Regeneron Wins FDA Approval for Rare Immune
Regeneron Pharmaceuticals, Inc. has announced that the U.S. Food and Drug Administration (FDA) has approved Veopoz™ (pozelimab-bbfg) for the treatment of adult and pediatric patients 1 year of age and older with CHAPLE disease, also known as CD55-deficient protein-losing enteropathy.
CHAPLE is an ultra-rare and life-threatening hereditary immune disease driven by an overactivation of the complement system. In healthy individuals, the complement system is a mechanism for destroying microbes. However, those living with CHAPLE are unable to regulate complement activity due to mutations in their CD55 gene. Without proper CD55 regulation, the complement system may attack normal cells, causing damage to blood and lymph vessels along the upper digestive tract and leading to the loss of circulating proteins. There are fewer than 10 patients with CHAPLE disease identified in the U.S. Veopoz is a fully human, monoclonal antibody G4 (IgG4) that blocks the activity of complement factor C5 to regulate the complement pathway and relieve the symptoms of CHAPLE disease.
