BLUE BELL, Pa.--(BUSINESS WIRE)--Inovio Pharmaceuticals, Inc. (NYSE Amex: INO), a leader in the development of therapeutic and preventive vaccines against cancers and infectious diseases, announced today that the peer-reviewed journal Molecular Therapy has published a paper entitled “Comparative Analysis of Immune Responses Induced by Vaccination With SIV Antigens by Recombinant Ad5 Vector or Plasmid DNA in Rhesus Macaques.” The paper, co-authored by researchers from Merck, University of Pennsylvania School of Medicine, and Inovio Pharmaceuticals, notes that significant advances in the design, formulation, and delivery of DNA plasmid-based vaccines have dramatically increased their ability to induce antigen-specific immune responses. In this head-to-head comparison with an adenovirus serotype 5 (Ad5) vaccine considered to be the most immunogenic among viral vectors, Inovio’s optimized SynCon™ DNA vaccine delivered using its proprietary electroporation technology demonstrated numerous advantages in both magnitude and breadth of immune responses produced in non-human primates.
