Apellis (APLS) Pharmaceuticals announced that the U.S. Food and Drug Administration has approved EMPAVELI as the first treatment for C3 glomerulopathy or primary immune complex membranoproliferative glomerulonephritis in patients 12 years of age and older, to reduce proteinuria. C3G and primary IC-MPGN are rare kidney diseases, affecting 5,000 people in the United States. 'I'm excited to now have a highly effective therapy for a broad range of patients living with C3G and primary IC-MPGN,' said Carla Nester, M.D., MSA, FASN, lead principal investigator for the VALIANT study, professor of internal medicine and pediatrics and director of pediatric nephrology, University of Iowa Stead Family Children's Hospital. 'With standard of care, patients living with these rare and severe diseases frequently progress to kidney failure, necessitating lifelong dialysis and/or a kidney transplant. Given the urgent need, particularly in children, the approval of EMPAVELI marks a pivotal moment in the treatment of rare kidney diseases.' In the Phase 3 VALIANT study, EMPAVELI demonstrated an unprecedented 68% reduction in proteinuria, stabilization of kidney function, and substantial clearance of C3 deposits as measured by C3 staining, compared to placebo. The positive results were consistent across adolescent and adult patients with C3G and primary IC-MPGN, and in C3G patients with post-transplant disease recurrence.
