Study to Evaluate the Efficacy and Safety of Filgotinib in the Treatment of Small Bowel Crohn's Disease (SBCD)

The CDAI score is used to quantify the symptoms of participants with Crohn's Disease (CD). The score ranges from 0 to 600. Clinical remission by CDAI was defined as a score of < 150. A higher score indicates more severe disease.

Magnetic resonance enterography (MRE) is an imaging technique to evaluate disease activity in CD. MaRIA is an MRE-based scoring system. The MaRIA scoring system is a composite index of 4 components. These components are edema, ulcers, gut wall thickness, and relative contrast enhancement (RCE). A segmental MaRIA score can be calculated at screening (used as the baseline) and Week 24 as a weighted sum of these components for the terminal ileum segment of the small bowel. A segmental score of ≥ 7 indicates active inflammation and a score of ≥ 11 indicates the presence of an ulcer. Segmental scores less than 7 indicate remission. The MaRIA score ranges from approximately 0 to 31, for any given segment. A higher score indicates more severe disease. Difference in least squared means (Diff in LSM) were from analysis of covariance (ANCOVA) model. A negative change from baseline indicates improvement and a positive change from baseline indicates disease worsening.

These components are edema, ulcers, gut wall thickness, and RCE. A segmental MaRIA score can be calculated at Screening (used as the baseline) and Week 24 as a weighted sum of these 4 components for the distal ileum segment of the small bowel. A segmental score of ≥ 7 indicates active inflammation and a score of ≥ 11 indicates the presence of an ulcer. Segmental scores less than 7 indicate remission in that segment. The MaRIA score ranges from approximately 0 to 31, for any given segment. A higher score indicates more severe disease. Diff in LSM were from ANCOVA model. A negative change from baseline indicates improvement and a positive change from baseline indicates disease worsening.

These components are edema, ulcers, gut wall thickness, and RCE. A segmental MaRIA score can be calculated at Screening (used as the baseline) and Week 24 as a weighted sum of these 4 components for the jejunum segment of the small bowel. A segmental score of ≥ 7 indicates active inflammation and a score of ≥ 11 indicates the presence of an ulcer. Segmental scores less than 7 indicate remission in that segment.

MaRIA remission was defined as a segmental MaRIA score < 7 in terminal ileum segment at Week 24 among participants with MaRIA score ≥ 7 in the same segment at baseline. A segmental score of ≥ 7 indicates active inflammation and a score of ≥ 11 indicates the presence of an ulcer.

MaRIA response was defined as a segmental MaRIA score < 11 with baseline score ≥ 11, or a segmental MaRIA score < 7 with baseline score < 11, or ≥ minimum detectable difference (MDD) units decrease from baseline score for segments with baseline MaRIA score ≥ 7 in the terminal ileum. For segments with baseline MaRIA score ≥ 15, the MDD is 6.5 units and for baseline MaRIA score < 15, the MDD is 4.0 units.
