Dense Deposit DiseaseMembranoproliferative Glomerulonephritis Type II1 more

This study is evaluating the study drug (CDX-1135) in patients with dense deposit disease (DDD). The objective is to evaluate the safety and activity of repeated doses of CDX-1135 in pediatric and adult patients with DDD. After screening, eligible patients will be entered into the Induction Period. The Induction Period is up to 4 weeks. Following normalization of complement activity, patients will enter into the Maintenance Period.The total treatment duration is up to 26 weeks.

BG9588 (Anti-CD40L Antibody) to Treat Lupus Nephritis

GlomerulonephritisMembranoproliferative1 more

The purpose of this study is to investigate whether the experimental drug BG9588 can be used to treat lupus nephritis more effectively and with less toxicity than standard treatments, including cyclophosphamide (Cytoxan), azothioprine (Imuran) and prednisone. The body's immune system naturally produces antibodies to fight foreign substances like bacteria and viruses. In autoimmune diseases like lupus, however, the body makes antibodies that attack its own tissues, causing inflammation and organ damage. Lupus antibodies attack and damage kidney cells. BG9588 can interfere with the production of these antibodies, and therefore, may lessen kidney damage in people with lupus nephritis. This study will look at: how BG9588 enters and leaves the blood and body tissue over time; adverse effects of the drug; and whether treatment with BG9588 can result in less kidney damage than other therapies. Study patients will be receive a 30-minute infusion of BG9588 into a vein every two weeks for three doses and then once every 28 days for four doses. Patients' steroid dosage may be tapered; individual adjustments will be made as required. Patients screened for the study will undergo a physical examination, medical history, various blood and urine tests, as well as complete a quality of life questionnaire. Results of a previous kidney biopsy and chest X ray are also required. Many of these tests will be repeated throughout the study. In a previous animal study, BG9588 treatment of mice with lupus nephritis improved their disease and survival.

Eculizumab in Primary MPGN

Membranoproliferative Glomerulonephritis

Membranoproliferative glomerulonephritis (MPGN) is the third or fourth leading cause of end stage renal disease among the primary glomerulonephritis. Hyperactivation of the alternative complement pathway and familial forms for all types of MPGN have been reported suggesting that genetic abnormalities may play a predisposing role to the disease. In recent case reports Eculizumab, a monoclonal antibody that binds to C5 to prevent formation of the membrane attack complex ,is a safe and effective therapy.

Pilot Study of Rituximab for Membranoproliferative Glomerulonephritis

GlomerulonephritisMembranoproliferative

Membranoproliferative glomerulonephritis (MPGN) is a relatively-rare, immune-mediated kidney disease. All current therapies are inadequate and MPGN frequently leads to kidney failure. This study is a 10 patient trial of the monoclonal antibody rituximab for adult patients with MPGN. Study patients will receive 2 doses of rituximab intravenously on days 1 and 15 and will then be followed for 1 year.

Eculizumab Therapy for Dense Deposit Disease and C3 Nephropathy

Dense Deposit DiseaseMembranoproliferative Glomerulonephritis

This open label, non-blinded, proof of concept efficacy and safety study of eculizumab in patients with biopsy proven DDD or C3 nephropathy. The trial will consist of adult patients with these diseases who have > 1 gram of proteinuria or a decreased glomerular filtration rate (GFR), both predictors of a poor long-term outcome in many glomerular diseases. The patients will be treated with eculizumab for one year. The goals will be to determine whether treatment leads to an improvement in kidney function, defined by remissions of proteinuria and improvements in estimated GFR (measured by serum creatinine), and to improvement in histologic parameters, including percentage of non-affected glomeruli, interstitial fibrosis, intensity of C3 staining of immunofluorescence, and amount of electron dense deposits by electron microscopy.

Daratumumab in Treatment of PGNMID and C3 GN

Membranoproliferative Glomerulonephritis

This study is being done to see if daratumumab is safe and effective in the treatment of proliferative glomerulonephritis with monoclonal immune deposits (PGNMID) and C3 glomerulopathy associated with monoclonal gammopathy (C3GN). This is an inflammatory disease in the kidney due to the production of abnormal proteins. There are no known standard effective treatments for patients with PGNMID and C3GN secondary to monoclonal gammopathy. These diseases are caused by abnormal production of proteins (monoclonals) by abnormal clones. Daratumamb has been shown to be effective in treating patients with multiple myeloma a disease which also caused by over production of monoclonal proteins from abnormal clones. Everyone in this study will receive daratumumab.

Non-contrast Enhanced MRI in Patients With C3 Glomerulopathy (C3G) or Immune-complex Membranoproliferative...

C3 GlomerulonephritisC3 Glomerulopathy3 more

Functional and quantitative renal magnetic resonance imaging (MRI) has seen a number of recent advances, and techniques are now available that can generate quantitative imaging biomarkers with the potential to improve the management of kidney disease. However, there are knowledge gaps that must be addressed before renal MRI methods could be more widely adopted in clinical research and ultimately be transferred to clinical practice, including the biological basis of different MRI biomarkers, and how the application of these biomarkers will improve patient care. Among renal MRI techniques, renal diffusion weighted MRI (DWI) has been increasingly used in the last decade, showing high potential as a surrogate and monitoring biomarker for interstitial fibrosis in chronic kidney disease (CKD), as well as a surrogate biomarker for the inflammation in acute kidney diseases that may impact patient selection for renal biopsy in acute graft rejection. Within the ready-to-start ACH471-205 clinical trial, an Open-Label Phase 2 Proof-of-Concept Study in Patients with C3 Glomerulopathy (C3G) or Immune-Complex Membranoproliferative Glomerulonephritis (IC-MPGN) treated with ACH-0144471, aimed at evaluating the efficacy of 12 months of oral ACH-0144471 in patients with C3G or IC-MPGN, patients will undergo baseline and 12-month follow-up renal biopsies, and renal function will be assessed over time by estimated or measured (when available) glomerular filtration rate (GFR). Adding multi-parametric NCE-MRI to the examinations under the ACH471-205 study protocol will give the opportunity to elucidate, in a well-defined cohort of patients, the potential of NCE-MRI as biomarker of renal microstructure and functional change.

TP10 Use in Patients With C3 Glomerulopathy (C3G)

Dense Deposit Disease

The purpose of this study is to evaluate the safety of repeated TP10 dosing in pediatric and adult patients with C3G and to evaluate the activity of TP10 in pediatric and adult patients with C3G, as measured by the proportion of patients with normalization of serum C3, serum C3 breakdown products, or alternative pathway (AP) complement activity.
