Vaxart Announces Fourth Quarter and Year-End 2018 Financial Results and Provides Corporate Update

SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)-- Vaxart, Inc., a clinical-stage biotechnology company developing oral recombinant vaccines that are administered by tablet rather than by injection, today announced financial results for the fourth quarter and full year ended December 31, 2018.

“As we execute on our objective of building a leading oral vaccine company, we continue to expand our understanding of the unique properties of our oral vaccine platform and the important advantages we believe it can offer over conventional injectable vaccines, particularly for mucosal pathogens such as norovirus, flu and RSV,” said Wouter Latour, M.D., chief executive officer of Vaxart. “We are focused on our lead product candidate, the first oral vaccine against norovirus, a disease with a $34 billion economic impact in high income countries including the United States, Europe and Japan. After laying the groundwork in 2018, we expect to initiate our norovirus Phase 1 bivalent study and Phase 2 monovalent challenge study during the first half of 2019. In parallel, we are advancing our first therapeutic vaccine targeting HPV-associated dysplasia and cancer toward the clinic.”

2018 Highlights:

Corporate:

• In February, Vaxart commenced trading on the Nasdaq Capital Market under the symbol “VXRT” following the closing of its merger with Aviragen Therapeutics.
• In October, at ID Week in San Francisco, the Company presented data from its H1 influenza Phase 2 challenge study demonstrating that its oral H1 flu vaccine, while providing 39% reduction in flu illness compared to 27% for Fluzone^®, protected primarily through mucosal immunity, in contrast to Fluzone which primarily protected through serum antibodies. This finding provides evidence that Vaxart’s oral vaccines may deliver better protection against mucosal pathogens than injectable vaccines.
• In July, Vaxart announced the publication of the comprehensive results of the previously disclosed Phase 1 clinical trial with its norovirus oral tablet vaccine in the Journal of Clinical Investigation Insight. As reported in the article, the vaccine generated robust systemic and mucosal immune responses, including mucosal IgA, memory B cells, and serum blocking antibody titers (BT50), all potential correlates of protection.
• In October at the 32^nd International Papillomavirus Conference, the Company presented preclinical data on its human papillomavirus (HPV) vaccine trial. The Vaxart HPV vaccine created CD8 tumor-infiltrating T cells and eliminated or significantly reduced the majority of tumors with or without a checkpoint inhibitor.
• In June, the Company announced the publication of preclinical results from its oral F-protein based Respiratory Syncytial Virus (RSV-F) vaccine in Vaccine. As described in the article, the oral RSV-F vaccine candidate provided complete sterilizing protection against RSV infection in the cotton rat challenge model at the target dose.

Financial Results for the Three Months and Year Ended December 31, 2018

• Vaxart reported a net loss of $4.9 million for the fourth quarter of 2018 compared to a net loss of $1.1 million for the fourth quarter of 2017. For the year ended December 31, 2018, the net loss was $18.0 million compared to a net loss of $9.6 million for 2017.
• Vaxart ended the year with cash and cash equivalents of $11.5 million compared to $17.9 million at September 30, 2018. The decrease was primarily due to cash used in operations.
• Revenue for the quarter was $1.8 million compared to $0.8 million in the fourth quarter of 2017. The increase was due to royalty revenue resulting from our merger with Aviragen, offset by lower revenues from the contract with BARDA, which ended on September 30, 2018.
• Research and development expenses were $4.5 million for the quarter compared to $1.9 million for the fourth quarter of 2017. The increase was mainly due to higher clinical and manufacturing costs incurred in the Company’s norovirus program and amortization of intangible assets acquired in the merger with Aviragen, offset by lower expenditures incurred under the BARDA contract.
• General and administrative expenses were $1.2 million for the quarter compared to $1.5 million for the fourth quarter of 2017. The decrease was a result of significant one-off costs incurred in the 2017 period in connection with the merger with Aviragen.
