Start date: 2021-06-30; Completion date: 2023-08-29
Enrollment: 185 participants; Allocation: RANDOMIZED; Intervention model: PARALLEL

Brief summary:
Vitiligo is a common chronic autoimmune disease that causes the body's immune system to attack its own pigment producing skin cells. This study is to evaluate how safe and effective upadacitinib is in participants with non-segmental vitiligo. Adverse effects and change in disease activity will be assessed.

Upadacitinib is being evaluated for the treatment of non-segmental vitiligo. The study will enroll approximately 160 participants aged 18-65 with non-segmental vitiligo in 5 treatment arms across 35 sites worldwide.

Participants will either receive study drug vs placebo oral tablets once daily (QD) for 24 weeks (Period A). In Period B (up to 52 weeks), participants who received placebo during the first 24 weeks will switch to study drug. Participants who received study drug during the first 24 weeks, will continue to receive study drug.

There may be higher treatment burden for participants in this trial compared to their standard of care. 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 upadacitinib 22 mg administered orally once a day (QD) as tablets for 24 weeks during Period 1. Participants then received upadacitinib 22 mg administered orally once a day (QD) as tablets for 28 weeks during Period 2. arm 2: Participants received upadacitinib 11 mg administered orally once a day (QD) as tablets for 24 weeks during Period 1.

2 INTRODUCTION
2.1 Background and Rationale
Why Is This Study Being Conducted?
Vitiligo is a common chronic autoimmune disorder of the skin characterized by depigmented skin lesions 
due to autoimmune-induced loss of melanocytes in the epidermis.1  The disease is associated with an 
impaired quality of life (QoL).2  There is no approved medical therapy for vitiligo re-pigmentation and 
current unapproved therapies have limited efficacy, emphasizing the need for improved treatment 
options.
The disease most commonly presents as white macules and patches of skin with equal impact on men 
and women.3  Vitiligo manifests as milky-white patches of pigment loss due to localized melanocyte 
destruction.  Early depigmentation typically occurs on the face and extremities.  In 2011, an 
international consensus classified vitiligo into segmental vitiligo and non-segmental vitiligo (NSV), with 
the majority of patients (> 90%) exhibiting the non-segmental variant.4  Segmental vitiligo refers to 
depigmented macules and patches distributed in a segmental or unilateral pattern, whereas NSV lesions 
are distributed bilaterally.4  In general, the term vitiligo is being used to describe all forms of NSV, which 
includes acrofacial, mucosal, generalized, universal, mixed, and rare variants.
The global prevalence of vitiligo is approximately 0.5% to 2%, and patients with vitiligo often have 
psychological and autoimmune comorbidities.2,5,6  Vitiligo has been associated with several 
auto-immune diseases such as thyroid disease (Hashimoto thyroiditis), psoriasis, rheumatoid arthritis 
(RA), alopecia areata, pernicious anemia, systemic lupus erythematosus, and diabetes mellitus.  It has 
also been associated with inflammatory bowel disease and sometimes ocular and audiological 
abnormalities.7,8  Although patients with vitiligo have a decreased risk of melanoma and non-melanoma 
skin cancer (NMSC),9,10 clinical practice recommends constant use of sunscreen due to the risks of 
sunburn from direct sunlight on depigmented skin.  Overall, the effect of vitiligo on QoL impairment 
seem to be associated with the distribution of vitiligo lesions (e.g., face, genital area) but also by the 
extent of the disease, highlighting the unmet need of effective systemic therapies.
There are few treatment options for vitiligo and these have limited efficacy.  Thus, there is a lack of 
options for patients with vitiligo, particularly those with severe manifestation of the disease, given the 
limited response to currently available topical and systemic therapies.
Impairment or death of melanocytes is believed to be the direct cause of vitiligo.  Melanocytes produce 
the pigment melanin, which colors the skin and provides protection from UV radiation.  While several 
theories describe vitiligo pathogenesis, the exact etiology is unknown. The autoimmune theory 
hypothesizes that interferon (IFN)-y is an important cytokine expressed in lesional skin and is required 
for the recruitment of melanocyte-specific, autoreactive CD8+ T cells to the skin via the chemokines 
CXCL9/10 and CXCR3.11,12  Cytotoxic CD8+ T cells are both necessary and sufficient for melanocyte 
destruction in the skin of vitiligo patients and therefore serve as the effector arm driving the 
autoimmunity of vitiligo.  The Janus kinase (JAK)/Signal Transducers and Activators of Transcription 
(STAT) pathway is therefore an attractive therapeutic target due to its direct effect on IFN-y and CXCL10 
levels.

CONFIDENTIAL INFORMATION

Evidence suggests that inhibition of JAK-mediated pathways may be a promising approach for the 
treatment of patients with vitiligo.13  Ruxolitinib (a JAK1/2 inhibitor), in a topical formulation, has 
demonstrated efficacy in treating patients with vitiligo in a Phase 2 study14 and is currently enrolling 
patients in two Phase 3 studies.15,16  AbbVie developed a JAK inhibitor, upadacitinib, which, when given 
systemically may address the current needs for patients with vitiligo.  Upadacitinib is a selective and 
reversible inhibitor of JAK1 that recently has received approval for the treatment of RA, psoriatic 
arthritis (PsA), and ankylosing spondylitis (AS) in some countries and is also being developed for the 
treatment of other immune-mediated inflammatory diseases, including dermatologic conditions such as 
atopic dermatitis (AD) and hidradenitis suppurativa.
Clinical Hypothesis
Vitiligo is a chronic autoimmune disorder of the skin characterized by an increase of proinflammatory 
cytokines involved in the JAK/STAT pathway.  Upadacitinib is predicted to provide better efficacy 
compared to placebo and to be well tolerated in vitiligo subjects.
2.2 Benefits and Risks to Subjects
Currently there are no approved medical therapies for skin re-pigmentation for patients with vitiligo and 
current unapproved therapies such as topical corticosteroids and calcineurin inhibitors have limited 
efficacy, indicating that there is a high unmet need.  Phototherapy is one of the most common therapies 
used for vitiligo; nonetheless, treatment can be burdensome to patients as it requires multiple and 
frequent visits to the office or home therapy and is associated with a high relapse rate within the first 
year upon discontinuation (average 40%), highlighting the need for long-lasting therapies.17
At this time, patients with significant vitiligo, including patients with rapidly progressive disease, are 
commonly treated with oral steroids which are not suitable for long-term use.
The efficacy of upadacitinib has shown promising results in various immune-mediated diseases including 
dermatologic conditions such as AD.18
Adverse events (AEs) such as infections, herpes zoster reactivation, malignancies, and hematologic AEs 
have been observed in patients receiving JAK inhibitors including upadacitinib.  The available long-term 
safety data from the Phase 3 RA studies with upadacitinib showed an increased risk of infection 
including opportunistic infections (e.g., mucosal candida infections) and herpes zoster, as well as 
abnormal laboratory changes have been observed (e.g., elevations of serum transaminases, lipids, 
creatine phosphokinase [CPK], and reductions in hemoglobin and white blood cells [WBCs]) with 
upadacitinib therapy.  The incidence rates of other clinically important AEs such as cardiovascular 
events, malignancies, and mortality reported during the RA studies were within the expected range for 
the general population or for a population of patients with moderately to severely active RA.19  Events of 
deep vein thrombosis (DVT) and pulmonary embolism have been reported in patients receiving JAK 
inhibitors including upadacitinib.  Similar findings of these important AEs were also observed in the 
clinical studies for other indications including PsA and AD.  AEs of acne have been observed more 
frequently with upadacitinib treatment versus placebo in Phase 3 PsA and AD studies.
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.19
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 including vitiligo.
In view of the coronavirus disease 2019 (COVID-19) pandemic, 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.

3.5 Safety Endpoints
Safety evaluations include AEs, serious adverse events (SAEs), adverse events of special interest (AESIs), 
AEs leading to discontinuation, vital signs, laboratory tests (hematology, chemistry, liver function tests), 
and physical examination.
3.6 Pharmacokinetic Endpoints
Pharmacokinetic (PK) samples will be obtained at specified clinic visits as noted in Appendix D.  
Upadacitinib plasma concentrations will be determined and summarized in the clinical study report.  In 
addition, a nonlinear mixed-effects modeling approach may be used to estimate the population central 
values and the empirical Bayesian estimates of the individual values of upadacitinib PK parameters (e.g., 
oral clearance [CL/F] and apparent volume of distribution [V/F]).  Data from this study may be combined 
with data from other studies for the population PK analyses.
3.7 Biomarker Research Endpoints
Optional samples for biomarker research (e.g., whole blood, plasma, serum, and skin biopsies) will be 
collected at specified time points (Activity Schedule, Appendix D) throughout the study to evaluate 
known and/or novel disease-related or drug-related biomarkers in circulation or at tissue sites.  Types of 
biomarkers may include nucleic acids, proteins, cell populations, lipids, and/or metabolites, either free 
or in association with particular cell types.  The analyses may include but are not limited to soluble 
proteins, genomic transcripts, blood leukocyte populations, and genetic analysis to evaluate biomarker 
endpoints related to safety, disease state, and target pathway.  Results from this optional biomarker 
research may not be included in the clinical study report.  Further details regarding the biomarker 
research rationale and collection time points are located in the operations manual, Appendix F, 
Section 3.12.
3.8 Exploratory and/or Validation Research
Digital Imaging
Validation of a 3-D digital imaging tool will be explored at a subset of sites to objectively quantify the 
surface area of vitiligo lesions (depigmentation) on the face with precision. Approximately 5 sites will be 
selected to participate in the digital imaging research. Once the digital imaging platform is available for 
implementation at the selected sites, all subjects enrolled thereafter will be required to participate. The 
results from these analyses are exploratory in nature and may not be included with the clinical study 
report.
Individual Component Vitiligo Assessment (ICVA)
The ICVA will be used to collect exploratory information regarding vitiligo involvement on the genitals 
and individual components of the face using 2 assessments:  Physician Global Vitiligo Assessment

4 INVESTIGATIONAL PLAN
4.1 Overall Study Design and Plan
This is a Phase 2, multicenter, randomized, double-blinded, parallel-group, placebo-controlled 
dose-ranging study that will evaluate the safety and efficacy of upadacitinib in adult subjects ≥ 18 to 
65 years of age with NSV.  The study is comprised of a 35-day Screening Period, a 24-week double-blind 
treatment period (Period 1), a 28-week blinded long-term extension (Period 2), and a 30-day Follow-up 
Period.
Subjects who meet eligibility criteria at Baseline will be randomized in a 2:2:2:1:1 ratio to one of five 
treatment groups:

Group 1:  upadacitinib 22 mg once daily (QD) (N = 40) (Period 1) → upadaciNnib 22 mg QD 
(Period 2)

Group 2:  upadacitinib 11 mg QD (N = 40) (Period 1) → upadaciNnib 11mg QD (Period 2)

Group 3:  upadacitinib 6 mg QD (N = 40) (Period 1) → upadaciNnib 6 mg QD (Period 2)

Group 4:  placebo (N = 20) (Period 1) → upadaciNnib 22 mg QD (Period 2)

Group 5:  placebo (N = 20) (Period 1) → upadaciNnib 11 mg QD (Period 2)
At Week 24, subjects who were randomized to placebo at Baseline will be switched to either 22 mg 
(Group 4) or 11 mg (Group 5) upadacitinib in a blinded fashion per pre-specified randomization 
assignments.
The AbbVie study team will be unblinded to perform the Week 24 primary analysis.  The unblinding will 
take place after all subjects have completed the Week 24 visit or have prematurely discontinued prior to 
Week 24.  Sites and subjects will remain blinded throughout the study.
Information on the Data Monitoring Committee (DMC) is described in Section 6.3.  Information on the 
Cardiovascular Adjudication Committee (CAC) and gastrointestinal (GI) perforation adjudication are 
described in Section 6.1.
See Section 5.1 for information regarding eligibility criteria and Section 5.8 for information on 
stratification.

4.2 Discussion of Study Design
Choice of Control Group
Placebo control will be used in this study.  Comparative studies utilizing a double-blind, 
placebo-controlled design provides an unbiased assessment of the efficacy and safety profile of 
upadacitinib.
Appropriateness of Measurements
Standard statistical, clinical, and laboratory procedures will be utilized in this study.  All efficacy 
measurements in this study are for assessing disease activity and patient-reported outcomes in subjects 
with vitiligo.  All safety-related 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 within the next 3 days if still within the visit window and after drinking plenty of fluids (1 L to 
2 L over a 24-hour period).
Suitability of Subject Population
The intended study population is adult subjects ≥ 18 to 65 years of age with NSV.  Subjects with 
documented clinical diagnosis of NSV and no segmental or localized vitiligo are eligible for this study.  At 
study entry, eligible subjects must have at least 0.5 F-VASI and at least 5 T-VASI.  Criteria relating to 
safety have been selected to allow subjects to be safely enrolled and treated with upadacitinib based on 
the current knowledge of this drug.
Selection of Doses in the Study
This study is designed as a dose-ranging study to evaluate upadacitinib doses of 6 mg, 11 mg, and 22 mg 
QD in adult subjects with vitiligo.  These doses were selected to provide comprehensive dose-ranging 
information in patients with vitiligo through evaluation of upadacitinib doses that have not been studied 
in other upadacitinib indications (e.g., RA, PsA, AS, and AD).
Patients with vitiligo generally present with a clinically (and biologically) different disease profile 
compared to previously studied indications for upadacitinib.  Although vitiligo significantly impairs QoL, 
it is generally considered an asymptomatic dermatosis (some patients may suffer from skin 
irritation/itching), and is usually associated with lower comorbidities, minimal background and 
concomitant therapies, and less heterogeneous signs and symptoms of the disease.  Hence, the 
upadacitinib dose(s) that may provide optimal benefit risk in patients with vitiligo are yet to be 
determined and may occur at dose levels that have not been previously explored for other indications.
Upadacitinib 15 mg QD and 30 mg QD doses showed significant clinical benefit for treatment of subjects 
with RA, PsA, AS, and AD in Phase 3 studies, with an added clinical benefit of 30 mg compared to 15 mg 
for some (e.g., AD) but not all (e.g., RA, PsA) indications.

CONFIDENTIAL INFORMATION

Two case studies have reported partial re-pigmentation of vitiligo white patches after administration of 
tofacitinib, a pan JAK-inhibitor, at a 5 mg twice a day dose together with narrowband UV-B therapy.20  
Although the observed response in these 2 case studies was achieved with a combination of tofacitinib 
and phototherapy, the findings suggest that JAK inhibition with dose levels comparable to efficacious 
doses in RA and PsA populations may provide clinical efficacy in patients with vitiligo.  Whether lower or 
higher doses could provide similar or higher efficacy, respectively, remains unclear and requires more 
data from adequate dose-ranging studies in patients with vitiligo.
Hence, upadacitinib doses of 11 mg and 22 mg have been selected to allow evaluation of upadacitinib 
exposure levels below and above the 15 mg dose, respectively, that have not been evaluated in other 
indications.  The proposed 11 mg and 22 mg doses are expected to provide upadacitinib exposures that 
partially overlap with those achieved with the 15 mg dose, but at the same time provide enough 
separation between the doses to enable adequate characterization of the dose/exposure-response 
relationship.  The 6 mg dose was selected to ensure characterization of the minimally efficacious dose in 
the vitiligo patient population.

dates, and dosage information including dose, route, and frequency on the appropriate electronic case 
report form (eCRF).  Also, medications taken for vitiligo since date of diagnosis (based on subject 
recollection and available medical records) should be entered into the appropriate eCRF inclusive of the 
dates of first and last dose, maximum dosage taken, and route of administration.
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 his/her site if 
he/she has 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.  The AbbVie 
Therapeutic Area Medical Director (TA MD)/Scientific Director may mandate individual subject 
discontinuation from study drug in case of safety concern.
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, as determined by 
the investigator or the AbbVie TA MD.

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 DVT, pulmonary embolus 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.

Subject develops a malignancy, except for localized NMSC or carcinoma in-situ of the cervix.

Subject develops a GI perforation (defined as acute, spontaneous perforation of the GI tract that 
requires inpatient medical care or urgent surgical intervention other than appendicitis or 
mechanical injury).  See also Section 6.2 Toxicity Management.

The subject becomes pregnant or plans to become 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.  Note:  intentional/prospective deviations from 
the protocol are NOT allowed, see Section 5.9 Protocol Deviations.

STUDY M19-051  |  Version 2.0  |  EudraCT 2021-000081-15
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.

Introduction of prohibited medications or dosages when continuation of the study drug would 
place the subject at risk.

Subject is significantly non-compliant with study procedures.

Worsening vitiligo as defined by an increase of 25% or higher in T-VASI from Baseline beginning 
at Week 8.
Additional requirements related to abnormal laboratory values and selected AESIs are located in 
Section 6.2.
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.  The investigator should contact the sponsor 
medical contact before discontinuing a subject from the study for a reason other than "planned per 
protocol," to ensure all acceptable mitigation steps have been explored.
5.6 Follow-Up After Subject Discontinuation
If a subject prematurely discontinues study drug, the procedures outlined for the Premature 
Discontinuation (PD) Visit should be completed as soon as possible, preferably within 2 weeks of study 
drug discontinuation, and preferably prior to initiation of another therapy.  In addition, a 30-day 
Follow-up Visit or phone call should occur to determine the status of any ongoing AEs/SAEs or the 
occurrence of any new AEs/SAEs.
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.
In the event 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 the subject has 
withdrawn and no longer wishes biomarker research to continue, 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.
5.7 Study Drug
Study drug will be taken orally QD, beginning on Day 1 (Baseline), and should be taken at approximately 
the same time each day, with or without food. Subjects will be instructed to return all drug containers 
(even if empty) to the study site personnel at each study visit; study site personnel will document 
compliance.

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.  Subjects who meet eligibility criteria at Baseline 
will be randomized in a 2:2:2:1:1 ratio to one of the five treatment groups:

Group 1:  upadacitinib 22 mg QD (N = 40) (Period 1) → upadaciNnib 22 mg QD (Period 2)

Group 2:  upadacitinib 11 mg QD (N = 40) (Period 1) → upadaciNnib 11mg QD (Period 2)

Group 3:  upadacitinib 6 mg QD (N = 40) (Period 1) → upadacitinib 6 mg QD (Period 2)

Group 4:  placebo (N = 20) (Period 1) → upadaciNnib 22 mg QD (Period 2)

Group 5:  placebo (N = 20) (Period 1) → upadaciNnib 11 mg QD (Period 2)

STUDY M19-051  |  Version 2.0  |  EudraCT 2021-000081-15
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
Randomization will be stratified by the age group (≤ 50 and > 50), Baseline disease severity (T-VASI < 15 
and ≥ 15), and status of active vitiligo (Yes/No) defined as follows:

Active:  Showing new lesions or progression (enlargement) of existing lesions within the last 
6 months and/or presenting clinical subtypes indicative of progressing vitiligo (i.e., confetti-like 
depigmentation, trichrome pattern, or Koebner phenomenon).
At Week 24, subjects who were randomized to placebo at Baseline will be switched to either 22 mg 
(Group 4) or 11 mg (Group 5) upadacitinib in a blinded fashion per pre-specified randomization 
assignments.
All AbbVie personnel with direct oversight of the conduct and management of the trial (with the 
exception of AbbVie Drug Supply Management Team) will remain blinded to each subject's treatment 
until the Week 24 primary analysis for the study, while the investigator, study site personnel, and the 
subject will remain blinded to each subject's treatment throughout the study.  To maintain the blind, the 
upadacitinib tablets and placebo tablets provided for the study will be identical in appearance.  The IRT 
will provide access to unblinded subject treatment information in the case of a 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 the technical support of the IRT vendor via either phone (preferred) or email 
(support@endpointclinical.com).  For country-specific phone numbers, please see the following website:  
http://www.endpointclinical.com/helpdesk/.
In the event that the blind is broken before notification to the AbbVie 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 appropriate eCRF.
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 IEC/IRB, regulatory authorities (as applicable), and AbbVie.
In Japan, the investigator will record all protocol deviations in the appropriate medical records at the 
site.

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 drug component of the product.
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 damage or 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.  Product complaints occurring during the 
study will be followed up to a satisfactory conclusion.
Medical Complaints/Adverse Events and Serious Adverse Events
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, meets 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 an AE, 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 (as appropriate) as an 
SAE within 24 hours of the site being made aware of the SAE (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 (ADL) 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 AEs reported from the time of study drug administration until 30 days or 5 half-lives, whichever is 
longer, after discontinuation of study drug administration will be collected, whether solicited or 
spontaneously reported by the subject.  In addition, study procedure-related serious and nonserious AEs 
will be collected from the time the subject signs the study-specific informed consent.

Product (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 Investigational Medicinal Product (IMP) in 
accordance with global and local requirements.
AEs 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 AESIs will be monitored during each study:

Serious infections

Opportunistic infections (excluding TB and herpes zoster)

Herpes Zoster

Active TB

CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
GI Perforation Adjudication
Two independent, blinded internal adjudicators along with a third potential tie-breaker adjudicator who 
are gastroenterologists or who have other highly relevant clinical experience will be utilized to assess 
potential AEs of acute spontaneous GI perforation.
Adverse Event Severity and Relationship to Study Drug
The investigator will rate the severity of each AE according to the NCI CTCAE version 5.0, which can be 
accessed at:  http://ctep.cancer.gov/protocolDevelopment/electronic_applications.
If no grading criteria are provided for the reported event, then the event should be graded 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 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.

STUDY M19-051  |  Version 2.0  |  EudraCT 2021-000081-15
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
Pregnancy
While not an AE, pregnancy in a study subject must be reported to AbbVie within 1 calendar day 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 visit.
Subjects who become pregnant during the study must be discontinued from study drug treatment 
(Protocol Section 5.5).
The pregnancy outcome of an elective or spontaneous abortion, stillbirth, or congenital anomaly is 
considered an SAE and must be reported to AbbVie within 24 hours of the site becoming aware of the 
event.
6.2 Toxicity Management
The toxicity management of the AEs, including AESIs, consists of safety monitoring (review of AEs on an 
ongoing basis, and periodic/ad hoc review of safety issues by an independent DMC), 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.  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.
GI Perforation:  Subjects presenting with the onset of signs or symptoms of a GI perforation should be 
evaluated promptly for early diagnosis and treatment.  Subjects with acute, spontaneous perforation of 
the GI tract that requires inpatient medical care or urgent surgical intervention (except for appendicitis 
or mechanical injury) must be permanently discontinued from study drug.
Malignancy:  Subjects who develop malignancy other than 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.
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 treating physician.

STUDY M19-051  |  Version 2.0  |  EudraCT 2021-000081-15
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
Thrombosis Events:  Subjects who develop symptoms of thrombosis should be promptly evaluated and 
treated appropriately.  If the diagnosis of DVT, pulmonary embolus, or non-neurologic arterial 
thrombosis is confirmed, the subject must be permanently discontinued from study drug.
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.  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.  Further, repeat testing may be performed at a local 
laboratory if the subject is unable to use the central laboratory.
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 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 
normal reference range or its Baseline value.
ANC

If confirmed < 1000/µL by repeat testing with new sample, interrupt study drug 
dosing until ANC value returns to normal reference range or its Baseline value.

Interrupt study drug if confirmed < 500/μL by repeat testing with new sample.  If 
value returns to normal reference range or its Baseline value, 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.
ALC

If confirmed < 500/µL by repeat testing with new sample, interrupt study drug 
dosing until ALC returns to normal reference range or its Baseline value.
Total WBC count 

If confirmed < 2000/µL by repeat testing with new sample, interrupt study drug 
dosing until WBC count returns to normal reference range or its Baseline value.

Laboratory 
Parameter
Toxicity Management Guideline
AST or ALT

Interrupt study drug if confirmed ALT or AST > 3 × ULN by repeat testing with new 
sample 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.

Interrupt study drug if confirmed ALT or AST > 3 × ULN by repeat testing with new 
sample along with new appearance of fatigue, nausea, vomiting, right upper 
quadrant pain or tenderness, fever, rash, and/or eosinophilia (> 5% increase from 
Baseline). 

Interrupt study drug if confirmed ALT or AST > 5 × ULN by repeat testing with new 
sample for more than 2 weeks.

If ALT or AST > 8 × ULN, interrupt study drug immediately, confirm by repeat testing 
with a new sample, and 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) and a hepatologist consultation should occur 
within 1 week 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 the 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).
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, then interrupt study drug and 
restart study drug once serum creatinine returns to ≤ 1.5 × Baseline value 
and ≤ULN.
For the above serum creatinine elevation scenarios, complete the supplemental renal eCRF.

6.3 Independent Data Monitoring Committee
To ensure subject safety, an external, independent DMC will review unblinded safety data on a cohort 
level, at approximately 4-month intervals throughout the course of the study, and alert AbbVie to 
possible safety concerns related to the conduct of the study.  The DMC will review safety data to 
determine if there are any significant safety concerns that would warrant any study action.  If necessary 
to assess benefit/risk, the DMC will also be given access to selected efficacy data.
The DMC charter will describe the roles and responsibilities of the DMC members, frequency of data 
reviews, and relevant data to be assessed.  Communications from the DMC to the Study Team will not 
contain information that could potentially unblind the team to subject treatment assignments.
7 STATISTICAL METHODS & DETERMINATION OF SAMPLE SIZE
7.1 Statistical and Analytical Plans
The statistical methods provided in this protocol will be focused on primary and secondary analyses.  
Complete and specific details of the statistical analysis will be described in the Statistical Analysis Plan 
(SAP).
The primary analysis will be conducted after all subjects have completed Week 24, data pertaining to 
Period 1 have been cleaned, and a database lock has occurred for the purpose of efficacy and safety 
analysis in Period 1.  The efficacy analysis performed based on this database lock will be the only and 
final analysis for Period 1.
7.2 Definition for Analysis Populations
The ITT Population includes all randomized subjects.  Subjects will be included in the analysis based on 
treatment as randomized.  The ITT Population will be used for all efficacy analyses.
The following populations will be used for the safety analysis:

The Safety Population (Safety) is defined as all subjects who are randomized and received at 
least 1 dose of study drug in the study.

The all upadacitinib treated (ALL_UPA) Population is defined as all subjects who received at least 
1 dose of upadacitinib in the study.  This population will be used to provide a comprehensive 
summary of safety.
7.3 Handling Potential Intercurrent Events for the Primary Endpoint
The primary endpoint (Section 3.2) will be analyzed in the ITT Population and no intercurrent events will 
be considered.  All data collected, regardless of premature discontinuation of study drug, will be used in 
the analysis.

7.4 Statistical Analyses for Efficacy
The efficacy analysis will be based on the ITT Population and all statistical tests will be performed at a 
2-sided significance level of 0.1.  The 95% confidence interval of the treatment effect will be provided.

For continuous variables, comparisons of change and/or percent change from Baseline will be 
made between upadacitinib and placebo based on the Mixed Model Repeated Measures 
(MMRM) adjusting for treatment, visit, treatment-by-visit interaction, and stratification factors 
derived by the actual value (age group [≤50 and > 50], Baseline disease severity [T-VASI < 15 
and ≥15], and status of active vitiligo [Yes/No]) as fixed factors, and Baseline value as a 
covariate.  The MMRM will be the primary approach to handle missing values for continuous 
endpoints.

For categorical variables, comparisons will be made between upadacitinib and placebo using the
Cochran-Mantel-Haenszel (CMH) test, adjusting for the stratification factors derived by the 
actual value:  age group (≤50 and > 50), Baseline disease severity (T-VASI < 15 and ≥ 15), and 
status of active vitiligo (Yes/No).  Non-Responder Imputation incorporating multiple imputation 
(MI) to handle missing data due to COVID-19 (NRI-MI) will be the primary approach to handle 
missing values for categorical endpoints.
Summary and Analysis of the Primary Endpoint
Analysis of the primary endpoint will be conducted on the ITT Population based on the treatment as 
randomized.  Comparison of the primary endpoint will be made between each upadacitinib dose and 
placebo using the MMRM adjusting for treatment, visit, treatment-by-visit interaction, stratification 
factors derived by the actual value, and Baseline value at a 2-sided significance level of 0.1.
MMRM will be the primary approach to handle missing values.  A sensitivity analysis will also be 
performed for the primary efficacy endpoint, using MI to handle missing values.  Analysis details for 
MMRM, MI, and other sensitivity analyses (if applicable) will be provided in the SAP.
Summary and Analysis of Secondary Endpoints
Analysis of secondary efficacy endpoints will be conducted on the ITT Population based on the 
treatment as randomized.  The continuous endpoints will be analyzed using the same method as for the 
primary endpoint.  The categorical endpoints will be analyzed using the CMH test.  The null hypotheses 
for all secondary endpoints will be tested at a 2-sided significance level of 0.1.
Summary and Analysis of Additional Efficacy Endpoints
Additional endpoints, as described in Section 3.4, will also be analyzed.  Analysis details will be provided 
in the SAP.
Subgroup Analysis for Efficacy
To evaluate the consistency of the efficacy across demographic and other Baseline characteristics, 
summaries and analyses will be performed for selected subgroups for the primary efficacy endpoint.  
The subgroups will be defined in SAP.

7.5 Statistical Analyses for Safety
All safety analyses will be performed for the Safety Population and ALL_UPA Population.  Subjects will be 
analyzed based on the treatment actually received.  The number and percentage of subjects 
experiencing AEs will be tabulated using Medical Dictionary for Regulatory Activities system organ class 
and preferred term, as well as by severity and by relationship to the study drug as assessed by the 
investigator.  Summaries (including percentages and events per 100 patient-years) of SAEs, deaths, and 
AEs leading to discontinuation will be provided as well.
For selected laboratory parameters, a listing of all subjects with any laboratory value above Grade 3 of 
Common Toxicity Criteria will be provided.  Mean change from Baseline in laboratory and vital sign 
variables will be summarized.  Additional details for the safety analysis will be provided in the SAP.
7.6 Interim Analysis
No formal interim analysis of efficacy is planned for this study.  Routine safety reviews will be performed 
by an external independent DMC (see details in Section 6.3).
7.7 Overall Type I Error Control
Multiplicity from multiple comparisons will not be adjusted in this Phase 2 study.
7.8 Sample Size Determination
Assuming a Week 24 percent change from Baseline in F-VASI of 0% in the placebo arm, a conservative 
estimate based on a prior study in vitiligo,14 the planned total sample size of 160 subjects (40 subjects in 
each upadacitinib group, 40 subjects total in the placebo groups) will provide more than 90% power to 
detect the treatment difference of 40% reduction (assuming a standard deviation of 54.8%) in at least 
1 upadacitinib group versus placebo using a 2-sided significance level of 0.1 based on the two-sample

CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
8.2 Ethical Conduct of the Study
The study will be conducted in accordance with the protocol, operations manual, International Council 
for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) guidelines, 
applicable regulations, and guidelines governing clinical study conduct and the ethical principles that 
have their origin in the Declaration of Helsinki.  Responsibilities of the investigator are specified in 
Appendix B.
In cases of COVID-19 pandemic situations leading to difficulties in performing protocol-specified 
procedures, AbbVie will engage with study site personnel in efforts to ensure the safety of subjects, 
maintain protocol compliance, and minimize risks to the integrity of the study while trying to best 
manage subject continuity of care.  This may include alternative methods for assessments (e.g., virtual 
site visits), alternative locations for data collection (e.g., use of a local lab instead of a central lab), and 
shipping investigational product and/or supplies direct to subjects to ensure continuity of treatment 
where allowed.  Refer to the operations manual for additional details.  In all cases, these alternative 
measures must be allowed by local regulations and permitted by IRB/IEC.  Investigators should notify 
AbbVie if any urgent safety measures are taken to protect the subjects against any immediate hazard.
8.3 Subject Confidentiality
To protect subjects' confidentiality, all subjects and their associated samples will be assigned numerical 
study identifiers or "codes."  No identifiable information will be provided to AbbVie.
During the COVID-19 pandemic, remote monitoring of data may be employed if allowed by the local 
regulatory authority, IRB/IEC, and the study site.
9 SOURCE DOCUMENTS AND CASE REPORT FORM 
COMPLETION
The investigator is responsible for ensuring the accuracy, completeness, legibility, and timeliness of the 
data reported.  All source documents should be attributable, legible, contemporaneous, original, 
accurate, and complete to ensure accurate interpretation of data.  Clinical site monitoring is conducted 
to ensure that the rights and well-being of human subjects are protected, that the reported trial data 
are accurate, complete, and verifiable, and that the conduct of the trial is in compliance with the 
currently approved protocol, ICH Good Clinical Practice (GCP), and applicable local regulatory 
requirement(s).  During the COVID-19 pandemic, remote data review/verification may be employed if 
allowed by the local regulatory authority, IRB/IEC, and the study site.

APPENDIX E. PROTOCOL SUMMARY OF CHANGES
Previous Protocol Versions
Protocol
Date
Version 1.0
15 March 2021
The purpose of this version is to address the following changes in addition to minor clerical corrections
for consistency throughout:
Protocol

Update Title Page to change sponsor/emergency medical contact from 
 MD, MS, 
DVM, FAAD to 
MD, PhD, and to update contact information accordingly.
Rationale:  To update due to personnel change.

Update Synopsis and Section 2.1 to add "in some countries" to clarify the approval status of 
upadacitinib for the treatment of RA, PsA, and AS.
Rationale:  To align with indication approvals outlined in the investigator brochure.  According to 
the current IB, upadacitinib is approved for RA and is being evaluated for other indications.

Update Synopsis and Section 5.1 eligibility criterion #17 to indicate that subjects must not have 
been previously treated with any permanent skin bleaching agents to treat vitiligo.  
Rationale:  To clarify that previous treatment with permanent skin bleaching agents to treat 
vitiligo is prohibited. 

Update Section 3.8 to add wording for site and subject participation in the Digital Imaging 
Research.
Rationale:  To clarify the approximate number of sites that will be selected and that subjects at 
participating sites will be required to participate after digital imaging platform is available for 
implementation at the site.

Update Section 5.3 to revise the dose for systemic corticosteroids from 1 mg/kg to 1 mg/kg/day.
Rationale:  To provide the correction needed regarding the maximum dose of systemic 
corticosteroids allowed.

Update Section 5.3 to change the wording regarding natural daily light exposure from 
"encouraged" to "allowed."
Rationale:  To provide clarification.  

Update Section 5.3 to add language prohibiting use throughout the study of any drugs 
considered to be strong CYP3A inhibitors or inducers, or herbal supplements or traditional 
medicines with unknown effects on CYP3A.
Rationale:  To provide additional language as topical and supplemental treatments may 
interfere with upadacitinib metabolism and exposure and may also impact efficacy and safety of 
upadacitinib treatment.

STUDY M19-051  |  Version 2.0  |  EudraCT 2021-000081-15
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.

Update to Targeted Biologic Therapies in Section 5.3 to include the U.S. marketed product name
and to update to the registered trademark for EU SKYRIZI.
Rationale:  To provide clarification.

Update Section 5.5 to add the following language in the event that an eligibility criteria violation 
was noted after the subject started study drug and continuation of study drug would place the 
subject at risk:  "Note: indicate that intentional/prospective deviations from the protocol are not 
permitted."
Rationale:  To provide clarification in response to a request from Health Canada.  

Update Section 5.5 to condense the wording regarding subject non-compliance with study 
procedures.
Rationale:  To simplify the wording as significant non-compliance with study procedures would 
be sufficient cause to consider discontinuation for a clinical trial, regardless of the perceived risk 
to the subject.  Also, significant non-compliance has the potential to have a negative impact on 
the scientific integrity of the study.  

Update Section 5.5 to add "beginning at Week 8" to the discontinuation criterion regarding 
worsening vitiligo as defined by an increase of 25% or higher in T-VASI from Baseline.
Rationale:  To clarify that subjects with 25% increase in T-VASI will not be discontinued until 
Week 8 to allow sufficient time for upadacitinib to show some improvement, thus minimizing 
early premature discontinuation.

Update Section 7.4 to clarify that categorical stratification factors will be adjusted in the models.
Rationale: to clarify that categorical stratification factors are adjusted in the models instead of 
the continuous values of the variables.

Update Appendix A to add abbreviations.
Rationale:  To keep abbreviations list current.

Update Appendix C to revise List of Protocol Signatories.
Rationale:  To update protocol signatories to reflect current personnel.  

Update Appendix D to add respiratory rate and body temperature to vital signs.
Rationale:  To provide consistency for vital signs in Operations Manual Section 3.14 where vital 
signs are defined as "systolic and diastolic blood pressure in sitting position, heart rate, 
respiratory rate, and body temperature," and in Appendix D, Activity Schedule. 
Operations Manual

Update Section 1 and Section 4.3 to change sponsor/emergency medical contact from 
 
 MD, MS, DVM, FAAD to 
 MD, PhD, and to update contact 
information accordingly.
Rationale:  To update due to personnel change.

Update Section 2.1 Baseline/Day 1 to add a footnote indicating that study drug dispensed at 
Baseline contains 35 tablets; therefore, study drug will not be dispensed from IRT at Week 2.
Page 55 of 125
 


  
STUDY M19-051  |  Version 2.0  |  EudraCT 2021-000081-15
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
Rationale:  To provide clarification that no study drug dispensation from the IRT system will 
occur at the Week 2 visit.

Update Section 2.1 Week 2/Day 15 to add a footnote that study drug dispensation from IRT at 
Baseline will be reviewed for compliance and returned to subject at this visit. IRT dispensation 
at this visit is not available.
Rationale:  To clarify that no study drug dispensation from the IRT system will occur at the 
Week 2 visit.

Update Section 2.1 Week 12/Day 85, Week 24/Day 169, Week 36/Day 253, Week 44/Day 309, 
and Premature Discontinuation Visit to add the following footnote regarding HBV post-Baseline 
tests for subjects from Japan only: HBV DNA PCR testing approximately every 12 weeks is not 
necessary when the subject has a history of HBV vaccination and HBs Ab+ and HBc Ab–.  If 
necessary, HBV DNA PCR may be tested at unscheduled visits.
Rationale: To clarify when additional testing is required.

Update Section 3.3 to add language that additional temporary verbal consent may be obtained 
in accordance with local regulations, followed by an appropriately signed and dated informed 
consent form obtained from the subject afterwards, as soon as possible.
Rationale:  To provide updated guidance on informed consent from subjects due to protocol 
modifications that may become necessary during the COVID-19 pandemic.

Update Section 3.7 to clarify the description of the VNS and VitiQoL.
Rationale:  To provide clarification.

Update Section 3.7 to correct the response option ranges from 0 = no depigmentation to 
4 = very extensive pigmentation.
Rationale:  To provide correction for T-PaGVA and F-PaGVA scale response options.

Update Section 3.8 to add language regarding how the VES will initially be collected and how the 
final score will be calculated before upload into EDC by the site.
Rationale:  To clarify the steps necessary to collect the VES based on the way it was initially 
validated.

Update Section 3.9 to replace the level of bother response option of "not applicable" to "area 
not affected by vitiligo."
Rationale:  To clarify how some of the ICVA data is collected into EDC.

Update Section 3.11 to state that PK samples should be collected at 0.5 to 4 hours post-dosing
at Baseline and Week 4.  At Weeks 8, 12, and 24, subjects should take the study drug dose at the 
clinic within 30 minutes after collecting the PK blood sample.
Rationale:  To add PK collection timepoint for Baseline and a 30-minute window for taking study 
drug dose after PK sample collection at Weeks 8, 12, and 24.

Update Section 3.11 to indicate that data and accurate time of dose administration will be 
recorded in the eCRF for doses administered at the clinic during a study visit.
Rationale:  To provide additional clarification regarding data and accurate time capture of study 
drug dose administration.

STUDY M19-051  |  Version 2.0  |  EudraCT 2021-000081-15
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.

Update Section 3.13 to indicate that body weight will be measured at scheduled visits as 
specified in Section 2.1 and in Appendix D, Activity Schedule.
Rationale:  To clarify weight collection timepoints.

Update Section 3.14 to change "pulse rate" to "heart rate."
Rationale:  To provide consistency with wording in Section 3.14 and Appendix D, Activity 
Schedule.

Update Section 3.18 to remove the following sentence:  "AbbVie will not receive results from 
the testing and will not be made aware of any positive result."
Rationale:  Although AbbVie does not require receiving HIV test results, AbbVie CRAs are 
required to verify all study eligibility criteria, including the lack of confirmed positive anti-HIV 
antibody test, therefore the statement was removed to accurately reflect the current AbbVie 
monitoring practice.

Update Section 3.19 to indicate that the first dose of study drug will be administered after all 
other Baseline (Day 1) procedures are completed, with the exception of the PK blood draw.
Rationale:  To clarify that Baseline PK draw should be performed post-dose.

Update Section 3.19 to indicate that subjects should be instructed to administer their dose at 
the site during the study visit and not at home prior to the visit; however, the subject should 
follow the regular dosing schedule if study drug administration is normally after the time of the 
scheduled study visit.
Rationale: To clarify that the dose on the study day visit should be administered at the site to 
allow appropriate collection of PK samples in relation to the dosing time.

Update Section 3.20 to add "unless performed at a local laboratory" to indicate when a lab re-
test will be considered an Unscheduled Visit.
Rationale:  To provide further clarification regarding on-study unscheduled visits.

Update Section 4.1 to add language regarding toxicity management for abnormal labs and that 
additional supplemental eCRFs (hepatic and renal) may need to be completed.
Rationale:  To provide clarification regarding additional supplemental eCRFs required for toxicity 
management for abnormal labs, as described in Protocol Section 6.2.

Update Section 7.1 to clarify the question in the PaGIC-V Example to "Since the start of the 
treatment you've received in this study, your vitiligo is…".
Rationale:  To clarify the question since this is a pill and therefore "your vitiligo in areas treated 
with the study" would not apply.

Update Section 7.1 to provide numerical score rate response options of 0 – 4 for the T-PaGVA 
and F-PaGVA scales.
Rationale:  To correct the T-PaGVA and F-PaGVA scales as score rate (0 – 4) was missing.

Update Section 7.2 to update the Vitiligo History Form Example wording from "any other family 
member" to "any other biological family member."
Rationale:  To provide a necessary correction on the paper version of the form.

Introduction
This Statistical Analysis Plan (SAP) describes the statistical analyses for upadacitinib 
Study M19-051 'A Multicenter, Randomized, Double-Blind, Placebo-Controlled Dose-
Ranging Study to Evaluate the Safety and Efficacy of Upadacitinib in Subjects with Non-
Segmental Vitiligo.'
Study M19-051 examines the efficacy and safety of upadacitinib for the treatment of adult 
subjects with non-segmental vitiligo (NSV).
The analyses of pharmacokinetic endpoints and biomarkers 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 Design and Objectives
2.1
Objectives, Hypotheses and Estimands
The primary objective of this study is to evaluate the safety and efficacy of upadacitinib 
for the treatment of adult subjects with NSV.  The primary efficacy objective is based on 
the percent change from Baseline in Facial Vitiligo Area Scoring Index (F-VASI) at Week 
24 with upadacitinib treatment compared to placebo in the Intent-to-Treat (ITT) 
Population, which consists of all randomized subjects.
The hypothesis corresponding to the primary endpoint is:
Percent change from Baseline in F-VASI with upadacitinib is greater than that with 
placebo at Week 24.
The estimand corresponding to the primary endpoint is defined as:
 


Upadacitinib
M19-051 – Statistical Analysis Plan
Version 2.0 – 27 December 2022

Difference in the percent change from Baseline in F-VASI at Week 24, regardless of 
treatment discontinuation, between each of the upadacitinib dose groups compared with 
placebo in the adult subjects with NSV.
2.2
Study Design Overview
This is a Phase 2, multicenter, randomized, double-blinded, parallel-group, placebo-
controlled dose-ranging study that will evaluate the safety and efficacy of upadacitinib in 
adult subjects ≥ 18 to 65 years of age with NSV.  The study is comprised of a 35-day 
Screening Period, a 24-week double-blind treatment period (Period 1), a 28-week blinded 
long-term extension (Period 2), and a 30-day Follow-up Period.
Subjects who meet eligibility criteria at Baseline will be randomized in a 2:2:2:1:1 ratio to 
one of five treatment groups:
●
Group 1: upadacitinib 22 mg once daily (QD) (N = 40) (Period 1) → 
upadacitinib 22 mg QD (Period 2)
●
Group 2: upadacitinib 11 mg QD (N = 40) (Period 1) → upadacitinib 11mg 
QD (Period 2)
●
Group 3: upadacitinib 6 mg QD (N = 40) (Period 1) → upadacitinib 6 mg QD 
(Period 2)
●
Group 4: placebo (N = 20) (Period 1) → upadacitinib 22 mg QD (Period 2)
●
Group 5: placebo (N = 20) (Period 1) → upadacitinib 11 mg QD (Period 2)
At Week 24, subjects who were randomized to placebo at Baseline will be switched to 
either upadacitinib 22 mg (Group 4) or upadacitinib 11 mg (Group 5) in a blinded fashion 
per pre-specified randomization assignments.
The AbbVie study team will be unblinded to perform the Week 24 primary analysis.  The 
unblinding will take place after all subjects have completed the Week 24 visit or have 
prematurely discontinued prior to Week 24.  Sites and subjects will remain blinded 
throughout the study.

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.
Subjects who meet eligibility criteria at Baseline will be randomized in a 2:2:2:1:1 ratio to 
one of the five treatment groups:
●
Group 1: upadacitinib 22 mg QD (N = 40) (Period 1) →upadacitinib 22 mg 
QD (Period 2)
●
Group 2: upadacitinib 11 mg QD (N = 40) (Period 1) →upadacitinib 11mg 
QD (Period 2)

●
Group 3: upadacitinib 6 mg QD (N = 40) (Period 1) →upadacitinib 6 mg QD 
(Period 2)
●
Group 4: placebo (N = 20) (Period 1) →upadacitinib 22 mg QD (Period 2)
●
Group 5: placebo (N = 20) (Period 1) →upadacitinib 11 mg QD (Period 2)
Randomization will be stratified by the age group (≤ 50 and > 50), Baseline disease 
severity (T-VASI < 15 and ≥ 15), and status of active vitiligo (Yes/No) defined as 
follows:
●
Active: Showing new lesions or progression (enlargement) of existing lesions 
within the last 6 months and/or presenting clinical subtypes indicative of 
progressing vitiligo (i.e., confetti-like depigmentation, trichrome pattern, or 
Koebner phenomenon).
At Week 24, subjects who were randomized to placebo at Baseline will be switched to 
either 22 mg (Group 4) or 11 mg (Group 5) upadacitinib in a blinded fashion per pre-
specified randomization assignments.
2.4
Sample Size Determination
Assuming a Week 24 percent change from Baseline in F-VASI of 0% in the placebo arm, 
a conservative estimate based on a prior study in vitiligo,1 the planned total sample size of 
160 subjects (40 subjects in each upadacitinib group, 40 subjects in total in the placebo 
groups) will provide more than 90% power to detect the treatment difference of 40% 
reduction (assuming a standard deviation of 54.8%) in at least 1 upadacitinib group versus 
placebo using a 2-sided significance level of 0.1 based on the two-sample t-test.

Prior and concomitant medications will be summarized by generic name in the Safety 
population. A prior medication is defined as any medication taken prior to the date of the 
first dose of study drug and will be summarized in Period 1.  For Period 1 and 2, a 
concomitant medication in each period is defined as any medication that started prior to 
the date of the first dose of study drug in each period and continued to be taken after the 
first dose of study drug in each period or any medication that started on or after the date of 
the first dose of study drug in each period, but not after the date of the last dose +1 of 
study drug in each period.  The number and percentage of subjects taking medications will 
be summarized by generic drug name based on the World Health Organization (WHO) 
Drug Dictionary for both prior and concomitant medications.
In addition, subjects' prior exposure to topical treatment (topical corticosteroid [TCS], 
topical calcineurin inhibitor [TCI]), systemic corticosteroids, phototherapy, procedure, 
and other will be summarized for each treatment group.
8.0
Handling of Potential Intercurrent Events for the 
Primary Endpoint
The primary efficacy endpoint of percent change in F-VASI at Week 24 (defined in 
Section 3.1) will be analyzed based on the ITT_1 Populations.  For treatment policy 
strategy, the occurrence of the intercurrent event (treatment discontinuation) is considered 
as irrelevant in defining the treatment effect of interest.  Under this strategy, the value for 
the variable of interest is used regardless of whether or not the intercurrent event occurs.

Efficacy Analyses
9.1
General Considerations
All efficacy analyses will be conducted in the ITT Population in each period (ITT_1 and 
ITT_2).  All tests will be 2-sided at an alpha level of 0.1.
The Primary Analysis will be performed after all ongoing subjects have completed 
Week 24 or have prematurely discontinued prior to Week 24, data pertaining to Period 1 
has been cleaned, and the database has been locked.  This will be the only and final 
analysis for the efficacy endpoints in Period 1.
For analysis in Period 1, continuous endpoints and categorical endpoints will be analyzed 
using Mixed-Effect Model Repeat Measurement (MMRM) and Cochran-Mantel-Haenszel 
(CMH), respectively.
The analysis models and imputation methods for categorical and continuous endpoints in 
Period 1 and Period 2 are summarized in the following table:

To evaluate long-term efficacy, all endpoints (categorical and continuous) will be 
summarized descriptively at each visit by treatment groups overall and by stratification 
factors.
Analysis of Continuous Variables
In Period 1, the Baseline means and visit means will be presented for each treatment 
group who have both Baseline and post-baseline visit values.  Change (and/or percent 
change) from Baseline in the treatment groups will be compared using MMRM as 
described in Table 1.  Point estimates, SE, and 95% confidence interval (CI) of LS mean 
change (and/or percent change) from Baseline within treatment groups, along with p-
values between each upadacitinib treatment group and placebo will be provided.  MMRM 
will be the primary approach to handle missing data for continuous endpoints 
(Section 9.2) in Period 1.  In addition, the primary efficacy endpoint will be analyzed 
using MI defined in Section 9.2 as the sensitivity analysis.
For long-term efficacy, the raw value at Baseline and each visit will be summarized using 
mean for each of the 5 treatment groups as observed.  For change (and/or percent change) 
from Baseline, LS mean, SE, and 95% CIs generated by ANCOVA by visit as described 
in Table 1.  Descriptive summary statistics including median, Q1, Q3, minimum and 
maximum of change (and/or percent change) from Baseline will also be provided.
Analysis of Categorical Variables
In Period 1, frequencies and percentages will be provided along with 95% CIs.  Point 
estimates, 95% CIs and p-values from the CMH test for the difference in proportions 
between each upadacitinib group and placebo will be provided.  Breslow-Day test will be 
performed to test the homogeneity between strata.
Non-Responder Imputation while incorporating Multiple Imputation (MI), NRI-MI, will 
be the primary approach to handle missing data for categorical endpoints in Period 1 
(Section 9.2 and Appendix E).

●
If there are missing data due to COVID-19 or any other missing data that can 
be reasonably assumed to be Missing at Random, a total of 30 datasets will be 
generated by PROC MI, and subjects will be characterized as responders or 
non-responders based on MI imputed values.
○
If not all the imputed datasets are identical, analysis will be performed as 
described in Appendix E.
○
If all the 30 imputed datasets are identical, all statistical inferences will be 
calculated using the first imputed dataset: 1) The corresponding 95% CIs 
will be constructed based on normal approximation to the binomial 
distribution.  2) Adjusted differences, 95% CIs and p-values for the 
comparisons between each upadacitinib group and placebo will be 
calculated based on CMH test adjusting for stratification factors.
●
If there are no missing data due to COVID-19 or any other missing data that 
can be reasonably assumed to be Missing at Random, the NRI-MI method will 
be the same as traditional NRI method.  All statistical inferences will be 
calculated using the NRI imputed datasets.
For long-term efficacy, descriptive summary statistics including frequencies and 
percentages for categorical endpoints, along with 95% CIs based on normal 
approximation, will be provided based on as observed data.
Unless otherwise specified, any subject who is randomized based on a wrong stratum will 
be analyzed according to the actual stratum the subject belongs to.
"Baseline" refers to the last non-missing observation before the first administration of 
study drug or randomization if no study drug is given.
9.2
Handling of Missing Data
In Period 1, missing data will be imputed using the following methods for the efficacy 
analyses:
●
Mixed-Effect Model Repeat Measurement (MMRM):  The repeated measures 
analysis will be conducted using a mixed model including observed 
 


Upadacitinib
M19-051 – Statistical Analysis Plan
Version 2.0 – 27 December 2022
20
measurements at all visits.  The mixed model includes treatment, visit and 
treatment-by-visit interaction, and stratification factors (age group [≤ 50 and 
> 50], Baseline disease severity [T-VASI < 15 and ≥ 15], and status of active 
vitiligo [Yes/No]) derived from actual values as fixed factors, and Baseline 
value as a covariate.  An unstructured variance covariance matrix will be used.  
If the model cannot converge, an appropriate covariance structure matrix 
(e.g., autoregressive (1) or compound symmetry) will be used, and/or the 
stratification factor of age will not be included in the model.  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 in Period 1.
●
Non-Responder Imputation while incorporating Multiple Imputation (MI) to 
handle missing data due to COVID-19 or any other missing data that can be 
reasonably assumed to be Missing at Random (NRI-MI): The NRI-MI will 
categorize any subject who does not have an evaluation during a pre-specified 
visit window (either due to missing assessment or due to early withdrawal 
from the study) as a non-responder for the visit.  The only exceptions are:  
1) when the subject is a responder both before and after the visit window in 
Period 1, the subject will be categorized as a responder for the visit.  
2) missing data due to COVID-19 infection or logistical restriction or any 
other missing data that can be reasonably assumed to be Missing at Random 
will be handled by MI.  The NRI-MI will be the primary approach in the 
analyses of categorical variables in Period 1.  Random seeds are provided in 
Appendix D and more details are provided in Appendix E.  NRI-MI is the 
primary approach to handle missing data for categorical endpoints in Period 1.
●
Multiple Imputation (MI):  The MI approach will be used as a sensitivity 
analysis for the primary efficacy endpoint.  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 variables to be included in the imputation model are:  treatment 
group, stratification factors (age group [≤ 50 and > 50], Baseline disease 
severity [T-VASI < 15 and ≥ 15], and status of active vitiligo [Yes/No]) 
derived from actual values, Baseline, and measurements at each visit up to the 
end of the Period 1.  The random seed for MCMC and the random seed for 
 


Upadacitinib
M19-051 – Statistical Analysis Plan
Version 2.0 – 27 December 2022
21
PROC MI are specified in Appendix D.  The imputed post-baseline 
measurements will be rounded to the same precision as the observed data.  The 
imputed endpoint will be analyzed using each of the 30 datasets using 
ANCOVA for the primary endpoint.  SAS PROC MIANALYZE will be used 
to generate the final inferences of the difference between upadacitinib group 
and placebo.
In Period 2, all values collected in the study will be used to summarize the long-term
efficacy as observed (AO) in Period 2:
●
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.
9.3
Primary Efficacy Endpoint and Analyses
9.3.1
Primary Efficacy Endpoint
The primary endpoint is the percent change from Baseline in F-VASI at Week 24.
The corresponding statistical null hypothesis to the primary endpoint is that there is no 
difference between any upadacitinib treatment group and placebo, in the LS mean of 
percent change from Baseline in F-VASI at Week 24.
9.3.2
Main Analysis of Primary Efficacy Endpoint
The primary analysis of the primary efficacy endpoint will be conducted in the ITT_1 
Population based on treatment as randomized.  The primary analysis is the comparison 
between upadacitinib and placebo at Week 24 using MMRM, and the corresponding 
analyses are specified in Section 9.1.
The attributes of the estimands corresponding to the primary efficacy endpoint are 
summarized in Table 2.

The second analysis of the primary efficacy endpoint is to test a pre-specified set of dose-
response models among upadacitinib dose groups and placebo group at Week 24 using 
Multiple Comparison Procedure – Modeling (MCP-Mod).
The dose-response relationship among upadacitinib dose groups and the placebo will be 
characterized for the primary endpoint using MCP-Mod2.  The percent change from 
Baseline and standard deviations in each upadacitinib dose groups and placebo based on 
the primary analysis will be used, and ADDPLAN DF software Version 4.0 will be used 
to perform the MCP-Mod analyses.
A set of 6 pre-specified standardized candidate dose-response models, as described in 
Table 3, will be utilized to examine the dose-response relationship.  For the primary 
endpoint, a statistically significant dose-response relationship will be declared if at least 
one model is identified by the MCP-Mod method to be statistically significant at 2-sided 
significance level of 0.1.  Instead of choosing an optimal dose-response relationship 
model, a weighted average of the minimum effective dose (MED) (i.e., the recommended 
MED) across all significant models will be calculated for the MED selection.

1.
The MED of each statistically significant model will be determined based on the 
pre-specified clinical meaningful target of a 40% target difference from placebo.
2.
The weighted average of MED across all significant models will be calculated, 
with the weight  of model  calculated using Akaike information criterion (AIC) 
as:

The rationale for using a weighted average of MED is because selecting a single model as 
the 'best' representation of observed data and subsequently using it to estimate the MED 
does not account for uncertainty in model selection.  The uncertainty in model selection 
can be accounted for by averaging estimates of MED over all significant models.

mg will achieve 95% of the maximum efficacy effect.  For exponential model, the initial values for the 
parameter is solely based on the assumption that upadacitinib 22 mg will achieve 95% of the maximum 
efficacy effect.
The fitted dose-response curves will be presented graphically for all statistically 
significant models along with confidence bands. 
9.3.3
Sensitivity Analyses of the Primary Efficacy Endpoint
A sensitivity analysis using MI to handle missing data for the primary efficacy endpoint 
will be performed, as described in Section 9.2.

Secondary Efficacy Analyses
9.4.1
Main Analyses of Secondary Efficacy Endpoints
Secondary efficacy endpoints in Period 1 will be analyzed by comparing each 
upadacitinib treatment group with placebo.
Comparisons of the categorical endpoints will be made between each upadacitinib 
treatment group and placebo using the CMH test, adjusting for the stratification factors 
derived from actual values under a two-sided significance level of 0.1 for each 
upadacitinib group, and the corresponding analyses are specified in Section 9.1.
The continuous endpoints will be analyzed using MMRM at a two-sided significance 
level of 0.1 for each upadacitinib group, and the corresponding analyses are specified in 
Section 9.1 and Section 9.2.
9.5
Additional Efficacy Analyses
In Period 1, unless otherwise specified, additional efficacy endpoints will be compared 
between the each upadacitinib treatment group and placebo.  The categorical endpoints 
and continuous endpoints will be analyzed by CMH and MMRM, respectively, and the 
analyses are specified in Section 9.1 and Section 9.2.  Proportion of subjects selecting 
each of the 16 VitiQoL questions will be summarized for each of the 16 questions by 
response categories at each visit as observed.
In Period 2, the categorical endpoints will be summarized by treatment groups as 
observed, and the continuous endpoints will be analyzed as observed using ANCOVA as 
described in Table 1.  The analyses are specified in Section 9.1 and Section 9.2.
In Addition, at the time of the Primary Analysis, additional long-term analysis up to 
Week 52 will be provided for the below variables among all subjects who may potentially 
reach to Week 52 by the data cutoff using NRI-MI (categorical variables) or MMRM

10.2.1
Treatment-Emergent Adverse Events
For Period 1, treatment-emergent adverse events (TEAEs) are defined as any adverse 
events that begin or worsen in severity after initiation of study drug through 30 days 
following the last dose of study drug in Period 1 or prior to first dose in Period 2, 
whichever is earlier.  For Period 2, TEAEs are defined as any adverse events that begin or 
worsen in severity after initiation of study drug in Period 2 through 30 days following the 
last dose of study drug in Period 2.  A TEAE during the administration of upadacitinib 
(i.e., among the ALL_UPA Population) is defined as any AE with an onset date on or 
after the first dose of upadacitinib and within 30 days after the last dose of upadacitinib.  
Events where the onset date is the same as the study drug start date are assumed to be 
treatment emergent.
All TEAEs will be summarized overall, as well as by primary MedDRA SOC and PT.  
The SOCs will be presented in alphabetical order, and the PTs will be presented in 
alphabetical order within each SOC. For the Safety_1 and ALL_UPA Populations, the 
number and percentage of subjects experiencing TEAEs and the number of events per 
100 patient-years of exposure will be summarized.

The overview of number of TEAEs/deaths per 100 patient-years of exposure will also be 
provided for the above categories for the Safety_1 and ALL_UPA Populations.
TEAEs per 100 patient-years of exposure are defined as the number of TEAEs divided by 
the total exposure in 100 patient-years. The exposure-adjusted TEAE rate per 100 patient-
years is calculated as:
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) +1 day (not to exceed the start of subsequent period) of all subjects 
normalized by 365.25, and rounded to 1 decimal place.
10.2.3

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; by 
relationship to COVID-19 and SOC and PT; by ≥5% subjects in any treatment group by 
SOC and PT.  The number and percentage of subjects experiencing TEAEs will be 
provided for these summaries in the Safety_1 and ALL_UPA Populations.  Number of 
TEAEs per 100 patient-years of exposure will be summarized by SOC and PT for the 
Safety 1 and All_UPA Populations.  Specific adverse events will be counted once for each 
subject for calculating percentages, unless stated otherwise.  In addition, if the same 
adverse event occurs multiple times within a subject, the highest toxicity and level of 
relationship to investigational product will be reported.

Non-Responder Imputation Incorporating Multiple Imputation to 
Handle Missing Data Due to COVID-19 Pandemic or Any Other 
Missing Data that Can Be Reasonably Assumed to Be Missing at 
Random for Dichotomized Outcome Variables
1.0
Overview
1.1
Background and Justification for Missing at Random (MAR) 
Assumption
The COVID-19 pandemic is interfering with the conduct of many ongoing trials, with 
potential impacts on treatment duration and the collection, analysis and the interpretation 
of clinical trial data.  Some protocol-specified visits in the clinical trials may be impacted 
due to COVID-19 infection or logistical restrictions during the pandemic.  For example, 
some scheduled visits may be missed due to self-quarantine or local government 
restrictions on travel; some visits may also be delayed or canceled due to healthcare 
resource constraints during the pandemic.  Impacted visits due to COVID-19 will be 
recorded in the database.  The probability of having missed visits and missing data due to 
COVID-19 infection or logistical restrictions related to the COVID-19 pandemic can be 
reasonably assumed to be unrelated to the unobserved values.  Therefore, for the purpose 
of statistical analysis, it is reasonable to assume that these missing data are missing at 
random (MAR) and the statistical models that require MAR assumption are appropriate.  
In some cases, sensitivity analyses may be performed to assess the impact of missing data 
and the robustness of the conclusion.
1.2
FDA Guidance
FDA provided two guidance documents1,2 in March 2020 and June 2020 on the efficacy 
collection and possible changes in the statistical analysis plan:
●
"With respect to efficacy assessments, FDA recommends consultation with the 
appropriate review division regarding protocol modifications for the collection 
of efficacy endpoints, such as use of virtual assessments, delays in 
assessments, and alternative collection of research-specific specimens, if 
feasible.  For individual instances where efficacy endpoints are not collected, 
 


Upadacitinib
M19-051 – Statistical Analysis Plan
Version 2.0 – 27 December 2022
43
the reasons for failing to obtain the efficacy assessment should be documented 
(e.g., identifying the specific limitation imposed by COVID-19 leading to the 
inability to perform the protocol-specified assessment)."
●
"If changes in the protocol will lead to amending data management and/or 
statistical analysis plans, the sponsor should consider doing so in consultation 
with the applicable FDA review division.  Prior to locking the database, 
sponsors should address in the statistical analysis plan how protocol deviations 
related to COVID-19 will be handled for the prespecified analyses."
1.3
EMA Guidance
EMA provided guidance3 in March 2020:
●
"At this point in time it is not possible to give general applicable advice on 
how the different aspects related to the pandemic should be handled, as 
implications on clinical trials are expected to be manifold.  Impact on the data 
collection, analysis and interpretation of results for each trial will need a 
thorough case-by-case assessment."
●
"As a general principle, there are strong scientific reasons to conduct trials as 
planned and implement changes only when there is a convincing scientific
reason that it improves interpretability of results."
1.4
Missing Data Handling for Missing Due to COVID-19 for 
Dichotomized Variables
In this document, a missing data handling method is proposed to handle missing data due 
to COVID-19 infection or logistical restrictions related to the COVID-19 pandemic under 
the general MAR framework.  In particular, we explain using multiple imputation (MI) to 
handle missing data due to COVID-19 or any other missing data that can be reasonably 
assumed to be Missing at Random in dichotomized variables in conjunction with non-
responder imputation (NRI) for missing data due to other reasons.

2.0
Non-responder Imputation Incorporating Multiple 
Imputation (NRI-MI)
2.1
Overall Description of the Method
For a dichotomized outcome variable with missing data, the NRI-MI will categorize any 
subject who does not have evaluation during a pre-specified visit window as a non-
responder for the visit, with two exceptions:
●
If the subject is a responder both before and after the pre-specified visit 
window in Period 1, the subject will be categorized as a responder for the visit.
●
If the reason for missing (e.g., missed visits, incomplete visit, out-of-schedule 
visits, or discontinuations of study drug) is due to COVID-19 or any other 
missing data that can be reasonably assumed to be Missing at Random, the 
information will be captured in the database and the subject's response status 
will be imputed using multiple imputation.
In addition, subjects whose change/percent change from Baseline cannot be calculated 
because of a missing Baseline will be considered as a non-responder at all post-baseline 
visits unless the post-baseline value is zero.
Non-responder imputation incorporating multiple imputation (NRI-MI) for missing due to 
COVID-19 or any other missing data that can be reasonably assumed to be Missing at 
Random will be implemented as follows.
2.2
Multiple Imputation (MI) and MAR Assumption
When a dichotomized variable is derived from a continuous scale, for example, F-VASI 
75 (at least a 75% reduction in F-VASI relative to Baseline), the multiple imputation will 
be applied to the original scale, F-VASI (ranges from 0 – 100) assuming multivariate 
normal distribution.  Then the dichotomized variable will be derived from the imputed 
value.
 


Upadacitinib
M19-051 – Statistical Analysis Plan
Version 2.0 – 27 December 2022
45
The MI procedure assumes that the data are missing at random (MAR).  That is, for an 
outcome variable Y, the probability that an observation is missing depends only on the 
observed values of other variables, not on the unobserved values of the outcome variable 
Y.  Statistical inference from the MI procedure is valid under the MAR assumption.
2.3
Imputation Algorithm 
It is reasonable to assume the missing values of the longitudinal data for an outcome 
variable (e.g., F-VASI, the original scale of F-VASI 75, at each post-baseline visit) 
follows a monotone missing pattern.  In practice, the missing data of the outcome variable 
might have an arbitrary (non-monotone) missing data pattern.  An extra step may be 
added accordingly, to augment data into a monotone missing pattern.
For the outcome variable (e.g., F-VASI at each visit), K 'complete' datasets can be 
generated in two steps:  augmentation step and imputation step.  K, the number of 
repetitions, is determined below.
Augmentation Step
For datasets with non-monotone missing data pattern, the augmentation step will 
first impute enough values to augment the data into a monotonic missing pattern:
Markov Chain Monte Carlo (MCMC) will be applied to augment the data using PROC MI 
with the MCMC IMPUTE=monotone statement, assuming a multivariate normal 
distribution.  The augmented data will be used in the subsequent imputation step to 
generate 'complete' datasets.  Covariates included in the model are treatment, stratification 
factors (the age group [≤ 50 and > 50], Baseline disease severity [T-VASI < 15 and ≥ 15], 
and status of active vitiligo [Yes/No]), Baseline, and all post-baseline visits of the 
outcome variable according to the pre-specified order.  For T-VASI related endpoints, 
Baseline disease severity (T-VASI < 15 and ≥ 15) will not be included in the model.  Of 
note, categorical variables are included using the form of dummy variables.
 


Upadacitinib
M19-051 – Statistical Analysis Plan
Version 2.0 – 27 December 2022
46
Repeat the imputation process K=30 times using the procedure described above to form 
K=30 monotone missing datasets, where K is determined as described in "Repetition of 
Imputations (K)."
Imputation Step
For missing data with monotone missing patterns, the choice of multiple imputation using 
a parametric regression model that assumes multivariate normality is appropriate.
The imputation step is described below:
●
The imputation model for the missing data is a regression model, which 
controls for treatment, stratification factors (the age group [≤ 50 and > 50], 
Baseline disease severity [T-VASI < 15 and ≥ 15], and status of active vitiligo 
[Yes/No]), Baseline, and all post-baseline visits of the outcome variable.  For 
T-VASI related endpoints, Baseline disease severity (T-VASI < 15 and ≥ 15) 
will not be included in the model.  The covariates included in the model and 
the order of these variables are consistent with the augmentation step.
●
For each monotone missing dataset, using SAS PROC MI with MONOTONE 
REG model statement, the outcome variable at each post-baseline visit with 
missing values will be imputed sequentially with covariates constructed from 
their corresponding sets of preceding variables.
A 'complete' dataset with imputed values for the missing data is generated after the 
augmentation and imputation steps are completed.
Repetition of Imputations (K)
Repetition of imputations, K, must be determined in advance.  When estimating the 
overall variance of multiple imputation, the additional sampling variance is the between-
imputation variance divided by K.  This value represents the sampling error associated 
with the overall or average coefficient estimates.  It is used as a correction factor for using 
a specific number of imputations.  The more imputations (K) are conducted, the more 
precise the parameter estimates will be.  For example, with a 1% power falloff tolerance 
 


Upadacitinib
M19-051 – Statistical Analysis Plan
Version 2.0 – 27 December 2022
47
in multiple imputation, as compared to an infinite number of imputations, multiple 
imputation requires 20 repetitions of imputation for 30% missing information and 
40 repetitions for 50% missing information.4  In the usual clinical settings expecting less 
than 30% missing information, K = 30 repetitions are deemed sufficient.  When 
missingness exceeds 30%, depending on the power falloff tolerance level, number of 
repetitions may need to be increased.  Recent research4 suggested that the number of 
repetitions (K) should be at least equal to the percentage of missing.6
2.4
Derivation of Response Status and Non-Responder 
Imputation
For each 'complete' dataset, the imputed post-baseline values will be rounded to the same 
precision as the observed data.  Response status (e.g., F-VASI 75 at each visit) will be 
determined accordingly.
The imputed response status for missing due to reasons other than COVID-19 or any other 
missing data that can be reasonably assumed to be Missing at Random will be overridden 
by non-responder imputation (Section 2.1) to ensure that multiple imputation is only 
applied to missing due to COVID-19 or any other missing data that can be reasonably 
assumed to be Missing at Random:
●
Using NRI approach, all missing due to reasons other than COVID-19 or any 
other missing data that can be reasonably assumed to be Missing at Random 
will be categorized as non-responders.  In addition, subjects whose 
change/percent change from Baseline cannot be calculated because of a 
missing Baseline will be considered as a non-responder at all post-baseline 
visits unless the post-baseline value is zero.
●
The only exception is that a subject will be categorized as a responder for the 
visit if the subject is a responder both before and after an SAP-specified visit 
window in Period 1.

Analysis
The statistical analysis will use the Cochran-Mantel-Haenszel (CMH) test adjusted by the 
stratification factors derived from actual values.
2.5.1
Analysis of Each Dataset
For each of the K 'complete' datasets, the CMH test will be used to estimate the treatment 
difference versus placebo and the corresponding standard error.
2.5.2
Synthesis of Results for Statistical Inference
The results from the K 'complete' datasets will be synthesized using the SAS procedure 
PROC MIANALYZE, following Rubin's formula (Rubin, 19875), to derive the MI 
estimator of the treatment difference for the final inferences.
Rubin's formula
We fit the analysis model to the kth 'complete' dataset, denoting the estimate of the 
treatment difference q by 5de from the kth 'complete' dataset, and denoting the 
corresponding estimate of the variance as Vk.
The MI estimator of q (point estimator obtained from PROC MIANALIZE), 5df, is the 
average of the K individual estimators:
5df = 1
g h 5de.
i
e"
The estimated variance of 5df, is a combination of the between- and within-imputation 
variability as follows:
jf =  + (1 +

i)k,
where  =

i ∑

is the within-imputation variability and k =

It has been shown1 that the statistic
l = 5df −5
mjf
has an approximate &n distribution where o = (g −1)(1 +
p
q)N.  Statistical inference, 
including hypothesis testing and confidence intervals for the treatment effect, will be 
based on this T-statistic.
