New hope for kids with stubborn kawasaki disease: drug targets fever and heart risks

NCT ID NCT01596335

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested a drug called TA-650 in 31 children with Kawasaki disease whose fever did not go away after standard IVIG treatment. The goal was to see if TA-650 could bring down the fever faster and prevent damage to heart arteries compared to another immunoglobulin treatment. The drug was given as a single IV infusion, and researchers also checked how the body processes it.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
TA-650 (a drug given by IV infusion)
What this could lead to
If it works, this could offer a new treatment option for children with Kawasaki disease who don't respond to standard therapy, potentially reducing fever and preventing heart complications.
What could go wrong
This is a small, completed phase 3 trial with only 31 participants, so results may not apply to all patients. The drug may not be more effective than the control treatment, and side effects are possible.
