|---|---|
| Main Objective: To determine the difference in Dried Blood Spots (DBS) fasted C-peptide between treatment and placebo groups at 48 weeks for the best dose/regimen of IMCY-0098 defined in the first step.;Secondary Objective: (1) To determine the changes in stimulated C-peptide response during the first two hours of a mixed meal tolerance test (MMTT) at baseline and after 12, 24 and 48 weeks for the best dose/regimen of IMCY-0098 defined in the first step versus placebo. (2) To determine the changes in DBS C-peptide measurements at each visit comparing each dose/regimen with placebo. (3) To determine the effects of the best dose/regimen of IMCY-0098 on HbA1c, hypoglycaemic events, Diabetes Ketoacidosis episodes, daily total insulin dose and CGM measures (4)To evaluate the impact of IMCY-0098 on autoantibodies against GAD65, IA 2, ZnT8 and insulin over time (5)To evaluate the safety features of IMCY-0098 at all doses/regimens in adult and adolescents (12-17 y.o.a). ;Primary end point(s): The DBS C-peptide measurements;Timepoint(s) of evaluation of this end point: 48 weeks | — |
