Brief Summary:
The purpose of this study is to demonstrate that patients with Spondylarthropathies in remission under antiTNF therapy, can maintain the remission with a maintenance dose inferior to the currently recommended dose schedule.

Condition or disease Intervention/treatment Phase
Spondylarthropathies Drug: Reduced doses of anti-TNF Drug: Stable doses of anti-TNF Phase 4

Detailed Description:
It has been shown that the withdrawal of treatment follows with a flare of the disease in a short time after the suspension but it has not been evaluated in controlled trials if remission could be maintained with a lower dose. A multicenter, national, open-label, randomized and controlled clinical trial of 3 years duration (2 years for inclusion + 1 year follow-up) is proposed to address this issue. The study will include 190 patients with Spondylarthropathies in stable treatment with any single anti-TNF agent and compliance with criteria of clinical remission for at least 4 months. Patients will be randomized to intervention or control arm, with stratification according to the antiTNF product thet were receiving prior to inclusion. Patients will be followed with the calendar of visits recommended by the Spanish Society of Rheumatology for clinical practice. The proposed hypothesis is of non-inferiority of the experimental arm with dose reduction versus the control arm with standard treatment.
