Summary

This study was divided into two stages. In the first stage (Phase Ib), 30 subjects were randomly divided into MIL62 600mg, MIL62 1000mg and cyclosporine groups at a ratio of 1:1:1, with 10 subjects in each group. Tolerance to MIL62 was evaluated within 4 weeks after the first administration. If the overall safety is determined by the investigator and sponsor to be tolerable to MIL62, phase II enrollment will be initiated.

The second stage was also randomly divided into MIL62 600mg, MIL62 1000mg and cyclosporine groups according to the ratio of 1:1:1, 30 subjects in each group, to evaluate the efficacy of MIL62 and cyclosporine in the treatment of primary membranous nephropathy. Eligible subjects in both phases received treatment and follow-up for a total of 104 weeks. The 76-week overall response rate was the primary endpoint.
