baseline in total Mayo score of at least 3 points and at least 30%, with
an accompanying decrease in the rectal bleeding subscore of at least 1
point or an absolute rectal bleeding subscore of 0 or 1.
For eligibility assessment, clinical response will be determined based on
the centrally read endoscopy performed during screening and at Week
12 of induction study SHP647 301 or SHP647 302.
5. Subjects receiving any treatment(s) for UC described in Section 5.2.1
are eligible provided they have been, and are anticipated to be, on a
stable dose for the designated period of time.
Are the trial subjects under 18? yes
Number of subjects for this age range:

because of an adverse event (AE), regardless of relatedness to investigational product, in
induction study SHP647-301 or SHP647-302.
3. Subjects who are likely to require surgery for UC during the study
period.
4. Subjects are females who became pregnant during induction study
SHP647-301 or SHP647 302, females who are planning to become
pregnant during the study period, or males or females of childbearing
potential not agreeing to continue acceptable contraception methods (ie, highly effective methods for female and medically appropriate methods for male study subjects)
through the conclusion of study participation (see Section 4.4).
5. Subjects who do not agree to postpone donation of any organ or
tissue, including male subjects who are
planning to bank or donate sperm, and female subjects who are planning
to harvest or donate eggs, for the
duration of the study and through 16 weeks after last dose of
investigational product.
6. Subjects who, in the opinion of the investigator or the sponsor, will be
uncooperative or unable to comply with study procedures.
7. Subjects who have a newly diagnosed malignancy or recurrence of
malignancy (other than resected cutaneous basal cell carcinoma,
squamous cell carcinoma, or carcinoma in situ of the uterine cervix that
has been treated with no evidence of recurrence).
8. Subjects who have developed any major illness/condition or evidence
of an unstable clinical condition (eg, renal, hepatic, hematologic,
gastrointestinal (except disease under study), endocrine, cardiovascular,
pulmonary, immunologic [eg, Felty's syndrome], or local active
infection/infectious illness) that, in the investigator's judgment, will substantially increase the risk to the subject if he or she participates in
the study.
9. Subjects with any other severe acute or chronic medical or psychiatric
condition or laboratory or ECG abnormality that may increase the risk
associated with study participation or investigational product
administration or may interfere with the interpretation of study results
and, in the judgment of the investigator, would make the subject
inappropriate for entry into this study.
10. Subjects with known exposure to Mycobacterium tuberculosis (TB)
since testing at screening in induction study SHP647-301 or SHP647-302
and who are without a generally accepted course of treatment.
11. Subjects who are investigational site staff members or relatives of
those site staff members or subjects who are sponsor employees directly
involved in the conduct of the study.
12. Subjects who are participating in or plan to participate in other
investigational studies (other than induction study SHP647-301 or
SHP647 302) during study SHP647-303.

Primary Outcome(s)
Secondary Objective: The key secondary objectives of the study are as follows:
¿ To evaluate the efficacy of ontamalimab on endoscopic remission, based on centrally read endoscopy.
¿ To evaluate the efficacy of ontamalimab on clinical remission, based on composite score of patient-reported symptoms.
¿ To evaluate the efficacy of ontamalimab on maintenance of remission among subjects in remission at baseline of the SHP647-303 study, based on composite score of patient-reported symptoms and centrally read endoscopy.
¿ To evaluate the efficacy of ontamalimab on clinical response, based on composite score of patient-reported symptoms and centrally read endoscopy.

¿ To evaluate the efficacy of ontamalimab on glucocorticoid free remission.
Main Objective: The primary objective of the study is to evaluate the efficacy of ontamalimab
as maintenance treatment of remission, based on composite score of
patient reported symptoms and centrally read endoscopy, in subjects
with moderate to severe UC.
Primary end point(s): The primary efficacy endpoint is proportion of subjects in remission at
the Week 52 visit. Remission is defined as a composite score of patientreported
symptoms using daily e-diary and centrally read endoscopy as
follows:

stool frequency subscore of 0 or 1 with at least a 1-point change from
induction
(SHP647 301 or SHP647 302) baseline
AND

rectal bleeding subscore of 0
AND

endoscopic subscore of 0 or 1 (modified, excludes friability).
Timepoint(s) of evaluation of this end point: Week 52 visit
Secondary Outcome(s)
Timepoint(s) of evaluation of this end point: week 52 visit; week 52 visit; week 52 visit; week 52 visit; week 52 visit; week 52 visit; week 52 visit
Secondary end point(s): ¿ Proportion of subjects with endoscopic remission, as defined by
centrally read endoscopic subscore 0 or 1 (modified, excludes friability),
at the Week 52 visit.
; Proportion of subjects with clinical remission as defined by stool
frequency subscore of 0 or 1 with at least a 1-point change from
induction study (SHP647-301 or SHP647-302) baseline in stool
frequency subscore, and rectal bleeding subscore of 0, at the Week 52
visit.
; Proportion of subjects with sustained remission, ie, in remission at the
SHP647-303 Week 52 visit, among subjects who were in remission at the
time of baseline in study SHP647 303. Remission is defined as a
composite score of patient-reported symptoms using daily e-diary and
centrally read endoscopy, with stool frequency subscore of 0 or 1 with at
least a 1-point change from induction study (SHP647-301 or SHP647302)
baseline, and rectal bleeding subscore of 0, and endoscopic
subscore
of 0 or 1 (modified, excludes friability).
; Proportion of subjects with clinical response based on composite score
at the Week 52 visit. Clinical response (composite) is defined as a
decrease from induction study (SHP647-301 or SHP647 302) baseline in
the composite score of subject-reported symptoms using daily e diary
and centrally read endoscopy of at least 2 points and at least 30%, with
an accompanying decrease in the subscore for rectal bleeding =1 point
or a subscore for rectal bleeding =1. ; Proportion of subjects with mucosal healing, based on endoscopic and
histologic assessment, at the Week 52 visit. Mucosal healing is defined
by centrally read endoscopic subscore 0 or 1 (modified, excludes
friability) and centrally read Geboes score of =2.

remission in addition to not requiring any treatment with glucocorticoids
for at least 4 weeks prior to the Week 52 visit. Clinical remission is
defined as stool frequency subscore of 0 or 1 with at least a 1-point

52, among subjects using glucocorticoids in study SHP647-303 baseline.
Glucocorticoid-free remission is defined as remission in addition to not
requiring any treatment with glucocorticoids for at least 4 weeks prior to
the Week 52 visit. Remission is defined as a composite score of subjectreported
symptoms using daily e diary and endoscopy, with stool
frequency
subscore of 0 or 1 with at least a 1-point change from
