Statistical Methods (Continued):
Pharmacokinetics (PK) and Immunogenicity:
Risankizumab plasma concentrations will be determined.  Descriptive statistics will be calculated for 
each sampling time.  PK and ADA data may be combined with data from other studies and analyzed 
using a mixed-effects modeling approach.  This analysis will estimate the population central value and 
the empirical Bayesian estimates of the individual values for risankizumab apparent clearance (CL/F) 
and volume of distribution (Vss/F).  Additional parameters may be estimated if useful in the 
interpretation of the data.  Relationships between exposure and clinical observations (efficacy or safety 
variables of interest) may be explored.
The number and percentage of subjects with ADA will be calculated.
Safety:
All AEs, SAEs, AEs leading to discontinuation, and pre-specified AEs of special interest will be 
collected during the study.  A treatment-emergent AE (TEAE) is defined as an event with onset or 
worsening after the first study dose of risankizumab and within 15 weeks after the last risankizumab 
injection.  The number and percentages of subjects experiencing TEAE will be tabulated using the 
Medical Dictionary for Drug Regulatory Activities (MedDRA®) system organ class and preferred term.  
Summaries (including percentages and event per 100 subject-years) of SAEs, deaths, AEs leading to 
discontinuation from the study, and pre-specified AEs of special interest will be provided as well.  Mean 
change in laboratory variables, and vital signs variables will be summarized.  For selected parameters, a 
listing of all subjects with clinically significant laboratory values, or vital sign determinations will be 
provided.  Shift tables for changes from baseline according to the normal range will also be provided.
The sample size of this study is not estimated based on powering for any hypothesis testing.  There are 
only approximately 1600 and 40000 Japanese subjects with generalized pustular psoriasis and 
erythrodermic psoriasis respectively, thus finding subjects to participate in the trial will be difficult.  
Therefore, the sample size is determined based on feasibility.  In total, at least 16 subjects will be 
enrolled:  at least 8 subjects for GPP and EP separately.

Introduction
Generalized pustular psoriasis (GPP) is a rare and severe skin disorder that presents with 
flares of widespread sterile pustules on a background of red and tender skin.  It may in 
some cases require subject's hospitalization in intensive burn units and in rare cases be 
fatal.
There is no cure-all treatment for GPP, and as such, the mortality rate is high.
Erythrodermic psoriasis (EP) is a generalised erythema.  It is also a very severe skin 
condition that can be fatal and difficult to treat.  It is marked by widespread involvement 
(> ¾ of the body surface area) with redness and scaling and can be accompanied by 
systemic manifestations such as fever, chills, or malaise.  It can be the first presentation of 
a subject's psoriasis or can result after many years of psoriasis, sometimes as the result of 
a poor control of subject's existing psoriasis.  Erythrodermic psoriasis should be 
distinguished as much as possible from cutaneous manifestation of abrupt systemic 
medication withdrawal or response to malignancy.
Drug Profile
For a more detailed description of the risankizumab profile please refer to the current 
Investigator's Brochure.
Rationale for Performing the Trial
This study will randomize from two subtypes of subjects:  Generalized pustular psoriasis 
(GPP) and erythrodermic psoriasis (EP).
Interleukin (IL)-23 plays a key role in the pathophysiology of psoriasis through induction 
and maintenance of Th-17 type cells that secrete inflammatory cytokines.  Risankizumab 
is a humanized monoclonal antibody (mAB) that specifically neutralizes the IL-23 axis.  
About 10% of subjects with GPP have a preceding history of psoriasis, in which there are 

Risankizumab
M15-988 Protocol Amendment 1
15
persistent, circumscribed, red and scaly plaques.  In considering with action of mechanism 
of risankizumab, this medicine might be effective for GPP and EP.
 
  
 
 
  
 
therefore the aim of this trial is to obtain the efficacy, pharmacokinetic, safety, and 
tolerability data during a 52-week treatment period with two different dose regimens of 
risankizumab in Japanese subjects with GPP or EP.
The current trial is being performed to assess the safety and efficacy of risankizumab to 
support registration in Japan of subjects with GPP or EP.
3.1
Differences Statement
This study is specifically conducted to fulfill a requirement from the Pharmaceuticals and 
Medical Devices Agency (PMDA) in Japan and is focused on the most severe forms of 
psoriasis, for which the medical need is particularly high.
3.2
Benefits and Risks
Participation in this study may help to generate future benefit for larger groups of subjects 
with psoriasis if risankizumab proves to be successful in treating this disease.  In Phase 1 
and Phase 2 studies, risankizumab has been studied in approximately 200 subjects with 
moderate to severe plaque psoriasis.  In these studies, the majority of subjects receiving 
risankizumab achieved 90% improvement of their disease.  The most common adverse 
events (AE) reported in these trials were mild symptoms of the upper respiratory tract, 
including nasal stuffiness, sore throat, and influenza, and headache, that showed no dose 
dependency.  These events were not considered to be related to drug treatment.  Local 

Risankizumab
M15-988 Protocol Amendment 1
16
reactions following subcutaneous administration of risankizumab were uncommon, and 
limited to redness, swelling or induration at the injection site.
As with any immune modulating agent, 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 clinically important active infection will 
not be included in the study.  Subjects with positive QuantiFERON® tuberculosis (TB) 
test or a positive PPD (purified protein derivative) skin test must fulfill entry criteria as 
specified in Section 5.2.2, item 5, prior to receiving risankizumab.  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/serious infection.  Subjects will 
be monitored for signs and symptoms of malignancy at each visit.
Increases in major adverse cardiovascular events (MACE) 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.  
While the likelihood of increased MACE is small, all suspected cardiovascular events 
(serious or non-serious) observed in this study will be adjudicated by an independent 
Cardiac, Cerebrovascular and Thrombotic Events (CCVT) Adjudication Committee.
The subjects will be administrated either 150 mg or 75 mg dose of risankizumab treatment 
during the clinical trial.  From Week 16, subjects will be uptitrated to 150 mg if they have 
not achieved a clinical response.
Although rare, a potential for drug-induced liver injury (DILI) is under constant 
surveillance by sponsors and regulators.  Therefore, this trial 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 is considered appropriate for this stage of clinical 
development.

Investigational Plan
5.1
Overall Study Design and Plan:  Description
This trial is a randomized, open-label study of two different dose regimens of 
risankizumab, 150 mg (2 syringes, 75 mg each) or 75 mg (1 syringe) at Week 0, 4 and 
every 12 weeks in two populations (subjects with GPP and with EP).  Starting after the 
Week 16 visit, subjects on 75 mg may increase dosage to 150 mg.  In total, at least 
16 subjects, 8 with generalized pustular psoriasis and 8 with erythrodermic psoriasis will 
be randomized in this trial.
Subjects are included in the trial once they have signed the informed consent.  Subjects 
suitable after screening will be eligible to participate.

Visit Schedule
All subjects are to adhere to the visit schedule as specified in the Appendix C.  Each visit 
date (with its window) is to be counted from Day 1.  If any visit has to be rescheduled, 
subsequent visits should follow the original visit date schedule.  Additional visits for the 
purpose of re-testing of laboratory parameters or AE monitoring may be included as 
deemed necessary by the investigator.
Details of Trial Procedures at Selected Visits
Study procedures to be performed at each visit are listed in Appendix C and the respective 
protocol sections.  Refer to Section 5.3.1.1 for explanations of procedures.  Additional 
details on procedures at selected visits are provided below.

Measurement of vital signs should precede blood sampling and be assessed pre-dose at all 
dosing visits.
Patient reported outcomes (PRO)s should be completed by the subject on his/her own 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.  At Visit 2 these 
questionnaires should be obtained before having the subject randomized.
Screening and Run-In Period(s)
No trial procedures should be done until the subject has consented to taking part in the 
trial.
Once consented, the subject is considered to be enrolled in the trial and has started 
screening.  The subject number should be recorded on the enrollment log and registered in 
the Interactive Response System (IRT) as a screened subject.
The Screening Period (Visit 1) is from Day –42 to Day –1.  Visit 1 procedures may be 
extended to two physical visits, if needed.  Re-screening will be permitted.
Subjects that initially screen-fail for the study may be permitted to re-screen one time 
following re-consent and:
●
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 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 5.2.2 and 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-

Risankizumab
M15-988 Protocol Amendment 1
20
screening within the 42 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.
Infection Screening
Refer to exclusion criteria Section 5.2.2 with study participation directive for subjects 
with a positive result for PPD or QuantiFERON® for TB, Hepatitis B, Hepatitis C, and 
Human Immunodeficiency Virus (HIV).
Medical History:
Cardiovascular and risk factors will be collected and reported in the Medical History 
electronic case report form (eCRF) page.
Baseline Conditions
Chronic diseases, current observable conditions, any new clinically relevant findings 
discovered from the physical examination, electrocardiogram (ECG), safety laboratory 
tests, and any condition requiring therapy (excluding psoriasis) will be reported on the 
Baseline Condition eCRF Page.
History of Psoriatic Arthritis
At Visit 1, all subjects at all sites will be evaluated via CASPAr (ClASsification of 
Psoriatic Arthritis) criteria for history of psoriatic arthritis.
Interactive Response System (IRT)
All subjects who are screened must be registered with IRT.  If the subject must be 
designated as a screen failure, IRT should be notified as soon as possible and within the 
Screening Period.  Details of IRT procedures can be found in the IRT manual located in 
the Investigator Site File (ISF).

M15-988 Protocol Amendment 1
21
For the comprehensive list of the trial procedures required at the Screening Visit (Visit 1) 
please refer to Appendix C.
Treatment Period(s)
The treatment period is from Visit 2 to EOT (End of Treatment) Visit.
Visits 2, 4, 6, 8, 10, 12, 16, 20, end of treatment (EOT), Week 184 follow-up visit and 
Week 188 follow-up visit will be performed in fasted state (8 hours no food and only 
water).  If a subject comes in non-fasted where a fasting condition is required, the visit 
should be performed, the non-fasted condition documented on the laboratory requisition, 
and the subject reminded about the expected conditions.  At Visits 3, 5, 7, 9, 11, 13, 14, 
15, 17, 18, 19, 21, only white blood cell count (WBC), serum C-reactive protein (CRP) 
and serum albumin ("targeted" lab) will be collected and fasting is not required for these 
labs.
Urine pregnancy testing for all woman of child-bearing potential will be conducted on-site 
prior to every dosing and must be negative to further treat the subject.  A positive urine 
test must be confirmed with a serum pregnancy test.
Randomization via IRT and administration of study medication should be the last activity 
at Visit 2.
Venipuncture (i.e., safety laboratories, PK, anti-drug antibody [ADA]), should be the last 
procedure prior to study drug administration.
Follow Up Period and Trial Completion
For all randomized subjects termination of trial medication and trial completion must be 
recorded on the corresponding eCRFs.
Early Treatment and Trial Termination 
Subjects who prematurely discontinue (PD) treatment prior to the planned Appendix C
visit schedule will complete EOT visit procedures instead of the planned treatment period 

Risankizumab
M15-988 Protocol Amendment 1
22
visit.  If study medication is discontinued, every effort should be made to have the subject 
continue in the trial and complete all of the follow remaining trial and follow up visits.  If 
a subject cannot or will not continue in the trial, these subjects should be registered as 
withdrawn/discontinued in IRT.  These subjects should be registered as withdrawn in IRT 
and return to the clinic for Week 188 Follow-Up visit 16 weeks after last dose of study 
medication.
Trial Completion
Subjects who finish the randomized treatment period will return to the clinic for 
Week 184 Follow-Up Visit and Week 188 Follow-Up Visit.  Completion is defined as a 
subject having completed the Week 188 Follow-Up visit.

5.3
Efficacy, Pharmacokinetic 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
Informed Consent
The subject will sign and date a study specific, Independent Ethics Committee 
(IEC)/Independent 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 both the Screening and the Week 0 visit.
Demographics
The subject's demographic data, including date of birth, gender, race, ethnicity, and 
disease status will be collected at the Screening Visit.
Physical Examination
Complete and targeted physical examinations will be performed at visits as described in 
Appendix C.  Complete physical examination will include general appearance as well as 

Risankizumab
M15-988 Protocol Amendment 1
30
evaluation of all relevant organ systems.  Targeted physical examination will include vital 
signs assessment and evaluation of organ systems associated with AE(s) symptoms or 
laboratory abnormalities.
Physical examination findings that are related to subject's medical history will be captured 
on the appropriate medical history eCRF.
Vital Signs
Vital sign assessment includes temperature, pulse rate, sitting blood pressure, and 
respiratory rate, after subjects have been seated comfortably for at least 5 minutes.
Measurement of vital signs should precede blood sampling and be assessed pre-dose at all 
dosing visits.  At Visit 2 and Visit 3 additional vital signs will be taken at 5 minutes 
post-dose and 60 minutes post-dose.
Subjects should be closely monitored for signs and symptoms of hypersensitivity 
reactions for approximately 2 hours after the first dose administered and 1 hour following 
all other doses of study drug.  Hypersensitivity reactions should be treated according to 
medical standards.  Pre-medications for further injections might be considered and will be 
agreed on between investigator and AbbVie TA MD.
Body Weight and Waist Circumference
Waist circumference measurements should be made around a subject's bare midriff, after 
the subject exhales while standing without shoes and with both feet touching and arms 
hanging freely.  The tape should be placed perpendicular to the long axis of the body and 
horizontal to the floor and applied with sufficient tension to conform to the measurement 
surface.  Waist circumference should be determined by measuring the midpoint between 
the lowest rib and the iliac crest.
Body weight measurements should be done on the same scale for each subject.  In order to 
get comparable body weight values, it should be performed in the following way:

Risankizumab
M15-988 Protocol Amendment 1
31
●
fasting (except for the Screening Visit)
●
after the urine sampling (body weight after bladder voiding)
●
shoes and coat/jackets should be taken off
●
pockets should be emptied of heavy objects (i.e., keys, coins, etc.)
Electrocardiogram
The 12-lead ECGs will be performed as scheduled in Appendix C.
The ECG 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.
The ECG may be repeated for quality reasons and the repeat used for analysis.  Additional 
ECGs may be collected for safety reasons.  Clinically relevant, abnormal findings will be 
reported as AEs.
Information about the details of ECG collection and the parameters assessed will be 
provided in the ISF.
The electronic version of the ECG is regarded as source data.
Pregnancy Testing
A serum pregnancy test will be performed for all female subjects at the Screening Visit.  
A urine pregnancy testing will be done on all women of child-bearing potential prior to 
administration of study drug at all dosing visits and at each Follow-Up Visit.  Additional 
serum pregnancy testing will occur in case of a positive urine test result at any of the visits 
and must be negative to further treat the subject.
Females of non-childbearing potential (either postmenopausal or permanently surgically 
sterile as defined in Section 5.2.4) do not require pregnancy testing after screening.

Risankizumab
M15-988 Protocol Amendment 1

Safety Laboratory Parameters
The laboratory tests listed in Table 2 will be performed by the central laboratory service 
provider at Visits 1, 2, 4, 6, 8, 10, 12, 16, 20, EOT and at Week 188 follow-up visit 
("complete" lab).  At Visits 3, 5, 7, 9, 11, 13, 14, 15, 17, 18, 19, 21, only WBC, serum 
CRP and serum albumin will be collected ("targeted" lab).  A local laboratory may be 
used for selected tests in exceptional cases.  Subjects should be fasting for at least 8 hours 
prior to the blood sample being taken at the "complete" visits, except for screening (see 
Appendix C).
Instructions regarding sample collection, sample handling/processing and sample shipping 
are provided in the Laboratory Manual in the ISF.  For time points of laboratory sampling, 
see Appendix C.
Laboratory results (i.e., all safety laboratory and clinical laboratory data relevant for 
current clinical practice) of the subjects will be available in real time to the respective 
investigator (via laboratory reports) and to the sponsor (via the central laboratory website) 
and selected abnormal laboratory alerts will be flagged to the site and sent to sponsor in 
real time.
A clinically relevant value may be either in or outside the reference range.  Clinically 
relevant abnormal laboratory test results must be confirmed using an unscheduled visit 
laboratory kit and should be repeated until normalization or stabilization or until an 
alternative explanation has been found.  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 adverse events.

36
scheduled study activities except for ECG, vital signs, and dosing.  Blood samples for the 
PK assay should be collected as closely as possible relative to the time of dosing and 
within 60 minutes prior to dosing.  Date and exact time (to the nearest minute) of drug 
administration will be recorded on eCRFs.
Eleven samples will be collected per subject for pharmacokinetic analysis during the 
treatment and follow-up periods.
Blood Samples for Risankizumab Anti-Drug Antibody (ADA) Assay:
Blood samples, approximately 3 mL, for risankizumab ADA assay will be collected at the 
study visits at the time points specified in Appendix C.  Blood samples for the ADA assay 
should be collected as closely as possible relative to the time of dosing and within 
60 minutes prior to dosing.  Date and exact time (to the nearest minute) of drug 
administration will be recorded on eCRFs.
Eleven samples will be collected per subject for ADA analysis during the treatment and 
follow-up periods.
After completion of the study, PK and ADA plasma samples may be used for further 
methodological investigations, e.g., stability testing.
5.3.2.2
Handling/Processing of Samples
Details for the handling and processing of the samples will be provided outside this 
protocol, in the laboratory manual.
5.3.2.3
Disposition of Samples
The frozen plasma samples for risankizumab and risankizumab ADA assays will be

5.3.2.4
Measurement Methods
Plasma concentrations of risankizumab and relative titers of risankizumab ADA will be 
determined using validated methods under the supervision of the Bioanalysis department 
at AbbVie.  Any additional analytes may be analyzed using non-validated methods.  
Plasma samples collected for risankizumab and risankizumab ADA analysis may be used 
for future assay development or validation activities.
The presence of ADA to risankizumab will be assessed via a tiered approach using a 
validated electrochemiluminescence assay (screening, confirmatory, and titration analysis 
as appropriate).  Samples that are confirmed positive may be further characterized in a 
validated neutralizing antibody (NAb) assay.

Pharmacokinetic Variables
Risankizumab plasma concentrations will be determined.  Descriptive statistics will be 
calculated for each sampling time.  PK and ADA data may be combined with data from 
other studies and analyzed using a mixed-effects modeling approach.  This analysis will 
estimate the population central value and the empirical Bayesian estimates of the 
individual values for risankizumab apparent clearance (CL/F) and volume of distribution 
(Vss/F).  Additional parameters may be estimated if useful in the interpretation of the 
data.  Relationships between exposure and clinical observations (efficacy or safety 
variables of interest) may be explored.
The number and percentage of subjects with ADA will be calculated.  As appropriate, the 
effect of ADA on risankizumab pharmacokinetics and efficacy may be explored.

5.4
Removal of Subjects from Therapy or Assessment
5.4.1
Discontinuation of Individual Subjects
All subjects have the right to withdraw from the study at any time without the need to 
justify their decision.  The investigator has the right to remove subjects from the study for 
noncompliance, administrative or other reasons.  It should be clearly understood that an 
excessive rate of withdrawals can render the study results uninterpretable.  The sponsor 
reserves the right to remove any study subject from the trial for non-compliance.
An individual subject is to be withdrawn from trial treatment if:
●
The subject withdraws consent for trial treatment or trial participation, without 
the need to justify the decision.
●
The subject can no longer be treated with trial medication for other medical 
reasons (such as surgery, adverse events, other diseases, or pregnancy)
●
Development of a toxicity or adverse event which warrants risankizumab 
discontinuation including but not limited to SAEs or Suspected Unexpected 
Serious Adverse Reactions (SUSAR)s.
●
If prohibited treatment is used during the study for any indication, the subject 
must discontinue use of the prohibited treatment if he/she wishes to continue in 
the study.  In case of undue safety risk for the subject, the subject should 
discontinue study treatment at the discretion of the investigator.  If the subject 
received a live virus vaccination during the study, the subject must discontinue 
study treatment
●
If a subject experiences an intolerable increase of psoriasis during the course 
of the trial the subject will be discontinued from the trial to receive rescue 
treatment as deemed appropriate by the investigator
●
The subject has repeatedly shown to be non-compliant with important trial 
procedures and, in the opinion of the investigator, is not willing or able to stick 
to the trial requirements in the future.
Discontinuation of study medication should not lead to withdrawal from the study.  If 
possible the subject should complete all study visits and procedures as initially planned.

Risankizumab
M15-988 Protocol Amendment 1
42
Given the subject's agreement, the subject will undergo the procedures for premature 
discontinuation and follow up as outlined in Appendix C.  If a subject becomes pregnant, 
refer to Section 6.1.6 for instructions on treatment termination.
For all subjects the reason for withdrawal (e.g., AE) must be recorded in the eCRF.  These 
data will be included in the trial database and reported.
5.4.2
Discontinuation of Entire Study
AbbVie may terminate this study prematurely, either in its entirety or at any study site, for 
reasonable cause provided that written notice is submitted in advance of the intended 
termination.  The investigator may also terminate the study at his/her site for reasonable 
cause, after providing written notice to AbbVie in advance of the intended termination.  
Advance notice is not required by either party if the study is stopped due to safety 
concerns.  If AbbVie terminates the study for safety reasons, AbbVie will immediately 
notify the investigator by telephone and subsequently provide written instructions for 
study termination.

5.5.3
Method of Assigning Subjects to Treatment Groups
Within each substudy, subjects will be randomized to receive risankizumab 75 mg or 
risankizumab 150 mg in a ratio of 1:1.
After the eligibility criteria are confirmed, the investigator or designee will randomize the 
subject on Day 1 (Visit 2) through IRT call or website entry.  At visits where study 
medication is to be administered, study sites will be required to complete the medication 
resupply module in the IRT.
5.5.4
Selection and Timing of Dose for Each Subject
An IRT will be used to allocate medication to subjects through medication numbers.  At 
visits where study medication is to be administered, study sites will be required to 
complete the medication resupply module in the IRT.  These visits are specified in 
Appendix C.
At randomization as well as subsequent medication administration visits, IRT will assign 
medication numbers.  At visits after Week 16, subjects in the 75 mg arm who do not 
achieve GPP or EP Clinical Response may be uptitrated to receive 150 mg; this process 
will be managed through IRT.  Site personnel will enter the kit numbers in the eCRF.
Study drugs will be administered subcutaneously.  Injections will be given with each 
subject receiving 1 or 2 injections of risankizumab at each dosing visit.  Syringes will be 
administered per Appendix C schedule as assigned by IRT.
Risankizumab will be administered as a subcutaneous injection in the abdomen, thighs, 
gluteal regions, or upper arms (contra-lateral to that used for PK/ADA samples).  
Injections 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.

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.
5.5.7
Drug Accountability
The Investigator/Pharmacist/investigational drug storage manager will receive the 
investigational drugs delivered by the sponsor when the following requirements are 
fulfilled:
●
Approval of the trial protocol by the IRB
●
Availability of a signed and dated clinical trial contract between the sponsor 
and the head of the investigational site,
●
Notification of the regulatory authority, e.g., competent authority,
●
Availability of the curriculum vitae of the principal Investigator,
●
Availability of a signed and dated clinical trial protocol
●
Availability of the proof of a medical license for the principal Investigator 
The investigator/pharmacist who is documented in the trial staff list/investigational drug 
storage manager must maintain records of the product's delivery to the trial site, the 
inventory at the site, the use by each subject, and the return to the sponsor or 
warehouse/drug distribution centre or alternative disposal of unused products.  If 
applicable, the sponsor or warehouse/drug distribution centre will maintain records of the 
disposal.

Risankizumab
M15-988 Protocol Amendment 1

These records will include dates, quantities, batch/serial numbers, expiry ('use-by') dates, 
and the unique code numbers assigned to the investigational product and trial subjects.  
The investigator/pharmacist who is documented in the trial staff list/investigational drug 
storage manager will maintain records that document adequately that the subjects were 
provided the doses specified by the protocol and reconcile all investigational products 
received from the sponsor.  At the time of return to the sponsor the 
investigator/pharmacist who is documented in the trial staff list/investigational drug 
storage manager must verify that all unused or partially used drug supplies are in the 
Investigator's possession.
All unused medication must be returned to the Sponsor.
5.6
Discussion and Justification of Study Design
5.6.1
Discussion of Study Design and Choice of Control Groups
This is a randomized, open-label, parallel design trial.  The trial design is appropriate for 
assessing the safety and efficacy of two different doses risankizumab for Japanese 
subjects with generalized pustular psoriasis or erythrodermic psoriasis.  Since the 
population of subjects, especially GPP subjects, is very small, it is not feasible to have a 
control group.  In addition to 150 mg, a 75 mg dose was also selected for this study to 
provide dose response information as well as evaluation of efficacy at a lower dose in 
Japanese subjects.
5.6.2
Appropriateness of Measurements
All measurements performed during this trial are standard measurements in GPP and/or 
EP treatment trials and will be performed in order to monitor safety aspects or assess 
treatment response in an appropriate way.  Therefore, the appropriateness of all 
measurements applied in this trial is given.

Risankizumab
M15-988 Protocol Amendment 1
47
5.6.3
Suitability of Subject Population
The subjects enrolled in the present study are subjects with GPP or EP, in agreement with 
the indication that is being pursued.
The inclusion and exclusion criteria, for most of them limit the factors of variability that 
could confuse efficacy and safety outcomes and/or have the purpose of protecting 
subject's safety.
Any active ongoing inflammatory disease other than GPP or EP that might confound 
efficacy evaluation according to investigator's judgment is exclusionary, as well as the 
intake of psoriasis medications that may interfere with risankizumab in the evaluation of 
the psoriatic disease.
GPP is a potentially severe disease and EP may lead to dehydration.  Both diseases may 
be fatal.  In order to protect subject's safety and control, medical conditions that could, in 
the opinion of the investigator, compromise the safety of the subjects are exclusionary.  
This is also the case for the exclusion criteria relating to GPP and EP. 
Moreover, the restriction of the subject population will facilitate the interpretation of 
safety results.
5.6.4
Selection of Doses in the Study
A dose of 150 mg has been selected for global Phase 3 trials of risankizumab for psoriasis.  
The dose selection strategy for global Phase 3 involved analyses of data from the 
completed Phase 1 study (Trial 1311.1, c02434648), the Phase 2 study (Trial 1311.2, 
c03272682) and PK-Pharmacodynamic analysis of all available data from the Phase 1 and 
2 studies.  In Study 1311.16, following single dose administration of risankizumab 18 mg 
to 300 mg SC doses,
 
 
 
 in the 

Risankizumab
M15-988 Protocol Amendment 1
48
Phase 2 study (Trial 1311.2).  Therefore, the dose of 150 mg was selected in this trial, 
which is the same dose as being evaluated in other global Phase 3 trials of risankizumab 
for psoriasis.
In the Phase 2 study (Trial 1311.2), risankizumab 90 mg dose showed about 10% lower 
PASI90 response rate compared to the 180 mg dose.  In addition to 150 mg, a 75 mg dose 
was also selected for this study to provide dose response information as well as evaluation 
of efficacy at a lower dose in Japanese subjects.  The 75 mg dose in Japanese subjects is 
expected to provide risankizumab exposures comparable to the 90 mg dose evaluated in 
the Phase 2 study (Trial 1311.2) in Western subjects.

Complaints
A Complaint is any written, electronic, or oral communication that alleges deficiencies 
related to the physical characteristics, identity, quality, purity, potency, durability, 
reliability, safety, effectiveness, or performance of a product/device after it is released for 
distribution.
The investigational product in this trial contains both:
●
Biologic compound(s) and
●
Device component(s) (pre-filled syringe).
Complaints associated with any component of this investigational product must be 
reported to the Sponsor (Section 6.2.2).  For adverse events, please refer to Sections 6.1
through 6.1.6.  For product complaints, please refer to Section 6.2.
6.1
Medical Complaints
The investigator will monitor each subject for clinical and laboratory evidence of adverse 
events on a routine basis throughout the study.  The investigator will assess and record 
any adverse event in detail including the date of onset, event diagnosis (if known) or 
sign/symptom, severity, time course (end date, ongoing, intermittent), relationship of the 

Risankizumab
M15-988 Protocol Amendment 1
49
adverse event to study drug, and any action(s) taken.  For SAEs considered as having "no 
reasonable possibility" of being associated with study drug, the investigator will provide 
an Other cause of the event.  For adverse events to be considered 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 subject 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 as a 
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.
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.

Risankizumab
M15-988 Protocol Amendment 1
51
For SAEs with the outcome of death, the date and cause of death will be recorded on the 
appropriate case report form.
6.1.1.3
Adverse Events of Special Interest
The term adverse events of special interest (AESI) relates to any specific AE that has been 
identified at the compound level as being of particular concern for prospective safety 
monitoring and safety assessment within this trial, e.g., the potential for AEs based on 
knowledge from other compounds in the same class.  Ongoing evaluation of adverse 
events may identify future AESI.
The following are considered as AESI:
Hepatic Injury
A hepatic injury is defined by the following alterations of hepatic laboratory parameters:
●
an elevation of aspartate aminotransferase (AST) and/or alanine 
aminotransferase (ALT) > 3-fold upper limit of normal (ULN combined with 
an elevation of total bilirubin > 2-fold ULN measured in the same blood draw 
sample, and/or
●
marked peak aminotransferase (ALT, and/or AST) elevations ≥ 10-fold ULN.
These lab findings constitute a hepatic injury alert and the subjects showing these lab 
abnormalities need to be followed up according to instructions from the sponsor including 
completion of the hepatic adverse events form.
In case of clinical symptoms of hepatic injury (icterus, unexplained encephalopathy, 
unexplained coagulopathy, right upper quadrant abdominal pain, etc.) without lab results 
(ALT, AST, total bilirubin) available, the investigator should make sure these parameters 
are analysed, if necessary with an unscheduled blood test.  Should the results meet the 
criteria of hepatic injury alert, investigators are advised to provide a hepatic workup as 
directed by the Sponsor.

Adverse Event Severity
Intensity of AEs
The intensity grading of AEs will be performed according to Rheumatology Common 
Toxicity Criteria (RCTC) Version 2.0 developed by OMERACT.  Refer to the ISF for 
intensity/severity classification.
Intensity options are:
Grade 1
mild
Grade 2
moderate
Grade 3
severe
Grade 4
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
An adverse event where there is evidence to suggest a causal 
relationship between the study drug and the adverse event.
No Reasonable 
Possibility
An adverse event where there is no evidence to suggest a causal 
relationship between the study drug and the adverse event.
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.

Risankizumab
M15-988 Protocol Amendment 1
53
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 AEs reported from the time of study drug administration until 16 weeks following 
discontinuation of study drug administration have elapsed will be collected, whether 
solicited or spontaneously reported by the subject.  In addition, SAEs and protocol-related 
non-serious adverse events will be collected from the time the subject signed the study-
specific informed consent.

Adverse Event Reporting
In the event of a serious adverse event, whether associated with study drug or not, the 
Investigator will notify Clinical Pharmacovigilance within 24 hours of the site being made 
aware of the serious adverse event by entering the serious adverse event data into the 
electronic data capture (EDC) system.  SAEs that occur prior to the site having access to 
the RAVE® system, or if RAVE is not operable, should be documented on the SAE Non-
Case Report Forms (CRF) and emailed (preferred route) or faxed to Clinical

Product Complaint
6.2.1
Definition
A Product Complaint is any Complaint (see Section 6.0 for the definition) related to the 
biologic or drug component of the product or to the medical device component(s).
For a product this may include, but is not limited to, damaged/broken product or 
packaging, product appearance whose color/markings do not match the labeling, labeling 
discrepancies/inadequacies in the labeling/instructions (example:  printing illegible), 
missing components/product, device not working properly, or packaging issues.
For medical devices, a product complaint also includes all deaths of a subject 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
8.1
Statistical and Analytical Plans
The objective of this study is to assess the long term safety and efficacy of two different 
dose regimens of risankizumab for Japanese subjects with generalized pustular psoriasis 
or erythrodermic psoriasis. 
There are two substudies.  Substudy GPP will include subjects with GPP, and Substudy 
EP will include subjects with EP.

Risankizumab
M15-988 Protocol Amendment 1
59
The primary endpoint for Substudy GPP is the proportion of subjects achieving a GPP 
Clinical Response, defined as at least "Slightly Improved" in the overall improvement 
rating from baseline, at Week 16, according to JDA total score for GPP.
The primary endpoint for Substudy EP is the proportion of subjects achieving an EP 
Clinical Response, defined as at least "Minimally Improved" in CGI-GI for EP at 
Week 16.
The summary tables will be presented separately for each Substudy and each 
risankizumab dose regimen.  Integration across two doses for efficacy and safety within 
each study, and integration across the two Substudies for safety will be provided when 
appropriate.
Complete, specific details of the statistical analysis will be described and fully 
documented in the Statistical Analysis Plan (SAP).  The SAP will be finalized prior to the 
database lock.
8.1.1
Analysis Population
The Intent-to-Treat (ITT) subject population in each Substudy is defined as all 
randomized subjects with at least one dose of study drug.  The Safety population is the 
same as the ITT population.
8.1.2
Null and Alternative Hypotheses
Not applicable.
8.1.3
Planned Analyses
No formal hypothesis testing is planned for this trial.
The analysis will be performed using SAS® (SAS Institute Inc., Cary, NC, USA).

8.1.3.1
Demographics and Baseline Characteristics
Demographics and Baseline characteristics of the study subjects will be summarized for 
each arm of each Substudy and overall using descriptive statistics.
8.1.4
Primary Endpoint Analyses
For each Substudy and dose, the primary efficacy endpoint per Section 5.3.3 will be 
summarized descriptively, with count and proportion.
8.1.5
Secondary Endpoint Analyses
For each Substudy, descriptive statistics for secondary endpoints will be provided.  These 
include the number of observations, min/max, range, median, 25th percentile, 
75th percentile, median, mean, and standard deviation for continuous variables and counts 
and percentages for discrete variables.
8.1.6
Safety Analyses
Adverse events will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA®) coding dictionary.  Standard AbbVie summary tables and listings will be 
produced.
All AEs, SAEs, AEs leading to discontinuation, and pre-specified AEs of special interest 
will be collected during the study.  A treatment-emergent AE (TEAE) is defined as an 
event with onset or worsening after the first study dose of risankizumab and within 
15 weeks (105 days) after the last risankizumab injection.  The number and percentages of 
subjects experiencing TEAE will be tabulated using the MedDRA system organ class and 
preferred term.  Summaries (including percentages and event per 100 subject-years) of 
SAEs, deaths, AEs leading to discontinuation from the study, and pre-specified AEs of 
special interest will be provided as well.  Mean change in laboratory variables, and vital 
signs determinations will be summarized.  For selected parameters, a listing of all subjects 
with clinically significant laboratory values and vital sign determinations will be 

Risankizumab
M15-988 Protocol Amendment 1
61
provided.  Shift tables for changes from baseline according to the normal range will also 
be provided.
8.1.7
Pharmacokinetic and Exposure-Response Analysis
Individual risankizumab plasma 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.
Data from this study may be combined with data from other risankizumab studies for the 
population pharmacokinetic and exposure-response analyses or for external evaluation of 
pharmacokinetic or exposure-response models developed from other studies.  Population 
pharmacokinetic and exposure-response analyses of only data from this study may not be 
conducted.  The following general methodology will be used for the population 
pharmacokinetic analysis.  Population pharmacokinetic analyses of risankizumab will be 
performed using 
.  Pharmacokinetic models will 
be built using a non-linear mixed-effects modeling approach with NONMEM software 
(Version 7, or a higher version).  The structure of the starting pharmacokinetic model will 
be based on the pharmacokinetic analysis data from previous studies.  Apparent CL/F and 
apparent Vss/F of risankizumab will be the pharmacokinetic parameters of major interest 
in the NONMEM analyses.  If necessary, other parameters, including the parameters 
describing absorption characteristics, may be estimated if useful in the analysis.
Once an appropriate base pharmacokinetic model 
 
 is developed, 
 
  The 
relationship between

 or another suitable 
regression/smoothing method at a significance

As appropriate, the effect of 
 on 
 as well 
as the relationships between exposure and clinical observations
 
may be explored.  Results of the PK and exposure-response analyses 
may be summarized in a separate report rather than in the clinical study report.
8.1.8
Interim Analyses
An interim analysis will be conducted when the last subject completes the Week 28 visit 
and all data pertaining to Week 28 and earlier are cleaned.  For this analysis all Week 16 
efficacy endpoints will be analysed, and all safety as well as pharmacokinetic and anti-
immunogenicity data received by cut-off date will be analysed.  Another interim analysis 
will be conducted when the last subject completes the Week 52 visit.  The analyses will be 
performed for the efficacy endpoints until Week 52, as well as all safety and 
pharmacokinetic and immunogenicity data received by cut-off date.
Additional interim analysis may be performed if deemed necessary for regulatory 
purpose.
8.1.9
Handling of Missing Data
Every effort should be made to collect complete data at all visits.
In addition to the as-observed analysis, the following rules will be used to impute for 
missing data:
●
For continuous endpoints, LOCF (Last Observation Carried Forward) will be 
used to impute missing values
●
For all binary endpoints (i.e., endpoints that are either 1 (subject responded) or 
0 (subject did not respond):

Risankizumab
M15-988 Protocol Amendment 1
63
○
If no assessment after that visit*, then impute as failure (NRI [No 
Response Imputation])
○
If there are assessments at visits* before and after, only impute as success 
if both visits are successes; else impute as failure
*
Subjects that take prohibited medications to treat Psoriasis will be treated the same as those that discontinued from 
the trial – i.e., subsequent visits following start of prohibited medication will be considered as failure for binary 
endpoints.
8.2
Determination of Sample Size
The sample size is not estimated based on powering for any hypothesis testing.  There are 
only approximately 1600 and 40000 Japanese subjects with generalized pustular psoriasis 
and erythrodermic psoriasis respectively, thus finding subjects to participate in the trial 
will be difficult.  Therefore, the sample size is determined based on feasibility.  In total, at 
least 16 subjects will be enrolled:  at least 8 subjects for GPP and EP separately.
8.3
Randomization Methods
An IRT will be used to determine the randomization of subjects.  Detailed instructions for 
using the IRT will be provided to the site personnel.  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 fashion in each group to either 150 mg (2 syringes, 75 mg 
each) or 75 mg (1 syringe) at Week 0, 4 and every 12 weeks.  The randomization schedule 
will be prepared by the Statistics Department of AbbVie and provided to drug supply for 
adequate packaging.  Randomization will be done using an adequate block size.

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(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 
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 

Risankizumab
M15-988 Protocol Amendment 1
67
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.
11.0
Data Quality Assurance
Computer logic and manual checks will be created to identify items such as inconsistent 
study dates.  Any necessary corrections will be made to the eCRF.
12.0
Use of Information
Any research that may be done using optional exploratory research samples from this
study will be experimental in nature and the results will not be suitable for clinical 
decision making or subject management.  Hence, the subject will not be informed of 
individual results, should analyses be performed, nor will anyone not directly involved in 
this research.  Correspondingly, researchers will have no access to subject identifiers.  
Individual results will not be reported to anyone not directly involved in this research 
other than for regulatory purposes.  Aggregate data from optional exploratory research 
may be provided to investigators and used in scientific publications or presented at 
medical conventions.  Optional exploratory research information will be published or 
presented only in a way that does not identify any individual subject.
13.0

Psoriasis Area and Severity Index (PASI)
The PASI score is an established measure of clinical efficacy for psoriasis medications 
(Study R96-3541).
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 < 30%
●
3 = 30% to < 50%
●
4 = 50% to < 70%
●
5 = 70% to < 90%
●
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 

Risankizumab
M15-988 Protocol Amendment 1
81
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
The table below outlines the characteristics of each category.
Erythemaa
Desquamation
Induration
0 = none
No redness
No scaling
No elevation over normal 
skin
1 = slight
Faint redness

2 = moderate

rough or sloped edges
3 = marked
Very or bright red

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

Risankizumab
M15-988 Protocol Amendment 1
82
●
The inguinal canal separates the trunk and legs anteriorly
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.

Diagnosis and Assessments for Subjects with Psoriatic Arthritis
At Visit 1, subjects with a positive history of PsA or suspected to have PsA will be further 
evaluated for PsA diagnosis based on CASPAr (ClASsification of Psoriatic Arthritis) 
criteria (Study R15-1001).  To be classified has having PsA, a subject must have 
inflammatory articular disease (joint, spine, or entheseal) with at least 3 points total from 
the 5 categories below.  All trial participants will have 2 points assigned due to evidence 
of current psoriasis per trial entry criteria and require at least one additional point for 
diagnosis of PsA.

Patient Reported Outcomes
Dermatology Life Quality Index
The DLQI is a subject-administered, ten-question, quality of life questionnaire that covers 
six domains including symptoms and feelings, daily activities, leisure, work and school, 
personal relationships and treatment (Study R05-2548).  The DLQI has a 1-week recall 
period.  Item scores range from 0 (not relevant) and 1 (not at all) to 3 (very much).  
Question 7 is a "yes"/"no" question where "yes" is scored as 3. 
The DLQI will be self-administered by the subject at visits indicated in the Appendix C.
The DLQI will be analyzed under six headings as follows:
Domain 
Question Number 
Score
Symptoms and feelings
Questions 1 and 2
Score maximum 6
Daily activities
Questions 3 and 4

Questions 5 and 6
Score maximum 6
Work and school
Question 7
Score maximum 3
Personal relationships
Questions 8 and 9
Score maximum 6
Treatment
Question 10
Score maximum 3
DLQI total score is calculated by summing the scores of each question resulting in a range 
of 0 to 30 where 0 – 1 = no effect on subject's life, 2 – 5 = small effect, 6 – 10 = moderate 
effect, 11 – 20 = very large effect, and 21 – 30 = extremely large effect on subject's life.  
The higher the score, the more the quality of life is impaired.  A 5-point change from 
baseline is considered a clinically important difference.
If the answer to one question in a domain is missing, that domain is treated as missing.  If 
2 or more questions are left unanswered (missing), DLQI total score is treated as missing.

PGA Scale for Generalized Pustular Psoriasis
The Physician's Global Assessment of Generalized Pustular Psoriasis is a 6-point scale 
used to measure the severity of skin disease at the time of the qualified investigator's 
evaluation of the subject.  The degree of overall severity will be evaluated using the 
following categories:  erythema, pustulation, and edema.
Scoring Instructions:
If a subject has signs of erythema, pustulation, or edema intermediate between two grades, 
then the subject's erythema, pustulation, or edema grade should be assigned the higher of 
the two grades.  For example, if a subject's erythema is considered to be worse than 'mild' 
but less than 'moderate,' the subject's erythema grade should be considered 'moderate.'
The subject's score is an arithmetic average (mean) of the grades for erythema, 
pustulation, and edema, rounded to the nearest whole integer.  For example, if a subject's 
erythema is moderate (3), pustulation is mild (2), and edema is moderate (3), the average 
grade is 2.67, which is rounded to the nearest whole integer of 3, giving the subject a 
score of 'moderate.'
