Spondylitis, Ankylosing Clinical Trial
Official title:

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.

Eligibility |
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 - Traditional disease-modifying anti-rheumatic drugs (DMARDs) must be withdrawn for at least 4 weeks prior to baseline (methotrexate, sulfasalazine, and hydroxychloroquine or chloroquine may be allowed if at stable dose for at least 4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. |

Primary | Percentage of ASsessment in Ankylosing Spondylitis 20 (ASAS20) Responders at Week 12 | 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. | Baseline to Week 12 | No |
