In the first study, 100% of mice infected with lethal murine CMV and treated with bavituximab recovered fully, while only 25% of control animals survived. In the second study, guinea pigs were infected with lethal Pichinde virus, which is a model virus for Lassa fever. Fifty percent of the bavituximab-treated group survived, while untreated animals all died. In this study, the anti-viral effect of bavituximab was further augmented by the addition of the standard of care drug ribavirin, with 63% of animals receiving the combination therapy surviving the potentially lethal infection.
"We are extremely pleased to see this research demonstrating the broad anti-viral potential of bavituximab and our anti-PS technology platform published in this highly regarded journal," said Steven W. King, president and CEO of Peregrine. "This new publication is the latest in a series of external validations of our anti-viral program. It follows a recently awarded federal government contract for assessment of anti-PS antibodies to treat viral hemorrhagic fevers, research on the role of PS in viral infections that was published in a leading science journal earlier this year, and a recent presentation on anti-PS antibodies at a global HIV conference."
Mr. King added, "Better prevention and treatment of viral diseases are urgently needed, and we are increasingly optimistic that bavituximab and our other anti-PS antibodies could be valuable contributors to the field."
