New weekly insulin shot could simplify diabetes care
NCT ID NCT04770532
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new insulin called icodec that is injected just once a week, compared to a standard daily insulin (degludec), in 526 adults with type 2 diabetes. The goal was to see if the weekly insulin controls blood sugar as well as the daily one over 26 weeks. Participants wore a continuous glucose monitor for part of the study and had regular blood tests.
