The purpose of the RESTARRT study is see if a combination of two drugs, (ATG and rituximab), given at the time of the transplant surgery, will help reduce or eliminate the need for long-term immunosuppressive medication.

Alemtuzumab is a man-made antibody used to treat certain blood disorders. This study will evaluate treatment of kidney transplant recipients with alemtuzumab and other immune system suppressing medications with or without infusions of bone marrow stem cells from the kidney donor. The purpose of this study is to find out which strategy is more effective in preventing organ rejection and maintaining patient health.

Belatacept is an experimental medication shown in clinical trials to have immune system suppression properties in people who have had kidney transplants. This study will determine whether a combination of anti-rejection drugs, including belatacept, can prevent the rejection of a first-time, non-HLA identical kidney transplant and allow patients to be safely withdrawn from anti-rejection therapy one year post-transplant.

The purpose of this study is to test the safety and effectiveness of using alemtuzumab in combination with two other drugs, sirolimus and tacrolimus, to prevent organ rejection after kidney transplantation. This study will also test whether this combination of medications will allow patients to eventually stop taking antirejection medications entirely.

The purpose of this study is to determine whether a combined bone marrow and kidney transplant will be effective in treating stage II or greater multiple myeloma and associated kidney failure. This study will determine whether transplant rejection and the need for immunosuppressive drugs are decreased with this combined transplant approach.

This study examines the safety and effectiveness of a combination kidney and bone marrow transplant from a relative with the same (or nearly the same) blood cell type as the transplant recipient. An investigational medication will be given prior to and after the transplant to help protect the transplanted kidney from attack by the body's immune system.

This trial is a phase II, single arm, open-label, single center study to assess the ability of a specialized pre-transplant conditioning regimen, bone marrow transplantation and high dose post-transplant cyclophosphamide to induce tolerance and enable long-term discontinuation of immunosuppression in six kidney transplant recipients.

This study is for participants who have received up to three islet cell infusions as a previous participant in the ITN005CT study. Study participants will receive a maintenance immunosuppressive treatment regimen consisting of a combination of orally administered drugs (tacrolimus (Prograf®), sirolimus (Rapamune®), mycophenolate mofetil (MMF, Cellcept®), and/or mycophenolic acid (MPA, Myfortic®).) This protocol provides a way to supply these immunosuppressive medications to subjects whose islets continue to function and make C-peptide.

This is an observational study for people who have received a kidney transplant within the past 1 to 5 years. Researchers in this study are looking for a certain pattern of genes and cells in the blood that has been found in a group of rare transplant patients who do not need immunosuppression.

This study aims to identify which study participants - all of whom previously received a liver transplant under Campath-1H immunosuppression - exhibit specific tolerogenic genotypes. Our hypothesis is that patients who exhibit these genotypes might be good candidates for future immunosuppression withdrawal.
