Usage of Veopoz

Veopoz (pozelimab-bbfg) is used to treat CHAPLE disease, also known as CD55-deficient protein-losing enteropathy. CHAPLE disease is a rare and life-threatening hereditary immune disease caused by an overactivation of the complement system. 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.

CHAPLE (complement hyperactivation, angiopathic thrombosis, and protein-losing enteropathy) disease is an immune disorder caused by an overactive complement system, which is part of the immune system. Usually, the complement system helps fight microbes and is kept under control by the CD55 gene. In CHAPLE disease, there are mutations in the CD55 gene which means complement activity is unregulated and attacks normal cells. This causes damage to blood and lymph vessels along the upper digestive tract and leads to the loss of circulating proteins. Veopoz blocks complement factor C5 to regulate the complement system.

Veopoz became the first FDA-approved medicine for CD55-deficient protein-losing enteropathy on August 18, 2023. Approval was based on positive results from the Phase 2/3 open-label trial (NCT04209634), showing improvement in serum albumin concentrations. All 10 patients using Veopoz achieved normalization by Week 12 and maintained serum albumin concentrations within the normal range through at least 72 weeks of treatment. Veopoz is approved for use for the treatment of adult and pediatric patients 1 year of age and older with CHAPLE disease.
