Summary
The trial is a random, open, control and monocentric trial. Mainly to assess the urine protein remission rate of tacrolimus (TAC) monotherapy for idiopathic membranous nephropathy (IMN). Assuming that the urine protein remission rate of 48-week TAC for monotherapy of IMN is not lower than that in treatment group of TAC combined with glucocorticoid, attempt on de-hormonal therapy in the future IMN therapy can be attempted on the basis of the trial results.Phase:

Criteria
Inclusion Criteria:1. Age: 18 - 80 years;
2. Those whose clinical manifestation and renal biopsy pathologic diagnosis are IMN
(Stages I-IV) with secondary membranous nephropathy excluded;
3. Those who meet any of the following high-risk IMN standards:
- Urinary protein>8g/24h
- Serum albumin<25g/l
- Serum PLA2R levels are 5 times higher than normal
- eGFR decline rate after confirmed IMN within 6-12 months is ≥30%
- Patients with serious complications: pulmonary embolism, lower extremity static
Vein thrombosis/embolism, acute renal injury, etc.
4. Those without reaching the above high-risk IMN standard, but their course of disease
is >6 months without spontaneous remission,and still present nephrotic syndrome;
5. Patients who have signed the informed consent forms.
Exclusion Criteria:
1. Those whose kidney pathological manifestation of interstitial fibrosis is >30%;
2. Those who are positive in active Hepatitis B (including HBsAg, HBeAg and HBcAb or
HBsAg, HBeAb and HBC) or serological indexes (HBsAg or/and HBeAg or/and HBcAb) or
infected with Hepatitis C, tuberculosis, cytomegalovirus, severe fungal or HIV
infection;
3. Those who suffer from untreated active digestive tract ulcer within 3 months before
random grouping;
4. Those who suffer from uncured malignant tumor for less than 5 years
5. Those who received glucocorticoid (prednisone or prednisolone), mycophenolatemofetil,
tacrolimus, cyclosporine A and other drugs for treatment within 3 months before screen
with a course of treatment exceeding 4 weeks or those who received cyclophosphamide
(accumulated dose>1.0g);
6. Those whose ALT, AST or total bilirubin content goes beyond 1.5 times above normal
upper limit;
7. Those who suffer from combined critical complications such as serious infection or
other severe organ disease or dysfunction;
8. Pregnant or lactating women;
9. Those who are known to be allergic to drugs under trial or relevant products;
10. Those who participated in other clinical trials within 3 months before inclusion;
11. The patients who cannot comply with the research proposal as determined by the
supervising physician.
Exit criteria
1. Those with incomplete or partial relieved proteinuria for 6 months after treatment;
2. Patients or their legal guardians voluntarily requests to withdraw;
3. Those against the inclusion criteria and exclusion criteria;
4. Those who need to take medications prohibited by the trail;
5. Those with poor compliance or stopping the drug for over 2 weeks;
6. Those with uncontrollable infection;
7. Those whit elevated blood glucose during the treatment, which is still difficult to
control after routine treatment by endocrinologists;
8. In the TAC group, the eGFR decreased by >30%, the TAC dose was halved. And the drug
concentration and renal function were reviewed after 2 weeks. If the eGFR decreased by
<30%, it will continue to be used; if the eGFR still decreased by >30%, the TAC dose
continues to halve, or give a minimum dose of 0.5mg / d. And the drug concentration
and renal function were reviewed after 2 weeks. If the eGFR decreased by <30%, TAC
will continue to be used, otherwise stop the drug;
9. Those whose ALT, AST or bilirubin rises to more than 2 times the upper limit of normal
value after treatment, and continues to increase for 2 weeks; those whose ALT, AST or
bilirubin rises to more than 2 times the upper limit of normal value after 2 weeks of
treatment with liver protection, the drug will be discontinued. If it cannot be
recovered after 2 weeks, the patient will withdraw;
10. Those with other unexplained severe comorbidities;
11. Those with pregnancy during treatment;
12. For security reasons, the research sponsor proposed to stop the study;
