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.

Interventions

Type	Name	Description
DRUG	Huaier granule	Huaier granule, oral administration, 10g each time, 3 times a day, continuous medication for 24 weeks. After 24 weeks of treatment, the dosage should be adjusted according to efficacy.
DRUG	Renin-angiotensin-aldosterone system inhibitors (RASI)	Run-in period: All the patients should be treated with RASI for at least 4 weeks, and stop using any medicine containing Huaier or similar ingredients for at least 2 weeks before enrollment. If the patient is receiving RASI, the RASI can be continued until the end of the study. RASI can be adjusted once a week until the maximum tolerable dose based on albuminuria and blood pressure. If the patient is not receiving RASI therapy, then RASI is recommended. Treatment period: RASI therapy is continued throughout the trial. Check blood pressure twice daily: morning and evening.
DRUG	Ciclosporin soft capsules	The initial dose of Ciclosporin soft capsules is an oral dose of 3.5mg/kg/d, divided into two equal doses, given every 12 hours. Assess the plasma concentration of CsA (valley value) every 2 weeks in the first 8 weeks. If the plasma concentration of CsA reaches 100-150ug/L, continue to maintain the dose. If the plasma concentration of CsA is below the target concentration, increase the dose of CsA. If the plasma concentration of CsA is higher than the upper limit of the target concentration, appropriate dose reduction. A single dose adjustment is 25mg/d. After increasing/decreasing the dose, CsA concentration is remeasured at intervals of 2 weeks ±3 days until the target concentration is reached. CsA at target concentration followed by 24 weeks of treatment, then the dosage shall be adjusted according to efficacy.
