Nephrotic syndrome is a condition which affects the kidneys causing them to leak protein from the blood into the urine. Nephrotic syndrome is a disease that can improve (remission) and worsen (relapse) at different times throughout childhood. By collecting health information and laboratory samples, our goal is to learn more about these kidney diseases and find better ways to prevent and treat people with nephrotic syndrome. New knowledge will be shared with researchers and the public.

The purpose of this study is to determine the safety and efficacy of the Vanquish System treatment in men who have intermediate risk prostate cancer. In this study, the Vanquish System will be used to destroy cancerous tissue in the prostate. After treatment, participants will undergo tests that will assess presence of prostate cancer.

This trial will evaluate other treatment options for high-risk NMIBC patients who were unresponsive to Bacillus Calmette Guerin (BCG therapy). We are studying two different drugs in combination with pembrolizumab. Participants will receive up to 35 doses of the trial drug and have tumor assessments for about 2 years. This will be followed by treatment tumor assessment for another 3 years for a total trial duration of 5 years.

The purpose of this study is to test whether the investigational drug, tegoprubart, in combination with the same standard immunosuppressive medicines (anti-thymocyte globulin, corticosteroids, and mycophenolate) is safe, tolerable and effective compared to tacrolimus. The study will specifically look at the function of the implanted kidney in the tegoprubart group compared to the tacrolimus group and will also assess how well tegoprubart prevents diabetes and prevents rejection.

The purpose of the trial is to evaluate the effect and safety of imlifidase when given to participants with antiGBM disease (also called Goodpasture disease). We will study if the addition of imlifidase to the standard of care treatment results in a better effect without causing unacceptable side effects compared to standard of care alone.

The aim of this study is to investigate whether voclosporin, added to standard treatment, is able to reduce activity of lupus nephritis over a study treatment period of 24 weeks, and to determine its safety as well as the best dose for treatment of lupus nephritis in children or adolescents.

Currently, there are no approved treatment options for pediatric subjects with proteinuric kidney conditions. The study will look at the safety, efficacy, and pharmacokinetic (PK) trial in children ≥1 to <18 years treated for up to 108 weeks with the drug sparsentan.

The purpose of this study is to assess the safety and effectiveness of the Butterfly study device in reducing the symptoms that are associated with the BPH condition. Another purpose is to assess sexual function and quality of life following the use of the Butterfly study device. The Butterfly study device includes a metal (nitinol) implant that looks like a butterfly. The implant is inserted through the urethra - the tube that carries pee out of the body, and resides at the area of the prostate.

The goal of this study is to understand how urine and bladder tissue changes from infection, or a bladder that does not function normally, in people who use a catheter to empty their bladder. This may help future people because it can help determine who needs antibiotics to treat an infection in the bladder, and will help avoid the cost and side effects of using antibiotics in people who do not have a true infection. This study will take less than 1 hour – the time required to provide a urine sample in clinic. Or, if a participant is undergoing bladder Botox injection, the time necessary to participate in the study will add approximately 5 minutes to the total surgery time.

We are testing whether treating people who have FSGS with plasmapheresis and rituximab before or shortly after kidney transplant can prevent the recurrence of FSGS after kidney transplant. All participants will receive plasmapheresis. Each participant has a 50% chance of receiving rituximab and a 50% chance of receiving no additional treatment. Rituximab is given by infusion. If a participant is assigned to receive rituximab, it will be given one time immediately after plasmapheresis.

People with Primary MN lose more protein in their urine because the filters in their kidneys may be damaged. It is possible that some belimumab may also be lost in the urine because of this. This study will measure belimumab in the blood to decide if people with high urine protein should receive a higher dose of belimumab. Another purpose of this study is to help learn about whether the combination of belimumab and rituximab treatment is effective in making and keeping Primary MN inactive.

The Kidney Precision Medicine Project (KPMP) is a research study. Our goal is learn more about kidney injury and kidney disease. By studying your kidneys, we may learn more about why chronic kidney disease happens and how to treat it more effectively or even how to prevent it. Or participants have had diabetes for many years and have not clinical signs of chronic kidney disease. By studying your kidneys, we may learn more about the factors that help protect you from kidney disease. KPMP will last for at least 10 years.

The main purpose of this study is to check how safe the study drug is and how well your body handles taking it. We will also check if the study drug works to improve your kidney function, if has an impact on your daily life and the amount of the study drug in your blood over a period of time (called pharmacokinetics)

The purpose of the research is to find out if atrasentan delays worsening of kidney function in IgAN, FSGS, and Alport Syndrome.

This study will evaluate treatment satisfaction, discontinuation, reasons for discontinuation, quality of life, healthcare resource utilization, and safety with vibegron for the treatment of OAB in the context of real-world clinical practice.

The purpose of CureGN2 is to gather a group of people with glomerular disease to create a source of information and blood and urine samples, so that researchers can easily and effectively study glomerular disease.

The maintenance of normal body temperature is important for all patients undergoing anesthesia to maintain important body functions. To help patients maintain normal body temperature during the surgery, a warming device is used. This study will compare the effectiveness of a resistive blanket warming device to the standard of care forced air warming device.

This study is being done to improve outcomes after kidney donation and kidney transplantation. We will test kidney donors and kidney transplant recipients for apolipoprotein L1 gene (called APOL1) variants (or forms of the gene) and to see how these may affect them. Genes control the traits inherited from your family such as your eye color or blood type. Only a blood sample (and possibly urine) will be collected. Information routinely collected as part of surgery will also be used in the study. There will not be any changes to usual medical care.

The effect of enzyme replacement therapy on how well your kidneys are responding to enzyme replacement therapy (ERT) is not clear from blood and urine tests alone, but may be more clear in comparisons of kidney biopsies performed before and some time after ERT has been initiated, and this is what we are focusing our study efforts on. The purpose of this study is to obtain your permission to allow us to study the kidney biopsy tissues (collected for medical reasons) after the regular routine studies have been completed. Through our special research measurements and additional study, we hope to be able to see and measure very specific changes in the kidney tissues from Fabry patients taking ERT. We also hope that through these studies of what happens within the kidney before and after starting ERT, we are able to reveal valuable information about the importance of factors like your age that you started ERT, the amount or dosage of ERT, and any differences seen between males and females.

We are studying a new phone app, UrApp, for parents (or caregivers) to use when managing the care of children who have been diagnosed with nephrotic syndrome in the last six weeks. We will look at medication and urine monitoring with two groups; one will use the app, the other will have usual care. Study participation will last for one year.
