New drug aims to tame rare artery disease
NCT ID NCT04161898
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.
