Can Open-Source insulin systems match commercial ones without meal announcements?
NCT ID NCT07758647
First seen Aug 11, 2026 · Last updated Aug 12, 2026 · Updated 1 time
Summary
This trial tests whether open-source automated insulin delivery (AID) systems can control blood sugar as well as commercial systems in adults with type 1 diabetes, even when meals are not announced. Participants will use both types of systems for four weeks each, with a focus on glucose levels after unannounced meals. The goal is to see if open-source systems can reduce the burden of carbohydrate counting while maintaining good glucose control.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Automated insulin delivery systems (open-source and commercial)
- What this could lead to
- If open-source systems match commercial ones, people with type 1 diabetes may have more flexible, less burdensome options for managing blood sugar without meal announcements.
- What could go wrong
- This is a small crossover trial, and results may not apply to everyone. Unannounced meals could lead to high blood sugar, and the study doesn't test long-term outcomes.
