E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective was to determine the long-term safety of etanercept administered with or without other disease-modifying anti-rheumatic drugs (DMARDS) in pediatric subjects with polyarticular course or systemic juvenile rheumatoid arthritis (JRA) compared to a control cohort of subjects with polyarticular course or systemic JRA receiving methotrexate (with or without other DMARDS)
|
|
E.2.2 | Secondary objectives of the trial |
There were no secondary objectives |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Boys or girsl agew 2 to 18 years (inclusive) with a diagnosis of systemic, polyarticular, or pauciarticular JRA defined by the American College of Rheumatology (ACR) criteria.
• Duration of disease long enough for the subject to have been given an adequate trial of nonsteroidal anti-inflammatory drug (NSAID) and/or prednisolone.
• Co-administration of other DMARDS that did not specifically inhibit TNF (eg: infliximab, thalidomide, D2E7 [adalimumab]).
• Parent or legal guardian able and willing to give informed consent.
• Disease course must have been polyarticular or systemic with active arthritis in greater than or equal to 3 joints at the time of starting methotrexate alone or methotrexate in combination with other DMARDS, etanercept alone or etanercept added to ongoing methotrexate or other DMARDS.
• Pre-pubescent, or if post-pubertal at any time during the study and of childbearing potential must practice adequate contraception
Etanercept Arm
• Newly started etanercept or began etanercept within 6 months of enrollment into the study. Subjects who entered the study from selected Immunex protocols and may have received etanercept for up to 1 year had their time of exposure counted from the first dose of etanercept in the original Immunex study.
Methotrexate Arm
• Newly started methotrexate or began methotrexate within 6 months of enrollment into the study.
|
|
E.4 | Principal exclusion criteria |
• Pregnant or nursing
• Receipt of antibody to TNF (infliximab, adalimumab, or other anti-TNF), antibody to CD4 (anti CD4), or diphtheria interlukin-2 fusion protein (DAB-IL-2).
• Participation in a study of an investigational drug or biologic other than etanercept that required informed consent ≤ 6 months.
• Receipt of any of the following DMARDS: TNF inhibitors other than etanercept such as infliximab, thalidomide, adalimumab, cyclophosphamide, experimental agents; or other biologic agents
• Any serious concurrent medical condition, either acute or chronic, which would compromise the subject’s ability to cooperate with the protocol requirements.
• History of alcohol or drug abuse
• Prior malignancies unless the subject had been disease-free for at least 5 years.
• Serious concurrent medical conditions, either acute or chronic (including infections) that prevent the subject from receiving a TNF inhibitor.

E.5 End points |
E.5.1 | Primary end point(s) |
Endpoints were not designated as primary or secondary. Study endpoints were:
• Adverse event rates(including infection)and severity compared between treatment cohorts
• Growth data (height, weight, age, and height percentile) and Tanner scores (at selected sites, approximately 30% of subjects) compared between treatment cohorts and to national norms
• Occurrence of any new autoimmune disease
• Cancer rates for each treatment cohort
• Child Behavior Checklist sub-scales and total scores compared to baseline and between treatment arms
