E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The aim of this study is to test the efficacy and safety of a marginal islet transplantation associated with immunosuppressive treatment / modulatory transient therapy for type 1 diabetes onset |
|
E.2.2 | Secondary objectives of the trial |
- Assess the impact of treatment on the immune response of memory and autoimmune in new onset type 1 diabetes
- Identify biomarkers that reflect the sensitivity or resistance to the potential benefits of treatment on β-cell function

E.3 | Principal inclusion criteria |
Males and females aged 18-45 years

- Use of investigational drugs within 4 weeks of enrollment.
- The administration of live attenuated vaccine within 2 months thereafter
- Any medical condition that, in the opinion of the investigator, would interfere with the safe participation in the study.
