Could a diabetes drug shield kidneys from autoimmune attack?

NCT ID NCT05946564

First seen Jul 01, 2026 · Last updated Jul 01, 2026

Summary

This trial investigates whether pioglitazone, a drug used for diabetes, can help protect the kidneys in people with ANCA-associated vasculitis—a rare autoimmune disease that causes inflammation of blood vessels, often damaging the kidneys. Participants receive either pioglitazone or a placebo for 6 months, alongside standard immunosuppressive therapy. The goal is to see if pioglitazone reduces protein in the urine and improves kidney function, potentially limiting long-term damage.

What this could mean

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

Active substance

pioglitazone

What this could lead to

If it works, pioglitazone could become a standard add-on therapy to protect kidney function and reduce long-term damage in ANCA vasculitis patients.

What could go wrong

This is a Phase 3 trial with 126 participants, so results may not apply to all patients. Pioglitazone has known risks like fluid retention and potential heart effects.
