Brief Summary:

The objective of the study is to evaluate two therapeutic strategies: "early switch" or "therapeutic intensification" in patients with spondyloarthritis in case of secondary treatment failure suspicion to a first monoclonal antibodies anti-TNF definite by increase of ASDAS and positivity to ADAb.

Patients and Methods:

Multicentric randomized prospective study. Duration of inclusion 30 months. Duration of follow-up 24 months. 104 patients with spondyloarthritis treated with infliximab or adalimumab will be included if their ADAb dosage is positive, and they will be randomized (1:1) in two groups : "early switch" where treatment will be change to another anti-TNF, or "therapeutic intensification" where interval between two injections will be shortened. Patients will be evaluated clinically (ASDAS) and biologically (ADAb) at 12 weeks then at 24 weeks. Principal outcome will be the variation of ASDAS between baseline and end of the study. Number of patients to be included has been determined statistically from a preliminary study (power >98% for ASDAS variation of 20% on week 24).

Expected results:

On week 24, we expect a better response and a greater proportion of patients in remission in the "early switch" arm compare to the "therapeutic intensification" arm.

Arm Intervention/treatment
Experimental: early switch
  • early switch of monoclonal antibodies anti-TNF
  • anti drug antibodies dosage
Biological: anti drug antibodies dosage
anti drug antibodies dosage

Experimental: therapeutic intensification
  • therapeutic intensification of monoclonal antibodies anti-TNF
  • anti drug antibodies dosage
Biological: anti drug antibodies dosage
anti drug antibodies dosage

Primary Outcome Measures :
  1. Variation of ASDAS between inclusion and 24 weeks of treatment [ Time Frame: Week 24 ]
    ASDAS will be measured at week 24 and will be compared to day 1

Secondary Outcome Measures :
  1. Frequency of patients with ASDAS < 2.1 [ Time Frame: Week 24 ]
    Frequency of patients with ASDAS < 2.1 at week 24 ASDAS < 2.1 is considered as remission

Other Outcome Measures:
  1. Safety analysis - Occurence of adverse event [ Time Frame: Week 24 ]
    safety analysis in each arm at week 24 Safety analysis include occurence of adverse event in each arm
