Outcome Measures
Primary Outcome Measures
- 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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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'.
- Incidence of treatment-emergent adverse events (TEAEs) or serious adverse events (SAEs) [Baseline up to Week 64]
- Concentration of dupilumab in serum over time. [Baseline up to Week 52]
- Incidence of treatment-emergent antidrug antibodies (ADA) against dupilumab. [Baseline up to Week 64]
- 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.

-

-
Participants with intestinal failure or short bowel syndrome.
-

-
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.
-
