Summary

This phase 3 trial tests whether upadacitinib (Rinvoq) can help people with Takayasu arteritis, a rare disease that inflames large arteries. About 56 adults who have had a recent relapse despite steroids will receive either upadacitinib or a placebo, along with a steroid taper. The main goal is to see if the drug delays or prevents another relapse.

What this could mean

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

Active substance
upadacitinib (Rinvoq)
What this could lead to
If successful, this could offer a new treatment option to control Takayasu arteritis and reduce reliance on steroids.
What could go wrong
This is a relatively small phase 3 trial, and the drug may not prevent relapses better than placebo. Upadacitinib also carries risks like infections and allergic reactions.
