Current pharmacological management of inflammatory rheumatism and in particular axial SpA remains imperfect. Only 50% of patients respond to the most effective biotherapies, and many of them are only partially relieved. In addition, these are extremely expensive treatments that expose them to the risk of potentially serious side effects. Compelling evidence indicates that gut dybiosis could be a critical trigger of inflammation in axial SpA and thus correcting dysbiosis represents an attractive way of reversing the pathogenic process.The efficacy of FMT in patients with axial SpA has never been studied. This randomized double-blind study will be the first to assess feasability of FMT in axial SpA, the capacity of this procedure to restore healthy microbiome, its tolerance and its potential efficacy on disease activity. If sucessfull, this trial would set the path to larger-scale clinical trials of FMT to treat axial SpA.
Two-co primary objectives in a hierarchical design:
* to evaluate the capacity of FMT to correct dysbiosis in active axial SpA despite well-conducted phamacological treatment by replacing pre-existing dysbiotic microbiota with healthier microbiota. * to explore the efficacy of FMT versus placebo on clinical evolution of SpA.
Adult patient (age 18 to 75 years old) with SpA, meeting the ASAS classification criteria for axial SpA, with presence of radiographic sacro-illitis (ankylosing spondylitis) or not.
Patient suffering of active SpA, with or without treatment, having a BASDAI score ≥ 4 (0-10) at baseline and a score of back pain ≥ 4 (0-10) despite optimal drug management for at least 6 months including at least 2 different NSAIDs at the maximum tolerated dose for at least 2 months (or less in case of intolerance or contra-indication) and at least a first line of biotherapy (anti-TNFα or anti-IL-17) for at least 4 months (or less in case of intolerance or contra-indication).
Subjects are allowed to continue NSAID, sulfasalazin (≤ 3 g/day) and/or methotrextae ( ≤ 25 mg/week) and/or hydroxychloroquine (≤ 400 mg/day) and/or oral corticosteroid (≤ 10 mg/day of prednisone), as long as these treatments have remained at stable dose for 4 weeks prior to baseline.
Subjects are allowed to continue anti-TNFα, anti-IL-17 or JAKinhibitor therapies, as long as these treatments have remained at stable dose for 3 months prior to baseline.
Patient under legal protection (guardianship or curatorship)
Subject who, in the judgment of the Investigator, is likely to be non-compliant or uncooperative during the study, or unable to cooperate because of a language problem, poor mental development
Pregnant or breastfeeding woman
Patient with IBD in active state, according to the judgment of the Investigator
