SUMMARY 
DV0002 is a multicenter, open-label, randomized substudy in adult subjects with moderate to 
severe chronic plaque psoriasis (PSO) to evaluate the safe and effective use of 4 single-use 
disposable self-injection investigational devices for the subcutaneous (sc) administration of 
bimekizumab solution (the investigational medicinal product [IMP]). The 4 self-injection devices 
to be tested are the 1mL bimekizumab safety syringe (bimekizumab-SS-1mL), the 
1mL bimekizumab auto injector (bimekizumab-AI-1mL), the 2mL bimekizumab safety syringe 
(bimekizumab-SS-2mL), and the 2mL bimekizumab auto injector (bimekizumab-AI-2ml). 
DV0002 is a substudy of PS0014, which is a multicenter, open-label, long-term safety study for 
subjects with moderate to severe chronic plaque PSO who complete 1 of the Phase 3 feeder 
studies (PS0008, PS0009, or PS0013). The PS0014 study will evaluate the long-term safety, 
tolerability, and efficacy of bimekizumab in subjects with PSO, and study personnel qualified in 
sc injection technique will administer bimekizumab to subjects in a 1mL True North prefilled 
syringe (referred to throughout this protocol as the 1mL PFS). In the DV0002 substudy, subjects 
will self-administer bimekizumab at DV0002 Baseline and at DV0002 Week 8. 
During the Treatment Period of DV0002, subjects will receive either bimekizumab 320mg every 
8 weeks (Q8W) or bimekizumab 320mg every 4 weeks (Q4W), based on their assigned dosing at 
Baseline of PS0014. The same interactive response technology (IRT) will be used for both 
studies (DV0002 and PS0014). The dose regimen will remain stable for the entire Treatment 
Period of DV0002.  
In the DV0002 substudy, subjects will be assigned to 1 of the 4 self-injection devices and will 
self-administer bimekizumab only at DV0002 Baseline and at DV0002 Week 8 after training, 
regardless of their assigned dosing regimen. Bimekizumab will be administered by study 
personnel at DV0002 Week 4 and DV0002 Week 12 for subjects in the Q4W dosing arm and at 
DV0002 Week 16 for both dosing arms. A safety follow-up (SFU) telephone call will occur 
1 week after the last self-administration (at DV0002 Week 9). After Week 16 in the DV0002 
substudy, subjects will continue in PS0014. 
The primary objective of the DV0002 substudy is to evaluate, for each device, the ability of 
subjects with moderate to severe chronic plaque PSO to safely and effectively self-inject 
bimekizumab 8 weeks after training in the self-injection technique. The primary outcome 
variable is the percentage of subjects able to self-administer safe and effective injections using 
the bimekizumab-SS-1mL, bimekizumab-AI-1mL, bimekizumab-SS-2mL, or 
bimekizumab-AI-2mL device 8 weeks after training in self-injection technique (DV0002 
Week 8).  
Safe and effective self-injection will be evaluated by the study personnel and is defined as: 
 Complete dose delivery: Subject self-injects the complete dose of bimekizumab as confirmed 
by a visual inspection of the device, which shows that the IMP is delivered completely (ie, 
container is empty), and 
 No adverse device effects (ADEs) that would preclude continued use of the device for 
self-injection (ie, no serious ADEs [SADEs] and/or ADEs leading to withdrawal from the 
DV0002 substudy)

The secondary study objectives and other study objectives are provided in Section 3.2 and 
Section 3.3, respectively. Of note, one of the other study objectives is to assess trough 
pharmacokinetic (PK) levels associated with self-injection using the investigational device, 
injection by study personnel, injection site (abdomen or thigh), and body mass index (BMI) 
category (by tertile). The secondary outcome variable, other outcome variables, and the other 
safety variable are listed in Section 4.1.2, Section 4.1.3.1, and Section 4.1.3.3, respectively.  
The DV0002 substudy consists of 2 cohorts. The 1mL device cohort will evaluate 2 different 
self-injection investigational devices: the bimekizumab-SS-1mL and the bimekizumab-AI-1mL. 
The 2mL device cohort will also evaluate 2 different self-injection investigational devices: the 
bimekizumab-SS-2mL and the bimekizumab-AI-2ml. The data for each cohort will be analyzed 
and reported separately. 
1mL Device Cohort 
Subjects who enroll in the 1mL device cohort of DV0002 will begin the DV0002 substudy and 
the PS0014 study at the same time, and as such, the Baseline visit and all subsequent study visits 
(up to Week 16) will be the same. 
To compensate for subjects who have different study treatments between the feeder studies and 
DV0002, the 1mL device cohort of the DV0002 substudy is planned to enroll approximately 
200 subjects (100 subjects per device arm) to ensure that approximately 50 subjects per device 
arm are evaluable for steady state trough PK level analyses. Within each device arm, subjects 
will be divided into tertiles by BMI; there will be approximately 33 subjects per tertile, which is 
expected to yield approximately 16 to 17 subjects per tertile who are evaluable for steady state 
trough PK level analyses.  
In the DV0002 substudy 1mL device cohort, the 320mg bimekizumab dose will be administered 
as two 160mg injections with either 2 bimekizumab-SS-1mL devices or 2 bimekizumab-AI-1mL 
devices. Each self-injection will be evaluated by study personnel for safety and effectiveness 
using the above criteria. The endpoint of safe and effective self-injection will be met only if both 
self-injections are determined to be safe and effective.  
2mL Device Cohort 
Subjects who participated in the 1mL device cohort are not eligible to participate in the 
2mL device cohort. To allow flexible enrollment, subjects may be randomized in the 2mL device 
cohort at the PS0014 Week 24, Week 28, or Week 32 visit for subjects receiving bimekizumab 
Q4W or the PS0014 Week 24 or Week 32 visit for subjects receiving bimekizumab Q8W.  
For evaluation of the 2mL device, it is planned to enroll approximately 100 subjects; each device 
arm (bimekizumab-SS-2mL or bimekizumab-AI-2mL) will consist of approximately 50 subjects.  
In the DV0002 substudy, for the 2ml devices, the 320mg bimekizumab dose will be 
self-administered as 1 injection with either 1 bimekizumab-SS-2mL or 1 bimekizumab-AI-2mL 
device. Each self-injection will be evaluated for safety and effectiveness by study personnel 
using the above criteria. The endpoint of safe and effective self-injection will be met if the single 
self-injection is determined to be safe and effective.

INTRODUCTION 
Psoriasis is a common, chronic inflammatory disease characterized by a series of linked cellular 
changes in the skin. Bimekizumab (UCB4940; the IMP) is an engineered, humanized full length 
monoclonal antibody of immunoglobulin G1 subclass that selectively and potently inhibits the 
activity of interleukin (IL)-17A and IL-17F in vitro. Interleukin-17A and IL-17F are key 
proinflammatory cytokines believed to play important roles in autoimmune and inflammatory 
diseases. Bimekizumab is being developed for the treatment of patients with inflammatory 
diseases such as psoriatic arthritis, PSO, and axial spondyloarthritis. 
It is important for patients who may use bimekizumab for the treatment of moderate to severe 
chronic plaque PSO to have options for the self-injection of bimekizumab that fit their needs and 
preferences. Whilst some patients may prefer to manually regulate various tasks comprising the 
self-injection process (eg, needle visibility, skin penetration by needle, speed of self-injection), 
others may prefer a more automated process (eg, do not wish to see the needle, desire an 
automatic injection). UCB therefore intends to provide patients with different options to 
self-inject bimekizumab. 
The DV0002 study is a substudy of the PS0014 study. PS0014 will evaluate the long-term safety, 
tolerability, and efficacy of bimekizumab in subjects with moderate to severe chronic plaque 
PSO; study personnel will administer bimekizumab in a 1mL PFS. The DV0002 substudy will 
evaluate 4 self-injection investigational devices: the bimekizumab-SS-1mL, the 
bimekizumab-AI-1mL, the bimekizumab-SS-2mL, and the bimekizumab-AI-2ml. Full 
descriptions of the 4 devices are provided in Section 7.1.1, Section 7.1.2, Section 7.1.3 and 
Section 7.1.4, respectively. 
The proposed substudy is planned to demonstrate that adult subjects with moderate to severe 
chronic plaque PSO can safely and effectively self-inject bimekizumab using the bimekizumab-
SS-1mL, bimikizumab-AI-1mL, bimekizumab-SS-2mL, or bimekizumab-AI-2mL device. 
For subjects in the 1mL device cohort, subjects will be randomly assigned in a 1:1 ratio to 
perform self-injection using either the bimekizumab-SS-1mL or the bimekizumab-AI-1mL. 
Subjects who participated in the 1mL device cohort of DV0002 are not eligible to enroll in the 
2mL device cohort. 
Once the 1mL device cohort has finished enrolling, the 2mL device cohort will start enrolling. 
Subjects in this cohort will be randomly assigned in a 1:1 ratio to perform self-injection using 
either the bimekizumab-SS-2mL or bimekizumab-AI-2mL device.

STUDY VARIABLES 
4.1 
Outcome variables 
4.1.1 
Primary outcome variable 
The primary outcome variable is the percentage of subjects able to self-administer safe and 
effective injections using the bimekizumab-SS-1mL, bimekizumab-AI-1mL, 
bimekizumab-SS-2mL, or bimekizumab-AI-2mL, 8 weeks after training in self-injection 
technique. Safe and effective self-injection will be evaluated by the study personnel and is 
defined as: 
 Complete dose delivery: Subject self-injects the complete dose of bimekizumab as confirmed 
by a visual inspection of the device which shows that the IMP is delivered completely 
(ie, container is empty), and 
 No ADEs that would preclude continued use of the device for self-injection (ie, no SADEs 
and/or ADEs leading to withdrawal from the DV0002 substudy). 
In the DV0002 substudy, for the 1mL devices, the 320mg bimekizumab dose will be 
administered as two 160mg injections with either 2 bimekizumab-SS-1mL devices or 
2 bimekizumab-AI-1mL devices. Each self-injection will be evaluated for safety and 
effectiveness by study personnel using the above criteria. The endpoint of safe and effective 
self-injection will be met only if both self-injections are determined to be safe and effective. 
For the 2ml devices, the 320mg bimekizumab dose will be administered as 1 injection with either 
1 bimekizumab-SS-2mL or 1 bimekizumab-AI-2mL device. Each self-injection will be evaluated 
for safety and effectiveness by study personnel using the above criteria. The endpoint of safe and 
effective self-injection will be met if the single self-injection is determined to be safe and 
effective. 
4.1.2 
Secondary outcome variable 
The secondary outcome variable is the percentage of subjects able to self-administer safe and 
effective injections using the bimekizumab-SS-1mL, bimekizumab-AI-1mL, 
bimekizumab-SS-2mL, or 1 bimekizumab-AI-2mL at DV0002 Baseline (the first self-injection 
visit, immediately after training in self-injection technique). Safe and effective self-injection will

be evaluated by study personnel and is defined as for the primary outcome variable (see 
Section 4.1.1). 
4.1.3 
Other variables 
4.1.3.1 
Outcome variables 
The other outcome variables are: 
 Responses to pre-injection SIAQ (versions 2.0 and 2.1) at DV0002 Baseline. 
Whenever SIAQ is assessed, version 2.0 of the SIAQ will be used to assess 
bimekizumab-SS-1mL and bimekizumab-SS-2mL and version 2.1 of the SIAQ will be used 
to assess bimekizumab-AI-1mL and bimekizumab-AI-2mL (see Section 9.1). 
 Responses to post-injection SIAQ (versions 2.0 and 2.1) by visit following self-injection 
using the assigned device at DV0002 Baseline and Week 8. 
 Injection site pain (using a VAS; 100mm) by visit after self-injection using the assigned 
device at DV0002 Baseline and Week 8. 
 Percentage of used devices identified as having structural or mechanical integrity issues after 
completion of self-injection. This is based on a visual examination of the device that shows 
clear evidence of damage and/or compromised structural or mechanical integrity.  
4.1.3.2 
Pharmacokinetic variable 
The PK variable is trough PK (bimekizumab) levels associated with self-injection using the 
investigational device, injection by study personnel, injection site (abdomen or thigh), and BMI 
category (by tertile). Trough levels will be assessed at DV0002 Baseline, Week 4, Week 8, and 
Week 12 for subjects who receive bimekizumab Q4W and trough levels will be assessed at 
DV0002 Baseline, Week 8, and Week 16 for subjects who receive bimekizumab Q8W. 
4.1.3.3 
Safety variable 
The other safety variable is the occurrence of ADEs. Additional safety and tolerability variables 
will be collected as described in the PS0014 study protocol.

STUDY DESIGN 
5.1 
Study description 
DV0002 is a Phase 3 open-label, randomized, noncomparator, North America-only substudy to 
PS0014. PS0014 will evaluate the long-term safety, tolerability, and efficacy of bimekizumab in 
subjects with moderate to severe chronic plaque PSO, and study personnel will administer 
bimekizumab to subjects in a 1mL PFS. In the DV0002 substudy, the safe and effective use of 
the bimekizumab-SS-1mL, bimekizumab-AI-1mL, bimekizumab-SS-2mL, or the 
bimekizumab-AI-2mL for the sc self-injection of bimekizumab solution by subjects with PSO 
will be evaluated.  
Subjects from selected sites in the PS0014 feeder studies PS0008, PS0009, and PS0013 will be 
eligible for the DV0002 substudy. At DV0002 Baseline, each subject will be provided with 
training in self-injection and will receive the instructions for use (IFU) and any other applicable 
training materials.

1mL Device Cohort 
For the 1mL device cohort, subjects in the DV0002 substudy will perform self-injections at 
Baseline (corresponding to the Baseline Visit of PS0014) with a subsequent self-injection at 
Week 8 (corresponding to Week 8 of PS0014).  
During the 16-week Treatment Period of DV0002, subjects will receive either bimekizumab 
320mg Q8W or bimekizumab 320mg Q4W, based on their assigned dosing at Baseline 
(Table 5-1). Baseline for DV0002 and Baseline for PS0014 will occur at the same time, and the 
same interactive response technology (IRT) will be used for both studies. The 320mg 
bimekizumab dose will be administered as two 160mg injections, and both injections will be 
either self-administered using the investigational device (at Baseline and Week 8) or 
administered by study personnel using the 1mL PFS (at Week 4 and Week 12 for subjects in the 
Q4W dosing arm and at Week 16 for both dosing arms). This dose regimen will remain stable for 
the entire 16-week Treatment Period of DV0002, as per PS0014 design. The DV0002 substudy 
will evaluate 2 self-injection investigational devices: the bimekizumab-SS-1mL and the 
bimekizumab-AI-1mL.  
Eligible subjects (PS0014 entry criteria and Section 6 DV0002 entry criteria) will be randomly 
assigned in a 1:1 ratio to perform self-injection using either the bimekizumab-SS-1mL or the 
bimekizumab-AI-1mL (see Section 7.10). Regardless of the assigned dose regimen, subjects will 
perform self-injection with the assigned device only at Baseline (corresponding to the Baseline 
Visit of PS0014) and at Week 8 (corresponding to Week 8 of PS0014).

using the investigational device; SP=study personnel performing injection using the 1mL pre-filled syringe  
Note: For S injections, the 320mg bimekizumab dose will be administered as two 160mg injections (using 
2 bimekizumab-SS-1mL or 2 bimekizumab-AI-1mL). For SP injections, the 320mg bimekizumab dose will be 
administered as two 160mg injections (using prefilled syringes). Both injections will be administered in the 
same manner (eg, both self-administered injections or both study personnel-administered injections), but each 
injection will be administered at a separate injection site and rotation between injection sites should be 
observed. 
Note: For the 1mL device cohort, visits in the DV0002 substudy correlate with the same visit in the PS0014 study 
(ie, the DV0002 Baseline Visit is the PS0014 Baseline Visit). Dose regimen will be assigned at Baseline, and 
the same interactive response technology will be used for both studies. 
The bimekizumab administration schedule optimizes the collection of PK trough level data 
within the constraints of a short treatment period and a Q4W and Q8W dosing regimen. At 
Weeks 4, 12, and 16, subjects on the Q4W dosing regimen will be injected by study personnel 
with 2 injections each of 160mg bimekizumab using a 1mL PFS (ie, the same device as that used

in PS0014). For these subjects, the Q4W administration schedule will provide PK trough data 
associated with injection by: 
 Study personnel using the 1mL PFS from PK samples collected (before self-injection) at 
Baseline and Week 8 (ie, PK data from 2 timepoints) 
 Subject self-injection using the assigned device from PK samples collected (before 
injection by study personnel) at Week 4 and Week 12 (ie, PK data from 2 timepoints) 
At Baseline and Week 8, subjects on the Q8W dosing regimen will self-inject 2 injections each 
of 160 mg bimekizumab using the assigned device (ie, bimekizumab-SS-1mL or the 
bimekizumab-AI-1mL). For these subjects, the Q8W administration schedule will provide PK 
trough data associated with injection by: 
 Study personnel using the 1mL PFS from PK samples collected (before self-injection) at 
Baseline (ie, PK data from 1 timepoint) 
 Subject self-injection using the assigned device from PK samples collected (before 
self-injection) at Week 8 and (before injection by study personnel) at Week 16 (ie, PK 
data from two timepoints) 
In addition to self-injections, DV0002 substudy-specific assessments (eg, study personnel 
evaluation, SIAQ responses, VAS for injection site pain, and PK analyses; see Section 5.2) will 
be performed from Baseline through Week 16 (inclusive). An SFU telephone call will occur 
1 week after the last self-administration (at Week 9).  
After Week 16 in the DV0002 substudy, subjects will continue in PS0014 (the next visit after 
DV0002 completion will be the Week 20 Visit in PS0014). Studies DV0002 and PS0014 will 
share a common database/electronic Case Report form (eCRF) system (including common 
adverse event [AE] reporting) and a common IRT. 
Subjects who are withdrawn from DV0002 but continue their PS0014 study participation will be 
required to perform an SFU telephone call 1 week after their final DV0002 dosing visit (see 
Section 6.3). Subjects who are withdrawn from bimekizumab treatment (PS0014 study) during 
the course of DV0002 will also be required to follow the PS0014 withdrawal procedures. 
2mL Device Cohort 
To allow flexible enrollment, subjects may be randomized in the 2mL device cohort at the 
PS0014 Week 24, Week 28, or Week 32 visit for subjects receiving bimekizumab Q4W or the 
PS0014 Week 24 or Week 32 visit for subjects receiving bimekizumab Q8W.  
For the 2mL device cohort, subjects will perform self-injections at DV0002 Baseline with a 
subsequent self-injection 8 weeks after training. The 2mL device cohort will evaluate 
2 self-injection devices: the bimekizumab-SS-2mL and the bimekizumab-AI-2mL. 
During the Treatment Period of DV0002, subjects will receive either bimekizumab 320mg Q8W 
or bimekizumab 320mg Q4W, based on their assigned dosing at Baseline of PS0014 (Table 5-3). 
In the 2mL device cohort, Baseline for DV0002 will occur at the PS0014 Week 24, Week 28, or 
Week 32 visit for subjects receiving bimekizumab Q4W or the PS0014 Week 24 or Week 32 
visit for subjects receiving bimekizumab Q8W. The same IRT will be used for both studies. The 
320mg bimekizumab dose will either be self-administered as 1 injection using the assigned

the course of DV0002 will also be required to follow the PS0014 withdrawal procedures. 
5.1.1 
Study duration per subject 
The maximum DV0002 substudy duration will be 16 weeks for each subject. Subjects will then 
continue to receive treatment in PS0014 for the duration of the PS0014 study. 
The end of the DV0002 substudy is defined as the date on which the last subject completes 
his/her Week 16 Visit or withdraws from the study. 
5.1.2 
Planned number of subjects and sites 
For evaluation of the 1mL device, it is planned to enroll approximately 200 subjects; each device 
arm (bimekizumab-SS-1mL, bimekizumab-AI-1mL) will consist of approximately 100 subjects.  
Once the 1mL device cohort has finished enrolling, the 2mL device cohort will start enrolling. 
For evaluation of the 2mL device, it is planned to enroll approximately 100 subjects; each device 
arm (bimekizumab-SS-2mL or bimekizumab-AI-2mL) will consist of approximately 50 subjects.  
It is anticipated that this study will involve up to 80 sites in North America.

The study schematic diagram for DV0002 1 mL device cohort is presented in Figure 5‒1, and the 
2mL device cohort is presented in Figure 5‒2.

BL=Baseline; Q4W=every 4 weeks; Q8W=every 8 weeks; self-inject=self-injection; SFU=safety follow-up; 
Wk=week 
Note: Phase 3 feeder studies include PS0008, PS0009, and PS0013. 
Note: Subjects will receive 320mg bimekizumab either Q4W or Q8W. Bimekizumab will be self-administered only 
at Baseline and at Week 8 (study personnel will administer bimekizumab at other visits, as applicable). 
Note: For the 1mL device cohort, subjects will begin the DV0002 substudy and the PS0014 study at the same time; 
therefore, Baseline for DV0002 corresponds to Baseline for PS0014.

BL=Baseline; Q4W=every 4 weeks; Q8W=every 8 weeks; self-inject=self-injection; SFU=safety follow-up; 
WK=week 
Note: Subjects will receive 320mg bimekizumab either Q4W or Q8W. Bimekizumab will be self-administered only 
at DV0002 Baseline and 8 weeks after training (study personnel will administer bimekizumab at other visits). 
a For the 2mL device cohort, subjects will not begin the DV0002 substudy and the PS0014 study at the same time. 
Baseline for DV0002 corresponds to the PS0014 Week 24, Week 28, or Week 32 visit for subjects receiving 
bimekizumab Q4W and to the PS0014 Week 24 or Week 32 visit for subjects receiving bimekizumab Q8W. 
5.4 
Rationale for study design and selection of dose 
DV0002 is a Phase 3, randomized, multicenter, open-label study for subjects with moderate to 
severe chronic plaque PSO who will self-inject bimekizumab. DV0002 is a substudy of PS0014; 
PS0014 is a multicenter, open-label, long-term study to evaluate the safety, tolerability, and

efficacy of bimekizumab in subjects with moderate to severe chronic plaque PSO who complete 
1 of the Phase 3 feeder studies (PS0008, PS0009, or PS0013).  
It is expected that most individuals who will use commercial bimekizumab for the treatment of 
moderate to severe chronic plaque PSO will self-inject bimekizumab and also that these 
individuals will prefer to have options for the self-administration of their medication. DV0002 
will therefore evaluate the safe and effective use of 4 different self-injection investigational 
devices in 2 cohorts: the 1mL device cohort and the 2mL device cohort. The 1mL device cohort 
will evaluate the bimekizumab-SS-1mL and bimekizumab-AI-1mL investigational devices. The 
2mL device cohort will evaluate the bimekizumab-SS-2mL and bimekizumab-AI-2mL 
investigational devices. In addition, DV0002 will assess trough PK levels associated with 
self-injection using the investigational device, injection by study personnel using the 1mL PFS, 
injection site (abdomen or thigh), and BMI category (by tertile).

SELECTION AND WITHDRAWAL OF SUBJECTS 
6.1 
Inclusion criteria 
To be eligible for DV0002, subjects must meet all of the following additional criteria: 
1. An Institutional Review Board (IRB) approved written Informed Consent form (ICF) for 
DV0002 is signed and dated by the subject.  
2. Subject fulfills all inclusion criteria for the PS0014 study. 
3. Subject is considered reliable and capable of adhering to the DV0002 protocol (eg, able to 
understand and complete questionnaires, able to use investigational device according to the 
IFU, and able to adhere to the visit schedule) according to the judgment of the Investigator.  
4. Subject is willing to self-inject. 
6.2 
Exclusion criteria 
Subjects are not permitted to enroll in DV0002 if any of the PS0014 study exclusion criteria are 
met. Subjects who participated in the 1mL device cohort of DV0002 are not eligible to enroll in 
the 2mL device cohort. 
6.3 
Withdrawal criteria 
Since DV0002 is a substudy of PS0014, all DV0002 withdrawal criteria are captured in the 
PS0014 protocol. There are no additional DV0002-specific withdrawal criteria beyond those that 
are described in PS0014. Subjects are free to withdraw from DV0002 at any time, without 
prejudice to their continued care. Subjects who withdraw from DV0002 but remain eligible for 
PS0014 (ie, subjects who have a medical condition or personal preference that precludes further 
self-injection) may continue in PS0014. These subjects must perform an SFU telephone call 
1 week after their final DV0002 dosing visit.  
Subjects who are withdrawn from bimekizumab treatment (PS0014 study) during DV0002 will 
also be required to follow the PS0014 withdrawal procedures.

INVESTIGATIONAL MEDICINAL PRODUCT AND 
INVESTIGATIONAL DEVICE 
In the DV0002 substudy, the term IMP refers to the bimekizumab drug product. The term 
investigational device refers to 4 different self-injection investigational devices 
(bimekizumab-SS-1mL, bimekizumab-AI-1mL, bimekizumab-SS-2mL, and 
bimekizumab-AI-2mL) that are comprised of drug product (IMP) associated with a functional 
secondary packaging. 
7.1 
Description of investigational devices 
At DV0002 Baseline, each subject will be provided with self-injection training and IFU for the 
appropriate device.  
7.1.1 
Bimekizumab-SS-1mL 
The bimekizumab-SS-1mL, shown in Figure 7-1, consists of the naked PFS (primary packaging 
containing bimekizumab drug product for all Phase 3 studies) and a customized
safety syringe for sc bimekizumab administration. 
The naked PFS is a glass, 1mL long, primary container with small round flange and a 27G 
half-inch staked needle containing 1mL of bimekizumab. The
safety syringe is a 
single-use platform device with a passive needle stick safety mechanism. To enhance the device 
usability,

permitted. 
During the study (at Baseline and Week 8), 2 bimekizumab-SS-1mL devices will be used to 
administer 160mg injections of bimekizumab (320mg total). To use the bimekizumab-SS-1mL, 
the overcap is removed and the plunger rod is fully depressed, which empties the syringe 
contents through the needle. When the plunger rod reaches its final position the needle safety 
retraction mechanism is activated, which retracts the sleeve, syringe, and plunger rod and holds 
the needle safely within the body molding.  
Additional instructions for device use, including the injection angle, are provided in the IFU. 
7.1.2 
Bimekizumab-AI-1mL 
The bimekizumab-AI-1mL, shown in Figure 7-2, consists of the naked PFS (primary packaging 
containing bimekizumab drug product used for all Phase 3 studies and in the

 320mg bimekizumab, Q4W. 
Regardless of the assigned dose regimen, subjects will perform self-injection with the assigned 
device only at Baseline and at Week 8. For the 1mL device cohort, the 320mg bimekizumab dose 
will be administered as two 160mg injections with either 2 bimekizumab-SS-1mL or 
2 bimekizumab-AI-1mL devices. At all visits except Baseline and Week 8, the 
320mg bimekizumab dose will be administered as two 160mg injections in a 1mL PFS by study 
personnel (ie, the same administration manner and device used in PS0014).  
The investigational devices will be used as described in the IFU. Subjects will be observed onsite 
for 30 minutes after self-injection with bimekizumab for any AEs. Subjects will be asked to 
contact the designated site personnel in case any AEs occur outside of the site visits. Of note, 
reported AEs related to IMP will be assessed within PS0014 and reported ADEs and device 
deficiencies will be assessed within DV0002. 
2mL Device Cohort 
For the 2mL device Cohort, IMP will be supplied in 2 investigational devices: 
bimekizumab-SS-2mL or bimekizumab-AI-2mL. 
The IMP will be administered according to the schedule shown in Table 5-2. Subjects will be 
assigned to the use of 1 device and will receive the following doses of IMP based on their dosing 
regimen in PS0014: 
 320mg bimekizumab, Q8W or 
 320mg bimekizumab, Q4W. 
Regardless of the assigned dose regimen, subjects will perform self-injection with the assigned 
device only at DV0002 Baseline and 8 weeks after training with the investigational device. For 
the 2mL device cohort, 320mg bimekizumab dose will be administered as 1 injection with either 
the bimekizumab-SS-2mL device or the bimekizumab-AI-2mL device. For subjects who receive 
bimekizumab Q4W, the bimekizumab dose at Week 4 will be administered as 
two 160mg injections in a 1mL PFS by study personnel (ie, the same administration manner used 
in PS0014).  
The devices will be used as described in the IFU. Subjects will be observed onsite for 30 minutes 
after self-injection with bimekizumab for any AEs. Subjects will be asked to contact the

Good Manufacturing Practice and will include any locally required statements. If necessary, 
labels will be translated into the local language.  
7.5 
Handling and storage requirements 
The investigational devices that house IMP must be securely stored at 2ºC to 8ºC (ie, in a 
refrigerator), that is either in a locked room or in the pharmacy. Appropriate storage conditions 
must be ensured by controlling refrigerator temperature by using either an automated 
temperature monitoring and recording system or a minimum/maximum thermometer and 
completing a daily temperature log in accordance with local requirements. If an out-of-range 
temperature is noted, the Sponsor or designee must be notified so that a determination can be 
made whether the product should be used or not.  
The Investigator or hospital pharmacist is responsible for the appropriate storage and 
accountability of the investigational device at the site, as well as, for the documentation of 
appropriate storage and accountability. Refer to the IMP Handling Manual for additional 
information on handling and storage requirements. 
7.6 
Drug and device accountability 
The Investigator will receive numbered treatments that will be assigned to eligible subjects by an 
IRT at Baseline. All IMP administrations will be observed by the Investigator or his/her 
appropriately trained designee. 
Appropriate accountability forms that reflect the receipt and use of the IMP and the 
investigational devices will be supplied to the investigational site. Details of any loss of the 
self-injection investigational devices due to breakage or wastage, non-use, destruction at the 
study site, or return to the Sponsor or designee must also be recorded on these forms. All 
supplies and pharmacy documentation must be made available throughout the study for UCB (or 
designee) to review. 
The Investigator (or designee) is responsible for retaining all used, unused, and partially used 
IMP and investigational devices until returned to UCB. Used or partially used devices are to be 
stored at room temperature in a secured area and may only be destroyed following UCB’s 
instruction. Devices with noted deficiencies are to be returned to UCB immediately. The 
Investigator may assign some of the Investigator’s duties for drug accountability at the study site 
to an appropriate pharmacist/designee.  
The IMP and investigational devices intended for the study cannot be used for any other purpose 
than that described in this protocol. 
7.7 
Procedures for monitoring subject compliance 
During the Treatment Period of this study, IMP administration (either self-administration or 
study personnel-administration) will be performed in the clinic and observed by the Investigator 
or his/her designee. Subject compliance will be reported in the PS0014 study.

PS0014 and DV0002 and to maintain subject confidentiality. At study visits, an IRT will assign 
the applicable subject kits of IMP. Further instructions will be provided in the IRT manual. 
The IRT will generate individual assignments for the self-injection investigational devices. 
Eligible subjects will be assigned to the investigational devices based on a predetermined 
production randomization and/or packaging schedule provided by UCB (or designee). In the 
1mL device cohort, all eligible subjects will be randomly assigned to perform self-injection using 
either the bimekizumab-SS-1mL or the bimekizumab-AI-1mL at a 1:1 ratio. The IRT will 
allocate kit numbers to the subject based on the subject number during the study. 
Once the 1mL device cohort has finished enrolling, the 2mL device cohort will start enrolling. 
Eligible subjects in the 2mL device cohort will be randomly assigned to perform self-injection 
using either the bimekizumab-SS-2mL or bimekizumab-AI-2mL device at a 1:1 ratio. The IRT

ASSESSMENT OF SELF-INJECTION 
Evaluation of dose delivery and safe self-injection will be performed as described for the primary 
outcome variable (Section 4.1.1). 
9.1 
Assessment of self-injection experience by SIAQ 
The SIAQ will be used to assess the subject’s self-injection experience. 
The SIAQ was developed by UCB to assess the perceived advantages and the potential 
limitations of self-injection of an sc medication (Keininger and Coteur, 2011). The pre-injection 
SIAQ is composed of 7 items grouped into 3 domains (feelings about injection, self-confidence, 
and satisfaction with the current mode of administration). The post-injection SIAQ is composed 
of 21 items grouped into 6 domains (feelings about injection, self-image, self-confidence, 
injection site reactions, ease of use, and satisfaction with self-injection). The pre-injection SIAQ 
will be completed at Visit 1, and the post-injection SIAQ will be completed within 30 minutes 
after self-injection (ie, at Visit 1 and Visit 3). For the 1mL device cohort, the SIAQ will be 
completed within 30 minutes of completing the second injection. For the 2mL device cohort, the 
SIAQ will be completed within 30 minutes of completing the single injection. 
Version 2.0 and version 2.1 of the SIAQ are identical, except for Question 11. In version 2.0 of 
the SIAQ, Question 11 discusses the use of a plunger, while in version 2.1 of the SIAQ, 
Question 11 discusses depression of the device. Version 2.0 will therefore be used to assess 
bimekizumab-SS-1mL and bimekizumab-SS-2mL, while version 2.1 will be used to assess 
bimekizumab-AI-1mL and bimekizumab-AI-2mL. 
9.2 
Assessment of injection site pain 
A VAS will be used to assess overall injection pain due to self-injection at DV0002 Baseline and 
at 8 weeks after training. Subjects will be required to indicate their injection pain by placing a 
mark on a 100mm line from 0 (no pain) to 100 (worst possible pain).  
1mL Device Cohort 
In the 1mL device cohort of the DV0002 substudy, the 320mg bimekizumab dose will be 
administered as two 160mg sc injections with either 2 bimekizumab-SS-1mL or 2 bimekizumab-
AI-1mL devices. To evaluate injection pain for both self-injections, the VAS will be assessed 
immediately (within 15 minutes) after completion of the second self-injection. The subject will 
complete the VAS prior to completion of the post-injection SIAQ (refer to Section 9.1 for 
details). 
2mL Device Cohort 
In the 2mL device cohort, the 320mg bimekizumab dose will be administered as 1 sc injection 
with either the bimekizumab-SS-2mL or bimekizumab-AI-2mL device. To evaluate injection 
pain for the self-injection, the VAS will be assessed immediately (within 15 minutes) after 
completion of the self-injection. The subject will complete the VAS prior to completion of the 
post-injection SIAQ (refer to Section 9.1 for details).

Evaluation of post-use structural and mechanical integrity of 
self-injection investigational devices 
The visual inspection of the used devices will check for structural/mechanical integrity and 
damage (ie, clear evidence of damage/compromised structural integrity and not any superficial, 
cosmetic imperfections). All evaluations will be performed by appropriately trained site staff. 
Any device with structural/mechanical integrity issues will be returned to UCB for further 
evaluation. Superficial, cosmetic imperfections which have no impact on structural or 
mechanical integrity are to be ignored. 
Used devices that functioned as intended and which had no post-use structural or mechanical 
integrity issues (as determined by the post-use site evaluation) will also be returned to UCB for 
further evaluation.

ASSESSMENT OF PHARMACOKINETIC VARIABLES 
1mL Device Cohort 
Blood samples for measurement of trough bimekizumab PK (Section 4.1.3.2) will be collected at 
the time points specified in the schedule of study assessments (Table 5-3). 
At dosing visits, blood samples will be drawn prior to dosing (at the same time of the sampling 
for clinical laboratory tests). The time and date of collection will be recorded in the eCRF. 
Instructions pertaining to sample collection, processing, storage, labeling, and shipping are 
provided in the laboratory manual for this study. Detailed information on sample analysis will be 
provided in a bioanalytical report. 
2mL Device Cohort 
For subjects who participate in the 2mL device cohort, blood samples for measurement of trough 
bimekizumab PK levels (Section 4.1.3.2 ) will be collected at the timepoints specified in

ASSESSMENT OF SAFETY 
11.1 
Adverse events (investigational device) 
All AEs (including serious adverse events [SAEs]) will be reported in a common database for 
PS0014 and DV0002, but only ADEs, SADEs, and device deficiencies will be summarized in the 
DV0002 substudy. Specifically, only those AEs related to the use of the investigational medical 
devices (based on the Investigator’s judgement) will be assessed. All AEs (including SAEs) 
which are not assessed to be related to the investigational devices will be summarized separately 
in the report for the main study, PS0014; please refer to the PS0014 protocol for information on 
reporting and recording AEs (including SAEs). 
11.1.1 
Definitions (investigational device) 
11.1.1.1 
Adverse device effect (investigational device) 
An ADE is an AE related to the use of an investigational device. An ADE must meet 1 or more 
of the following criteria: 
 Adverse event resulting from insufficiencies or inadequacies in the IFU, the deployment, the 
implantation, the installation, the operation, or any malfunction of the investigational medical 
device.

 Adverse event that is a result of a use error or intentional misuse of the investigational 
device. 
11.1.1.1.1 
Unanticipated adverse device effect  
An unanticipated ADE is an ADE which by its nature, incidence, severity, or outcome has not 
been previously identified.  
11.1.1.2 
Serious adverse device effects  
A SADE is an ADE that has resulted in any of the consequences characteristic of an SAE. 
An SAE (and therefore a SADE) must meet 1 or more of the following criteria: 
 Death 
 Life-threatening 
(Life-threatening does not include a reaction that might have caused death had it occurred in 
a more severe form.) 
 Significant or persistent disability/incapacity 
 Congenital anomaly/birth defect (including that occurring in a fetus) 
 Important medical event that, based upon appropriate medical judgment, may jeopardize the 
patient or subject and may require medical or surgical intervention to prevent 1 of the other 
outcomes listed in the definition of serious 
(Important medical events may include, but are not limited to, potential Hy’s Law, allergic 
bronchospasm requiring intensive treatment in an emergency room or at home, blood 
dyscrasias that do not result in inpatient hospitalization, or the development of drug 
dependency or drug abuse.) 
 Initial inpatient hospitalization or prolongation of hospitalization 
(A patient admitted to a hospital, even if he/she is released on the same day, meets the 
criteria for the initial inpatient hospitalization. An emergency room visit that results in 
admission to the hospital would also qualify for the initial inpatient hospitalization criteria. 
However, emergency room visits that do not result in admission to the hospital would not 
qualify for these criteria and, instead, should be evaluated for 1 of the other criteria in the 
definition of serious [eg, life-threatening adverse experience, important medical event]. 
Hospitalizations for reasons not associated with the occurrence of an AE [eg, preplanned 
surgery or elective surgery for a pre-existing condition that has not worsened or manifested 
in an unusual or uncharacteristic manner] do not qualify for reporting. For example, if a 
subject has a condition recorded on his/her medical history and later has a preplanned surgery 
for this condition, it is not appropriate to record the surgery or hospitalization as an SAE, 
since there is no AE upon which to assess the serious criteria. Please note that, if the 
pre-existing condition has worsened or manifested in an unusual or uncharacteristic manner, 
this would then qualify as an AE and, if necessary, the seriousness of the event would need to 
be determined.)

11.1.1.2.1 
Anticipated and unanticipated serious adverse device effects 
An anticipated SADE is a SADE which by its nature, incidence, severity, or outcome has been 
identified in the risk analysis report (ISO 14155). 
An unanticipated serious adverse device effect (USADE) is a SADE which by its nature, 
incidence, severity, or outcome has not been identified in the current version of the risk analysis 
report. 
The Sponsor will determine if a SADE qualifies as an USADE. The Sponsor will also evaluate 
all SADEs to ensure that expedited reporting requirements are met according to UCB Standard 
Operating Procedures (SOPs) and applicable country-specific regulatory requirements for the 
investigational device. 
11.1.1.3 
Device deficiency (investigational device) 
A device deficiency is an inadequacy of a medical device with respect to its identity, quality, 
durability, reliability, safety, or performance. Device deficiencies include malfunctions, use 
errors, and inadequate labeling. 
11.1.2 
Procedures for reporting and recording adverse device effects and 
device deficiencies 
The subject will be given the opportunity to report ADEs, SADEs, and device deficiencies 
spontaneously. A general prompt will also be given at each study visit to detect AEs that qualify 
as ADEs, SADEs, and device deficiencies. Below is an example prompt: 
“Did you notice anything unusual about the injection?” 
11.1.2.1 
Reporting of adverse device effects 
All ADEs and SADEs will be captured on the eCRF. The eCRF will allow Investigators to 
specify whether an AE or SAE is device-related and will clarify which investigational device is 
associated with the ADE or SADE. 
An Investigator Adverse Device Effect and Device Deficiency form will be provided to the 
Investigator. The Investigator Adverse Device Effect and Device Deficiency form must be 
completed in English.  
The Investigator (or designee) shall report all SADEs and device deficiencies that might have led 
to an SAE (if suitable action had not been taken, if intervention had not been made, or if 
circumstances had been less fortunate) to UCB within 24 hours after knowledge of the event 
using the appropriate forms in the electronic data capture system. When required by national or 
local regulations, the Investigator shall also notify the IRB and regulatory agencies of all 
reportable events according to national regulations in acceptable timely conditions and may also 
be requested by the IRBs to provide annual reports. 
11.1.2.2 
Reporting of device deficiencies 
If a device deficiency related to the identity, quality, durability, reliability, safety, or performance 
of the investigational device is reported (even if the investigational device was not used), UCB 
must be informed within 1 business day (within 24 hours, as a rule) of receipt of this information 
by the site. The Investigator must forward to UCB (or designee) a duly completed Investigator

An Investigator Adverse Device Effect and Device Deficiency form will be provided to the 
Investigator. The Investigator Adverse Device Effect and Device Deficiency form must be 
completed in English. 
It is important for the Investigator, when completing the Investigator Adverse Device Effect and 
Device Deficiency form, to include an assessment and documentation of whether the device 
deficiency could have led to an SAE if any of the following occurred: 
 Suitable action had not been taken, or 
 Intervention had not been made, or 
 Circumstances had been less fortunate. 
All defective devices must be returned to UCB according to standard procedures. 
11.1.2.3 
Reporting of serious adverse device effects including device 
deficiencies with risk of serious adverse event 
If a device deficiency that could have led to an SAE (if suitable action had not been taken, or 
intervention had not been made, or circumstances had been less fortunate) is reported, UCB must 
be informed within 24 hours of receipt of this information by the site (see contact information for 
SAE reporting listed in the Serious Adverse Event Reporting section at the front of the protocol). 
The Investigator must forward to UCB (or designee) a duly completed “Investigator SAE Report 
Form for Investigational Medical Devices” provided by UCB, even if the data are incomplete, or 
if it is obvious that more data will be needed to draw any conclusions. Information recorded on 
this form will be entered into the global safety database. 
An Investigator SAE Report Form for Investigational Medical Devices will be provided to the 
Investigator. The Investigator SAE Report Form for Investigational Medical Devices must be 
completed in English.  
Additional information (eg, autopsy or laboratory reports) received by the Investigator must be 
provided within 24 hours. All documents in the local language must be accompanied by a 
translation in English, or the relevant information included in the same document must be 
summarized in the Investigator SAE Report Form for Investigational Medical Devices. 
The Investigator is specifically requested to collect and report to UCB (or designee) any ADEs 
or SADEs up to completion of the follow-up visit/telephone call for each subject, and to also 
inform participating subjects of the need to inform the Investigator of any ADEs or SADEs 
within this period. Serious AEs that the Investigator thinks may be associated with the device 
must be reported to UCB regardless of the time between the event and the end of the study. 
Upon receipt of the Investigator SAE Report Form for Investigational Medical Devices, UCB 
will perform an assessment of whether the SADE is anticipated based on the current version of 
the risk analysis report.

11.1.2.4 
Rule for repetition of an adverse device effect, serious adverse 
device effect, and/or device deficiency 
An increase in the intensity of an ADE or SADE should lead to the repetition of the ADE or 
SADE being reported with: 
 The outcome date of the first ADE or SADE that is not related to the natural course of the 
disease being the same as the start date of the repeated ADE or SADE, and the outcome of 
“worsening.” 
 The ADE or SADE verbatim term being the same for the first and repeated ADE or SADE, 
so that the repeated ADE or SADE can be easily identified as the worsening of the first one. 
11.1.3 
Follow up of adverse device effects and serious adverse device 
effects 
All ADEs and SADEs should be followed until they have resolved, have stable sequelae, the 
Investigator determines that they are no longer clinically significant, or the subject is lost to 
follow up.  
If an ADE or SADE is ongoing at the end of the study for a subject, follow up should be 
provided until resolution/stable level of sequelae is achieved, or until the Investigator no longer 
deems that it is clinically significant, or until the subject is lost to follow up. If no follow up is 
provided, the Investigator must provide a justification.  
Information on SADEs obtained after clinical database lock will be captured through the Patient 
Safety (PS) database without limitation of time. 
11.2 
Pregnancy 
All events of pregnancy or partner pregnancy will be followed and documented as described in 
the PS0014 protocol. 
11.3 
Suspected transmission of an infectious agent 
For the purposes of reporting, any suspected transmission of an infectious agent via medicinal 
products (device or IMP) should be considered as an SAE or SADE; such cases must be reported 
immediately, recorded in the Adverse Event module of the eCRF, and followed as any other 
SAE or SADE. Any organism, virus, or infectious particle (eg, prion protein transmitting 
transmissible spongiform encephalopathy), pathogenic or nonpathogenic, is considered an 
infectious agent. 
There is no evidence that there is a risk of transmission of an infectious agent with the 
investigational device. 
11.4 
Overdose of investigational medicinal product 
Excessive dosing (beyond that prescribed in the protocol and including overdose) should be 
recorded in the eCRF. Any SADE or nonserious ADE associated with excessive dosing must be 
followed as any other SADE or nonserious ADE. These events are only considered ADEs or 
SADEs if there are associated clinical signs and symptoms or if the act of taking the excess 
medicine itself is an ADE or SADE (eg, suicide attempt).

There is no evidence that there is a risk of overdose with the IMP when used with the 
investigational device. 
11.5 
Safety signal detection 
Selected data from this study will be reviewed periodically to detect, as early as possible, any 
safety concern(s) related to the IMP or the investigational device so that Investigators, clinical 
study subjects, regulatory authorities, and IRBs will be informed appropriately and as early as 
possible. 
The Study Physician (or medically qualified designee/equivalent) will conduct an ongoing 
review of SADEs and will perform ongoing SADE reconciliations in collaboration with the PS 
representative. Serious AEs not related to a device will be reported in PS0014. 
As appropriate for the stage of development and accumulated experience with the IMP and the 
investigational device, medically qualified personnel at UCB may identify additional safety 
measures (ie, vital signs) for which data will be periodically reviewed during the study. 
11.6 
Other safety measurements 
11.6.1 
Vital signs measurement 
No vital sign assessments will be performed for the DV0002 substudy. The vital sign 
assessments presented in Table 5-3, Table 5-4, and Section 8 will be captured as part of the 
PS0014 study and are described in the PS0014 protocol. 
12 
EFFICACY ASSESSMENTS FOR PS0014 
No efficacy assessments will be performed for the DV0002 substudy. The efficacy assessments 
presented in Table 5-3, Table 5-4, and Section 8 will be captured as part of the PS0014 study and 
are described in the PS0014 protocol.

STUDY MANAGEMENT AND ADMINISTRATION 
13.1 
Adherence to protocol 
The Investigator should not deviate from the DV0002 protocol or the PS0014 protocol. 
However, the Investigator should take any measure necessary, in deviation from or not defined 
by the protocol, in order to protect clinical study subjects from any immediate hazard to their 
health and safety. In this case, this action should be taken immediately, without prior notification 
of the regulatory authority, IRB, or Sponsor. 
After implementation of such measure, the Investigator must notify the Clinical Project Manager 
of the Sponsor within 24 hours and follow any local regulatory requirements. 
13.2 
Monitoring 
UCB (or designee) will monitor the study to meet the Sponsor’s monitoring SOPs, ICH-GCP 
guidelines, and applicable regulatory requirements, and to ensure that study initiation, conduct, 
and closure are adequate. Monitoring of the study may be delegated by UCB to a contract 
research organization (CRO) or a contract monitor. 
The Investigator and his/her staff are expected to cooperate with UCB (or designee) and to be 
available during the monitoring visits to answer questions sufficiently and to provide any

missing information. The Investigator(s)/institution(s) will permit direct access to source 
data/documents for study-related monitoring, audits, IRB review, and regulatory inspection(s). 
The Investigator will allow UCB (or designee) to periodically review all eCRFs and 
corresponding source documents (eg, hospital and laboratory records for each study participant). 
Monitoring visits will provide UCB (or designee) with the opportunity to evaluate the progress 
of the study, verify the accuracy and completeness of eCRFs, ensure that all protocol 
requirements, applicable authorities’ regulations, and Investigator’s obligations are being 
fulfilled, and resolve any inconsistencies in the study records. 
13.2.1 
Definition of source data  
All source documents must be accurate, clear, unambiguous, permanent, and capable of being 
audited. They should be made using some permanent form of recording (ink, typing, printing, 
optical disc). They should not be obscured by correction fluid or have temporary attachments 
(such as removable self-stick notes).  
Source documents are original records in which raw data are first recorded. These may include 
hospital/clinic/general practitioner records, charts, diaries, x-rays, laboratory results, printouts, 
pharmacy records, care records, ECG or other printouts, completed scales, or quality of life 
questionnaires, for example. Source documents should be kept in a secure, limited access area. 
Source documents that are computer generated and stored electronically must be printed for 
review by the monitor (eg, ECG reports). Once printed, these copies should be signed and dated 
by the Investigator and become a permanent part of the subject’s source documents. The 
Investigator will facilitate the process for enabling the monitor to compare the content of the 
printout and the data stored in the computer to ensure all data are consistent. 
Electronic data records, such as Holter monitor records or electroencephalogram records, must 
be saved and stored as instructed by UCB (or designee). 
13.2.2 
Source data verification 
Source data verification ensures accuracy and credibility of the data obtained. During monitoring 
visits, reported data are reviewed with regard to being accurate, complete, and verifiable from 
source documents (eg, subject files, recordings from automated instruments, tracings [ECG], 
x-ray films, laboratory notes). All data reported on the eCRF should be supported by source 
documents, unless otherwise specified in Section 13.2.1. 
13.3 
Data handling 
13.3.1 
Case Report form completion 
This study is performed using remote data capture; the same data capture is used for PS0014 and 
DV0002. The Investigator is responsible for prompt reporting of accurate, complete, and legible 
data in the eCRFs and in all required reports.  
Any change or correction to the eCRF after saving must be accompanied by a reason for the 
change. 
Corrections made after the Investigator’s review and approval (by means of a 
password/electronic signature) will be reapproved by the Investigator. 
The Investigator should maintain a list of personnel authorized to enter data into the eCRF.

Detailed instructions will be provided in the eCRF Completion Guidelines. 
13.3.2 
Database entry and reconciliation 
Case Report forms/external electronic data will be entered/loaded into a validated electronic 
database using a clinical data management system (CDMS). Computerized data cleaning checks 
will be used, in addition to manual review, to check for discrepancies and to ensure consistency 
of the data. The data are entered into the eCRFs once and are subsequently verified. 
An electronic audit trail system will be maintained within the CDMS to track all data changes in 
the database once the data have been saved initially into the system or electronically loaded. 
Regular backups of the electronic data will be performed. 
13.3.3 
Subject Screening and Enrollment log/Subject Identification Code list 
The subject’s screening and enrollment will be recorded in the Subject Screening and 
Enrollment log. 
The Investigator will keep a Subject Identification Code list. This list will remain with the 
Investigator and be used for unambiguous identification of each subject. 
The subject’s consent and enrollment in the study must be recorded in the subject’s medical 
record. These data should identify the study and document the dates of the subject’s 
participation. 
13.4 
Termination of the study 
UCB reserves the right to temporarily suspend or prematurely discontinue this study either at a 
single site, multiple sites, or at all sites at any time for reasons including, but not limited to, 
safety or ethical issues, inaccurate or incomplete data recording, noncompliance, or 
unsatisfactory enrollment with respect to quality or quantity. 
The study may also be temporarily suspended or prematurely terminated in either of the 
following situations: 
 Severe or serious injection site reaction (eg, bleeding, bruising, pain) that, in the opinion of 
the Investigator, the overseeing IRB, or the Sponsor, is likely to be seen in other enrolled 
subjects who have not yet been injected with bimekizumab. 
 Unexpected device malfunction leading to a failed or incomplete injection, or resulting in an 
SAE that, in the opinion of the Investigator, the overseeing IRB, or the Sponsor, is likely to 
be seen in other enrolled subjects who have not yet been injected with bimekizumab. 
If the study is prematurely terminated or suspended, UCB (or designee) will inform the 
Investigators/institutions and the regulatory authority(ies) of the termination or suspension and 
the reason(s) for the termination or suspension, in accordance with applicable regulatory 
requirement(s). The IRB should also be informed and provided with reason(s) for the termination 
or suspension by the Sponsor or by the Investigator/institution, as specified by the applicable 
regulatory requirement(s). In addition, arrangements will be made for the return of all unused 
IMP and other material in accordance with UCB procedures for the study.

Archiving and data retention 
The Investigator will maintain adequate records for the study, including eCRFs, medical records, 
laboratory results, informed consent documents, drug dispensing and disposition records, safety 
reports, information regarding participants who discontinued, and other pertinent data. 
All essential documents are to be retained by the Investigator until at least 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 or investigational device. These 
documents should be retained for a longer period; however, if required by the applicable 
regulatory requirement(s) or by an agreement with UCB (CPMP/ICH/135/95, 2002 
[Section 4.9.5]). The Investigator will contact UCB for authorization prior to the destruction of 
any study records or in the event of accidental loss or destruction of any study records. The 
Investigator will also notify UCB should he/she relocate or move the study-related files to a 
location other than that specified in the Sponsor’s trial master file. 
13.6 
Audit and inspection 
The Investigator will permit study-related audits mandated by UCB, after reasonable notice, and 
inspections by domestic or foreign regulatory authorities. 
The main purposes of an audit or inspection are to confirm that the rights and well-being of the 
subjects enrolled have been protected, that enrolled subjects (ie, signing consent and undergoing 
study procedures) are appropriate for the study, and that all data relevant for the evaluation of the 
IMP and the investigational device have been processed and reported in compliance with the 
planned arrangements, the protocol, investigational site, and IRB SOPs, ICH GCP, and 
applicable regulatory requirements. 
The Investigator will provide direct access to all study documents, source records, and source 
data. If an inspection by a regulatory authority is announced, the Investigator will immediately 
inform UCB (or designee). 
13.7 
Good Clinical Practice 
Noncompliance with the protocol, ICH-GCP, or local regulatory requirements by the 
Investigator, institution, institution staff, or designees of the Sponsor will lead to prompt action 
by UCB to secure compliance. Continued noncompliance may result in the termination of the 
site’s involvement in the study.

STATISTICS 
A description of statistical methods follows and will be described in more detail in the Statistical 
Analysis Plan (SAP). 
Once subjects in the 1mL device cohort complete DV0002, a final analysis for that cohort will be 
performed, and a clinical study report will be prepared. A separate final analysis will be

14.1 
Definition of analysis sets 
1mL Device Cohort  
For the 1mL device cohort, 2 different Safety Sets (SS) will be generated (1 for each device 
type): the bimekizumab-SS-1mL Safety Set (SS-s) and the bimekizumab-AI-1mL Safety Set 
(SS-a). Each SS will consist of all subjects in the study who receive at least 1 dose of 
bimekizumab by the indicated self-injection investigational device. Safety variables will be 
analyzed using the SS-s and SS-a. 
Two different Full Analysis Sets (FASs) will be generated (1 for each device type): the 
bimekizumab-SS-1mL Full Analysis Set (FAS-s) and the bimekizumab-AI-1mL Full Analysis 
Set (FAS-a). Each FAS will consist of all subjects in the SS-s or SS-a who self-inject at least 
1 dose of bimekizumab using the given device and who have an assessment of self-injection. All 
self-injection related endpoints will be analyzed using the FAS-s and FAS-a. 
For the PK analyses, 2 different Pharmacokinetic Per Protocol Sets (PK-PPS) will be generated 
(1 for each device type): the bimekizumab-SS-1mL PK-PPS (PK-PPS-s) and the 
bimekizumab-AI-1mL PK-PPS (PK-PPS-a). Each PK-PPS will consist of all subjects who 
receive the same bimekizumab administration (frequency and dose) in the PS0014 feeder studies 
as in the DV0002 substudy and who have at least 1 evaluable PK assessment in the DV0002 
substudy without important protocol deviations that would affect the concentration. 
Pharmacokinetic variables will be analyzed using the PK-PPS-s and PK-PPS-a. 
All PK assessments after baseline assessments from feeder study will be considered for the 
requirement of at least 1 evaluable PK assessment.  
2mL Device Cohort  
For the 2mL device cohort, the same analysis sets will be generated. 
14.2 
General statistical considerations 
This is an estimation study design with no formal statistical hypothesis testing. The study will 
estimate the true population proportion and/or mean of self-injection related endpoints for each 
device separately. Summary statistics for continuous variables will include: number of available 
observations, mean, standard deviation, minimum, median, and maximum. For categorical 
variables, the number and proportion of subjects, along with the 90% confidence interval (CI) 
based on the Exact Binomial method, will be presented. 
The Baseline value is defined as the last nonmissing measurement prior to the first self-injection 
at DV0002 Visit 1 (Baseline). No imputation of missing data will be performed. All data 
recorded in the eCRF and questionnaires will be listed. 
14.3 
Planned analyses of outcome variables 
All statistical analyses will be descriptive in nature. No inferential statistical analyses are 
planned.  
All analyses will be performed separately for the 1mL device cohort and for the 2mL device 
cohort. Once subjects in the 1mL device cohort complete DV0002, a final analysis will be 
performed for that cohort, and a clinical study report will be prepared. A separate final analysis

will be performed for the 2mL device cohort once all data have been collected and will be 
reported separately from the initial clinical study report. 
14.3.1 
Analysis of the primary outcome variable 
The primary outcome variable is the percentage of all subjects able to self-administer safe and 
effective injections using the given device at DV0002 Week 8 (8 weeks after training). Safe and 
effective self-injection will be evaluated by the study personnel as defined in in Section 4.1.1. 
The number and percentage of subjects with safe and effective self-injections will be tabulated 
separately for each device overall and within each device by dosing regimen using the relevant 
FAS population (FAS-s or FAS-a). The 90% CIs based on the Exact Binomial method will be 
reported as well. 
14.3.2 
Analysis of the secondary outcome variable 
The secondary outcome variable is the percentage of subjects able to self-administer safe and 
effective injections using the given device at DV0002 Baseline (first self-injection visit). Safe 
and effective self-injection will be evaluated by the study personnel as defined in Section 4.1.1. 
The secondary outcome variables will be analyzed in the same manner as the primary outcome 
variable (see Section 14.3.1). 
14.3.3 
Analysis of other outcome variables 
The other outcome variables are defined in Section 4.1.3. These variables will be summarized 
using descriptive statistics and they will be tabulated separately for each device overall and 
within each device by dosing regimen using the relevant FAS population (FAS-s or FAS-a). 
14.4 
Planned pharmacokinetic analyses 
The statistical analyses of the PK data will be descriptive in nature and will be summarized using 
the relevant device-specific population (PK-PPS-s or PK-PPS-a). Data will be analyzed overall 
for each device by injection type (self-administered or study personnel-administered), by 
injection site (abdomen or thigh), and by BMI category. Three BMI categories will be defined 
based on tertiles derived from subjects’ Baseline BMI values within the device-specific 
population (PK-PPS-s or PK-PPS-a). 
To allow for an analysis of PK trough levels for bimekizumab administration via self-injection or 
via study personnel administration, pre-dose PK samples will be taken throughout the DV0002 
substudy. For the Q4W dose regimen, PK trough levels will be determined based on pre-dose PK 
sampling at DV0002 Baseline and Week 8 for the study personnel administration and at DV0002 
Week 4 and Week 12 for the self-administration trough levels, respectively. For the Q8W dose 
regimen, PK trough levels will be determined based on pre-dose PK sampling at DV0002 
Baseline for the study personnel administration and at 8 weeks after training (DV0002 Week 8) 
and DV0002 Week 16 for the self-administration trough levels, respectively. For the analysis of 
PK trough levels by injection site (abdomen or thigh) and by BMI category (by tertile), only 
self-administration PK trough levels will be used.

14.5 
Planned safety analyses 
The safety variable is the occurrence of ADEs; additional safety and tolerability variables will be 
collected in PS0014 (see Section 4.1.3.3). Analyses of safety data will be done separately for 
each device overall and within each device by dosing regimen using the relevant SS population 
(SS-s or SS-a). 
All ADE data will be listed and no statistical testing will be performed. Only treatment-emergent 
ADEs will be included in the summary tables. All ADEs will be coded and classified by system 
organ class, high level term, and preferred term according to the latest version of the Medical 
Dictionary for Regulatory Activities. Adverse device effects will be summarized by the 
frequency and percentage of subjects having 1 or more of the events in question. Additional 
planned summaries include overall ADEs and SADEs. 
14.6 
Planned efficacy analyses 
No efficacy analyses are planned for the DV0002 substudy. 
14.7 
Handling of protocol deviations 
Only subjects who had no important protocol deviations affecting the primary outcome variable, 
as confirmed during ongoing data cleaning meetings prior to database lock, will be included in 
the FAS-s or FAS-a. Important protocol deviations are deviations from the protocol which could 
potentially have a meaningful impact on the primary objective of the study. The criteria for 
identifying important protocol deviations and the classification of important protocol deviations 
will be defined within the project Data Cleaning Plan. To the extent feasible, the rules for 
identifying protocol deviations will be defined without review of the data and without 
consideration of the frequency of occurrence of such deviations. Whenever possible, criteria for 
identifying important protocol deviations will be implemented algorithmically to ensure 
consistency in the classification of important protocol deviations across all subjects. 
14.8 
Handling of dropouts or missing data 
There will be no special procedures for handling missing data. All imputation of missing or 
partial dates for safety assessments will be detailed in the SAP. 
14.9 
Planned interim analysis and data monitoring 
No interim analysis is planned for the DV0002 study. No Data Monitoring Committee will be 
established for this study.  
The subjects of DV0002 are ongoing subjects of PS0014. Data cut off for the 1mL final analysis 
will be last subject last Week 16 visit in DV0002 in the 1mL device cohort. Data cut off for the 
2mL final analysis will be last subject last Week 16 visit in DV0002 in the 2mL device cohort. 
Data cut off rules will be applied for ongoing ADEs and ongoing concomitant medication.

1mL Device Cohort  
For the 1mL device cohort, to maintain blinding in the PS0014 feeder studies, DV0002 will 
recruit subjects who were administered bimekizumab 320mg (Q4W or Q8W) and subjects who 
were administered placebo or ustekinumab in the PS0014 feeder studies. A total of 100 subjects 
(50 subjects per device arm) are planned for PK trough level analyses, but these analyses can 
only be performed on subjects who do not change their bimekizumab dose or dosing regimen 
(ie, 320mg bimekizumab Q4W or Q8W) between the PS0014 feeder studies and in the DV0002 
substudy. The DV0002 substudy will therefore enroll approximately 200 subjects (to compensate 
for subjects with bimekizumab dose changes) to ensure that 100 subjects are available for PK 
trough analysis.  
Subjects who enroll in the DV0002 substudy 1mL device cohort will be randomly assigned to 
the bimekizumab-SS-1mL or the bimekizumab-AI-1mL device arms (each device arm will 
consist of approximately 100 subjects). Within each device arm, subjects will be divided into 
tertiles by BMI; there will be approximately 33 subjects per tertile, which is expected to yield 
approximately 16 to 17 subjects per tertile who are evaluable for steady state trough PK level 
analyses. 
2mL Device Cohort  
Once the 1mL device cohort has finished enrolling, the 2mL device cohort will start enrolling. 
Subjects who participated in the 1mL device cohort of DV0002 are not eligible to enroll in the 
2mL device cohort. For evaluation of the 2mL device, it is planned to enroll approximately 
100 subjects. All 100 subjects will have been on a consistent bimekizumab dose regimen for at 
least 16 weeks, and thus all will be evaluable for the PK trough level analyses. 
Subjects who enroll in the DV0002 substudy 2mL device cohort will be randomly assigned to 
the bimekizumab-SS-2mL or the bimekizumab-AI-2mL device arms (each device arm will 
consist of approximately 50 subjects). Within each device arm, subjects will be divided into 
tertiles by BMI; there will be approximately 16 to 17 subjects per tertile who are evaluable for 
steady state trough PK level analyses.

The subject may withdraw his/her consent to participate in the study at any time. A subject is 
considered as enrolled in the study when he/she has signed the ICF. An eCRF must not be 
started, nor may any study-specific procedure be performed for a given subject, without having 
obtained his/her written consent to participate in the study. 
15.2 
Subject identification cards 
Upon signing the ICF, the subject or legal representative will be provided with a subject 
identification card in the language of the subject. The Investigator will fill in the subject 
identifying information and medical emergency contact information. The Investigator will 
instruct the subject to keep the card with him/her at all times. 
15.3 
Institutional Review Boards  
The study will be conducted under the auspices of an IRB, as defined in local regulations, 
ICH-GCP, and in accordance with the ethical principles that have their origin in the Declaration 
of Helsinki. 
The Investigator/UCB will ensure that an appropriately constituted IRB, that complies with the 
requirements of the current ICH-GCP version or applicable country-specific regulations, will be 
responsible for the initial and continuing review and approval of the clinical study. Prior to 
initiation of the study, the Investigator/UCB will forward copies of the protocol, ICF, 
Investigator’s Brochure, Investigator’s curriculum vitae (if applicable), advertisement (if 
applicable), and all other subject-related documents to be used for the study to the IRB for its 
review and approval. 
Before initiating a study, the Investigator will have written and dated full approval from the 
responsible IRB for the protocol. 
The Investigator will also promptly report to the IRB all changes in the study, all unanticipated 
problems involving risks to human subjects or others, and any protocol deviations, to eliminate 
immediate hazards to subjects. 
The Investigator will not make any changes in the study or study conduct without IRB approval, 
except where necessary to eliminate apparent immediate hazards to the subjects. For minor 
changes to a previously approved protocol during the period covered by the original approval, it 
may be possible for the Investigator to obtain an expedited review by the IRB as allowed. 
As part of the IRB requirements for continuing review of approved studies, the Investigator will 
be responsible for submitting periodic progress reports to the IRB (based on IRB requirements), 
at intervals appropriate to the degree of subject risk involved, but no less than once per year. The 
Investigator should provide a final report to the IRB following study completion.

APPENDICES 
18.1 
Protocol Amendment 1 
Rationale for the amendment 
This protocol has been amended to add the evaluation of the 2mL self-injection devices 
developed by UCB: a 2mL bimekizumab safety syringe (bimekizumab‑SS‑2mL) and a 
2mL bimekizumab auto‑injector (bimekizumab‑AI‑2mL).  
Modifications and changes 
Global changes: 
The following changes were made throughout the protocol:  
 The DV0002 study number was added before the study visit where it was necessary to 
distinguish it from the PS0014 study visits. 
 The list of abbreviations was updated accordingly. 
 Minor spelling, editorial, and formatting changes were made throughout the document.  
Specific changes: 
Change #1  
Section 1 Summary 
DV0002 is a multicenter, open-label, randomized substudy in adult subjects with moderate to 
severe chronic plaque psoriasis (PSO) to evaluate the safe and effective use of 2 single-use 
disposable self-injecting investigational devices for the subcutaneous (sc) administration of 
bimekizumab solution (the investigational medicinal product [IMP]). It is expected that 
individuals with PSO will prefer to have options for the self-administration of bimekizumab. 
DV0002 will therefore evaluate 2 different self-injection investigational devices: the 1mL 
bimekizumab safety syringe (bimekizumab-SS-1mL) and the 1mL bimekizumab auto-injector 
(bimekizumab-AI-1mL). 
DV0002 is a substudy of PS0014, which is a multicenter, open-label, long-term safety study for 
subjects with moderate to severe chronic plaque PSO who complete 1 of the Phase 3 feeder 
studies (PS0008, PS0009, or PS0013). The PS0014 study will evaluate the long-term safety, 
tolerability, and efficacy of bimekizumab in subjects with PSO, and study personnel qualified in 
sc injection technique will administer bimekizumab to subjects in a 1mL True North prefilled 
syringe (referred to throughout this protocol as the 1mL PFS). Subjects will begin the DV0002 
substudy and the PS0014 study at the same time. The DV0002 substudy will include all PS0014 
study assessments from Baseline to Week 16 (inclusive). However, subjects in the DV0002 
substudy will self-administer bimekizumab at Baseline and at Week 8. Subjects will be randomly 
assigned to either the bimekizumab-SS-1mL or the bimekizumab-AI-1mL device arm.  
During the 16-week Treatment Period of DV0002, subjects will receive either bimekizumab 
320mg every 8 weeks (Q8W) or bimekizumab 320mg every 4 weeks (Q4W), based on their 
assigned dosing at Baseline. This dose regimen will remain stable for the entire 16-week 
Treatment Period of DV0002. In the DV0002 substudy, subjects will be assigned to 1 of the 
2 self-injection investigational devices and will self-administer bimekizumab only at Baseline

and at Week 8, regardless of their assigned dosing regimen. For subjects in the bimekizumab 
Q4W dosing arm, bimekizumab will be administered by study personnel at Week 4 and 
Week 12; for all subjects, bimekizumab will be administered by study personnel at Week 16. A 
safety follow-up (SFU) telephone call will occur 1 week after the last self-administration (at 
Week 9). After Week 16 in the DV0002 substudy, subjects will continue in PS0014 (the next 
visit after DV0002 completion will be the Week 20 Visit in PS0014). 
To compensate for subjects who have different study treatments between the feeder studies and 
DV0002, DV0002 is planned to enroll approximately 200 subjects (100 subjects per device arm) 
to ensure that approximately 50 subjects per device arm are evaluable for steady state trough 
pharmacokinetic (PK) level analyses. Within each device arm, subjects will be divided into 
tertiles by body mass index (BMI); there will be approximately 33 subjects per tertile, which is 
expected to yield approximately 16 to 17 subjects per tertile who are evaluable for steady state 
trough PK level analyses.  
The primary objective of the DV0002 substudy is to evaluate for each device the ability of 
subjects with moderate to severe chronic plaque PSO to safely and effectively self-inject 
bimekizumab 8 weeks after training in the self-injection technique using the 
bimekizumab-SS-1mL or the bimekizumab-AI-1mL. The primary outcome variable is the 
percentage of subjects able to self-administer safe and effective injections using the 
bimekizumab-SS-1mL or the bimekizumab-AI-1mL, respectively, at Week 8.  
Safe and effective self-injection will be evaluated by the study personnel and is defined as: 
 Complete dose delivery: Subject self-injects the complete dose of bimekizumab as confirmed 
by a visual inspection of the bimekizumab-SS-1mL or the bimekizumab-AI-1mL, which 
shows that the IMP is delivered completely (ie, container is empty), and 
 No adverse device effects (ADEs) that would preclude continued use of the device for 
self-injection (ie, no serious ADEs [SADEs] and/or ADEs leading to withdrawal from the 
DV0002 substudy) 
In the DV0002 substudy, the 320mg bimekizumab dose will be administered as two 160mg 
injections with either 2 bimekizumab-SS-1mL devices or 2 bimekizumab-AI-1mL devices. Each 
self-injection will be evaluated by study personnel for safety and effectiveness using the above 
criteria. The endpoint of safe and effective self-injection will be met only if both self-injections 
are determined to be safe and effective. 
The secondary study objectives and other study objectives are provided in Section 3.2 and 
Section 3.3, respectively. Of note, one of the other study objectives is to assess trough PK levels 
associated with self-injection using the test device, injection by study personnel using the 1mL 
PFS, injection site (abdomen or thigh), and BMI category (by tertile). The secondary outcome 
variable, other outcome variables, and the other safety variable are listed in Section 4.1.2, 
Section 4.1.3, and Section 4.1.3.3, respectively.

bimekizumab solution (the investigational medicinal product [IMP]). It is expected that 
individuals with PSO will prefer to have options for the self-administration of bimekizumab. 
DV0002 will therefore evaluate 2 different self-injection investigational devices: the 1mL 
bimekizumab safety syringe (bimekizumab-SS-1mL) and the 1mL bimekizumab auto-injector 
(bimekizumab-AI-1mL). The 4 self-injection devices to be tested are the 1mL bimekizumab 
safety syringe (bimekizumab-SS-1mL), the 1mL bimekizumab auto injector 
(bimekizumab-AI-1mL), the 2mL bimekizumab safety syringe (bimekizumab-SS-2mL), 
and the 2mL bimekizumab auto injector (bimekizumab-AI-2ml). 
DV0002 is a substudy of PS0014, which is a multicenter, open-label, long-term safety study for 
subjects with moderate to severe chronic plaque PSO who complete 1 of the Phase 3 feeder 
studies (PS0008, PS0009, or PS0013). The PS0014 study will evaluate the long-term safety, 
tolerability, and efficacy of bimekizumab in subjects with PSO, and study personnel qualified in 
sc injection technique will administer bimekizumab to subjects in a 1mL True North prefilled 
syringe (referred to throughout this protocol as the 1mL PFS). Subjects will begin the DV0002 
substudy and the PS0014 study at the same time. The DV0002 substudy will include all PS0014 
study assessments from Baseline to Week 16 (inclusive). However, subjects In the DV0002 
substudy, subjects will self-administer bimekizumab at DV0002 Baseline and at DV0002 
Week 8. Subjects will be randomly assigned to either the bimekizumab-SS-1mL or the 
bimekizumab-AI-1mL device arm. 
During the 16-week Treatment Period of DV0002, subjects will receive either bimekizumab 
320mg every 8 weeks (Q8W) or bimekizumab 320mg every 4 weeks (Q4W), based on their 
assigned dosing at Baseline of PS0014. The same interactive response technology (IRT) will 
be used for both studies (DV0002 and PS0014). The dose regimen will remain stable for the 
entire Treatment Period of DV0002.  
In the DV0002 substudy, subjects will be assigned to 1 of the 24 self-injection investigational 
devices and will self-administer bimekizumab only at DV0002 Baseline and at DV0002 Week 8 
after training, regardless of their assigned dosing regimen. For subjects in the bimekizumab 
Q4W dosing arm, bimekizumab will be administered by study personnel at Week 4 and 
Week 12; for all subjects, bimekizumab will be administered by study personnel at Week 16. 
Bimekizumab will be administered by study personnel at DV0002 Week 4 and DV0002 
Week 12 for subjects in the Q4W dosing arm and at DV0002 Week 16 for both dosing 
arms. A safety follow-up (SFU) telephone call will occur 1 week after the last 
self-administration (at DV0002 Week 9). After Week 16 in the DV0002 substudy, subjects will 
continue in PS0014 (the next visit after DV0002 completion will be the Week 20 Visit in 
PS0014).

the bimekizumab-SS-1mL or the bimekizumab-AI-1mL (see Section 7.10). Regardless of the 
assigned dose regimen, subjects will perform self-injection with the assigned device only at 
Baseline (corresponding to the Baseline Visit of PS0014) and at Week 8 (corresponding to 
Week 8 of PS0014).

same manner (eg, both self-administered injections or both study personnel-administered injections), but each 
injection will be administered at a separate injection site and rotation between injection sites should be 
observed. 
Note: Visits in the DV0002 substudy correlate with the same visit in the PS0014 study (ie, the DV0002 Baseline 
Visit is the PS0014 Baseline Visit). Dose regimen will be assigned at Baseline, and the same interactive 
response technology will be used for both studies 
The bimekizumab administration schedule optimizes the collection of PK trough data within the 
constraints of a short treatment period and a Q4W and Q8W dosing regimen. At Weeks 4 and 12, 
subjects on the Q4W dosing regimen will be injected by study personnel with two injections 
each of 160 mg bimekizumab using a 1mL PFS (i.e., the same device as that used in PS0014).

DV0002 is a Phase 3 open-label, randomized, noncomparator, North America-only substudy to 
PS0014. PS0014 will evaluate the long-term safety, tolerability, and efficacy of bimekizumab in 
subjects with moderate to severe chronic plaque PSO, and study personnel will administer 
bimekizumab to subjects in a 1mL PFS. In the DV0002 substudy, the safe and effective use of 
the bimekizumab-SS-1mL, bimekizumab-AI-1mL, bimekizumab-SS-2mL, or the 
bimekizumab-AI-2mL for the sc self-injection of bimekizumab solution by subjects with PSO 
will be evaluated.  
Subjects from selected sites in the PS0014 feeder studies PS0008, PS0009, and PS0013 will be 
eligible for the DV0002 substudy. The DV0002 substudy will maintain all study assessments of 
the main PS0014 study from Baseline to Week 16 (inclusive). However, only subjects in the 
DV0002 substudy will self-administer bimekizumab. At DV0002 Baseline, each subject will be 
provided with training in self-injection and will receive the instructions for use (IFU) and any 
other applicable training materials.  
1mL Device Cohort 
For the 1mL device cohort, subjects in the DV0002 substudy will perform self-injections at 
Baseline (corresponding to the Baseline Visit of PS0014) with a subsequent self-injection at 
Week 8 (corresponding to Week 8 of PS0014).  
During the 16-week Treatment Period of DV0002, subjects will receive either bimekizumab 
320mg Q8W or bimekizumab 320mg Q4W, based on their assigned dosing at Baseline 
(Table 5-1). Baseline for DV0002 and Baseline for PS0014 will occur at the same time, and the 
same interactive response technology (IRT) will be used for both studies. The 320mg 
bimekizumab dose will be administered as two 160mg injections, and both injections will be 
either self-administered using the testinvestigational device (at Baseline and Week 8) or 
administered by study personnel using the 1mL PFS (at Week 4 and Week 12 for subjects in the 
Q4W dosing arm and at Week 16 for both dosing arms). This dose regimen will remain stable for 
the entire 16-week Treatment Period of DV0002, as per PS0014 design. The DV0002 substudy 
will evaluate 2 self-injection investigational devices: the bimekizumab-SS-1mL and the 
bimekizumab-AI-1mL.  
Eligible subjects (PS0014 entry criteria and Section 6 DV0002 entry criteria) will be 
randomly assigned in a 1:1 ratio to perform self-injection using either the bimekizumab-SS-1mL 
or the bimekizumab-AI-1mL (see Section 7.10). Regardless of the assigned dose regimen, 
subjects will perform self-injection with the assigned device only at Baseline (corresponding to 
the Baseline Visit of PS0014) and at Week 8 (corresponding to Week 8 of PS0014).

Section 5.1 
Study description, Addition of 2mL device cohort 
The following text was added at the end of Section 5.1 and appears before Section 5.1.1: 
2mL Device Cohort 
To allow flexible enrollment, subjects may be randomized in the 2mL device cohort at the 
PS0014 Week 24, Week 28, or Week 32 visit for subjects receiving bimekizumab Q4W or 
the PS0014 Week 24 or Week 32 visit for subjects receiving bimekizumab Q8W.  
For the 2mL device cohort, subjects will perform self-injections at DV0002 Baseline with a 
subsequent self-injection 8 weeks after training. The 2mL device cohort will evaluate 
2 self-injection devices: the bimekizumab-SS-2mL and the bimekizumab-AI-2mL. 
During the Treatment Period of DV0002, subjects will receive either bimekizumab 320mg 
Q8W or bimekizumab 320mg Q4W, based on their assigned dosing at Baseline of 
PS0014 (Table 5-3). In the 2mL device cohort, Baseline for DV0002 will occur at the 
PS0014 Week 24, Week 28, or Week 32 visit for subjects receiving bimekizumab Q4W or 
the PS0014 Week 24 or Week 32 visit for subjects receiving bimekizumab Q8W. The same 
IRT will be used for both studies. The 320mg bimekizumab dose will either be self-
administered as 1 injection using the assigned investigational device (at DV0002 Baseline 
and Week 8) or administered as 2 injections by study personnel using the 1mL PFS (at 
DV0002 Week 4 and Week 12 for subjects in the Q4W dosing arm and at DV0002 Week 16

associated with injection by: 
 Study personnel using the 1mL PFS from PK samples collected (before self-injection) 
at DV0002 Baseline (ie, PK data from 1 timepoint) 
 Subject self-injection using the assigned device from PK samples collected (before 
self-injection) at DV0002 Week 8 and (before injection by study personnel) at 
DV0002 Week 16 (ie, PK data from 2 timepoints) 
In addition to self-injections, DV0002 substudy-specific assessments (eg, study personnel 
evaluation, SIAQ responses, VAS for injection site pain, and PK analyses; see Section 5.2) 
will be performed from DV0002 Baseline through Week 16 (inclusive). An SFU telephone 
call will occur 1 week after the last self-administration (at DV0002 Week 9).  
After Week 16 in the DV0002 substudy, subjects will continue in PS0014. Studies DV0002 
and PS0014 will share a common database/eCRF system (including common AE reporting) 
and a common IRT. 
Subjects who are withdrawn from DV0002 but continue their PS0014 study participation 
will be required to perform an SFU telephone call 1 week after their final DV0002 dosing 
visit (see Section 6.3). Subjects who are withdrawn from bimekizumab treatment (PS0014 
study) during the course of DV0002 will also be required to follow the PS0014 withdrawal 
procedures.

Rationale for study design and selection of dose, paragraph 2 
It is expected that most individuals who will use commercial bimekizumab for the treatment of 
moderate to severe chronic plaque PSO will self-inject bimekizumab and also that these 
individuals will prefer to have options for the self-administration of their medication. DV0002 
will therefore evaluate the safe and effective use of 2 different self-injection investigational 
devices: bimekizumab-SS-1mL and bimekizumab-AI-1mL. In addition, DV0002 will assess 
trough PK levels associated with self-injection using the test device, injection by study personnel 
using the 1mL PFS, injection site (abdomen or thigh), and BMI category (by tertile).

Instruction for use of bimekizumab-SS-2mL 
The bimekizumab-SS-2mL is used to administer a sc injection in either the right or left 
lateral abdominal wall or the right or left outer thigh without massage. Treatment of the 
injection site with an anesthetic cream prior to dosing is not permitted. 
During the study (at DV0002 Baseline and Week 8), 1 bimekizumab-SS-2mL device will be 
used to administer a 320mg injection of bimekizumab. To use the bimekizumab-SS-2mL, 
the rigid needle shield (RNS) is removed, and the plunger rod is fully depressed, which 
empties the syringe contents through the needle. When the plunger rod reaches its final 
position the needle safety retraction mechanism is activated, which retracts the sleeve, 
syringe, and plunger rod and holds the needle safely within the body molding.  
Additional instructions for device use, including the injection angle, are provided in the

Treatment to be administered 
The IMP used in this study is bimekizumab. Bimekizumab will be supplied at a concentration of 
160mg/mL (55mM sodium acetate, 220mM glycine, 0.04% polysorbate 80 at pH 5.0) for sc 
injection in the bimekizumab-SS-1mL or the bimekizumab-AI-1mL. 
The IMP will be administered according to the schedule shown in Table 5-1. Subjects will be 
assigned to the use of 1 device and will receive the following doses of IMP based on their 
established dosing regimen in PS0014: 
 320mg bimekizumab, Q8W or 
 320mg bimekizumab, Q4W. 
Regardless of the assigned dose regimen, subjects will perform self-injection with the assigned 
device only at Baseline and at Week 8. The 320mg bimekizumab dose will be administered as 
two 160mg injections with either 2 bimekizumab-SS-1mL or 2 bimekizumab-AI-1mL devices.

Assessment of self-injection experience by SIAQ, paragraph 2 and 3 
The SIAQ was developed by UCB to assess the perceived advantages and the potential 
limitations of self-injection of an sc medication (Keininger and Coteur, 2011). The pre-injection 
SIAQ is composed of 7 items grouped into 3 domains (feelings about injection, self-confidence, 
and satisfaction with the current mode of administration). The post-injection SIAQ is composed 
of 21 items grouped into 6 domains (feelings about injection, self-image, self-confidence, 
injection site reactions, ease of use, and satisfaction with self-injection). The pre-injection SIAQ 
will be completed at Visit 1, and the post-injection SIAQ will be completed within 30 minutes 
after each self-injection (ie, at Visit 1 and Visit 3).  
Version 2.0 and version 2.1 of the SIAQ are identical, except for Question 11. In version 2.0 of 
the SIAQ, Question 11 discusses the use of a plunger, while in version 2.1 of the SIAQ, Question

11 discusses depression of the device. Version 2.0 will therefore be used to assess 
bimekizumab-SS-1mL and bimekizumab-SS-2mL, while version 2.1 will be used to assess 
bimekizumab-AI-1mL and bimekizumab-AI-2mL.

Section 9.2 
Assessment of injection site pain 
A VAS will be used to assess overall injection pain due to self-injection at Baseline and at 
Week 8. Subjects will be required to indicate their injection pain by placing a mark on a 100mm 
line from 0 (no pain) to 100 (worst possible pain). In the DV0002 substudy, the 320mg 
bimekizumab dose will be administered as two 160mg sc injections with either 
2 bimekizumab-SS-1mL or 2 bimekizumab-AI-1mL devices. To evaluate injection pain for both 
self-injections, the VAS will be assessed immediately (within 15 minutes) after completion of 
the second self-injection. The subject will complete the VAS prior to completion of the 
post-injection SIAQ (refer to Section 9.1 for details).

(abdomen or thigh), and by BMI category. Three BMI categories will be defined based on 
tertiles derived from subjects’ Baseline BMI values. 
To allow for an analysis of PK trough levels for bimekizumab administration via self-injection or 
via study personnel administration, pre-dose PK samples will be taken throughout the DV0002 
substudy. For the Q4W dose regimen, PK trough levels will be determined based on pre-dose PK 
sampling at Baseline and Week 8 for the study personnel administration and at Week 4 and 
Week 12 for the self-administration trough levels, respectively. For the Q8W dose regimen, PK 
trough levels will be determined based on pre-dose PK sampling at Baseline for the study 
personnel administration and at Week 8 and Week 16 for the self-administration trough levels, 
respectively. For the analysis of PK trough levels by injection site (abdomen or thigh) and by

Section 14.10 Determination of sample size 
This study will not be powered with respect to any endpoint and sample size is based on practical 
considerations. In order to maintain blinding in the PS0014 feeder studies, DV0002 will recruit 
subjects who were administered bimekizumab 320mg (Q4W or Q8W) and subjects who were 
administered placebo or ustekinumab in the PS0014 feeder studies. A total of 100 subjects 
(50 subjects per device arm) are planned for PK trough level analyses, but these analyses can 
only be performed on subjects who do not change their bimekizumab dose or dosing regimen 
(ie, 320mg bimekizumab Q4W or Q8W) between the PS0014 feeder studies and in the DV0002 
substudy. The DV0002 substudy will therefore enroll approximately 200 subjects (to compensate 
for subjects with bimekizumab dose changes) to ensure that 100 subjects are available for PK 
trough analysis. 
Subjects who enroll in the DV0002 substudy will be randomly assigned to the 
bimekizumab-SS-1mL or the bimekizumab-AI-1mL device arms (each device arm will consist 
of approximately 100 subjects). Within each device arm, subjects will be divided into tertiles by 
BMI; there will be approximately 33 subjects per tertile, which is expected to yield 
approximately 16 to 17 subjects per tertile who are evaluable for steady state trough PK level 
analyses.

dose regimen for at least 16 weeks, and thus all will be evaluable for the PK trough level 
analyses.
