Summary:

      Patients with active Axial Spondyloarthritis without x-ray evidence of Ankylosing Spondylitis
      and with signs of inflammation will be randomly assigned to receive certolizumab pegol (CZP)
      200 mg every two weeks or placebo. The primary objective is to demonstrate the efficacy of
      CZP in these patients.
