Personalized Medicine for Membranous Nephropathy
In Brief
A Phase 2 clinical trial evaluating Rituximab for Idiopathic Membranous Nephropathy. Completed, enrolled 68 participants across 19 sites.
Detailed Summary
Randomized, open label, multicentre (20 sites), prospective trial comparing the efficacy of two therapeutic strategies to obtain clinical remission 1 year after diagnosis of Idiopathic Membranous Nephropathy with nephrotic syndrome and anti-PLA2R1 (phospholipase A2 receptor 1) antibodies: * GEMRITUX protocol: 6 months of symptomatic antihypertensive and antiproteinuric therapy, and if the nephrotic syndrome persists at month-6 (urinary protein/creatinine ratio (UPCR) remains \> 3.5 g/g and albuminemia \< 30 g/l), two 375 mg/m2 rituximab infusions at 1-week interval. * Personalized treatment: * restricted anti-CysR activity at inclusion : 6-month symptomatic antihypertensive and antiproteinuric treatment (KDIGO) * restricted anti-CysR activity after 6 months of symptomatic treatment with persisting nephrotic syndrome (UPCR remains \> 3.5 g/g and albuminemia \< 30 g/l): two 375 mg/m2 rituximab infusions at 1-week interval; * Anti-CTLD (C-type lectin domains ) 1/7 activity at inclusion or after 6 months with persisting nephrotic syndrome (UPCR remains \> 3.5 g/g and albuminemia \< 30 g/l): two 1g rituximab infusions at 2-week interval at month 0 and/or month 6.
