New pump insulin could speed up blood sugar control for type 1 diabetes
NCT ID NCT06809621
First seen Jun 26, 2026 · Last updated Sep 11, 2026 · Updated 2 times
Summary
This completed Phase 1 study tested a new fast-acting insulin called NNC0471-0119 in 43 adults with type 1 diabetes who use an insulin pump. The goal was to see how quickly the insulin enters the bloodstream, how long it works, and how safe it is compared to a standard insulin (insulin aspart). Each participant received both insulins at separate visits. The study lasted about 1-3 months and measured blood sugar-lowering effects and safety.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- NNC0471-0119 (a fast-acting insulin)
- What this could lead to
- If successful, this could lead to a faster-acting insulin for insulin pumps, helping people with type 1 diabetes manage blood sugar more effectively after meals.
- What could go wrong
- This is a small, early-phase study (Phase 1) focused on safety and how the drug works in the body. It may not show better results than existing insulins, and further larger trials are needed.
