Abstract: Treatment options for refractory membranous nephropathy are limited. Herein we describe the case of a 46-year-old white male with membranous nephropathy who progressed during 3 years of treatment with antihypertensive agents (specifically angiotensin-converting enzyme inhibitors and angiotensin receptor blockers), diuretics, simvastatin, prednisone, cyclosporine A, and mycophenolate mofetil. Prior to initiation of treatment with H.P. Acthar® Gel, his proteinuria level was 9,520 mg/dL (952.0 g/L) but it decreased to 2,948 mg/dL (294.8 g/L) after 10 months of Acthar therapy. After 13 months, treatment with Acthar was halted as his 24-hour urinary protein was 1,628 mg/dL (162.8 g/L); by 15 months, it was 407 mg/dL (40.7 g/L). The patient has remained free of signs and symptoms of membranous nephropathy for 1.5 years. These results support the use of Acthar as an effective and safe therapy for patients with refractory membranous nephropathy.
