This press release contains certain forward-looking statements relating to, among other things, our plans to develop electroporation-based drug and gene delivery technologies and DNA vaccines. Actual events or results may differ from the expectations set forth herein as a result of a number of factors, including uncertainties inherent in clinical trials and product development programs, including but not limited to the fact that pre-clinical and clinical results referenced in this release 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 c linical 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 our electroporation technology and DNA vaccines may fail to show the desired safety and efficacy traits in clinical trials; 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 us or our collaborators, including alternatives that may be more efficacious or cost-effective than any therapy or treatment that we and our collaborators hope to develop; whether our proprietary rights are enforceable or defensible or infringe or allegedly infringe on rights of others or can withstand claims of invalidity; the impact of government healthcare proposals and other factors set forth in our Annual Report on Form 10-K for the year ended December 31, 2008, our Form 10-Q for the quarterly period ended June 30, 2009, and other regulatory filings from time to time. There can be no assurance that any product in Inovio s pipeline will be successfully developed or manufactured, that final results of clinical studies will be supportive of regulatory approvals required to market licensed products, or that any of the forward-looking information provided herein will be proven accurate.
