Plain English Summary

Background and study aims
The aim of this study is to compare two different steroid treatments in children and young people with new-onset polyarticular juvenile idiopathic arthritis (JIA) to find out which is best. Medications used in the long-term management of JIA take around 12 weeks to start working. Steroids act quickly, reducing inflammation whilst the other medications start to work but have many potential side effects. There is a lack of evidence to suggest whether intravenous steroids or oral steroids are more effective, safe, tolerable for patients and which have a greater impact on quality of life.

Who can participate?
Patients aged 1-18 years of age with at least five inflamed joints and newly diagnosed polyarticular JIA

What does the study involve?
They will be randomly allocated to either a 6-week course (reducing dose regimen) of prednisolone liquid or tablets, taken at home OR a 3-day course of intravenous methylprednisolone on a hospital day-case unit. Participants will be assessed before starting treatment (baseline) and four follow-up visits at 6, 12, 24 and 52 weeks, in line with standard care appointments. Study visits will include assessments in standard care however, additional study-specific assessments will include reporting of side effects, and steroid toxicity risk including extra blood tests, questionnaires relating to the impact of JIA and treatment on quality of life and cost. The study offers an option for participants to donate blood samples for storage in a biobank for future research. Samples will not be analysed as part of the study but adopted by Liverpool University Biobank.

What are the possible benefits and risks of participating?
The direct burden on participation will be minimal as all research visits have been scheduled at the same time as standard-of-care visits to minimise the burden to participants. Research blood samples are taken at the same time as standard-of-care bloods to reduce burden.
Participants will be asked to complete several questionnaires which will prolong their clinic appointments. Once complete the questionnaire will be handed to the research team.
Risks associated with being treated with steroids (the IMP and the comparator) via different routes for JIA with the IMP, These risks are stated in the trial information sheets and site teams are appropriately trained as both routes of administration are used as standard of care.
All of the above risks are minimized with appropriate training and following policies and procedures by hospital Trusts and as stated in the protocol. For participants receiving oral prednisolone from hospital pharmacies, the pharmacy will dispense the drug as prescribed with appropriate guidance for taking it. For participants receiving IV methylprednisolone over 3 days on a hospital day unit, nurses who normally work on the day unit and have been appropriately trained to give IV methylprednisolone will be responsible for administering the drug and monitoring participants. It will not be given by Research Nurses who may be less familiar with the administration of this drug and do not usually administer this drug. This will minimize the risk of drug preparation, administration and monitoring errors.

Scientific titleSteroid Treatment Trial in JIA (STAR-JIA): A randomised trial to compare the effectiveness, safety and cost-effectiveness of intravenous versus oral corticosteroid induction regimens for children and young people with juvenile idiopathic arthritis
Study acronymSTAR-JIA
Study hypothesisPrimary objectives:
To compare the clinical effectiveness of intravenous methylprednisolone versus oral prednisolone for controlling new-onset polyarticular juvenile idiopathic arthritis (JIA) in JIA Core Outcomes.

Secondary objectives:
1. To compare the differences in JIA Core Outcomes for intravenous methylprednisolone versus oral prednisolone for the following domains:
1.1. Pain
1.2. Function
1.3. Health-related Quality of Life (HRQOL)
2. To assess the effectiveness of intravenous versus oral corticosteroids in minimising the need for additional treatments including all corticosteroid routes and additional disease-modifying anti-rheumatic drugs (DMARDs)/biologics.
3. To evaluate short/medium-term safety and tolerability of IV versus oral corticosteroids, with regards to adverse reactions, serious adverse events, laboratory assessments and paediatric glucocorticoid toxicity index (pGTI).
4. To determine if a dose-response relationship can be identified in the efficacy/adverse responses to corticosteroids across all participants by secondary analysis, normalising corticosteroids received for dose, bioavailability and potency using previously published data.
