A Study of Baricitinib (LY3009104) in Participants From 1 Year to Less Than 18 Years Old With Systemic Juvenile Idiopathic Arthritis (sJIA)

February 9, 2026 updated by: Eli Lilly and Company

Open-Label, Randomized Study With a Tocilizumab Reference Arm to Evaluate Safety, Efficacy and Pharmacokinetics of Baricitinib in Children From 1 to Less Than 18 Years of Age With Systemic Juvenile Idiopathic Arthritis.

The reason for this study is to see if the study drug baricitinib is safe and effective in participants from 1 year to less than 18 years old with systemic juvenile idiopathic arthritis (sJIA). Participants are assigned to 1 of 2 cohorts. In cohort 1, participants will receive baricitinib or tocilizumab reference. In cohort 2, participants will receive baricitinib.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 year to 17 years (Child)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Participants must have a diagnosis of systemic Juvenile Idiopathic Arthritis (sJIA) as defined by International League of Associations for Rheumatology (ILAR) criteria with onset before the age of 16 years
  • Participants must have at least 2 active joints at screening and baseline
  • Cohort 1 (IL-6 inhibitor therapy naive): Participants who are at least 1 year and less than 18 years of age, except in countries that restrict use of tocilizumab in participants less than 2 years of age
  • Cohort 2 (open-label baricitinib): Participants who are at least 1 year and less than 18 years of age

Exclusion Criteria:

  • Participants must not have polyarticular JIA (positive or negative for rheumatoid factor), extended oligoarticular JIA, enthesitis-related JIA, or juvenile psoriatic arthritis
  • Participants must not have persistent oligoarticular arthritis as defined by the ILAR criteria
  • Participants must not have a history or presence of any autoimmune inflammatory condition other than JIA
  • Participants must not have active anterior uveitis or are receiving concurrent treatment for anterior uveitis
  • Participants must not have active fibromyalgia or other chronic pain conditions that, in the investigator's opinion, would make it difficult to appropriately assess disease activity for the purposes of this study
  • Participants must not have biologic features of Macrophage Activation Syndrome (MAS) over the past 12 weeks
  • Participants must not have a current or recent (<4 weeks prior to baseline) clinically serious infection
  • Participants must not have a positive test for hepatitis B virus
  • Participants must not have evidence of active tuberculosis (TB) or untreated latent TB

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
February 12, 2020

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
September 1, 2026

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
