NanoViricides, Inc. Reports Oral FluCide™ Is Highly Effective Against H3N2 Influenza A Virus and Superior to Tamiflu® based on Increased Survival in a Lethal Influenza Animal Model
WEST HAVEN, Conn.--(BUSINESS WIRE)-- NanoViricides, Inc. (OTCBB: NNVC) (the "Company") reported today that its oral FluCide™ drug candidates demonstrated dramatically improved survival in animals administered a lethal dose of the H3N2 influenza A virus. Animals treated with the oral anti-influenza nanoviricide drug candidates survived for much longer as compared to Tamiflu® treated animals.
Animals treated with the best of the oral FluCide™ nanoviricide drug candidates survived 15.6 days while the animals treated with oral Tamiflu survived only 9.6 days. The control animals died within 5 days. The Company has previously reported that animals treated with these same oral anti-influenza nanoviricides protected mice infected with the H1N1 influenza A virus and were similarly substantially superior to oral oseltamivir (Tamiflu).
This is the first demonstration of efficacy of the Company's FluCide drug candidates against a completely unrelated type of influenza A virus (viz. H3N2) in contrast to the H1N1 Influenza A virus that the Company has used for its recent development work leading to its pre-IND application with the US FDA.
"This demonstration is a key finding along the way to establish that our FluCide drug candidates are indeed broad-spectrum," said Anil R. Diwan, PhD, President of the Company, adding, "and we are very pleased that their effectiveness levels are substantially superior to Tamiflu."
The Company has recently established oral effectiveness of its anti-influenza drug candidates in an H1N1 influenza A lethal infection mouse model. The Company believes that this may be the first ever targeted nanomedicine that is orally effective.
The Company intends to develop data about effectiveness of its drug candidates against certain unrelated influenza A viruses using both cell culture studies and animal models in a reasonable manner. These data will be needed as part of the IND application that the Company is working on. An IND application will be required for the Company to enter into human clinical trials.
H3N2 influenza virus is one of the multiple sub-types of influenza A that cause seasonal epidemics. According to the CDC, influenza causes approximately 36,000 deaths every year in the U.S. alone. The Hong Kong Flu pandemic of 1968-1969, which killed an estimated one million people worldwide, was caused by a variant strain of H3N2. The Company believes an orally administered nanoviricide that protect against multiple influenza virus sub-types would be effective in season after season of influenza epidemics. Such a highly effective, broad-spectrum anti-influenza drug is widely anticipated to be highly successful.
The Company believes that the anti-influenza drug candidates it has developed are broad-spectrum, i.e. they should work against most if not all of influenza viruses. This is because, in spite of mutations and antigenic drift, all influenza viruses bind to the same cell surface receptor called sialic acid, and the Company has developed small chemical ligands that mimic this receptor, to attack the influenza viruses. These ligands are chemically attached to the Company's polymeric micelle backbones that mimic the cell membrane, to create the nanoviricides. The Company has previously shown effectiveness of its very early anti-influenza drug candidates against two different strains of H5N1 Bird Flu virus in cell culture studies. The Company has since then improved the ligands as well as the chemistries as reported from time to time.
The studies were conducted by Dr. Krishna Menon, PhD, VMD, MRCS, at KARD Scientific, MA. One hundred thousand virus particles of Influenza A Strain A/W/67 (H3N2 virus) were aspirated directly into the lungs of mice. The same quantity of virus infection was repeated at 22 hrs. This influenza model was designed to be uniformly fatal in 100% of the infected, untreated animals within 5 days after infection. Treatment with the FluCide drug candidates or Tamiflu® (Roche) commenced 24 hours after the first viral infection.
Additional clinically important parameters including viral load, lung histopathology, and development of anti-influenza antibodies are being analyzed to confirm the therapeutic potential of the oral FluCide drug candidates against H3N2. The results of these investigations will be reported as they become available.
