A Study of the Safety and Effectiveness of Infliximab (Remicade) in Patients With Juvenile Rheumatoid Arthritis

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the effectiveness and safety of infliximab (Remicade) in patients with Juvenile Rheumatoid Arthritis (JRA).

Detailed Description
-----------------
The purpose of this study is to determine if infliximab in combination with methotrexate is safe and effective in the treatment of patients with juvenile rheumatoid arthritis. The second purpose of this study is to see how children's bodies react to the combination of study drug and methotrexate. Patients will receive either infliximab at 3 mg/kg for 44 weeks or, placebo for 14 weeks followed by infliximab at 6 mg/kg for 30 weeks. Patients who complete the original study are eligible for additional treatment with 3 to 6 mg/kg of infliximab every 8 weeks for up to three years. Safety evaluations will be performed at specified intervals throughout the study and will consist of laboratory tests, vital signs (such as blood pressure), physical examinations and the occurrence and severity of adverse events as well as other study specific procedures. Patients will receive either infliximab at 3 mg/kg for 44 weeks or, placebo for 14 weeks followed by infliximab at 6 mg/kg for 30 weeks. Patients who complete the original study are eligible for additional treatment with 3 to 6 mg/kg of infliximab every 8 weeks for up to three years

Official Title

Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Patients must have a diagnosis of juvenile rheumatoid arthritis (JRA) with polyarticular JRA for at least 6 months, systemic JRA with a polyarticular course and no systemic symptoms (including fever, rash,hepatosplenomegaly, and serositis) for 1 year prior to study entry, or pauciarticular JRA with a polyarticular course for at least 6 months prior to study entry. The patient should have had at least 6 months of persistent synovitis before screening. The patient must have at least 5 joints with active arthritis (ie, presence of swelling, or if no swelling is present, limitation of motion accompanied by pain, tenderness, or both) at the time of enrollment, with at least 3 of these active joints having limitation of motion accompanied by pain, tenderness, or both The patient must be at least 4 years of age, but less than 18 years (ie, after the 4th but before the 18th birthday), with onset of disease before age 16. Exclusion Criteria: Patient must not be pregnant, nursing, or planning a pregnancy within 6 months after the last study infusion Patient must not be incapacitated, largely or wholly bedridden, or confined to a wheelchair, or have little or no ability for age-appropriate self care Patient must not have a rheumatic disease other than JRA or any current systemic inflammatory condition (for example, Lyme disease,fibromyalgia, enthesitis-related arthritis, psoriatic arthritis, systemic lupus erythematosus, infectious or reactive arthritis, Reiter's syndrome, or parvovirus infection)

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The proportion of patients with improvements in the Juvenile Rheumatoid Arthritis core set criteria at Week 14 in the placebo group with that in the 3 mg/kg infliximab plus concomitant methotrexate therapy group. |  |  |
