NCIt related terms : MEDI-8852;
NCIt definition : A human immunoglobulin (Ig) G1 kappa monoclonal antibody (mAb) targeting a unique
epitope in the stalk of the influenza A hemagglutinin (HA) protein, with broad influenza
A virus neutralization activity. MEDI8852 was derived from an antibody isolated from
human memory B-cells from patients previously infected with influenza caused by type
A strains that was further optimized to increase neutralization potential. Upon infusion,
MEDI8852 targets and binds to a region within the stalk of the HA protein that is
highly conserved amongst all influenza A virus subtypes. This neutralizes and prevents
essential steps of the viral lifecycle, thereby blocking infectivity of all influenza
A virus subtypes. HA, a glycoprotein found on the surface of the influenza virus,
plays a key role in viral attachment and cell entry.;
