Exclusion criteria
Exclusion criteria: Specific medical exclusion criteria: 1. Definite AS (modified New York criteria (9)); 2. Previous treatment with TNF-blockers. General medical exclusion criteria: 1.

Documented seropositive for human immunodeficiency virus (HIV); 3. Documented positive for hepatitis B surface antigen or hepatitis C; 4. History of alcohol or substance abuse within the preceding 6 months that, in the opinion of the investigator, may increase the risks associated with study participation or study agent administration, or may interfere with interpretation of results; 5. Known history of serious infections (e.g., herpes zoster, cytomegalovirus, pneumocystis carinii, aspergillosis, histoplasmosis, coccidioidomycosis or mycobacteria other than TB) within 6 months prior to screening; 6. History of lymphoproliferative disease, including lymphoma or signs suggestive of possible lymphoproliferative disease such as lymphadenopathy of unusual size or location (e.g., nodes in the posterior triangle of the neck, infraclavicular, epitrochlear, or periaortic area), or splenomegaly; 7. Any current known malignancy or history of malignancy within the previous 5 years, with the exception of basal cell or squamous cell carcinoma of the skin that has been fully excised with no evidence of recurrence; 8. Any current signs or symptoms of severe, progressive or uncontrolled renal, hepatic, hematologic, gastrointestinal, endocrine, pulmonary, cardiac, neurologic, or cerebral disease; 9. History of known demyelinating diseases such as multiple sclerosis or optic neuritis; 10. Being unable or unwilling to undergo multiple venipunctures because of poor tolerability or lack of easy access; 11. Use of any investigational drug within 30 days prior to screening or within 5 half-lives of the investigational agent, whichever is longer; 12.
