May 3, 2024 updated by: Shiren sun, Air Force Military Medical University, China

Efficacy and Safety of Immunosuppressive Therapy for IgA Nephropathy With Stage 3 or 4 Chronic Kidney Disease

The purpose of this clinical trial is to evaluate the long-term efficacy and safety of low-dose oral corticosteroids combined with cyclophosphamide therapy and low-dose corticosteroids monotherapy, on a background of maximal RAS inhibitor therapy, for IgA nephropathy with stage 3 or 4 chronic kidney disease.
