MGAWN1 is a humanized monoclonal antibody that specifically recognizes the envelope (E) protein of WNV. MGAWN1 exhibits potent neutralizing and fusion-inhibitory activity against WNV in laboratory studies conducted in vitro and in vivo. MGAWN1 has a specific activity that is orders of magnitude higher than that of an intravenous immune globulin (IVIG) product when tested in laboratory studies.

Approximately 20% of humans infected with WNV experience West Nile Feverwith clinical symptoms that include fever, headache, body aches, skin rash and swollen lymph glands. In approximately 1% of human infections, WNV enters the brain and causes severe, life-threatening neuroinvasive disease in the form of encephalitis, meningitis or acute flaccid paralysis. West Nile Neuroinvasive Disease (WNND) is associated with significant morbidity, and long-term neurological effects are common among survivors.
Since 1999, there have been more than 28,000 cases of confirmed symptomatic WNV infection in the U.S., which include more than 11,000 WNND cases and more than 1,100 deaths. In 2008, 1,356 cases of WNV infection were reported to the Centers for Disease Control and Prevention (CDC) for the year with 44 of these cases resulting in death. WNV is now the most common cause of epidemic viral encephalitis in the U.S., and it wil
