The study is a phase 2/3, multicenter, double-blind, parallel assignment study. It involves 100 adult recipients of an intra-hepatic pancreatic Islet Auto-Transplantation (IAT). The objective of this clinical trial is to assess whether reparixin leads to improved transplant outcome as measured by the proportion of insulin-independent patients following IAT. The safety of reparixin in the specific clinical setting will be also evaluated.
