Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Transmural response (TR25) | From week 0 to week 24 | Transmural response (TR25) define as the decrease of at least (\>=) 25% of C-score in each and all active segment from baseline to week 24 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical remission | Week 0, Week 4, Week 8, Week 12, Week 24, Week 52, Week 76 | Clinical remission will be defined according to PRO-2 (Patient Report Outcome) |
| Improvement or normalization of bowel urgency | Week 0, Week 4, Week 8, Week 12, Week 24, Week 52, Week 76 | Improvement or normalization of bowel urgency according to UNRS (Urgency Numerical Rating Scale) |
| BU clinical meaningful improvement | Week 0, Week 4, Week 8, Week 12, Week 24, Week 52, Week 76 | BU clinical meaningful improvement was defined as decrease of \>=3 points; BU Remission was defined as UNRS =\<2 |
| Transmural response (TR50) | Week 0, Week 24, Week 76 | Transmural response (TR50) is defined as a decrease of at least 50% of C-score in each active segment at baseline |
| Transmural healing | at Week 0, Week 24, Week 76 | Transmural healing is defined as a C-score \< 0.5 in each active segment at baseline |
| Disease activity | Week 0, Week 24, Week 76 | Disease activity is measured by the MaRIA score (Magnetic Resonance Index of activity) |
| IUS transmural response/healing | Week 4, Week 8, Week 12, Week 24 | IUS transmural response/healing |
| Bowel damage | Week 24, Week 76 | Bowel damage is measured with the Lemann Index |
| Transmural response (TR25) | Week 0, Week 4, Week 24, Week 76 | Transmural response will be defined as a decrease of at least 25% of C-score in each active segment at baseline |
