• 
Rationale for Calculation of the Number of Subjects 
The purpose of the study is exploratory which is not to verify statistical hypotheses, and in 
the case of Phase 1 clinical studies being conducted using new drugs for which safety is not 
established, it is ethically desirable to conduct the study in the minimum number of subjects 
while satisfying the study objectives. In addition, dose groups had a certain ratio of subjects 
who will receive the placebo to enable double-blind for an objective safety and tolerability 
review. In this study, for the low dose groups (Groups 1 and 2), the sentinel dose groups, the 
target number of subjects per dose group has been set to 4 subjects per dose group, and the 
target number of subjects for other dose groups has been set to 8 subjects per dose group.

Analytical 
Procedure  
This is a Phase 1, dose blocked-randomized, double-blind, placebo controlled, single dosing, 
dose-escalation study to investigate the safety, tolerability, pharmacokinetic characteristics 
of hzVSF-v13 after intravenous administration in healthy male subjects.  
 
Each dose group will have hzVSF-v13 and the placebo randomized at a 3:1 ratio to conduct 
the clinical study. The study will be proceeded sequentially from the lowest dose, and 
whether to proceed with the next dose will be determined based on the tolerability and safety 
results of the previous dose.  
Each subject in Group 1 and Group 2 will be administered, and if no significant dose-limiting 
toxicity (DLT) occurs within 72 hours, the next subject will be administered.  
In the case of all dose groups except for Group 1 and Group 2 (Group 3–Group 8), 3 out of 
8 subjects in each dose group (2 subjects for the study drug and 1 subject for the placebo) 
will receive the investigational product (hzVSF-v13 or placebo) at least 72 hours earlier than 
the remaining subjects in the same dose group. If no significant dose-limiting toxicity occurs 
within 72 hours, the remaining subjects in the relevant dose group will receive the 
investigational product (hzVSF-v13 or placebo) depending on the randomization.  
 
In the case that at least 3 subjects experience a Grade 3 adverse event or at least 1 subject in 
certain dose groups experience a Grade 4 adverse event based on the Common Terminology

Criteria for Adverse Events (CTCAE) published by the United States National Cancer 
Institute (NCI), the principal investigator shall consult the Safety Monitoring Committee 
(SMC) and discuss discontinuation of the relevant dose group and dose escalation with the 
sponsor. (For Group 1 and Group 2, discontinuation of the dose group and dose escalation 
shall be considered based on the following criterion: occurrence of Grade 3 adverse event in 
at least 2 subjects or Grade 4 adverse event in at least 1 subject.) 
 
The screening tests shall only be performed in volunteers within 4 weeks prior to the first 
day (1 d) of investigational product administration (−28 d to −2 d) in order to select the 
subjects considered to be eligible for this clinical study. 
 
 Single-Dose Study (Intravenous Administration) 
- 10 mg, 20 mg, 50 mg, 100 mg, 200 mg, 400 mg, 800 mg, 1,200 mg IV  
 
The selected subjects will be admitted to the Seoul National University Hospital Clinical 
Trials Center 2 days (-2d) prior to administration of the investigational product. The skin 
test will be performed a day (-1d) prior to administration of the investigational product. Only 
the subjects who did not have clinically significant findings in the skin test will have 
intravenous (IV) administration of the investigational product (hzVSF-v13 or placebo) at 9 
a.m. on the day (1d) of investigational product administration . The subjects will be required 
to perform the clinical study procedures in accordance with the predefined schedule and will 
be discharged 7 days (8d) after the administration. Thereafter, the subjects will visit the 
Seoul National University Hospital Clinical Trial Center as outpatients from 9 d to 92 d in 
order to perform the clinical study procedures according to the predefined schedule. After 
completing all scheduled tests up to 15 d for each dose group, an independent SMC, 
established separately from this study, will evaluate the safety-related data. With reference 
to the evaluation result of the SMC, the principal investigator and the sponsor will decide

5. BACKGROUND OF THE CLINICAL STUDY 
5.1. DETAILS OF THE DEVELOPMENT 
Cells isolated from the spleen of mice infected with EMC virus were fused with cancer cells to obtain 
hybridoma cells, and then screened for substances with antiviral activity from these cells and selected. The 
substances secreted by these cells were named “VSF (virus suppressing factor)” derived from mice, and it 
was confirmed that VSF has antiviral activity against various viruses. Mouse-derived VSF has been 
humanized (hzVSF) with human immunoglobulin IgG4. The in silico method of Lonza was used to receive 
recommendation for thirteen variants of hzVSF-expected to have low immunogenicity. Among these, 
hzVSF-v13 has excellent antiviral activity and is unlikely to act as an immunogen in clinical because it does 
not cause T cell activity according to an in vitro peripheral blood mononuclear cells (PBMC) assay; therefore, 
it has been selected as a candidate substance. In addition, it is intended to be developed as a treatment of 
influenza virus by identifying the antiviral and anti-inflammatory activity in mice, ferrets and beagle dogs 
infected with influenza virus.  
Also, it is intended to be developed as a treatment for hepatitis B and C because it has an excellent function 
to suppress proliferation of hepatitis B virus and hepatitis C virus. 
 
5.2. EFFICACY PHARMACOLOGY TEST 
Mice, ferrets, and beagle dogs were used for non-clinical efficacy evaluation. In the case of mice, 3 to 5 each 
of male and female mice were used for evaluation, and the doses were administered from 0.1 mg/kg to 2 
mg/kg (1,000 U/kg to 20,000 U/kg). In the case of ferrets, 2 female ferrets per group were administered 
intravenously at 0.134 to 8.571 mg/kg 2 times, at 2 days and at 4 days after virus infection. In the case of 
beagle dogs, female dogs were administered a single dose of 0.5 mg/kg intravenously at 2 days after virus 
infection. In all laboratory animals administered, it was confirmed that influenza virus replication was 
suppressed and infiltration of immune cells into the lungs after influenza virus was suppressed by 
administration of hzVSF-v13. In the serum of mice, it was confirmed that the administration of hzVSF-v13 
suppressed the production of inflammatory cytokines and inflammatory mediators.  
In the cell experiment on hepatitis B virus and hepatitis C virus, it was confirmed that the synthesis of genes 
and proteins of not only cccDNA of hepatitis B virus but also viral proteins and 1a, 1b and 2a genotypes of 
hepatitis C virus was inhibited. In addition, in the cell experiment on mouse hepatitis virus which has similar 
pathology to human hepatitis, suppression of virus proliferation as well as suppression of growth,

suppression of inflammation, relief of symptoms and promotion of treatment were confirmed. 
 
5.3. MECHANISM OF ACTION 
hzVSF-v13 acts as a ligand for the mutated vimentin (VSF receptor, VR) that appears on the cell surface 
specifically in cells infected with virus, and it induces antiviral and anti-inflammatory mechanisms of action 
in cells. The binding site of the mutated vimentin to which hzVSF-v13 binds was confirmed, and it was 
confirmed that the antiviral action of hzVSF-v13 was absent in cells that do not express vimentin. In addition, 
in the case of cells expressed by introducing vimentin genes into the cells, antiviral ability against hzVSF-
v13 process after virus infection was restored, whereas in the case of cells expressed by introducing mutated 
vimentin genes that do not bind to hzVSF-v13, cytotoxicity due to virus infection could not be suppressed 
even after hzVSF-v13 processing. Also, as a result of investigating the location in cells by binding 
fluorescence to hzVSF-v13 after virus infection, it was confirmed that hzVSF-v13 bound to mutated 
vimentin in the cell membrane on the cell surface and decomposed in lysosomes through endocytosis. It is 
considered that hzVSF-v13 processing in cells infected with EMC virus induces AKT protein 
phosphorylation which results in suppression of replication of the virus, whereas it inhibits NF-kB 
phosphorylation which results in suppression of inflammation. 
 
5.4. SAFETY PHARMACOLOGY TEST 
Evaluation of the effect on the cardiovascular system of anesthetic and unrestrained dogs by intravenous 
administration of hzVSF-v13: In this test, 4 male anesthetic and unrestrained beagle dogs with a remote 
transmitter inserted were administered the test substance hzVSF-v13 intravenously, and blood pressure and 
heart rate measurement and electrocardiography were performed to evaluate the effect on the cardiovascular 
system.  
Dulbecco’s phosphate buffered saline (DPBS) was an excipient administered as a reference substance for 
the first administration, and 6.25, 25 and 100 mg/kg doses of the test substance was administered for the 
second, third and fourth administration. The same animal received intravenous administration of a single 
dose of each dose at an interval of 1 week. 
Cardiovascular parameters (blood pressure, heart rate and electrocardiogram) were assessed at 0 hours 
before initiation of the administration (pre-dose), and 0.083, 0.25, 0.5, 1, 2, 4, 6 and 24 hours after initiation 
of the administration.  
Blood pressure (systolic, diastolic and mean blood pressure) and heart rate did not show any change by 
administration of 6.25 and 25 mg/kg doses of the test substance. In 1 case after administration of a 100 
mg/kg dose of the test substance, blood pressure decreased and heart rate increased between 0.083 hours 
and 1 hour after initiation of the administration. 
For electrocardiogram parameters (PR, QRS, QT and QTc intervals), the QRS, QT and QTc intervals were 
not influenced by administration of 6.25, 25 and 100 mg/kg doses of the test substance, but in 1 case after 
administration of a 100 mg/kg dose of the test substance, the PR interval showed a shortened trend compared 
to the reference substance administration at 0.25 hours to 2 hours after initiation of the administration. 
Temperature did not show any change by administration of 6.25, 25 and 100 mg/kg doses of the test 
substance. 
As a result of observation of general symptoms, vomiting was observed in 1 case after administration of a

100 mg/kg dose of the test substance. 
From the above results, the test substance hzVSF-v13 was found to have no cardiovascular effect at 6.25 
and 25 mg/kg doses when a single dose was administered intravenously to beagle dogs under this test 
condition. Decreased blood pressure, increased heart rate, and shortened PR interval were observed due to 
the effect of test substance administration in 1 case after administration of a 100 mg/kg dose, but they 
recovered within 24 hours after initiation of the administration. 
 
5.5. PHARMACOKINETIC TEST 
The concentration of hzVSF-v13 in the plasma was measured after intravenous administration of a single 
dose to mice in order to calculate toxicokinetic parameters. In the case of the systemic exposure level of 
hzVSF-v13, AUC was 78.8 g•day/mL to 6,839.9 g•day/mL, Cmax was 5.2 g/mL to 563.0 g/mL, and t1/2 
was 8.9 to 10.1 days in male mice. In female mice, AUC was 113.0 g•day/mL to 8,686.9 g•day/mL, Cmax 
was 5.5 g/mL to 607.2 g/mL, and t1/2 was 10.2 to 13.4 days.  
After intramuscular administration of a single dose of hzVSF to mice, they had a 6-week observation period. 
The administration concentrations were 0.2 mg/kg, 0.8 mg/kg and 3.2 mg/kg, blood samples were collected 
at 1, 2, 4, 7, 14, 21, 28 and 42 days during the observation period to measure the concentration of hzVSF in 
the plasma in order to calculate toxicokinetic parameters. In the case of the systemic exposure level of 
hzVSF-v13, AUC was 35.7 kg•day/mL to 906.7 kg•day/mL, Cmax was 3.5 mg/mL to 60.7 mg/mL, and t1/2 
was 6.4 to 8.0 days in male mice. In female mice, AUC was 32.4 kg•day/mL to 859.5 kg•day/mL, Cmax was 
3.6 mg/mL to 61.6 mg/mL, and t1/2 was 4.6 to 6.5 days. An increase in the blood concentration was observed 
in higher administration doses, and a decrease in the blood concentration was observed for the 6-week 
observation period thereafter. The systemic exposure level (Cmax) increased at a ratio similar to the increase 
in administration dose, and it was determined that there was not much difference between the gender. In 
addition, cases of death and abnormal general symptoms were not observed. 
As a result of measuring the concentration of hzVSF-v13 in the plasma after intravenous administration to 
rats for 2 week at 3 doses per week, 6 doses in total, and calculating toxicokinetic parameters, Tmax was 14 
to 14.02 days. For the systemic exposure level of hzVSF, the AUCall and Cmax were 4,095 ng•hr/mL to 59,151 
ng•hr/mL and 307 ng/mL to 5,190 ng/mL in female animals. The AUCall and Cmax were 3,679 ng•hr/mL to 
72,727 ng•hr/mL and 238 ng/mL to 6,153 ng/mL in female animals. In rats, the blood collection days in the 
2-week administration period (administered 6 doses in total; administration days: Days 1, 3, 6, 9, 11 and 14) 
were Days 1, 6, 11, and 14, and an increase in the blood concentration was observed as the number of doses 
administered increased at all doses. The highest concentration was observed after the administration (0.5 hr) 
at the final administration day (Day 14) (excluding male low-dose group), and a decrease in the blood 
concentration was observed during the following 6-week observation period. The systemic exposure level 
(AUCall, Cmax) increased at a ratio similar to the increase in administration dose, and it is determined that 
there was no difference between the gender. 
As a result of measuring the concentration of hzVSF-v13 in the plasma after intravenous administration to 
beagle dogs for 2 week at 3 doses per week, 6 doses in total, and calculating toxicokinetic parameters, Tmax 
was 11.0 to 16.0 days. For the systemic exposure level of hzVSF-v13, the AUCall and Cmax were 2,842.1 
g•hr/mL to 62,769.4 g•hr/mL and 276.0 g/mL to 4,090.0 g/mL in male animals. The AUCall and Cmax 
were 2,727.7 g•hr/mL to 57,247.4 g•hr/mL and 229.0 g/mL to 4,180.0 g/mL in female animals. In 
beagle dogs, the systemic exposure level (AUCall, Cmax) of the test substance hzVSF increased at a ratio 
similar to the increase in administration dose, and it increased according to the increase in the number of 
doses administered at all doses. The highest blood concentration (Tmax) was observed at Day 11 (5th 
administration) in male animals in the 6.25 and 100 mg/kg treatment groups and female animals in the 6.25

and 25 mg/kg treatment groups, and at Day 14 (6th administration) and at 0.5 hr after the administration in 
male animals in the 25 mg/kg treatment group and female animals in the 100 mg/kg treatment group. Based 
on the results of analyses performed subsequently at every week up to weeks 3 to 8 (blood collection days: 
Days 22, 29, 36, 43, 50 and 57), blood concentration gradually decreased, and the test substance was detected 
up to week 8 in 1/2 male cases and up to week 7 in 1/2 female cases in the 100 mg/kg treatment group. In 
addition, differences between females and males were not observed. In addition, the half-life (t1/2) after 
administering 6 doses for 2 weeks was 16.5 to 22.6 days at all doses in male and female animals. 
 
5.6. TOXICITY TEST 
- Single-dose toxicity test 
• Single-intravenous-dose toxicity test of hzVSF-v13 using rats: This test was performed to evaluate the 
toxicity after intravenous administration of a single dose of the test substance hzVSF-v13 to 6-week-old 
male and female Sprague-Dawley rats, and to estimate the approximate lethal dose. The study was composed 
of 2 groups—a group treated with the test substance at a dose of 100 mg/kg and a control group (DPBS)—
and a single dose was administered intravenously to 5 male and female animals respectively. For 14 days 
after the administration, general symptoms were observed and body weight was measured. Once the 
observation period was over, the animals were euthanized, and necropsy was performed. Cases of death 
were not observed in male and female animals in the 100 mg/kg treatment group. In addition, the effects of 
administration of the test substance on general symptoms, weight measurements, and necropsies were not 
recognized. Based on the results of intravenous administration of a single dose of hzVSF-v13 to rats under 
the conditions of this test, the approximate lethal dose has been determined to exceed 100 mg/kg in both 
male and female animals. 
• Single-intramuscular-dose toxicity test of hzVSF-v13 using rats: This test was performed to evaluate the 
toxicity after intramuscular administration of a single dose of the test substance hzVSF-v13 to 6-week-old 
male and female Sprague-Dawley rats, and to estimate the approximate lethal dose. The study was composed 
of a group treated with the test substance at a dose of 80 mg/kg and a control group (DPBS), and a single 
dose was administered intramuscularly to 5 male and female animals respectively. For 14 days after the 
administration, general symptoms were observed and body weight was measured. Once the observation 
period was over, the animals were euthanized, and necropsy was performed. Cases of death and abnormal 
general symptoms were not observed in male and female animals in the 80 mg/kg treatment group. The 
effects of administration of the test substance on weight measurements and necropsies were not recognized. 
Based on the results of intramuscular administration of a single dose of hzVSF-v13 to rats under the 
conditions of this test, the approximate lethal dose has been determined to exceed 80 mg/kg in both male 
and female animals. 
- Repeat-dose toxicity test 
• The results of 4-week repeat-dose and 4-week recovery tests in rats were as follows. This test was 
performed to evaluate the toxic responses and safety observed in necropsies performed 2 weeks after 
the final administration of the repeated intravenous administration of hzVSF-v13 to male and female 
Sprague-Dawley (Crl: CD [SD]) rats 3 times weekly for 2 weeks—6 times in total—and to set a 4-
week recovery group and evaluate the reversibility of toxic changes. The test substance was 
administered intravenously at 3 doses—6.25, 25 and 100 mg/kg—to 10, 10 and 15 each of male and 
female animals in each group 6 times in total for 2 weeks. A control group (DPBS) was set as well, 
and intravenous administration was given to 15 animals 6 times in total for 2 weeks. A 4-week recovery 
period was scheduled from 2 weeks after the final administration in order to evaluate the reversibility 
of toxicity in 5 each of male and female animals in the control group and 100 mg/kg treatment group.

In addition, a toxicokinetic test group was set, and 3 each of male and female animals in each group 
were analyzed at each time point of blood collection. General symptom observation, body weight 
measurement, feed intake measurement, functional test (only applicable to the main test group), 
ophthalmologic examination, and urinalysis were performed during the observation period, and 
hematology, blood biochemistry, organ weight measurement, visual inspection at necropsy, and 
histopathological examination were performed after the end of the observation period. The systemic 
exposure level of the drug was confirmed as well through a toxicokinetic test. No effect of 
administration of the test substance on the general symptoms, weight, feed intake, ophthalmologic 
examination, urinalysis, hematology, blood biochemistry, organ weight, and necropsy was observed 
in male and female animals in the 6.25, 25 and 100 mg/kg treatment groups. As a result of the 
histopathological examination, no effect of administration of the test substance was observed in male 
and female animals in the 100 mg/kg treatment group. In addition, it was determined that there was 
local tolerance because evidence of myofiber damage was not observed at the administration site of 
male and female animals in the 6.25, 25 and 100 mg/kg treatment groups. During the 2-week 
administration period, an increase in the blood concentration was observed as the number of doses 
administered increased at all doses. The highest concentration was observed after the administration 
(0.5 hr) at the final administration day (Day 14) (excluding male low-dose group), and a decrease in 
the blood concentration was observed during the following 6-week observation period. The systemic 
exposure level (AUCall, Cmax) increased at a ratio similar to the increase in administration dose, and it 
is determined that there was no difference between the gender. As described above, based on the results 
of repeated intravenous administration of the test substance hzVSF-v13 to rats 3 times weekly for 2 
weeks—6 times in total—under the conditions of this test, the no-observed-adverse-effect level 
(NOAEL) has been determined to be not less than 100 mg/kg in both male and female animals. 
• 
The results of 4-week repeat-dose and 4-week recovery tests in beagle dogs were as follows. This test 
was performed to evaluate the toxic responses and safety observed in necropsies performed 2 weeks after 
the final administration of the repeated intravenous administration of the test substance hzVSF-v13 at 
doses of 0 (control group), 6.25, 25 and 100 mg/kg 3 times weekly for 2 weeks using 3 each of male and 
female beagle dogs per group. Furthermore, starting from 2 weeks after the final administration, a 4-
week recovery group composed of 2 each of male and female animals was set in the control group and 
the high-dose group to check the reversibility of the toxic changes. Also, a toxicokinetic test was 
performed to evaluate the systemic exposure level of the drug. Animal deaths did not occur in male and 
female animals in all test groups during the test period. However, symptoms deemed to be 
hypersensitivity reactions, such as hypoactivity, vomiting, paleness, or hyperemia, were observed after 
the 4th to 6th administrations in male and female animals in the 100 mg/kg treatment groups, and after 
the 6th administration in the 25 mg/kg treatment group. In the histopathological examination, the size of 
germinal centers of the spleen increased in male and female animals in all test substance treatment groups, 
and this is considered to be due to the immune response of the test substance. No toxicological effect of 
administration of the test substance on the weight, feed intake, eye examination, electrocardiography, 
urinalysis, hematology, blood biochemistry, organ weight, necropsy and local tolerance test was observed. 
In the toxicokinetic test, the systemic exposure level (AUCall, Cmax) of the test substance hzVSF-v13 
increased in proportion to the increase in administration dose, and it increased according to the increase 
in the number of doses administered. The highest blood concentration (Tmax) was observed at Day 11 (5th 
administration) in several treatment groups, and after the administration (at 0.5 hr) at Day 14 (6th 
administration) in several treatment group. Thereafter, the blood concentration gradually decreased from 
Week 3, and no difference was observed between male and female animals. In addition, as a result of 
measuring anti-drug antibodies (ADAs) against hzVSF-v13, it was confirmed that ADAs were produced 
in most of the animals starting from about 11 days after initiating administration of the test substance. 
Due to the results described above, it has been determined that the no-observed-adverse-effect level 
(NOAEL) for male and female beagle dogs under these test conditions is 6.25 mg/kg.

7.3.1. EXPECTED SIDE EFFECTS FROM NON-CLINICAL LABORATORY STUDIES RESULTS 
Since hzVSF-v13 has never been administered to human subjects, there are no known adverse events. Also, 
since there are no similar drugs of the same class targeting vimentin or mutant vimentin, it is not possible to 
predict adverse events based on the adverse event reports of similar drugs. During the observation period in the 
4-week repeat-intravenous-dose toxicity test in beagle dogs, no animal deaths occurred in male and female 
animals in all test groups, and no symptoms were observed until the 3rd administration. However, after the 4th 
and 5th administration (9 and 11 days after initiating the administration), symptoms such as hypoactivity, 
vomiting, paleness, or hyperemia were observed in 2 to 3 out of 5 male animals and 4 out of 5 female animals 
in the 100 mg/kg treatment group. At the 6th administration (14 days after initiating the administration), 
symptoms such as hypoactivity, vomiting, paleness, or hyperemia were observed in all female and male animals 
in the 25 mg/kg treatment group, and 4 out of 5 male animals and 3 out of 5 female animals in the 100 mg/kg 
treatment group. Besides, 1 to 2 cases of soft stool were observed in the control group and 1 each of female 
animals the 6.25 and 25 mg/kg treatment groups, and no symptoms were observed in the recovery group.  
During the observation period in the 4-week repeat-intravenous-dose toxicity test using rats, cases of death and 
abnormal general symptoms were not observed in male and female animals in the 6.25, 25 and 100 mg/kg 
treatment groups during the administration period. Loss of teeth was observed in 1 female animal in the control

9.2. RATIONALE FOR CALCULATION OF THE NUMBER OF SUBJECTS 
The purpose of the study is exploratory which is not to verify statistical hypotheses, and in the case of Phase 
1 clinical studies being conducted using new drugs for which safety is not established, it is ethically desirable 
to conduct the study in the minimum number of subjects while satisfying the study objectives. In addition, 
dose groups had a certain ratio of subjects who will receive the placebo to enable double-blind for an objective 
safety and tolerability review. In this study, for the low dose groups (Groups 1 and 2), the sentinel dose groups, 
the target number of subjects per dose group has been set to 4 subjects per dose group, and the target number 
of subjects for other dose groups has been set to 8 subjects per dose group.

smoking and alcohol consumption will be prohibited from 3 days before the admission until the day of 
discharge. Also, strenuous exercises exceeding activities of daily living will be prohibited and use of 
contraception has to be maintained throughout the clinical study period. In addition, the subjects will be 
required to fast, except for drinking water, after 10 p.m. on the day before the scheduled date of clinical 
laboratory tests, and any external factors that could have an effect on the clinical laboratory tests (drinking, 
smoking, strenuous exercise, etc.) will be restricted if possible prior to the tests even after the discharge. In 
addition, fluid intake is also prohibited from an hour before the administration to 2 hours after the 
administration, and food intake is prohibited for 4 hours after the administration.  
9.6. DROP-OUT AND SUBJECT SUBSTITUTION 
“Enrollment” refers to the randomization (assignment of subject ID) of subjects participating in the study (i.e., 
those who signed the informed consent form) due to their eligibility based on the inclusion/exclusion criteria. 
Incompletion of a study by an enrolled subject is called “drop-out.” The drop-out of a subject may be decided 
at any time during the study period. A subject who applies to one of the situations shown below is processed 
as a dropout, and the date of drop-out, date of the last administration and reason for drop-out have to be recorded 
in a CRF at the moment of drop-out. 
1) In the case that a subject requests discontinuation of the investigational product administration during 
the clinical study, or withdraws his consent to participation in the study 
2) In the case that a subject has received a drug that is expected to affect the evaluation of the safety or 
pharmacokinetics of the study drug during the clinical study 
3) In the case that serious adverse events/adverse drug reactions have occurred 
4) In the case that a subject is unable to perform blood sampling for the testing for pharmacokinetics/safety 
5) In the case that significant protocol violation cases are newly identified during the clinical study 
6) In the case that the sponsor or the Ministry of Food and Drug Safety requests discontinuation 
7) In the case that the principal investigator/investigator determines that the study has to be discontinued 
due to other reasons 
 
This study allows enrollment of a small number of backup subjects in advance considering the drop-out rate 
prior to the initial administration, and a dropped out subject may be substituted with a backup subject in case 
of dropping out prior to the initial administration. In the event of more than 2 subjects in the same dose 
group drop out after administration of the investigational product, substitution of the subjects shall be 
decided after a discussion among the principal investigator, sponsor, pharmacokinetic and statistical analysts. 
The first figure of the substituted subject’s subject number will be 2, and the last 3 figures will be the same 
number as the dropped out subject’s subject number (e.g., if Subject R1104 drops out and is replaced, the 
subject number to be assigned will be R2104). The substituted subject will be assigned to the same dose 
group as the dropped out subject. The test results of the relevant subject may be reviewed in the finally 
evaluable items up until the time of discontinuation/drop-out.

“Completion” in this clinical study refers to the case that the subject meets the inclusion/exclusion criteria 
specified in the protocol and has completed the entire study process and all visits. 
 
9.8. BACKUP SUBJECTS (SUBJECT CANDIDATES) 
This study can recruit backup subjects (subject candidates) for smooth progress. Those who participate as 
backup subjects and have not received the study drug will be sent home after other subjects complete the 
initial administration, and backup subjects may participate in the next treatment group. 
 
10. ANALYTICAL METHOD 
10.1. STUDY DESIGN 
This is a Phase 1, dose blocked-randomized, double-blind, placebo controlled, single dosing, dose-escalation 
study to investigate the safety, tolerability, pharmacokinetic characteristics of hzVSF-v13 after intravenous 
administration in healthy male subjects. Subjects will be randomized to the test group and the control group 
at a 3:1 ratio in each dose groups; however, in the case of all dose groups except for Group 1 and Group 2 
(Group 3–Group 8), the first 3 out of 8 subjects in each dose group will be randomized to be 2 subjects for 
the study drug and 1 subject for the placebo. Collection of adverse events, physical examinations, vital sign, 
electrocardiography (12-lead ECG), clinical laboratory tests, immunogenicity test, etc. will be performed to 
evaluate the safety and tolerability, and blood collection will be carried out to evaluate the pharmacokinetic 
characteristics.

In the homogeneous population of health volunteers with similar demographic characteristics, the effect of 
differences in individual weights on pharmacokinetic characteristics is considered to be insignificant. In 
addition, if the drug is administered at doses depending on body weights or body surface areas, there may be 
difficulties to conduct the study compared to administration at a fixed dose, and there may be difficulties 
compared to administration at a fixed dose even in evaluation of the safety and tolerability. Therefore, the 
administration dose of the investigational product will be a fixed dose. 
The results of beagle dogs, which are the most sensitive species of those applied, have confirmed that the 
maximum no-observed-adverse-effect level (NOAEL) is 6.25 mg/kg. Large molecules (not less than 100,000 
daltons), such as antibodies, are scaled by body weight, not by body surface area [HED (mg/kg) = NOAEL 
(mg/kg)]. In this case, the human equivalent dose (HED) converted into weight of the maximum no-observed-
adverse-effect level (NOAEL) is 6.25 mg/kg, and the maximum recommended starting dose (MRSD), given 
a safety factor of 10, is 37.5 mg, assuming that healthy adult males weigh 60 kg. 
Furthermore, pharmacological effects that suppress viral replication and inflammatory reaction have been

confirmed at 2 mg/kg upon intravenous administration to influenza mouse models. The human equivalent dose 
(HED) of this dose converted into weight that has been scaled by body weight [HED (mg/kg) = NOAEL 
(mg/kg)] is 2 mg/kg, and given a safety factor of 10, it is 12 mg respectively, assuming that healthy adult males 
weigh 60 kg. 
Therefore, the initial administration dose has been determined to be 10 mg taking into account that the weight-
corrected pharmacologically active dose is the smaller dose between the MRSD and the weight-corrected 
pharmacologically active dose.

Considering that the half-life of the study drug in the human body estimated using the allometry method based 
on these is estimated to be approximately 23 to 34 days, the half-life of the study drug is estimated to be 
approximately 30 days. Therefore, the last blood collection time point has been set as 2,184 hours (92 d 0 h). 
Based on these, the pharmacokinetic blood collection time points in the single-dose study have been set as 
follows: 0 h (pre-dose), 0.5, 1, 2, 4, 6, 8, 10, 12, 24, 36, 48, 60, 72, 96, 120, 144, 168, 336 (15 d 0 h), 504 (22

h; post-dose) (26 points).  
Excluding the volunteers who were positive in the immunogenicity test for hzVSF-v13 during the screening 
tests, the blood collection time points in the single-dose study have been set as the time of screening tests, 168 
(8 d 0 h), 336 (15 d 0 h), 672 (29 d 0 h), 1,344 (57 d 0 h), 2,184 h (92 d 0 h; post-dose) (6 points) in order to 
confirm the production of antibodies against hzVSF-v13. 
 
DEFINITION OF DOSE-LIMITING TOXICITY (DLT) 
Dose limiting toxicity (DLT) is hematologic or non-hematologic toxicity related to the investigational product, 
and it is defined as adverse events of at least Grade 3 based on the National Cancer Institute (NCI) - Common 
Terminology Criteria for Adverse Events (CTCAE) version 4.03. 
 
DOSE ESCALATION/DISCONTINUATION CRITERIA 
Each dose group will have hzVSF-v13 and the placebo randomized at a 3:1 ratio to conduct the clinical study. 
The study will be proceeded sequentially from the lowest dose, and whether to proceed with the next dose will

Page No.: 31/51 
be determined based on the tolerability and safety results of the previous dose.  
Each subject in Group 1 and Group 2 will be administered, and if no significant dose-limiting toxicity (DLT) 
occurs within 72 hours, then the next subject will be administered.  
In the case of all dose groups except for Group 1 and Group 2 (Group 3–Group 8), 3 out of 8 subjects in each 
dose group (2 subjects for the study drug and 1 subject for the placebo) will receive the investigational product 
(hzVSF-v13 or placebo) at least 72 hours earlier than the remaining subjects in the same dose group. If no 
significant dose-limiting toxicity occurs within 72 hours, the remaining subjects in the relevant dose group 
will receive the investigational product (hzVSF-v13 or placebo) depending on the randomization.  
In the case that at least 3 subjects experience a Grade 3 adverse event or at least 1 subject in certain dose 
groups experience a Grade 4 adverse event based on the CTCAE published by the United States NCI, the 
principal investigator shall consult the independent SMC, established separately from this study, and discuss 
discontinuation of the relevant dose group and dose escalation with the sponsor. (For Group 1 and Group 2, 
discontinuation of the dose group and dose escalation shall be considered based on the following criterion: 
occurrence of Grade 3 adverse event in at least 2 subjects or Grade 4 adverse event in at least 1 subject.) 
Empirically, acute stage adverse events, such as acute hypersensitivity reactions requiring therapeutic 
interventions, are considered assessable by observing for 2 weeks after administration of the investigational 
product. Accordingly, after all subjects complete all scheduled tests up to 15 d for each dose group, the SMC 
will evaluate the safety-related data. With reference to the evaluation result of the SMC, the principal 
investigator and the sponsor will decide by mutual consent whether to continue the clinical study and to 
proceed with the next step. 
 
OVERALL SCHEDULE 
The screening tests shall only be performed in volunteers within 4 weeks prior to the first day (1 d) of 
investigational product administration (−28 d to −2 d) in order to select the subjects considered to be eligible 
for this clinical study. The selected subjects will be randomly assigned to either the test group or the control 
group (−1 d) and will be admitted to the Seoul National University Hospital Clinical Trials Center 2 days (-
2d) prior to administration of the investigational product.

Single-Dose Study (Intravenous Administration) 
- 10 mg, 20 mg, 50 mg, 100 mg, 200 mg, 400 mg, 800 mg, 1,200 mg IV 
 
 
The selected subjects will be admitted to the Seoul National University Hospital Clinical Trials Center 2 days 
(-2d) prior to administration of the investigational product. The skin test will be performed a day (-1 d) prior 
to administration of the investigational product. Only the subjects who did not have clinically significant 
findings in the skin test will have intravenous (IV) administration of the investigational product (hzVSF-v13 
or placebo) at 9 a.m. on the day (1d) of investigational product administration. The subjects will be required 
to perform the clinical study procedures in accordance with the predefined schedule and will be discharged 7 
days (8d) after the administration. Thereafter, the subjects will visit the Seoul National University Hospital 
Clinical Trial Center as outpatients from 9 d to 92 d in order to perform the clinical study procedures according 
to the predefined schedule. After completing all scheduled tests up to 15 d for each dose group, an independent 
SMC, established separately from this study, will evaluate the safety-related data. With reference to the 
evaluation result of the SMC, the principal investigator and the sponsor will decide by mutual consent whether 
to continue the clinical study and to proceed with the next step. 
 
10.2. RANDOMIZATION, MAINTAINING DOUBLE-BLIND AND UNBLINDING 
RANDOMIZATION 
For randomization in this clinical study, an independent person in charge of randomization will randomize 
using SAS®  ver. 9.3 (or a later version) and provide a randomization table for a code manager. The person 
in charge of randomization will deliver randomization codes, which will be prepared before the study, to the 
code manager, and the investigator will assign subject numbers in the order of subjects’ enrollment in the 
study. Each subject will be assigned the investigational product (study drug or placebo) according to the 
relevant subject number, and the clinical trial pharmacist will dispense the investigational product (study 
drug or placebo) assigned for each subject number. Randomization codes will be kept separately by the 
administrator. Using random numbers that are only open to the code manager as seed numbers, subjects 
could be assigned to the study group and the control group at a 3:1 ratio in each dose group. However, in the 
case of all dose groups except for Group 1 and Group 2 (Group 3–Group 8), the first 3 out of 8 subjects in 
each dose group shall be randomized to be 2 subjects for the study drug and 1 subject for the placebo.

DOUBLE-BLIND 
As it has been designed to investigate the safety, tolerability and pharmacokinetic characteristics after 
intravenous administration of a single dose of hzVSF-v13, it will be conducted using a double-blind method 
for each dose group.  
MAINTAINING DOUBLE-BLIND 
1. Confirmation that the investigational product cannot be distinguished 
The clinical trial pharmacist will dispense the study drug or placebo in a normal saline bag prepared to maintain 
double blinding, thereby maintaining double blinding for the principal investigator and the subjects. The label 
indicated in the protocol is a label for the study drug and placebo that are only provided to the pharmacy, and 
neither the principal investigator nor the subject will be aware of the type of drug being administered prior to 
the end of the study. The investigational products will be monitored by a separate clinical research associate 
who is not involved in this clinical study, and the relevant clinical research associate and the clinical trial 
pharmacist will be exempted from blinding. 
2. Preparation and maintenance of the randomization code and blinding envelop 
The code manager will generate randomization codes according to the randomization method, and the clinical 
trial pharmacist will dispense the investigational product (study drug or placebo) assigned for each subject 
number accordingly. The randomization codes shall be kept safe until unblinding occurs. 
The investigational product assigned to each subject will be decided based on the relevant randomization 
number, and the randomization codes shall not be disclosed unless the randomization codes are unblinded upon 
termination of the clinical study for each stage. However, to be prepared for unblinding due to occurrence of 
an emergency situation, such as a serious adverse event, the code manager will make a blinding envelop with 
randomization numbers and deliver it to the investigator for storage. In addition, the blinding envelop should 
be stored properly by the sponsor and the principal investigator until the end of the clinical study and can only 
be opened by a prescribed procedure. 
3. Storage of the investigational product 
The blinding status should be maintained before unblinding. For this, the remaining investigational products 
have to be stored and sealed properly. 
UNBLINDING  
1. Unblinding process at the end of each study or the clinical study  
After the end of each study or the the clinical study and all case report forms and data (excluding blood 
concentration measurement results) are locked, the final unblinding (randomization code for each stage) should 
be done. 
After the data are locked, the investigator makes a request for unblinding (e-mail, fax, etc.) to the code manager. 
The code manager records all information related to unblinding (unblinding date, time, and name of investigator

requesting unblinding) and send unblinded randomization codes for each stage to the investigator (e-mail, fax, 
etc.). 
2. Unblinding process at an emergency situation 
The unblinding process for unblinding due to occurrence of an emergency situation, such as a serious adverse 
event, is as follows: 
1) The subject’s safety results will be evaluated based on the United States NCI “CTCAE version 4.03.” For 
reference, in the case of being determined as a clinically significant finding, the investigator should evaluate 
the causal relationship to the investigational product while blinded. 
2) Before unblinding individually, the investigator will send the relevant information to the sponsor. 
3) It should be confirmed whether at least half of the members required to be present when unblinding have 
participated (participants when unblinding: principal investigator, investigators, and sponsor’s 
representative). 
4) All attendees will share and reconfirm the reason for unblinding. 
5) Randomization codes will be unblinded and disclosed by opening the blinding envelop, etc. 
6) After all participants confirm the disclosed randomization codes, they will sign for confirmation on a 
randomization code disclosure confirmation form. 
7) In the case that adverse events occur in the hzVSF-v13 treatment group, the investigator and the sponsor 
must discuss whether to continue the clinical study. In the case that adverse events occur in the placebo 
group, the clinical study shall continue without having a discussion. 
8) in the case that immediate disclosure of randomization codes is required to ensure the rights and interests 
as well as safety of the subject, the subject’s code may be disclosed under the responsibility of the person in 
charge of disclosure. At this time, the person in charge of disclosure shall immediately inform the sponsor 
of the randomization information of the subject and the disclosure. 
 
10.3. METHOD OF INVESTIGATIONAL PRODUCT ADMINISTRATION 
 Single-Dose Study (Intravenous Administration) 
The relevant dose of hzVSF-v13 (10–1,200 mg) will be dissolved in 100 mL of 0.9% normal saline solution 
and administered intravenously for approximately 30 minutes at 9 a.m. of 1 d.  
 
10.3.1. Other Combination Therapies 
In principle, no other drugs should be administered during the clinical study, except for the investigational 
products stated in the protocol. However, drugs may be administered depending on the decision of the 
principal investigator, if they are necessary to treat adverse events, etc. If a drug taken arbitrarily by a subject

without the decision of the principal investigator is expected to possibly have an effect on the safety and 
pharmacokinetic evaluation in this clinical study, the subject will drop out (see 9.6 Drop-out and Subject 
Substitution). The drug name (product name), administration route, daily dose, dosing period, reason for 
administration, etc. of all drugs (prescription drugs and over-the-counter drugs) administered concomitantly 
during the clinical study period have to be recorded in a CRF. 
 
10.4. SKIN TEST METHOD 
 
To be performed by an expert who is easily able to perform the procedure and interpret the result. 
 
Perform in the environment where can handle dangerous situations such as anaphylaxis. 
 
Site to be performed: Perform on the inside the forearm 
 
Wipe the area to be performed with an alcohol swab and dry it, and then drop hzVSF-v13, 
positive control solution (histamine, 1 mg/mL), and negative control solution (normal saline) on 
the skin at a distance of at least 2 to 3 cm. 
 
Lift the skin slightly with a lancet or needle to allow the test solutions to reach the epidermis. 
 
Concentration of procedure: Perform the test at a concentration diluted to approximately 1/10 of 
the scheduled dose of hzVSF-v13, and then increase to a concentration of 1/1. 
 
If the result is negative at 15 to 20 minutes after performing at a concentration of 1/10, proceed to 
a 1/1 concentration. 
 
Positive response: In the case that a wheal of at least 3 mm or swelling of at least the same size as 
the positive control solution accompanies redness

10.6. ADVERSE EVENTS 
10.6 
 
10.6.1. Recording and Reporting Adverse Events 
10.6.1.1. Adverse Event (AE) 
An adverse event is any undesirable and unintended sign (e.g., an abnormal laboratory test result), symptom, 
or disease that occurred in a subject who was administered an investigational product, and it does not 
necessarily have to have a causal relationship to the drug used in the clinical study. 
The principal investigator and investigator delegated by the principal investigator shall record all adverse 
events that occur during the clinical study. Adverse events have to be recorded using terms in the MedDRA®  
as much as possible, but if this is not possible, they should be recorded using the terms for the signs and 
symptoms observed by the principal investigator or investigator or reported by the subject. 
Symptoms and signs that appeared in the subject prior to the screening should be recorded in the 
“Medical/Surgical History” section in the subject’s CRF. All adverse events that appeared after 
administration of the investigational product should be recorded the adverse event section in the CRF, 
regardless of their relevance to the drug. The subject’s pre-existing signs and symptoms of which their 
intensity, nature, or frequency has changed or the pre-existing diseases of which their names have changed 
after administration of the investigational product shall be considered and recorded as adverse events. 
Adverse events shall be evaluated by the principal investigator and investigator delegated by the principal 
investigator. Adverse events that are recorded for the first time shall be recorded in the “Adverse Event” 
section of the CRF. Symptoms and signs of adverse events, actions taken in connection with the study drug, 
date and time of onset (if available), outcomes, course (i.e., continuous or intermittent), severity, seriousness, 
actions taken, and causal relationship to the study drug should be documented in the CRF. Details of dose 
changes and treatment information should be recorded in the appropriate pages of the CRF. 
Adverse events previously recorded in the CRF and indicated as “ongoing” in the Outcome section should 
be reviewed in subsequent visits, if necessary. In the case that adverse events are resolved, records in the 
CRF should be completed. If the frequency and severity of adverse events increase during the study period, 
new records should be started in the adverse event section. 
Besides the voluntary report from the subjects, ask the subjects in a manner not inducing to have a desired 
answer, such as “do you feel different since the last visit or administration?”, as a consistent method to 
identify adverse events. 
 
10.6.1.2. Adverse Drug Reaction (ADR) 
It refers to any harmful and unintended reaction that occurred at a certain dose of the investigational product 
where a causal relationship to the investigational product is ruled out. 
The causal relationship shall be evaluated with reference to the available information on the drug (e.g., 
investigator’s brochure or a package insert of the drug).

10.6.1.3. Unexpected Adverse Drug Reaction  
It refers to a reaction that shows a difference in the characteristics or degree of harm of the adverse drug 
reaction in view of the available information on the drug (e.g., investigator’s brochure or a package insert 
of the drug). 
 
10.6.2. Evaluation of the Severity of Adverse Events 
The severity of adverse events shall be classified based on the following criteria in consideration of the 
maximal intensity. 
 
Mild: In the case that the subject can easily tolerate with the minimal discomfort without 
disturbing the normal daily life (or function) of the subject 
 
Moderate: In the case that it causes significant discomfort disturbing the normal daily life 
(or function) of the subject 
 
Severe: In the case that it makes the normal daily life (or function) of the subject impossible 
10.6.1 
 
10.6.3. Evaluation of the Causal Relationship of Adverse Events to the Study Drug 
The causal relationship of adverse events to the investigational product shall be evaluated as 6 levels shown 
below, and the principal investigator or investigator delegated by the principal investigator shall describe 
his/her opinion. 
 
Definite relationship: In the case that an adverse event has a reasonable temporal relationship 
from the point of administration of the drug, and symptoms subside when the administration 
is discontinued and appear again when the administration is given 
 
Probable relationship: In the case that an adverse event has a reasonable temporal relationship 
from the point of administration of the drug, symptoms subside when the administration is 
discontinued, and symptoms cannot be explained reasonably based on known characteristics 
of the subject’s clinical condition 
 
Possible relationship: In the case that an adverse event has a reasonable temporal relationship 
from the point of administration of the drug, but it may have possibly occurred due to the 
subject’s clinical condition or study procedure/conditions 
 
Unlikely related: In the case that there is no reasonable relationship in terms of the temporal 
relationship between the adverse event and the drug 
 
Not related: In the case that an adverse event is clearly due to the subject’s clinical condition 
or study procedure/conditions 
 
Unassessable: In the case that a judgment cannot be made because the information is insufficient 
or contradictory, and the information cannot be supplemented or verified

10.6.4. Reporting Serious Adverse Event/Adverse Drug Reaction (AE/ADR) 
It refers to an adverse event or an adverse drug reaction that occurred at a certain dose of the investigational 
product that one of the following applies: 
 
In the case that results in death or is life-threatening 
A life-threatening case refers to an emergency situation which might cause death if medical 
treatment is not given (e.g., hepatic necrosis requiring liver transplantation, anaphylactic 
shock requiring emergency resuscitation).  
 
In the case that requires hospitalization or prolongation of hospitalization 
Receiving medical care in an emergency room, not in an inpatient room, is also considered 
hospitalization at the investigator’s discretion (e.g., acute allergic reactions). 
Hospitalization for the following are not considered as serious adverse events: 
 
Routine treatment or monitoring that is not related to a worsening of the condition, 
such as examination for hospitalization or diagnosis during pharmacokinetic 
sampling or training for administration of the study drug 
 
Hospitalization for scheduled treatment and surgery for a pre-existing condition that 
is not related to the indications of an ongoing clinical study and has not been 
deteriorated 
 
In the case that results in permanent or serious disability and dysfunction 
 
In the case that results in congenital anomaly or birth defect 
If the subject’s partner becomes pregnant during the clinical study, it should be reported 
immediately to the clinical research associate (or staff member) of ImmuneMed Inc., but it is 
not a serious adverse event, and the miscarriage, birth of deformed baby or developmental 
disorder should be reported as serious adverse events. 
 In the case that is made by other medically important decisions 
 
If a serious adverse event occurs between the administration of the investigational product and the last visit, 
the principal investigator or investigator shall report it to the PV (or staff member) of ImmuneMed Inc. 
within 24 hours regardless of the relationship of the adverse event to the study drug.

 
Blood collection will be performed at 1 d 0 h (pre-dose), 0.5, 1, 2, 4, 6, 8, 10, 12, 24 (2 d 0 h), 36 
(2 d 12 h), 48 (3 d 0 h), 60 (3 d 12 h), 72 (4 d 0 h), 96 (5 d 0 h), 120 (6 d 0 h), 144 (7 d 0 h), 168 
(8 d 0 h), 336 (15 d 0 h), 504 (22 d 0 h), 672 (29 d 0 h), 840 (36 d 0 h), 1,176 (50 d 0 h), 1,512 (64 
d 0 h), 1,848 (78 d 0 h) and 2,184 h (92 d 0 h; post-dose). At each time point, 5 mL of blood will 
be collected. 
 
Rationale for blood collection time points  
Blood will be collected for a duration of 2,184 h (approximately 13 weeks after the administration), 
which is 3 times the expected half-life (approximately 30 days) based on preclinical study results.  
 
Blood will be collected via venipuncture or a saline-locked angiocatheter inserted into the brachial 
vein. In the case of collecting blood using a saline-locked angiocatheter, approximately 1 mL of 
blood will be drawn and discarded, and approximately 5 mL of blood will be collected. Then, 1 
mL of saline will be injected into the catheter to prevent coagulation of the blood.

 
The collected blood will be immediately placed in a serum separate tube (SST) and stored at room 
temperature. After leaving it for at least 30 minutes, it will be centrifuged at 4°C for 10 minutes at 
3,000 rpm in order to separate the serum. 
 
Approximately 0.7 mL of the serum separated by centrifugation will be placed in tubes to have 3 
samples and prepared for storage in a freezer. 
 
The prepared samples will be transferred to a freezer at not more than −70°C within 1 hour and 
stored until they are analyzed. 
 
One of the three frozen samples (back-up sample) will be stored at the Seoul National University 
Hospital Clinical Trials Center, and the other two will be sent to the analyzing institution through 
a specialized shipping company.

of blood collection can be performed for the subjects who already agreed upon the written consent form for the 
research of the epidemiology of the genetic variance. Also, exploraryly evaluate the change in the proportion 
of immune cells in the lymphocytes to the baselines in peripheral blood.   
Blood collection timepoint: 5mL of blood is collected on screening day and day 92 after administrated, 
respectively.  
 
10.8.2 Blood collection method and pre-treatment and storage methods for separated serum 
5mL of blood is collected for whole blood, which is performed through saline-locked angiocatheter which is 
equipped in either venipuncture or brachial veins. When blood is collected using a saline-locked angiocatheter, 
take 1mL of blood first to be discarded then 5mL of blood is collected and 1 mL of saline is injected into 
catheter in order to prevent the blood coagulation .  
5mL of collected blood should be contained in a container (EDTA TUBE) immediately and stored in freezing 
condition (below -70℃).

The investigator should record all adverse events that occurred during the clinical study. Also, adverse 
events have to be recorded using terms in the MedDRA®  as much as possible, but if this is not possible, 
they should be recorded using the terms for the signs and symptoms observed by the investigator or 
reported by the subject. Signs and symptoms of adverse events, duration (start/end date), severity (mild, 
moderate, severe), causal relationship to the study drug, measures taken against adverse events, serious 
adverse event (yes/no), etc. shall be recorded in the CRF.

Pharmacokinetic Endpoints 
The actual blood collection time by subject will be used during the analysis of pharmacokinetic 
characteristics. If the measured concentration is lower than the lower limit of quantification (LLOQ), the 
actual blood collection has not been performed (not applicable), or the blood sample is missed (missing 
data), “<LLOQ,” “N/A” or “MD” will be entered in the blood drug concentration data. A blood 
concentration–time pattern of the study drug will be shown as a graph in a linear or log/linear shape for each 
subject, and the mean blood concentration–time curve by dose group will be shown in the same way. The 
obtained data will be used to calculate the following pharmacokinetic parameters through a 
noncompartmental method by using Phoenix®  (Pharsight, CA, USA): 
1) Single-dose study:  
Cmax, AUClast, AUCinf, Tmax, t1/2, CL (or CL/F), and Vd (or Vd/F) of hzVSG v13 
 
Cmax
