Novavax announced the initiation of its Phase 2b/3 Hummingbird™ clinical trial. The trial will evaluate the safety, effectiveness (immunogenicity), and efficacy of two doses of the Novavax COVID-19 vaccine (NVX-CoV2373) in younger children aged six months through 11 years, followed by a booster at six months after the primary vaccination series.
"We are excited to begin the Hummingbird trial to study Nuvaxovid's efficacy in children as young as six months through age 11," said Stanley C. Erck, President and Chief Executive Officer, Novavax. "With a successful trial, we may have the opportunity to offer our COVID-19 vaccine to all age groups aged six months and older for protection against this ongoing pandemic."
The trial will assess the Novavax COVID-19 vaccine in infants (six through 23 months of age), toddlers (two through five years) and children (six through 11 years). The trial is an age de-escalation trial and age groups will be tested sequentially. Participants have begun dosing in the six to 11-year-old age group. The trial will also have sentinel cohorts in each age group and cohort progression and age-de-escalation will occur after safety review.
The trial will seek to enroll 3,600 participants in the US, Mexico, Colombia, Argentina, Spain, UK, South Africa, Philippines, and Brazil. Initial results are expected in Q1 2023.
