The Pediatric Artificial Pancreas Automated Initialization Trial (PEDAP-AI)
January 5, 2024 updated by: Marc Breton
The Pediatric Artificial Pancreas Automated Initialization Trial (PEDAP-AI): A Pilot Study of AI Advisor-Driven Pump Initiation and Parameter Adaptation in Young Children With Type 1 Diabetes
The goal of this clinical trial is to obtain safety data and exploratory glycemic control data from use of an at-home closed loop control (CLC) system (t:slim X2 with Control-IQ Technology) with periodic parameter adjustments driven by an AI-based Advisor system in young children with Type 1 Diabetes.
The main endpoints this study aims to answer is the safety and efficacy of the use of the AI-driven pump parameters.
Participants will use the study system (pump and Continuous Glucose Monitor) in closed-loop mode for eight weeks.

Detailed Description
In this single-arm pilot study of an AI Advisor-driven closed loop system initiation and parameter adaptation in youth age 2 to <6 years old, participants will use the Tandem t:slim X2 with Control-IQ and t:connect mobile application and Dexcom G6 or G7 system, connected to the University of Virginia (UVA) cloud-based Physician Dashboard for eight weeks at home.
The key safety outcomes are time spent below 54mg/dL and time spent above 250mg/dL compared with baseline and with a matched historical control population over the same time period from the prior PEDAP study that did not involve the use of any AI-driven pump parameters.
Severe hypoglycemia and diabetic ketoacidosis episodes will also be reported.
Glycemic outcomes including time in target range 70-180 mg/dL (TIR) and various other CGM measures of hypo- and hyperglycemia will be assessed and compared with baseline and the PEDAP historical control mentioned above.
Up to 45 screened participants with the goal of at least 30 participants completing the study pump use period.
