About this trial

This is an interventional treatment trial for Ankylosing Spondylitis

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Key Inclusion Criteria:

  • Diagnosis of ankylosing spondylitis according to the Modified New York Criteria (1984).
  • Inadequate response to at least 2 weeks of continuous treatment with NSAIDs, or unable to receive ≥ 2 full weeks of continuous treatment with NSAIDs because of intolerance.
  • If previously treated with a biological agent, patient must not have failed due to lack of efficacy, and must have completed an appropriate washout period prior to first dose of study drug.
  • Patients may continue on specified stable background therapies for ankylosing spondylitis (doses should be stable for at least 4 weeks prior to the first dose of study drug).
  • Additional criteria exist.

Key Exclusion Criteria:

  • Diagnosis of any other active or uncontrolled inflammatory or non-inflammatory articular disease that may interfere with disease activity assessments.
  • Previously treated with intravenous immunoglobulins within 6 months prior to first dose of study drug.
  • Patients requiring prohibited concomitant medications including moderate or strong CYP3A inhibitors, CYP3A inducers and Biologic Response Modifiers (BRMs) while on study.
  • Trauma or other major surgeries within 8 weeks prior to first dose of study drug.
  • Specific abnormal laboratory values or electrocardiogram abnormalities.
  • Known positive serology for human immunodeficiency virus (HIV), hepatitis C, and/or hepatitis B.
  • Additional criteria exist.
