NanoBio Awarded U.S. Patent for RSV Vaccine
Broad Intellectual Property Protection Secured Through 2034
ANN ARBOR, Mich., (December 19, 2016) – NanoBio Corporation today announced the issuance of U.S. Patent No. 9,492,525 Human Respiratory Syncytial Virus (RSV) Vaccine. The patent broadly covers the composition of NanoBio’s intramuscular and intranasal RSV vaccine candidates, which combine the company’s innovative nanoemulsion (NE) adjuvant with strain L19 of RSV. Additional patent applications covering the combination of the NE adjuvant with other strains of RSV and with RSV F protein are currently being pursued.
“This critical patent strengthens NanoBio’s position as we prepare to advance our NE RSV vaccine into clinical studies,” said Dr. Ali Fattom, Senior Vice President of Vaccine Research and Development, NanoBio. “Based on our research to date, the use of whole inactivated RSV L19 in combination with our NE adjuvant elicits robust protection across multiple strains of RSV in both cotton rats and non-human primates, without evidence of safety concerns or the enhancement of disease observed with prior formalin-inactivated vaccines.”
Formulation of RSV L19 virus with NanoBio’s NE adjuvant splits and fully inactivates the virus as a result of the adjuvant’s inherent antimicrobial properties, yet the immunogenicity of L19’s native viral proteins is preserved. The resulting NE RSV vaccine incorporates all of the viral epitopes-including F, G and other proteins-enabling a potentially much broader immune response than what is elicited by subunit vaccine candidates.
Respiratory syncytial virus, commonly referred to as RSV, is a highly contagious viral disease and is one of the most common causes of bronchiolitis and pneumonia. Up to 2.5 million infections occur in the U.S. each year. It is the number one cause of childhood hospitalization globally. Nearly all children are infected with the virus at least once by the age of two to three years, and many develop pulmonary disease and/or asthma that persists throughout adult life, making them susceptible to re-infection. The disease is particularly dangerous for premature babies, children with preexisting health conditions and the elderly. RSV is responsible for 16,000 deaths each year in adults older than 65. Currently, there are no approved vaccines for RSV.
Headquartered in Ann Arbor, Michigan, NanoBio® Corporation is a privately-held biopharmaceutical company focused on developing and commercializing vaccines and anti-infective treatments derived from its patented NanoStat® technology platform. The company’s NanoStat® vaccine technology employs a novel oil-in-water nanoemulsion (NE) that can incorporate, deliver and adjuvant multiple antigen types. The NE adjuvant is effective when administered via intranasal or intramuscular vaccination. When applied intranasally, NE vaccines elicit both mucosal and systemic immunity.
NanoBio is currently developing NE vaccines for several respiratory and sexually transmitted diseases, including RSV, pertussis, pandemic influenza, anthrax, and prophylactic and therapeutic HSV2.
