4 Clinical Trials for Various Conditions
The purpose of this study is to understand the role of specific B cells in activating or repressing an anti-allograft immune response after kidney transplantation. In this study, blood will be collected from kidney transplant patients during different timepoints, prior to and after their transplant. Knowledge gained from study findings will be used to develop therapeutic strategies to prevent antibody-mediated rejection, which is a major cause of long-term graft loss in kidney transplant patients.
This study is designed to assess the effectiveness of eculizumab in recipients of kidney transplantation with donor-specific antibodies (DSA) and worsening kidney function and to assess if eculizumab improves endothelial cell injury in the kidney. The investigators hypothesize that complement inhibition with eculizumab will reduce allograft injury, resulting from less complement-mediated injury of endothelial cells and less endothelial cell activation.
The optimal timing for immunosuppression tapering for patients with failed kidney transplant is not known. This pilot study would be to correlate rise in cf-DNA and increase in cPRA.
This is a multi-center prospective study designed to collect blood samples from transplant patients in order to improve Natera's method for determining allograft rejection status using the donor-derived cell-free DNA analysis, called Prospera.
