Clinical trial for IgA Nephropathy (IgAN)
Official title Avacopan in Crescentic Immunoglobulin A Nephropathy (IgAN)
ClinicalTrials.gov ID: NCT06676579
What this study is testing
What is Avacopan?
This is an investigational oral medicine being studied as a potential treatment for a serious kidney condition called IgA Nephropathy. It is designed to block a specific protein in the immune system that can cause inflammation in the kidneys.
Also referred to as Tavneos.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study is testing whether Avacopan with low‑dose steroids can improve kidney health and safety in people with high‑risk IgA nephropathy.
- Who it's for
- You may be able to join if you have severe IgA kidney disease that is likely to get worse.
- What's involved
- You will receive Avacopan and a small amount of steroids, and you will have regular check‑ups and tests to see how you are doing.
- Time commitment
- The study lasts several months and includes multiple visits to the clinic for monitoring.
- Phase 2: a mid-size study of how well it works
- Which group you join is decided by chance.
