38 Clinical Trials for Various Conditions
The purpose of this treatment registry study is to determine if monthly infusions of Intravenous Immunoglobulin (IVIg) for 6 months will neutralize donor specific antibodies that are thought to be responsible for chronic rejection episodes in renal transplant subjects. 162 renal transplant subjects will receive IVIg 5% at 2gm/kg/month for 6 months and be followed for 3 years.
This is a Phase II, randomized, double-blind, placebo-controlled study designed to assess the safety and clinical activity of multiple intravenous doses of MCMV5322A/MCMV3068A in cytomegalovirus (CMV)-seronegative recipients of a renal transplant from a CMV-seropositive donor, with use of a preemptive approach for prevention of CMV disease. Participants will be randomized into two treatment groups: active or placebo control; both arms will be followed preemptively. The study has a planned enrollment of approximately 120 participants (60 active and 60 placebo).
The aim of this study is to determine a comprehensive immune profile of transplant donors and recipients through assessment of immune cell compositions in bone marrow, and lymph nodes.
This study is being done to investigate the impact of changing immunosuppressive medications from tacrolimus (Prograf®) to sirolimus (Rapamune®) between 6 and 24 months post transplant. The primary purpose of this research study is to evaluate whether the use of mycophenolate mofetil(MMF)/Cellcept® and tacrolimus(TAC)/Prograf® (Group 1) or mycophenolate mofetil(MMF)/Cellcept® and sirolimus/Rapamune® (Group 2) impacts the incidence of acute cellular rejection in post kidney transplant patients. This study will examine whether switching from tacrolimus to sirolimus will better preserve long-term kidney function.
The purpose of this study is to determine whether treatment with rituximab (anti-CD20, Rituxan®, MabThera®) in individuals who develop new anti-HLA antibodies after renal (kidney) transplant will promote longer-term survival of the transplanted kidney.The pilot study compares the use of rituximab (Rituxan®) + site-specific standard immunosuppression to placebo + site-specific standard immunosuppression in the treatment of circulating anti-HLA antibodies in subjects who develop de novo anti-HLA antibodies between 3-36 months after transplant.
This study will determine the relative efficacy and safety of up to 100 days Valcyte prophylaxis relative to up to 200 days Valcyte prophylaxis when given for the prevention of CMV disease in high-risk (D+/R-) kidney allograft recipients. The anticipated time on study treatment is 3-12 months and the target sample size is 100-500 individuals.
The aim of this trial is to compare the safety and efficacy of a single dose of Thymoglobulin, rabbit derived antithymocyte globulin (Thymoglobulin, SangStat, Fremont, CA) to our standard four dose, four day Thymoglobulin induction regimen from the time of transplantation through a six month follow-up period. The primary endpoint will be the incidence of acute rejection. Secondary endpoints will include serious adverse events, evaluation of renal function, patient and graft survival, incidence of infectious complications, incidence of post-transplantation lymphoproliferative disorder (PTLD), duration and extent of lymphocyte depletion and immunoassays for evidence of recipient immune response to the allograft as well as duration of hospital stay.
A multicenter clinical study comparing event-free survival at 6 months after transplant between Thymoglobulin-treated and Simulect-treated adult kidney transplant patients. Patients received Thymoglobulin or Simulect from Day 0 through Day 4. Day 0 was considered the day of the transplant procedure. Subjects meeting all inclusion and exclusion criteria were eligible to participate in this study. The treatment assignment was random and not chosen by the subject or their physician. Subjects were monitored during treatment with Thymoglobulin and during the transplant hospitalization. Additional subject monitoring occurred up to 12 months after transplant. 278 study subjects were enrolled at 28 transplant centers in the United States and Europe.
The objective of this study is to determine the extent and magnitude of the pharmacokinetic drug interaction between mycophenolate mofetil (MFF) (under Css conditions) in the presence of iron in renal transplant recipients. A two phase pharmacokinetic study will be conducted to determine the bioavailability of MMF (under steady state, Css, conditions) in the presence of two commonly prescribed iron formulations (polysaccharide iron complex and sustained release ferrous sulfate) in renal transplant recipients. This study will evaluate valuable clinical information to help better guide the appropriate utilization of the following formulations and dosing strategies: 1. Polysaccharide iron complex concomitant administration with MMF, 2. Sustained release ferrous sulfate concomitant administration with MMF, 3. Dose separation (2 hours) between MMF and iron (polysaccharide iron complex or sustained release \[S.R.\] ferrous sulfate)
The purpose of this study is to evaluate the benefits and risks of conversion of existing adolescent kidney allograft recipients aged 12 to less than 18 years of age to a belatacept-based immunosuppressive regimen as compared to continuation of a calcineurin inhibitor-based regimen and their adherence to immunosuppressive medications.
This study will look at the effect on long-term kidney function using tacrolimus right after a transplant and then switching to sirolimus at 3 to 5 months after the transplant.
Belatacept is an experimental medication shown in clinical trials to have immune system suppression properties in people who have had renal (e.g., kidney) transplants. This study will determine whether a combination of anti-rejection drugs, including belatacept, can prevent the rejection of a first-time, non-human leukocyte antigen (HLA) identical renal transplant and allow patients to be safely withdrawn from anti-rejection therapy one year post-transplant.
An open-label study to assess the safety, efficacy, and tolerance of FCRx cell therapy in adult recipients within 12 months after kidney transplantation from a living donor.
The immune system is the body's defense against infection and other disease. After transplantation, the body sees the new organ as "foreign" and tries to destroy or "reject" it. Immunosuppressive medications help to prevent the immune system from attacking a transplanted organ. The primary purpose of this study is to investigate the impact of two maintenance immunosuppressive regimens. Subjects who enroll in this study will be randomly selected to have tacrolimus and everolimus (group 1) or tacrolimus and mycophenolate mofetil (group 2) as their immunosuppression medication. This study will enroll adult patients who are scheduled to receive a kidney transplant. The study is designed to understand the mechanisms of Everolimus in regards to kidney function in transplant recipients. The investigators hypothesis is that decreased exposure to Tacrolimus to the immune system will then translate in better renal allograft function.
The goal of this research study is to establish chimerism and avoid graft-versus-host disease in patients with kidney failure allowing a reduction or cessation of immune-suppressive therapy.
The study will compare how well transplanted kidneys work and the response of people's immune systems as tacrolimus, a calcineurin inhibitor (CNI), is withdrawn. In addition, this research study will evaluate whether reducing immunosuppression can decrease some of these side effects while still preventing rejection of the kidney.
This study will evaluate the long term safety and efficacy of AT-1501 (tegoprubart) compared with tacrolimus in patients undergoing kidney transplantation.
The objective of the proposed study is to assess whether a blood biomarker can be used to monitor the response to rejection treatment in pediatric kidney transplant recipients with biopsy-proven acute cellular or antibody mediated rejection. The study hypothesizes that blood gene expression profile and donor-derived cell-free DNA biomarkers (omnigraf) can be used to predict acute rejection and monitor its response to treatment.
Antirejection medicines, also known as immunosuppressive drugs, are prescribed to organ transplant recipients to prevent their bodies from rejecting the new organ. Some organ transplant recipients can stop taking anti-rejection medicines without rejecting their transplanted organ (this is called 'tolerance'). The purpose of this study will collect samples and data from 'tolerant' liver or kidney transplant recipients in order to find out: The purpose of this study is to collect samples and data in order to find out: * How long liver or kidney transplant recipients can remain tolerant; * What happens in the tolerant recipient's body over time; and * If there are patterns in the body that are linked to tolerance.
The purpose of this study is to determine if certain genes found in a kidney biopsy performed at one-year post transplant can predict which transplanted kidneys will have decreased kidney function within five years post-transplant.
To compare the efficacy of oral brincidofovir (BCV) to valganciclovir (vGCV) for the prevention of cytomegalovirus (CMV) disease in kidney transplant allograft recipients who are CMV seronegative pretransplant and received a kidney from a CMV seropositive donor
The purpose of the study is to determine the safety and efficacy of two dosing regimens of daclizumab in simultaneous kidney/pancreas transplant recipients.
The purpose of this study is to investigate the safety, efficacy, pharmacokinetics (PK) and pharmacodynamics (PD) of three CFZ533 dose regimens in kidney transplant recipients. This study will allow assessment of the ability of CFZ533 to replace Calcineurin inhibitors (CNIs) in terms of anti-rejection efficacy, while providing better renal function with a better safety and tolerability profile. Results of this study will be used to inform the CFZ533 dose and regimen selection for investigation in later phases of clinical development.
The purpose of this research study is to determine whether kidney transplant recipients who receive belimumab (Benlysta®), combined with the standard of care medications for kidney transplant recipients, is safe and effective in helping prevent new donor specific antibodies (DSA) after transplantation. The presence of DSA increases the risk that the kidney transplant recipient's body will reject the new kidney. The investigators are doing this research because it is estimated that greater than 50% of kidney transplant failures are attributed to antibodies produced in the body, that attack the transplanted organ as a foreign object. DSA produced in the body after a kidney transplant, is thought to occur in 20-50% of patients and is associated with a low likelihood that the organ recipient's body will accept the new kidney. A major unmet need in the kidney transplant area are safe and effective therapies to prevent DSA after transplantation.
The TEAMMATE Trial will enroll 210 pediatric heart transplant patients from 25 centers at 6 months post-transplant and follow each patient for 2.5 years. Half of the participants will receive everolimus and low-dose tacrolimus and the other half will receive tacrolimus and mycophenolate mofetil. The trial will determine which treatment is better at reducing the cumulative risk of coronary artery vasculopathy, chronic kidney disease and biopsy proven-acute cellular rejection without an increase in graft loss due to all causes (e.g. infection, PTLD, antibody mediated rejection).
Background: Proteinuria develops in about 30% of kidney transplant recipients and is a strong predictor of graft loss. The amount of proteinuria has a direct correlation with the risk of graft failure. Novel therapies are urgently needed to reduce proteinuria and prevent graft loss in transplant recipients, since ACE inhibitors carry a number of limitations in the transplant setting, including significant reduction in renal function, anemia and hyperkalemia. Preliminary data: B7-1 is expressed at significant levels in about 10% of kidney allograft biopsies with predominance in patients with proteinuria. Hypothesis: We hypothesize that B7-1 targeting therapy may reduce proteinuria and improve graft survival in proteinuric transplant recipients that have B7-1 staining on allografts. In addition, the absence of CNI nephrotoxicity and the potential protective effect of Belatacept on DSA production may be of benefit in this subset of transplant patients. Objectives: Primary: Determine the effect of Belatacept conversion in reducing proteinuria by 25% at 12 months in renal transplant recipients (≥1gram/d) that are either B7-1-positive or negative on kidney biopsy. Secondary: Assess the effect of Belatacept conversion in the percent change of renal function from baseline to 12 months; donor-specific anti-HLA antibodies presence and intensity (MFI); correlation of B7-1 positivity on immunofluorescence on biopsy with B7-1-expression in urine extracellular vesicles; adverse events; acute rejection episodes; blood pressure control; new onset diabetes; hyperlipidemia; graft survival; and patient survival.
An open-label study to assess the safety, tolerability, and efficacy of FCR001 cell therapy in adult recipients 3-12 months after kidney transplantation from a living donor.
Chronic Allograft Nephropathy (CAN)/Interstitial fibrosis and Tubular Atrophy (IFTA) is responsible for most kidney transplant failures. CAN/IFTA on a 3 month kidney biopsy strongly predicts graft survival long term. CAN/IFTA remains a vexing problem for clinicians because current monitoring tools, namely the serum creatinine concentration, are not sensitive to early changes in glomerular filtration rate (GFR) or to histologic damage. Despite advances in prevention of acute rejection (AR), it is still a significant and potentially devastating complication of solid organ transplantation. One strategy to reduce the risk of rejection is to perform kidney biopsies to detect subclinical acute rejection (SCAR) and treat to prevent progression to rejection. There is evidence that treating SCAR can prevent further immune mediated injury to the kidney, a precursor to CAN/IFTA. Kidney biopsies provide better information but are limited due to safety concerns, patient preference and cost issues. Better, early and less invasive markers of CAN/IFTA will allow early intervention as well as improved graft and better patient outcomes. This study seeks to validate specific proteogenomic biomarker panels for AR and CAN/IFTA in a prospective blood, urine and kidney tissue monitoring study of kidney transplant recipients who will be scheduled for standard of care biopsies.
The purpose of this multi-center (observational) registry study is to establish a database of clinical and laboratory information that may help to identify any unique characteristics of tolerant participants that differ from participants who reject their kidney after discontinuing immunosuppressive drugs.
There is a need to develop blood and/or urine tests that will help to detect early signs of rejection in people who have had kidney transplant. Researchers will examine blood, urine, and tissue samples and try to identify genetic markers for certain conditions like rejection, response to therapy, and scarring of the kidney. By studying gene patterns, researchers hope to be able to diagnose these conditions earlier and improve kidney survival.
