test but negative chest X-ray). 
To implement FDA 
recommendation “Screening all 
subjects for TB at baseline. 
Subjects with a positive TB test 
should be evaluated for presence 
of active TB. Subjects with a 
baseline positive TB test but 
negative chest X-ray may be 
enrolled into the trial following 
initiation of appropriate treatment 
for latent tuberculosis.”

Overall Design: 
This is a randomized, double-blind, multicentric, parallel group, and active controlled study comparing 
efficacy, safety and immunogenicity of SC administration of DMB-3115 and EU sourced Stelara in patients 
with moderate to severe chronic plaque psoriasis. 
After a screening period of up to 4 weeks, the eligible patients will be randomly assigned in a 1:1 ratio to 
receive treatment with either DMB-3115 or Stelara. Randomization will be stratified according to patient’s 
body weight at baseline (≤100 kg or >100 kg), geographic region (EU, US or Rest of the World [ROW]) 
and the number of previous systemic therapies for psoriasis (<3 or ≥3). 
The study will have 2 periods. 
Period 1: 
In the Period 1 (from Week 0 to Week 28), patients will receive the assigned treatment (either DMB-3115 
or Stelara) at Weeks 0, 4, and 16. 
Patients who do not achieve at least Psoriasis Area and Severity Index (PASI) 50 response by Week 12 will 
be discontinued from further treatment with ustekinumab (either DMB-3115 or Stelara). 
Period 2: 
In the Period 2 (from Week 28 to Week 52), patients randomized to receive DMB-3115 at the beginning of 
the study will continue to receive the same treatment up to Week 40 while patients randomized to receive 
Stelara at the beginning of the study will be re-randomized and re-stratified based on the body weight at 
Week 28 (≤100 kg or >100 kg) at Week 28 in a 1:1 ratio to either continue on Stelara or will be transitioned 
to receive DMB-3115 every 12 weeks up to Week 40 (i.e., 2 doses of investigational product [IP] after re-
randomization). The doses at re-randomization (Week 28) for both DMB-3115 and Stelara would be 
re-assigned based on the body weight at Week 28 (≤100 kg or >100 kg). Patients receiving DMB-3115 will

continue to receive DMB-3115 up to Week 40 but they will also follow the re-randomization procedure in 
order to maintain blinding. Blinding will be maintained throughout the study. 
Only those patients who achieve at least PASI 75 response at Week 28 will be eligible for inclusion into 
the Period 2 of the study (Transition period: from Week 28 to Week 52). 
 
Patients who do not achieve at least PASI 50 response by Week 12 or PASI 75 response by Week 28 will 
be discontinued from further treatment with ustekinumab. These patients will remain in the study and be 
followed up to Week 52 for safety monitoring, including immunogenicity. For safety monitoring and 
immunogenicity in non-responders the following should be completed at follow-up visits: physical 
examination, vital signs, hematology and biochemistry laboratory tests, urine analysis, tuberculosis 
evaluation, anti-drug antibodies (ADA) blood sampling, electrocardiogram, pregnancy testing, and adverse 
events (AEs). All patients who discontinue treatment including non-responders as per Section 7.1 will 
remain in the study and be followed up to Week 52 for safety monitoring, including immunogenicity.  
Any patients who are prematurely withdrawn from the study at any time post IP administration at Visit 2, 
will be required to have an early termination (ET) visit. Early termination visit will be performed within 
12 weeks from the last IP administration. If ET visit occurs before 12 weeks, a phone call for safety 
follow-up will be performed at 12 weeks from the last IP administration.  
Efficacy, safety, and immunogenicity assessments will be done periodically.  
Blood samples for PK and ADA assessments will be collected prior to IP administration (in case a dose is 
scheduled for the same visit).  
Safety will be evaluated through an assessment of AEs, vital signs, electrocardiograms, and 
immunogenicity, along with clinical laboratory testing.  
The patients will visit the clinical site for screening and then at baseline (Week 0/Day 1), Week 0/Day 2, 
Week 1, Week 2, Week 4, and then every 4 weeks up to Week 16. Thereafter, the patients will visit the 
clinical site every 12 weeks up to Week 52. The last visit at Week 52 will be End of Study (EOS) visit. 
There are total 12 scheduled visits planned, including the screening and EOS visit. 
An Interim Analysis will be performed when all active patients complete the Week 28 assessment visit. 
The efficacy endpoints up to Week 28 and all available safety, ADA and PK data will be analyzed and an 
interim clinical study report will be generated for submission to the regulatory agencies. 
Number of Investigators and Study Sites: 
Approximately 124 Investigators and sites are expected to participate in this study. 
Number of Patients: 
Assuming a dropout rate of 20% in Period 1, 15% in Period 2, and considering the 1:1 re-randomization 
rate for Stelara arm in Period 2 and to meet the minimum requirement of safety analysis by European 
Medicines Agency (EMA) (N=100), 590 patients (a minimum of 400 completed patients) will be necessary 
in total.  
Thus, 590 patients (295 patients per treatment group at baseline) will be enrolled. 
Treatment Groups and Duration: 
Two treatment groups (DMB-3115, and Stelara) in Period 1 and 3 treatment groups (DMB-3115, Stelara, 
and Stelara switched to DMB-3115) for Period 2. 
Patients who weigh ≤100 kg will receive an initial dose of 45 mg ustekinumab administered subcutaneously 
(either DMB-3115 or Stelara as assigned), followed by another 45 mg dose 4 weeks later, and then every 
12 weeks thereafter (up to 40 weeks after randomization). Patients who weigh >100 kg will receive 90 mg 
doses as per same schedule. 
The doses at re-randomization (Week 28) would be assigned on the body weight at that time. 
The total duration of patient participation in the study will be up to 56 weeks.

Statistical methods: 
All data listings, summaries, and analyses will be performed under the guidance and approval of the 
Sponsor. 
Descriptive statistics will be used for all variables, as appropriate. Continuous variables will be summarized 
by the number of observations, mean, standard deviation (SD), median, minimum, and maximum. 
Categorical variables will be summarized by frequency counts and percentages for each category. Unless 
otherwise stated, percentages will be calculated out of the total population for each treatment group. 
Primary Efficacy Analysis (for European Medicines Agency [EMA]) 
• 
Percent change in PASI at Week 8 will be analyzed with a 95% confidence interval (CI) for the 
difference in means using estimates from an Analysis of Covariance (ANCOVA) model adjusted for 
baseline PASI score and the stratification factors (patient’s body weight at baseline [≤100 kg, or 
>100 kg], geographic region [EU, US or ROW] and the number of previous systemic therapies for 
psoriasis [<3 or ≥3]). 
• 
Equivalence between the 2 treatment groups will be declared if the 95% CI of the mean difference is 
entirely contained within the pre-specified equivalence margin of (-15%, 15%).  
• 
Analysis will be performed in the Intent-to-Treat (ITT) and Per Protocol Set (PPS). The PPS is the 
primary efficacy analysis population. 
• 
Missing values for primary efficacy variable in the ITT set will be imputed by multiple imputation 
(MI) method. 
Primary Efficacy Analysis (for United States Food and Drug Administration [US FDA]) 
• 
Percent change in PASI at Week 12 will be analyzed with a 90% CI for the difference in means using 
estimates from an ANCOVA model adjusted for baseline PASI score and the stratification factors 
(patient’s body weight at baseline [≤100 kg, or >100 kg], geographic region [EU, US, or ROW] and 
the number of previous systemic therapies for psoriasis [<3 or ≥3]). 
• 
Equivalence between the 2 treatment groups will be declared if the 90% CI of the mean difference is 
entirely contained within the pre-specified equivalence margin of (-10%, 10%).  
• 
Analysis will be performed in the ITT and PPS. The ITT is the primary efficacy analysis population. 
• 
Missing values for primary efficacy variable in ITT set will be imputed by MI method.  
Sensitivity Analysis 
Percent change in PASI will be analyzed for each PPS and ITT set (EMA and US FDA) using a mixed 
linear model with treatment group, baseline body weight (≤100 kg, or >100 kg), geographic region (EU, 
US or ROW), the number of previous systemic therapies for psoriasis (<3 or ≥3), visit, and the 
treatment-by-visit interaction as fixed effects and baseline PASI score as a covariate. The treatment mean 
difference at Week 8 (for EMA) and Week 12 (for US FDA), along with CI are calculated. The 
variance-covariance matrix of unstructured form is used to model the correlation within each patient. 
Secondary Efficacy Analysis 
Endpoints based on proportions will be analyzed using a logistic regression test with the baseline value, 
baseline body weight (≤100 kg, or >100 kg), geographic region (EU, US or ROW), and the number of 
previous systemic therapies for psoriasis (<3 or ≥3) as covariates. Percentage change from baseline will be 
analyzed using ANCOVA with baseline PASI score, body weight (≤100 kg, or >100 kg), geographic region 
(EU, US or ROW), and the number of previous systemic therapies for psoriasis (<3 or ≥3) as covariates. 
Change from baseline in Dermatology Life Quality Index (DLQI) will be analyzed using ANCOVA with 
baseline DLQI score, body weight (≤100 kg, or >100 kg), geographic region (EU, US or ROW), and the 
number of previous systemic therapies for psoriasis (<3 or ≥3) as covariates. All the secondary efficacy 
endpoints are summarized by the 90% CI (for US FDA) and 95% CI (for EMA). 
 


CONFIDENTIAL 
Protocol DMB-3115-2 - Protocol Amendment 01 
 
16 
Supportive Analysis to Secondary Endpoint for Period 2 
Percentage change in PASI score from baseline to Weeks 40 and 52 will be analyzed using ANCOVA with 
Welch’s test with baseline PASI score, body weight (≤100 kg, or >100 kg), geographic region (EU, US, or 
ROW), and the number of previous systemic therapies for psoriasis (<3 or ≥3) as covariates. 
Safety Analysis 
The number and proportion of patients experiencing AEs and Serious Adverse Events will be tabulated and 
compared by treatment group. Adverse events will be coded according to the Medical Dictionary for 
Regulatory Activities (MedDRA).  
Vital signs and clinical laboratory parameters being monitored for safety will be summarized by treatment 
and scheduled time point using descriptive statistics of number of observations, mean, SD, minimum, 
median, and maximum. Data listings of clinically significant abnormalities/outliers will be presented.  
Immunogenicity Analyses  
The incidence of ADAs and neutralizing antibodies will be summarized by treatment group and visit and 
listed.  
Pharmacokinetic Analysis 
Pharmacokinetic data will be summarized descriptively. Pharmacokinetic parameters after the first dose 
(e.g., Cmax, tmax, area under the concentration-time curve from Week 0 to Week 4 [AUCw0-w4] and other PK 
parameters, as appropriate) will be determined using an appropriate analysis methodology. 
Additional details about the statistical methods including, but not limited, analysis sets, missing data 
strategies, etc. will be provided in the body of the protocol and the Statistical Analysis Plan (SAP) which 
will be prepared as a separate document prior to database lock. 
Statistical Hypotheses 
Statistical hypotheses and testing utilized will be defined in the SAP, including the null and alternative 
hypotheses. Primary and secondary endpoint analyses will be included in the SAP. 
Sample Size Determination 
The sample size required for the primary endpoint has been calculated based on the following assumptions; 
two-sided alpha of 0.05 (for EMA) or 0.10 (for US FDA), power of 90%, the difference between Stelara 
and DMB-3115 is 0, and the SD is 0.3. One to one (1:1) randomization rate of Period 1 is assumed. 
Equivalence margins of 15% and 10% were recommended by the EMA and US FDA, respectively. The SD 
assumption was derived from the observed SD of the mean improvement in PASI score in studies 
PHOENIX 1 and PHOENIX 2. Sample size was calculated using the Two one-sided t-tests (TOST) 
procedure as implemented in the R package power TOST. The overall sample size will be based on the 
larger sample size calculated through EMA and US FDA’s recommendation.

As shown in above table, for primary efficacy analysis, the US FDA sample size of 490 patients in total 
(245 patients per treatment group at baseline) is selected to achieve 392 evaluable patients to have a 90% CI 
for the difference in primary endpoint fall entirely within the 10% equivalence margin with more than 
90% power.  
On the other hand, for safety analysis, a minimum of 400 completed patients (at least 100 patients per 
treatment group for long-term data) will be necessary to meet the minimum requirement by EMA 
considering 1:1 re-randomization for Stelara arm. To achieve 400 completed patients, 590 patients 
(295 patients per treatment group at baseline) need to be enrolled assuming both dropout rate of 20% in 
Period 1 and 15% in Period 2. 
The total number of patients needed for the safety analysis is larger than that needed for the primary efficacy 
analysis. Thus, 590 patients (295 patients per treatment group) in total need to be enrolled (randomized). 
Populations for Analyses 
For the purpose of analysis, the analysis sets are defined.  
• 
Intent-to-Treat set: All patients who have been randomized.  
• 
Per protocol set (for EMA): Patients who complete the study up to Week 8 and have no major protocol 
deviations. All decisions to exclude the patients from the per protocol population dataset will be made 
prior to the unblinding of the study.  
• 
Per protocol set (for US FDA): Patients who complete the study up to Week 12 and have no major 
protocol deviations. All decisions to exclude patients from the per protocol population dataset will be 
made prior to the unblinding of the study.  
• 
Safety set: Patients who randomize and receive at least 1 dose of the IP. The safety analysis will be 
conducted according to the treatment that a patient actually receives. 
• 
PK analysis set: Patients who receive at least 1 dose of IP, have at least one measured concentration at 
a scheduled post dose PK time point, and have no major protocol deviations/events that may 
significantly affect the PK assessment.  
 
Data Monitoring Committee:  
An independent Data Safety Monitoring Board (DSMB) will be constituted by the study Sponsor to oversee 
the safety aspects of this study. The DSMB will include physicians with relevant clinical expertise, none of

18 
whom is affiliated with the Sponsor. The DSMB will operate as per a written charter. The DSMB would 
periodically examine the safety data emerging from the study and provide its recommendations to the 
Sponsor. Based on its review, the DSMB may advise for the study to be continued as is, or for the protocol 
to be modified, or for the study to be terminated.

e. Laboratory blood tests: Hematology = hemoglobin, hemoglobin A1c, hematocrit, platelet count, Red Blood Cell (RBC) Count, white blood cell count (total and
differential), Mean corpuscular volume (MCV), Mean corpuscular hemoglobin (MCH), and erythrocytes sedimentation rate (ESR). ESR test will be done locally
with kits provided by central laboratory.
Biochemistry = sodium, potassium, creatinine, glucose (fasting status not mandatory), calcium, phosphorus, total bilirubin, direct bilirubin, albumin, alanine
aminotransferase, aspartate aminotransferase, alkaline phosphatase, blood urea nitrogen, total protein, and C-reactive protein.  
Other = Follicle stimulating hormone (as needed in women of non‑childbearing potential only at screening visit), prothrombin time, activated partial 
thromboplastin time, and international normalized ratio (see Section 8.2.6 and Appendix 3). 
f. Urinalysis: Color, Clarity/Appearance, protein, blood, leucocytes, nitrite, glucose, ketone, pH, specific gravity, bilirubin, urobilinogen, microscopic examination
(if blood or protein is abnormal).
g. Serum pregnancy test must be performed at screening visit for all females of childbearing potential only. Thereafter, from randomization onwards, a urine
pregnancy test will be performed at Weeks 0, 4, 16, 28, 40, and 52 and should be negative before each IP administration. Pregnancy testing will be performed
whenever a menstrual cycle is missed or when pregnancy is otherwise suspected (see Appendix 6).
h. 12-lead ECG will be performed as detailed in Section 8.2.3.
i. Blood samples for PK analysis will be collected at Weeks 0 (Pre dose and 24 hours post dose [±12 hours]), 1, 2, 4, 8, 12, 16, 28, 40, and 52. At visits when IP is
to be administered, the PK sample will be collected prior to IP administration.
j. Blood samples for ADA analysis will be collected at Weeks 0 (Pre dose and 24 hours post dose [±12 hours]), 2, 4, 8, 12, 16, 28, 40, and 52. At visits when IP is
to be administered, the ADA sample will be collected prior to IP administration.
k. At Week 28, patients who achieved a PASI 75 response will enter the study transition period. Patients receiving Stelara will be re-randomized in a 1:1 ratio to
either continue to receive Stelara or be transitioned to DMB-3115. Patients receiving DMB-3115 will continue to receive DMB-3115 up to Week 40 but they
will also follow the re-randomization procedure in order to maintain blinding.
l. Patients who do not achieve at least PASI 50 response by Week 12 will be discontinued from further treatment with ustekinumab. These patients will remain in
the study and will be followed up to Week 52 for safety monitoring, including immunogenicity.
m. Patients who do not achieve at least PASI 75 response by Week 28 will be discontinued from further treatment with ustekinumab (either DMB-3115 or Stelara).
These patients will remain in the study and will be followed up to Week 52 for safety monitoring, including immunogenicity.
n. Appropriate medical personnel must be in attendance at the time of the injection and for at least 30 minutes after the SC injection.
o. The PASI, PGA, and DLQI assessments shall be completed using the electronic devices provide by the site.
p. Previous and concomitant medication at screening and concomitant medication only at visits from randomization onwards (see Section 6.5).
q. Safety data reporting period begins from the time of signing the informed consent (even if this is prior to randomization visit) until Week 52 (±7 days). Note:
Related SAEs should be collected irrespective of the time elapsed since the last dose of IP. For detailed instructions on safety reporting (see Appendix 4).
r. Patients who are prematurely withdrawn from the study at any time post Visit 2, will be required to have an ET visit. The ET visit will be performed within
12 weeks from the last IP administration. If ET visit occurs before 12 weeks, a phone call for safety follow-up will be performed at 12 weeks from the last IP
administration.

1. INTRODUCTION 
This document describes the rules and conventions to be used in the presentation and analysis of safety, immunogenicity, 
pharmacokinetic (PK) data and efficacy data.  
Current SAP has been generated based on Protocol No (DMB-3115-2)-Amedment-01 dated 04JUN 2021. 
2. STUDY OBJECTIVES 
2.1. PRIMARY OBJECTIVE 
• 
To evaluate efficacy of DMB-3115 in comparison with Stelara sourced from the EU. 
2.2. SECONDARY OBJECTIVES 
• 
To evaluate safety, tolerability, PK, and immunogenicity of DMB-3115 in comparison with Stelara sourced from the EU. 
2.3. EXPLORATORY OBJECTIVES 
• 
Not Applicable. 
3. STUDY DESIGN 
3.1. GENERAL DESCRIPTION 
This is a randomized, double-blind, multicentric, parallel group, and active controlled study comparing efficacy, safety and 
immunogenicity of subcutaneous administration of DMB-3115 and EU sourced Stelara in patients with moderate to severe chronic 
plaque psoriasis.  
The study includes a screening period of up to 4 weeks followed by IP administration of up to Week 40 and last (EOS) assessment at 
Week 52. 
After a screening period of up to 4 weeks, the eligible patients will be randomly assigned in a 1:1 ratio to receive treatment with either 
DMB-3115 or Stelara. Randomization will be stratified according to patient’s body weight at baseline (≤100 kg or >100 kg), geographic 
region (EU, US or Rest of the World [ROW]) and the number of previous systemic therapies for psoriasis (<3 or ≥3).

The study will have 2 periods: 
 
Period 1: In the Period 1 (from Week 0 to Week 28), patients will receive the assigned treatment (either DMB-3115 or Stelara) at Weeks 
0, 4, and 16.  
Patients who do not achieve at least Psoriasis Area and Severity Index (PASI) 50 response by Week 12 will be discontinued from further 
treatment with ustekinumab (either DMB-3115 or Stelara). 
Period 2: In the Period 2 (from Week 28 to Week 52), patients randomized to receive DMB-3115 at the beginning of the study will 
continue to receive the same treatment up to Week 40 while patients randomized to receive Stelara at the beginning of the study will be 
re-randomized at Week 28 in a 1:1 ratio to either continue on Stelara or will be transitioned to receive DMB-3115 every 12 weeks up to 
Week 40 (i.e., 2 doses of investigational product [IP] after re-randomization).   
The Doses at re-randomization (Week 28) for both DMB-3115 and Stelara would be reassigned based on body weight at Week 28 (≤100 
kg or >100 kg). Patients receiving DMB-3115 will continue to receive DMB-3115 up to Week 40 but they will also follow the re-
randomization procedure to ensure blinding. Blinding will be maintained throughout the study.  
 
Only those patients who achieve at least Psoriasis Area and Severity Index (PASI) 75 response at Week 28 will be eligible for inclusion 
into the Period 2 of the study (Transition period: from Week 28 to Week 52).  
Patients who do not achieve at least PASI 50 response by Week 12 or PASI 75 response by Week 28 will be discontinued from further 
treatment with Ustekinumab. These patients will remain in the study and be followed up to Week 52 for safety monitoring, including 
immunogenicity. For safety monitoring and immunogenicity in non-responders the following should be completed at follow-up visits: 
physical examination, vital signs, hematology and biochemistry laboratory tests, urine analysis, tuberculosis evaluation, anti-drug 
antibodies (ADA) blood sampling, electrocardiogram, pregnancy testing, and adverse events (AEs). All patients who discontinue 
treatment including non-responders will remain in the study and be followed up to Week 52 for safety monitoring, including 
immunogenicity. 
Safety will be evaluated through an assessment of AEs, vital signs, electrocardiograms, and immunogenicity, along with clinical 
laboratory testing. 
Number of Investigators and Study Sites: 
Approximately 124 Investigators and sites are expected to participate in this study.  
Number of Patients:  
For primary efficacy analysis, the US FDA sample size of 490 patients in total, or 245 patients per treatment group at baseline, is selected

to achieve 392 evaluable patients to have a 90% CI for the difference in primary endpoint fall entirely within the 10% equivalence 
margin with more than 90% power. 
Assuming a dropout rate of 20% in Period 1, 15% in Period 2, and considering the 1:1 re-randomization rate for Stelara arm in Period 
2 and to meet the minimum requirement of safety analysis by EMA (N=100), 590 patients (a minimum of 400 completed patients) will 
be necessary in total.  
Thus, 590 patients (295 patients per treatment group) will be enrolled.  
Treatment Groups and Duration:  
Two treatment groups (DMB-3115, and Stelara) in Period 1 and 3 treatment groups (DMB-3115, Stelara, and Stelara switched to DMB-
3115) for Period 2. Patients who weigh ≤100 kg will receive an initial dose of 45 mg ustekinumab administered subcutaneously (either 
DMB-3115 or Stelara as assigned), followed by another 45 mg dose 4 weeks later, and then every 12 weeks thereafter (up to 40 weeks 
after randomization). Patients who weigh >100 kg will receive 90 mg doses as per same schedule. The doses at re-randomization (Week 
28) would be assigned on the body weight at that time. The total duration of patient participation in the study will be up to 56 weeks.

3.3. CHANGES TO ANALYSIS FROM PROTOCOL 
There will be additional sensitivity analysis conducted for COVID-19 affected subjects for which protocol will not be updated. COVID-
19 analysis: As the pandemic started at the time of recruitment and as per regulatory requirement sensitivity analysis e.g. extended 
window, is planned for COVID-19 patients, if any. 
Definition of Per Protocol set (EMA and USFDA) has been modified to indicate impact on primary efficacy analysis. Additional reasons 
which may impact primary endpoint has been added. Modifications for the same can be found in section 5.3 and 5.4.  
Subgroup analyses of treatment group differences for assessing Percent change in PASI will be presented for the primary endpoint 
based on imputed data. 
 
4. PLANNED ANALYSIS  
4.1. INTERIM ANALYSIS 
An interim analysis will be performed when all active patients complete the Week 28 assessment visit. The efficacy endpoints up to 
week 28 and all available safety, ADA and PK data will be analyzed using the analysis methods described in this plan and an interim 
clinical study report will be generated for submission to the regulatory agencies. A limited number of identified individuals of the 
Sponsor or CRO will be unblinded for the interim analysis. However, patients, Investigators, and other study personnel will remain 
blinded throughout the entire study period. 
4.2. FINAL ANALYSIS 
Final analysis will be performed when all active patients complete the Week 52 assessment visit. The efficacy endpoints up to week 52 
and all available safety, ADA and PK data will be analyzed using the methods described in the analysis plan and a final CSR report will 
be generated for submission to the regulatory agencies. 
5. ANALYSIS SETS 
Agreement and authorization of subjects included/excluded from each analysis set will be conducted prior to the unblinding of the study.

Percentage of subjects in each category, SD: N + 2 
p-values will be presented with 4 decimal places 
See Section 20 for descriptive statistics of PK data. 
 
6.1. REFERENCE START DATE AND STUDY DAY 
Study Day will be calculated from the reference start date and will be used to show start/stop day of assessments and events.  
Reference start date is defined as the day of the first dose of study medication, (Day 1 is the day of the first dose of study medication) 
and will appear in every listing where an assessment date or event date appears. 
If the date of the event is on or after the reference start date, then:  
Study Day = (date of event – reference start date) + 1. 
If the date of the event is prior to the reference start date, then:  
Study Day = (date of event – reference start date). 
In the situation where the event date is partial or missing, study day, and any corresponding durations will appear partial or 
missing in the listings.  
6.2. BASELINE 
Unless otherwise specified, baseline is defined as the last non-missing measurement taken prior to reference start date (including 
unscheduled assessments). In the case where the last non-missing measurement and the reference start date/time coincide, that 
measurement will be considered pre-baseline, but Adverse Events (AEs) and medications commencing on the reference start date will 
be considered post-baseline. 
6.3. RETESTS, UNSCHEDULED VISITS AND EARLY TERMINATION DATA 
In general, for by-visit summaries, data recorded at the nominal visit will be presented. Unscheduled measurements will not be included 
in by-visit summaries.

In the case of a retest (same visit number assigned), the latest available measurement for that visit will be used for by-visit summaries.  
Early termination data will be mapped to the ET/End of Study Follow-Up visit for by-visit summaries. 
Listings will include scheduled, unscheduled, retest and early discontinuation data. 
6.4. STATISTICAL TESTS 
Primary efficacy endpoint will be analyzed using an Analysis of Covariance (ANCOVA) at Week 8 (for EMA) and Week 12 (for US 
FDA). 
Secondary efficacy endpoints will be analyzed using ANCOVA and logistic regression for protocol specified visits and supportive 
analysis to secondary efficacy endpoint for Period 2 will be performed using ANCOVA with Welch’s test. 
Primary and secondary efficacy endpoints will be analyzed with 95% CI (for EMA) and 90% CI (for US FDA). using ANCOVA and 
Logistic Regression. Confidence Interval, Standard Errors and P values will be provided based on ANCOVA Model Results. 
Sensitivity and supportive analyses will be analyzed with 95% CI (for EMA) and 90% CI (for US FDA). 
Subgroup analyses of treatment group differences for assessing Percent change in PASI will be analyzed using an ANCOVA for the 
primary endpoint at Week 8 (for EMA) and Week 12 (for US FDA). 
 
6.5. COMMON CALCULATIONS 
Unless otherwise specified, for quantitative measurements, change from baseline will be calculated as: 
Test Value at Visit X – Baseline Value  
6.6. SOFTWARE VERSION 
Non-compartmental PK parameter calculations will be performed using Phoenix® WinNonlin® Version 8.3 or higher (Certara L.P., 
Princeton, New Jersey, USA.  All other analyses will be conducted using SAS® software (version 9.4 or higher).

See Appendix 2 for handling of partial dates for medications, in the case where it is not possible to define a medication as prior, or 
concomitant, the medication will be classified by the worst case; i.e. concomitant.  
14. STUDY MEDICATION EXPOSURE 
Treatment groups in study listed as below: 
Two treatment groups (DMB-3115, and Stelara) in Period 1 and 3 treatment groups (DMB-3115, Stelara,  
and Stelara switched to DMB-3115) for Period 2. 
Exposure to study medication will be summarized by body weight (≤100kg and >100kg) for duration exposure, average dose 
at week and cumulative average dose (mg) for all weeks for the SAF. A listing will also be provided. 
Duration of medication exposure (weeks)= (Date of last study medication administration – Date of first study medication 
administration+1)/7. 
Duration of exposure (days)=Date of last dose of study drug -Date of first dose of study drug +1. 
 
15. STUDY MEDICATION COMPLIANCE  
• 
Compliance with trial medication will be based on the eCRF page “IP Administration”. An administered injection is 
considered when the question “Was Dose administered?” is answered “Yes”. Study medication compliance will be based 
on SAF. 
• 
Compliance will be based on the comparison of actual administered injections and the planned usage. 
  
Compliance will include visits until treatment discontinuation. 
• 
‘Per visit’ compliance will be calculated as: 
Compliance at visit N = Yes if the question “Was Dose administered?” is answered “Yes”.

17. EFFICACY OUTCOMES  
17.1. 
PRIMARY EFFICACY 
To evaluate efficacy of DMB-3115 in comparison with Stelara sourced from the EU. 
17.1.1. 
PRIMARY EFFICACY VARIABLE(S)  
The primary efficacy variable is 
• 
Percent change in the Psoriasis Area and Severity Index (PASI) score from baseline to Week 8 (For EMA). 
• 
Percent change in the PASI score from baseline to Week 12 (For US FDA). 
17.1.2. 
MISSING DATA METHODS FOR PRIMARY EFFICACY VARIABLE(S) 
Missing efficacy data for the primary endpoint will be handled using a Multiple Imputation (MI) procedure as follows: 
Step 1- Creation of monotone missing data structure using 50 interactions (M), to ensure that the results do not suffer from a relative 
efficiency loss. 
Intermediate (non-monotone) missing data (where some subjects may have missing records) will be imputed using the Markov Chain 
Monte Carlo (MCMC) method including treatment arm, PASI_Baseline, PASI_Week4, PASI_Week8, PASI_Week12, and assuming 
that the joint distribution of these variables is multivariate normal and the pattern for missing data is arbitrary. For this step the SAS 
procedure PROC MI with the MCMC option will be used 
Step 2- Further imputations:  
The datasets, now with monotone missing data, will be imputed further, in a stepwise manner to impute each week’s PASI from Week 
1 to Week 12 using the regression method (assuming missing at random). The model for each week will include terms for all the previous 
weeks and follow the structure of the following model for each visit. 
17.1.3. 
PRIMARY ANALYSIS OF PRIMARY EFFICACY VARIABLE(S) 
The primary objective of this study is to test the hypothesis that 
H0:  |Treatment(DMB-3115) – Treatment(Stelara)| ≥ 𝛿

Whereas 𝛿 is an equivalence margin which is defined as for EMA regulatory submission as [-15%, 15%] and for US FDA consider as 
[-10%, 10%]. 
The primary efficacy analysis will be performed for the PPS and the ITT analysis set for both regulatory submission (EMA at 8 week 
and US FDA at 12 week). 
Primary Efficacy Analysis (for EMA)  
• 
Percent change in PASI at Week 8 will be analyzed with a 95% CI for the difference in means using estimates from an 
ANCOVA model adjusted for baseline PASI score and the stratification factors (patient’s body weight at baseline (≤100 kg 
or >100 kg), geographic region (EU, US or ROW) and the number of previous systemic therapies for psoriasis (<3 or ≥3)). 
• 
Equivalence between the 2 treatment groups will be declared if the 95% CI of the mean difference is entirely contained within 
the pre-specified equivalence margin of (-15%, 15%). 
• 
Analysis will be performed in the ITT and PPS. The PPS is the primary efficacy analysis population. 
• 
Missing values for primary efficacy variable in the ITT will be imputed by MI method.

Percentage change from baseline will be calculated at each timepoint based on PASI score and then below mentioned trapezoidal formula 
will be applied for AUEC calculation 
 AUEC=∑i=2 1/2 (Mi-1+Mi)*(ti-ti-1); where i=2, …, k, t1=0, and M1=0 
Each Trapezoidal value is added cumulatively and last observation at a given timepoint will be its AUEC value 
Percent change of PASI value (%) at visit x =  (PASI value at baseline – PASI score at visit X)/ PASI value at baseline x 100 
Where m is the percent change of PASI Score and t is the timepoints for PASI Score. As per the above formula (trapezoidal rule) 
calculate the trapezoidal values for each timepoint.

17.2.3. 
SENSITIVITY ANALYSIS OF PRIMARY EFFICACY VARIABLES 
Percent change in PASI will be analyzed for each PPS and the ITT (EMA and US FDA) using a mixed linear model with treatment 
group, baseline body weight (≤100 kg or >100 kg), geographic region (EU, US or ROW), the number of previous systemic therapies 
for psoriasis (<3 or ≥3), visit, and the treatment-by-visit interaction as fixed effects and baseline PASI score as a covariate. The treatment 
mean difference at Week 8 (for EMA) and Week 12 (for US FDA), along with CI are calculated. 
The 
variance-covariance 
matrix 
of 
unstructured 
form 
is 
used 
to

based on imputed data. 
The following subgroups will be assessed for endpoints which are specified above: 
1. body weight at baseline (≤100 kg or >100 kg) 
2. geographic region (EU, US or Rest of the World [ROW]) 
3. number of previous systemic therapies for psoriasis (<3 or ≥3) 
Percent change in PASI will be analyzed for each PPS and ITT (EMA and US FDA).

in means using estimates from an ANCOVA model adjusted for baseline PASI score and the stratification factors (patient’s body weight 
at baseline [≤100 kg, or >100 kg], geographic region [EU, US, or ROW] and the number of previous systemic therapies for psoriasis 
[<3 or ≥3]) except the subgroup factor being analyzed. 
18. SAFETY OUTCOMES 
There will be no statistical comparisons between the treatment groups for safety data, unless otherwise specified with the relevant section.  
18.1. 
ADVERSE EVENTS 
Adverse Events (AEs) will be coded using the latest version of MedDRA Dictionary. 
Treatment emergent adverse events (TEAEs) are defined as:  
• 
A new event that occurs during or after first dose of study treatment or,  
• 
Any event present at baseline that worsens in either intensity or frequency after first dose of study treatment. 
See Appendix 2 for handling of partial dates for AEs.  In the case where it is not possible to define an AE as treatment emergent or not, 
the AE will be classified by the worst case; i.e. treatment emergent.  
All Adverse Events started on the date of Week 28 dosing should be included in the Period 2. 
Only TEAEs will be summarized on Safety Analysis Set (SAF). 
An overall summary of number of subjects along with number of events within each of the categories described in the sub-section below, 
will be provided as specified in the templates.

Listings will include TEAEs and Non-TEAEs. 
Adverse events will be presented for Period 1, Period 2 and Overall period (Week 0 ~Week 52) 
18.1.1. 
ALL TEAES 
Incidence of TEAEs will be presented by System Organ Class (SOC) and Preferred Term (PT) and broken down further by relationship 
to study medication. 
Incidence of Non-TEAEs will be presented by System Organ Class (SOC) and Preferred Term (PT) 
18.1.1.1. 
Intensity 
Intensity will be classified according to CTCAE Grading V5.0 as (Grade1-Grade5). 
If a subject report a TEAE more than once within that SOC/ PT, the AE with the worst-case severity will be used in the corresponding 
severity summaries. 
• Grade 1: Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. 
• Grade 2: Moderate; minimal, local or non-invasive intervention indicated; limiting age-appropriate instrumental activities of   
daily living (ADL). 
• 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. 
Adverse Events falling under Grades 3 to 5 are considered as Severe Adverse events. 
 
18.1.1.2. 
Relationship to Study Medication 
 
Relationship as indicated by the Investigator, is classified as “Unrelated”, “Unlikely to be related”, “Possibly related”, “Probably related” 
or, “Not applicable”.  
Probably related and Possibly related are considered as Related to study medication, Unlikely and Unrelated are considered as  Unrelated 
to study medication. 
• 
“Unrelated” is used if there is not a reasonable possibility that the study treatment caused the AE. 
• 
“Unlikely to be related” suggests that only a remote connection exists between the study treatment and the AE. Other conditions, 
including chronic illness, progression or expression of the disease state or reaction to concomitant therapy, appear to explain the 
reported AE.  
• 
“Possibly related” suggests that the association of the AE with the study treatment is unknown. However, the AE is not reasonably

supported by other conditions. 
• 
“Probably related” conveys that there are facts, evidence, and/or arguments to suggest a causal relationship, rather than a relationship 
cannot be ruled out. 
All efforts should be made to classify the AE according to the above categories. 
• 
The category “not applicable” may be used for SAEs which happen prior to any procedures/dosing. 
If a subject report the same AE more than once within that SOC/ PT, the AE with the maximum intensity to study medication will be 
used in the corresponding relationship summaries.  
18.1.2. 
TEAES LEADING TO DISCONTINUATION OF STUDY MEDICATION 
For TEAEs leading to permanent discontinuation of study medication, summaries of incidence rates (frequencies and percentages) by 
SOC and PT will be prepared. 
TEAEs leading to permanent discontinuation of study medication will be identified by using the AE page (“Drug Withdrawn” chosen 
for “Action Taken with Study Treatment”) of the (e)CRF. 
18.1.3. 
TEAES LEADING TO WITHDRAWAL OF PATIENTS FROM STUDY 
For TEAEs leading to withdrawal from study, summaries of incidence rates (frequencies and percentages) by SOC and PT will be 
prepared. 
TEAEs leading to withdrawal of patients from study will be identified by using the AE page (“Drug Withdrawn” chosen for “Action 
Taken with Study Treatment”, at the same time, “Yes” chosen for “Caused Study Discontinuation”) of the (e)CRF. 
 
18.1.4. 
SERIOUS ADVERSE EVENTS 
Serious adverse events (SAEs) are those events recorded as” Serious” on the Adverse Events page of the (e)CRF. A summary of serious 
TEAEs by SOC and PT will be prepared. Listing for SAEs will also be provided. 
18.1.5. 
ADVERSE EVENTS LEADING TO DEATH 
TEAEs leading to death are those events which are recorded as ”Results in Death” on the Adverse Events page of the (e)CRF. A 
summary of TEAEs leading to death by SOC and PT will be prepared. Listing will also be provided.

• 
Hepatic injury: A hepatic injury is defined by the following alterations of hepatic laboratory parameters: 
• 
An elevation of AST and/or ALT ≥3-fold ULN combined with an elevation of total bilirubin ≥2-fold ULN measured in the 
same blood draw sample, or 
• 
An elevation of AST and/or ALT ≥3-fold ULN combined with an elevation of international normalized ratio (INR) >1.5, if 
INR measured, or 
• 
Marked peak aminotransferase (ALT, and/or AST) elevations ≥10-fold ULN. 
• 
These laboratory findings constitute a hepatic injury alert and the patients showing these laboratory abnormalities need to be 
followed up. In case of clinical symptoms of hepatic injury (icterus, unexplained encephalopathy, unexplained coagulopathy, 
right upper quadrant abdominal pain, etc.) without laboratory results (ALT, AST, and total bilirubin) available, the Investigator 
should 
make 
sure 
these 
parameters 
are 
analyzed, 
if 
necessary, 
in 
an 
unscheduled 
blood 
test. 
Hypersensitivity reactions; 
• 
Injection Site Reactions: An injection site reaction is any unfavorable or unintended sign that occurs at the IP injection site. 
Any adverse reaction (e.g., pain, erythema, and/or induration) should be recorded on the AE page of the eCRF; 
• 
Malignancies; 
• 
Neurologic or demyelinating events (e.g., progressive multifocal leukoencephalopathy; peripheral demyelination; posterior 
reversible encephalopathy syndrome [reversible Posterior Leukoencephalopathy Syndrome, RPLS]); have been reported with 
the administration of Stelara. Reversible Posterior Leukoencephalopathy Syndrome is a neurological disorder, which is not 
caused by demyelination or a known infectious agent. Reversible Posterior Leukoencephalopathy Syndrome can present with 
headache, seizures, confusion and visual disturbances. Conditions with which it has been associated include preeclampsia, 
eclampsia, acute hypertension, cytotoxic agents, and immunosuppressive therapy. Fatal outcomes have been reported 
(Prescribing Information for Stelara). In case RPLS is suspected, the treatment with the IP should be discontinued and the 
patient should be referred to neurologist for full evaluation and appropriate treatment.

The incidence of ADAs and neutralizing antibodies will be summarized by treatment group and visit and listed. 
Descriptive statistics for Binding and Neutralizing antibody titer will be provided for all available parameters at protocol specified visits 
using Number of subjects available at each assessment visit, Arithmetic Mean, Median, Minimum Maximum, quartiles and Geometric 
Mean. Summaries for both Actual and change from baseline will be presented. For geometric mean, the mean and the 95% CIs will be 
calculated on Log10 (titers/data), with subsequent antilog transformations applied. 
Incidence of ADA and Nabs will be summarized based on Period 1, Period 2 and overall period (Week0 to Week 52). 
20. PHARMACOKINETICS 
Changes to the procedures or events which may impact the quality of the PK data will be considered important protocol deviations or 
events and will be described within the clinical study report body text. These changes or events will include any circumstances that will 
alter the evaluation of the PK. Examples of deviations/events for PK include but may not be limited to sample processing errors that 
lead to inaccurate bioanalytical results, use of disallowed medications affecting PK, and/or inaccurate or incomplete dosing. Important 
deviations/events may potentially affect as little as a single data record (e.g. sample processing error) or an entire concentration-time 
profile.  In the case of a significant protocol deviation or event with impact on PK, the affected PK data will be excluded from PK 
analysis and/or descriptive statistics, as appropriate. Other changes to the procedures or events which do not impact the quality of the 
PK data will not be considered important protocol deviations. A common example of a protocol deviation which is not considered to be 
important is a missed blood sample or deviations from blood collection times at a non-critical time in the profile; such deviations may 
sometimes be adjusted for in the analysis, if appropriate, but will not result in exclusion of data from analysis. 
 
All PK concentrations will be reported and analyzed with the same precision as the source data provided by the bioanalytical laboratory 
regardless of how many significant figures or decimals the data carry. Derived PK parameters will be rounded for reporting purposes in 
by-subject listings.  Summary statistics of derived PK parameters will be performed by using the unrounded values and the statistical 
results will be rounded for reporting purposes. 
For most derived PK parameters, 3 significant digits will be used as the standard rounding procedure for reporting, with the following 
exceptions: 
• 
Parameters directly derived from source data (e.g. Cmax) will be reported and analyzed with the same precision as the source 
data. 
• 
Parameters derived from actual elapsed sample collection times (e.g. tmax) will be reported with a precision of 2 decimal places.

For the reporting of descriptive statistics, the means and SD will be presented to one digit more precision than the source data. The 
minimum, median, and maximum will be presented to the same precision as the source data.  Coefficients of variation will always be 
reported to 1 decimal place. 
20.1. 
SERUM CONCENTRATIONS  
Subjects with partial data will be evaluated on a case-by-case basis to determine if sufficient data are available for reliable estimation of 
PK parameters. 
 
A listing of PK blood sample collection times as well as derived sampling time deviations will be provided. Plasma concentrations will 
be summarized for each treatment and measurement time using descriptive statistics including n, mean, SD, coefficient of variation 
(CV%), median, minimum, and maximum.  Concentration summaries by treatment and body weight category (Week 0 to Week 28 only) 
will also be provided. Concentration summaries by treatment and ADA status (binding and neutralizing) will also be provided. For these 
summaries, a subject’s ADA status will be classified 2 ways: (1) An Overall categorization will be used where a subject’s status will be 
classified as positive if they have a positive result at any time over 0- to 52-week measurement period; otherwise it will be classified as 
negative. (2) A by-time-point categorization will be used where a subject’s status will be classified at each time point based on whether 
they have a positive or negative result at that time point; if there is no antibody measurement at a time point or if the antibody result is 
missing or inconclusive, the last reliable result will be carried forward to this time point. 
Concentrations that are below the limit of quantitation (BLQ) will be treated as zero for the computation of descriptive statistics. Samples 
that are collected outside the protocol-specified windows (Table 1 of the protocol) will be excluded from descriptive statistics. A subject 
listing of all concentration-time data for each treatment will be presented.  For subjects who switch from Stelara to DMB-3115 treatment 
at Week 28, concentrations up to and including Week 28 will be summarized under Stelara treatment, but post-Week 28 concentrations 
will be listed and summarized separately. 
 
Figures of arithmetic mean concentration-time data (±SD on linear plot) will be presented for each treatment on linear and semi-
logarithmic scales for the 0- to 4-week period. Figures of arithmetic mean (±SD) concentration-time data will also be presented for each 
treatment on linear scale for the 0- to 52-week period (separate figures will show subjects who switched from Stelara to DMB-3115 at 
Week 28 either included or excluded for time points beyond Week 28). Similar figures will also be included which further subset these 
treatments by ADA status (binding and neutralizing). Arithmetic mean figures by treatment and body weight category (Week 0 to Week 
28) will also be provided. Individual subject concentration-time data will be graphically presented on linear and semi-logarithmic scales 
(0- to 4-week period) and linear scale (0- to 52-week period).  Individual concentrations which are BLQ will be displayed as zero in the 
graphic presentations on linear scale, but will not be plotted on semi-logarithmic scale.  Means which fall below the LLOQ will be

displayed as zero in the graphic presentations on linear scale, but will not be plotted on semi-logarithmic scale. 
Handling of the concentration-time profiles for statistical summaries with anomalous predose concentrations of greater than 5.00% of 
Cmax prior to the first dose will follow the handling conventions of the PK parameters as described in Section 20.2. 
20.2. 
SERUM PARAMETERS  
Pharmacokinetic parameters will be calculated for the first dose. For PK parameter calculations, predose samples that are BLQ or 
missing will be assigned a numerical value of zero.  Any other BLQ concentrations will be assigned a value of zero if they precede 
quantifiable samples in the initial portion of the profile.  A BLQ value that occurs between quantifiable data points, especially prior to 
Cmax, will be evaluated to determine if an assigned concentration of zero makes sense, or if exclusion of the data is warranted.  Following 
Cmax, BLQ values embedded between 2 quantifiable data points will be treated as missing when calculating PK parameters.  If a BLQ 
value occurs at the end of the collection interval (after the last quantifiable concentration), it will be treated as zero.  If consecutive BLQ 
concentrations are followed by quantifiable concentrations in the terminal portion of the concentration curve, these quantified values 
will be excluded from the PK analysis by setting them to missing, unless otherwise warranted by the concentration-time profile.  
Any anomalous concentration values observed prior to the first dose will be identified in the study report and used for the computation 
of PK parameters. If the anomalous concentration is greater than 5.00% of Cmax (when rounded to 3 significant digits), the PK parameters 
for the affected subject profile will be calculated and reported in the listing but excluded from statistical summaries and analyses.  
Similarly, PK concentrations for the affected profile will be excluded from statistical summaries. 
The following PK parameters will be estimated for the first dose (Week 0) by non-compartmental methods using actual elapsed time 
from dosing (rounded to 2 decimal places).  A minimum of 3 quantifiable concentration-time data points will be required for calculation 
of PK parameters). 
 
Cmax 
Maximum concentration, obtained directly from the observed concentration versus time data.  
tmax 
Time of maximum concentration, obtained directly from the observed concentration versus 
time data. 
AUC(w0-w4) 
Area under the concentration-time curve from Week 0 (predose) to Week 4, calculated by 
linear up/log down trapezoidal summation.  Actual elapsed time and associated concentration 
at Week 4 will be used for the calculation. If the Week-4 sample is collected outside the 
protocol-specified window (see Table 1 of protocol), the AUC(w0-w4) for the affected subject 
profile will be calculated and reported in the listing but excluded from statistical summaries 
and analyses.
