83 Clinical Trials for Various Conditions
Randomized open label clinical trial in which 48 renal transplant recipients with inflammation in the 6 month allograft biopsy will either continue usual immunosuppression or receive monthly Actemra (Tocilizumab) infusions for 6 months in addition to usual immunosuppression.
The purpose of this study is to test the safety of the experimental therapy of a single infusion of Regulatory T cells (Tregs). The investigators want to find out what effects, good or bad, Tregs will have on the kidney transplant patients. There are different types of T cells. This study uses Regulatory T cells (Tregs), which are found in the blood and are part of the immune system that stops other immune cells from working. Tregs help to turn off the immune system after other immune cells have finished tackling outside infections, and Tregs keep the immune system in check so that the body does not attack itself. The researchers are hoping that, by giving an infusion of Tregs that the attack on the kidney can be stopped and kidney function will be stabilized. It is not known if the Treg experimental therapy can stop the inflammation in the kidney. In this study, the researchers will take some of Tregs from the patient, multiply them in the laboratory, and then infuse them back into the patient. The procedure used to multiply Tregs is an experimental process performed in the laboratory. Similar procedures done with mice have been shown to reverse inflammation but it is not known whether the results will be the same in humans. This therapy has not yet been done in humans outside of a research study.
This study is being done to evaluate the effectiveness of a Sun Protection Strategies workbook for kidney transplant recipients. Since the medication taken to preserve the kidney transplant puts kidney transplant recipients at an increased risk of developing skin cancer. The program will help people learn about how to practice effective sun protection after the transplant.
This study is being done to evaluate the effectiveness of a Sun Protection Strategies internet-based program for kidney transplant recipients. Since the medication taken to preserve the kidney transplant puts kidney transplant recipients at increased risk of developing a sunburn as well a skin cancer, the program will help people learn how to practice effective sun protection for their condition.
Cardiovascular disease is the leading cause of mortality in kidney transplantation. The enzyme xanthine oxidase may play an important role in the cardiovascular disease of kidney transplant recipients. Inhibiting this enzyme with allopurinol may improve vascular health and protects against cardiovascular complications.
The primary purpose of this study is to measure the correlation between baseline expression of aging biomarkers, SenesceTest in blood of organ donor and renal graft function. This pilot study will study patients who are undergoing renal transplantation with organs from extended criteria donors, standard criteria donors or donation after cardiac death and compare ability of SenesceTest to predict renal graft function immediately after the transplant and at 1 year followup.
The purpose of this study is to determine whether a single administration of QPI-1002 (also known as I5NP) can prevent DGF in patients undergoing deceased donor kidney transplantation. In this Phase I /II study, patients who are undergoing renal transplantation with organs from DCD donors, ECD donors or SCD donors with ≥ 24 hours of cold ischemia time who meet study entry criteria will be studied to evaluate the safety and pharmacokinetic profile of I5NP (Part A) and clinical activity of I5NP administration (Part B). Data from this study will be used to identify doses of I5NP to be used in follow-on efficacy studies. Part A will be a randomized, dose escalation study to determine the highest or maximum tolerated dose (MTD). Part A will enroll 40 patients at approximately 20 sites; patients will be randomized to receive either I5NP or placebo in a ratio of 8:2 in each cohort (cohorts 1-4). Part B will utilize the dose identified in Part A to further evaluate, in a double-blind manner, the safety, and clinical activity of I5NP. In Part B, up to 326 patients will participate at approximately 60 sites; up to 163 patients will be randomized to receive I5NP and up to 163 patients randomized to receive placebo.
This project will be a single-arm feasibility study, with a treatment intervention that includes three interrelated components: (1) patient education using a proven weight loss curriculum, and (2) technology tools for making healthy lifestyle choices.
The purpose of this research is learn about how OmniGraf works in kidney pancreas transplant patients. Also, to analyze the performance characteristics of OmniGrafTM (TruGraf Gene Expression Profiling (GEP) and T Cell Receptor Alpha Constant (TRAC) dd-cfDNA) in a population of simultaneous kidney pancreas transplants as a part of routine surveillance, as well as a part of the workup for patients clinically suspected to have rejection of the kidney and/or pancreas.
Long-term allograft function in kidney transplant recipients (KTRs) remain suboptimal, and graft failure causes significant morbidity and mortality, with cardiovascular disease being the leading cause of death in KTRs and the most common cause of death with a functioning graft. Sodium-glucose cotransporter 2 (SGLT2) inhibitors safely lower cardiovascular and kidney disease risk in the non-transplant population, yet data in KTRs are lacking. This clinical trial seeks to establish the efficacy and safety of dapagliflozin, a SGLT2 inhibitor, for improving cardiovascular and kidney graft function in adult KTRs with type 2 diabetes and post-transplant diabetes, and to leverage innovate translational methods to define the underlying mechanisms of action.
EFFEKTOR is a vanguard, multicenter, phase 2 randomized, double blinded, placebo controlled clinical trial to determine the feasibility, tolerability, safety, and efficacy of finerenone in kidney transplant recipients (KTRs). One hundred fifty (150) KTRs will be randomized in a 2:1 ratio of finerenone to placebo, with two embedded substudies: (i) a kidney biopsy substudy in 50 participants who undergo a research kidney biopsy prior to randomization and at the end of active treatment; and (ii) a functional MRI (fMRI) substudy in 50 participants who undergo fMRI prior to randomization and at the end of active treatment.
This study is being done to compare the effectiveness of de novo Letermovir versus valganciclovir in preventing the development of cytomegalovirus viremia or symptomatic disease in African American kidney transplant recipients within the first year after transplantation. There are two arms in the study: Arm 1: Prophylaxis: This group includes freshly transplanted high risk (CMV D+/R-) African American Kidney recipients who will be on prophylactic Letermovir for 6 month. Arm 2: Prophylaxis: This group includes high-risk African American kidney transplant recipients who had already completed the 6 month prophylactic course with the standard of care Valganciclovir.
Randomized controlled trial of a curriculum intervention teaching patients to eat a whole-food plant-based dietary pattern versus standard of care in kidney transplant recipients within the first few months of transplant
The purpose of this study is to evaluate whether the use of the Viracor® CMV immunity assay at 6 months post-transplant in CMV high risk kidney transplant recipients would help identify those patients at higher risk of post-prophylaxis CMV viremia or disease and thereby select those patients in which a longer duration of valganciclovir prophylaxis would be beneficial.
This study aims to compare the effectiveness of a regional anesthetic block vs systemic intravenous (IV) lidocaine in controlling post-operative pain in kidney transplantation patients. Regional anesthetic blocks and lidocaine infusions are effective alternatives to opioid medications and are already in use at many institutions. However, there has been no prospective study comparing their effectiveness when used in conjunction with the current standard of care patient controlled analgesia (PCA) pumps. This study is a prospective, randomized evaluation of both treatment methods.
Older patients with end- stage kidney disease (ESKD) are at very high risk for functional impairment. Kidney transplantation (KT) has the potential to ameliorate the detrimental effects of ESKD on physical activity and functional status. However, KT alone may not meet the full extent of this potential, particularly for older or more impaired adults. In fact, activity declines immediately post-KT and fails to return to expected levels even 5 years post-KT. Older patients waitlisted for KT (most of whom are on dialysis) are therefore reliant on their pre-KT levels of exercise, which are also predictive of post-KT mortality. "Prehabilitation" has been used in other surgical populations to minimize functional loss, and a structured exercise program may be beneficial in the pre- KT setting. However, few waitlisted patients are able to participate in typical exercise interventions due to barriers such as severe fatigue. Older patients have additional barriers such as further mobility impairment and requiring substantial caregiver support. Therefore for older living donor kidney transplant candidates, it is necessary to address issues such as specifics of coaching, timing, and importantly, incorporate caregiver participation. The overall objective of this proposal is to adapt a previously developed 8- week, home- based, structured exercise program among older (≥50 years) dialysis patients awaiting living donor KT, with a focus on caregiver involvement. The investigators will trial the exercise program as compared to usual care. The investigators will then pilot the refined intervention in a total of 72 patient-caregiver dyads, 48 of whom will undergo the proposed intervention (24 with caregiver participation, 24 without). The primary outcomes for the pilot will be change in physical performance and activity from baseline to after the intervention, along with measurements of exploratory quality of life outcomes. In addition, the investigators will measure these same outcomes at 3- months post KT to evaluate for a durable effect of the intervention. An additional post-transplantation outcome of interest will be number of days hospitalized within 3 months of transplantation.
CREST-KT is a single-center, double-blinded, randomized trial of empagliflozin therapy in 72 kidney transplant recipients with (n=36) and without type 2 diabetes (n=36). After evenly dividing patients by type 2 diabetes diagnosis, patients will be randomized 2:1 to empagliflozin 10mg versus placebo.
The investigators want to study the impact CGM (continuous glucose monitoring) has on patients glycemic control as determined by time in range (TIR 70-180 mg/dL) in the Diabetic Kidney Transplant population.
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.
Intra-patient variability (IPV) in tacrolimus is associated with premature graft loss. The rate of acute rejection episodes is higher in these patients, and acute rejection impacts negatively on graft survival. The prevalence of patients with high IPV is higher in African American patients (1-5). At the kidney transplant program of the University of Maryland, our investigators follow over 2.800 patients, with approximately 50% of the patients being of African American heritage, thus an ideal setting for the study.
The purpose of this research study is to determine the effectiveness of educational videos for patients who have just had kidney transplant compared to usual patient education practices. Eligible patients will have the opportunity to enroll in this study after their transplant procedure either before hospital discharge or at their first follow up clinic visit.
This study will assess the immune responses to the recombinant, AS01-adjuvanted varicella zoster virus subunit (HZ/su) vaccine or SHINGRIX in immunosuppressed patients, particularly those who have received a renal transplant, and aim to better understand if the vaccine and perhaps other adjuvanted vaccines are safe in these patients. 30 participants will be divided into 2 groups, one group will receive the 1st out of 2 doses of the vaccine 3-6 months after transplant per standard of care and the second group will receive the 1st out of 2 doses of the vaccine 12-36 months after the transplant per standard of care.The duration of the study is 180 days.
The purpose of this study is to compare two medications that reverse muscle paralysis at the end of kidney transplant surgery with the goal of reducing residual muscle weakness and insufficient respiratory function after surgery.
Transplant patients must take lifelong immunosuppression in order to prevent rejection of their organ. Tacrolimus is the most widely used immnosuppressive agent. Part of the routine education given to patients regarding tacrolimus is that they must avoid many drugs and substances that can interact with tacrolimus so that they don't experience side effects or lack of effect. Patients are told they must avoid readily available substances such as grapefruit juice and St. John's wort. A new once daily formulation of tacrolimus, Envarsus XR, may bypass the place in the gut in which many of these drug interactions occur. We will give kidney transplant patients Envarsus with and without grapefruit juice and measure the effect on blood levels throughout the day. Results from this study will also give us information about the likelihood of other drugs interacting with Envarsus XR.
The primary purpose of this study is to evaluate the pulse wave velocity and vascular compliance measurements at the beginning and the end of the study while the participants are taking either extended release tacrolimus tablets (known by brand name Envarsus XR®, and also referred to as LCPT in this study) given once-daily each morning after transplantation or immediate release tacrolimus capsules (also known by brand name Prograf® or abbreviation IR-TAC in this study) that are administered twice-daily 12 hours apart after kidney transplantation. Pulse wave velocity and vascular compliance measurements are two non-invasive tests that are used to evaluate how well the blood vessels adapt to each heartbeat. The secondary purpose is to look at the effectiveness and safety of LCPT given once-daily compared to IR-TAC given twice-daily 12 hours apart after kidney transplantation.
One possible reason that weight gain after transplant may interfere with new kidney function is due to the enlargement of a kidney structure called the glomerulus. The researchers believe that modest caloric intake reduction (CIR) early after kidney transplantation can reduce the enlargement (hypertrophy) of the glomerulus associated with kidney transplantation and may improve long term allograft survival, by reducing glomerular hypertrophy mediated progressive glomerulosclerosis.
The purpose of this research study is to determine whether an immunosuppressive maintenance regimen of Envarsus/azathioprine compared to a tacrolimus/ mycophenolic acid regimen is associated with better compliance, tolerability, and lower biopsy proven rejection.
There is an increasing number in patient's undergoing kidney transplantation in the United States. Furthermore, kidney recipients have high occurrence of 30-day readmissions that leads to high hospital costs and decreased quality of life for transplant recipients. A previous research finds that high levels of post-transplant anxiety is correlated with increased likelihood of 30-day readmissions. The goal of this study is to design and implementat a randomized control trial (RCT) using a standardized post-transplant mentoring program in order to reduce 30-day readmission and post-transplant anxiety among recipients.
Previous studies have shown that elderly patients experience higher trough levels of tacrolimus and are more sensitive to the effects of medications, they experience higher occurrence and severity of such medication related toxicities. Therefore, the investigators hypothesize that by transitioning patients from tacrolimus immediate release to Envarsus ®, the peak-dose effect will be eliminated or attenuated, leading to a significant decrease in neurocognitive toxicities in the older patient population.
This investigator-initiated post-marketing study will evaluate the role of Hispanic ethnicity on drug dosing of Envarsus in first-time stable renal transplant recipients. Tacrolimus trough drug levels will be studied as a primary endpoint at 24 hours after drug dosing and at steady state (e.g., trough level at 3 months post conversion) and secondary compliance assessments will be done by pill counts at clinic visits. Secondary outcomes will be the safety of once a day dosing as well as assessment of graft rejection and graft failure. In addition, concentration/dose ratios will be analyzed. The results of this study will provide important information about dosing of once a day tacrolimus (Envarsus) in Hispanic kidney transplant patients, which represents the largest growing group of patients with End-Stage Renal Disease
