(Nasdaq: NVAX), a biotechnology company dedicated to developing and commercializing next-generation vaccines for serious infectious diseases, today announced initial results from the Phase 1/2 clinical trial of its COVID-Influenza Combination Vaccine (CIC). The CIC combines Novavax' COVID-19 vaccine, NVX-CoV2373, and its quadrivalent influenza vaccine candidate. The CIC trial demonstrated that formulating the combination vaccine is feasible, well-tolerated and immunogenic.\n\"We continue to evaluate the dynamic public health landscape and believe there may be a need for recurrent boosters to fight both COVID-19 and seasonal influenza,\" said Gregory M. Glenn, M.D., President of Research and Development, Novavax. \"We're encouraged by these data and the potential path forward for a combination COVID-19-influenza vaccine as well as stand-alone vaccines for influenza and COVID-19.\"\nThe safety and tolerability profile of the combination vaccine was consistent with the stand-alone NVX-CoV2373 and quadrivalent nanoparticle influenza vaccine reference formulations in the trial. The combination vaccine was found to be generally well tolerated. Serious adverse were rare and none were assessed as being related to the vaccine.\nThe study employed descriptive endpoints, assessing safety and the immunological responses of different CIC vaccine formulations. A Design of Experiments (DOE) modeling-based approach was used to design the trial, enabling more powerful fine-tuning of dose selection of both the COVID-19 and influenza antigens for further development compared to traditional approaches. The preliminary trial results found that various CIC vaccine formulations induced immune responses in participants comparable to reference stand-alone influenza and stand-alone COVID-19 vaccine formulations (for H1N1, H3N2, B-Victoria HA and SARS-CoV-2 rS antigens). Modeling results also showed that a combined formulation ha...
