Ebola virus

Ebola glycoprotein GP1; Ebola glycoprotein GP2

Primate studies suggest combining anti-Ebola antibodies plus interferon-a (IFNA; IFN-a) could help treat Ebola virus. In cynomolgus and rhesus macaques, ZMAb-a combination of three murine antibodies that target GP1 and GP2-plus DEF201, an adenoviral vector-delivered IFN-a, protected 75%-100% of animals when given
3 days after infection. In cynomolgus macaques, DEF201 beginning 1 day postinfection plus ZMAb beginning
4 days postinfection protected 50% of animals. Next steps include ongoing safety and toxicology studies for ZMAb and clinical testing of ZMAb and DEF201 by Defyrus Inc.
