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.
(SELECT-sJIA)
What this study is about
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.
View original scientific description
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.
Interventions
DRUG
Upadacitinib
Oral tablet or Oral solution
DRUG
Tocilizumab
Subcutaneous injection or Intravenous infusion
Primary outcome measures
Percentage of Participants Achieving Adapted systemic Juvenile Idiopathic Arthritis (sJIA) American College of Rheumatology (ACR) 30 Response
Time frame: At Week 12
ACR criteria measure improvements in tender and swollen joint counts, patient assessments of pain, global disease activity and physical function, physician global assessment of disease activity and acute phase reactant. ACR 30 Response is defined as absence of fever \[\> 38°C\] in the previous 1 week preceding evaluation and improvement of ≥ 30% of the 6 variables of the JIA core set with no more than 1 variable worsening by \> 30%.
Number of Participants with Adverse Events (AEs)
Time frame: Up to Approximately Week 52
An AE is defined as any untoward medical occurrence in a patient or clinical investigation in which a participant is administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria

- Must have active sJIA with at least 2 active joints at Screening and Baseline, fever more than 38°C on at least one day within 14 consecutive days before the Screening Visit, and an erythrocyte sedimentation rate (ESR) or high-sensitivity C-reactive protein (hsCRP) \> upper limit of normal (ULN) at Screening. OR At least 4 active joints at Screening and Baseline and an ESR or hsCRP \> ULN at Screening.
- Must have inadequate response to previous treatment with nonsteroidal anti-inflammatory drugs and/or systemic glucocorticoids, as judged by the investigator.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
