- NCT06654882
- Lead Sponsor
- Duke University
- Brief Summary
This study is an open-label, randomized, multicenter trial that incorporates a multi-arm design comparing each of 3 non-TNFi (Tumor Necrosis Factor inhibitor) medications to a second TNFi (active control) within a sequential multiple assignment randomized trial design with 2 randomization stages corresponding with clinical decision points. The first randomiz...
- Detailed Description
The goal of the study is to provide an evidence base for selecting sequential medication(s) if a JIA patient fails initial bDMARD. SMART-JIA is a pragmatic, international, open-label, randomized trial comparing treatment with a second TNFi (active control) to each of 3 different medications (IL-6i, JAKi, or ABA) in children aged 2 to 17 years with pcJIA and ...

Group Intervention Description Abatacept Abatacept The 50 mg, 87.5 mg and 125 mg SQ doses will be available for weight-based dosing. All participants randomized to abatacept in the first or second stage randomization will receive abatacept SQ weekly at a dosage based on the participant's body weight Second TNFi (Tumor Necrosis Factor inhibitor) medication TNFi (Tumor Necrosis Factor inhibitor) medication Adalimumab originator or biosimilar; etanercept originator or biosimilar depending on which TNFi the participant had failed. Tocilizumab originator or biosimilar Tocilizumab Tocilizumab will be provided in prefilled syringes (162 mg tocilizumab/0.9 mL solution). All participants randomized to tocilizumab in the first or second stage randomization will be receiving 1 prefilled syringe (162 mg) with a dosing interval based on the body weight criteria. Tofacitinib Tofacitinib Tofacitinib will be provided as oral tablets (tofacitinib citrate 5 mg) and as an oral solution (1 mg/mL). All participants randomized to tofacitinib in the first or second stage randomization will receive tofacitinib oral tablets or oral solution twice daily, approximately 12 hours apart, in the morning and evening, at a dosage based on the participant's body weight .
