2 INTRODUCTION
2.1 Background and Rationale
Why Is This Study Being Conducted
Risankizumab is a fully humanized monoclonal antibody (mAb) of the immunoglobin G1 subclass 
directed towards interleukin (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.
Positive results were observed from 4 pivotal Phase 3 clinical trials that evaluated risankizumab 
compared with ustekinumab, placebo, and adalimumab for the treatment of patients with moderate to 
severe plaque psoriasis.  Results from these pivotal studies demonstrated that risankizumab is highly 
effective for the treatment of psoriasis, meeting co-primary endpoints of achieving at least a 90% 
improvement in the Psoriasis Area and Severity Index (PASI 90) and static physician global assessment 
(sPGA) score of clear or almost clear (0 or 1) versus comparator or placebo at Week 16 across all 
4 studies.1
In the pivotal Phase 3 clinical trials, the risankizumab 150-mg dose was administered with a 90-mg/mL 
formulation via 2 subcutaneous (SC) 75-mg injections.  To deliver a more patient-friendly experience, a 
new formulation was developed at 150 mg/mL that will enable delivery of the 150 mg dose with one SC 
injection.  This study will evaluate the risankizumab 150-mg/mL formulation self-administered by AI 
using the same dosing regimen of risankizumab (150 mg dose at Week 0, Week 4, and every 12 weeks 
thereafter) as used in the Phase 3 pivotal trials for psoriasis.
Clinical Hypothesis
No formal hypothesis test will be performed.  Summary data will be used to evaluate usability.
2.2 Benefits and Risks to Subjects
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 adverse events (AEs) during the 
treatment and observation periods.  In addition, 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 5.1 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.2,3  There have been no cases of active TB, including no reactivation of TB in subjects 
diagnosed with latent TB, across the entire risankizumab development program.  Across the Phase 3 
psoriasis clinical studies, of the 72 subjects with latent TB who were concurrently treated with 
risankizumab and appropriate TB prophylaxis during the study, none developed active TB during a mean 


  
STUDY M16-005  |  Version 3.0

follow-up of 61 weeks on risankizumab.  Of the 33 subjects in Study M15-992 with a positive test for 
latent TB and who did not receive prophylaxis during the study, none developed active TB during the 
mean follow-up of 77 weeks on risankizumab.
Thus, low risk subjects with positive QuantiFERON testing do not need to be treated with anti-TB 
therapy prior to receiving risankizumab, but should be carefully monitored for any sign of TB 
reactivation.  Absence of TB reactivation, despite not receiving anti-TB prophylaxis, will provide 
important information in humans as to whether TB testing is required prior to treatment with 
risankizumab.4
Published literature indicates that inhibition of IL-23 is unlikely to increase the risk for cancer.  
Expression of IL-23 is increased in human tumors.  Preclinical data have moreover demonstrated 
beneficial effect of IL-23 p19 inhibition in animal models, both for pre-existing and tumor-induction 
models.  However, there is not enough clinical information at this time to rule out a risk of cancer with 
risankizumab, but this risk is considered small.
Although rare, a potential for hepatic adverse events 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.
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.  While the likelihood of increased MACE is 
small, all suspected cardiovascular events (serious or nonserious) observed in this study will be 
adjudicated by an independent adjudication committee.  An independent Cardiovascular Adjudication 
Committee (CAC) will adjudicate all observed cardio- and cerebro-vascular events and will remain 
blinded to treatment allocation (Section 6.2).
Injection-site reactions to biologic therapies may be characterized by redness, swelling, or induration at 
the injection site.  Manifestations of anaphylaxis may include pruritus, hypotension, swollen lips and 
tongue, abdominal pain, and respiratory distress.  Both local and systemic hypersensitivity reactions and 
anaphylaxis are readily detectable, transient in nature, and manageable with standard medical 
treatment.  Subjects will be closely monitored on site during study drug administration at Weeks 0 and 
28.  The duration of the post-drug-administration safety surveillance is 2 hours post-first dose and 
1 hour postdose at Week 28.  Subjects will be given instructions regarding management of signs and 
symptoms of anaphylaxis to be followed during home dosing at Weeks 4 and 16.  An independent 
Anaphylaxis Adjudication Committee (AAC) will adjudicate suspected anaphylactic reactions.  The AAC 
will remain blinded to treatment allocation (Section 6.3).
In conclusion, the benefit-risk profile of risankizumab is considered appropriate for this stage of clinical 
development.  Based on data from the integrated safety analyses, risankizumab is safe and well 
tolerated and demonstrates a favorable benefit-risk profile.  For further details, please see findings from 
completed studies, including safety data in the risankizumab Investigator Brochure.1

4 INVESTIGATIONAL PLAN
4.1 Overall Study Design and Plan
This is a Phase 3 multicenter, single-arm, open-label study that will evaluate usability of the 
risankizumab-AI combination product.  In addition, efficacy will be evaluated by a study treatment 
assessor.  The study includes a 30-day screening period with study visits at Week 0, 4, 16, 28, and 40 
with a subsequent follow-up telephone call at approximately 20 weeks after the last dose of study drug 
(Week 48).  Study drug dosing will consist of four self-administered doses given subcutaneously on 
Weeks 0, 4, 16, and 28.  Dosing on Week 4 and Week 16 will be self-administered at home.
The schematic of the study is shown in Figure 1.

Study Schematic
AI = autoinjector
If an exclusionary laboratory result is obtained at the initial Screening Visit, one re-test of that particular 
test is allowed without repeating all other laboratory tests within the 30 day screening window.
Subjects who initially do not meet all eligibility criteria for the study may be permitted to repeat the 
Screening Visit one time following re-consent.  The subject must meet all eligibility criteria on the repeat 
Screening Visit in order to qualify for the study.  The repeat screening procedure is:


  
STUDY M16-005  |  Version 3.0
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
•
A repeat of all screening procedures is needed at this repeat Screening Visit with these 
exceptions:
•
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 at the repeat Screening Visit.
•
There is no minimum period of time a subject must wait prior to the repeat Screening Visit.
Subjects will be instructed at Week 0 (pre-injection) by the site staff on how to self-inject via the AI.  
Self-injections will be administered into one of the following body regions, changing the injection site if 
possible at each time point:  right thigh, left thigh, right abdominal area, left abdominal area.
At Week 0 (after training) and Week 28, subjects will be instructed by site staff to refer to the IFU (refer 
to Appendix E of the Operations Manual) and proceed with self-injection.  At the Week 4 and Week 16 
Visits, subjects will be sent home with one AI to be self-administered within 24 hours of the Week 4 and 
Week 16 Visit respectively, with instructions from the site staff to use the IFU.  The Week 0 and Week 28 
usability assessments will take place in the context of an observed assessment under the supervision of 
one site staff member.  Each assessment is to be conducted on a 1:1 basis.  The observer (site staff 
member) will measure and evaluate the subject's usability of the AI using the self-injection assessment
checklist as they observe the injections at Week 0 and Week 28.
Site staff will assess potential use-related hazards with a predefined possible hazards checklist (refer to 
Appendix G of the Operations Manual) for self-injections at Week 0 and Week 28.  During the self-
injection, if a subject is not acting in a safe or reasonable manner the observing site staff member is 
required to intervene.  Use errors, which could pose a risk to the health or well-being of a subject, 
require the observing staff member to ask the subject to pause, to point out the use error, and to decide 
whether to terminate the self-injection.  If the observing site staff member's judgment the self-injection 
can continue, they should correct the subject's usage of the product and notify the subject to 
recommence at the same point.  These errors will be documented from the list of potential use-related 
hazards.  Any risk of a health and safety incident could result in termination of the self-injection at the 
discretion of the observing site staff member.
Subject-derived usability assessment measures acceptability of the AI using the SIAQ.  Subjects will fill 
out the SIAQ PRE module (refer to Appendix B of the Operations Manual) immediately before the first 
self-injection at Week 0 and the POST module 20 to 40 minutes following self-injections at Week 0, 
Week 4, Week 16, and Week 28.  These modules are to be completed by subjects while alone in a quiet 
environment.  The subject's self-rated assessment of each item of the SIAQ, will be transformed during 
analysis to scores ranging from 0 (worst experience) to 10 (best experience) as described in Appendix B 
of the Operations Manual.
At Week 0, after the subject self-injects, the site will collect the used AI and examine them for technical 
performance.  The site will document the result in the appropriate eCRF.
See Section 5 for information regarding eligibility criteria.

An interim analysis will occur after all ongoing subjects complete the Week 28 Visit.  Efficacy assessors 
will remain blinded for the duration of the study.
4.2 Discussion of Study Design
Choice of Control Group
This is an open-label study.  There is no control group.
Appropriateness of Measurements
Standard statistical, efficacy, and safety procedures will be utilized in this study.  All efficacy 
measurements in this study are standard for assessing disease activity in subjects with moderate to 
severe plaque psoriasis.  All clinical and laboratory procedures in this study are standard and generally 
accepted.
The SIAQ evaluates patients' experiences with self-injection and enables assessment of their success in 
giving self-injections and the likelihood of them adhering to a self-injection regimen.5  It has been 
validated in patients with rheumatoid arthritis and measured in patients with psoriasis and psoriatic 
arthritis.6-8
Suitability of Subject Population
Subjects who have moderate to severe plaque psoriasis, defined as a PASI score ≥ 12, body surface area 
(BSA) involvement ≥ 10%, and sPGA ≥ 3 who are candidates for systemic therapy are eligible for this 
study.  Criteria such as laboratory values (minimums and maximums) and subject history (absence of 
chronic infections such as human immunodeficiency virus [HIV], hepatitis B or C [HBV, HCV]), and other 
exclusions are specified to ensure subject safety and to allow adequate evaluation of the study drug.  
The study population selected reflects a standard population for moderate to severe psoriasis trials with 
new treatment intervention.
Selection of Doses in the Study
The risankizumab dosing regimen selected for the current study is the same as used in the risankizumab 
pivotal Phase 3 studies in subjects with moderate to severe chronic plaque psoriasis.  Risankizumab has 
been found to be safe and well tolerated with no dose limiting safety findings following single- or 
multiple-dose administration at doses up to 
 mg SC or 1800 mg intravenously in Phase 1 to 3 clinical 
studies.1
Blinded Efficacy Assessor
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, and sPGA at all 
appropriate study visits (Table 1).  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 


  
STUDY M16-005  |  Version 3.0

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 electronic case report form (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.

symptothermal, post-ovulation methods] and withdrawal are not acceptable.
If required per local guidelines, male or female condom with or without spermicide OR cap, diaphragm 
or sponge with spermicide should be used in addition to one of the birth control methods listed above 
(excluding true abstinence).
Contraception recommendations related to use of concomitant therapies prescribed per standard of 
care should be based on the local label.

Vaccines that are inactivated, toxoid, or biosynthetic may be administered at any time without 
restrictions.  Examples of common vaccines that meet these criteria include but are not limited to:  
injectable influenza vaccine, pneumococcal, pertussis (Tdap), and Shingrix®.
5.4 Prior and Concomitant Therapy
Stable doses of concomitant therapies for chronic conditions, for which neither the condition nor the 
treatment are judged to exclude the patient from participation are permissible.  All concomitant 
medications should be carefully evaluated by the investigator, and the AbbVie clinical monitor should be 
contacted when there are questions regarding concomitant medications.
Subjects must be able to safely discontinue any prohibited medications 5 half-lives or 4 weeks prior to 
initial study drug administration.  Subjects must be consented for the study prior to discontinuing any 
prohibited medications for the purpose of meeting study eligibility.
5.5 Withdrawal of Subjects and Discontinuation of Study
A subject will be discontinued from study drug if any of the following occurs:
•
Clinically significant abnormal laboratory result(s) or AE(s) that preclude continuation of the 
study medication, as determined by the Investigator and the Therapeutic Area Medical Director 
(TA MD) (as applicable).
•
The Investigator believes withdrawal from the study is in the best interest of the subject.


  
STUDY M16-005  |  Version 3.0
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
•
The subject requests withdrawal from the study.
•
Eligibility criteria violation(s) are noted after the subject started study drug, if continuation of 
the study drug would place the subject at risk as determined by the AbbVie TA MD, after 
consultation with the Investigator
•
Introduction of prohibited medications and continuation of the study drug would place the 
subject at risk as determined by the AbbVie TA MD
•
Subject develops active TB at any time during the study.
•
Subject becomes pregnant while participating in the study.
•
Subject is diagnosed with a malignancy.  Exception:  localized non-melanoma skin cancer 
(NMSC) or carcinoma in-situ of the cervix, where discontinuation is at the discretion of the 
Investigator.
•
Subject is significantly noncompliant with study procedures, which would put the subject at risk 
for continued participation in the trial.
For subjects to be considered lost to follow-up, reasonable attempts must be made to obtain 
information on the subject's final status.  At a minimum, 2 telephone calls must be made and 1 certified 
letter must be sent and documented in the subject's source documentation.
AbbVie may terminate this study prematurely, either in its entirety or at any site.  The investigator may 
also stop the study at his/her site if he/she has safety concerns.  If AbbVie terminates the study for 
safety reasons, AbbVie will promptly notify the investigator.
5.6 Follow-Up for Subject Withdrawal from Study
To minimize missing data for efficacy and safety assessments, subjects who prematurely discontinue 
study drug treatment should continue to be followed for all regularly scheduled visits, unless subjects 
have decided to discontinue the study participation entirely (withdrawal of informed consent).  Subjects 
should be advised on the continued scientific importance of their data even if they discontinue 
treatment with study drug early.
If a subject prematurely discontinues study participation (withdrawal of informed consent), the 
procedures outlined for the Premature Discontinuation visit (PD visit) should be completed as soon as 
possible, preferably within 2 weeks.  In addition, a follow-up phone call 20 weeks (140 days) after the 
last dose of study drug may be completed to ensure all treatment-emergent AEs/serious AEs (SAEs) have 
been resolved.
5.7 Study Drug
Information about the study drug used in this study is presented in Table 2.


  
STUDY M16-005  |  Version 3.0
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
Table 2.
Description of Study Drug
Study Drug
Dosage Form
Strength
Route of 
Administration
Risankizumab (ABBV-066) 
Solution for injection in 
AI 
150 mg/1.0 mL 
(150 mg/mL)
SC injection
AI = auto-injector; SC = subcutaneous
Open-label risankizumab will be packaged in quantities sufficient to accommodate study design.  Each 
kit will be labeled per local requirements and this label must remain affixed to the kit.  Risankizumab kits 
will be kept protected from light in their original packaging, in a refrigerator between 2°C to 8°C (36°F to 
46°F), and within a secure limited access storage area, and in accordance with the recommended 
storage conditions on the label.  Risankizumab must not be frozen at any time.  At the Week 4 and 
Week 16 visits, subjects will be provided with a cooler bag and ice pack to maintain adequate storage 
temperature of the study drug kit.  They will also be provided with a sharps containers to allow the 
subjects to safely transport the used AI back to the study site after self-administration of the dose at 
home.
Upon receipt, study drug should be stored as specified on the label and kept in a secure location.  A 
temperature log must be maintained for documentation.  Each kit will contain a unique kit number.  This 
kit number is assigned to a subject via interactive response technology (IRT) and encodes the 
appropriate study drug to be dispensed at the subject's corresponding study visit.
AbbVie will not supply drug other than risankizumab, and study drug will only be used for the conduct of 
this study.  AbbVie provided study drug should not be substituted or alternately sourced unless 
otherwise directed by AbbVie.
5.8 Randomization/Drug Assignment
All subjects will receive open-label risankizumab; however, the efficacy assessor will remain blinded to 
each subject's treatment, clinical laboratory results, and all subject safety data during the course of the 
study.
In the event of a medical emergency in which the Investigator believes that knowledge of study drug 
treatment is required for the efficacy assessor, reasonable efforts must be made to contact the AbbVie 
Emergency Contact.
The date and reason that the efficacy assessor's blind was broken must be recorded in the source 
documentation and eCRF, as applicable.
5.9 Protocol Deviations
The investigator is responsible for complying with all protocol requirements, written instructions, and 
applicable laws regarding protocol deviations.  Protocol deviations are prohibited except when 
necessary to eliminate an immediate hazard to study subjects.  If a protocol deviation occurs (or is

identified), the investigator is responsible for notifying IEC/IRB, regulatory authorities (as applicable), 
and AbbVie.
6 SAFETY CONSIDERATIONS
6.1 Complaints and Adverse Events
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.  Complaints associated with any component of this investigational 
product must be reported to AbbVie.
Product Complaint
A product complaint is any complaint 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 (e.g., printing illegible), missing components/product, device not working properly, 
or packaging issues.
Product Complaints concerning the investigational product and/or device must be reported to AbbVie 
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 AbbVie (or an authorized representative) and documented in source as 
required by AbbVie.  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.  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.
Medical Complaints/Adverse Events and Serious Adverse Events
An adverse event 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.
The investigators will monitor each subject for clinical and laboratory evidence of adverse events on a 
routine basis throughout the study.  All adverse events will be followed to a satisfactory conclusion.


  
STUDY M16-005  |  Version 3.0
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
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.
If an adverse event, whether associated with study drug or not, meets any of the following criteria, it is 
to be reported to AbbVie clinical pharmacovigilance or contract research organization (CRO) (as 
appropriate) as a serious adverse event within 24 hours of the site being made aware of the serious 
adverse event (refer to Section 4.3 of the Operations Manual for reporting details and contact 
information):
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).


  
STUDY M16-005  |  Version 3.0
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
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.
All adverse events reported from the time of study drug administration until 20 weeks (140 days) after 
discontinuation of study drug administration will be collected, whether solicited or spontaneously 
reported by the subject.  In addition, serious adverse events and protocol-related nonserious adverse 
events will be collected from the time the subject signs the study-specific informed consent.
AbbVie will be responsible for Suspected Unexpected Serious Adverse Reactions (SUSAR) reporting for 
the Investigational Medicinal Product (IMP) in accordance with global and local requirements.
Adverse events will be monitored throughout the study to identify any of special interest that may 
indicate a trend or risk to subjects.
If AEs in any of the following areas of safety interest (ASI) are reported during the study, then the 
corresponding supplemental report must be completed (Table 3).




  
STUDY M16-005  |  Version 3.0
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
•
Grade 4 (Severe); Life-threatening consequences; urgent intervention indicated.  
•
Grade 5 (Severe); Death related to AE.
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.
Pregnancy
While not an adverse event, pregnancy in a study subject must be reported to AbbVie within 1 working 
day after the site becomes aware of the pregnancy.  Subjects who become pregnant during the study 
must be discontinued (Section 5.5).  If a pregnancy occurs in a study subject, information regarding the 
pregnancy and the outcome will be collected.
The pregnancy outcome of an elective or spontaneous abortion, stillbirth or congenital anomaly is 
considered a SAE and must be reported to AbbVie within 24 hours after the site becomes aware of the 
event.
6.2 Cardiovascular Adjudication Committee
An independent adjudication committee will be adjudicating all observed cardio- and cerebro-vascular 
events and will remain blinded to treatment allocation.  The events that are adjudicated and the 
adjudication process will be detailed in the CAC Adjudication Committee Charter.  Dedicated eCRFs will 
be used as outlined in Table 3.
In addition, the site may be contacted for additional source documentation for relevant events.
6.3 Anaphylaxis Adjudication Committee (AAC)
While no concerns with systemic hypersensitivity have been identified with the use of risankizumab, the 
sponsor has established an independent, blinded, expert committee to adjudicate events of anaphylaxis 
based on pre-specified definitions.  This independent external Anaphylaxis Adjudication Committee 
(AAC) will adjudicate suspected anaphylactic reactions and will remain blinded to treatment allocation.  
The event terms to be adjudicated and the adjudication process are detailed in the AAC Charter.  A 
supplemental Hypersensitivity Reactions eCRF will be used to collect information pertinent to the events 
(Table 3).  In addition, the site may be contacted for additional source documentation.
If a suspected systemic hypersensitivity reaction occurs at the investigative site, subjects should be 
tested for tryptase and histamine levels.  If a systemic hypersensitivity reaction such as anaphylaxis is 


  
STUDY M16-005  |  Version 3.0

observed or reported while the subject is not at the investigative site, every effort should be made to 
obtain tryptase and histamine levels from the treating facility to help better characterize the diagnosis.
6.4 Product Complaint
A product complaint is any complaint 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 (e.g., printing illegible), missing components/product, device not working properly, 
or packaging issues.
Product complaints concerning the investigational product and/or device must be reported to AbbVie 
within 1 business day of the study site's knowledge of the event.  Product complaints occurring during
the study will be followed up to a satisfactory conclusion.
7 STATISTICAL METHODS & DETERMINATION OF SAMPLE SIZE
7.1 Statistical and Analytical Plans
The statistical analysis will be described and fully documented in the Statistical Analysis Plan (SAP).  The 
statistical analyses will be performed using SAS (SAS Institute Inc., Cary, North Carolina, USA).
7.2 Definition for Analysis Populations
The intent-to-treat (ITT) Population, which is defined as all subjects who have at least one dose of study 
drug in Study M16-005, will be used for the efficacy and usability analyses.  The Safety Population, which 
is defined as all subjects who received at least one dose of study drug in Study M16-005, will be used for 
all safety analyses.  In this study, the safety population is the same as the ITT population.
7.3 Statistical Analyses for Efficacy
All summary statistics for the efficacy analysis will be conducted in the ITT Population.  No statistical 
tests will be performed.
Non-Responder Imputation (NRI) will be used for categorical endpoints.  Mixed-effect Model Repeat 
Measurements (MMRM) will be used for continuous endpoints.
Details on the efficacy analyses are provided in the Statistical Analysis Plan (SAP).
Sample Size Estimation
This study is designed to enroll approximately 100 subjects who will self-administer the risankizumab-AI 
combination product at Weeks 0, 4, 16, and 28.


  
STUDY M16-005  |  Version 3.0
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
Assuming the point estimate is 90% for the proportion of subjects with an observer rating of successful 
subject self-administration at Week 28, the current sample size of 100 subjects will provide a 
95% confidence interval of ± 5.9% around a point estimate.
In addition, assuming comparable response rates as the Phase 3 pivotal studies, with the current sample 
size of 100, the PASI 90 rate at Week 16 can be estimated with a 95% confidence interval of ± 8.6% 
when the point estimate is 74%; and the sPGA of clear or almost clear rate at Week 16 can be estimated 
with a 95% confidence interval of ± 7.0% when the point estimate is 85%.
7.4 Statistical Analyses for Safety
All safety analyses will be performed on the Safety Populations.  A treatment-emergent adverse event 
(TEAE) is defined as an event with onset or worsening after the first dose of study drug and within 
20 weeks (140 days) after the last dose of study drug.  The number and percentage of subjects 
experiencing TEAEs will be tabulated using the Medical Dictionary for Regulatory Activities (MedDRA) 
system organ class (SOC) and preferred term (PT), by severity, and by relationship to the study drug as 
assessed by the investigator.  Summaries (including percentages and events per 100 PYs) of SAEs, 
deaths, and AEs leading to discontinuation will be provided as well.  Pre-treatment AEs will be 
summarized separately.  For selected laboratory parameters, a listing of all subjects with any laboratory 
value that is above Grade 3 of Common Toxicity Criteria will be provided.  Mean change in laboratory 
and vital signs variables will be summarized.  Additional details for the safety analysis are provided in the 
SAP.
7.5 Study Interim Analysis
An interim analysis will occur after all ongoing subjects complete the Week 28 Visit.
8 ETHICS
8.1 Independent Ethics Committee/Institutional Review Board 
(IEC/IRB)
The protocol, informed consent form(s), recruitment materials, and all subject materials will be 
submitted to the IEC/IRB for review and approval.  Approval of both the protocol and the informed 
consent form(s) must be obtained before any subject is enrolled.  Any amendment to the protocol will 
require review and approval by the IEC/IRB before the changes are implemented to the study.  In 
addition, all changes to the consent form(s) will be IEC/IRB approved.

Introduction
This Statistical Analysis Plan (SAP) describes the statistical analyses for risankizumab 
Study M16-005 A Multicenter, Single-Arm, Open-Label Study to Assess the Usability of 
the Risankizumab Autoinjector Combination Product in Adult Patients with Moderate to 
Severe Plaque Psoriasis.  Study M16-005 evaluates the usability of the combination 
product of risankizumab in an AI and to evaluate the efficacy, safety, and tolerability of 
risankizumab 150 mg/mL administered by AI for the treatment of adult patients with 
moderate to severe plaque psoriasis.
This SAP provides summaries of the planned statistical analyses for efficacy and safety 
endpoints, interim analysis, and overall type-I error control strategies.
There will be no analyses of pharmacokinetic endpoints in this study.
The SAP will not be updated in case of administrative changes or amendments to the 
protocol unless the changes impact the analysis.

(SIAQ; Operations Manual Appendix B) at each visit collected.
2.2
Study Design Overview
This is a Phase 3 multicenter, single-arm, open-label study that will evaluate usability of 
the risankizumab-AI combination product.  In addition, efficacy will be evaluated by an 
efficacy assessor.  The study includes a 30-day screening period with study visits at 
Week 0, 4, 16, 28, and 40 with a subsequent follow-up telephone call at approximately 
20 weeks after the last dose of study drug (Week 48).  Study drug dosing will consist of 
four self-administered doses given subcutaneously on Weeks 0, 4, 16, and 28.  Dosing on 
Week 4 and Week 16 will be self-administered at home.  Efficacy assessments will be 
performed at each study visit (Weeks 0, 4, 16, 28, and 40).
The schematic of the study is shown in Figure 1.

Treatment Assignment and Blinding
All subjects will receive open-label risankizumab. 
2.4
Sample Size Determination
This study is designed to enroll approximately 100 subjects who will self-administer the 
risankizumab-AI combination product at Weeks 0, 4, 16, and 28.
Assuming the point estimate is 90% for the proportion of subjects with an observer rating 
of successful subject self-administration at Week 28, the current sample size of 
100 subjects will provide a 95% confidence interval of ± 5.9% around a point estimate.

In addition, assuming comparable response rates as the Phase 3 pivotal studies, with the 
current sample size of 100, the PASI 90 rate at Week 16 can be estimated with a 95% 
confidence interval of ± 8.6% when the point estimate is 74%; and the sPGA of clear or 
almost clear rate at Week 16 can be estimated with a 95% confidence interval of ± 7.0%
when the point estimate is 85%.

Handling of Missing Data
Missing data will be imputed using the following methods for the efficacy analyses:


Risankizumab
M16-005 – Statistical Analysis Plan
Version 5.0 – 22 April 2020
13
●
Non-Responder Imputation (NRI):  The NRI analysis will categorize any 
subject who does not have evaluation during a specific visit window as a non-
responder for that visit.  The exceptions are: (1) if the subject is a responder 
both before and after a specific visit window in the particular period, then the 
subject will be categorized as a responder for the visit; (2) when the subject 
missed a visit due to COVID-19 pandemic, the missing assessment from that 
visit will be imputed using Multiple Imputation (MI) to determine the 
corresponding response status.  In present study, only Week 28 or later visits 
may be affected by the COVID-19 pandemic.  The NRI will be the primary 
missing data imputation approach in the analyses of categorical variables.
●
Modified-NRI:  Patients who discontinue study drug due to lack of efficacy or 
due to AE of worsening of psoriasis and do not have Week 16 measurements 
will be counted as non-responders.  Other patients will be summarized using 
as-observed data.  The modified-NRI analysis will be the sensitivity approach 
to handle missing data in the analysis of key efficacy endpoints specified in 
Section 3.1.
●
As-observed:  The as-observed analysis will include all available assessments 
on a scheduled visit. No missing assessments will be imputed. The as-
observed analysis will be the sensitivity approach to handle missing data in the 
analysis of the key efficacy endpoints specified in Section 3.1.
●
Mixed-effect Model Repeat Measurement (MMRM):  The repeated measures 
analysis will be conducted using a mixed model including baseline value and 
observed measurements at all post-baseline visits, using all available data even 
if a subject has missing data at some post-baseline visits.  The mixed model 
includes visit as the covariate.  An unstructured variance covariance matrix 
will be used.  Parameter estimation is based on the assumption of data being 
missing at random and using the method of restrictive maximum likelihood 
(REML).  MMRM will be the primary approach in the analysis of continuous 
variables.
The key usability endpoints will be summarized by as-observed cases.

Changes in laboratory parameters will be tabulated using shift tables categorized as low, 
normal, or high based on the normal ranges of the laboratory used for each sample.  A 
shift table from baseline to minimum and maximum value (based on normal range), will 
be created.  A similar shift table will be provided to summarize shifts from baseline to the 
final post-baseline value.
Laboratory abnormalities meeting CTC criteria grade 3 and 4 will be summarized.
Laboratory abnormalities will be evaluated based on Potentially Clinically Important 
(PCI) criteria (Appendix C).  For each laboratory PCI criterion, the number and 
percentage of subjects who have a laboratory value meeting the criteria will be 
summarized.  Listings will be provided to summarize subject-level laboratory data for 
subjects meeting PCI criteria.
In addition, ALT/SGPT, AST/SGOT, alkaline phosphatase, and total bilirubin will be 
categorized as follows:
●
< 1.5 × ULN
●
≥ 1.5 × ULN – < 3.0 × ULN
●
≥ 3.0 × ULN – < 5.0 × ULN
●
≥ 5.0 × ULN – < 10.0 × ULN
●
≥ 10.0 × ULN – < 20.0 × ULN
●
≥ 20.0 × ULN
A listing of potentially clinically important liver function laboratory values will include 
all subjects who met any of the following four criteria:
●
ALT ≥ 3 × ULN, or
●
AST ≥ 3 × ULN, or
●
Alkaline Phosphatase ≥ 1.5 × ULN, or 
●
Total bilirubin ≥ 2 × ULN.

A listing of possible Hy's Law cases, defined as those who meet all of the following 
conditions will be provided.  
●
ALT of > 3 × ULN or AST of > 3 × ULN, 
●
Associated with an increase in total bilirubin ≥ 2 × ULN,
●
Alkaline Phosphatase < 2 × ULN

Analysis of Vital Signs
Vital sign measurements of systolic and diastolic blood pressure will be summarized.
Mean change from baseline to each applicable post-baseline visit will be summarized for 
each vital sign variable, with the number of observations, baseline mean, and visit mean.  
The change from baseline mean, standard error, and 95% confidence interval will be 
presented for the mean change from baseline.
Vital sign variables will be evaluated based on potentially clinically important (PCI) 
criteria (Appendix C).  For each vital sign PCI criterion, the number and percentage of 
subjects who have a vital sign value meeting the criteria will be summarized.  Listings 
will be provided to summarize subject-level vital sign data for subjects meeting PCI 
criteria.

Interim Analyses
11.1
Data Monitoring Committee
An external data monitoring committee (DMC) composed of persons independent of 
AbbVie and with relevant expertise in their field will review safety data from the ongoing 
study.  The primary responsibility of the DMC will be to protect the safety of the subjects 
participating in this study.
A separate DMC charter describes the roles and responsibilities of the DMC members, 
frequency of data reviews, relevant data to be assessed, and general operations.
Since there are no efficacy analyses for early stopping, no alpha adjustment is needed.
11.2
Interim Analysis
An interim analysis will occur after all ongoing subjects complete the Week 28 Visit.  All 
efficacy variables up to Week 28, as well as all observed safety and usability variables, 
will be summarized during this analysis.
12.0
Overall Type-I Error Control
No statistical tests will be performed in this single-arm, open-label study.
Since there are no efficacy analyses for early stopping planned for the DMC review, no 
alpha spending is needed due to the DMC review.
