NCT ID: NCT03929887 Recruiting - Lupus Nephritis Clinical Trials

KOrea Renal Biobank NEtwoRk System TOward NExt-generation Analysis

KORNERSTONE
Start date: May 1, 2019
Phase:
Study type: Observational [Patient Registry]

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.

Study type: Interventional

The overall aim of the study is to evaluate the efficacy, safety, and tolerability of Nefecon 16 mg per day in the treatment of patients with primary IgAN (Immunoglobulin A nephropathy) at risk of progressing to end-stage renal disease (ESRD), despite maximum tolerated treatment with renin-angiotensin system (RAS) blockade using angiotensin converting enzyme inhibitors (ACEIs) or angiotensin II type I receptor blockers (ARBs).

NCT ID: NCT03633864 Recruiting - IgA Nephropathy Clinical Trials

Fecal Microbiota Transplantation for Refractory IgA Nephropathy

Start date: November 22, 2017
Phase: Phase 2
Study type: Interventional

IgA nephropathy (IgAN) is one of the most common glomerular diseases worldwide. Current treatments for IgAN are limited by their relatively insufficient efficacy and severe adverse events. Previous studies suggested that the disorder of intestinal flora may play an important role in the pathogenesis and prognosis of IgAN. Fecal microbiota transplantation (FMT) have been proved to be effective on rebuilding the intestinal microecological balance. However, there is no evidence for the safety and efficacy of FMT in IgAN. Therefore, investigators perform a prospective cohort study to evaluate the safety and efficacy of FMT in IgAN patients who did not response to the conventional treatment and did not want to aggravate immunosuppressive treatments or IgAN patients who did not response to immunosuppressive treatments.

NCT ID: NCT03608033 Terminated - IgA Nephropathy Clinical Trials

NCT ID: NCT03488368 Completed - IgA Nephropathy Clinical Trials

Longterm Renal Oucomes of STOP-IgAN Trial Participants

Start date: February 1, 2018
Phase:
Study type: Observational

IgA nephropathy (IgAN) is the most prevalent form of primary glomerulonephritis in the Western world. Although most IgAN patients take a benign longterm course, about 20-30% progress to end-stage renal disease (ESRD) over 20 years. The majority of current treatment recommendations is based on weak evidence. In the randomized, controlled Supportive Versus Immunosuppressive Therapy for the Treatment Of Progressive IgAN (STOP-IgAN) trial, the investigators analyzed whether additional immunosuppression on top of standardized supportive care provides renal benefits in patients with progressive IgAN. Patients with persisting proteinuria >0.75 g/d (n=162) despite optimized supportive treatment including control of blood pressure and proteinuria, were randomized to either continue on supportive care or to receive additional immunosuppression during the 3-year trial phase. It was observed that immunosuppressive therapy in addition to optimized supportive care led to more full clinical remissions, but eventually did not better preserve renal function, did not better save patients from ESRD development and evoked more adverse effects such as infections, weight gain and diabetes. Aim of this planned study is to analyze renal outcome measures and adverse effects in the longterm observation of all randomized STOP-IgAN participants to ascertain quality and strength of the original trial results. By its observational nature, this quality control study includes the 162 IgAN patients (with the exception of drop-out patients) that had been previously randomized into the original STOP-IgAN trial. Information on serum creatinine, proteinuria, ESRD, death, relevant adverse events such as major cardiovascular events, osteoporosis, osteonecrosis, bone fractures, diabetes, malignancies and interim treatment will be collected as available from existing routine records until March 31, 2018. Primary endpoint is the time to the first occurring event of the binary composite of all-cause death, ESRD or decline in estimated glomerular filtration rate (eGFR) by at least 40% as compared to enrollment into the original trial. Secondary outcome measures comprise the individual components of the primary endpoint, absolute eGFR at the end of observation, proteinuria and adverse events. Information on specific treatments with renin-angiotensin-system (RAS)-blocking agents and/or interim immunosuppression will also be collected. All data will be recorded in a pseudonymous fashion in a central electronic data base located at the PI's site.

NCT ID: NCT03468972 Not yet recruiting - Clinical trials for Biopsy-proven IgA Nephropathy

Effect of Immunosuppression in IgA Nephropathy

Start date: March 2019
Phase: Phase 4
Study type: Interventional

IgA nephropathy (IgAN) is the most common glomerulonephritis worldwide, leading to end stage renal disease (ESRD) in up to 30 to 40% of patients with in a few decades after diagnosis. Several therapeutic options have been used in clinical practice. However, no treatments can completely stop the progression of IgAN. Given the pathogenic mechanism of IgAN, many researchers have tried to treat patients with IgAN using immunosuppression such as corticosteroids. To date, there have been conflicting results on the effects of immunosuppression in IgAN. Earlier studies from Italian groups showed that corticosteroid treatment significantly attenuated kidney function decline and decreased the development of ESRD. Since then, the beneficial effects of corticosteroids have generally been accepted for treatment of IgAN particularly in patients with high degree of proteinuria > 1.0 g/day despite maximal conservative care during 3 to 6 months. However, a recent interventional study by German group, known as the Supportive Versus Immunosuppressive Therapy for the Treatment of Progressive IgA Nephropathy (STOP-IgAN) trial, showed that immunosuppressive treatment in addition to intensive supportive care did not significantly improve renal outcome and resulted in more treatment-related side effects. Moreover, the Therapeutic Evaluation of Steroids in IgA Nephropathy Global (TESTING) study, another randomized controlled study from China, was early terminated because of safety concern related to corticosteroids. Interestingly, the primary composite outcome occurred significantly less in the methylprednisolone group as compared to the placebo group despite more serious adverse events in the former group. With this background in mind, we designed a multicenter prospective randomized controlled open-label trial; a step-wise therapeutic approach with corticosteroids or add-on cyclophosphamide therapy in IgAN patients with persistent proteinuria who have preserved eGFR of ≥ 30 ml/min/1.73 m2. A total of 19 hospitals will participate in this study. During 12 weeks before the enrollment, all patients will receive maximal supportive care including the use of RAS blockers, blood pressure control with a target of <130/80 mmHg, and protein restriction diet. If proteinuria does not decrease < 1.0 g/g creatinine, patients will be randomly assigned to continue supportive care, or to receive corticosteroids. At 3 months after randomization, patients in the corticosteroid arm who have persistent proteinuria of ≥ 1.0 g/g creatinine, or fast decline in eGFR ≥ 15% from the baseline value, will additionally receive cyclosphosphamide during the following 3 months. Patients who have substantial decreased amount of proteinuria < 1.0 g/g creatinine at 3 months will continue protocol-based corticosteroids during the same period. At 6 months after randomization, patients who receive add-on cyclophosphamide will switch to azathioprine as a maintenance therapy and those who receive corticosteroids alone will discontinue the treatment and will be followed up during 24 months thereafter. At least 87 subjects (a total of 174) would be required for each group to detect 13.5% difference in response rates between the two groups based on previous studies if type I error rate is 5% and type II error is 20% given 20% of drop-out rate during the study period. The primary endpoint is the development of a ≥ 30% decline in eGFR from the baseline or the onset of ESRD. This study will unveil conflicting results on the effects of immunosuppressive treatment in IgAN patients at high risk of progression.
