Abstract
- Objectives: CLIPPER2 was an 8-year, open-label extension of the phase 3b, 2-year CLIPPER study on the safety and efficacy of etanercept in patients with JIA, categorized as extended oligoarticular arthritis (eoJIA), enthesitis-related arthritis (ERA) or PsA.<br />Methods: Participants with eoJIA (2-17 years old), ERA or PsA (each 12-17 years old) who received ≥1 etanercept dose (0.8 mg/kg weekly; maximum 50 mg) in CLIPPER could enter CLIPPER2. Primary end point was occurrence of malignancy. Efficacy assessments included proportions achieving JIA ACR 30/50/70/90/100 criteria and ACR inactive disease criteria, and clinical remission (ACR criteria) or Juvenile Arthritis DAS (JADAS) ≤1.<br />Results: Overall, 109/127 (86%) CLIPPER participants entered CLIPPER2 [n = 55 eoJIA, n = 31 ERA, n = 23 PsA; 99 (78%) on active treatment]; 84 (66%) completed 120 months' follow-up [32 (25%) on active treatment]. One malignancy (Hodgkin's disease in 18-year-old patient with eoJIA treated with methotrexate for 8 years) was reported; there were no cases of active tuberculosis or deaths. Numbers and incidence rates (events per 100 patient-years) of TEAEs (excluding infections/ISRs) decreased from 193 (173.81) in Year 1 to 9 (27.15) in Year 10; TE infections and serious infections also decreased. Over 45% of participants (n = 127) achieved JIA ACR50 responses from Month 2 onwards; 42 (33%) and 34 (27%) participants achieved JADAS and ACR clinical remission, respectively.<br />Conclusions: Etanercept treatment up to 10 years was well tolerated, consistent with the known safety profile, with durable response in the participants still on active treatment. The benefit-risk assessment of etanercept in these JIA categories remains favourable.<br />Trial Registration: ClinicalTrials.gov IDs: CLIPPER (NCT00962741); CLIPPER2 (NCT01421069).<br /> (© The Author(s) 2023.
