MMF-STOP-IMN: Mycophenolate Mofetil Plus Steroid in the Treatment Of Patients With Progressive Idiopathic Membranous Nephropathy
Study Details
Study Description
Brief Summary
Idiopathic membranous nephropathy (IMN) remains a common cause of the nephrotic syndrome in adults. There are few randomized clinical trials regarding the therapeutic effect of mycophenolate mofetil in patients with Idiopathic membranous nephropathy. This study aims to evaluate whether treatment with mycophenolate mofetil is non-inferior to cyclosporins in inducing long-term remission (complete or partial) of proteinuria in patients with idiopathic membranous nephropathy.

Detailed Description
Idiopathic membranous nephropathy is the most common cause of nephrotic syndrome in adults. In recent year, IMN remains one of the most common glomerular diseases. Long-term remission and stable renal function can prevent idiopathic membranous nephropathy from progressing to end-stage renal disease. Cyclosporine and cyclophosphamide are recommended to be first-line treatment regimen. Corticosteroid is the basic combined drug in the treatment of idiopathic membranous nephropathy. Mycophenolate mofetil is a recently developed immunosuppressive agent with fewer renal toxicity than cyclosporin.Besides, high dose prednisone may be effective for patients in Asia according to literatures from Asia. In our study, patients with idiopathic membranous nephropathy would be treated with mycophenolate mofetil and high dose prednisone,whose outcome will be compared with cyclosporin and low dose prednisone. We aims to evaluate whether treatment with mycophenolate mofetil is non-inferior to cyclosporins in inducing long-term remission of proteinuria in patients with idiopathic membranous nephropathy.

Outcome Measures
Primary Outcome Measures
- Complete Remission [after treatment for 1 year.]
Urinary protein excretion<0.3 g/d (uPCR<300 mg/g or <30 mg/mmol), confirmed by two values at least 1 week apart, accompanied by a normal serum albumin concentration, and a normal serum creatinine.
- Partial Remission [after treatment for 1 year.]
Urinary protein excretion <3.5 g/d (uPCR <3500 mg/g or <350 mg/mmol) and a 50% or greater reduction from peak values;confirmed by two values at least 1 week apart, accompanied by an improvement or normalization of the serum albumin concentration and stable serum creatinine.
Secondary Outcome Measures
- estimated Glomerular Filtration Rate [after treatment for 1 year]
time to a 50% reduction in baseline estimated Glomerular Filtration Rate (according to CKD-EPI)
- serum creatinine [after treatment for 1 year]
time to doubling of baseline creatinine
