A Study of Secukinumab to Evaluate Maintenance of Response in Participants With Non-radiographic Axial Spondyloarthritis Who Achieved Remission


About the study

This study will establish whether prolonged chronic dosing with secukinumab is needed in participants with Non-radiographic axial spondyloarthritis, (nr-axSpA) who have achieved remission. Remission is defined as Ankylosing Spondylitis Disease Activity Score - C-reactive protein (ASDAS-CRP) Inactive Disease (ID) response (ASDAS-CRP < 1.3). Maintenance of remission on continued secukinumab treatment will be evaluated compared to placebo using a randomized withdrawal design. The primary outcome measure for this study is the proportion of participants remaining flare-free at Week 120.

Who can take part

You may be eligible to participate in the study if you meet the following criteria:


Inclusion Criteria:

Male or non-pregnant, non-lactating female participants at least 18 years of age

Clinical diagnosis of axSpA AND according to ASAS axSpA criteria:

  1. Inflammatory back pain for at least 6 months
  2. Onset before 45 years of age
  3. Sacroiliitis on MRI (magnetic resonance imaging) (as assessed by central reader) with ≥ 1 SpA feature OR HLA-B-27 positive with ≥2 SpA features
  4. Objective signs of inflammation at screening, evident by either MRI with Sacroiliac Joint inflammation (as assessed by central reader) AND / OR hsCRP > ULN (as defined by the central lab)
  5. Active axSpA as assessed by total BASDAI ≥ 4 cm (0-10 cm) at baseline.
  6. Spinal pain as measured by BASDAI question #2 ≥ 4 cm (0-10 cm) at baseline.
  7. Total back pain as measured by VAS (visual analog scale) ≥ 40 mm (0-100 mm) at baseline.
  8. Participants should have been on at least 2 different NSAIDs (non-steroidal anti-inflammatory drugs) at the highest recommended dose for at least 4 weeks in total prior to baseline with an inadequate response or failure to respond, or less if therapy had to be withdrawn due to intolerance, toxicity or contraindications.


Exclusion Criteria:

  1. Participants with radiographic evidence for sacroiliitis, grade ≥ 2 bilaterally or grade ≥ 3 unilaterally (radiological criterion according to the modified New York diagnostic criteria for AS) as assessed by central reader.
  2. Participants taking high potency opioid analgesics (e.g., methadone, hydromorphone, morphine).
  3. Previous exposure to secukinumab or any other biologic drug directly targeting IL-17 or IL-17 receptor or previous treatment with immunomodulatory biologic agents including those targeting TNFα (tumor necrosis factor α) (unless participants discontinued the treatment with TNFα inhibitor due to a reason other than efficacy [primary or secondary lack of efficacy, inadequate response] and only after appropriate wash-out period prior to baseline was observed).
  4. History of hypersensitivity to the study drug or its excipients or to drugs of similar chemical classes.
  5. Active ongoing inflammatory diseases other than nr-axSpA that might confound the evaluation of the benefit of secukinumab therapy, including uveitis.
  6. Active inflammatory bowel disease.
  7. History of ongoing, chronic or recurrent infectious disease or evidence of tuberculosis infection.
