Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older diagnosed with Primary Membranous Nephropathy and exhibiting specific urinary protein levels.

Probably not a fit

Patients with secondary causes of Membranous Nephropathy or those resistant to cyclosporine may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical study evaluates the safety and efficacy of MIL62 in patients with Primary Membranous Nephropathy (pMN) through two phases. In Phase Ib, 30 subjects are randomly assigned to receive either MIL62 at doses of 600mg or 1000mg, or cyclosporine, with safety assessed over four weeks. If deemed tolerable, Phase II will further assess the efficacy of these treatments over a total of 104 weeks, focusing on the overall response rate at 76 weeks as the primary endpoint.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients suffering from Primary Membranous Nephropathy.

How similar studies have gone: While this approach is novel, similar studies evaluating new treatments for pMN have shown promise in the past.
