Vaxart Provides Business Update and Reports First Quarter 2023 Financial Results  

  • On track to report key top line data from two Phase 2 norovirus vaccine studies mid-year and in Q3 2023
  • Continue to anticipate cash runway into Q2 2024
  • Conference call today at 4:30 p.m. ET

SOUTH SAN FRANCISCO, Calif., May 04, 2023 (GLOBE NEWSWIRE) -- Vaxart, Inc. (NASDAQ: VXRT) today announced its business update and financial results for the first quarter of 2023.

“During the first quarter, we continued to advance our norovirus oral pill vaccine program and remain on track to report two important clinical data readouts in 2023,” said Andrei Floroiu, Vaxart’s Chief Executive Officer. “Norovirus represents a significant public health issue with no approved vaccine, and it places a tremendous economic burden on society. More than 21 million people are infected in the U.S. each year, creating an annual disease burden of more than $10 billion domestically.

“Our innovative approach to addressing this unmet medical need is supported by data from six completed norovirus clinical trials that have enrolled nearly 350 subjects. These data have shown immune responses from our vaccine to be strong, long-lasting, comparable to natural infection and similar in both elderly and young populations,” Mr. Floroiu added.

Recent Business Highlights

Norovirus Vaccine Developments

  • In April 2023, Vaxart presented previously published research from its norovirus oral vaccine program at the World Vaccine Congress in Washington, D.C. Dr. James F. Cummings, Vaxart’s Chief Medical Officer, exhibited findings demonstrating potent serum and mucosal immune responses to norovirus with Vaxart’s oral bivalent norovirus vaccine candidate.
  • In March 2023, Vaxart provided a detailed overview and reviewed data from its norovirus oral pill vaccine program during presentations at its sponsored norovirus Key Opinion Leader (KOL) event. Featured experts on the disease explained the current disease burden posed by norovirus, as well as its significant economic and societal costs that impact the U.S. on an annual basis. A replay of the KOL event is available here.
  • In February 2023, Vaxart initiated a Phase 2 dose-ranging study of its bivalent norovirus oral vaccine candidate and expects to report topline data from this study in mid-2023.

COVID-19 Vaccine Developments

  • Vaxart continues to conduct preclinical development of novel constructs for its COVID-19 oral vaccine candidate. Based on the mucosal cross-reactivity data reported to date in Vaxart’s clinical studies of its COVID-19 vaccine candidates, the Company believes it may be able to create an oral pan-betacoronavirus vaccine. A pan-betacoronavirus vaccine may provide more effective and flexible protection, positioned to prevent both current and emerging coronavirus threats and other beta-coronaviruses, making it a valuable tool for pandemic preparedness.
  • During the World Vaccine Congress, Dr. Sean Tucker, Vaxart’s Founder and Chief Scientific Officer, presented previously published data from Vaxart studies demonstrating the platform’s ability to block transmission and boost existing COVID-19 vaccines by oral tablet vaccination.

Anticipated 2023 Clinical Milestones

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

  • Report topline data from the ongoing Phase 2 dose-ranging study of Vaxart’s bivalent norovirus vaccine candidate in mid-2023.
  • Report topline data from the ongoing Phase 2 challenge study of Vaxart’s monovalent norovirus vaccine candidate in Q3 2023.
  • Initiate 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 March 31, 2023

  • Vaxart ended the first quarter of 2023 with cash, cash equivalents, restricted cash and marketable securities of $71.8 million, compared to $95.7 million as of December 31, 2022. The decrease was primarily due to cash used in operations.
  • Vaxart reported a net loss of $25.1 million for the first quarter of 2023, compared to $25.1 million for the first quarter of 2022. Net loss per share for the first quarter of 2023 was $0.19, compared to a net loss of $0.20 per share in the first quarter of 2022.
  • Revenue for the first quarter of 2023 was $675,000, compared to $85,000 in the first quarter of 2022. The increase was due to revenue recognition for services rendered in relation to Vaxart’s grant from the Gates Foundation and higher royalty revenue from sales of Inavir in Japan.
  • Research and development expenses were $19.6 million for the first quarter of 2023, compared to $18.2 million for the first quarter of 2022. The increase was mainly due to increases in headcount and related costs and clinical trial expenses related to the Company’s norovirus vaccine candidate.
  • General and administrative expenses were $6.6 million for the first quarter of 2023, compared to $6.7 million for the first quarter of 2022.
