Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Diagnosis of AS, as defined by Modified New York Criteria for Ankylosing Spondylitis.
  • Active AS, defined by average of visual analog scale (VAS) of ≥ 30 for duration and intensity of morning stiffness and at least 2 of the following: VAS for patient global assessment ≥ 30; average of VAS for nocturnal and total pain ≥ 30; BASFI ≥ 30 (all scores on a scale of 0 to 100).

Exclusion Criteria:

  • Complete ankylosis (fusion) of spine.
  • Previous treatment with etanercept, antibody to Tumor Necrosis Factor α (TNFα), or other TNFα inhibitors or other biologic agents.
  • Use of disease modifying antirheumatic drugs (DMARDs) other than hydroxychloroquine, sulphasalazine, and methotrexate within 4 weeks of baseline. Subjects treated with hydroxychloroquine, sulphasalazine, and methotrexate may continue these drugs during this study but doses must be held stable for 4 weeks before baseline examination and for the duration of the study.
  • Receipt of multiple nonsteroidal anti-inflammatory drugs (NSAIDs) at baseline.
  • Dose of NSAID changed within 2 weeks of baseline evaluation.
  • Dose of prednisone >10 mg/day (or equivalent) or changed within 2 weeks of baseline evaluation.
