Multitarget Therapy for Idiopathic Membranous Nephropathy
EfficacyMembranous nephropathy (MN) is one of the commonest causes of nephrotic syndrome in adults, idiopathic membranous nephropathy (IMN) accounts for 70%-80% of all MN patients. There is no standard specific treatment for IMN. Initial therapy should be supportive and involves restricting dietary protein and sodium intake, controlling blood pressure, hyperlipidemia, and edema. The best proven therapy for patients with IMN is combined use of corticosteroids and cyclophosphamide. However, there are some potential risk of other serious side effects associated with the use of cytotoxic agents, such as bone marrow toxicity, severe infections, gonadal dysfunction, and the long-term risk of malignancy. The ideal maintenance treatment scheme for patients with IMN requires not only a remission of nephrotic syndrome but also, fewer adverse effects. Some retrospective study suggested that multitarget therapy (prednisone+calcineurin inhibitors+mycophenolate mofetil) was effective for refractory IMN. However, we cannot get confirmed conclusion from the previous study due to the limitation of retrospective studies with small sample size. In this prospective multicenter randomized trial, we compared the efficacy between multitarget therapy and Ponticelli regimen. Trial Aims and Hypothesis The specific aims of this trial are to test the hypothesis that multitarget therapy is non-inferior to Ponticelli regimen in inducing long-term remission (CR or PR) of proteinuria in patients with IMN. that multitarget therapy reduces the number of relapses (efficacy in sustaining remission) and increases the time to relapse when compared with treatment with Ponticelli regimen. that multitarget therapy has a better side-effect profile when compared with treatment with Ponticelli regimen in patients with IMN. Methods: Patient Recruitment Inclusion and exclusion criteria are as follows. Inclusion Criteria: Age: 18-70 years. Body weight: 50-90 kg. Patients with membranous nephropathy were eligible if their diagnosis was confirmed by renal biopsy, with the biopsy sample examined by light, immunofluorescence, and electron microscopy. Renal biopsy samples were reviewed by the two principal investigators and two renal pathologists. IMN patients with moderate risk and have a decline of less than 50% in proteinuria despite renin-angiotensin system blockade for at least 6 months before randomization. OR, IMN patients with high risk or very high risk. Serum albumin < 30 g/L. eGFR by MDRD formula had to be ≥ 60 ml/min per 1.73 m2. Exclusion criteria: Secondary MN, pregnancy, breastfeeding, immunosuppressive treatment in the 3 preceding months, and active infectious disease. Hepatitis B serology included Hbs antigen and Hbs and Hbc antibodies. Patients with active hepatitis B and those with past hepatitis B infection without anti-Hbs antibodies will be excluded. Patients with reproductive demand will be excluded. Randomization and Treatment Groups Once all entry criteria have been satisfied and confirmed, patients will be randomized to treatment with multitarget therapy or Ponticelli regimen. Multitarget therapy: Combination with prednisone, ciclosporin and mycophenolate mofetil. Ponticelli regimen: Cyclical corticosteroid/alkylating-agent therapy for IMN. Outcomes Primary outcome: The primary clinical outcome was the composite of complete or partial remission at 12 months. Secondary outcome: the composite of complete or partial remission at 6 months; complete remission at 6 months; and adverse events, relapse.
Prognostic Model of GC/TAC in the Treatment of MN
Idiopathic Membranous NephropathyThe goal of this observational study is to explore the factors that can predict the prognosis difference in patients with idiopathic membranous nephropathy (IMN) under the treatment of glucocorticoid + tacrolimus. The main questions it aims to answer are: to explore the factors that can predict the prognosis difference in patients with IMN under the treatment of glucocorticoid + tacrolimus to establish a clinical prediction model and verify it to provide a reference for the early Participants will receive standard the treatment of glucocorticoid + tacrolimus treatment and will then be divided into remission and non remission groups based on the treatment effect after the standard treatment cycle. Blood, urine, and fecal samples were collected from patients to explore possible factors influencing treatment efficacy. Researchers will compare [remission group and non-remission group] to see if the gut microbiota and its metabolites are factors that influence the efficacy of treatment.

Dose-Finding Pilot Study of ACTH in Patients With Idiopathic Membranous Nephropathy
Idiopathic Membranous NephropathyThis pilot study is aimed at demonstrating the effectiveness of ACTH (H.P. Acthar Gel) on the lipid profile and proteinuria in participants with MN. ACTH or adrenocorticotrophin is a hormone produced by the pituitary gland (a gland at the base of your brain) that is involved in stimulating your adrenal glands to secrete a number of steroid products (e.g. cortisol, aldosterone, corticosterone, and others) that are important in keeping you alive. The drug used in this study has been approved by the Food and Drug Administration (FDA) for routine clinical use in the treatment of patients with proteinuria and patients with idiopathic nephrotic syndrome such as idiopathic MN. However, the most adequate dose to use has not been adequately assessed. This is the reason for conducting this research study.
A Dose Escalation Study of Long-acting ACTH Gel in Membranous Nephropathy
GlomerulonephritisMembranous Nephropathy (MN) is an immune-mediated kidney disease that affects the glomerulus or the filter that removes toxins from the blood. Damage to the membrane that separates blood from urine results in loss of protein into the urine (proteinuria) and in some cases loss of kidney function.There is no standard specific treatment for MN. ACTH has a pronounced lipid-lowering effect in healthy individuals, in steroid-treated patients with renal disease and in hemodialysis patients Some studies suggest that prolonged synthetic ACTH therapy may represent an effective therapy in patients with idiopathic MN, more extensive randomized studies with longer follow-up are needed before therapeutic recommendations can be made. We propose to do a pilot study to test the hypothesis that biologic ACTH, a slow-release formulation of corticotropin extracted from porcine pituitary glands (H.P. Acthar gel) will be effective in reducing proteinuria and improving lipid profile in patients with idiopathic MN.

Tacrolimus Treatment of Patients With Idiopathic Membranous Nephropathy
Idiopathic Membranous NephropathyThe purpose of this study is: To explore the potential role of tacrolimus in the treatment of membranous nephropathy. To investigate the safety and tolerability of tacrolimus vs methylprednisolone plus cyclophosphamide.
Mycophenolate Mofetil in Membranous Nephropathy
GlomerulonephritisMembranousPatients with idiopathic membranous nephropathy and renal insufficiency are at risk for end-stage renal disease (ESRD). Treatment with cyclophosphamide is currently used as a treatment modality. Mycophenolate mofetil is a new immunosuppressive agent with fewer side effects. In this pilot study patients with membranous nephropathy and renal failure will be treated with mycophenolate mofetil and prednisone. The outcome will be compared with historical controls treated with a similar regimen containing cyclophosphamide.
A Prospective Multi-dose Study of Apixaban in Subjects With Nephrotic Syndrome
Nephrotic SyndromeMembranous NephropathyThis phase I study is a single arm, multi-dose study that will evaluate steady-state apixaban pharmacokinetics (PK) and pharmacodynamics (PD) in subjects with Nephrotic Syndrome (NS) vs healthy control subjects. This study will enroll 20 subjects diagnosed with NS and 10 healthy control subjects. Comparing differences in steady-state apixaban PK/PD parameters between subjects with NS and healthy volunteers will be essential to identifying a safe and effective apixaban dose and dose administration schedule for future randomized controlled trials (RCTs).
A Study of Belimumab in Idiopathic Membranous Glomerulonephropathy
GlomerulonephritisMembranousThis is a phase II, open label, experimental medicine study to evaluate the efficacy, safety and mechanism of action of belimumab in subjects with antiphospholipase A2 receptor (PLA2R) autoantibody positive idiopathic membranous glomerulonephropathy (IMGN), and to profile the relationship between biomarkers, autoantibody status and clinical response. 10 milligrams per kilogram (mg/kg) belimumab intravenous (IV) will be administered at weeks 0, 2, and then every 4 weeks, over a 24-week treatment period in subjects with anti-PLA2R antibody positive IMGN followed by a further long term treatment period until subjects reach remission of proteinuria, up to a maximum of 2 years total treatment. All subjects will receive background supportive therapy throughout the study. The dosing frequency will be adjusted to every 2 weeks if the subject's proteinuria as assessed by urinary protein creatinine ratio (PCR) is greater than 1000 milligrams per millimole (mg/mmol) [greater than 10 grams(g)/24 hours (h)], to compensate for loss of belimumab in the urine. Effects on mechanistic markers will be measured by the level of proteinuria, levels of anti-PLA2R antibodies, and various other measures of kidney function. These will be compared to historical data. The pharmacokinetics of belimumab will be measured to confirm dosing in heavily proteinuric subjects. Pharmacodynamic (PD) markers, biomarkers and Quality of Life(QoL) in IMGN subjects will also be investigated. Safety will be assessed by adverse events (AE), clinical laboratory evaluations, and vital signs.
