Outcomes

Primary Outcome Measures

Incidence of all adverse events reported for subjects
Safety assessed through measurement and comparison of any reactions or hypersensitivity to IMCY-0098 injection vs placebo. Number of adverse events will also be compared between groups with the addition of safety monitoring blood tests

Secondary Outcome Measures

Assessment of residual beta cell function and markers of metabolic control
Measured by a change in stimulated C-peptide production, daily insulin usage, glycated haemoglobin levels and glucose levels and excursions from baseline and between groups

5. Study Description

Brief Summary
This clinical study will evaluate the safety of an innovative approach expected to be disease-modifying by stopping the auto-immune-mediated destruction of islet β-cells in the pancreas. Three doses of the investigational product will be tested in successive cohorts. Although safety is the first objective of this study, we will gather efficacy data and perform a set of immunological tests to further understand the mechanism of action of this new approach in young adults with recent onset type 1 diabetes.
