Early Conversion From CNI to Belatacept in Renal Transplant Recipients With Delayed and Slow Graft...

Delayed Graft FunctionKidney Transplant

The purpose of this study is to evaluate the safety and efficacy of conversion from a calcineurin inhibitor (tacrolimus or cyclosporine) immunosuppression therapy to Nulojix® (belatacept) immunosuppression therapy in patients with delayed (DGF) or slow graft function (SGF) following kidney transplantation. Patients at risk for SGF or DGF will be consented at the time of kidney transplantation. On post-op Day 5 the patient will be assessed, if they have developed SGF or DGF they will be randomized to convert to Belatacept or continue on their CNI regimen. Up to 20 subjects who do not develop DGF will be followed as control subjects. Seventy randomized subjects will be followed for a total of 14 months with a renal biopsy at Month 12 post transplant. Research Hypotheses: Primary Hypotheses: Kidneys with slow or delayed graft function are more susceptible to acute and long-term CNI toxicity Kidneys converted from calcineurin inhibitor based therapy to belatacept will achieve a more rapid recovery from post-ischemic acute tubular necrosis (ATN) and will have improved 1 year calculated GFR. Key Secondary Hypotheses: Renal Histology: Belatacept converted patients will have a lower chronic allograft damage index (CADI) score and lower interstitial fibrosis and tubular atrophy (IF/TA) score as calculated by Banff criteria at 1 year post- transplant Biomarker Analysis: Biomarker analysis (clusterin) measured in serial urine collections can 1) directly assess CNI induced kidney injury and 2) improve the prediction of patients that benefit in early belatacept conversion.

RUCONEST® as a Therapeutic Strategy to Reduce the Incidence of Delayed Graft Function

Kidney Failure

An unmet medical need exists for therapeutic regimens in transplantation that allow immediate postoperative graft function, thereby improving graft survival. Delayed graft function (DGF) after transplantation is the most common complication affecting kidney allographs in the immediate transplant period. The specific aim of this study is to evaluate the effect of recombinant human C1-inhibitor (rhC1INH), as a kidney recipient intra- and post operative treatment strategy to decrease systemic inflammation and decrease the incidence of DGF from donation after cardiac death donors (DCD).

Deceased Donor Biomarkers and Recipient Outcomes

Deceased Donor Kidney TransplantAcute Kidney Injury3 more

Compared to chronic dialysis, kidney transplantation provides recipients with longer survival and better quality of life at a lower cost. In order to meet increasing demands for kidney allografts, kidneys from older and sicker donors are being procured. This has led to greater discard rates of donated kidneys as well as more complications for recipients, including shorter allograft survival. Available clinical models to predict kidney allograft quality have poor prognostic ability and do not asses the degree of kidney allograft injury. However, allograft injury near the time of procurement can lead to major consequences for the transplant recipient: greater risks of delayed graft function, poor allograft function and premature loss of the transplant. Our proposal is based on the hypotheses that novel biomarkers measured in donor urine and transport media at the time of procurement can assess acute and chronic kidney injury and that distinct biomarker patterns will predict allograft survival. In collaboration with five organ procurement organizations, we will collect urine samples from consecutive deceased donors and samples of transport solution for every pumped kidney. We will measure markers of injury, repair, inflammation and fibrosis. We will determine mortality and allograft survival in all patients by linkage to the United Network for Organ Sharing (UNOS) database (Overall Cohort). Additionally, we will perform a detailed chart review of a subset of recipients (detailed cohort) and will also examine associations between biomarkers and longitudinal graft function over five years after transplant. Early, non-invasive and rapid assessment of donor kidney injury could drive better allocation decisions and potentially reduce the rates of post-transplant complications. Further, these new tools could provide a platform for clinical trials of therapies for allografts and kidney transplant recipients aimed at ameliorating allograft injury.

YSPSL for Prevention of Delayed Graft Function in Cadaveric Liver Transplantation

Liver Diseases

The study is designed to assess the feasibility of evaluating YSPSL for the amelioration of ischemia reperfusion injury following liver transplantation by administering YSPSL into the liver graft directly ex vivo via the portal vein and to the recipient intravenously prior to reperfusion. Recently, P-selectin expression has been associated in liver grafts with prolonged cold storage times and rejection. By examining biomarkers of IRI including P-selectin by immunohistochemistry and/or quantitative PCR, liver histology and hepatic blood flow using established techniques, the goal of this study is to evaluate the feasibility of using these modalities for future studies of safety and efficacy.

YSPSL for Prevention of Delayed Graft Function Part A

Delayed Graft Function

Selectins have been implicated in the pathogenesis of ischemia/reperfusion (I/R)-induced kidney injury and resultant DGF. PSGL-1 is a ligand for P-, E-, and L-selectin. It has been reported that 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.

A Study of Retrograde rEperfusion in Dbd Donor LIver Transplantation

Liver TransplantationReperfusion1 more

To evaluate whether retrograde caval reperfusion of liver graft could be superior over antegrade portal reperfusion in regard of incidence and severity of early allograft liver dysfunction. All eligible enrolled liver transplant candidates will be randomized to receive either: retrograde caval, followed by sequential portal-arterial, reperfusion or antegrade, sequential portal-arterial reperfusion.
