A Study to Learn More About the Effects and Safety of Felzartamab Infusions in Adults With Primary Membranous Nephropathy (PMN)
Recruiting
In this study, researchers will learn more about the use of felzartamab in participants with primary membranous nephropathy, also known as PMN.

An autoantibody is a type of antibody that mistakenly targets and attacks the body's own tissues. Glomeruli are the filters of the kidney that remove waste and extra fluid from the body. In PMN, the build-up of autoa... Read More
