E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Juvenile idiopathic arthritis is characterised by inflamed joints and is the most common chronic rheumatic disease in childhood and adolescence that potentially lead to disability due to joint damage. A prerequisite for the JIA diagnosis is the detection of inflammation of one or more joints (arthritis). Arthritis leads to pain, swelling and stiffness of the affected joints, caused by hypertrophy of the synovial lining of the joint and increased synovial fluid. Untreated, disability may follow. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess if concomitant intra-articular (i.a.) glucocorticoid injections of joints with active arthritis in juvenile idiopathic arthritis (JIA) patients starting Tumour Necrosis Factor (TNF) inhibitor (TNFi) treatment increase the proportion of JIA patients reaching sustained, inactive disease, when compared to the control group not receiving joint injections. |
|
E.2.2 | Secondary objectives of the trial |
- To compare efficacy of treatment regimens up to 24 weeks. - To assess the safety of the intervention and background treatment. - To compare the cost effectiveness of the two treatment regimens - To evaluate the longitudinal disease burden of JIA over 48 weeks - To explore the impact of TNFi concentrations - To explore molecular signatures - To explore the role of modern imaging techniques - To explore composite measures of JIA disease burden as predictor of treatment response. |

E.3 | Principal inclusion criteria |
Type of Participant and Disease Characteristics Participants are eligible to be included in the study only if all of the following criteria apply: 1. 1-18 years of age at the time of signing the informed consent. 2. Fulfilment of the International League of Associations for Rheumatology (ILAR) classification criteria for non-systemic JIA. 3. Clinical indication for starting TNFi treatment according to consensus between at least two physicians. 4. Naïve to TNFi or prior use of one TNFi (stopped at least 3 months before study inclusion and no previous TNFi treatment failure). 5. Juvenile Disease Activity Score (JADAS) >1 at baseline and at least one joint with active arthritis were joint injection is considered. 6. Willing to give written consent (participant ≥ 16, guardians if < 16 years of age, both participants and guardians if 16-18) and comply with the requirements of the study protocol.
Contraceptive use by men or women Male participants: No measures necessary. Female participants: Contraception Guidance for WOCBP see Appendix 4 (Section 10.4.2). Informed Consent 7. Capable of giving signed informed consent as described in Appendix 1, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.

|
E.4 | Principal exclusion criteria |
Participants are excluded from the study if any of the following criteria apply: Medical Conditions 1. Major comorbidity including significant infectious, neurological, malignant disease, mental disorders or uncontrolled diabetes mellitus. Prior/Concomitant Therapy 2. Used two or more TNFi. 3. Corticosteroid use (including i.a. injection) less than 4 weeks prior to randomisation. Other Exclusions 4. Presence of hepatitis B surface antigen (HBsAg) at screening. 5. Positive hepatitis C antibody test result at screening or within 3 months prior to starting study treatment. 6. Evidence of active or latent tuberculosis (TB) as documented by medical history and examination, chest X-rays (front), and TB testing. The choice of TB tests will be made by the investigator according to local licensing and standard of care. 7. Having received live vaccines less than two weeks prior to randomisation. 8. Drug / alcohol abuse which hampers adherence to the study protocol. 9. Language barriers that hampers adherence to the study protocol. 10. Pregnancy or breast-feeding.

E.5 End points |
E.5.1 | Primary end point(s) |
The proportion of participants with sustained, inactive disease from week 24 to week 36. Inactive disease is defined according the 2011 Wallace criteria: No active arthritis† Physician global assessment of disease activity score normal (0) Erythrocyte sedimentation rate (ESR) within normal range Morning stiffness ≤ 15 minutes No active uveitis No fever, rash, serositis, splenomegaly, or generalized lymphadenopathy attributable to JIA In addition, no use of any i.a. or p.o. corticosteroids from week 20 to week 36.
†Active arthritis according to the ACR definition: 1) a joint with swelling not due to bony enlargement OR, if no swelling is present 2) limitation of motion accompanied by either pain on motion and/or tenderness.
