Study of IMCY-0098 in Patients With Recent Onset Type 1 Diabetes

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.
