First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compared two common diabetes drugs—dapagliflozin and metformin—in over 2,000 people with early type 2 diabetes (diagnosed less than 4 years). The goal was to see which drug better prevents serious complications like death, heart attack, stroke, heart failure, kidney disease, eye problems, and foot ulcers. Participants took either dapagliflozin or metformin, and researchers tracked their health using national registries.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- dapagliflozin (a drug that lowers blood sugar by helping the kidneys remove sugar through urine)
- What this could lead to
- If dapagliflozin works better than metformin, it could become a preferred first treatment for early type 2 diabetes to reduce the risk of serious complications like heart attack, stroke, and kidney disease.
- What could go wrong
- This is a completed Phase 4 trial, but it is open-label (patients and doctors know the treatment), which can bias results. Also, the benefit may be small or not apply to all patients with early diabetes.
