Summary

This Phase 3 trial tests whether adding avacopan to standard treatment helps people with severe ANCA vasculitis and serious kidney damage. About 130 participants will receive either avacopan or a placebo alongside usual care. The goal is to see if more patients recover kidney function and need fewer steroids.

What this could mean

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

Active substance

Avacopan

What this could lead to

If successful, adding avacopan to standard therapy could improve kidney recovery and reduce the need for high-dose steroids in severe ANCA vasculitis.

What could go wrong

This is a Phase 3 trial, but it's still early for this specific severe group. Avacopan may not improve outcomes enough, and side effects or infections remain possible.
