Abstract

Background: CLIPPER2 was an 8-year, open-label extension of the phase 3b, 2-year CLIPPER study of the safety and efficacy of etanercept (ETN) in patients (pts) with juvenile idiopathic arthritis (JIA), categorized as extended oligoarticular JIA (eoJIA), enthesitis-related arthritis (ERA), or psoriatic arthritis (PsA). Objectives: Evaluation of the efficacy of ETN and its effect on health outcomes over 10 years of follow-up were secondary objectives and are reported here. Methods: Pts (n=127) with eoJIA (n=60; 2-17 years of age), ERA (n=38; 12-17), or PsA (n=29; 12-17) who received ≥1 ETN dose (0.8 mg/kg once weekly [max, 50 mg]) in CLIPPER were eligible to enter CLIPPER2. The study design has been reported previously.1 Efficacy endpoints included proportions of pts achieving JIA American College of Rheumatology (ACR) 30/50/70/90/100 criteria, Juvenile Arthritis Disease Activity Score (JADAS) inactive disease and clinical remission criteria, and sustained clinical remission (ACR criteria) or JADAS ≤1 for 12 continuous months (mths). Exploratory efficacy endpoints included time to fare following ETN withdrawal (based on ≥30% worsening in ≥3/6 ACR Pedi components, with ≥30% improvement in
