Novavax, Inc: Novavax Completes Enrollment of Pivotal Phase 3 Trial of the RSV F Vaccine in Older Adults

GAITHERSBURG, Md., Dec. 14, 2015 (GLOBE NEWSWIRE) -- Novavax, Inc. (Nasdaq:NVAX), a clinical-stage vaccine company focused on the discovery, development and commercialization of recombinant nanoparticle vaccines and adjuvants, today announced complete target enrollment of the pivotal Phase 3 clinical trial, known as Resolve(TM), of its respiratory syncytial virus F-protein nanoparticle vaccine candidate (RSV F Vaccine) in older adults (60 years of age and older).

The  Resolve trial  is a randomized, observer-blinded, placebo-controlled trial of 11,850 older adults at 60 sites in the United States. All participants have been enrolled and vaccinated in advance of the 2015-16 RSV season, and top-line results are expected in the second half of 2016. The primary efficacy objective of the Resolve trial is the prevention of moderate-severe RSV-associated lower respiratory tract disease, as defined by the presence of multiple lower respiratory tract symptoms. 

"Complete enrollment of this 11,850 participant trial in only five weeks is a significant achievement and underscores the strength of our clinical operations and management teams, as well as the support of our numerous clinical trial sites and our dedicated key opinion leaders," said Stanley C. Erck, President and CEO. "Our two Phase 3 trials of the RSV F Vaccine, Resolve and Prepare(TM), signal Novavax' commitment to bring this groundbreaking vaccine to market for the populations most affected by RSV. We look forward to releasing top-line data from the Resolve trial in the third quarter of 2016."
