Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Steroid-free clinical and biochemical remission | Month 6 | Normalization of faecal calprotectin (\< 250 µg/g) and steroid-free clinical remission, defined as patient PRO2 ≤ 8 (average daily stool frequency ≤ 1.5 AND average daily abdominal pain score ≤ 1), at month 6. |
Secondary
