Efficacy of Belimumab and Rituximab Compared to Rituximab Alone for the Treatment of Primary Membranous Nephropathy


People with Primary MN lose more protein in their urine because the filters in their kidneys may be damaged. It is possible that some belimumab may also be lost in the urine because of this. This study will measure belimumab in the blood to decide if people with high urine protein should receive a higher dose of belimumab. Another purpose of this study is to help learn about whether the combination of belimumab and rituximab treatment is effective in making and keeping Primary MN inactive.
