Novavax Showcases Data from Expanding Vaccine Portfolio at IDWeek 2022

October 20, 2022
  • New Phase 3 PREVENT-19 data reinforce the Novavax COVID-19 vaccine's benefits as an adult booster in both younger and older adults, and with varying time intervals for the booster dose
  • Phase 1/2 trial data show COVID-19-Influenza Combination vaccine candidate induced antibody and T-cell responses against SARS-CoV-2 and homologous and heterologous influenza strains

GAITHERSBURG, Md., Oct. 20, 2022 /PRNewswire/ -- Novavax, Inc. (Nasdaq: NVAX), a biotechnology company dedicated to developing and commercializing next-generation vaccines for serious infectious diseases, will present new data from the Phase 3 PREVENT-19 trial evaluating its protein-based COVID-19 vaccine (NVX-CoV2373) as a booster in adults, including a breakdown by age and by booster dose interval (8 and 11 months) at IDWeek 2022, October 20 to 22, 2022. Novavax will also present data from the first Phase 1/2 COVID-19-Influenza Combination (CIC) vaccine dose-finding trial.

"At IDWeek 2022, we will share additional insights on the Novavax COVID-19 vaccine as an adult booster dose and show how we are further developing our portfolio with data from the first COVID-19-Influenza Combination vaccine candidate," said Gregory Glenn, M.D., President, Research and Development, Novavax.

New data will be presented from the PREVENT-19 trial, including an evaluation of the effect of age (18 to 64 years, and ≥ 65 years) and schedule on boosted immunologic response. These data showed that following a booster dose, anti-spike antibody and neutralizing responses for the original prototype strain increased significantly relative to pre-boost levels, regardless of the dosing regimen or age group across adult participants. Antibody responses against the more recent Omicron variants, including BA.1, BA.2, and BA.5, approximated those associated with protection in the PREVENT-19 trial. These data will be presented in addition to data shared earlier in the month.

In addition to the data presentations, Novavax is sponsoring a Learning Lounge session, "Using Behavioral Science to Help Understand Vaccine Hesitancy." As a Mentorship Champion of the Infectious Diseases Society of America (IDSA) Foundation, Novavax will also host the Mentorship Luncheon at IDWeek.

"Having a mentoring relationship is one of the main reasons that medical students and residents choose to pursue a career path in infectious diseases," said Stephen E. Peeler, IDSA Foundation, Executive Director. "That is why we are grateful to Novavax for their generous commitment to our growing mentorship program."
