PROTOCOL SUMMARY
Study Title
A Phase 3, randomized, double-blind, placebo-controlled, multicenter study to investigate the 
efficacy and safety of mongersen (GED-0301) for the treatment of subjects with active Crohn’s 
disease.
Indication
Mongersen (GED-0301) is being studied for the treatment of subjects with active Crohn’s 
disease (CD) and ulcerative colitis (UC). Although the etiology of CD has not been completely 
elucidated, there has been significant advancement in the understanding of the disease 
pathogenesis.  There is evidence that the chronic intestinal inflammation is caused by an 
excessive immune response to mucosal antigens that is not appropriately controlled by the 
normal counter-regulatory mechanisms.  One of the counter-regulatory mechanisms involves 
transforming growth factor-beta 1 (TGF-β1).  TGF-β1 is a multifunctional factor that has been 
shown to be involved in regulating growth, differentiation, and function of immune and 
nonimmune cells (Monteleone, 2001). TGF-β1 has been shown to play an important role in the 
control of immune homeostasis and acts as a potent negative regulator of mucosal inflammation.  
TGF-β1 knockout mice developed a severe multiple-organ inflammatory disease, in which the 
lymphocytic infiltration of the affected organs was associated with increased production of tumor 
necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ).  Studies have shown that 
abrogation of TGF-β1 signaling in T cells alone is sufficient to disrupt T and B cell homeostasis 
and induce T cell-mediated inflammatory lesions in various organs, including the intestine.  It 
has been widely demonstrated that neutralization of TGF-β1 results in the induction and/or 
amplification of pathogenic responses responsible for the development of experimental colitis 
resembling either CD or UC (Monteleone, 2012). 
TGF-β1 signaling is regulated by Smads, a family of proteins that serve as substrates for TGF-β1 
type I and type II receptors.  The TGF-β type I receptor recognizes Smad2 and Smad3 which, 
upon phosphorylation of Smad3, en route to the nucleus, associate with Smad4, forming 
complexes that participate in transcriptional control of target genes.  In addition to the activating 
Smads, inhibiting Smad also exists.  Smad7 interacts with activated receptors and prevents 
phosphorylation of Smad2 and Smad3.  The advance in the understanding of the involvement of 
the TGF-β signaling pathway in the pathogenesis of CD and the identification of the role of 
Smad7 in IBD has provided the rationale for the development of a new drug that, through the 
inhibition of Smad7 expression, could restore TGF-β1 signaling, thus inhibiting the production 
of pro-inflammatory molecules such as TNF-α and IFN-γ.
GED-0301 is an investigational medicinal product in clinical development for the treatment of 
CD and UC.  GED-0301 is an antisense oligodeoxynucleotide that is complementary to the 
sequence of the messenger ribonucleic acid (mRNA) transcript of Smad7. Orally administered 
GED-0301 is formulated as a gastro-resistant delayed release pH-dependent tablet designed to 
deliver the active substance in the distal gastrointestinal (GI) tract with negligible systemic 
exposure. 
Please refer to the Investigator’s Brochure for detailed information concerning the available 
pharmacology, toxicology, drug metabolism, clinical studies, and adverse event (AE) profile of 
the investigational product (IP).

Study Design
This is a Phase 3, randomized, double-blind, placebo-controlled, multicenter study to evaluate 
the efficacy and safety of 3 treatment regimens of oral GED-0301 versus placebo in subjects 
with active CD (defined by a CDAI score ≥ 220 and ≤ 450 and a total SES-CD ≥ 6 at screening, 
or the ileum segmental SES-CD ≥ 4 at screening). Approximately 1064 subjects will be 
randomized in a 1:1:1:1 ratio (266 subjects per GED-0301 arm [total 798] and 266 subjects in the 
placebo arm) to receive 1 of 3 double-blind, oral GED-0301 treatment regimens, or identically 
appearing placebo, once daily (QD) for 52 weeks. The total number of subjects with a total SES-
CD score ≥ 6 is targeted to comprise approximately 80% of the study population.
Treatment assignment at baseline (Week 0/Visit 2) will be stratified via an Interactive Web 
Response System (IWRS) based on concomitant use of corticosteroids (yes/no); concomitant use 
of immunosuppressants (eg, azathioprine [AZA], 6-mercaptopurine [6-MP], or methotrexate 
[MTX]) (yes/no), and previous exposure to biologics (ie, infliximab, adalimumab, certolizumab
or vedolizumab) (yes/no).  The total number of subjects with previous exposure to biologics is 
targeted to comprise approximately 35% of the study population.
Subjects will receive double-blind, oral GED-0301 or identically appearing placebo (QD) as 
follows (Table 4):
!
GED-0301 160 mg QD for 12 weeks; followed by placebo QD for 4 weeks; followed by 
alternating GED-0301 160 mg QD for 4 weeks and placebo QD for 4 weeks, until the 
the Week 52 Visit;
!
GED-0301 160 mg QD for 12 weeks; followed by placebo QD for 4 weeks; followed by 
alternating GED-0301 40 mg QD for 4 weeks and placebo QD for 4 weeks, until the 
Week 52 Visit;
!
GED-0301 160 mg QD for 12 weeks; followed by continuous GED-0301 40 mg QD, 
until the Week 52 Visit;
!
Placebo QD until the Week 52 Visit.
Subjects who complete the GED-0301-CD-002 study at the Week 52 Visit may enter the Long-
term Active-treatment Study (GED-0301-CD-004). Subjects who meet the criteria for early 
escape beginning at the Week 12 Visit and thereafter until the Week 52 Visit, may (a) continue 
in the study at the discretion of the Investigator based on the totality of clinical data, (b) enter the 
Long-term Active-treatment Study (GED-0301-CD-004), or (c) discontinue the study.
The criteria for early escape are defined as 
 
(Table 7).
Subjects may discontinue the study at any time. Subjects who discontinue from the study at 
Week 12 (either because they meet the early escape criteria or for any other reason), will 
complete the Week 12 Visit. Subjects who prematurely discontinue from the study at any other

time prior to the Week 52 Visit, including subjects who early escape into the Long-term Active-
treatment Study, will complete the Early Termination (ET) Visit (Section 6.3). The ET Visit
should be scheduled as soon as possible after the last dose of IP. 
Subjects who complete the Week 52 Visit, as well as subjects who prematurely discontinue from 
the study, will have a 4-week Follow-up Visit. If the ET Visit occurs 28 days or more after the
last dose of IP, then the Follow-up Visit is not required. 
Subjects entering the Long-term Extension Study will not have the Follow-up Visit. 
The study will be conducted in compliance with International Council for Harmonisation (ICH) 
Good Clinical Practices (GCPs) and applicable regulatory requirements.

Length of Study
Subjects will participate for a maximum of 60 weeks in this study: up to 4 weeks in the 
Screening Period; 52 weeks in the Double-blind Treatment Period; and 4 weeks in the Follow-up 
Period.
The End of Study is defined as either the date of the last visit of the last subject to complete the 
post-treatment follow-up, or the date of receipt of the last data point from the last subject that is 
required for primary, secondary and/or exploratory analysis, as prespecified in the protocol, 
whichever is the later date.
Study Treatments
Subjects will receive double-blind, oral GED-0301 or identically appearing placebo QD as 
follows:
!
GED-0301 160 mg QD for 12 weeks; followed by placebo QD for 4 weeks; followed by 
alternating GED-0301 160 mg QD for 4 weeks and placebo QD for 4 weeks, until the 
Week 52 Visit;
!
GED-0301 160 mg QD for 12 weeks; followed by placebo QD for 4 weeks; followed by 
alternating GED-0301 40 mg QD for 4 weeks and placebo QD for 4 weeks, until the 
Week 52 Visit;
!
GED-0301 160 mg QD for 12 weeks; followed by continuous GED-0301 40 mg QD, 
until the Week 52 Visit;
!
Placebo QD until the Week 52 Visit.

Statistical Methods
The intent-to-treat (ITT) population will be the primary population for the efficacy analysis.  The 
ITT population will consist of all subjects who are randomized and receive at least 1 dose of IP.  
Subjects will be included in the treatment group to which they were randomized for the efficacy 
analysis using the ITT population.
For the efficacy analyses of the first 12 weeks of the study, the 3 GED-0301 treatment groups 
will be pooled, due to the same treatment of GED-0301 160 mg QD received during the first 12

weeks, and the treatment comparisons will be made between GED-0301 160 mg QD and 
placebo.  For the efficacy analyses beyond Week 12, the treatment comparisons will be made 
between each of the 3 GED-0301 treatment groups and placebo.
Binary endpoints will be analyzed by the Cochran-Mantel-Haenszel (CMH) test stratified by the 
randomization stratification factors.  Subjects who have insufficient data for response 
determination for the time point under consideration will be considered nonresponders for that 
time point.
 
 
 
 
 
Formal statistical tests are planned for the primary and secondary efficacy endpoints.  In order to 
control the family-wise Type I error rate at the 0.05 level, formal statistical tests will be carried 
out using a gatekeeping closed testing procedure.
The safety analysis will be based on the safety population, which will consist of all subjects who 
are randomized and receive at least 1 dose of IP.  Subjects will be included in the treatment 
group corresponding to the IP they actually received for the analysis using the safety population.
Treatment-emergent adverse events (TEAEs) will be classified using the Medical Dictionary for 
Regulatory Activities (MedDRA) classification system.  All TEAEs will be summarized by 
system organ class, preferred term, severity, and relationship to IP.  TEAEs leading to death or to 
discontinuation from treatment and serious TEAEs will also be tabulated.  In the by-subject 
analysis, a subject having the same event more than once will be counted only once and by 
greatest severity.
Laboratory, vital signs, weight, and ECG data will be summarized descriptively by time point.  
In addition, shift tables showing the number of subjects with values low, normal, and high 
compared to the normal ranges at baseline versus postbaseline will be provided for laboratory 
tests.
With a total of approximately 1064 subjects and a randomization ratio of 1:1:1:1, this study will 
randomize approximately 266 subjects into each of the 3 GED-0301 treatment groups and the 
placebo group.  The study sample size is driven by the comparison of each of the three GED-
0301 treatment groups with placebo with respect to the proportion of subjects with ER-50 at 
Week 52.  The study has > 90% power (at a 2-sided significance level of 0.05 and not accounting 
for multiplicity adjustment; same for the power statements below) to demonstrate the superiority 
of GED-0301 160 mg QD (approximately 798 subjects) over placebo with respect to clinical 
remission at Week 12, assuming response rates of 36% and 22% for the GED-0301 160 mg QD 
and placebo groups, respectively.  The study has > 90% power to demonstrate the superiority of 
a GED-0301 treatment regimen over placebo with respect to clinical remission at Week 52, 
assuming response rates of 36% and 22% for the GED-0301 and placebo groups, respectively.  
The study has 90% power to demonstrate the superiority of a GED-0301 treatment regimen over 
placebo with respect to ER-50 at Week 52, assuming response rates of 20% and 10% for the 
GED-0301 and placebo groups, respectively.

Crohn’s disease (CD) is a chronic, disabling, relapsing, systemic inflammatory disease that 
mainly affects the ileum and the colon, although it may involve any segment of the 
gastrointestinal (GI) tract.  Crohn’s disease may also present with extraintestinal manifestations 
and associated immune disorders (Baumgart, 2012).  It is one of the most common forms of 
inflammatory bowel disease (IBD).  The precise cause of CD is unknown, but it is considered to 
be an autoimmune disease due to a combination of genetic, environmental and immunologic 
factors (MacDonald, 2005).  The peak age of disease onset is between 15 and 25 years of age.  
In North America, the incidence of the disease is estimated to be between 3.1 and 14.6 cases per 
100,000 person-years, with 10,000 to 47,000 new cases of CD diagnosed annually 
(Loftus, 2004).  The overall incidence of CD in Europe is about 5.6 per 100,000 inhabitants (7.0 
per 100,000 person-years in northern centers versus 3.9 in southern centers) (Loftus, 2004).
Patients with CD may present with symptoms that include abdominal pain, diarrhea, and weight 
loss, and the course of the disease can be associated with systemic symptoms such as malaise, 
anorexia, or fever.  Crohn’s Disease has a chronic relapsing course, with approximately half of 
the patients having been in remission at any given time (Loftus, 2002).  Common complications 
are intestinal strictures and fistulas, with an increased frequency over time, occurring in more 
than half of the patients at 20 years after diagnosis, and often requiring surgery (Baumgart, 
2012).  Extraintestinal manifestations have been reported in 6% to 47% of the patients with CD, 
including manifestations which are associated with intestinal activity (eg, peripheral arthritis, 
erythema nodosum, aphthous ulcers); or not (eg, pyoderma gangrenosum, uveitis, 
spondylarthropathy, primary sclerosing cholangitis); non CD-specific autoimmune diseases 
which represent a major susceptibility to autoimmunity only (eg, hemolytic anemia, vitiligo, 
diabetes mellitus, psoriasis) as well as CD-related complications due to metabolic or anatomical 
abnormalities (eg, thromboembolic events, osteopathy, nephrolithiasis) (Vavricka, 2011;
Bernstein, 2005). Additionally, patients with CD are at increased risk of developing small bowel 
and colorectal cancer (Baumgart, 2012). 
Treatment of patients with CD represents a difficult challenge.  The natural history of CD is 
characterized by a remitting and relapsing course that progresses to complications and surgery in 
the majority of patients.  A stepwise approach according to disease location and severity at 
presentation has been advocated, with the primary aim of inducing and maintaining clinical 
remission, improving quality of life (QoL), and minimizing short- and long-term toxicity and 
complications (Lichtenstein, 2009; Dignass, 2010).  Treatment of CD currently involves 
pharmacological treatment and surgery, the latter of which is indicated for medically refractory 
disease, strictures, abscesses and neoplastic lesions.  Pharmacological treatment may involve 
aminosalicylates, antibiotics, glucocorticoids, immunomodulators (azathioprine [AZA], 6-
mercaptopurine [6-MP], and methotrexate [MTX]), and biologic compounds, such as tumor 
necrosis factor-alpha (TNF-α) blockers, natalizumab, and vedolizumab.  Patients with mild to 
moderate disease usually receive aminosalicylates, antibiotics, or budesonide; systemic steroids 
and immunosuppressants, which are used when the initial approach fails or in cases of moderate 
to severe disease, and biologics are usually reserved for refractory cases or severe disease 
(Lichtenstein, 2009).

Although these drugs can provide clinical benefit, they have important limitations. 
Aminosalicylates are minimally effective in patients with CD, antibiotics have not consistently 
demonstrated efficacy in controlled trials, and glucocorticoids, although effective in the short 
term, can cause unacceptable adverse events (AEs) and do not provide a benefit as maintenance 
therapy (Lichtenstein, 2009).  Additionally, immunosuppressant use has been restricted to 
maintenance therapy and is also associated with significant potential toxicities, such as 
malignancies and infections.  Biologics, such as TNF-α blockers, have improved the care of 
patients with CD by providing induction and maintenance of remission and decreasing the need 
for hospitalizations and surgeries, but roughly two-thirds of patients do not achieve remission 
after 1 year of treatment.  Additionally, after failing a TNF-α blocker, the response to a second 
TNF-α blocker is significantly lower.  The TNF-α blockers may predispose to serious safety 
concerns, including opportunistic infections and malignancies (Clark, 2007).
There is a clear need for new therapeutic approaches with a good safety profile in patients with 
CD who do not respond, lose response, or are intolerant to currently available treatments.
1.2.
Compound Background 
GED-0301 inhibits the expression of Smad7, a key regulatory modulator of TGF-β1, by targeting 
a sequence in Smad7 messenger ribonucleic acid (mRNA) (Boirivant, 2006).  There is a marked 
overexpression of Smad7 in the inflamed intestine of patients with IBD, such as CD and UC 
(Monteleone, 2001).  This is associated with a reduction in p-Smad3, a crucial step in TGF-β1-
mediated signal transduction.  By blocking TGF-β1 activity, high Smad7 levels contribute to 
sustained production of proinflammatory molecules (such as IFN-γ and TNF-α) in IBD-affected 
tissues.  The identification of the role of Smad7 in IBD provided the rationale for the 
development of mongersen (GED-0301).
GED-0301 is an investigational medicinal product in clinical development for the treatment of 
CD and ulcerative colitis (UC). GED-0301 is an antisense oligodeoxynucleotide (21-mer) that is 
complementary to the sequence of the messenger ribonucleic acid (mRNA) transcript of Smad7. 
It has a phosphorothioate backbone. It may be described chemically as the fully neutralized 
sodium salt of a 3’ 5’ linked 2’-deoxyribophosphorothioate oligonucleotide 21-mer in which 
each of the 20 internucleotide linkages is an O,O-linked phosphorothioate.  Orally administered 
GED-0301 is formulated as a gastro-resistant delayed release pH-dependent tablet designed to 
deliver the active substance in the distal GI tract with negligible systemic exposure. 
Although the etiology of CD has not been completely elucidated, there has been significant 
advancement in the understanding of the disease pathogenesis.  There is evidence that the 
chronic intestinal inflammation is caused by an excessive immune response to mucosal antigens 
that is not appropriately controlled by the normal counter-regulatory mechanisms.  One of the 
counter-regulatory mechanisms involves transforming growth factor-β1 (TGF-β1).  TGF-β1 is a 
multifunctional factor that has been shown to be involved in regulating growth, differentiation, 
and function of immune and nonimmune cells (Monteleone, 2001). TGF-β1 has been shown to 
play an important role in the control of immune homeostasis and acts as a potent negative 
regulator of mucosal inflammation.  TGF-β1 knockout mice developed a severe multiple-organ 
inflammatory disease, in which the lymphocytic infiltration of the affected organs was associated 
with increased production of TNF-α and interferon-gamma (IFN-γ).  Studies have shown that 
abrogation of TGF-β1 signaling in T cells alone is sufficient to disrupt T and B cell homeostasis

and induce T cell-mediated inflammatory lesions in various organs, including the intestine.  It 
has been widely demonstrated that neutralization of TGF-β1 results in the induction and/or 
amplification of pathogenic responses responsible for the development of experimental colitis 
resembling either CD or UC (Monteleone, 2012).  
TGF-β1 signaling is regulated by Smads, a family of proteins that serve as substrates for TGF-β1 
type I and type II receptors.  The TGF-β type I receptor recognizes Smad2 and Smad3 which, 
upon phosphorylation of Smad3, en route to the nucleus, associate with Smad4, forming 
complexes that participate in transcriptional control of target genes.  In addition to the activating 
Smads, inhibiting Smad also exists.  Smad7, on the other hand, interacts with activated receptors 
and prevents phosphorylation of Smad2 and Smad3.  The advance in the understanding of the 
involvement of the TGF-β signaling pathway in the pathogenesis of CD and the identification of 
the role of Smad7 in IBD has provided the rationale for the development of a new drug that, 
through the inhibition of Smad7 expression, could restore TGF-β1 signaling, thus inhibiting the 
production of pro-inflammatory molecules such as TNF-α and IFN-γ.

Nonclinical Experience
Overall, GED-0301 exhibits an acceptable safety profile in preclinical species and the toxicology 
program for GED-0301 adequately supports the conduct of clinical studies.  
Please refer to the Investigator’s Brochure (IB) for information concerning the available 
preclinical, pharmacology, toxicology and drug metabolism studies of GED-0301.
1.2.2.
Clinical Summary
1.2.2.1.
Clinical Pharmacology
The pharmacokinetics (PK) of GED-0301 were characterized in a Phase 1 first-in-human study 
 in subjects with active CD.  The systemic bioavailability of GED-0301 
following oral administration at dose levels up to 160 mg/day for 7 days to human patients is 
negligible.
1.2.2.2.
Clinical Safety
Three clinical studies have been completed to date:  
, a Phase 1, dose-
escalating, safety and PK study of 7 days of oral administration of GED-0301 in subjects with 
active CD,
 a Phase 2 randomized, double-blind, placebo-controlled, 
dose-finding study of GED-0301 in subjects with active CD and 
, a Phase 
2 randomized, double-blind, placebo-controlled, long-term extension study to evaluate the safety 
and tolerability of GED-0301 40 mg for the maintenance of CD in remission.  
 
 
 No deaths were reported during the conduct 
of the studies.  No safety concerns that could modify the study conduct and/or investigational 
product (IP) administration arose from the studies.
Please refer to the IB for information concerning the available clinical studies and adverse event 
(AE) profile of GED-0301.

Rationale
1.3.1.
Study Rationale and Purpose
The purpose of this Phase 3 study is to demonstrate the efficacy and safety of GED-0301 in 
subjects with active CD to support its registration for the indication of the treatment of active 
CD. Active CD is defined as a CDAI score ≥ 220 and ≤ 450 at screening and a total Simple 
Endoscopic Score for Crohn's Disease (SES-CD) ≥ 6 at screening, or the ileum segmental SES-
CD ≥ 4 at screening. Subjects must have failed or experienced intolerance to at least one of the 
following: budesonide; systemic corticosteroids; immunosuppressants (eg, azathioprine [AZA], 
6-mercaptopurine [6-MP], or methotrexate [MTX]); or biologics (ie, infliximab, adalimumab, 
certolizumab or vedolizumab).
1.3.2.
Rationale for the Study Design
GED-0301-CD-002 is a double-blind, placebo-controlled study that will evaluate both short-term 
and long-term efficacy, as well as safety, of GED-0301 in subjects with active CD.  Efficacy will 
be based on clinical activity, as measured by the Crohn’s Disease Activity Index (CDAI) or 
average daily liquid or stool frequency and abdominal pain score, and endoscopic outcomes, as 
measured by the SES-CD.  Crohn’s Disease Activity Index, the current standard for evaluation of 
clinical disease activity, is a validated, reproducible and responsive measure of CD that has been 
widely used in clinical trials for approximately 35 years. 
 
 
  The SES-CD is a validated endoscopic index that is 
considered the most suitable endoscopic outcome measure due to its ease of use and close 
correlation with the Crohn’s Disease Endoscopic Index of Severity (CDEIS), considered the gold 
standard for endoscopic evaluation.
The primary efficacy measure will be clinical remission (defined as a CDAI score < 150) during 
the Treatment Phase at Week 12.  Key secondary efficacy measures will include: clinical 
remission at Week 52; endoscopic response-50 ([ER-50], defined as a reduction of at least 50% 
compared with baseline in SES-CD) at Week 52; clinical response (defined as a decrease from 
baseline in CDAI ≥ 100 points) at Week 12; 
 
 steroid-free clinical remission at Week 52; sustained clinical remission at both Week 12 
and Week 52; endoscopic response-25 ([ER-25], defined as a reduction of at least 25% compared 
with baseline in SES-CD) at Week 12; and the evaluation of endoscopic remission (defined as 
SES-CD ≤2) at Week 52. 
 
 
Laboratory evaluations, AEs, vital signs, electrocardiograms (ECGs), pregnancy tests and 
physical examinations will be monitored during the study to evaluate safety.

1.3.3.
Rationale for Dose, Schedule and Regimen Selection
Three oral dose regimens of GED-0301 versus placebo are being evaluated for the treatment of 
subjects with active CD:
!
GED-0301 160 mg QD for 12 weeks; followed by placebo QD for 4 weeks; followed by 
alternating GED-0301 160 mg QD for 4 weeks and placebo QD for 4 weeks, until the 
Week 52 Visit;
!
GED-0301 160 mg QD for 12 weeks; followed by placebo QD for 4 weeks; followed by
alternating GED-0301 40 mg QD for 4 weeks and placebo QD for 4 weeks, until the 
Week 52 Visit;
!
GED-0301 160 mg QD for 12 weeks; followed by continuous GED-0301 40 mg QD, 
until the Week 52 Visit.
The doses and dose regimens for this study were selected based on pre-clinical data and clinical 
data from the Phase 1 study 
 and the Phase 2 dose-finding study 
 in subjects with active CD. 
The key considerations for the selection of the appropriate dose and dosing regimens were:
1. the very low systemic exposure in animals without signs of toxicity when given orally in 
doses at least 10 times higher, by body weight, than the proposed GED-0301 160 mg QD 
dose in humans;
2. the negligible systemic exposure of GED-0301 in humans;
3. the demonstrated efficacy of GED-0301 in Phase 1 and Phase 2 studies;
4. the similar safety profile of the various GED-0301 dose treatment groups in Study 
; comparable numbers and types of TEAEs across all treatment groups, 
including the placebo treatment group were observed, with few SAEs or AEs leading to 
discontinuation of IP.
Study 
 demonstrated GED-0301 40 mg QD and 160 mg QD to be efficacious 
and safe after 2 weeks of treatment in subjects with steroid dependent or refractory CD.  
 
 
 
 
  
Therefore, these data, in addition to the similar and favorable safety profiles of GED-0301 40 mg 
QD and 160 mg QD, provide supportive evidence for the selection of 160 mg QD as the initial 
dose of GED-0301 for a 12-week treatment induction of clinical remission and endoscopic 
response
 
.  The 12-week duration was selected in order to optimize therapeutic benefit, since it is 
expected that it would take a longer duration of treatment to achieve endoscopic benefit, such as 
endoscopic response, than to achieve clinical signs and symptoms benefit or clinical remission, 
in a moderate to severe CD population.  Also, there is no consensus about the appropriate timing 
to assess the endoscopy evaluation, ranging from 10 to 26 weeks in different clinical studies

(Dave, 2012).  In addition, endoscopic assessments at time points later than 12 weeks in placebo-
controlled studies have posed the problem of limited comparative data due to the low number of 
placebo subjects remaining beyond the 12-week time point.  Hence, the 12-week time point was 
selected for the endoscopic endpoint in this study.
Three active dosing regimens will be evaluated following the initial 12-week treatment with 
GED-0301 160 mg QD, in which two different doses (160 mg QD and 40 mg QD) and different 
dosing schedules (continuous and alternating) will be evaluated in order to determine dose and 
dosing regimen that provides the best benefit to risk for subjects with active CD.
Two doses, 160 mg QD and 40 mg QD, were selected to be evaluated after the initial 160 mg 
QD 12-week treatment since the 160 mg QD dose is expected to provide the highest level of 
efficacy, and the 40 mg QD dose is the lowest efficacious dose, which has been demonstrated in 
subjects with active CD 
.  This is clinically pertinent, since subjects 
who achieve clinical response or clinical remission after the initial 12-week treatment may 
require a lower dose than that initially needed for the treatment of moderate to severe CD.
Three different dosing regimens will be evaluated: one continuous dosing regimen (GED-0301 
40 mg QD) and two alternating dosing regimens (GED-0301 40 mg QD for 4 weeks on/4 weeks 
off and GED-0301 160 mg QD for 4 weeks on/4 weeks off).  Consequently, these 3 different 
dosing regimen strategies correspond to incremental increases of 2-fold differences between each 
of the 3 arms in total IP exposure during the 40-week long-term maintenance treatment.  The 
alternating dosing regimen is supported by findings from Study 
, in which after 
2 weeks of dosing, the majority of subjects had a prolonged clinical improvement up to Week 12, 
suggesting that patients may not need continuous dosing.  This strategy may be more 
advantageous for longer term treatment in patients with CD, including the potential for a more 
favorable benefit to risk profile than a continuous dosing regimen.

OVERALL STUDY DESIGN
3.1.
Study Design
This is a Phase 3, randomized, double-blind, placebo-controlled, multicenter study to evaluate 
the efficacy and safety of 3 treatment regimens of oral GED-0301 versus placebo in subjects 
with active CD (defined by a CDAI score ≥ 220 and ≤ 450 and a total SES-CD ≥ 6 at screening, 
or the ileum segmental SES-CD ≥ 4 at screening). Approximately 1064 subjects will be 
randomized in a 1:1:1:1 ratio (266 subjects per GED-0301 arm [total 798]; 266 subjects in the 
placebo arm) to receive 1 of 3 double-blind, oral GED-0301 treatment regimens, or identically 
appearing placebo once daily (QD) for 52 weeks. The total number of subjects with a total SES-
CD score ≥ 6 is targeted to comprise approximately 80% of the study population.
Treatment assignment at baseline (Week 0/ Visit 2) will be stratified via an Interactive Web 
Response System (IWRS) based on concomitant use of corticosteroids (yes/no); concomitant use 
of immunosuppressants (eg, azathioprine [AZA], 6-mercaptopurine [6-MP], or methotrexate 
[MTX]) (yes/no), and previous exposure to biologics (ie, infliximab, adalimumab, certolizumab 
or vedolizumab) (yes/no).  The total number of subjects with previous exposure to biologics is 
targeted to comprise approximately 35% of the study population.
Subjects will receive double-blind, oral GED-0301 or identically appearing placebo QD as 
follows (Table 4):
!
GED-0301 160 mg QD for 12 weeks; followed by placebo QD for 4 weeks; followed by 
alternating GED-0301 160 mg QD for 4 weeks and placebo QD for 4 weeks, until the 
the Week 52 Visit;
!
GED-0301 160 mg QD for 12 weeks; followed by placebo QD for 4 weeks; followed by 
alternating GED-0301 40 mg QD for 4 weeks and placebo QD for 4 weeks, until the 
Week 52 Visit;
!
GED-0301 160 mg QD for 12 weeks; followed by continuous GED-0301 40 mg QD, 
until the Week 52 Visit;
!
Placebo QD until the Week 52 Visit.
Subjects who complete the GED-0301-CD-002 study at the Week 52 Visit may enter the Long-
term Active-treatment Study (GED-0301-CD-004). Subjects who meet the criteria for early 
escape beginning at the Week 12 Visit and thereafter until the Week 52 Visit, may (a) continue 
in the study at the discretion of the Investigator based on the totality of clinical data, (b) enter the 
Long-term Active-treatment Study (GED-0301-CD-004), or (c) discontinue the study.
The criteria for early escape are defined as 
 
(Table 7).
Subjects may discontinue the study at any time. Subjects who discontinue from the study at 
Week 12 (either because they meet the early escape criteria or for any other reason), will 
complete the Week 12 Visit. Subjects who prematurely discontinue from the study at any other 
time prior to the Week 52 Visit, including subjects who early escape into the Long-term Active-

scheduled as soon as possible after the last dose of IP. 
Subjects who complete the Week 52 Visit, as well as subjects who prematurely discontinue from 
the study, will have a 4-week Follow-up Visit. If the ET Visit occurs 28 days or more after the 
last dose of IP, then the Follow-up Visit is not required. 
Subjects entering the Long-term Extension Study will not have the Follow-up Visit. 
The study will be conducted in compliance with International Council for Harmonisation (ICH) 
Good Clinical Practices (GCPs) and applicable regulatory requirements.

3.1.1.
Study Duration for Subjects 
Subjects will spend up to 60 weeks in this study: up to 4 weeks in the Screening Period;
52 weeks in the Double-blind Treatment Period; and 4 weeks in the Follow-up Period.
3.1.2.
Early Termination Visit
The Early Termination Visit is based on the subject’s withdrawal from the study prior to the 
Week 52 Visit, with the exception of the Week 12 Visit (whereby the subject will complete the 
Week 12 Visit). This includes subjects who early escape into the Long-term Active-treatment 
Study after Week 12. In addition, the Investigator may discontinue the subject from the study at 
any time based on his/her assessment of clinical efficacy and/or safety. The decision to 
discontinue a subject remains the responsibility of the treating physician, and will not be delayed
or refused by the sponsor. When a subject withdraws or is discontinued from the study, every 
effort should be made to complete as many safety and efficacy assessments as reasonably 
appropriate.  Refer to the Table of Events (Table 3) for the assessments to be performed at the 
ET Visit. The ET Visit should be scheduled as soon as possible after the decision is made to 
permanently discontinue study treatment.
3.1.3.
Lost to Follow-up
Subjects will be considered lost to follow-up when they fail to attend study visits without stating 
an intention to withdraw from the study. The Investigator should show due diligence by 
documenting in the source documents the steps taken to contact the subject through multiple
telephone calls and/or emails and one registered letter. After all reasonable attempts have been 
made to contact the subject, the subject should be recorded as “lost to follow-up” in the 
electronic case report form (eCRF).
3.2.
End of Study
The End of Study is defined as either the date of the last visit of the last subject to complete the 
post-treatment follow-up or the date of receipt of the last data point from the last subject that is 
required for primary, secondary and/or exploratory analysis, as prespecified in the protocol, 
whichever is the later date.
Study completion for an individual subject is defined as reaching the Week 52 Visit.  Subjects not 
meeting this definition will be considered early termination subjects.  Subjects who discontinue 
from the study at Week 12 (either because they meet the early escape criteria or for any other 
reason) will complete the Week 12 Visit. Subjects who prematurely discontinue from the study 
at any other time prior to the Week 52 Visit, including subjects who early escape into the Long-
term Active-treatment Study, will complete the Early Termination (ET) Visit (Section 6.3). The 
ET Visit should be scheduled as soon as possible after the last dose of IP. 
Subjects who complete the Week 52 Visit, as well as subjects who prematurely discontinue from 
the study and do not enter into the Long-term Active-treatment Study, will have a 4-week 
Follow-up Visit. If the ET Visit occurs 28 days or more after the last dose of IP, then the Follow-

c At the Week 12 Visit and thereafter, until the Week 52 Visit, subjects 
 
, will be eligible to early escape into the Long-term Active-treatment Study (GED-0301-CD-
004), or may discontinue from the study.  In order to be considered for the early escape at
. Due to the delay 
in receiving the hematocrit sample results, beginning at the Week 12 Visit, and throughout the remainder of the study, the CDAI score will be evaluated by the site using the 
hematocrit results from the previous visit.
d Subjects who complete the GED-0301-CD-002 study at the Week 52 Visit, will have the option to enter the Long-term Active-treatment Study. Subjects entering the Long-term 
Extension Study will not have the Follow-up Visit.
e Pregnancy testing will be performed for FCBPs. Serum pregnancy tests will be performed at screening and urine pregnancy will be done at the remaining visits as described in 
Table 3.
f Contraception education is for Females of Child Bearing Potential (FCBP).  The Investigator will educate all FCBP about the different options of contraceptive methods and 
their correct use at Screening and Baseline Visits.  The subject will be re-educated every time her contraceptive measures/methods or ability to become pregnant changes.  The 
female subject's chosen form of contraception must be effective by the time the female subject is randomized into the study (for example, hormonal contraception should be 
initiated at least 28 days before baseline).
g Details pertaining to clinical labs are provided in Section 6.5.3.
h The electronic Subject Daily Diary (Section 6.6.1) will be provided to subjects at the Screening Visit.  Subject compliance with the completion of diary data should be assessed 
at each study visit during the Screening and Double-blind Treatment Period.
i The screening CDAI (Section 6.6.2) will be based on the Subject Daily Diary data collected during the Screening Period. Note that an abdominal exam is needed for CDAI 
assessment.
 
j The screening ileocolonoscopy should be performed following confirmation of the subject’s eligibility, based on the CDAI score.  Follow-up ileocolonoscopies will be done at 
Week 12 and Week 52 (Section 6.6.5).  The ET ileocolonoscopy will not be repeated if performed within 8 weeks of the previous ileocolonoscopy.

The screening CDAI score will be based on subject diaries collected during the 
Screening Period.  If the screening CDAI score is ≥220 and ≤ 450, the subject will 
proceed with the screening endoscopy.
!
Ileocolonoscopy is the type of endoscopy being performed during this study
(Section 6.6.5) and the SES-CD is the instrument being used to assess endoscopy 
(Section 6.6.6).
#
The screening endoscopy should be performed after confirmation of a qualifying 
CDAI score and a qualifying 7-day average of stool frequency or abdominal pain. 
#
The SES-CD is a key efficacy assessment based on endoscopic evaluation.
During the study, the SES-CD will be evaluated by both the Investigator and by a 
central reader blinded to study treatment. The SES-CD score from the central 
reader will be used to determine study eligibility:

Subjects with a SES-CD ≥6 at screening, or the ileum segmental SES-CD 
≥ 4 at screening, will be eligible for study randomization;

Subjects will be randomized upon notification of the qualifying SES-CD.
-
For subjects who will be re-screened, endoscopies performed as part of the 
original screening period, within 30 days prior to the re-screen date, and reviewed 
by a central reader, may be used to determine eligibility.
6.2.
Double-blind Treatment Period
The subject will begin study treatment upon confirmation of eligibility. For all subsequent visits
in the Double-blind Treatment Period, an administrative window of ± 3 days is permitted.  The
following evaluations will be performed at the frequency specified in Table 3. The evaluations 
should be performed prior to dosing on the visit day, unless otherwise specified.

be taken QD by the subjects.  Subjects will be instructed to take the IP in the 
morning, 30 minutes before breakfast, with a glass of water, and they will also be 
instructed to refer to the label for storage instructions. 
!
Return and count IP:  A detailed record of the doses taken and doses missed between 
visits and at visits should be recorded in the Study Drug Record eCRF and the 
subject’s source documents.  Also, a record of the overall number of tablets dispensed 
and tablets returned at each visit must be maintained in the subject’s source 
documents and recorded in the Drug Accountability eCRF.

6.2.1.
Unscheduled Visits
Unscheduled visits, if needed, may occur at any time, in particular for safety reasons (or efficacy 
reasons) as deemed necessary by the Investigator or site staff, or for any reason that the subject 
must return to study center as it pertains to the study (eg, to pick up additional or replacement 
IP).  All assessments contained in Table 3 will be made available to the site staff in the 
Unscheduled Visit eCRF, in order to perform the necessary unscheduled assessments and/or 
procedures.
6.3.
Early Termination
An Early Termination (ET) evaluation will be performed for subjects who are withdrawn from 
study treatment for any reason at any time other than the Week 12 Visit, including subjects who 
early escape into the Long-term Active-treatment Study, as soon as possible after the decision to 
permanently discontinue study treatment has been made. (Subjects who discontinue from study 
treatment at Week 12 will complete the Week 12 Visit.)

Follow-up Period 
All subjects will be followed for 28 days after the last dose of IP for AE reporting, as well as 
SAEs made known to the Investigator at any time thereafter that are suspected of being related to 
IP, as described in Section 10.1.
Subjects who complete the Week 52 Visit, as well as subjects who prematurely discontinue from 
the study, will have a 4-week Follow-up Visit. If the ET Visit occurs 28 days or more after the 
last dose of IP, then the Follow-up Visit is not required. 
Subjects entering the Long-term Extension Study will not have the Follow-up Visit. 
The following evaluations will be performed at Follow-up Visit:

Safety Assessments
6.5.1.
Physical Examination
A complete physical examination will include evaluation of the skin, nasal cavities, eyes, ears, 
abdomen, and respiratory, cardiovascular, neurological, lymphatic, and musculoskeletal systems. 
Gynecological and urogenital examinations will not be performed unless for cause.
Limited physical examinations will include evaluation of the skin, abdomen, and respiratory, 
cardiovascular, lymphatic, and musculoskeletal systems. 
An abdominal examination will be performed at every visit (including those visits at which a 
complete or partial physical examination is not being performed) to assess the presence of an 
abdominal mass for the CDAI 
 calculations.
6.5.2.
Electrocardiogram
Subjects will have a 12-lead electrocardiogram (ECG) at the frequency specified in Table 3. 
Sites are to use their own local ECG machines and the automated ECG readings will be further 
interpreted by the Investigator by clinically correlating them with the subject’s condition. The 
Investigator’s clinical interpretation will be recorded in the eCRF as: normal; abnormal, not 
clinically significant; or abnormal, clinically significant.

6.5.3.
Clinical Laboratory Assessments
Clinical laboratory evaluations will be performed by a central laboratory to include the following 
laboratory assessments performed at the frequency specified in Table 3:
!
Hematology panel will include: complete blood count (CBC) with differential, 
including red blood cell (RBC) count, hemoglobin, hematocrit, mean corpuscular 
hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), mean 
corpuscular volume (MCV), white blood cell (WBC) count (with differential), and 
platelet count.
!
Serum chemistry panel will include: total protein, albumin, calcium, phosphorous, 
glucose, total cholesterol, triglycerides, uric acid, total bilirubin, alkaline phosphatase, 
aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase (SGOT), 
alanine aminotransferase (ALT)/serum glutamic pyruvic transaminase (SGPT), 
sodium, potassium, chloride, carbon dioxide, blood urea nitrogen (BUN), creatinine, 
lactic dehydrogenase (LDH), magnesium, and complement activation (Bb, C3a and 
C5a).
!
Coagulation assessment will include: prothrombin time (PT) and activated partial 
thromboplastin time (APTT)
!
Urinalysis will be done at the central lab and will include specific gravity, pH, 
glucose, ketones, protein, blood, bilirubin, leukocyte esterase, nitrite, and 
urobilinogen. Microscopic urinalysis (bacteria, casts, crystals, epithelial cells, RBC, 
and WBC) will be performed only if the dipstick urinalysis is abnormal.
Clinical laboratory evaluations are not required to be fasting.  However, the site will record 
whether a clinical laboratory evaluation was fasting or nonfasting on the lab requisition form.
In subjects who develop new changes in liver function tests (eg, ALT or AST > 2 x the upper 
limit of normal [ULN], or Total Bilirubin [TBL] > 1.5 x ULN with normal baseline values, or    
≥ 2 x the baseline values in subjects with abnormal baseline values), repeat testing should be 
performed within 48 to 72 hours. If abnormalities persist, subjects should be evaluated for causes 
of new elevations in ALT/AST or TBL (including but not limited to tests for hepatitis, liver 
imaging, history of Gilbert’s syndrome). If there are persistent elevations in ALT or AST and/or 
TBL then close observation (including laboratory testing as appropriate) should be initiated and 
treatment could be temporarily interrupted or discontinued. Discontinuation or temporary 
interruption of study treatment should occur when criteria delineated in Appendix O are met. 
After treatment discontinuation or interruption, assessments should continue until a return of 
aminotransferases and/or TBL to normal or baseline levels, or until alternative explanation for 
the abnormal liver function tests (LFTs) is found.  
6.5.4.
Stool Assessment
Stool culture analysis and assessment of Clostridium (C.) difficile toxin will be performed at the 
Screening Visit. Subjects who are stool positive for any enteric pathogen or 
C. difficile toxin at the Screening Visit, will be excluded from the study. Subjects who are 
initially positive for C. difficile toxin may re-screen for the study 8 weeks after the start of
therapy, provided that the toxin results for C. difficile are negative.

6.5.5.
Clinically Significant Abnormal Findings
Clinically significant abnormal findings (clinical laboratory assessments, physical examination, 
ECG), with exception to the disease under study (CD), identified prior to first dose of IP will be 
recorded on the eCRF as medical history; clinically significant findings after the first dose of IP 
will be recorded as AEs.
6.5.6.
Contraception Education
Counseling about pregnancy precautions and the potential risks of fetal exposure must be 
conducted for FCBP. The Investigator will educate all FCBP about the different options of 
contraceptive methods and their correct use at the Screening and Baseline Visits.  The subject 
will be re-educated every time her contraceptive measures/methods or ability to become pregnant 
changes. The female subject's chosen form of contraception must be effective by the time the 
female subject is randomized into the study (for example, hormonal contraception should be 
initiated at least 28 days before baseline). A female of childbearing potential taking an oral 
contraceptive may need a backup or an alternative method of birth control based on Investigator 
judgment as the subject’s Crohn’s disease may potentially decrease the effectiveness of oral 
contraceptives.
There are no data on the effects of GED-0301 in pregnant women and data in animals are 
limited. Results of the animal and in vitro studies can be found in the IB. All FCBP must use 1 
of the approved contraceptive options as described in the eligibility criteria while on IP and for at 
least 28 days after administration of the last dose of the IP. At the time of study entry, and at any 
time during the study when a subject’s contraceptive measures or ability to become pregnant 
changes, the Investigator will educate the subject regarding contraception options and correct 
and consistent use of effective contraceptive methods in order to successfully prevent pregnancy. 
6.6.
Efficacy Assessments 
6.6.1.
Subject Daily Diary
During the Screening Visit, an electronic subject diary device will be given to each subject. The 
subject will receive instructions by the site personnel pertaining to the use of the electronic 
device and the importance of diary compliance throughout the study.  On an ongoing basis, site 
personnel are expected to provide education and support to the subject about the use of the 
electronic device.  In order to achieve consistent daily diary recording, the subject is instructed 
by the site personnel (at each visit if necessary) that he/she should enter diary data, each day, 
continuously throughout the study.  Site personnel must also assess the subject’s compliance 
with reporting of the daily diary data entries throughout the study.
The daily diary data will be extracted from the electronic devices and used for calculation of the 
CDAI 
 efficacy parameters.  
The electronic subject diary device will record the following information for the subject to assess 
his/her CD activity each day:

Crohn’s Disease Activity Index  
The CDAI (Appendix D) is the most commonly used measure in clinical studies evaluating the
efficacy of new therapies in CD patients with predominantly inflammatory disease (Best, 1976; 
Sandborn, 2002). The daily diary will assess how CD affects the subject’s quality of life and the 
effect of treatment on CD activity.  The CDAI consists of a questionnaire with responses scored 
numerically and weighted.  Scores (range 0 to 600) are then ranked according to severity of the 
disease.  Mild active disease is defined by a score of ≥ 150 and ≤ 219, moderate active disease is 
defined by a score of ≥ 220 and ≤ 450, and severe disease is defined as a CDAI score > 450.  
Remission is defined as a CDAI score < 150.
The CDAI consists of 8 variables:
1.
Total number of liquid or very soft stools (total for previous 7 days)
2. Abdominal pain/cramps rating (total for previous 7 days)
3. General well-being rating (total for previous 7 days)
4. Total number of listed categories the subject has experienced during the last 7 days

6.6.5.
Ileocolonoscopy 
All eligible subjects are required to have ileocolonoscopies performed during the Screening 
Period, Week 12, and Week 52. The screening ileocolonoscopy should be performed if the 
subject’s screening CDAI score is ≥ 220 and ≤ 450.  
Subjects who discontinue from the study prior to the Week 52 Visit, will have the 
ileocolonoscopy done at the ET Visit, if an ileocolonoscopy has not been performed within 8
weeks of the previous ileocolonoscopy.  
Video images of all endoscopic procedures will be captured and sent to a qualified centralized 
reader for calculation of the SES-CD to assess subject eligibility at screening, and to assess 
efficacy at Weeks 12 and 52.  Additionally, the local SES-CD will be collected from the 
investigational sites.  The site will receive a central reader SES-CD report during the Screening 
Period to determine if the SES-CD inclusion criterion is met.
For subjects at increased risk for colorectal cancer, pan-colonic surveillance with colonoscopy 
and biopsies should be done according to local guidelines.
6.6.6.
Simple Endoscopic Score for CD
The SES-CD (Appendix E) is a validated endoscopic index that closely correlates with the
Crohn’s Disease Endoscopic Index of Severity and is often considered the standard for 
endoscopic evaluation in subjects with CD.  However, the SES-CD is considered more suitable 
for clinical trials due to its simplicity and has been widely adopted for this purpose (Daperno, 
2004).
6.7.
Corticosteroid Tapering Procedure
Subjects are eligible to start corticosteroid tapering beginning at the Week 12 Visit, at the 
discretion of the Investigator, according to the following schedule:
!
For prednisone doses > 10 mg (or equivalent), each week the daily dose is to be tapered 
by 5 mg until a dose of 10 mg/day is reached, after that each week the daily dose is to be 
tapered by 2.5 mg until discontinuation.
!
For prednisone doses ≤ 10 mg (or equivalent), each week the daily dose is to be tapered 
by 2.5 mg until discontinuation. 
!
Subjects receiving budesonide should have their daily dose tapered by 3 mg every 3 
weeks.

DESCRIPTION OF STUDY TREATMENTS
7.1.
Description of Investigational Product(s)
GED-0301 will be provided as 40-mg film coated tablets. Placebo will be provided as identically 
appearing tablets.
7.2.
Treatment Administration and Schedule
Subjects will receive GED-0301(160 mg QD) or placebo during the first 12 weeks of the study, 
followed by one of 3 dose regimens of GED-0301 (40 mg QD or 160 mg QD) or placebo QD, 
until the end of the study (Week 52 Visit).  All subjects will receive 4 tablets daily during the 
Double-blind Treatment Period.  Matched placebo tablets will also be provided.  Subjects will be 
instructed to take the IP in the morning, 30 minutes before breakfast, with a glass of water. 
Treatment and administration schedule are described in Table 4.
Subjects who consent to participate in the PK substudy will be instructed to bring their IP to the 
study site where it must be administered after the collection of the predose PK blood 
sample. When the subject is providing a predose blood draw on the day of a PK substudy visit, 
the subject must be reminded to provide the date and time of his/her last dose from the day 
before the visit. 
7.2.1.
Dose Modification or Interruption 
Dose modification is not permitted.  Subjects will take their IP as determined by treatment arm. 
If a subject inadvertently does not take his or her medication for 4 or more consecutive days,
Celgene or a Celgene designee must be contacted to decide whether the subject may remain in 
the study.  Any inadvertent interruption in IP schedule will not alter the current dose or dose 
interval, nor will the length of the study be extended to account for days of IP missed.  If a 
subject is unable or unwilling to restart IP at the prior dose and/or dose interval, then the subject 
will be evaluated by the Investigator for discontinuation from the Double-blind Treatment Period
of the study, and enter the Follow-up Period.
7.2.2.
Overdose
Overdose, as defined for this protocol, applies to protocol-required dosing of the IP (GED-0301). 
Overdose for this protocol, on a per-dose basis, is defined as ingestion of more than 4 tablets of 
GED-0301 (or matching placebo) within the same calendar day whether by accident or 
intentionally.  Adverse events associated with an overdose must be collected on the AE page of 
the eCRF (see Section 10.1) for all overdosed subjects, but the overdose itself is not considered 
an AE. Other required or optional nonstudy drugs intended for prophylaxis of certain side 
effects, etc, are excluded from this definition.
7.3.
Method of Treatment Assignment
Approximately 1064 subjects will be randomized in a 1:1:1:1 ratio (266 subjects per GED-0301 
arm [total 798]; 266 subjects in the placebo arm) to receive double-blind, oral GED-0301 or

identically appearing placebo QD for 52 weeks. The total number of subjects with a total SES-
CD score ≥ 6 is targeted to comprise approximately 80% of the study population.
Subjects will receive double-blind, oral GED-0301 or identically appearing placebo daily (QD) 
as follows (Table 4):
!
GED-0301 160 mg QD for 12 weeks; followed by placebo QD for 4 weeks; followed by 
alternating GED-0301 160 mg QD for 4 weeks and placebo QD for 4 weeks, until the 
the Week 52 Visit;
!
GED-0301 160 mg QD for 12 weeks; followed by placebo QD for 4 weeks; followed by 
alternating GED-0301 40 mg QD for 4 weeks and placebo QD for 4 weeks, until the 
Week 52 Visit;
!
GED-0301 160 mg QD for 12 weeks; followed by continuous GED-0301 40 mg QD, 
until the Week 52 Visit;
!
Placebo QD until the Week 52 Visit.
Treatment assignment at baseline (Week 0/Visit 2) will be stratified via an IWRS based on 
concomitant use of corticosteroids (yes/no); concomitant use of immunosuppressants (eg, AZA, 
6-MP, or MTX) (yes/no); and previous exposure to biologics (ie, infliximab, adalimumab, 
certolizumab or vedolizumab) (yes/no).  The total number of subjects with previous exposure to 
biologics is targeted to comprise approximately 35% of the study population.
At the Week 12 Visit and thereafter, until the Week 52 Visit, subjects who meet the criteria for 
early escape (Table 7) may (a) continue in the study at the discretion of the Investigator based on 
the totality of clinical data, (b) enter the Long-term Active-treatment Study (GED-0301-CD-
004), or (c) discontinue the study. Subjects who complete the GED-0301-CD-002 Study at the 
Week 52 Visit will have the option to enter the Long-term Active-treatment Study.
Designated study personnel at the investigational sites will be assigned password-protected, 
coded identification numbers, which give them authorization to access the IWRS to randomize 
subjects.  The system will present a menu of questions by which the study personnel will identify 
the subject and confirm eligibility.  When all questions have been answered, the IWRS will 
assign a randomization identification number. Confirmation of the randomization will be sent via 
fax to the investigational site, Celgene and/or its representative.
During the study visits, the pharmacy or authorized study personnel at the investigational site 
will dispense coded IP kits in accordance with the randomization number assigned by the IWRS.

7.4.
Packaging and Labeling
GED-0301 tablets will be packaged in blister cards and or opaque high density polyethylene 
(HDPE) bottles fitted with induction seals and tamper evident child resistant caps. The label(s) 
for IP will include Sponsor name, address and telephone number, the protocol number, IP name, 
dosage form and strength (where applicable), amount of IP per container, lot number, expiry date 
(where applicable), medication identification/kit number, dosing instructions, storage conditions, 
and required caution statements and/or regulatory statements as applicable. Additional 
information may be included on the label as applicable per local regulations.
7.5.
Investigational Product Accountability and Disposal
The Investigator, or designee, is responsible for taking an inventory of each shipment of IP 
received, and comparing it with the accompanying IP shipping order/packing list.
The Investigator, or designee, will verify the accuracy of the information on the form, sign and 
date it, retain a copy in the study file, and return a copy to Celgene.
The IP must be stored as indicated on the label.  At the study site, all IP will be stored in a 
locked, safe area to prevent unauthorized access.
Celgene (or designee) will review with the Investigator and relevant site personnel the process 
for IP return, disposal, and/or destruction including responsibilities for the site versus Celgene 
(or designee). 
7.6.
Investigational Product Compliance
Study personnel will review the instructions printed on the package with the study subjects prior 
to dispensing the IP.  Investigational product will be dispensed as noted in the Table of Events 
(Table 3). The subjects will be instructed to return the IP containers, including any unused IP, to 
the study site at each visit for tablet counts and reconciliation.  Subjects will be asked whether 
they have taken their IP as instructed at each study visit.  Any problems with IP compliance will 
be reviewed with the subject.  If a subject misses 4 or more consecutive days of dosing, Celgene 
must be contacted to decide whether dosing should resume or whether the subject should be 
terminated from the study, and enter into the Follow-up Period.
Gross compliance problems (eg, missing 4 or more consecutive days of dosing or taking less 
than 75% of the doses between study visits) should be discussed with Celgene.  Compliance is 
defined as taking between 75% and 120% of dispensed IP.

CONCOMITANT MEDICATIONS AND PROCEDURES
All medications (prescription and non-prescription), treatments, and therapies taken by the 
subject from screening throughout their entire participation in the study, including those initiated 
prior to the start of the study, must be recorded on the subject’s source document and on the 
appropriate page of the eCRF.  The dose, unit, frequency, route, indication, date the medication 
was started, and date the medication was stopped (if not ongoing) must be recorded.
8.1.
Permitted Concomitant Medications and Procedures
The following medications are allowed during the study:
!
Oral aminosalicylates (SSZ or 5-ASA compounds), provided that treatment has been 
given at a stable dose for at least 2 weeks prior to the Screening Visit. The dose of 
oral aminosalicylates must remain stable through the duration of the study or early 
termination from the study.  If oral aminosalicylates have been recently discontinued, 
treatment must have been stopped at least 2 weeks prior to the Screening Visit.
!
Oral corticosteroids, provided that the dose (prednisone ≤ 20 mg/day or equivalent, 
budesonide ≤ 9 mg/day) has been stable for 3 weeks prior to the Screening Visit, and 
the dose must remain stable until the subject is eligible to start corticosteroids 
tapering (Section 6.7).  If oral corticosteroids have been recently discontinued, 
discontinuation must have been completed at least 3 weeks prior to the Screening
Visit.
!
Immunosuppressants, such as AZA, 6-MP, or MTX, provided that treatment was 
initiated ≥ 12 weeks prior to the Screening Visit, must be at a stable dose for ≥ 8 
weeks prior to the Screening Visit and remain stable for the duration of the study. If 
immunosuppressants have been recently discontinued, discontinuation must have 
been completed at least 8 weeks prior to the Screening Visit.
!
Antibiotics used for the treatment of CD (eg, ciprofloxacin, metronidazole), provided 
that the dose has been stable for at least 2 weeks prior to the Screening Visit. If 
antibiotics have been recently discontinued, discontinuation must have been 
completed at least 2 weeks prior to the Screening Visit.
!

STATISTICAL CONSIDERATIONS
9.1.
Overview
Key elements of the statistical analyses for this study are described in this section; details will be 
documented in a Statistical Analysis Plan (SAP). The statistical analyses for this study will be 
the responsibility of the Biostatistics department of the sponsor or its designee.
This study will be conducted as a double-blind study with in-house blinding procedures. For the 
purpose of the final data analysis, the official, final Week 52 database will not be unblinded until 
medical/scientific review has been conducted, protocol violations have been identified, the data
have been declared final and complete, and a SAP has been written and approved. The 
randomization schedule will be generated and implemented by the external vendor of the study 
interactive web response system (IWRS).
9.2.
Study Population Definitions
The intent-to-treat (ITT) population will be the primary population for the efficacy analysis. The 
ITT population will consist of all subjects who are randomized and receive at least 1 dose of IP.
 
 
Subjects will be included in the treatment group to which they were randomized for the efficacy 
analysis using the ITT 
 populations.
The analysis of safety data in this study will be based on the safety population, which will consist 
of all subjects who are randomized and receive at least 1 dose of IP.  Subjects will be included in 
the treatment group corresponding to the IP they actually received for the analysis using the 
safety population.
9.3.
Sample Size and Power Considerations
With a total of approximately 1064 subjects and a randomization ratio of 1:1:1:1, this study will 
randomize approximately 266 subjects into each of the three GED-0301 treatment groups and the 
placebo group.  For the efficacy analyses of the first 12 weeks of the study, the three GED-0301 
treatment groups will be pooled, due to the same treatment of GED-0301 160 mg QD received 
during the first 12 weeks, and the treatment comparisons will be made between GED-0301 160 
mg QD (approximately 798 subjects) and placebo.  For the efficacy analyses beyond Week 12, 
the treatment comparisons will be made between each of the three GED-0301 treatment groups 
and placebo.  The study sample size is driven by the comparison of each of the three GED-0301 
treatment groups with placebo with respect to the proportion of subjects with ER-50 at Week 52.  
The sample size and power calculations (not accounting for multiplicity adjustment) at a 2-sided 
significance level of 0.05 are given in Table 5.

Background and Demographic Characteristics
Subjects’ age, height, weight, and other continuous variables will be summarized using 
descriptive statistics, while sex, race and other categorical variables will be provided using 
frequency tabulations.  Medical history data will be summarized using frequency tabulations by 
Medical Dictionary for Regulatory Activities (MedDRA) system organ class and preferred term.
9.5.
Subject Disposition
Subject disposition (analysis population allocation, entered, completed, discontinued, along with 
primary reason for discontinuation) will be summarized using frequency and percent.  A 
summary of subjects enrolled by site will be provided. Protocol deviations/violations will be 
summarized using frequency tabulations.
9.6.
Efficacy Analysis
For the efficacy analyses of the first 12 weeks of the study, the three GED-0301 treatment groups 
will be pooled, due to the same treatment of GED-0301 160 mg QD received during the first 12 
weeks, and the treatment comparisons will be made between GED-0301 160 mg QD and 
placebo.  For the efficacy analyses beyond Week 12, the treatment comparisons will be made 
between each of the three GED-0301 treatment groups and placebo.
9.6.1.
Statistical Methods
Binary endpoints will be analyzed by the Cochran-Mantel-Haenszel (CMH) test stratified by the 
randomization stratification factors.  Subjects who have insufficient data for response 
determination for the time point under consideration will be considered nonresponders for that 
time point.

9.6.2.
Multiplicity
Formal statistical tests are planned for the primary and secondary efficacy endpoints.  In order to 
control the family-wise Type I error rate at the 0.05 level, formal statistical tests will be carried 
out using a gatekeeping closed testing procedure; details of this procedure, including the 
endpoints subjected to this procedure and their hierarchy, will be specified in the SAP.
For formal statistical tests that are planned but not performed as a result of the multiplicity 
adjustment procedure, as well as for any other comparisons that are not subjected to multiplicity 
adjustment, nominal 2-sided p-values (without adjustment for multiplicity) will be provided as a 
measure of the strength of association between the endpoint and the treatment effect rather than 
formal tests of hypotheses.
 
 
9.7.
Safety Analysis
Safety and tolerability will be assessed by clinical review of all relevant parameters including 
treatment-emergent adverse events (TEAEs), laboratory tests, vital signs, weight, and ECGs.  No 
inferential testing for statistical significance will be performed.
TEAEs will be classified using the MedDRA classification system.  All TEAEs will be 
summarized by system organ class, preferred term, severity, and relationship to IP.  TEAEs
leading to death or to discontinuation from treatment and serious TEAEs will also be tabulated.  
In the by-subject analysis, a subject having the same event more than once will be counted only 
once and by greatest severity.
Laboratory, vital signs, weight, and ECG data will be summarized descriptively by time point.  
In addition, shift tables showing the number of subjects with values low, normal, and high 
compared to the normal ranges at baseline versus postbaseline will be provided for laboratory 
tests.
9.8.
Interim Analysis
No interim analysis is planned for this study.

Internal Celgene Safety Monitoring During the GED-0301 Program: Role of the 
Safety Management Team 
In addition to ongoing safety monitoring conducted by Investigators and individual study 
personnel, cumulative and interval blinded AEs, SAEs, discontinuations due to AEs, and 
abnormal laboratory findings will be reviewed internally by the Safety Management Team 
(SMT). The review will follow the Council for International Organizations for Medical 
Sciences, Working Group VI (CIOMS VI) recommendations. The SMT is comprised of lead 
representatives from multiple Celgene functions engaged in the GED-0301 development 
program. The scope, conduct, processes, and accountabilities of the SMT are specified in the 
SMT charter. 
9.9.4.
External Safety Monitoring: Role of the Independent DMC
Safety monitoring will also be performed by an external, independent Data Monitoring 
Committee (DMC). The DMC will review unblinded data to evaluate safety during the 
study. The DMC is comprised of independent physician experts and a statistician for whom 
there is no identified conflict of interest. The DMC will be convened regularly, at least once a 
year, or ad hoc at the request of the SMT. The DMC scope, conduct, processes, and 
accountabilities are specified in a charter.

ADVERSE EVENTS
10.1.
Monitoring, Recording and Reporting of Adverse Events
An AE is any noxious, unintended, or untoward medical occurrence that may appear or worsen 
in a subject during the course of a study. It may be a new intercurrent illness, a worsening 
concomitant illness, an injury, or any concomitant impairment of the subject’s health, including 
laboratory test values (as specified by the criteria in Section 10.3), regardless of etiology. Any 
worsening (ie, any clinically significant adverse change in the frequency or intensity of a pre-
existing condition) should be considered an AE.  A diagnosis or syndrome should be recorded on 
the AE page of the eCRF rather than the individual signs or symptoms of the diagnosis or 
syndrome. 
Abuse, withdrawal, sensitivity or toxicity to an investigational product should be reported as an 
AE. Overdose, accidental or intentional, whether or not it is associated with an AE should be 
reported on the overdose eCRF. (See Section 7.2.2 for the definition of overdose.) Any sequela 
of an accidental or intentional overdose of an investigational product should be reported as an 
AE on the AE eCRF. If the sequela of an overdose is an SAE, then the sequela must be reported 
on an SAE report form and on the AE eCRF. The overdose resulting in the SAE should be 
identified as the cause of the event on the SAE report form and eCRF but should not be reported 
as an SAE itself.
In the event of overdose, the subject should be monitored as appropriate and should receive 
supportive measures as necessary. Actual treatment should depend on the severity of the clinical 
situation and the judgment and experience of the treating physician.
All subjects will be monitored for AEs during the study.  Assessments may include monitoring 
of any or all of the following parameters:  the subject’s clinical symptoms, laboratory, 
pathological, radiological or surgical findings, physical examination findings, or findings from 
other tests and/or procedures.
All AEs will be recorded by the Investigator from the time the subject signs informed consent 
until 28 days after the last dose of IP as well as those SAEs made known to the Investigator at 
any time thereafter that are suspected of being related to IP.  AEs and SAEs will be recorded on 
the AE page of the eCRF and in the subject’s source documents.  All SAEs must be reported to 
Celgene Drug Safety within 24 hours of the Investigator’s knowledge of the event by facsimile, 
or other appropriate method, using the SAE Report Form, or approved equivalent form. 
10.2.

Requires inpatient hospitalization or prolongation of existing hospitalization 
(hospitalization is defined as an inpatient admission, regardless of length of stay);
!
Results in persistent or significant disability/incapacity (a substantial disruption of the 
subject’s ability to conduct normal life functions);
!
Is a congenital anomaly/birth defect;
!
Constitutes an important medical event.
Important medical events are defined as those occurrences that may not be immediately life-
threatening or result in death, hospitalization, or disability, but may jeopardize the subject or 
require medical or surgical intervention to prevent one of the other outcomes listed above.  
Medical and scientific judgment should be exercised in deciding whether such an AE should be 
considered serious.
Events not considered to be SAEs are hospitalizations for:
!
a standard procedure for protocol therapy administration.  However, hospitalization or 
prolonged hospitalization for a complication of therapy administration will be 
reported as an SAE. 
!
routine treatment or monitoring of the studied indication not associated with any 
deterioration in condition.
!
a procedure for protocol/disease-related investigations (eg, surgery, scans, endoscopy, 
sampling for laboratory tests, bone marrow sampling).  However, hospitalization or 
prolonged hospitalization for a complication of such procedures remains a reportable 
SAE.
!
hospitalization or prolongation of hospitalization for technical, practical, or social 
reasons, in absence of an AE.
!
a procedure that is planned (ie, planned prior to start of treatment on study); must be 
documented in the source document and the eCRF.  Hospitalization or prolonged 
hospitalization for a complication remains a reportable SAE.
!
an elective treatment of or an elective procedure for a pre-existing condition, 
unrelated to the studied indication, that has not worsened from baseline. 
!
emergency outpatient treatment or observation that does not result in admission, 
unless fulfilling other seriousness criteria above.
If an AE is considered serious, both the AE page/screen of the eCRF and the SAE Report Form 
must be completed.
For each SAE, the Investigator will provide information on severity, start and stop dates, 
relationship to the IP, action taken regarding the IP, and outcome.
10.2.2.
Severity/Intensity
For both AEs and SAEs, the Investigator must assess the severity/ intensity of the event.

The term “severe” is often used to describe the intensity of a specific event (as in mild, moderate 
or severe myocardial infarction); the event itself, however, may be of relatively minor medical 
significance (such as severe headache).  This criterion is not the same as “serious” which is 
based on subject/event outcome or action criteria associated with events that pose a threat to a 
subject’s life or functioning.  
Seriousness, not severity, serves as a guide for defining regulatory obligations.
10.2.3.
Causality
The Investigator must determine the relationship between the administration of the IP and the 
occurrence of an AE/SAE as Not Suspected or Suspected as defined below:
Not suspected:
a causal relationship of the adverse event to IP administration is 
unlikely or remote, or other medications, therapeutic
interventions, or underlying conditions provide a sufficient 
explanation for the observed event.
Suspected:
there is a reasonable possibility that the administration of IP 
caused the adverse event.  ‘Reasonable possibility’ means there 
is evidence to suggest a causal relationship between the IP and 
the adverse event.

GED-0301-CD-002 Amendment 3 Final: 15 Aug 2017
Causality should be assessed and provided for every AE/SAE based on currently available 
information.  Causality is to be reassessed and provided as additional information becomes 
available.
If an event is assessed as suspected of being related to a comparator, ancillary or additional IP 
that has not been manufactured or provided by Celgene, please provide the name of the 
manufacturer when reporting the event.
10.2.4.
Duration
For both AEs and SAEs, the Investigator will provide a record of the start and stop dates of the 
event.
10.2.5.
Action Taken
The Investigator will report the action taken with IP as a result of an AE or SAE, as applicable 
(eg, discontinuation, interruption, or dose reduction of IP, as appropriate) and report if 
concomitant and/or additional treatments were given for the event. 
10.2.6.
Outcome
The Investigator will report the outcome of the event for both AEs and SAEs.
All SAEs that have not resolved upon discontinuation of the subject’s participation in the study 
must be followed until recovered (returned to baseline), recovered with sequelae, or death (due to 
the SAE).
10.3.
Abnormal Laboratory Values
An abnormal laboratory value is considered to be an AE if the abnormality:
!
results in discontinuation from the study;
!
requires treatment, modification/ interruption of IP dose, or any other therapeutic 
intervention; or
!
is judged to be of significant clinical importance, eg, one that indicates a new disease 
process and/or organ toxicity, or is an exacerbation or worsening of an existing 
condition.
Regardless of severity grade, only laboratory abnormalities that fulfill a seriousness criterion 
need to be documented as a serious adverse event.
If a laboratory abnormality is one component of a diagnosis or syndrome, then only the diagnosis 
or syndrome should be recorded on the AE page/screen of the eCRF.  If the abnormality was not 
a part of a diagnosis or syndrome, then the laboratory abnormality should be recorded as the AE. 
If possible, the laboratory abnormality should be recorded as a medical term and not simply as an 
abnormal laboratory result (eg, record thrombocytopenia rather than decreased platelets).
10.4.
Pregnancy
All pregnancies or suspected pregnancies occurring in a female subject of childbearing potential 
are immediately reportable events.

10.4.1.
Females of Childbearing Potential
Pregnancies and suspected pregnancies (including a positive pregnancy test regardless of age or 
disease state) of a female subject occurring while the subject is on IP, or within at least 28 days
of the subject’s last dose of IP, are considered immediately reportable events.  Investigational 
product is to be discontinued immediately.  The pregnancy, suspected pregnancy, or positive 
pregnancy test must be reported to Celgene Drug Safety immediately by facsimile, or other 
appropriate method, using the Pregnancy Initial Report Form, or approved equivalent form.
The female subject may be referred to an obstetrician-gynecologist or another appropriate 
healthcare professional for further evaluation.
The Investigator will follow the female subject until completion of the pregnancy, and must 
notify Celgene Drug Safety immediately about the outcome of the pregnancy (either normal or 
abnormal outcome) using the Pregnancy Follow-up Report Form, or approved equivalent form.
If the outcome of the pregnancy was abnormal (eg, spontaneous abortion), the Investigator 
should report the abnormal outcome as an AE.  If the abnormal outcome meets any of the serious 
criteria, it must be reported as an SAE to Celgene Drug Safety by facsimile, or other appropriate 
method, within 24 hours of the Investigator’s knowledge of the event using the SAE Report 
Form, or approved equivalent form.
All neonatal deaths that occur within 28 days of birth should be reported, without regard to 
causality, as SAEs.  In addition, any infant death after 28 days that the Investigator suspects is 
related to the in utero exposure to the IP should also be reported to Celgene Drug Safety by 
facsimile, or other appropriate method, within 24 hours of the Investigator’s knowledge of the 
event using the SAE Report Form, or approved equivalent form.
10.5.
Reporting of Serious Adverse Events
Any AE that meets any criterion for an SAE requires the completion of an SAE Report Form in 
addition to being recorded on the AE page/screen of the eCRF.  All SAEs must be reported to 
Celgene Drug Safety within 24 hours of the Investigator’s knowledge of the event by facsimile, 
or other appropriate method (eg, via email), using the SAE Report Form, or approved equivalent 
form.  This instruction pertains to initial SAE reports as well as any follow-up reports.
The Investigator is required to ensure that the data on these forms is accurate and consistent.  
This requirement applies to all SAEs (regardless of relationship to IP) that occur during the study 
(from the time the subject signs informed consent until 28 days after the last dose of IP) or any 
SAE made known to the Investigator at anytime thereafter that are suspected of being related to 
IP.  Serious adverse events occurring prior to treatment (after signing the ICF) will be captured.
The SAE report should provide a detailed description of the SAE and include a concise summary 
of hospital records and other relevant documents.  If a subject died and an autopsy has been 
performed, copies of the autopsy report and death certificate are to be sent to Celgene Drug 
Safety as soon as these become available.  Any follow-up data should be detailed in a subsequent 
SAE Report Form, or approved equivalent form, and sent to Celgene Drug Safety.  
Where required by local legislation, the Investigator is responsible for informing the Institutional 
Review Board/Ethics Committee (IRB/EC) of the SAE and providing them with all relevant

information on file including correspondence with Celgene and the IRB/EC.
10.5.1.
Safety Queries
Queries pertaining to SAEs will be communicated from Celgene Drug Safety to the site via 
facsimile or electronic mail.  The response time is expected to be no more than five (5) business 
days.  Urgent queries (eg, missing causality assessment) may be handled by phone.
10.6.
Expedited Reporting of Adverse Events
For the purpose of regulatory reporting, Celgene Drug Safety will determine the expectedness of 
events suspected of being related to GED-0301 based on the Investigator Brochure.
In the United States, all suspected unexpected serious adverse reactions (SUSARs) will be 
reported in an expedited manner in accordance with 21 CFR 312.32.
For countries within the European Economic Area (EEA), Celgene or its authorized 
representative will report in an expedited manner to Regulatory Authorities and Ethics 
Committees concerned, suspected unexpected serious adverse reactions (SUSARs) in accordance 
with Directive 2001/20/EC and the Detailed Guidance on collection, verification and 
presentation of adverse reaction reports arising from clinical trials on investigational products for 
human use (ENTR/CT3) and also in accordance with country-specific requirements.  
Celgene or its authorized representative shall notify the Investigator of the following information 
!
Any AE suspected of being related to the use of IP in this study or in other studies 
that is both serious and unexpected (ie, SUSAR);
!
Any finding from tests in laboratory animals that suggests a significant risk for 
human subjects including reports of mutagenicity, teratogenicity, or carcinogenicity.
Where required by local legislation, the Investigator shall notify his/her IRB/EC promptly of 
these new serious and unexpected AE(s) or significant risks to subjects.
The Investigator must keep copies of all pertinent safety information on file including 
correspondence with Celgene and the IRB/EC.  (See Section 14.3 for record retention 
information).
Celgene Drug Safety Contact Information:
For Celgene Drug Safety contact information, please refer to the Serious Adverse Event Report

DISCONTINUATIONS
Subjects can discontinue at any time at their own request or at the discretion of the investigator. 
Reasons for discontinuation of a subject from treatment include but are not limited to:
!
Any safety reason (eg, adverse event, laboratory abnormality) which in the opinion of 
the Investigator or the sponsor (or designee) places the subject at significant risk 
should he/she continue participating in the study. Please refer to Appendix O for 
discontinuation criteria related to liver function test abnormalities.
!
Surgical procedures related to Crohn’s disease (eg, intestinal resection, ileostomy, 
colostomy, intra-abdominal surgery related to CD)
!
Initiation of a biologic medication (eg, TNF-α blockers, natalizumab, vedolizumab, 
ustekinumab)
!
Initiation of immunomodulatory agents for the treatment of CD, such as
mycophenolic acid, tacrolimus, sirolimus, cyclosporine, thalidomide or apheresis (eg, 
Adacolumn®).
11.1.
Treatment Discontinuation
The following events are considered sufficient reasons for discontinuing a subject from the 
investigational product(s):
!
Lack of efficacy
!
Adverse Event
!
Withdrawal by subject
!
Death
!
Lost to follow-up
!
Other (to be specified in the eCRF)
!
Pregnancy
The reason for discontinuation of treatment should be recorded in the eCRF and in the source 
documents.
The decision to discontinue a subject from treatment remains the responsibility of the treating 
physician, which will not be delayed or refused by the Sponsor.  However, prior to discontinuing 
a subject, the Investigator may contact the Medical Monitor and forward appropriate supporting 
documents for review and discussion.

EMERGENCY PROCEDURES
12.1.
Emergency Contact
In emergency situations, the Investigator should contact the responsible Clinical Research 
Physician/Medical Monitor or designee by telephone at the number(s) listed on the Emergency 
Contact Information page of the protocol (after title page).
In the unlikely event that the Clinical Research Physician/Medical Monitor or designee cannot be 
reached, please contact the global Emergency Call Center by telephone at the number listed on 
the Emergency Contact Information page of the protocol (after title page). This global 
Emergency Call Center is available 24 hours a day and 7 days a week. The representatives are 
responsible for obtaining your call-back information and contacting the on-call Celgene/contract 
research organization Medical Monitor, who will then contact you promptly.
Note: The back-up 24-hour global emergency contact call center should only be used if you are 
not able to reach the Clinical Research Physician(s) or Medical Monitor or designee for 
emergency calls. 
12.2.
Emergency Identification of Investigational Products
The blind must not be broken during the course of the study unless, in the opinion of the 
Investigator, it is absolutely necessary to safely treat the subject.  If it is medically imperative to 
know what IP the subject is receiving, IP should be temporarily discontinued if, in the opinion of 
the Investigator, continuing IP can negatively affect the outcome of the subject’s treatment.
The decision to break the blind in emergency situations remains the responsibility of the treating 
physician, which will not be delayed or refused by the sponsor.  However, the Investigator may 
contact the Medical Monitor prior to breaking the blind to discuss unblinding, mainly in the 
interest of the subject. The Investigator should ensure that the code is broken only in accordance 
with the protocol. The Investigator should promptly notify the Medical Monitor of the 
emergency unblinding and the reason for breaking the blind, which should be clearly 
documented by the Investigator in the subject’s source documentation. Emergency unblinding 
should only be performed by the Investigator through the IWRS by using an emergency 
unblinding personal identification number (PIN), and the Investigator should call IWRS for 
unblinded dose information.

REGULATORY CONSIDERATIONS
13.1.
Good Clinical Practice
The procedures set out in this study protocol pertaining to the conduct, evaluation, and 
documentation of this study are designed to ensure that Celgene, its authorized representative, 
and Investigator abide by Good Clinical Practice (GCP), as described in International Council for
Harmonisation (ICH) Guideline E6 and in accordance with the general ethical principles outlined 
in the Declaration of Helsinki. The study will receive approval from an IRB/EC prior to 
commencement. The Investigator will conduct all aspects of this study in accordance with 
applicable national, state, and local laws of the pertinent regulatory authorities.
13.2.
Investigator Responsibilities
Investigator responsibilities are set out in the ICH Guideline for Good Clinical Practice and in 
the local regulations.  Celgene staff or an authorized representative will evaluate and approve all 
Investigators who in turn will select their staff.
The Investigator should ensure that all persons assisting with the study are adequately informed 
about the protocol, amendments, study treatments, as well as study-related duties and functions, 
including obligations of confidentiality of Celgene information. The Investigator should maintain 
a list of Sub-investigators and other appropriately qualified persons to whom he or she has 
delegated significant study-related duties.
The Investigator is responsible for keeping a record of all subjects who sign an informed consent 
form (ICF) and are screened for entry into the study.  Subjects who fail screening must have the 
reason(s) recorded in the subject’s source documents.
The Investigator, or a designated member of the Investigator’s staff, must be available during 
monitoring visits to review data, resolve queries and allow direct access to subject records (eg, 
medical records, office charts, hospital charts, and study-related charts) for source data 
verification.  The Investigator must ensure timely and accurate completion of eCRFs and queries.
The information contained in the protocol and amendments (with the exception of the 
information provided by Celgene on public registry websites) is considered Celgene confidential 
information.  Only information that is previously disclosed by Celgene on a public registry 
website may be freely disclosed by the Investigator or its institution, or as outlined in the Clinical 
Trial Agreement.  Celgene protocol, amendment and IB information is not to be made publicly 
available (for example on the Investigator’s or their institution’s website) without express written 
approval from Celgene.  Information proposed for posting on the Investigator’s or their 
institution’s website must be submitted to Celgene for review and approval, providing at least 5 
business days for review.
At the time results of this study are made available to the public, Celgene will provide 
Investigators with a summary of the results that is written for the lay person. The Investigator is 
responsible for sharing these results with the subject and/or their caregiver as agreed by the 
subject.

13.3.
Subject Information and Informed Consent
The Investigator must obtain informed consent of a subject and/or a subject’s legal representative 
prior to any study related procedures.
Documentation that informed consent occurred prior to the study subject’s entry into the study 
and of the informed consent process should be recorded in the study subject’s source documents 
including the date.  The original ICF signed and dated by the study subject and by the person 
consenting the study subject prior to the study subject’s entry into the study, must be maintained 
in the Investigator’s study files and a copy given to the study subject. In addition, if a protocol is 
amended and it impacts on the content of the informed consent, the ICF must be revised.  Study 
subjects participating in the study when the amended protocol is implemented must be re-
consented with the revised version of the ICF.  The revised ICF signed and dated by the study 
subject and by the person consenting the study subject must be maintained in the Investigator’s 
study files and a copy given to the study subject.
13.4.
Confidentiality
Celgene affirms the subject's right to protection against invasion of privacy and to be in 
compliance with ICH and other local regulations (whichever is most stringent). Celgene requires 
the Investigator to permit Celgene's representatives and, when necessary, representatives from 
regulatory authorities, to review and/or copy any medical records relevant to the study in 
accordance with local laws.
Should direct access to medical records require a waiver or authorization separate from the 
subject’s signed ICF, it is the responsibility of the Investigator to obtain such permission in 
writing from the appropriate individual.
13.5.
Protocol Amendments
Any amendment to this protocol must be approved by the Celgene Clinical Research 
Physician/Medical Monitor.  Amendments will be submitted to the IRB/EC for written approval.  
Written approval must be obtained before implementation of the amended version occurs.  The 
written signed approval from the IRB/EC should specifically reference the Investigator name, 
protocol number, study title and amendment number(s) that is applicable. Amendments that are 
administrative in nature do not require IRB/IEC approval but will be submitted to the IRB/IEC 
for information purposes.
13.6.
Institutional Review Board/Independent Ethics Committee Review 
and Approval
Before the start of the study, the study protocol, ICF, and any other appropriate documents will 
be submitted to the IRB/EC with a cover letter or a form listing the documents submitted, their 
dates of issue, and the site (or region or area of jurisdiction, as applicable) for which approval is 
sought. If applicable, the documents will also be submitted to the authorities in accordance with 
local legal requirements.
IP can only be supplied to an Investigator by Celgene or its authorized representative after 
documentation on all ethical and legal requirements for starting the study has been received by

Celgene or its authorized representative. This documentation must also include a list of the 
members of the IRB/EC and their occupation and qualifications. If the IRB/EC will not disclose 
the names, occupations and qualifications of the committee members, it should be asked to issue 
a statement confirming that the composition of the committee is in accordance with GCP. For 
example, the IRB General Assurance Number may be accepted as a substitute for this list. 
Formal approval by the IRB/EC should mention the protocol title, number, amendment number 
(if applicable), study site (or region or area of jurisdiction, as applicable), and any other 
documents reviewed. It must mention the date on which the decision was made and must be 
officially signed by a committee member. Before the first subject is enrolled in the study, all 
ethical and legal requirements must be met.
The IRB/EC and, if applicable, the authorities, must be informed of all subsequent protocol 
amendments in accordance with local legal requirements. Amendments must be evaluated to 
determine whether formal approval must be sought and whether the ICF should also be revised.
The Investigator must keep a record of all communication with the IRB/EC and, if applicable, 
between a Coordinating Investigator and the IRB/EC. This statement also applies to any 
communication between the Investigator (or Coordinating Investigator, if applicable) and 
regulatory authorities.
Any advertisements used to recruit subjects for the study must be reviewed by Celgene and the 
IRB/EC prior to use.
13.7.
Ongoing Information for Institutional Review Board/ Ethics 
Committee
If required by legislation or the IRB/EC, the Investigator must submit to the IRB/EC:
!
Information on serious or unexpected adverse events as soon as possible; 
!
Periodic reports on the progress of the study;
!
Deviations from the protocol or anything that may involve added risk to subjects.
13.8.
Termination of the Study
Celgene reserves the right to terminate this study prematurely at any time for reasonable medical 
or administrative reasons. Any premature discontinuation will be appropriately documented 
according to local requirements (eg, IRB/EC, regulatory authorities, etc).  In addition, the 
Investigator or Celgene has the right to discontinue a single site at any time during the study for 
medical or administrative reasons such as: 
!
Unsatisfactory enrollment;
!
GCP noncompliance;
!
Inaccurate or incomplete data collection;
!
Falsification of records;
!
Failure to adhere to the study protocol.

DATA HANDLING AND RECORDKEEPING 
14.1.
Data/Documents
The Investigator must ensure that the records and documents pertaining to the conduct of the 
study and the distribution of the investigational product are complete, accurate, filed and 
retained.  Examples of source documents include: hospital records; clinic and office charts; 
laboratory notes; memoranda; subject’s diaries or evaluation checklists; dispensing records; 
recorded data from automated instruments; copies or transcriptions certified after verification as

operating procedures (SOPs). This data will be electronically verified through use of 
programmed edit checks specified by the clinical team.  Discrepancies in the data will be brought 
to the attention of the clinical team, and investigational site personnel, if necessary.  Resolutions 
to these issues will be reflected in the database.  An audit trail within the system will track all 
changes made to the data.
14.3.
Record Retention
Essential documents must be retained by the Investigator according to the period of time outlined 
in the clinical trial agreement. The Investigator must retain these documents for the time period 
described above or according to local laws or requirements, whichever is longer. Essential 
documents include, but are not limited to, the following:
!
Signed ICFs for all subjects;
!
Subject identification code list, screening log (if applicable), and enrollment log;
!
Record of all communications between the Investigator and the IRB/EC;
!
Composition of the IRB/EC;
!
Record of all communications between the Investigator, Celgene, and their authorized 
representative(s);
!
List of Sub-investigators and other appropriately qualified persons to whom the 
Investigator has delegated significant study-related duties, together with their roles in 
the study, curriculum vitae, and their signatures;
!
Copies of CRFs (if paper) and of documentation of corrections for all subjects;
!

QUALITY CONTROL AND QUALITY ASSURANCE
All aspects of the study will be carefully monitored by Celgene or its authorized representative 
for compliance with applicable government regulations with respect to current GCP and SOPs.
15.1.
Study Monitoring and Source Data Verification
Celgene ensures that appropriate monitoring procedures are performed before, during and after 
the study.  All aspects of the study are reviewed with the Investigator and the staff at a study 
initiation visit and/or at an Investigators’ Meeting.  Prior to enrolling subjects into the study, a 
Celgene representative will review the protocol, eCRFs, procedures for obtaining informed 
consent, record keeping, and reporting of AEs/SAEs with the Investigator.  Monitoring will 
include on-site visits with the Investigator and his/her staff as well as any appropriate 
communications by mail, email, fax, or telephone.  During monitoring visits, the facilities, 
investigational product storage area, eCRFs, subject’s source documents, and all other study 
documentation will be inspected/reviewed by the Celgene representative in accordance with the 
Study Monitoring Plan.
Accuracy will be checked by performing source data verification that is a direct comparison of 
the entries made onto the eCRFs against the appropriate source documentation.  Any resulting 
discrepancies will be reviewed with the Investigator and/or his/her staff.  Any necessary 
corrections will be made directly to the eCRFs or via queries by the Investigator and/or his/her 
staff. Monitoring procedures require that informed consents, adherence to inclusion/exclusion 
criteria and documentation of SAEs and their proper recording be verified.  Additional 
monitoring activities may be outlined in a study-specific monitoring plan.
15.2.
Audits and Inspections
In addition to the routine monitoring procedures, a Good Clinical Practice Quality Assurance 
unit exists within Celgene.  Representatives of this unit will conduct audits of clinical research 
activities in accordance with Celgene SOPs to evaluate compliance with Good Clinical Practice 
guidelines and regulations.
The Investigator is required to permit direct access to the facilities where the study took place, 
source documents, eCRFs and applicable supporting records of study subject participation for 
audits and inspections by IRB/ECs, regulatory authorities (eg, Federal Drug Administration 
[FDA], European Medicines Agency [EMA]), Health Canada and company authorized 
representatives.  The Investigator should make every effort to be available for the audits and/or 
inspections.  If the Investigator is contacted by any regulatory authority regarding an inspection, 
he/she should contact Celgene immediately.

TEST ABNORMALITIES
Criteria for discontinuing or temporarily interrupting study treatment:
!
When the baseline values were < 2 x upper limit of normal (ULN), discontinue if alanine 
aminotransferase (ALT) or aspartate aminotransferase (AST) increases to > 5 x baseline 
values.
!
When the baseline values were ≥2 x ULN but < 5 x ULN, discontinue if ALT or AST 
increases to > 3 x baseline values.
!
When ALT or AST increase > 2 x baseline values AND the increase is accompanied by a 
concomitant total bilirubin (TBL) increase to > 2 x baseline values.
!
All patients who develop symptoms consistent with hepatic injury (eg, appearance of fatigue, 
nausea, vomiting, right upper quadrant pain or tenderness, fever, rash, and/or eosinophilia [>
5%]) in combination with elevations in liver enzymes.

JUSTIFICATION FOR AMENDMENT
Significant changes included in this amendment are summarized below:

Section(s) Affected
Change / Justification
Endpoint 
Harmonization  
Protocol Summary, 
(Endpoints, Statistical 
Methods); Table 2
(Study Endpoints); 
Section 9.3 (Statistical 
Considerations, Sample 
Size and Power 
Considerations, Table 5
[previously Table 7])
The primary purpose of this protocol amendment is to 
harmonize and reprioritize the order of endpoints 
based on regulatory agency feedback. There is now 
one set of endpoints for all regions. The primary 
efficacy measure will be clinical remission (defined as 
a Crohn’s Disease Activity Index [CDAI] score < 
150) at Week 12.  Key secondary efficacy measures 
will include: clinical remission at Week 52; 
endoscopic response-50 (ER-50, defined as a 
reduction of at least 50% compared with baseline in 
the Simple Endoscopic Score for Crohn’s Disease 
[SES-CD]) at Week 52; clinical response (defined as 
a decrease from baseline in CDAI ≥ 100 points) at 
Week 12;
 
 steroid-free clinical remission at 
Week 52; sustained clinical remission at both Week 
12 and Week 52; endoscopic response-25 (ER-25, 
defined as a reduction of at least 25% compared with
baseline in SES-CD) at Week 12; and the evaluation 
of endoscopic remission (defined as SES-CD ≤ 2) at 
Week 52.  
 
 
 
 
 
The statistical sections were revised to support the 
hierarchy of endpoints as listed above.
Monitoring of liver 
function tests
Clinical Laboratory 
Assessments (Section 
6.5.3); Criteria for 
Temporary Interruption 
of IP or Study 
Discontinuation Based 
on Liver Function Test 
Abnormalities 
(Appendix O) 
Additional guidance has been added for subjects who 
develop new changes in liver function tests, including 
but not limited to repeat testing, evaluation for cause, 
and close observation. Criteria have also been 
provided to consider IP interruption or study 
discontinuation.
 
 
Discontinuation

The reasons for treatment and study discontinuation 
were updated to include lack of efficacy.
The amendment also includes several other minor clarifications and corrections:

Efficacy 
Measurements and 
Outcomes
Section 1.3.2 
(Rationale for the Study 
Design); Appendix B 
(Definitions for
Efficacy Outcomes,
Table 7 [previously 
Table 9])
For simplification purposes, the definition of clinical 
remission is CDAI < 150 only. While clinical 
symptoms of stool frequency ≤3 and abdominal pain
score ≤1 are still important endpoints to consider, the 
term “clinical remission” is now specific to CDAI.
The title of Appendix B was changed to match the 
table title.
Exclusion Criteria
Section 4.3 (Exclusion 
Criteria)
Exclusion Criterion 24 was revised to further specify 
exceptions to the malignancy exclusion.
Ileocolonoscopy at 
Early Termination
Section 5 (Table of 
Events, Table 3 
[previously Table 5]); 
Section 6.6.5 
(Ileocolonoscopy)
Text was revised such that an ileocolonoscopy does 
not need to be performed at Early Termination if done 
within 8 weeks of the previous ileocolonoscopy.
Visit Windows 
Section 5 (Table of 
Events, Table 3 
[previously Table 5])
A 3-day visit window was added for the follow up 
visit, and the 3-day visit window was removed for the 
baseline visit. These updates were made to reflect the 
intended variance for visit scheduling.
 
 
 
Rescreening 
requests
Section 6.1 (Screening 
period)
Text was clarified to indicate that subjects may be 
allowed to rescreen with approval by the sponsor or 
designee.
Clostridium 
difficile testing
Section 6.1.1 
(Screening Visit); 
Section 6.5.4 (Stool 
Assessment)
The process for C. difficile treatment and testing was
revised as 2 months of consecutive negative toxin 
results are not necessary before rescreening. Subjects 
who test positive for the C. difficile toxin may

GED-0301-CD-002 Amendment # 2 Global Final:  25 Oct 2016
1.
JUSTIFICATION FOR AMENDMENT
Significant changes included in this amendment are summarized below:
Subject
Section(s) Affected
Change / Justification
Endpoint Hierarchy  Protocol Summary, 
(Endpoints, Statistical 
Methods); Tables 2-4 
(Study Endpoints); 
Section 9.3 (Statistical 
Considerations, Sample 
Size and Power 
Considerations, Table 
7)
The primary purpose of this protocol amendment is to prioritize the evaluation of clinical 
remission and endoscopic outcomes as primary and key secondary endpoints. Endpoints are now 
listed by two regions (United States [US] and Rest of World [ROW]) based on feedback from 
regulatory authorities. The primary efficacy measure will be clinical remission (defined as an 
average daily liquid or soft stool frequency ≤ 3 AND abdominal pain score ≤ 1 [US] or a Crohn’s 
Disease Activity Index (CDAI) score < 150 [ROW]) at Week 12.  The key secondary efficacy 
measures will include: the evaluation of endoscopic remission (defined as SES-CD ≤ 2) at Week 
52; clinical remission based on CDAI score at Week 12 (US only); clinical remission (based on 
stool frequency/ abdominal pain and CDAI score for US, and CDAI score for ROW) at Week 52; 
clinical response (defined as a decrease from baseline in CDAI ≥ 100 points) at Week 12; 
endoscopic response-50 ([ER-50], defined as a reduction of at least 50% compared with baseline
in SES-CD) at Week 52; sustained clinical remission at both Week 12 and Week 52; steroid-free 
clinical remission at Week 52; endoscopic response-25 ([ER-25], defined as a reduction of at 
least 25% compared with baseline in SES-CD) at Week 12;
 
 
  
 
 
 
The statistical sections were revised to support the hierarchy of endpoints as listed above.

Change / Justification
Inclusion Criteria
Protocol Summary 
(Study Population);
Section 1.3.1 (Study 
Rationale and Purpose);
Section 4.2 (Inclusion 
Criteria); Section 6.5.6
(Contraception 
Education); Section 
6.6.4 Ilecolonoscopy; 
Appendix H (Definition 
of CD Treatment 
Failure and Intolerance)
Aminosalicylates were removed as one of the therapies that subjects may have failed to allow for 
study eligibility. Treatment with aminosalicylates is (a) often insufficient therapy for patients 
with CD, (b) generally not first-line therapy for patients with CD, and (c) usually prescribed in 
conjunction with other CD therapy. In addition, failed treatment with biologics was further 
specified to include infliximab, adalimumab, certolizumab or vedolizumab.   
Inclusion criteria were updated to clarify that the presence of active CD must be determined by 
ileocolonoscopy at screening (exclusive of other imaging procedures). 
Pan-colonic screening surveillance was removed as a requirement for inclusion for subjects with 
increased risk of colorectal cancer in CD, as there is no clear, global guidance with respect to
screening programs for colorectal cancer. However, Section 6.6.4 now includes a statement 
indicating that subjects with increased risk of colorectal cancer should have undergone a 
colonoscopy with pan-colonic surveillance biopsies according to local guidelines.
Clarification was added to the contraception options for inclusion, as follows:
-
The inclusion criterion requiring male subjects to use barrier contraception when engaging in 
sexual activity was removed. Based on additional PK results, there is minimal concern for
GED-0301 entering blood at such high concentrations that it could get into semen.
-
Subjects taking an oral contraceptive may need a backup or alternative method of birth 
control based on Investigator judgment. The option to change or initiate an additional birth 
control method may be implemented in cases when the Investigator suspects that the 
effectiveness of oral contraceptives may be reduced based on the severity and extent of the 
subject’s CD, which may affect gastrointestinal absorption or transit of oral contraceptives. 
These details were also added to Section 6.5.6 (Contraception Education).
Exclusion Criteria
Protocol Summary 
(Study Population), 
Section 4.3 (Exclusion 
Criteria); Section 6.6.4 
(Efficacy Assessments, 
Ileocolonoscopy);
Exclusion criteria were revised to clarify the protocol requirements with respect to strictures. 
Strictures with prestenotic dilatation, requiring procedural intervention, or with obstructive 
symptoms, will be excluded. In addition, subjects with colonic strictures not passable with an 
adult colonoscope, or strictures in the ileum or ileocecal valve that are fibrotic in nature, will be 
excluded.
Prior use of biologics is now specific to infliximab, adalimumab, certolizumab or vedolizumab.

GED-0301-CD-002 Amendment # 2 Global Final:  25 Oct 2016
Subject
Section(s) Affected
Change / Justification
Section 8.2 (Prohibited 
Concomitant 
Medications and 
Procedures); Appendix 
M (Half Lives of 
Biologics, Table 10)
These specifics were added to exclusion criteria related to prior exposure with > 3 biologics. In 
addition, an exclusion criterion was added to prohibit subjects with prior exposure to biologics 
for the treatment of CD, approved or investigational, other than infliximab, adalimumab, 
certolizumab or vedolizumab. The exclusion of subjects with  prior exposure to natalizumab was 
removed, as it is subsumed under the new exclusion criterion.
Exclusion criteria now consider the duration of 5 elimination half-lives for biologics, in addition 
to the 8 week and 1 month wash-out periods for biologics and investigational drugs, respectively. 
Appendix M (Table 10) was added to provide the half-lives for biologics, ie, infliximab, 
adalimumab, certolizumab or vedolizumab. This additional detail accounts for the variance in 
half-lives for different biologics and the need, in these cases, for a longer wash-out period. 
All bile acid sequestrants are now excluded within 3 weeks prior to screening (previously limited 
to cholestyramine). This change is reflected in the exclusion criteria and in Section 8.2 
(Prohibited Concomitant Medications and Procedures).
It is now specified that subjects with a confirmed diagnosis of colorectal dysplasia are excluded 
from the study (with the exception of adenomatous colonic polyps that have been completely 
resected), in addition to subjects with a history of colorectal cancer.
Clarification was added such that known serious infections are excluded without actively 
screening for exclusion of specific diseases (eg, tuberculosis, atypical mycobacterial disease, 
herpes zoster, or HIV). 
The amendment also includes several other minor clarifications and corrections:

Disease/ 
Compound 
Background 
Protocol Summary 
(Indication); Section 1.2 
(Compound Background)
Information was copied from the compound background section to the indication section to 
better describe the relationship between transforming growth factor – beta 1 (TGF-β1), Smads, 
and inflammatory bowel disease (IBD). Other edits were also made achieve consistency across 
the GED-0301 protocols.
Efficacy 
Measurements 
and Outcomes
Protocol Summary 
(Objectives); Section 
1.3.2 (Rationale for the 
Study Design); Table 2 
(Study Objectives); 
Appendix B (Table of 
Definitions, Table 9)
Clinical activity is now measured by average daily liquid or soft stool frequency and abdominal 
pain (as well as CDAI, as previously stated).  The definition of clinical remission now includes 
an average daily liquid or soft stool frequency ≤ 3 AND abdominal pain score ≤ 1 (or CDAI < 
150, as previously stated). Definitions for endoscopic response-25 (ER-25) and endoscopic 
response-50 (ER-50) were added. The terminology of mucosal healing was changed to 
endoscopic remission based on regulatory agency feedback.
For simplification purposes, the definitions for clinical activity and endoscopic outcomes were 
removed from the primary and secondary objectives. The Week 12 time point was added to the 
primary objective. The secondary objectives were re-ordered to coincide with the order of the 
endpoints. Time points were removed from Appendix B (Table 9) as these are no longer part of 
the definitions for efficacy outcomes. In addition, the early escape definition in Table 9 was 
updated to indicate eligibility beginning at Week 12.
 
 
 
 
SES-CD scores
Protocol Summary (Study 
Design); Section 3.1 
(Study Design); Section 
7.3 (Method of Treatment 
Assignment)
To ensure a broad distribution of Crohn’s Disease subjects, including those with more extensive 
and/or significant mucosal disease activity, the total number of subjects with a total SES-CD 
score ≥6 is targeted to comprise approximately 80% of the study population.
Options for

criteria
(Study Design); Figure 1 
(footnote); Section 7.3 
(Method of Treatment 
Assignment)
Study (GED-0301-CD-004). Subjects who meet the criteria for early escape beginning at the 
Week 12 Visit and thereafter until the Week 52 Visit, may (a) continue in the study at the 
discretion of the investigator based on the totality of clinical data, (b) enter the Long-term 
Active-treatment Study (GED-0301-CD-004), or (c) discontinue the study. 
Discontinuation

Section 3.1.2 (Early 
Termination Visit); 
Section 3.2 (End of 
Study); Table 5 (Table of 
Events); Section 6.3 
(Early Termination) 
Text was updated to indicate that subjects who discontinue at Week 12 (either because they meet 
early escape criteria or for any other reason) should complete the Week 12 Visit (instead of the 
Early Termination Visit).
Clarification was also added to emphasize that subjects who prematurely discontinue from the 
study and do not enter into the Long-term Active-treatment study will have a 4-week Follow-up 
Visit.

The figure was updated to remove the Week 2 time point and to indicate that no IP treatment is 
given during the Follow-Up period.
Contact Before 
Considering 
Subjects Lost to 
Follow up
Section 3.1.3 (Lost to 
Follow-up)
Language was revised such that the subject should be contacted through multiple (previously 3) 
telephone calls and/or emails and one registered letter before considering the subject lost to 
follow up. 
Abdominal 
examination
Table 5 (Table of Events)
footnote; Section 6.2
(Double Blind Treatment 
Period); Section 6.5.1 
(Physical examination)
Language was added to clarify that an abdominal examination will be performed at every visit
(including those visits in which a complete or limited physical exam is not being done) to assess 
the presence of an abdominal mass for the CDAI
 calculations. As a result, the statement 
regarding recording results for complete and physical examinations in source documents only 
was removed.  
Screening 
procedures
Section 6.1 (Screening 
Period); Section 6.1.1 
Additional provisions were made for screening procedures, including the ability to re-screen 
upon approval from the sponsor. In addition, for subjects who will be re-screened, endoscopies 
performed (a) as part of the original screening period, (b) within 30 days prior to the re-screen

Section(s) Affected
Change / Justification
 
 
 
 
 
Compliance with 
Investigational 
Product (IP)
Section 7.2.1 (Dose 
modification or 
interruption)
Text was revised to state that if a subject inadvertently does not take his or her medication for 4 
or more consecutive days, Celgene must be contacted to decide whether the subject may remain 
in the study.  
Overdose
Section 7.2.2 (Overdose)
The timeframe for overdose was revised to be within the same calendar day (instead of a 24 hour 
time period). Text was added to indicate that overdose also includes more than 4 tablets of 
matching placebo (in addition to GED-0301).
Concomitant 
Medications and 
Procedures
Sections 8.1 & 8.2 
(Permitted/Prohibited 
Concomitant Medications 
and Procedures)
Timeframes for discontinuation of immunosuppressants (8 weeks) and antibiotics (2 weeks) were 
added to Section 8.1. A correction was also made to the text so that no new CD therapy can be 
prescribed once the subject has been screened (instead of randomized) in the study. Text was 
added to Section 8.2 to indicate that subjects who require ileostomy, colostomy, any intestinal 
resection, or intra-abdominal surgery (related to CD) during the study, will be discontinued from 
treatment.
Analysis model
Protocol Summary 
(Statistical Methods); 
Section 9.6.1 (Statistical 
Methods)
Revisions were made to indicate that a longitudinal data analysis (LDA) model will be used to 
analyze continuous endpoints. In this model, time is treated as a categorical value so that no 
restriction is imposed on the trajectory of the means over time. In addition, the model adjusts for 
stratification factors.

GED-0301-CD-002 Amendment 1 Final: 23 Sep 2015
1.
JUSTIFICATION FOR AMENDMENT
Significant changes included in this amendment are summarized below:
Addition of Inclusion Criteria 
The primary purpose of this protocol amendment is to add inclusion criteria 
 
The rationale for this amendment is to align with 
 
  
Revised Sections: 
!
Protocol Summary, Study Population
!
Section 4.2, Inclusion Criterion # 7
!
Section 6.1.1, Screening Procedures
Update of Exclusion Criterion #12
Exclusion Criterion #12 was updated to allow stable doses of antibiotics for the treatment of 
Crohn's disease (CD), provided that the dose has been stable for at least 2 weeks prior to the 
Screening Visit. In earlier GED-0301 studies; the use of antibiotics for the treatment of CD was 
prohibited. Following discussions with clinical investigators, the use of antibiotics may be
commonly used as background therapy in subjects with CD and there is no reason to suspect a 
diminished effect of GED-0301 with its different mechanism of action. This change will support
a broader subject population to be studied in this phase 3 trial.

Revision of Exclusion Criterion #13
Exclusion Criterion #13 was revised to exclude subjects with prior treatment with 3 biologics as 
opposed to 2 biologics.
The rationale is based on the expectation of responsiveness to GED 0301 (with a different 
mechanism of action then biologic therapy) in terms of clinical and endoscopic benefit, which is 
expected to be substantively similar in patients having been exposed to either 2 or 3 biologics. 
The intention, therefore, is to study a broader group of patients with prior biologic exposure. The 
target of 65% of the subjects in this trial to be naive to prior biologic therapy is unchanged.
