Design outcomes

Primary

MeasureTime frame
Main Objective: 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;Secondary Objective: 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;Primary end point(s): The primary efficacy endpoint is the ASAS20 response rate at Week 12.
