NCT06654882 | NOT YET RECRUITING | Polyarticular Course Juvenile Idiopathic Arthritis (JIA)

Trial of Sequential Medications AfteR TNFi Failure in Juvenile Idiopathic Arthritis
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 randomization addresses whether each of the 3 non-TNFi medications is superior to treatment with a second TNFi. The second randomization allows identification of optimal sequential use of biologics (treatment strategies).

Condition or disease

Polyarticular Course Juvenile Idiopathic Arthritis (JIA)

Intervention/treatment

TNFi (Tumor Necrosis Factor inhibitor) medication

Abatacept

Tocilizumab

Tofacitinib

PHASE3

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 inadequate response to initial TNFi. Leveraging sequential multiple assignment randomized trial (SMART) design methodology, we will implement a second randomization to assess the effectiveness of changing medication if there is inadequate response to the first study medication. This approach allows identification of optimal strategies for medication sequencing based on individual characteristics and provides critical insights to inform future studies. SMART-JIA will study the efficacy of a second TNFi (active control) compared to each of 3 other already US Food and Drug Administration (FDA)-approved and European Union (EU)-approved non-TNFi medications currently used to treat pcJIA (IL-6i, JAKi, and ABA). TNFi, IL-6i, and ABA are administered by subcutaneous (SQ) injection weekly, or every other week, or every three weeks, and JAKi (e.g., tofacitinib) is taken orally twice daily. All study treatments have similar safety profiles and are standard of care (SOC) worldwide. This in addition to the pragmatic and full-scale nature of the trial will ensure its completion. Successful completion of this trial will substantially impact the clinical care and outcomes of children with pcJIA, shifting the current trial-and-error treatment paradigm to a smart, precise approach.
