ine. "We are pleased that this distinguished group from Johns Hopkins is supporting our efforts, and we look forward to working with all of our investigators in the coming year to generate clinical data enabling us to assess the potential of bavituximab as a possible new therapy for patients co-infected with HCV and HIV."

This open-label, dose escalation study is expected to enroll up to 24 patients chronically infected with HCV and HIV. Patient cohorts will receive ascending dose levels of bavituximab weekly for up to eight weeks. HCV and HIV viral titers and other biomarkers will be evaluated, although they are not formal study endpoints.

In the United States alone, an estimated 300,000 individuals are co-infected with HCV and HIV, representing up to 30% of all HIV-infected patients. Co-infected patients have been shown to have a lower response to current HCV treatment regimens, and the adverse effects of these regimens can be especially problematic for some HIV patients.

About Bavituximab

Bavituximab is a monoclonal antibody in a new class of anti-phosphotidylserine (PS) immunotherapeutics that targets and binds to cellular components that are normally not present on the outside of cells, but which become exposed on certain virally infected cells and on the surface of enveloped viruses, including both HCV and HIV. Bavituximab helps stimulate the body's immune defenses to destroy both the virus particles and the infected cells. Since bavituximab's PS target comes from the host and not the virus, bavituximab may be less susceptible to the development of anti-viral resistance. Peregrine has completed two bavituximab Phase I monotherapy clinical trials in patients with chronic HCV infection. In these trials, the drug appeared safe and well tolerated with encouraging signs of anti-viral activity. Bavituximab is also in Phase II trials for the treatment of solid cancers.
