Study of Oral Upadacitinib and Subcutaneous/Intravenous Tocilizumab to Evaluate Change in Disease Activity, Adverse Events and How Drug Moves Through the Body of Pediatric and Adolescent Participants With Active Systemic Juvenile Idiopathic Arthritis.

Study Purpose

Juvenile Idiopathic Arthritis (JIA) is the most common type of arthritis that affects children. The term "idiopathic" means "of unknown origin". It is a chronic (long-lasting) disease that causes swelling, warmth, and pain of one or more small joints. Systemic JIA ia a rare and serious form of JIA. Systemic" means it may affect not only the joints but other parts of the body, including the liver, lungs and heart. sJIA is more severe and can be more challenging to diagnose and treat than other types of juvenile idiopathic arthritis. It is a lifelong disease for many patients and can continue into adulthood. This study will assess how safe and effective upadacitinib is in treating pediatric and adolescent participants aged 1 to < 18 with systemic juvenile idiopathic arthritis (sJIA) and will include a tocilizumab treatment arm for reference. Adverse events and change in the disease activity will be assessed. Upadacitinib is an investigational drug being developed for the treatment of sJIA. Participants are assigned to 1 of 2 cohorts. In cohort 1, participants will receive upadacitinib or tocilizumab reference. In cohort 2, participants will receive upadacitinib. Approximately 90 participants with sJIA will be enrolled in approximately 45 sites worldwide. Participants will receive upadacitinib oral tablets once daily or oral solution twice daily or tocilizumab subcutaneous injection or intravenous infusion as per local label for 52 weeks and followed for approximately 30 days. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits/calls during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, checking for side effects and completing questionnaires.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	1 Year - 17 Years
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Baseline with a total body weight of 10 kg or higher at screening and a diagnosis of systemic juvenile idiopathic arthritis (sJIA) according to International League of Associations for Rheumatology (ILAR) criteria for at least 6 weeks prior to Screening, with onset prior to 16 years old, and meet the following conditions: - Must have active sJIA with at least 2 active joints at Screening and Baseline, fever more than 38°C for any out of 14 consecutive days before the Screening Visit, and an erythrocyte sedimentation rate (ESR) or high-sensitivity C-reactive protein (hsCRP) > 1.5 × upper limit of normal (ULN) at Screening.

OR At least 5 active joints at Screening and Baseline and an ESR or hsCRP > 1.5 × ULN at Screening.

- Must have inadequate response to previous treatment with nonsteroidal anti-inflammatory drugs and systemic glucocorticoids, as judged by the investigator.

- For Cohort 1, participants must not have had previous treatment with any IL-6 inhibitor.

For Cohort 2, participants must have an intolerance or inadequate response to an IL-6 inhibitor as judged by the investigator. Note: For Cohort 1, participants must be ages 2 to < 18 years old in countries where SC tocilizumab is not approved for sJIA.

Exclusion Criteria:

- Must have any type of juvenile idiopathic arthritis (JIA), other than sJIA, as defined by the ILAR criteria, and must not have a history or presence of any other autoimmune inflammatory condition other than sJIA.

- Must have uncontrolled severe systemic disease and/or impeding or active macrophage activation syndrome within 3 months prior to Baseline.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT05609630
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 3
