New siRNA drug aims to tame kidney disease
NCT ID NCT06989359
First seen Jun 24, 2026 · Last updated Sep 04, 2026 · Updated 6 times
Summary
This Phase 2 study is testing a new drug called ADX-038 in 45 adults with complement-mediated kidney diseases, such as IgA nephropathy and C3G. The drug is an siRNA that targets the complement system, which is overactive in these conditions. Researchers are checking if it is safe and can help control the disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ADX-038 (siRNA drug)
- What this could lead to
- If successful, this could lead to a new treatment option that helps control complement-mediated kidney diseases, potentially slowing disease progression and reducing symptoms.
- What could go wrong
- This is an early Phase 2 trial with only 45 participants, so results may not apply to everyone. The drug may not work as hoped or could cause side effects.
