    Outcome Measures

    Primary Outcome Measures

    1. Proportion of participants who are in clinical remission at Week 24 [Week 24]

      Clinical remission by modified Mayo score is defined as a modified Mayo score of ≤2 with a stool frequency score ≤1, a rectal bleeding score = 0, AND a Mayo endoscopic subscore ≤1 with absence of friability. The modified Mayo score consists of 3 subscores; a patient-reported subscore for rectal bleeding, a patient-reported subscore for stool frequency, and a Mayo endoscopic subscore. Each subscore ranges 0-3 with higher scores indicating greater disease severity. The total modified Mayo score ranges 0-9 with higher scores indicating greater disease severity.

    Secondary Outcome Measures

    1. Proportion of participants achieving clinical response by modified Mayo score at Week 8, Week 24, and Week 52 [Week 8, Week 24 and Week 52]

      Clinical response by modified Mayo score is defined as a decrease from baseline in the modified Mayo score of ≥2 points and at least a 30% reduction from baseline, and a decrease in rectal bleeding subscore of ≥1 OR an absolute rectal bleeding subscore of 0 or 1. The modified Mayo score consists of 3 subscores; a patient-reported subscore for rectal bleeding, a patient-reported subscore for stool frequency, and a Mayo endoscopic subscore. Each subscore ranges 0-3 with higher scores indicating greater disease severity. The total modified Mayo score ranges 0-9 with higher scores indicating greater disease severity.

    2. Proportion of participants who are in clinical remission by modified Mayo score at Week 8 and Week 52 [Week 8 and Week 52]

      Clinical remission by modified Mayo score is defined as a modified Mayo score of ≤2 with a stool frequency score ≤1, a rectal bleeding score = 0, AND a Mayo endoscopic subscore ≤1 with absence of friability. The modified Mayo score consists of 3 subscores; a patient-reported subscore for rectal bleeding, a patient-reported subscore for stool frequency, and a Mayo endoscopic subscore. Each subscore ranges 0-3 with higher scores indicating greater disease severity. The total modified Mayo score ranges 0-9 with higher scores indicating greater disease severity.

    3. Proportion of participants in symptomatic remission over time [Baseline up to Week 52]

      Symptomatic remission is defined as Mayo stool frequency score = 0, or Mayo stool frequency score = 1 with a ≥1-point decrease from baseline, and Mayo rectal bleeding score = 0.

    4. Proportion of participants achieving histologic-endoscopic healing at Week 8, Week 24, and Week 52 [Week 8, Week 24 and Week 52]

      Histologic-endoscopic healing is defined by Mayo endoscopic subscore of 0 or 1 and histological healing (Geboes score <2). Mayo endoscopic subscore ranges 0-3 with higher scores indicating greater disease severity. The Geboes Index score is a six-grade classification system for inflammation: Grade 0 - structural change only; Grade 1 -chronic inflammation; Grade 2 - lamina propria neutrophils; Grade 3 - neutrophils in epithelium; Grade 4 - crypt destruction; and Grade 5 - erosions or ulcers.

    5. Proportion of participants with a Mayo endoscopic subscore of 0 or 1 without friability at Week 8, Week 24, and Week 52 [Week 8, Week 24 and Week 52]

      The Mayo endoscopic subscore ranges 0-3 with higher scores indicating greater disease severity.

    6. Proportion of participants with a Mayo endoscopic subscore of 0 at Week 8, Week 24, and Week 52 [Week 8, Week 24 and Week 52]

      The Mayo endoscopic subscore ranges 0-3 with higher scores indicating greater disease severity.

    7. Change from baseline in the partial Mayo score at Week 8, Week 24, and Week 52 [Baseline to Week 8, Week 24 and Week 52]

      The partial Mayo score consists of 3 subscores; a patient-reported subscore for rectal bleeding, a patient-reported subscore for stool frequency, and a Physician's global assessment (PGA) subscore. Each subscore ranges 0-3 with higher scores indicating greater disease severity. The partial Mayo score ranges 0-9 with higher scores indicating greater disease severity.

    8. Proportion of participants in clinical remission at Week 52 who are off concomitant oral corticosteroids (OCS) at least 4 weeks prior to Week 52 [Baseline up to Week 52]

      Clinical remission by modified Mayo score is defined as a modified Mayo score of ≤2 with a stool frequency score ≤1, a rectal bleeding score = 0, AND a Mayo endoscopic subscore ≤1 with absence of friability. The modified Mayo score consists of 3 subscores; a patient-reported subscore for rectal bleeding, a patient-reported subscore for stool frequency, and a Mayo endoscopic subscore. Each subscore ranges 0-3 with higher scores indicating greater disease severity. The total modified Mayo score ranges 0-9 with higher scores indicating greater disease severity.

    9. Proportion of participants in clinical remission at Week 52 who are off concomitant oral corticosteroids (OCS) at least 4 weeks prior to Week 52 among participants receiving OCS at baseline [Baseline up to Week 52]

      Clinical remission by modified Mayo score is defined as a modified Mayo score of ≤2 with a stool frequency score ≤1, a rectal bleeding score = 0, AND a Mayo endoscopic subscore ≤1 with absence of friability. The modified Mayo score consists of 3 subscores; a patient-reported subscore for rectal bleeding, a patient-reported subscore for stool frequency, and a Mayo endoscopic subscore. Each subscore ranges 0-3 with higher scores indicating greater disease severity. The total modified Mayo score ranges 0-9 with higher scores indicating greater disease severity.

    10. Change from baseline in abdominal pain assessed by Abdominal Pain Numerical Rating Scale (NRS) at Week 8, Week 24, and Week 52 [Baseline to Week 8, Week 24 and Week 52]

      Abdominal pain NRS is a single item patient report outcome (PRO) tool that patients will use to report intensity of their worst abdominal pain during a daily recall period with 0 being 'no pain' and 10 being the 'worst pain imaginable'.

    11. Incidence of treatment-emergent adverse events (TEAEs) or serious adverse events (SAEs) [Baseline up to Week 64]

    12. Concentration of dupilumab in serum over time. [Baseline up to Week 52]

    13. Incidence of treatment-emergent antidrug antibodies (ADA) against dupilumab. [Baseline up to Week 64]

    14. Change from baseline (Screening visit) in the normalized enrichment scores (NES) in type 2 inflammation transcriptome signature at Week 24 and Week 52. [Baseline to Week 24 and Week 52]

      NES is a summary score of the expression of a specified set of genes defining a molecular phenotype.

    Exclusion Criteria:
    Participants are excluded from the study if any of the following criteria apply:
    • Severe extensive colitis as evidenced by:

    • Current hospitalization

    • Likely to require surgery for the treatment of UC within 12 weeks of Screening Visit

    • UC limited to the rectum only or to <20 cm of the colon.

    • Presence of an ileal pouch, ostomy, stoma or fistula or history of a fistula.

    • Require, or required within the 2 months before screening, surgery for active gastrointestinal bleeding, peritonitis, intestinal obstruction, or intra-abdominal or pancreatic abscess requiring surgical drainage, or other conditions possibly confounding the evaluation of benefit from study agent treatment.

    • Has a prior medical history of eosinophilic colitis.

    • Participants with abdominal abscess, fulminant disease, or toxic megacolon.

    • Participants with intestinal failure or short bowel syndrome.

    • Presence of symptomatic colonic or small bowel obstruction, confirmed by objective radiographic or endoscopic evidence of a stricture with resulting obstruction (dilation of the colon or small bowel proximal to the stricture on barium radiograph or an inability to traverse the stricture at endoscopy).

    • History of extensive colonic resection (eg, less than 30 cm of colon remaining) that would prevent adequate evaluation of the effect of study agent on clinical disease activity.

    • History of colonic mucosal dysplasia or presence of adenomatous colonic polyps not removed OR presence of colonic mucosal dysplasia or adenomatous colonic polyps not removed during colonoscopy at screening visit.

    • If the participant has extensive colitis for ≥8 years or disease limited to left side of colon (ie, distal to splenic flexure) for >10 years, regardless of age, a colonoscopy within 1 year of the screening visit is required to survey for dysplasia. Participants with dysplasia or cancer identified on biopsies will be excluded.

    • Diagnosis of indeterminate colitis, microscopic colitis, ischemic colitis, or Crohn's disease or clinical findings suggestive of Crohn's disease.
