Novavax, Inc. announced the initiation of a Phase 2 clinical trial of its respiratory syncytial virus F-protein nanoparticle vaccine candidate (RSV F Vaccine) in older adults (60 years of age and older). The objective of the trial is to assess safety and immunogenicity to one and two dose regimens of the RSV F Vaccine, with and without aluminum phosphate or Novavax’ proprietary Matrix-M™ adjuvant, in older adults. The trial is a randomized, observer-blinded, placebo-controlled trial designed to enroll up to 300 older adults in the Southern Hemisphere. Participants are being enrolled and vaccinated outside of the RSV season to best assess immunogenicity. Top-line results are expected in the third quarter of 2017.
