Primary Outcome Measures :
  1. Number of Participants With Treatment Emergent Adverse Events (TEAEs) [ Time Frame: Baseline up to 16 weeks post end of treatment (EOT) [up to 7 years] ]
    An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Treatment-emergent AEs (TEAEs) are defined as AEs with start dates or worsening dates at the time of or following the first exposure to investigational product. The TEAEs will be further categorized based on severity as mild (may require only minimal treatment) to severe (may require intensive therapeutic intervention).

  2. Number of Participants With Serious Infections [ Time Frame: Baseline up to 16 weeks post EOT (up to 7 years) ]
    Number of participants with serious infections will be assessed.

  3. Number of Participants With Clinically Significant Change in Clinical Laboratory Tests Reported as an Adverse Event [ Time Frame: Baseline up to 16 weeks post EOT (up to 7 years) ]
    Clinical laboratory assessments include hematology, serum chemistry and urinalysis. Any clinically significant change in the clinical laboratory value from baseline will be recorded as an AE.

  4. Number of Participants With Clinically Significant Change in Electrocardiogram (ECG) Reported as an Adverse Event [ Time Frame: Baseline up to EOT (up to 7 years) ]
    12-lead ECG will be recorded. Any clinically significant change in ECG will be recorded as an AE.

  5. Number of Participants With Clinically Significant Change in Vital Signs Reported as an Adverse Event [ Time Frame: Baseline up to 16 weeks post EOT (up to 7 years) ]
    Vital sign assessments include blood pressure, pulse, respiratory rate and temperature. Any clinically significant change in vital signs from baseline will be recorded as an AE.

  6. Number of Participants who Developed Antidrug Antibodies to SHP647 [ Time Frame: Baseline up to EOT (up to 7 years) ]
    Number of participants with presence of antidrug antibodies to SHP647 will be assessed.


Secondary Outcome Measures :
  1. Number of Participants With Ulcerative Colitis With Remission Based on Composite Score [ Time Frame: Yearly once till EOT (up to 7 years) ]
    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 baseline and rectal bleeding subscore of 0 and locally-read endoscopic subscore of 0 or 1 (modified, excludes friability). The stool frequency subscore, rectal bleeding subscore and endoscopic subscore of mayo score ranges from 0 to 3 with higher scores indicating more severe disease. The Mayo score is a measure of UC disease activity. It ranges from 0 to 12 points and consists of 4 subscores, each graded from 0 to 3 with higher scores indicating more severe disease. The subscores are Stool frequency (0-3); Rectal bleeding (0-3); Findings of endoscopy (0-3); Physician global assessment (PGA, 0-3). The composite score is a recommended measure consisting of the Mayo score without the PGA subscore and ranges from 0 to 9 points.

  2. Number of Participants With Ulcerative Colitis With Remission Based on Total Mayo Score [ Time Frame: Yearly once till EOT (up to 7 years) ]
    Remission is defined as a total mayo score less than or equal to (<=) 2 with no individual subscore (stool frequency, rectal bleeding, endoscopy [modified, excludes friability], and physician's global assessment) exceeding 1. The total mayo score ranges from 0 to 12 points and consists of the following 4 subscores, each graded from 0 to 3 with higher scores indicating more severe disease: bowel movement frequency (0-3); rectal bleeding (0-3); findings of flexible sigmoidoscopy or endoscopy (0-3); physician global assessment (PGA; 0-3).

  3. Number of Participants With Ulcerative Colitis With Clinical Remission [ Time Frame: Yearly once till EOT (up to 7 years) ]
    Clinical remission as defined by stool frequency subscore of 0 or 1 with at least a 1-point change from induction study baseline in stool frequency subscore, and rectal bleeding subscore of 0. The stool frequency subscore and rectal bleeding subscore of mayo score ranges from 0 to 3 with higher scores indicating more severe disease. The Mayo score is a measure of UC disease activity. It ranges from 0 to 12 points and consists of 4 subscores, each graded from 0 to 3 with higher scores indicating more severe disease. The subscores are Stool frequency (0-3); Rectal bleeding (0-3); Findings of endoscopy (0-3); Physician global assessment (PGA, 0-3).

  4. Number of Participants With Ulcerative Colitis With Partial Mayo Score Over Time [ Time Frame: Baseline up to EOT(up to 7 years) ]

The subscores are Stool frequency (0-3); Rectal bleeding (0-3); Findings of endoscopy (0-3); Physician global assessment (PGA, 0-3).

  6. Number of Participants With Crohn's Disease With Clinical Remission Over Time as Measured by 2-Item Patient Reported Outcome [ Time Frame: Baseline up to EOT(up to 7 years) ]
    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 [0=no pain to 10= worst imaginable pain]) and average daily stool frequency of <=2 of type 6/7 (very soft stools/liquid stools) over the 7 most recent days. Stool consistency will be assessed by typical stool form based on Bristol Stool Form Scale: 1 - Separate hard lumps, hard to pass, 2 - Sausage-shaped, but lumpy, 3 - Like a sausage but with cracks on the surface, 4 - Like a sausage or snake, smooth and soft, 5 - Soft blobs with clear-cut edges, 6 - Fluffy pieces with ragged edges, a mushy stool, 7 - Watery, no solid pieces, entirely liquid.

  7. Number of Participants With Crohn's Disease With Enhanced Endoscopic Response [ Time Frame: Yearly once till EOT (up to 7 years) ]
    Enhanced endoscopic response is measured as a decrease in simple endoscopic activity score for crohn's disease (SES-CD) of at least 50 percent (%) from induction study baseline. The SES-CD is a simple scoring system based on 4 endoscopic variables measured in the same 5 ileocolonic segments as the Crohn's disease index of severity. Overall, values on the SES-CD range from 0-56, with higher values indicating more severe disease. The 4 endoscopic variables are scored from 0-3 in each bowel segment (ileum, right/transverse/left colon, and rectum): Presence and size of ulcers (none = score 0; diameter 0.1-0.5 centimetre (cm) = score 1; 0.5-2 cm = score 2; diameter more than (>)2 cm = score 3); extent of ulcerated surface (none = 0; less than (<)10 % =1; 10%-30% = 2; >30% = 3); extent of affected surface (none = 0; <50% = 1; 50%-75% = 2; >75% = 3); Presence and type of narrowings (none = 0; single, can be passed = 1; multiple, can be passed = 2; cannot be passed = 3).

  8. Number of Participants With Crohn's Disease With Clinical Remission Over Time as Measured by Crohn's Disease Activity Index (CDAI) Less Than (<)150 [ Time Frame: Baseline up to EOT (up to 7 years) ]
    The CDAI is a composite measure with 8 components; 3 components (abdominal pain severity, very soft stool/liquid stool frequency, and general wellbeing) will be self-reported by the participant and will be recorded as part of the daily e-diary and 5 components (weight, medical and physical examination, use of diarrhea treatment, and hematocrit value) will be collected at clinical visit. The CADI score scale ranges from 0 to > 451. 0-149 points: Asymptomatic remission; 150-220 points: Mild to moderate active Crohn's Disease (CD); 221-450 points: Moderate to severe active CD; >451 points: Severely active to fulminant disease.

  9. Number of Participants With Crohn's Disease With Clinical Remission Over Time [ Time Frame: Baseline up to EOT(up to 7 years) ]
    Clinical remission over time is defined as CD daily e-diary subscores of average worst daily abdominal pain <=1 (based on the 4-point scale) and average daily stool frequency <=3 of type 6/7 (very soft stools/liquid stools) as per BSFS over the 7 most recent days.

  10. Number of Participants With Crohn's Disease With Clinical Remission and Enhanced Endoscopic Response Over Time [ Time Frame: Baseline up to EOT (up to 7 years) ]
    Clinical remission over time is defined as CD daily e-diary subscores of average worst daily abdominal pain <=1 (based on the 4-point scale) and average daily stool frequency <=3 of type 6/7 (very soft stools/liquid stools) as per BSFS over the 7 most recent days. Enhanced endoscopic response is measured as a decrease in simple endoscopic activity score for crohn's disease (SES-CD- ranging from 0 to 56, with higher values indicating more severe disease) of at least 50% from induction study baseline.

  11. Number of Participants With Crohn's Disease With Complete Endoscopic Healing [ Time Frame: EOT (Approximately 7 years) ]
    Complete endoscopic healing is defined as SES-CD = 0-2. The SES-CD is a simple scoring system based on 4 endoscopic variables measured in the same 5 ileocolonic segments as the Crohn's disease index of severity. Overall, values on the SES-CD range from 0-56, with higher values indicating more severe disease. The 4 endoscopic variables are scored from 0-3 in each bowel segment (ileum, right/transverse/left colon, and rectum): Presence and size of ulcers (none = score 0; diameter 0.1-0.5 centimetre (cm) = score 1; 0.5-2 cm = score 2; diameter more than (>)2 cm = score 3); extent of ulcerated surface (none = 0; less than (<)10 % =1; 10%-30% = 2; >30% = 3); extent of affected surface (none = 0; <50% = 1; 50%-75% = 2; >75% = 3); Presence and type of narrowings (none = 0; single, can be passed = 1; multiple, can be passed = 2; cannot be passed = 3).
