Conference call today at 4:30 p.m. ET

SOUTH SAN FRANCISCO, Calif., Aug. 03, 2023 (GLOBE NEWSWIRE) -- Vaxart, Inc. (Nasdaq: VXRT) today announced its business update and financial results for the second quarter of 2023.

“During the second quarter, we continued to advance our oral pill vaccine programs and deliver on our planned timelines for this year,” said Andrei Floroiu, Vaxart’s Chief Executive Officer. “Positive preliminary topline data from our Phase 2 bivalent norovirus vaccine candidate builds on the growing body of evidence supporting Vaxart’s platform and the potential advantages of mucosal vaccination.

“We are excited about the potential for our norovirus vaccine program, the only one formulated for oral administration and delivery to the gastrointestinal system,” Mr. Floroiu continued. “We anticipate reporting topline data from our GI.1 norovirus challenge study during the third quarter, which will help inform the next steps for this program.”

Recent Business Highlights

Norovirus Vaccine Developments

• In July 2023, Vaxart reported positive preliminary topline data from the Phase 2 dose-ranging clinical trial of its oral pill bivalent norovirus vaccine candidate.
  • The study met all primary endpoints, as the vaccine was well-tolerated with robust immunogenicity.
  • Data from this study and from Vaxart’s forthcoming norovirus challenge study will help inform selection of the dose to be used in a larger Phase 2b study. These studies are expected to enable an End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) to discuss plans for a Phase 3 trial.
  • Vaxart now has obtained robust immunogenicity data from seven clinical trials in both young adults and elderly populations.
  • These trials have shown a favorable safety profile, as the vaccine candidates have been well tolerated with no vaccine related serious adverse events.
    

COVID-19 Vaccine Developments

• Vaxart continues to progress its COVID-19 vaccine program and believes the cross-reactivity of the current constructs suggests a pathway for developing a pan-betacoronavirus vaccine. The Company is assessing next steps.
  

Anticipated 2023 Clinical Milestones
Vaxart continues to make progress on its anticipated milestones in 2023:

• Topline data from the ongoing Phase 2 challenge study of Vaxart’s GI.1 norovirus vaccine candidate is expected in Q3 2023.
  
• Initiation of a Bill & Melinda Gates Foundation-funded clinical trial to evaluate the ability of Vaxart’s norovirus vaccine candidate to induce antibodies in breast milk and transfer of antibodies to young infants.
  

Financial Results for the Three Months Ended June 30, 2023

• Vaxart ended the second quarter of 2023 with cash, cash equivalents, restricted cash and marketable securities of $67.9 million, compared to $71.8 million as of March 31, 2023. The decrease was primarily due to cash used in operations, which was partially offset by $13.6 million of net proceeds from a public offering completed in June 2023. The offering extends the Company’s expected cash runway into the third quarter of 2024.
• Vaxart reported a net loss of $22.6 million for the second quarter of 2023, compared to $29.4 million for the second quarter of 2022. Net loss per share for the second quarter of 2023 was $0.16, compared to a net loss of $0.23 per share in the second quarter of 2022.
• Revenue for the second quarter of 2023 was $1.4 million, compared to no revenue in the second quarter of 2022. Revenue in the second quarter of 2023 was primarily from revenue recognized for work performed under Vaxart’s grant from the Bill & Melinda Gates Foundation.
• Research and development expenses were $18.8 million for the second quarter of 2023, compared to $19.9 million for the second quarter of 2022. The decrease was primarily due to decreases in manufacturing costs, personnel-related costs and clinical trial expenses related to the Company’s COVID-19 vaccine candidates, partially offset by increased clinical trial expenses related to its norovirus vaccine candidates.
• General and administrative expenses were $5.6 million for the second quarter of 2023, compared to $9.3 million for the second quarter of 2022. The decrease is primarily due to a decrease in litigation settlement cost, legal and professional fees and directors' and officers' insurance, partially offset by an increase in personnel stock-based costs.
