The sponsor has requested to end the study prematurely due to the accumulation of delays caused by COVID-19 as potential participants were hesitant to allow staff members into their homes or stay at the hospital per the study design.

The objective of this clinical trial is to assess the safety of our insulin dosing algorithm in children with type 1 diabetes in a free-living study.
This is a preliminary pilot study to generate data to optimize an insulin dosing algorithm to regulate glucose levels in children with type 1 diabetes. There will be up to two 40-hour test in outpatient settings, in which we will assess an insulin dosing algorithm. The two tests will allow us to compare different tunings in the same patient (this allows easier interpretation of the data). For example, if in a specific participant, the dosing algorithm reduced insulin delivery at night to avoid low blood glucose levesl but led to a rebound increase in glucose levels, then a second visit with a slightly different target range will help answer this question. The objective of this clinical trial is to assess the safety of our algorithm in children with type 1 diabetes in a free-living study.

The pilot study aims to enroll 20 children participants with type 1 diabetes mellitus using insulin pump therapy. Each participant will undergo a 40-hour intervention period, with the possibility of being invited to a second 40-hour intervention period using the same system.
