Idiopathic Membranous Nephropathy Clinical Trial
Official title:
A Pilot Study to Evaluate the Antiproteinuric Effect of Renin Inhibition With Aliskiren in Patients With Idiopathic Membranous Nephropathy
The goal of this proposal is to conduct a pilot study to access the antiproteinuric effect of aliskiren in patients with idiopathic membranous nephropathy. Patients will be treated for 3 months with aliskiren aiming to achieve the maximum tolerated dose and blood pressure (>100 but <125 mmHg systolic BP >75% of the readings).

Inclusion Criteria - Idiopathic MN proven by diagnostic kidney biopsy. - Age =18 years but = 80 years. - Proteinuria as measured by urinary protein/urinary creatinine > 4.0 on a spot sample aliquot from a 24-hour urine collection. - Estimated GFR = 30 ml/min/1.73m^2 using the 4 variable Modification of Diet in Renal Disease (MDRD) equation. Exclusion Criteria - Age <18 years. - Estimated Glomerular Filtration Rate (GFR) < 30 ml/min/1.73m^2, or serum creatinine >3.0 mg/dl. - Patient must be off prednisone, calcineurin inhibitor or mycophenolate mofetil for > 1 month and alkylating agents for > 6 months. - Patients with presence of active infection or a secondary cause of MN (e.g. hepatitis B, HIV, systemic lupus erythematosus (SLE), medications, malignancies). - Type 1 or 2 diabetes mellitus. Patients who have recent history of steroid induced diabetes but no evidence of diabetic nephropathy on renal biopsy performed within 6 months of entry into the study are eligible for enrollment. - Pregnancy or nursing for safety reasons. - Acute renal vein thrombosis documented prior to entry by renal US or CT scan. - Previous therapy with Aliskiren |
