What this Trial Is About

The primary objective of this study is to evaluate the pharmacokinetics (PK) of olokizumab (OKZ) in patients with polyarticular juvenile idiopathic arthritis aged \>2 and \<18 years in two doses (64 mg or 48 mg every 4 weeks) depending on patient's weight. Secondary objectives are to evaluate the pharmacodynamic (PD) profile, the long-term efficacy and safety of olokizumab in patients with polyarticular juvenile idiopathic arthritis aged \>2 and \<18 years.
