Brief summary:
Atopic dermatitis (AD) is a skin condition that may cause a rash and itching due to inflammation of the skin. Therapies spread over the skin may not be enough to control the AD in trial participants who require systemic anti-inflammatory treatment. This study evaluates the dosing flexibility of upadacitinib in adult participants with moderate to severe AD. Adverse events and change in the disease activity will be assessed.

Upadacitinib is an approved drug for the treatment of moderate to severe/active immune-mediated inflammatory diseases such as rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, ulcerative colitis (UC), Crohn's Disease (CD), and AD. The study is comprised of a 35-day Screening Period, a 12-week double-blind period and a 12-week single-blind period. During the double-blind period, participants are placed in 1 of 2 groups, called treatment arms and will be randomized in a 1:1 ratio to receive upadacitinib. At 12 weeks during the single blind period, participants will be blinded to the upadacitinib dose based on their EASI response and reassigned to in 1 of 4 arms. After the last study visit, there is a 30-day follow-up visit. Approximately 454 adult participants ages 18 to 64 with moderate to severe AD who are candidates for systemic therapy will be enrolled at up to 160 sites worldwide.

The study is comprised of a 12-week double-blind period, followed by a 12-week single-blind period. Participants will receive upadacitinib oral tablets once daily for up to 24 weeks.

There may be higher treatment burden for participants in this trial compared to their standard of care (due to study procedures). Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

Detailed description:

Arms: arm 1: Participants received 15 mg upadacitinib orally once daily (QD) for 12 weeks during the Double-Blind Treatment Period. arm 2: Participants received 30 mg upadacitinib orally once daily (QD) for 12 weeks during the Double-Blind Treatment Period. arm 3: At Week 12 in the Double-Blind Treatment Period, participants receiving 15 mg upadacitinib orally once daily (QD) achieving a ≥ 90% reduction in the Eczema Area and Severity Index (EASI) (≥ EASI 90) were allocated to receive 15 mg upadacitinib orally once daily (QD) for 12 weeks during the Single-Blind Treatment Period. arm 4: At Week 12 in the Double-Blind Treatment Period, participants receiving 15 mg upadacitinib orally once daily (QD) achieving a \< 90% reduction in the Eczema Area and Severity Index (EASI) (\< EASI 90) were allocated to receive 30 mg upadacitinib orally once daily (QD) for 12 weeks during the Single-Blind Treatment Period. arm 5: At Week 12 in the Double-Blind Treatment Period, participants receiving 30 mg upadacitinib orally once daily (QD) achieving a ≥ 90% reduction in the Eczema Area and Severity Index (EASI) (≥ EASI 90) were allocated to receive 15 mg upadacitinib orally once daily (QD) for 12 weeks during the Single-Blind Treatment Period. arm 6: At Week 12 in the Double-Blind Treatment Period, participants receiving 30 mg upadacitinib orally once daily (QD) achieving a \< 90% reduction in the Eczema Area and Severity Index (EASI) (\< EASI 90) were allocated to receive 30 mg upadacitinib orally once daily (QD) for 12 weeks during the Single-Blind Treatment Period.

2 INTRODUCTION
2.1 Background and Rationale
Why Is This Study Being Conducted?
The Janus kinase (JAK) or JAKs are a family of intracellular tyrosine kinases that function as dimers in the 
signaling process of many cytokine receptors.1  The JAKs play a critical role in both innate and adaptive 
immunity, making them attractive targets for the treatment of inflammatory diseases.2-6  Targeting the 
JAK signaling pathway for autoimmune diseases is supported by the involvement of various 
proinflammatory cytokines that signal via JAK pathways in the pathogenesis of these immune-related 
disorders.  The activation of JAK signaling initiates expression of survival factors, cytokines, chemokines, 
and other molecules that facilitate leukocyte cellular trafficking and cell proliferation, which contribute 
to inflammatory and autoimmune disorders.
Upadacitinib is an oral, once-daily, selective, and reversible small-molecule JAK inhibitor, engineered to 
have greater inhibitory potency for JAK1 versus JAK2, JAK3, and tyrosine kinase 2 (TYK2).  Janus kinase 1 
inhibition blocks the signaling of many important pro-inflammatory cytokines, including interleukin
(IL)-2, IL-6, IL-7, and IL-15, IFN-γ, which are known contributors to inflammatory disorders.  It also blocks 
the signaling of IL-4, IL-13, IL-31, IL-22, IFN-γ, TSLP cytokines that play an important role in the 
pathogenesis of atopic dermatitis (AD).
Upadacitinib has been approved for the treatment of moderate to severe/active immune-mediated 
inflammatory diseases such as rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, non-
radiographic axial spondyloarthritis, ulcerative colitis (UC), Crohn's disease (CD), and AD. 
In AD, the efficacy and safety of upadacitinib 15 mg and 30 mg once daily (QD) was assessed in three 
Phase 3 randomized, double-blind, multicentre studies (MEASURE UP 1, MEASURE UP 2 and AD UP),7,8
and the two doses (upadacitinib 15 mg and 30 mg QD) studied in the pivotal trials for AD were approved 
for the treatment of moderate to severe AD in several jurisdictions, including but not limited to the 
European Union, Japan, Canada, and the United States.9  However, the Phase 3 studies for AD were 
designed with a stable regimen of upadacitinib 15 mg or 30 mg QD for 5 years and no dose escalation or 
dose reduction were assessed. 
Regarding treatment targets in AD, an extensive group of experienced dermatologists have been 
working to develop optimized and practical criteria for identifying patients who should receive systemic 
therapy, including definitions of treatment goals, treatment failure, and disease severity following a 
modified eDelphi methodology and expert recommendation.  As a result of this work, a new minimal 
disease activity (MDA) concept and criteria and consensus-based recommendations for optimizing the 
management of AD has been recently published and communicated to the scientific community.10  
Following this new concept, different treatment targets based on the achievement of different 
outcomes measures are categorized as "moderate" and "optimal" targets and the achievement of 
"optimal" targets is defined as MDA.  Physicians and patients/caregivers should aim for optimal 
treatment targets to optimize disease control and patient outcomes when possible.  In terms of Eczema 
Area and Severity Index (EASI) score, EASI 90 (or absolute EASI ≤ 3) is the optimal target to achieve.

CONFIDENTIAL INFORMATION

This study aims to provide descriptive data on the efficacy and safety of dose escalation to upadacitinib 
30 mg QD and dose reduction to upadacitinib 15 mg QD based on a clinical response target (EASI 90)
after 12 weeks of treatment.  This data will inform the clinical management for subjects with moderate 
to severe AD treated with both approved doses of upadacitinib.
2.2 Benefits and Risks to Subjects
In the EU SmPC, upadacitinib has been approved for the treatment of moderate to severe AD in adults 
and adolescents 12 years and older who are candidates for systemic therapy.9
In adults, the recommended dose of upadacitinib is 15 mg or 30 mg QD based on individual patient 
presentation.  A dose of 15 mg is recommended for patients at higher risk of venous thromboembolism, 
major adverse cardiovascular events (MACE), and malignancy.  A dose of 30 mg may be appropriate for 
patients with high disease burden who are not at higher risk of venous thromboembolism, MACE, and 
malignancy or patients with an inadequate response to 15 mg.  The lowest effective dose to maintain 
response should be used.9
For patients ≥ 65 years of age the recommended dose is upadacitinib 15 mg QD.9  The above indication 
and posology correspond to the European Union and may vary within different jurisdictions.
The efficacy and safety of upadacitinib 15 mg and 30 mg QD was assessed in 3 Phase 3 randomized, 
double-blind, multicentre studies (MEASURE UP 1, MEASURE UP 2 and AD UP)7,8 in a total of 
2584 subjects (12 years of age and older).  A significantly greater proportion of subjects treated with 
upadacitinib 15 mg or 30 mg QD achieved validated Investigator´s Global Assessment for AD (vIGA-AD) 0 
or 1, EASI 75, EASI 90, EASI 100, Dermatology Life Quality Index (DLQI) 0 or 1, or a ≥4-point 
improvement on the Worst Pruritus Numerical Rating Scale (NRS) compared to placebo at Week 16.  
Rapid improvements in skin clearance and itch were also achieved.  Results at Week 16 were maintained 
through Week 52 in subjects treated with upadacitinib 15 mg or 30 mg QD.
Adverse events (AEs) such as infections including herpes zoster, major adverse cardiovascular events 
(MACE defined as cardiovascular death, non-fatal myocardial infarctions and non-fatal strokes), 
thrombosis, malignancies, hypersensitivity (serious anaphylactic reaction and angioedema), 
gastrointestinal perforation, bone fractures, and some laboratory abnormalities have been observed in 
patients receiving JAK inhibitors including upadacitinib.
An increased risk of infection including opportunistic infections (e.g., mucosal candida infections) and 
herpes zoster, non-melanoma skin cancer (NMSC), and abnormal laboratory changes have been 
observed (e.g., elevations of serum transaminases, lipids, creatine phosphokinase [CPK], and reductions 
in hemoglobin and neutrophils with upadacitinib therapy. 
In ORAL Surveillance, a post-approval safety study in RA patients 50 years of age and older with at least 
1 cardiovascular risk factor, higher rates of malignancies (excluding NMSC), MACE (cardiovascular death, 
myocardial infarction, and stroke), thrombosis (overall thrombosis, deep vein thrombosis [DVT], and 
pulmonary embolism), and all-cause mortality were seen with a different JAK inhibitor, tofacitinib, 
versus TNF blockers.11  These higher rates were primarily observed in patients 65 years of age and older, 
patients with a history of atherosclerotic cardiovascular disease, and patients with other cardiovascular 
risk factors (such as current or past long-time smokers).  Although upadacitinib clinical trial data to date

have not indicated a higher risk for MACE, venous thromboembolism, malignancies excluding NMSC, or 
deaths in RA patients treated with upadacitinib versus adalimumab, the findings of the ORAL 
Surveillance study may potentially also apply to other JAK inhibitors and an increased risk for these 
events compared to TNF blockers cannot be completely excluded.  Therefore, the investigator should 
consider the benefits and risks of upadacitinib treatment and suitable treatment alternatives in 
determining study participation and the continued use of upadacitinib in patients 65 years of age and 
older, patients with a history of atherosclerotic cardiovascular disease or other cardiovascular risk 
factors, patients who are current or past long-time smokers, and/or patients with other malignancy risk 
factors (e.g., current malignancy or history of malignancy).
The results of genetic toxicology testing indicate that upadacitinib is not genotoxic; however, 
upadacitinib is teratogenic based on animal studies, which necessitates avoidance of pregnancy in 
females of childbearing potential.  Based on the calculated safety margins for human fetal exposure with 
seminal fluid transfer, there is judged to be no risk to the pregnancy of female partners of male subjects 
who are treated with upadacitinib.
A detailed discussion of the pre-clinical and clinical toxicology, metabolism, pharmacology, and safety 
experience with upadacitinib can be found in the current Investigator's Brochure.
Taken together, the safety and efficacy data from upadacitinib studies to date show a favorable 
benefit:risk profile for upadacitinib and support the continued investigation of upadacitinib in patients 
with various immune-mediated inflammatory conditions.
The benefit:risk profile of various immunomodulatory therapies on COVID-19 is being evaluated. At this
time, the effects of upadacitinib on the course of COVID-19 are not well defined.  For further details, 
please see findings from completed studies, including safety data in the current upadacitinib 
Investigator's Brochure.

metabolites, either free or in association with particular cell types.  In addition, pharmacogenetic DNA 
samples may be collected for exploratory analysis of genetic factors contributing to disease pathology 
and subject's response to study treatment.  The biomarker research results may not be included with 
the clinical study report.  Further details regarding the biomarker research rationale and collection time 
points are located in the Operations Manual, Appendix F, Section 3.8.
No biomarker samples will be collected in China.
4 INVESTIGATIONAL PLAN
4.1 Overall Study Design and Plan
This is a Phase 3b/4, randomized, blinded, treat-to-target, dose-flexibility, multi-center study that will 
evaluate upadacitinib, as monotherapy, in approximately 454 adult subjects (≥ 18 and < 65 years of age) 
with moderate to severe AD who are candidates for systemic therapy.
The study is comprised of a 35-day Screening Period, a 12-week double- blind period and a 12-week 
single-blind period.  During the single-blind period, subjects will be blinded to the upadacitinib dose and 
EASI score evaluations.
The study treatment duration will be 24 weeks.
After the last study visit, a 30-day follow-up visit (or phone call if a visit is not possible) will be completed 
to determine the status of any new or ongoing AEs/SAEs and concomitant medications.
Subjects who meet the eligibility criteria will be randomized in a 1:1 ratio to enter SS1 to receive oral 
doses of upadacitinib 15 mg QD at Baseline or SS2 to receive oral doses of upadacitinib 30 mg QD at 
Baseline.

SS1:

Subjects randomized to enter the SS1 at Baseline will receive oral doses of upadacitinib 
15 mg QD during the 12-week double-blind period.

their EASI response, which is calculated based on the observed EASI values regardless of the 
use of rescue medications:

Subjects achieving < EASI 90 will continue to receive oral doses of upadacitinib 30 mg 
QD.  This constitutes the Study Cohort 3 (SC3).

Subjects achieving ≥ EASI 90 will be allocated to receive oral doses of upadacitinib 15 mg 
QD.  This constitutes the Study Cohort 4 (SC4).
The final and only database lock will occur at the end of the study.

Note:
The study will be stratified by Baseline vIGA-AD categories (3; 4) and prior use of dupilumab (yes; no).
Wearable Tool Substudy
Subjects in select countries and sites where the digital health technology device is deployed and 
available will participate in a Wearable Tool Substudy, using ADAM (ADvanced Acousto-Mechanic) 
sensor made by Sibel Health.  Subjects participating in this substudy will wear a digital tool on the back 
of their dominant hand while sleeping for 7 nights prior to the Baseline visit, then for specified weeks 
during the study.  The tool will collect data reflecting the subject's nocturnal scratch and sleep 
parameters by Bluetooth signal to a provided tablet, which transfers the data by cellular network to a 
secure cloud-based server.  Enrollment will be capped at 90 subjects.
The ADAM Sensor, manufactured by Sibel, collects actigraphy data through raw acoustic signals and 
mechanical movement to quantify nocturnal scratch duration and intensity.  The sensor offers streaming 
ability through the mobile ADAM application and is integrated with the vendor's cloud and web 
application.  Data, which may be in raw/preliminary format, collected by the vendor, will be accessible 
to the clinical investigator.  The digital tool is for Research Use Only and will not be used for diagnosis or 
treatment.  All source data will be retained by AbbVie and the investigators per 21 CFR 312.62(b), 
812.140(a)(3), and ICH-GCP 8.1.

Appropriateness of Measurements
Standard statistical, clinical, and laboratory procedures will be utilized in this study.  All efficacy and 
safety related measurements in this study are standard for assessing disease activity in subjects with 
moderate to severe AD.  All clinical and laboratory procedures in this study are standard and generally 
accepted.
Care should be taken to minimize the pain and discomfort of laboratory procedures.  Use of a butterfly 
needle for venipuncture and/or a needle gauge appropriate for vein size may optimize the comfort for 
some individuals.  Attempts at venipuncture should be limited to the subject's tolerance of the 
procedure; after more than 2 unsuccessful attempts for venipuncture, consider requesting the subject 
to return at a later time for the blood sample collection within the timeframe allowed by the protocol.
Suitability of Subject Population
The target study population for this study represents an adult AD population with moderate to severe 
disease activity appropriate for systemic therapies.  Adult subjects ≥ 18 and < 65 years of age will be 
eligible for the study.
Selection of Doses in the Study
This study will evaluate two doses of upadacitinib (15 mg and 30 mg QD).
The dose selection was informed by the 2 doses (upadacitinib 15 mg and 30 mg QD) studied in the 
pivotal trials for AD and approved for the treatment of moderate to severe AD in several jurisdictions, 
including but not limited to the European Union, Japan, Canada, and United States.  Both doses showed 
a positive benefit-risk profile, and the objective of this study is to generate data that will help inform the 
more appropriate use of both approved doses.
All currently available Pharmacokinetic(s), Pharmacodynamic, Safety and Efficacy Data from upadacitinib 
studies were used to support the selection of these doses.
5 STUDY ACTIVITIES
5.1 Eligibility Criteria
Subjects must meet all of the following criteria in order to be included in the study, in consideration of

Baseline EASI score.
Investigators should attempt to limit the first step of rescue therapy to topical medications and escalate 
to systemic medications only for those subjects who do not respond adequately after at least 7 days of 
topical treatment.  Subjects who receive topical rescue treatment during the study treatment period can 
continue study drug.
If a subject needs rescue treatment with a systemic agent (including but not limited to corticosteroids, 
cyclosporine, methotrexate, mycophenolate mofetil, azathioprine, biologics) or phototherapy, study 
drug should be permanently discontinued prior to the initiation of rescue systemic agent or 
phototherapy and the subject should be discontinued from the study.  Investigators should conduct 
efficacy and safety assessments (e.g., disease severity scores, safety labs) before administering any 
rescue treatment.  An unscheduled visit may be used for this purpose if necessary.

if required locally] before first dose of study drug) and there is no known history of primary varicella 
(chicken pox), preexisting immunity to varicella should be confirmed with antibody testing at or prior to 
Screening and prior to administration of the herpes zoster vaccine.  If screening varicella antibody 
testing is negative, the live herpes zoster vaccine should not be administered.
In Japan, it is recommended that the live herpes zoster vaccine be considered for administration at least 
8 weeks before the first dose of study drug in subjects greater than 50 years of age.
Administration of inactivated (non-live) vaccines is permitted prior to or during the study according to 
local practice guidelines.  Examples of common vaccines that are inactivated, toxoid or biosynthetic 
include, but are not limited to, injectable influenza vaccine, pneumococcal, Shingrix (zoster vaccine, 
recombinant, adjuvanted), pertussis (Tdap) vaccines and SARS-CoV-2 (inactivated, mRNA, RNA). 
Whenever possible, subjects should not have received a COVID-19 vaccination in the 7 days prior to 
randomization or plan to receive a COVID-19 vaccination within the first 7 days after initiation of study 
drug.  Viral vector vaccines that are not of replicating potential (such as Convidecia® and Convidecia Air 
to treat COVID-19) are allowed.
COVID-19 Pandemic-Related Vaccination Guidance
Given the ongoing COVID-19 pandemic, selected non-live vaccines (e.g., mRNA, non-replicating viral 
vector, protein subunit, etc.) to prevent SARS-CoV-2 infection may be administered during screening, 
the treatment period, or follow up, as long as components of the vaccine are not contraindicated.

CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
The decision to receive a locally available vaccine should be based on local guidance and an individual 
discussion between the treating physician and the subject.
The potential impact of upadacitinib on SARS-CoV-2 vaccination is unknown.  Therefore, study drug 
should be administered as follows:

The first dose of upadacitinib, when possible, is preferred to be given at least ± 7 days from the 
SARS-CoV-2 vaccine administration.
Note:  The above guidance applies to all SARS-CoV-2 vaccine doses given as part of the complete 
vaccination course.
These recommendations may be subject to change based on the evolving knowledge around the use of 
SARS-CoV-2 vaccines in patients with AD and as more data are collected in real-world scenarios and 
clinical trials.
Any SARS-CoV-2 vaccine information must be documented on the COVID-19 vaccine eCRF.  Refer to the 
Operations Manual for instructions on reporting any AEs associated with the COVID-19 vaccine.
5.5 Withdrawal of Subjects and Discontinuation of Study
AbbVie may terminate this study prematurely, either in its entirety or at any site.  The study may be 
discontinued or terminated in case of an unacceptable risk, any relevant toxicity, or a negative change in 
the risk/benefit assessment.  This might include the occurrence of AEs with a character, severity or 
frequency that is new in comparison to the existing risk profile.  In addition, data deriving from other 
clinical trials or toxicological studies which negatively influence the risk/benefit assessment might cause 
discontinuation or termination of the study.  The investigator may also stop the study at their site if they 
have safety concerns.  If AbbVie terminates the study for safety reasons, AbbVie will promptly notify the 
investigator.  Advance notice is not required by either party if the study is stopped due to safety 
concerns.
Subjects can request to be discontinued from participating in the study at any time for any reason.  The 
investigator may discontinue any subject's participation at any time for any reason.
Subjects must have study drug discontinued immediately if any of the following occur:

The subject requests withdrawal from study drug or the study.

The investigator believes it is in the best interest of the subject.

Abnormal laboratory results or AEs that either meet the criteria for discontinuation of study 
drug as stated in Section 6.2, or rule out safe continuation of the study drug.  

Serious infections (e.g., sepsis) which cannot be adequately controlled by anti-infective 
treatment or would put the subject at risk with continuation of the study drug.

Confirmed diagnosis of deep vein thrombosis (DVT), pulmonary embolus (PE) or non-cardiac, 
non-neurologic arterial thrombosis.


Subject is non-compliant with TB prophylaxis (if applicable) or develops active TB at any time 
during the study.

Malignancy, except for localized NMSC or carcinoma in-situ of the cervix if this can be 
successfully treated at its localization

Subject develops a gastrointestinal perforation (other than due to appendicitis or mechanical 
injury).

The subject experiences a serious hypersensitivity reaction without an alternative etiology.

The subject becomes pregnant while on study drug.

Eligibility criteria violation was noted after the subject started study drug, when continuation of 
the study drug would place the subject at risk.

Introduction of prohibited medications or dosages when continuation of the study drug would 
place the subject at risk.

The investigator determines the subject is significantly non-compliant with the study.

Initiation of any prohibited systemic therapy for AD. 

Initiation of phototherapy.

Treatment with a live (attenuated) vaccine with replicating potential.
Additional requirements related to abnormal laboratory values and selected AE of special interest 
(AESIs) are in Protocol Section 6.2 (Toxicity Management).
COVID-19 Pandemic-Related Acceptable Protocol Modifications
During the COVID-19 pandemic, it has been necessary to employ mitigation strategies to enable the 
investigator to ensure subject safety and continuity of care.  Acceptable mitigation strategies are 
identified and included in the Operations Manual in Appendix F.
The investigator should contact the sponsor medical contact before discontinuing a subject from the 
study for a reason other than described in the protocol to ensure all acceptable mitigation steps have 
been explored.
Interruption/Discontinuation of Study Drug Due to COVID-19 Infection
During the study drug dosing period, for a subject with confirmed (viral test positive) or suspected 
COVID-19 infection, the timing of next administration of study drug or possibility of premature 
discontinuation would be at the discretion of the investigator.  Follow Section 5.6 for subjects who 
discontinued study drug.
Delays in study drug dosing due to the above COVID-19 testing guidance for subjects must be discussed 
with the AbbVie medical contact, along with the possibility of premature discontinuation from the study 
drug dosing period.  Follow subsequent protocol Section 5.6 for subjects who discontinued study drug.

5.6 Follow-Up After Subject Discontinuation of Study Drug or From
Study
Discontinuation of Study Drug
Following discontinuation of study drug, the subject should be treated in accordance with the 
investigator's best clinical judgment based on the available approved treatment options within their 
country or region.
Subjects who prematurely discontinue study drug treatment will be discontinued from study 
participation entirely.
If a subject prematurely discontinues study drug, the procedures outlined for the Premature 
Discontinuation visit (PD Visit) should be completed as soon as possible, preferably within 2 weeks, and 
preferably prior to initiation of another therapy.  In addition, a 30-Day Follow-up Visit after the last dose 
of study drug is required to ensure all treatment-emergent AEs/SAEs have been resolved.  For subjects 
who prematurely discontinued study participation, this visit may be a telephone call if a site visit is not 
possible.  A follow-up phone call following the last dose of upadacitinib during the study will not occur 
for subjects who begin commercially available upadacitinib.
Premature Discontinuation of Study (Withdrawal of Informed Consent)
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 and preferably prior to initiation of another therapy.  In addition, if 
the subject is willing, a 30-day follow-up phone call after the last dose of study drug may be completed 
to ensure all treatment-emergent AEs/SAEs have been resolved.  The follow-up phone call following the 
last dose of upadacitinib during the study will not occur for subjects who begin commercially available 
upadacitinib.
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.
If a subject withdraws from study follow up or withdraws permission for the collection of their personal 
data, the study staff may still use available public records to obtain information about survival status 
only, as appropriate per local regulations.
If a subject withdraws consent from the clinical study, biomarker research will continue unless the 
subject explicitly requests analysis to be stopped.  When AbbVie is informed that samples are withdrawn 
from research, samples will not be analyzed, no new biomarker analysis data will be collected for the 
withdrawn subject or added to the existing data or database(s), and the samples will be destroyed.  A 
subject may withdraw consent for optional biomarker research at any time and remain in the clinical 
study.  Data generated from clinical study and/or optional biomarker research, before subject 
withdrawal of consent, will remain part of the study results.

QD = once daily
Upadacitinib will be taken orally once daily, beginning on Day 1 (Baseline) and can be taken with or 
without food.  Upadacitinib should be taken whole and should not be split, crushed, dissolved, etc.  If 
subjects should forget to take upadacitinib at their regularly scheduled dosing time, they should take the 
forgotten dose as soon as they remember as long as it is at least 10 hours before their next scheduled 
dose.  Otherwise, they should take the next dose at the next scheduled dosing time.
The subject will be instructed to return all drug containers (even if empty) to the study site personnel at 
each study visit.  The study site personnel will document compliance.
AbbVie will provide upadacitinib.  AbbVie-provided study drug should not be substituted or alternately 
sourced unless otherwise directed by AbbVie.
AbbVie will not supply drug other than upadacitinib.  Subjects will continue their AD disease-related 
concomitant medications therapy as allowed per protocol.  AbbVie will not supply any AD disease-
related concomitant medication therapy taken during the study.
Study drug 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.  Upon receipt, study drug 
should be stored as specified on the label and kept in a secure location.  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.  All blank spaces 
on the label will be completed by the site staff prior to dispensing to subjects.  Study drug will only be 
used for the conduct of the study.
During the COVID-19 pandemic, study drug shipment can be made from the study site to the subject if 
allowed by local regulations.  Refer to the Operations Manual for details on direct-to patient shipment 
of study drug (Appendix F).

CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
Upon completion of or discontinuation from study treatment, all original study drug units (containing 
unused study drugs) will be returned to the sponsor (or designee) or destroyed on site.  All return or 
destruction procedures will be according to instructions from the Sponsor according to local regulations 
following completion of drug accountability procedures.
5.8 Randomization/Drug Assignment
All subjects will be assigned a unique identification number by the IRT at the screening visit.  For 
subjects who rescreen, the screening number assigned by the IRT at the initial screening visit should be 
used.  The IRT will assign a randomization number that will encode the subject's treatment group 
assignment according to the randomization schedule generated by the statistics department at AbbVie.  
Subjects in the study will be randomized in a 1:1 ratio to one of the 2 treatment groups:

Upadacitinib 15 mg QD

Upadacitinib 30 mg QD
The study will be stratified by Baseline vIGA-AD categories (3; 4) and prior use of dupilumab (yes; no).
IRT will provide the appropriate study drug kit number(s) to dispense to each subject.  Returned study 
drug must not be re-dispensed to any subject.
All AbbVie personnel with direct oversight of the conduct and management of the trial (apart from the 
AbbVie Drug Supply Management Team), the investigator, study site personnel, and the subject will 
remain blinded to each subject's treatment through Week 12.  After Week 12, the subject will be 
blinded to the upadacitinib dose they will receive.
Blinding of Investigational Product
During the 12-week double-blind period, study sites and subjects will remain blinded.  During the single 
blind period, only the subjects will be blinded to the upadacitinib dose and the EASI score evaluations.  
In order to maintain the blind, the upadacitinib tablets provided for the study will be identical in 
appearance.  The IRT will provide access to unblinded subject treatment information in the case of 
medical emergency.
In the event of a medical emergency that requires unblinding of the study drug assignment, the 
investigator is requested to contact the AbbVie TA MD prior to breaking the blind.  However, if an 
urgent therapeutic intervention is necessary which warrants breaking the blind prior to contacting the 
AbbVie TA MD, the investigator can directly access the IRT system to break the blind without AbbVie 
notification or agreement.  Unblinding is available in the IRT system via the Unblind Subject transaction, 
which is available only to the investigator.  If the IRT system is unavailable, unblinding may occur by 
contacting technical support via either phone (preferred) or email.
In the event that the blind is broken before notification to the AbbVie Therapeutic Area Medical Director 
(TA MD), we request that the AbbVie TA MD be notified within 24 hours of the blind being broken.  The 
date and reason that the blind was broken must be conveyed to AbbVie and recorded on the 
appropriate eCRF.

CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
5.9 Protocol Deviations
AbbVie does not allow intentional/prospective deviations from the protocol except when necessary to 
eliminate an immediate hazard to study subjects.  The investigator is responsible for complying with all 
protocol requirements, written instructions, and applicable laws regarding protocol deviations.  If a 
protocol deviation occurs (or is identified, including those that may be due to the COVID-19 pandemic), 
the investigator is responsible for notifying the independent ethics committee (IEC)/independent review 
board (IRB), regulatory authorities (as applicable by local requirements), and AbbVie.
In Japan, the investigator will record all protocol deviations in the appropriate medical records at site.
5.10 Data Monitoring Committee
Given no subjects participating in the study will receive placebo or other active comparators, the 
causality of any AEs reported in the participants can be adequately assessed in the context of 
upadacitinib treatment.  The study team will monitor and evaluate any AEs to identify findings that 
could put the study participants at risk and then make clinical decisions regarding the study conduct, 
which could include modification or termination of the study.  This can adequately safeguard the 
participants.  Given the above, it is not necessary to implement an independent Data Monitoring 
Committee for the conduct of this study.
5.11 Publication Policy
AbbVie as the sponsor has proprietary interest in this study. Authorship and manuscript composition will 
reflect joint cooperation between multiple investigators and sites and sponsor personnel. Authorship 
will be established prior to the writing of the manuscript. As this study involves multiple centers, no 
individual publications will be allowed prior to completion of the final clinical study report of the 
multicenter study except as agreed with the sponsor.
The sponsor will comply with the requirements for publication of study results. In accordance with 
standard editorial and ethical practice, the sponsor will generally support publication of multicenter 
studies only in their entirety and not as individual site data.
Investigators are NOT employed by the organization sponsoring the study. There is an agreement 
between investigators and the sponsor (or its agents) that restricts the investigator's rights to discuss or 
publish study results after the study is completed.
AbbVie requests that any investigator or institution that plans on presenting/publishing results, provide 
written notification of their request 60 days prior to their presentation/publication. AbbVie requests 
that no presentation/publication will be instituted until 12 months after a study is completed or after 
the first presentation/publication, whichever occurs first. A delay may be proposed for a 
presentation/publication if AbbVie needs to secure patent or proprietary protection.

5.12 Paper Diary Cards for Sites in China Only
For sites in China only, a paper diary card will be provided to subjects.  Subjects will be trained on how 
to complete the diary cards by site staff.  If subjects require re-training during the study, the site staff 
will accommodate this requirement.
All subjects should complete their paper diary cards until completion of the study.  Subjects will be 
instructed to bring their paper diary cards back to the site to be reviewed and collected at each visit, 
including at any visit at which a dose level change may be required.  If COVID-19 circumstances warrant 
a virtual visit, diary cards should be reviewed virtually with the subject and the site should collect the 
paper diary card at the next onsite visit.  Subjects will be instructed to record the date and time each 
dose of study drug is taken, indicating if any doses of study drugs are missed.
Subjects will also be instructed to record AE symptoms and concomitant medications in the paper diary 
cards.  At each visit, the paper diary cards are to be reviewed by the investigator, assessed for any 
updates needed, and collected from the subject by study staff.  Relevant information will be recorded in 
existing AE, drug administration, and concomitant medication forms in the eCRF as applicable.  At each
visit after the paper diary card is initially dispensed, including the final/PD Visit, the paper diary cards are 
to be returned to the site and appropriately filed with the subject's source documents for this study.  At 
each visit after the paper diary card is initially dispensed (except the final/PD Visit), the subject will be 
provided with a new diary card.
In case of missing diary card information, or when discrepancies are discovered, site personnel should 
discuss with the subject and document changes to data in site records forms and eCRFs, if applicable.  
The need for completion of the paper diary card will be reinforced with the subject during study visits, 
as necessary, by the site personnel.

CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
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.
Reporting will be done via electronic data capture (EDC).  The date the product complaint details are 
entered into EDC and the form is saved represents the date reported to AbbVie.  A back-up paper form 
will be provided for reporting complaints related to unassigned product or in the event of an EDC system 
issue.  If a back-up paper form is used, the date the form is emailed to RD_PQC_QA@abbvie.com 
represents the date reported to AbbVie.
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 AEs will be 
reported in the study summary.  All other complaints will be monitored on an ongoing basis.  Product 
complaints occurring during the study will be followed up to a satisfactory conclusion.
Medical Complaints/Adverse Events and Serious Adverse Events:  Upadacitinib
An 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 AE 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 
"special situations" such as accidental or intentional overdose, medication error, occupational or 
accidental exposure, off-label use, drug abuse, drug misuse, or drug withdrawal, all which must be 
reported whether associated with an AE or not.  Any worsening of a pre-existing condition or illness is 
considered an AE.  Worsening in severity of a reported AE should be reported as a new AE.  Laboratory 
abnormalities and changes in vital signs are considered to be AEs only if they result in discontinuation 
from the study, necessitate therapeutic medical intervention, meet protocol-specific criteria (see 
Section 6.2 regarding toxicity management), and/or if the investigator considers them to be AEs.
The investigators will monitor each subject for clinical and laboratory evidence of AEs on a routine basis 
throughout the study.  All AEs will be followed to a satisfactory conclusion.
An elective surgery/procedure scheduled to occur during a study will not be considered an AE if the 
surgery/procedure is being performed for a pre-existing condition and/or 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 AE.
If any of the following events are reported, then the following supplemental report must be completed.

CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
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.
All adverse events reported from the time of study drug administration until 30 days after 
discontinuation of study drug administration will be collected, whether solicited or spontaneously 
reported by the subject.  After 30 days following the last dose of study drug, only spontaneously 
reported SAEs will be collected (nonserious AEs will not be collected).  In addition, study 
procedure-related serious and nonserious adverse events will be collected from the time the subject 
signs the study-specific informed consent.
If a subject prematurely discontinues study participation and begins commercially available upadacitinib 
(Rinvoq), all AEs reported by healthcare professionals or the patient will be captured as post-marketing 
reports.  The 30-day follow-up phone call following the last dose of upadacitinib study drug during the 
study will not occur for subjects who begin commercially available upadacitinib.
The following definitions will be used for Serious Adverse Reactions (SAR) and Suspected Unexpected 
Serious Adverse Reaction (SUSAR):
SAR
Defined as all noxious and unintended responses to an IMP related to any dose 
administered that result in an SAE as defined above.
SUSAR
Refers to individual SAE case reports from clinical trials where a causal 
relationship between the SAE and the IMP was suspected by either the sponsor 
or the investigator, is unexpected (not listed in the applicable Reference Safety 
Information), and meets one of the above serious criteria.
AbbVie will be responsible for SUSAR reporting for the IMP in accordance with global and local 
requirements, including reporting to Eudravigilance database in accordance with EU Clinical Trial 
Regulation 536/2014.

CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
Adverse events will be monitored throughout the study to identify any of special interest that may 
indicate a trend or risk to subjects.
Adverse Events of Special Interest
The following adverse events of special interest (AESIs) will be monitored during the study:

Serious infections;

Opportunistic infections;

Herpes zoster;

Active tuberculosis;

Malignancy (all types);

Anemia;

Neutropenia;

Lymphopenia;

Renal dysfunction;

Hepatic disorder;

Adjudicated GI perforations;

Adjudicated cardiovascular events (e.g., major adverse cardiovascular event [MACE]); and

Adjudicated embolic and thrombotic events (non-cardiac, non-CNS).

Fractures

Retinal detachment
Cardiovascular Adjudication Committee
An independent external committee of physician experts in cardiovascular adjudication will be utilized 
to assess potential cardiovascular and thromboembolic AEs in a blinded manner as defined by the 
Cardiovascular Adjudication Committee charter.
Gastrointestinal Perforation Adjudication Committee
An internal GI perforation committee will identify and adjudicate AEs of spontaneous GI perforation.  
The internal committee will be comprised of at least 2 gastroenterologists or physicians with 
appropriate expertise who are independent of the clinical study team and blinded to subject treatment 
assignments.  The committee's primary responsibility is to review potential events of GI perforation and 
adjudicate against a pre-specified case definition.  A separate GI perforation charter will be prepared 
outside of the protocol and will describe the case definition, procedures, roles, and responsibilities.

Adverse Event Severity and Relationship to Study Drug
Investigators will rate the severity of each AE according to the National Cancer Institute Common 
Terminology Criteria for Adverse Events (NCI CTCAE Version 5.0), which can be accessed at: 
https://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm.
If no specific grading criteria are provided for the reported event, then the event should be as follows:

Mild (Grade 1):  asymptomatic or mild symptoms; clinical or diagnostic observations only; 
intervention not indicated;

Moderate (Grade 2):  minimal, local or noninvasive intervention indicated; limiting age 
appropriate instrumental activities of daily living (ADL) (instrumental ADL refer to preparing 
meals, shopping for groceries or clothes, using the telephone, managing money, etc.);

Severe (Grade 3 - 5):

Grade 3: severe or medically significant but not immediately life-threatening; hospitalization 
or prolongation of hospitalization indicated; disabling; limiting self-care ADL (self-care ADL 
refers to bathing, dressing and undressing, feeding self, using the toilet, taking medications,
and not bedridden);

Grade 4: Life-threatening consequences; urgent intervention indicated;

Grade 5: Death related to AE.
The investigator will use the following definitions to assess the relationship of the AE 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 AE, pregnancy in a study subject must be reported to AbbVie within 24 hours after the site 
becomes aware of the pregnancy.  If a pregnancy occurs in a study subject information regarding the 
pregnancy and the outcome will be collected.
Female subjects should avoid pregnancy throughout the course of the study, starting with the Screening 
Visit through 30 days after the last study drug administration.  Results of a positive pregnancy test or 
confirmation of a pregnancy will be assessed starting with the Screening Visit through the final study

CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
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.
Recording of Adverse Event Symptoms on the Subject Paper Diary Cards
For sites in China only, subjects will be instructed to record AE symptoms on the subject paper diary 
cards (see Section 5.12, Paper Diary Cards for Sites in China Only, for description of paper diary cards).
6.2 Toxicity Management
The toxicity management of the AEs including AESIs consists of safety monitoring (review of AEs on an 
ongoing basis) and, if applicable, interruption of study drug dosing with appropriate clinical 
management and/or discontinuation of the subjects from study drug.  The management of specific AEs 
and laboratory parameters is described below.
Serious Infections:  Study drug should be interrupted if a subject develops a serious infection. A subject 
who develops a new infection during treatment with study drug should undergo prompt diagnostic 
testing appropriate for an immunocompromised subject. Study drug may be restarted once the 
infection has been successfully treated.  Subjects who develop active TB must be permanently 
discontinued from study drug. 
Herpes zoster:  If a subject develops herpes zoster, consider temporarily interrupting study drug until 
the episode resolves.
Gastrointestinal Perforation:  If a diagnosis of gastrointestinal perforation is confirmed (other than due 
to appendicitis or mechanical injury), the subject must be permanently discontinued from study drug.
Major cardiovascular event:  For subjects who develop a major cardiovascular event (MACE: acute 
myocardial infarction, stroke) while on study drug, the investigator should evaluate the benefit/risk of, 
and discuss with the TA MD, whether it is appropriate to continue study drug.
Malignancy:  Subjects who develop malignancy other than localized NMSC or carcinoma in situ of the 
cervix must be permanently discontinued from study drug.  Information including histopathological 
results should be queried for confirmation of the diagnosis.  Periodic skin examination is recommended 
for subjects who are at increased risk for skin cancer.  Subjects who develop malignancies should be 
referred to appropriate specialists and managed as per standard of care.
Muscle-related symptoms:  If a subject experiences symptoms suggestive of myositis or 
rhabdomyolysis, consider checking CPK and aldolase with clinical management and/or study drug 
interruption as deemed appropriate by the investigator.
Thrombosis Events:  Subjects who develop symptoms of thrombosis should be promptly evaluated and 
treated appropriately.  If the diagnosis of deep vein thrombosis (DVT), pulmonary embolus or non-
cardiac, non-neurologic arterial thrombosis is confirmed, the subject must be discontinued from study 
drug.

CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
COVID-19:  Interrupt study drug in subjects with a confirmed diagnosis of COVID-19.  Consider 
interrupting study drug in subjects with signs and/or symptoms and suspicion of COVID-19.  Study drug 
may be restarted if fever is resolved without use of antipyretics for 24 hours and other symptoms 
improved, or if 5 days have passed since the COVID-19 positive test result (whichever comes last). The 
COVID-19 eCRF must be completed.
Management of Select Laboratory Abnormalities:  For any given laboratory abnormality, the 
investigator should assess the subject, apply the standard of care for medical evaluation and treatment 
following any local guidelines.  Specific toxicity management guidelines for abnormal laboratory values 
are described in Table 3, and may require a supplemental eCRF to be completed.  For subjects with 
ongoing laboratory abnormalities which require data entry into an eCRF, an additional eCRF related to 
subsequent laboratory abnormalities is only required if the subject has relevant changes in history (e.g., 
new onset signs or symptoms) or laboratory values which have returned to normal reference range or 
its Baseline value followed by subsequent laboratory abnormalities meeting toxicity guidelines 
(considered a new event).  All abnormal laboratory tests that are considered clinically significant by the 
investigator will be followed to a satisfactory resolution.  If a repeat test is required per Table 3, the 
repeat testing is to occur as soon as possible.
Table 3.
Specific Toxicity Management Guidelines for Abnormal Laboratory Values
Laboratory Parameter
Toxicity Management Guideline
Hemoglobin

If hemoglobin < 8 g/dL interrupt study drug dosing and confirm by 
repeat testing with a new sample.  If confirmed, continue to withhold 
study drug until hemoglobin value returns to ≥ 8 g/dL.
OR

If hemoglobin decreases ≥ 3.0 g/dL from Baseline without an 
alternative etiology, interrupt study drug dosing and confirm by 
repeat testing with new sample.

If hemoglobin decreases ≥ 3.0 g/dL from Baseline and an 
alternative etiology is known or the hemoglobin value remains in 
the normal reference range, the subject may remain on study 
drug at the investigator's discretion.

If confirmed, continue to withhold study drug until hemoglobin 
value returns to within 3.0 g/dL from Baseline.
Absolute neutrophil count 
(ANC)

If confirmed < 1000/μL by repeat testing with new sample, interrupt 
study drug dosing until ANC value returns to ≥ 1000/μL.

For confirmed < 500/μL, if value returns to ≥ 1000/μL, restarting study 
drug is allowed if there is an alternative etiology identified; 
documentation should include reason that rechallenge is expected to 
be safe for the subject.  Study drug should be discontinued if no 
alternative etiology can be found.
Absolute lymphocyte counts 
(ALC)

If confirmed < 500/μL by repeat testing with new sample, interrupt 
study drug dosing until ALC returns to ≥ 500/μL.  
Total white blood cell count

If confirmed < 2000/μL by repeat testing with new sample, interrupt 
study drug dosing until white blood cell count returns to ≥2000/μL.

Laboratory Parameter
Toxicity Management Guideline
AST or ALT
Interrupt study drug if any of the following scenarios are confirmed by repeat 
testing of AST/ALT:

ALT or AST > 3 × ULN and either a total bilirubin > 2 × ULN or an 
international normalized ratio (INR) > 1.5:

A separate blood sample for INR testing will be needed to 
measure INR at the time of repeat testing for ALT or AST.  A 
repeat test of INR is not needed for determination if above 
toxicity management criteria are met.

If a creatine phosphokinase (CPK) value is not available, a CPK 
should be drawn to exclude AST/ALT elevations related to muscle 
injury.

ALT or AST > 3 × ULN along with new appearance of fatigue, nausea, 
vomiting, right upper quadrant pain or tenderness, fever, rash, and/or 
new-onset eosinophilia.

ALT or AST > 5 × ULN for more than 2 weeks.
If ALT or AST > 8 × ULN, interrupt study drug immediately, repeat testing with a 
new sample, and if repeat test confirms result, contact the TA MD.
Subjects with HBc Ab+ (irrespective of HBs Ab status) and negative HBV DNA 
PCR testing at Screening who develop the following laboratory findings should 
have HBV DNA PCR testing performed within 1 week (based on initial elevated 
value):

ALT> 5 × ULN OR 

ALT or AST > 3 × ULN if an alternative cause is not readily identified.
A separate blood sample for HBV DNA PCR testing will be needed at the time 
of repeat testing for ALT or AST. 
A positive result for HBV DNA PCR testing will require immediate interruption 
of study drug (unless not acceptable by local practices).  Within one week of 
the first episode of a positive HBV DNA PCR test, a hepatologist consultation 
should occur for recommendation regarding subsequent treatment. 
Subjects who meet any of the above criteria should be evaluated for an 
alternative etiology of the ALT or AST elevation and managed as medically 
appropriate.  If applicable, the alternative etiology should be documented in 
the eCRF.  If ALT or AST values return to the normal reference range or its 
Baseline value, study drug may be restarted.  If restarting study drug, 
documentation should include reason that rechallenge is expected to be safe.  
If after clinically appropriate evaluation, no alternative etiology for ALT or AST 
elevation is found or the ALT or AST elevation has not resolved or is not 
trending down toward normal, the subject should be discontinued from study 
drug. 
For any confirmed ALT or AST elevations > 3 ULN, complete the appropriate 
supplemental hepatic eCRF(s).

Laboratory Parameter
Toxicity Management Guideline
Serum Creatinine
If serum creatinine is > 1.5 × the Baseline value and > ULN, repeat the test for 
serum creatinine (with subject in an euvolemic state) to confirm the results.  If 
the results of the repeat testing still meet this criterion, interrupt study drug 
and re-start study drug once serum creatinine returns to ≤ 1.5 x Baseline value.
For the above serum creatinine elevation scenario, complete the appropriate 
supplemental renal eCRF(s).

DNA = deoxyribonucleic acid; eCRF = electronic case report form; HBc Ab+ = Hepatitis B core antibody positive; HBs 
Ab = Hepatitis B surface antibody; HBV = Hepatitis B virus; INR = international normalized ratio; OR = odds ratio; 
PCR = Polymerase chain reaction; TA MD = Therapeutic Area Medical Director; ULN = upper limit of normal
Elective and Emergency Surgeries
For elective and emergency surgeries the following rules will apply:

If the subject must undergo emergency surgery, the study drug should be interrupted at the 
time of the surgery.  After emergency surgery, allow reintroduction of study drug once the 
physician has examined the surgical site and determined that it has healed and there is no sign 
of infection.

Elective surgery, and interruption of study drug for such a surgery, will not be allowed during 
the study until the primary endpoint has been assessed (Week 24).  If elective surgery is 
considered prior to the primary endpoint visit (Week 24), it must be discussed with the TA MD 
and performed with TA MD approval. If the subject undergoes elective surgery, the study drug 
should be interrupted at least 1 week prior to the planned surgery.  Allow reintroduction of 
study drug once the physician has examined the surgical site and determined that it has healed 
and there is no sign of infection.
6.3 Other Safety Data Collection
Specific manifestations of AD (i.e., itching, excoriations, oozing, crusting, erythema, etc.) should not be 
reported as individual AEs if they are considered to be a worsening of the underlying disease; instead, 
worsening of AD should be reported as an AE.

Categorical endpoints will be summarized by counts and percentages, as well as 95% confidence interval 
(CI) of the percentage.  Continuous variables will be summarized by the number of observations, mean, 
standard deviation, median, minimum, maximum, and well as 95% confidence intervals (CIs) of the 
mean values.
The primary approach for efficacy summary is As Observed (AO). 
Summary and Analysis of the Primary Endpoint
The primary endpoint will be summarized in the ITT_2_SS1 and ITT_2_SS2 Populations by counts and 
percentages, as well as the 95% CIs of the percentage.  The AO approach will be used as the primary 
approach.
Sensitivity analyses of the primary endpoint will be conducted.  The primary endpoint will be 
summarized using the Multiple Imputation (MI) to handle missing data.  The details will be specified in 
the SAP.
Summary and Analysis of Secondary Endpoints
Summary of the secondary efficacy endpoints will be conducted using the ITT Populations with the 
treatment as randomized.  Categorical variables will be summarized by counts and percentages, as well 
as 95% CIs of the percentage.  The AO approach will be used.

7.5 Statistical Analyses for Safety
The safety analyses will be summarized in the double-blind period, single-blind period, and across study 
periods by the upadacitinib doses, based on the Safety_1_SS1 and Safety_1_SS2 Populations, 
Safety_2_SS1 and Safety_2_SS2 Populations, and ALL_UPA Population, respectively.
Safety will be assessed by AEs, physical examination, laboratory assessments, and vital signs.  Note that 
missing safety data will not be imputed.  Analysis details will be specified in the SAP.  Adverse events will 
be coded using the Medical Dictionary for Regulatory Activities (MedDRA).  Treatment-emergent AEs in 
each period are defined as those that began or worsened in severity after the first dose of study drug in 
each period and up to the minimum of the end date of each period and 30 days after the last dose of the 
study drug in each period.  The number and percentage of subjects experiencing TEAEs in each period

and across study periods by the upadacitinib doses will be tabulated using the MedDRA SOC and PT, by 
severity, and by relationship to the study drug as assessed by the investigator.  Summaries (including 
number of subjects, percentages and events per 100 patient-years) of SAEs, deaths, AEs leading to 
discontinuation, and AESI will be provided in each period and across study periods by the upadacitinib 
doses as well.
For laboratory and vital signs, mean change from Baseline will be summarized in each period and 
percentage of subject with evaluations meeting criteria for pre-defined Potentially Clinically Significant 
values will be summarized in each period and across study periods by the upadacitinib doses.  For 
selected laboratory parameters, a shift table analysis will be provided in each period and across study 
periods by the upadacitinib doses.
7.6 Sample Size Determination
Assuming:

In SS1, 54% of subjects would be EASI 90 non-responders at Week 12.

In SS2, 65% of the subjects would be EASI 90 responders at Week 12.

There would be no more than 8% dropouts every 12 weeks.
A total sample size of 454 subjects will result in at least 96 subjects in SC1 and SC4, to ensure the half 
width of 95% CI will be within 10% for EASI 90 response estimation at Week 24.

Introduction
This Statistical Analysis Plan (SAP) describes the statistical analyses for ABT-494 
Study M22-000 (Flex-Up) "A Phase 3b/4 Randomized, Blinded, Treat-to-Target and 
Dose-Flexibility Study of Upadacitinib in Adult Subjects with Moderate to Severe Atopic 
Dermatitis (Flex-Up)."
This study aims to provide descriptive data on the efficacy and safety of dose escalation to 
upadacitinib 30 mg once daily (QD) and dose reduction to upadacitinib 15 mg QD based 
on a clinical response after 12 weeks of treatment. This data will inform the clinical 
management for subjects with moderate to severe AD treated with both approved doses of 
upadacitinib.
The analyses of pharmacodynamic biomarker endpoints will not be covered in this SAP.
The SAP will not be updated in case of administrative changes or amendments to the 
protocol unless the changes impact the analysis.
Unless noted otherwise, all analyses will be performed using SAS Version 9.4 (SAS 
Institute Inc., Cary, NC  27513) or later under the UNIX operating system.
2.0
Study Objectives and Design
2.1
Study Objectives, Hypotheses and Estimands
The primary study objectives are:
1.
Sub-Study 1 (SS1):  The primary study objective for SS1 is to evaluate the 
efficacy and safety of dose escalation to upadacitinib 30 mg QD in subjects who 
do not achieve Eczema Area and Severity Index (EASI) 90 on upadacitinib 15 mg 
QD after 12 weeks.
2.
Sub-Study 2 (SS2):  The primary study objective for SS2 is to evaluate the 
efficacy and safety of dose reduction to upadacitinib 15 mg QD in subjects who 
achieve EASI 90 on upadacitinib 30 mg QD after 12 weeks.


Upadacitinib
M22-000 – Statistical Analysis Plan
Version 2.0 – 27 August 2024

The additional objective is to generate evidence on patient impact (patient reported 
outcomes [PROs]) with upadacitinib treatment based on a clinical response target 
(EASI 90) (Treat-to-Target).
No hypothesis testing will be performed in this study.
The estimand corresponding to the primary endpoint is defined as:
●
The proportion of subjects who achieve EASI 90 at Week 24, regardless of 
treatment discontinuation, with upadacitinib treatments (upadacitinib 15 mg or 
30 mg QD) in adult subjects with moderate to severe AD.
2.2
Study Design Overview
This is a Phase 3b/4, randomized, blinded, treat-to-target, dose-flexibility, multi-center 
study that will evaluate upadacitinib, as monotherapy, in approximately 454 adult subjects 
(≥ 18 and < 65 years of age) with moderate to severe AD who are candidates for systemic 
therapy.
The study is comprised of a 35-day Screening Period, a 12-week double-blind period and 
a 12-week single-blind period. During the single-blind period, subjects will be blinded to 
the upadacitinib dose and EASI score evaluations.
The study treatment duration will be 24 weeks.
After the last study visit, a 30-day follow-up visit (or phone call if a visit is not possible) 
will be completed to determine the status of any new or ongoing AEs/SAEs and 
concomitant medications.
Subjects who meet the eligibility criteria will be randomized in a 1:1 ratio to enter SS1 to
receive oral doses of upadacitinib 15 mg QD at Baseline or SS2 to receive oral doses of 
upadacitinib 30 mg QD at Baseline.

●
SS1:
○
Subjects randomized to enter the SS1 at Baseline will receive oral doses of 
upadacitinib 15 mg QD during the 12-week double-blind period.
○
At Week 12, subjects from SS1 receiving upadacitinib 15 mg QD will be 
reassigned based on their EASI response, which is calculated based on the 
observed EASI value regardless of use of rescue medications:
●
Subjects achieving a < 90% reduction in EASI (< EASI 90) will be 
allocated to receive oral doses of upadacitinib 30 mg QD. This 
constitutes the Study Cohort 1 (SC1).
●
Subjects achieving a ≥ 90% reduction in EASI (≥ EASI 90) will 
continue to receive oral doses of upadacitinib 15 mg QD. This 
constitutes the Study Cohort 2 (SC2).
●
SS2:
○
Subjects randomized to enter SS2 at Baseline will receive oral doses of 
upadacitinib 30 mg QD during the 12-week double-blind period.
○
At Week 12, subjects from SS2 receiving upadacitinib 30 mg QD will be 
reassigned based on their EASI response, which is calculated based on the 
observed EASI value regardless of use of rescue medications:
●
Subjects achieving < EASI 90 will continue to receive oral doses of 
upadacitinib 30 mg QD. This constitutes the Study Cohort 3 (SC3).
●
Subjects achieving ≥ EASI 90 will be allocated to receive oral doses of 
upadacitinib 15 mg QD. This constitutes the Study Cohort 4 (SC4).
The final and only database lock will occur at the end of the study.
The schematic of the study is shown in Figure 1.

2.3
Treatment Assignment and Blinding
All subjects will be assigned a unique identification number by the IRT at the screening 
visit. For subjects who rescreen, the screening number assigned by the IRT at the initial 
screening visit should be used. The IRT will assign a randomization number that will 
encode the subject's treatment group assignment according to the randomization schedule 
generated by the statistics department at AbbVie. Subjects in the study will be randomized 
in a 1:1 ratio to one of the 2 treatment groups:
●
Upadacitinib 15 mg QD
●
Upadacitinib 30 mg QD
The study will be stratified by Baseline vIGA-AD categories (3; 4) and prior use of 
dupilumab (yes; no).


Upadacitinib
M22-000 – Statistical Analysis Plan
Version 2.0 – 27 August 2024

During the 12-week double-blind period, study sites and subjects will remain blinded. 
During the single blind period, only the subjects will be blinded to the upadacitinib dose 
and the EASI score evaluations. 
2.4
Sample Size Determination
By Assuming:
●
In SS1, 54% of subjects would be EASI 90 non-responder at Week 12.
●
In SS2, 65% of the subjects would be EASI 90 responder at Week 12.
●
There would be no more than 8% dropouts every 12 weeks.
A total sample size of 454 subjects will result in at least 96 subjects in SC1 and SC4, to 
ensure the half width of 95% CI will be within 10% for EASI 90 response estimation at 
Week 24.

Efficacy Analyses
9.1
General Considerations
The efficacy analysis will be conducted in the ITT 1 and ITT 2 Populations in DB Period 
and SB Period descriptively and no statistical testing will be performed in this study.
Categorical endpoints will be summarized by counts and percentages, as well as 95% 
confidence interval (CI) of the percentage. Continuous variables will be analyzed by the 
number of observations, mean, standard deviation, median, minimum, maximum, as well 
as 95% confidence intervals (CIs) of the mean values. The primary missing data handling 
approach for efficacy summary is As Observed (AO).

9.2
Handling of Missing Data
All efficacy endpoints will be analyzed using AO approach:
●
The AO analysis will not impute values for missing evaluations, and thus a 
subject who does not have an evaluation at a scheduled visit will not be 
included in the AO analysis for that visit.
Another missing data handling method performed as a sensitivity analysis for the primary 
endpoint only is Multiple Imputation (MI) approach, which defined as below:
●
MI approach: Markov Chain Monte Carlo (MCMC) will be first applied to 
augment data into monotonic missing pattern and PROC MI will be used to 
generate 30 datasets using the regression method. The imputation is done in 
two steps for the primary endpoint.
Step 1: Missing EASI scores will be imputed. The variables to be included in the 
imputation model are treatment groups, actual stratification factors (vIGA-AD categories 
(3; 4) and prior use of dupilumab (yes; no)), baseline, and measurements at each visit. The 
random seed for MCMC and the random seed for PROC MI are set as 1005 and 9015. 
The imputed post-baseline measurements will be rounded to the same precision as the 
observed data before the determination of responder status.
Step 2: After obtaining the EASI 90 at Week 24 based on MI imputed values, subjects 
will be characterized as responders or non-responders based on MI imputed datasets. The 
primary endpoint will be analyzed using each of the 30 datasets. SAS PROC 
MIANALYZE will be used to generate the final inferences of the EASI 90 percentages, 
the standard errors as well as 95% CIs.

Analysis of Daily Efficacy Measurement
For daily efficacy assessments of the Worst Pruritus NRS, ADerm-IS sleep domain, and 
ADerm-SS skin pain, a rolling weekly average is calculated by using handheld device 
only to represent the corresponding endpoints by week in DB Period and SB Period.
The weekly average of the daily values from a maximum of 7 days immediately prior to 
the first dose date will be used as the Baseline value. The rolling weekly average score is 
calculated for each Day m, starting from Day 8 through the Week 24 visit as follows. Let 
Pm-6, Pm-5, …, Pm-1, Pm be the daily score from Day m
6 to Day m, and Nm be the number 
of days with non-missing scores from Day m
6 to Day m, then the rolling weekly 
average for Day m is:
If the values from four or more days of the 7-day period are missing, then the rolling 
weekly average of Day m will be set to missing. If more than one assessment is included 
on the same day, the assessment associated with the worst condition on that day will be 
chosen as the daily score. Analysis value for a given visit will be selected from rolling 
averages based on analysis window conventions.

Adverse Events
The summaries of adverse events will be provided by treatment groups in DB Period for 
Safety 1 Population, in SB Period for Safety 2 Population, and during the administration 
of upadacitinib for All UPA Population.
10.2.1
Treatment-Emergent Adverse Events
Treatment-emergent adverse events (TEAEs) are defined as follows:
●
TEAEs in DB Period are defined as any adverse events that begin or worsen in 
severity after initiation of upadacitinib through the minimum (30 days 
following the last dose of upadacitinib in DB Period, or the start day of SB 
Period  1).
●
TEAEs in SB Period are defined as any adverse events that begin or worsen in 
severity after initiation of upadacitinib in SB Period through 30 days following 
the last dose of upadacitinib in SB Period.
●
TEAEs during the administration of upadacitinib are defined as any adverse 
events that begin or worsen in severity after initiation of upadacitinib through 
30 days following the last dose of upadacitinib.
If a missing or an incomplete onset date is collected for an adverse event, the event will be 
assumed to be treatment-emergent unless there is other evidence that confirms that the 
event is not treatment-emergent (e.g., the event end date is prior to the study drug start 
date). Events where the onset date is the same as the study treatment start date are 
assumed to be treatment-emergent.
All TEAEs will be summarized overall, as well as by primary MedDRA SOC and 
Preferred Term. The SOCs will be presented in alphabetical order, and the PTs will be 
presented in alphabetical order within each SOC.

The number and percentage of subjects experiencing TEAEs and the number of events per 
100 patient-years of exposure will be summarized.
TEAEs per 100 patient-years of exposure are defined as the number of TEAEs divided by 
the total exposure in 100 patient-years. See the calculation method below:
100 * (Number of TEAEs) / (Total Patient Years)
where total patient years is defined as the sum of the study drug duration (defined in 
Section 6.0) of all subjects normalized by 365.25 and rounded to 1 decimal place.

Treatment-Emergent Adverse Events by SOC and/or PT
TEAEs will be summarized and presented using primary MedDRA version 26.0 by 
system organ class (SOC) and preferred terms (PT); by maximum relationship to study 
drug as assessed by the investigator (e.g., reasonable possibility or no reasonable 
possibility) and SOC and PT; by maximum toxicity and SOC and PT. The SOCs will be 
presented in alphabetical order, and the PTs will be presented in alphabetical order within 
each SOC. Subjects reporting more than one adverse event for a given MedDRA preferred 
term will be counted only once for that term (most severe incident for the toxicity tables 
and most related incident for the relationship tables). A subject who reports more than 
1 AE in different SOCs will be counted only once in the overall total. Subjects reporting 
more than one type of adverse event will be counted only once in the overall total. If the 
same adverse event occurs multiple times within a subject, the highest severity and level 
of relationship to investigational product will be reported.
The following summaries of adverse events will be generated:

For summaries of AEs by toxicity, each subject is counted only once 
according to the 
maximum toxicity level observed. If a subject has an AE with an unknown toxicity, then 
the subject will be counted in the toxicity category of "unknown." The only exception is 
that if the subject has another occurrence of the same AE with the most extreme, non-fatal 
NCI CTCAE toxicity (i.e., grade 4) or is fatal (grade 5). In this case, the subject will be 
counted under grade 4 if non-fatal or 5 if fatal. For tables that look at severity instead of

Analysis of Laboratory Data
Data collected from central and local laboratories, including additional laboratory testing 
due to an SAE, will be used in all analyses, except for Baseline where SAE-related 
laboratory assessments on or before the first dose of study drug will be excluded. The 
clinical laboratory tests defined in the protocol operations manual (e.g., hematology and 
clinical chemistry) will be summarized.
For the analysis of laboratory data, values observed up to 30 days after the last dose of 
upadacitinib will be included.
Analysis of Quantitative Laboratory Parameters (Hematology, Chemistry and 
Urinalysis)
Raw values and change from Baseline (percent change if applicable) to each applicable 
post-baseline visit will be summarized for selected laboratory variables in the Safety 1 
and Safety 2 Populations. At each visit, the following descriptive statistics will be 
presented by treatment groups: number of observations, Baseline mean (Standard 
deviation, SD), visit mean (SD), medium, change from Baseline mean (SD), standard 
error, and the 95% confidence interval of the mean change from Baseline.
Shift Table Analyses
Selected laboratory parameters will be tabulated using shift tables from Baseline to the 
worst value by NCI CTCAE in DB Period for the Safety 1, in SB Period for the Safety 2 
Population and during the administration of upadacitinib for the All UPA Population. 


Upadacitinib
M22-000 – Statistical Analysis Plan
Version 2.0 – 27 August 2024
33
Selected lipid parameters will be summarized using National Cholesterol Education 
Program (NCEP) Adult Treatment Panel III (ATPIII) guidelines and details can be found 
in Appendix E. Similar shift tables will be provided to summarize shifts from Baseline to 
the final post-baseline value in DB Period for the Safety 1, in SB Period for the Safety 2 
Population and during the administration of upadacitinib for the All UPA Population. 
Here, the Upadacitinib Baseline is defined as the last observation prior to the first dose of 
upadacitinib. The criteria in shift table are defined using CTCAE 4.03. 
Potentially Clinically Important Laboratory Values
Laboratory abnormalities will be evaluated based on Potentially Clinically Important 
(PCI) criteria (NCI CTCAE V4.03 criteria of Grade 3 or above) in DB Period for the 
Safety 1, in SB Period for the Safety 2 Population and during the administration of 
upadacitinib for the All UPA Population. 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. The PCI criteria are defined in Appendix D using CTCAE 
4.03.
Liver Function Tests
For the purpose of assessing for potential Hy's law cases, the frequencies and percentages 
of subjects with post-baseline liver function test values that meet the PCI criteria (defined 
in Appendix D) will be presented in DB Period for the Safety 1 Population, in SB Period 
for the Safety 2 Population and during the administration of upadacitinib for the 
ALL UPA Population. A listing of possible Hy's Law cases will be provided.
10.4
Analysis of Vital Signs
Vital sign measurements of systolic and diastolic blood pressure, pulse rate, respiratory 
rate and body temperature will be summarized.


Upadacitinib
M22-000 – Statistical Analysis Plan
Version 2.0 – 27 August 2024
34
Each vital sign variable will be summarized for all time points (starting with Baseline) 
with the number of non-missing observations, mean and standard deviation, median, 
minimum and maximum. Mean change from Baseline to each applicable post-baseline 
visit in both DB Period and SB Period 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 within each treatment group in Safety 1 and Safety 2 
Populations.
Vital sign variables will be evaluated based on potentially clinically important (PCI) 
criteria (Appendix D) for the Safety 1, Safety 2 and the ALL UPA Population. For each 
vital signs PCI criterion, the number and percentage of subjects who have at least one 
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.

Data Monitoring Committee
Given no subjects participating in the study will receive placebo or other active 
comparators, the causality of any AEs reported in the participants can be adequately 
assessed in the context of upadacitinib treatment. The study team will monitor and 
evaluate any AEs to identify findings that could put the study participants at risk and then 
make clinical decisions regarding the study conduct, which could include modification or 
termination of the study. This can adequately safeguard the participants. Given the above, 
it is not necessary to implement an independent Data Monitoring Committee for the 
conduct of this study.
