New drug aims to tame rare inflammatory disease

NCT ID NCT05263934

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 3 trial tests whether a new drug, depemokimab, works as well as the current treatment mepolizumab for adults with a rare disease called EGPA, which causes inflammation of blood vessels. The study involves 163 participants and aims to see if depemokimab can help patients achieve remission while reducing their steroid use. Results are expected after 52 weeks of treatment.

What this could mean

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

Active substance

depemokimab (compared to mepolizumab)

What this could lead to

If depemokimab works as well as mepolizumab, it could offer a new treatment option for EGPA, potentially with less frequent dosing.

What could go wrong

This is a non-inferiority trial, so depemokimab may not be better than the existing drug. Results are still pending, and individual responses may vary.
