E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To identify new candidate genes that are differentially expressed in responders’ vs non-responders to anti-TNF alpha therapy at the several time points we will use the transcriptomic and proteomic analyses |
|
E.2.2 | Secondary objectives of the trial |
1) QoL evaluation 2) MRI progression under TNF-alpha therapy |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• AS according to SPR guidelines (1984 modified New York Criteria, but allowing the use of MRI as imagiological criteria) • Patient enrolment followed national guidelines for TNF antagonist use for the treatment of AS • Adults between 18 to 75 years • Ability to provide informed consent • Corticosteroid therapy allowed (equivalent to ≤ 10 mg prednisone) and / or NSAID, dose stable in 4 weeks before study iniciation • Adequate contraception (barrier or hormonal) in men and women of childbearing age (patients and their partners • Adequate renal and hepatic function (2 times ULN)
