Two Sanofi combination vaccine candidates for prevention of influenza, COVID gets USFDA Fast Track designation
Paris: The US Food and Drug Administration (USFDA) has granted Fast Track designation to two Sanofi combination vaccine candidates to prevent influenza and COVID-19 infections in individuals 50 years of age and older. Both candidates combine two already licensed and authorized vaccines with proven efficacy through randomized controlled studies, and with favorable tolerability.
The first combination vaccine candidate (NCT06695117) consists of the influenza protein-based trivalent vaccine Fluzone High-Dose combined with the adjuvanted recombinant Novavax COVID-19 vaccine. The second candidate (NCT06695130) combines the influenza recombinant protein-based trivalent vaccine Flublok with the Novavax COVID-19 vaccine.
Both Fluzone High-Dose and Flublok have been proven to prevent more influenza infections in older adults than standard-dose influenza vaccines in pivotal randomized clinical studies. Additionally, in real-world evidence studies they have demonstrated significant and consistent reductions in flu-related hospitalizations. The Novavax COVID-19 vaccine has been shown to have a better tolerability profile than currently available mRNA COVID-19 vaccines when administered as a booster dose. It has also demonstrated high efficacy against COVID-19 as primary vaccination in two pivotal phase 3 studies.
