Diabetes kidney drug shows promise in slowing damage
NCT ID NCT03436693
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether canagliflozin, a diabetes drug, can slow kidney decline in 308 Japanese patients with diabetic nephropathy. Participants took either the drug or a placebo daily for about two years. The main goal was to see if fewer people on the drug had a 30% drop in kidney function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- canagliflozin
- What this could lead to
- If successful, this could provide a new option to slow kidney damage in people with diabetes-related kidney disease.
- What could go wrong
- This is a completed Phase 3 trial in Japanese patients only, so results may not apply to other populations. The drug may not significantly slow kidney decline compared to placebo.
