Key inclusion & exclusion criteria
Inclusion criteria:
Subjects with UC Entering from an Induction or Maintenance Study:
1. Subjects must have been previously enrolled in study SHP647-301, SHP647 302, or SHP647-303, and reached 1 of the following clinical trial milestones:
- Completed the Week 12 visit in induction study SHP647-301 or SHP647 302, and did NOT achieve a clinical response. Clinical response is defined as: 1) a decrease from baseline in the composite score of
patient-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, OR 2) a decrease from the induction study (SHP647-301 or SHP647-302) baseline 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.
- Completed the Week 52 visit in maintenance study SHP647-303.
- Withdrew early from maintenance study SHP647-303 due to treatment failure, defined by an endoscopic subscore that has increased by at least 1 point over baseline in the maintenance study or a value =2 plus an increase in clinical subscore (stool frequency + rectal bleeding score) of
at least 2 points. Centrally read endoscopic subscores will be used to determine treatment failure.
2. 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.

8. Subjects who have developed any major illness/condition or evidence of an unstable clinical condition (except disease under study) 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 electrocardiogram (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 ?.tuberculosis (TB) since testing at screening in previous UC/CD studies and who have been advised to require treatment for latent or active disease, but who are without agenerally accepted course of treatment.

3. Subjects with past medical history or presence of toxic megacolon.
4. Subjects with colonic stricture, past medical history of colonic resection, a history of bowel surgery within 6 months before screening, or who are likely to require surgery for UC during the treatment period.
5. Subjects at risk for colorectal cancer must have a colonoscopy (Eaden and Mayberry, 2002) performed during the screening period with results available within 10 days before the baseline visit (Visit 1), unless the subject has had a surveillance colonoscopy performed within 1 year prior to screening, and any adenomatous polyps found at that examination have been excised. 6. Subjects with known or suspected intolerance or hypersensitivity to the investigational product(s), closely related compounds, or any of the stated ingredients.
7. Subjects have received anti-TNF treatment within 60 day

Primary Outcome(s)
Main Objective: The primary objective of the study is to evaluate the safety and tolerability of long-term treatment with ontamalimab in subjects with moderate to severe ulcerative colitis (UC) or Crohn's disease (CD).
Primary end point(s): The primary endpoint is safety assessment as is assessment of safety as measured by: incidence and severity of AEs; incidence and nature of serious infections; actual values and change from baseline, as well as the incidence of abnormalities, in laboratory tests, ECGs, and vital signs; and antidrug antibodies.
Timepoint(s) of evaluation of this end point: Please refer to section “Study Schedules” of the Protocol
Secondary Objective: Secondary - Subjects with Ulcerative Colitis:
? To evaluate the effect of long-term ontamalimab treatment on clinical outcomes (including remission over time based on composite score of patient-reported symptoms using daily
diary and locally read endoscopy, Mayo-based remission over time, clinical remission over time, partial
Mayo score over time).
? To evaluate the effect of long-term ontamalimab treatment on endpoints related to endoscopic healing.

Secondary - Subjects with Crohn's Disease:
? To evaluate the effect of long-term ontamalimab treatment on clinical outcomes (including 2 -item patient-reported outcome [PRO ]-based clinical response over time, 2 item PRO-based and Crohn's Disease
Activity Index [CDAI]-based clinical remission over time)
? To evaluate the effect of long-term ontamalimab treatment on endpoints related to endoscopic
outcomes
(enhanced endoscopic response as well as endoscopic healing).
Secondary Outcome(s)
Secondary end point(s): Secondary Efficacy Endpoints – Subjects with Ulcerative Colitis:
The secondary efficacy endpoints are as follows:
• Remission based on composite score, assessed yearly and at end of study. Remission is defined as a composite score of patient-reported symptoms using daily diary and locally read endoscopy as follows: stool frequency subscore of 0 or 1 with at least a 1-point change from induction study (SHP647-301 or SHP647-302) baseline, or study SHP647-304 baseline for direct-entry subjects, AND rectal bleeding subscore of 0 AND locally-read endoscopic subscore of 0 or 1 (modified, excludes friability).
• Remission, based on total Mayo score, assessed yearly and at end of study. Remission is defined as a total Mayo score = 2 with no individual subscore (stool frequency, rectal bleeding, endoscopy [modified, excludes friability], and physician's global assessment) exceeding 1.
• 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, or study SHP647-304 baseline for direct-entry subjects, in stool frequency subscore, and rectal bleeding subscore of 0, assessed yearly and at end of study.
• Partial Mayo score of =2 with no individual subscore >1 over time. The partial Mayo score does not include the endoscopy subscore.
• Endoscopic remission, as defined by locally read endoscopic subscore 0 or 1 (modified, excludes friability), assessed yearly and at end of study.

Secondary Efficacy Endpoints – Subjects with Crohn's Disease:
The secondary efficacy endpoints are as follows:
• Clinical remission over time. Clinical remission is defined by 2-item PRO CD daily e-diary subscore of average worst daily abdominal pain =3 (based on 11-point numeric rating scale [NRS] over the 7 most recent days) and average daily stool frequency =2 of type 6/7 (very soft stools/liquid stools) as shown in the BSFS over the 7 most recent days.
• Enhanced endoscopic response, assessed yearly and at end of study, as measured by a decrease in Simple Endoscopic Score for Crohn's Disease [SES-CD) of at least 50% from induction study (SHP647-305 or SHP647-306) baseline.
• Clinical remission over time as measured by CDAI <150.
• Clinical remission over time as defined by the following: CD daily e diary subscores of average worst daily abdominal pain =1 (based on the 4-point scale) over the 7 most recent days and average daily stool frequency =3 of type 6/7 (very soft stools/liquid stools) as shown in the BSFS over the 7 most recent days.
• Both clinical remission by 2-item PRO and enhanced endoscopic response over time (composite endpoint).
• Complete endoscopic healing at end of study, defined as SES-CD=0-2.
All efficacy analyses will be performed using the full-analysis set.
Secondary efficacy endpoints will be summarized by treatment group using descriptive statistics at each assessment visit. Summaries may be presented by the status at entry into the study (eg, induction non responder, maintenance ontamalimab completer, etc). Statistical summaries will include number of subjects and percentages, and 95% confidence
intervals.
Timepoint(s) of evaluation of this end point: assessed every 24 weeks, yearly, at end of study, or a combination, as detailed in E.5.1
