New drug gemini tested for kidney disease safety
NCT ID NCT06863467
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study tested a single dose of the experimental drug Gemini in 40 adults with stage 3 or 4 chronic kidney disease. The main goal was to check safety and side effects compared to a placebo. Researchers also measured how the drug moves through the body and its effect on inflammation and kidney function markers.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Gemini (a phosphorylated hexaacylated disaccharide)
- What this could lead to
- If successful, this could point toward a new way to reduce inflammation and slow kidney damage in chronic kidney disease.
- What could go wrong
- This is a very early, small study focused on safety, not effectiveness. It may not show any benefit, and side effects are unknown.
