NCT ID: NCT04494438 Completed - Clinical trials for Idiopathic Nephrotic Syndrome

Rituximab for Idiopathic Nephrotic Syndrome

Start date: July 2013
Phase: Phase 3
Study type: Interventional

Open-label, randomized, controlled trial due to value whether the monoclonal antibody rituximab is non-inferior to steroids in maintaining remission in juvenile forms of SDNS. The investigators will enroll 30 pediatric patients affected by idiopathic nephrotic syndrome, who have been in treatment with steroids for at least one year. The lowest dose of drug required to maintain a stable remission will be between 0.4 and 0.7 mg/ kg/ day. This trial provides an initial run-in phase of one month during wich remission will be achieved by means of a standard oral prednisone course. Once remission has been achieved children will be randomized in a parallel arm open label RCT to continue prednisone alone for one month (control) or to add a single intravenous infusion of rituximab (375 mg/m2 - intervention). Prednisone will be tapered in both arms after one month.

NCT ID: NCT04169776 Completed - Clinical trials for Idiopathic Nephrotic Syndrome

Effect of Daily Transcutaneous Auricular Vagus Nerve Stimulation (taVNS) on Proteinuria in Pediatric Patients With Idiopathic Nephrotic Syndrome

taVNS
Start date: December 1, 2019
Phase: N/A
Study type: Interventional

This study evaluates the impact of transcutaneous auricular Vagus Nerve stimulation (taVNS) therapy on the incidence of nephrotic syndrome relapses in children with idiopathic nephrotic syndrome. Participants will perform taVNS 5 minutes a day for 6 months total, monitoring for signs of nephrotic syndrome relapse with both labwork and clinical symptoms.

NCT ID: NCT04034316 Completed - Clinical trials for Nephrotic Syndrome in Children

Reduce Immunosuppression With Atmp in NS ChildrEn

RACE
Start date: November 2, 2018
Phase: Phase 2
Study type: Interventional

A phase II open-label, single arm study aimed to ascertain whether infusions of cord-blood mesenchymal stromal cells (CB-MSCs) allow to reduce or suspend the chronic immunosuppressive therapy (IS) in steroid-dependent nephrotic syndrome (SDNS). We plan to enroll 11 patients aged 3 to 18 with SDNS in remission for at least one month, maintained by either ≥2 immunosuppressive drugs or a calcineurin inhibitor. Patients are infused with cord-blood allogenic MSC, selected by in-vitro alloreactivity, at a dose of 1.5x10^6/kg on days 0, 14, 21. The immunosuppressive treatment is gradually tapered starting at the first CB-MSC administration, according to the following scheme: 25% following the first administration, 50% following the second administration, and 100% reduction following the third administration. All patients will be followed-up for 6 months from the last CB-MSC. Study visits are planned at baseline during CB-MSC administrations, 2 weeks (follow-up [FU]1) and 6 weeks (FU2) after the last infusion, and then every 6 weeks. During follow-up, the patients undergo a physical examination (including measurement of height, weight and blood pressure) and laboratory evaluations (urinary protein:urinary creatinine ratio, complete blood count, kidney function, plasma proteins, liver function, triglycerides and cholesterol). In addition, a blood sample is taken for regulatory T lymphocyte quantification, a marker of clinical response to the infusions.

NCT ID: NCT01609426 Completed - Clinical trials for Idiopathic Nephrotic Syndrome

Factors of Steroid Dependency in Idiopathic Nephrotic Syndrome

NEPHROVIR-2
Start date: September 2012
Phase: N/A
Study type: Observational

The primary purpose of the study is to identify the factors of steroid dependency in childhood idiopathic nephrotic syndrome. The steroid dependency is defined by a relapse of nephrotic syndrome within the 3 weeks that follow the withdrawal of steroid therapy after the first manifestation. Different clinical and biological factors will be analyzed: age of first manifestation, delay of remission, ethnicity, and preceding viral infection, geolocalization in the Parisian area, genoprevalence of herpes viruses and polymorphisms in the genes involved in the response to steroid therapy.

Cyclophosphamide Versus Mycophenolate Mofetil for the Treatment of Steroid-dependent Nephrotic Syndrome in Children

NEPHROMYCY
Start date: September 2010
Phase: Phase 3
Study type: Interventional

Idiopathic nephrotic syndrome is steroid-sensitive in more than 90% of cases in children. However 60% of cases are steroid dependent and required treatment with immunosuppressive agent. Cyclophosphamide and ciclosporin are used for long time to reduce steroid dependency, but duration of these treatments should be restricted because of gonadotoxicity for cyclophosphamide and nephrotoxicity for ciclosporin. Mycophenolate mofetil appears as an alternative treatment without gonadotoxicity and nephrotoxicity. However, contrary to cyclophosphamide, mycophenolate mofetil does not seem to have a residual action so that treatment must be maintained during months or years. The aim of the study is to compare efficacy of cyclophosphamide and mycophenolate mofetil in steroid dependent nephrotic syndrome in children.

NCT ID: NCT00255398 Completed - Kidney Disease Clinical Trials

Kidney Disease Biomarkers

Start date: November 10, 2005
Phase:
Study type: Observational

Kidney Disease Biomarkers Summary: This study will identify biomarkers (proteins and other molecules in the blood or urine) that may help scientists predict what kidney disease a patient has and whether a given patient would respond to particular therapies. The study will look for biomarkers in the blood and urine of patients with various kidney diseases and study of the effects of angiotensin converting enzyme inhibitors (ACE inhibitors) and angiotensin receptor blockers (ARB) on biomarkers. Blood and urine from healthy volunteers will be studied for comparison. Healthy people and the following patients may be eligible for this study: adults with diabetic nephropathy 18 years of age and older; children with newly diagnosed clinical idiopathic nephrotic syndrome between 2 and 18 year of age; children and adults with glomerular disease (minimal change disease, focal segmental glomerulosclerosis, or collapsing glomerulopathy). Participants undergo tests and procedures as follows: Glomerular Disease: Adults with glomerular disease provide about four to six blood and urine samples over the course of 6 to 12 months. The samples are collected at the time of regularly scheduled visits for the NIH treatment protocol in which they are participating. Children provide only blood samples. Chronic Kidney Disease: Patients with chronic kidney disease provide a blood and urine sample every 6 months for 3 years or more. Angiotensin Antagonism: Patients with chronic kidney disease who are taking ACE inhibitors or ARBs stop their medicines for 4 weeks, while those who are not taking ACE inhibitors or ARBs begin one of the medicines. In general, patients just starting on the medications continue them after the study is completed, since they are beneficial for chronic kidney disease. - Medication withdrawal group: Patients come to NIH for 2 successive days at the beginning of the study for blood and urine tests (including one 24-hour urine collection) and to receive iothalamate (a chemical used to measure kidney function). Iothalamate is delivered over 24 hours through a needle placed in the abdomen (or elsewhere) via a pump similar to pumps that some diabetics use to deliver insulin. Patients then stop taking their ACE inhibitor or ARB medication. They monitor their blood pressure every day and return to NIH after 1, 2 and 4 weeks for blood tests. During week 4, the iothalamate infusion is repeated, and blood and urine samples are collected as at the beginning of the study. Patients then resume taking their ACE inhibitor or ARB once a day with the dose being increased at 2-week intervals. They come to NIH weekly after 1 week and then every other week for blood tests. Four weeks after reaching the highest FDA-recommended dose of medication tolerated, the iothalamate infusion and blood and urine collections are repeated. - Medication induction group: At the beginning of the study, patients have the iothalamate infusion and blood and urine collections described above and then begin to take either an ACE inhibitor or ARB. The dose is increased after 2 weeks. Patients monitor their blood pressure every day. After being on the highest dose for 4 weeks, patients repeat the iothalamate infusion and blood and urine collections. The study is then complete and they are provided a 2-month supply of medicine to take home. Information is gathered on symptoms, treatments, and results of past laboratory tests of all patients. Healthy volunteers provide blood and urine sample collections every month or every other month for up to four collections to be used for biomarker studies and the screen for common chronic diseases.
