2 INTRODUCTION
2.1 Background and Rationale
Why Is This Study Being Conducted?
Exocrine pancreatic insufficiency (EPI) is a debilitating condition that is caused by the inadequate 
secretion, delivery or activity of pancreatic enzymes and bicarbonate needed for normal digestion and is 
commonly associated with a wide range of chronic diseases, including cystic fibrosis (CF), chronic 
pancreatitis (CP), and pancreatic cancer. There are approximately 190,000 patients in the United States 
(US) managing their EPI with pancreatic enzyme replacement therapy (PERT).1
Pancreatic enzyme replacement therapy is the cornerstone of EPI treatment.  Without PERT, patients 
may suffer from maldigestion and malabsorption and associated consequences, such as weight loss, 
malnutrition and sarcopenia.2-4  Pancrelipase delayed-release (DR) capsules is a PERT currently approved 
and marketed in the US by AbbVie as Creon® for the treatment of EPI due to CF, CP, pancreatectomy or 
other conditions.5 Currently approved and marketed Creon is manufactured using active pharmaceutical 
ingredient (API) produced at 
.
In order to protect Creon's supply chain through site and geographic diversity, AbbVie invested in new 
equipment and manufacturing site expansion to replicate the manufacturing process for pancrelipase 
DR API at an alternate site 
, in order 
to produce Creon using SPL API (CREON-SPL).  This study is being conducted to evaluate the clinical 
symptoms of EPI in subjects treated with the Creon manufactured with SPL API (CREON-SPL).
Information on CREON-ABT and CREON-SPL can be found in Section 5.9.  Further information on 
pancrelipase DR currently marketed as Creon® in the US can be found in the US Product Information 
(USPI).5
2.2 Benefits and Risks to Subjects
All subjects enrolled in this study will receive treatment for EPI during the study.  This is the primary 
benefit to subjects for this study.
The safety and efficacy of Creon has been well described in subjects with EPI.  The safety data describe a 
well-tolerated regimen, and the use of Creon is supported by a favorable benefit-risk profile.  Risks of 
study participation include those currently listed in the USPI for Creon,5 and are not expected to be 
different for CREON-SPL.
For further details, please see the current Creon Investigator's Brochure and the current product insert.5

3 OBJECTIVES AND ENDPOINTS
3.1 Objectives, Hypotheses, and Estimands
This is a descriptive, exploratory study.
The objective of this study is to evaluate the clinical symptoms of EPI in subjects treated with 
CREON-SPL.  No clinical hypothesis is being tested.
3.2 Pharmacodynamic Endpoints

Total Symptom Score (TSS) as defined in the Pancreatic Exocrine Insufficiency Questionnaire 
(PEI-Q) at Days 1, 8, 15, 29 and 85.

Abdominal Symptom Domain Score (ASDS) as defined in PEI-Q at Days 1, 8, 15, 29 and 85.

Bowel Movement Symptom Score (BMSS) as defined in PEI-Q at Days 1, 8, 15, 29 and 85.
3.3 Safety Endpoints
Safety evaluations include monitoring of treatment-emergent adverse events (TEAEs).
A TEAE compatible with the clinical symptoms of EPI will be considered an adverse event of special 
interest (AESI) for this study and will be summarized separately.
4 INVESTIGATIONAL PLAN
4.1 Overall Study Design and Plan
This is a Phase 4, prospective, single-arm, single-blinded study (subject will not be aware of the order in 
which study drugs are dispensed).  Approximately 30 subjects will be enrolled.
Female subjects of childbearing potential who have a positive pregnancy test during Screening, are not 
eligible to rescreen. Subjects who fail screening due to other reasons can be rescreened once.  In the 
event of rescreening, only prior disqualifying criterion/criteria will need to be repeated.
This study will consist of 4 periods as follows:
Screening Period:  Subjects have up to 14 days following the Screening Visit to confirm eligibility and 
enroll into the study at the Run-In Visit (RIV).  If all eligibility criteria can be verified during the Screening 
Visit, the RIV can occur on the same day as the Screening Visit, and the subject can be enrolled in the 
study and be dispensed Creon-ABT. If full eligibility cannot be confirmed at the Screening Visit, the 
subject will schedule the RIV on a separate date.

STUDY M21-432  |  Version 1.0 
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
Run-in Period:
At the RIV, after eligibility is confirmed, the subject will be dispensed blinded Creon 24,000 lipase units 
(LU) manufactured with Abbott API (CREON-ABT) to be used for the duration of the Run-in Period (28 
days) at the same stable individual dose of Creon he/she was on before Screening.  This assures that the 
Day 1 assessment reflects the symptoms on stable CREON-ABT use.
Treatment Period:  Subjects who complete the Run-in Period will be assessed for the continuation 
criteria at Day 1.  Only subjects who meet all continuation criteria will be dispensed additional study 
drug.  Blinded CREON-ABT study drug from the Run-In Period will be returned, and the subject will be 
dispensed blinded Creon 24,000 LU manufactured with SPL API (CREON-SPL) to use at the same stable 
individual dose per LU of Creon he/she was on before Screening and during the Run-in Period.  This 
assures that the treatment assessments after Day 1 reflect the symptoms on CREON-SPL.  Symptoms 
will be assessed at Day 1 and over both short- (Day 8) and long-term (Days 15, 29, and 85).  Study 
procedures, including assessment of EPI symptoms and adverse events (AEs), will be conducted at each 
visit.
Post-Treatment Period:  Subjects who complete or prematurely discontinue the Treatment Period will 
be followed for 30 days, through a safety follow-up telephone contact, to assess symptoms and to verify 
the subject's well-being.
The schematic of the study is shown in Figure 1.  Further details regarding study procedures are located 
in the Operations Manual.
See Section 5.1 for information regarding eligibility criteria.
See Section 5.2 for information regarding the continuation criteria.

CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
Study completion for each subject is defined as the date of the follow-up telephone contact or the 
premature study discontinuation visit, whichever comes later.  The maximum duration of study 
participation is approximately 157 days for each subject.
4.2 Discussion of Study Design
A single-arm, single-blind, prospective, longitudinal design is considered appropriate to evaluate 
symptoms, as the assessments being performed are reported by the subject (patient reported outcome 
[PRO]).  The 7-day recall period of the PEI-Q instrument assures that the measurement obtained at Day 
1 reflects the symptoms under CREON-ABT, i.e., before the switch to CREON-SPL.  Providing CREON-ABT
for 28 days before Day 1, assures the stability of the effect of CREON-ABT at the time it is assessed at 
Day 1.  Because of the subjective nature of symptom assessment, the subjects will be blinded to which 
study drug they are receiving at each point in the study.  The investigators will know the sequence of 
assignment of study drug but must not inform the subject of this assignment.
Additionally, a study with a simple design (e.g., utilizing telemedicine visits, avoiding confinement 
period, diet standardization or stool collection) was chosen to facilitate study execution during the 
current SARS-CoV-2 epidemic, in alignment with the study objective.  The number of in-person visits was 
minimized to essential visits where labs are collected, or study drug is dispensed/reconciled.  Most study 
visits will be conducted remotely via a telemedicine visit or a phone call.
Appropriateness of Measurements
Standard statistical, clinical, and laboratory procedures will be utilized in this study.  All 
pharmacodynamic and safety-related measurements in this study are standard for assessing disease 
activity in subjects with CF or CP.  All clinical and laboratory procedures in this study are standard and 
generally accepted.
The pharmacodynamic assessments will be conducted using an EPI-specific PRO measure – the PEI-Q.  
The PEI-Q is an 18-item PRO measure designed to assess EPI symptoms and associated impact.6,7  The 
PEI-Q has demonstrated good content validity, reliability, and psychometric properties via the conduct 
of qualitative concept elicitation, cognitive debriefing interviews and quantitative psychometric 
evaluation studies in EPI patients due to CF and CP.6,7
Suitability of Subject Population
Male and female subjects with EPI and CF or CP who meet all of the eligibility criteria at the RIV will be 
eligible to enroll into the study.  Subjects who meet the continuation criteria at Day 1 will be allowed to 
initiate the Treatment Period of the study.  The instrument that will be used to assess EPI symptoms 
(PEI-Q) was developed in a population of CF and CP patients.  As subjects are required to be clinically 
controlled in their current PERT regimen, and subjects with a TSS ≥ 1.8 are most likely poorly clinically 
controlled, those subjects will be excluded.
Selection of Doses in the Study
This study does not select a specific dose of pancrelipase. The individualized dose that the subject is 
using before and during Screening will be maintained throughout the Run-in and Treatment Periods, as

advised on the continued scientific importance of their data even if they discontinue treatment with 
study drug early.
If a subject prematurely discontinues study participation (withdrawal of informed consent), the 
procedures outlined for the Premature Discontinuation Visit (PD Visit) should be completed as soon as 
possible, preferably within 2 weeks.  In addition, if subject is willing, a 30-day follow-up phone call after 
the last dose of study drug may be completed to ensure all treatment-emergent AEs/serious adverse 
events (SAEs) have been resolved.
5.9 Study Drug 
Study drug will only be shipped to clinical sites that have provided the sponsor (or an authorized 
representative) with all required study documents, including Independent ethics 
committee/institutional review board (IEC/IRB) approval, and have signed a clinical study agreement.
Study drug capsules (CREON-ABT or CREON-SPL) will be taken orally with each meal and snack (as per 
patient's usual practice) with enough fluids to swallow the capsules completely.  Capsules must be 
swallowed whole (capsules must not be crushed, chewed, or opened).  Subjects will maintain 
throughout the study the same stable individual dose per LU of Creon they were on before initiating 
Screening.
If the Screening Visit and the RIV do not occur on the same day, subjects will continue their existing 
stable dose of commercial Creon until the RIV.
At the RIV, eligible subjects will be dispensed blinded Creon 24,000 LU manufactured with Abbott API 
(CREON-ABT) for the Run-in Period. At the RIV, and for the duration of the study, eligible subjects will 
stop using the commercial Creon 24,000 LU capsules they were taking before the RIV and begin taking 
the same corresponding number of capsules at meals and snacks (maintaining the same daily dosing as 
prescribed by their doctor), using the 24,000 LU capsules dispensed as study drug.  If the subject is using 
more than one strength of commercial Creon capsules, the subject will keep taking the commercial 
Creon capsules of any other strength besides the 24,000 LU strength at the same previous dose and will 
switch the 24,000 LU capsules from the commercial Creon they were using before Screening to the 
24,000 LU capsules dispensed as study drug.
At Day 1, subjects will return all the bottles dispensed at the RIV.  Subjects who meet all continuation 
criteria at Day 1 will be dispensed blinded Creon 24,000 LU manufactured with SPL API (CREON-SPL) for 
the Treatment Period at the same dose used during the Run-in Period.

STUDY M21-432  |  Version 1.0 
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
The subjects will be blinded to the type of study drug they will be receiving; therefore, site personnel 
MUST NOT inform the subject whether they are receiving CREON-ABT or CREON-SPL at each 
dispensation visit, in order to maintain the single-blind of the study.
If a subject forgets to take their study drug dose at their regularly scheduled dosing time, they should 
take the next dose at the next snack or meal. Information on the study drugs is provided in Table 1.  
AbbVie-provided study drug must not be substituted.  Direct-from-patient shipping at Day 85/PD Visit is 
also described in the Operations Manual (Appendix E).
The subject will be instructed to return all drug containers (even if empty) to the study site personnel at 
the completion of the Run-in and Treatment Periods.  The study site personnel will document study drug 
usage.
Pancrelipase (CREON-ABT or CREON-SPL) will be packaged in bottles with quantities sufficient to 
accommodate the study design. Each kit will be labeled per local requirements and this label must 
remain affixed to the kit.  Upon receipt, study drug should be stored as specified on the label and kept in 
a secure location.  Each kit will contain a unique kit number.  This kit number is assigned to a subject via 
interactive response technology (IRT) and encodes the appropriate study drug to be dispensed at the 
subject's corresponding study visit.  Site staff will complete all blank spaces on the label before 
dispensing to subjects.  Study drug will only be used for the conduct of this study.

CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
Digital Health Tools Accountability
The investigator or his/her representative will verify that the digital health tools (e.g., PRO devices) are 
received intact and in the correct amounts.  A proof of receipt or similar document will be kept in the 
site files as a record of what was received.
In addition, sites will maintain records of traceability, accountability, and return including but not limited 
to date received/dispensed/returned, subject number, and the identification of the person 
dispensing/returning the digital health tools.
5.10 Drug Assignment
This is a single-arm study, and all eligible subjects will receive both study drugs (CREON-ABT during the 
Run-in Period; CREON-SPL during the study Treatment Period).  However, to blind subjects to the 
sequence of study drugs, the IRT system will be used to allocate drug.
All subjects will be assigned a unique subject identification number by the IRT at the Screening Visit.  For 
subjects who rescreen, the subject number assigned by the IRT at the initial Screening Visit should be 
used.
AbbVie personnel, the investigator, study site personnel, and anyone with access to the full protocol, 
will be unblinded to the sequence of study drug assignment. Only subjects will remain blinded to their 
treatments throughout the study.  To maintain the subject blind, the CREON-SPL and CREON-ABT
capsules provided for the study will be identical in appearance. The investigator, study site personnel 
must not inform the subject of the order they will receive the 2 study drugs. The subject should remain 
blinded even if the subject experiences an AE.
5.11 Protocol Deviations
AbbVie does not allow intentional/prospective deviations from the protocol except when necessary to 
eliminate an immediate hazard to study subjects.  The investigator is responsible for complying with all 
protocol requirements, written instructions, and applicable laws regarding protocol deviations.  If a 
protocol deviation occurs (or is identified, including those that may be due to the COVID-19 pandemic), 
the investigator is responsible for notifying independent ethics committee (IEC)/independent review 
board (IRB), regulatory authorities (as applicable), and AbbVie.
5.12 Data Monitoring Committee
The external, independent data monitoring committee (DMC) will review unblinded safety data during 
the study.  The DMC Charter for Study M21-432 will include, but is not limited to, the following:  the 
frequency and scope of data reviews, the suggested relevant data to be included in the review, the DMC 
responsibilities, and the DMC members and their credentials.
Since this is a single-arm, single-blinded study and the sponsor is unblinded, the sponsor will be 
responsible for performing the DMC analyses described in the DMC Charter as well as any additional 
analyses requested by the DMC.

6 SAFETY CONSIDERATIONS
6.1 Complaints and Adverse Events
Complaints
A complaint is any written, electronic, or oral communication that alleges deficiencies related to the 
physical characteristics, identity, quality, purity, potency, durability, reliability, safety, effectiveness, or 
performance of a product/device.  Complaints associated with any component of this investigational 
product must be reported to AbbVie.
Product Complaint
A product complaint is any complaint related to the biologic or drug component of the product or to the 
medical device component(s).
For a product this may include, but is not limited to, damaged/broken product or packaging, product 
appearance whose color/markings do not match the labeling, labeling discrepancies/inadequacies in the 
labeling/instructions (e.g., printing illegible), missing components/product, device damage or not 
working properly, or packaging issues.
Product complaints concerning the investigational product and/or device must be reported to AbbVie 
within 24 hours of the study site's knowledge of the event.  Product complaints occurring during the 
study will be followed up to a satisfactory conclusion.
Medical Complaints/Adverse Events and Serious Adverse Events
An AE is defined as any untoward medical occurrence in a subject or clinical investigation subject 
administered a pharmaceutical product and which does not necessarily have a causal relationship with 
this treatment.  An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
(investigational) product, whether or not the event is considered causally related to the use of the 
product.
Such an event can result from use of the drug as stipulated in the protocol or labeling, as well as from 
"special situations" such as accidental or intentional overdose, medication error, occupational or 
accidental exposure, off-label use, drug abuse, drug misuse, or drug withdrawal, all which must be 
reported whether associated with an AE or not. Any worsening of a pre-existing condition or illness is 
considered an AE.  Worsening in severity of a reported AE should be reported as a new AE.  Laboratory 
abnormalities and changes in vital signs are considered to be AEs only if they result in discontinuation 
from the study, necessitate therapeutic medical intervention, and/or if the investigator considers them 
to be AEs.
The investigators will monitor each subject for clinical and laboratory evidence of AEs on a routine basis 
throughout the study.  All AEs will be followed to a satisfactory conclusion.
An elective surgery/procedure scheduled to occur during a study will not be considered an AE if the 
surgery/procedure is being performed for a pre-existing condition and/or the surgery/procedure has 
Page 21 of 54
 

STUDY M21-432  |  Version 1.0 
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
All AEs reported from the time of first study drug administration until 30 days after discontinuation of 
study drug administration will be collected, whether solicited or spontaneously reported by the subject.  
In addition, study procedure-related serious and nonserious AEs will be collected from the time the 
subject signs the study-specific informed consent.
Adverse events will be monitored throughout the study to identify any of special interest for this study.
Adverse Events of Special Interest
The following TEAEs compatible with clinical symptoms of EPI will be considered AESI for this study:

Diarrhea 

Abdominal pain

Abdominal bloating

Flatulence

Steatorrhea
Patients with signs and symptoms suggestive of worsening EPI should be evaluated and treated as 
clinically indicated by the investigator.
Adverse Event Severity and Relationship to Study Drug
The investigators will rate the severity of each AE as mild, moderate, or severe.
The investigator will use the following definitions to rate the severity of each AE:
Mild
The adverse event is transient and easily tolerated by the subject.
Moderate
The adverse event causes the subject discomfort and interrupts the subject's 
usual activities.
Severe
The adverse event causes considerable interference with the subject's usual 
activities and may be incapacitating or life threatening.
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 to Creon 
24,000 LU dispensed as CREON-ABT or CREON-SPL.
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 to Creon 
24,000 LU dispensed as CREON-ABT or CREON-SPL.

STUDY M21-432  |  Version 1.0 
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
Pregnancy
While not an AE, pregnancy in a study subject must be reported to AbbVie within 24 hours after the site 
becomes aware of the pregnancy.  Subjects who become pregnant during the study must be 
discontinued (Section 5.7).  If a pregnancy occurs in a study subject, information regarding the 
pregnancy and the outcome will be collected.
The pregnancy outcome of an elective or spontaneous abortion, stillbirth or congenital anomaly is 
considered a SAE and must be reported to AbbVie within 24 hours after the site becomes aware of the 
event.
6.2 Management of COVID-19 Infection
Clinical management of confirmed or suspected COVID-19 infection during the study will be handled by 
the investigator according to treatment guidelines and local standard of care.
For suspected COVID-19 infection, prompt and comprehensive evaluation should be performed to 
confirm COVID-19 infection or exclude other causes (e.g., influenza).  For negative COVID-19 results, the 
investigator should consider re-testing based on clinical suspicion (exposures, clinical findings).
All cases of suspected or confirmed COVID-19 infection must be discussed with the Sponsor/Emergency 
Medical Contact regarding additional COVID-19 testing, alternative etiologies and/or study visit 
disposition (including but not limited to the possibility of screen fail due to an expiring screening 
window, premature discontinuations, etc.).
7 STATISTICAL METHODS & DETERMINATION OF SAMPLE SIZE
7.1 Statistical and Analytical Plans
The statistical methods provided in this protocol will be focused on high level description of the 
statistical analyses.  Complete and specific details of the statistical analysis will be described in the 
Statistical Analysis Plan (SAP).
The planned analyses will be conducted after all subjects have completed the study or prematurely 
discontinued from the study.
7.2 Definition for Analysis Populations
The Full Analysis Set (FAS) includes all enrolled subjects who received at least 1 dose of study drug of 
CREON-SPL.  The FAS will be used for the summary of subject disposition and baseline characteristics.
A Per-Protocol (PP) Population includes all enrolled subjects who received at least 1 dose of study drug 
of CREON-SPL, had Day 1 (baseline) PEI-Q scores collected, and had at least one post-baseline PEI-Q 
scores collected during the Treatment Period (Days 8, 15, 29, and 85).  The pharmacodynamic endpoints 
will be analyzed in the PP Population.
Page 24 of 54
 

STUDY M21-432  |  Version 1.0 
CONFIDENTIAL INFORMATION
No use or disclosure outside AbbVie is permitted without prior written authorization from AbbVie.
The Safety Analysis Set for CREON-ABT (SAS-CREON-ABT) consists of all subjects who received at least 1 
dose of CREON-ABT study drug during the Run-in Period. The Safety Analysis Set for CREON-SPL (SAS-
CREON-SPL) consists of all subjects who received at least 1 dose of CREON-SPL study drug.
7.3 Handling Potential Intercurrent Events for the Study Endpoints
The pharmacodynamic endpoints (TSS, ASDS and BMSS) will be analyzed based on the PP population 
and the following potential intercurrent events will be addressed:

Subjects who did not receive any dose of study drug CREON-SPL will be excluded from the PP 
population.

Subjects who did not have baseline (Day 1) PEI-Q score data or did not have any post-baseline 
PEI-Q score data will be excluded from the PP population. 
Subjects who have missing PEI-Q data for the visit will be excluded from the analysis of that visit.
7.4 Statistical Analyses for Pharmacodynamic Endpoints
Summary and Analysis of the Pharmacodynamic Endpoints
Analyses of the pharmacodynamic endpoints will be conducted on the PP population.  Descriptive 
statistics (N, mean, standard deviation [SD], median, minimum, and maximum) will be used to 
summarize the TSS as well as the symptom score for each domain of abdominal symptoms and bowel 
movement symptoms from PEI-Q.  The summaries will be provided for the Screening Visit, Baseline Visit 
(Day 1), each Post-Baseline Visit (Days 8, 15, 29, 85), and the change from baseline for each.  Two-sided 
95% confidence interval based on t-distribution will also be provided for the mean estimate of each 
score at each visit, and the mean change from baseline for each post-baseline visit.
7.5 Statistical Analyses for Safety
Safety analyses will be provided based on safety analysis sets.  Number and proportion of subjects 
reporting a TEAE during the Run-in Period (CREON-ABT) and Treatment Period (CREON-SPL), will be 
summarized separately using SAS-CREON-ABT and SAS-CREON-SPL, respectively.  A TEAE compatible 
with the clinical symptoms of EPI (see Section 6.1) will be considered an AESI and will be summarized 
separately.  Details of the safety analyses will be provided in the SAP.
Adverse event will be coded using MedDRA. A -TEAE is defined as an AE with an onset date on or after 
the first dose of corresponding study drug and within 30 days after the last dose of study drug or 
initiation of the next study drug, whichever is earlier.  The number and percentage of subjects 
experiencing TEAEs will be tabulated using MedDRA system organ class (SOC) and preferred term (PT), 
as well as by severity and by relationship to the study drug as assessed by the investigator.  Summaries 
(i.e., number and percentages) of TEAEs, SAEs, deaths, AEs leading to discontinuation, and AESIs will be 
provided.

7.6 Overall Type I Error Control
Not applicable for this study as the study will provide descriptive statistics with no hypothesis testing.
7.7 Sample Size Determination
Approximately 30 subjects will be enrolled at the RIV.  The sample size is calculated based on the 
descriptive statistics for the TSS based on PEI-Q.  No formal statistical hypothesis testing is planned.  
Assuming a dropout rate of 20% after the RIV, the number of evaluable subjects will be around 24 for 
the analysis of pharmacodynamic endpoints.
Based on Johnson CD, et al,6 the average TSS from PEI-Q was estimated to be 1.4 (SD = 0.7) for CP and CF 
subjects with EPI symptoms.  Assuming the covariance between the TSS at baseline and post-baseline 
after switching to CREON-SPL to be 0.365, the SD for the change of the TSS between baseline and post-
baseline is estimated to be 0.5.  A sample size of 24 evaluable subjects will provide a precision of ± 0.2 in 
terms of half-length of the 95% confidence interval for the estimate of change in TSS based on PEI-Q.
8 ETHICS
8.1 Independent Ethics Committee/Institutional Review Board 
(IEC/IRB)
The protocol, ICF, recruitment materials, and all subject materials will be submitted to the IEC/IRB for 
review and approval.  Approval of both the protocol and the ICF must be obtained before any subject is 
enrolled.  Any amendment to the protocol will require review and approval by the IEC/IRB before the 
changes are implemented to the study.  In addition, all changes to the consent form(s) will be IEC/IRB 
approved.
8.2 Ethical Conduct of the Study
The study will be conducted in accordance with the protocol, Operations Manual, International Council 
for Harmonisation (ICH) guidelines, applicable regulations, and guidelines governing clinical study 
conduct and the ethical principles that have their origin in the Declaration of Helsinki.  Responsibilities of 
the investigator are specified in Appendix B.
In the event a significant disaster/crisis (e.g., epidemic/pandemic, natural disaster, conflict/combat) 
occurs leading to difficulties in performing protocol-specified procedures, AbbVie may 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 lab instead of a central lab), and shipping investigational 
product and/or supplies direct to subjects 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.
8.3 Subject Confidentiality
To protect subjects' confidentiality, all subjects and their associated samples will be assigned numerical 
study identifiers or "codes."  No identifiable information will be provided to AbbVie.
9 SOURCE DOCUMENTS AND CASE REPORT FORM 
COMPLETION
The investigator is responsible for ensuring the accuracy, completeness, legibility, and timeliness of the 
data reported.  All source documents should be attributable, legible, contemporaneous, original, 
accurate, and complete to ensure accurate interpretation of data.  Clinical site monitoring is conducted 
to ensure that the rights and well-being of human subjects are protected, that the reported trial data 
are accurate, complete, and verifiable, and that the conduct of the trial is in compliance with the 
currently approved protocol, ICH Good Clinical Practice (GCP), and applicable local regulatory 
requirement(s). During the COVID-19 pandemic, remote monitoring of data may be employed if allowed 
by the local regulatory authority, IRB/IEC, and the study site.
10
DATA QUALITY ASSURANCE
AbbVie will ensure that the clinical trial is conducted with a quality management system that will define 
quality tolerance limits in order to ensure human subject protection and reliability of study results.  Data 
will be generated, documented, and reported in compliance with the protocol, ICH GCP, and applicable 
regulatory requirements.
