ClinConnect Summary

This clinical trial is studying a smartphone app called PACTAID, designed to help adults with type 1 diabetes manage their exercise routines while using automated insulin delivery systems. The goal is to see if this app can improve blood sugar control during and after exercise, as well as support heart health. The trial is currently recruiting participants aged 18 to 65 who have been diagnosed with type 1 diabetes and are using specific insulin delivery devices for at least three months. To participate, individuals must also have good blood sugar levels and be willing to complete the study procedures.

Participants in this trial can expect to use the PACTAID app while engaging in different types of exercises. They will need to have regular check-ins to monitor their blood sugar and overall health. It’s important to note that certain health conditions could exclude someone from joining, such as severe heart issues or uncontrolled diabetes. If you or someone you know is interested, it's a great opportunity to potentially improve diabetes management with the support of a new technology.
