The objective of this study is to evaluate glycemic control of users of the AHCL system MiniMed 780G with GS4 calibration-free sensor in children and adolescents with newly diagnosed T1D implemented directly upon T1D diagnosis in combination with continuous glucose monitoring system (CGMS) compared with those treated with MDI retrieved from historical data- in a single- arm open-label prospective observational study, assessed at 3 months. After the initial study period there will be a 3month extension phase of the study.
