Eligibility Criteria
Inclusion Criteria
- JIA subjects (male or female), ages 2-17 years with active disease who had an insufficient therapeutic response or intolerance to at least one non biologic DMARD or Tumor Necrosis Factor (TNFα) antagonists for at least 3 months prior to screening
- Subjects with TNFα inadequate response (or prior biologic) will be restricted to 30% of the population
- Subjects must have a history of at least 5 joints with active disease and must have currently active articular disease with ≥2 active joints and ≥2 joints with limitation of motion.
Exclusion Criteria
- Subjects with other rheumatic diseases or major chronic inflammatory/immunologic diseases, active uveitis, systemic JIA with active systemic features (within a period of 6 months prior to enrollment), persistent Oligoarthritis JIA, or failed 3 or more TNFα antagonists or other biological DMARDs will be excluded.
- Active systemic disease: (ie, extra-articular features of systemic JIA including fever, rash, organomegaly) within a period of 6 months prior to randomization.
- Subjects who have failed more than two TNFα antagonists or other biologic DMARDs
