NanoViricides, Inc. (OTC BB: NNVC.OB) (the "Company"), reports that it has signed a research and development agreement with Dr. Eva Harris's laboratory at the University of California, Berkeley (UC Berkeley).
Under this agreement, Dr. Harris and coworkers will evaluate the effectiveness of nanoviricides(R) drug candidates against various dengue viruses. Cell culture models as well as in vivo animal studies will be employed for testing the drug candidates.
The Company believes that a nanoviricide drug under development can be expected to be a broad-spectrum anti-dengue antiviral treatment capable of attacking all four dengue virus serotypes and their variant strains. Currently there are no approved vaccines for the prevention of dengue, nor drugs for treatment of dengue virus infection. The worldwide market size for an effective anti-dengue treatment may be as large as that for Hepatitis C virus treatment, or in the billions of dollars, based on current population exposure data.
Dr. Eva Harris is a Professor of Infectious Diseases at UC Berkeley. She is a leading researcher in the field of dengue. Her group has developed a unique animal model for dengue virus infection and disease that effectively emulates the pathology seen in humans. In particular, the critical problem of dengue virus infection, called "Antibody-Dependent Enhancement" (ADE), is reproduced in this animal model. When a person who was previously infected with one serotype of dengue virus is later infected by a different serotype, the antibodies produced by the immune system can lead to increased severity of the second dengue infection, instead of controlling it. ADE thus can lead to severe dengue disease or dengue hemorrhagic fever (DHF).
Dengue and dengue hemorrhagic fever/dengue shock syndrome are emerging as serious global health problems. Dengue is endemic in large parts of the world. It now threatens over 3 billion people world-wide or 40% of world population, and is considered a re-emerging threat in the United States. Dengue is officially considered a "neglected tropical disease" by the World Health Organization. About 50-100 million people are infected by dengue virus every year. In fact, just recently, the government of Cali, Columbia declared a dengue emergency because of the number of dengue infections and deaths. Globalization and warming climates along with changes in the ecology of the virus-carrying mosquito are accelerating the spread of the virus. Without proper treatment, DHF fatality rates can exceed 20%. (Source: WHO Dengue and dengue hemorrhagic fever Fact Sheet No. 117, March 2009; www.who.int/mediacentre/factsheets/fs117/en/).
Using computer modeling, the Company has developed a library of small chemical ligands that bind to dengue virus envelope proteins. Using these ligands, a number of candidate nanoviricides that are capable of attacking the dengue virus have been developed. The Company believes that these nanoviricide drug candidates mimic the natural, common attachment function by which the four different dengue virus serotypes bind to the body's host cells.
"We are very excited about this association with the Harris Lab," said Dr. Eugene Seymour, MD, MPH, CEO of the Company, adding, "We will now be able to rapidly advance our anti-dengue therapeutics program."
This press release contains forward-looking statements that reflect the Company's current expectation regarding future events. Actual events could differ materially and substantially from those projected herein and depend on a number of factors. Certain statements in this release, and other written or oral statements made by NanoViricides, Inc. are "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. You should not place undue reliance on forward-looking statements since they involve known and unknown risks, uncertainties and other factors which are, in some cases, beyond the Company's control and which could, and likely will, materially affect actual results, levels of activity, performance or achievements. The Company assumes no obligation to publicly update or revise these forward-looking statements for any reason, or to update the reasons actual results could differ materially from those anticipated in these forward-looking statements, even if new information becomes available in the future. Important factors that could cause actual results to differ materially from the company's expectations include, but are not limited to, those factors that are disclosed under the heading "Risk Factors" and elsewhere in documents filed by the company from time to time with the United States Securities and Exchange Commission and other regulatory authorities. Although it is not possible to predict or identify all such factors, they may include the following: demonstration and proof of principle in pre-clinical trials that a nanoviricide is safe and effective; successful development of our product candidates; our ability to seek and obtain regulatory approvals, including with respect to the indications we are seeking; the successful commercialization of our product candidates; and market acceptance of our products.
NanoViricides, Inc. is a development stage company that is creating special purpose nanomaterials for viral therapy. The Company's novel nanoviricide(R) class of drug candidates are designed to specifically attack enveloped virus particles and to dismantle them. The Company is developing drugs against a number of viral diseases including H1N1 swine flu, H5N1 bird flu, seasonal Influenza, HIV, oral and genital Herpes, viral diseases of the eye including EKC and herpes keratitis, Hepatitis C, Rabies, Dengue fever, and Ebola virus, among others.
About the Dr. Eva Harris' Laboratory at the University of California, Berkeley
The Harris Laboratory in the Division of Infectious Diseases in the School of Public Health at the University of California, Berkeley has developed a multidisciplinary approach to study the molecular virology, pathogenesis, and epidemiology of dengue, the most prevalent mosquito-borne viral disease in humans. Their work addresses viral and host factors that modulate disease severity. One major research focus has been the development of a mouse model to study viral tropism and pathogenesis, investigate the immune response to dengue virus infection, and evaluate candidate anti-viral therapeutics. Dr. Harris' field work focuses on laboratory-based and epidemiological studies of dengue in endemic Latin American countries, particularly in Nicaragua, where ongoing projects include clinical and biological studies of severe dengue, a pediatric cohort study of dengue and influenza transmission in Managua, and a project on evidence-based, community-derived interventions for prevention of dengue via control of its mosquito vector.
