New automated insulin system tested in tiny trial
NCT ID NCT05299177
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested a system that automatically adjusts insulin delivery using a continuous glucose monitor, a smartphone app, and an insulin pump. It aimed to see if the system could help adults with type 1 diabetes spend more time with their blood sugar in a healthy range. Only one person took part, and the trial was stopped early, so the results are very limited.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- InControl automated insulin delivery system (smartphone app, continuous glucose monitor, and insulin pump)
- What this could lead to
- If successful, this could help people with type 1 diabetes manage their blood sugar more easily with less effort.
- What could go wrong
- This was a very small feasibility study with only 1 participant, so results may not apply to others. The trial was terminated early, so data is limited.
