Inovio Biomedical Corporation Develops Cordless Electroporation Device for Delivering DNA Vaccines

Published: Mar 03, 2010

SAN DIEGO--(BUSINESS WIRE)--Inovio Biomedical Corporation (NYSE Amex: INO), a leader in DNA vaccine design, development and delivery, has unveiled its new CELLECTRA®-SP series of hand-held, cordless electroporation devices at the DNA Vaccines 2010 conference being held in New Orleans, LA.

Existing generations of electroporation systems consist of an electrical pulse generator box the size of a large laptop attached by a cord to a separate needle-electrode applicator. The new CELLECTRA®-SP devices bring together groundbreaking design and engineering advancements to combine all components into a self-contained, easy-to-use portable device the size of a cordless hand tool.

Inovio's electroporation-based DNA vaccine delivery systems can increase levels of gene expression (i.e. production of the immune-system-stimulating protein the vaccine was coded to produce) of “naked” DNA vaccines by 100-fold or more compared to delivery of naked DNA vaccines via conventional injection alone. Delivery of Inovio’s SynCon™ DNA vaccines into muscle or skin tissue with Inovio’s electroporation systems have generated robust immune responses in disease models including influenza (H5N1 and H1N1), smallpox, and HIV. The strong immune responses have resulted in protection of immunized animals, most notably ferrets and primates, from death and illness following a challenge with the respective pathogens.

More significantly, Inovio has translated these animal study findings into positive clinical results. Inovio’s clinical studies with electroporation delivery of DNA vaccines in cancer patients have been among the first to demonstrate generation of potent antigen-specific immune responses in humans. Inovio recently announced that its therapeutic cervical cancer vaccine VGX-3100 showed significant dose-related T-cell and antibody responses in an on-going Phase I study.

The new CELLECTRA®-SP products combine the functionality of its current generation of skin and intramuscular electroporation devices in clinical testing with enhanced form, design, and portability. All components from the pulse generator and applicator are integrated into a cordless, rechargeable device. The rechargeable battery can enable vaccination of several hundred subjects, making the device highly amenable to mass vaccination. The devices are designed to accommodate different electrode arrays to meet the requirements of the particular vaccine and tissue for delivery (skin or muscle).

Dr. J. Joseph Kim, president and CEO, stated, “The new CELLECTRA®-SP device is a testament to the skills of Inovio’s engineering and research teams. As we look beyond the proof-of-concept stage for our DNA vaccine and delivery programs, our goal is to continue our industry leadership in developing and commercializing new vaccines which could improve the lives of millions of people around the world.”

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 the first component of its universal influenza vaccine. Inovio is developing its universal 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

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.
