Teens with diabetes test smart insulin pumps against surprise breakfasts

NCT ID NCT07455643

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This pilot study tested two automated insulin delivery systems (Medtronic 780G and Tandem t:slim X2) in 20 adolescents with type 1 diabetes. Participants ate breakfasts without telling the device how many carbs they were eating. The goal was to see how well each system controlled blood sugar after these unannounced meals. Results will help improve future closed-loop algorithms to reduce the need for manual insulin dosing.

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 (Medtronic 780G and Tandem t:slim X2 with Control-IQ)

What this could lead to

If successful, this study could help refine closed-loop algorithms to better manage unannounced meals, reducing the burden on teens with type 1 diabetes.

What could go wrong

This is a small pilot study with only 20 participants, so results may not apply to everyone. The findings are preliminary and need confirmation in larger trials.
