A Study of Tocilizumab (RoActemra/Actemra) in Patients With Ankylosing Spondylitis Who Have Had an Inadequate Response to Previous Tumor Necrosis Factor (TNF) Antagonist Therapy

• Status: Terminated
• Trial end date: 2011-12-01

Summary

This randomized, double-blind, placebo-controlled study evaluated the safety and efficacy of tocilizumab (RoActemra/Actemra) in patients with ankylosing spondylitis (AS) who had an inadequate response to previous tumor necrosis factor (TNF) antagonist therapy. Patients were randomized to receive tocilizumab at a dose of either 8 mg/kg or 4 mg/kg intravenously (iv) or placebo every 4 weeks for 24 weeks. The double-blind treatment period was followed by open-label treatment with tocilizumab 8 mg/kg iv every 4 weeks until Week 104 for all patients.

This study and all further clinical development of tocilizumab AS was halted after a review of 12-week data from Study NA22823, a randomized double-blind, placebo-controlled study in TNF antagonist naïve AS patients, failed to demonstrate efficacy.
