Efficacy of Automated Insulin Therapy Early Initiated After Diagnosis on Blood Glucose Control in Children and Adolescents With Type 1 Diabetes
The main objective is to assess whether hybrid closed-loop (HCL) insulin delivery initiated early after diagnosis of Type 1 diabetes (T1D) allows a better efficacy on glucose control than conventional standard insulin therapy with multiple daily insulin injections (MDI) or insulin pumps after one year of use.

The secondary objectives are to assess whether HCL initiated early after diagnosis of T1D allows: (1) Higher time spent with glucose level in the near-normal range, (2) Lower time spent in hypoglycemia and hyperglycemia, (3) Lower glucose variability, (4) Lower perceived burden of diabetes management, (5) Better preserved endogenous insulin secretion, all the above after one year of use, (6) Lower occurrence of interventions for hypoglycemia, versus conventional standard insulin therapy with MDI or insulin pump.

An optional 1-year extension aims at assessing: (1) Sustainability of above mentioned parameters over a second year of HCL use in the group who started HCL early after diagnosis, (2) Efficacy on glucose control according to the above mentioned parameters when HCL is initiated early after diagnosis vs. after 1 year in the control group of the randomized phase.
