  Purpose

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.

Primary Outcome Measures:
  • Percentage of ASsessment in Ankylosing Spondylitis 20 (ASAS20) Responders at Week 12 [ Time Frame: Baseline to Week 12 ] [ Designated as safety issue: No ]
    ASAS20 was defined as an improvement of ≥ 20% and an absolute improvement of ≥ 10 units on a 0-100 visual analog scale (VAS) from Baseline to Week 12 in 3 of 4 domains: 1-Patient global assessment (with extremes labelled none and severe), 2-Pain assessment (average total and nocturnal pain scores with extremes labelled no pain and most severe pain), 3-Function (represented by the Bath Ankylosing Spondylitis (BAS) Functional Index [BASFI] average of 10 questions regarding ability to perform specific tasks with extremes labelled easy and impossible), and 4-Inflammation (average of the last 2 questions on the 6-question BAS Disease Activity Index [BASDAI] concerning morning stiffness intensity with extremes labelled none and very severe and duration between 0 and 2 or more hours); and the absence of deterioration (of at least 20% and absolute change of at least 10 units on a 0-100 mm scale) in the remaining domain.

Criteria

Inclusion Criteria:

  • Adult patients ≥ 18 years of age.
  • Ankylosing spondylitis as defined by the modified New York criteria for ≥ 3 months prior to baseline.
  • Active disease at screening and baseline (Bath Ankylosing Spondylitis Disease Activity Index [BASDAI] ≥ 4.0, spinal pain visual analog scale [VAS] ≥ 40).
  • Inadequate response or intolerant to 1 or more previous non-steroidal anti-inflammatory drugs (NSAIDs).
  • Inadequate response to treatment with etanercept, infliximab, adalimumab, or golimumab because of inadequate efficacy.
  • Tumor necrosis factor (TNF) antagonist therapy must have been discontinued at least 8 weeks prior to baseline (etanercept 4 weeks).
  • Traditional disease-modifying anti-rheumatic drugs (DMARDs) must be withdrawn for at least 4 weeks prior to baseline (methotrexate, sulfasalazine, and hydroxychloroquine or chloroquine may be allowed if at stable dose for at least 4 weeks prior to baseline).
  • Oral corticosteroids (≥ 10 mg/day prednisone or equivalent) and NSAIDs/cyclooxygenase-2 [COX-2] inhibitors must be at stable dose for at least 4 weeks prior to baseline.

Exclusion Criteria:

  • Major surgery (including joint surgery) within 8 weeks prior to screening or planned major surgery within 6 months after randomization.
  • Total ankylosis of spine (as determined by investigator).
  • Inflammatory rheumatic disease other than ankylosing spondylitis.
  • Active, acute uveitis at baseline.
  • Previous treatment with tocilizumab.
  • Intra-articular or tendon injections or parenteral corticosteroids within 4 weeks prior to screening.
  • History of severe allergic or anaphylactic reactions to humanized or murine monoclonal antibodies.
  • Active current or history of recurrent bacterial, viral, fungal, mycobacterial, or other infection.
  • History of or currently active primary or secondary immunodeficiency.
  • Body weight > 150 kg.
