Novavax’s COVID-19-Influenza Combination and Stand-alone Influenza Vaccine Candidates Showed Robust Immune Responses in Initial Cohort of a Phase 3 Trial
Novavax, Inc. (Nasdaq: NVAX) today announced results of the initial cohort of its COVID-19-Influenza Combination (CIC) and stand-alone trivalent hemagglutinin nanoparticle seasonal influenza (tNIV) Phase 3 trial that showed both the CIC and flu vaccine candidates induced immune responses similar to licensed comparators Nuvaxovid® and Fluzone HD, respectively. This cohort was designed to provide descriptive data on three flu strains (H1N1, H3N2, B) and SARS-CoV-2 (COVID-19) to inform a future registrational Phase 3 program. Both stand-alone flu and CIC vaccine candidates induced robust immune responses to the vaccine strains (2.4-5.7-fold over baseline). Both vaccine candidates were well tolerated and saw reactogenicity comparable to authorized comparators. Nearly all (>98%) solicited adverse events were mild or moderate in severity. This descriptive trial was designed to evaluate the safety and immunogenicity of the CIC and stand-alone flu vaccine candidates compared to Nuvaxovid and…
