The Loop Observational Study — LOS  

Diabetes Mellitus, Type 1 Clinical Trial

Official title:
An Observational Study of Individuals With Type 1 Diabetes Using the Loop System for Automated Insulin Delivery

Clinical Trial Summary

An observational study to collect data on the efficacy, safety, usability, and quality of life/psychosocial effects of the Loop DIY automated insulin delivery system.

Clinical Trial Description

The study will include both adults and youth in the United States, with a recruitment goal of at least 300-1,250 participants. Data to be collected to address the study objective will include CGM metrics; HbA1c; insulin delivery data; carbohydrate data; activity data from HealthKit; self-reported adverse events (e.g., severe hypoglycemia, diabetic ketoacidosis, hospitalizations); self-reported device issues; and psychosocial and user experience/treatment satisfaction surveys.

Online forms will allow participants to report weekly device issues and serious adverse events including severe hypoglycemia, diabetic ketoacidosis, and hospitalizations. General data updates will be obtained after three, six, and 12 months (and every six months thereafter if study participation continues). A fingerstick blood sample will be collected for HbA1c measurement after three months for cohort A and after six and 12 months for both cohorts. Quality-of-life/psychosocial and treatment satisfaction questionnaires will be completed after six and 12 months; new users also will complete questionnaires after 3 months. Virtual focus groups will be completed within the first three months of starting Loop and at 12 months. ;
