A Multicenter, Open-label Study to Assess the Pharmacokinetics, Safety and Efficacy of Certolizumab Pegol in Children and Adolescents With Moderately to Severely Active Polyarticular-course Juvenile Idiopathic Arthritis (JIA).
The overall study consists of a Screening Period of up to 4 weeks and an Open-Label Treatment Period which will continue until the approval of the marketing application for the Polyarticular-course Juvenile Idiopathic Arthritis (JIA) indication in the study participant's country or region or until further notice from UCB (approximately 4-6 years duration; depending on region). A Final Visit will be conducted 12 weeks after last dose of study medication. Overall, study visits will occur monthly during the first 6 months and every 2 months afterwards. All patients will receive active treatment with Certolizumab Pegol. The dose will depend on actual weight. Home dosing will be allowed between study visits. If less than 50 % of the study population achieves an adequate response to the treatment (American College of Rheumatology Pediatric 30 % (PedACR30) response) at Week 16, the study will be entirely discontinued.
CZP will be administered subcutaneously as a fixed dose based on weight every 2 weeks (Q2W) or every 4 weeks (Q4W) throughout the study. CZP will be provided by UCB as a CZP 200 mg/ml solution for single subcutaneous (sc) injection, in a single use prefilled syringe (PFS). Each PFS contains an extractable volume of 0.25 mL, 0.5 mL or 1 mL of CZP solution. Eligible subjects will begin with 3 loading doses of CZP followed by a treatment dose for the duration of the study based on the weight range. Reduced CZP regimen (after implementation of protocol amendments 4 and 5): * 10 to \< 20 kg: Loading dose = 50 mg Q2W (1 x 0.25 mL sc); treatment dose = 50 mg Q4W (1 x 0.25 mL sc); * 20 to \< 40 kg: Loading dose = 100 mg Q2W (1 x 0.5 mL sc,); treatment dose = 50 mg Q2W (1 x 0.25 mL sc); * ≥ 40 kg: Loading dose = 200 mg Q2W (1 x 1.0 mL sc); treatment dose = 100 mg Q2W (1 x 0.5 mL sc);
