Cell culture and mouse studies suggest the human mAb MPE8 could help treat or prevent RSV and metapneumovirus (MPV) infection. The antibody was isolated from immortalized memory B cells obtained from blood donors with high serum neutralizing antibody titers against both viruses. In vitro and in cell culture, MPE8 neutralized RSV and MPV by binding to the prefusion F protein. In a mouse model of RSV infection, MPE8 was 5- to 10-fold more potent than Synagis palivizumab at decreasing virus levels in the lung. Next steps could include a clinical trial of MPE8 in transplant patients who have an upper respiratory tract infection caused by RSV or MPV.
AstraZeneca plc and Abbott Laboratories market Synagis, a humanized mAb against RSV F protein, as a prophylactic for RSV infection.

AstraZeneca's motavizumab, a humanized anti-RSV F protein mAb, is in Phase III trials as a prophylactic for RSV infection.
