This randomized, double-blind, placebo-controlled study will evaluate the safety and efficacy of RoActemra/Actemra (tociliumab) in patients with ankylosing spondylitis who have failed treatment with non-steroidal anti-inflammatory drugs and are na´ve to TNF antagonist therapy. In Part 1 of the study, patients will be randomized to receive either RoActemra/Actemra 8 mg/kg intravenously (iv) or placebo every 4 weeks for 12 weeks. In Part 2, patients will be randomized to receive RoActemra at either 8 mg/kg or 4 mg/kg iv or placebo every 4 weeks for 24 weeks. The double-blind treatment period will be followed by open-label treatment with RoActemra/Actemra 8 mg/kg iv every 4 weeks until Week 208 for all patients. Anticipated time on study treatment is 208 weeks.

Clinical Details

Official title: A Ph II/III Seamless, Multi-center, Randomized, Double-blind, Placebo-controlled Study of the Reduction in Signs and Symptoms and Inhibition of Structural Damage During Treatment With Tocilizumab Versus Placebo in Patients With Ankylosing Spondylitis Who Have Failed Non-steroidal Anti-inflammatory Drugs and Are na´ve to TNF Antagonist Therapy

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Primary outcome:

Proportion of patients achieving response of 20% improvement in ASsessment in AS International Working Group criteria (ASAS20)

Safety: Adverse events, laboratory parameters

Secondary outcome:

Radiographic change according to the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS) and the Radiographic Ankylosing Spondylitis Spinal Score (RASSS)

Change in physical function according to the Bath Ankylosing Spondylitis Functional Index (BASFI) and the Bath Ankylosing Spondylitis Metrology Index (BASMI)

Long-term efficacy (BASDAI, BASFI, BASMI)

Pharmacokinetics and pharmacodynamics (tocilizumab AUC, Cmax, T1/2, Cl, V; Interleukin-6; Soluble Il-6 receptor)
