BG9588 (Anti-CD40L Antibody) to Treat Lupus Nephritis Clinical Trials Information presented on Clinical Trials Search isn't designed to be a substitute for certified healthcare advice, travels to or professional assistance using a genuine medical doctor. We are not physicians. Always confer with your dr. about BG9588 (Anti-CD40L Antibody) to Treat Lupus Nephritis conditions. Clinical Trials Search.org is a site devoted to listing clinical research studies in human subjects. BG9588 (Anti-CD40L Antibody) to Treat Lupus Nephritis Clinical research trials and BG9588 (Anti-CD40L Antibody) to Treat Lupus Nephritis medical trials happen in hundreds of places across the United States. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually measure the effectualness of new drugs. The intention of the studies / undertakings is to solve certain human healthcare questions. Clinical trials are a popular manner for mDs, government agencies, and private sector companies to locate treatments for all forms of circumstances, such as BG9588 (Anti-CD40L Antibody) to Treat Lupus Nephritis. BG9588 (Anti-CD40L Antibody) to Treat Lupus Nephritis Clinical Trials and other clinical trials allow for volunteers to undergo medical treatment choices before they are available to the general public. Some times the human subjects get treatment for free of charge, and sometimes they are paid for their time. Occasionally there is a cost for a BG9588 (Anti-CD40L Antibody) to Treat Lupus Nephritis clinical trial. Participants frequently get the best healthcare available for their BG9588 (Anti-CD40L Antibody) to Treat Lupus Nephritis condition. Risks are a reality, nonetheless, and can include extra or frequent physician trips, medical risks (possibly life-jeopardising), and/or the treatment being ineffective. Trials are federally governed with exacting guidelines to protect clinical trials subjects.

BG9588 (Anti-CD40L Antibody) to Treat Lupus Nephritis
For Condition: Glomerulonephritis, Membranoproliferative,Lupus Nephritis
Status: Completed
Sponsor(s): National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) ,
Synopsis: 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.
Details: Studies in animals and humans with lupus nephritis have demonstrated that essential role of CD40 ligand/CD40 interaction in the production of pathogenic autoantibodies. Anti-CD40L antibody treatment of mice with lupus nephritis ameliorates disease and improves survival. BG9588 is a recombinant humanized monoclonal antibody that specifically binds to CD40 ligand (CD40L) expressed on the surface of activated T lymphocytes and thereby blocks the CD40L/CD40 interaction between T and B cells that is required for the initiation for certain antibody responses. Available preclinical data indicates that BG9588 does not cause a global blockage of the immune response to pathogens and that its effects are reversible upon clearance from the systemic circulation. In this Phase I/II open-label, multiple-dose, multicenter study, 30 subjects with active proliferative lupus nephritis will receive 20 mg/kg BG9588 by IV infusion once every 14 days for three doses, and then once every 28 days for four doses for a total of 7 doses. The primary objective is to determine if BG9588 can decrease proteinuria by greater than or equal to 50 percent from baseline without worsening renal function. The secondary objectives are to determine the safety and pharmacokinetics of BG9588, as well as the effects of BG9588 on renal flares; cellular casts; C(3) levels and anti-dsDNA titers; requirement for prednisone; general lupus activity; and quality of life.
