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 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.
