A smarter insulin that aims for the liver could curb dangerous nighttime dips
NCT ID NCT06238778
First seen Jul 31, 2026 · Last updated Jul 31, 2026
Summary
This trial tests whether a specially designed mealtime insulin, HDV-insulin lispro, can reduce nighttime low blood sugar (hypoglycemia) in adults with type 1 diabetes. Participants will use continuous glucose monitors and work with doctors to adjust doses. One group receives the liver-targeted insulin, while the other uses standard insulin lispro. The study lasts up to 32 weeks and also tracks blood fats and liver enzymes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- HDV-Insulin lispro, a liver-targeted form of mealtime insulin
- What this could lead to
- If successful, this approach could reduce dangerous nighttime low blood sugar episodes in people with type 1 diabetes, improving safety and quality of life.
- What could go wrong
- This is an early-phase trial, so results may not hold up in larger studies. The liver-targeting insulin may not perform better than standard insulin and could have unexpected side effects.
