Mycophenolic Acid Monotherapy in Recipients of HLA-identical Living-Related Transplantation

This randomized trial will enroll adult recipients of HLA-identical living kidney transplants who are at least 1 year post-transplant. All subjects will be taking Prograf (tacrolimus) or cyclosporine and mycophenolic acid (CellCept or Myfortic) and then be randomized (1:2) to either continue calcineurin inhibitors or to taper off of calcineurin inhibitors. The hypothesis is that mycophenolic acid monotherapy permits long-term rejection-free renal allograft function in the abse...

Letermovir Treatment for Refractory or Resistant Cytomegalovirus Infection

The trial will evaluate the safety and efficacy of letermovir antiviral treatment of active cytomegalovirus infection or cytomegalovirus disease in patients with infections that are refractory or resistant to available treatments or who are experiencing organ dysfunction that makes unsafe the use of available antiviral treatments.

Extension of Letermovir (LET) From Day 100 to Day 200 Post-transplant for the Prevention of Cytomegalovirus (CMV) Infection in Hematopoietic Stem Cell Transplant (HSCT) Participants (MK-8228-040)

The purpose of this study is to evaluate the safety and efficacy of letermovir (LET) versus placebo when extended from 100 days to 200 days post-transplant in cytomegalovirus (CMV) seropositive participants who received an allogenic hematopoietic stem cell transplant (HSCT). It is hypothesized that LET is superior to placebo in the prevention of clinically-significant CMV infection when LET prophylaxis is extended from 100 to 200 days.

Pediatric Kidney Transplant Without Calcineurin Inhibitors

The purpose of this study is to see the effect of using drugs other than calcineurin inhibitors to improve the rate of kidney transplant failure. Kidney transplantation can help children with end-stage kidney disease. However, it has been difficult to find treatment for donor graft rejection that does not have a lot of side effects. Researchers hope to find treatments (immunosuppressants) with fewer side effects. One approach is to avoid using calcineurin inhibitors and to try...

Observational Trial of Hepatitis C Virus Infected Patients on Calcineurin Inhibitors

Hepatitis C Virus is constantly evolving genetically, particularly in response to the immune system. This is an observational study to examine if immunosuppressants particularly calcineurin inhibitors taken by transplant patients in order to avoid organ rejection causes predictable changes in the genetics of this virus that might be important in order to treat it effectively.

Study to Evaluate the Value of the Follow-up of CALCIneurin Activity to MOdulate Calcineurin Inhibitors-induced Immunosuppression in Lung Transplantation

The study is an interventional, multicentre, prospective, randomized, controlled, single-blind, comparative trial of two processes for adjusting the inhibitor of calcineurin (CNI) dosage in lung transplant recipients. Recipients will be stratified by transplant center and according to the underlying lung disease (affected with cystic fibrosis or not) and will be randomized to either evaluation of calcineurin activity (CN-a) in combination with CNI blood levels versus CNI blood ...

Safety Study of Calcineurin Inhibitor Free GvHD Prophylaxis in Allogeneic Stem Cell Transplantation

In stem cell transplantation as treatment for malignant diseases, calcineurin inhibitors like cyclosporine A are commonly used to prevent tissue destruction (GvHD) by activated donor immune cells. The hypothesis for this study is, that replacing calcineurin inhibitors by everolimus and mycophenolate as GvHD prophylaxis not only reduces toxicity of the treatment but also improves tolerance induction of the donor T cells toward the host, eventually increasing the safety of stem c...

Campath, Calcineurin Inhibitor Reduction and Chronic Allograft Nephropathy

The 3C study will investigate whether reducing exposure to calcineurin inhibitors (by using more potent antibody induction treatment and/or an elective switch to sirolimus) can improve the function and survival of kidney transplants.

A Study of CellCept (Mycophenolate Mofetil) Combined With Calcineurin Inhibitors in Liver Transplant Patients.

This 2 arm study will compare the efficacy and safety of switching to CellCept combined with different regimens of reduced calcineurin inhibitors (CNI) in patients with liver transplants. Patients currently receiving CNI treatment will be randomized into one of 2 groups to receive either 1) CellCept 2.0g/day po bid + 50% reduction of CNI from baseline or 2) CellCept 2.0g/day po bid + >=75% reduction of CNI from baseline. The anticipated time on study treatment is 1 year, and th...

Study Comparing Conversion to Sirolimus vs. Continued Use of Calcineurin Inhibitors in Kidney Transplant Recipients

The purpose of this study is to determine the effect of conversion from calcineurin inhibitor to sirolimus based therapy on renal function.

L-arginine for Prevention of Kidney Damage in Liver Transplant Recipients

Chronic renal insufficiency is a common and important health problem that causes morbidity and mortality among patients who have undergone liver transplantation. It is mainly caused by drugs (calcineurin inhibitors) that are used to prevent or treat rejection and once established, there is no effective treatment. This research investigates whether L-arginine can reverse the effects of calcineurin inhibitors on the kidneys and thus prevent renal insufficiency in liver transpla...

Rapamycin and Regulatory T Cells in Kidney Transplantation

The immune system response is mediated by the interaction between the antigen presenting cell (APC), CD4+ T helper cells (Th) and CD4+ CD25+ regulatory T cells, a subgroup of CD4+ T cell which express IL-2 receptor (CD25) and the transcriptional factor foxp3. Regulatory T cell may contribute to the maintenance of tolerance by suppressing the immune response to normal or tumor associated antigens. Regulatory T cell emerge from the thymus during ontogenesis and they represent ab...

Letermovir Versus Valganciclovir to Prevent Human Cytomegalovirus Disease in Kidney Transplant Recipients (MK-8228-002)

The primary objective of this study is to evaluate the efficacy of letermovir (LET) versus valganciclovir (VGCV) in preventing CMV disease in adult kidney transplant recipients. The primary hypotheses are that LET is non-inferior to VGCV; and if non-inferiority is demonstrated, that LET is superior to VGCV, in preventing CMV disease through 52 weeks post-transplant.

Pharmacokinetic (PK) Study of Single-Dose Rosuvastatin and Tipranavir/Ritonavir in Healthy Subjects

Tipranavir (TPV) plus ritonavir (RTV) is indicated for use as part of an antiretroviral treatment regimen for resistant HIV-1 infection in adult patients. Since significant cholesterol and triglyceride elevations are commonly reported during TPV/RTV treatment, effective treatment strategies are critical to prevent long-term cardiovascular events. Rosuvastatin, a potent HMG-CoA reductase inhibitor, is unlikely to interact with TPV/RTV since it is not extensively metabolized, how...

A Pilot Study of Campath-1H Induction Therapy Combined With CellCept® Therapy to Allow for a Calcineurin Inhibitor Free Regimen After Renal Transplantation

The hypothesis of this study is that lymphocyte depletion by Campath-1H and rituximab will obviate the need for long-term calcineurin inhibitors in renal transplantation. Most successful strategies to date have relied on the use of either tacrolimus or cyclosporine. However, the advantage of a calcineurin inhibitor free regimen may include improved renal allograft function, a lower incidence of hypertension, diabetes, and less drug related side effects. This is a non-randomiz...

Calcineurin Inhibitor Minimisation in Renal Transplant Recipients With Stable Allograft Function

The purpose of this trial is to ascertain whether the withdrawal of calcineurin inhibitors (CNI) will lead to less kidney transplant damage when compared with minimisation. The investigators will assess this by comparing the degree of damage on kidney biopsies taken before and after minimisation/withdrawal of CNI.
