E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the: • Efficacy of treatment with TCZ 4 mg/kg and 8 mg/kg versus placebo in AS patients who have had an inadequate response to TNF antagonist therapy with regard to the proportion of patients who achieve an ASAS20 response at week 12 (confirmation at week 24) • Safety of TCZ 4 mg/kg and 8 mg/kg versus placebo with regard to AEs and laboratory assessments |
|
E.2.2 | Secondary objectives of the trial |
To assess the: • Long term safety and efficacy of TCZ in patients with AS • Pharmacokinetics and pharmacodynamics of TCZ in patients with AS • Immunogenicity of TCZ in patients with AS |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
adult patients, >/=18 years of age
diagnosis of definite ankylosing spondylitis, defined by modified New York criteria, ≥ 3 months prior to baseline
active disease defined as BASDAI score of ≥ 4.0 and spinal pain assessment score of ≥40, on a 0-100 mm Visual Analogue Scale (VAS), at screening and baseline
inadequate response or intolerant to 1 or more current or previous NSAIDs
inadequate response or to treatment with etanercept, infliximab, adalimumab or golimumab because of inadequate efficacy (etanercept ≥ 3 months at 25 mg twice a week or 50 mg weekly; at least 3 months of infliximab at ≥ 5 mg/kg; adalimumab at a minimum of 40 mg every other week for ≥ 3 months, or 4 subcutaneous injections of golimumab at 50 mg monthly).
at screening, CRP greater than ULN

|
E.4 | Principal exclusion criteria |
previous treatment with tocilizumab
inflammatory rheumatic disease other than AS (psoriatic arthritis is allowed if patient also has definite AS as defined in inclusion criteria)
total ankylosis of spine
active, acute uveitis at baseline
major surgery (including joint surgery) within eight weeks prior to screening or planned major surgery within six month after randomisation
