NCT03322618

Brief Summary

the main objectives are

  1. 1.to study the pathophysiological role of KIR3DL2 in axSpA and its relationship with Th17 immunity in HLA-B27 + and HLA-B27- patients and
  2. 2.to assess the effect on the pro-inflammatory immune response of a cytotoxic monoclonal antibody IPH4102 (anti-KIR3DL2) in these patients.

Outcome Measures

Primary Outcomes (1)

  • Characterize the present various immunizing populations in patients' blood SPA HLA-B27 + and HLA-B27-(Lymphocytes T CD4 (Th1 Th2, Th17, Tregs), lymphocytes T CD8, cells NK, lymphocytes B, monocytes)

    by flow cytometry.
