Humanized Influenza Monoclonal Antibodies (SJ-07-0004) |
| Description |
Highly pathogenic avian H5N1 influenza virus is a major public health concern. Given the lack of effective vaccine and recent evidence of antiviral drug resistance in some isolates, alternative strategies for containment of a possible future pandemic are needed. Humanized monoclonal antibodies (mAbs) that neutralize H5N1 virus could be used as prophylaxis and treatment to aid in the containment of such a pandemic.
Investigators from St. Jude Children's Research Hospital and DSO National Laboratories, Singapore developed two neutralizing humanized monoclonal antibodies. One against H5 hemagglutinin from A/Vietnam/1204/05 and the other against A/HongKong/213/03. Both antibodies retained specificity and exhibited prophylactic efficacy in mice.
Studies with these antibodies show passive antibody therapy can be an effective tool for both prophylaxis against- and treatment of- highly pathogenic H5N1 influenza virus, providing the immediate immunity needed which combined with social distancing could limit the transmission of H5N1 virus to others and contain a future influenza pandemic. |
