Trial Parameters
Brief Summary
The investigators designed a randomized, controlled, multicenter clinical study to compare the efficacy and safety of rituximab combined with hormones versus rituximab monotherapy in the treatment of primary membranous nephropathy. At the same time, the investigators conducted a real-world study on patients who did not meet the inclusion and exclusion criteria or were unwilling to enter the RCT cohort, to further observe the trial results in a broader population.
