Novavax COVID vaccine Nuvaxovid gets expanded conditional marketing nod in UK for adolescents aged 12 through 17
Gaithersburg: Novavax, Inc. has announced that the Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom (UK) has granted expanded conditional marketing authorization (CMA) for Nuvaxovid (NVX-CoV2373) COVID-19 vaccine for active immunization to prevent coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in adolescents aged 12 through 17.
"As we start to prepare for a potential fall surge, we are pleased to offer the first protein-based COVID-19 vaccine to adolescents aged 12 through 17 in the U.K.," said Stanley C. Erck, President and Chief Executive Officer, Novavax. "We believe that our vaccine, developed using an innovative approach to traditional technology, may help increase adolescent vaccination rates."
The expanded CMA was based on data from the ongoing pediatric expansion of the Phase 3 PREVENT-19 trial of 2,247 adolescents aged 12 through 17 years across 73 sites in the U.S., to evaluate the safety, effectiveness (immunogenicity), and efficacy of Nuvaxovid. In the pediatric expansion, Nuvaxovid achieved its primary effectiveness endpoint and demonstrated 80% clinical efficacy overall at a time when the Delta variant was the predominant circulating SARS-CoV-2 strain in the U.S.
Preliminary safety data from the pediatric expansion showed the vaccine to be generally well-tolerated. There was no increase in reactogenicity in younger (12 to <15 years old) adolescents compared to older (15 to <18 years old) adolescents. No new safety signal was observed through the placebo-controlled portion of the pediatric expansion.
The next step for the vaccine is a policy recommendation for use from the UK Joint Committee on Vaccination and Immunisation (JCVI). Doses of Nuvaxovid will be made available for use in adolescents based on the JCVI's recommendation.
In the 12 through 17 year-old population, the Novavax COVID-19 vaccine has been granted authorization in the U.S., India, the European Union, Australia, Japan, Thailand, and New Zealand, and is actively under review in other markets.
The MHRA previously granted CMA for Nuvaxovid in adults aged 18 and older in February 2022. The vaccine is given as a primary vaccination in two doses administered 21 days apart. Novavax filed for expanded CMA for use as a booster in adults aged 18 and over in June 2022.
