  • Research summary

    This study is testing if a new medicine called povetacicept can help people with a rare kidney disease called primary Membranous Nephropathy (pMN). In pMN, the body's immune system attacks the kidneys, causing protein to leak into urine (pee). This can make people sick and stop the kidneys from working. Current treatments don't work for everyone, so more effective treatment options are needed.
    The study has two parts:
    1. Phase 2b: people participating in this part of the study will receive povetacicept . Povetacicept is given as an injection under the skin, once every 4 weeks.
    Researchers will choose which dose of povetacicept will be used in the next part of the study.
    Phase 3: in this part of the study, povetacicept will be compared to a standard treatment for pMN.
    The goal is to see if povetacicept is safe and works better than current treatments for pMN. Participants will be monitored for side effects and improvements in their condition.
    In total, around 176 people will participate in this study across multiple countries. Vertex Pharmaceuticals is running the study.
