Vaxart Reports First Quarter 2021 Financial Results and Provides Business Update

  • Vaxart to advance three oral tablet COVID-19 vaccine candidates to the clinic: VXA-CoV2-1 (includes both the S and the N proteins) into Phase II and two S-only constructs into Phase I/II

  • Four clinical trials of the oral norovirus vaccine candidate to be initiated in 2021

  • Cash, cash equivalents, and marketable securities of $177.3 million as of March 31, 2021

SOUTH SAN FRANCISCO, Calif., May 03, 2021 (GLOBE NEWSWIRE) — Vaxart, Inc. (Nasdaq: VXRT), a clinical-stage biotechnology company developing oral vaccines that are administered by room-temperature stable tablet rather than by injection, today reported financial results for the first quarter ended March 31, 2021 and provided a corporate update. As part of this update, the Company announced that it plans to initiate several clinical and pre-clinical COVID-19 vaccine studies as it continues the development of its multivariant COVID-19 vaccine candidate portfolio.

“The recent results of a poll we commissioned suggested that as many as 19 million more Americans would decide to get vaccinated against COVID-19 if the vaccine was administered as a pill instead of a needle injection — a number we expect to be much higher worldwide, particularly given the distribution advantages of a room-temperature stable tablet. That alone could potentially make a significant global impact,” said Andrei Floroiu, Chief Executive Officer of Vaxart.

“Additionally, we expect our vaccine to have a different profile – on safety, tolerability, and immunogenicity – than those of injectable vaccines,” added Floroiu. “Our vaccines employ a novel mechanism of action — validated by clinical results against flu — that is very different than those of injectable vaccines, thus offering the potential to complement, if not replace, injectable vaccines.”

Recent Business Highlights:

Clinical and Pre-Clinical:



Norovirus is a highly infectious illness that affects around 20 million Americans annually, and it has an annual economic impact of approximately $10.5 billion in the United States. Vaxart plans to progress its oral norovirus vaccine program with the initiation of four clinical trials in 2021:

  • A booster dose in a subset of subjects who participated in the prior Phase 1b bivalent study will assess the safety, tolerability and immunogenicity of this dose approximately 18 months after initial dosing. Dosing is completed, and results will be reported by mid-year 2021.

  • A booster ranging trial designed to assess the safety, tolerability, immunogenicity, and efficacy of 2-dose vaccination schedule (4, 8, and 12 weeks apart) started recently.

  • An age escalation trial in subjects over 65 years old designed to assess the safety, tolerability, immunogenicity, and efficacy of 2 dose levels of vaccine with a 2-dose vaccination schedule (4 weeks apart) planned to start in 3Q 2021.

  • A Phase 2 challenge study is planned to start later this year.

Vaxart also released data from a poll it commissioned, which surveyed 1,500 subjects and found that as many as an additional 19 million Americans would decide to get vaccinated against COVID-19 if they had an oral tablet option.

  • The poll suggested as many as an additional 4 million Black, 3 million rural, 2 million Hispanic and 1.5 million Asian Americans would take a pill COVID-19 vaccine.

  • 7 in 10 said they would prefer taking a vaccine pill rather than getting injected with a vaccine.


  • Vaxart appointed David Wheadon, M.D., to its Board of Directors. Dr. Wheadon is a health policy leader and physician with more than three decades of global experience in the pharmaceutical industry coordinating the interests of public companies, trade groups, and regulators.

  • Rajesh Kapoor, Ph.D., joined Vaxart as the SVP Quality. Dr. Kapoor brings 30 years of domestic and international experience with small and large companies covering aseptic and non-aseptic Quality Operations encompassing vaccines, biologics, drugs, APIs, clinical Quality Assurance, and radiopharmaceuticals.

Cash, Cash Equivalents, and Marketable Securities Balance:

  • Vaxart ended the quarter with cash, cash equivalents, and available-for-sale debt securities of $177.3 million, compared to $126.9 million as of December 31, 2020. The increase was primarily due to receipts of $65.7 million from the Company’s $250 million at-the-market facility entered into in October 2020 and $1.9 million from the exercise of warrants and options, partially offset by $16.6 million of cash used in operations and $0.6 million spent on property and equipment.

Financial Results for the Three Months Ended March 31, 2021:

  • Vaxart reported a net loss of $16.0 million for the first quarter of 2021 compared to $1.3 million for the first quarter of 2020. Net loss per share for the first quarter of 2021 was $0.14, compared to a net loss of $0.02 in the first quarter of 2020. The increase in net loss per share was due to the increase in net loss partially offset by the increase in the weighted average number of shares outstanding.

  • Revenue for the first quarter of 2021 was $506,000 compared to $2.9 million in the first quarter of 2020. The decrease was principally due to a reduction in royalty revenue related to Inavir sales in Japan as a result of abnormally low incidences of seasonal influenza.

  • Research and development expenses were $10.1 million for the first quarter of 2021 compared to $1.5 million for the first quarter of 2020. The increase was mainly due to manufacturing and clinical trial expenses related to the COVID-19 and norovirus vaccine candidates.

  • General and administrative expenses were $5.9 million for the first quarter of 2021 compared to $2.0 million for the first quarter of 2020. The increase was mainly due to higher legal and insurance expenses, and an increase in headcount and related costs.
