Evaluating a new insulin delivery system for children with newly diagnosed type 1 diabetes

Assessing the Effect of Advanced Hybrid Closed Loop System, MiniMed 780G With GS4 Glucose Sensor in Newly Diagnosed Children and Adolescents With Type 1 Diabetes on Glycemic Control and Patient Reported Outcomes Compared to Standard Insulin Therapy Historical Data (AHCL in New Onset T1D Children Study): a Single Arm Open- Label Prospective Observational Study Protocol

Observational National and Kapodistrian University of Athens · NCT06919029

This study is testing a new insulin delivery system to see if it helps children and teens with newly diagnosed type 1 diabetes manage their blood sugar better than traditional methods.

What this trial studies

This study aims to assess the effectiveness of the Advanced Hybrid Closed Loop (AHCL) system MiniMed 780G in managing glycemic control in children and adolescents aged 7 to 17 who have recently been diagnosed with type 1 diabetes. Participants will use the AHCL system in conjunction with continuous glucose monitoring, and their outcomes will be compared to historical data from patients treated with multiple daily injections. The study will be conducted as a single-arm open-label observational study over a period of three months, with a potential three-month extension phase. The goal is to gather data on glycemic control and patient-reported outcomes.

Who should consider this trial

Good fit: Ideal candidates are children and adolescents aged 7 to 17 years who have been clinically diagnosed with type 1 diabetes.

Not a fit: Patients with type 2 diabetes, untreated comorbidities, or those on medications affecting metabolic control may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved glycemic control and quality of life for children and adolescents with newly diagnosed type 1 diabetes.

How similar studies have performed: Other studies have shown promising results with advanced hybrid closed loop systems in diabetes management, suggesting potential for success in this approach.
