Nanoviricides Reports Significant Efficacy of Anti-Dengue Drug Candidates in Initial Studies

Published on June 21, 2010 at 8:22 AM

NanoViricides, Inc. (OTC BB: NNVC.OB) (the "Company") reports that its anti-Dengue drug candidates demonstrated significant protection in the initial animal survival studies of Dengue virus infection. The studies were performed in the laboratory of Dr. Eva Harris, Professor of Infectious Diseases at the University of California, Berkeley (UC Berkeley).

Treatment with one of the anti-Dengue nanoviricides® led to survival of 50% of the animals for the duration of study in the ADE model. In addition, animals treated with several anti-Dengue nanoviricides survived longer than the control animals treated with vehicle alone. This ADE model of infection is uniformly fatal in 100% of the infected animals within 5 days after infection.

Dr. Harris is a leading researcher in the field of dengue viruses. Her group has developed a unique animal model for the most severe and potentially fatal form of Dengue virus infection in humans, Dengue Hemorrhagic Fever/Dengue Shock Syndrome (DHF/DSS). The model emulates the “Antibody-Dependent Enhancement (ADE)” of Dengue virus infection in humans that is believed to lead to DHF/DSS.

“We are very excited about these results,” said Professor Harris, adding, “This is a very important demonstration of a viable drug candidate leading to significant survival in the ADE model of Dengue virus infection. I believe nanoviricides show great promise in our model and against severe dengue disease.”

“The first screen has already shown that we are on the right path,” said Anil R. Diwan, PhD, President of the Company, adding, “We believe we have at least one potential drug candidate against Dengue now.”

“We have been able to produce an effective drug candidate against dengue in a very short time,” said Eugene Seymour, MD, MPH, Chief Executive Officer of the Company, adding, “This demonstrates the strength of the nanoviricides technology platform.”

The Company has previously reported significant efficacy of several nanoviricides in two different in vitro (cell culture) tests against dengue virus type 2 conducted by Professor Harris’ Lab. Some of these nanoviricides were tested in vivo in the present study.

Dengue is receiving significant international attention as it threatens over 40% of the world population, according to WHO. Dengue cases with significant fatality rates have started rising in tropical countries this year already, as demonstrated by reports from India, Sri Lanka, Indonesia, Philippines, Cambodia, and Colombia, among others. Dengue is endemic in Asia, Mexico, the Caribbean, Central America and many countries in South America. Dengue virus infections have occurred in the southern US states, including a current outbreak in Key West, and travel leads to sporadic cases of dengue in the US.
