Mycophenolate Mofetil (MMF) in Patients With IgA Nephropathy (IgAN)
IgA Nephropathy
About this trial
This is an interventional treatment trial for IgA Nephropathy focused on measuring IgA nephropathy, mycophenolate mofetil
Eligibility Criteria
Inclusion Criteria:
- Willingness to sign an informed consent
- Age:14~60 years, regardless of gender
- Clinical evaluation and renal biopsy diagnostic for IgAN, excluded secondary IgAN. Renal histological criteria should be defined by Lee's glomerular grading system.
- 1 g/day <= proteinuria < 3.5 g/day, or UPr/Cr ratio ≥ 0.6 (male) or ≥ 0.8 (female) when taking ARB
- eGFR ≥ 40 mL/min/1.73 m2
Exclusion Criteria:
- Inability or unwillingness to sign the informed consent
- Inability or unwillingness to meet the scheme demands raised by the investigators
- Rapidly progressive nephritic syndrome and acute renal failure, including rapidly progressive IgAN ( IgAN with rapid decline in renal function characterized histologically by necrotizing vasculitis and crescent formation≥30%) necessitating the use of other immunosuppressive agents.
- Secondary IgAN such as systemic lupus erythematosus, Henoch-Schonlein purpuric nephritis and hepatitis B -associated nephritis
- est GFR < 40 mL/min/1.73m2
- Malignant hypertension that is difficult to be controlled by oral drugs
- Cirrhosis, chronic active liver disease.
- History of significant gastrointestinal disorders (e.g. severe chronic diarrhea or active peptic ulcer disease.)
- Any Active systemic infection or history of serious infection within one month of entry or known infection with HIV, hepatitis B, or hepatitis C.
- Other major organ system disease (e.g. serious cardiovascular diseases including congestive heart failure , chronic obstructive pulmonary disease, asthma requiring oral steroid treatment or central nervous system diseases)
- Malignant tumors (except fully cured basal cell carcinoma)
- Absolute neutrophil count < 1500/mm3, absolute platelet count <75000/mm3 or hematocrit (Hct) <28% (anemic subjects may be reevaluated after the anemia has been treated.)
- Known allergy, contraindication or intolerance to the MMF, corticosteroids or ACEI/ARB.
- Pregnancy or breast feeding at the time of entry or unwillingness to comply with measures for contraception
- Current exposure to MMF or azathioprine. In case of current treatment with oral steroid or ACEI/ARB, entry is permitted after corticosteroids or ACEI/ARB are stopped for 2 weeks.
- Current or recent (within 30 days) exposure to any other investigational drugs

Pred plus MMF Group
Pred Group: Prednisone treatment Patients will give methylprednisolone intravenously at a dose of 0.5 g/day for 3 days at the start of months 1, 3, and 5; then take oral prednisone (0.5 mg/kg/d) on alternate days. Prednison will be tapered 5 mg per month from the seventh month to the 12th month.
MMF Group: MMF treatment Patients will take MMF 1.0g bid (wt ≥ 50kg) or 0.75g bid (wt < 50kg) for the first 6-month of drug treatment phase, then 0.5 bid for the remaining 6-month.
Pred plus MMF Group: Prednisone plus MMF treatment. Patients will give methylprednisolone intravenously at a dose of 0.5 g/day for 3 days at the start of months 1, 3, and 5; then take oral prednisone (0.5 mg/kg/d) on alternate days. Prednison will be tapered 5 mg per month from the seventh month to the 12th month. Patients will take MMF 1.0g bid (wt ≥ 50kg) or 0.75g bid (wt < 50kg) for the first 6-month of drug treatment phase, then 0.5 bid for the remaining 6-month.
