YSPSL for Prevention of Delayed Graft Function Part B

Summary

Selectins have been implicated in the pathogenesis of ischemia/reperfusion (I/R)-induced kidney injury and resultant delayed graft function (DGF). PSGL-1 is a ligand for P-, E-, and L-selectin. It has been reported that YSPSL (rPSGL-Ig) blocks P-selectin and, to a lesser degree, E- and L-selectin. Both sPSGL-1 and YSPSL (rPSGL-Ig) have been shown in animal models to reduce both cytokines and tissue damage associated with ischemia reperfusion and to improve renal function post-transplant. Therefore, the current phase I/II clinical study is designed to assess the safety and efficacy of YSPSL (rPSGL-Ig) in preventing DGF in patients undergoing cadaveric kidney transplants and to determine a dose for future pivotal studies.
