Barton Haynes, M.D., director of the Duke Human Vaccine Institute and senior author of the study commented, "These results indicate that targeting a host cell lipid such as PS as an anti-viral strategy is a promising concept of relevance to new therapeutic and possibly prophylactic innovations for HIV."
Peregrine's most advanced PS-targeting antibody bavituximab is currently being studied in a clinical trial for the treatment of patients co-infected with hepatitis C virus (HCV) and HIV. Earlier Phase I studies in HCV patients showed that bavituximab was well tolerated and it exhibited encouraging signs of anti-viral activity. Under a major biodefense initiative, bavituximab and a fully human equivalent antibody are also in preclinical development for the treatment of viral hemorrhagic fevers (VHF). In November, 2009 Peregrine researchers presented positive data on progress in this program, showing that the PS-targeting antibodies increase survival in a model of lethal VHF infection.
"This publication is the latest in a series of presentations and publications that supports the potential of PS as a target in HIV infection and provides new insights into the unique mechanisms of action of our PS-targeting antibodies," said Steven W. King, president and CEO of Peregrine. "While past studies have focused on the broad nature of the PS target, these new data reveal that some of these antibodies may also have highly specific effects."
