NCT ID NCT05083182
First seen Jun 25, 2026 · Last updated Jul 31, 2026 · Updated 2 times
Summary
This study is testing two injectable drugs, ustekinumab and guselkumab, in 50 children with active juvenile psoriatic arthritis. The goal is to see how well the drugs work, how they move through the body, and if they are safe. Participants will receive one of the drugs and be monitored for about a year.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ustekinumab and guselkumab (biologic drugs given as injections)
- What this could lead to
- If successful, this study could show that these drugs are safe and effective for children with juvenile psoriatic arthritis, offering a new treatment option.
- What could go wrong
- This is an early-phase study with only 50 children, so results may not apply to everyone. The drugs can have side effects like increased risk of infections.
