Weekly combo shot shows promise for diabetes control
NCT ID NCT05813912
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed Phase 3 study tested whether adding semaglutide to a new once-weekly insulin (insulin icodec) improves blood sugar control in 148 adults with type 2 diabetes. Participants first received insulin icodec alone for 26 weeks; those with still-high blood sugar then added semaglutide for another 26 weeks. The main goal was to see how much HbA1c (a measure of blood sugar over time) changed after adding semaglutide.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- semaglutide and insulin icodec
- What this could lead to
- If successful, this combination could offer a more effective once-weekly treatment option for people with type 2 diabetes who need better blood sugar control.
- What could go wrong
- This is a single-arm study with no comparison group, so results may not prove superiority over existing treatments. Side effects like nausea or low blood sugar are possible.
