GAITHERSBURG, Md., April 20, 2022 /PRNewswire/ -- Novavax, Inc. (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. “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.” The 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. The 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 has the potential to reduce total antigen amount by up to 50% overall, optimizing production and delivery. Both protein-based vaccines used in the trial were formulated with the patented saponin-based Matrix-M™ adjuvant to enhance the immune response and stimulate high levels of neutralizing antibodies. These data support advancement to a Phase 2 confirmation trial, expected to begin by the end of 2022. Data from the trial were presented at the World Vaccine Congress (WVC) in Washington, DC. Influenza Program Update At the WVC, Novavax also reviewed key findings from the Phase 3 trial of its stand-alone influenza candidate, previously referred to as NanoFlu, which met its primary immunogenicity endpoint. These results have previously been published in The Lancet. Authorization in the U.S. Neither NVX-CoV2373 or the influenza vaccine candidate have been authorized or approved for use in the U.S. by the U.S. Food and Drug Administration.

About the COVID-19-Influenza Combination Vaccine Phase 1/2 trial The Phase 1/2 CIC vaccine trial is evaluating a combination of Novavax’ recombinant protein-based NVX-CoV2373 and influenza vaccine candidates and patented saponin-based Matrix-M adjuvant in a single formulation. The trial will evaluate the safety, tolerability and immune response to the combination vaccine in 642 healthy adults 50 to 70 years of age. Participants will have been either previously infected with the SARS-CoV-2 virus that causes COVID-19 or vaccinated through an authorized vaccine at least eight weeks prior to enrollment. All participants will be randomly assigned to cohorts to evaluate multiple formulations and will be dosed on Day 0 and again at Day 56. The trial is being conducted in Australia at 10 sites. (ClinicalTrials.gov Identifier: NCT04961541) About NVX-CoV2373 NVX-CoV2373 is a protein-based vaccine engineered from the genetic sequence of the first strain of SARS-CoV-2, the virus that causes COVID-19 disease. NVX-CoV2373 was created using Novavax’ recombinant nanoparticle technology to generate antigen derived from the coronavirus spike (S) protein and is formulated with Novavax’ patented saponin-based Matrix-M adjuvant to enhance the immune response and stimulate high levels of neutralizing antibodies. NVX-CoV2373 contains purified protein antigen and can neither replicate, nor can it cause COVID-19. Novavax’ COVID-19 vaccine is packaged as a ready-to-use liquid formulation in a vial containing ten doses. The vaccination regimen calls for two 0.5 ml doses (5 mcg antigen and 50 mcg Matrix-M adjuvant) given intramuscularly 21 days apart. The vaccine is stored at 2°- 8° Celsius, enabling the use of existing vaccine supply and cold chain channels. Use of the vaccine should be in accordance with official recommendations. Novavax has established partnerships for the manufacture, commercialization and distribution of NVX-CoV2373 worldwide. Existing authorizations leverage Novavax’ manufacturing partnership with Serum Institute of India, the world’s largest vaccine manufacturer by volume. They will later be supplemented with data from additional manufacturing sites throughout Novavax’ global supply chain. About Matrix-M™ Adjuvant Novavax’ patented saponin-based Matrix-M adjuvant has demonstrated a potent and well-tolerated effect by stimulating the entry of antigen-presenting cells into the injection site and enhancing antigen presentation in local lymph nodes, boosting immune response. About Novavax’ Influenza Program Novavax’ influenza vaccine, previously known as NanoFlu, is a quadrivalent recombinant hemagglutinin (HA) protein nanoparticle influenza vaccine produced by Novavax in its SF9 insect cell baculovirus system. The influenza vaccine uses HA amino acid protein sequences that are the same as the recommended wild-type circulating virus HA sequences, and contains Novavax’ patented saponin-based Matrix-M adjuvant. This investigational candidate was evaluated during a controlled phase 3 trial conducted during the 2019-2020 influenza season. About Novavax Novavax, Inc. (Nasdaq: NVAX) is a biotechnology company that promotes improved health globally through the discovery, development and commercialization of innovative vaccines to prevent serious infectious diseases. The company’s proprietary recombinant technology platform harnesses the power and speed of genetic engineering to efficiently produce highly immunogenic nanoparticles designed to address urgent global health needs. NVX-CoV2373, the company’s COVID-19 vaccine, has received conditional authorization from multiple regulatory authorities globally, including the European Commission and the World Health Organization. The vaccine is also under review by multiple regulatory agencies worldwide. For more information, visit www.novavax.com and connect with us on LinkedIn.
