SUPPLEMENTARY INFORMATION: Technology description follows: SARS-CoV-2 Spike Fused to Hepatitis B Surface Antigen Description of Technology: The emergence of the SARS-CoV-2 virus and its immune-escaping variants have led to global COVID-19 pandemic/endemic, underscoring the urgent need for effective vaccines with strong and durable immune responses. Researchers at the Vaccine Research Center (VRC) of the National Institute of Allergy and Infectious Diseases (NIAID) used a novel approach to SARS-CoV-2 vaccine development by leveraging hepatitis B surface antigen (HBsAg), which has a proven track record of safety and efficacy in hepatitis B vaccines. They designed fusion protein constructs comprised of HBsAg linked by a series of glycine-serine residues to the prefusion stabilized spike protein of SARS-CoV-2. These constructs can self-assemble into nanoparticles in mammalian cells and bind monoclonal antibodies (mAbs) that are specific to different domains of the SARS-CoV-2 spike. The nanoparticles elicit potent and durable immune responses including neutralizing antibody [[Page 15600]] response. In vitro and in vivo experiments demonstrate that this nanoparticle platform has the potential for use as a robust SARS-CoV-2 vaccine. This technology is available for licensing for commercial development in accordance with 35 U.S.C. 209 and 37 CFR part 404, as well as for further development and evaluation under a research collaboration. Potential Commercial Applications:Novel SARS-CoV-2 vaccine and universal vaccines against coronavirus Vaccine development against other viral pathogens such as HIV and flu Competitive Advantages: Higher potency, potentially longer protection compared to other SARS-CoV-2 vaccine formulations. Potent immune response via genetic delivery, including DNA and RNA immunization. Improved immunogenicity compared to other nanoparticle or virus-like-particle (VLP)-based vaccines for SARS-CoV-2 spike protein. Development Stage: Pre-Clinical. Inventors: Drs. John Mascola, Cuiping Liu, Wei Shi, Amarendra Pegu, Lingshu Wang, Wing-Pui Kong, all of NIAID. Publication: Liu, C., Wang, L., Merriam, J.S. et al.
