GIS-SUSANTI-TNF-2015 (Anti-TNF Discontinuation )

A multicentre prospective randomized trial.

Hypothesis:

The discontinuation of anti-TNF treatment in inflammatory bowel disease (IBD) patients in clinical remission is associated with an increased risk of recurrence compared with maintaining such treatment.

Main objective:

To assess the percentage of patients with IBD who, after stopping anti-TNF treatment, have sustained clinical remission at one year compared to those in which the treatment is continued at stable doses

Secondary objectives:

To compare treatment discontinuation vs. treatment continuation of anti-TNF agents in patients with Crohn´s disease or ulcerative colitis in terms of:

1. remission (relapse-free) time,
2. phenotype changes with both strategies
3. mucosal healing,
4. radiologic healing
5. impact on quality of life and productivity
6. safety
7. to identify relapse predictive factors.
8. To identify relapse predictive factors after anti-TNF drug discontinuation
9. Determining the profile of serum cytokines in patients with both strategies, depending on drug exposure and if maintained clinical remission or relapse.

Planned number of subject to be included: 194

The participation of at 50 hospitals in Spain with an inclusion of about 5 patients per hospital is required..
