The new patent grants composition of matter claims that cover multiple formulations of phosphatidylethanolamine (PE)-binding agents attached to a wide variety of anti-viral agents. PE belongs to the aminophospholipid family that also includes phosphatidylserine (PS), the target for Peregrine's monoclonal antibody bavituximab that is in a clinical trial for hepatitis C virus (HCV) infection and in preclinical studies for HIV and other viral infections. This new patent follows issuance last year of broad methods patents covering use of PE-binding agents in anti-viral applications.
