ROCKVILLE, Md., Dec. 3, 2012 (GLOBE NEWSWIRE) -- Novavax, Inc. (Nasdaq:NVAX) today announced that the journal PLOS ONE (http://dx.plos.org/10.1371/journal.pone.0050852) published data from a preclinical study of its recombinant nanoparticle vaccine candidate against respiratory syncytial virus (RSV), demonstrating efficacy and safety in a well-established animal model. These data indicated that the use of an RSV fusion (F) protein nanoparticle vaccine that induced high levels of specific neutralizing antibodies protected animals from both RSV replication and disease.
"The data from this preclinical model demonstrated the potential of our RSV F nanoparticle vaccine candidate to elicit the level and type of immunity required to protect humans as measured by virus neutralization activity," said Gale Smith, PhD, Novavax' Vice President of Vaccine Development. "Furthermore, our RSV vaccine candidate showed no sign of immunological disease enhancement which has plagued RSV vaccine development to date."
Severe RSV infection is the leading cause of infant hospitalization in the U.S., and globally there are 64 million cases and 160,000 deaths annually. Approximately one-half of all infants are infected with RSV during the first year of life, and nearly all children are infected at least once by the time they reach their second birthday. RSV also accounts for significant morbidity and mortality among the elderly, and adults with cardio-pulmonary compromise. There is currently no approved RSV prophylactic vaccine to address this critical unmet health care need.
"This publication describes important supportive evidence of the potential safety and efficacy of our RSV nanoparticle vaccine, and the rationale for the choice of the specific vaccine antigen," said Dr. Gregory Glenn, MD and Chief Scientific Officer for Novavax. "We have completed a Phase I trial and recently initiated two separate dose-ranging clinical trials of the RSV F nanoparticle vaccine candidate in the elderly (Phase I) and in women of child-bearing age (Phase II). These preclinical observations are consistent with the promising safety and immunogenicity seen in our clinical trials reported to date and suggest that this vaccine should continue to be developed."
