Clinical Trial Summary

Inhibitors of tumour necrosis factor (TNFa) reduce inflammation in patients with juvenile idiopathic arthritis (JIA), but only 20-40 percent achieve a state of no or very little disease activity. Tailored glucocorticoid joint injections are widely used (usually in general anaesthesia), but no controlled studies have addressed the effect of this approach. In Norway there are unique possibilities for early interventions, rapid escalation of medication and individualised therapy. The investigators aim to find the optimal ways to increase disease control and improve quality of life for JIA patients.

The hypothesis is that JIA patients starting TNF-inhibitors with added steroid injection of inflamed joints, will lead to improved outcomes compared to TNF-inhibitors with no joint injections, and that therapeutic drug monitoring, modern imaging and biologic and clinical profiling can be utilised to characterise JIA patients with different anti-TNF responses.

MyJIA is a national investigator initiated 48 weeks RCT of JIA patients starting TNF-inhibitors; 202 JIA patients will be randomised at baseline to A) concomitant intra-articular glucocorticoid injections versus B) no injections. Primary endpoint is the rate of sustained remission from weeks 24 to 36. Possible risk factors for not reaching remission will be analysed including clinical characteristics, drug antibodies/serum concentrations, patients' reported health status and preferences, molecular signalling (based on transcriptional, cellular and genetic risk) and synovitis detected by modern imaging (ultrasound and whole-body MRI).

Patients will be recruited from all Norwegian health regions through an established collaboration. Unit of Paediatric Rheumatology, Oslo University Hospital, with an extensive research track in this field, will be the coordinating centre. Broad research cooperation across disciplines is established. The trial is highly innovative in evaluating treatment options and strategies to individualise and optimise the efficacy and safety of JIA treatment.

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.

Exclusion Criteria:

Medical Conditions

1. Major comorbidity including uncontrolled infectious, neurological or mental disease, malignant disease, severe heart failure, severe renal failure, active ulcus ventriculi, and 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. Known hypersensitivity to Triamcinolone hexacetonide (Lederspan) or any of the excipients (sorbitol, polysorbate or benzyl alcohol).

5. Concomitant therapy with CYP3A-inhibitors or digitalis glycosides.

6. Known inherited fructose intolerance

7. Presence of hepatitis B surface antigen (HBsAg) at screening.

8. Positive hepatitis C antibody test result at screening or within 12 months prior to starting study treatment.

9. 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.

10. Having received live vaccines less than two weeks prior to randomisation.

11. Drug / alcohol abuse which hampers adherence to the study protocol.

12. Language barriers that hampers adherence to the study protocol.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The proportion of JIA participants with sustained inactive disease	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: a joint with swelling not due to bony enlargement OR, if no swelling is present; limitation of motion accompanied by either pain on motion and/or tenderness.	Week 24 to week 36.
Secondary	The proportion of participants with ACR pedi 30% response	American College of Rheumatology (ACR) paediatric 30% response (30% improvement in a minimum of 3 of any 6 variables in the paediatric core set criteria with no more than one of the remaining variables worsening more than 30%).; Pediatric core set criteria: Physician's global assessment of disease activity (visual analogue scale (VAS), range 0-100 where 0 represents best possible outcome).; Patient's/parent's global assessment of overall well-being (VAS, range from 0-100 where 0 represents best possible outcome); Functional ability (Childhood Health Assessment Questionnaire, CHAQ, lower scores are indicative of better functioning); Number of joints with active arthritis (range 0-71 where 0 represents best possible outcome); Number of joints with limited range of movement (range 0-70 where 0 represents best possible outcome); Erythrocyte sedimentation rate (normalised to a 0-10 scale where 0 represents best possible outcome)	Baseline to week 6,12 and 24
