Title: A Phase 1, Randomized, Open-label, Two-arm, Parallel group, Single-dose Study to Compare the 
Pharmacokinetics and Safety of the Auto-injector and Pre-filled Syringe of CT-P17 in Healthy Subjects 
Study Phase: Phase 1 
Study Center(s): Approximately 2 study centers in approximately 1 country 
Test Investigational Drug, Dose and Route of Administration:  
CT-P17, 40 mg/0.4 mL a single subcutaneous (SC) injection via auto-injector (AI)  
Reference Investigational Drug, Dose and Route of Administration:  
CT-P17, 40 mg/0.4 mL a single SC injection via pre-filled syringe (PFS)  
Study Design and Rationale:  
This study is a phase 1, randomized, open-label, two-arm, parallel group, single-dose study, which is 
designed to compare the pharmacokinetics (PK) and safety of CT-P17 SC administration via AI and PFS in 
healthy subjects. Approximately 180 subjects will be enrolled and randomly assigned to one of the two 
treatment arms in a 1:1 ratio. In each treatment arm, all subjects will receive a single dose (40 mg) of CT-P17 
via either AI or PFS on Day 1 followed by 10 weeks during which PK, safety, and immunogenicity 
measurements will be made. The randomization to treatment assignment will be stratified by body weight 
(≥80 kg vs. <80 kg) as measured on baseline (Day -1), gender (male vs. female) and study center. 
 
A schematic of the study design is presented in Figure S1.

Number of Subjects: 
Approximately 180 subjects will be enrolled and randomly assigned (1:1) into one of two treatment arms as 
follows: 
 
Treatment Arm 1 (n=90): CT-P17 SC administration via AI 
 
Treatment Arm 2 (n=90): CT-P17 SC administration via PFS 
Study Population: Healthy male or female subjects 18 to 55 years of age, both inclusive, with a body mass 
index (BMI) between 18.0 and 29.9 kg/m2, both inclusive, are planned for enrollment. 
Inclusion Criteria: 
Subjects who meet all of the following criteria will be considered eligible to participate in the clinical study: 
1. Healthy male or female subjects, between the ages of 18 and 55 years, both inclusive (healthy is defined 
as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, 
including blood pressure and heart rate measurement, 12-lead electrocardiogram [ECG], and clinical 
laboratory tests prior to the administration of the study drug).  
2. Subject with C-reactive protein ≤1.5 times the upper limit of normal (ULN). 
3. Subject has adequate liver function as determined by following results: 
 
Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤1.5 times ULN and  


Study Procedures: 
The study will include a Screening period, Admission, Study period, and End-of-Study (EOS) visit. All study 
procedures will be performed at the time points specified in the schedule of assessments (Table 10.1). 
 
Screening Period (Day -28 to Day -2): 
Subjects will sign and date a written informed consent form and undergo procedures to determine eligibility. 
 
Admission (Day -1): 
Eligible subjects will undergo baseline assessments: recheck of inclusion and exclusion criteria, medical 
history, adverse events (AEs), prior and concomitant medications, clinical signs and symptoms of TB, 
clinical laboratory tests, vital signs, body weight, physical examination, history check for drug abuse, alcohol 
and nicotine and serum pregnancy test in women of childbearing potential. Subjects will be admitted to the 
study center and randomized to receive either CT-P17 AI or CT-P17 PFS once all pertaining tests have been 
concluded to confirm the eligibility during Screening period and Day -1 (if it is concluded that the subject is 
not eligible in Day-1 assessments, the subject will be considered as screening failure even if they passed the 
screening). 
 
Study Period (Day 1 to Day 71): 
The study drug will be administered on the subject’s lower abdomen except for the 5 cm around the subject’s 
navel.  
Subjects will be confined to the study center until completion of the 48-hour assessments after the 
administration of the study drug (Day 1) and admission can be extended depending on the subject’s and study 
center’s availability. The consecutive study visits will be carried out on an out-patient basis.  
 
Clinical laboratory testing and vital sign measurements will be obtained during the study period. For 
hypersensitivity monitoring, vital signs will be measured and either 3-lead or 12-lead ECG can be used. 
Local site pain using 100 mm visual analogue scale (VAS) and injection site reactions will be assessed 
after study drug administration. A physical examination will be performed. Immunogenicity samples will 
be obtained and AEs, concomitant medications, and clinical signs and symptoms of TB will be monitored 
throughout the study. Blood samples for PK analysis will be collected from all subjects at the predefined 
time points in the following table: 
PK sampling time points 
Day 1 Pre-dose (within 60 minutes prior to administration of the study drug) 
Day 1 (6 hours after the administration of the study drug); ±15 minutes 
Day 1 (12 hours after the administration of the study drug); ±1 hour 
Day 2 (24 hours after the administration of the study drug); ±2 hours 
Days 3, 4, 5, 5.5, 6, 6.5, 7, 8, and 9 (48, 72, 96, 108, 120, 132, 144, 168, and 192 hours, respectively, 
after the administration of the study drug); ±2 hours 
Days 15 and 22 (336 and 504 hours, respectively, after the administration of the study drug); ±4 hours  
Days 29, 43, 57, and 71 (i.e., EOS) after the administration of the study drug; ±1 day 
 
End-of-Study Visit (Day 71): 
The EOS visit will be performed on Day 71, for all subjects including those who discontinued prematurely. 
Subjects will return to the study center and undergo the following PK and safety assessments: PK and 
immunogenicity sampling; collection of information related to AEs and concomitant medications; serum 
pregnancy tests in women of childbearing potential; TB monitoring and IGRA; vital signs; body weight; 12-
lead ECG; clinical laboratory tests; and physical examination. The acceptable tolerance window for PK, 
safety, and immunogenicity assessments is ±1 day for EOS (Day 71) assessments.

syphilis will be tested for the subject’s eligibility determination. 
Sample Size: 
A sample size of 162 (81 subjects from each arm) will provide at least 90% power to show similarity in PK 
of CT-P17 AI and CT-P17 PFS using 90% confidence interval (CI) approach based on 80% to 125% 
equivalence margin, expected geometric mean ratio of 1.0, and coefficient of variation (CV) of 45%, which is 
assumed based upon historical PK data in healthy subjects. Considering a 10% drop-out rate, approximately 
180 subjects (90 subjects in each treatment arm) will be randomized.

Statistical Analyses: 
Pharmacokinetic analysis: All PK analyses will be conducted on the PK population. The PK parameters of 
CT-P17 will be analyzed using non-compartmental methods based on the actual sampling times. The primary 
PK analysis will assess the bioequivalence of CT-P17 SC administration via AI versus PFS in terms of 
AUC0-inf, AUC0-last, and Cmax. The primary PK parameters will be based on an analysis of covariance 
(ANCOVA) model with covariate(s). Point estimates (geometric means and ratio of geometric means) will be 
calculated from back transforming the least squares means of the natural log-transformed values of AUC0-inf, 
AUC0-last, and Cmax and difference in the least squares means. The PK of CT-P17 administered via AI and 
PFS will be determined to be equivalent if the 90% CIs for the ratios of geometric means of primary 
endpoints is within the acceptance interval of 80% to 125%. 
Pharmacokinetic parameters will be presented in data listings and summarized in tables. The tables will 
display the following descriptive statistics: number of subjects, mean, standard deviation, median, minimum, 
maximum, geometric mean, and CV. 
For secondary endpoints, following PK parameters will be assessed: %AUCextrap, Tmax, Vz/F, λz, t1/2, and 
CL/F. 
Additional PK analyses may be performed as detailed in the statistical analysis plan. 
Safety and immunogenicity analysis: All safety and immunogenicity analyses will be conducted on the safety 
population, and listed and summarized by treatment arm. The number and percentage of subject experienced 
AEs will be summarized by treatment arm using system organ class and preferred term. Adverse events will 
be summarized by severity and relationship to study drug. Serious adverse events will be listed separately. 
Adverse events will be recorded according to the Common Terminology Criteria for Adverse Events v5.0 and 
will be coded to system organ class and preferred term according to the Medical Dictionary for Regulatory 
Activities. Prior and concomitant medications will be coded using the WHO Drug Dictionary. These 
medications will be tabulated by drug class and preferred term.

1 Introduction 
1.1 Background 
Tumor necrosis factor (TNF)-α, a proinflammatory cytokine, is a key mediator of 
inflammation shown to be a central factor in inflammatory immune response 
(Harriman et al 1999; Hsia et al 2006). In general, TNF-α is produced mainly by 
macrophages, but also by a broad variety of other cell types. It has a wide spectrum of 
activities including coordinating host immune and inflammatory response to infectious, 
malignant, and autoimmune conditions. There are 2 types of TNF receptors, p55 and p75, 
part of a large family of structurally related cell-surface receptors (Bazzoni and Beutler 
1996). There is evidence that the p75 receptor stimulates T cells proliferation and suppresses 
TNF-α-mediated inflammatory responses, whereas the p55 receptor appears to be critical in 
triggering host defense and inflammatory responses (Tartaglia et al 1993; Peschon et al 
1998). 
Large amounts of TNF-α are released in response to lipopolysaccharide, other bacterial 
products, and interleukin-1. Tumor necrosis factor-alpha induces proinflammatory cytokines 
such as interleukin-1 and interleukin-6, enhances leukocyte migration, activates neutrophil 
and eosinophil functional activity, and induces acute phase reactants, other liver proteins, and 
tissue-degrading enzymes. Although there is a benefit to TNF-α expression in response to 
infection or injury, there are increased concentrations associated with a variety of 
inflammatory conditions such as rheumatoid arthritis (RA), Crohn’s disease, ulcerative 
colitis, uveitis, ankylosing spondylitis, psoriatic arthritis, and plaque psoriasis. 
Greater understanding of the role of inflammatory mediators has produced effective biologic 
treatments for inflammatory conditions, including Humira (adalimumab), a fully humanized 
anti-TNF-α monoclonal antibody. Adalimumab is structurally and functionally analogous to 
naturally occurring human immunoglobulin G1 (IgG1) and demonstrates a high specificity 
and affinity for TNF. Adalimumab binds to TNF-α and blocks its interaction with the cell 
surface TNF receptors, p55 and p75 (Humira USPI 2019). It does not bind other cytokines 
such as lymphotoxin. Adalimumab also lyses surface TNF expressing cells in vitro in the 
presence of complement (Humira USPI 2019). 
1.2 CT-P17 Product Description 
CT-P17, containing the active ingredient adalimumab, is a recombinant humanized 
monoclonal antibody that is being developed as a similar biological medicinal product to the 
original product, Humira. The original product was originally approved in the United States 
(US) in December of 2002 and in the European Union (EU) in September of 2003 (FDA 

CELLTRION, Inc. 
CT-P17 
Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 17 
2002, EMA EPAR for Humira 2017, Humira SmPC 2018). In the EU, Humira is indicated for 
the following conditions: RA, juvenile idiopathic arthritis, axial spondyloarthritis (ankylosing 
spondylitis [AS], axial spondyloarthritis without radiographic evidence of AS), psoriatic 
arthritis, psoriasis, pediatric plaque psoriasis, hidradenitis suppurativa, Crohn’s disease, 
pediatric Crohn’s disease, ulcerative colitis, uveitis and pediatric uveitis; in the US, Humira is 
indicated for the same conditions except axial spondyloarthritis without radiographic 
evidence of AS, and pediatric plaque psoriasis (Humira USPI 2019, Humira SmPC 2018). 
The original product, Humira, is supplied as a sterile, preservative-free solution of 
adalimumab for subcutaneous (SC) administration (Humira USPI 2019). Humira is supplied 
in two strengths: 50 mg/mL (40 mg/0.8 mL) and 100 mg/mL (40 mg/0.4 mL). 
CT-P17 is manufactured using a Chinese Hamster Ovary cell line by fed-batch cell culture, 
followed by harvest, purification, formulation, and subsequent fill-finish operations. The 
primary amino acid sequences of adalimumab in CT-P17 are identical to those of Humira. 
CT-P17 will be supplied in a pre-filled syringe (PFS) and auto-injector (AI) at a concentration 
of 100 mg/mL (40 mg/0.4 mL) as a clear to opalescent, colorless to brown liquid for 
subcutaneous administration. The CT-P17 drug product will have the same pharmaceutical 
form and strength as Humira and is intended to have a highly similar quality profile to 
Humira. 
CELLTRION, Inc. plans to seek approval for all indications for which the original product 
has been approved by demonstrating similarity of CT-P17 with the original product through 
an extensive array of quality, nonclinical and clinical comparability assessments. 
1.3 Nonclinical Studies 
Detailed information regarding the nonclinical pharmacology and toxicology of CT-P17 can 
be found in the investigator’s brochure (IB). 
1.4 Clinical Studies 
The safety, tolerability, and pharmacokinetics (PK) of adalimumab in healthy subjects were 
evaluated in a series of phase 1 studies. 
Study DE024 was a single center, double-blind, randomized, placebo-controlled, parallel-
group, ascending single-dose study in healthy male subjects. A total of 80 subjects (60 active 
and 20 placebo) participated in the study. Active subjects received a single intravenous (IV) 
dose of 1 mg/kg adalimumab over 2 to 3 minutes or 0.1, 0.3, and 1 mg/kg adalimumab via SC 
injection. Results demonstrated that following SC administration of adalimumab the mean 
maximum observed serum concentration (Cmax) and area under the concentration-time curve 

CELLTRION, Inc. 
CT-P17 
Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 18 
(AUC) from zero to infinity (AUC0-inf) increased with increasing dose, with dose proportional 
increases noted at the 0.3 and 1 mg/kg SC doses only. The time to Cmax (Tmax) ranged from 48 
to 336 hours and the mean half-lives ranged from 284 to 433 hours across doses. 
Study DE015 was an open-label, randomized, parallel-group, single-dose study to assess the 
absolute and relative bioavailability of three injectable formulations of human anti-TNF 
antibody D2E7 in healthy male and female subjects. Subjects received 40 mg D2E7 as three 
different formulations via IV (50 mg/mL D2E7, with Tween-80) or SC injection (25 mg/mL 
D2E7, without Tween-80; 50 mg/mL D2E7, with Tween-80; and 50 mg/mL D2E7, without 
Tween-80). The results indicated that the mean Cmax and Tmax for the three SC formulations of 
D2E7 were comparable. The overview and results of Studies DE024 and DE015 can be found 
in Clinical Pharmacology and Biopharmaceutics Review(s), FDA. 
An overview of the safety profile of Humira, including undesirable effects, can be found in 
the Humira Summary of Product Characteristics (SmPC), European Public Assessment 
Report (EPAR) for Humira, and prescribing information for US-licensed Humira (Humira 
SmPC 2018; EMA EPAR for Humira 2017; Humira USPI 2019).  
One study of CT-P17 has been completed. CT-P17 1.2 is a pilot study, which is a randomized, 
double-blind, single-dose study to evaluate the safety and PK of CT-P17 and EU-approved 
Humira in healthy male subjects. Results up to Day 120 showed that CT-P17 and EU- 
approved Humira were safe and well-tolerated in the healthy male subjects, and the PK 
results (Cmax, AUC0-inf and AUC0-last) were comparable between the groups. In addition, there 
are three clinical trials with CT-P17 that are ongoing or planned. CT-P17 1.1 is an ongoing 
randomized, double-blind, single-dose study to compare the PK and safety of CT-P17, US-
licensed Humira and EU-approved Humira in healthy subjects. Two Phase 3 studies are also 
ongoing and planned; CT-P17 3.1 is a randomized, active-controlled, double-blind study to 
compare efficacy and safety of CT-P17 with EU-approved Humira when co-administered 
with methotrexate in patients with moderate to severe active RA that is ongoing, while CT-
P17 3.2 is a planned open-label, non-randomized, multiple-dose study to evaluate usability of 
CT-P17 AI in patients with moderate to severe active RA. 
1.5 Rationale for Study 
The introduction of biosimilar (follow-on) medicinal products is desirable as they will 
enhance patient access by expanding the field of competing biotechnological treatments. The 
purpose of this study is to compare the PK, safety, and immunogenicity of the CT-P17 AI and 
CT-P17 PFS after a single SC injection of 40 mg of each product to healthy subjects 
following the recommendations of the guidance for industry, “Rheumatoid Arthritis: 
Developing Drug Products for Treatment” (DHHS 2013).

Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 19 
The dose of CT-P17 (40 mg) selected for this study is in line with the approved labeling for 
Humira (Humira SmPC 2018; Humira USPI 2019).  
CT-P17 has been developed for SC injection, considering the benefits in terms of patient 
convenience, better compliance, reduced pharmacy preparation times, and optimization of 
medical resources.  
This study is designed to compare the PK of CT-P17 SC administration via AI versus PFS in 
healthy subjects. Auto-injectors offer several advantages over PFS including simplified self-
administration, reduced patient anxiety, improved safety by reducing the risk of injury and 
improper administration, as well as improved compliance through controlled and 
standardized administration.  
The study will be conducted in healthy subjects to avoid potentially high variability of the 
exposure of adalimumab if administered to patients with underlying and/or concomitant 
disease and concomitant medications. Bioequivalence will be based on the criteria of area 
under the concentration-time curve (AUC) from time zero to infinity (AUC0-inf), AUC from 
time zero to the last quantifiable concentration (AUC0-last), and Cmax. 
1.6 Risk–Benefit Assessment 
Information about the risk following the administration of adalimumab was taken from the 
prescribing information for US-licensed Humira (Humira USPI 2019) and Humira SmPC for 
EU-approved Humira (Humira SmPC 2018). In view of the structural, biological, and 
toxicological similarity to Humira, CT-P17 is expected to display a similar safety profile. 
The proposed safety screening and monitoring assessments are deemed to be sufficient to 
monitor potential risks of CT-P17 administration. Since adalimumab will be administered 
only once at the approved dosage of 40 mg, the overall risk of the study for healthy subjects 
is considered to be acceptable. No therapeutic benefit from adalimumab treatment is intended 
for the healthy subjects in this study.

3 Investigational Plan 
3.1 Study Design 
This study is a phase 1, randomized, open-label, two-arm, parallel group, single-dose study, 
which is designed to compare the PK and safety of the CT-P17 SC administration via AI and 
PFS in healthy subjects. Approximately 180 subjects will be enrolled and randomly assigned 
to one of the two treatment arms in a 1:1 ratio. In each treatment arm, all subjects will receive 
a single dose (40 mg) of CT-P17 via either AI or PFS on Day 1 followed by 10 weeks during 
which PK, safety, and immunogenicity measurements will be made. The randomization to 
treatment assignment will be stratified by body weight (≥80 kg vs. <80 kg) as measured on 
baseline (Day -1), gender (male vs. female) and study center. 
A schematic of the study design is presented in Figure 3−1. Refer to Section 3.2 for the study 
overview, including procedures to be performed during the study.

Study Design Overview 
 
3.2 Study Overview 
The study will include a Screening period, Admission, Study period, and End-of-Study (EOS) 
visit. All study procedures will be performed at the time points specified in the schedule of 
assessments (Table 10-1). 

CELLTRION, Inc.

Protocol Version 2.0 
 
Page 22 
3.2.1 Screening Period (Day -28 to Day -2) 
Subjects will sign and date a written informed consent form and undergo procedures to 
determine eligibility. If necessary, a prescreening process may be carried out according to the 
standard operating procedures (SOP) of the study center.   
During the screening period, retest for screening is permitted only once by the investigator’s 
judgement. If the repeated test result is again not suitable or indeterminate for inclusion, the 
subject will be screen failed.  
3.2.2 Admission (Day -1) 
Eligible subjects will undergo baseline assessments: recheck of inclusion and exclusion 
criteria, medical history, adverse events (AEs), prior and concomitant medications, clinical 
signs and symptoms of TB, clinical laboratory tests, vital signs, body weight, physical 
examination, history check for drug abuse, alcohol and nicotine and serum pregnancy test in 
women of childbearing potential.  
Subjects will be admitted to the study center and randomized to receive either CT-P17 AI or 
CT-P17 PFS once all pertaining tests have been concluded to confirm the eligibility during 
Screening period and Day -1 (if it is concluded that the subject is not eligible in Day-1 
assessments, the subject will be considered as screening failure even if they passed the 
screening). 
3.2.3 Study Period (Day 1 to Day 71) 
The study drug will be administered on the subject’s lower abdomen except for the 5 cm 
around the subject’s navel. 
Subjects will be confined to the study center until completion of the 48-hour assessments 
after the administration of the study drug (Day 1) and admission can be extended depending 
on the subject’s and study center’s availability. The consecutive study visits will be carried 
out on an out-patient basis.  
Clinical laboratory testing and vital sign measurements will be obtained during the study 
period. For hypersensitivity monitoring, vital sign measurements will be performed before 
the start of the study drug administration (within 15 minutes) and at 3, 6, 12, and 24 hours 
after the administration of the study drug on Day 1. The tolerance window for 
hypersensitivity monitoring is ±30 minutes for 3 and 6 hours, and ±60 minutes for 12 and 24 
hours after the administration. Either 3-lead or 12-lead electrocardiogram (ECG) can be 
used for hypersensitivity monitoring at 3 hours (±30 minutes) after the administration of the

Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 23 
study drug on Day 1, and additional ECGs can be performed throughout the study if the 
subject experiences cardiac symptoms. Local site pain using 100 mm visual analogue scale 
(VAS) will be assessed immediately (within 15 minutes) after study drug administration (Day 
1) and injection site reactions will be assessed 30 minutes (±10 minutes) after study drug 
administration. A physical examination will be performed on Day 3. Immunogenicity 
samples will be obtained in prior to the administration of the study drug on Day 1 (within 60 
minutes prior to administration of the study drug), and on Day 15 (± 4 hours), 29 (± 1 day), 
57 (± 1 day) and 71 (EOS, ± 1 day). Adverse events, concomitant medications, and clinical 
signs and symptoms of TB will be monitored throughout the study. Blood samples for PK 
analysis will be collected from all subjects at the predefined time points in the following 
table: 
PK sampling time points 
Day 1 Pre-dose (within 60 minutes prior to administration of the study drug) 
Day 1 (6 hours after the administration of the study drug); ±15 minutes 
Day 1 (12 hours after the administration of the study drug); ±1 hour 
Day 2 (24 hours after the administration of the study drug); ±2 hours 
Day 3, 4, 5, 5.5, 6, 6.5, 7, 8, and 9 (48, 72, 96, 108, 120, 132, 144, 168, and 192 hours, respectively, after 
the administration of the study drug); ±2 hours 
Day 15 and 22 (336 and 504 hours, respectively, after the administration of the study drug); ±4 hours  
Day 29, 43, 57, and 71 (i.e., EOS) after the administration of the study drug; ±1 day 
3.2.4 End-of-Study Visit (Day 71) 
The EOS visit will be performed on Day 71, for all subjects including those who discontinued 
prematurely. Subjects will return to the study center and undergo the following PK and safety 
assessments: PK and immunogenicity sampling; collection of information related to AEs and 
concomitant medications; serum pregnancy tests in women of childbearing potential; TB 
monitoring and interferon-γ release assay [IGRA] assessment; vital signs; body weight;12-
lead ECG; clinical laboratory tests; and physical examination. The acceptable tolerance 
window for PK, safety, and immunogenicity assessments is ±1 day for EOS (Day 71)

14. Subject has smoked 10 or more cigarettes per day in the recent 12 weeks prior to the 
administration of the study drug (Day 1) and/or is unable to refrain from smoking up to 
24 hours after the administration of the study drug. 
15. In the opinion of the investigator, the subject is not eligible for the study participation 
for any reason (including clinical laboratory results) or shows evidence of a condition 
(e.g., psychological or emotional problem, any disorder or resultant therapy) that is 
likely to invalidate an informed consent or limit the ability of the subject to comply 
with the protocol requirements. Subject is unable to understand the protocol 
requirements, instructions, study-related restrictions, or the nature, scope, and possible 
consequences of the clinical study or is unable to give written informed consent or to 
comply fully with the protocol. 
16. Subject is vulnerable (e.g., employees of the study center or any other individuals 
involved with the conduct of the study, or immediate family members of such 
individuals, persons kept in prison, or other institutionalized persons by law 
enforcement). 
4.3 Subject Withdrawal/Discontinuation and Replacement 
Subjects will be discontinued from the study prematurely for the following reasons: 
 Withdrawal of consent: Subjects have the right to withdraw from the study at any time for 
any reason.  
 Protocol deviation: The subject may be withdrawn by the investigator after discussion 
with the sponsor: 
– If protocol deviations that may affect study objectives occur, or 
– If it is discovered that the subject has entered the study in violation of the protocol. 
 Adverse event: If subject reports symptoms that are considered unacceptable by the 
investigator and/or sponsor, he or she will be withdrawn from the study. 
 Subject dies. 

CELLTRION, Inc. 
CT-P17 
Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 28 
When a subject withdraws from the study, the reason(s) for withdrawal shall be recorded by 
the investigator in both the source documents and electronic case report form (eCRF).  
If a subject discontinues prematurely after dosing, the subject will be asked to return to the 
study center and will undergo all EOS (i.e., Day 71) assessments.  All subjects who withdraw 
from the study because of an AE or clinical laboratory abnormality will be followed-up at 
suitable intervals in order to evaluate the course of the AE or laboratory abnormality and to 
ensure resolution or stabilization of the event. The subsequent outcomes of these events will 
be recorded in the both the source documents and eCRF. 
For subjects who are lost to follow-up (i.e., those subjects whose status is unclear because 
they fail to appear for study visits without stating an intention to withdraw), the investigator 
will show due diligence by documenting in the source documents steps taken to contact the 
subject, e.g., dates of telephone calls, registered letters, etc. Subjects who fail to return for 
final assessments will be contacted by the center in an attempt to have him or her comply 
with the protocol. The status of subjects who fail to complete final assessments will be 
documented in the both the source documents and eCRF. 
For screen failed subjects, rescreen will be allowed only once after receiving informed 
consent form (ICF) again with new screening ID; however, subjects withdrawn (after 
randomization) will not be replaced. 
4.4 Premature Termination of the Clinical Trial 
The sponsor reserves the right to terminate the study at any time for reasonable medical 
and/or administrative reasons. As far as possible, this should occur after mutual consultation. 
If the study is terminated prematurely by the sponsor, all subjects will be kept fully informed 
and an appropriate follow-up examination of the subjects will be arranged. The investigator 
will inform the institutional review board (IRB) or independent ethics committee (IEC) of 
any premature termination or suspension of the study, where applicable.

5 Study Treatments 
5.1 Method of Assigning Subjects to Treatment Arms 
Enrolled subjects who meet all of the inclusion and none of the exclusion criteria will be 
randomly assigned in a 1:1 ratio into one of two treatment arms. Randomization numbers will 
be assigned on Day -1 before administration of the study drug. The randomization will be 
balanced by using permuted blocks or, other appropriate randomization methods can be used. 
As it is known that the body weight and gender are potential impact factors on 
pharmacokinetic profile, and considering that it will be a multi-center study, the 
randomization to treatment assignment will be stratified by body weight (≥80 kg vs. <80 kg) 
as measured on Day -1, gender (male vs. female) and study center. 
5.2 Treatment Administered 
On Day 1, subjects who are randomly assigned to one of two treatment arms will receive a 
single dose (40 mg) of CT-P17 via either AI or PFS. The treatments arms are as follows: 
 Treatment Arm 1 (n=90): CT-P17, 40 mg/0.4mL administered as a single SC injection via 
AI 
 Treatment Arm 2 (n=90): CT-P17, 40 mg/0.4mL administered as a single SC injection via 
PFS 
All subjects will fast overnight (nothing to eat or drink except water) for at least 8 hours prior 
to study drug administration. Subjects will remain fasted for 4 hours after study drug 
administration. Water is permitted as desired except for the period 1 hour before and 1 hour 
after study drug administration.  
The study drug will be administered on the subject’s lower abdomen except for the 5 cm 
around the subject’s navel. Immediately after the study drug administration, a cotton ball or 
gauze pad will be pressed over the injection site and held it for 10 seconds without rubbing. 
The time of dose administration will be called “0” hour. 
5.3 Identity of Investigational Products

5.8 Subject Restrictions During the Study 
5.8.1 Food, Fluid, and Activity 
 Alcohol consumption will be avoided from 24 hours before any study visit and while 
subjects are confined to the study center. Subjects will abstain from alcohol-containing 
products for 24 hours prior to each PK sample time point. Subjects may undergo an 
alcohol breath test at the discretion of the investigator. Subjects will not exceed an alcohol 
consumption of 7 units per week during the study from time of signing the ICF through 
the EOS visit. One unit is equivalent to a half-pint (285 mL) of beer/lager, one measure 
(25 mL) of spirits, or one small glass (125 mL) of wine. 
 Subjects will not be permitted to drink caffeine-containing products (e.g., coffee, black 
tea, cola) or use caffeine or xanthine-containing products for 48 hours prior to the 
administration of the study drug and 24 hours prior to each PK sample time point. 
Subjects will not be permitted to use nicotine-containing products up to 24 hours after the 
study drug administration. At all times during the study, subjects will not consume more 
than 10 cigarettes per day (24 hours), or equivalent. 
 Strenuous activity (e.g., heavy lifting, weight training, calisthenics, and aerobics) is 
prohibited from 72 hours prior to Day -1 and 72 hours prior to each PK sample time 
point. Mild physical activity may be resumed after Day 7. 
 All subjects will fast (nothing to eat or drink except water) for at least 8 hours prior to 
study drug administration (Day 1). Subjects will remain fasted for 4 hours after study 
drug administration. Water is permitted as desired except for the period 1 hour before and 
1 hour after study drug administration. No outside food or drink is permitted at the study 
center. All meals and snacks while the subjects are confined will be provided by the study 
center. 
5.8.2 Contraception 
 
Subject and their partner of childbearing potential must agree to use a highly effective 
method of contraception throughout the study and for 5 months after the administration 
of assigned treatment. Examples include the following:  
- 
Combined (estrogen and progestogen containing) or progestogen-only hormonal 
contraception associated with inhibition of ovulation 
- 
Intrauterine devices 

CELLTRION, Inc.

Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 34 
- 
True abstinence, when this is in line with the preferred and usual lifestyle of the 
subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-
ovulation methods), declaration of abstinence for the duration of exposure to 
investigational drug, and withdrawal are not acceptable methods of contraception. 
- 
Condom in addition to use of spermicide, hormonal contraceptive or barrier 
method in female; for male subject with his female partner of childbearing 
potential only. Spermicide condom (condoms coated with spermicide) use alone 
is not allowed.   
 A man or woman is of childbearing potential if, in the opinion of the investigator, he or 
she is biologically capable of having children and is sexually active. Male and female 
subjects and their partners who have been surgically sterilized for less than 24 weeks 
prior to the date of informed consent must agree to use any medically acceptable methods 
of contraception. Menopausal females must have experienced their last period more than 
1 year prior to the date of informed consent to be classified as not of childbearing 
potential. 
 Male subjects are not permitted to donate sperm or father a child within 5 months after 
administration of study drug.

6 Study Assessments and Procedures 
Before performing any study procedures, all potential subjects will sign and date an ICF. The 
investigator will address all questions raised by the subject before the subject signs the ICF. 
The investigator will also sign and date the ICF. Subjects will undergo study procedures at 
the time points specified in the schedule of assessments (Table 10-1). 
6.1 Pharmacokinetic Assessments 
Blood samples for PK assessments of CT-P17 will be collected from all subjects at the time 
points specified in the schedule of assessments (Table 10-1). Analysis of the samples will be 
performed at the bioanalytical laboratory.  
The following serum PK parameters will be calculated for CT-P17 using actual sampling 
times rather than scheduled sampling times.  
Primary endpoints: 
 Area under the concentration-time curve from time zero to infinity (AUC0-inf) 
 Area under the concentration-time curve from time zero to the last quantifiable 
concentration (AUC0-last) 
 Maximum serum concentration (Cmax) 
Secondary endpoints: 
 Percentage of the area extrapolated for calculation of AUC0-inf (%AUCextrap) 
 Time to Cmax (Tmax) 
 Apparent volume of distribution during the terminal phase after non-intravenous 
administration (Vz/F) 
 Terminal elimination rate constant (λz) 
 Terminal elimination half-life (t1/2) 
 Apparent total body clearance (CL/F)

Page 36 
6.2 Safety Assessments 
Safety assessments will be performed on AEs (including serious AEs [SAEs]), AEs of special 
interest (AESI) (injection site reactions, hypersensitivity/allergic reactions, infections, and 
malignancies), immunogenicity, hypersensitivity/allergic reaction assessments by additional 
ECG and vital sign monitoring (including systolic and diastolic blood pressure, heart rate, 
respiratory rate, and body temperature), vital sign and weight measurement, ECG, physical 
examination, IGRA, chest X-ray, pregnancy testing, clinical laboratory testing (including 
hematology, serum chemistry, and urinalysis), local site pain using 100 mm VAS, signs and 
symptoms of TB, and prior and concomitant medications monitored throughout the study. 
Hepatitis B, hepatitis C, HIV (HIV-1 and HIV-2) status and syphilis will be tested for the 
subject’s eligibility determination. 
6.2.1 Adverse Events 
6.2.1.1 Definitions of Adverse Events 
The investigator is responsible for reporting all AEs that are observed or reported during the 
study, regardless of their relationship to study drug or their clinical significance.  
An AE is defined as any untoward medical occurrence associated with the use of a drug in 
humans, whether or not considered drug related. Subjects will be instructed to contact the 
investigator at any time after the ICF was signed if any symptoms develop. 
A treatment-emergent AE (TEAE) is defined as any event not present before exposure to 
study drug or any event already present that worsens in severity or frequency after exposure 
to study drug. This includes any occurrence that is new in onset or aggravated in severity or 
frequency from the baseline condition; abnormal results of diagnostic procedures including 
laboratory test abnormalities are considered AEs if they fulfill the following: 
 Result in discontinuation from the study 
 Require treatment or any other therapeutic intervention 
 Require further diagnostic evaluation (excluding a repetition of the same procedure to 
confirm the abnormality) 
 Are associated with clinical signs or symptoms judged by the investigator to have a 
significant clinical impact 
Medical interventions such as surgery, diagnostic procedures, and therapeutic procedures are 
not AEs but the action taken to treat the medical condition. They should be recorded as 

CELLTRION, Inc. 
CT-P17 
Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 37 
treatment(s) of the AEs. The event term of primary cause should be recorded and reported 
instead of the term of surgery, diagnostic procedure, or therapeutic procedure. 
6.2.1.1.1 
Adverse Events of Special Interest 
The following AESIs will be reported using the same process as for AEs: 
Injection site reactions 
Injection site reactions will be observed after study drug administration and assessed based 
on Common Terminology Criteria for Adverse Events (CTCAE) v5.0. All AEs related to 
injection site reaction including erythema, itching, hemorrhage, pain, and swelling will be 
reported. 
Hypersensitivity/allergic reactions 
All AEs related to hypersensitivity and allergic reactions occurring within 24 hours after the 
study drug administration will be reported. 
Infection 
All AEs related to infection including TB, sepsis, and other opportunistic infections will be 
reported. 
Malignancy 
All AEs related to malignancy including but not limited to the following: hepatosplenic T-cell 
lymphoma, leukemia, lymphoma, melanoma, and Merkel cell carcinoma. 
6.2.1.1.2 
Serious Adverse Events 
An SAE is defined as any untoward medical occurrence that at any dose: 
 Results in death 
 Is immediately life-threatening 
 Requires in-patient hospitalization or prolongation of existing hospitalization 
 Results in persistent or significant disability/incapacity 
 Is a congenital anomaly/birth defect 

CELLTRION, Inc. 
CT-P17 
Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 38 
Important medical events that may not result in death, be life threatening, or require 
hospitalization may be considered SAEs when, based upon appropriate medical judgment, 
they may jeopardize the subject or may require medical or surgical intervention to prevent 
one of the outcomes listed in this definition. Examples of such medical events include allergic 
bronchospasm requiring intensive treatment in an emergency room or at home, blood 
dyscrasias or convulsions that do not result in in-patient hospitalization, or the development 
of drug dependency or drug abuse. 
6.2.1.1.3 
Suspected Unexpected Serious Adverse Reactions 
A suspected unexpected SAE is defined as an event of which the nature or severity is not 
consistent with the applicable product information (e.g., IB) for an unapproved 
investigational product. Assessment of expectedness will be made with the use of the IB. 
Therefore, if a treatment-related SAE occurs and it was not mentioned in the applicable 
product information, then it will be reported as a SUSAR (Suspected Unexpected Serious 
Adverse Reaction). 
6.2.1.2 Eliciting and Documenting Adverse Events 
Adverse events will be assessed from the time the ICF is signed and until the end of the 
subject’s participation in the study. All AEs will be followed until resolution or improvement 
to baseline, death, confirmed by the investigator that no further improvement could be 
expected, no more collection of clinical or safety data, or final database closure. Adverse 
events of special interest (e.g., injection site reactions, hypersensitivity/allergic reactions, 
infections, and malignancies) will be closely monitored. 
At each visit, subjects will be asked a standard question to elicit any medically related 
changes in their well-being. They will also be asked if they have been hospitalized, had any 
accidents, used any new medications, or changed concomitant medication regimens (both 
prescription and OTC medications). 
In addition to subject observations, AEs will be documented from any data collected on the 
AE page of the eCRF (e.g., laboratory values, physical examination findings, ECG changes) 
or other documents that are relevant to subject safety. 
6.2.1.3 Reporting Adverse Events 
All AEs reported or observed during the study will be recorded in both the source documents 
and on the AE page of the eCRF. Information to be collected includes drug treatment, type of 
event, time of onset, action taken with study drug, investigator-specified assessment of 

CELLTRION, Inc. 
CT-P17 
Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 39 
severity and relationship to study drug, time of resolution of the event, seriousness, as well as 
any required treatment or evaluations, and outcome. 
Adverse events resulting from concurrent illnesses, reactions to concurrent illnesses, 
reactions to concurrent medications, or progression of disease states will also be reported. 
Adverse events will be recorded according CTCAE v5.0. The Medical Dictionary for 
Regulatory Activities (MedDRA) will be used to code all AEs.  
Any medical condition that is present at the time that the subject is screened but does not 
deteriorate will not be reported as an AE. However, if it deteriorates at any time during the 
study, it will be recorded as an AE. 
The investigator’s assessment of an AE’s relationship to study drug is part of the 
documentation process, but it is not a factor in determining what is or is not reported in the 
study. If there is any doubt as to whether a clinical observation is an AE, the event will be 
reported. 
The severity and the relationship or association of the study drug in causing or contributing to 
the AE will be characterized as defined in Sections 6.2.1.5 and 6.2.1.6, respectively. 
Adverse events (and SAEs) should be reported until the EOS visit regardless of the 
relationship to the study drug. After the EOS visit, serious adverse drug reactions will be 
reported to CELLTRION, Inc. or its designee. 
6.2.1.4 Reporting Serious Adverse Events 
Any AE considered serious by the investigator or which meets SAE criteria (Section 
6.2.1.1.2) must be reported to 
 PVG and the sponsor immediately (within 24 hours after 
the study center staff first notices about the event).  
The following contact information is to be used for SAE reporting: 
 
 
 
 
 
 
If the subject is hospitalized during an SAE or because of an SAE, a copy of the hospital 
discharge summary will be faxed (or e-mailed) to 
 PVG as soon as it becomes available. 
Withdrawal from the study and all therapeutic measures will be at the discretion of the 
principal investigator or sub-investigator.  

CELLTRION, Inc. 
CT-P17 
Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 40 
CELLTRION, Inc. or its designee is responsible for reporting relevant SAEs to the competent 
authority, other applicable regulatory authorities, and participating investigators, in 
accordance with European Clinical Trials Directive (Directive 2001/20/EC), International 
Council for Harmonisation (ICH) guidelines, and/or local regulatory requirements. 
CELLTRION, Inc. or its designee is responsible for reporting fatal or life-threatening 
SUSARs (expedited reports) to the regulatory agencies and competent authorities by 
telephone or fax within 7 calendar days after being notified of the event. CELLTRION, Inc. 
or its designee should report other relevant SAEs associated with the use of the study drug to 
the appropriate competent authorities (according to local guidelines), investigators, and 
central ethics committees by a written safety report within 15 calendar days of notification. 
Adverse events associated with hospitalization or prolongations of hospitalization are 
considered as SAEs. Any initial admission (even if less than 24 hours) to a healthcare facility 
meets these criteria. Admission also includes transfer within the hospital to an acute/intensive 
care unit (e.g., from the psychiatric wing to a medical floor, from medical floor to a coronary 
care unit, from neurological floor to a TB unit). 
Hospitalization or prolongation of hospitalization in the absence of a precipitating clinical AE 
is not in itself an SAE. Examples include the following: 
 Admission for treatment of a pre-existing condition not associated with the 
development of a new AE or worsening of the pre-existing condition (e.g., for work-
up of persistent pre-treatment laboratory abnormality) 
 Social admission (e.g., subject has no place to sleep) 
 Administrative admission (e.g., for yearly physical examination) 
 Protocol-specified admission during a study (e.g., for a procedure required by the 
study protocol) 
 Optional admission not associated with a precipitating clinical AE (e.g., for elective 
cosmetic surgery) 
 Hospitalization for observation without a medical AE 
 Hospitalization purely for convenience (e.g., for easier performance of study 
assessments) 

CELLTRION, Inc. 
CT-P17 
Protocol Number CT-P17 1.3

 Pre-planned treatments or surgical procedures; these should be noted in the baseline 
documentation for the entire protocol and/or for the individual subject 
6.2.1.5 Assessment of Severity 
The severity, or intensity, of an AE refers to the extent to which an AE affects the subject’s 
daily activities. The severity of the AE will be graded based on the CTCAE v5.0, based on 
the following general guidelines (a semicolon indicates “or” within each description): 
Grade 1: 
Mild AE (minor; no specific medical intervention; asymptomatic laboratory 
findings only; radiographic findings only; marginal clinical relevance) 
Grade 2: 
Moderate AE (minimal intervention; local intervention; noninvasive 
intervention [packing, cautery]) 
Grade 3: 
Severe and undesirable AE (significant symptoms requiring hospitalization or 
invasive intervention; transfusion; elective interventional radiological 
procedure; therapeutic endoscopy or operation) 
Grade 4: 
Life-threatening or disabling AE (complicated by acute, life-threatening 
metabolic or cardiovascular complications such as circulatory failure, 
hemorrhage, or sepsis; life-threatening physiological consequences; need for 
intensive care or emergent invasive procedure; emergent interventional 
radiological procedure, therapeutic endoscopy, or operation) 
Grade 5: 
Death related to AE 
Changes in the severity of an AE will be documented to allow an assessment of the duration 
of the event at each level of severity to be performed. If an AE upgrades in severity or, 
changes from non-serious to serious, a new AE needs to be reported. If an AE downgrades in 
severity, it should not be reported as a new AE. Adverse events characterized as intermittent 
do not require documentation of onset and duration of each episode. 
6.2.1.6 Assessment of Causality 
As discussed in Section 6.2.1.3, the investigator’s assessment of an AE’s relationship to study 
drug is part of the documentation process, but it is not a factor in determining what is or is not 
reported in the study. If there is any doubt as to whether a clinical observation is an AE, the 
event will be reported.

Page 42 
The relationship or association of study drug in causing or contributing to the AE will be 
characterized using the following classification and criteria: 
Unrelated: 
This relationship suggests that there is no association between the study drug 
and the reported event. 
Possible: 
This relationship suggests that treatment with the study drug caused or 
contributed to the AE, i.e., the event follows a reasonable temporal sequence 
from the time of drug administration or follows a known response pattern to the 
study drug, but could also have been produced by other factors. 
Probable: 
This relationship suggests that a reasonable temporal sequence of the event 
with drug administration exists and, based upon the known pharmacological 
action of the drug, known or previously reported adverse reactions to the drug 
or class of drugs, or judgment based on the investigator’s clinical experience, 
the association of the event with the study drug seems likely. The event 
disappears or decreases on cessation or reduction of the dose of study drug. 
Definite: 
This relationship suggests that a definite causal relationship exists between drug 
administration and the AE, and other conditions (concurrent illness, 
progression/expression of disease state, or concurrent medication reaction) do 
not appear to explain the event. The event reappears or worsens if the study 
drug is re-administered. 
6.2.2 Other Safety Assessments 
6.2.2.1 Immunogenicity Assessment 
Immunogenicity of CT-P17 will be assessed at the time points indicated in the schedule of 
assessments (Table 10-1). 
The immunogenicity of CT-P17 will be assessed at baseline and post-treatment serum 
measures by a validated immunoassay. 
Samples will be drawn before dosing of study drug, at the same time as the clinical laboratory 
tests, where applicable. If the blood sample was unable to be analyzed or was missing, some 
blood samples collected for PK assessment at the same time point could be used for 
immunogenicity assessment. Analysis of the samples will be performed at the bioanalytical 
laboratory.

6.2.2.2 Injection Site Reaction 
Injection site reactions will be assessed 30 minutes (±10 minutes) after study drug 
administration, as specified in the schedule of assessments (Table 10-1).  
Details will be recorded in both the source documents and the eCRF. 
6.2.2.3 Hypersensitivity/Allergic Reactions Monitoring 
Hypersensitivity/allergic reactions will be assessed by additional ECG and vital sign 
monitoring (including systolic and diastolic blood pressure [mmHg], heart rate [beats per 
minute], respiratory rate [breaths per minute], and body temperature [°C]), to monitor for 
possible hypersensitivity/allergic reactions, at the time points indicated in the schedule of 
assessments (Table 10-1). 
In addition, hypersensitivity/allergic reactions will be monitored by routine continuous 
clinical monitoring. In case of hypersensitivity, emergency medication and equipment, such 
as adrenaline, antihistamines, corticosteroids, and respiratory support including inhalational 
therapy, oxygen, and artificial ventilation will be available and an ECG can be performed. 
6.2.2.4 Vital Signs, Weight, and Height 
Vital signs will be measured at the time points indicated in the schedule of assessments 
(Table 10-1). The following vital signs will be measured: systolic and diastolic blood pressure 
(mmHg), heart rate (beats per minute), respiratory rate (breaths per minute), and body 
temperature (°C). Blood pressure and heart rate measurements will be performed after the 
subject has been resting for at least 5 minutes. All measurements will be documented at each 
visit. Details will be recorded in both the source documents and the eCRF. 
Vital sign measurements will also be monitored before and after study drug administration as 
part of the hypersensitivity monitoring (Section 6.2.2.3). 
Body weight and height will be measured according to the schedule of assessments 
(Table 10-1). 
6.2.2.5 Electrocardiogram 
Single 12-lead ECGs will be obtained after the subject has been in the supine position for at 
least 5 minutes at the time points indicated in the schedule of assessments (Table 10-1). 
Electrocardiograms for hypersensitivity monitoring will be performed at 3 hours (±30 
minutes) after the administration of study drug and additional ECGs can be performed if the 

CELLTRION, Inc. 
CT-P17 
Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 44 
subject experiences cardiac symptoms. Either 3-lead or 12-lead ECGs can be used for 
hypersensitivity monitoring. If, following ECG review by the investigator, there are any ECG 
findings that would indicate cardiac insufficiency or QT prolongation, the subject will be 
referred to cardiologist to confirm the abnormality. The investigator will then report the event 
in the source documents and the eCRF. Regardless of the ECG result, further evaluation with 
a cardiologist can be performed depending on the investigator’s discretion. 
6.2.2.6 Physical Examinations 
A standard physical examination will be performed at the time points indicated in the 
schedule of assessments (Table 10-1).  
The physical examination includes an assessment of general appearance and a review of 
systems. Investigators will evaluate subjects for any indication of infections and injection site 
reactions in accordance with the investigator’s medical judgment. 
Information about the physical examinations will be recorded by the investigator or designee 
in both the source documents and the eCRF. Any abnormalities will be recorded in the source 
documents. Clinically significant findings and illnesses reported after the start of the study 
that meet the definition of an AE will be recorded as such in the source documents and eCRF. 
6.2.2.7 Tuberculosis Assessments 
At Screening, subjects with active TB, latent TB (defined as a positive result for IGRA with 
no active lesion in examination of chest X-ray without any sign or symptom of TB), a history 
of TB, had close contact with a person with active TB or traveled to areas within a high 
incidence of TB within 8 weeks prior to the administration of the study drug (Day 1) or has 
plans to travel to the area in which TB is prevalent during the study period will not be 
enrolled in the study. 
Subjects will be monitored for the clinical signs and symptoms of TB throughout the study 
and until the EOS, as specified in the schedule of assessments (Table 10-1); IGRA and chest 
X-ray can be performed at the investigator’s discretion based on the judgment on the signs 
and symptoms of TB monitoring.  
6.2.2.7.1 
Chest X-ray 
A chest X-ray (both posterior–anterior and lateral views) will be performed at Screening as 
indicated in the schedule of assessments (Table 10-1). The results will be read by a qualified 
radiologist to specifically look for evidence of current or previous active or latent TB. The 
findings will be recorded in both the source documents and eCRF. 

CELLTRION, Inc. 
CT-P17 
Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 45 
Radiographic findings suggestive of healed TB or active TB may include, but are not limited 
to, pulmonary nodules, fibrotic scars, calcified granulomas, upper lobe infiltrates, cavitations, 
and pleural effusions. The chest X-ray will be available to the investigator for review and any 
abnormal findings will be discussed with the medical monitor and sponsor before the 
administration of the study drug (Day 1). 
6.2.2.7.2 
Interferon-γ Release Assay 
An IGRA will be performed at Screening and at the time point indicated in the schedule of 
assessments (Table 10-1).  
If the result of IGRA is indeterminate at Screening, retest will be allowed only once during 
the Screening period. If the repeated IGRA result is again indeterminate or positive, the 
subject will be excluded from the study. If the repeated IGRA result is negative, the subject 
may be included in the study. 
If the result of the IGRA is indeterminate after administration of the study drug, one retest 
will be possible. If the repeated IGRA test result is again indeterminate, the investigator will 
discuss and agree with the sponsor or its designee the next action to be taken. 
If the result of the IGRA is positive during the study, subjects will be referred to the clinicians 
immediately to be investigated for the presence of active TB based on medical history and 
any clinical signs and symptoms including chest X-ray result.  
The analysis will be performed at the local laboratory. 
6.2.2.8 Pregnancy 
A serum pregnancy test (-human chorionic gonadotropin) will be performed on women of 
childbearing potential at Screening, Day -1 and EOS visit, as indicated in the schedule of 
assessments (Table 10-1). Only subjects with negative results for both serum pregnancy tests 
at Screening and Day -1 can be enrolled in the study. 
Throughout the study, a serum or urine pregnancy test will be performed when there is any 
possibility of pregnancy, and a confirmatory serum pregnancy test will be performed if a 
urine pregnancy test result is positive.  
In an event of unexpected pregnancy during study participation and for 5 months after 
administration of the study drug, the subjects will be counselled to inform the investigator. If 
a female subject or the partner of a male subject becomes pregnant, the pregnancy must be 
reported to CELLTRION, Inc. and 
 PVG within 24 hours of the study center’s 

CELLTRION, Inc. 
CT-P17 
Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 46 
knowledge of the pregnancy while confirmation is pending. The study center must complete 
the supplied pregnancy form (female subject or partner of a male subject) and return it to 
CELLTRION, Inc. and 
 PVG within 24 hours after acquisition of the consent for the 
pregnancy form. 
Pregnant subjects or the pregnant partners of male subjects will be followed until the end of 
the pregnancy (e.g., delivery, stillbirth, miscarriage) and the mother and the baby will be 
followed for 1 year after the birth, provided consent is obtained. Pregnancy alone will not be 
regarded as an AE unless there is a suspicion that the study drug may have interfered with the 
effectiveness of a contraceptive medication. Elective abortions without complications should 
not be handled as AEs, unless they are therapeutic abortions. Hospitalization for normal 
delivery of a healthy newborn should not be considered as SAE. Any SAE that occurs during 
pregnancy (e.g., maternal serious complications, therapeutic abortion, ectopic pregnancy, 
stillbirth, neonatal death, congenital anomaly, birth defect) must be reported within 24 hours 
in accordance with the procedure for reporting SAEs (Section 6.2.1.4). 
6.2.3 Hepatitis B, Hepatitis C, Human Immunodeficiency Virus and 
Nontreponemal Test 
At Screening, HBsAg, HBsAb, and HBcAb (total or IgG) will be assessed in all subjects 
(mandatory) as specified in the Table 6-1. If a subject has HBsAg negative, HBsAb negative 
or positive, and HBcAb (IgG or total) positive, a hepatitis B virus (HBV) DNA test will be 
performed at Screening and its result will be used to determine the eligibility.

The history of drug abuse, alcohol and nicotine will be checked by medical history taking by 
the Investigator during the Screening period and Baseline (Day -1). 
Creatinine clearance will be calculated using serum creatinine level only at screening for 
inclusion. The result will be considered for inclusion by the discretion of the investigator, and 
it will be recorded on source document and eCRF. Any value outside the normal range will be 
flagged for the attention of the investigator or the sponsor at the study center. The investigator 
will indicate whether or not the value is clinically significant. If the result of the screening is 
indicated as clinically significant abnormal value, the subject will NOT be allowed into the 
study without permission of the sponsor. However, retest is permitted only once during 
screening period by the Investigator’s judgment. Additional testing during the study may be 
performed if medically indicated. If a clinically significant abnormality defined as per 
Section 6.2.1 is found in the samples taken after dosing, during the study, and/or at the EOS 
visit, it should be recorded as an AE and the study subject will be followed up until the test(s) 
has (have) normalized or stabilized. 
6.2.5 Local Site Pain 
Local site pain will be assessed using 100 mm VAS immediately (within 15 minutes) after 
study drug administration (Day 1) according to the schedule of assessments (Table 10-1). 
Subjects will be asked to indicate their current level of pain intensity by drawing a single 
vertical line (│) on the 100 mm line (Appendix 10.2).

7 Statistical Analysis Plan 
The statistical analysis will be performed using 
 
. The statistical methods for this study will be 
described in a detailed statistical analysis plan (SAP), which will be finalized before locking 
of the database. Changes from analyses planned in this protocol will be documented in the 
SAP. Any deviations from the planned analysis as described in the SAP will be justified and 
recorded in the final clinical study report (CSR). 
For categorical variables, frequencies and percentages will be presented. Continuous 
variables will be summarized using descriptive statistics (number of subjects, mean, standard 
deviation [SD], median, minimum, and maximum). 
7.1 Study Population 
7.1.1 Disposition of Subjects 
The number and percentage of subjects entering and completing the clinical study will be 
presented by treatment arm. 
The number of subjects who enroll in the study and the number and percentage of subjects 
who complete the study will be presented. Frequency and percentage of subjects who 
withdraw or discontinue from the study, and the reason for withdrawal or discontinuation, 
will also be summarized. 
7.1.2 Protocol Deviations 
Deviations from the protocol, including deviations of inclusion/exclusion criteria, will be 
defined as “minor” or “major” before database lock. 
7.1.3 
Analysis Populations 
Intent-to-treat (ITT) Population: The ITT population is defined as all subjects enrolled and 
randomly assigned to receive a dose of any study drug, regardless of whether or not any study 
drug dosing was completed. Subjects will be assigned to treatment arms based on 
randomization. 
All study population analyses, including disposition of subjects, protocol deviations, and 
analysis populations as well as demographic and background characteristics will be analyzed 
using the ITT Population. 
Pharmacokinetic Population: The PK population will include subjects who receive a 
complete dose of study drug and provide at least 1 post-treatment serum concentration with a 

CELLTRION, Inc. 
CT-P17 
Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 52 
concentration above the lower limit of quantification. Subjects in the PK population will be 
analyzed according to the treatment they received. 
Safety Population: The safety population will include all randomized subjects who receive a 
complete or partial dose of study drug. Subjects will be assigned to treatment arms based on 
treatment actually received. 
7.2 Pharmacokinetic Analyses 
All PK analyses will be conducted based on the PK population. The primary and secondary 
PK parameters of CT-P17 will be analyzed using non-compartmental methods based on the 
actual sampling time points. All parameters will be calculated using 
 
. 
7.2.1 Primary Pharmacokinetic Analyses 
The primary PK analysis will assess the bioequivalence of CT-P17 SC administration via AI 
versus PFS in terms of the primary PK parameters, AUC0-inf, AUC0-last, and Cmax, 
The primary PK parameters will be presented in data listings and summarized by treatment 
using the following descriptive statistics: number of subjects, mean, SD, median, minimum, 
maximum, geometric mean, and coefficient of variation (CV). Additionally, primary PK 
parameters will be summarized by treatment and anti-drug antibody status. 
For primary endpoints, the statistical analysis of the log-transformed primary endpoints 
(AUC0-inf, AUC0-last, and Cmax) will be based on analysis of covariance (ANCOVA) model 
with treatment as a fixed effect and body weight (≥80 kg vs. <80 kg) as measured on baseline 
(Day -1), gender (male vs. female) and study center as covariates. Point estimates (geometric 
means and ratio of geometric means) will be calculated from back transforming the least 
squares means of the natural log-transformed values of AUC0-inf, AUC0-last, and Cmax and 
difference in the least squares means. The PK of CT-P17 administered via AI and PFS will be 
determined to be equivalent if the 90% CIs for ratios of geometric means of each comparison 
are entirely contained within 80% to 125% for AUC0-inf, AUC0-last, and Cmax. 
7.2.2 Secondary Pharmacokinetic Analyses 
The secondary PK analysis will assess the bioequivalence of CT-P17 SC administration via 
AI versus PFS in terms of serum concentration data and secondary PK parameters.

characteristics will be presented in summary tables. Qualitative data (e.g., medical history) 
will be summarized in contingency tables, and quantitative data (e.g., age) will be 
summarized using quantitative descriptive statistics. 
7.3.2 Adverse Events 
Adverse events will be recorded according to the CTCAE v5.0 and will be coded to system 
organ class (SOC) and preferred term (PT) according to MedDRA. A TEAE is defined as 
described in Section 6.2.1.1. The following AE summaries will be reported by SOC, PT, and 
treatment arm, as appropriate: 
 Number and percentage of subjects reporting at least 1 TEAE 
 Number and percentage of subjects reporting at least 1 treatment-emergent SAE

7.3.8 Prior and Concomitant Medications 
Prior and concomitant medications will be coded using the WHO Drug Dictionary (WHO-
DD). All prior and concomitant medications data will be listed and summarized by treatment 
arm using drug class and PT as appropriate. 
7.4 Sample Size Calculations 
A sample size of 162 (81 subjects from each arm) will provide at least 90% power to show 
similarity in PK of CT-P17 AI and CT-P17 PFS using 90% CI approach based on 80% to 
125% equivalence margin, expected geometric mean ratio of 1.0 and CV of 45%, which is 
assumed based upon historical PK data in healthy subjects. Considering a 10% drop-out rate, 
approximately 180 subjects (90 subjects each treatment arm) will be randomized.  
7.5 Interim Analyses 
No formal interim analyses will be performed in this study. 
7.6 Data Quality Assurance 
This study will be conducted according to the ICH E6 (R2) risk and quality processes 
described in the applicable procedural documents. The quality management approach to be 
implemented in this study will be documented and will comply with the current ICH Good 
Clinical Practice guidelines on quality and risk management. 
Steps to be taken to ensure the accuracy and reliability of data include the selection of 
qualified investigators and appropriate study centers, review of protocol procedures with the 
investigator and associated staff before the study, periodic monitoring visits by CELLTRION, 
Inc. or its designee, and direct transmission of data from a laboratory into the clinical 
database. The eCRFs will be reviewed for accuracy and completeness by the monitor during 
on-site monitoring visits and after their return to CELLTRION, Inc. or its designee; any 
discrepancies will be resolved with the investigator or designees, as appropriate. The data will 
be entered into the clinical study database and verified for accuracy. 
Quality assurance staff from CELLTRION, Inc. or its designee may visit the study center to 
carry out an audit of the study in compliance with regulatory guidelines and company policy. 
Such audits will require access to all study records, including source documents, for 
inspection and comparison with the eCRF. Subject privacy must, however, be respected. 
Sufficient prior notice will be provided to allow the investigator to prepare properly for the 
audit.

8 Investigator’s Obligations 
The following administrative items are meant to guide the investigator in the conduct of the 
study but may be subject to change based on industry and government SOPs, working 
practice documents, or guidelines. Changes will be reported to the IRB/IEC but will not result 
in protocol amendments. 
8.1 Confidentiality 
All laboratory specimens, evaluation forms, reports, and other records will be identified in a 
manner designed to maintain subject confidentiality. All records will be kept in a secure 
storage area with limited access. Clinical information will not be released without the written 
permission of the subject, except as necessary for monitoring and auditing by the sponsor, its 
designee, regulatory authority(ies), or the IRB/IEC. 
The investigator, all employees and coworkers involved with this study may not disclose or 
use for any purpose other than performance of the study, any data, record, or other 
unpublished, confidential information disclosed to those individuals for the purpose of the 
study. Prior written agreement from the sponsor or its designee must be obtained for the 
disclosure of any said confidential information to other parties. 
8.2 Independent Ethics Committee or Institutional Review Board 
Regulatory authority regulations and the ICH guidelines require that approval be obtained 
from an IRB/IEC before participation of human subjects in research studies. Before study 
onset, the protocol, ICF, advertisements to be used for the recruitment of study subjects, and 
any other written information regarding this study to be provided to the subject must be 
approved by the IRB/IEC. Documentation of all IRB/IEC approvals and of the IRB/IEC 
compliance with the ICH harmonised tripartite guideline E6 (R2): Good Clinical Practice 
guidelines will be maintained by the site and will be available for review by the sponsor or its 
designee. 
All IRB/IEC approvals will be signed by the IRB/IEC chairman or designee and must 
identify the IRB/IEC name and address, the clinical protocol by title or protocol number or 
both and the date approval or a favorable opinion was granted. 
The investigator is responsible for providing written summaries of the progress and status of 
the study at intervals not exceeding 1 year or otherwise specified by the IRB/IEC. The 
investigator must promptly supply the sponsor or its designee, the IRB/IEC, and, where 
applicable, the institution, with written reports on any changes significantly affecting the 
conduct of the study or increasing the risk to subjects.

8.3 Subject Information and Consent 
Written informed consent in compliance with local regulatory authority requirements shall be 
obtained from each subject before he or she enters the study or before performing any 
unusual or nonroutine procedure that involves risk to the subject. If any institution-specific 
modifications to study-related procedures are proposed or made by the site, the consent will 
be reviewed by the sponsor or its designee or both before IRB/IEC submission. Once 
reviewed, the investigator will submit the ICF to the IRB/IEC for review and approval before 
the start of the study. If the ICF is revised during the course of the study, all active 
participating subjects must sign and date the revised form. 
Before recruitment and enrollment, each prospective subject will be given a full explanation 
of the study and be allowed to read the approved ICF. Once the investigator is assured that 
the subject understands the implications of participating in the study, the subject will be asked 
to give his or her consent to participate in the study by signing the ICF. A copy of the ICF will 
be provided to the subject. 
8.4 Financial Disclosure and Obligations 
The investigator is required to provide financial disclosure information to allow the sponsor 
to submit the complete and accurate certification or disclosure statements required under 
local regulations. In addition, the investigator must provide to the sponsor a commitment to 
promptly update this information if any relevant changes occur during the course of the 
investigation and for 1 year following the completion of the study. 
Neither the sponsor nor 
 is financially responsible for further testing or treatment of any 
medical condition that may be detected during the screening process. In addition, in the 
absence of specific arrangements, neither the sponsor nor 
 is financially responsible for 
further treatment of the subject’s disease. 
8.5 Investigator Documentation 
Prior to beginning the study, the investigator will be asked to comply with ICH E6 (R2) 8.2 
and local regulations by providing the following essential documents, including but not 
limited to: 
 IRB/IEC approval, 
 An original investigator-signed investigator agreement page of the protocol,

Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 59 
 Curriculum vitae for the principal investigator and each sub-investigator listed on Form 
FDA 1572. Current licensure must be noted on the curriculum vitae. Curriculum vitae 
will be signed and dated by the principal investigators and sub-investigators at study 
start-up, indicating that they are accurate and current, 
 Financial disclosure information to allow the sponsor to submit complete and accurate 
certification or disclosure statements required under local regulations. In addition, the 
investigators must provide to the sponsor a commitment to promptly update this 
information if any relevant changes occur during the course of the investigation and for 
1 year after the completion of the study, 
 An IRB/IEC-approved ICF, samples of site advertisements for recruitment for this study, 
and any other written information about this study that is to be provided to the subject or 
legal guardians, and 
 Laboratory certifications and reference ranges for any local laboratories used by the site, 
in accordance with local regulations. 
8.6 Study Conduct 
The investigator agrees to perform all aspects of this study in accordance with the ethical 
principles that have their origin in the Declaration of Helsinki, ICH E6 (R2): Good Clinical 
Practice, the protocol, and all national, state, and local laws or regulations. 
8.7 Data Collection 
8.7.1 
Electronic Case Report Forms and Source Documents 
It is the intent of this study to acquire study data via electronic format. As part of the 
responsibilities assumed by participating in the study, the principal investigator or 
sub-investigator agrees to maintain adequate case histories for the subjects treated as part of 
the research under this protocol. The principal investigator or sub-investigator agrees to 
maintain source documentation (e.g., laboratory reports), enter subject data into the eCRF as 
accurately as possible, and respond to any reported discrepancies rapidly. These source 
documents may include diaries, laboratory reports, ECG strips, etc. 
The analysis data sets will be a combination of these data and data from other sources 
(e.g., laboratory data). 
The eCRFs are accessed through the appropriate system, which allows for on-site data entry 
and data management. Study center users can read from and write to the sponsor’s database 

CELLTRION, Inc. 
CT-P17 
Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 60 
where the clinical data are collected. This provides immediate, direct data transfer to the 
database, as well as immediate detection of discrepancies, enabling study center coordinators 
to resolve and manage discrepancies in a timely manner. 
Each study center staff involved with the study at each study center will have an individual 
logon and password that allow for record traceability. Thus, the system, and subsequently any 
investigative reviews, can identify coordinators, investigators, and individuals who have 
entered or modified records. 
8.8 Adherence to Protocol 
The investigator agrees to conduct the study as outlined in this protocol in accordance with 
ICH E6 (R2) and all applicable guidelines and regulations. 
8.9 Adverse Events and Study Report Requirements 
By participating in this study, the investigator agrees to submit reports of SAEs according to 
the timeline and method outlined in the protocol. In addition, the investigator agrees to 
submit annual reports to his or her IRB/IEC as appropriate. If required by applicable local 
regulations, the investigator shall promptly notify the relevant IRB/IEC (in addition to the 
sponsor) of any SAE (including follow-up SAEs) and SUSARs that occurred at his/her site. 
He/she shall verify that the IRB/IEC acknowledges receipt of the information. The 
investigator also agrees to provide the sponsor with an adequate report, if applicable, shortly 
after completion of the investigator’s participation in the study. 
8.10 Investigator’s Final Report 
Upon completion of the study, the investigator, where applicable, will inform the institution; 
the investigator/institution will provide the IRB/IEC with a summary of the study’s outcome, 
and the sponsor and regulatory authority(ies) with any reports required. 
8.11 Records Retention 
All correspondence (e.g., with sponsor, IRB/IEC, or clinical research associates) relating to 
this clinical study will be kept in appropriate file folders. Records of subjects, source 
documents, eCRFs, and drug inventory sheets pertaining to the study must be kept on file. 
Essential documents will be retained until at least 15 years after the date on which the results 
of the study are submitted to the regulatory authorities in support of an allocation for a 
research or marketing permit, or completion date for study by approval or disapproval of any 
application, whichever is later. These documents will be retained for a longer period, 
however, if required by the applicable regulatory requirements or by an agreement with the 

CELLTRION, Inc. 
CT-P17 
Protocol Number CT-P17 1.3 
Protocol Version 2.0 
 
Page 61 
sponsor. It is the sponsor’s responsibility to inform the investigator/institution as to when 
these documents no longer need to be retained. 
If an investigator moves, withdraws from an investigation, or retires, the responsibility for 
maintaining the records may be transferred to another person, who will accept the 
responsibility. Notice of transfer is recommended to be made and agreed upon by the sponsor. 
8.12 Subject Identification Register 
The investigator agrees to complete a subject identification register, which will be used for 
the purpose of long-term follow-up, if needed. This form will be treated as confidential and 
will be filed by the investigator in the Study Center Master File. Otherwise, all reports and 
communications relating to the study will identify subjects by assigned number only. 
8.13 Publications 
After completion of the study, the data may be considered for reporting at a scientific meeting 
or for publication in a scientific journal. In these cases, the sponsor will be responsible for 
these activities and may work with the investigators to determine how the manuscript is 
written and edited, the number and order of authors based on SOPs of CELLTRON, Inc., the 
publication to which it will be submitted, and any other related issues. The sponsor has final 
approval authority over all such issues. 
Data are the property of the sponsor and cannot be published without their prior 
authorization, but data and any publication thereof will not be unduly withheld.

9.1 Analytical Facilities 
Any analytical facilities and procedures utilized for this study must be Good Laboratory 
Practice compliant. The following analytical facility will be used: 
 
 
 
 
 
9.2 Monitoring 
9.2.1 
Data and Safety Monitoring Board 
An independent data and safety monitoring board will not be used for this study.  
9.2.2 
Monitoring of the Study 
The clinical monitor, as a representative of the sponsor, is obligated to follow the study 
closely. In doing so, the monitor will visit the investigator and study center at periodic 
intervals in addition to maintaining necessary telephone and email contact. The monitor will 
maintain current personal knowledge of the study through observation, review of study 
records and source documentation, and discussion of the conduct of the study with the 
investigator and staff.

9.3 Management of Protocol Amendments and Deviations 
9.3.1 
Modification of the Protocol 
Before the beginning of the study, the clinical study protocol and other relevant documents 
will be approved by the IRB/IEC, in accordance with local legal requirements. The sponsor 
must ensure that all ethical and legal requirements have been met before the first subject is 
enrolled in the study. 
This protocol must be followed exactly. To change the protocol, amendments must be written, 
which must be released by the responsible staff and receive IRB/IEC approval prior to 
implementation as appropriate. 
9.3.2 
Protocol Deviations 
The investigator or designee will document and explain in the subject’s source documentation 
any deviation from the approved protocol. The investigator may implement a deviation from, 
or a change to, the protocol to eliminate an immediate hazard to study subjects without prior 
IRB/IEC approval. As soon as possible after such an occurrence, the implemented deviation 
or change, the reasons for it, and any proposed protocol amendments will be submitted to the 
IRB/IEC for review and approval, to the sponsor for agreement, and to the regulatory 
authorities, if required. 
A deviation from the protocol is an unintended or unanticipated departure from the 
procedures or processes approved by the sponsor and the IRB/IEC and agreed to by the 
investigator. A significant deviation occurs when there is nonadherence to the protocol by the 
subject or investigator that results in a significant and additional risk to the subject’s rights, 
safety and well-being. Significant deviations can include nonadherence to inclusion or 
exclusion criteria, or nonadherence to a regulatory agency’s regulations or ICH Good Clinical 
Practice guidelines, and will lead to the subject being withdrawn from the study (Section 4.3). 
Protocol deviations will be documented by the clinical monitor throughout the course of 
monitoring visits. The investigator will be notified in writing by the monitor of deviations. 
The IRB/IEC will be notified of all protocol deviations, if appropriate, in a timely manner. 
9.4 Study Termination 
Although the sponsor has every intention of completing the study, they reserve the right to 
discontinue it at any time for clinical or administrative reasons. 
The end of the study is defined as the date on which the final database is locked.

1. 
During the screening period, retest for screening is permitted only once by the Investigator’s judgment. If the repeated test result is again not suitable or indeterminate for 
inclusion, the subject will be screen failed. 
2. 
Subjects will be confined to the study center until completion of the 48-hour assessments after the administration of the study drug (Day 1) and admission can be extended 
depending on the subject’s and study center’s availability. The consecutive study visits will be carried out on an out-patient basis. 
3. 
All EOS assessments will be performed on Day 71, for all subjects including those who discontinued prematurely. 
4. 
Inclusion and exclusion criteria should be confirmed before Day -1. On the Day -1, recheck process will be performed. 
5. 
Height will be measured at Screening only. 
6. 
Serology tests will be performed at the Screening visit for anti-HIV (HIV-1 and HIV-2) antibodies, hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), 
hepatitis B core antibody (HBcAb [total or IgG]), HBV DNA (if subject has HBsAg negative, HBsAb negative or positive, and HBcAb positive), hepatitis C antibody (HCAb), 
and nontreponemal (e.g., Rapid Plasma Reagin) tests.  
7. 
At Screening, a chest X-ray, an IGRA, and signs and symptoms of TB clinical monitoring will be performed. If the result of IGRA is indeterminate at Screening, a retest will 
be allowed only once during the Screening period. Additional IGRA test and chest X-ray will be performed if symptoms raise a suspicion of TB upon the judgement of the 
investigator during the study and until the EOS. Only IGRA will be performed at the EOS visit; signs and symptoms of TB clinical monitoring will be performed throughout 
the study and until the EOS. 
8. 
A serum pregnancy test on women of childbearing potential will be performed at Screening, Day -1 and the EOS visit. Throughout the study, a serum or urine pregnancy test 
will be performed when there is any possibility of pregnancy, and a confirmatory serum pregnancy test will be performed if a urine pregnancy test result is positive. 
9. 
Urine drug screen (tetrahydrocannabinol, opiates, cocaine, methamphetamine, barbiturates and benzodiazepines) and history check by the investigator will be performed for 
drug abuse, alcohol, and nicotine in Screening and Day -1. 
10. Clinical laboratory tests will be carried out: Hematology (hematocrit, hemoglobin, red blood cell count, white blood cell count with differential, absolute neutrophil count, 
platelets), Serum chemistry (albumin, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, calcium, chloride, total cholesterol, 
creatine phosphokinase, creatinine, creatine kinase–myocardial band isoenzyme [CK-MB], creatinine clearance [estimated by weight and by Cockcroft-Gault formula], C-
reactive protein, gamma-glutamyl transferase, glucose, lactate dehydrogenase, magnesium, potassium, sodium, total bilirubin, total protein, uric acid, direct bilirubin, 
triglycerides, inorganic phosphorus, high-density lipoprotein cholesterol, Troponin I), Urinalysis (color, pH, specific gravity, ketones, protein, glucose, bilirubin, nitrite, 
urobilinogen, occult blood, and microscopic examination). Creatinine clearance will be calculated using serum creatinine level only at screening for inclusion. 
11. Vital sign measurement on Day 1 will be performed before the start of the study drug administration (within 30 minutes). Additional vital signs will be measured after the study 
drug administration. On Day 1 (pre-dose) and Day 2, the vital signs measurement may be considered as a part of hypersensitivity monitoring and only either one will be recorded 
in the eCRF.  
12. The study drug will be administered on the subject’s lower abdomen except for the 5 cm around the subject’s navel. 
13. Samples for pharmacokinetic analysis will be obtained at the following time points: 
PK sampling time points 
Day 1 Pre-dose (within 60 minutes prior to administration of the study drug) 
Day 1 (6 hours after the administration of the study drug); ±15 minutes 
Day 1 (12 hours after the administration of the study drug); ±1 hour 
Day 2 (24 hours after the administration of the study drug); ±2 hours 
Day 3, 4, 5, 5.5, 6, 6.5, 7, 8, and 9 (48, 72, 96, 108, 120, 132, 144, 168, and 192 hours, respectively, after the 
administration of the study drug); ±2 hours

Day 15 and 22 (336 and 504 hours, respectively, after the administration of the study drug); ±4 hours  
Day 29, 43, 57, and 71 (i.e., EOS) after the administration of the study drug; ±1 day 
14. Sample for immunogenicity analysis on Day 1 will be performed prior to the study drug administration within 60 minutes. 
15. For hypersensitivity monitoring, vital sign measurements will be performed before the start of the study drug administration (within 15 minutes) and at 3, 6, 12, and 24 hours 
after administration on Day 1. The tolerance window is ±30 minutes for 3 and 6 hours, and ±60 minutes for 12 and 24 hours after the administration. Either 3-lead or 12-lead 
ECG can be used at 3 hours (±30 minutes) after the administration of the study drug on Day 1 and additional ECG can be performed if a subject experiences cardiac symptoms. 
Emergency equipment, such as adrenaline, antihistamines, corticosteroids, and respiratory support (inhalational therapy, oxygen and artificial ventilator) must be available. 
16. Injection site reaction will be assessed 30 minutes (±10 minutes) after the study drug administration. 
17. Local site pain will be observed using 100 mm VAS immediately (within 15 minutes) after the study drug administration. 
18. Use of all prior and concomitant medications, from within 30 days prior to the administration of the study drug (Day 1) until the last assessment date or EOS visit, will be 
recorded. 
19. Adverse events (and serious adverse events) should be reported until the EOS visit, regardless of the relationship to the study drug.
