Active clinical trials for "Glomerulonephritis"

The primary aim of this study is to extend follow up of TESTING study participants and to assess the long-term effects of a 6-9-month course of oral methylprednisolone on End Stage Kidney Disease (ESKD), according to dose (full-dose vs reduced-dose), ethnicity (Chinese vs other) and kidney function (eGFR above and below 60 mL/min/1.73m2).

This protocol is part of a larger project, COMPRare (COMPlement-mediated Rare kidney diseases), which has been financed on behalf of the EJP RD (European Joint Programme on Rare Diseases) program of EU and is leaded by a scientific consortium from 7 European countries. The partners (P) of the consortium are: P1. Radboudumc Amalia Children's Hospital (The Netherlands) P2. Semmelweis University (Hungary) P3. Cordeliers Research Center (France) P4. Max Delbruck Center for Molecular Medicine (Germany) P5. Istituto di Ricerche Farmacologiche Mario Negri (Italy) P6. Lund University (Sweden) P7. Lille University (France) The general aim of the project is to define new diagnostic tools for complement activation in order to improve patients stratification and follow-up, thereby affecting time and choice of treatment in patients with aHUS and C3G. Particularly, the specific objectives of the COMPRare are: To develop new standardized analytic assays thereby identifying specific complement prognostic biomarkers for early diagnosis, classification, improved monitoring and treatment of patients with aHUS and C3G; To in-depth characterize patients' complement abnormalities in blood, in patient-derived cells and in kidney biopsies; To identify strategies to classify VUS/LPV To find new pathophysiological pathways involved in aHUS and C3G for further improving disease diagnosis, monitoring and treatment. The results of these studies will form the basis of personalized treatment with existing and upcoming complement inhibitory drugs for these rare complement-mediated kidney diseases.

This project aims to identify, through RNA-Seq technology, the genetic alterations underlying undiagnosed rare diseases in pediatric and adult patients with early onset and with negative WES. Objective 1: Set up and validate techniques. Set-up and validation of the transcriptome analysis protocol in healthy subjects and in patients with known splicing alterations and/or altered RNA expression. Objective 2: Diagnostic phase. Study of splicing alterations and RNA levels in cultured fibroblasts obtained from skin biopsies of patients with rare genetic diseases and negative exome. Exploratory goals Compare the RNA expression profile obtained from skin biopsy-derived fibroblasts with the RNA expression profile from blood. The most relevant results will be validated in qRT-PCR. To analyze the transcriptional and protein profile heterogeneity in skin-derived fibroblasts in enrolled subjects. To explore the effects of genetic (from WES) and transcriptional (from RNA-seq) alterations in participants' plasma and serum. Healthy controls Five healthy subjects will be recruited from the staff of the Mario Negri Institute for Pharmacological Research. The coded samples will be used to set up the method of isolation and culture of skin fibroblasts and RNA-Seq. Validation group For the set-up and validation of the skin fibroblast isolation and RNA-Seq procedure, ten adult patients with known diagnosis and with alterations in RNA levels and/or splicing will be recruited as positive controls. Patients who meet the requirements described above will be contacted by the doctors of the Daccò Center for an interview explaining the project. Those who agree to participate in the study will be asked to sign the informed consent before proceeding with the experimental part. "Discovery/Exploration" group The exploration cohort will be composed of 30 symptomatic undiagnosed patients with suspected genetic disease (children and adults with infantile onset) belonging to the Clinical Center of the Mario Negri Institute for Pharmacological Research and for whom WES investigations did not reveal causative genetic alterations.

Glomerulonephritis (GN) generates an enormous individual and social economic burden. However, the therapeutic options are largely based on clinical and pathological parameters and the individual response to therapy or prognosis is uncertain. Recently, along with advances in molecular analysis and computational bioinformatics, genomic data from human renal biopsies could provide a strong foundation for the future of precision medicine in nephrology. In response to a request for applications by the Ministry of Health and Welfare of Korea for the creation of Clinical Research Registry, multi-center N network has been established for prospective cohort with kidney biopsy samples (KORNERSTONE). Through this Network the investigators hope to understand the fundamental biology of glomerulonephritis and aim to bank long-term observational data and corresponding biological data including genomic data from kidney tissues, and kidney pathologic data which is digitalized This database is archived to a web-based platform to access easily and further enrich for researchers.

This study will investigate the ability of renal MRI to detect fibrosis, how this correlates to renal function and how well renal MRI biomarkers can predict decline in kidney function over time. We will also assess the correlation of renal MRI and kidney function to markers of renal ageing in blood, urine and tissue samples.

Urinary T lymphocytes may be predictive for clinical outcome in patients with ANCA associated glomerulonephritis (ANCA GN). The investigators hypothesize that the amount of CD4+ effector/memory T cells in urine at time of diagnosis predicts the outcome of patients with active ANCA GN after 6 months of therapy. In a prospective, six-months follow-up study patients' urine will be analysed by flow cytometry every 60 days (+/- 10d). Treatment will be performed to the discretion of the treating clinician. After 6 months of treatment response will be determined as either complete response or partial response.

This is a phase 2a study evaluating the safety and tolerability of multiple ascending doses of GFB-887 in patients with diabetic nephropathy (DN), focal segmental glomerulosclerosis (FSGS), and treatment-resistant minimal change disease (TR-MCD).

This is a randomized, open-label, two arm, parallel group, proof-of-concept, non-confirmatory study evaluating the efficacy and safety of LNP023 compared with rituximab in subjects with membranous nephropathy (MN) who are at high risk of disease progression defined on the basis of antibody anti-PLA2R titre and proteinuria.

Crescentic IgA nephropathy (CreIgAN) has a poor prognosis despite aggressive immunosuppressive therapy. The efficacy of plasma exchange (PE) in CreIgAN is not well defined. This study will evaluate the efficacy and safety of plasma exchange as adjunctive therapy for severe crescentic IgA nephropathy compared to pulse methylprednisolone on a background of oral prednisolone and cyclophosphamide in prevent kidney failure.

Primary Hypothesis: Aldosterone breakthrough will occur at a far lower frequency during renin inhibition (0-10% over 9 months), alone or in combination with an ARB, compared to conventional ARB therapy (35-45% over 9 months). The investigators hypothesize that aldosterone breakthrough occurs due to accumulation of active precursor substances, most notably angiotensin II, produced in response to conventional RAAS blockade with ACEinhibitors and ARBs. The investigators believe that direct renin inhibition (DRI) should minimize this accumulation and therefore significantly lower or possibly eliminate the breakthrough effect. Interruption of the renin-angiotensin-aldosterone system (RAAS) with angiotensin-converting enzyme inhibitors (ACE-Is) and angiotensin receptor blockers (ARBs), alone and in combination, has become a leading therapy to slow the progression of chronic heart and kidney disease. Both types of drugs inhibit the formation of aldosterone, a hormone, which has been shown to have harmful effects on patients with chronic heart and kidney disorders. This treatment is effective but not perfect since, even after an initial improvement, many patients become worse over the long term. This may be due to an unexpected increase in aldosterone, a phenomenon called "aldosterone breakthrough." The purpose of this study is to find out whether the use of a direct renin inhibitor (DRI) alone, or in combination with an angiotensin receptor blocker (ARB), will lessen the occurrence of aldosterone breakthrough since direct renin inhibitors inhibit the formation of aldosterone at a very early step. This study will compare the effectiveness of adding Diovan (valsartan) or Tekturna (aliskiren) or a combination of Diovan and Tekturna to the usual antihypertensive treatment. The investigators will follow blood pressure, aldosterone levels, and urinary protein levels over 9 months to evaluate which of these therapies is most effective for treating hypertension in patients with proteinuric kidney disease.
