Abstract

The post-exposure therapeutic efficacy of injectable peramivir against highly pathogenic avian influenza type A H5N1 was evaluated in mice and in ferrets. Seventy to eighty percent of the H5N1-infected peramivir-treated mice, and 70% in the oseltamivir treated mice survived the 15-day study period, as compared to 36% in control (vehicle) group. Ferrets were infected intranasally with H5N1 followed by treatment with multiple doses of peramivir. In two of three trials, a statistically significant increase in survival over a 16-18 day period resulted from peramivir treatment, with improved survival of 40-64% in comparison to mock-treated or untreated animals. Injected peramivir mitigates virus-induced disease, reduces infectious virus titers in the lungs and brains and promotes survival in ferrets infected intranasally with this highly neurovirulent isolate. A single intramuscular peramivir injection protected mice against severe disease outcomes following infection with highly pathogenic avian influenza and multi-dose treatment was efficacious in ferrets.
