Abstract | Background:
MEDI8852 is a novel monoclonal antibody (mAb) that neutralizes both group I and group II influenza A viruses (IAVs) in vitro. We evaluated whether MEDI8852 was effective for prophylaxis and therapy against representative group I (H5N1) and group II (H7N9) pandemic IAVs in mice and ferrets and could be used to block transmission of influenza H1N1pdm09 in ferrets, compared to an irrelevant control mAb R347 and oseltamivir. Methods:
MEDI8852 was administered to mice and ferrets by intraperitoneal injection at varying doses, 24 hours prior to intranasal infection with H5N1 and H7N9 viruses for prophylaxis, and 24, 48, and 72 hours post- infection for treatment. A comparison with oseltamivir alone and combination of MEDI8852 and oseltamivir was included in some studies. Survival, weight loss, and viral titers were assessed over a 14-day study period. For the transmission study, naive respiratory contact ferrets received MEDI8852 or R347 prior to exposure to ferrets infected with an H1N1pdm09 virus. Results: Conclusions:
