Immune Profile in Subjects With New Onset Type 1 Diabetes

It is hypothesized that early changes in the immune system in New Onset Type 1 Diabetes Mellitus (NOT1D) subjects can be detected in immune cells from the inguinal lymph nodes (iLN), which will be distinct from changes observed in peripheral blood derived immune cells. Therefore this study will assess and compare the molecular immune profile of cells derived from the iLN in healthy and NOT1D subjects, to understand the immunological processes that may lead to beta cell destruction. It is a multi-center, non-drug treatment study. Up to 15 subjects in each group, namely healthy subjects and NOT1D subjects, will be evaluated in the study. A data look will be carried out after the recruitment of a cohort of up to 5 healthy subjects, to determine if the quality and quantity of cells derived from aspirate or core biopsy or from peripheral blood are likely to be sufficient to continue the study to meet its primary objective. An interim analysis will be carried out after the recruitment of 5 evaluable healthy subjects and 5 evaluable NOT1D subjects. The primary purpose of this interim analysis will be to facilitate decision making and study design for a potential follow-up interventional study.
