Inovio Biomedical Corporation (NYSE Amex: INO), a leader in DNA vaccine design, development and delivery, announced today that it has expanded its existing license agreement with the University of Pennsylvania, adding exclusive worldwide licenses for technology and intellectual property for novel DNA vaccines against pandemic influenza, Chikungunya, and foot-and-mouth disease. The amendment also encompasses new chemokine and cytokine molecular adjuvant technologies. The technology was developed in the University of Pennsylvania laboratory of Professor David B. Weiner, a pioneer in the field of DNA vaccines, and chairman of Inovio’s scientific advisory board.

Dr. J. Joseph Kim, president and CEO, stated, “Our DNA vaccine technology offers the potential to prevent and/or treat a broad array of cancers and infectious diseases, and has achieved compelling preclinical and initial clinical results. This new intellectual property from an eminent DNA vaccine research laboratory broadens our opportunities to pursue important new infectious diseases.”

Under the terms of the original license agreement completed in 2007, the Company obtained exclusive worldwide rights to develop multiple DNA plasmids and constructs with the potential to treat and/or prevent HIV, HCV, HPV and influenza and included molecular adjuvants. These prior and most recent agreements and amendments provide for royalty payments, based on future sales, to the University of Pennsylvania.

About Inovio Biomedical Corporation

Inovio Biomedical is focused on the design, development, and delivery of a new generation of vaccines, called DNA vaccines, to prevent and treat cancers and infectious diseases. The company’s SynCon™ technology enables the design of “universal” vaccines capable of protecting against multiple – including newly emergent, unknown – strains of pathogens such as influenza. Inovio’s proprietary electroporation-based DNA vaccine delivery technology has been shown by initial human data to safely and significantly increase gene expression and immune responses. Inovio’s clinical programs include HPV/cervical cancer (therapeutic) and HIV vaccines. An IND has been filed for an avian influenza vaccine. Inovio is developing its universal and avian influenza vaccines in collaboration with scientists from the University of Pennsylvania, the National Microbiology Laboratory of the Public Health Agency of Canada, and the NIH’s Vaccine Research Center. Other partners and collaborators include Merck, Tripep, University of Southampton, National Cancer Institute, and HIV Vaccines Trial Network. More information is available at www.inovio.com.

This press release contains, in addition to historical information, forward-looking statements. Such statements are based on management’s current estimates and expectations and are subject to a number of uncertainties and risks that could cause actual results to differ materially from those described in the forward-looking statements. Inovio is providing this information as of the date of this press release, and expressly disclaims any duty to update information contained in this press release.

Forward-looking statements in this press release include, without limitation, express and implied statements relating to Inovio’s business, plans to develop electroporation-based drug and gene delivery technologies and DNA vaccines and pre-clinical and clinical studies. Actual events or results may differ from the expectations set forth herein as a result of a number of risks, uncertainties and other factors, including but not limited to: Inovio has a history of losses; all of Inovio’s potential human products are in research and development phases; no revenues have been generated from the sale of any such products, nor are any such revenues expected for at least the next several years; Inovio’s product candidates will require significant additional research and development efforts, including extensive preclinical and clinical testing; uncertainties inherent in clinical trials and product development programs, including but not limited to the fact that pre-clinical and clinical results may not be indicative of results achievable in other trials or for other indications, that results from one study may not necessarily be reflected or supported by the results of other similar studies, that results from an animal study may not be indicative of results achievable in human studies, that clinical testing is expensive and can take many years to complete, that the outcome of any clinical trial is uncertain and failure can occur at any time during the clinical trial process, and that Inovio’s electroporation technology and DNA vaccines may fail to show the desired safety and efficacy traits in clinical trials; all product candidates that Inovio advances to clinical testing will require regulatory approval prior to commercial use, and will require significant costs for commercialization; the availability of funding; the ability to manufacture vaccine candidates; the availability or potential availability of alternative therapies or treatments for the conditions targeted by Inovio or its collaborators, including alternatives that may be more efficacious or cost-effective than any therapy or treatment that Inovio and its collaborators hope to develop; whether Inovio’s proprietary rights are enforceable or defensible or infringe or allegedly infringe on rights of others or can withstand claims of invalidity; and the impact of government healthcare proposals. Readers are also referred to Inovio’s Annual Report on Form 10-K for the year ended December 31, 2008 and its Quarterly Report on Form 10-Q for the quarter ended September 30, 2009 filed with the Securities and Exchange Commission which identify important risk factors that could cause actual results to differ from those contained in the forward-looking statements.
