Amendment 1
13 March 2017
Amendment 2
05 July 2017
The purpose of this amendment is to implement the following changes:
●
Section 1.0, Title Page:  to change the Emergency Contact, Therapeutic Area 
Medical Director´s fax number.
Rationale:  New fax number.
●
Section 5.2.1, Inclusion Criteria:  removal of the following redundancy: 
"Females of non-childbearing potential (either postmenopausal or permanently 
surgically sterile as defined above) at Screening do not require pregnancy 
testing at Study Day 1."
Rationale:  Editorial change.
●
Section 5.2.3.3, Prohibited Therapy:  moving the time point from which 
phototherapy (e.g., UVA, UVB, any other UV-therapy or balneotherapy) not-
associated with systemic UV-sensitizing agents, topical treatment for psoriasis 
or any other skin condition (e.g., corticosteroids,c vitamin D analogues, 
vitamin A analogues, pimecrolimus, retinoids, salicylvaseline, salicylic acid, 
lactic acid, tacrolimus, tar, urea, andanthralin, α-hydroxy acid, fruit acids) are 
prohibited from 14 days prior to Screening  to 14 days prior to Baseline.
Rationale:  The half-life of those therapies is short and no interaction with 
study medication is to be expected if they are discontinued 14 weeks before 
1st dose of study medication, i.e., 14 days before Baseline (Day 1, Week 0).  
●
Section 5.3.1.1, Study Procedures, and Appendix C, Study Activities:  
FUMADERM® INITIAL and FUMADERM® Subject Diary:  Clarification 
that the subject diary will be dispensed to the subject at every visit, starting at 
the Week 0/Baseline Visit rather than at the Screening Visit, and that the 

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
3
subject will be trained on how to complete the diary at the Week 0/Baseline 
Visit.
Rationale:  Clarification.
●
Section 5.4.1.1, Discontinuation of Subjects on FUMADERM®:  Point 8:  
Restriction of the discontinuation of the subjects on FUMADERM® for 
rash/flush to those with severe rash/flush.
Rationale:  In clinical practice only severe persistent rash/flush leads to 
discontinuation of the patients from FUMADERM®.
The FUMADERM® label language does not request discontinuation of 
FUMADERM® treatment for all adverse events of rash/flush, but says: "… 
severe forms (of rash/flush) may lead to (FUMADERM®) treatment 
discontinuation." 
●
Section 5.5.1, Treatments Administered:  the sentence "Additional dosing 
instructions will be provided separately from this protocol" has been removed.
Rationale:  Risankizumab will be administered by site personnel only, 
therefore no additional instructions on how to administer an SC injection is 
required.
●
Appendix J, NAPPA-CLIN®:  Extension of the prohibition of artificial nail 
and/or nail polish to all subjects instead of subjects with nail psoriasis only.
Rationale:  Consistency within the protocol.  The analysis of the efficacy on 
nail psoriasis is planned on all subjects regardless of a concomitant nail 
psoriasis.
An itemized list of all changes made to this protocol under this amendment can be found 
in Appendix K.

Synopsis
AbbVie Inc.
Protocol Number:  M16-178
Name of Study Drug:  Risankizumab 
Phase of Development:  3
Name of Active Ingredient:  Risankizumab 
Date of Protocol Synopsis:  28 November 2017
Protocol Title:  A Randomized, Controlled, Multicenter, Open Label Study with Blinded Assessment of 
the Efficacy of the Humanized Anti-IL-23p19 Risankizumab Compared to FUMADERM® in Subjects 
with Moderate to Severe Plaque Psoriasis who are Naïve to and Candidates for Systemic Therapy
Objective:  
The objective of this study is to compare the efficacy and safety of subcutaneous (SC) risankizumab and 
oral FUMADERM® provided as study medication in subjects with moderate to severe plaque psoriasis 
who are naïve to and candidates for systemic therapy.
Investigator:  Investigator information on file at AbbVie.
Study Site:  Approximately 25 sites in Europe
Study Population:  
Adults with moderate to severe plaque psoriasis [Psoriasis Area and Severity Index (PASI > 10), 
affected body surface area (BSA) > 10% and Dermatology Life Quality Index (DLQI) > 10] who are 
naïve to and candidates for systemic therapy.
Number of Subjects to be Enrolled:  Approximately 110 [2 × 55]
Methodology:  
This study is a randomized, controlled, multicenter, open-label study with blinded assessment of efficacy 
to demonstrate the efficacy and safety of SC risankizumab in adult subjects with moderate to severe 
plaque psoriasis who are naïve to and candidates for systemic therapy compared with oral 
FUMADERM® provided as study medication.  This study will be conducted in approximately 
110 subjects.
Subjects will be randomized in a 1:1 ratio (stratified by prior phototherapy, with a maximum of 20% of 
subjects with prior phototherapy) to one of two arms of either risankizumab or oral FUMADERM®
provided as study medication.  The following are the dosing arms:
!
Risankizumab 150 mg SC at Week 0/Day 1, Week 4 and Week 16 or,
!
Oral FUMADERM® provided as study medication daily starting at Week 0/Day 1 and until 
Week 24 (last intake in the morning on the day of Week 24 visit):
FUMADERM® INITIAL provided as study medication starting at Week 0/Day 1 until Week 2 
and FUMADERM® provided as study medication starting at Week 3, both at starting dose of 
1 tablet per day, followed by an increase in the daily dose of 1 tablet per week, with the 
intention of achieving PASI 90.  The maximum daily dose of FUMADERM® provided as study 
medication may not exceed 6 tablets per day.  After the targeted efficacy on the psoriasis 
cutaneous lesions has been reached, an attempt should be made to reduce the dose of 
FUMADERM® provided as study medication to the individual maintenance dose.
Efficacy outcomes will be measured at each visit until Week 24 and safety data will be collected 
throughout the study.

Statistical Methods:
Efficacy:
The efficacy analysis will be performed in the Intent to Treat (ITT) set which includes all subjects who 
are randomized.
The primary efficacy endpoint (PASI90 at Week 24) will be analyzed using a two-sided Cochran-Mantel 
Haenszel test stratified by prior phototherapy at level of significance 5%.  Missing data will be imputed 
using non-responder imputation, i.e., a subject with missing PASI90 at Week 24 will be considered a 
non-responder in the primary analysis.
For categorical secondary endpoints, the same statistical test as for the primary endpoint will be used, 
missing data will be imputed using non-responder imputation.  For continuous secondary endpoints, 
two-sided two-way ANOVA will be used with treatment and prior phototherapy as factors and missing 
data will be imputed using last observation carried forward (LOCF). 
Secondary endpoints will not be used for confirmatory interpretation, thus no adjustment for multiplicity 
will be done.
Pharmacokinetics (PK) and Immunogenicity:
Risankizumab serum concentrations will be determined.  Descriptive statistics will be calculated for each 
sampling time (study visit).  The number and percentage of subjects with ADA will be calculated.
Additional analyses combining pharmacokinetic and ADA data from this study and other studies may be 
conducted if appropriate.  
Safety:
The safety analysis will be performed in the safety set which includes all subjects who received at least 
one dose of study drug.
Treatment-emergent adverse events will be tabulated by system organ class and preferred term, whereby 
the most current implemented MedDRA dictionary will be used.  Also, summaries by severity and 
relationship to study drug will be done.  Certain adverse events, like serious or severe, leading to 
discontinuation, will be listed and described in detail.  Adverse events of interest for treatment with 
biologics will be defined in the statistical analysis plan and analyzed separately.
Adverse events will be summarized by frequency and percentage and presented by treatment group, 
statistical comparisons will be performed using Fisher's exact test.
Other safety variables like laboratory data and vital signs will also be described by descriptive statistics 
for each treatment group.  Treatment comparisons will be performed by one way ANOVA.  In addition, 
shift tables and listings will be provided for abnormal values, whereby the normal range of the analyzing 
laboratory will be used.

Introduction
Psoriasis is a chronic inflammatory disease with raised, well-demarcated erythematous 
plaques with adherent silvery scales.2  It is the most prevalent immune mediated skin 
disease, affecting 2% of the world population.3  Twenty-five percent of patients have 
moderate to severe disease with considerable negative impact on psychosocial and 
economic status.4  It is increasingly recognized that psoriasis is more than a superficial 
disease, with 30% of patients having joint involvement and a high correlation between 
psoriasis and obesity, diabetes, depression, metabolic syndrome and cardiovascular risk.5
While the majority of psoriasis patients are managed initially with topical therapies, those 
with severe and/or refractory disease may require phototherapy and/or systemic therapy.  
Oral systemic agents provide modest efficacy, but increasingly patients are treated with 
biological agents such as tumor necrosis factor (TNF)-alpha inhibitors (etanercept, 
adalimumab) and the interleukin (IL)-12/23 inhibitor (ustekinumab).6  While the clinical 
efficacy of ustekinumab indicates a role for both IL-12 and IL-23 in the pathogenesis of 
psoriasis,7 more recent data suggest that IL-23 is disproportionately involved in the 
maintenance of chronic psoriasis.7  IL-23 is thought to be involved in the pathophysiology 
of psoriasis via induction and maintenance of Th17 type cells, and other IL-23 responsive 
cells.  This is supported by recent clinical data indicating that monoclonal antibodies 
(mAb) that block IL-17, the cytokine produced by Th17 cells, have high efficacy in 
psoriasis.8
There is still clinical need for increased efficacy as the most effective anti-TNF and 
IL12/23 agents provide approximately 75% improvement in psoriasis in about 60 – 70% 
of patients and these responses tend to be lost over time.  While the anti-IL-17 agents 
(i.e., secukinumab) may provide better efficacy, they require monthly injections, thus their 
long term utility is still undetermined.8
Risankizumab is a fully humanized mAb of the IgG1 subclass directed towards IL-23p19.  
The antibody has been engineered to reduce Fcγ receptor and complement binding and 
potential charge heterogeneity.  Risankizumab binds with high affinity to human IL-23 

Risankizumab

and inhibits IL-23 stimulated IL-17 production at inhibitory concentration (IC) 50 
concentrations below 10 pM, as compared with 167 nM for ustekinumab in the same 
system.  Risankizumab does not affect IL-12 at a maximum tested concentration (33 nM) 
and it does not inhibit IL-12 stimulated IFN-γ production.
The toxicology data suggest that risankizumab can be safely administered to humans, as 
supported by chronic administration to monkeys for up to 26 weeks.  The monkey was 
identified as the most relevant toxicology species with no observed adverse effect level 
(NOAEL) of 50 mg/kg/dose, corresponding to an exposure (combined sex) of 677 μg/mL 
for the maximal concentration (Cmax) and 86,250 μg•h/mL for area under the curve (AUC) 
0 – 168, respectively.
In Phase 1 and Phase 2 risankizumab has been studied in approximately 200 subjects with 
psoriasis without any unexpected adverse events (AEs) or safety signals.  Based on the 
efficacy and safety findings in the completed and ongoing studies, the risk benefit profile 
of risankizumab is appropriate for further conduct of Phase 3 studies.  In the Boehringer 
Ingelheim (BI) Study 1311.1,9 a Phase 1 single rising dose study in 39 subjects with 
chronic plaque psoriasis, both intravenous (i.v.) and subcutaneous (s.c.) administration of 
risankizumab was well tolerated.  Over the 24 weeks following a single i.v. or s.c. 
administration of risankizumab, 65% (20/31) of subjects experienced an adverse event 
(AE) compared with 88% (7/8) of subjects receiving placebo.  There was no relationship 
between the overall frequency of AEs and treatment groups, or between the occurrence of 
AEs in specific system organ classes, or individual AEs, and treatment groups.  
Four serious adverse events (SAE) were reported in subjects receiving risankizumab.  All 
resolved without sequelae and were considered unrelated to study treatment.
After a single i.v. administration, risankizumab geometric mean AUCAUC0-inf ranged 
from 2.93 – 1650 day•μg/mL and Cmax from 0.311 – 110 μg/mL, with exposure increasing 
in a dose-proportional manner.  Group mean clearance and terminal phase volume of 
distribution were 0.33 L/day and 10.8 L, respectively.  Based on all dose groups, the 
absolute bioavailability of risankizumab after SC administration was estimated to be 73%.

Risankizumab

In a 48 week Phase 2 dose ranging study of risankizumab vs. ustekinumab in 
166 subjects, approximately 73% of subjects reported an AE; the most common were 
nasopharyngitis (32% of 126 subjects in risankizumab arms), headache (9%), back pain 
(6%) and arthralgia (5%).  Overall, there was no difference in the AEs across treatment 
groups and no evidence of a dose effect for any AE.  During the 48-week study, 
11 subjects (8.7%) on risankizumab reported at least 1 serious adverse event. One subject 
administered risankizumab (90 mg) experienced an SAE that was considered related to 
study treatment (basal cell carcinoma).  All other SAEs were considered unrelated to 
study treatment.  
Treatment with 90 or 180 mg risankizumab resulted in a higher percentage of subjects 
satisfying and maintaining Psoriasis Area and Severity Index (PASI) 90 through Week 48 
as compared with ustekinumab and risankizumab 18 mg.10

The 12 week data indicate a 37% greater improvement for risankizumab (90 mg and 
180 mg, pooled data) compared to ustekinumab in the proportion of subjects achieving 
PASI 90.10
The current study compares the safety and efficacy of risankizumab versus Fumaderm®
provided as study medication in subjects with moderate to severe psoriasis.
For a more detailed description of the drug profile, refer to the latest version of the 
investigator's brochure (IB).9
Fumaric acid esters was approved in Germany as systemic therapy for the treatment of 
psoriasis in 1995.  The commercial product, Fumaderm® contains a mixture of dimethyl 
fumarate (DMF) and three salts of ethyl hydrogen fumarate.  DMF is considered to be the 
actual active ingredient.1
Most of the reports on the clinical effects of Fumaderm® on psoriasis are from open label 
studies that consistently showed that a significant improvement in the condition of the 
skin is reached over a period of about 3 months of treatment.1-16
Preliminary results of a recent adequate and well controlled clinical study including a 
Fumaderm® arm indicate that PASI 75 and PGA 0 or 1 responses were achieved at 
Week 16 in 40.3% and 37.4% of the subjects treated with Fumaderm®, whereas 22.3% of 
the subjects achieved PASI 90 at Week 16.17
Serious adverse events were reported in 2.8% of the subjects and discontinuation due to 
adverse events occurred in 24% of the subjects receiving FUMADERM®.  The most 
frequently reported treatment-emergent adverse events (TEAEs) were gastrointestinal 
disorders, including diarrhea (39.9%), upper abdominal pain (22.6%), abdominal pain 
(15.9%) and nausea (8.5%).  Flushing was also commonly reported (16.3%) as well as 
pruritus (9.9%).  Lymphopenia was observed in 10.6% of the subjects and was considered 
severe in two subjects (0.07%).  Erythema, headache and nasopharyngitis were also 
reported (8.1% each).  Proteinuria was reported in 2.1% of the subjects.

3.1
Differences Statement
The present study will only include subjects with moderate to severe plaque psoriasis who 
are naïve to systemic therapy, whereas the subjects included in the worldwide 
risankizumab psoriasis development program may have previously been exposed to 
biologic or non-biologic systemic treatment for psoriasis.
The comparator will be fumaric acid esters, commercialized as FUMADERM® in 
Germany whereas the ongoing studies of risankizumab use placebo, ustekinumab or 
adalimumab as comparators.
One further difference between other studies of risankizumab in psoriasis and this study 
relates to the definition of moderate to severe psoriasis, which, for this study, is defined as 
PASI > 10, body surface area (BSA) > 10% and dermatology life quality index (DLQI) 
> 10, this later definition being based on a European consensus decision.1,18  In other 
studies of risankizumab, moderate to severe psoriasis is defined as PASI ≥ 12, BSA 
≥10% and static physician global assessment (sPGA) ≥ 3.
3.2
Benefits and Risks
In Phase 1 and Phase 2 studies of risankizumab in patients with psoriasis, the majority of 
subjects receiving risankizumab achieved 90% improvement of their disease and 
risankizumab was well tolerated.  
As with many immune modulating agents, risankizumab may impair immune function 
resulting in a risk of infection.  This will be monitored by collection of all AEs during the 
treatment and observation periods.
Subjects with active infection will not be included in the study.
Subjects with a positive QuantiFERON®-test or a positive Purified Protein Derivative 
(PPD) skin test for tuberculosis (TB) must fulfill entry criteria as specified in 
Section 5.2.1 of this protocol.  Interleukin-23 inhibition is not known to increase the risk 
of TB infection or impair the response to TB infection in animal models.19,20  Thus, low 

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
21
risk subjects with positive Quantiferon testing do not need to be treated with anti-
tuberculosis therapy prior to receiving risankizumab, but should be carefully monitored 
for any sign of TB reactivation.  Absence of TB reactivation, despite not receiving 
anti-tuberculosis prophylaxis will provide important information in humans as to whether 
TB testing is required prior to treatment with risankizumab.21
There is not enough information at this time to rule out a risk of cancer with 
risankizumab, but this risk is considered small with this type of compound as experience 
with the anti-Il-12/23 mAb ustekinumab has not suggested significant risk for cancer or 
serious infection.
Increases in major adverse cardiovascular (MACE) events including myocardial 
infarction, cerebrovascular accident, and cardiovascular death, reported initially with 
anti-IL-12/23 agents, such as ustekinumab, have not been observed in longer term studies.  
Although rare, a potential for drug-induced liver injury (DILI) is under constant 
surveillance by sponsors and regulators.  Therefore, this study requires timely detection, 
evaluation, and follow-up of laboratory alterations in selected liver laboratory parameters 
to ensure subjects' safety.
In conclusion, the benefit-risk profile of risankizumab is considered appropriate for this 
stage of clinical development.
Fumaderm® is a widely prescribed systemic therapy for moderate to severe psoriasis, 
although registered for this indication in Germany only, a high proportion of patients 
treated with FUMADERM® experience a significant improvement in their psoriatic skin 
disease over a period of about 3 months of treatment.1
The safety profile of FUMADERM® is well characterized.  Gastrointestinal complaints 
(in up to 60% of subjects especially in the initial weeks of therapy) and flush are the most 
common side effects of fumaric acid esters.  Gastrointestinal tract symptoms include 
diarrhea, increased frequency of stools, nausea, and abdominal cramps.  The symptoms of 
flush are highly variable and range from a brief feeling of warmth to reddening of the face 

Risankizumab
M16-178 Protocol Amendment 3

22
lasting for several hours.  Leukocytopenia, lymphocytopenia, and eosinophilia are 
common side effects of fumaric acid esters.  The other adverse events reported in 
association with FUMADERM® remain uncommon to very rare:  acute lymphocytic 
leukemia, increase in liver function tests, Fanconi syndrome, opportunistic infection 
increases including isolated cases of progressive multifocal encephalopathy. 
There is no known association of FUMADERM® with malignancy.1,22
There are no studies on the use of fumaric acid esters during pregnancy or in nursing 
women.  Toxicology studies have shown that fumaric acid esters have neither teratogenic 
nor mutagenic potential.
The well codified dosing schedule for FUMADERM®, based on individual efficacy and 
safety response and the long experience in clinical practice since its commercialization 
guarantees an acceptable risk-benefit balance.  Pregnancy and breastfeeding as well as 
severe liver, kidney and gastrointestinal diseases are contraindication to Fumaderm®.

The study will include a 30-day screening period and a 24 week active-controlled 
treatment period followed by a follow-up phone call at Week 31 for subjects that do not 
elect to enroll into the extension study.  The maximum study duration is approximately 
35 weeks for subjects that do not elect to enroll into the extension study and 
approximately 28 weeks for subjects that do participate in the extension study.  This study 
was designed to enroll 110 subjects to meet scientific and regulatory objectives without 
enrolling an undue number of subjects in alignment with ethical considerations.  
Therefore, if the target number of subjects has been enrolled, there is a possibility that 
additional subjects in screening will not be enrolled.
After meeting the selection criteria, enrolled subjects will be randomly assigned in a 
1:1 ratio to one of two arms as shown below:
●
Risankizumab 150 mg SC at Week 0/Day 1, Week 4 and Week 16 or,
●
Oral FUMADERM® INITIAL provided as study medication starting at 
Week 0/Day 1 until Week 2 and FUMADERM® provided as study medication 
starting at Week 3 until Week 24 (last intake in the morning on the day of 
Week 24 visit):
Screening Period 
Within 30 days prior to the Week 0/Day 1 visit, subjects will receive a full explanation of 
the study design and study procedures, provide a written informed consent, and undergo 
the screening procedures outlined in Appendix C.
Paper diaries for FUMADERM® INITIAL and FUMADERM® (provided as study 
medication) dosing will be provided to the subjects at the visits outlined in Appendix C.
Subjects that initially screen-fail for the study may be permitted to re-screen one time 
following re-consent.
●
A repeat of all screening procedures is needed with the possible exceptions 
noted below.

○
If the subject had a complete initial screening evaluation including the 
assessment of an Interferon-Gamma Release Assay (IGRA; QuantiFERON 
Tuberculosis [TB] Gold In Tube test) or a purified protein derivative 
(PPD) test (or equivalent), and electrocardiogram (ECG), these tests will 
not be required to be repeated for re-screening provided the conditions 
noted in Section 5.3.1.1 are met.  
●
There is no minimum period of time a subject must wait to re-screen for the 
study.  If there is an exclusionary laboratory result during screening or 
re-screening within the 30 day screening window, one re-test of that particular 
value is allowed without repeating all other laboratory tests.  
●
The subject must meet all inclusion and none of the exclusion criteria at the 
time of re-screening in order to qualify for the study.  
Treatment Period
This period will begin at the Week 0/Day 1 (Baseline) Visit and will end at the 
Week 24/Early Termination (ET) Visit.  At the Baseline Visit, subjects who meet all the 
inclusion criteria and none of the exclusion criteria described in Section 5.2 will be 
enrolled into the study and randomized to open-label treatment.  During this period of the 
study, subjects will visit the site at Week 0 (Day 1/Baseline), Week 4, Week 8, Week 12, 
Week 16, Week 20 and Week 24/ET.  A ± 4 day window is permitted around scheduled 
study visits.  If any visit has to be rescheduled, subsequent visits should follow the 
original visit date schedule.  Visits should take place on the same day of the week as much 
as possible.  At the Week 24 visit, subjects who have completed the study will be offered 
the opportunity to participate in a separate extension study.  For subjects that do not elect 
to enroll into the extension study, a follow-up phone call will be performed at Week 31.
Safety data will be collected throughout the treatment period and up to 15 weeks after the 
last dose of risankizumab and/or 7 weeks after the last dose of FUMADERM® provided 
as study medication in this study.  Subjects may discontinue study drug treatment at any 
time during study participation.  Subjects that discontinue the study prior to Week 24 will 
have an ET visit and complete the procedures outlined in Appendix C within 2 weeks 

Risankizumab
M16-178 Protocol Amendment 3

25
after the decision to discontinue and preferably prior to the administration of any new 
therapies.
Follow-Up Period
Subjects will have a follow-up phone call at approximately Week 31 (approximately 
15 weeks after the last dose of risankizumab and 7 weeks after the last dose of 
FUMADERM® provided as study medication) with the exception of those subjects that 
elect to enroll into the extension study.  All follow-up phone call procedures are noted in 
Appendix C.

Efficacy and Safety Assessments/Variables
5.3.1
Efficacy and Safety Measurements Assessed 
Study procedures described are listed in the following section of this protocol and are 
summarized in tabular format in Appendix C.

5.3.1.1
Study Procedures
Study procedures will be performed at the study visits as specified in Appendix C.  Study 
visits are scheduled at Week 0/Day 1, Weeks 4, 8, 12, 16, 20 and 24/ET.  Study 
procedures are discussed in detail in this section, with the exception of drug concentration 
measurements and antibody measurements (discussed in Section 5.3.2), study drug 
administration (discussed in Section 5.5.1), and the collection of AE information 
(discussed in Section 6.1.1.1).  All study data will be recorded in source documents and 
on the appropriate eCRFs.
Informed Consent
The subject will sign and date a study specific, Independent Ethics Committee 
(IEC)/Institutional Review Board (IRB) approved, informed consent form before any 
study specific procedures are performed in order to participate in this study.  Details 
regarding how informed consent will be obtained and documented are provided in 
Section 9.3.
Inclusion/Exclusion Criteria
Subjects will be evaluated to ensure they meet all inclusion criteria and have none of the 
exclusion criteria at the Week 0/Day 1 visit.
Medical and Surgical History
A complete medical history, including history of tobacco, nicotine-containing products 
and alcohol use and ClASsification criteria for Psoriatic Arthritis (CASPAR)24
classification will be taken from each subject during the Screening Visit.  An updated 
medical history will be obtained prior to study drug administration and updated as 
necessary.  Phototherapy and topical psoriasis medication history prior to Baseline visit, 
other medication (prescription or over-the-counter, including vitamins and/or herbal 
supplements) use at the time of enrollment and through the end of the study will also be 
recorded.

EudraCT 2016-003718-28
35
Demographics
The subject's demographic data, including year of birth, gender, race, and ethnicity will be 
collected.
Physical Examination
A complete or targeted physical examination will be performed at the designated study 
visits as specified in Appendix C.  A complete physical examination will include vital 
sign assessment and general appearance as well as evaluation of all organ systems.  
Targeted physical examination will include vital sign assessment and evaluation of organ 
systems associated with AE(s) symptoms or laboratory abnormalities.  Clinically relevant 
abnormal findings will be reported as baseline conditions or AEs.
All physical examination findings whether related to an AE or part of a subject's medical 
history will be recorded on the appropriate eCRF page.
Vital Signs
Vital signs evaluations will be performed at visits as shown in Appendix C.
This includes temperature, pulse rate, systolic/diastolic blood pressure and respiratory 
rate.  Respiratory rate, pulse rate, and blood pressure will be measured after subjects have 
been sitting comfortably for at least 5 minutes.  In the case of an elevated blood pressure 
(systolic blood pressure > 140 mmHg or a diastolic blood pressure > 90 mmHg) at initial 
measurement, the recommendations in Appendix D40 should be followed in order to 
screen the subjects that will require further explorations.  Measurement of vital signs 
should precede blood sampling to avoid the impact of blood sampling on the vital 
measurements.
12-Lead Electrocardiogram (ECG)
The 12-lead ECGs will be performed as scheduled in Appendix C.

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
36
ECGs will be recorded after the subjects have rested for at least 5 minutes in a supine 
position and will always precede blood sampling.  Six limb leads, as specified by 
Einthoven (I, II and III) and Goldberger (aVR, aVL, aVF), and six pre-cordial leads (V1 –
V6), according to Wilson, will be used.
ECGs may be repeated for quality reasons and the repeat used for analysis.  Additional 
ECGs may be collected for safety reasons at the Investigator's discretion.  Clinically 
relevant, abnormal findings will be reported as AEs.
The electronic version of the ECG is regarded as source data.  Dated and signed printouts 
will be stored in the subject's medical file. 
Pregnancy Testing
A serum pregnancy test will be performed for all female subjects at the Screening Visit 
and at any other visit if the urine pregnancy test is positive.  The serum pregnancy test 
will be sent to and performed by the central laboratory.  If the serum pregnancy test at 
screening is positive in a female of child bearing potential, the subject is considered a 
screen failure.  If the serum pregnancy test at screening is borderline, it should be repeated 
to determine eligibility.  If the repeat test is not negative, the subject must be 
excluded/discontinued.
A urine pregnancy test will be performed for all female subjects of child-bearing 
potential, by the site at the Baseline Visit prior to the first dose of study drug and at all 
subsequent visits.  More frequent pregnancy tests will be performed throughout the study 
if required per local/country requirements.
●
If the urine pregnancy test performed at the site is negative, then dosing with 
study drug may begin/continue.  
●
If the urine pregnancy test performed at the site is positive, dosing must not be 
started/must be withheld and a serum pregnancy test is required.  For the 
serum pregnancy test, follow the steps above.

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
37
A pregnant or breastfeeding female will not be eligible for participation or continuation in 
this study.
HIV Testing
Subjects with a known history of HIV infection are excluded from study participation.  
HIV testing will be conducted as part of the infection screening at the screening visit.  A 
subject will not be eligible for study participation if test results indicate a positive HIV 
infection.  AbbVie will not receive results from the testing and will not be made aware of 
any positive result.
Tuberculosis Screening
All subjects will be tested for TB by either the QuantiFERON-TB Gold Test (or 
equivalent) or a TB Skin Test (Purified Protein Derivative, PPD) at Screening visit as 
specified in Appendix C.  If the TB screening test [either, PPD or, the 
QuantiFERON®-TB Gold test (or Interferon gamma release assay (IGRA) equivalent)] is 
positive, or if there is a repeat indeterminate QuantiFERON®-TB Gold test (or IGRA 
equivalent) upon retesting, subjects may participate in the study if further work up 
(according to local practice/guidelines) establishes conclusively that the patient has no 
evidence of active tuberculosis.  If presence of latent tuberculosis is established, then 
tuberculosis prophylaxis should be pursued according to clinical judgment of investigator 
and local country guidelines.
●
QuantiFERON®-TB Gold Test will be analyzed by the central laboratory 
(QuantiFERON test is preferred over TB Skin Test).
●
If the QuantiFERON®-TB Gold Test is NOT possible (or if both the 
QuantiFERON®-TB Gold Test and the PPD Skin Test are required per local 
guidelines) the PPD Skin Test will be performed according to standard clinical 
practice.
●
The PPD Skin Test should be read by a licensed healthcare professional 
between 48 and 72 hours after administration.  A subject who does not return 
within 72 hours will need to be rescheduled for another skin test.

Risankizumab
M16-178 Protocol Amendment 3

38
●
The reaction will be measured in millimeters (mm) of induration and 
induration ≥ 5 mm is considered a positive reaction.  The absence of induration 
will be recorded as "0 mm" not "negative."
●
If PPD and/or the QuantiFERON®-TB Gold test (or IGRA equivalent) is 
positive, or if there is a repeat indeterminate QuantiFERON®-TB Gold test (or 
IGRA equivalent) upon retesting, subjects may continue in the study if further 
work up (according to local practice/guidelines) establishes conclusively that 
the subject has no evidence of active tuberculosis.
●
If the subject is diagnosed with active tuberculosis, the subject should not 
receive any further study drug and follow the premature treatment 
discontinuation procedure (Early EOT visit) in Section 5.4.1.
●
If presence of latent tuberculosis is established treatment should be initiated 
and maintained according to local country guidelines.  If latent tuberculosis 
occurs during the study, it is also necessary to report it as an adverse event in 
the source documents and eCRFs.
●
If subject had a positive QuantiFERON®-TB Gold or PPD test at Screening, 
the test should not be repeated
●
Subjects who have had an ulcerating reaction to the TB Skin Test in the past 
should not be re-exposed and should not be tested by a PPD skin test.
●
In the case of a tuberculosis-related adverse event, a TB supplemental form 
that provides additional information will be completed by the investigator or 
designee.
Blinded Efficacy Assessor
At all treatment visits, the subjects will be assessed for efficacy by a blinded efficacy 
assessor.  
Prior to all examinations by the efficacy assessor, a bandage of the previous risankizumab 
injection site(s) in the subjects randomized to risankizumab will be applied.

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
39
To maintain the efficacy assessor's blind to treatment, site personnel (except the blinded 
efficacy assessor) will put a bandage over a viable injection site location in those subjects 
who are receiving FUMADERM®.
A qualified physician (may be a non-dermatologist) or designee (may be a non-physician) 
from the site will be responsible for performing the efficacy assessments, including PASI, 
BSA, static physician global assessment (sPGA), palmoplantar psoriasis severity index 
(PPASI), psoriasis scalp severity index (PSSI) and nail assessment in psoriasis and 
psoriatic arthritis (NAPPA-CLIN), at all appropriate study visits.  The site will make 
every attempt to have the same qualified physician or designee perform these assessments 
throughout the study for each subject.  The efficacy assessor must remain blinded to 
patient's treatment, clinical laboratory results and all subject safety data during the course 
of the study.  The efficacy assessor will not view or discuss any subject specific safety 
data with the investigators or any other site personnel, with the exception of the 
dermatologic safety findings requiring urgent medical attention.  The efficacy assessor 
therefore cannot be the Principal Investigator. 
The efficacy assessor will not access patient's eCRF and will document the dermatologic 
assessments and potential dermatologic safety findings on paper worksheets that will be 
filed as source in the patient's record.
It is recommended that each study site has a designated back-up for the efficacy assessor.
The tasks of the blinded efficacy assessor are described in Table 2.

Clinical Laboratory Tests
Blood samples will be obtained for the laboratory tests listed ("complete lab") in Table 3
at Screening, Week 0, 8, 16 and 24 visits.  At Week 4, 12, 20 visits only "targeted lab," 
i.e., CBC with differential count (hematology), ALT, AST, gamma-GT, alkaline 
phosphatase (AP) and serum creatinine, will be obtained.  Blood draws should be 
performed after all clinical assessments and patient reported outcomes, ECGs, and vital 
sign determinations are obtained before study drug administration during a visit.
Urine samples will be obtained for urinalysis testing at all visits as listed in Table 3.  The 
central laboratory will be responsible for performing a macroscopic urinalysis (urine 

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28

dipstick) on the collected urine specimens.  Specified abnormal macroscopic urinalyses 
will be followed up with a microscopic analysis at the central laboratory.
A certified central laboratory will be utilized to process and provide results for the clinical 
laboratory tests.  All abnormal laboratory tests that are considered clinically significant by 
the investigator will be followed to a satisfactory resolution.  Laboratory abnormalities are 
considered to be adverse events only if they result in discontinuation from the study, 
necessitate therapeutic medical intervention, and/or if the Investigator considers them to 
be an adverse event.
Instructions regarding the collection, processing and shipping of these samples will be 
provided by the central laboratory chosen for this study.

normalization or stabilization or until an alternative explanation has been found.  
Clinical Assessments and Patient Reported Outcomes
Clinical and patient reported efficacy endpoints will be assessed over the course of the 
study at the time points defined in Appendix C.  Patient reported outcomes (PROs) should 
be completed by the patient on his/her own in a pre-specified order in a quiet area/room 
before any other visit assessments or treatments, and, if possible, before any interaction 
with the investigator or other members of the study team.  Details of the following clinical 
and efficacy assessments are listed in the appendices.  Details of the patient reported

EQ-5D-5L
Psoriasis Symptom Scale (PSS)
The PSS is a four-item PRO instrument that assesses the severity of psoriasis symptoms in 
patients with moderate to severe psoriasis.  The symptoms included are:  pain, redness, 
itching and burning from psoriasis.  Current symptom severity is assessed as a daily diary, 
using a 5-point Likert-type scale ranging from 0 (none) to 4 (very severe).  
Dermatology Life Quality Index (DLQI)26,27
The DLQI has been extensively used in clinical studies and has a large evidence base 
supporting reliability and validity.  The DLQI is a self-administered, ten-question 
questionnaire used to assess the effect of different skin diseases on a subject's quality of 
life, overall health, and disability status.  The questionnaire covers six domains including 
symptoms and feelings, daily activities, leisure, work and school, personal relationships 
and treatment and has a one week recall period.26,27  Each item is scored on a 4 point scale 
where a 0 score indicates "not relevant/not at all," and scores from 1 to 3 range from "a 
little," to "very much."  Question 7 is a "yes"/"no" question where "yes" is scored as 3.  If 
Question 7 is answered "no," scores range from 0 ("not at all") to 2 ("a lot").  
Medical Outcome Short Form Health Survey (SF-36) Version 2 (Acute Form)28,29
The SF-36 is a widely used and extensively studied instrument to measure health-related 
quality of life among healthy subjects and patients with acute and chronic conditions.  It 
consists of eight subscales that can be scored individually:  Physical Functioning, Role-
Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role-Emotional, and 
Mental Health.  Two overall summary scores, the Physical Component Summary (PCS) 
and the Mental Component Summary (MCS) also can be computed.  The SF-36 has 
proven useful in monitoring general and specific populations, comparing the relative 
burden of different disease, differentiating the health benefits produced by different 

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
46
treatments, and in screening individual subjects.  The purpose of the SF-36 in this study is 
to assess the Health Related Quality of Life (HRQoL) of subjects.  Given the acute nature 
of this disease, version 2, with a 1-week recall period, will be used in this study.
Patient Benefit Index (PBI)30,31
The PBI is a 25 item PRO instrument that assesses the benefit of psoriasis treatment.  
Patient relevant treatment needs and benefits are assessed through these 5 subscales:  
Reducing social impairment, reducing psychosocial impairments, reducing impairments 
due to therapy, reducing physical impairments, having confidence in healing.  Treatment 
benefit is assessed using the PBI score ranging from 0 ("no benefit") to 4 ("maximal 
benefit").  
Hospital Anxiety & Depression Scale (HADS)32,33,34
The HADS is a self-assessment scale which detects the presence and severity of anxiety 
and depression in the general population.  It contains 14 items and is comprised of anxiety 
(7 items) and depression (7 items) subscales, which are scored separately and summed to 
give a total score.  Item scores range from 0 (best) to 3 (worst) and total scores are 
categorized as normal (0 – 7), borderline abnormal (8 – 10) and abnormal (11 – 21).  The 
HADS has been widely used in clinical trials in a variety of disease areas and has 
extensive evidence to support its acceptability, reliability and validity.
Patient's Global Assessment (PtGA)35,36
The PtGA is a PRO instrument to assess the patient's assessment of disease severity.  This 
self-reported measure is used to assess disease activity using a 4-point scale where a 
higher score indicates higher level of disease activity.  Disease activity is assessed from 0 
("complete disease control") to 3 ("uncontrolled disease").  
European Quality of Life 5 Dimensions (EQ-5D)37
The EQ-5D is a standardized non-disease specific instrument for describing and valuing 
health-related quality of life.1  The EQ-5D consists of 5 dimensions:  mobility, self-care, 

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
47
usual activity, pain/discomfort, and anxiety/depression.  Each dimension has 5 levels:  no 
problem, slight problem, moderate problem, severe problem or unable to perform 
activity/extreme problem.  It also contains a Visual Analogue Scale (VAS).  Subjects are 
asked to indicate the level that describes their current level of function or experience for 
each dimension.  As a measure of health status, it provides a descriptive profile and can be 
used to generate a single index value for health status, where full health is equal to 1 and 
death is equal to 0.  The VAS records the subject's assessment of his/her own health along 
a vertical 20 cm line, which has health state scores between 0 and 100.  
FUMADERM® INITIAL and FUMADERM® Subject Diary
Subjects will be dispensed a paper diary at every visit, starting at the Week 0/Baseline 
visit and will be trained on how to complete the diary for FUMADERM® INITIAL and 
FUMADERM® (provided as study medication) dosing by site staff during the 
Week 0/Baseline visit.  All subjects should complete their subject diary on a daily basis 
throughout the entire study.  The diary will be reviewed by site personnel with the subject 
at each visit and collected at the Week 24/ET Visit.
The dosing records will be reviewed and verified for compliance at each visit by the site 
personnel at the study center and reinforced if necessary.  All relevant dosing information 
will be captured into the eCRF by site personnel.
Study Drug Administration
Refer to Section 5.5.1.
Monitoring for Hypersensitivity Reactions
A hypersensitivity reaction is a clinical sign or symptom, or constellation of signs or 
symptoms, caused by an inappropriate and excessive immunologic reaction to study drug 
administration.  A systemic hypersensitivity reaction is a hypersensitivity reaction that 
does not occur at the local site of study drug administration (e.g., not an injection site 
reaction).  A serious systemic hypersensitivity reaction is a systemic hypersensitivity 
reaction that fulfills criteria for a serious adverse event.

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
48
Subjects should be closely monitored for signs and symptoms of hypersensitivity 
reactions for approximately 2 hours after the first dose administration (Week 0/Day 1) and 
1 hour after all other doses of study drug (visits after Week 0/Day 1) in the patients 
randomized to risankizumab.  Hypersensitivity reactions should be treated according to 
medical standards.
In the event of a suspected hypersensitivity reaction or other systemic post-dose reaction, 
a (PK/ADA) blood and urine sample will be collected once within 24 hours of the

Collection of Samples for Analysis
Blood Samples for Risankizumab Assay
Blood samples, approximately 3 mL, for risankizumab assay will be collected by 
venipuncture into appropriately labeled collection tubes at the time points specified in 
Appendix C.  The timing of blood collection will take priority over all other scheduled 
study activities except for PROs, ECG and vital signs.  Blood samples for the PK assay 
should be collected as closely as possible relative to the time of dosing and within 
30 minutes prior to dosing.  Date and exact time (to the nearest minute) of drug 
administration will be recorded on eCRFs.  The time that each blood sample is collected 
will be recorded to the nearest minute in the source document.
A total of three samples will be collected per subject for pharmacokinetic analysis during 
the treatment and follow-up periods.

53
If, during the course of study drug administration, the subject prematurely discontinues 
study drug use, the procedures outlined for the Early Termination Visit must be completed 
within 2 weeks after the decision to discontinue, and preferably prior to the initiation of 
another therapy.  However, these procedures should not interfere with the initiation of any 
new treatments or therapeutic modalities that the Investigator feels are necessary to treat 
the subject's condition.  Following discontinuation of the study drug, the subject will be 
treated in accordance with the Investigator's best clinical judgment.
A final telephone call will occur for all subjects who do not roll over into the extension 
study, approximately 15 weeks after the last dose of risankizumab and 7 weeks after the 
last dose of FUMADERM®, provided as study medication, to determine the status of any 
ongoing AEs/SAEs or the occurrence of any new AEs/SAEs.
All attempts must be made to determine the date of the last study drug dose and the 
primary reason for early termination.  The information will be recorded on the appropriate 
eCRF page.
For subjects that are considered lost to follow-up, reasonable attempts must be made to 
obtain information on the final status of the subject.  At a minimum, two phone calls must 
be made and one certified letter must be sent and documented in the subject's source 
documentation.
Subjects who discontinue the study prematurely will not be replaced.
Subjects are considered study completers if they have completed the Week 24 visit.
5.4.1.1
Discontinuation of Subjects on FUMADERM®
Subjects that are randomized to FUMADERM® INITIAL or FUMADERM® should be 
discontinued if any of the following occur:
1.
A pronounced decrease in WBC count of > 50% between 2 visits or an absolute 
WBC count below 3,000/μl.

Treatments
5.5.1
Treatments Administered
Subjects randomized to risankizumab will receive SC injections of risankizumab in the 
form of 
 mg (150 mg total) pre-filled syringes at Weeks 0, 4 and 16.
Risankizumab will be administered as a SC injection in the abdomen, thighs, gluteal 
regions, or upper arms (contra-lateral to that used for pharmacokinetic 
(PK)/pharmacodynamics (PD) samples).  The two injections done subsequently should be 
at least 2 cm apart and should not be close to a vein.  The injection sites should avoid sites 
of psoriasis involvement as well as sites where the skin is tender, bruised, erythematous, 
or indurated and should be alternated to other areas for subsequent doses.  
Subjects randomized to FUMADERM® will receive doses as noted in Table 5.
FUMADERM® dose is increased with the intention of achieving PASI 90, if tolerability 
allows.  The decision of a slow increase in FUMADERM® INITIAL or FUMADERM®
dose or of a return to FUMADERM® INITIAL after initiation of FUMADERM® will be 
made by the investigator and the justifications for all deviations from the pre-specified 
dosing schedule of FUMADERM® will be documented in the eCRF.  The maximum daily 
dose of FUMADERM® may not exceed 6 tablets per day.  After the targeted efficacy on 
the psoriasis cutaneous lesions has been reached, an attempt should be made to reduce the 
dose of FUMADERM® to the individual maintenance dose.  FUMADERM® INITIAL 
and FUMADERM® tablets must be swallowed without chewing with plenty of liquid 
during and immediately after meals.  In general, care must be taken to ensure subjects 
drink sufficient liquids (i.e., 1½ to 2 liters) daily.
The dose of FUMADERM® INITIAL or FUMADERM® should be reduced if any of the 
following occur:
1.
A drop in lymphocyte count below 700/μl.
2.
A platelet count < 150 000/μl and ≥ 100 000/μl.

4.
Gastrointestinal disorders, nausea, abdominal cramps, diarrhea.
5.
Nervous system disorders (i.e., tiredness, dizziness or headache).
After dose reduction of FUMADERM®, the blood count should be monitored until it 
returns to normal.

Method of Assigning Subjects to Treatment Groups
All subjects will be centrally randomized using an Interactive Voice Response 
System/Interactive Web Response System (IVRS/IWRS).  Before the study is initiated, 
the telephone number/call-in directions and web based information for the IVRS/IWRS 
will be provided to each site.
All subjects will be assigned a unique identification number by the IVRS/IWRS at the 
Screening Visit.  Subjects who meet the inclusion and exclusion criteria defined in 
Section 5.2.1 and Section 5.2.2 respectively will be centrally randomized in a 1:1 ratio to 
one of two dosing arms at Week 0/Day 1 (Baseline).  The IVRS/IWRS will assign a 
randomization number according to the randomization schedule generated by the 
Statistics Department at AbbVie.
5.5.4
Selection and Timing of Dose for Each Subject
An IRT will be used to allocate study drug to subjects.  At visits where study drug is to be 
administered/dispensed, study sites will be required to complete the study drug resupply 
module in the IRT to receive assigned study drug/kit numbers.
Risankizumab will be administered at the study site by authorized site personnel 
(e.g., study nurse) after all study procedures have been completed. 
For subjects randomized to risankizumab, injections will be given in an open label fashion 
with each subject receiving  injections of risankizumab (
 mg) at each dosing visit.

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
60
In exceptional cases of missed or delayed visits, risankizumab should not be administered 
within 14 days of the prior dose.  There should be at least 14 days between 
two consecutive risankizumab administrations.
For subjects randomized to FUMADERM® INITIAL and FUMADERM®, drug will be 
provided to subjects for dosing at home as specified in Section 5.5.1.
Dose modifications or adjustments are not permitted for risankizumab.  The dose 
modifications or adjustments for FUMADERM® INITIAL and FUMADERM® will be 
according to the investigator's instructions.
If one or several doses of FUMADERM® are missed, the patient should re-initiate the 
treatment with FUMADERM® according to the individualized dosing schedule.  The 
subject should contact the site personnel or the investigator to confirm their dosing 
schedule.  Any further adjustment of FUMADERM® dosing based on patient's individual 
efficacy and safety response is at the discretion of the investigator.
5.5.5
Blinding
This is an open-label study; however, the efficacy assessor will be blinded to the patient's 
study treatment as noted in Section 5.3.1.1.
5.5.6
Treatment Compliance
The investigator or his/her designated and qualified representatives will
administer/dispense study drug only to subjects enrolled in the study in accordance with 
the protocol.  The study drug must not be used for reasons other than that described in the 
protocol.
Subjects randomized to the FUMADERM® INITIAL and FUMADERM® arm will record 
all subject dosing information on a subject dosing diary and will return the dosing diary at 
each visit.  Subjects will be instructed to return all drug cartons (even if empty) to the 
study site personnel at each Study Visit.  The study site personnel will document 
compliance for risankizumab and FUMADERM® INITIAL and FUMADERM®.

5.5.7
Drug Accountability
The investigator and/or named sub-investigators must agree not to supply study drug to 
any persons not enrolled in the study.
The Investigator or designee will verify that study drug supplies are received intact, at the 
appropriate temperature, (temperature recording devices [e.g., TempTales] are provided in 
the shipments), and in the correct amounts from the drug depot. 
This will be documented by signing and dating the proof of receipt (POR) or similar 
document included with each drug shipment and by registering the arrival of drug through 
the IRT.  The original POR note or similar document and the IRT confirmation sheet will 
be kept in the site files as a record of what was received.
An accurate (running) inventory of study drug will be kept by the site, and will include the 
kit number, lot number, subject number, Proof of Receipt number(s), the number of 
pre-filled syringes or FUMADERM® blisters dispensed, initials of person who 
dispensed/administered the drug, and the date study drug was administered for each 
subject.
All empty/used study drug packaging and used pre-filled syringes will be inventoried by 
the site and verified by the site monitor.  Each site will use their own sharps disposal 
container designated to store used pre-filled syringes for this study.  Empty/used study 
drug packaging and sharps containers will be retained (unless prohibited by local law or 
site policy/procedure) by the site for accountability and compliance purposes.  Study drug 
accountability will be completed via IRT, source documents, subject dosing diaries, and 
by visually inspecting the packaging and syringes in the sharps container whenever 
possible.  Used sharps containers should never be opened.  
An overall accountability of the study drug will be performed by the site and verified by 
an AbbVie monitor throughout the study and at the site close-out visit.  After verification 
of drug accountability, used syringes must be destroyed at the site according to local 
regulations governing biohazardous waste.  Destruction of used study supplies must be 

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
62
documented.  All unused supplies must be inventoried, accounted for and destroyed on 
site according to local procedures or regulation or returned to a destruction facility by the 
CRA.  A copy of the Drug Accountability Form, in accordance with instructions provided 
by the AbbVie monitor, will be included in the return shipments.
5.6
Discussion and Justification of Study Design
This is a parallel group, two arm, open-label study comparing risankizumab with 
Fumaderm® with a blinded assessment of efficacy. 
Although a double-blind study would have been preferable to potentially reduce bias, the 
logistical difficulties associated with blinding Fumaderm® led to a compromise on an 
open label-study with a blinded assessment of efficacy.
5.6.1
Discussion of Study Design and Choice of Control Groups
Fumaderm® is widely used for the treatment of psoriasis and is registered as 1st line 
treatment for moderate to severe psoriasis in Germany where it has a market share > 50%.  
Fumaderm® will be familiar to the participating investigators, particularly in Germany 
where the study will be initiated.  Alignment on the protocol Fumaderm® dosing 
adjustment, which are based on the labelled dosing instructions, is expected to be easy to 
achieve.
In spite of requesting dosing adjustment, Fumaderm® is suitable for a clinical study, since 
the labelled dosing recommendations are straightforward based on the routine assessment 
of efficacy and safety.
5.6.2
Appropriateness of Measurements
The primary efficacy endpoint will be PASI 90 at Week 24, which is in line with the 
Gemeinsamen Bundesausschusses (G-BA) strong requirement for "long-term" data and 
for a stringent endpoint reflecting a PASI response of at least 75% compared to Baseline.  
Although PASI 75 has been the primary efficacy variable recommended by the EMA for 

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
63
clinical trials in psoriasis subjects, the recent breakthroughs in this therapeutic field have 
led to using a more stringent criterion.
The secondary efficacy endpoints will evaluate the impact of study treatment on the 
different facets of the cutaneous disease as well as on multiple aspects of quality of life, 
which will also address a request from the G-BA.
5.6.3
Suitability of Subject Population
The subject enrolled are adults with moderate to severe plaque psoriasis PASI score of 
> 10, affected BSA > 10% and DLQI > 10 who are naïve to and candidates for systemic 
therapy.
Risankizumab will be positioned as first line systemic therapy for moderate to severe 
psoriasis and the study population corresponds to this target population.  The definition of 
moderate to severe psoriasis is derived from the European guideline1 and differs from that 
used in risankizumab pivotal studies [PASI ≥ 12, BSA ≥ 10% and sPGA ≥ 3].
The selection criteria relating to safety guarantee that the subjects enrolled can safely be 
treated with both study drugs, risankizumab and Fumaderm®, based on the current 
knowledge on those drugs.
5.6.4
Selection of Doses in the Study
Risankizumab is currently in Phase 3 development for treatment of subjects with 
moderate to severe chronic plaque psoriasis.  Four Phase 3 studies are currently ongoing, 
which have enrolled approximately 2100 subjects, and evaluating risankizumab dose of 
150 mg administered at Week 0, 4 and thereafter every 12 weeks.  The risankizumab 
dosing regimen selected for the current study is the same as used in the ongoing 
risankizumab Phase 3 studies.
The Fumaderm® dosing recommendations are taken from the Fumaderm® label, with the 
caveat that the dose will be increased until PASI 90 is achieved, if tolerance allows.

intermittent, the events must be of similar nature and severity.  Adverse events, whether in 
response to a query, observed by site personnel, or reported spontaneously by the subject 
will be recorded.
All adverse events will be followed to a satisfactory conclusion.

6.1.1
Definitions
6.1.1.1
Adverse Event
An adverse event (AE) is defined as any untoward medical occurrence in a patient or 
clinical investigation subject administered a pharmaceutical product and which does not 
necessarily have a causal relationship with this treatment.  An adverse event can therefore 
be any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of a medicinal (investigational) 
product, whether or not the event is considered causally related to the use of the product.
Such an event can result from use of the drug as stipulated in the protocol or labeling, as 
well as from accidental or intentional overdose, drug abuse, or drug withdrawal.  Any 
worsening of a pre-existing condition or illness is considered an adverse event.  
Worsening in severity of a reported adverse event should be reported as a new adverse 
event.  Laboratory abnormalities and changes in vital signs are considered to be adverse 
events only if they result in discontinuation from the study, necessitate therapeutic 
medical intervention, and/or if the investigator considers them to be adverse events.
An elective surgery/procedure scheduled to occur during a study will not be considered an 
adverse event if the surgery/procedure is being performed for a pre-existing condition and 
the surgery/procedure has been pre-planned prior to study entry.  However, if the 
pre-existing condition deteriorates unexpectedly during the study (e.g., surgery performed 
earlier than planned), then the deterioration of the condition for which the elective 
surgery/procedure is being done will be considered an adverse event.
6.1.1.2
Serious Adverse Events
If an adverse event meets any of the following criteria, it is to be reported to AbbVie a 
serious adverse event (SAE) within 24 hours of the site being made aware of the serious 
adverse event.
Death of Subject
An event that results in the death of a subject.

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
66
Life-Threatening
An event that, in the opinion of the investigator, would have 
resulted in immediate fatality if medical intervention had not 
been taken.  This does not include an event that would have 
been fatal if it had occurred in a more severe form.
Hospitalization or 
Prolongation of 
Hospitalization
An event that results in an admission to the hospital for any 
length of time or prolongs the subject's hospital stay.  This 
does not include an emergency room visit or admission to an 
outpatient facility.
Congenital Anomaly
An anomaly detected at or after birth, or any anomaly that 
results in fetal loss.
Persistent or 
Significant 
Disability/Incapacity
An event that results in a condition that substantially 
interferes with the activities of daily living of a study subject.  
Disability is not intended to include experiences of relatively 
minor medical significance such as headache, nausea, 
vomiting, diarrhea, influenza, and accidental trauma 
(e.g., sprained ankle).
Important Medical 
Event Requiring 
Medical or Surgical 
Intervention to 
Prevent Serious 
Outcome
An important medical event that may not be immediately 
life-threatening or result in death or hospitalization, but 
based on medical judgment may jeopardize the subject and 
may require medical or surgical intervention to prevent any 
of the outcomes listed above (i.e., death of subject, 
life-threatening, hospitalization, prolongation of 
hospitalization, congenital anomaly, or persistent or 
significant disability/incapacity).  Additionally, any elective 
or spontaneous abortion or stillbirth is considered an 
important medical event.  Examples of such events include 
allergic bronchospasm requiring intensive treatment in an 
emergency room or at home, blood dyscrasias or convulsions 
that do not result in inpatient hospitalization, or the 
development of drug dependency or drug abuse.
For serious adverse events with the outcome of death, the date and cause of death will be 
recorded on the appropriate case report form.
6.1.1.3
Area of Safety Interest
Additional information may be collected for the following events:

6.1.2
Adverse Event Severity
Intensity of AEs
The investigator will use the following definitions to rate the severity of each adverse 
event:
Mild
The adverse event is transient and easily tolerated by the subject.

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
69
Moderate
The adverse event causes the subject discomfort and interrupts the 
subject's usual activities.
Severe
The adverse event causes considerable interference with the subject's 
usual activities and may be incapacitating or life-threatening.
6.1.3
Relationship to Study Drug
The investigator will use the following definitions to assess the relationship of the adverse 
event to the use of study drug:
Reasonable 
Possibility
After consideration of factors including timing of the event, 
biologic plausibility, clinical judgment, and potential alternative 
causes, there is sufficient evidence (information) to suggest a 
causal relationship.
No Reasonable 
Possibility
After consideration of factors including timing of the event, 
biologic plausibility, clinical judgment, and potential alternative 
causes, there is insufficient evidence (information) to suggest a 
causal relationship.
For causality assessments, events assessed as having a reasonable possibility of being 
related to the study drug will be considered "associated."  Events assessed as having no 
reasonable possibility of being related to study drug will be considered "not associated."  
In addition, when the investigator has not reported a causality or deemed it not assessable, 
AbbVie will consider the event associated.
If an investigator's opinion of no reasonable possibility of being related to study drug is 
given, an Other cause of event must be provided by the investigator for the serious 
adverse event.
6.1.4
Adverse Event Collection Period
All adverse events reported from the time of study drug administration until 15 weeks 
following discontinuation of risankizumab and 7 weeks following discontinuation of 
FUMADERM® (provided as study medication) administration have elapsed will be

73
For medical devices, a product complaint also includes all deaths of a patient using the 
device, any illness, injury, or adverse event in the proximity of the device, an adverse 
event that could be a result of using the device, any event needing medical or surgical 
intervention including hospitalization while using the device and use errors.
Any information available to help in the determination of causality by the device to the 
events outlined directly above should be captured.
6.2.2
Reporting
Product Complaints concerning the investigational product and/or device must be reported 
to the Sponsor within 24 hours of the study site's knowledge of the event via the Product 
Complaint form.  Product Complaints occurring during the study will be followed-up to a 
satisfactory conclusion.  All follow-up information is to be reported to the Sponsor (or an 
authorized representative) and documented in source as required by the Sponsor.  Product 
Complaints associated with adverse events will be reported in the study summary.  All 
other complaints will be monitored on an ongoing basis.
Product Complaints may require return of the product with the alleged complaint 
condition (syringe).  In instances where a return is requested, every effort should be made 
by the investigator to return the product within 30 days.  If returns cannot be 
accommodated within 30 days, the site will need to provide justification and an estimated 
date of return.
The description of the complaint is important for AbbVie in order to enable AbbVie to 
investigate and determine if any corrective actions are required.

Statistical Methods and Determination of Sample 
Size
The specification described here is that envisaged at the time of planning the trial.  Should 
new evidence come to light as a result of running other trials before this trial is analyzed, 
or should new methods of analysis become available in the statistical literature, or should 
the trial be affected by unforeseen circumstances, it may be necessary to modify the 
analysis strategy.
The analysis strategy described below will be supplemented by a detailed statistical 
analysis plan (SAP), which will be completed prior to database lock.

8.1
Statistical and Analytical Plans
8.1.1
Analysis Populations
The intent-to-treat (ITT) population consists of all subjects who were randomized.  The 
safety population consists of all subjects who were randomized and received at least 
one dose of study drug.
In order to evaluate the impact of major protocol deviations on the results of the trial, 
additional sensitivity analyses may be performed on the per-protocol population, which 
excludes subjects with major protocol deviations from the ITT population.  If it is decided 
that this analysis should be performed, the criteria for exclusion of subjects from the 
protocol analysis will be fully defined and documented in the final SAP and before the 
database lock.
8.1.2
Planned Methods of Statistical Analysis
All statistical tests will be two-tailed.  The statistical tests for the primary endpoint will be 
performed at the significance level 0.05.  All P values will be rounded to 3 decimal 
places.  Descriptive statistics will be provided.  These include the number of observations, 
mean, standard deviation, minimum, median, quartiles and maximum for continuous 
variables, and counts and percentages for discrete variables.  The analyses will be 
performed using SAS® (SAS Institute Inc., Cary, NC, USA).
8.1.3
Demographic and Baseline Characteristics
Demographics and Baseline characteristics of the study subjects will be summarized for 
each treatment arm using descriptive statistics.  Statistical tests will be performed to 
assess the comparability of the treatment arms.  Continuous variables will be analyzed 
using one-way analysis of variance (ANOVA), and discrete variables will be analyzed 
using Chi squared test or Fisher's exact test as appropriate.
8.1.4
Analysis of Efficacy
All efficacy analyses will be performed in the ITT population.

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
76
The primary efficacy endpoint (PASI90 at Week 24) will be analyzed using a two-sided 
Cochran-Mantel Haenszel test stratified by prior phototherapy at level of significance 5%.  
Missing data will be imputed using non-responder imputation, i.e., a subject with missing 
PASI90 at Week 24 will be considered a non-responder in the primary analysis.  Further 
sensitivity analyses for the primary endpoint may be specified in the SAP prior to 
database lock.
For the analysis of categorical secondary endpoints, the same statistical test as for the 
primary endpoint will be performed, missing data will be imputed using non-responder 
imputation.  For the analysis of continuous secondary endpoints, two-sided two-way 
ANOVA with treatment and prior phototherapy as factors will be imputed using last 
observation carried forward (LOCF).
The order of the secondary endpoints does not reflect a ranking and secondary endpoints 
will not be used for confirmatory interpretation, thus no adjustment for multiplicity will 
be done.
Further details regarding the statistical analysis will be specified in the SAP.
8.1.5
Analysis of Safety
All safety analyses will be performed in the safety population.
Treatment-emergent adverse events are defined as events with an onset date on or after 
the first dose of study drug until 15 weeks (105 days) following the last dose of 
risankizumab or 1 week (7 days) after the last dose of FUMADERM® provided as study 
medication or until rollover into the extension study.  In a sensitivity analysis, adverse 
events with an onset date until 7 weeks (49 days) after the last dose of FUMADERM®
provided as study medication or until rollover into the extension study will be included.
SAEs and protocol-related non-serious AEs with onset after informed consent but before
the first study drug administration will be considered as pretreatment events and reported 
separately.

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
77
Adverse events will be tabulated by system organ class and preferred term, whereby the 
most current implemented MedDRA dictionary will be used.  Also, summaries by severity 
and relationship to study drug will be done.  Certain adverse events, like serious or severe, 
leading to discontinuation, will be listed and described in detail.  Adverse events of 
interest for treatment with biologics will be defined in the statistical analysis plan and 
analyzed separately.
Adverse events will be summarized by frequency and percentage and presented by 
treatment group, statistical comparisons will be performed using Fisher's exact test.
Other safety variables like laboratory data and vital signs will also be described by 
descriptive statistics for each treatment group.  Treatment comparisons will be performed 
by one way ANOVA.  In addition, shift tables and listings will be provided for abnormal 
values, whereby the normal range of the analyzing laboratory will be used.
8.1.6
Interim Analysis
No interim analysis will be done for this study.
8.1.7
Pharmacokinetic and Exposure-Response Analysis
Individual risankizumab serum concentrations will be tabulated and summarized with 
appropriate statistical methods.  In addition, ADA titers will be tabulated for each subject 
at the respective study visits.  The number and percentage of subjects with ADA will be 
calculated.
Additional analyses with combining pharmacokinetic and ADA data from this study and 
other studies may be conducted if appropriate; this may include exploratory analyses of 
the effect of ADA on risankizumab pharmacokinetics and efficacy as well as the 
relationships between exposure and clinical observations (efficacy or safety variables of 
interest).  Such analyses, if conducted, may be summarized in a separate report rather than 
in the clinical study report for this study.

8.2
Determination of Sample Size
Using a two-sided Chi squared test at level of significance 5%, the sample size of 
110 (2 × 55) subjects will provide 94% power assuming response rates of the primary 
endpoint (PASI90 at Week 24) of 70% for risankizumab and 35% for FUMADERM®.
These assumptions are in line with what has been observed in recent studies for 
Risankizumab (63/83 (75.9%) at Week 24)9 and FUMADERM® 61/273 (22.3%) of the 
subjects achieved PASI 90 at Week 16 in the FUMADERM® arm in the BRIDGE trial.15
8.3
Randomization Methods
An IVR/IWR system will be used to determine the randomization of subjects.  Detailed 
instructions for using the IVR/IWR system will be provided to the site personnel.
The randomization schedule will be prepared by the statistics department of AbbVie.  
Subjects who are eligible based on inclusion and exclusion criteria and have had all 
pre-randomization procedures performed will be randomized in a 1:1 ratio to receive 
risankizumab or FUMADERM® stratified by prior phototherapy, with a maximum of 20% 
of subjects with prior phototherapy.  Randomization will not be stratified by center due to 
the limited number of subjects per center.  Randomization will be done using an adequate 
block size.

hospital records, clinical and office charts, laboratory data/information, subjects' diaries or 
evaluation checklists, pharmacy dispensing and other records, recorded data from 
automated instruments, microfiches, photographic negatives, microfilm or magnetic 
media, and/or x-rays.  Data collected during this study must be recorded on the 
appropriate source documents.  The Investigator Awareness Date (SAE CRF) may serve 
as the source for this data point.  This adverse event data point required for eCRF 
completion can be entered directly in the eCRF.
The investigator(s)/institution(s) will permit study-related monitoring, audits, IEC/IRB 
review, and regulatory inspection(s), providing direct access to source data documents.
10.2
Case Report Forms
Case report forms (CRF) must be completed for each subject screened/enrolled in this 
study.  These forms will be used to transmit information collected during the study to 
AbbVie and regulatory authorities, as applicable.  The CRF data for this study are being 
collected with an electronic data capture (EDC) system called Rave® provided by the 
technology vendor Medidata Solutions Incorporated, NY, USA.  The EDC system and the
study-specific electronic case report forms (eCRFs) will comply with Title 21 CFR 
Part 11.  The documentation related to the validation of the EDC system is available 

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
81
through the vendor, Medidata, while the validation of the study-specific eCRFs will be 
conducted by AbbVie and will be maintained in the Trial Master File at AbbVie.
The investigator will document subject data in his/her own subject files.  These subject 
files will serve as source data for the study.  All eCRF data required by this protocol will 
be recorded by investigative site personnel in the EDC system.  All data entered into the 
eCRF will be supported by source documentation.
The investigator or an authorized member of the investigator's staff will make any 
necessary corrections to the eCRF.  All change information, including the date and person 
performing the corrections, will be available via the audit trail, which is part of the EDC 
system.  For any correction, a reason for the alteration will be provided.  The eCRFs will 
be reviewed periodically for completeness, legibility, and acceptability by AbbVie 
personnel (or their representatives).  AbbVie (or their representatives) will also be allowed 
access to all source documents pertinent to the study in order to verify eCRF entries.  The 
principal investigator will review the eCRFs for completeness and accuracy and provide 
his or her electronic signature and date to eCRFs as evidence thereof.
Medidata will provide access to the EDC system for the duration of the trial through a 
password-protected method of internet access.  Such access will be removed from 
investigator sites at the end of the site's participation in the study.  Data from the EDC 
system will be archived on appropriate data media (CD-ROM, etc.) and provided to the 
investigator at that time as a durable record of the site's eCRF data.  It will be possible for 
the investigator to make paper printouts from that media.
Patient Reported Outcome (PRO) data must be completed for each subject 
screened/enrolled in this study.  These data are being collected with an Electronic Patient 
Reported Outcome (ePRO) system called Trialmax, provided by the technology vendor 
CRF Health of Plymouth Meeting, PA, USA.  The ePRO system is in compliance with 
Title 21 CFR Part 11.  The documentation related to the system validation of the ePRO 
system is available through the vendor, CRF Health, while the user acceptance testing of 
the study-specific PRO design will be conducted and maintained at AbbVie.

Recommendations on the Technique of Blood Pressure 
Measurement
Proper techniques to measure blood pressure are important to ensure consistent and 
reliable measurements.  The purpose of the recommendations below is to screen in routine 
practice the patients that will require explorations in a specialized department.40
1.
If anatomical conditions, deformity or surgical history interfering with proper 
access or blood flow to the upper arm, use the opposite arm for the blood pressure 
measurement
2.
Use a high quality and well calibrated equipment
3.
Prepare the patient
●
The examination room should be quiet, with a comfortable ambient 
temperature.
●
Ideally, blood pressure should not be measured if the patient has engaged in 
recent physical activity, used tobacco, ingested caffeine, or eaten within the 
past 30 minutes
●
Correct positioning of the patient is essential. 
○
The patient's back and legs should be supported, with the legs uncrossed 
and the feet resting on a firm surface.
○
The arm in which blood pressure will be measured should be bare to the 
shoulder, and the garment sleeve, if raised, should be loose, so that it does 
not interfere with blood flow or with proper positioning of the blood-
pressure cuff.
○
The arm should be supported and level with the heart.  The manometer 
should be positioned at the health care practitioner's eye level.
4.
Make sure that you are using the properly fitted cuff (undersized cuffs will result in 
overestimation of blood pressure)
●
Selection of an appropriately sized cuff requires assessment of the patient's 
arm circumference at the midpoint of the upper arm. 

Risankizumab
M16-178 Protocol Amendment 3
EudraCT 2016-003718-28
98
5.
Place the cuff on a bare arm, approximately 2 cm above the elbow crease, with the 
midline of the bladder (usually indicated by the manufacturer) directly over the 
brachial artery.  It should fit snugly but should still allow for two fingers to slide 
under the cuff.
6.
Estimate the systolic blood pressure by first measuring pulse-obliteration pressure
7.
For blood pressure measurement, proceed as follows:
●
Place the bell of the stethoscope over the brachial artery, using sufficient 
pressure to provide good sound transmission without over-compressing the 
artery.  To avoid extraneous noise during cuff deflation, ensure that the 
stethoscope is not in contact with the patient's clothing or with the blood-
pressure cuff.
●
Initiate the auscultatory blood pressure measurement by rapidly inflating the 
cuff to a level 20 to 30 mmHg above the pulse-obliteration pressure. 
●
Then deflate the cuff at a rate of 2 mmHg per second while listening for the 
Korotkoff sounds.  As the cuff is deflated, turbulent blood flow through the 
brachial artery generates a series of sounds.  Classically, these have been 
described according to five phases.
○
Phase 1 is characterized by a clear, repetitive tapping sound, coinciding 
with reappearance of a palpable pulse.  The initial appearance of Phase 1 
sounds is equal to the systolic blood pressure. 
○
During Phase 2, audible murmurs in the tapping sounds are heard. 
○
In Phases 3 and 4, muted changes in the tapping sounds occur (usually 
within 10 mmHg of the true diastolic pressure) as the pressure 
measurement approaches the diastolic pressure. 
○
Phase 5 is not really a sound; it indicates the disappearance of sounds and 
equates to the diastolic blood pressure.  To ensure that diastole has been 
reached, continue to deflate the cuff pressure for an additional 10 mmHg 
beyond the fifth Korotkoff sound.

Obtain a minimum of two blood-pressure measurements at intervals of at least 1 minute 
and record the average of the measurements as the blood pressure.

patient must have inflammatory articular disease (joint, spine, or entheseal) with 
≥3 points from the following 5 categories:
1.
Evidence of current psoriasis, a personal history of psoriasis, or a family history 
of psoriasis.  Current psoriasis is defined as psoriatic skin or scalp disease 
present today as judged by a rheumatologist or dermatologist.†
A personal history of psoriasis is defined as a history of psoriasis that may be 
obtained from a patient, family physician, dermatologist, rheumatologist, or 
other qualified healthcare provider.  A family history of psoriasis is defined as a 
history of psoriasis in a first- or second-degree relative according to patient 
report.
2.
Typical psoriatic nail dystrophy including onycholysis, pitting, and 
hyperkeratosis observed on current physical examination.
3.
A negative test result for the presence of rheumatoid factor by any method 
except latex but preferably by enzyme-linked immuosorbent assay or 
nephelometry, according to the local laboratory reference range.
4.
Either current dactylitis, defined as swelling of an entire digit, or a history of 
dactylitis recorded by a rheumatologist.  
5.
Radiographic evidence of juxtaarticular new bone formation, appearing as ill 
defined ossification near joint margins (but excluding osteophyte formation) on 
plain radiographs of the hand or foot.
*
The CASPAR criteria have specificity of 98.7% and sensitivity of 91.4%.
†
Current psoriasis is assigned a score of 2; all other features are assigned a score of 1.

PASI SCORE Definitions and Use Psoriasis Area and Severity 
Index (PASI)
The PASI score is an established measure of clinical efficacy for psoriasis medications.24
The PASI is a tool which provides a numeric scoring for subjects overall psoriasis disease 
state, ranging from 0 to 72.  It is a linear combination of percent of surface area of skin 
that is affected and the severity of erythema, infiltration, and desquamation over four body 
regions. 
The endpoints used are based on the percent reduction from baseline, generally 
summarized as a dichotomous outcome based on achieving over an X% reduction (or 
PASI X), where X is 50, 75, 90 and 100.
To calculate the PASI score, the four main body areas are assessed:  head (h), trunk (t), 
upper extremities (u) and lower extremities (l).  These correspond to 10, 30, 20 and 
40% of the total body area respectively.
The area affected by psoriasis within a these four areas site is estimated as a percentage of 
the total area of that anatomic site and assigned a numerical value according to the degree 
of psoriatic involvement as follows:
●
0 = no involvement
●
1 = < 10%
●
2 = 10% to 29%
●
3 = 30% to 49%
●
4 = 50% to 69%
●
5 = 70% to 89%
●
6 = 90% to 100%
The signs of severity, erythema (E), infiltration (I) and desquamation (D) of lesions 
are assessed using a numeric scale 0 – 4 where 0 is a complete lack of cutaneous 
involvement and 4 is the severest possible involvement; scores are made independently

for each of the areas, h, t, u and l and represents a composite score for each area.  The 
signs of severity, erythema (E), induration (I) and desquamation (D) of lesions are 
assessed using a numeric scale 0 – 4:
●
0 = No symptoms
●
1 = Slight
●
2 = Moderate
●
3 = Marked
●
4 = Very marked

indistinct or sloped
2 = moderate

Fine to coarse scale 
covering most of all of the 
lesions
Moderate elevation with 
rough or sloped edges
3 = marked
Very or bright red 
coloration
Coarse, non-tenacious scale 
predominates covering 
most or all of the lesions
Marked elevation typically 
with hard or sharp edges
4 = very marked
Extreme red 
coloration; dusky to 
deep red coloration
Coarse, thick, tenacious 
scale over most or all 
lesions; rough surface
Very marked elevation 
typically with hard sharp 
edges
a.
Do not include residual hyperpigmentation or hypopigmentation as erythema.
Assignments for the following body regions are as follows:
●
Neck:  include with the head
●
Buttocks:  include with the lower extremities
●
Axillae:  include with the trunk
●
Genitals:  include with the trunk
●
The inguinal canal separates the trunk and legs anteriorly

EudraCT 2016-003718-28
103
The PASI score for each body region is obtained by multiplying the sum of the severity 
scores by the area score, then multiplying the result by the constant weighted value 
assigned to that body region.  Since the head, upper extremities, trunk, and lower 
extremities correspond to approximately 10%, 20%, 30%, and 40% of BSA, respectively, 
the PASI score is calculated using the formula.
The PASI score is calculated according to the following formula:
PASI = 0.1(Eh+Ih+Dh)Ah + 0.3(Et+It+Dt)At + 0.2(Eu+Iu+Du)Au + 0.4(El+Il+Dl)Al
where E, I, D, and A denote erythema, induration, desquamation, and area, respectively, 
and h, u, t, and l denote head, upper extremities, trunk, and lower extremities, 
respectively.  PASI scores range from 0.0 to 72.0 with the highest score representing 
complete erythroderma of the severest degree.

Static Physician Global Assessment (sPGA)
This sPGA is a 5 point score ranging from 0 to 4, based on the physician's assessment of 
the average thickness, erythema, and scaling of all psoriatic lesions.39
The assessment is considered "static" which refers to the patients disease state at the time 
of the assessments, without comparison to any of the patient's previous disease states, 
whether at Baseline or at a previous visit.
A lower score indicates less body coverage, with 0 being clear and 1 being almost clear.
The efficacy assessor (or qualified site personnel) scores the erythema, induration and 
scaling of all psoriatic lesions from 0 – 4 based on the following descriptors:
Erythema
0
Normal (post-inflammatory hyper/hypopigmentation may be present)
1
Faint, diffuse pink or slight red coloration
2
Mild (light red coloration)
3
Definite red coloration (Dull to bright red)
4
Bright to Deep red coloration of lesions
Induration (Plaque Elevation)
0
None
1
Just detectable (possible slight elevation above normal skin)
2
Mild thickening (slight but definite elevation, typically edges are indistinct or 
sloped)
3
Clearly distinguishable to moderate thickening (marked definite elevation 
with rough or sloped edges)
4
Severe thickening with hard edges (marked elevation typically with hard or 
sharp edges)

Scaling
0
No scaling
1
Minimal focal scaling (surface dryness with some desquamation)
2
Predominately fine scaling (fine scale partially or mostly covering lesions)
3
Moderate scaling (coarser scale covering most or all of the lesions)
4
Severe/coarse scaling covering almost all or all lesions (coarse, non-
tenacious scale predominates)
Scoring
A composite score is generated from the above data and the final sPGA is determined 
from this composite score as follows:
Clear
0 = 0 for all three
Almost clear
1 = mean > 0, < 1.5
Mild
2 = mean ≥ 1.5, < 2.5
Moderate
3 = mean ≥ 2.5, < 3.5
Severe
4 = mean ≥ 3.5

Palmoplantar Psoriasis Severity Index (PPASI)
The PPASI provides a numeric scoring for psoriasis affecting the hands and feet with 
scores ranging from 0 to 72.  It is a linear combination of percent of surface area of hands 
and feet that are affected and the severity of erythema, induration, and desquamation. 
If a subject has palmoplantar psoriasis, the physician will assess the psoriasis at each 
protocol defined time point.  Both palms and soles on each hand and foot will be 
individually assessed for erythema, induration, desquamation and percentage of area 
affected as follows:
●
Erythema, Induration and Desquamation:
0 = None
1 = Slight
2 = Moderate
3 = Severe
4 = Very Severe
●
Percent of Palm and Sole Area Covered:
0 = Clear
1 = < 10%
2 = 10 – 29%
3 = 30 – 49%
4 = 50 – 69%
5= 70 – 89%
6= 90 – 100%
The PPASI is a composite score and will be computed for each palm and sole, left and 
right and is derived from the sum of the scores for erythema (E), induration (I) and 
desquamation (D) multiplied by the score recorded for the extent of palm and sole area 
involved.  PPASI is calculated as follows:  (sum of scored for E + I + D)*Area 
*0.2(location:  right palm) + (sum of scored for E + I + D)*Area *0.2 (location:  left

Psoriasis Scalp Severity Index (PSSI)
If a subject has scalp psoriasis, the physician will assess the erythema (redness), 
induration (hardness), desquamation (shedding of skin) and percent of scalp covered at 
each protocol defined time point.
Erythema, Induration and Desquamation:
0 = None
1 = Slight
2 = Moderate
3 = Severe
4 = Very Severe
Percent of Scalp Covered:
1 = < 10%
2 = 10 – 29%
3 = 30 – 49%
4 = 50 – 69%
5 = 70 – 89%
6 = 90 – 100%
The PSSI is a composite score derived from the sum of the scores for erythema, 
induration and desquamation multiplied by the score recorded for the extent of scalp area 
involved.  The range is 0 to 72.
