Rituximab for Severe Membranous Nephropathy: A 6-Month Trial with Extended Follow-Up.

Randomized trials of rituximab in primary membranous nephropathy (PMN) have not been conducted. We undertook a multicenter, randomized, controlled trial at 31 French hospitals (NCT01508468). Patients with biopsy-proven PMN and nephrotic syndrome after 6 months of nonimmunosuppressive antiproteinuric treatment (NIAT) were randomly assigned to 6-month therapy with NIAT and 375 mg/m intravenous rituximab on days 1 and 8 (n=37) or NIAT alone (n=38).
