Study Period (Day 1 [Week 1] to Day 98 [Week 14]): 
CT-P16, EU-approved Avastin, or US-licensed Avastin will be administered to 
subjects on Day 1. Subjects will be confined to the clinical unit until completion 
of the 24-hour assessments after IMP administration. The consecutive study visits 
will be carried out on an out-patient basis. Acceptable tolerance windows for each 
assessments are described in Section 7.1. 
• PK analysis will be collected at pre-dose, at the end of infusion (EOI), 1 hour 
after the EOI, and at 4, 8, 12, and 24 hours (Day 2) after start of infusion 
(SOI), and on Days 3, 4, 8, 15, 29, 43, 57, 71, and 85.  
• Clinical laboratory testing will be performed on Day 3, 8, 15, 43, and 71. 
• Vital signs will be measured before dosing on Day 1, and on Day 3, 4, 8, 15, 
29, 43, 57, 71 and 85.  
• A 12-lead ECG will be performed on Day 3, 8, 15, 43, and 71.  
• Physical examinations will be performed on Day 3.  
• Hypersensitivity monitoring (vital signs measurement and 12-lead ECG) will 
be done on Day 1. 
• Immunogenicity of CT-P16, EU-approved Avastin and US-licensed Avastin 
will be assessed at pre-dose on Day 1, Day 15, 43 and Day 71. 
 
End-of-Study Visit (Day 99 [Week 15]): 
The end-of-study visit will be performed on Day 99 (Week 15).  
Subjects will return to the research unit and undergo the following PK and safety 
assessments: PK sampling and immunogenicity for CT-P16, EU-approved Avastin 
and US-licensed Avastin, collection of information related to AEs and concomitant 
medications, body weight, vital signs, 12-lead ECG, clinical laboratory tests and 
physical examination. 
The total duration of the participation will be up to 15 weeks for each individual 
subject who completes the entire clinical trial. 
Criteria for Evaluation: 
Primary Endpoints 
Pharmacokinetics  
• 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 
Pharmacokinetics 
• Time to Cmax (Tmax) 
• Volume of distribution during the terminal phase (Vz) 
• Terminal elimination rate constant (λz) 
• Terminal half-life (t1/2) 
• Total body clearance (CL)  
• Percentage of AUC0-inf obtained by extrapolation (%AUCext) 
Safety and Immunogenicity 
• Vital signs (blood pressure [BP], heart rate [HR], body temperature [BT], and 
respiratory rate [RR]) 
• Physical examination

• Clinical laboratory tests including hematology, chemistry, coagulation, and 
urinalysis 
• Twelve-lead electrocardiogram (ECG) 
• AEs and concomitant medication 
• Adverse event of Special interest (AESI) (e.g., hypersensitivity/infusion-
related reaction)  
• Immunogenicity of CT-P16, EU-approved Avastin and US-licensed Avastin 
Sample size 
assumption: 
A sample size of 42 completing subjects from each arm of the clinical study will 
provide 90% power to show similarity in PKs among the test product, EU-
approved Avastin and US-licensed Avastin using 90% confidence interval (CI) 
approach based on 80%-125% equivalence margin. A coefficient of variation (CV) 
of 30% is assumed based upon historical PK data. The sample size is calculated 
from two one-sided tests with each 5% significance level using geometric mean 
ratio. A 10% dropout rate is anticipated so approximately 141 subjects (47 in each 
arm) will be enrolled. By assuming that EU-approved Avastin and US-licensed 
Avastin are identical, the multiplicity problem is not considered in the calculation 
of the sample size. 
Statistical Methods: 
Pharmacokinetic analyses 
The statistical analysis of the log-transformed primary endpoints (AUC0-inf, AUC0-
last and Cmax) will be based on an analysis of covariance (ANCOVA) model. The 
difference in least squares means between the CT-P16 and EU-approved Avastin, 
CT-P16 and US-licensed Avastin, EU-approved Avastin and US-licensed Avastin, 
and the associated 90% CIs will be determined. Back transformation will provide 
the ratio of geometric means and 90% CIs for these ratios.  
Similarity of systemic exposure (AUC0-inf, AUC0-last and Cmax) will be determined 
if 90% CI for the ratio of geometric means is within the acceptance interval of 80% 
to 125% for the following comparisons: 
• CT-P16 vs EU-approved Avastin 
• CT-P16 vs US-licensed Avastin 
• EU-approved Avastin vs US-licensed Avastin 
For secondary endpoints, following PK parameters will be assessed: 
Time to Cmax (Tmax), volume of distribution during the terminal phase (Vz), 
terminal elimination rate constant (λz), terminal half-life (t1/2), total body clearance 
(CL) and percentage of AUC0-inf obtained by extrapolation (%AUCext). 
Pharmacokinetic parameters will be presented in listings and summarized in tables. 
The tables will display the following descriptive statistics: n, mean, median, 
standard deviation (SD), minimum, maximum, the geometric mean and CV. 
Safety and immunogenicity analyses 
All safety and immunogenicity analyses will be conducted on the safety 
population, and listed and summarized by treatment group. All reported terms for 
AEs will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA). Terminology and severity grading of AEs will be recorded based on 
Common Terminology Criteria for Adverse Events (CTCAE) Version 4.03. Prior 
and concomitant medications will be coded using the World Health Organization 
(WHO) Drug Dictionary. All safety data will be analyzed descriptively.

INTRODUCTION 
1.1 
Background 
Vascular endothelial growth factor (VEGF), a diffusible glycoprotein produced by normal and 
neoplastic cells, is an important regulator of physiologic and pathologic angiogenesis (Ferrara 
et al. 2003). It is a highly conserved, homodimeric, heparin-binding glycoprotein that exists in 
several isoforms (Ferrara et al. 1997). VEGF mediates its effects by interacting with the 
membrane-bound tyrosine kinase receptors, VEGFR-1 (Flt-1) and VEGFR-2 (KDR, flk-1), 
activating specific downstream survival and proliferation pathways. VEGF is considered 
essential for normal developmental vasculogenesis, and there is substantial evidence 
implicating VEGF as a critical factor in tumor angiogenesis (Ferrara et al. 2003). Transfection 
of Chinese hamster ovary cells with expression vectors encoding VEGF allows these cells to 
form tumors in nude mice (Ferrara et al. 1993). Increased VEGF expression has been described 
in most human tumors and in many instances is correlated with an adverse prognosis (increased 
risk of tumor recurrence and metastasis and decreased survival) (Takahashi et al. 1995; 
Takahashi et al. 1997; Warren et al. 1995). 
Bevacizumab is a humanized monoclonal antibody directed against VEGF. Bevacizumab binds 
VEGF and prevents the interaction of VEGF to its receptors (Flt-1 and KDR) on the surface of 
endothelial cells. The interaction of VEGF with its receptors leads to endothelial cell 
proliferation and new blood vessel formation in in vitro models of angiogenesis. By blocking 
the endothelial interaction of VEGF and its receptors, bevacizumab serves as an antiangiogenic 
agent. 
The reference product, Avastin, is formulated as a 25 mg/mL concentrate for solution for 
infusion, presented in single-use, type 1 glass vials containing 100 mg or 400 mg of 
bevacizumab. The Avastin drug product is a clear to slightly opalescent, colourless to pale 
brown liquid containing the excipients, α, α-trehalose dihydrate (60 mg/ml), sodium phosphate 
(51 mM, pH 6.2), polysorbate 20 (0.04%), and water for injections. The product is to be diluted 
in 0.9% sodium chloride solution prior to administration. 
CT-P16, containing the active ingredient bevacizumab, is being developed as a similar 
biological medicinal product to Avastin, which currently has received approval in both 
European Union (EU) and United States (US) for the indications shown in the Avastin 
Summary of Product Characteristics (SmPC, 2017) and Avastin United States Prescribing 
Information (USPI, 2016). 
CT-P16 drug product will have the same pharmaceutical form and strength as the EU-
approved/US-licensed Avastin, and is intended to be highly analytically comparable to EU-
approved/US-licensed Avastin. As for EU-approved/US-licensed Avastin, the bevacizumab

active ingredient of CT-P16 is produced by recombinant DNA technology in a CHO cell 
expression system and purified by a suitable process. 
Avastin has been approved in a variety of tumor types, including metastatic carcinoma of the 
colon or rectum; metastatic breast cancer (mBC) (EU only); unresectable, advanced, metastatic, 
or recurrent non-small cell lung cancer (NSCLC) other than predominantly squamous histology; 
advanced and/or metastatic renal cell cancer; epithelial ovarian, fallopian tube or primary 
peritoneal cancer; persistent, recurrent, or metastatic carcinoma of the cervix; and glioblastoma 
(US only). 
As CT-P16 is being developed under a global development plan, the pharmacokinetic (PK) 
profile of CT-P16 and two reference products from different sources (EU-approved Avastin 
and US-licensed Avastin) will be compared to demonstrate PK equivalence in this Phase 1 
study. 
1.2 
Rationale for the Clinical 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 clinical study is to compare the PK, safety, tolerability and immunogenicity of the 
proposed biosimilar test product CT-P16 with EU-approved Avastin and US-licensed Avastin 
after a single intravenous (IV) infusion of 5 mg/kg of each product to healthy adult subjects 
following the recommendations of the Food and Drug Administration (FDA) guidance 
“Scientific Considerations in Demonstrating Biosimilarity to a Reference Product (FDA 2015)” 
and EMA guidance “Similar biological medicinal products containing monoclonal antibodies: 
non-clinical and clinical issues” (EMA/CHMP/BMWP/403543/2010) (CHMP 2012). 
With regards to the selection of dose, doses of Avastin between 5 and 15 mg/kg are used in 
clinical practice. From a safety perspective, it is considered best to administer the lowest 
recommended therapeutic dose in studies of healthy subjects. Also, the 5 mg/kg dose is 
proposed in this Phase 1 PK study, since bevacizumab PK is linear at doses between 1 and 10 
mg/kg and use of 5 mg/kg is further supported in terms of assessment of immunogenicity as 
higher doses are theoretically expected to be less immunogenic. According to clinicaltrials.gov, 
5 mg/kg has been administered to healthy male volunteers in another study of a biosimilar 
bevacizumab (Pfizer’s PF-06439535) and has been shown to be well tolerated, with no signs 
of unexpected side effects or cardiotoxicity (Knight et al. 2016). 
Healthy subjects have been selected for this study in order to avoid potentially high variability 
of the exposure of bevacizumab if administered to patients with metastatic colorectal cancer or 
non-squamous non-small cell lung cancer, which would introduce a bias into the attainment of

the primary study objective. A parallel-group design will be used in this study to prevent 
potential crossover effects. 
1.3 
Risk-Benefit Assessment 
Information about the risk following the administration of bevacizumab was taken from the 
Avastin SmPC (2017) and Avastin USPI (2016) of EU-approved and US-licensed Avastin. 
Gastrointestinal (GI) perforations and Fistulae: Patients may be at an increased risk for the 
development of gastrointestinal perforation and gall bladder perforation when treated with 
Avastin. Intra-abdominal inflammatory process may be a risk factor for gastrointestinal 
perforations in patients with metastatic carcinoma of the colon or rectum, therefore, caution 
should be exercised when treating these patients. Prior radiation is a risk factor for GI 
perforation in patients treated for persistent, recurrent or metastatic cervical cancer with 
Avastin and all patients with GI perforation had a history of prior radiation. Therapy should be 
permanently discontinued in patients who develop gastrointestinal perforation. 
Non-GI Fistulae: Patients may be at increased risk for the development of fistulae when 
treated with Avastin. Avastin should be permanently discontinued in patients with 
tracheoesophageal fistula or any Grade 4 fistula [US National Cancer Institute - Common 
Terminology Criteria for Adverse Events (CTCAE) Version 3)]. Limited information is 
available on the continued use of Avastin in patients with other fistulae. In cases of internal 
fistula not arising in the gastrointestinal tract, discontinuation of Avastin should be considered. 
Wound healing complications: Avastin may adversely affect the wound healing process. 
Serious wound healing complications, including anastomotic complications, with a fatal 
outcome have been reported. Therapy should not be initiated for at least 28 days following 
major surgery or until the surgical wound is fully healed. In patients who experienced wound 
healing complications during therapy, treatment should be withheld until the wound is fully 
healed. Therapy should be withheld for elective surgery. Necrotising fasciitis, including fatal 
cases, has rarely been reported in patients treated with Avastin. This condition is usually 
secondary to wound healing complications, gastrointestinal perforation or fistula formation. 
Avastin therapy should be discontinued in patients who develop necrotising fasciitis, and 
appropriate treatment should be promptly initiated. 
Hypertension: An increased incidence of hypertension was observed in Avastin-treated 
patients. Clinical safety data suggest that the incidence of hypertension is likely to be dose-
dependent. Pre-existing hypertension should be adequately controlled before starting Avastin 
treatment. There is no information on the effect of Avastin in patients with uncontrolled 
hypertension at the time of initiating therapy. Monitoring of blood pressure (BP) is generally 
recommended during therapy. In most cases hypertension was controlled adequately using

standard antihypertensive treatment appropriate for the individual situation of the affected 
patient. The use of diuretics to manage hypertension is not advised in patients who receive a 
cisplatin-based chemotherapy regimen. Avastin should be permanently discontinued if 
medically significant hypertension cannot be adequately controlled with antihypertensive 
therapy, or if the patient develops hypertensive crisis or hypertensive encephalopathy. 
Posterior Reversible Encephalopathy Syndrome (PRES): There have been rare reports of 
Avastin-treated patients developing signs and symptoms that are consistent with PRES, a rare 
neurologic disorder, which can present with the following signs and symptoms among others: 
seizures, headache, altered mental status, visual disturbance, or cortical blindness, with or 
without associated hypertension. A diagnosis of PRES requires confirmation by brain imaging, 
preferably magnetic resonance imaging (MRI). In patients developing PRES, treatment of 
specific symptoms including control of hypertension is recommended along with 
discontinuation of Avastin. The safety of reinitiating Avastin therapy in patients previously 
experiencing PRES is not known. 
Proteinuria: Patients with a history of hypertension may be at increased risk for the 
development of proteinuria when treated with Avastin. There is evidence suggesting that all 
Grade (CTCAE Version 3) proteinuria may be related to the dose. Monitoring of proteinuria 
by dipstick urinalysis is recommended prior to starting and during therapy. Therapy should be 
permanently discontinued in patients who develop Grade 4 proteinuria (nephrotic syndrome) 
(CTCAE Version 3). 
Arterial thromboembolism: In clinical trials, the incidence of arterial thromboembolic 
reactions including cerebrovascular accidents, transient ischaemic attacks and myocardial 
infarctions was higher in patients receiving Avastin in combination with chemotherapy 
compared to those who received chemotherapy alone. Patients receiving Avastin plus 
chemotherapy, with a history of arterial thromboembolism, diabetes or age greater than 65 
years have an increased risk of developing arterial thromboembolic reactions during therapy. 
Caution should be taken when treating these patients with Avastin. Therapy should be 
permanently discontinued in patients who develop arterial thromboembolic reactions. 
Venous thromboembolism: Patients may be at risk of developing venous thromboembolic 
reactions, including pulmonary embolism under Avastin treatment. Patients treated for 
persistent, recurrent, or metastatic cervical cancer with Avastin in combination with paclitaxel 
and cisplatin may be at increased risk of venous thromboembolic events. Avastin should be 
discontinued in patients with life-threatening (Grade 4) thromboembolic reactions, including 
pulmonary embolism (CTCAE Version 3). Patients with thromboembolic reactions ≤ Grade 3 
need to be closely monitored (CTCAE Version 3).

Haemorrhage: Patients treated with Avastin have an increased risk of haemorrhage, especially 
tumor-associated haemorrhage. Avastin should be discontinued permanently in patients who 
experience Grade 3 or 4 bleeding during Avastin therapy (CTCAE Version 3). Patients with 
untreated central nervous system (CNS) metastases were routinely excluded from clinical trials 
with Avastin, based on imaging procedures or signs and symptoms. Therefore, the risk of CNS 
haemorrhage in such patients has not been prospectively evaluated in randomized clinical trials. 
Patients should be monitored for signs and symptoms of CNS bleeding, and Avastin treatment 
discontinued in cases of intracranial bleeding. There is no information on the safety profile of 
Avastin in patients with congenital bleeding diathesis, acquired coagulopathy or in patients 
receiving full dose of anticoagulants for the treatment of thromboembolism prior to starting 
Avastin treatment, as such patients were excluded from clinical trials. Therefore, caution 
should be exercised before initiating therapy in these patients. However, patients who 
developed venous thrombosis while receiving therapy did not appear to have an increased rate 
of Grade 3 or above bleeding when treated with a full dose of warfarin and Avastin 
concomitantly (CTCAE Version 3). 
Pulmonary haemorrhage/haemoptysis: Patients with non-small cell lung cancer treated with 
Avastin may be at risk of serious, and in some cases fatal, pulmonary haemorrhage 
/haemoptysis. Patients with recent pulmonary haemorrhage/haemoptysis (> 2.5 mL of red 
blood) should not be treated with Avastin.  
Congestive heart failure (CHF): Reactions consistent with CHF were reported in clinical trials. 
The findings ranged from asymptomatic declines in left ventricular ejection fraction to 
symptomatic CHF, requiring treatment or hospitalization. Caution should be exercised when 
treating patients with clinically significant cardiovascular disease such as pre-existing coronary 
artery disease, or congestive heart failure with Avastin. Most of the patients who experienced 
CHF had mBC and had received previous treatment with anthracyclines, prior radiotherapy to 
the left chest wall or other risk factors for CHF were present. CHF Grade 3 or higher reactions 
were somewhat more frequent among patients receiving bevacizumab in combination with 
chemotherapy than in patients receiving chemotherapy alone. This is consistent with results in 
patients in other studies of mBC who did not receive concurrent anthracycline treatment 
(CTCAE Version 3). 
Neutropenia and infections: Increased rates of severe neutropenia, febrile neutropenia, or 
infection with or without severe neutropenia (including some fatalities) have been observed in 
patients treated with some myelotoxic chemotherapy regimens plus Avastin in comparison to 
chemotherapy alone. This has mainly been seen in combination with platinum- or taxane-based 
therapies in the treatment of NSCLC, mBC, and in combination with paclitaxel and topotecan 
in persistent, recurrent, or metastatic cervical cancer.

Hypersensitivity reactions/infusion reactions: Patients may be at risk of developing 
infusion/hypersensitivity reactions. Close observation of the patient during and following the 
administration of bevacizumab is recommended as expected for any infusion of a therapeutic 
humanized monoclonal antibody. If a reaction occurs, the infusion should be discontinued and 
appropriate medical therapies should be administered. A systematic premedication is not 
warranted. 
Osteonecrosis of the jaw (ONJ): Cases of ONJ have been reported in cancer patients treated 
with Avastin, the majority of whom had received prior or concomitant treatment with 
intravenous bisphosphonates, for which ONJ is an identified risk. Caution should be exercised 
when Avastin and intravenous bisphosphonates are administered simultaneously or 
sequentially. Invasive dental procedures are also an identified risk factor. A dental examination 
and appropriate preventive dentistry should be considered prior to starting the treatment with 
Avastin. In patients who have previously received or are receiving intravenous 
bisphosphonates invasive dental procedures should be avoided, if possible. 
Ovarian failure/fertility: Avastin may impair female fertility. Therefore fertility preservation 
strategies should be discussed with women of child-bearing potential prior to starting treatment 
with Avastin. 
Embryo-fetal Toxicity: Avastin may cause fetal harm based on the drug’s mechanism of action 
and findings from animal studies. Congenital malformations were observed with the 
administration of bevacizumab to pregnant rabbits during organogenesis every 3 days at a dose 
as low as a clinical dose of 10 mg/kg. Furthermore, animal models link angiogenesis and VEGF 
and VEGF Receptor 2 (VEGFR2) to critical aspects of female reproduction, embryo-fetal 
development, and postnatal development. Advise pregnant women of the potential risk to a 
fetus. Advise females of reproductive potential to use effective contraception during treatment 
with and for 6 months after the last dose of Avastin. 
This study will therefore include close monitoring of safety and toxicity reactions. Subjects 
who received monoclonal antibody or biologic agent within 3 months prior to the 
administration of the Investigational medicinal product (IMP) (in a clinical trial or as treatment) 
will be excluded from study participation as they may have developed antibodies against 
bevacizumab, which might be a trigger adverse reaction. Antibodies against bevacizumab may 
also interfere with the primary study objective as the exposure to the IMP may be precluded 
due to antibody binding and therefore may distort the PK endpoints. Further, the potential 
immunogenicity of CT-P16, EU-approved and US-licensed Avastin will be evaluated. 
The safety monitoring practices employed by this protocol are adequate to protect the subjects’ 
safety and should detect all expected treatment-emergent adverse events (TEAEs). As

bevacizumab is infused only once over 90 minutes (± 5 min) in treatment-relevant dose, the 
overall risk of the study for healthy subjects is considered to be acceptable.

OVERALL DESIGN AND PLAN OF THE STUDY 
3.1 
Overview 
This study is a double-blind, three-arm, parallel group, single-dose study. A total of 141 healthy 
male subjects aged between 19 and 55 years will be enrolled; 47 subjects in each of the 3 arms 
of the clinical study. In each arm, all subjects will receive a single dose of CT-P16, EU-
approved Avastin, or US-licensed Avastin by IV infusion for 90 min (±5 min) on Day 1 
followed by 15 weeks during which the PK, safety and immunogenicity measurements will be 
made. 
Subjects will be screened for eligibility within 21 to 2 days before the infusion of the IMP after 
they have signed an informed consent. Multiple visits may be needed during the screening 
period to complete study-related assessments. 
Eligible subjects will be admitted to the clinical unit on Day –1 to undergo baseline assessments 
and will be randomized on Day –1 to receive one of CT-P16, EU-approved Avastin, or US-
licensed Avastin once all eligibility criteria have been confirmed. Subjects will be confined to 
the clinical unit until completion of the 24-hour assessments after IMP administration. The 
consecutive study visits will be carried out on an out-patient basis. Blood for PK analysis will 
be collected up to Day 99. Safety will be assessed throughout the study by collection of 
information about AEs and concomitant medication, by clinical laboratory testing,

Investigator. 
4.4 
Subject Withdrawal and Replacement 
Subjects will be withdrawn 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. If the withdrawal occurs following IMP dosing, the subject will be asked to 
attend the clinical unit for safety assessments at the EOS examination. 

CELLTRION, Inc. 
CT-P16 1.1 
Clinical Study Protocol 
CONFIDENTIAL 
 
Version 1.0 
Page 28 of 65 
07 June 2017 
 
• Protocol violation of concern: The subject will be withdrawn by the Investigator after 
discussion with the Sponsor: 
−  If protocol violations or intercurrent illnesses 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 a subject reports symptoms that are considered unacceptable by the 
Investigator and/or Sponsor, he will be withdrawn from the study, e.g. abnormal laboratory 
values such as alkaline phosphatase (ALP), alanine aminotransferase (ALT) and aspartate 
aminotransferase (AST) elevated >5 times of upper limit of normal (ULN) laboratory range 
or uric acid >10 mg/dL or > 0.59 mmol/L with physiological consequences (according to 
Grade 4, CTCAE Version 4.03). 
The appropriate AE page in electronic case report form (eCRF) is to be completed. If premature 
withdrawal occurs for any reason, the Investigator must determine the primary reason for a 
subject's premature withdrawal from the study and record this information in the eCRF. 
Subjects who discontinue the study will be asked to participate in the safety assessments of the 
EOS procedures including a physical examination, vital sign measurements, 12-lead ECG and 
standard safety laboratory tests, if possible. 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 eCRF. 
Subjects will be allowed to rescreen only once, however, subjects withdrawn (after 
randomization) will not be replaced. 
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 should 
show due diligence by documenting in the source documents steps taken to contact the subject, 
e.g. dates of telephone calls, registered letters, etc. 
4.5 
Premature Termination of the Clinical Trial 
If the Investigator, the Sponsor, or the Medical Monitor becomes aware of conditions or events 
that suggest a possible hazard to subjects if the clinical study continues, then the clinical study 
may be terminated after appropriate consultation among the involved parties. The clinical study 
may be terminated at the Sponsor’s discretion also in the absence of such a finding. 
Conditions that may warrant termination of the clinical study include, but are not limited to: 
• The discovery of an unexpected, relevant, or unacceptable risk to the subjects enrolled in 
the clinical study (including but not limited to AEs, laboratory and/or vital sign

abnormalities that in the opinion of the Investigator/Sponsor are unacceptable for a further 
conduct of the study); 
• Failure to enroll subjects at the required rate; 
• A decision of the Sponsor to suspend or discontinue development of the IMP. 
Should the study be terminated and/or the site closed for whatever reason, Study related 
documents should be archived at the site according to the section 9.6. Used/unused IMP should 
be managed according to section 5.4. Any actions of the Investigator required for assessing or 
maintaining study subject safety will continue as required, despite termination of the study by 
the Sponsor.  
If the study is terminated for whatever reason, all subjects will be kept fully informed.

All IMP supplies must be stored in accordance with the manufacturer’s instructions and will 
be stored in a refrigerator at 2°C to 8°C and the vials will be protected from light. Until 
dispensed to the subjects, the IMPs will be stored in a securely locked area, accessible to 
authorized personnel only. 
5.4 
Drug Accountability, Dispensing and Destruction 
It is the responsibility of the clinical Investigator to ensure that all study drug received at the 
study center will be inventoried and accounted for throughout the study and the result recorded 
in the drug accountability form maintained at the study center. The drug accountability will be 
verified by the monitor during on-site monitoring visits.  
The Investigator agrees not to supply the study drug to any person other than sub-Investigator, 
designated staff, and the subjects participating in the study. Study drug may not be relabeled 
or reassigned for use by other subjects unless approved by CELLTRION, Inc. 
During the study, study drugs may need to be returned to the depot of origin. Unused study 
drug vials should be returned to the depot of origin. Accountability of the product must be 
completed at the site level and discrepancies, if any, need to be resolved prior to return. Only 
if it is written in standard operating procedures (SOPs) or documentation in place, the used 
vials can be destroyed locally. The list of destroyed vials must be recorded. The Investigator 
agrees to neither dispense the study drug from, nor store it at, any study center other than the 
study centers agreed upon with CELLTRION, Inc.  
Details in study drugs accountability and destruction will be followed according to the 
pharmacy manual. 
5.5 
Method of Assigning Subjects to Treatment Group 
5.5.1 
Screening numbers 
All screened subjects are assigned unique screening or run-in numbers. These numbers will be 
used to identify subjects during study period. 
5.5.2 
Randomization 
Randomization will occur at Day -1 after all baseline assessments have been performed and 
eligibility for the study has been confirmed. Subjects will be randomly assigned to treatment 
groups (1:1:1 ratio to CT-P16, EU-approved Avastin, or US-licensed Avastin) using the 
Interactive Web Response System (IWRS). The randomization will be balanced by using 
permuted blocks and will be stratified by body weight (<70 kg vs ≥70 kg) and site.

5.6 
Administration of Investigational Medicinal Products 
On Day 1, a subject will receive an IV infusion of CT-P16, EU-approved Avastin, or US-
licensed Avastin over 90 minutes (± 5 min) with an infusion pump. The infusion will take 
place starting in the morning under consideration of dietary and fluid restrictions (see 
Section 7.3.1). 
Subject will be residing in a semi-recumbent position while they receive the infusion of the 
IMP. By exception, the subject may get up (e.g., toilet visit) but he has to be instructed to call 
the study staff for assistance. Appropriate medical measures must be directly available in case 
of IRRs. The infusion must be interrupted if the intensity of the IRRs does not justify the 
continuation of the administration and would impose the subject to an unbearable risk as 
deemed by the Investigator or if a situation arises where the stopping rules apply (see Sections 
4.4 and 4.5). 
The infusion of CT-P16, EU-approved Avastin or US-licensed Avastin can be stopped 
immediately in the case of safety issues occurring during the infusion period at the 
Investigator’s discretion. An interruption of the infusion is permitted if the Investigator deems 
this appropriate (e.g., in case of signs dyspnea or clinically significant hypertension). The 
infusion will be resumed as soon as the cause of the interruption is resolved. If feasible, subjects 
will be followed for the safety and PK assessments given by the study design after they have 
received the infusion. 
5.7 
Compliance 
The infusion will be performed by trained, qualified personnel designated by the Investigator. 
The date and time of start of infusion (SOI) and end of infusion (EOI) will be documented. 
Comments will be recorded if there are any deviations from the planned dosing procedures. 
5.8 
Blinding and Breaking the Blind 
The study will be performed in a double-blind manner. All IMPs will be diluted by a designated 
unblinded pharmacist, and will be supplied to the treating physician or designee in a blinded 
manner, in identical infusion bags, thereby enabling double-blind conditions. 
The study blind should not be broken except in a medical emergency (where knowledge of the 
IMP administered would affect the treatment of the emergency) or regulatory requirement (e.g., 
for serious adverse events [SAEs] or death). 
The decision to break the blind will be made on a case-by-case basis, at the discretion of the 
Investigator/Sponsor. If the blind is broken, the date, time and reason must be recorded in the 
eCRF, and any associated AE report.

Version 1.0 
Page 33 of 65

If an emergency unblinding becomes necessary, the Investigator should notify the 
Sponsor/Medical Monitor prior to unblinding, if possible, unless identification of the IMP is 
required for emergency therapeutic measures. If the Investigator is unable to contact the 
Sponsor/Medical Monitor, the Investigator may, in an emergency, determine the identity of the 
treatment by using the applicable procedure in the IWRS.  
If a subject is unblinded, the subject must be withdrawn from the clinical study and procedures 
accompanying withdrawal are to be performed. 
Suspected unexpected serious adverse reactions (SUSARs), which are subject to expedited 
reporting, should be unblinded before submission to the Competent Authorities. 
The overall randomization code will be broken only for reporting purposes once all final 
clinical data have been entered into the database and all data queries have been resolved, and 
the assignment of subjects to the analysis sets has been completed. The randomization code 
will not be revealed to study subjects, parents or guardians, study site staff, or Investigators. 
5.9 
Concomitant Medications 
Any medicinal product, prescribed or over-the-counter (OTC) drug, including herbal and other 
non-traditional remedies, is considered a concomitant medication. Prior and concomitant 
medication use will be recorded for the 30 days prior to the screening visit until the EOS visit. 
Concomitant medication use is permitted if indicated by the Investigator for premedication or 
treatment of an AE. 
Subjects who had an exposure to a monoclonal antibody or currently used a biologic (including 
but not limited to anti-VEGF antibody) within 3 months prior to the administration of the IMP 
must be excluded. The use of OTC medications (including vitamins), or prescription 
medications within 7 days or 5 half-lives (whichever is longer) prior to the dose of the IMP 
until EOS will not be permitted. For live or attenuated vaccines, the vaccination within 30 days 
prior to the dose of the IMP until EOS will not be permitted. Herbal supplements must be 
discontinued 28 days prior to the administration of the IMP until EOS. Refer to Section 4.3 for 
exclusion criteria on concomitant medications and timing. 
5.10 Treatment of Overdose 
An overdose is defined as 10% or more than the dose prescribed. Overdose may be 
symptomatic or asymptomatic. Sign and Symptoms associated with an overdose must be 
recorded as an AE and recorded as detailed in Section 6.2.2.2, and an overdose without signs 
or symptoms must be documented in the IMP section in the eCRF. 
Although not strictly due to an overdose, IRR are possible and hypersensitivity must be 
monitored according to the details in Section 6.2.3.

6.2.2 
Adverse Events 
All AEs will be collected from the date the informed consent form (ICF) is signed and AE 
reporting will continue until the end of the subject's participation in the study. 
6.2.2.1 
Definitions 
An AE is any untoward medical occurrence in a subject or clinical investigation subject 
administered a pharmaceutical product and which does not necessarily have to have a causal 
relationship with this product. An AE can therefore be any unfavorable and unintended sign 
(including an abnormal laboratory finding, for example), symptom, or disease temporally 
associated with the use of a medicinal product, whether or not considered related to the 
medicinal product. 
All AEs, including intercurrent illnesses, occurring during the clinical study will be 
documented in the eCRF. Concomitant illnesses, which existed prior to signing the ICF, will 
not be considered AEs unless they worsen during the study period. Pre-existing conditions will 
be recorded in the eCRF on the Medical History or appropriate page. 
A TEAE is defined as an AE that begins or that worsens in severity after administration of the 
IMP. If laboratory test abnormalities occur after IMP infusion, only the clinically significant 
cases should be considered TEAEs. The clinically significant cases are ones that: 
• 
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)

• 
Require dose modification or dose delay 
• 
Are associated with clinical signs or symptoms judged by the Investigator to have a 
clinically significant impact 
Medical intervention such as surgery, diagnostic procedures, and therapeutic procedures are 
not AEs. The event term of primary cause should be recorded and reported instead of the term 
of surgery, diagnostic procedure, or therapeutic procedure. 
6.2.2.2 
Recording of Adverse Events 
Adverse events may be volunteered spontaneously by the study subject or discovered by the 
study staff during physical examinations or by asking an open, non-leading question such as 
“How have you been feeling since you were last asked?” All AEs and any required remedial 
action will be recorded. The nature of AE, date (and time, if known) of AE onset, date (and 
time, if known) and status of AE outcome, severity, and action taken of the AE will be 
documented together with the Investigator’s assessment of the seriousness of the AE and causal 
relationship to the IMP. 
All AEs should be recorded individually in the study subject’s own words (verbatim) unless, 
in the opinion of the Investigator, the AEs constitute components of a recognized condition, 
disease or syndrome. In the latter case, the condition, disease or syndrome should be named 
rather than each individual symptom. The AEs will subsequently be coded using the Medical 
Dictionary for Regulatory Activities (MedDRA). 
6.2.2.3 
Assessment of Adverse Events 
Terminology and severity grading of AEs will be recorded based on CTCAE Version 4.03. 
MedDRA version 20.0 or later will be recorded in statistical analysis plan (SAP) and used for 
reporting purpose (i.e. clinical study report and regulatory requirement). 
Each AE will be assessed by the Investigator with regard to the categories discussed in the 
sections below. 
6.2.2.3.1 
Intensity 
Investigator will assess all AEs for severity in accordance with the following criteria:

Grade 3: 
Severe or medically significant but not immediately life-threatening; 
hospitalization or prolongation of hospitalization indicated; disabling; limiting 
self-care ADL**. 
Grade 4: 
Life-threatening consequences; urgent intervention indicated. 
Grade 5: 
Death related to AE.

Note: a semicolon indicates “or” within each description. 
*Instrumental ADL refer to preparing meals, shopping for groceries or clothes, using the telephone, managing 
money, etc. 
**Self-care ADL refer to bathing, dressing and undressing, feeding self, using the toilet, taking medications, 
and not bedridden. 
When changes in the intensity of an AE occur more frequently than once a day, the maximum 
intensity for the event should be noted for that day. Any change in severity of signs and 
symptoms over a number of days will be captured by recording the change of intensity of the 
respective AE, with the amended severity grade, and the date (and time, if known) of the change. 
In the case of any event requiring medical intervention occurring during the in-house stay, the 
Investigator will institute general supportive measures including, where necessary, respiratory 
assistance and cardiopulmonary resuscitation. 
6.2.2.3.2 
Causality 
The Investigator will assess the causality/relationship between the IMP and the AE and record 
that assessment results in the eCRF. 
The most likely cause of an AE will be indicated in the eCRF with details of the concomitant 
disease or medication or other cause. 
The causal relationship of the AE to IMP will be described using following classification: 
• Definite: 
− This relationship suggests that a definite causal relationship exists between drug 
administration and the AE, and other conditions do not appear to explain the event. 
• 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.

• Possible: 
− This relationship suggests that treatment with the IMP 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 IMP, but could also have 
been produced by other factors. 
• Unrelated: 
− This relationship suggests that there is no association between the IMP and the reported 
event. 
6.2.2.3.3 
Expectedness 
An unlisted or unexpected AE is defined as an event of which the nature or severity is not 
consistent with the applicable product information (e.g. Investigator’s brochure [IB]) for an 
unapproved investigational product or the label (e.g. prescribing information or SmPC) for an 
approved product. If the IB for CT-P16 is delayed, the SmPC or prescribing information will 
take precedence. 
6.2.2.3.4 
Seriousness 
An SAE is defined as any untoward medical occurrence that: 
• Results in death; 
• Is life-threatening; this means that the subject is at risk of death at the time of the event; it 
does not mean that the event hypothetically might have caused death if it were more severe; 
• Requires at least 24-hour hospitalization or prolongation of expected length of stay. 
Hospitalization for elective medical/surgical procedures, scheduled treatments, or routine 
check-ups are not serious adverse events by these criteria; 
• Results in persistent or significant incapacity or substantial disruption of the ability to 
conduct normal life functions; 
• Is a congenital anomaly or birth defect; 
• Is another important medical event (see below). 
Important medical events that do not result in death, are not life-threatening, or do not require 
hospitalization may be considered SAEs when, based on appropriate medical judgment, they 
may jeopardize the subject and may require medical or surgical intervention to prevent one of 
the outcomes listed above. Examples of such medical events include allergic bronchospasm 
requiring intensive treatment in an emergency room or in a physician’s office, blood dyscrasias 
or seizures that do not result in in-patient hospitalization, and the development of drug 
dependency or drug abuse.

A distinction should be drawn between SAEs and severe AEs. Severity is a measure of intensity 
whereas seriousness is defined by the criteria above. For example, a mild degree of 
gastrointestinal bleeding requiring an overnight hospitalization for monitoring purposes would 
be considered an SAE, but is not necessarily severe. Similarly, an AE that is severe in intensity 
is not necessarily an SAE. For example, alopecia may be assessed as severe in intensity but 
would not be considered an SAE. 
Medical and scientific judgment should be exercised in deciding if an AE is serious and if 
expedited reporting is appropriate. 
6.2.2.3.5 
Adverse Events of Special Interest 
An ‘adverse event of special interest’ is an AE or occurrence that is designated to be of special 
interest and must be reported to the Sponsor using the same reporting process as an AE. 
The following events are considered events of clinical interest for this study: 
• Infusion-related reaction/hypersensitivity 
All AEs related to infusion include but are not limited to the following: urticaria, hypotension 
or hypertension, angioedema, hypoxia, bronchospasm, pulmonary infiltrates, acute respiratory 
distress syndrome, myocardial infarction, ventricular fibrillation, cardiogenic shock, or 
anaphylactoid events. 
6.2.2.4 
Reporting of Serious Adverse Events 
The Investigator will review each SAE and evaluate the intensity and the causal relationship of 
the event to IMP. All SAEs will be recorded from signing of informed consent until the EOS 
visit. Serious AEs occurring after the EOS visit and coming to the attention of the Investigator 
must be reported only if there is (in the opinion of the Investigator) reasonable causal 
relationship with the IMP. 
The Investigator is responsible for data entry in the electronic data capture system within 24 
hours of awareness of an SAE. In the event that is not possible (e.g., system failure or access 
problems), the study center should complete an SAE report form and fax to clinical research 
organization (CRO) Pharmacovigilance team within 24 hours of awareness of the event. 
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

The Sponsor will request clarification of omitted or discrepant information from the initial 
notification. The Investigator or an authorized delegate is responsible for faxing the requested 
information to the Sponsor within 24 hours of the Sponsor’s request.  
Initial reports of SAEs must be followed later with detailed descriptions, including clear 
photocopies of other documents as necessary (e.g. hospital reports, consultant reports, autopsy 
reports etc.), with the study subject’s personal identifiers removed. All relevant information 
obtained by the Investigator through review of these documents will be recorded and faxed to 
the Sponsor within 24 hours of receipt of the information. If a new SAE Report Form is 
received, then the Investigator must sign and date the form. The Sponsor may also request 
additional information on the SAE, which the Investigator or an authorized delegate must fax 
to the Sponsor within 24 hours of the request. 
6.2.2.5 
Follow-up of Adverse Events 
All AEs experienced by a subject, irrespective of the suspected causality, will be monitored 
until the event has been resolved, until any abnormal laboratory values have returned to 
baseline or stabilized at a level acceptable to the Investigator and Sponsor/Medical Monitor, 
until there is a satisfactory explanation for the changes observed, or until the subject is lost to 
Follow-up. 
6.2.2.6 
Procedure for Notification of Serious Adverse Event and Suspected 
Unexpected Serious Adverse Reactions to Institutional Review Boards 
If required by applicable local regulations, the Investigator shall promptly notify the relevant 
Institutional Review Board (IRB) (in addition to the Sponsor) of any SAE (including follow-
up SAEs) and SUSARs that occurred at his/her site or brought to his/her attention by the 
Sponsor. The Investigator shall verify that the IRB acknowledges receipt of the information.

The Sponsor will provide annual safety reports to the competent authorities and ethics 
committees responsible for the clinical study. These updates will include information on 
SUSARs and other relevant safety findings. 
6.2.2.7 
Pregnancy 
Women will be excluded from this study (see Section 4.3). However, the following directives 
describe the procedures and measurements that are to be considered if women of childbearing 
potential become pregnant who are partners of male subjects participating in this study. 
- If a female partner of a male subject who has been exposed to the IMP becomes pregnant, the 
course and outcome of the pregnancy should be monitored and documented. The baby will be 
followed for 1 year after the birth, provided consent from the pregnant partner of the subject is 
obtained. 
- The Sponsor or its designee has a responsibility to monitor the outcome of all pregnancies 
reported during the clinical study. 
- Each pregnancy must be reported by the Investigator to the Sponsor on the initial pregnancy 
report form within 24 hours after becoming aware of the pregnancy. The Investigator must 
follow up and document the course and the outcome of all pregnancies even if the subject was 
withdrawn from the clinical study or if the clinical study has finished. 
- All outcomes of pregnancy must be reported by the Investigator to the Sponsor on the 
pregnancy outcome report form within 24 hours after he/she has gained knowledge of the 
normal delivery or elective abortion. 
- The site must complete the supplied pregnancy form (the partner of a male subject) and return 
it to CRO Pharmacovigilance team within 24 hours (see Section 6.2.2.4). 
6.2.3 
Hypersensitivity Assessment 
Hypersensitivity will be assessed by routine clinical monitoring including BP, HR, RR and BT 
measurement and 12-lead ECG and recorded in accordance with the Schedule of Assessment 
for Hypersensitivity Monitoring (Table 3). Emergency equipment such as adrenaline, 
antihistamines, and respiratory support including inhalational therapy, oxygen, and artificial 
ventilation must be available. Subjects who develop a life-threatening IRR must be withdrawn 
from study. 
6.2.4 
Clinical Laboratory Assessments 
The safety laboratory analyses of blood including hematology, coagulation, and clinical 
chemistry, as well as urine drug screen will be performed according to validated methods and 
procedures. Laboratory analyses will be performed by the local laboratories.

The following laboratory variables will be determined in accordance with the Schedule of 
Assessments (Table 4): 
• Hematology: The following hematology parameters were assessed: hemoglobin, 
hematocrit, red blood cell (RBC) count, white blood cell (WBC) count with differential, 
absolute neutrophil count (ANC), and platelets. 
• Clinical chemistry: The following clinical chemistry parameters were assessed: albumin, 
alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase 
(AST), blood urea nitrogen (BUN), calcium, chloride, total cholesterol, creatine 
phosphokinase (CPK), creatine kinase–myocardial band isoenzyme (CK-MB), creatinine, 
creatinine clearance (estimated by Modification of Diet in Renal Disease [MDRD]), C-
reactive protein (CRP), gamma-glutamyl 
transferase (GGT), 
glucose, lactate 
dehydrogenase (LDH), triglycerides, magnesium, phosphate, potassium, sodium, total 
bilirubin, direct bilirubin, total protein, uric acid, Troponin I. 
• Coagulation: Fibrinogen, international normalized ratio (INR), prothrombin time (PT), 
activated partial thromboplastin time (aPTT). 
• Urinalysis: Color, pH, specific gravity, ketones, protein, glucose, bilirubin, nitrite, 
urobilinogen, occult blood, and microscopic examination. 
• Urine drug, alcohol and nicotine: screen for drugs of abuse including the following: 
amphetamines, barbiturates, benzodiazepines, cocaine, opiates, and cannabinoids. The test 
for drugs of abuse will be performed during the Screening Period only. The history of Drug 
abuse, Alcohol and nicotine will be checked by medical history taking by the Investigator 
during the Screening Period and Day -1. 
Any value outside the normal range will be flagged for the attention of the Investigator or 
designee at the site. The Investigator or designee will indicate whether or not the value is of 
clinical significance. If the result of any test (or repeat test, if done) from the samples taken 
during the screening period is indicated as clinically significant, the study subject will NOT be 
allowed into the study without permission of the Sponsor/Medical Monitor. However, retest is 
permitted only once during screening period by the Investigator’s judgment. Additional testing 
during the study period may be done if medically indicated. If a clinically significant 
abnormality 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 until the test(s) has 
(have) normalized or stabilized. 
6.2.5 
Vital Signs 
Vital signs will be assessed at time points specified in the Schedule of Assessments (Table 4). 
The following vital signs will be measured:

cardiac insufficiency or QT prolongation, the subject will be referred to a cardiologist and the 
event will be recorded in the source documents and the eCRF. 
6.2.7 
Physical Examinations 
Physical examinations will be performed at time points specified in the Schedule of 
Assessments (Table 4). 
The physical examination includes an assessment of general appearance and a review of 
systems. Information about the physical examination 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. 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. 
6.3 
Immunogenicity Variables 
The potential immunogenicity of CT-P16, EU-approved Avastin and US-licensed Avastin will 
be assessed in samples collected at the time points specified in the Schedule of Assessments

Assessments by Visit 
7.2.1 
Screening Visit (Days –21 to –2) 
All screening assessments will be the same for subjects in all parts of the study (unless otherwise 
indicated). 
Potential subjects for the inclusion in the study will be asked to attend the screening visit fasting 
apart from water (duration of the fast approximately 4 hours). Written informed consent will be 
obtained from all subjects before any screening procedures are performed. Subjects will be fully 
informed of their responsibilities (in terms of attending the study visits, dietary and lifestyle 
restrictions) of all the procedures expected to be performed in the study, the possible risks and 
disadvantages of being dosed with bevacizumab and their rights while participating in the study. 
They will have the opportunity to ask questions and have time to consider participation. If the 
subject wishes to participate in the study, they will be asked to sign and date the ICF. 
The screening visit will take place within the 21 days prior to dosing (Day –21 to Day -2) unless 
otherwise approved by the Sponsor/Medical Monitor or Investigator. If more tests or assessments 
are required to check the subject's eligibility for study participation, a subject may be invited to 
additional visits within the screening period at the discretion of the Investigator. 
During the screening visit, the following evaluations will be performed: 
• Obtain written informed consent 
• Medical and medication history 
• Demographics: race, gender, age (years) 
• Review inclusion/exclusion criteria 
• Body height (cm), weight (kg), and BMI (kg/m²) 
• Physical examination  
• Serology (hepatitis B, hepatitis C, HIV testing, and venereal disease research laboratory 
[VDRL] testing) 
• Screen for drugs of abuse, the history of drugs of abuse, alcohol and nicotine 
• Twelve-lead ECG 
• Vital signs (BP, HR, BT, and RR) 
• Clinical laboratory tests (hematology, clinical chemistry, coagulation, and urinalysis)

• AEs, concomitant medications and restriction assessments 
If in the opinion of the Investigator, the subject has any clinically significant abnormality, he will 
be excluded from the study. 
7.2.2 
In-House Stay (Day –1 to Day 2) and Out-Patient Visits (Day 3 to Day 85) 
Subjects who successfully complete the screening visit will be domiciled in the study center as 
scheduled on Day –1. Inclusion and exclusion criteria will be reviewed to confirm subject 
eligibility on admission. Subjects will enter the study center for the in-patient stay on Day –1. If 
the subject is eligible, he will be randomized on Day –1.  
Meals will be served during the in-house stay. The in-house stay will provide an enhanced level 
of subject supervision and safety; it will also facilitate the maintenance of compliance and ensure 
that all study procedures are completed at the appropriate time intervals. The subjects can be 
discharged from the clinical unit on Day 2 after all study procedures have been completed. 
Assessments on Day 3 and 4 can be carried out either during the In-House Stay or on an out-patient 
basis according to the Investigator decision. Thereafter, all study-related procedures and 
assessments will take place on an out-patient basis. Refer to Table 4 for a presentation of the single 
study procedures. 
7.2.3 
End-of-Study Visit (Day 99) 
On Day 99, subjects will return to the clinical unit for an EOS visit. The following evaluations will 
be performed: 
• Body weight 
• Physical examination 
• Clinical laboratory testing (hematology, clinical chemistry, coagulation and urinalysis)  
• Vital signs (BP, HR, BT, and RR) 
• Twelve-lead ECG 
• PK sampling 
• Sampling for immunogenicity against CT-P16, EU-approved Avastin and US-licensed Avastin 
• AEs, concomitant medications and restriction assessments

dealing with outliers will be defined in the SAP, prior to unblinding. 
8.3 
Safety Analyses 
8.3.1 
Adverse Events 
Adverse events will be graded for intensity and the terminology of AEs will be described according 
to the CTCAE v4.03. All safety data will be listed and summarized by treatment group as 
appropriate. Adverse events will be coded to system organ class and preferred term according to 
the Medical Dictionary for Regulatory Activities. 
The following TEAE summaries will be reported by system organ class, preferred term, and 
treatment group: 
• 
The number and percentage of subjects reporting at least 1 TEAE 
• 
The number and percentage of subjects reporting at least 1 TESAE 
• 
The number and percentage of subjects leading to permanent discontinuation due to an 
TEAE 
• 
The number and percentage of subjects with AESI  
If more than 1 TEAE is recorded for a subjects within any system organ class or preferred term, 
the subject will be counted only once within the respective summary. 
Adverse events will also be summarized by maximum intensity and relationship to IMP with the 
percentage of subjects in each category. 
Adverse events of special interest will also be summarized by intensity. 
8.3.2 
Clinical Laboratory Tests 
Clinical laboratory tests will be summarized by treatment group at each scheduled collection time. 
For continuous parameters, change from baseline will also be summarized for all post infusion 
scheduled collection times. All laboratory results will be listed.

8.3.6 
Immunogenicity analysis 
Immunogenicity will be summarized by treatment. 
8.4 
Pharmacokinetic Analyses 
The PK analysis will be conducted on the PK population. 
PK concentration data and parameters will be listed by subject including actual sampling times 
relative to dosing. Serum concentrations and parameters will be summarized by treatment. The 
following descriptive statistics will be presented for serum concentrations and parameters obtained 
at each nominal time point: n, mean, SD, coefficient of variation (CV), geometric mean, median, 
minimum and maximum values. 
The non-compartmental PK parameters listed in Sections 3.2.1 and 3.2.2 will be calculated using 
xxxxxxxxxxxxxxxxxx based on the following guidelines: 
• Cmax will be obtained directly from the concentration-time data. 
• Tmax is the time at which Cmax is observed. 
• λz will be estimated at terminal phase by linear regression after log-transformation of the 
concentrations: 
− Only those data points that are judged to describe the terminal log-linear decline will be 
used in the regression.

− A minimum number of 3 data points in the terminal phase will be used in calculating λz 
with the line of regression starting at any post-Cmax data point (Cmax will not be part of the 
regression slope) and including Clast and tlast. The adjusted coefficient of determination (R2 
adjusted) in general should be greater than 0.85. All the derived parameters (i.e. λz, t1/2, 
AUC0-inf, CL, and Vz) will need to be flagged accordingly. 
− An appropriate number of decimal places will be used for λz to enable the reported value 
of t1/2 to be calculated. 
• t1/2 will be calculated as ln2/λz. 
• AUC0-last and AUC0-inf will be calculated as follows: 
− The linear trapezoidal method will be employed for all incremental trapezoids arising from 
increasing concentrations and the logarithmic trapezoidal method will be used for those 
arising from decreasing concentrations.

• CL will be calculated as dose/AUC0-inf 
• Vz will be calculated as CL/λz 
• %AUCext will be calculated as (1 ￚ [AUC0-last/AUC0-inf]) × 100. The %AUCext should not 
exceed 20% for each individual profile. If the %AUCext is more than 20%, the individual result 
should be flagged as well as all parameters depending on AUC0-inf. All the derived parameters 
(i.e. AUC0-inf, Vd and CL) will need to be flagged accordingly. 
The statistical analysis of the log-transformed primary endpoints (AUC0-inf, AUC0-last, and Cmax) 
will be based on an analysis of covariance (ANCOVA) model. The difference in least squares 
means between the CT-P16 and EU-approved Avastin, CT-P16 and US-licensed Avastin, and EU-
approved Avastin and US-licensed Avastin, and the associated 90% CIs will be determined. Back 
transformation will provide the ratio of geometric means and 90% CIs for these ratios. 
Similarity of systemic exposure (AUC0-inf, AUC0-last, and Cmax) will be determined if 90% CI for 
the ratio of geometric means is within the acceptance interval of 80% to 125% for the following

Determination of Sample Size 
This study is powered to demonstrate PK equivalence of CT-P16, EU-approved Avastin and 
US-licensed Avastin in AUC0-inf, AUC0-last, and Cmax. Assuming a CV of 30% and ratio of 
geometric means of 1.03, 42 subjects for each arm are needed to achieve 90% power for a 90% CI 
for the ratio of AUC0-inf, AUC0-last, and Cmax to satisfy the equivalence margin of 80% to 125%. 
The sample size is calculated from two one-sided tests with each 5% significant level using 
geometric mean ratio. A 10% dropout rate is anticipated so approximately 141 subjects (47 in each 
arm) will be enrolled.

DATA COLLECTION AND QUALITY ASSURANCE 
9.1 
Data Quality Assurance 
The Sponsor or designee will conduct a study initiation visit to verify the qualifications of the 
investigator, inspect the facilities, and inform the Investigator of responsibilities and procedures 
for ensuring adequate and correct documentation. 
The Investigator must prepare and maintain adequate and accurate records of all observations and 
other data pertinent to the clinical study for each study participant. Frequent communication 
between the clinical site and the Sponsor is essential to ensure that the safety of the study is 
monitored adequately. The Investigator will make all appropriate safety assessments on an ongoing 
basis. All information recorded in the eCRF for this clinical study must be consistent with the 
subject’s source documentation. The Sponsor’s Medical Monitor may review safety information 
as it becomes available throughout the study. 
All aspects of the study will be carefully monitored with respect to Good Clinical Practice (GCP) 
for compliance with applicable government regulations (ICH 2016). The Study Monitor will be an 
authorized individual designated by the Sponsor. The Study Monitor will have access to all records 
necessary to ensure integrity of the data and will periodically review the progress of the study with 
the Investigator. 
9.2 
Data Collection 
Electronic Data Capture (EDC) will be used for this study, meaning that all eCRF data will be 
entered in electronic forms at the study site. Data collection will be completed by authorized study 
site staff designated by the Investigator. Appropriate training and security measures will be 
completed with the Investigator and all authorized study site staff prior to the study being initiated 
and any data being entered into the system for any study subjects. The Investigator will ensure that 
the data collected are accurate, complete and legible. 
The responsible study monitor will check data at the monitoring visits to the clinical study site. 
Data will be monitored within the eCRF by the study monitor before being exported. Any changes 
made during monitoring will be documented with a full audit trail within the eCRF. 
All clinical work conducted under this protocol is subject to GCP regulations.

9.3 
Case Report Forms and Source Documents 
All data obtained during the clinical study will be promptly recorded in the eCRF. All source 
documents from which eCRF entries are derived will be placed in the subject’s personal records. 
The original eCRF entries for each subject will be checked against source documents by the 
monitor. Instances of missing or uninterpretable data will be discussed with the Investigator for 
resolution. 
9.4 
Access to Source Documents 
During the course of the study, a monitor will make clinical study center visits to review protocol 
compliance, compare eCRF entries and individual subject’s personal records, assess IMP 
accountability and ensure that the clinical study is being conducted according to pertinent 
regulatory requirements. The eCRF entries will be verified against source documents. The review 
of medical records will be handled confidentially to ensure subject anonymity. 
Checking of the eCRF entries for completeness and clarity and verifying with source documents, 
will be required to monitor the clinical study for compliance with GCP and other regulations. 
Moreover, competent authorities of certain countries and IRBs may wish to carry out source data 
inspections on-site, and the Sponsor’s Clinical Quality Assurance Group may wish to carry out 
audits. Direct access to source data will be required for these inspections and audits; they will be 
carried out giving due consideration to data protection and subject confidentiality. The Investigator 
assures the Sponsor of the necessary support at all times. 
9.5 
Data Management 
Data management of all data documented will be performed under the responsibility of CRO or 
CELLTRION, Inc. 
A Clinical Data Management Plan (CDMP) will be provided to the Sponsor describing the work 
and data flow within this clinical study which will be using an EDC System. The EDC System will 
be customized for this study. Both the EDC System and CDMP will be sent to the Sponsor for 
review and approval. The CDMP must be finalized before database lock. 
For the EDC, a database structure that will host this study will be created and an interface to access 
it will be implemented. The system will establish and maintain the use of the computerized system 
according to the relevant SOP. Practical training sessions will be conducted on site to system users 
to teach them how to use the system.

Data will be collected individually in eCRFs. After all study materials are delivered and the eCRF 
is completed and validated, data will be entered in the clinical data storage system. Data will be 
available immediately to the data manager after it has been entered and therefore the data 
verification and validation process can start earlier contributing to data quality. 
Any missing, implausible, or inconsistent recordings will be referred back to the Investigator using 
a data query form and will be documented for each individual subject before clean file is declared. 
The AEs will subsequently be coded using the MedDRA, and prior and concomitant medications 
will be coded using the World Health Organization (WHO) Drug Dictionary. 
9.6 
Archiving Study Documents 
According to International Conference for Harmonization (ICH) guidelines, essential documents 
should be retained for a minimum of 2 years after the last approval of a marketing application in 
an ICH region and until there are no pending or contemplated marketing applications in an ICH 
region or at least 2 years have elapsed since the formal discontinuation of clinical development of 
the IMP. However, these documents should be retained for a longer period if required by the 
applicable legal requirements.

ETHICAL, LEGAL, AND ADMINISTRATIVE ASPECTS 
10.1 Good Clinical Practice 
The procedures set out in this clinical study protocol are designed to ensure that the Sponsor and 
the Investigator abide by the principles of the ICH guidelines on GCP and the Declaration of 
Helsinki (WMA 2013). The clinical study also will be carried out in keeping with national and 
local legal requirements. 
10.2 Informed Consent 
Before each subject is enrolled in the clinical study, written informed consent will be obtained 
from the subject according to the regulatory and legal requirements of the participating country 
and will be retained as part of the clinical study records. The Investigator will not undertake any 
investigation specifically required only for the clinical study until written consent has been 
obtained. The terms of the consent and when it was obtained must also be documented in the eCRF. 
The Investigator must ensure that the subject received full and adequate oral and written 
information about the nature, purpose, possible risk, and benefit of the study. Subjects must also 
be notified that they are free to withdraw from the study at any time without prejudice to future 
care. The subject should be given the opportunity to ask questions and allowed time to consider 
the information provided. 
If a protocol amendment is required, the ICF may need to be revised to reflect the changes to the 
protocol. If the ICF is revised, it must be reviewed and approved by the responsible IRB and signed 
by all subjects subsequently enrolled in the clinical study as well as those currently enrolled in the 
clinical study. 
10.3 Protocol Approval and Amendment(s) 
Before the start of the clinical study, the clinical study protocol and other relevant documents will 
be approved by the IRB, in accordance with local legal requirements. The Sponsor must ensure 
that all ethical and legal requirements have been met before the first subject is enrolled in the 
clinical study. 
This protocol is to be followed exactly. To alter the protocol, amendments must be written, which 
must be released by the responsible staff, and receive IRB approval prior to implementation (as 
appropriate).

Administrative changes may be made without the need for a formal amendment but will also be 
mentioned in the integrated clinical study report. All amendments will be distributed to all study 
protocol recipients, with appropriate instructions. 
10.4 Confidentiality Data Protection 
All clinical study findings and documents will be regarded as confidential. Study documents 
(protocols, IB, and other material) will be stored appropriately to ensure their confidentiality. The 
Investigator and members of his/her research team (including the IRB) must not disclose such 
information without prior written approval from the Sponsor, except to the extent necessary to 
obtain informed consent from subjects who wish to participate in the study or to comply with 
regulatory requirements. 
The anonymity of participating subjects must be maintained. Subjects will be specified on study 
documents by their subject number. Documents that identify the subject (e.g., the signed ICF) must 
be maintained in confidence by the Investigator. 
10.5 Liability and Insurance 
The Sponsor will take out reasonable third party liability insurance cover in accordance with all 
local legal requirements. The civil liability of the Investigator; the persons instructed by him/her 
and the hospital, practice, or institute in which they are employed; and the liability of the Sponsor 
with respect to financial loss due to personal injury and other damage that may arise as a result of 
the carrying out of this study are governed by the applicable laws and GCP guidelines. 
The Sponsor will arrange for subjects participating in this study to be insured against financial loss 
due to personal injury caused by the pharmaceutical products being tested or by medical steps 
taken in the course of the study. 
The method and manner of compensation to subjects should comply with applicable regulatory 
requirement(s). 
10.6 Publication Policy 
By signing the clinical study protocol, the Investigator agrees with the use of results of the clinical 
study for the purposes of national and international registration, publication and information for 
medical and pharmaceutical professionals. If necessary, the competent authorities will be notified
