- Brief Summary
This is a prospective, multicenter, randomized, open-label, parallel controlled study. The purpose of this study is to evaluate the efficacy and safety of Huaier granule on the treatment of idiopathic membranous nephropathy comparing with Ciclosporin soft capsules.
- Detailed Description
Idiopathic membranous nephropathy (IMN) is a common immune-mediated glomerular disease, accounting for 20% to 36.8% of adult nephrotic syndrome. A third of the patients will experience complete remission spontaneously, and 30%-40% of patients will develop chronic renal failure. The treatment of IMN includes supportive therapy and immunosuppressive therapy. Ciclosporin (CsA) is a kind of calcineurin inhibitor (CNI) recommended by the Kidney disease improving global outcomes (KDIGO) clinical practice guideline for IMN treatment. CsA is effective in inducing remission among patients with steroid-resistant nephrotic IMN, and studies showed the clinical remission rate was 60%-75%. However, it has a high rate of relapse during follow-up in 6-12 months.
Huaier granule is an extract from a medicinal fungus. Previous studies showed that Huaier granule reduced the excretion of proteinuria, inhibited inflammation and cellular transdifferentiation, and protect renal function.
In this study, about 30 research centers will participate. We plan to enroll 480 participants (240 cases in the experimental group and 240 cases in the control group). The planned length of patient recruitment enrolment will be 2 years and the total length of visits be 1 year.

- Primary Outcome Measures
Name Time Method Overall clinical remission rate at 24, 48, 96 weeks Start of randomization until 96 weeks Overall clinical remission rate is defined as rate of complete remission and partial remission. Complete remission is defined as a 24-h urinary protein level \< 0.3g/d with normal serum albumin level and stable renal function. Partial remission is defined as 24-h urinary protein level \< 3.5g/d with peak value reduction ≥ 50%, accompanied by improved or normal serum albumin, stable renal function.
