described in Section 5.8. A randomization number 
will include 3-digit subject numbers as shown in Table 5.

1 The planned maximum dose of HM15912 is 1.5 mg/kg; however, higher doses may be administered if safety is 
confirmed in previous cohorts. 
Once a randomization number has been allocated to one subject, it may not be assigned to 
another subject. If subjects withdraw prematurely from the study and are replaced under the 
direction of the Sponsor, then a replacement randomization number will be assigned when a 
replaced subject has successfully completed Screening. A replacement randomization code 
will be generated such that replacement subjects are assigned to the same treatment as the 
discontinued subjects. The replacement randomization code will differ only in randomization 
numbers. It is composed of 4 digits by adding “1” in front of the randomization number for a 
withdrawn subject. For example, if Subject 202 withdraws and is replaced, then the 
randomization number for the replacement subject will be 1202. 
5.6. Administration of Investigational Products 
HM15912 or placebo will be administered via SC injection into the abdomen on the morning 
of Day 1 after a minimum 10-hour overnight fast. Subjects will continue fasting through 
approximately 4 hours postdose. Water intake is also limited for approximately 1 hour before 
dosing and approximately 2 hours after dosing. After the planned blood sampling (clinical 
laboratory tests) and testing (12-lead ECG) are performed 4 hours postdose, subjects will be 
served lunch by the institution. 
5.7. Compliance 
Dosing will be performed by the Investigator, but if a nurse administers, that will be carried 
out under the Investigator's supervision. Comments will be recorded if there are any 
deviations from the planned dosing procedures.

5.8. Blinding and Breaking the Blind 
The clinical study will be performed in a double-blind manner with the exception of the 
persons involved in the preparation of the IPs. These persons will not be involved in any other 
study activities. 
The study blind should not be broken except in a medical emergency (where knowledge of the 
IP administered would affect the treatment of the emergency), or if dose limiting toxicities 
occur or if it is necessary for dose escalation decisions as described in Section 3.4. The 
decision to break the blind will be made by the Principal Investigator on a case-by-case basis. 
The Investigator or the Principal Investigator will contact Hanmi Pharmaceutical Co., Ltd. 
and deliver related documents when breaking the blind. The results of breaking the blind for 
each subject will not be revealed. The Investigator or the Principal Investigator will record 
blind-breaking dates and reasons in the CRF. 
If blinding is not maintained in the Investigator, the institution's staff or subjects, the subject 
must be withdrawn. If blinding is accidently broken during the study or blinding is broken 
before completion of the study due to SAEs, the Investigator must record this and rapidly 
report to Hanmi Pharmaceutical Co., Ltd. However, if blinding is broken for ethical reasons 
or blind breaking is seen to have little effect on the subject's safety, the subject may continue 
to participate in the clinical study in the judgment of the Investigator after discussing with 
Hanmi Pharmaceutical Co., Ltd. 
After database lock, the overall randomization code will be broken. 
5.9. Prior and Concomitant Medications 
Use of prescription, herbal, OTC (including acetaminophen and vitamins) medications is 
prohibited from 3 days prior to the Screening visit until the Follow-up visit, unless approved 
by the Principal Investigator. Use of dietary supplements is prohibited from Inpatient 
Treatment Period until the Follow-up visit. Use of concomitant medication is permitted if 
deemed by the Principal Investigator to be necessary for treatment of an AE. 
Other IPs cannot be used concurrently during the study, and there are no other concurrent 
drugs prohibited. 
5.10. Overdose of Investigational Product  
Standard symptomatic support measures should be used in the case of excessive 
pharmacological effects or overdose. No antidotes are available.

6.2.1.1. 
Definitions 
6.2.1.1.1. 
Definition of Adverse Event 
Any untoward medical occurrence in subjects and which does not necessarily have a causal 
relationship with the IP. An AE can therefore be any unfavorable and unintended sign 
(including abnormal laboratory findings), symptom or disease, whether or not it is related to 
the IP. 
Other untoward events occurring in the framework of a clinical study will be recorded as AEs, 
e.g., those occurring during treatment-free periods (including post-treatment Follow-up 
periods), in association with study-related procedures and assessments, or under placebo. 
Concomitant illnesses that existed prior to entry into the clinical study will not be considered 
as AEs unless they worsen during the treatment period. If a subject is withdrawn prior to 
randomization, AEs occurring in him/her will not be collected. 
6.2.1.1.2. 
Definition of Serious Adverse Event 
An SAE is defined as any untoward medical occurrence that at any dose: 
• Results in death 
• Is life-threatening; this means that a subject was at risk of death at the time of the event; it 
does not mean that the event hypothetically might have caused death if it were more severe 
• Requires inpatient hospitalization or prolongation in existing hospitalization 
• Results in persistent or significant disability/incapacity or substantial disruption of the 
ability to conduct normal life functions 
• Is a congenital anomaly/birth defect, or 
• Is another important medical event (see below) 
Important medical events that do not result in death, are not life-threatening or do not require 
hospitalization may be considered SAEs when, based on appropriate medical judgment, they 
may jeopardize a 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 in a physician’s office, blood 
dyscrasias or seizures that do not result in inpatient hospitalization, and the development of 
drug dependency or drug abuse. 
A distinction should be drawn between serious and severe AEs. Severity is a measure of 
intensity whereas seriousness is defined by the criteria above. For example, a mild degree of 
gastrointestinal bleeding requiring an overnight hospitalization for monitoring purposes 
would be considered an SAE, but is not necessarily severe. Similarly, an AE that is severe in 
intensity is not necessarily an SAE. For example, alopecia may be assessed as severe in 
intensity but would not be considered an SAE. 
Medical and scientific judgment should be exercised in deciding if an AE is serious and if 
expedited reporting is appropriate. 
6.2.1.2. 
Recording of Adverse Events 
AEs should be collected and recorded for each subject from the date he/she signs the ICF until 
the end of their participation in the study, i.e., the subject has discontinued or completed the 
study. If a subject is withdrawn prior to randomization, AEs occurring in him/her will not be 

Hanmi Pharmaceutical Co., Ltd. 
HM-GLP2-101 
 
CONFIDENTIAL 
Final 4.2 
Page 52 of 75 
Apr 06, 2020 
collected. 
All AEs and SAEs will be recorded in source documents and, if applicable, in relevant eCRF 
pages and SAE forms. The Investigator is responsible for reporting AEs or SAEs using 
medical terms if possible. 
AEs may be volunteered spontaneously by a subject, or discovered by the study staff during 
physical examinations or by asking an open, non-leading question such as "How have you 
been feeling since you were last asked?" All AEs and any required remedial action will be 
recorded. The type of AE, date (and time, if known) of AE onset, date (and time, if known) of 
AE end, severity and action taken of the AE will be documented together with the 
Investigator’s assessment of the seriousness of the AE and causal relationship to IP and/or 
study procedure. 
All AEs should be recorded using standardized medical terms. AEs will be coded using the 
Medical Dictionary for Regulatory Activities (MedDRA). 
6.2.1.3. 
Assessment of Adverse Events 
Each AE will be assessed by the Investigator with regard to the categories discussed in the 
following sections. 
6.2.1.3.1. 
Severity 
The Investigator will assess all AEs for severity in accordance with the following standard 
ratings. 
• Mild: Ordinarily transient symptoms, does not influence performance of a subject’s daily 
activities. Treatment is not ordinarily indicated. 
• Moderate: Marked symptoms sufficient to make a subject uncomfortable. Moderate 
influence on performance of a subject’s daily activities. Treatment may be necessary. 
• Severe: Symptoms cause considerable discomfort. Substantial influence on performance of 
a subject’s daily activities. May be unable to continue in the study and treatment may be 
necessary. 
When changes in the intensity of an AE occur more frequently than once a day, the maximum 
intensity for the event should be noted for that day. Any change in severity of signs and 
symptoms over a number of days will be captured by recording a new AE, with the amended 
severity grade, and the date (and time, if known) of the change. 
6.2.1.3.2. 
Causality 
The Investigator will assess the causality/relationship between the IP and the AE. One of the 
categories described in Table 6 should be selected based on medical judgment, considering 
the definitions below and all contributing factors. 
 
Table 6 
Assessment of Relationship of Adverse Events to Investigational Product 
 
Related 
The AE follows a reasonable temporal sequence from IP administration, and 
cannot be reasonably explained by a subject’s clinical state or other factors (e.g., 
disease under study, concurrent diseases, or concomitant medications). 
The AE follows a reasonable temporal sequence from IP administration, and

represents a known reaction to the drug under study or other drugs in its class, or 
is predicted by the known pharmacological properties of the drug. 
The AE cannot be judged because of insufficient or contradictory information. 
The AE cannot be supplemented or verified. 
Not related 
The AE does not follow a reasonable temporal sequence from IP administration, 
or can be reasonably explained by a subject’s clinical state or other factors (e.g., 
disease under study, concurrent diseases, and concomitant medications). 
6.2.1.3.3. 
Seriousness 
Severity is a measure of intensity whereas seriousness is defined by the criteria in Section 
6.2.1.1.2. 
6.2.1.4. 
Reporting of Serious Adverse Events 
All SAEs that occur during the period of observation (from the date the subject signs on the 
ICF until the follow-up visit), whether they are considered to be related to the IP or not, must 
be reported to the Sponsor within 24 hours after becoming aware of the occurrence by fax or 
email via the completed SAE report. 
Serious AEs occurring after the Follow-up visit (end of the clinical study) should be reported 
to the Sponsor by the Principal Investigator if the Principal Investigator considers there is a 
reasonable causal relationship with the IP. 
The minimal information required for an initial report is: 
• Sender of report (name, address of Principal Investigator) 
• Subject identification (Screening/randomization number, NOT subject name) 
• Protocol number 
• Description of SAE (Start date, seriousness) 
• Details of the IP (Dosage, frequency, start date, end date) 
• Causality assessment 
However, as far as possible all points on the SAE form should be covered in the initial report, 
and the completed SAE form must be faxed or emailed to the Sponsor. 
After receipt of the initial report, the Sponsor will review the information and, if necessary, 
contact the Principal Investigator to obtain further information for assessment of the event. 
The Principal Investigator will be responsible for informing the IRB of the SAE, and the 
Sponsor will be responsible for informing the regulatory authorities of the SAE as per local 
requirements.

Follow-up of Adverse Events 
All AEs experienced by a subject, irrespective of the suspected causality, will be monitored 
until the event has resolved, until any abnormal laboratory values have returned to baseline or 
stabilized at a level acceptable to the Principal Investigator, until there is a satisfactory 
explanation for the changes observed or until the subject is lost to follow-up. 
If there are any changes of condition in subjects reported with SAEs (e.g., discharge after 
admission, situation worsened) or if any additional information is collected, the Investigator 
will complete an SAE report and send it to the Sponsor by fax or email within 24 hours after 
becoming aware of the occurrence. 
6.2.1.6. 
Suspected Unexpected Serious Adverse Reactions 
Any AE that is considered to be a suspected unexpected serious adverse reaction (SUSAR) 
has additional reporting requirements, as described below: 
• If the SAE is fatal or life-threatening, associated with the use of the IP, and unexpected, 
the Sponsor will report it to the regulatory authorities within 7 calendar days after the 
Sponsor learns of the event, and the Principal Investigator will report it to the IRB in 
accordance with the institution regulations. If the required information in the SAE report is 
not fully reported, however, the Sponsor will report additional follow-up information to 
the regulatory authorities within 15 calendar days after the Sponsor first learns of the 
event, and the Principal Investigator will make an additional report in accordance with the 
institution regulations. 
• If the SAE is not fatal or life-threatening but is otherwise serious, associated with the use 
of the IP, and unexpected, the Sponsor will report it to the regulatory authorities within 15 
calendar days after the Sponsor learns of the event, and the Principal Investigator will 
report to the IRB in accordance with the institution regulations. 
The Sponsor will notify the Principal Investigator of relevant information about SUSARs that 
could adversely affect the safety of subjects in a timely fashion. Follow-up information may 
be submitted if necessary.

6.2.1.7. 
Pregnancy 
The Sponsor has a responsibility to monitor the outcome of all pregnancies reported during 
the clinical study. 
Pregnancy alone is not regarded as an AE unless there is a suspicion that the IP may have 
interfered with the effectiveness of a contraceptive medication. Elective abortions without 
complications should not be regarded as AEs, unless they were therapeutic abortions (see 
below). Hospitalization for normal delivery of a healthy newborn should not be considered an 
SAE. 
If a female subject is confirmed to be pregnant, IP administration will be stopped and her 
participation in the clinical study will be terminated. Immediately after becoming aware of a 
subject's pregnancy, the Investigator should report to the Sponsor the fact that she is pregnant 
together with the subject number and receive her consent that her pregnancy information will 
be collected and shared with the Sponsor. If the subject agrees, the Investigator must report to 
the Sponsor via the completed Clinical Trial Pregnancy Report; initial report within 24 hours 
after obtaining the subject's consent. Any pregnancy of a male subject's partner must also be 
reported to the Sponsor in the same manner as the pregnancy in a female subject. The 
Principal Investigator must follow-up and document the course and the outcome of all 
pregnancies even if the subject has been withdrawn from the clinical study or if the clinical 
study has finished. All outcomes of pregnancy (e.g., the normal delivery or elective abortion) 
must be reported by the Principal Investigator to the Sponsor via the completed Clinical Trial 
Pregnancy Report; follow-up report within 24 hours after becoming aware of the outcome. 
Any SAE that occurs during pregnancy must be recorded on the SAE report form (e.g., 
maternal serious complications, therapeutic abortion, ectopic pregnancy, stillbirth, neonatal 
death, congenital anomaly, birth defect) and reported within 24 hours (based on the calendar 
day) in accordance with the procedure for reporting SAEs. 
6.2.2. Clinical Laboratory Assessments 
The clinical laboratory tests specified in Table 7 will be determined at time points specified in 
the Schedule of Assessments (Table 1-1 and 1-2). 
Clinical laboratory tests will be performed by the laboratories specified in the Laboratory 
Manual(s). Samples will be collected in appropriate tubes and handled according to standard 
procedures of the applicable laboratory.

significant, the subject's participation in the study will be decided based on the Principal 
Investigator's medical judgment. Additional testing during the study may be done if medically 
indicated. If a clinically significant abnormality is found in the samples taken from the date 
the ICF is signed until the Follow-up visit, it should be recorded as an AE and the subject will 
be followed until the test(s) has (have) normalized or stabilized, at the discretion of the 
Principal Investigator.

6.2.3. Vital Signs 
Vital signs will be assessed at the time points specified in the Schedule of Assessments (Table 
1-1 and 1-2). The following vital signs will be measured: 
• Blood pressure (systolic and diastolic [mmHg]) 
• Pulse (bpm) 
• Tympanic temperature (°C) 
• Respiratory rate (breaths per minute) 
BP and pulse will be measured for 2 consecutive times after a subject has been lying down or 
sitting to rest ≥ 5 minutes, and mean values will be recorded. 
6.2.4. 12-lead Electrocardiograms 
12-lead ECGs will be performed at the time points specified in the Schedule of Assessments 
(Table 1-1 and 1-2). ECGs will be measured 3 times repeatedly predose and 4 hours postdose 
each on Day 1 only. A deviation of ± 30 minutes from the collection time points is allowed in 
case of measurement 4 hours after dosing. 
The 12-lead ECGs will be performed after a subject has been resting supine for ≥ 5 minutes. 
Triplicate ECGs will be recorded at least 30 seconds apart from each other, not exceeding a 
time period of 3 minutes for the completion of all 3 ECGs. The following ECG parameters 
will be collected: Ventricular rate, PR interval, QRS interval, RR interval, QT interval and QT 
interval corrected for heart rate (QTc) (QTc using Bazett’s correction [QTcB] and QTcF). 
All ECGs must be evaluated by the Investigator for the presence of abnormalities. If any 
clinically significant abnormality is observed, it must be recorded as an AE. 
6.2.5. Injection Site Assessments 
Injection site assessments will be performed at the time points specified in the Schedule of 
Assessments (Table 1-1 and 1-2). 
After injection of the study drug, the injection site will be marked with a pen. Injection site 
assessments will be performed predose, within 1 hour postdose and at 4 and 12 hours 
postdose on Day 1, and then once per day between 9:00 AM and 12:00 PM from Day 2 
through Day 7. A deviation of ± 30 minutes from the assessment time points is allowed in 
case of measurements 4 and 12 hours after dosing. 
It will be checked whether the injection site mark is well-maintained during injection site 
assessments. If the pen mark fades, it will be marked again to show clearly the injection site. 
If patients who show injection site reactions are discharged, they will be separately guided to 
maintain their injection site marks. 
Erythema and edema among the local reactions of injection sites will be evaluated 
quantitatively using the Draize scale described below. If an injection site reaction like pain on 
palpation, itching, erythema, edema, induration is observed, it must be recorded as an AE. 
Note, however, that pain during injection is a natural response, so it is not considered an AE. 
Local reactions of the injection sites will be evaluated and recorded by one Investigator using 
the following scale: 

Hanmi Pharmaceutical Co., Ltd. 
HM-GLP2-101 
 
CONFIDENTIAL 
Final 4.2 
Page 59 of 75 
Apr 06, 2020 
Erythema will be evaluated as follows: 
• 0 – No erythema 
• 1 – Very slight erythema (barely perceptible) 
• 2 – Well-defined erythema 
• 3 – Moderate to severe erythema 
• 4 – Severe erythema (beet redness) to slight eschar formations (injuries in depth) 
Edema will be evaluated as follows: 
• 0 – No edema 
• 1 – Very slight edema (barely perceptible) 
• 2 – Slight edema (edges of area well defined by definite raising) 
• 3 – Moderate edema (raised approximately 1 mm) 
• 4 – Severe edema (raised more than 1 mm and extending beyond the area of exposure) 
For the irritation assessment, all irritation events will be documented as AEs. If AEs occur, 
the diameter of affected sites will be measured in centimeters (cm) and the condition of the 
injection sites will be recorded. In case of clinically significant injection site reactions, 
subjects may undergo a dermatological consultation and/or cutaneous biopsies for further 
histological examination of the injection site reaction. 
6.2.6. Immunogenicity Assessments 
Blood for assessment of ADA, anti-PEG and NAb will be collected at the time points 
specified in the Schedule of Assessments (Table 1-1 and 1-2). 
Immunogenicity assessments will be performed when deemed necessary by the Principal 
Investigator or the Sponsor in any of the following cases: 
• When ADA formation is suspected based on PD analysis results 
• When biomarker changes related to drug efficacy are not observed at expected 
pharmacologically effective doses

7. STUDY CONDUCT 
7.1. Screening Visit 
The pre-screening will be performed according to the institution’s SOP using IRB-approved 
recruitment documents. 
Subjects will be fully informed of their responsibilities (in terms of attending the study visits, 
dietary and lifestyle restrictions), of all the procedures expected to be performed in the study, 
the possible risks and benefits of being dosed with HM15912 and their rights while 
participating in the study. They will have the opportunity to ask questions and have time to 
consider participation. If a subject wishes to participate in the study, he/she will be asked to 
sign and date an ICF. Written informed consent will be obtained from all subjects before any 
Screening procedures are performed. 
Subjects will be asked to comply with study precautions and to attend the Screening visit 
fasted apart from water (duration of fast is at least 12 hours). 
Screening tests and Day-1 tests may be conducted again in the judgment of the Investigator. 
Subjects who have screen failed may be allowed to re-screen once at the discretion of the 
Principal Investigator, and they are given a new SID in such case. 
Screening assessments are listed in the Schedule of Assessments (Table 1-1 and 1-2). 
7.2. Admission 
The subjects who successfully complete the Screening visit, meet all the inclusion criteria, do 
not demonstrate any exclusion criteria and comply with the precautions in the protocol will be 
allowed for admission after they complete planned tests at the Outpatient visit on Day-1 and 
are approved to participate in the study following randomization. The inclusion/exclusion 
criteria (applicable for admission only i.e., exclusion criteria 1, 2, 3, 5, 6, 7, 8, 9, 10, 11, 13, 
14, 15, 16, 17, 19, 20, 21, 22, 24, 25, 27, 28, 29, 30, and 31) will be reviewed to confirm 
subject eligibility for admission (refer to Section 4.3). 
7.3. Inpatient Treatment Period 
Administration of the IP will be on Day 1, and safety monitoring and serial blood sampling 
for PK and PD assessments will be conducted throughout the inpatient assessment period 
(from Day-1 to Day 7). 
7.4. Outpatient Visits 
Outpatient visits will be on Day 8 (± 4 hours), Day 10 (± 1 day), Day 17 (± 1 day) and Day 30 
(± 3 days) with safety, PK and PD assessments. An additional Outpatient visit may be 
included in later cohorts, if required, after PK data are evaluated. In this case, the additional 
Outpatient visit will proceed after approval from the MFDS and the IRB. 
7.5. Follow-up 
The Follow-up visit will occur on Day 44 (± 3 days) of the clinical study.

7.6. Termination Visit 
Subjects who withdraw consent or are withdrawn from the clinical study should, if possible, 
have a termination visit. This visit should take place as soon as possible after the subject 
withdrew consent or was withdrawn from the clinical study. For patients who have been 
dosed with the IP, they will make a termination visit within 30 days after the administration, if 
possible. The assessments and procedures scheduled for the Follow-up visit should be 
performed at the termination visit. 
7.7. Restrictions 
7.7.1. Dietary and Fluid Restrictions 
Subjects will be required to fast from all food or drink (except water) for at least 12 hours 
before admission, Outpatient and Follow-up visits. 
During the in-house stay at the institution, only meals and fluid provided by the institution 
will be allowed. 
Food will not be allowed within 10 hours before dosing and for approximately 4 hours after 
dosing. Water consumption will also be limited for 1 hour before dosing and for 
approximately 2 hours after dosing.  
Breakfast, lunch and dinner will be served daily, except on Day 1 and admission and 
discharge days. On Day 1 (IP dosing day), subjects will not receive breakfast; lunch will be 
served after 4-hour postdose assessments/collections are performed. 
Breakfast will be served after fasting samples are collected on Day 2 through Day 7. 
No food or drink containing grapefruit, pomelo or Seville orange (including marmalade) will 
be allowed within 48 hours before admission and while subjects are confined to the 
institution. 
Quinine-containing products (e.g., tonic water) will not be allowed within 7 days before 
admission and while subjects are confined to the institution. 
7.7.2. Alcohol and Caffeine 
Consumption of any alcoholic foods, medications, and drinks must be avoided within 48 
hours before any study visit except the Screening visit and while subjects are confined to the 
institution. Subjects should not consume more than 3 units per day during the off-site days 
during the study (1 unit is equal to approximately ½ pint [250 mL] of beer, 1 small glass [125 
mL] of wine, 1 measure [25 mL] of spirits, or 250ml of Korean rice wine). 
No food or drink containing caffeine (e.g., chocolate, coffee, tea, cola, Red Bull) will be 
allowed within 24 hours before each study visit except the Screening visit and while subjects 
are confined to the institution. 
7.7.3. Smoking and Tobacco 
Heavy smokers (smoke more than 5 cigarettes per day or equivalent use of any tobacco 
products) are excluded from the clinical study. Subjects must abstain from smoking during the 
confinement period.

Apr 06, 2020 
7.7.4. Activity and Exercise 
Subjects should refrain from carrying out heavy physical training (e.g., long-distance running, 
weight lifting or any physical activity to which the subject is not accustomed) 48 hours before 
admission until the Follow-up visit. Subjects should neither start any new physical training 
nor increase the intensity of their usual training during study participation. Subjects may 
participate in light recreational activities during studies (e.g., watch television, play computer 
games, read). 
7.7.5. Other Restrictions 
Subjects must neither donate whole blood within 60 days before the Screening visit nor 
participate in apheresis nor get injected with blood products within 1 month before the 
Screening visit, and they must be guided not to donate blood or plasma > 400 mL for at least 
3 months after completion of the clinical study. 
Male subjects must not donate sperm for at least 60 days after receiving the dose of the IP. 
Female subjects must not donate eggs or breastfeed for at least 60 days after receiving the 
dose of the IP. 
To prevent a female partner of a male subject exposed to the IP from getting pregnant or 
getting exposed to his semen, he must be surgically sterile (at least 1-year post vasectomy), 
abstinent or if engaged in sexual relations with women of child-bearing potential, the subject 
and his partner must be using effective or medically recognized dual protection contraceptive 
methods from the administration of IP to up to 60 days after receiving the dose of the IP. 
• Effective contraceptive method: Sexual partner's surgical sterilization (e.g., bilateral tubal 
occlusion, hysterectomy, bilateral salpingectomy, bilateral oophorectomy), intrauterine 
contraception/device of the sexual partner 
• Dual protection contraceptive method: Combinational use of physical barrier methods 
(male condom, female condom and diaphragm for the sexual partner, sponge, cervical 
cap), spermicide for females in the form of foam/gel/film/cream/suppository, oral or 
hormonal contraceptives for the sexual partner 
The adequacy of other methods of contraception will be assessed on a case-by-case basis by 
the Principal Investigator. 
All female subjects participating in this study must not have any possibility of being pregnant. 
Having no possibility of being pregnant is defined as being surgically sterile (e.g., bilateral 
tubal occlusion, hysterectomy, bilateral salpingectomy, bilateral oophorectomy), or being 
menopausal. For females who went through uterus removal or became surgically sterile, the 
institution will try to obtain medical records and document their sterile state. Note, however, 
that having no such records is not a requirement for excluding the subjects from the study. 
Serum or urine pregnancy tests will be conducted for all female subjects. Being post-
menopausal is defined as being amenorrheic for more than 12 months before the Screening 
visit and having an FSH level exceeding 40 U/mL.

7.8. 
Handling of Hypersensitivity Reactions 
7.8.1. Anaphylaxis 
Anaphylaxis, a rapid and serious allergic reaction all over the body, is a life-threatening acute 
immunoreaction. 
If any symptoms suggesting anaphylaxis shock (functional impairment of periphery organs, 
allergic reactions in skin-mucous membrane tissues, etc. due to worsening respiratory 
symptoms, decreased respiration or low-blood pressure) are observed within minutes after IP 
administration, IP administration must be stopped immediately. The subject will then be laid 
and stabilized with his/her legs in the air to prevent further problems from dyspnoea or 
vomiting. IP administration will be immediately stopped. 
If it is confirmed that the symptoms resulted from anaphylaxis, an intramuscular injection of 
epinephrine will be performed. The Investigator may also conduct clinical laboratory tests, 
such as serum tryptase, to screen for anaphylaxis in his/her judgment. Respiratory treatments, 
such as oxygen supply, or low-blood pressure/shock treatments, such as IV drips, may be 
performed when necessary. Monitoring of blood pressure, pulse, respiration, and oxygen 
saturation may also be done. 
7.8.2. Subacute Hypersensitivity Reactions (Type III Hypersensitivity Reactions) 
Type III hypersensitivity reactions are defined as subacute hypersensitivity reactions caused 
by the immune-complex of an antigen and an antibody, which induce arthralgia, skin rash, 
and pruritus accompanying myalgia and fever.  
If symptoms (arthralgia, skin rash, and pruritus accompanied by myalgia and fever, etc.) 
suggesting delayed hypersensitivity reactions are confirmed within a few weeks after IP 
administration, the IP administration will be immediately stopped. The Principal Investigator 
may perform clinical laboratory tests necessary for differential diagnosis.  
If the symptoms are confirmed to have been caused by delayed hypersensitivity reactions due 
to the IP administration, medical treatment will be carried out depending on the subject’s 
condition with the judgment of the Principal Investigator. Any medical products may be used 
to ease the symptoms when necessary, and the Principal Investigator may allow 
administration of steroids, etc.

detailed methods for the analyses outlined below. Any deviations from the planned analyses 
will be described and justified in the clinical study report. 
8.1. Definition of Analysis Populations 
Prior to unblinding, analysis populations will be defined through blinded data review. 
In this clinical study, the PK population is subject to PK assessments whereas the PD 
population is subject to PD assessments. The safety population is subject to all other analyses 
unless described otherwise. Each analysis population is included in the analyses, based on the 
actually administered IP and dosage. 
Safety population: All randomized subjects who received at least 1 dose of the IP 
PK population: All randomized subjects with at least one quantifiable HM15912 
concentration 
PD population: All randomized subjects who received at least 1 dose of the IP 
8.2. General Considerations 
Continuous data will be summarized using descriptive statistics (number, mean, standard 
deviation [SD], minimum, median and maximum). Where appropriate, change from baseline 
will also be summarized. Categorical data will provide the number of subjects and percentage 
by category. All summarized data will be presented by dose level, and the subjects 
administered with placebo will be analyzed as a separate pooled group. Individual subject 
data used for the analysis will be listed by analysis item. 
8.3. Subject Disposition 
Subject disposition will be summarized into the numbers and percentages of subjects dosed 
after randomization, subjects included in each analysis population, subjects completing the 
study, subjects who were withdrawn (including reasons for withdrawal) and subjects who 
have seriously violated the protocol.

administration and dosage, etc. 
8.7. Safety Analyses 
8.7.1. Adverse Events 
Summarization and analysis of AEs will be conducted for treatment emergent adverse events 
(TEAE). TEAEs are defined as AEs that did not exist before IP administration but occurred 
after IP administration, or AEs that worsened after IP administration even if they existed 
before IP administration. 
The reported AEs will be coded according to the SOC and PT of MedDRA, and the number 
of subjects and percentage for AEs after IP administration, AEs related to the IP, SAEs, 
severe AEs, AEs that caused study withdrawal, and AEs coded for injection site reactions will 
be provided. 
All AEs, SAEs, AEs that caused study withdrawal, and injection site reactions will be listed 
by subject. 
8.7.2. Clinical Laboratory Tests 
Clinical laboratory test results will provide descriptive statistics for each category and 
collection time point, and change of clinical significance from baseline will be presented as a 
shift table.

8.7.5. Immune Response Assessments 
When an immunogenicity test was conducted, it will be summarized into the number of 
subjects and percentage according to the results (ADA, anti-PEG, NAb). 
8.7.6. Physical Examinations 
Abnormal physical examination findings will be listed. 
8.7.7. Injection Site Assessments 
All injection site reactions will be documented as AEs and included in AE analysis. 
8.8. Pharmacokinetics Analyses 
PK parameters will be summarized by using descriptive statistics, and concentration-time data 
will be summarized descriptively with tables and graphs by dose level (linear and log scale). 
The noncompartmental PK parameters listed in Section 3.2.2 will be calculated using R, SAS, 
or Phoenix® WinNonlin®. 
Dose proportionality will be evaluated using the linear regression approach for the log-
transformed PK parameters AUC0-t, AUCinf, Cmax values and the log-transformed dose value. 
Graphical presentation of dose proportionality will also be provided. Additional analyses will 
be performed as deemed necessary upon review of the data as exploratory analyses. 
8.9. Pharmacodynamics Analyses 
Descriptive statistics by collection time point for PD parameters will be provided, and the 
PK/PD relationship between IP exposure and PD endpoints will be analyzed by graphical 
displays or by PK/PD modelling, as applicable. 
8.10. Interim Analyses 
No formal interim analysis is planned. However, available blinded safety and tolerability 
(including PK/PD data if available) from each cohort (Day-1 to Day 17) will be evaluated in a 
dose escalation review meeting by the Principal Investigator and the Sponsor. The data review 
will take place before dose escalation can proceed. Screening for the next cohort may be 
conducted even before proceeding to the next cohort is determined, but the IP should be 
administered after proceeding to the next cohort is determined.

8.11. Determination of Sample Size 
Enrolling 8 subjects per cohort (HM15912:placebo=6:2) has been set based on the experience 
and the general properties of exploratory studies, and this matches the typical sample size 
used in similar studies conducted to assess safety and PK. Therefore, no formal sample size 
calculation has been performed. Safety and tolerability of the IP will be assessed based on 
AEs, clinical laboratory parameters, physical examinations, vital signs and ECG parameters 
throughout the duration of the study. Safety analysis will involve examination of descriptive 
statistics and individual subject listings for any effects of study treatment on clinical 
tolerability and safety.

9. DATA MANAGEMENT 
9.1. Data Management 
Details of data management will be described in the Data Management Plan (DMP). 
AEs and medical history will be coded using the current version of MedDRA. Concomitant 
medications will be coded using the medication dictionary of the WHO. 
Serial numbers will be used to identify subjects and their biological data. Subjects' 
information will be encrypted or deleted in all published data and publications according to 
regulations of regions/countries to protect their identity. 
The information on subjects who failed the Screening will also be added to the database. 
The laboratory data of the central laboratory will be electronically transmitted for database 
reconciliation. Electronic laboratory data will be considered source data. If sensitive data 
other than PK data are transmitted to an unsecured network, the data will be encrypted before 
transmission. 
9.2. Electronic Case Report Form 
9.2.1. Process of Clinical Data Management 
The development, maintenance and data management of eCRFs will be performed by the 
contract research organization (CRO) designated by Hanmi Pharmaceutical Co., Ltd. The data 
manager will describe the data management process in the DMP. After data input, the monitor 
will verify data by comparing the source data and the eCRF. Queries may be created to clarify 
the input data. The Principal Investigator will sign electronically the eCRF after all data are 
input, all queries are solved, and the reconciliation of external data is completed. If queries 
need to be revised after the Principal Investigator's approval, the Principal Investigator will 
sign again the data affected by the change. Database lock may be conducted when the 
Principal Investigator's approval is completed. 
9.2.2. Data Input in eCRF 
The data required for safety assessments and analyses for subjects will be input in source 
documents through the eCRF. Data input will be described according to the Completion 
Guideline developed by the CRO designated by Hanmi Pharmaceutical Co., Ltd. All 
personnel who input data in the eCRF will be trained before accessing the study database.

Queries may be automatically created in the eCRF system during data input, and the data 
management personnel, monitor, or data reviewer may create queries manually. Only the 
specific personnel will be authorized to modify the eCRF. The monitor will train the 
personnel. Data modification (revising existing data, adding new data, or deleting data) will 
be directly performed in the eCRF, and all data modifications will be saved in the electronic 
audit trail. 
9.2.4. eCRF Data Approval of the Principal Investigator 
The Investigator or the personnel with investigator authorization will check if all information 
in source data matches the eCRF data and if it is accurately reflected. The Investigator will 
confirm that the information is complete and accurate by signing the eCRF electronically. 
9.3. Document Storage 
All records created under the Principal Investigator's supervision will be maintained 
according to the supervision authorities' guidelines and the GCP guideline when the study is 
completed. Clinical study documents will be stored for at least 3 years after the study is 
completed or for the period indicated in the local regulation and the applicable regulatory 
authorities' guideline, whichever is longer (up to 25 years).

this clinical trial. However, the responsibility for accuracy, integrity and reliability of study 
data provided to the Sponsor will be taken by the Principal Investigator who creates such data. 
The Sponsor can conduct audits as part of quality assurance activities to ensure that the 
clinical trial is performed in accordance with the protocol, SOP, GCP and all related 
regulations. The Sponsor will conduct an institution visit to verify the qualifications of the 
Principal Investigator, to inspect the facilities and to inform the Principal Investigator of 
responsibilities and procedures that will ensure appropriate and accurate documentation. 
Audits will be carried out independently apart from routine monitoring and quality control 
activities. 
Monitoring will be performed to ensure that the study is conducted and documented according 
to the protocol, GCP and all related regulations. The institution will be visited at an 
appropriate time during the study. The monitor must have direct access to source documents 
to check consistency of the data recorded in eCRFs. 
The Principal Investigator must prepare and maintain adequate and accurate records on all 
observations and other data pertinent to the clinical study for each subject. The Principal 
Investigator will allow monitoring of source documents, medical records and source data 
required for completion of eCRFs. Frequent communication between the institution and the 
Sponsor is essential to ensure that the safety of the study is monitored adequately. The 
Principal Investigator will cooperate closely with the monitor and provide appropriate 
evidence that the clinical study is performed according to related regulations and the GCP 
guideline, when necessary. The Principal Investigator will make all appropriate safety 
assessments on an ongoing basis. The Responsible Medical Expert of the Sponsor may review 
safety information as it becomes available throughout the study. 
All aspects of the study will be carefully monitored with respect to Good Clinical Practice 
(GCP) and SOPs for compliance with applicable government regulations. The monitor will be 
an authorized individual designated by the Sponsor. The monitor will have access to all 
records necessary to ensure integrity of the data and will periodically review the progress of 
the study with the Principal Investigator. 
10.2. Subject Safety Assurance 
The Investigator must be sufficiently aware of the AEs and precautions described in this 
protocol in advance to ensure subject safety, and he/she must enable subjects to receive 
appropriate medical treatment for all AEs (including clinically significant laboratory findings) 
occurring during or after the study. If medical treatment is needed for concurrent diseases of 
subjects, the Investigator must let the subject know the fact as rapidly as possible. If SAEs or 
other events occur during the study, they must be reported immediately to the IRB and Hanmi 
Pharmaceutical Co., Ltd. 
The institution must be perfectly prepared to conduct the study appropriately with necessary 
equipment and professional personnel. 
The Sponsor will review all AEs and new information related to the IP and regularly share 
them with the Principal Investigator to ensure subject safety. In addition, the Sponsor will

prepare compensation measures in case of possible damage of subjects and get the 
Investigator to fully understand compensation subjects and procedures and to guide subjects 
about them. 
10.3. Finance and Insurance 
Financial issues of the clinical study will be described in a separate contract. The Sponsor will 
provide insurance for the clinical study as required by national regulations. 
10.4. Access to Source Data/Documents 
An electronic data capture system will be used to manage data collection during this trial. The 
electronic data capture system is a software tool designed to ensure quality assurance and 
facilitate data capture during clinical trials. This system complies with all related regulations 
including GCP of Korea's Pharmaceutical Affairs Act (Article 30, Clause 1, attached Table 4). 
The Principal Investigator will ensure the accuracy, completeness and timeliness of the data 
reported to the Sponsor. Data collection processes and procedures will be reviewed and 
validated to ensure completeness, accuracy, reliability and consistency. A complete audit trail 
will be maintained for all data changes. The Principal Investigator or designee will cooperate 
with the Sponsor’s representative(s) for periodic review of study documents to ensure the 
accuracy and completeness of the data capture system at each scheduled monitoring visit. 
Electronic consistency checks and manual review will be used to identify any errors or 
inconsistencies in the data. This information will be provided to each institution by means of 
electronic or manual queries. 
The Principal Investigator or designee will prepare and maintain adequate and accurate study 
documents (medical records, ECG, AE and concomitant medication reporting, raw data 
collection forms, etc.) designed to record all observations and other pertinent data for each 
subject receiving the IP. Originals of source documents will be stored, but copies that are 
clearly recorded identically to originals along with signatures of persons who copied and dates 
will also be considered as source documents. 
The Principal Investigator will allow Sponsor representatives, contract designees, authorized 
regulatory authority inspectors and the IRB to have direct access to all documents pertaining

and the Principal Investigator abide by the principles of the ICH guidelines on GCP. The 
clinical study will also be carried out in keeping with national and local legal requirements. 
10.7. Informed Consent 
Before each subject is enrolled in the clinical study, written informed consent will be obtained 
from the subject according to the regulatory and legal requirements of the participating 
country. As part of this procedure, the Principal Investigator or Investigator must explain to 
groups of subjects or individual subjects the IRB-approved ICF orally and in writing with 
regard to the nature, duration and purpose of the study and the action of the drug in such a 
manner that the subject is aware of potential risks, inconveniences or AEs that may occur. The 
subject is allowed to review study information and ask questions through one-on-one 
interviews in a separate room. The subject should be informed that he/she is free to withdraw 
from the study at any time. He/she will receive all information that is required by relevant 
regulations and ICH guidelines.  
The ICF must be signed and dated including time; 1 copy will be handed to the subject, and 
the Principal Investigator will retain 1 original as part of clinical study records. The Principal 
Investigator will not undertake any investigation specifically required for the clinical study 
until written consent has been obtained. The terms of consent and date and time when it was 
obtained must also be documented. 
If a protocol amendment is required, then the ICF may need to be revised to reflect the 
changes to the protocol. If the ICF is revised, it must be reviewed and approved by the 
responsible IRB, and signed by all subjects subsequently enrolled in the clinical study as well 
as those currently enrolled in the clinical study.

10.8. Protocol Approval and Amendment(s) 
Before the start of the clinical study, the clinical study protocol and other relevant documents 
will be approved by the IRB in accordance with local legal requirements. The Sponsor must 
ensure that the clinical study will proceed ethically and legally before the first subject is 
enrolled in the study. 
This protocol is to be followed exactly. To alter the protocol, amendments must be written, 
which must be released by the responsible staff and receive IRB approval prior to 
implementation (as appropriate). 
Administrative changes may be made without the need for a formal amendment, but will also 
be mentioned in the integrated clinical study report. All amendments will be distributed to all 
study protocol recipients, with appropriate instructions. 
10.9. Confidentiality Data Protection 
All clinical study findings and documents will be regarded as confidential. The study staffs 
participating in the study, the MFDS, the Sponsor, clinical study inspectors, monitors, and the 
IRB and the Human Research Protection Center of the institution will be allowed to access 
study-related documents under the condition that they ensure confidentiality of subjects. 
Study documents (protocols, IBs, and other materials) will be stored appropriately in areas 
with a locking device to ensure their confidentiality. The Principal Investigator and members 
of his/her research team (including the IRB) must not disclose such information without prior 
written approval from the Sponsor, except to the extent necessary to obtain informed consent 
from subjects who wish to participate in the trial or to comply with regulatory requirements. 
The anonymity of participating subjects must be maintained. Subjects will be specified in 
study documents by their subject number or initial, not by name. Documents that identify 
subjects (e.g., signed ICF) must be maintained in confidence by the Principal Investigator. 
10.10. Publication Policy 
By signing the clinical study protocol, the Principal Investigator agrees with the use of results 
of the clinical study for the purposes of national and international registration, publication and 
information for medical and pharmaceutical professionals. If necessary, the regulatory 
authorities will be notified of the Principal Investigator’s name, address, qualifications and 
extent of involvement. 
The Principal Investigator shall not publish any data (poster, abstract, paper, etc.) without 
having consulted with the Sponsor in advance.
