• Lo believes the data generated to date are compelling and demonstrate their vaccines potential to address the impact of infectious diseases on vulnerable populations.

Industry Context

This announcement is relevant to the broader biotechnology and vaccine development industry, particularly in the areas of oral vaccine delivery and infectious disease prevention. The positive results from the norovirus trial and the progress on the COVID-19 vaccine position Vaxart as a potential player in the market.

Comparison to Industry Standards

• Vaxart's oral vaccine platform is a differentiator compared to traditional injectable vaccines, aligning with a trend towards more convenient vaccine administration.
• The reported antibody responses in the norovirus trial are promising, but further data from Phase 2b studies will be needed to compare efficacy with other norovirus vaccine candidates.
• The initiation of a Phase 2b study for the COVID-19 vaccine against an approved mRNA vaccine is a standard approach for evaluating new vaccine candidates.
• The company's financial position, with a cash runway into late fourth quarter of 2024, is a concern compared to larger, more established pharmaceutical companies with more substantial cash reserves.
• Companies like Moderna and Pfizer have already commercialized mRNA COVID-19 vaccines, making Vaxart's oral vaccine a late entrant to the market, but with a different delivery method.

Stakeholder Impact

• Shareholders may be encouraged by the positive clinical trial results and progress on vaccine development.
• Employees may be motivated by the company's progress and potential for future success.
• Customers (potential patients) may benefit from the development of new oral vaccines.
• Suppliers and creditors may be impacted by the company's financial performance and future funding needs.

Next Steps

• Vaxart plans to initiate a Phase 2b study for its XBB COVID-19 vaccine as early as the second quarter of 2024.
• The company will meet with the FDA in mid-2024 to discuss data on correlates of protection for its norovirus vaccine.
• Vaxart may conduct a Phase 2b study and a GII.4 challenge study for its norovirus vaccine.
