E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to evaluate the sustained deep remission rate one year after discontinuation of a 12-month course of adalimumab in adult patients with early Crohn's disease (CD) who achieved deep remission at 12 months AND who were already in clinical remission (CDAI < 150) and biomarker remission (CRP < 5 mg/L and fecal calprotectin < 250) at 6 months |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of this study are:
- To assess predictors of loss of deep remission during the year following treatment withdrawal in patients who achieved remission, after 1 year adalimumab course.
- To estimate the 2-year deep remission rate in patients who did not achieve 1-year deep remission,
- To assess efficacy and tolerability of a 12-month adalimumab course,
- To assess efficacy and tolerability of a 12-month retreatment with adalimumab following CD reactivation.
- To assess the impact of an early treatment with adalimumab on longterm clinical outcomes (bowel damage, CD-related surgeries, hospitalizations, patient's reported outcomes such as fatigue, disability and quality of life) by following all patients for 5 years after study inclusion. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary study endpoint will be the percentage of patients with sustained deep remission 12 months after a 12-month course of adalimumab in patients who achieved deep remission without therapeutic intervention (i.e. no surgery, no clinical flare-up, no introduction of CD-related treatment, no need for adalimumab optimization) AND who were already in clinical remission (CDAI < 150) and biomarker remission (CRP < 5 mg/L and fecal calprotectin < 250µg/g) at 6 months. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |

• Deep remission rate after a 24-month course of adalimumab in patients who did not experience deep remission after a 12-month course of adalimumab,
• Deep remission rate after a 36-month course of adalimumab in patients who were not in deep remission after a 24-month course of adalimumab,
• Time to first clinical relapse after adalimumab discontinuation,
• Changes in CDAI over the study,
• Changes in CRP and fecal calprotectin over the study,
• Change from baseline in CDEIS score at 12-month and 5-year,
