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.
