Overview of the trial program
The trial data show three interventional studies of Triamcinolone Hexacetonide in different patient groups.[1][2][3] The studies focus on juvenile idiopathic arthritis, carpal tunnel syndrome, and rheumatoid arthritis.[1][2][3] Two trials are authorised and one is completed.[1][2][3]
Juvenile idiopathic arthritis study
NCT04614311, called The My-JIA trial, is a Phase 3 study in children and young people with juvenile idiopathic arthritis.[1] It enrolled 188 participants and is completed.[1] The study asks whether adding intra-articular glucocorticoid injections, meaning steroid injections into the joint, to TNF inhibitor treatment helps more patients reach sustained inactive disease.[1]
The main endpoint is the proportion of participants with sustained inactive disease according to the Wallace 2011 criteria and no intra-articular or oral glucocorticoid use from week 24 to week 36.[1] In simple terms, the trial checks whether joint injections help children stay well for a longer time without needing more steroid treatment.[1]
Carpal tunnel syndrome study
NCT05306548, called NOR-CACTUS, is a Phase 3 study in people with carpal tunnel syndrome.[2] It is authorised and plans to include 258 participants.[2] The study compares an injection-based strategy with ultrasound-guided injections, up to two injections, scheduled follow-up visits, and surgery if needed, against a strategy where surgery is the main treatment.[2]
The primary outcome is successful treatment after one year, defined as a Boston Carpal Tunnel Questionnaire Symptom Score of 1.5 or lower.[2] This means the study is testing whether starting with injections can work as well as surgery for improving symptoms over 12 months.[2]
Rheumatoid arthritis study
NCT01491815 is a multicenter, randomized, open-label, blinded-assessor Phase 3 study in early rheumatoid arthritis.[3] It is authorised and has an enrollment of 705 participants.[3] The study compares active conventional therapy with three biologic treatments and also looks at two de-escalation strategies in people who respond to treatment.[3]
De-escalation means reducing treatment after a person has responded well.[3] Triamcinolone Hexacetonide appears in the treatment list as an intra-articular injection option in this study.[3] The study is designed to see how many patients reach remission and how joint damage changes over time.[3]
Main endpoints and outcome measures
Across the three studies, the main outcomes focus on disease control and treatment success.[1][2][3] In juvenile idiopathic arthritis, the endpoint is sustained inactive disease without extra steroid use between weeks 24 and 36.[1] In carpal tunnel syndrome, the endpoint is symptom score improvement at one year.[2] In rheumatoid arthritis, the endpoints include remission at week 24 and progression of the Sharp van der Heijde score at 48 weeks, which tracks joint damage on X-ray.[3]
Trial design, phases, and participants
All three studies are interventional trials, which means the researchers assign treatments and then measure what happens.[1][2][3] The data include Phase 3 studies for juvenile idiopathic arthritis, carpal tunnel syndrome, and rheumatoid arthritis, plus one Phase 4 study in early rheumatoid arthritis.[1][2][3] The target populations are children or young people with juvenile idiopathic arthritis, adults with carpal tunnel syndrome, and people with early rheumatoid arthritis.[1][2][3]
