Vaxart Provides Business Update and Reports Second Quarter 2021 Financial Results

SOUTH SAN FRANCISCO, Calif., Aug. 5, 2021 /PRNewswire/ -- Vaxart, Inc. (Nasdaq: VXRT) issued its business update today for the second quarter of 2021, reporting strong forward momentum in development of oral tablet vaccines that it believes can revolutionize public health.

Vaxart, a clinical-stage biotechnology company developing oral recombinant vaccines that are administered by tablet rather than by injection, announced its business progress and provided financial results for the second quarter ended June 30, 2021.

"By any measure, Vaxart showed real forward momentum during the last quarter," CEO Andrei Floroiu said. "We strengthened our balance sheet, made major research advances, deepened our scientific knowledge, grew the company, and took the company closer to our goal of developing disruptive oral tablet vaccines that can have a material impact on the world's public health."

Recent Business Highlights

Corporate Developments

• Vaxart raised $36.2 million in net proceeds from its $250 million at-the-market facility in the three months ended June 30, 2021.
• Vaxart signed an exclusive worldwide licensing agreement with Altesa Biosciences, Inc. to allow Altesa to develop and commercialize Vaxart's Vapendavir, a clinical-stage broad spectrum antiviral.
• The licensing agreement provides for milestone payments up to $130 million and royalties for global Vapendavir sales.
• Building out the infrastructure necessary to support its groundbreaking research, Vaxart added to its management team and strengthened its research, clinical, and manufacturing groups and R&D infrastructure. The number of R&D employees grew by 36% in the quarter to 49 full-time employees.

Pre-Clinical and Clinical

Platform-Wide Developments

• Vaxart completed its first boosting study, which showed in clinical trials that its norovirus vaccine built on the VAAST™ platform can successfully boost immune responses in subjects previously vaccinated with a Vaxart oral vaccine more than a year earlier.
• The research supports the company's thesis that its oral tablet vaccines have the potential to be used annually for indications that may require a boost such as flu or COVID-19.
• The data announced that Vaxart's vaccines may not suffer from certain antibody response challenges that can occur with viral vector-based vaccines.

COVID-19 Vaccine Developments

While the nation's death and illness tolls have fallen markedly since the beginning of the last quarter, new variants such as the Delta strain continue to worry national political and health leaders. Vaxart broadened its research into the various COVID-19 strains while continuing its development of an oral tablet vaccine. Among the most significant developments in the second quarter:

• The U.S. Food and Drug Administration cleared Vaxart to move to its next phase of COVID-19 testing with a study of its next generation S-1 construct.
• Vaxart is manufacturing the vaccine necessary to start the Phase 2 clinical study of its S-Wuhan construct and expects to begin this study shortly.
• A Non-Human Primate study of the S&N construct along with S-Wuhan and S-South Africa constructs showed optimal performance by the S-Wuhan construct and also cross reactivity against all variants tested. The decision was made to the S-Wuhan vaccine construct into Phase 2.

Norovirus Vaccine Developments

Norovirus is a highly infectious illness that affects around 20 million Americans annually, with an annual economic impact of approximately $10.5 billion in the United States.

• In addition to its boosting study, Vaxart enrolled the first subjects in a Phase 1b placebo-controlled, dose-ranging, repeat dose trial investigating its oral norovirus vaccine candidate in elderly subjects aged 55 – 80 years.
• This study is designed to evaluate the safety and immunogenicity of Vaxart's candidate, which is the only clinical stage norovirus oral tablet vaccine actively being developed.

Financial Results for the Three Months Ended June 30, 2021

• Vaxart ended the quarter with cash, cash equivalents, and available-for-sale debt securities of $198.9 million, compared to $177.3 million as of March 31, 2021. The increase was primarily due to net receipts of $36.2 million from the Company's $250 million at-the-market facility entered into in October 2020 and $0.9 million from the exercise of warrants and options, partially offset by $13.2 million of cash used in operations and $2.2 million spent on property and equipment.
• Vaxart reported a net loss of $16.1 million for the second quarter of 2021 compared to $9.0 million for the second quarter of 2020. Net loss per share for the second quarter of 2021 was $0.13, compared to a net loss of $0.12 in the second quarter of 2020. The small increase in net loss per share was due to the increase in net loss being mostly offset by the increase in the weighted average number of shares outstanding.
• Revenue for the second quarter of 2021 was $112,000 compared to $523,000 in the second quarter of 2020. The decrease was principally due to the absence of royalty revenue related to Relenza sales in Japan as a result of the patent expiring and a reduction in royalty revenue related to Inavir sales in Japan as a result of lower incidences of seasonal influenza.
• Research and development expenses were $10.7 million for the second quarter of 2021 compared to $5.1 million for the second 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 $5.2 million for the second quarter of 2021 compared to $3.9 million for the second quarter of 2020. The increase was mainly due to higher insurance expenses and an increase in headcount and related costs.
