简要总结
The purpose of this study is to evaluate the pharmacokinetics (the study of the way a drug enters and leaves the blood and tissues over time) of golimumab administered intravenously (IV) to pediatric participants with polyarticular (affects 5 or more joints) juvenile (an onset before age 16) idiopathic (of unknown cause) arthritis (joint pain) (pJIA) manifested by greater than or equal to (>=) 5 joints with active arthritis despite methotrexate (MTX) therapy for >= 2 months.
详细描述
This is a single arm, Open-label (all people know the identity of the intervention), multi-center (when more than one hospital or medical school team work on a medical research study) study to determine the pharmacokinetics (the study of the way a drug enters and leaves the blood and tissues over time), efficacy (effectiveness) and safety of intravenous golimumab in participants with pJIA despite current treatment with methotrexate (MTX). The study will consist of 3 parts: Screening Phase (6 weeks); an Open-label Treatment Phase (consists of golimumab and MTX treatment for 52 weeks, wherein after Week 28, MTX dose change is allowed); Long-term Extension Phase (after Week 52 through Week 252) and Extended Treatment Period (after week 252). The maximal study duration for a participant will not exceed 832 weeks. All the eligible participants will be administered golimumab IV infusion and commercial MTX. Blood samples will be collected for evaluation of pharmacokinetics of study treatment. Participants' safety will be monitored throughout the study.

入选标准
- •Diagnosis must be made per Juvenile Idiopathic Arthritis (JIA) International League of Associations for Rheumatology (ILAR) diagnostic criteria and the onset of disease must have been before the participant's 16th birthday
- •Failure or inadequate response to at least a 2 month course of methotrexate (MTX) before screening
- •Participants must have greater than or equal to (>=) 5 joints with active arthritis at screening and at Week 0 as defined by American College of Rheumatology (ACR) criteria (that is, a joint with either swelling, or in the absence of swelling, limited range of motion associated with pain on motion or tenderness)
- •Participants must have a screening C-reactive protein (CRP) of >=0.1 milligram (mg)/deciliter (dL) with the exception of approximately 30 percent (%) of the study population
- •Participants must have active polyarticular juvenile idiopathic arthritis (pJIA) despite current use of oral, intramuscular, or subcutaneous MTX for >=2 months before screening. For participants with body surface area (BSA) less than (<)1.67 meter square (m^2), the MTX dose must be between 10 to 30 milligram per meter square (mg/m^2) per week and stable for >=4 weeks before screening. For participants with BSA >=1.67 m^2, the MTX dose must be a minimum of 15 mg/week and must be stable for >=4 weeks before screening. In situations where there is documented intolerance of doses greater than (>)10 mg/m^2 weekly (for participants with BSA <1.67 m^2) or >=15 mg/week (for participants with BSA >=1.67 m^2); or where documented country or site regulations prohibit use of >=15 mg of MTX per week in participants with BSA >=1.67 m^2, participants may be entered into the trial on a lower dose of MTX
排除标准
- •Participant has initiated disease-modifying antirheumatic drugs (DMARDs) and/or immunosuppressive therapy within 4 weeks prior to first study agent administration
- •Participant has been treated with intra-articular, intramuscular or intravenous corticosteroids (including intramuscular corticotropin) during the 4 weeks before first study agent administration
- •Participant has been treated with any therapeutic agent targeted at reducing Interleukin (IL)-12 or IL 23, including but not limited to ustekinumab and ABT-874, within 3 months before first study agent administration
- •Participant has been treated with natalizumab, efalizumab, or therapeutic agents that deplete B or T cells (eg, rituximab, alemtuzumab, or visilizumab) during the 12 months before first study agent administration, or have evidence at screening of persistent depletion of the targeted lymphocyte after receiving any of these agents
- •Participant has been treated with alefacept within 3 months before first study agent administration
- •If a participant has been previously treated with an anti-tumor necrosis factor alpha (TNF alpha) agent, the reason for discontinuation of the anti-TNF alpha agent cannot have been a severe or serious adverse event consistent with the class of anti-TNF alpha agents
研究组 & 干预措施
Golimumab + Methotrexate
Participants will receive 80 milligram per meter square (mg/m^2) as an intravenous (IV) infusion at Weeks 0, 4, and every 8 weeks thereafter up to Week 244, along with commercial methotrexate (MTX) weekly through Week 28 at the same Body Surface Area (BSA)-based dosage (10 to 30 mg/m^2 per week for participants with BSA less than [<] 1.67 meter square (m^2), or minimum of 15 mg/week for participants with BSA greater than or equal to [>=] 1.67 m^2) as at the time of study entry. At Week 252, participants who meet the criteria for the optional Extended Treatment Period (ETP) may continue treatment with golimumab 80 mg/m^2 every 8 weeks after completion of the Week 252 assessments.
