Evaluate Rituximab Treatment for Idiopathic Membranous Nephropathy

Idiopathic Membranous Nephropathy

The Membranous Nephropathy is one of the most common cause of Nephrotic Syndrome of adults. In 2/3 of patients the cause of the disease is idiopathic. This can also be referred to as idiopathic membranous nephropathy (IMN).The most of these patients are treated by non immunosuppressive symptomatic treatment (NIST): antiproteinuric and antihypertensive blocking the rennin-angiotensine system. However, the patients resistant to antiproteinuric treatment risk to develop an end stage renal disease (ESRD). Rituximab has been recently used in patients suffering of nephrotic syndrome related to IMN in four international studies. Rituximab appears effective and safe in reducing proteinuria in nearly 60% of patients. The primary outcome of the investigators prospective randomized study is to determine whether or not the Rituximab associated with NIST is more effective than non immunologic symptomatic treatment alone in inducing long term remission of proteinuria.

Acthar for Treatment of Proteinuria in Membranous Nephropathy Patients

ProteinuriaIdiopathic Membranous Nephropathy

The purpose of this study is to provide nephrologists with additional clinical evidence regarding the efficacy and safety of Acthar in subjects with treatment-resistant idiopathic membranous nephropathy. Approximately sixty (60) subjects will be randomized in this double-blind, parallel-group, placebo-controlled, multicenter study comparing Acthar and Placebo administered 2 times per week for a 24-week treatment period followed by a 24-week observation period. The primary objective of this study is to assess the proportion of treatment-resistant subjects (defined as subjects who either have had no response or have suffered a relapse after achieving a partial response to their most recent standard treatment regimen) who have a complete or partial remission of proteinuria in nephrotic syndrome due to idiopathic membranous nephropathy after 24 weeks of treatment.

Rituximab in Membranous Nephropathy

Membranous Nephropathy

Membranous glomerulopathy (MN) is a common immune-mediated glomerular disease and the leading cause of nephrotic syndrome in Caucasian adults. 1 Because of its frequency, it remains the second or third cause of end-stage renal disease caused by a primary glomerulonephritis. 2 At presentation, 70% to 80% of patients have the nephrotic syndrome. 1, 3, 4 Proteinuria greater than 2.0 grams per day is found in > 80% of patients at presentation, with greater than 10 grams found in as many as 30%. 5 The disease affects patients of all ages, but it is most often diagnosed in middle age with the peak incidence during the fourth and fifth decades of life. There is close to a two-to-one predominance of males to females diagnosed with the disease. Idiopathic MN affects all races. Current therapeutic options include corticosteroids alone or in combination with alkylating agents, cyclosporin A, and mycophenolate mofetil. The most widely recognized, and best-validated regimen is combination therapy with corticosteroids and an alkylating agent, but its use is associated with significant adverse effects. Recent meta-analysis confirmed that present day treatments are far from ideal 6 Thus, it should not come as a surprise that the outcome of MN has not substantially improved over the past 30 years, and up to 40% of patients still progress to end-stage renal failure. 7 Like in other glomerular diseases the amount of protein in the urine correlates well with long term prognosis. Thus, this parameter has been used in previous studies, and will be used in this study, as the primary indicator of effectiveness of therapy. We proposed to do a pilot study to test the hypothesis that selective B lymphocyte depletion will result in disappearance of pathogenic antibodies and induction of remission of the nephrotic syndrome in patients with idiopathic membranous nephropathy. Our population will be 10 adults. The study will be conducted between our Nephrology Divisions at Mayo Clinic Rochester, Jacksonville, and Scottsdale. We will enroll patients with a GFR 25 ml/min as estimated by creatinine clearance and proteinuria > 4g/24h, while receiving an ACEI or ARB and with BP controlled of < 130/80 mmHg. Patients will receive Rituximab 1g on Day 1 and 15. Patients followed for 1 years following completion of treatment. The primary outcome will be change in urinary protein excretion at 6 months. Secondary outcomes will be changes in serum albumin, serum lipid?s profile, the number of partial remissions, time to remission, and incidence of relapses. We will also perform a pharmacokinetic study to evaluate the effect of proteinuria on the bio-availability and effects of the drug.

Mycophenolate Mofetil in Membranous Nephropathy and Focal Segmental

GlomerulonephritisMembranous2 more

This is a prospective randomized open-label pilot study to investigate the effect of mycophenolate mofetil treatment in patients with abnormal urine protein excretion due to membranous nephropathy (MN) or focal segmental glomerulosclerosis (FSGS). The change in urine protein excretion will be the primary outcome studied. The treatment regimen comprising prednisolone and mycophenolate mofetil will be compared with prednisolone and chlorambucil in MN, and compared with prednisolone in FSGS. The study duration will be 12 months for each patient.

Sirolimus Therapy for Idiopathic and Lupus Membranous Nephropathy

Membranous GlomerulonephritisLupus Membranous Nepropathy

This study will evaluate the safety and effectiveness of a new immunosuppressive drug, sirolimus, in reducing the amount of protein in the urine in patients with membranous nephropathy. This condition involves damage to the walls of tiny blood vessel filters in the kidneys called glomeruli, which allows blood proteins to leak into the urine. Patients have low blood protein levels and high blood cholesterol. Some patients may have leg swelling, impaired kidney function, blood vessel and heart disease, and a risk of emboli (blood clots that travel to the lungs). Drugs currently used to treat membranous nephropathy vary in their effectiveness among patients and can cause severe side effects. The Food and Drug Administration has approved sirolimus for suppressing the immune system of patients who have had a kidney transplant to reduce the risk of organ rejection. The drug does not have certain side effects that have caused problems for patients treated with other immunosuppressants, such as: prednisone (weight gain, round face, diabetes, weak and fractured bones, and cataracts); cyclophosphamide (fertility problems, bladder injury and bladder cancer, and other cancers); chlorambucil (fertility problems, seizures, acute leukemia, and other cancers); and cyclosporine (kidney toxicity, increased facial hair, and seizures). Patients 13 years of age or older with idiopathic membranous nephropathy or lupus membranous nephropathy may be eligible for this study. Candidates must have completed at least one month of treatment with a stable dose of angiotensin converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs). They will be screened with a medical history, physical examination, blood tests, skin test for exposure to tuberculosis, and an examination for infection, cancers, and other conditions that can cause membranous nephropathy. Participants will take sirolimus once a day for 1 year, except for the first day of treatment, when they will take three doses to quickly bring their blood levels of the drug up to a therapeutic level. They will undergo evaluations at the NIH in Bethesda, Maryland, at baseline (before starting treatment) and again at 1- to 4-month intervals during the study. In addition, they will have blood tests every week for the first month and every 2 weeks for the second month; then blood and urine tests once a month for the next 10 months of treatment and then every 4 months for a 12-month period after treatment stops. These tests will evaluate drug side effects and the response to therapy, and will determine if the therapeutic benefits persist long-term when treatment stops. Patients will also be asked to have optional kidney function tests during the baseline evaluation and at the end of the follow-up period to measure kidney filtration and blood flow rates. Those who participate will be given fluids and other substances by vein to accurately measure kidney function. They will then have blood and urine samples collected about four times over a 1-hour period after drinking fluids to increase urine output. Patients who experience a substantial increase in proteinuria or substantial decrease in kidney function during the course of treatment will stop taking sirolimus and be taken off the study.

Efficacy and Safety Study of Intravenous Belimumab Versus Placebo in Subjects With Idiopathic Membranous...

GlomerulonephritisMembranous

The main clinical study will be a randomized, double-blind, placebo-controlled, long term study involving a 100 week treatment period. The purpose of this study is to test for superiority of treatment with belimumab 10 mg/kg plus supportive therapy compared to placebo plus supportive therapy in idiopathic membranous nephropathy (IMN). The purpose of this study is also to investigate the effect of initiating earlier treatment with belimumab compared to delayed treatment with current immunosuppressive treatment regimens. The study will also determine the pharmacokinetic (PK) profile of belimumab and further explore the mechanism of action of Belimumab as well as effects on quality of life. All subjects (on either active treatment or placebo) will receive background supportive therapy throughout the main clinical study, which includes angiotensin-converting enzyme inhibitors (ACEi) and/or angiotensin receptor blockers (ARBs) unless contraindicated and may include statins, diuretics, dietary salt restriction but excludes immunosuppressants (except low dose corticosteroids). Screening will be done within 5 to 2 weeks before the first scheduled dose of study treatment. A total of 94 evaluable subjects will be randomized in a 1:1 ratio such that 47 subjects receive intravenous belimumab 10 mg/kg and 47 receive intravenous placebo. Subjects will be dosed on Days 0, 14, 28 and then every 4 weeks through to, and including, Week 100, resulting in a total of 27 doses (giving 104 weeks of drug exposure). 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 1000mg/mmol (greater than 10 g/24 h), to compensate for loss of belimumab in the urine. Subjects who are withdrawn from study treatment at any time during the study, eg for rescue therapy, will participate in follow-up visits every 12 weeks up to week 104. A subject will be regarded as having completed the main clinical study if they complete all phases of the main clinical study (screening, treatment period, 4 week and 16 week post last dose short term safety follow-up). Subjects who complete the main clinical study will therefore participate in the main clinical study for approximately 28 months. After the main clinical study, there will be a 5 year (long term) follow-up phase to assess long term outcomes.
