a study on Pancreatitis
The study will be a phase 2/3, multicenter, double-blind, parallel assignment study. It will involve 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.
A Phase 2/3, Multicenter, Randomized, Double-blind, Placebo-controlled, Parallel Assignment Study to Assess the Efficacy and Safety of Reparixin in Pancreatic Islet Auto-transplantation
In contrast to allo-transplantation in type 1 diabetes patients, where immunological mechanisms involving allo- and auto-antibodies affect long-term graft function, outcome in IAT (Islet Auto-Transplantation) is independent from immunological processes and does not require immunosuppression management. On the other hand, early inflammatory events intrinsic to the intra-portal islet infusion have been demonstrated to impact islet engraftment. Among possible mechanisms, PMNs have been found to be the predominant cell types infiltrating the liver in a syngeneic model of islet transplantation in mice.
Data obtained in experimental models of islet transplantation in mice demonstrate a clear effect of reparixin in improving graft survival and function. Protection from the loss and/or deterioration of transplanted islets was evident regardless of the immunological mechanisms involved in islet damage, suggesting that the ability of reparixin to modulate early inflammatory responses readily impact graft outcome.
Thus, the use of reparixin may emerge as a potential useful medication in the control of non specific inflammatory events surrounding the early phases of IAT.
The goal of this study is to reach a total of 100 adult patients who are randomized and receive IAT after total or completion pancreatectomy. Patients will be randomly (1:1) assigned to receive either reparixin [continuous i.v. infusion for 7 days (168hrs)], or matched placebo (control group),starting approximately 12hrs before islet infusion. The two groups will be balanced within each centre. All patients who are randomized and receive the Investigational Product (either reparixin or placebo) will be inlcuded in the ITT analysis. Patients will be in the ITT analysis whether or not they receive IAT, because exclusions cannot be made for events occurring after randomization that could be influenced by the randomized assignment.
Recruitment will be competitive among the study sites, until the planned number of patients is enrolled. Competitive recruitment has been chosen to increase the speed of recruitment and to account for any difference in transplant rate among study sites. Each centre will enroll patients as rapidly as possible, up to a maximum of 40 patients (as per the randomization list).
Each patient will be involved in the study for 7 day hospital stay during pancreatectomy followed by islet transplantation, for all required measurements up to hospital discharge and for 2 post-transplant visits scheduled @ day 75+14 and 365+14 after the transplant.
