Brief summary:
The objective of this study is to evaluate the efficacy and safety of upadacitinib compared to placebo as induction therapy in adults with moderately and severely active Crohn's disease (CD).

Detailed description:
This study includes two parts:

* Part 1: a randomized double-blind placebo-controlled induction period and
* Part 2: an extended treatment period for non-responders from Part 1.

In Part 1, participants will be randomized in a 2:1 ratio to upadacitinib 45 mg once daily (QD) or matching placebo for 12 weeks. The randomization will be stratified by baseline corticosteroid use (yes or no), endoscopic disease severity (Simplified Endoscopic Score for Crohn's disease \[SES-CD\] \< 15 and ≥ 15), and number of prior biologics with prior inadequate response or intolerance (0, 1, \> 1).

Participants who do not achieve clinical response at Week 12 will be able to enroll in Part 2 to receive a double-blind extended treatment with upadacitinib until Week 24. Clinical response is defined as a ≥ 30% decrease in average daily very soft or liquid stool frequency (SF) and/or ≥ 30% decrease in average daily abdominal pain (AP) score (both not worse than Baseline).

Participants who achieve clinical response at Week 12 may be eligible to enter the 52-week, double-blind, maintenance portion of Study M14-430 (NCT03345823).

Arms: arm 1: Participants will receive placebo once daily for 12 weeks in Part 1. Clinical non-responders will receive 45 mg upadacitinib once daily for 12 weeks in Part 2. arm 2: Participants will receive 45 mg upadacitinib once daily for 12 weeks in Part 1. Clinical non-responders will receive 30 mg upadacitinib once daily for 12 weeks in Part 2.

Study Design and Objectives
2.1
Objectives, Hypotheses and Estimands
The objective of Study M14-433 is to evaluate the efficacy and safety of upadacitinib 
compared to placebo as induction therapy in subjects with moderately and severely active 
Crohn's Disease (CD).
Primary Efficacy Objective
For EU/EMA regulatory purposes, the primary efficacy objective of Study M14-433 is to 
evaluate the efficacy based on higher rates of clinical remission per patient reported 
outcomes (PROs) of very soft or liquid stool frequency and abdominal pain score, and 


Upadacitinib (ABT-494)
M14-433 – Statistical Analysis Plan
Version 4.0 – 22 January 2022
6
endoscopic response after 12 weeks of treatment with upadacitinib 45 mg once daily (QD) 
compared to placebo as induction therapy in subjects with moderately and severely active 
CD who have inadequately responded to or are intolerant to conventional and/or biologic 
therapies during the 12 week double-blind induction period (Part 1).
Hypotheses corresponding to the primary efficacy objectives and endpoints are:
●
The proportion of subjects achieving clinical remission per PROs at Week 12 
treated with upadacitinib 45 mg QD is greater than that treated with placebo, 
and
●
The proportion of subjects achieving endoscopic response at Week 12 treated 
with upadacitinib 45 mg QD is greater than that treated with placebo
For US/FDA regulatory purposes, the primary efficacy objective of Study M14-433 is to 
evaluate the efficacy based on higher rates of clinical remission per Crohn's Disease 
Activity Index (CDAI) and endoscopic response after 12 weeks of treatment with 
upadacitinib 45 mg QD compared to placebo as induction therapy in subjects with 
moderately and severely active CD who have inadequately responded to or are intolerant 
to conventional and/or biologic therapies during the 12 week double-blind induction 
period (Part 1).
Hypotheses corresponding to the primary efficacy objectives and endpoints are:
●
The proportion of subjects achieving clinical remission per CDAI at Week 12 
treated with upadacitinib 45 mg QD is greater than that treated with placebo, 
and
●
The proportion of subjects achieving endoscopic response at Week 12 treated 
with upadacitinib 45 mg QD is greater than that treated with placebo
The primary efficacy objectives will be assessed based on Intent-to-Treat (ITT) 
population, which consists of all randomized subjects who have received at least one dose 
of double-blinded study drug.


Upadacitinib (ABT-494)
M14-433 – Statistical Analysis Plan
Version 4.0 – 22 January 2022

The estimands corresponding to the primary efficacy objectives are defined as follows:
●
The difference in the proportion of subjects achieving clinical remission per 
PROs at Week 12 regardless of premature discontinuation of study drug but 
before initiation of CD-related confounding medications (See Section 8.1), and 
without initiation or dose escalation of CD-related corticosteroids (See 
Section 8.2) in the upadacitinib 45 mg QD and placebo groups in the ITT 
population (EU/EMA regulatory purposes).
●
The difference in the proportion of subjects achieving clinical remission per 
CDAI at Week 12 regardless of premature discontinuation of study drug but 
before initiation of CD-related confounding medications (See Section 8.1), and 
without initiation or dose escalation of CD-related corticosteroids (See 
Section 8.2) in the upadacitinib 45 mg QD and placebo groups in the ITT 
population (US/FDA regulatory purposes).
●
The difference in the proportion of subjects achieving endoscopic response at 
Week 12 regardless of premature discontinuation of study drug but before 
initiation of CD-related confounding medications (See Section 8.1), and 
without initiation or dose escalation of CD-related corticosteroids (See 
Section 8.2) in the upadacitinib 45 mg QD and placebo groups in the ITT 
population.
Secondary Efficacy Objectives
The secondary efficacy objectives of the Study M14-433 are to demonstrate higher 
efficacy of treatment with upadacitinib 45 mg QD when compared to placebo during the 
12-week double-blind induction period (Part 1) with respect to the ranked secondary 
endpoints specified in Section 3.2 in subjects with moderately and severely active CD 
who have inadequately responded to or are intolerant to conventional and/or biologic 
therapies.  The secondary efficacy objectives will be assessed based on ITT population.
Hypotheses corresponding to the ranked secondary efficacy objectives and endpoints are: 
for each of the ranked secondary endpoints except occurrence of hospitalizations due to 
CD during Part 1 (Section 3.2), greater proportion of subjects with improvement (or 


Upadacitinib (ABT-494)
M14-433 – Statistical Analysis Plan
Version 4.0 – 22 January 2022
8
greater mean change from Baseline for continuous endpoints) is achieved with 
upadacitinib 45 mg QD group when compared to that of placebo.  Hypothesis 
corresponding to occurrence of hospitalizations due to CD during Part 1 is: smaller 
proportion of subjects experience at least one occurrence of hospitalizations due to CD 
during Part 1 with upadacitinib 45 mg QD group when compared to that of placebo.
The estimands corresponding to the secondary efficacy objectives are defined for each of 
the binary ranked secondary endpoints except occurrence of hospitalizations due to CD 
during Part 1 as follows: The difference in the proportion of subjects achieving binary 
endpoints regardless of premature discontinuation of study drug but before initiation of 
CD-related confounding medications (See Section 8.1), and without initiation or dose 
escalation of CD-related corticosteroids (See Section 8.2) in the upadacitinib 45 mg QD 
and placebo groups in the ITT population.
The estimand corresponding to the secondary objective for occurrence of hospitalizations 
due to CD during Part 1 is as follows: The difference in the proportion of subjects with at 
least one occurrence of hospitalization due to CD during Part 1 regardless of premature 
discontinuation of study drug, and regardless of initiation or dose escalation of CD-related 
corticosteroids (See Section 8.2) in the upadacitinib 45 mg QD and placebo groups in the 
ITT population.
The estimands corresponding to the secondary efficacy objectives are defined for each of 
the continuous ranked secondary endpoints as follows: the difference in the mean change 
from baseline regardless of premature discontinuation of study drug but before initiation 
of CD-related confounding medications (See Section 8.1), and if subjects would not 
initiate or escalate dose of CD-related corticosteroids (See Section 8.2) in the upadacitinib 
45 mg QD and placebo groups in the ITT population.
2.2
Study Design Overview
This is a Phase 3, randomized, double-blind, placebo-controlled induction study to 
evaluate the efficacy and safety of upadacitinib, an orally administered JAK1 inhibitor in 


Upadacitinib (ABT-494)
M14-433 – Statistical Analysis Plan
Version 4.0 – 22 January 2022
9
adult subjects with moderately to severely active CD who have inadequately responded to 
or are intolerant to conventional and/or biologic therapies.
This study will enroll approximately 501 subjects at approximately 400 study centers 
worldwide.  Study M14-433 will enroll subjects who have had an inadequate response or 
intolerance to conventional therapies but have not failed biologic therapy (non-bio-IR 
population) and subjects who had an inadequate response or intolerance to one or more 
biologic agents for CD (bio-IR population).
Conventional therapy is defined as one or more of the following: oral locally-acting 
steroids (e.g., budesonide, beclomethasone), systemic corticosteroids (prednisone or 
equivalent), or immunosuppressives (e.g., azathioprine [AZA], 6 mercaptopurine [6-MP], 
methotrexate [MTX]).  Among subjects who failed conventional therapy, the study will 
allow the enrollment of approximately 20% of subjects who have used biologics for up to 
1 year and have discontinued for reasons other than inadequate response or intolerance 
(e.g., change of insurance/reimbursement, well-controlled disease, etc.).
The biologics approved for the treatment of CD include adalimumab, certolizumab, 
infliximab, ustekinumab and/or vedolizumab.  Within the bio-IR subjects, the study will 
allow enrollment of approximately 30% subjects who have had inadequate response or 
intolerance to 3 or more biologics.  The study will allow the enrollment of up to 10% of 
subjects who received a JAK inhibitor prior to study entry if they have not had inadequate 
response or loss of response.
The duration of the study could be up to 33 weeks and consists of the following periods:
1.
Screening period of up to a maximum of 35 days
2.
12-week randomized, double-blinded therapy induction period (Part 1) 
3.
12-week Extended Treatment Period for subjects who do not achieve clinical 
response at Week 12 of Part 1 (Part 2) 
4.
30-day follow up period for subjects who do not enroll into Study M14-430

The schematic of the study design is shown in Figure 1.
Figure 1.
M14-433 Study Design – Part 1 and Part 2
QD = once daily; Rand = randomization
Part 1
In Part 1, subjects (n=501) will be randomized in a 2:1 ratio to upadacitinib 45 QD or 
matching placebo for 12 weeks (Figure 1).  The randomization will be stratified by 
baseline corticosteroid use (yes or no), endoscopic disease severity (Simplified 
Endoscopic Score for Crohn's Disease (SES-CD) < 15 or ≥ 15) and number of prior 
biologics with prior inadequate response or intolerance (0, 1, > 1).  The data collected 
from subjects from Part 1 will be used for the primary efficacy analysis.
Visits during the study will occur at Baseline and Weeks 2, 4, 8, and 12/Premature
Discontinuation (PD) to collect clinical, endoscopic and laboratory assessments of disease 
activity.
At Week 12, subjects achieving clinical response, defined as ≥ 30% decrease in average 
daily very soft or liquid stool frequency (SF) and/or ≥ 30% decrease in average daily 


Upadacitinib (ABT-494)

11
abdominal pain (AP) score (both not worse than Baseline) may be eligible to the 52-week 
double-blind, maintenance portion of Study M14-430.
All subjects who do not achieve clinical response at Week 12 will be able to enroll in 
Part 2 (Extended Treatment Period) to receive a double-blind upadacitinib until 
Week 24/PD.
Subjects are not eligible to enter Study M14-430 until the ileo-colonoscopy procedure at 
Week 12 has been completed.  If the Coronavirus 2019 disease (COVID-19) pandemic 
precludes a subject from undergoing an endoscopy, the subject can enroll in 
Study M14-430 if clinical response was achieved at Week 12.
Part 2
Part 2 is a 12-week Extended Treatment Period consisting of 2 cohorts for subjects who 
do not achieve clinical response at Week 12 in Part 1.  The objectives of Part 2 are to offer 
blinded upadacitinib induction treatment to placebo non-responders from Part 1, and to 
evaluate delayed clinical response to upadacitinib in subjects who did not initially respond 
to upadacitinib during Part 1.
●
Cohort 1:  Subjects who received placebo during Part 1 and did not achieve 
clinical response at Week 12 are eligible to receive double-blind induction 
treatment with upadacitinib 45 mg QD for 12 weeks (until Week 24).
●
Cohort 2:  Subjects who received upadacitinib during Part 1 and did not 
achieve clinical response at Week 12 are eligible to receive double-blind 
upadacitinib 30 mg QD for 12 weeks (until Week 24).
Subjects in Part 2 will remain blinded to treatment to avoid unmasking the treatment 
received during Part 1.  The data collected from subjects from Part 2 will not be part of 
the primary efficacy analysis and will be reported separately in the clinical study report.


Upadacitinib (ABT-494)
M14-433 – Statistical Analysis Plan
Version 4.0 – 22 January 2022
12
Subjects are not eligible to enter in Part 2 until the Week 12 endoscopy has been 
completed.  Visits will occur at Weeks 16, 20 and 24/PD to collect clinical, endoscopic 
and laboratory assessments of disease activity.
During Part 2, subjects with persistent symptoms or worsening of CD may be 
discontinued at any time.
At Week 24, subjects who achieve clinical response may be eligible to enter 
Study M14-430.  Subjects are not eligible to enter Study M14-430 until the 
ileo-colonoscopy procedure at Week 24 for evaluation of mucosal inflammation has been 
completed.  If the COVID-19 pandemic precludes a subject from undergoing an 
endoscopy, a subject can enroll in Study M14-430.
Subjects who do not achieve clinical response at Week 24 will be discontinued from 
Study M14-433 and will receive standard of care treatment at investigator's discretion.  
Subjects who do not achieve clinical response at Week 24 and all subjects who 
prematurely discontinue the study will have a follow-up visit 30 days from the last dose of 
study drug to collect information on new or ongoing AEs and laboratory assessments.  
Subjects will be discontinued from the study if they withdraw consent or if they are 
deemed unsuitable to continue for any reason by the investigator.
2.3
Treatment Assignment and Blinding
At Baseline, 501 subjects will be randomized in a 2:1 ratio to upadacitinib 45 mg QD or 
matching placebo.  The randomization will be stratified by baseline corticosteroid use (yes 
or no), endoscopic disease severity (SES-CD < 15 or ≥ 15) and number of prior biologics 
with prior inadequate response or intolerance (0, 1, > 1).
Subjects who received placebo during Part 1 and did not achieve clinical response at 
Week 12 are eligible to enroll in Cohort 1 of Part 2 to receive double-blind induction 
treatment with upadacitinib 45 mg QD for 12 weeks (until Week 24).

Subjects who received upadacitinib during Part 1 and did not achieve clinical response at 
Week 12 are eligible to enroll in Cohort 2 of Part 2 to receive double-blind treatment with 
upadacitinib 30 mg QD for 12 weeks (until Week 24).
Subjects in Part 2 will remain blinded to treatment to avoid unmasking the treatment 
received during Part 1.
2.4
Sample Size Determination
The co-primary endpoints are achievement of clinical remission per PROs (EU/EMA) or 
per CDAI (US/FDA) at Week 12 and achievement of endoscopic response at Week 12.  
Sample size calculation is based on the maximum sample size needed to detect treatment 
difference for each of the co-primary endpoints.  The proposed assumptions were 
informed by the results of the 16-week clinical and endoscopic data of upadacitinib 
Phase 2 CD Study M13-740 and available published data with another investigational 
Janus Kinase 1 (JAK1) inhibitor.
For EU/EMA regulatory purposes:  Assuming a clinical remission per PROs rate of 15% 
in the placebo group and 33% in the upadacitinib group at Week 12, a total sample size of 
501 subjects randomized in a 2:1 ratio (334 subjects in the upadacitinib group and 
167 subjects in the placebo group) will be adequate to detect at least an 18% treatment 
difference in clinical remission per PROs rates at Week 12 between the treatment groups 
using Fisher's exact test with at least 95% power at a 0.05 two-sided significant level.
For US/FDA regulatory purposes:  Assuming a clinical remission per CDAI rate of 21.5% 
in the placebo group and 45% in the upadacitinib group at Week 12, this sample size will 
be adequate to detect at least a 23.5% treatment difference in clinical remission per CDAI 
rates at Week 12 between the treatment groups using Fisher's exact test with at least 95% 
power at a 0.05 two-sided significant level.
Assuming an endoscopic response rate of 11.5% in the placebo group and 28.5% in the 
upadacitinib group at Week 12, this sample size will be adequate to detect at least a 17% 
treatment difference in endoscopic response rates at Week 12 between the treatment

Analysis Populations
The following population sets will be used for the analyses.
Intent-to-Treat (ITT) Populations
The ITT population for the 12-week double blind induction period (Part 1) (denoted by 
ITT1) includes all randomized subjects who received at least one dose of double-blind 
study drug during Part 1.  The ITT1 population will be used for all efficacy and baseline 
analyses for Part 1.
For ITT1 population, subjects will be included in the analysis according to the treatment 
groups that they were randomized to.  The ITT population for the 12-week extension 
treatment period (Part 2) (denoted by ITT2) includes all subjects who have received at 
least one dose of study drug in Part 2.  The ITT2 population will be used for all efficacy 
and baseline analyses for Part 2.
Per-Protocol Population
The Per-Protocol (PP) population represents a subset of the ITT population, consisting of 
subjects that did not have a major protocol deviation.  Major protocol deviations leading 
to exclusion from the PP population will be identified prior to database lock.
For PP population, subjects will be included in the analysis according to the treatment 
groups that they were randomized to.
Safety Populations
The safety population for Part 1 (denoted by SA1) includes all subjects who received at 
least one dose of the study drug in Part 1.
The safety population for Part 2 (denoted by SA2) includes all subjects who received at 
least one dose of the study drug in Part 2.

The safety population for subjects who received upadacitinib in Part 1 and enrolled in Part 
2 (denoted by SA3).  SA3 is a subset of SA2 which includes Cohort 2 of SA2, defined as 
subjects who received upadacitinib in Part 1 and received at least one dose of study drug 
in Part 2.
The all upadacitinib safety population (SA-UPA) includes all subjects who received at 
least one dose of upadacitinib in Part 1 or Part 2.
For the safety populations, subjects are assigned to a treatment group based on the "as 
treated" treatment group, regardless of the treatment randomized.  The "as treated" will be 
determined by the most frequent dose regimen received in the analysis period.
5.0
Subject Disposition
A summary of subject accountability will be provided where the number of subjects in 
each of the following categories will be summarized for each treatment group for Part 1, 
and each cohort for Part 2:

●
Subjects who took at least one dose of study drug (Part 1 and Part 2);
●
Subjects who completed protocol-specified treatment (Part 1 and Part 2);
●
Subjects who prematurely discontinued study drug (Part 1 and Part 2);
●
Subjects who prematurely discontinued from study (Part 1 and Part 2).
Number and percentage of subjects who discontinued study drug and who withdrew from 
the study will be summarized by reason (primary reason and all reasons) for each 
treatment group within Part 1, and each cohort within Part 2.  Subjects with multiple 
reasons for premature discontinuation will be counted once in the calculation of the

Handling of Potential Intercurrent Events for the 
Primary and Key Secondary Endpoints
Potential intercurrent events considered in the Study M14-433 include 1) premature 
discontinuation of study drug and 2) initiation or dose escalation of CD-related 
corticosteroids defined in Section 8.2.  As suggested by Qu et al. (2021), a mix of 
strategies will be used to handle different intercurrent events for the efficacy analysis.
8.1
Intercurrent Event 1 (IE1): Premature Discontinuation of 
Study Drug
Following the intent-to-treaty (ITT) principle, a treatment policy strategy will be used to 
handle the IE1.  Data collected on/after premature discontinuation of study drug will be 
used for all efficacy endpoints.
The only exception is when data are collected on/after the date subjects switching to other 
treatment for CD, which will be handled as follows:
●
Binary endpoints other than the occurrence of hospitalization and/or the 
occurrence of CD-related surgery endpoints:  A composite strategy will be 
used in the efficacy analysis: the subject will be considered as non-responders 
at all visits on/after the initiation of other CD-related confounding medications.
●
Binary endpoints regarding the occurrence of hospitalization and/or the 
occurrence of CD-related surgery endpoints:  A treatment policy strategy 
will be used regardless.
●
Continuous endpoints:  A hypothetical strategy will be used in the efficacy 
analysis.  Data collected on/after the initiation of other CD-related confounding

M14-433 – Statistical Analysis Plan
Version 4.0 – 22 January 2022
30
medications will not be used in the analysis.  Efficacy analysis will be handled 
by using corresponding statistical models (e.g., the Mixed-Effect Model 
Repeated Measurement [MMRM] model).
The CD-related confounding medications include.
●
Biologics approved for CD (Adalimumab, Certolizumab, Infliximab, 
Ustekinumab, Vedolizumab, Natalizumab)
●
Any investigational compound
●
Systemic corticosteroids or locally acting steroids, rectal corticosteroid
●
Immunosuppressants (azathioprine, mercaptopurine, methotrexate, tacrolimus, 
cyclosporine)
8.2
Intercurrent Event 1 (IE1): CD-Related Corticosteroids
The CD-related corticosteroids intercurrent event is defined as follows.  
In Part 1:
1.
subjects not on CD-related corticosteroids (systemic or oral locally acting 
corticosteroids for CD) at baseline which are then initiated during Part 1
2.
a) subjects on CD-related corticosteroids at baseline who have dosages increased to 
greater than the prednisone equivalent dose taken at baseline until Week 10 or 
b) subjects with any dose increase in CD-related corticosteroids between Week 10 
and Week 12
3.
subjects not on rectal corticosteroid at baseline who initiated rectal corticosteroids 
during Part 1, regardless of rectal corticosteroid dose
4.
subjects on rectal corticosteroids at baseline who have the dosage increased to 
greater than the dose taken at baseline during Part 1;
5.
subjects on rectal corticosteroids at baseline and initiated different rectal 
corticosteroids during Part 1, regardless of rectal corticosteroid dose

In Part 2:
1.
subjects not on CD-related corticosteroids (systemic or oral locally acting 
corticosteroids for CD) at baseline which are then initiated during Part 2 
2.
a) subjects on CD-related corticosteroids at baseline who have dosages increased to 
greater than the prednisone equivalent dose taken at baseline and Week 12 until 
Week 22 or 
b) subjects with any dose increase in CD-related corticosteroids between Week 22 
and Week 24
3.
subjects not on any rectal corticosteroid at baseline and during Part 1 who initiated 
rectal corticosteroids during Part 2, regardless of rectal corticosteroid dose
4.
subjects on rectal corticosteroids at baseline or during Part 1 who have dosage 
increased to greater than the dose taken at baseline during Part 2;
5.
subjects on rectal corticosteroids at baseline or during Part 1, and initiated different 
rectal corticosteroids during Part 2, regardless of rectal corticosteroid dose
The time point of the CD-related corticosteroids intercurrent event is defined as the date 
when one of the scenarios above occurs for a subject.
Binary endpoints other than the occurrence of hospitalization and/or the occurrence 
of CD-related surgery endpoints:  A composite strategy will be used in the efficacy 
analysis: the subject will be considered as non-responders at all visits on/after the 
initiation of CD-related corticosteroids.
Binary endpoints regarding the occurrence of hospitalization and/or the occurrence 
of CD-related surgery endpoints:  A treatment policy strategy will be used regardless.
Continuous endpoints: A hypothetical strategy will be used in the efficacy analysis.

Efficacy Analyses
9.1
General Considerations
The primary and secondary efficacy endpoints as specified in Section 3.0 will be analyzed 
based on ITT1 for Part 1.  The difference between treatment groups for the primary and 
secondary efficacy endpoints will be tested with graphical multiplicity adjustment1 to 
ensure a strong control of family-wise type I error rate at significance level alpha = 0.05 
(2-sided) (see Section 12.0).  Analyses of other efficacy endpoints for Part 1 will be 
performed using ITT1 at significance level alpha = 0.05 (2-sided) without multiplicity 
adjustment.
No statistical comparisons will be performed for Part 2.
For all efficacy endpoints, the descriptive statistics will be provided by treatment group 
for Part 1, and by cohort for Part 2.  The statistics include number of observations, mean, 
standard deviation, 95% CI, minimum, median, and maximum for continuous variables, 
and number, percent and two-sided 95% CI for discrete variables.  And number of 
subjects with missing data due to COVID-19 pandemic will be summarized for primary 
and secondary efficacy endpoints.
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.
The Primary Analysis will be performed after all enrolled subjects have completed Part 1 
and Part 2, and the database has been locked.  This will be the only and final efficacy 
analysis.
"Baseline" refers to the last non-missing observation prior to the first administration of 
study drug in Part 1 or prior to the randomization if no study drug is given.

Analysis of Categorical Variables:
For categorical variables, frequencies and percentages will be reported for each treatment 
group in Part 1, and for each cohort in Part 2.  Comparison of upadacitinib group and 
placebo group will be performed using the Cochran Mantel-Haenszel (CMH) test 
adjusting for stratification factors (baseline steroid use (Yes, No), endoscopic disease 
severity (SES-CD < 15, ≥ 15) and number of prior biologics with prior inadequate 
response or intolerance (0, 1, > 1)).  If there is a stratum for a treatment group that has no 
subject in it, a value of 0.1 will be added to all cells in the corresponding table in order to 
prevent dividing by 0, as suggested in Greenland and Robins (1985).2  Point estimates and 
95% confidence interval (CI)s for the difference in proportions between upadacitinib 
group and placebo group will be provided.  Construction of CI for the common risk 
difference will be based on the Mantel-Haenszel estimate adjusting for stratification 
factors.
For endpoints with small sample size (such as resolution draining fistulas at Week 12 in 
subjects with draining fistulas at Baseline) or small number of responders (e.g., 
occurrence of CD-related hospitalizations during Part 1), comparison of upadacitinib 
group and placebo group will be performed using the Chi-Square test (or Fisher's exact 
test if more than 20% of the cells have expected counts of less than 5).
Analysis of Continuous Variables:
For continuous variables, the model based mean and standard error will be provided.  The 
mean value of the variable at baseline and each scheduled visit will also be presented for 
each treatment group.  Continuous variables collected longitudinally will be using a 
Mixed-Effect Model Repeated Measurement (MMRM) model.  Continuous efficacy 
variables which are collected at only one post-baseline visit (such as SES-CD) will be 
analyzed using an Analysis of Covariance (ANCOVA) model.  Point estimates and 95% 
CIs of mean change from baseline within each treatment group, and the difference 
between upadacitinib group and placebo group will be provided.

9.2
Handling of Missing Data
Missing data could occur due to various reasons, including missing visits/assessments, 
early withdrawal from the clinical trials, or missing due to COVID-19 infection or logistic 
restrictions during the pandemic. Assessments on or after any intercurrent event will be 
handled as specified in Section 8.0.
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.  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.  The intent is to provide reliable estimates of the 
treatment effects under the scenario without the impact of COVID-19 pandemic.
Missing data for the efficacy analyses will be handled using the methods described below.
9.2.1
Categorical Endpoints
For binary efficacy endpoints, other than the occurrence of hospitalization and the 
occurrence of CD-related surgery, missing data will be handled using the following 
approaches:
●
The primary approach for handling missing data in the analysis of binary 
endpoints will use Non-Responder Imputation (NRI) while incorporating 
Multiple Imputation (MI) to handle missing data due to COVID-19 (NRI-C).
○
The NRI-C 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.  


Upadacitinib (ABT-494)
M14-433 – Statistical Analysis Plan
Version 4.0 – 22 January 2022
35
The only exception is that missing data due to COVID-19 infection or 
logistical restriction will be handled by MI.  At each visit, subjects will be 
characterized as responders or non-responders based on MI imputed values 
if missing due to COVID-19; otherwise, subjects will be considered as 
non-responders for missing due to other reasons in the NRI-C approach.  In 
addition, at and after the CD-related corticosteroids intercurrent event (see 
Section 8.2) and on/after the date of initiation of CD-related confounding 
medications after premature discontinuation of study drug 
(see Section 8.1), subjects will be considered non-responders and will not 
be imputed by MI.
●
A sensitivity analysis for binary endpoints will use NRI with No special data 
handling for missing due to COVID-19 (NRI-NC).
○
NRI-NC will be performed in the same way as NRI-C without the 
exception above.  Missing due to COVID-19 infection or logistical 
restriction will also be counted as non-responders.  Subjects at or after the 
occurrence of the CD-related corticosteroids intercurrent event and on/after 
the date of initiation of CD-related confounding medications after 
premature discontinuation of study drug will still be considered as non-
responders.  This is the same method as "NRI" as defined in the protocol.
●
Details on MI method are described below:
○
Markov Chain Monte Carlo (MCMC) will be first applied to augment data 
into monotonic missing pattern (where applicable), and PROC MI will be 
used to generate 30 datasets using the regression method.  If the binary 
endpoints are derived from the continuous variables, PROC MI will be 
applied to the continuous variables.  The variables to be included in the 
imputation model are: treatment group, randomization stratification factors 
(baseline steroid use (Yes, No), endoscopic disease severity (SES-CD 
< 15, ≥ 15) and number of prior biologics with inadequate response or 
intolerance (0, 1, > 1)), age, gender, weight, baseline measurement (if 
applicable) and post-baseline measurements at each visit up to the end of 
the analysis period.  The random seed for MCMC and the random seed for 
PROC MI are specified in Appendix I.  The imputed post-baseline 
measurements will be rounded to the same precision as the observed data 
before the determination of responder status.  Subjects will be 


Upadacitinib (ABT-494)
M14-433 – Statistical Analysis Plan
Version 4.0 – 22 January 2022
36
characterized as responders or non-responders based on MI imputed data.  
Using the CMH model adjusted by randomization stratification factors, the 
endpoints will be analyzed using each of the 30 imputed datasets.  SAS 
PROC MIANALYZE will be used to generate the final inferences of the 
risk difference between upadacitinib group and placebo group, using 
Rubin's rule3.  Note that measurements will be set to missing for 1) at or 
after the occurrence of the CD-related corticosteroids intercurrent event 2) 
on/after the date of initiation of CD-related confounding medications after 
premature discontinuation of study drug before applying MI.  After the MI 
imputation, an NRI override will be implemented for missing values 1) due 
to reasons other than COVID-19 infection or logistic reasons, or 2) at or 
after the occurrence of the CD-related corticosteroids intercurrent event or 
3) on/after the date of initiation of CD-related confounding medications 
after premature discontinuation of study drug, that is, regardless of MI 
imputed values, subjects satisfying 1) or 2) or 3) will be considered as 
"non-responder" for binary efficacy endpoints.
●
For binary efficacy endpoints regarding the occurrence of hospitalization and 
the occurrence of CD-related surgeries, missing data will be handled using the 
following approaches.
○
As observed analysis (AO): The AO analysis will not impute values for 
missing evaluations, and thus a subject who does not have an evaluation on 
a scheduled visit will be excluded from the AO analysis for that visit.  AO 
will include all values collected in the study.
9.2.2
Continuous Endpoints
For continuous efficacy endpoints where Mixed-Effect Model Repeat Measurement 
(MMRM) analysis or Analysis of Covariance (ANCOVA) is performed, missing data will 
be handled using the following approaches.
●
MMRM:  The repeat measurement analysis will be conducted using a mixed 
model including observed measurements at all post-baseline visits up to the end 
of the analysis period.  The mixed model includes the categorical fixed effects 
of treatment, visit and treatment-by-visit interaction, stratification factors at 


Upadacitinib (ABT-494)
M14-433 – Statistical Analysis Plan
Version 4.0 – 22 January 2022
37
randomization, and the continuous fixed covariates of baseline measurement.  
An unstructured variance covariance matrix will be used.  If the model cannot 
converge, an appropriate variance-covariance structure matrix (e.g., 
autoregressive or compound symmetry) will be used.  Parameter estimation is 
based on the method of restrictive maximum likelihood (REML).  MMRM will 
be the primary approach in the analysis of continuous variables with repeated 
measurements.
●
ANCOVA: For continuous efficacy variables that are collected at only one 
post-baseline visit (such as SES-CD), ANCOVA will be used.  The model 
includes the categorical fixed effects of treatment, stratification factors at 
randomization, and the continuous fixed covariates of baseline and 
measurement.
9.2.3
Additional Analyses
In addition, As Observed (AO) and tipping point analysis will be performed as 
supplementary and sensitivity analyses, if appropriate, for categorical or continuous 
endpoints.
●
AO: The AO analysis will not impute values for missing evaluations, and thus 
a subject who does not have an evaluation on a scheduled visit will be excluded 
from the AO analysis for that visit.  AO will include all values collected in the 
study.
●
Tipping Point Analysis for Binary Endpoints
The tipping point analyses are two-dimensional, i.e., assumptions about the 
missing outcomes on each of the upadacitinib group and the placebo group can 
vary independently.  The response rate among those subjects with missing 
response is assumed to be p0 for placebo group and p1 for upadacitinib group, 
and the response rate p0 and p1 systematically vary from 0% to 100% by every 
10% respectively.  Given a set of (p0, p1), the subjects with missing response 
will be randomly assigned as responders or non-responders using binomial 
distribution to generate 30 imputed datasets, and the same CMH method used 
for the primary analysis will be performed on each of the imputed datasets to 
obtain the results for each comparison between the upadacitinib group versus 


Upadacitinib (ABT-494)
M14-433 – Statistical Analysis Plan
Version 4.0 – 22 January 2022
38
the placebo group.  SAS PROC MIANALYZE will be used to generate the 
final inferences of the risk difference between upadacitinib group and placebo 
group, using Rubin's rule.3
If one pair of (p0, p1) is found to reverse the study result interpretation in 
terms of p-value larger than 0.05, then the (p0, p1) is identified as the tipping 
point.  The results for a grid of (p0, p1) combinations are provided in tabular 
format.  Note that missing data 1) on or after the occurrence of the CD-related 
corticosteroids intercurrent event or 2) on/after the date of initiation of CD-
related confounding medications after premature discontinuation of study drug 
will be considered as non-responders and will not be imputed in the tipping 
point analysis.
●
Tipping Point Analysis for Continuous Endpoints
The tipping point analyses are two-dimensional, i.e., assumptions about the 
missing outcomes on each of the upadacitinib group and the placebo group can 
vary independently.  In addition, the focus is on scenarios where missing 
outcomes on upadacitinib are worse than the imputed values on upadacitinib, 
while missing outcomes on placebo are better than the imputed values on 
placebo.  Missing values are first imputed via MI under MAR assumption, and 
then a shift parameter is applied to the imputed values (a different shift 
parameter may be specified for each treatment group).  This is implemented by 
PROC MI using the MNAR statement.  The imputation uses a two-step 
approach, augmentation step using MCMC and imputation step using 
Monotone Regression.  The MNAR statement is applied in the imputation 
step.  The number of imputed datasets is 30.
In cases where the shifted values are smaller than the minimum or larger than 
the maximum value of the endpoint, (i.e., out of range), the minimum or 
maximum value of the endpoint is used in further analysis steps.  For each pair 
of shift parameters, the same MMRM/ANCOVA method used for the primary 
analysis will be performed on each of the imputed datasets to obtain the results 
for each upadacitinib treatment group versus the placebo group comparison.  
These results will be aggregated using Rubin's rule.3

●
If a pair of shift parameters is found to reverse the study result interpretation in 
terms of p-value larger than 0.05, then the pair of shift parameters is identified 
as the tipping point.

Co-Primary Efficacy Endpoints and Analyses
9.3.1
Co-Primary Efficacy Endpoints
The co-primary endpoints for the primary analysis of efficacy are:
For EU/EMA regulatory purposes:
●
Achievement of clinical remission per PROs at Week 12, and
●
Achievement of endoscopic response at Week 12
For US/FDA regulatory purposes:
●
Achievement of clinical remission per CDAI at Week 12, and
●
Achievement of endoscopic response at Week 12
9.3.2
Primary Analysis of Co-Primary Efficacy Endpoints
The attributes of the estimands corresponding to the co-primary efficacy endpoints are 
summarized in Table 1.
The co-primary endpoints will be analyzed between upadacitinib group and placebo group 
using the CMH test, stratified by the randomization factors (baseline steroid use (Yes, 
No), endoscopic disease severity (SES-CD < 15, ≥ 15) and number of prior biologics with 
prior inadequate response or intolerance (0, 1, > 1)) based on ITT1.
Both of the co-primary efficacy endpoints (EU/EMA: 1a and 2, US/FDA: 1b and 2) will 
be tested at two-sided significance level of 0.05.  A CMH based two-sided 95% CI for the 
difference between treatment groups will be constructed.

NC and tipping point analysis.
In addition, sensitivity analyses which are based on "9-2 approach" (as detailed in 
Appendix D to calculate CDAI score and average daily SF/AP will be performed on 
primary endpoints:
●

A supplementary analysis of the co-primary endpoints corresponded to the AO analysis 
specified in Section 9.2 will be performed in which all data after IE1 and IE2 will be used.  
CMH analysis as detailed in Section 9.1 will be repeated using AO data handling without 
any imputation as an additional analysis.  The analysis will be conducted on the ITT1 
population who have the efficacy measurement at Week 12 visit.
9.3.4
Additional Analyses of the Co-Primary Efficacy Endpoints
NRI-C analysis for the co-primary endpoints will also be conducted on the PP population.  
In this analysis, subjects with deviations that could potentially impact the analysis of 
primary endpoint will be excluded.  The criteria will be fully defined in the classification 
plan.  Exclusion of subjects will be adjudicated by the therapeutic area medical director 
(TAMD) and reasons for the subjects to be excluded will be documented and finalized 
before the Induction Study database lock for the primary analysis.  Treatment difference 
between upadacitinib 45 mg QD and placebo with point estimate and 95% CI will be 
presented using NRI-C approach with the CMH method as detailed in Section 9.1 and 
Section 9.2.
9.4
Secondary Efficacy Analyses
9.4.1
Main Analyses of Ranked Secondary Efficacy Endpoints
The attributes of the estimands corresponding to the ranked secondary efficacy endpoints 
are summarized in Table 2.
In general, continuous secondary efficacy variables with repeated measurements will be 
analyzed using a MMRM model including factors for treatment group, visit, visit by 
treatment interaction, and stratification variables.  The MMRM analysis is considered 
primary for inferential purposes.  Continuous secondary efficacy variables which are 
collected at only one post-baseline visit (such as SES-CD) will be analyzed using 
ANCOVA approach.
Categorical secondary efficacy variables will be analyzed using the CMH test controlling 
for stratification factors (baseline steroid use (Yes, No), endoscopic disease severity 


Upadacitinib (ABT-494)

(SES-CD < 15, ≥ 15) and number of prior biologics with prior inadequate response or 
intolerance (0, 1, > 1)).  A CMH based two-sided 95% CI for the difference between 
treatment groups will be constructed.  NRI-C method for missing data will be used for 
categorical secondary endpoints except occurrence of hospitalizations due to CD during 
Part 1.  The endpoints of "Occurrence of hospitalization due to CD during Part 1" will be 
analyzed using Chi-square test (or Fisher's exact test if ≥ 20% of the cells have expected 
cell count < 5).
The NRI-C method will be the primary approach for missing data handling for categorical 
secondary endpoints except hospitalization due to CD during Part 1.  The endpoint of " 
Occurrence of hospitalization due to CD during Part 1" will be analyzed based on the 
observed data using AO approach only.

Sensitivity and Supplementary Analyses for Key Secondary 
Efficacy Endpoints
For categorical key secondary endpoints except occurrence of hospitalizations due to CD 
during Part 1, sensitivity analyses of the of the main analyses of are NRI-NC, and tipping 
point analysis.  NRI-NC will be performed for all categorical key secondary endpoints 
except occurrence of hospitalizations due to CD during Part 1
For continuous key secondary endpoints, sensitivity analysis of the of the main analysis is 
PMM.  
A supplementary analysis of categorical key secondary endpoints except occurrence of 
hospitalizations due to CD during Part 1 corresponded to the AO analysis specified in

Section 9.2 will be performed in which all data after IE1 and IE2 will be used.  CMH 
analysis as detailed in Section 9.1 will be repeated using AO data handling without any 
imputation as an additional analysis.  The analyses will be conducted on the ITT1 
population who have the efficacy measurement at corresponding visit for the endpoint.
9.5
Additional Efficacy Analyses
Part 1
Other efficacy endpoints will be analyzed similarly as the secondary efficacy endpoints as 
described in Section 9.4.  No multiplicity adjustment will be considered.  
Part 2
Only descriptive statistics will be provided for the Part 2 endpoints specified in 
Section 3.3 using the ITT2 by cohort.  Categorical endpoints will be summarized by 
number, percent and two-sided 95% CI; and continuous endpoints will be summarized by 
n, mean, standard deviation, 95% CI, minimum value, median, and maximum value; and 
time to response endpoints will be summarized by n, number of events, and the 25%, 
50%, 75% percentiles of time (in days).
A programming error from the ediary vendor was identified in the total number of daily 
stools question on patient ediaries that does not allow the transaction to progress if the 
answer 0 to question 1, "How many stools in total have you had in the last 24 hours from 
last record until now?"  The vendor has confirmed the issue was only present in languages 
that are translated from right to left.  For this program, that includes Hebrew and Arabic in 
Israel and Egypt, respectively.
Since data from total stool frequency is only applicable to non-ranked additional efficacy 
endpoints, a sensitivity analysis will be performed for the additional efficacy endpoint of 
change from Baseline in average daily total stool frequency at all scheduled visits, by 
excluding subjects from Egypt and Israel.

characteristics, subgroup analysis will be performed for the co-primary endpoints for the 
subgroups listed in Table 3 below using ITT1.  
For subgroup analysis, point estimate and 95% CI for each treatment group as well as
point estimate and 95% CI for treatment differences between upadacitinib group and 
placebo group will be presented.  No p-value will be provided.  If, for a subgroup factor 
except age, sex and race (Table 3), any of the resulting categories has fewer than 10% of 
the planned study size, subgroup analyses will not be presented for that category.

Safety Analyses
10.1
General Considerations
Safety analyses will be performed on the safety population for Part 1 (SA1) and SA-UPA 
population as defined in Section 4.0.  In addition, safety summaries will be performed on 
the safety analysis set for Part 2 (SA2) by cohort.
The standard safety analyses will include reporting of adverse events (AEs), adverse 
events of special interest (AESIs), laboratory, and vital signs measurements.  Frequency 
tables and exposure adjusted event rate per 100 patient-years tables of subjects with 
treatment-emergent adverse events (TEAEs) by system organ class (SOC) and by 
preferred term (PT) as in the Medical Dictionary for Regulatory Activities (MedDRA) 
dictionary will be provided by treatment group.  All continuous laboratory parameters and 
vital signs variables at each visit will also be summarized by treatment group.  Frequency 
tables of subjects meeting criteria for potentially clinically important vital sign values and 
for potentially clinically important laboratory values will be provided by treatment group.
The baseline for safety analysis will be treatment dependent.  For the Part 1 laboratory 
and vital signs measurements, the baseline value is defined as the last available 
measurement before study drug administration for all subjects.  Starting from the Part 2, 
the baseline value for subjects initially randomized to upadacitinib will remain the same.  
However, the baseline value for subjects initially randomized to placebo will be redefined 
as the last available measurement before first dose of upadacitinib administration in 
Part 2.
For the safety analysis, subjects are assigned to a treatment group based on the treatment 
actually received, regardless of the treatment randomized.
Missing safety data will not be imputed.

Adverse Events
AEs will be summarized and presented using primary MedDRA SOCs and PTs according 
to the version of the MedDRA coding dictionary used for the study at the time of database 
lock.  The actual version of the MedDRA coding dictionary used will be noted in the AE 
tables and in the clinical study report.  Specific AEs 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 severity and level of relationship to 
investigational product will be reported.
10.2.1
Treatment-Emergent Adverse Events
Part 1 (SA1 population): TEAEs for Part 1 are defined as events that begin either on or 
after the first dose of the study drug in Part 1 and until (i) the first dose of study drug in 
the Study M14-430 (if applicable), or (ii) until first dose of study drug in Part 2 (if 
applicable), or (iii) within 30 days after the last dose administration of the study drug in 
Part 1, whichever is earlier.
Part 2 (SA2 population):  TEAEs for Part 2 are defined as events that begin either on or 
after the first dose of the study medication in the Part 2 and until (i) first dose of study 
drug in the Study M14-430 (if applicable), or (ii) within 30 days after the last dose of the 
study drug in the Part 2, whichever is earlier.
All Upadacitinib:  TEAEs for "All Upadacitinib" are defined as events that begin either 
on or after the first dose of upadacitinib and (i) until first dose of study drug in the 
Study M14-430 (if applicable), or (ii) within 30 days after the last dose of upadacitinib in 
the study, whichever is earlier.
24-Week Upadacitinib (SA3 population):  TEAEs for "24-Week Upadacitinib" (SA3) 
are defined as events that begin either on or after the first dose of upadacitinib and until 
(i) first dose of study drug in the Study M14-430 (if applicable), or (ii) within 30 days 
after the last dose of upadacitinib in the study, whichever is earlier.

If an incomplete onset date was collected for an adverse event, the event will be assumed 
to be treatment-emergent unless there is other evidence that confirms that the event was 
not treatment-emergent (e.g., the event end date was prior to the study drug start date).  
The number and percentage of subjects experiencing TEAEs will be summarized.  For 
Part 1, the risk difference and 95% CI between upadacitinib group and placebo group will 
be presented.
10.2.2
Adverse Event Overview
An overview of AEs will be presented consisting of the number and percentage of 
subjects experiencing at least one event for each of the following AE categories: 
●
Any TEAE
●
Any TEAE of COVID-19
●
Any TEAE that was rated as related to study drug by the investigator.
●
Any severe TEAE
●
Any serious TEAE.
●
Any TEAE leading to discontinuation of study drug.
●
Any TEAE leading to death.
●
Treatment-emergent AESI (Appendix B).
●
All deaths
○
Deaths occurring ≤ 30 days after last dose of study drug
○
Deaths occurring > 30 days after last dose of study drug
○
Deaths related to COVID-19
In addition, an overview of AEs per 100 patient-years of study exposure will be presented 
for the AE categories defined above.  The number of TEAEs reported, the total number of 
years of study drug exposure, and the TEAE rate per 100 patient-years will be presented.

10.2.3
Treatment-Emergent Adverse Events by SOC and/or PT
TEAEs will be summarized by SOC and PT; by maximum relationship to study drug as 
assessed by the investigator (e.g., reasonable possibility or no reasonable possibility) and 
SOC and PT; by maximum severity and SOC and PT; and by subject number and SOC 
and PT.  Specific AEs will be counted once for each subject for calculating percentages, 
unless stated otherwise.  In addition, if the same AE occurs multiple times within a 
subject, the highest severity and level of relationship to investigational product will be 
reported.  The SOCs will be presented in alphabetical order, and the PTs will be presented 
in alphabetical order within each SOC.
For summary by maximum severity, if a subject has an AE with an unknown severity, 
then the subject will be counted in the severity category of unknown, even if the subject 
has another occurrence of the same event with a severity present.  The only exception is if 
the subject has another occurrence of the same AE with the most extreme severity –
severe.  In this case, the subject will be counted under the severe category.
For summary by maximum relationship to study drug, if a subject has an AE with an 
unknown relationship, then the subject will be counted in the relationship category of 
"unknown," even if the subject has another occurrence of the same event with a 
relationship present.  The only exception is if the subject has another occurrence of the 
same AE with a relationship assessment of "Reasonable Possibility."  In this case, the 
subject will be counted under the "Reasonable Possibility" category.
In addition, TEAEs will be summarized by PT and sorted by decreasing frequency for the 
upadacitinib group.

Analysis of Laboratory Data
Data collected from central and local laboratories, including additional laboratory testing 
due to an SAE, will be used in all analyses, except for baseline where SAE-related 
laboratory assessments on or before the first dose of study drug will be excluded.  The 
clinical laboratory tests defined in the protocol (e.g., hematology and clinical chemistry) 
will be summarized.
Analysis of Quantitative Laboratory Parameters
Each laboratory variable will be summarized for all time points (starting at baseline) with 
the number of non-missing observations, mean, standard deviation, median, minimum and 
maximum.  Mean change from Baseline to each applicable post-baseline visit will be 
summarized for selected laboratory variables, with the number of observations, baseline 
mean, and visit mean.  The change from baseline mean, standard error, and 95% CI will 
be presented for the mean change from Baseline within each treatment group.
For SA1 population, treatment group differences between upadacitinib group and placebo 
group for changes from baseline will be analyzed using a one-way Analysis of Variance

(ANOVA) model with treatment as a fixed factor and 95% CI for treatment difference 
will be presented for selected laboratory parameters.
Shift Table Analyses
Changes in laboratory parameters will be tabulated using shift tables categorized as low, 
normal, or high based on the normal ranges of the laboratory used for each sample.  A 
shift table from baseline to minimum and maximum value (based on normal range) will 
be created.  A similar shift table will be provided to summarize shifts from baseline to the 
final post-baseline value.
Potentially Clinically Significant Laboratory Values
The criteria for potentially clinically significant laboratory values will be determined by 
CTCAE criteria of Grade 3, Grade 4 and ≥ Grade 3, with a grade worsening compared to 
baseline.  Toxicity grading scale is based on National Cancer Institute Common Toxicity 
Criteria (NCI CTC) AE version 4.03.  The number and percentage of subjects meeting the 
criteria for potentially clinically significant laboratory values will be summarized by 
treatment group.  Listings of subject-level laboratory data will be provided for subjects 
meeting the criteria.
Assessment of Liver Elevations
The liver-specific laboratory tests include the serum glutamic pyruvic transaminase 
(SGPT/ALT), serum glutamic-oxaloacetic transaminase (SGOT/AST), alkaline 
phosphatase (ALP), and total bilirubin (TBL).  The frequencies and percentages of 
subjects with post baseline liver specific function test values that meet the following 
criteria of potential clinical interest will be summarized by treatment group:
●
ALT > 3 × ULN
●
ALT > 5 × ULN
●
ALT > 10 × ULN
●
ALT > 20 × ULN

●
ALT and/or AST > 3 × ULN and TBL > 2 × ULN,
where ULN is the upper normal limit.  The maximum ratio relative to the ULN will be 
used to determine if subjects meet any of the criteria listed above.
A listing of possible Hy's Law cases, defined as those meeting the following criteria will 
also be provided:
●
ALT and/or AST > 3 × ULN and TBL > 1.5 × ULN
In addition, eDISH plots will be created displaying post-baseline total bilirubin versus 
post-baseline ALT, in terms of the maximum ratio relative to the ULN (not necessarily 
concurrent).
10.4
Analysis of Vital Signs
Vital sign measurements of systolic and diastolic blood pressure, pulse rate, body weight, 
respiratory rate and body temperature will be summarized.
Each vital sign variable will be summarized for all time points (starting with Baseline) 
with the number of non-missing observations, mean and standard deviation, median, 
minimum and maximum.  Mean change from Baseline to each applicable post-baseline 
visit will be summarized for each vital sign variable, with the number of observations, 
Baseline mean, and visit mean.  The change from Baseline mean, standard error, and 
95% CI will be presented for the mean change from Baseline within each treatment group.

group for changes from Baseline will be analyzed using a one-way Analysis of Variance 
(ANOVA) with treatment as a fixed factor and 95% CI for treatment difference will be 
presented for each vital sign variable.
Vital sign variables will be evaluated based on potentially clinically important (PCI) 
criteria (Appendix C).  For each vital sign PCI criterion, the number and percentage of 
subjects who have a vital sign value meeting the criteria will be summarized.  Listings 
will be provided to summarize subject-level vital sign data for subjects meeting PCI 
criteria.

Interim Analyses
There will be no efficacy interim analyses planned for this study.
11.1
Data Monitoring Committee
An external data monitoring committee (DMC) composed of persons independent of 
AbbVie and with relevant expertise in their field will review unblinded safety data from 
the ongoing study.  The primary responsibility of the DMC will be to protect the safety of 
the subjects participating in this study.
A separate DMC charter describes the roles and responsibilities of the DMC members, 
frequency of data reviews, relevant data to be assessed, and general operations.
Since there are no efficacy analyses for early stopping, no alpha adjustment is needed.
12.0
Overall Type-I Error Control
The overall type I error rate of the co-primary and ranked secondary endpoints will be 
strongly controlled using a fixed sequence multiple-testing procedure1 as well as Holm 
procedure4 as described below.  Specifically, the testing will utilize the sequence of 
hypothesis testing for the co-primary endpoints followed by a set of ranked key secondary 
endpoints (Group 1A-E for EU/EMA, Group 1A-F for US/FDA) in the order as specified

in Section 3.2, and will begin with testing each of the co-primary endpoints using two-
sided α of 0.05.  If both of the co-primary endpoints are statistically significant at two-
sided 0.05 level of significance, the Group 1A (Group 1A-E for EU/EMA, Group 1A-F 
for US/FDA) ranked secondary endpoints will be tested at two-sided α of 0.05 in the order 
specified in Section 3.2.  If the co-primary endpoints and the Group 1A (Group 1A-E for 
EU/EMA, Group 1A-F for US/FDA) ranked secondary endpoints are statistically 
significant at two-sided 0.05 level of significance, the Group 1B (Group 1B-E for 
EU/EMA, Group 1B-F for US/FDA) ranked secondary endpoints will be tested using the 
Holm procedure at two-sided α of 0.05.  The graphs for the testing procedures are 
provided in Figure 2 (for EU/EMA regulatory purpose) and Figure 3 (for US/FDA 
regulatory purpose).

Crohn's Disease Activity Index (CDAI)
The Crohn's Disease Activity Index (CDAI) is a composite instrument that includes 
patient symptoms evaluated over 7 days (abdominal pain, stool frequency and general 
well-being), as well as physical and laboratory findings.  These items are scored 
individually, weighted, and do not contribute equally to the overall score.  The CDAI is 
derived from summing up the weighted individual scores of eight items as outlined below:

Higher CDAI scores indicate more severe disease.  For the calculation of CDAI and 
components (daily stool frequency, abdominal pain score and general well-being) at each 
visit, the following rules will be applied:


Upadacitinib (ABT-494)
M14-433 – Statistical Analysis Plan
Version 4.0 – 22 January 2022
70
1.
Identify the visit date with CDAI components that are collected, and set it as the 
CDAI calculation date.
2.
Calculate the subtotal scores from the component 1-3 (liquid or very soft stool 
frequency, abdominal pain score and general well-being) as follows:
a.
"14-4 approach"
i. Select the diary data from 14 days prior to the CDAI calculation date, and 
set the data from the 4 days (the day prior to, on the day of and two days 
after the endoscopy date) to missing;
ii. Take non-missing diary data from 7 most recent days from step i.  If there 
are multiple entries on the same day for the eDiary component, use the 
worst result (larger number);
iii. If there are non-missing diary data from 7 days, the subtotal score is 
calculated as the sum of the 7-day scores, and multiplying the factor for 
the corresponding component as listed in the table above;
iv. If there are non-missing diary data from less than 7 days but greater than 3 
days (4, 5, 6 days), the subtotal score is calculated as average of the 
dairy data and times 7, and multiplying the factor for the corresponding 
component as listed in the table above;
v. If there are only less than 4 days of non-missing diary data available, the 
subtotal score will be set to missing.
b. "9-2 approach"
i. Select the diary data from 9 days prior to the CDAI calculation date, and 
set the data from the 2 days (the day prior to, and on the day of the 
endoscopy date) to missing;
ii. Take non-missing diary data from 7 most recent days from step i. If there 
are multiple entries on the same day for the eDiary component, use the 
worst result (larger number);


Upadacitinib (ABT-494)
M14-433 – Statistical Analysis Plan
Version 4.0 – 22 January 2022
71
iii. If there are non-missing diary data from 7 days, the subtotal score is 
calculated as the sum of the 7-day scores, and multiplying the factor for 
the corresponding component as listed in the table above;
iv. If there are non-missing diary data from less than 7 days but greater than 3 
days (4, 5, 6 days) OR from 3 consecutive days, the subtotal score is 
calculated as average of the dairy data and times 7, and multiplying the 
factor for the corresponding component as listed in the table above;
v. If there are non-missing diary data from 3 non-consecutive days OR less 
than 3 days of non-missing diary data available, the subtotal score will 
be set to missing.
c.
Average daily SF/AP will be determined in the same way as described above to 
derive PROs-related endpoints (for example, clinical remission per PROs); 
d. The "14-4 approach" will be used to calculated CDAI, average daily SF/AP at 
each CDAI date.  Sensitivity analyses which are based on "9-2 approach" to 
calculate CDAI and SF/AP will be performed on primary endpoints (Clinical 
Remission per CDAI at Week 12, Clinical Remission per PROs at Week 12).
3.
Subtotal scores for components 4-6 (Number of 6 listed categories, usage of 
Lomotil/Imodium/Loperamide/opiates for diarrhea and abdominal mass) will be 
determined using the data collected on the CDAI calculation date and the 
corresponding formula in the table above;
4.
Subtotal score for component 7 (Hematocrit) is calculated as follows:
a.
Identify the Hematocrit (%) value form the same visit as the CDAI calculation 
date, use the Hematocrit that is closest to the CDAI calculation date;
b. Hematocrit values obtained from previous visits can be used.
c.
The subtotal score for Hematocrit is calculated using the formula in the table 
above.  If Hematocrit value is greater or equal to 47% for male subjects (greater 
or equal to 42% for female subjects), the subtotal score is set to 0.

5.
Subtotal score for component 8 (percentage below standard weight) is calculated as 
follows:
a.
Standard weight is calculated based on height obtained at screening, sex and 
study protocol Appendix H;
b. Body weight is based on the measurement obtained on the CDAI calculation 
data, or previous visits if the measurement is missing.
c.
The subtotal score for percentage below standard weight is calculated using the 
formula in the table above. 
6.
CDAI score is calculated as the sum of subtotal scores of 8 components, and the 
total CDAI score will be rounded to 1 decimal.  If any of the subtotal scores are 
missing, the CDAI score will be missing.

Patient Reported Outcomes Questionnaires Descriptions
IBDQ – Inflammatory Bowel Disease Questionnaire
The IBDQ is a 32-item (ranges 1 – 7) self-report questionnaire for patients with IBD to 
evaluate the patient reported outcomes across 4 dimensions:  bowel symptoms (loose 
stools, abdominal pain), systemic symptoms (fatigue, altered sleep pattern), social 
function (work attendance, need to cancel social events), and emotional function (anger, 
depression, irritability).  The IBDQ total Score ranges from 32 to 224 with a higher score 
indicating better outcome.  
The derivation of the IBDQ total score and the four IBDQ domain scores are as follows:


Upadacitinib (ABT-494)
M14-433 – Statistical Analysis Plan
Version 4.0 – 22 January 2022
76
Domain Scores:
S1.
BOWEL SYMPTOM: Q1 + Q5 + Q9 + Q13 + Q17 + Q20 + Q22 + Q24 + Q26 + 
Q29
[score ranges from 10 - 70],
S2.
SOCIAL FUNCTION: Q4 + Q8 + Q12 + Q16 + Q28
[score ranges from 5 - 35],
S3.
SYSTEMIC SYMPTOM: Q2 + Q6 + Q10 + Q14 + Q18
[score ranges from 5 - 35],
S4.
EMOTIONAL FUNCTION: Q3 + Q7 + Q11 + Q15 + Q19 + Q21 + Q23 + Q25 + 
Q27 + Q30 + Q31 + Q32
[score ranges from 12 - 84].
Total Score:
IBDQ Total Score = SUM of (bowel symptom domain score, social function domain 
score, systemic symptom domain score, emotional function domain score).
The following convention applies to IBDQ:
When not more than 20% of items in a domain of IBDQ were missing, it was substituted 
with the mean values from the items completed in the particular domain; otherwise, they 
were treated as missing.  The 20% threshold in each domain is:  bowel symptom domain:  
2 items, systemic symptom domain:  1 item, social function domain:  1 item, emotional 
function domain:  2 items.  If any of the 4 domain scores is missing, the total IBDQ score 
will be set to missing.
WPAI-CD – Work Productivity and Activity Impairment Questionnaire-Crohn's 
Disease
The WPAI assesses the impact of the condition on work productivity losses and 
impairment in daily activity.  WPAI has six items covering four domains:  Absenteeism 
(work time missed), measured as the number of hours missed from work in the past 7 


Upadacitinib (ABT-494)
M14-433 – Statistical Analysis Plan
Version 4.0 – 22 January 2022
77
days due to a condition related problem.  Scores are expressed as impairment percentages, 
adjusting for hours actually worked according to the WPAI scoring algorithm; 
Presenteeism (impairment at work/reduced on-the-job effectiveness), measured as the 
impact of the condition on productivity while at work (i.e., reduced amount or kind of 
work, or not as focused as usual).  Responses are recorded on a 0 – 10 Likert scale (where, 
0 = no effect of CD on work and 10 = severe impact of CD while at work); productivity 
loss (overall work impairment), measured as the sum of hours missed due to condition 
i.e., absenteeism and number of hours worked with impairment i.e., product of number of 
hours worked and presenteeism; and activity impairment (i.e., activities other than paid 
work like work around house, cleaning, shopping, traveling, studying), recorded and 
scored in same way as presenteeism.  Higher numbers indicate greater impairment and 
less productivity.  
CSS – Crohn's Symptoms Severity Questionnaire
The CSS questionnaire is a 14-item assessment of both GI and non-GI CD symptoms 
using a 7-day recall period.  The 14 items assess the frequency or intensity of each 
individual symptom by utilizing a 5-point Likert-type scale.  An assessment of an 
individual items frequency and intensity is measured as follows: 
●
Frequency:  1 = Never, 2 = Rarely, 3 = Sometimes; 4 = Often, 5 = Always
●
Intensity:  1 = Not at all, 2 = A little bit; 3 = Somewhat; 4 = Quite a bit; 
5 = Very much
An overall symptom score is calculated by combining ratings from the 14 individual items 
(possible scores range from 14 to 70) with higher scores indicating greater symptom 
frequency or intensity.  
SF-36 – Short Form 36
The SF-36 questionnaire is a self-administered multi-domain scale with 36 items.  
Eight subscales cover a range of functioning:  physical functioning, role-physical, bodily 


Upadacitinib (ABT-494)
M14-433 – Statistical Analysis Plan
Version 4.0 – 22 January 2022
78
pain, general health, vitality, social functioning, role-emotional, and mental health.  The 
scoring yields a physical component score, a mental component summary score, and 
subscale scores.  Higher scores represent better outcomes.  The concepts measured by the 
SF-36 are not specific to any age, disease, or treatment group, allowing comparison of 
relative burden of different diseases and the benefit of different treatments.  
EQ-5D – European Quality of Life 5 Dimensions
The EQ-5D-5L is a standardized non-disease specific instrument for describing and 
valuing health-related quality of life.  The EQ-5D consists of 5 dimensions:  mobility, 
self-care, usual activity, pain/discomfort, and anxiety/depression.  Each dimension has 
5 levels:  no problem, slight problem, moderate problem, severe problem or unable to do 
the activity.  It also contains a Visual Analogue Scale (VAS).  Subjects are asked to 
indicate the level that describes their current level of function or experience for each 
dimension.  As a measure of health status, it provides a descriptive profile and can be used 
to generate a single index value for health status, where full health is equal to 1 and death 
is equal to 0.  The VAS records the subject's assessment of his/her own health along a 
vertical 20 cm line, which has health state scores between 0 and 100.  
FACIT-F – Functional Assessment of Chronic Illness Therapy-Fatigue
The Functional Assessment of Chronic Illness Therapy (FACIT) measurement system is a 
comprehensive compilation of questions that measure health related quality of life in 
patients with cancer and other chronic diseases (www.facit.org).  The FACIT-F scale is a 
symptom-specific subscale of FACIT and is composed of 13 fatigue-related questions as 
follows.  The response to each question is as follows: 0=Not at all, 1=A little bit, 
2=Somewhat, 3=Quite a bit, 4=Very much.
1.
I feel fatigued
2.
I feel weak all over
3.
I feel listless ("washed out")

I am too tired to eat
11.
I need help doing my usual activities
12.
I am frustrated by being too tired to do the things I want to do
13.
I have to limit my social activity because I am tired
In order to have higher values representing lower level of fatigue, all of the items, except 
for item 7 "I have energy" and item 8 "I am able to do my usual activities," are assigned 
reversed scores: reversed score = 4 – raw score.  The total FACIT-F score will then be 
calculated as follows: 
●
FACIT-F score = 13[Sum of answered-item scores / Number of items 
answered]
The score ranges from 0 to 52, 52 being the lowest level of fatigue.  
When there are missing data, provided that more than 50% of the items (i.e., at least 7 of 
13 items) were answered in FACIT-F questionnaire, the total score will not be deemed as 
missing but be calculated as the mean response for all the non-missing-value items.  If 
less than 50% of the items were answered, the total score will have a missing value.

Synopsis
AbbVie Inc.
Protocol Number:  M14-433
Name of Study Drug:  Upadacitinib (ABT-494)
Phase of Development:  3
Name of Active Ingredient:
Upadacitinib (ABT-494) 
Date of Protocol Synopsis: 24 September 2020
Protocol Title:  A Multicenter, Randomized, Double-Blind, Placebo-Controlled Induction Study of the 
Efficacy and Safety of Upadacitinib (ABT-494) in Subjects with Moderately to Severely Active Crohn's 
Disease Who Have Inadequately Responded to or are Intolerant to Conventional and/or Biologic 
Therapies 
Objective:  The objective of Study M14-433 is to evaluate the efficacy and safety of upadacitinib 
compared to placebo as induction therapy in subjects with moderately and severely active Crohn's 
disease (CD).
Investigators:  Multicenter
Study Sites:  Approximately 400 sites worldwide.
Study Population:  Males and females between 18 and 75 years of age (or minimum age of adult 
consent according to local regulations) with a confirmed diagnosis of CD for at least 3 months and 
moderately to severely active CD.
Moderately to severely active CD is defined by:

Average daily very soft or liquid stool frequency (SF) ≥ 4 AND/OR average daily abdominal pain 
(AP) score ≥ 2 (values represent the unweighted daily averages of the corresponding subscores 
from the Crohn's Disease Activity Index [CDAI]); and

Evidence of mucosal inflammation, defined as Simplified Endoscopic Score for CD (SES-CD) ≥ 6 
(≥ 4 for subjects with isolated ileal disease), excluding the presence of narrowing component.
The study will enroll approximately 501 subjects, who have had inadequate response or intolerance to 
conventional therapies but have not failed biologic therapy (non-bio-IR population) and/or one or more 
biologic agents for CD (bio-IR population).
Conventional therapy is defined as one or more of the following:  oral locally acting steroids (e.g., 
budesonide, beclomethasone), systemic corticosteroids (prednisone or equivalent), or 
immunosuppressives (e.g., azathioprine [AZA], 6-mercaptopurine [6-MP], methotrexate [MTX]).  
Subjects who have used biologics for up to 1 year and have discontinued for reasons other than 
inadequate response or intolerance (e.g., change of insurance/reimbursement, well-controlled disease, 
etc.) may be enrolled but must meet the criteria for intolerance or inadequate response to oral locally 
acting steroids, systemic steroids, and/or immunosuppressives.  Within the non-bio-IR subjects enrolled, 
the study will allow for enrollment of approximately 20% of subjects who could also had previous use of 
biologic therapies but discontinued based on reasons other than inadequate response or intolerance.
The biologics approved for the treatment of CD include adalimumab, certolizumab, infliximab, 
ustekinumab, and/or vedolizumab.  Within the bio-IR subjects, the study will allow enrollment of 
approximately 30% subjects who have failed 3 or more biologics.  
Number of Subjects to be Enrolled:  Approximately 501 subjects worldwide.

Methodology:  
Study M14-433 is a Phase 3, randomized, double-blind, placebo-controlled induction study to evaluate 
the efficacy and safety of upadacitinib, an orally administered Janus kinase 1 inhibitor, in adult subjects 
with moderately to severely active CD.
Subjects who consent and meet all of the inclusion criteria and none of the exclusion criteria will be 
enrolled into this study, which encompasses 2 parts:  (Part 1) a randomized, double-blind, placebo-
controlled induction; and (Part 2) an Extended Treatment Period for non-responders from Part 1.
Study visits may be impacted due to the COVID-19 pandemic or any state of emergency or pandemic 
situation.  If visits cannot be conducted onsite due to travel restrictions or other pandemic-related 
reasons, phone or virtual visits, visits at alternative locations, or changes in the visit frequency and 
timing of study procedures, among others may be performed.  Additional details are provided in the 
subsequent sections.  Every effort should be made to ensure the safety of subjects and site staff, while 
maintaining the integrity of the study.
Part 1
In Part 1, subjects (n = 501) will be randomized in a 2:1 ratio to upadacitinib 45 mg once daily (QD) or 
matching placebo for 12 weeks.  The randomization will be stratified by baseline corticosteroid use (yes 
or no), endoscopic disease severity (SES-CD < 15 and ≥ 15) and number of prior biologics with prior 
inadequate response or intolerance (0, 1, > 1).  The data collected from subjects from Part 1 will be used 
for the primary efficacy analysis.
Visits during the study will occur at Baseline and Weeks 2, 4, 8, and 12/Premature Discontinuation (PD) 
to collect clinical, endoscopic and laboratory assessments of disease activity.
At Week 12, subjects achieving clinical response, defined as ≥ 30% decrease in average daily very soft 
or liquid SF and/or ≥ 30% decrease in average daily AP score (both not worse than Baseline) may be 
eligible to enter the 52-week, double-blind, maintenance portion of Study M14-430.
All subjects who do not achieve clinical response at Week 12 will be eligible to participate in Part 2 
(Extended Treatment Period) to receive double-blind upadacitinib until Week 24/PD.
Subjects are not eligible to enter Study M14-430 until the ileocolonoscopy procedure at Week 12 has 
been completed.  If the COVID-19 pandemic precludes a subject from undergoing an endoscopy, the 
subject can enroll in Study M14-430 if clinical response was achieved at Week 12.  
Part 2
Part 2 is a 12-week Extended Treatment Period consisting of 2 cohorts of subjects who did not achieve 
clinical response at Week 12 in Part 1.  The objectives of Part 2 are to offer blinded upadacitinib 
induction treatment to placebo non-responders from Part 1, and to evaluate delayed clinical response to 
upadacitinib in subjects who did not initially respond to upadacitinib during Part 1.
Cohort 1:  Subjects who received placebo during Part 1 and did not achieve clinical response at 
Week 12 are eligible to receive double-blind, induction treatment with upadacitinib 45 mg QD for 
12 weeks (until Week 24).
Cohort 2:  Subjects who received upadacitinib during Part 1 and did not achieve clinical response at 
Week 12 are eligible to receive double-blind upadacitinib 30 mg QD for 12 weeks (until Week 24).

Methodology (Continued):
Part 2 (Continued)
Subjects in Part 2 will remain blinded to treatment to avoid unmasking the treatment received during 
Part 1.  The data collected from subjects from Part 2 will not be part of the primary efficacy analysis for 
this study, will use descriptive statistics, and will be reported separately in the clinical study report.
Subjects are not eligible to enter in Part 2 until the Week 12 endoscopy has been completed.  Visits will 
occur at Weeks 16, 20 and 24/ PD to collect clinical, endoscopic, and laboratory assessments of disease 
activity.
During Part 2, subjects with persistent symptoms or worsening of CD may be discontinued at any time.
At Week 24, subjects who achieve clinical response may be eligible to enter Study M14-430.
Subjects are not eligible to enter Study M14-430 until the ileocolonoscopy procedure at Week 24 for 
evaluation of mucosal inflammation has been completed.  If the COVID-19 pandemic precludes a 
subject from undergoing an endoscopy, the subject can enroll in Study M14-430 if clinical response was 
achieved at Week 24.  
Subjects who do not achieve clinical response at Week 24 will be discontinued from Study M14-433 and 
will receive standard of care treatment at the investigator's discretion.  Subjects who do not achieve 
clinical response at Week 24 and all subjects who prematurely discontinue the study will have a 
follow-up visit 30 days from the last dose of study drug to collect information on new or ongoing 
adverse events (AEs) and laboratory assessments.  Subjects will be discontinued from the study if they 
withdraw consent or if they are deemed unsuitable to continue for any reason by the investigator.
The duration of the study could be up to 33 weeks, including Screening Period (5 weeks), a 12 week 
double-blind Induction Period (Part 1), a 12-week Extended Treatment period (Part 2) and a 30-day 
follow-up visit for subjects who do not enroll into the maintenance Study M14-430.
At the Screening Visit, all subjects will be provided with an electronic diary.  Subjects will be instructed 
and trained on how to record CD-related symptoms (including total and very soft and liquid number of 
stools and abdominal pain), general well-being and use of anti-diarrheals on a daily basis; and use of 
medications for endoscopy preparation throughout the study.  The very soft and liquid stools are defined 
as consistency Type 6 or Type 7 based on the Bristol Stool Chart.
The diary will be reviewed by site personnel with the subject at each visit and for the assessment of the 
clinical endpoints.  SF and AP entries from the most recent 7-day period prior to each study visit will be 
used.  At each Study Visit, routine physical examination including evaluation of vital signs, extra 
intestinal manifestations, and presence or absence of fistulas; calculation of CDAI score, average daily 
very soft or liquid SF and average daily AP score; monitoring of AEs; reporting of concomitant 
medications and laboratory assessments will be performed.  The very soft or liquid SF values represent 
the unweighted daily averages of the corresponding subscores from the CDAI.  Additionally, subjects 
will complete quality of life (QoL), CD symptoms and symptoms impact on QoL, and work productivity 
questionnaires throughout the study.
Subjects will undergo a full colonoscopy (ileocolonoscopy) for evaluation of mucosal inflammation 
using the SES-CD.  All endoscopies will be centrally read to document eligibility at Screening, and for 
Week 12 and 24/PD assessments.  Intestinal biopsies during the endoscopic evaluation will be collected 
for histologic assessment and exploratory research during endoscopy visits at Screening, Week 12 and 
Week 24/PD in approximately 200 subjects (intestinal biopsy substudy).

Methodology (Continued):
Part 2 (Continued)
Optional blood samples will be collected for exploratory research at Baseline, Week 4, Week 12 and 
Week 24/PD.  Optional stool collections will be done at Baseline, Week 4 and Week 12 for exploratory 
evaluation of biomarkers in approximately 100 subjects (fecal biomarker substudy).
Concomitant CD-Related Medications (Antibiotics, Aminosalicylates, and/or Methotrexate)
All subjects receiving a stable dose of CD-related antibiotics, aminosalicylates, or MTX at Baseline 
should maintain their concomitant treatments without dose changes through the end of the study.  
Initiating and/or changing doses of these medications are prohibited during the study.  Doses of CD-
related antibiotics, aminosalicylates, or MTX may be decreased only in the event of safety or tolerability 
issues.
Concomitant Corticosteroids
Subjects who enter the study on oral corticosteroids are not allowed to change the corticosteroid dose 
during the first 4 weeks of the induction treatment period.  Dose may be decreased only for safety or 
tolerability issues.  Initiating locally acting (rectal or suppository) or systemic corticosteroids is 
prohibited during the induction treatment period.
At Week 4, subjects who are on prednisone (or oral equivalent) or oral budesonide must have their 
corticosteroid dose tapered, according to the tapering schedule.
Subjects who do not achieve clinical response at Week 12 and enter Part 2 without having completed the 
steroid taper should resume the corticosteroid taper at Week 16, according to the tapering schedule.

Additional pre-specified efficacy variables are outlined in the protocol.
Pharmacokinetic:  Upadacitinib plasma concentrations will be determined from samples collected at 
each visit beginning at Week 2.  Blood samples at the Week 4 visit will be collected prior to dosing if 
possible.  For all other visits, blood samples will be collected at any time during the visit.
Safety:  Safety analyses will be performed on the safety set, which includes all subjects who receive at 
least one dose of study drug.  The incidence of AEs, changes in vital signs, physical examination results, 
and clinical laboratory data will be assessed throughout the study.  AEs and laboratory data, when 
available, will be graded as described in the National Cancer Institute Common Terminology Criteria for 
Adverse Events and summarized accordingly.
An external, independent Data Monitoring Committee will be responsible for monitoring unblinded 
safety data and alerting AbbVie to possible safety concerns related to the conduct of the study.
Exploratory Research Variables (Optional Serum, Whole Blood, Stools and Biopsy Samples):  
Prognostic, surrogate, predictive, and pharmacodynamic biomarker signatures may be investigated.  
Samples for different applications including, but not limited to, pharmacogenetic, epigenetic, 
transcriptomic, proteomic, metabolomic, metagenomic, and targeted investigations will be collected at 
various time points.  Optimal serum and whole blood collections will be done at Baseline, Week 4, 
Week 12, and Week 24/PD for evaluation of biomarkers.  Optional stool collections will be done at 
Baseline, Week 4, and Week 12 for evaluation of biomarkers.  Biopsies include optional samples at 
Screening, Week 12, and Week 24/PD.  Assessments will include but may not be limited to nucleic 
acids, proteins, metabolites, or lipids.

Statistical Methods:
Efficacy:  The co-primary endpoints are the proportion of subjects with clinical remission per PROs 
(EU/EMA) or clinical remission per CDAI (US/FDA) at Week 12 and the proportion of subjects with 
endoscopic response at Week 12.  This study will evaluate one induction dose of upadacitinib 45 mg 
QD.
Efficacy analysis will be based on all intent-to-treat (ITT) subjects.  The ITT analysis set includes all 
randomized subjects who have taken at least one dose of study drug in the double-blind induction period 
from Part 1.
The comparison between treatment groups on the co-primary efficacy endpoints will be performed using 
the Cochran-Mantel-Haenszel (CMH) test and will be stratified by Baseline corticosteroid use (yes or 
no), endoscopic disease severity (SES-CD < 15 and ≥ 15) and number of prior biologics with prior 
inadequate response or intolerance (0, 1, > 1).  Both of the co-primary efficacy endpoints will be tested 
at two-sided significance level of 0.05.  A CMH-based, two-sided 95% confidence interval for the 
difference between treatment groups will be calculated.  If the average daily very soft or liquid SF or 
average daily AP score (EU/EMA) or CDAI (US/FDA) data at Week 12 are missing, the non-responder 
imputation approach will be applied for the clinical remission per PROs and clinical remission per CDAI 
endpoints, respectively.  Subjects who discontinue prior to Week 12 for any reason will be considered as 
"not-achieved" for clinical remission or endoscopic response endpoints.
A multiple testing procedure will be used to provide strong control of the type 1 error rate at 
alpha = 0.05 (2-sided) across analyses with respect to the co-primary endpoints, and ranked secondary 
endpoints. Specifically, testing will utilize a sequence of hypothesis testing for the co-primary endpoints 
followed by the ranked secondary endpoints, and will begin with testing co-primary endpoints using α of 
0.05 (2-sided). If both co-primary endpoints achieve statistical significance, continued testing will 
follow a pre-specified weight of α allocation between individual hypotheses as well as between families 
of hypotheses.  The details of the testing procedure will be specified and documented in the statistical 
analysis plan (SAP).
In general, continuous secondary efficacy variables with repeated measurements will be analyzed using a 
Mixed Effect Repeated Measure (MMRM) model. Continuous secondary efficacy variables which are 
collected at only one post-baseline visit (such as SES-CD) will be analyzed using an Analysis of 
Covariance (ANCOVA) model. Categorical secondary efficacy variables will be analyzed using the 
CMH test controlling for stratification variables. NRI for missing data will be used for categorical 
secondary endpoints.
Pharmacokinetic:  A non-linear mixed-effects modeling approach will be used to estimate the 
population central values and the empirical Bayesian estimates of the individual values for upadacitinib 
oral clearance and volume of distribution.  Additional parameters may be estimated if useful in the 
interpretation of the data.  Data from this study may be combined with data from other studies for the 
population pharmacokinetic analyses.

Statistical Methods (Continued):
Safety:  AEs, laboratory data, and vital signs are the primary safety parameters in this study.  All safety 
comparisons will be performed between treatment groups using the safety set.  Treatment-emergent AEs 
are defined as events that begin or worsen either on or after the first dose of the study drug and within 
30 days after the last dose of the study drug for subjects who do not participate in Study M14-430, or 
within 30 days after the last dose of study drug in Study M14-433 or first dose of study drug in 
Study M14-430, if the subject enrolls in Study M14-430, whichever comes first.
An overview of treatment-emergent AEs, including AEs of special interest, AEs leading to death, AEs 
leading to PD, AEs by Medical Dictionary for Drug Regulatory Activities preferred term and system 
organ class, AEs by maximum relationship to study drug, and AEs by maximum severity will be 
summarized by number and percentage.
Changes in laboratory data will be described using statistical characteristics and comparison between-
treatment groups will be performed using a one-way Analysis of Variance.  In addition, shift tables and 
listings will be provided for abnormal values, whereby the normal range of the analyzing laboratory will 
be used.  Vital signs will be analyzed similarly.

Introduction
Crohn's disease (CD) encompasses a spectrum of clinical and pathological processes 
manifested by focal asymmetric, transmural, and occasionally granulomatous 
inflammation that can affect any segment of the gastrointestinal tract.1  The disease can 
affect persons of any age, and its onset is most common in the second and third decades.  
Females are affected slightly more than males, and the risk for disease is higher in some 
ethnic groups.2,3  In North America, the incidence of CD is estimated to be 3.1 to 
14.6 cases per 100,000 persons.  Prevalence rates range from 26 to 99 cases per 
100,000 persons.  In Europe, CD has an incidence of 0.7 to 9.8 cases per 100,000 persons 
and a prevalence rate of 8.3 to 214 cases per 100,000 persons.2
CD has been characterized by significant morbidity including abdominal pain, diarrhea, 
weight loss/malnutrition, a progressive nature that leads to complications such as fistulas, 
strictures and abscesses.
Given that no known medical or surgical cure currently exists for CD, the therapeutic 
strategy is to reduce symptoms, improve quality of life (QoL), reduce endoscopic 
evidence of inflammation, and minimize short- and long-term toxicity and complications.3  
Currently, patients with moderate to severe disease who have failed aminosalicylates or 
topical treatments are usually treated with conventional pharmacologic interventions, 
which include corticosteroids and immunosuppressive agents such as azathioprine (AZA), 
6-mercaptopurine (6-MP), or methotrexate (MTX).1,4  Local or systemic corticosteroids 
may be used for induction of remission, but are not recommended as maintenance therapy, 
due to their side effect profile.5,6  Immunosuppressants are recommended for use as 
maintenance therapy; however, not all patients have a clinically meaningful response or a 
sustained response to these therapies.  Patients who do not respond to conventional 
therapies may be treated with biologics, such as anti-tumor necrosis factor (TNF) α 
therapies.1,4  However, approximately 40% of patients do not respond to their 
first biologic therapy (primary non-responders).7-11  Among patients who initially respond 
and continue to receive maintenance treatment for longer durations, approximately 38%

30
become non-responders after 6 months and approximately 50% become non-responders at 
1 year (secondary non-responders).8,10  Patients who initially respond to a first anti-TNF 
agent but then lose response tend to have lower response and remission rates to the second
anti-TNF agent or other biologic therapies.10,12  Vedolizumab, an anti-integrin biologic, is 
associated with a relatively slower onset of action and the majority of subjects in the 
Phase 3 clinical induction (85%) and maintenance (68.6%) trials did not achieve 
remission.  Furthermore, vedolizumab treatment has not been associated with reduction of 
systemic signs of inflammation (such as C-reactive protein [CRP]).13  More recently, 
ustekinumab, which targets the p40 subunit shared by interleukin (IL)-23 and IL-12, 
demonstrated efficacy in three Phase 3 studies (UNITI-1, UNITI-2,14 and IM-UNITI15) in 
subjects with CD.  In UNITI-1 and UNITI-2, clinical remission rates at Week 8 were 
20.9% and 40.2%, respectively, compared with placebo (7.3% and 19.6%, respectively).  
After maintenance treatment, 53.1% of patients receiving ustekinumab achieved clinical 
remission, versus 35.9% of patients receiving placebo at Week 44.  The available 
treatment options may also be associated with some adverse events (AEs) that may limit 
the use or require close monitoring.  Therefore, there remains a medical need for 
additional therapeutic options in CD for patients with inadequate response to or 
intolerance to conventional therapies and anti-TNF α agents.
Rationale for Development of a JAK Inhibitor in CD
Inhibition of Janus kinase (JAK)-mediated pathways is a promising approach for the 
treatment of patients with CD.16  The JAK family is composed of 4 family members:  
JAK1, 2, 3, and Tyrosine kinase 2.  These cytoplasmic kinases are associated with 
membrane cytokine receptors such as common gamma-chain (CGC) receptors and the 
glycoprotein 130 (gp130) transmembrane proteins.17  Activation of JAK pathways 
initiates expression of survival factors, cytokines, chemokines, and other molecules that 
facilitate leukocyte cellular trafficking and cell proliferation which contribute to 
inflammatory and autoimmune disorders.18
In CD, the imbalance between anti-inflammatory and pro-inflammatory cytokines in the 
mucosal immune system is thought to play an important role.  Cells from the innate

31
mucosal immune system, i.e., TH1 or TH17, are over-activated and secrete various pro-
inflammatory cytokines such as interferon gamma (INF-g), TNFα, IL-6, IL-1b, IL-12, 
IL-23.  These cytokines signal via JAK pathways.19
JAK3 and JAK1 are components of the CGC cytokine receptor complexes and blockade 
of either inhibits signaling by the inflammatory cytokines IL-2, -4, -7, -9, -15 and -21.20
Cytokines such as IL-6 bind to gp130 and transduce its signal predominantly via JAK1.21  
Targeting the IL-6 receptor (IL-6R) is a promising approach given the fact that expression 
of IL-6 and soluble IL-6 receptors is elevated in patients with active CD.22  Thus, 
inhibition of JAK1 is expected to attenuate the signaling of IL-6 and other pro-
inflammatory cytokines (i.e., IFN-g), that are involved in development of CD.
Tofacitinib, a pan-JAK inhibitor approved for use in rheumatoid arthritis (RA), failed to 
demonstrate the efficacy in two Phase 2 studies in CD.23  Filgotinib, a second generation 
JAK inhibitor, selective for JAK1, induced clinical remission in significantly more 
patients with active CD compared with placebo, however, did not demonstrate endoscopic 
improvement after a 10-week induction period.24
JAK inhibitors have been associated with infections, including herpes zoster reactivation, 
malignancies, and asymptomatic, mild and reversible changes in levels of hemoglobin, 
lymphocyte counts, white blood cell (WBC) counts, serum creatinine, total cholesterol, 
high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol 
(LDL-C) and liver transaminases (alanine transaminase [ALT], aspartate transaminase 
[AST]) and creatine phosphokinase (CPK).24,25
Upadacitinib is a novel selective JAK1 inhibitor being developed for the treatment of 
adult patients with CD.  In an in vitro setting, upadacitinib potently inhibits JAK1 activity, 
but to a lesser degree, inhibits the other isoforms, JAK2 and JAK3.  The enhanced 
selectivity of upadacitinib against JAK1 may offer an improved benefit-risk profile in 
patients with CD.  The clinical hypothesis is that upadacitinib should be effective in 
decreasing inflammation and damage associated with CD by interfering with 
JAK1-mediated signaling pathways (i.e., IL-6) without causing excessive anemia due to

M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
32
its reduced activity against JAK2 (half maximal inhibitory concentration [IC50] 120 nM), 
which is essential for erythropoietin signaling.  Upadacitinib is also less potent against 
JAK3 (IC50 2.3 µM), an important component of lymphocyte activation and function.  As 
such, treatment with upadacitinib, a selective JAK1 inhibitor with reduced JAK3 
inhibition, could result in a decreased risk for infection (including viral reactivation) 
and/or malignancy compared to less selective JAK inhibitors.
Additional information regarding the preclinical toxicology, metabolism, pharmacology, 
safety experience and indications under study with upadacitinib can be found in the 
current edition of the Investigator's Brochure.26
Upadacitinib has been evaluated in Phase 2 dose ranging placebo-controlled studies in 
subjects with moderately to severely active CD (Study M13-740; NCT02365649), and 
moderately to severely active RA (Study M13-537; NCT02066389 and Study M13-550; 
NCT01960855).  The 52-week data in subjects with CD from Study M13-740 suggest that 
upadacitinib may alleviate signs and symptoms of active CD and reduce mucosal 
inflammation.
In Study M13-740, 220 subjects were randomized to 4 twice daily (BID), 1 once daily 
(QD) dose regimens of upadacitinib immediate release capsules (3 mg BID, 6 mg BID, 
12 mg BID, 24 mg BID, and 24 mg QD) or placebo.  As induction treatment, a 
statistically significant dose-response relationship was observed with upadacitinib for the 
co-primary endpoint of endoscopic remission.  A dose-response was not observed for the 
clinical remission co-primary endpoint; however, a new endpoint for potential use as 
primary in Phase 3 demonstrated a statistically significant dose-response relationship for 
clinical remission in the 6 mg BID and 24 mg BID dose groups compared to placebo.  
Endoscopic response was statistically significantly better in all upadacitinib dose groups 
except for 3 mg BID compared to placebo.  In the Extension Phase, subjects who achieved 
response and were re-randomized to the 12 mg BID group achieved statistically 
significant clinical remission and endoscopic outcomes compared to subjects in the 3 mg 
BID group at Week 52.

33
Safety data from the induction portion of Study M13-740 were consistent with the profile 
observed in the Phase 3 RA studies.  The incidences of AEs in Study M13-740 were 
numerically higher in the upadacitinib dose groups, with no dose relationship.  Infections 
occurred with higher incidences in the upadacitinib groups than the placebo group, but 
also did not show dose-related increases.  The most frequently reported AEs (≥ 5%) in the 
upadacitinib treated subjects were headache, Crohn's disease, abdominal pain, fatigue, 
nasopharyngitis, urinary tract infection, upper respiratory tract infection, vomiting and 
pyrexia.  Upadacitinib continued to be generally well tolerated following re-
randomization of subjects at Week 16 to upadacitinib 3 mg BID, 6 mg BID, 12 mg BID, 
or 24 mg QD through Week 52 of the Extension Phase. There were 5 subjects with non-
serious events of herpes zoster reactivation.  Two events of gastrointestinal perforation 
were reported in 2 subjects; 1 subject had worsening of CD and associated fistulization 
and abscess, and the other subject had a perforation in an area of fissuring ulcer.  Similar 
to the RA Phase 3 studies, increase in LDL-C and HDL-C, reductions in natural killer 
(NK) cells, slight decreases in red blood cell (RBC) counts, and asymptomatic and 
transient CPK elevations were observed.  No deaths were reported during the study.
All subjects who complete Study M13-740 are eligible to enroll in Study M14-327, a 
Phase 2, open-label extension study to evaluate the long-term safety and efficacy of 
upadacitinib.
Study M14-433 will evaluate one induction dose of upadacitinib (45 mg QD) of the once-
daily modified-release tablet formulation.  The selection of this dose was informed by the 
analysis of the 16-week safety, efficacy, and exposure-response Phase 2 data from 
Study M13-740.  In addition, all the currently available pharmacokinetic (PK), 
pharmacodynamic, safety, and efficacy data from upadacitinib studies were used to 
support the selection of this dose.  Upadacitinib 45 mg QD, dosed for up to 12 weeks, is 
expected to be efficacious with an acceptable safety profile, and upadacitinib 15 mg QD 
and 30 mg QD, dosed for up to 240 weeks as maintenance treatment, are expected to be 
efficacious with acceptable safety profiles.

In this study, subjects with moderately to severely active CD will be enrolled.  Moderate 
to severe active disease will be determined by evidence of active intestinal mucosal 
inflammation assessed by the Simplified Endoscopic Score for CD (SES-CD), confirmed 
by a central endoscopy reader; and the presence of signs and symptoms of the patient-
reported outcomes and Crohn's Disease Activity Index (CDAI) subcomponents of very 
soft/liquid stool frequency and abdominal pain.  This is supported by post-hoc analyses of 
the adalimumab studies, the Phase 2 risankizumab Study 1311.6 and upadacitinib 
Study M13-740, where the proposed inclusion criterion of very soft/liquid stool frequency 
and abdominal pain score was met by 85% to 92% of subjects with baseline CDAI 220 to 
450, respectively.
3.1
Differences Statement
This study is designed to evaluate the efficacy and safety of upadacitinib 45 mg QD 
versus placebo in subjects with moderately to severely active CD.  The primary difference 
between Study M14-433 and the prior Phase 2 study of upadacitinib in CD is that this 
study will test a QD oral formulation of upadacitinib, and confirm the efficacy of 
upadacitinib in a larger CD population with inadequate response or intolerance to 
conventional and/or biologic therapies.  Additionally, some efficacy endpoint definitions 
in this study are different from Phase 2 to reflect the changing regulatory requirements for 
pivotal registrational studies for new agents for the treatment of CD.
3.2
Benefits and Risks
Although conventional and newer treatments such as biologic therapies have improved the 
standard of care for patients with CD, there remains a significant unmet medical need for 
patients with inadequate or loss of response to these agents, and efforts are ongoing to 
develop novel therapies.
Clinical efficacy in targeting pro-inflammatory cytokines and downstream signaling 
pathways has been demonstrated in CD with second generation JAK inhibitors, including 
upadacitinib.  These drugs are also being studied for the treatment of patients with 
ulcerative colitis.

Upadacitinib is a novel JAK1 selective inhibitor with minimal inhibitory effects on JAK2 
and JAK3, which could potentially minimize some of the reported safety concerns with 
pan-JAK inhibition, which are thought to be mediated by inhibition of JAK2 and JAK3 
signaling pathways.  
Adverse events (AEs) such as infections, herpes zoster reactivation, malignancies, and 
hematologic AEs have been observed with JAK inhibition.  By its selectivity for JAK1, 
upadacitinib may be able to decrease inflammation mediated by JAK1 signaling while 
having less inhibitory effect on JAK2 and JAK3.  This could potentially minimize some 
of the reported safety concerns with less selective JAK inhibition which are thought to be 
mediated by inhibition of JAK2 and JAK3 signaling pathways.
The available long-term safety data from the Phase 3 rheumatoid arthritis (RA) studies 
with upadacitinib did not show any new significant safety concerns compared to the 
marketed JAK inhibitors.  The findings of an increased risk of infections, herpes zoster, 
and abnormal laboratory changes have been observed (e.g., elevations of serum 
transaminases, lipids, creatine phosphokinase, and reductions in hemoglobin and white 
blood cells) with upadacitinib therapy.  The incidence rates of other clinically important 
adverse events 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.  Events of deep vein 
thrombosis (DVT) and pulmonary embolism (PE) have been reported in patients receiving 
JAK inhibitors including upadacitinib. In addition, no new safety signals have been 
identified in the Phase 2 (Study M13-740; NCT02365649) study of moderately to 
severely active CD with upadacitinib during 52 weeks of treatment.
The results of genetic toxicology testing indicate that upadacitinib is not genotoxic; 
however, upadacitinib is teratogenic based on animal studies, which necessitates 
avoidance of pregnancy in females of childbearing potential.  Based on the calculated 
safety margins for human fetal exposure with seminal fluid transfer, there is judged to be 
no risk to the pregnancy of female partners of male subjects who are treated with 
upadacitinib.

A detailed discussion of the pre-clinical and clinical toxicology, metabolism, 
pharmacology, and safety experience with upadacitinib can be found in the current 
Investigator's Brochure.
Taken together, the safety and efficacy data from upadacitinib studies to date show a 
favorable benefit:risk profile for upadacitinib and support the continued investigation of 
upadacitinib in patients with various autoimmune/inflammatory conditions.
AbbVie is conducting a Phase 3 study in subjects with CD based on the following 
supportive findings:  1) demonstrated clinical and endoscopic improvements in the 
induction treatment in a Phase 2 dose-ranging study; and 2) safety results were consistent 
with those known to be associated with JAK inhibition.  The current Phase 3 
Study M14-433 will further evaluate the benefit to risk profile of upadacitinib in CD 
subjects who have inadequately responded or are intolerant to conventional and/or 
biologic therapies.
In view of the coronavirus (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.

Investigational Plan
5.1
Overall Study Design and Plan:  Description
Study M14-433 is a Phase 3, randomized, double-blind, placebo-controlled induction 
study to evaluate the efficacy and safety of upadacitinib, an orally administered JAK1 
inhibitor in adult subjects with moderately to severely active CD who have inadequately 
responded to or are intolerant to conventional and/or biologic therapies.  
 


Upadacitinib (ABT-494)

37
The study will enroll approximately 501 subjects at approximately 400 study centers 
worldwide to meet scientific and regulatory objectives without enrolling an undue number 
of subjects in alignment with ethical considerations.  
Study M14-433 will enroll subjects who have had an inadequate response or intolerance 
to conventional therapies but have not failed biologic therapy (non-bio-IR population) and 
subjects who had an inadequate response or intolerance to one or more biologic agents for 
CD (bio-IR population).
Conventional therapy is defined as one or more of the following:  oral locally-acting 
steroids (e.g., budesonide, beclomethasone), systemic corticosteroids (prednisone or 
equivalent), or immunosuppressives (e.g., azathioprine [AZA], 6 mercaptopurine [6-MP], 
methotrexate [MTX]).  Among subjects who failed conventional therapy, the study will 
allow the enrollment of approximately 20% of subjects who have used biologics for up to 
1 year and have discontinued for reasons other than inadequate response or intolerance 
(e.g., change of insurance/reimbursement, well-controlled disease, etc.).  
The biologics approved for the treatment of CD include adalimumab, certolizumab, 
infliximab, ustekinumab and/or vedolizumab.  Within the bio-IR subjects, the study will 
allow enrollment of approximately 30% subjects who have failed 3 or more biologics.  
The study will allow the enrollment of up to 10% of subjects who received a JAK 
inhibitor prior to study entry if they have not had inadequate response or loss of response.
This study will evaluate one induction dose of upadacitinib (45 mg QD) (Figure 1).
Subjects who consent and meet all of the inclusion criteria and none of the exclusion 
criteria will be enrolled into this study which encompasses two parts: 
●
Part 1:  a randomized double-blind placebo-controlled induction period and 
●
Part 2:  an Extended Treatment Period for non-responders from Part 1.

Part 1
In Part 1, subjects (n = 501) will be randomized in a 2:1 ratio to upadacitinib 45 mg QD or 
matching placebo for 12 weeks (Figure 1).  The randomization will be stratified by 
baseline corticosteroid use (yes or no), endoscopic disease severity (SES-CD < 15 and 
≥15) and number of prior biologics with prior inadequate response or intolerance (0, 1, 
> 1).  The data collected from subjects from Part 1 will be used for the primary efficacy 
analysis.
Visits during the study will occur at Baseline and Weeks 2, 4, 8, and 12/Premature 
Discontinuation (PD) to collect clinical, endoscopic and laboratory assessments of disease 
activity.
At Week 12, subjects achieving clinical response, defined as ≥ 30% decrease in average 
daily very soft or liquid stool frequency (SF) and/or ≥ 30% decrease in average daily 
abdominal pain (AP) score (both not worse than Baseline) may be eligible to the 52-week, 
double-blind, maintenance portion of Study M14-430.
All subjects who do not achieve clinical response at Week 12 will be able to enroll in 
Part 2 to receive a double-blind Extended Treatment Period (Part 2) with upadacitinib 
until Week 24/PD.
Subjects are not eligible to enter Study M14-430 until the ileocolonoscopy procedure at 
Week 12 has been completed.  If the COVID-19 pandemic precludes a subject from 
undergoing an endoscopy, the subject can enroll in Study M14-430 if clinical response 
was achieved at Week 12.
 




Upadacitinib (ABT-494)

40
Subjects in Part 2 will remain blinded to treatment to avoid unmasking the treatment 
received during Part 1.  The data collected from subjects from Part 2 will not be part of 
the primary efficacy analysis, will use descriptive statistics, and will be reported 
separately in the clinical study report.
Subjects are not eligible to enter in Part 2 until the Week 12 endoscopy has been 
completed.  Visits will occur at Weeks 16, 20 and 24/PD to collect clinical, endoscopic 
and laboratory assessments of disease activity.
During Part 2, subjects with persistent symptoms or worsening of CD may be 
discontinued at any time.
At Week 24, subjects who achieve clinical response may be eligible to enter 
Study M14-430.
Subjects are not eligible to enter Study M14-430 until the ileocolonoscopy procedure at 
Week 24 for evaluation of mucosal inflammation has been completed.  If the COVID-19 
pandemic precludes a subject from undergoing an endoscopy, a subject can enroll in 
Study M14-430.
Subjects who do not achieve clinical response at Week 24 will be discontinued from 
Study M14-433 and will receive standard of care treatment at the investigator's discretion.  
Subjects who do not achieve clinical response at Week 24 and all subjects who 
prematurely discontinue the study will have a follow-up visit 30 days from the last dose of 
study drug to collect information on new or ongoing AEs and laboratory assessments.  
Subjects will be discontinued from the study if they withdraw consent or if they are 
deemed unsuitable to continue for any reason by the investigator.
The duration of the study could be up to 33 weeks, including Screening Period (5 weeks), 
a 12-week double-blind Induction Period (Part 1), a 12-week Extended Treatment Period 
(Part 2) and a 30-day follow-up for subjects who do not enroll into Study M14-430.

At the Screening Visit, all subjects will be provided with an electronic diary.  Subjects 
will be instructed and trained on how to record CD-related symptoms (including total and 
very soft and liquid number of stools and abdominal pain), general well-being and use of 
anti-diarrheals on a daily basis; and use of medications for endoscopy preparation 
throughout the study.  The very soft and liquid stools are defined as consistency Type 6 or 
Type 7 based on the Bristol Stool Chart (Appendix F).
The diary will be reviewed by site personnel with the subject at each visit and for the 
assessment of the clinical endpoints, and the SF and AP entries from the most recent 
7-day period prior to each study visit will be used.  At each Study Visit, routine physical 
examination including evaluation of vital signs, extra-intestinal manifestations (EIMs), 
presence or absence of fistulas; calculation of CDAI score, total and average daily very 
soft or liquid SF and average daily AP (very soft or liquid SF and AP entries from the 
most recent 7-day period prior to each study visit will be used); monitoring of AEs; 
concomitant medications and laboratory assessments will be performed.  The very soft or 
liquid SF values represent the unweighted daily averages of the corresponding subscores 
from the CDAI.  Additionally, subjects will complete QoL, CD symptoms and symptoms 
on QoL impact, and work productivity questionnaires throughout the study as indicated in 
Appendix C.
Clinical samples for urinalysis, chemistry and hematology, high-sensitivity C-reactive 
protein (hs-CRP), plasma upadacitinib concentrations will be collected.  In addition, stool 
samples for calprotectin analysis will be collected and should be taken before starting 
bowel preparations for endoscopy.
Subjects will undergo a full colonoscopy (ileocolonoscopy) for evaluation of mucosal 
inflammation using the SES-CD.  All endoscopies will be centrally read to document 
eligibility at Screening, and for Week 12 and 24/PD assessments.  Biopsy to confirm 
diagnosis (during Screening) or to rule out dysplasia/malignancy may be performed 
during the same time points as the endoscopy.  Optional exploratory research samples 
may be taken during the study (see also Appendix C).

Screening Period
Within 35 days prior to the Baseline Visit, subjects will receive a full explanation of the 
study design and study procedures, provide a written informed consent, and then undergo 
the screening procedures outlined in Appendix C.  Laboratory values can be re-tested 
once during the screening period.  If the re-tested lab value(s) remain(s) exclusionary, the 
subject will be considered a screen failure.  Redrawing samples if previous samples were 
unable to be analyzed would not count as a retest since previous result was never 
obtained.
The length of time between Screening and the Baseline visit must allow time for 
endoscopy central reading and laboratory results.  The Screening period will be a 
minimum of 8 days.
Subjects who have been taking exclusionary medications prior to Screening or Baseline 
must complete the medication(s) washout within the duration described in the protocol
Exclusion Criteria Section 5.2.2 prior to the Baseline Visit (i.e., 8-week washout of a 
biologic therapy).  During Screening, biologic drug levels may be optionally assessed at 
the investigator's discretion as an alternative to completing the required washout period: 
(1) infliximab and natalizumab: may be tested approximately 4 weeks from the last dose; 
(2) adalimumab, certolizumab, golimumab, or vedolizumab: may be tested approximately
6 weeks from the last dose; (3) ustekinumab: may be tested approximately 8 weeks from 
the last dose.  If the biologic drug is not detected, the subject will be considered as eligible 
and the washout period is not required.
All subjects need to have their average daily very soft or liquid SF and average daily AP 
score calculated and meeting eligibility criteria before randomization at Baseline.
Re-Screen
Subjects who initially screen fail for the study are permitted to re-screen once following 
re-consent.  For additional re-screenings, AbbVie Therapeutic Area Medical Director (TA 
MD) approval is required.  Laboratory values can be re-tested once during the 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
43
re-screening period.  As appropriate, sites are encouraged to contact the AbbVie TA MD 
to confirm if subjects should or should not be re-screened.  All screening procedures with 
the possible exceptions noted below will be repeated during re-screening.  The subject 
must meet all of the inclusion criteria and none of the exclusion criteria at the time of 
re-screening in order to qualify for the study.  There is no minimum period of time a 
subject must wait to re-screen for the study.  The re-screening period will be a minimum 
of 8 days, with the exception of subjects who are re-screened immediately after being 
screen failed and do not require a repeated endoscopy. The minimum re-screening period 
for these subjects will be 4 days.
If the subject had a complete initial screening evaluation including the assessment of an 
Interferon-Gamma Release Assay (IGRA; QuantiFERON-TB [tuberculosis] Gold In Tube 
test) and/or a purified protein derivative (PPD) test (or equivalent) (or both if required per 
local guidelines), chest x-ray and electrocardiogram (ECG), tests for hepatitis B virus 
(HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), and beta-D-
glucan (Japan only), these tests will not be required to be repeated for re-screening 
provided the conditions noted in Section 5.2 are met, there are no changes in the subject's 
medical history that would warrant re-testing, and no more than 90 days have passed since 
the collection date of the assessment. If a subject is being rescreened within 14 days 
(≤14 days have passed) from the collection date of the previous screening testing, it is not 
required to repeat Screening testing for chemistry, hematology, urinalysis, serum 
pregnancy, and Clostridium difficile provided that the subject's health status has not 
changed to warrant a repeat test.  
An endoscopy will not be required to be repeated for re-screening provided the conditions 
noted in Section 5.3.1.1 are met and no more than 45 days have passed between the 
previous screening endoscopy and Baseline.
All subjects need to have their average daily very soft or liquid SF and average daily AP 
score calculated and meeting eligibility criteria before randomization at Baseline.

12-Week Induction Period – Part 1
This period will begin at the Baseline Visit and will end at the Week 12 Visit.  At the 
Baseline Visit, subjects who meet all of the inclusion criteria and none of the exclusion 
criteria described in Section 5.2.1 and Section 5.2.2 will be enrolled into the study.  In 
Part 1, subjects will be randomized to a double-blind induction period.  All subjects will 
visit the study site at Weeks 2, 4, 8, and 12/PD, and a ± 3-day window is permitted around 
scheduled study visits.  The last dose of study drug during this period is taken the day 
prior to the Week 12 visit.
12-Week Extended Treatment Period – Part 2
This period will begin at Week 12 and will end at the Week 24 Visit.  At Week 12, 
subjects who do not achieve clinical response will enter Part 2.  Clinical response is 
defined as ≥ 30% decrease in average daily very soft or liquid SF and/or ≥ 30% decrease 
in average daily AP and both not greater than Baseline.  During this period, all subjects 
will visit the study site at Weeks 16, 20, and 24/PD.  A ± 3-day window is permitted 
around scheduled study visits.  The last dose of study drug during this period is taken the 
day prior to the Week 24 visit.
Premature Discontinuation of Study (Withdrawal of Informed Consent)
Subjects may withdraw from the study completely (withdrawal of informed consent) for 
any reason at any time (refer to Section 5.4.1 for additional details).  If a subject 
prematurely discontinues study drug treatment and study participation (withdrawal of 
informed consent), the procedures outlined for the PD visit should be completed as soon 
as possible, preferably within 2 weeks of study drug discontinuation.  In addition, if the 
subject is willing, a 30-day follow-up visit (or telephone call if a visit is not possible) 
should occur to determine the occurrence or status of any new or ongoing AEs/serious 
adverse events (SAEs).  Subjects who discontinue the study prematurely after 
randomization will not be replaced.

Discontinuation of Study Drug and Continuation of Study Participation
Subjects may discontinue study drug treatment but may choose to continue to participate 
in the study (refer to Section 5.4.1 for additional details).  Subjects who prematurely 
discontinue study drug should complete a PD visit as soon as possible, preferably within 
2 weeks.  Afterwards, subjects should follow the regular visit schedule as outlined in 
Appendix C, and adhere to all study procedures except for dispensing study drug and PK 
sample collection, and blood, stool and biopsy sample collection for optional exploratory 
research.  As the subject has discontinued study drug, all rescue and efficacy driven 
discontinuation criteria no longer apply.  If at any point a subject no longer wants to 
provide assessments (withdrawal of informed consent) following discontinuation of study 
drug, a second PD visit is not required.
Unscheduled Visits
Unscheduled Visits may occur when the subject is coming in for a medical visit for 
evaluation and assessment.  During Unscheduled Visits, blood samples will be obtained 
for the laboratory tests listed in Table 2 or for other tests at the investigator's discretion.  
Visits for dispensing new study drug in case of temperature excursion, loss or damage are 
not considered an Unscheduled Visit.  In addition, visits to only retest a lab will not be 
considered an Unscheduled Visit.
Follow-Up Visit
A follow-up visit will occur approximately 30 days after the last dose of study drug to 
obtain information on any new or ongoing AE/SAEs and laboratory assessments.
Subjects will complete the follow-up visit when they have either
●
Completed the final study visit and have not enrolled in Study M14-430 OR
●
Prematurely discontinued study drug and study participation.

The follow-up visit is not applicable for subjects who discontinued study drug and 
continued study participation and completed at least one study visit at least 30 days after 
last study visit.
If a follow-up visit is not possible, a telephone call may be possible to collect information 
about new or ongoing AEs.
Study visits may be impacted due to the COVID-19 pandemic or any state of emergency 
or pandemic situation.  If visits cannot be conducted onsite due to travel restrictions or 
other pandemic-related reasons, phone or virtual visits, visits at alternative locations, or 
changes in the visit frequency and timing of study procedures, among others may be 
performed.  Additional details are provided in the subsequent sections.  Every effort 
should be made to ensure the safety of subjects and site staff, while maintaining the 
integrity of the study.

Vaccines
Although not mandated by the protocol, vaccines recommended by local guidelines 
should be considered.  It is recommended that subjects be up to date for recommended 
inactivated, toxoid or biosynthetic vaccines, such as injectable flu vaccine, pneumococcal, 
and pertussis (Tdap) and herpes zoster (Shingrix, non-live recombinant).  If the subject 
and investigator chooses to administer live vaccines, these vaccinations must be 
completed (per local label) at least 30 days (or longer, if required locally [e.g., 8 weeks in 
Japan]) before first dose of study drug with appropriate precautions and are not allowed 
during study participation including at least 30 days (or longer, if required locally) after 
last dose of oral study drug.  Live vaccines are NOT allowed during the study.  If the 
herpes zoster live attenuated vaccine (Zostavax) is to be administered, and there is no 
known history of primary varicella (chicken pox), pre-existing immunity to varicella 
should be confirmed with antibody testing at or prior to screening and prior to 
administration of the herpes zoster vaccine.  If screening varicella antibody testing is 
negative the herpes zoster vaccine should not be administered.
Examples of live vaccines include, but are not limited to, the following:
●
Monovalent live influenza A (H1N1) (intranasal);
●
Seasonal trivalent live influenza (intranasal);
●
Zostavax (herpes zoster, live attenuated);

If the female subject is ≤ 55 years of age AND has had no menses for ≥ 12 months AND 
has no history of permanent surgical sterilization (defined above), FSH should be tested at 
Screening.

●
If FSH is not tested, it is assumed that the subject is of childbearing potential 
and protocol-specified contraception is required.
●
If the FSH is tested and the result is consistent with postmenopausal status, 
contraception is not required.
●
If the FSH is tested and the result is consistent with premenopausal status, 
contraception is required, and pregnancy testing requirements for females of 
childbearing potential must be followed (see Section 5.3.1.1, pregnancy test).
A woman who does not meet the definition of postmenopausal or permanently surgically 
sterile is considered of childbearing potential and is required to practice at least one of the 
following highly effective methods of birth control (for subjects in the US and where 
appropriate per local requirements:  must simultaneously use two of the following highly 
effective methods of birth control; or one of the following highly effective methods of 
birth control PLUS a barrier [condoms, diaphragm or cervical cap] with spermicide) that 
is effective from Study Day 1 (Baseline) (or earlier) through at least 30 days after the last 
dose of study drug:
●
Combined (estrogen and progestogen containing) hormonal contraception 
(oral, intravaginal, transdermal, and injectable) associated with the inhibition 
of ovulation, initiated at least 30 days prior to Study Day 1 (Baseline).
●
Progestogen-only hormonal contraception (oral, injectable, implantable) 
associated with inhibition of ovulation, initiated at least 30 days prior to Study 
Day 1 (Baseline).
●
Bilateral tubal occlusion/ligation.
●
Vasectomized partner(s), provided the vasectomized partner verbally confirms 
receipt of medical assessment of the surgical success and is the sole sexual 
partner.
●
Intrauterine device.
●
Intrauterine hormone-releasing system.
●
True abstinence (if acceptable per local requirements):  defined as refraining 
from heterosexual intercourse when this is in line with the preferred and usual 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
63
lifestyle of the subject (periodic abstinence [e.g., calendar, ovulation, 
symptothermal, post-ovulation methods] and withdrawal are not acceptable).
○
In the US, true abstinence applies only to women of childbearing potential 
who do not have male partners and are not engaging in heterosexual 
intercourse as their preferred and usual lifestyle (periodic abstinence 
[e.g., calendar, ovulation, symptothermal, post-ovulation methods] and 
withdrawal are not acceptable).
If required per local practices, progesterone-only oral hormonal contraception where 
inhibition of ovulation is not the primary mode of action (initiated at least 1 month prior 
to Baseline) male or female condom with or without spermicide OR cap, diaphragm or 
sponge with spermicide should be used in addition to one of the highly effective birth 
control methods listed above (excluding true abstinence).
If during the course of the study a woman becomes surgically sterile or postmenopausal 
and complete documentation is available, contraceptive measures as defined above are no 
longer required.
Contraception recommendations related to use of concomitant therapies prescribed per 
standard of care should be based on the local label.
It is important to note that contraception requirements described above are specifically 
intended to prevent pregnancy during exposure to the investigational therapy upadacitinib.

5.3.1
Efficacy and Safety Measurements Assessed and Flow 
Chart
Study procedures described are listed in the following section of this protocol and are 
summarized in tabular format in Appendix C.
5.3.1.1
Study Procedures
The study procedures outlined in Appendix C are discussed in detail in this section, with 
the exception of optional exploratory research (discussed in Section 5.3.1.2), drug 
concentration measurements (discussed in Section 5.3.2), the collection of prior and 
concomitant medication information (discussed in Section 5.2.3), and the collection of AE 
information (discussed in Section 6.1.1.1).  All study data will be recorded in source 
documents and on the appropriate eCRFs.
Informed Consent
At the Screening Visit, the subject will sign and date a study specific, IEC/IRB approved, 
informed consent form for the study before any study procedures are performed or any 
medications are withheld from the subject in order to participate in this study.  Separate 
written consent will be required for each subject in order to participate in the optional 
exploratory research.  The separate written consent may be part of the main consent form.  
Subjects can withdraw informed consent at any time.
Details regarding how informed consent will be obtained and documented are provided in 
Section 9.3.
Due to the COVID-19 pandemic, any state of emergency or pandemic situation, it is 
possible that additional protocol modifications not outlined in this protocol may become 
necessary.  If this situation arises, in addition to the study informed consent, additional 
verbal consent may be obtained prior to these adaptations or substantial changes in study 
conduct in accordance with local regulations.

65
Inclusion/Exclusion Criteria
Subjects will be evaluated to ensure they meet all inclusion criteria and have none of the 
exclusion criteria at both Screening and Baseline Visits.
Medical and Surgical History
A complete non-CD-related medical and surgical history, including history of alcohol and 
nicotine use, will be taken from each subject during the Screening Visit.  Additionally, a 
list of each subject's CD-related medical and surgical history will be recorded at 
Screening.  Information on prior aminosalicylate, corticosteroid, immunosuppressants 
(e.g., AZA, 6-MP, and MTX) use, biologics, CD-related antibiotics, or any other 
physician prescribed therapy for CD will be obtained as outlined in Section 5.2.3.1.  In 
addition, for subjects in Australia, Japan, China and Taiwan, prior tacrolimus use will be 
asked.  Information for the Montreal classification for CD will be collected at Screening 
for all subjects.
History of herpes zoster, herpes zoster vaccination, and hepatitis B vaccination status will 
be recorded as part of the medical history.  An updated medical history will be obtained 
prior to study drug administration at Baseline, to ensure the subject is still eligible for 
enrollment.
A detailed medical history with respect to TB risk factors will be documented in the study 
source documentation.  This information will include BCG vaccination, cohabitation with 
individuals who have had TB, and travel to, residence in, or work in TB endemic 
locations.
TB Testing/TB Prophylaxis
The TB screening tests are diagnostic test results to be interpreted in the context of the 
subject's epidemiology, history, exam findings, etc., and it is the responsibility of the 
investigator to determine if a subject has previous, active, or latent TB.
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
66
At screening, all subjects will be assessed for evidence of increased risk for TB by a risk 
factor assessment form (Appendix D) and tested for TB infection by QuantiFERON-TB 
Gold test (or IGRA equivalent such as T-SPOT TB test).  The PPD Skin Test (also known 
as a TB Skin Test or Mantoux Test) should be utilized only when a QuantiFERON-TB 
Gold Test is not possible for any reason (unless both tests are required per local 
guidelines).  The site staff will complete the TB risk assessment form and enter the data 
into an appropriate eCRF. 
If a subject had a negative QuantiFERON-TB Gold (and/or PPD) test within 90 days prior 
to Screening and source documentation is available, the test does not need to be repeated, 
provided nothing has changed in the subject's medical history to warrant a repeat test.  
These cases may be discussed with the AbbVie TA MD.  The results of the TB test(s) will 
be retained at the site as the original source documentation.
Subjects with documentation of a prior positive result of QuantiFERON-TB Gold Test (or 
equivalent) or PPD may not repeat either test at Screening or during the study and should 
be considered positive.
TB Test
For regions that require both PPD and QuantiFERON-TB Gold testing, both will be 
performed.  A positive TB test is defined by local guidelines (for example, in some 
countries, both PPD and QuantiFERON-TB Gold are performed, and if either one is 
positive, the TB test is considered positive).
In the absence of local guidelines defining a positive result when both PPD and 
QuantiFERON-TB Gold tests are performed, the TB test is considered positive if either 
one is positive.
If a site has the capacity to perform both PPD and QuantiFERON-TB Gold tests, and local 
guidelines require only one test to be performed, then the QuantiFERON-TB Gold is the 
preferred test.  If a PPD is placed at screening, then the PPD will be the reference TB test 
to be used for the remainder of the program for that subject.  Similarly, if a subject enters 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
67
the study with a QuantiFERON-TB Gold test alone or other IGRA (negative result), then 
any future TB test performed should be a QuantiFERON-TB Gold test.
If the QuantiFERON-TB Gold Test is NOT possible (or if both the QuantiFERON-TB 
Gold Test and the PPD are required per local guidelines):  the PPD will be performed 
according to standard clinical practice.  The TB Skin Test should be read by a licensed 
healthcare professional between 48 and 72 hours after administration.  A subject who does 
not return within 72 hours will need to be rescheduled for another skin test.  The reaction 
will be measured in millimeters (mm) of induration and induration ≥ 5 mm is considered a 
positive reaction.  The absence of induration will be recorded as "0 mm" not "negative."  
Subjects who have had a prior positive PPD test or an ulcerating reaction to the TB Skin 
Test in the past should not be re-exposed and the TB Skin Test should be considered 
positive.
Subjects with a negative TB test and chest x-ray not suggestive of active TB or prior TB 
exposure may be enrolled.
If the QuantiFERON-TB Gold test is indeterminate, the site should repeat the test with 
another blood sample and/or perform a PPD test.  If the second QuantiFERON TB Gold 
test is also indeterminate or positive, then the subject is considered to be positive for the 
purpose of the study.  If the second QuantiFERON-TB Gold test is negative, the subject is 
considered to be negative.
In cases where the Screening QuantiFERON-TB Gold test by the central laboratory is 
positive and the investigator considers the subject at low risk for TB (i.e., no risk factors 
identified using the TB risk assessment form) and has no clinical suspicion of TB, the 
investigator may perform a repeat QuantiFERON-TB Gold test (or IGRA equivalent) at 
the local laboratory or through the central laboratory (if not locally available) to confirm 
the positive test result.  If the repeat testing result is negative, the investigator may 
consider the subject to be negative based on his/her clinical judgment; if the repeat testing 
result is positive or indeterminate, the subject is considered to be positive.
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
68
Subjects with a positive TB test must be assessed for evidence of active TB versus latent 
TB, including signs and symptoms and chest x-ray.  Subjects with no signs or symptoms 
and a chest x-ray not suggestive of active TB may be enrolled after initiation of TB 
prophylaxis (see below).  Subjects with evidence of active TB must not be enrolled.
Subjects with history of active TB may be enrolled if it has been adequately treated with 
no evidence of current active TB; subjects with inadequate documentation of treatment 
should be cleared by a TB specialist prior to enrollment.
TB Prophylaxis
At screening, if the subject has evidence of latent TB infection (no symptoms, positive TB 
test and the subject has a chest x-ray not suggestive of active TB), prophylactic treatment 
must be initiated at least 2 weeks prior to administration of study drug (or per local 
guidelines, whichever is longer).  At least 6 months of prophylaxis needs to be completed; 
however, the full course of prophylaxis does not need to be completed prior to the first 
dose of study drug.  If the investigator deems that it is necessary, consultation with a TB 
expert could be considered.
In case of a subject at low risk for TB (i.e., no risk factors identified using the TB risk 
assessment form), no clinical suspicion of TB, who had a negative confirmatory repeat 
QuantiFERON-TB Gold test result available after initiation of isoniazid, then TB 
prophylaxis can be stopped.
Note:  Rifampicin or rifapentine are not allowed for TB prophylaxis.
Subjects with a prior history of latent TB that have documented completion of a full 
course of anti-TB therapy will be allowed to enter the study provided nothing has changed 
in the subject's medical history to warrant repeat treatment.
For subjects with completion of a full course of anti-TB therapy but insufficient 
documentation the investigator should consult with the AbbVie TA MD.
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
69
Newly initiated prophylactic treatment should be captured in the eCRF and in the source 
documents.  Prior therapy should be captured in the eCRF.
During the study, subjects with new evidence of latent TB should initiate prophylactic 
treatment immediately per local guidelines and complete at least 6 months of prophylaxis.  
Study drug(s) should not be withheld and isoniazid should be initiated and 2 to 4 weeks 
later (per local guidelines), subject should be re-evaluated (unscheduled visit) for signs 
and symptoms of isoniazid toxicity.
If the subject is experiencing signs or symptoms suspicious for active TB or something 
has changed in the subject's medical history to warrant a repeat test, the case (including 
the TB test results) must be discussed with the AbbVie TA MD.
Chest X-Ray
Chest x-ray (posterior-anterior view and lateral view) is required (in Japan and China, a 
computerized tomography [CT] scan of the chest may be performed in lieu of a chest 
x-ray, at the investigator's discretion) for all subjects at Screening to rule out the presence 
of TB or other clinically relevant findings.
The chest x-ray will not be required if the subject had a previous normal chest x-ray 
(posterior-anterior and lateral views) (or normal CT Scan of the chest for subjects in Japan 
and China) within 90 days of Screening, provided all source documentation is available at 
the site, as outlined below and provided nothing has changed in the subject's medical 
history to warrant a repeat test.
Subjects can have a repeat chest x-ray at any time during the study as warranted based on 
the opinion of the investigator.
A radiologist or pulmonologist must perform an assessment of the chest x-ray (or CT scan 
of the chest).  The principal investigator will indicate the clinical significance of any 
findings and will sign and date the report.  In the assessment of the chest x-ray (or CT 
scan of the chest for subjects in Japan and China), the principal investigator or their 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
70
designee must indicate the presence or absence of (1) calcified granulomas, (2) pleural
scarring/thickening, and (3) signs of active TB.  If the chest x-ray demonstrates changes 
suggestive of previous TB (e.g., calcified nodule, fibrotic scar, apical or basilar pleural 
thickening) or other findings that are clinically significant, the principal investigator 
should contact the AbbVie TA MD before enrolling the subject.
12-Lead Electrocardiogram (ECG)
For all subjects, a resting 12-lead ECG will be performed at screening, as specified in 
Appendix C.  A qualified physician will interpret the clinical significance of any abnormal 
finding, sign, and date each ECG.  ECGs with QT interval corrected for heart rate using 
Fridericia's correction formula (QTcF) should be reported (or calculated) and documented 
in the source documents and later transcribed on to the appropriate eCRF if QTcF 
prolongation is observed.  A valid QTcF cannot be calculated in subjects who have a 
pacemaker or supraventricular or ventricular conduction abnormalities.  In cases of QTcF 
prolongation, the baseline QTcF will need to be entered into the appropriate eCRF for 
comparison as well.  In addition, any clinically significant findings will be documented in 
the source documents and later transcribed on to the appropriate eCRF.  Each signed 
original ECG will be monitored by the responsible site monitor and kept with subject's 
source documents onsite.
For subjects with a normal ECG taken within 90 days of Screening, a repeat ECG at 
Screening will not be required, provided source documentation is available and provided 
nothing has changed in the subject's medical history to warrant a repeat ECG.  If there are 
other findings that are clinically significant, the investigator must contact the AbbVie TA 
MD before enrolling the subject.
Subjects can have a repeat ECG at any time during the study as warranted based on the 
opinion of the investigator.
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
71
At Week 12 or Week 24, in the event this may not be performed due to the COVID-19 or 
any pandemic, the site should perform the 12-lead ECG at the next earliest feasible visit 
or arrange to have an alternative acceptable local facility perform the ECG.
Height and Weight
Height will be measured at the Screening Visit only (with shoes off).  Body weight will be 
measured at all scheduled visits, as specified in Appendix C.  All measurements will be 
recorded in metric units where applicable.
Vital Signs
Vital sign determinations of systolic and diastolic BP in sitting position, pulse rate, 
respiratory rate, and body temperature will be obtained at visits specified in Appendix C.  
BP, pulse rate, body temperature, and respiratory rate should be performed before blood 
draws are performed.
Physical Examination
A complete physical examination will be performed at Screening, Baseline, Week 12, and 
Week 24/PD as specified in Appendix C and must include an assessment of EIMs and 
fistulas.  The physical examination at the Baseline Visit will serve as the baseline physical 
examination for the entire study.  Physical examinations at all other visits (including 
unscheduled visits) are symptom based and should include the assessment of EIMs and 
presence or absence of fistulas as part of calculating the CDAI.  The presence or absence 
of (1) arthritis/arthralgia, (2) iritis/uveitis, and (3) erythema nodosum, pyoderma 
gangrenosum, and aphthous stomatitis will be collected for the assessment of EIMs.
At Baseline, Week 12, and Week 24/PD, the number of fissures, draining and non-
draining enterocutaneous (perianal and abdominal) and rectovaginal fistulas should be 
recorded, including the number of fistulas draining upon gentle compression.  
Enterocutaneous fistulas will be considered draining when there is drainage upon gentle 
compression, and rectovaginal fistulas will be considered draining based on either 
presence of drainage on physical examination or presence of relevant symptoms (e.g., 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
72
passage of rectal material or flatus from the vagina).  A complete examination of the 
presence and number of draining and non-draining fistulas during Screening or during the 
visit for endoscopy at Screening, Week 12 or Week 24/PD may be used for the Baseline, 
Week 12 or Week 24/PD visits, respectively, and does not need to be repeated at the 
respective visit.
Physical examination abnormalities noted by the investigator at Baseline prior to the 
first dose of study drug will be recorded in the subject's medical history; abnormalities 
noted after the first dose of study drug will be evaluated and documented by the
investigator as to whether or not the abnormality is an AE (see Section 6.1.1.1 for AE 
definition).  All findings, whether related to an AE or part of each subject's medical 
history, will be captured on the appropriate eCRF page.
At any time, a symptom-directed physical examination can be performed as deemed 
necessary by the investigator.
Pregnancy Test
A serum pregnancy test will be performed for all female subjects of childbearing potential 
at the Screening Visit.  The serum pregnancy test will be sent to and performed by the 
central laboratory.  If the serum pregnancy test is positive the subject is considered a 
screen failure.  If the serum pregnancy test is borderline, it should be repeated ≥ 3 days 
later to determine eligibility.  If the repeat serum pregnancy test is:
●
Positive, the subject is considered a screen failure;
●
Negative, the subject can be enrolled into the trial;
●
Still borderline ≥ 3 days later, this will be considered documentation of 
continued lack of a positive result and the subject can be enrolled into the 
study in the absence of clinical suspicion of pregnancy and other pathological 
causes of borderline results.
A urine pregnancy test will be performed for all female subjects of childbearing potential 
at the Baseline Visit prior to the first dose of study drug and at all subsequent visits.  More 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
73
frequent pregnancy tests will be performed throughout the study if required per 
local/country requirements.
If the baseline urine pregnancy test performed at the site is negative, then dosing with 
study drug may begin.
If the baseline urine or a postbaseline pregnancy test performed at the site is positive, 
dosing with study drug must be withheld and a serum pregnancy test is required.  The 
serum pregnancy test will be sent to and performed by the central laboratory.  If the serum 
pregnancy test is negative, study drug may be started or resumed.  If the serum pregnancy 
test is positive, study drug must be permanently discontinued.  In the event a pregnancy 
test comes back borderline, a repeat test is required, as described above.
At each visit, the study staff should review the pregnancy avoidance recommendations 
with each female subject of childbearing potential and document this discussion in the 
subject's source records.
If during the course of the study a woman becomes surgically sterile or postmenopausal 
and complete documentation as described in Section 5.2.4 is available, pregnancy testing 
is no longer requested.
A pregnant or breastfeeding woman will not be eligible for participation in the study or be 
allowed to continue study drug.
During the COVID-19 or any pandemic-related restrictions, urine pregnancy tests may be 
performed at the local laboratory or at home and confirmed by site staff via phone, 
telemedicine, or video call.  Pregnancy test results must be available before drug 
dispensation.
Hepatitis Screen
All subjects will be tested for the presence of HBV and HCV at Screening.
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
74
Hepatitis B
Subjects will be tested for the presence of HBV at screening using the following tests:
●
HBs Ag (Hepatitis B surface antigen)
●
HBc Ab/anti-HBc (Hepatitis B core antibody)
●
HBs Ab/anti-HBs (Hepatitis B surface antibody)
HBV serologic test results will be interpreted and managed as shown in Figure 2.
A positive result for HBs Ag will be exclusionary.
A negative result for HBs Ag will trigger (automatic reflex testing) for core antibodies 
(HBc Ab) and surface antibodies (HBs Ab).
For a subject who has had a HBV vaccination (should document in the medical history), a 
positive test result for HBs Ab is expected, the HBV DNA PCR qualitative testing is not
required and the subject may be enrolled (Scenario B).
A negative test result for HBc Ab does not require HBV DNA PCR qualitative testing 
and the subject may be enrolled (Scenarios A and B).
A positive test result for HBc Ab requires HBV DNA PCR testing (automatic reflex 
testing) (Scenarios C and D).
●
A positive result for HBV DNA or a result that exceeds detection sensitivity 
will be exclusionary.
●
A subject with a negative result for HBV DNA may be enrolled.
Where mandated by local requirements, subjects with positive HBs Ab and/or positive 
HBc Ab and a negative HBV DNA PCR test at Screening, should have HBV DNA PCR 
test performed at every 12 weeks.  HBV DNA PCR testing every 12 weeks is not 
necessary when the subject has a history of HBV vaccine and HBs Ab+.  In cases where 
recurrence of HBV DNA is observed, the subject should be discontinued from the study.

A positive test result for HBs Ab is expected for subjects who have had a HBV vaccination.  For subjects without a 
history of HBV vaccination (and for subjects in Japan) a positive result for HBs Ab/anti-HBs requires HBV DNA 
PCR testing.
**
In the event that the HBV DNA PCR cannot be performed due to the COVID-19 or any pandemic, perform the 
HBV DNA PCR at the next earliest feasible visit of arrange to have it completed by a local laboratory.
Hepatitis C
Blood samples for Hepatitis C serology will be obtained at the Screening Visit.  A 
positive HCV Ab will trigger an HCV RNA test.  A subject will not be eligible for study 
participation if test results indicate active Hepatitis C (HCV RNA detectable in any 
subject with anti HCV Ab).
HIV
Subjects with HIV infection (positive HIV test result) are excluded from study 
participation.  HIV testing will be performed at Screening, unless prohibited by local 
regulations.  The investigator must discuss any local reporting requirements to local health 
agencies with the subject.  The site will report confirmed positive results to their health 
agency per local regulations, if necessary.  If a subject has a confirmed positive result, the 
investigator must discuss with the subject the potential implications to the subject's health

and subject should receive or be referred for clinical care promptly.  AbbVie will not 
receive results from the testing and will not be made aware of any positive result.
Clinical Laboratory Tests
Samples will be obtained for the clinical laboratory tests listed in Table 2 and at visits 
specified in Appendix C.  Unscheduled clinical labs may be obtained at any time during 
the study if deemed appropriate per the investigator's discretion.  A certified central 
laboratory will be utilized to process and provide results for the clinical laboratory tests.
The central laboratory chosen for this study will provide instructions regarding the 
collection, processing, and shipping of these samples.
Blood draws should be performed, as much as possible, only after all questionnaires, 
clinical assessments, and vital sign determinations are obtained.
For blood sampling, subjects should be fasting (a minimum 8-hour fast) whenever 
possible.  If a subject is not able to fast when necessary, the non-fasting status will be 
recorded in study source documentation.
For any laboratory test value outside the reference range that the investigator considers to 
be clinically significant, the investigator should apply the standard of care for medical 
evaluation and treatment per local guidelines:
●
The investigator will repeat the test to verify the out-of-range value.
●
The investigator will follow the out-of-range value to a satisfactory clinical 
resolution.
A laboratory test value that requires a subject to be discontinued from study drug or 
requires a subject to receive treatment will be recorded as an AE.  Other laboratory 
abnormalities, including those which meet the toxicity management criteria outlined in 
Section 6.1.7, may be recorded as AEs at the discretion of the investigator.

Lymphocyte subsets include T (CD4+ and CD8+) cells, B (CD19+) cells, NK cells, and natural killer 
T (NKT) cells.
h.
A urine pregnancy test will be performed for all female subjects of childbearing potential at the Baseline Visit prior 
to the first dose of study drug and all subsequent visits.
i.
During Screening, biologic drug levels may be optionally assessed at the investigator's discretion as an alternative 
to completing the required washout period: (1) infliximab and natalizumab: may be tested approximately 4 weeks 
from the last dose; (2) adalimumab, certolizumab, golimumab, or vedolizumab: may be tested approximately
6 weeks from the last dose; (3) ustekinumab: may be tested approximately 8 weeks from the last dose.
If travel restrictions or other changes in local regulations in light of the COVID-19 
pandemic or any state of emergency or pandemic situation prevent the subject from 
having blood drawn for laboratory testing at the study site, if possible, sites should 
arrange for subjects to have laboratory work done at a local laboratory, hospital, or other 
facility.  It is recommended to perform all scheduled tests in the protocol, except for 
hs-CRP, fecal calprotectin, PK, lymphocyte subsets, and optional samples for exploratory 
research which should not be collected.  Local laboratory results should be obtained along 
with reference ranges and kept within the subject's source documentation.  Local 
laboratory results should be reviewed by the investigator and documented in EDC as an 
unscheduled laboratory visit as soon as possible. 
If it is not possible to perform all of the laboratory tests locally, the minimum laboratory 
tests presented below should be performed for safety evaluation.

section below.
Other Laboratory Assessments
High-Sensitivity C-Reactive Protein (hs-CRP)
Blood samples for hs-CRP will be obtained as specified in Appendix C.  The hs-CRP 
results will remain blinded to the sponsor, investigator, study site personnel and the 
subject.  The hs-CRP test will be performed by the central lab.
Local laboratory or site testing for hs-CRP is not allowed after Baseline.  Results of hs-
CRP may unblind the treatment assignment, and the results may be blunted in subjects 
taking a JAK inhibitor, thereby limiting clinical utility in the setting of a safety 
assessment or AE management. Any local testing of hsCRP or CRP during the 
placebo-controlled portion of the study is therefore strongly discouraged and any local 
hs-CRP or CRP tests reported to the investigator prior to the primary endpoint assessment 
will be recorded as protocol deviations.

Urinalysis
Dipstick urinalysis (macroscopic analysis) will be completed by the central laboratory at 
all required visits as listed in Appendix C.  A microscopic urinalysis will only be 
performed by the central laboratory if the dipstick urinalysis results are abnormal, where 
abnormal is defined as leukocytes, nitrite, ketone, protein, blood, or glucose value of 
greater than a trace.
Lymphocyte Subsets
Blood samples will be collected at specified visits (Appendix C) to assess lymphocyte 
subsets:  T (CD4+ and CD8+) cells, B (CD19+) cells, NK cells, and NKT cells.  These 
tests will be performed by the central lab.
Stool Samples
Fecal Calprotectin (FCP)
FCP will be performed for all subjects as indicated in Appendix C.  Subjects will be asked 
to provide a stool sample, subjects will be sent home with instructions and a stool sample 
supplies.  All stool samples should be collected before any bowel preparation for 
endoscopy is started.
The FCP results will remain blinded to the sponsor, investigator, study site personnel and 
the subject throughout the study.  Local laboratory or site testing for fecal calprotectin is 
not allowed after Baseline.
The central laboratory will be utilized to process and provide results for these laboratory 
tests.
Clostridium difficile Toxin
During the Screening Period, a stool sample will be collected and sent to the central 
laboratory for testing.  The sample will be assessed for the presence of C. difficile toxin.
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
81
The sample must be shipped to the central laboratory using dry ice.  Additional 
information is available in the Investigator Manual provided by the central laboratory.
If a second sample collection is needed due to unforeseen issues with the first sample 
(e.g., missing sample, stability issues, inadequate sample, etc.), all efforts must be made to 
ship the second sample to the central laboratory using dry ice.  On an exceptional basis, 
and after consultation with the AbbVie TA MD, this second sample may be sent to the 
local lab for testing.
Subjects who are positive for C. difficile toxin should be screen-failed; these subjects may 
be re-screened after completing the appropriate treatment.
Outcomes and Questionnaires
The following outcomes and questionnaires will be completed at the time points as 
indicated in Appendix C.  Refer to Appendix E for descriptions of Patient Reported 
Outcomes.
●
Inflammatory Bowel Disease Questionnaire (IBDQ)
●
Work Productivity and Activity Impairment Questionnaire (WPAI)-CD 
●

During the COVID-19 pandemic or any state of emergency or pandemic situation, when 
an onsite visit cannot be performed, all questionnaires except EQ-5D-5L scale are eligible 
for completion by phone or virtual interview.  Prior to the phone/virtual visit, the site staff 
person should be delegated this task on the Delegation of Authority log.  Sites will read 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
82
the PRO questions and response options to the subject and record the subject's responses.  
The subject's ability to view the PRO to understand the questions and response options 
should be preserved.  Sites must share a local language version of the questionnaire by 
videoconference or send the questionnaires (email or hard copy) to the subjects to allow 
them to read/understand the questions and responses when the subject is providing 
responses remotely.  The date and start and stop time of PRO data collection should be 
recorded along with the name of the person who collected the information, their role, and 
which questionnaires were completed.
Subject Diary
Subjects will be dispensed an electronic diary at Screening and will be trained on how to 
complete the diary by site staff during the Screening Visit.  All subjects should complete 
their subject diary on a daily basis throughout the entire study.  The diary will be reviewed 
by site personnel with the subject at each visit and collected at the Final/PD Visit, unless 
the subject continues into Study M14-430. 
In case of missing diary information, or when discrepancies are discovered, site personnel 
should discuss with the subject and document changes in site records, if applicable.  
Completion will be reinforced during study visits as necessary.
Remote Visits Due to the COVID-19 or any Pandemic
If visits cannot be conducted onsite due to travel restrictions or other pandemic-related 
reasons, phone or virtual (remote) visits, or visits at alternative locations may be 
performed.  These visits should occur within 7 days of the planned date, if possible.  
During these visits, the following procedures should be performed:
●
Adverse event assessment
●
Concomitant medications
●
Compliance to contraception (if applicable) 
●
Monthly pregnancy testing results (if applicable)
●
IP compliance/dosing and drug accountability

●
Confirm subject diary entries
●
Weight (may be performed by the subject or caregiver)
●
Vital signs (may be obtained by the subject or caregiver)
●
Questionnaires:  All questionnaires except EQ-5D-5L scale are eligible for 
completion by remote interview at all visits.  If there are time constraints to the 
remote visit, at a minimum, the following must be completed:  IBDQ, 
FACIT-F, PGIC, PGIS.
Assessments that require physical examination (e.g., gentle compression of fistulas, etc.) 
should not be performed.
The site must keep records of all remote visits.
Study Drug Dispensing/Administration
Study drug will be dispensed to subjects at Baseline, Week 4, and Week 8 in Part 1.  
Subjects that continue into Part 2 will have study drug dispensed at Week 12, Week 16, 
and Week 20.
Study drug will be taken orally once daily (QD) beginning at the Baseline visit, and 
should be taken at approximately the same time each day.  
Refer to Section 5.5 for additional information.
If a subject is unable to come to the study site for drug dispensation due to COVID-19 or 
any pandemic, a direct-to-patient (DTP) study drug shipment can be made from the study 
site to the subject if allowed by local regulations.  AbbVie will submit any required 
notifications to the regulatory authority as applicable.
DTP study drug shipments will be removed once the pandemic is considered to be 
resolved.
Study drug may be dispensed, and study drug administration may be continued if 
laboratory samples cannot be obtained, provided that all the following criteria are met:
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
84
1.
There is at least 1 post-baseline laboratory assessment,
2.
The investigator has reviewed all prior laboratory results and confirms and 
discusses with the subject via a phone/video call that there is no safety concern for 
the subject to continue use of the study drug in the absence of current labs, 
3.
No longer than 6 weeks have passed from the last safety laboratory tests.
Crohn's Disease Activity Index (CDAI)
Average daily very soft or liquid SF, average daily AP score, and well-being will be 
calculated from the subject diary.  During screening subjects will be instructed on how to 
calculate the number of very soft and liquid stools, including a visual depiction based on 
the Bristol Stool Chart.  Physical exam and appropriate laboratory values will be 
calculated at all study visits, except the 30-day follow-up visit, beginning at Baseline.  
The Screening period will be a minimum of 8 days to calculate the Baseline scores.
The CDAI scores must be calculated using a hematocrit (Hct) value from the same visit 
laboratory work.  The final CDAI for each visit will be calculated once the Hct value is 
received from the central lab.  If the Hct is missing due to technical issues (e.g., lost 
sample, clotted sample, etc.), the Hct value from the preceding visit may be used.
Instructions to Calculate CDAI
●
To answer questions one (1) through three (3), entries from the 7 days prior 
to the visit should be used as recorded by the subject from the diary.
●
Diary entries should not be included in the 7 days evaluated prior to the visit 
if:  (1) the day the subject received medication for bowel preparation prior to 
endoscopy, (2) the day the subject underwent an endoscopy, and (3) 2 days 
following the endoscopy.  Diary entries, up to 14 days prior to the visit, will be 
used accordingly in order to provide the most recent data for 7 days prior to the 
respective study visit.  The 7 days do not need to be consecutive.
●
In question four (4), for the section regarding presence of anal fistulas and 
other fistulas, all fistulas detectable on physical examination (draining and 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
85
non-draining) should be captured on the CDAI and calculated into the CDAI 
score.
●
The evaluation for fever should include all the days that are taken into account 
for the calculation of the CDAI.
●
When completing question five (5) ("Taking 
Lomotil/Imodium/Loperamide/opiates for diarrhea, 0 = no, 1 = yes") on the 
CDAI, "no" should be answered if a subject is taking an opiate(s) solely for 
pain.  The use of these medications takes into account only the day of the 
scheduled visit and is only assessing their use as anti-diarrheals.
●
For question seven (7), Hct results from central laboratory will be used for the 
CDAI calculation.  If the Hct value contains more than one decimal point, the 
rounding will be allowed to the tenths decimal (e.g., Hct value 33.44 will be 
captured as 33.4, Hct value of 33.45 will be captured as 33.5).  The Hct values 
either prior to completing the calculation or at the subtotal box 7 of the CDAI 
should not be rounded to a whole number.
●
For question eight (8), the height obtained at Screening should be used when 
selecting the standard weight in Appendix H, and this standard weight should 
be used for calculating every CDAI throughout subject participation in the 
study.
●
Standard height is calculated by using the height obtained at Screening 
(without shoes) adding 1 inch or 2.5 cm.
●
If the body weight obtained at the time of assessment is not captured in 
kilograms (kg), then when converting into kg, rounding should occur using the 
second digit after the decimal (also known as the hundredth place) where if the 
number is 0 – 4, then keep the first digit after the decimal (also known as the 
tenth place) unchanged.  If the second digit after the decimal is 5 – 9, then 
round up the first digit after the decimal (e.g., 90.246 would be captured as 
90.2 and 97.687 would be captured as 97.7).
●
The subtotal of box 8 should not be rounded to a whole number.
The calculation of the CDAI score is in Appendix I.

86
Endoscopy
An endoscopy (ileocolonoscopy) will be performed as specified in Appendix C.  It is 
expected that all subjects who remain in the study through at least Week 8 will have a 
Week 12/PD endoscopy in Part 1.  For subjects entering Part 2, it is expected that all 
subjects who remain in the study through at least Week 20 will have a Week 24/PD 
endoscopy.  An endoscopy performed before the Screening visit, independently of the 
study, may be used as the Screening endoscopy, with the approval of the AbbVie TA MD, 
if the following conditions are met:
1.
Biopsy confirmation of the diagnosis is available according to section "Biopsy 
During Endoscopy" below, as applicable.
2.
The endoscopy took place within 45 days prior to Baseline visit.
3.
The endoscopy was recorded in a video format as the endoscopic eligibility will be 
determined by the central reviewers.
The same endoscopist, where possible, should perform all endoscopies.  In addition, 
where possible, the investigator or sub-investigator should be the endoscopist for the 
study.
During the COVID-19 or any pandemic, the Week 12 and Week 24 endoscopies may be 
performed within 7 days of the planned date, if travel restrictions or other pandemic-
related reasons impact scheduling.  If the endoscopy cannot be performed at the study site, 
it can be completed at a different hospital/facility. 
If the COVID-19 or any pandemic precludes a subject from undergoing an endoscopy at 
Week 12 or Week 24 and clinical response was achieved, the subject can enroll in 
Study M14-430.
All endoscopies will be reviewed by a central reviewer who is blinded.
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
87
There will be a window of 7 days prior to the scheduled visit to conduct the endoscopy, 
with the exception of the screening endoscopy.  This window may be extended as 
necessary after consultation with the AbbVie TA MD in case of external, not subject-
related circumstances (e.g., scheduling conflict).
The endoscopies performed at the time points described above will be used to provide the 
endoscopy subscores to calculate the SES-CD.  All attempts should be made by the 
endoscopist to explore all segments of the colon and terminal ileum, including intubation 
of the terminal ileum, at every endoscopy visit.  The endoscopy subscores by segment will 
be noted in the subject's source documents and in the database but the central reviewer's 
endoscopy subscore will be used for the efficacy analyses.
Biopsy During Endoscopy
Appropriate documentation of biopsy results consistent with the diagnosis of CD, in the 
assessment of the investigator, must be available in order to confirm the subject's 
eligibility for the study.  If this documentation is not available, a diagnostic biopsy from 
the most affected observed area of the colon must be performed during the Screening 
endoscopy and read by a qualified local pathologist and the results reviewed by the 
investigator.  Biopsies to rule out dysplasia and colon cancer may be taken per the 
investigator's discretion during any endoscopy performed during this study and evaluated 
by the local pathologist.
If any biopsy sample(s) are obtained, it should also be recorded on the video.
Any biopsy sample(s) will be collected from the respective bowel segment during the 
withdrawal of the endoscope and after sufficient recording for the central reader to 
calculate the SES-CD.
The signed pathology report will be monitored by the responsible clinical research 
associate and kept with the subject's source documents onsite.  Subjects should not be 
enrolled if high grade colonic dysplasia or colon cancer is discovered at Screening 
endoscopy or endoscopy performed within 45 days prior to Baseline visit.  Subjects may 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
88
be enrolled if low grade colonic dysplasia is discovered during endoscopy and is 
completely removed.
If a diagnosis of high grade colonic dysplasia or colon cancer is discovered during any 
subsequent endoscopic evaluation during the course of the study, the findings should be 
recorded as an AE and the subject should be discontinued from the study.  If low grade 
colonic dysplasia is discovered during any subsequent endoscopic evaluation during the 
course of the study, the findings should be entered as an AE and the subject can continue 
in the study if the lesion has been completely removed.
Subjects who consent to participate in the substudy to collect intestinal biopsies for 
histologic assessment and exploratory research will have samples collected at Screening, 
Week 12/PD in Part 1 and Week 24/PD in Part 2, as described in Section 5.3.1.2.1 and the 
laboratory manual.
Corticosteroid Taper
Subjects who enter the study on oral corticosteroids are not allowed to change the 
corticosteroid dose during the first 4 weeks of the induction treatment period.  Doses of 
corticosteroids may be decreased during the first 4 weeks only in the event of moderate-
to-severe treatment related toxicities.
At Week 4, subjects who are on prednisone (or oral equivalent) or oral budesonide must 
have their corticosteroid dose tapered according to the proposed schedule in Appendix G.  
Subjects who enter the study on oral budesonide MMX® (e.g., Cortiment®, Uceris®) or 
oral beclomethasone must discontinue their corticosteroid at Week 4.
During Part 1, if a subject is unable to tolerate the corticosteroid taper, the subject may 
have the taper stopped or their corticosteroid dose increased prior to Week 10, per the 
investigator's discretion, up to the dose used at Baseline.  Increasing the corticosteroid 
dose is not allowed at Week 10 through Week 12.  Initiating locally acting (rectal or 
suppository) or systemic corticosteroids is prohibited during Part 1.
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
89
Subjects who do not achieve clinical response at Week 12 and enter in Part 2 and have not 
completed the corticosteroid taper, must resume and proceed with the taper at Week 16, 
following the schedule in Appendix G.  During Part 2, if a subject is unable to tolerate the 
corticosteroid taper, the subject may have the taper stopped or their corticosteroid dose 
increased prior to Week 22, per the investigator's discretion, up to the dose used at 
Baseline.  Increasing the corticosteroid dose is not allowed at Week 22 through Week 24.  
Initiating locally acting (rectal or suppository) or systemic corticosteroids is prohibited 
during Part 2.
Optional Home Healthcare Service Due to the COVID-19 Pandemic or a State of 
Emergency or Pandemic Situation
Subjects may be offered the option of home healthcare visits provided by a study nurse or 
third-party vendor.  Study procedures conducted in the home setting may include vital 
signs, weights, physical examination, safety assessments, compliance to the ePRO entries, 
study medication and contraception, pregnancy test, blood, stool, and urine sample 
collection, if applicable.  This option can only be offered in countries and sites that 
comply with local regulatory and IRB/IEC requirements for home care.  Any pre-requisite 
submission or notifications to the site IRB/IEC and local competent health authority 
should be made, and approvals must be obtained prior to implementation.  The 
investigator should be available via phone call if consultation is necessary.  
Finally, it is recommended that medical personnel entering a subject's home adhere to 
local health regulations during the pandemic such as the use of Personal Protective 
Equipment (PPE), as required. 
Sites may perform home healthcare visits after the following requirements are met:
1.
Confirmation that the subject's safety assessments have been reviewed by the 
principal investigator and that home assessment is appropriate.
2.
Confirmation that the subject's written consent to home healthcare has been 
obtained.  If the home visits will not be performed by site personnel, the site may 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6

be responsible for selecting a vendor, contracting with a vendor, and for ensuring 
continued compliance with the terms of the Clinical Study Agreement.
5.3.1.2
Collection and Handling of Optional Samples for 
Exploratory Research
Subjects will have the option to provide samples for exploratory research.  Subjects may 
still participate in the main study even if they decide not to participate in this optional 
exploratory research.  The procedures for obtaining and documenting informed consent 
are discussed in Section 9.3.
AbbVie (or people or companies working with AbbVie) will store the exploratory 
research samples in a secure storage space with adequate measures to protect 
confidentiality.  The samples will be retained while research on upadacitinib (or drugs of 
this class) or CD and related conditions continues, but for no longer than 20 years after 
study completion.
The following samples will be collected according to Appendix C from each subject who 
consents to provide samples for exploratory research:
●
Blood samples for pharmacogenetic and epigenetic analyses (DNA)
●
Blood samples for transcriptomic and/or epigenetic analyses (RNA)
●
Serum and plasma samples for systemic analyses including, but not limited to, 
proteomics
●
Stool samples for biomarker analyses including but not limited to proteomics 
and microbiota analysis in approximately 100 subjects (fecal biomarker 
substudy).
Samples will be shipped to AbbVie or a designated laboratory for analyses or long-term 
storage.  Instructions for the preparation and shipment of the samples will be provided in 
the laboratory manual.

manual.
5.3.2
Drug Concentration Measurements
5.3.2.1
Collection of Samples for Analysis
Blood samples for assay of upadacitinib will be collected at each visit beginning at 
Week 2.  On the Week 4 visit day, if possible, subjects should take the oral study drug 
dose at the clinic after collecting the PK blood sample, except if the subjects regularly 
take the study drug dose at night.  Those subjects who regularly take the oral study drug 
dose at night should continue to take oral study drug according to their normal schedule.  
For all other visits, subjects can take the oral study drug dose on visit days at their regular 
schedule and not necessarily at the clinic.
For all PK samples, the date and accurate time of the PK sample collection will be 
recorded on the lab requisition form.  The date and accurate time of the last two study 
drug doses will be recorded on the eCRF to the nearest minute.
Blood samples for the screening of prior biologics treatment (infliximab, natalizumab, 
adalimumab, certolizumab, golimumab, vedolizumab or ustekinumab) may be collected 
according to Appendix C.

Detailed instructions for the handling and processing of plasma and serum samples will be 
provided by the central laboratory.  The plasma samples will be shipped to the central 
laboratory.  Upadacitinib plasma concentration will be determined at AbbVie.
Instructions for the preparation and shipment of samples will be provided in the laboratory 
manual.  The serum samples for biologics testing will be shipped to the central lab.
5.3.2.3
Disposition of Samples
The frozen plasma samples for upadacitinib assays and samples for biologics testing will 
be packed in dry ice sufficient to last during transportation and shipped from the study site 
to the central laboratory according to instructions in the central laboratory Lab Manual.  
An inventory of the samples included will accompany the package.
5.3.2.4
Measurement Methods
Plasma concentrations of upadacitinib will be determined under the supervision of the 
Drug Analysis Department at AbbVie using validated liquid chromatography/mass 
spectrometry methods.  Any additional metabolite(s) may be analyzed using non-validated 
methods.
Serum levels of biologics will be determined under the supervision of the drug analysis 
department at AbbVie.

Safety Variables
Safety analyses will be performed on all subjects who receive at least one dose of study 
drug.  Incidence of AEs, changes in vital signs, physical examination results, and clinical 
laboratory data will be assessed throughout the study.
5.3.5
Pharmacokinetic Variables
Plasma upadacitinib concentrations will be obtained at the times indicated in Appendix C.  
A non-linear mixed-effects modeling approach will be used to estimate the population 
central values and the empirical Bayesian estimates of the individual values of 
upadacitinib oral clearance (CL/F) and volume of distribution (V/F).  Additional 
parameters may be estimated if useful in the interpretation of the data.

5.3.6
Optional Exploratory Research Variables
Optional samples may be collected to conduct exploratory investigations into known and 
novel biomarkers.  The types of biomarkers to be analyzed may include, but are not 
limited to, nucleic acids, proteins, lipids or metabolites.  The samples may be analyzed as 
part of a multi-study assessment of factors influencing the subjects' response to the study 
drug (or drugs of the same or similar class) or the development and progression of the 
subjects' disease or related conditions.  The samples may be analyzed for genetic factors 
contributing to the subject's response to study treatment, in terms of pharmacokinetics, 
tolerability, and safety.  Such genetic factors may include genes for drug metabolizing 
enzymes, drug transport proteins, genes within the target pathway, or other genes believed 
to be related to drug response.  Genomic testing and analysis may involve (but is not 
limited to) sequencing of single nucleotide polymorphisms (SNPs), whole exomes, whole 
genomes and epigenetics.  RNA testing and analysis may involve (but not limited to) 
sequencing and expression of all classes (i.e., microRNA [miRNA], long non-coding 
RNA [lncRNA], piwi interacting RNA [piRNA] etc.) of RNA.  The samples may also be
used to develop new diagnostic tests, therapies, research methods or technologies.  The 
results from these analyses are exploratory in nature and may not be included with the 
study report.
5.4
Removal of Subjects from Therapy or Assessment
5.4.1
Discontinuation of Individual Subjects
Subjects can request to be discontinued from participating in the study at any time for any 
reason including but not limited to disease progression or lack of response to treatment.  
The investigator may discontinue any subject's participation for any reason, including but 
not limited to disease progression, lack of response to treatment, an AE, safety concerns, 
or failure to comply with the protocol.  See Section 6.1.7 for toxicity management criteria.
Subjects will have study drug discontinued immediately if any of the following occur:
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
102
●
Clinically significant abnormal laboratory results or AEs, which rule out 
continuation of the study drug, as determined by the investigator or the 
AbbVie TA MD.
●
Serious infections (e.g., sepsis), which would put the subject at risk for 
continued participation in the trial as determined by the investigator.
●
The investigator believes it is in the best interest of the subject, including 
subjects with no improvement to study drug at Week 12 for whom the 
investigator believes it is not in the best interest of the subject to enter in the 
Extended Treatment Period.
●
The subject requests withdrawal from the study.
●
Inclusion or exclusion criteria violation was noted after the subject started 
study drug, when continuation of the study drug would place the subject at risk 
as determined by the AbbVie TA MD.
●
Introduction of prohibited medications or dosages when continuation of the 
study drug would place the subject at risk, as determined by the AbbVie TA 
MD.
●
Subject is non-compliant with TB prophylaxis (if applicable) or develops 
active TB at any time during the study.
●
The subject becomes pregnant while on study drug.
●
Malignancy, except for localized NMSC or carcinoma in-situ of the cervix.
●
Subject is significantly non-compliant with study procedures, which would put 
the subject at risk for continued participation in the trial as determined by the 
investigator or the AbbVie TA MD.
●
Subject develops a gastrointestinal perforation (other than appendicitis or 
mechanical injury).
●
Confirmed diagnosis of deep vein thrombosis, pulmonary embolus or 
noncardiac, nonneurological arterial thrombosis.  See Section 6.1.7 Toxicity 
Management.
During the COVID-19 pandemic or any state of emergency or pandemic situation, 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 AbbVie TA MD before 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
103
discontinuing a subject from the study for a reason other than "planned per protocol," to 
ensure all acceptable mitigation steps have been explored.
In order to minimize missing data for efficacy and safety assessments, subjects who 
prematurely discontinue study drug treatment or study participation should complete a PD 
visit as described in Section 5.1.
All attempts must be made to determine the date of the last study drug dose and the 
primary reason for discontinuation of study drug or study participation.  The information 
will be recorded on the appropriate eCRF page.  However, these procedures should not 
interfere with the initiation of any new treatments or therapeutic modalities that the 
investigator feels are necessary to treat the subject's condition.  Following discontinuation 
of study drug, the subject will be treated in accordance with the investigator's best clinical 
judgment irrespective of whether the subject decides to continue participation in the study.
Lost to Follow-Up
For subjects that are considered lost to follow-up, reasonable attempts must be made to 
obtain information on the final status of the subject.  At a minimum, two phone calls must 
be made and one certified letter must be sent.
5.4.2
Discontinuation of Entire Study
AbbVie may terminate this study prematurely, either in its entirety or at any study site, for 
reasonable cause provided that written notice is submitted in advance of the intended 
termination.  The investigator may also terminate the study at his/her site for reasonable 
cause, after providing written notice to AbbVie in advance of the intended termination.  
Advance notice is not required by either party if the study is stopped due to safety 
concerns.  If AbbVie terminates the study for safety reasons, AbbVie will immediately 
notify the investigator by telephone and subsequently provide written instructions for 
study termination.

Treatments
5.5.1
Treatments Administered
Study drug will be taken orally QD, beginning on Day 1 (Baseline), and should be taken 
at approximately the same time each day.  The study drug can be taken with or without 
food.  Subjects will continue their stable background CD therapy, if allowed per protocol.  
AbbVie will not supply any background CD therapy taken during the course of the study.
Study drug may be shipped from the study site directly to the study subject's home if all of 
the following criteria are met:
●
Direct-to-patient (DTP) shipment of study drug is allowed by local regulations 
and the relevant ethics committee.
●
Subject agrees to have the study drug shipped directly to their home.
●
Shipments may also include other study supplies (e.g., paper copies of PROs, 
urine pregnancy tests).  Instructions will be provided by AbbVie as to how a 
study site can initiate a DTP shipment using Marken, a global vendor selected 
by AbbVie to provide this service when necessary.  Shipments of study drugs 
from the study site to a subject's home will be appropriately temperature 
controlled (qualified shipper or temperature monitoring) within the labeled 
storage conditions.  Signature is required upon delivery; due to pandemic-
related social distancing, this may be provided by the courier after delivery.  
Documentation of the shipment is to be retained by the clinical site. 
●
AbbVie will not receive subject identifying information related to these 
shipments as the site will work directly with the courier.
The study site is responsible for meeting IRB/IEC reporting requirements related to DTP 
shipments of study drug, and for obtaining consent to provide delivery information to the 
courier and documenting this consent in source documents.

Packaging and Labeling
Upadacitinib and matching placebo will be packaged in bottles with quantities sufficient 
to accommodate study design.  Each kit label will contain a unique kit number.  This kit 
number is assigned to a subject via interactive response technology (IRT) and encodes the 
appropriate study drug to be dispensed at the subject's corresponding study visit.  Each kit 
will be labeled as required per country requirements.  Labels must remain affixed to the 
kits.  All blank spaces on the label will be completed by the site staff prior to dispensing 
to the subjects.
5.5.2.2
Storage and Disposition of Study Drug(s)
Study drugs must be stored at controlled room temperature (15° to 25°C/59° to 77°F).  
The investigational products are for investigational use only and are to be used only 
within the context of this study.  The study drug supplied for this study must be 
maintained under adequate security and stored under the conditions specified on the label 
until dispensed for subject use or destroyed as appropriate.
5.5.3
Method of Assigning Subjects to Treatment Groups
All subjects will be assigned a unique identification number by the IRT at the Screening 
visit and will keep the same unique subject identification number throughout the study.  
Subjects who meet all of the inclusion criteria and none of the exclusion criteria defined in 
Section 5.2.1 and Section 5.2.2 will be centrally randomized.
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
106
The IRT will assign a randomization number that will encode the subject's treatment 
group assignment according to the randomization schedule generated by the Statistics 
Department at AbbVie.
IRT will provide the appropriate medication kit number(s) to dispense to each subject.  
Study drug will be administered at the study visits as summarized in Section 5.5.  
Returned study drug should not be re-dispensed to any subject.
In Part 1, subjects (n = 501) will be randomized in a 2:1 ratio to upadacitinib 45 mg QD or 
matching placebo for 12 weeks (Figure 1).  The randomization will be stratified by 
baseline corticosteroid use (yes or no), endoscopic disease severity (SES-CD < 15 and 
≥15) and number of prior biologics with prior inadequate response or intolerance (0, 1, 
> 1).
All subjects who do not achieve clinical response at Week 12 will be able to participate in 
Part 2 (Extended Treatment Period) to receive double-blind upadacitinib until 
Week 24/PD.
Part 2 is an Extended Treatment 12-week period consisting of 2 cohorts for subjects who 
do not achieve clinical response at Week 12 in Part 1.  The objectives of Part 2 are to offer 
blinded upadacitinib induction treatment to placebo non-responders from Part 1 and to 
evaluate a delayed clinical response to upadacitinib in subjects who did not initially 
respond to upadacitinib during Part 1.
●
Cohort 1:  Subjects who received placebo during Part 1 and did not achieve 
clinical response at Week 12 are eligible to receive double-blind induction 
treatment with upadacitinib 45 mg QD for 12 weeks (until Week 24).
●
Cohort 2:  Subjects who received upadacitinib during Part 1 and did not 
achieve clinical response at Week 12 are eligible to receive double-blind 
upadacitinib 30 mg QD for 12 weeks (until Week 24).
Subjects in Part 2 will remain blinded to treatment to avoid unmasking the treatment 
received during Part 1.
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
107
At Week 24, subjects who achieve clinical response may be eligible to enter 
Study M14-430.  Subjects are not eligible to enter Study M14-430 until the 
ileocolonoscopy procedure at Week 24 for evaluation of mucosal inflammation has been 
completed.  If the COVID-19 pandemic precludes a subject from undergoing an 
endoscopy, the subject can enroll in Study M14-430 if clinical response was achieved at 
Week 24.
Subjects who do not achieve clinical response at Week 24 will be discontinued from 
Study M14-433 and will receive standard of care treatment at the investigator's discretion.  
Subjects who do not achieve clinical response at Week 24 and all subjects who 
prematurely discontinue the study will have a follow-up visit 30 days from the last dose of 
study drug to collect information on new or ongoing AEs and laboratory assessments.
5.5.4
Selection and Timing of Dose for Each Subject
Subjects should take study drug as outlined in Section 5.5.1.
On dosing days that occur on study visit days, subjects should follow the regular dosing 
schedule (refer to Section 5.3.2.1 regarding Week 4 visit).
Each subject's dosing schedule should be closely monitored by the site at each study visit.  
This will ensure that all subjects enrolled into the study maintain their original dosing 
schedule beginning with the first dose of study drug (Baseline/Day 1).
If a subject should forget to take their upadacitinib (or matching placebo) dose at their 
regularly scheduled dosing time, they should take the forgotten dose as soon as they 
remember the dose was missed as long as it is at least 10 hours before their next scheduled 
dose.  If a subject only remembers the missed dose within 10 hours before next scheduled 
dose, the subject should skip the missed dose and take the next dose at the scheduled time.
For elective and emergency surgeries, the following rules apply:
●
If the subject must undergo emergency surgery, the study drug should be 
interrupted at the time of the surgery.  After emergency surgery, allow 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
108
reintroduction of study drug once the physician has examined the surgical site 
and determined that it has healed and there is no sign of infection.
●
Elective surgery will not be allowed during the study until the primary 
endpoint has been assessed.  If the subject undergoes elective surgery, the 
study drug should be interrupted 1 week prior to the planned surgery.  
Reintroduction of study drug is allowed once the physician has examined the 
surgical site and determined that it has healed and there is no sign of infection.
5.5.5
Blinding
All AbbVie personnel with direct oversight of the conduct and management of the trial 
(with the exception of AbbVie Drug Supply Management Team), the investigator, study 
site personnel, and the subject will remain blinded to each subject's treatment throughout 
the study and until that data is locked and analyzed as part of the planned analysis.  In 
order 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 medical emergency.
In the event of a medical situation 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 
EndPoint technical support via either phone (preferred) or email 
(support@endpointclinical.com).  For country-specific phone numbers, please see the 
following website:  http://www.endpointclinical.com/help-desk/.
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 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
109
and reason that the blind was broken must be conveyed to AbbVie and recorded on the 
appropriate eCRF.
5.5.5.1
Blinding of Investigational Product
In order to maintain the blind, the upadacitinib tablets and placebo tablets provided for the 
study will be identical in appearance.
5.5.5.2
Blinding of Data for Data Monitoring Committee (DMC)
An external DMC comprised of persons independent of AbbVie and with relevant 
expertise in their field will review unblinded safety data from the ongoing study.  The 
primary responsibility of the DMC will be to protect the safety of the subjects 
participating in this study.
A separate DMC charter will be prepared outside of the protocol and will describe the 
roles and responsibilities of the DMC members, frequency and triggers of data reviews, 
and relevant safety data to be assessed, and communication with and recommendations to 
AbbVie as well as relevant competent authorities, if necessary.
An independent committee of physician experts in cardiovascular adjudication will be 
utilized to assess cardiovascular AEs and embolic and thrombotic events (non-cardiac, 
non- central nervous system) in a blinded manner as defined by the cardiovascular 
adjudication committee (CAC) charter.
Communications from the DMC to the Study Teams and CAC will not contain 
information that could potentially unblind the team to subject treatment assignments.
5.5.6
Treatment Compliance
The investigator or his/her designated and qualified representatives will 
administer/dispense study drug only to subjects enrolled in the study in accordance with 
the protocol.  The study drug must not be used for reasons other than that described in the 
protocol.

Subjects will be instructed to return all drug containers (even if empty) to the study site 
personnel at each clinic visit.  The study site personnel will document compliance in the 
study source documents.
Subjects will be counseled on missed doses of study drug.  If the subject does not return 
the bottles (when applicable), the site should question the subject and obtain as much 
information as possible as to the dosing of the study drug.  The information should be 
documented on the source documents as per "best recollection" before completing on the 
applicable eCRF page.
5.5.7
Drug Accountability
The investigator or his/her representative will verify that study drug supplies are received 
intact and in the correct amounts.  This will be documented by signing and dating the 
Proof of Receipt or similar document and by registering the arrival of drug through the 
IRT.  The original Proof of Receipt Note and the IRT confirmation sheet will be kept in 
the site files as a record of what was received.
In addition, an IRT will be used to document investigational product accountability 
including but not limited to date received, the lot number, kit number(s), date dispensed, 
subject number, and the identification of the person dispensing the drug.
All empty/used study drug packaging will be inventoried by the site.  Empty/used study 
drug packaging should be returned by the subject at each visit for accountability and 
compliance purposes and new packaging issued as necessary.  
Site staff will complete study drug accountability via IRT, by using source documents and 
by visually inspecting the packaging whenever possible.  After drug accountability has 
been completed, used packaging and unused study drug will be destroyed on site 
according to local procedures or regulations or returned to the destruction depot (for those 
sites that do not meet AbbVie's documentation requirements for on-site destruction).  The 
use of a third party vendor for drug destruction must be pre-approved by AbbVie.  For 
sites performing on-site drug destruction or using a third party vendor for drug

destruction, a copy of the destruction methodology and date of destruction should be 
maintained at the site's facility.
During the COVID-19 or any pandemic, if a visit is completed virtually, study drug 
accountability can be conducted remotely with the subject.  Any kits that are accounted 
for remotely should be retained by the subject and when the subject is then able to 
complete an onsite visit, they should return all kits for verification of the drug 
accountability by the site staff.

Discussion and Justification of Study Design
5.6.1
Discussion of Study Design and Choice of Control Groups
Upadacitinib is a novel, orally administered JAK1 inhibitor being developed for the 
treatment of adult patients with inflammatory diseases and may provide improved clinical 
benefit to CD patients.  The proposed study is a Phase 3, randomized, double-blind, 
placebo-controlled induction study designed to evaluate the efficacy and safety of 
upadacitinib in adult subjects with a confirmed diagnosis of CD for at least 3 months and 
moderately to severely active CD who have inadequately responded to or are intolerant to 
conventional and/or biologic therapies.
This study will evaluate one induction dose of upadacitinib 45 mg QD.
In Part 1, approximately 501 subjects will be randomized in a 2:1 ratio to 45 mg 
upadacitinib QD or matching placebo for 12 weeks.  The randomization will be stratified 
by baseline corticosteroid use (yes or no), endoscopic disease severity (SES-CD < 15 and 
≥ 15) and number of prior biologics with prior inadequate response or intolerance (0, 1, 
> 1).  At this time, a 12-week placebo-controlled study is necessary for registrational 
purposes.  A comparative study utilizing placebo provides an unbiased assessment of the 
efficacy and safety profile of upadacitinib.  To ensure all subjects are given the 
opportunity to receive potentially efficacious therapy, all subjects not responding after 
12 weeks will be able to enroll in Part 2.
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
112
Part 2 is an Extended Treatment 12-week period consisting of 2 cohorts for subjects who 
do not achieve clinical response at Week 12 in Part 1.  The first objective of Part 2 is to 
offer blinded upadacitinib induction treatment to placebo non-responders from Part 1.  In 
the upadacitinib Phase 2 Study M13-740, subjects may achieve clinical remission after 
12 weeks with a lower upadacitinib dose.  This study will also evaluate delayed clinical 
response to upadacitinib in subjects who did not initially respond to upadacitinib 45 mg 
QD during Part 1.  In Part 2, these subjects will receive upadacitinib 30 mg QD for an 
additional 12 weeks.
The study was designed to enroll approximately 501 subjects to meet scientific and 
regulatory objectives, without enrolling an undue number of subjects in alignment with 
ethical considerations.  
5.6.2
Appropriateness of Measurements
Standard statistical, clinical, and laboratory procedures will be utilized in this study.  All 
efficacy measurements in this study are standard for assessing disease activity in subjects 
with CD.  All clinical and laboratory procedures in this study are standard and generally 
accepted.  Central reading of endoscopy will increase study rigor and ensure enrollment of 
patients with moderately to severely active CD.
5.6.3
Suitability of Subject Population
Adult male and female subjects between 18 to 75 years of age (or minimum age of adult 
consent according to local regulations) with moderately to severely active CD, who meet 
all of the inclusion criteria and none of the exclusion criteria, are eligible for enrollment in 
this study.  The specific population chosen was based on the unmet medical need of 
subjects with a history of inadequate response or intolerance to conventional therapies 
and/or biologic therapies.  
5.6.4
Selection of Doses in the Study
This study will evaluate one induction dose of upadacitinib (45 mg QD) (Figure 1).  The 
selection of this dose was informed by the analysis of the 16-week safety, efficacy and 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
113
exposure-response data of Phase 2 CD Study M13-740, which evaluated 5 induction 
doses of upadacitinib using the immediate-release formulation (3, 6, 12 or 24 mg BID or 
24 mg QD) versus placebo.  In addition, all of the currently available PK, 
pharmacodynamic, safety, and efficacy data from upadacitinib studies were used to 
support the selection of this dose.  The induction phase results from Study M13-740 
demonstrated the clinical and endoscopic efficacy of upadacitinib compared to placebo 
with doses of 6 mg BID and higher.
Upadacitinib dose of 45 mg QD using the once-daily formulation provides equivalent 
daily area under the concentration-time curve (AUC) and comparable maximum plasma 
concentration (Cmax) and minimum plasma concentration (Cmin) to 18 mg BID dose using 
the immediate-release formulation.  In the CD Phase 2 study, the dose of 12 mg BID and 
higher were shown to approach the plateau of efficacy for clinical endpoints while 
increasing the dose to 24 mg BID provided additional efficacy benefit particularly for the 
endoscopic endpoints.  Therefore, 45 mg QD regimen using the once-daily formulation 
(equivalent to 18 mg BID immediate-release) is predicted to provide the optimal balance 
between maximizing efficacy and limiting the effects on laboratory parameters 
(e.g., decreases in hemoglobin and NK cells).  Upadacitinib 45 mg QD, dosed for up to 
12 weeks is expected to be efficacious with an acceptable safety profile and upadacitinib 
15 mg QD and 30 mg QD, dosed for up to 240 weeks as maintenance treatment, are 
expected to be efficacious with acceptable safety profiles.

6.1
Medical Complaints
The investigator will monitor each subject for clinical and laboratory evidence of AEs on 
a routine basis throughout the study.  The investigator will assess and record any AE in 
detail including the date of onset, event diagnosis (if known) or sign/symptom, severity, 
time course (end date, ongoing, intermittent), relationship of the AE to study drug, and 
any action(s) taken.  For serious AEs considered as having "no reasonable possibility" of 
being associated with study drug, the investigator will provide an "Other" cause of the 
event.  For AEs to be considered intermittent, the events must be of similar nature and 
severity.  AEs, whether in response to a query, observed by site personnel, or reported 
spontaneously by the subject will be recorded.
All AEs will be followed to a satisfactory conclusion.
6.1.1
Definitions
6.1.1.1
Adverse Event
An AE is defined as any untoward medical occurrence in a patient or clinical investigation 
subject administered a pharmaceutical product and which does not necessarily have a 
causal relationship with this treatment.  An 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 accidental or intentional overdose, drug abuse, or drug withdrawal.  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, and/or if the investigator considers 
them to be AEs.
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
115
An elective surgery/procedure scheduled to occur during the study will not be considered 
an AE if the surgery/procedure is being performed for a pre-existing condition 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.
6.1.1.2
Serious Adverse Events
If an AE meets any of the following criteria, it is to be reported to AbbVie as a SAE 
within 24 hours of the site being made aware of the SAE.
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.
For SAEs with the outcome of death, the date and cause of death will be recorded on the 
appropriate eCRF.
6.1.1.3
Adverse Events of Special Interest
The following AEs of special interest will be monitored during the study (see detailed 
toxicity management in Section 6.1.7):
●
Serious infections;

6.1.2
Adverse Event Severity
When criteria are available, events should be graded as described in the National Cancer 
Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) 
version 4.03, which can be accessed at:  
http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm#ctc_40.
If no grading criteria are provided for the reported event, then the event should be graded 
as mild, moderate, or severe per the investigator's judgment.
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
Severe (Grade 3 - 5)
Grade 3
Grade 4
Grade 5
Severe or medically significant but not immediately life-
threatening; hospitalization or prolongation of 
hospitalization indicated; disabling; limiting self-care ADL
Life-threatening consequences; urgent intervention 
indicated.  
Death related to AE
Use the following guidelines when entering the severity grading criteria into the electronic 
data capture (EDC) system: Grade 1 as Mild; Grade 2 as Moderate; and Grade 3 to 5 as 
severe.

6.1.3
Relationship to Study Drug
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.
For causality assessments, events assessed as having a reasonable possibility of being 
related to the study drug will be considered "associated."  Events assessed as having no 
reasonable possibility of being related to study drug will be considered "not associated."  
In addition, when the investigator has not reported causality or deemed it not assessable, 
AbbVie will consider the event associated.
If an investigator's opinion of no reasonable possibility of being related to study drug is 
given, an "Other" cause of event must be provided by the investigator for the SAE.
6.1.4
Adverse Event Collection Period
All AEs reported from the time of study drug administration until 30 days following 
discontinuation of study drug administration have elapsed will be collected, whether 
solicited or spontaneously reported by the subject.  Subjects who discontinue study drug 
treatment but continue to participate in the study will have SAEs and nonserious AEs 
collected for the remainder of study participation.  In addition, SAEs and protocol-related 
nonserious AEs will be collected from the time the subject signed the study-specific 
informed consent.
AE information will be collected as shown in Figure 3.

Information regarding a pregnancy occurrence in a study subject and the outcome of the 
pregnancy will be collected.  
Pregnancy in a study subject is not considered an AE.  However, the medical 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.
6.1.7
Toxicity Management
The toxicity management of the AEs including AEs of special interest consists of safety 
monitoring (review of AEs on an ongoing basis, and periodical/ad hoc review of safety 
issues by a safety DMC), interruption of study drug dosing with appropriate clinical 
management if applicable, and discontinuation of the subjects from study drug.  The 
management of specific AEs and laboratory parameters is described below.
For subjects who discontinued study drug but continued study participation and are on 
standard of care therapies, these toxicity management requirements do not apply 
(including alerts from the central lab) and any intolerability to standard of care therapies 
should be managed by the prescribing physician.
Herpes zoster:  If a subject develops herpes zoster, consider temporarily interrupting 
study drug until the episode resolves.
Serious Infections:  Subjects should be closely monitored for the development of signs 
and symptoms of infection during and after treatment with study drug.  Study drug should 
be interrupted if a subject develops a serious infection.  A subject who develops a new 
infection during treatment with study drug should undergo prompt diagnostic testing 
appropriate for an immunocompromised subject.  As appropriate, antimicrobial therapy 
should be initiated, and the subject should be closely monitored.  Study drug may be 
resumed once the infection has been successfully treated.  Subjects who develop active 
TB must be discontinued from study drug.

Gastrointestinal Perforation:  Subjects presenting with the onset of signs or symptoms 
of a gastrointestinal perforation should be evaluated promptly for early diagnosis and 
treatment.  If the diagnosis of gastrointestinal perforation is confirmed, the subject must 
be discontinued from study drug.
Cardiovascular Events (MACE):  Subjects presenting with potential cardiovascular 
events should be appropriately assessed and carefully monitored.  These events will be 
reviewed and adjudicated by an independent CAC in a blinded manner.
Thrombosis Events:  Subjects who develop symptoms of thrombosis should be promptly 
evaluated and treated appropriately.  If the diagnosis of deep vein thrombosis, pulmonary 
embolus or noncardiac, nonneurologic arterial thrombosis is confirmed, the subject must
be 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 form must be completed.
Malignancy:  Subjects who develop malignancy or high grade colonic dysplasia, other 
than NMSC or carcinoma in situ of the cervix must be discontinued from study drug.  
Information including histopathological results should be queried for the confirmation of 
the diagnosis.  Periodic skin examination is recommended for subjects who are at 
increased risk for skin cancer.
ECG Abnormality:  Subjects must be discontinued from study drug for an ECG change 
considered clinically significant and with reasonable possibility of relationship to study 
drug.
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 5 and may 
require an appropriate supplemental eCRF to be completed.  All abnormal laboratory tests

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 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.

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.
o
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 > 8 × ULN by repeat testing with 
new sample.

Interrupt study drug if confirmed ALT or AST > 5 × ULN by repeat testing with 
new sample for more than 2 weeks.
For subjects with positive HBc Ab (irrespective of HBs Ab status) and negative 
HBV DNA at screening who develop the following laboratory findings should have 
HBV DNA by PCR testing should be performed within 1 week (based on initial 
elevated value):
o
ALT > 5 × ULN OR
o
ALT/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 in these subjects 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. The 
investigator should contact the AbbVie TA MD to discuss the management of a 
subject when an alternative etiology has been determined.  The alternative etiology 
should be documented appropriately in the eCRF; study drug should be discontinued 
if no alternative etiology can be found and ALT or AST elevations persist. If ALT or 
AST values return to the normal reference range or its Baseline value, study drug 
may be restarted. If restarting study drug, documentation should include reason 
rechallenge is expected to be safe.
For any confirmed ALT or AST elevations > 3 ULN, complete supplemental hepatic 
eCRF.

Statistical Methods and Determination of Sample 
Size
8.1
Statistical and Analytical Plans
The objective of the statistical analysis of Study M14-433 is to evaluate safety and 
efficacy of an upadacitinib 45-mg QD induction dose versus placebo in subjects with 
moderately and severely active CD.
The magnitude of missing data due to COVID-19 will be monitored and appropriate 
analysis to handle these missing data may be performed; details will be included in the 
SAP.  Further details of the statistical analysis will be described and documented in the 
Statistical Analysis Plan (SAP).
8.1.1
Datasets for Analysis
8.1.1.1
Intent to Treat Analysis Set
The intent-to-treat (ITT) analysis set includes all randomized subjects who have received
at least one dose of study drug in the double-blind induction period.  The ITT subjects 
will be analyzed as randomized.  The ITT set is the primary population for efficacy 
analysis.  All analyses of efficacy endpoints will be performed using the ITT analysis set.
8.1.1.2
Safety Analysis Set
The safety analysis set consists of all subjects who received at least one dose of the study 
drug.  Similarly, safety analysis set (Part 1) and safety analysis set (Part 2) consist of 
subjects who received at least one dose of the study drug, enrolled in Part 1 and Part 2, 
respectively.  The safety analysis set and safety analysis sets (Part 1 and Part 2) will be 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
130
analyzed as treated, according to treatment the subject actually received.  The safety 
analysis set and safety analysis sets (Part 1 and Part 2) will be used for safety analysis.
8.1.2
Definition of Missing Data Imputation
Missing data will be imputed using one or more of the following methods:
Non-Responder Imputation (NRI):  The NRI approach is used for binary efficacy 
variables.  These variables can take values of 'Achieved' or 'Not Achieved' or may be 
missing for any reason including discontinuation from study.  According to the NRI 
approach, all missing values will be considered as 'Not Achieved.'
Observed Cases (OC):  The OC analysis will not impute values for missing evaluations, 
and thus a subject who does not have an evaluation on a scheduled visit will be excluded 
from the OC analysis for that visit.
8.1.3
Subject Disposition
The number and percentage of subjects who are enrolled, randomized, and received at 
least one dose of study drug, the number of subjects who completed the study and the 
number of subjects who prematurely discontinued and the reason for premature 
discontinuation will be summarized by treatment group.  Premature discontinuation of 
study drug will be summarized for each treatment group, as well as for all subjects 
combined, with frequencies and percentages overall and by reason for discontinuation for 
all randomized subjects who received at least one dose of study drug.  Subjects may have 
multiple reasons for prematurely discontinuing study drug, but will be counted no more 
than once for the total ("Any Reason").
8.1.4
Demographics and Baseline Characteristics
Demographics and baseline characteristics of the study subjects will be summarized using 
descriptive statistics.  Summary statistics for continuous variables will include the number 
of observations, mean, standard deviation, median, and range for each treatment group.  
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
131
For other categorical or discrete variables, frequencies and percentages will be computed 
in each category for each treatment group, as well as for all subjects combined.  
8.1.5
Prior and Concomitant Medications
Prior therapy and medications will include all therapies and medications administered 
prior to the date of the first dose of study drug.  Prior therapy and medication will be 
summarized for the ITT analysis set.  No statistical test will be performed.
Concomitant medications will be summarized using the World Health Organization Drug 
Dictionary with frequencies and percentages for each treatment group.  No statistical test 
will be performed.
8.1.6
Efficacy Analysis
The co-primary and ranked secondary endpoints will be analyzed separately for EU/EMA 
and US/FDA regulatory purposes; these endpoints are specified in Section 5.5.3
separately for each set of analyses.
8.1.6.1
Primary Efficacy Variables
The co-primary endpoints are the proportion of subjects with clinical remission per PROs 
(EU/EMA) and per CDAI (US/FDA) at Week 12 and proportion of subjects with 
endoscopic response at Week 12 for the ITT population in Part 1.
The comparison between treatment groups on the co-primary efficacy endpoints will be 
performed using the Cochran-Mantel-Haenszel (CMH) test and will be stratified by 
Baseline corticosteroid use (yes or no), endoscopic disease severity (SES-CD < 15 and 
≥15) and number of prior biologics with prior inadequate response or intolerance (0, 1, 
> 1).  Both of the co-primary efficacy endpoints will be tested at two-sided significance 
level of 0.05.  A CMH based two-sided 95% confidence interval for the difference 
between treatment groups will be calculated.  If the average daily very soft or liquid SF or 
average daily AP score (EU/EMA) or CDAI (US/FDA) data at Week 12 are missing, the 
NRI approach will be applied for the clinical remission per PROs and clinical remission 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
132
per CDAI endpoints, respectively.  Subjects who discontinue prior to Week 12 for any 
reason will be considered as "not-achieved" for clinical remission or endoscopic response 
endpoints.
8.1.6.2
Secondary Efficacy Variables
A multiple testing procedure will be used to provide strong control of the type 1 error rate 
at alpha = 0.05 (2-sided) across analyses with respect to the co-primary endpoints, and 
ranked secondary endpoints as specified in Section 5.3.3. Specifically, testing will utilize 
a sequence of hypothesis testing for the co-primary endpoints followed by the ranked 
secondary endpoints, and will begin with testing co-primary endpoints using α of 0.05 
(2-sided). If both co-primary endpoints achieve statistical significance, continued testing 
will follow a pre-specified weight of α allocation between individual hypotheses as well 
as between families of hypotheses.  The details of the testing procedure will be specified 
and documented in the SAP.
In general, continuous secondary efficacy variables with repeated measurements will be 
analyzed using a Mixed Effect Repeated Measure (MMRM) model.  Continuous 
secondary efficacy variables which are collected at only one post-baseline visit (such as 
SES-CD) will be analyzed using an Analysis of Covariance (ANCOVA) model.
Categorical secondary efficacy variables will be analyzed using the CMH test controlling 
for stratification variables.  NRI for missing data will be used for categorical secondary 
endpoints.
8.1.7
Safety Analyses
Safety analyses will be performed on safety set and safety sets (Part 1 and Part 2), as 
defined in Section 8.1.1.2.  Incidence of AEs, changes in vital signs, physical examination 
results, and clinical laboratory data will be assessed throughout the study.  ECGs will be 
performed at screening and at the end of each Part 1 and Part 2 of the study.  AEs and 
laboratory data when available will be graded as described in the NCI CTCAE, and 
summarized accordingly.
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
133
AEs will be coded using the Medical Dictionary for Regulatory Activities (MedDRA).  
Treatment-emergent AEs are defined as events that begin or worsen either on or after the 
first dose of the study drug and within 30 days after the last dose of the study drug for 
subjects who do not participate in Study M14-430 or within 30 days after the last dose of 
the study drug in Study M14-433 or until first dose of study drug in Study M14-430 if the 
subject enrolls in Study M14-430, whichever comes first.  
An overview of treatment-emergent AEs, including AEs leading to death, AEs leading to 
premature discontinuation, AEs by MedDRA preferred term and system organ class, AEs 
by maximum relationship to study drug, AEs by maximum severity and AEs of special 
interest will be summarized by number and percentage.  
Changes from Baseline in continuous laboratory and vital sign parameters will be 
summarized by treatment group.  Treatment group differences between upadacitinib and 
placebo groups for changes from Baseline may be analyzed using a one-way ANOVA.  
Vital signs and laboratory data will be described by statistical characteristics and 
frequency of abnormal values.  In addition, shift tables and listings will be provided for 
abnormal values, whereby the normal range of the analyzing laboratory will be used.  
Analysis details will be specified in the SAP.
8.1.8
Pharmacokinetic and Exposure-Response Analyses
Individual upadacitinib plasma concentrations at each study visit will be tabulated and 
summarized with appropriate statistical methods.
Data from this study may be combined with data from other studies for the population PK 
and exposure-response analyses.  Population PK and exposure-response analyses of only 
data from this study may not be conducted.  The following general methodology will be 
used for the population PK and exposure-response analyses.
Population PK analyses will be performed using the actual sampling time relative to 
dosing.  PK models will be built using a non-linear mixed-effects modeling approach with 
NONMEM software (Version 7, or a higher version).  The structure of the starting PK
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
134
model will be based on the PK analysis of data from previous studies.  The CL/F and V/F 
of upadacitinib will be the PK parameters of major interest in the analyses.  If necessary, 
other parameters, including the parameters describing absorption characteristics, may be 
fixed if useful in the analysis.
The evaluation criteria described below will be used to examine the performance of 
different models.
1.
The objective function of the best model is significantly smaller than the alternative 
model(s).
2.
The observed and predicted concentrations from the preferred model are more 
randomly distributed across the line of unity (a straight line with zero intercept and 
a slope of one) than the alternative model(s).
3.
Visual inspection of model fits, standard errors of model parameters, and change in 
inter-subject and intra-subject error.
Once an appropriate base PK model (including inter- and intra-subject error structure) is 
developed, empirical Bayesian estimates of individual model parameters will be 
calculated by the posterior conditional estimation technique using non-linear mixed-
effects modeling.  The relationship between these conditional estimates CL/F and V/F 
values with only potentially physiologically relevant or clinically meaningful covariates 
(such as subject age, sex, body weight, concomitant medications, laboratory markers of 
hepatic of renal function, etc.) will be explored using stepwise forward selection method, 
or another suitable regression/smoothing method at a significance level of 0.05.  After 
identification of all relevant covariates, a stepwise backward elimination of covariates 
from the full model will be employed to evaluate the significance (at P < 0.005, 
corresponding to a decrease in objective function > 7.88 for one degree of freedom) of 
each covariate in the full model.
Linear or non-linear relationships of primary PK parameters with various covariates will 
be explored.
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
135
Relationships between upadacitinib exposure and clinical observations (primary efficacy 
variable) will be explored.  Exposure-response relationships for efficacy variables and/or 
some safety measures of interest may also be explored.  The relationship between 
exposure (e.g., population PK model predicted average concentrations, AUC, trough 
concentrations, the individual model-predicted PK profiles, or some other appropriate 
measure of exposure) and drug effect will be explored.  Several classes of models (e.g., 
linear, log-linear, exponential, maximum effect [Emax], sigmoid Emax, etc.) will be 
evaluated to characterize the exposure-response relationship based on observed data.  
Results of the PK and exposure-response analyses may be summarized in a separate report 
prior to regulatory filing of upadacitinib for the treatment of CD, rather than in the CSR.
Additional analyses will be performed if useful and appropriate.
8.2
Determination of Sample Size
The co-primary endpoints are the proportion of subjects with clinical remission per PROs 
(EU/EMA) and per CDAI (US/FDA) at Week 12 and the proportion of subjects who 
achieve endoscopic response at Week 12.
Sample size calculation is based on the maximum sample size needed to detect treatment 
difference for each of the co-primary endpoints.  The proposed assumptions were 
informed by the results of the 16-week clinical and endoscopic data of upadacitinib 
Phase 2 CD Study M13-740 and available published data with another investigational 
JAK1 inhibitor.  
For EU/EMA regulatory purposes:  Assuming a clinical remission rate of 15% in the 
placebo group and 33% in the upadacitinib group at Week 12, a total sample size of 
501 subjects randomized in a 2:1 ratio (334 subjects in the upadacitinib group and 
167 subjects in the placebo group) will be adequate to detect at least a 18% treatment 
difference in clinical remission rates at Week 12 between the treatment groups using 
Fisher's exact test with at least 95% power at a 0.05 two-sided significant level.  
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
136
For US/FDA regulatory purposes:  Assuming a clinical remission per CDAI rate of 21.5% 
in the placebo group and 45% in the upadacitinib group at Week 12, this sample size will 
be adequate to detect at least a 23.5% treatment difference in clinical remission rates at 
Week 12 between the treatment groups using Fisher's exact test with at least 95% power 
at a 0.05 two-sided significant level.  
Assuming an endoscopic response rate of 11.5% in the placebo group and 28.5% in the 
upadacitinib group at Week 12, this sample size will be adequate to detect at least a 17% 
treatment difference in endoscopic response rates at Week 12 between the treatment 
groups using Fisher's exact test with at least 95% power at a 0.05 two-sided significant 
level.  
8.3
Randomization Methods
Approximately 501 subjects will be randomized in Part 1 in a 2:1 ratio into upadacitinib 
45 mg group or matching placebo (334 subjects for upadacitinib 45 mg QD dose group 
and 167 subjects for placebo group).  Randomization will be stratified by baseline 
corticosteroid use (yes or no), endoscopic disease severity (SES-CD < 15 and ≥ 15) and 
number of prior biologics with prior inadequate response or intolerance (0, 1, > 1).
Subjects enrolling in Part 2 from Part 1 are assigned either upadacitinib 45 mg QD or 
upadacitinib 30 mg QD depending on the randomized treatment received in Part 1 
(placebo or upadacitinib 45 mg) in a blinded fashion.
9.0
Ethics
9.1

Board (IRB)
Good Clinical Practice (GCP) requires that the clinical protocol, any protocol 
amendments, the Investigator's Brochure, the informed consent and all other forms of 
subject information related to the study (e.g., advertisements used to recruit subjects) and 
any other necessary documents be reviewed by an IEC/IRB.  The IEC/IRB will review the 
ethical, scientific and medical appropriateness of the study before it is conducted.  
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
137
IEC/IRB approval of the protocol, informed consent and subject information and/or 
advertising, as relevant, will be obtained prior to the authorization of drug shipment to a 
study site.
Any amendments to the protocol will require IEC/IRB approval prior to implementation
of any changes made to the study design.  The investigator will be required to submit, 
maintain and archive study essential documents according to International Council for 
Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) 
GCP and all other applicable regulatory requirements.
Any SAEs that meet the reporting criteria, as dictated by local regulations, will be 
reported to both responsible Ethics Committees and Regulatory Agencies, as required by 
local regulations.  During the conduct of the study, the investigator should promptly 
provide written reports (e.g., ICH Expedited Reports, and any additional reports required 
by local regulations) to the IEC/IRB of any changes that affect the conduct of the study 
and/or increase the risk to subjects.  Written documentation of the submission to the 
IEC/IRB should also be provided to AbbVie.
9.2
Ethical Conduct of the Study
The study will be conducted in accordance with the protocol, 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 clinical 
investigator are specified in Appendix A.
In the event a state of emergency due to the COVID-19 or any pandemic leads 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., phone 
contacts or virtual site visits), alternative locations for data collection (e.g., use of a local 
laboratory instead of a central laboratory), and shipping investigational product and/or 
 


Upadacitinib (ABT-494)

supplies DTP to ensure continuity of treatment where allowed.  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.
9.3
Subject Information and Consent
The investigator or his/her representative will explain the nature of the study to the 
subject, and answer all questions regarding this study.  Prior to any study-related 
screening procedures being performed on the subject, the informed consent statement will 
be reviewed and signed and dated by the subject, the person who administered the 
informed consent, and any other signatories according to local requirements.  A copy of 
the informed consent will be given to the subject and the original will be placed in the 
subject's medical record.  An entry must also be made in the subject's dated source 
documents to confirm that informed consent was obtained prior to any study-related 
procedures and that the subject received a signed copy.
Information regarding incentives for subjects and information regarding provisions for 
treating and/or compensating subjects who are harmed as a consequence of participation 
in the study can be found in the informed consent.
Samples for exploratory research will only be collected and tested after the subject has 
voluntarily signed and dated the separate written consent for exploratory research, 
approved by an IRB/IEC, after the nature of the testing has been explained and the subject 
has had an opportunity to ask questions.  The separate written consent may be part of the 
main consent form.  If the subject does not consent to the exploratory research, it will not 
impact the subject's participation in the study.
In the event a subject withdraws from the main study, optional exploratory research 
samples will continue to be stored and analyzed unless the subject specifically withdraws 
consent for the optional samples.  If consent is withdrawn for the optional sampling, the 
subject must inform their study doctor, and once AbbVie is informed, the optional 
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
139
samples will be destroyed.  However, if the subject withdraws his/her consent and the 
samples have already been tested, those results will still remain as part of the overall 
research data.
9.3.1
Informed Consent Form and Explanatory Material
In Japan, the principal investigator will prepare the consent form and explanatory material 
required to obtain subject's consent to participate in the study with the cooperation of the 
sponsor and will revise these documents as required.  The prepared or revised consent 
forms and explanatory material will be submitted to the sponsor.  Approval of the IRB 
will be obtained prior to use in the study.
9.3.2
Revision of the Consent Form and Explanatory Material
In Japan, when important new information related to the subject's consent becomes 
available, the principal investigator will revise the consent form and explanatory material 
based on the information without delay and will obtain the approval of the IRB prior to 
use in the study.  The investigator will provide the information, without delay, to each 
subject already participating in the study, and will confirm the intention of each subject to 
continue the study or not.  The investigator shall also provide a further explanation using 
the revised form and explanatory material and shall obtain written consent from each 
subject of their own free will to continue participating in the study.

The investigator(s)/institution(s) will permit study-related monitoring, audits, IEC/IRB 
review, and regulatory inspection(s), providing direct access to source data documents.
During the COVID-19 or any pandemic, remote monitoring of data may be employed if 
allowed by the local regulatory authority, IRB/IEC, and the study site.
10.2
Electronic Case Report Forms (eCRF)
eCRFs must be completed for each subject screened/enrolled in this study.  These forms 
will be used to transmit information collected during the study to AbbVie and regulatory 
authorities, as applicable.  The CRF data for this study are being collected with an EDC 
system called Rave® provided by the technology vendor Medidata Solutions Incorporated, 
NY, USA.  The EDC system and the study-specific eCRFs will comply with Title 21 CFR 
Part 11.  The documentation related to the validation of the EDC system is available 
through the vendor, Medidata, while the validation of the study-specific eCRFs will be 
conducted by AbbVie and will be maintained in the Trial Master File at AbbVie.
The investigator will document subject data in his/her own subject files.  These subject 
files will serve as source data for the study.  All eCRF data required by this protocol will 
be recorded by investigative site personnel in the EDC system.  All data entered into the 
eCRF will be supported by source documentation.
The investigator or an authorized member of the Investigator's staff will make any 
necessary corrections to the eCRF.  All change information, including the date and person 
performing the corrections, will be available via the audit trail, which is part of the EDC 
system.  For any correction, a reason for the alteration will be provided.  The eCRFs will 
be reviewed periodically for completeness, legibility, and acceptability by AbbVie 
personnel (or their representatives).  AbbVie (or their representatives) will also be allowed

EudraCT 2017-001240-35
141
principal investigator will review the eCRFs for completeness and accuracy and provide 
his or her electronic signature and date to eCRFs as evidence thereof.
Medidata will provide access to the EDC system for the duration of the trial through a 
password-protected method of internet access.  Such access will be removed from 
investigator sites at the end of the site's participation in the study.  Data from the EDC 
system will be archived on appropriate data media (CD-ROM, etc.) and provided to the 
investigator at that time as a durable record of the site's eCRF data.  It will be possible for 
the investigator to make paper printouts from that media.
10.3
Electronic Patient Reported Outcomes (ePRO)
Patient reported data must be completed for each subject screened/enrolled in this study.  
Some of these data are being collected with an Electronic Patient Reported Outcome 
(ePRO) system called Trialmax, provided by the technology vendor CRF Health of 
Plymouth Meeting, PA, USA.  The ePRO system is in compliance with Title 21 CFR 
Part 11.  The documentation related to the system validation of the ePRO system is 
available through the vendor, CRF Health, while the user acceptance testing of the study-
specific PRO design will be conducted and maintained at AbbVie.
The subject will be entering the data on two electronic devices; these data will be 
uploaded to a server.  The data on the server will be considered source, and maintained 
and managed by CRF Health.
Internet access to the ePRO data will be provided by CRF Health for the duration of the 
study.  This access will be available for the duration of the study to the site investigator, as 
well as delegated personnel.  Such access will be removed from investigator sites 
following the receipt of the study archive.  Data from the ePRO system will be archived 
on appropriate data media (CD-ROM, etc.) and provided to the investigator at that time as 
a durable record of the site's ePRO data.  It will be possible for the investigator to make 
paper print-outs from that media.
The ePRO data will be collected by the following methods:
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
142
Diary Based
The ePRO data (number of total and liquid or very soft stools, stool consistency per 
Bristol Stool Chart, use of medications used for endoscopy preparation, if an endoscopy 
was performed, AP, and general well-being) will be collected electronically via a 
handheld device into which the subject will record the required pieces of information on a 
daily basis.  The electronic device will be programmed to allow data entry once per day.  
All data entered on the device will be immediately stored to the device itself and 
manually/automatically uploaded to a central server administrated by CRF Health.  The 
investigational site staff will be able to access all uploaded subject entered data via a 
password protected website, up until the generation, receipt and confirmation of the study 
archive.
Tablet Based
The ePRO data (IBDQ, CSS, EQ-5D-5L, WPAI-CD, SF-36, FACIT-F, PGI-S, and PGIC) 
will be collected electronically via an onsite device at visits specified in Appendix C.  The 
electronic device will be programmed to allow data entry once per day per study subject.  
All data entered on the device will be immediately stored to the device itself and 
manually/automatically uploaded to a central server administrated by CRF Health.  The 
investigator and delegated staff, will be able to access all uploaded patient entered data via 
a password protected website, up until the generation, receipt and confirmation of the 
study archive.
Due to the COVID-19 or any pandemic, subject visits may be conducted via phone or 
video conference.  PROs are eligible for completion by interview at the visits specified in 
Appendix C.  In this situation, sites will read the PRO questions and response options to 
the subject and record the subject's responses.  The subjects' ability to view the PRO to 
understand the questions and response options should be preserved.  Sites may share the 
questionnaire by videoconference or send the questionnaires (email or hard copy) to the 
subjects to allow them to read/understand the questions and responses when the subject is

recorded along with the name of the person who collected the information.
11.0
Data Quality Assurance
To ensure data integrity and subject safety, a study monitor will, throughout the study, 
verify that all subjects signed agreement of informed consent prior to any study-specific 
procedures being conducted.  The study monitor will confirm that the investigator is 
conducting the study in compliance with the protocol, GCP and applicable regulations, 
and verify that the information reported in the eCRF is complete, accurate, and supported 
by information in source documents.
Computer logic and manual checks will be created to identify items such as inconsistent 
study dates.  Any necessary corrections will be made to the eCRF.
12.0
Use of Information
All information concerning upadacitinib and AbbVie operations, such as AbbVie patent 
applications, formulas, manufacturing processes, basic scientific data, or formulation 
information, supplied by AbbVie and not previously published is considered confidential 
information.

a.
The Screening Period will be a minimum of 8 days but no more than 35 days prior to the Baseline visit.  Baseline Visit date will serve as the reference for all subsequent 
visits.  A ± 3-day window is permitted around scheduled study visits.
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
157
b.
Visits to retest a lab will not be considered an unscheduled visit.  Unscheduled visits according to this table are for purposes when the subject is coming in for a visit for 
evaluation and assessment.
c.
Update inclusion/exclusion, prior and concomitant therapy, and medical/surgical history information to assure subject eligibility.  All subjects need to have their average daily 
very soft or liquid SF and average daily AP score calculated and meeting eligibility criteria before randomization at Baseline.
d.
Physical examinations are full physical examinations performed at Screening, Baseline and Week 12, and Week 24/PD if the subject undergoes Part 2.  Physical examinations 
at all other visits are symptom-based but should include an assessment of EIMs and presence or absence of cutaneous fistulas, as part of calculating the CDAI.  During the full 
physical examination, all subjects will be assessed for presence and number of draining and non-draining enterocutaneous (perianal and abdominal) and rectovaginal fistulas 
at Baseline, Week 12, and Week 24/PD.  If the assessment of presence and number of draining and non-draining fistulas were performed during Screening or the visit for 
endoscopy, this may be used for the respective Baseline, Week 12, or Week 24/PD visits.  
e.
Blood pressure, pulse rate, temperature, respiratory rate and weight should be performed before blood draws are performed.  Height will be measured at Screening only (with 
shoes off).
f.
Ileocolonoscopies will be used to calculate the SES-CD.  The Screening ileocolonoscopy should be done during the Screening period or within 45 days of the Baseline Visit, 
if video recorded.  Endoscopic evaluations using SES-CD confirmed by central reader will be done at Screening.  Patients who complete at least 8 weeks in Part 1 or at least 
20 weeks in Part 2 will be required to have an endoscopy. Where COVID-19 or any pandemic affects Week 12 or Week 24 endoscopy, a ± 7 day window is permitted.
g.
Biopsy may be done when performing the endoscopy.  At Screening, biopsy to confirm CD diagnosis must be done when performing the endoscopy if appropriate 
documentation for confirmation of the diagnosis does not exist.  Biopsies to rule out dysplasia and colon cancer may be taken at the investigator's discretion.  Optional 
intestinal biopsy samples for histopathology and biological investigations, including but not limited to, transcriptomic analyses and immunohistochemistry may be evaluated 
in approximately 200 subjects (intestinal biopsy substudy).
h.
Subjects with normal ECG within 90 days of Screening would not require a repeat ECG, if documentation is available.  Subjects can have a repeat ECG at any time during the 
study as warranted based on the opinion of the investigator.
i.
PPD skin test is to be read 48 to 72 hours after placement.  Subjects with negative QuantiFERON TB Gold test and/or PPD test within 90 days of Screening will not require a 
repeat test (documentation must be available).  In case of positive PPD/positive or repeat indeterminate IGRA testing, in the absence of active TB, the subject may participate 
in the study after initiation of latent TB treatment (regimen according to local practice/guidelines).
j.
Chest x-ray includes posterior-anterior view and lateral view.  Subjects can have a chest x-ray anytime during the study as warranted based on the opinion of the investigator.  
In Japan and China, a CT scan of the chest may be performed in lieu of a chest x-ray, at the investigator's discretion.
k.
FSH should be tested at Screening if the female subject is ≤ 55 years of age AND has had no menses ≥ 12 months AND has no history of permanent surgical sterilization 
(Refer to Section 5.2.4).
 


Upadacitinib (ABT-494)

l.
Subjects will be tested for the presence of HBV and HCV at Screening.  A positive result for HBs Ag or hepatitis C (HCV RNA detectable in any subject with anti-HCV Ab) 
will be exclusionary.  For subjects who are negative for both HBs Ag and HBs Ab but are positive for HBc Ab, HBV DNA PCR will be performed and any result that meets 
or exceeds detection sensitivity will be exclusionary.  HIV testing will be performed at the central laboratory, unless prohibited by local regulations.  The central lab will 
report the HIV test results directly to the sites.  AbbVie will not receive results from the HIV testing and not be made aware of any positive result.
m.
For Japan or countries who mandate periodic screening for HBV:  subjects with positive HBs Ab and/or positive HBc Ab and a negative HBV DNA PCR test result at 
Screening, should have HBV DNA PCR test performed at 12 and 24 weeks; in cases where recurrence of HBV DNA is observed, the subject should be discontinued from the 
study.  This measure is not necessary in patients with history of HBV vaccination and positive HBs Ab result.
n.
Laboratory tests performed during the Screening period can be repeated in case the abnormalities are considered to be transient by the investigator.
o.
Minimum 8-hour fast for chemistry.  If a subject is not able to fast, the non-fasting status will be recorded in study source documentation.  Urinalysis, chemistry and 
hematology may be collected at other scheduled and unscheduled visits than indicated in the table in case of repeat test for toxicity management criteria or if they are 
warranted by the investigator.
p.
Urinalysis will be completed by the central lab at the required visits.  A microscopic analysis will be performed in the event the dipstick results show leukocytes, nitrite, 
protein, ketones, or blood greater than negative or glucose greater than normal.
q.
Serum pregnancy test will be performed on all women of childbearing potential at Screening.  Urine pregnancy test will be performed locally at the Baseline Visit prior to the 
first dose of study drug and at all subsequent visits, including the 30-day follow-up visit for all women of childbearing potential (refer to Section 5.2.4).  If any urine 
pregnancy test is positive, a serum pregnancy test will be performed by the central laboratory.  If serum pregnancy test comes back borderline, a repeat test is necessary 
(pregnancy is an exclusion criterion).  If still borderline ≥ 3 days later, this will be considered documentation of continued lack of a positive result and the subject can be 
enrolled into the study in absence of clinical suspicion of pregnancy or other pathological cause of borderline result.  If a pregnancy is identified, the pregnancy must be 
reported to AbbVie.
r.
At the Week 4 visit, PK samples should be collected prior to dosing if possible and the subjects should take the study drug dose at the clinic after collecting the PK blood 
sample.  However, if the subject normally takes the study drug dose at a time that is after the time of the scheduled study visit, the subject should follow the regular dosing 
schedule and the PK sample should be collected at any time during the visit.  For all other visits, PK samples should be collected at any time during the visit and the subject 
should follow the regular dosing schedule.
s.
A stool sample will be collected at each time point indicated for FCP.  For the visit that endoscopy will be conducted, stool sample should be collected prior to bowel prep.  
Subjects will be asked to provide a stool sample at the visit, if possible, or the site will give instructions and a stool sample supply kit.
t.
Diary information collected during Screening will serve to calculate Baseline CDAI.
u.
Collection of SAEs begins the day the subject signs the informed consent form.

Patient Reported Outcomes Descriptions
IBDQ – Inflammatory Bowel Disease Questionnaire
The IBDQ is a disease-specific instrument composed of 32 Likert-scaled items.  The total 
score ranges from 32 to 224 using the 7-point response options, with higher scores 
indicating better health-related quality of life.  The IBDQ scale contains 4 component 
subscales:  bowel symptoms, systemic symptoms, emotional function, and social function.  
Each subscale can be computed with total scores ranging from 10 – 70, 5 to 35, 12 to 84, 
and 5 to 35, respectively.27,28
WPAI-CD – Work Productivity and Activity Impairment Questionnaire-Crohn's 
Disease
The Work Productivity and Activity Index assesses the impact of the condition on work
productivity losses and impairment in daily activity.  WPAI has six items covering 
four domains:  Absenteeism (work time missed), measured as the number of hours missed 
from work in the past 7 days due to a condition related problems.  Scores are expressed as 
impairment percentages, adjusting for hours actually worked according to the WPAI 
scoring algorithm; Presenteeism (impairment at work/reduced on-the-job effectiveness), 
measured as the impact of the condition on productivity while at work (i.e., reduced 
amount or kind of work, or not as focused as usual).  Responses are recorded on a 0 – 10 
Likert scale (where, 0 = no effect of CD on work and 10 = severe impact of CD while at 
work); productivity loss (overall work impairment), measured as the sum of hours missed 
due to condition i.e., absenteeism and number of hours worked with impairment 
i.e., product of number of hours worked and presenteeism; and activity impairment 
(i.e., activities other than paid work like work around house, cleaning, shopping, traveling, 
studying), recorded and scored in same way as presenteeism.  Higher numbers indicate 
greater impairment and less productivity.29
CSS – Crohn's Symptoms Severity Questionnaire
The CSS questionnaire is a 14-item assessment of both GI and non-GI CD symptoms 
using a 7-day recall period.  The 14 items assess the frequency or intensity of each

162
individual symptom by utilizing a 5-point Likert-type scale.  An assessment of an 
individual items frequency and intensity is measured as follows: 
●
Frequency:  1 = Never, 2 = Rarely, 3 = Sometimes; 4 = Often, 5 = Always
●
Intensity:  1 = Not at all, 2 = A little bit; 3 = Somewhat; 4 = Quite a bit; 
5 = Very much
An overall symptom score is calculated by combining ratings from the 14 individual items 
(possible scores range from 14 to 70) with higher scores indicating greater symptom 
frequency or intensity. 
SF-36 – Short Form 36
The SF-36 questionnaire is a self-administered multi-domain scale with 36 items.  
Eight subscales cover a range of functioning:  physical functioning, role-physical, bodily 
pain, general health, vitality, social functioning, role-emotional, and mental health.  The 
scoring yields a physical component score, a mental component summary score, and 
subscale scores.  Higher scores represent better outcomes.  The concepts measured by the 
SF-36 are not specific to any age, disease, or treatment group, allowing comparison of 
relative burden of different diseases and the benefit of different treatments.30,31
EQ-5D – European Quality of Life 5 Dimensions
The EQ-5D-5L is a standardized non-disease specific instrument for describing and 
valuing health-related quality of life.  The EQ-5D consists of 5 dimensions:  mobility, 
self-care, usual activity, pain/discomfort, and anxiety/depression.  Each dimension has 
5 levels:  no problem, slight problem, moderate problem, severe problem or unable to do 
the activity.  It also contains a Visual Analogue Scale (VAS).  Subjects are asked to 
indicate the level that describes their current level of function or experience for each 
dimension.  As a measure of health status, it provides a descriptive profile and can be used 
to generate a single index value for health status, where full health is equal to 1 and death 
is equal to 0.  The VAS records the subject's assessment of his/her own health along a 
vertical 20 cm line, which has health state scores between 0 and 100.32

FACIT-F – Functional Assessment of Chronic Illness Therapy-Fatigue
The Functional Assessment of Chronic Illness Therapy system is a collection of quality of 
life (QoL) questionnaires targeted to the management of cancer and other chronic 
illnesses.  The FACIT-F questionnaire was developed to assess fatigue associated with 
anemia.  It consists of 13 fatigue-related questions.  The responses to the 13 items on the 
FACIT fatigue questionnaire are each measured on a 4-point Likert scale.  The responses 
to the answers are the following:  (i) not at all:  0 points; (ii) a little bit:  1 point; 
(iii) somewhat:  2 points; (iv) quite a bit:  3 points; (v) very much:  4 points.  Thus, the 
total score ranges from 0 to 52.  High scores represent less fatigue.33
PGIC – Patient Global Impression of Change
The PGIC is a self-administered instrument that assesses change in the overall symptoms 
due to Crohn's disease.  The PGIC is one item in which subjects are asked to rate overall 
improvement since start of the treatment.  Subjects rate their change as "Very much 
improved," "Much improved," "Minimally improved," "No change," "Minimally worse," 
"Much worse" and "Very much worse."
PGI-S – Patient Global Impression of Severity
The PGI-S is a self-administered instrument that assesses the severity of the overall 
symptoms due to Crohn's disease.  The PGI-S is one item in which subjects are asked to 
rate overall severity of symptoms over the past week.  Subjects rate their change as 
"Absent," "Minimal," "Mild," "Moderate," "Moderately severe," "Severe" and "Very 
severe."
HCRU – Health Care Resource Use
Health Care Resource use data on number of Hospitalization and surgeries will be 
collected through subject Administration module SAE supplemental Page.

subjects to allow them to read/understand the questions and responses when the subject is 
providing responses over the phone.  The date and time of PRO data collection should be 
recorded along with the name of the person who collected the information.

a.
The Screening Period will be a minimum of 8 days but no more than 35 days prior to the Baseline visit.  Baseline Visit date will serve as the reference for all subsequent 
visits.  A ± 3-day window is permitted around scheduled study visits.
 


Upadacitinib (ABT-494)

193
b.
Visits to retest a lab will not be considered an unscheduled visit.  Unscheduled visits according to this table are for purposes when the subject is coming in for a visit for 
evaluation and assessment.
c.
Update inclusion/exclusion, prior and concomitant therapy, and medical/surgical history information to assure subject eligibility.  All subjects need to have their average daily 
very soft or liquid SF and average daily AP score calculated and meeting eligibility criteria before randomization at Baseline.
d.
Physical examinations are full physical examinations performed at Screening, Baseline and Week 12, and Week 24/PD if the subject undergoes Part 2.  Physical examinations 
at all other visits are symptom-based but should include an assessment of EIMs and presence or absence of cutaneous fistulas, as part of calculating the CDAI.  During the full 
physical examination, all subjects will be assessed for presence and number of draining and non-draining enterocutaneous (perianal and abdominal) and rectovaginal fistulas 
at Baseline, Week 12, and Week 24/PD.  If the assessment of presence and number of draining and non-draining fistulas were performed during Screening or the visit for 
endoscopy, this may be used for the respective Baseline, Week 12, or Week 24/PD visits.  
e.
Blood pressure, pulse rate, temperature, respiratory rate and weight should be performed before blood draws are performed.  Height will be measured at Screening only (with 
shoes off).
f.
Ileocolonoscopies will be used to calculate the SES-CD.  The Screening ileocolonoscopy should be done during the Screening period or within 45 days of the Baseline Visit, 
if video recorded.  Endoscopic evaluations using SES-CD confirmed by central reader will be done at Screening.  Patients who complete at least 8 weeks in Part 1 or at least 
20 weeks in Part 2 will be required to have an endoscopy.
g.
Biopsy may be done when performing the endoscopy.  At Screening, biopsy to confirm CD diagnosis must be done when performing the endoscopy if appropriate 
documentation for confirmation of the diagnosis does not exist.  Biopsies to rule out dysplasia and colon cancer may be taken at the investigator's discretion.  Optional 
intestinal biopsy samples for histopathology and biological investigations, including but not limited to, transcriptomic analyses and immunohistochemistry may be evaluated 
in approximately 200 subjects (intestinal biopsy substudy).
h.
Subjects with normal ECG within 90 days of Screening would not require a repeat ECG, if documentation is available.  Subjects can have a repeat ECG at any time during the 
study as warranted based on the opinion of the investigator.
i.
PPD skin test is to be read 48 to 72 hours after placement.  Subjects with negative QuantiFERON TB Gold test and/or PPD test within 90 days of Screening will not require a 
repeat test (documentation must be available).  In case of positive PPD/positive or repeat indeterminate IGRA testing, in the absence of active TB, the subject may participate 
in the study after initiation of latent TB treatment (regimen according to local practice/guidelines).
j.
Chest x-ray includes posterior-anterior view and lateral view.  Subjects can have a chest x-ray anytime during the study as warranted based on the opinion of the investigator.  
In Japan and China, a CT scan of the chest may be performed in lieu of a chest x-ray, at the investigator's discretion.
k.
FSH should be tested at Screening if the female subject is ≤ 55 years of age AND has had no menses ≥ 12 months AND has no history of permanent surgical sterilization 
(Refer to Section 5.2.4).
 


Upadacitinib (ABT-494)
M14-433 Protocol Amendment 6
EudraCT 2017-001240-35
194
l.
Subjects will be tested for the presence of HBV and HCV at Screening.  A positive result for HBs Ag or hepatitis C (HCV RNA detectable in any subject with anti-HCV Ab) 
will be exclusionary.  For subjects who are negative for both HBs Ag and HBs Ab but are positive for HBc Ab, HBV DNA PCR will be performed and any result that meets 
or exceeds detection sensitivity will be exclusionary.  HIV testing will be performed at the central laboratory, unless prohibited by local regulations.  The central lab will 
report the HIV test results directly to the sites.  AbbVie will not receive results from the HIV testing and not be made aware of any positive result.
m.
For Japan or countries who mandate periodic screening for HBV:  subjects with positive HBs Ab and/or positive HBc Ab and a negative HBV DNA PCR test result at 
Screening, should have HBV DNA PCR test performed at 12 and 24 weeks; in cases where recurrence of HBV DNA is observed, the subject should be discontinued from the 
study.  This measure is not necessary in patients with history of HBV vaccination and positive HBs Ab result.
n.
Laboratory tests performed during the Screening period can be repeated in case the abnormalities are considered to be transient by the investigator.
o.
Minimum 8-hour fast for chemistry.  If a subject is not able to fast, the non-fasting status will be recorded in study source documentation.  Urinalysis, chemistry and 
hematology may be collected at other scheduled and unscheduled visits than indicated in the table in case of repeat test for toxicity management criteria or if they are 
warranted by the investigator.
p.
Urinalysis will be completed by the central lab at the required visits.  A microscopic analysis will be performed in the event the dipstick results show leukocytes, nitrite, 
protein, ketones, or blood greater than negative or glucose greater than normal.
q.
Serum pregnancy test will be performed on all women of childbearing potential at Screening.  Urine pregnancy test will be performed locally at the Baseline Visit prior to the 
first dose of study drug and at all subsequent visits, including the 30-day follow-up visit for all women of childbearing potential (refer to Section 5.2.4).  If any urine 
pregnancy test is positive, a serum pregnancy test will be performed by the central laboratory.  If serum pregnancy test comes back borderline, a repeat test is necessary 
(pregnancy is an exclusion criterion).  If still borderline ≥ 3 days later, this will be considered documentation of continued lack of a positive result and the subject can be 
enrolled into the study in absence of clinical suspicion of pregnancy or other pathological cause of borderline result.  If a pregnancy is identified, the pregnancy must be 
reported to AbbVie.
r.
At the Week 4 visit, PK samples should be collected prior to dosing if possible and the subjects should take the study drug dose at the clinic after collecting the PK blood 
sample.  However, if the subject normally takes the study drug dose at a time that is after the time of the scheduled study visit, the subject should follow the regular dosing 
schedule and the PK sample should be collected at any time during the visit.  For all other visits, PK samples should be collected at any time during the visit and the subject 
should follow the regular dosing schedule.
s.
A stool sample will be collected at each time point indicated for FCP.  For the visit that endoscopy will be conducted, stool sample should be collected prior to bowel prep.  
Subjects will be asked to provide a stool sample at the visit, if possible, or the site will give instructions and a stool sample supply kit.
t.
Diary information collected during Screening will serve to calculate Baseline CDAI.
u.
Collection of SAEs begins the day the subject signs the informed consent form.
v.
Only for subjects continuing into Part 2.

w.
Diary review includes a review of ePRO data (number of total and liquid or very soft stools, stool consistency per Bristol Stool Chart (Appendix F), use of medications used 
for endoscopy preparation, if an endoscopy was performed, AP, and general well-being).
x.
During Screening, biologic drug levels may be optionally assessed at the investigator's discretion as an alternative to completing the required washout period: (1) infliximab 
and natalizumab:  may be tested approximately 4 weeks from the last dose; (2) adalimumab, certolizumab, golimumab, or vedolizumab: may be tested approximately 6 weeks 
from the last dose; (3) ustekinumab:  may be tested approximately 8 weeks from the last dose.
y.
Only if subject provides written consent to collect the samples; if the informed consent form is not signed, no samples can be collected. 
z.
Optional stool samples for proteomic and microbiota analyses may be evaluated in approximately 100 subjects (fecal biomarker substudy).
aa.
If subject provides written consent, intestinal biopsy samples for histology and exploratory analyses will be collected in approximately 200 subjects as a substudy; if the 
informed consent form is not signed, no intestinal biopsy can be collected.  Biopsies will be obtained at Screening and at the Week 12 endoscopy; and at Week 24/PD, if the 
subject participates in Part 2.
ab.
During the COVID-19 pandemic, when a lab test cannot be collected per protocol, the administration and dispensing of study drug should occur if the investigator feels it is 
safe to continue study drug based on the remote visit, at least one post-Baseline lab test is available and no longer than 6 weeks have passed since the last safety lab tests.  A 
local laboratory can be utilized when it is not feasible to use the central laboratory.

for endoscopy preparation, if an endoscopy was performed, AP, and general well-being).
x.
During Screening, biologic drug levels may be optionally assessed at the investigator's discretion as an alternative to completing the required washout period: (1) infliximab 
and natalizumab:  may be tested approximately 4 weeks from the last dose; (2) adalimumab, certolizumab, golimumab, or vedolizumab: may be tested approximately 6 weeks 
from the last dose; (3) ustekinumab:  may be tested approximately 8 weeks from the last dose.
y.
Only if subject provides written consent to collect the samples; if the informed consent form is not signed, no samples can be collected. 
z.
Optional stool samples for proteomic and microbiota analyses may be evaluated in approximately 100 subjects (fecal biomarker substudy).
aa.
If subject provides written consent, intestinal biopsy samples for histology and exploratory analyses will be collected in approximately 200 subjects as a substudy; if the 
informed consent form is not signed, no intestinal biopsy can be collected.  Biopsies will be obtained at Screening and at the Week 12 endoscopy; and at Week 24/PD, if the 
subject participates in Part 2.
ab.
During the COVID-19 or any pandemic, when a lab test cannot be collected per protocol, the administration and dispensing of study drug should occur if the investigator feels 
it is safe to continue study drug based on the remote visit, at least one post-Baseline lab test is available and no longer than 6 weeks have passed since the last safety lab tests.  
A local laboratory can be utilized when it is not feasible to use the central laboratory.
