- Participants are females who became pregnant during study SHP647-305, SHP647-306 or SHP647-307, females who are lactating, females who are planning to become pregnant during the study period, or males or females of childbearing potential not agreeing to continue appropriate contraception methods (i.e. highly effective methods for female and medically appropriate methods for male study participants) through the conclusion of study participation.

- Primary Outcome Measures
Name Time Method Number of Participants With Treatment Emergent Adverse Events (TEAEs) From first dose of study drug up to end of study [EOS] (up to 5.79 years) An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Treatment-emergent AEs (TEAEs) were defined as AEs with start dates or worsening dates at the time of or following the first exposure to investigational product.
Number of Participants With Discernible Changes in Vital Signs Over Time From first dose of study drug up to EOS (up to 5.79 years) Vital sign assessments included blood pressure, pulse, respiratory rate, and temperature. Any discernible changes in vital signs over time per investigator interpretation were reported.
Number of Participants With Serious Infections From first dose of study drug up to EOS (up to 5.79 years) Serious infections were defined as any infections that were life-threatening or those requiring hospitalization or intravenous antibiotics based on the investigator's assessment.
Number of Participants With Notable Changes in Clinical Laboratory Parameters Over Time From first dose of study drug up to EOS (up to 5.79 years) Clinical laboratory assessments included hematology, serum chemistry and urinalysis. Any notable changes in the clinical laboratory value over time based on the investigator interpretation were reported.
Number of Participants With Discernible Changes in Electrocardiogram (ECG) Over Time From first dose of study drug up to EOS (up to 5.79 years) ECG included heart rhythm, heart rate, QRS intervals, QT intervals, RR intervals and corrected QT (QTc) intervals parameters measurement. Any discernible changes in the ECG value over time based on investigator interpretation were reported.
- Secondary Outcome Measures
Name Time Method Number of Participants With Ulcerative Colitis With Treatment Response Over Time Up to 5.79 years Treatment response over time was defined as clinical composite score that has decreased by greater than or equal to (≥2) points and ≥30 percentage (%), with an accompanying decrease in the sub score for rectal bleeding (RB) ≥1 point or a subscore for RB ≤ 1, and/or composite score that has decreased by ≥30% and ≥3 points compared to the baseline value for induction studies. The clinical composite score is a measure consisting of sub scores RB (0-3) plus stool frequency (0-3) with higher scores indicating more severe disease. With the implementation of amendment 4 of the protocol the study became a single arm study with all participants receiving the 75 mg dose of ontamalimab. Hence, only those UC participants who were receiving the 75 mg dose of ontamalimab every 4 weeks and participating in amendment 4 of the protocol were analyzed in this outcome measure.
Number of Participants With Crohn's Disease With Treatment Response Over Time Up to 5.79 years Treatment response over time=Crohn's Disease Activity Index(CDAI)score that has decreased ≥100 points and/or simple endoscopic score for Crohn's disease(SES-CD)that has decreased by ≥25%,both compared to baseline value for induction studies.SES-CD is simple scoring system with 4 endoscopic variables measured in same 5 ileocolonic segments as CD index of severity. Overall values on SES-CD range from 0-56,higher values=more severe disease.4 endoscopic variables are scored from 0-3 in each bowel segment:ileum,right/transverse/left colon,rectum. Presence \& size of ulcers(none=0;diameter 0.1-0.5centimeter(cm)=1;0.5-2cm=2;\>2cm=3);extent of ulcerated surface(none=0;\<10%=1;10%-30%=2; \>30%= 3);extent of affected surface(none=0;\<50%=1;50%-75%=2;\>75%=3);Presence \& type of narrowing (none=0;single can be passed=1;multiple can be passed=2;cannot be passed=3).
