Filter by:The purpose of the study is to test the safety and feasibility of autologous mesenchymal stem cell therapy in HLA-DR mismatched patients with subclinical rejection and or an increase in IF?TA in the renal biopsy 4 weeks or 6 months after renal transplantation.
Acute rejection is a common problem after a kidney transplant. Rejection can occur when the kidney recipient's immune system tries to attack (or reject) the new kidney. Rejection typically most often develops in the first few months after a transplant. This single center study will seek to determine if a new combination of anti-rejection medications, including the recently FDA approved drug called Belatacept, is better than the current standard anti-rejection drug regimen at preventing rejection. Also to be determined will be whether the new combination of drugs will allow participants to wean off their oral anti-rejection medications over time. This study will test the safety and effectiveness of a new investigational drug combination using alemtuzumab, belatacept, and sirolimus when given with or without donor bone marrow. This combination of medicines has not been tested before in humans. Alemtuzumab (Campath) is approved for use in some types of white blood cell cancers, but is considered investigational in transplant patients. Belatacept is now FDA approved and is being studied in transplant patients. Sirolimus (Rapamune) is approved for use in transplant patients, but its use with belatacept and alemtuzumab is investigational. In the initial 20 subjects enrolled in the study, half tested whether an infusion of bone marrow from the kidney donor would improve the effect of these drugs. This bone marrow infusion was also considered investigational. Enrollment of 20 additional subjects began in January, 2013. The donor bone marrow infusion has been eliminated. Enrollment was open to primary living and deceased donor kidney recipients. Enrollment was closed as of 8/12/2014.
Liver transplant subjects will be given Mycophenolate (MMF) and Tacrolimus in order to help prevent post-transplant rejection.
This study sought to determine the safety of the varicella vaccine pre- and post-transplantation when given to pediatric patients listed for solid organ transplantation. The study assessed the antibody response to a two-dose vaccine regimen and determined the durability of that antibody response at several intervals in the post-transplant period. As a secondary objective, the relationship between antibody titers and different variables were explored
