Background summary
Crohn*s disease (CD) is a chronic, relapsing disease marked by granulomatous
inflammation of the gastrointestinal (GI) tract. Although the terminal ileum
and right colon are the most commonly involved sites, CD can affect any part of
the GI tract, from the mouth to the perianal region. Inflammation is typically
transmural (full-thickness), segmental, and discontinuous, and symptoms are
predominantly determined by the part of bowel or organ involved. Patients
typically present with symptoms including abdominal pain, diarrhea, rectal
bleeding, which may be persistent and lead to anemia, and weight loss due to
pain on eating and malabsorption. As the disease progresses, extraintestinal
manifestations and associated conditions can develop, including bowel
obstruction, fistulas, and stenosis, as well as painful skin ulcerations, eye
pain, and arthritis.
No clear difference in incidence has been observed between men and women.
Although CD can occur at any age, peak incidence has been observed in the
second to fourth decades of life, with a second modest rise in incidence in the
latter decades of life (Molodecky et al., 2012).
Crohn*s disease is a lifelong condition with a serious effect on quality of
life. The traditional approach to therapy of CD has been the step-up approach
usually represented as a pyramid where, progressing from mild to severe
disease, therapeutic choices proceed step by step from less potent drugs at the
base of the pyramid to more potent but also more toxic drugs at the top.
Despite recent advances, there is still an unmet need for a safe, effective,
and durable pharmacological treatment that will induce and maintain clinical
remission.
The selectivity of lymphocyte homing to specialized lymphoid tissue and mucosal
sites of the GI tract is influenced by the endothelial expression of mucosal
addressin cell adhesion molecule (MAdCAM). MAdCAM plays a role in gut immune
surveillance, and also appears to facilitate excessive lymphocyte infiltration
under conditions of chronic GI inflammation.
Ontamalimab is a fully human immunoglobulin G2 kappa (IgG2k) monoclonal
antibody that binds to human MAdCAM to reduce lymphocyte homing to the gut and
GI inflammation.

Study design
The study consists of a screening period up to 6 weeks and a 16 week treatment
period. After the screening period, eligible subjects will be randomized to
receive 1 of 3 treatments (25 mg ontamalimab, 75 mg ontamalimab, or placebo) in
a 3:3:2 ratio. Randomization will be stratified based upon the subject*s status
of prior antitumor necrosis factor (TNF) treatment (naïve or experienced),
glucocorticoid use at baseline (on glucocorticoids at baseline versus not on
glucocorticoids at baseline), and Simple Endoscopic Score for CD (SES-CD) at
baseline (SES-CD *17 or SES CD <17). Subjects will receive SC injections of
SHP647 or placebo, using a PFS, on Week 0/Day 1 (Visit 2), Week 4 (Visit 4),
Week 8 (Visit 5), and Week 12 (Visit 6). Subjects will undergo efficacy,
biomarker, pharmacokinetic (PK), safety, and health outcome assessments at
these visits.
At the end of the 16 week treatment period, subjects will be offered the
opportunity to participate in either a double blind maintenance study
(SHP647-307; for subjects who fulfill the entry criteria) or a long-term safety
extension (LTS) study (SHP647-304; for subjects who do not fulfill the entry
criteria for Study SHP647 307). Subjects who withdraw early from the 16 week
treatment period or who do not wish to enter the maintenance study (SHP647-307)
or LTS study (SHP647-304) will continue into a 16 week safety follow-up period.
Only those subjects who complete the full course of investigational product
treatment in the induction study (SHP647 305) will be eligible to continue in
the maintenance study or LTS study.
Intervention
The participants receive a subcutaneous injection every 4 weeks; 1 group with
25 mg ontamalimab, 1 group with 75 mg ontamalimab, and 1 group with placebo.
Study burden and risks
Ontamalimab may cause side effects. The most frequently reported side effects
(in more than 1 out of every 10 subjects who received ontamalimab) across all
studies and from any cause, including possibly ontamalimab, were joint pain,
headache, pain in the belly, nausea, fever and inflammation or infection of the
nasal passages and the throat. These side effects were generally mild to
moderate.
Side effects reported less frequently (in more than 1 out of every 20 subjects
but less than 1 out of every 10 subjects who received ontamalimab) across all
studies and from any cause, including possibly ontamalimab, were vomiting,
fatigue, back pain, diarrhea, influenza (the flu), urinary tract infections,
inflammation or infection of the gastrointestinal tract, upper respiratory
infection, inflammation of the bronchial tubes that carry air to the lungs,
bodily rash, inflammation or infection of the throat, and anemia (reduced red
blood cells). These side effects were also generally mild to moderate.Also the
study procedures may be accompanied by risks and discomforts. In addition the
study drug, the study procedures and the combination of these may lead to risks
that are as yet unknown.
Crohn*s disease (CD) is a chronic, relapsing disease marked by granulomatous
inflammation of the gastrointestinal (GI) tract. CD is a lifelong condition
with a serious effect on the quality of life. Current treatment primarily
consists of symptomatic management. Despite recent advances, there is still an
unmet need for an effective pharmacological treatment that will induce and
maintain remission. Considering the chronic and relapsing characteristics of
this lifelong disease, we feel these side effects and the burden associated
with participation, are in proportion considering the positive effects that
participation in the study might have on the patients disease.

performed up to 12 weeks before study entry [screening, Visit 1] may be used if
available; documentation of the official reading must be located and available
in the source documentation.)
24. Subjects with evidence of active or latent infection with Mycobacterium
tuberculosis (TB) or subjects with this history who have not completed a
generally accepted full course of treatment before baseline (Visit 2) are
excluded. All other subjects must have either the Mantoux (purified protein
derivative [PPD]) tuberculin skin test or interferon-gamma release assay (IGRA)
performed.
Subjects who have no history of previously diagnosed active or latent

test (ie *5 mm induration) or a positive IGRA (the latter to be tested at the
site*s local laboratory) during screening or within 12 weeks before screening.
If the IGRA cannot be performed locally, a central laboratory may be used, with
prior agreement from the sponsor.
* An IGRA is strongly recommended for subjects with a prior bacillus Calmette
Guérin vaccination, but may be used for any subject. Documentation of IGRA
product used and the test result must be in the subject's source documentation
if performed locally. Acceptable IGRA products include QuantiFERON-TB Gold Plus
In-Tube Test.
* If the results of the IGRA are indeterminate, the test may be repeated, and
if a negative result is obtained, enrollment may proceed. In subjects with no
history of treated active or latent TB, a positive test on repeat will exclude
the subject. Subjects with a history of active or latent TBinfection must
follow instructions for *Subjects with a prior diagnosis of active or latent TB
are excluded unless both of the following criteria are met* in this criterion.
* Subjects with repeat indeterminate IGRA results, with no prior TB history,
may be enrolled after consultation with a pulmonary or infectious disease
specialist who determines low risk of infection (ie, subject would be
acceptable for immunosuppressant [eg, anti-TNF] treatment without additional
action). This consultation must be included in source documentation.
Results from a chest x-ray, taken within the 12 weeks before or during
screening (Visit 1) must show no abnormalities suggestive of active TB
infection as determined by a qualified medical specialist.

either latent (eg, 9 months of isoniazid or an acceptable alternative regimen,
in a locale where rates of primary multidrug TB resistance are <5%. Subjects
from regions with higher rates of primary multidrug TB resistance are excluded)
or active (acceptable multidrug regimen) TB infection. Evidence of diagnosis
and treatment must be included in source documentation. Consultation with a
pulmonary or infectious disease specialist to confirm adequate treatment (ie,
subject would be acceptable for immunosuppressant [eg, anti TNF] treatment
without additional action) must be performed during the screening period. The
consultation report must be included in source documentation prior to
enrollment.
