Safety and Efficacy Study of Etanercept (Enbrel®) In Children With Systemic Onset Juvenile Rheumatoid Arthritis

Information source: Amgen
Information obtained from ClinicalTrials.gov on June 20, 2008
Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Juvenile Rheumatoid Arthritis

Intervention: Enbrel (Drug); Placebo (Drug)

Phase: Phase 3

Status: Terminated

Sponsored by: Amgen

Official(s) and/or principal investigator(s):
MD, Study Director, Affiliation: Amgen

Summary

Rationale: etanercept inhibits the effects of tumor necrosis factor, which plays an important role in the progression of rheumatoid arthritis. A study of children with polyarticular course juvenile rheumatoid arthritis showed that Enbrel had efficacy and was generally well tolerated in children ages 4-17 who had moderately to severely active disease and who failed treatment with one or more disease modifying antiarthritic drugs. The children in the study may have had arthritis onset of pauciarticular, polyarticular, or systemic nature. Systemic onset juvenile rheumatoid arthritis (SOJRA) may result in approximately one-third of patients having significant long-term disability. Purpose: the Phase 4 study is designed to further define the safety and efficacy of etanercept in those children with SOJRA.

Clinical Details

Official title: Phase 3 Safety and Efficacy Study of Etanercept (Enbrel) In Children With Systemic Onset Juvenile Rheumatoid Arthritis

Study design: Treatment, Randomized, Double Blind (Subject, Investigator), Crossover Assignment, Safety/Efficacy Study

Primary outcome: Determine the efficacy of etanercept in pediatric subjects with systemically active systemic onset juvenile rheumatoid arthritis

Secondary outcome:

Determine the safety of etanercept in pediatric subjects with systemically active SOJRA

Determine the mean time to flare (up to 3 months) following withdrawal of etanercept in Part-2

Determine the safety and benefit of higher doses of etanercept (up to 0.8 mg/kg twice weekly) in Part-1B for children who have had a partial response to etanercept at 0.4 mg/kg twice weekly in Part-1A

Determine population pharmacokinetics for children with systemically active SOJRA at 0.4 mg/kg etanercept twice weekly and at 0.8 mg/kg twice weekly

Determine the effect on the cytokine profile in a substudy

Determine the time to response during open-label treatment with etanercept
