Vilobelimab

Vilobelimab, sold under the brand name Gohibic, is a monoclonal antibody that is used for the treatment of COVID-19. It is a human-mouse chimeric IgG4 kappa antibody that targets human C5a in plasma.

The most common adverse reactions include pneumonia, sepsis, delirium, pulmonary embolism, hypertension, pneumothorax, deep vein thrombosis, herpes simplex, enterococcal infection, bronchopulmonary aspergillosis, hepatic enzyme increased, urinary tract infection, hypoxia, thrombocytopenia, pneumomediastinum, respiratory tract infection, supraventricular tachycardia, constipation, and rash.

Vilobelimab is a recombinant chimeric monoclonal IgG4 antibody that specifically binds to the soluble human complement split product C5a after cleavage from C5 to block its interaction with the C5a receptor, both of which are components of the complement system thought to contribute to inflammation and worsening of COVID-19. Vilobelimab was granted an emergency use authorization (EUA) by the US Food and Drug Administration (FDA) in April 2023. Vilobelimab was authorized for medical use in the European Union in January 2025.
