Vaxart (VXRT): A Trailblazer in Oral Vaccine Innovation

Vaxart, Inc. (VXRT) is a clinical-stage biotechnology company leading the charge in developing a transformative oral vaccine platform. With a diverse pipeline targeting major infectious diseases and a steadfast commitment to improving global public health, Vaxart has emerged as a pioneering force in the pharmaceutical industry.

Company Background

Founded in 2004 and headquartered in South San Francisco, California, Vaxart has undergone a remarkable journey of innovation and progress. The company was originally incorporated as West Coast Biologicals, Inc. before changing its name to Vaxart, Inc. in 2007 and reincorporating in Delaware. In February 2018, Vaxart completed a reverse merger with Aviragen Therapeutics, Inc., solidifying its position as a publicly-traded entity. Through this merger, Vaxart acquired two royalty-earning products, Relenza and Inavir, as well as three Phase 2 clinical stage antiviral compounds. However, the company later discontinued independent development of these antiviral compounds, opting instead to enter into an exclusive worldwide license agreement with Altesa Biosciences, Inc. in July 2021 for one of the compounds, Vapendavir.

Early Challenges and Achievements

Vaxart's early years were marked by significant challenges, including substantial financial losses from 2019 to 2022. In 2020, the company recorded a $4.25 million impairment charge related to the developed technology for Inavir. Additionally, Vaxart faced legal hurdles, including a consolidated securities class action lawsuit filed in 2020, which was partially settled in 2022. Despite these obstacles, the company persevered in advancing its proprietary oral vaccine platform. A notable achievement came in 2018 when Vaxart completed a Phase 2 challenge study of its H1N1 flu vaccine candidate, funded through a $15.7 million contract with the Biomedical Advanced Research and Development Authority (BARDA). The study results were encouraging, showing that Vaxart's oral tablet vaccine candidate reduced clinical disease by 39% relative to placebo.

Proprietary Technology Platform

Vaxart's proprietary VAAST (Vector-Adjuvant-Antigen Standardized Technology) platform has been the driving force behind its success. This innovative approach aims to generate broad and durable immune responses, potentially protecting against a wide range of infectious diseases. Unlike traditional injectable vaccines, Vaxart's investigational vaccines are administered using a room-temperature-stable tablet, offering enhanced convenience and accessibility for patients.

Pipeline and Clinical Programs

The company's diverse pipeline includes several promising candidates targeting a range of infectious diseases, including norovirus, coronavirus (including SARS-CoV-2), and influenza. Vaxart's lead programs have demonstrated encouraging results in clinical trials, underscoring the potential of its oral vaccine platform.

Financials

In the third quarter of 2024, Vaxart reported revenue of $4.93 million, a significant increase from the $2.1 million recorded in the same period of 2023. This revenue growth of 134.3% was primarily driven by government contracts related to the Biomedical Advanced Research and Development Authority (BARDA), a testament to the industry's confidence in Vaxart's capabilities. The revenue consisted of $4.89 million from government contracts and $40,000 in non-cash royalty revenue related to the sale of future royalties.

For the most recent fiscal year ending December 31, 2023, Vaxart reported total revenue of $7.38 million. The company's net loss for the same period was $82.47 million. Operating cash flow (OCF) for the fiscal year 2023 was negative $70.45 million, while free cash flow (FCF) was negative $72.32 million.

In the third quarter of 2024, Vaxart's net loss was $14.08 million, with research and development expenses of $15.07 million and general and administrative expenses of $4.34 million. The company's OCF for Q3 2024 was negative $4.20 million, and FCF was negative $4.21 million.

Liquidity

Vaxart's financial position remains robust, with $58.7 million in cash, cash equivalents, and investments as of September 30, 2024. The company's management expects this cash runway to sustain operations into 2026, providing ample resources to advance its pipeline and achieve key milestones.

As of December 31, 2023, Vaxart reported $34.76 million in cash and cash equivalents, along with $4.96 million in short-term investments, totaling $39.71 million in liquid assets. The company's debt-to-equity ratio stood at 0.2659, indicating a relatively low level of leverage. Vaxart's current ratio and quick ratio were both 3.32, suggesting strong short-term liquidity.

COVID-19 Program

In the COVID-19 program, Vaxart's ongoing Phase 2b clinical trial is a testament to the company's commitment to addressing the global health crisis. The study, funded by a BARDA contract valued at up to $456 million, is designed to evaluate the relative efficacy, safety, and immunogenicity of Vaxart's oral COVID-19 vaccine candidate compared to an approved mRNA vaccine. The trial's sentinel cohort of 400 participants has been fully enrolled, and the company expects to initiate the second, larger phase of the study in early 2025 upon a favorable review by the independent Data and Safety Monitoring Board (DSMB) and the FDA.

Norovirus Program

Vaxart's norovirus program has also gained significant traction, with the company presenting promising data at the Infectious Disease Week (IDWeek) conference. The Phase 2 study evaluating the safety, immunogenicity, and clinical efficacy of Vaxart's norovirus vaccine candidate met several primary endpoints, including a statistically significant reduction in the rate of norovirus infection. In September 2023, Vaxart announced that its Phase 2 GI.1 norovirus challenge study met five of six primary endpoints based on preliminary topline data. The study showed a statistically significant 29% relative reduction in the rate of norovirus infection between the vaccinated and placebo arms, as well as a strong induction of norovirus-specific antibodies.

Additionally, in July 2023, the company announced that its Phase 2 dose-ranging trial evaluating the safety and immunogenicity of the bivalent norovirus vaccine candidate met all primary endpoints, with the vaccine candidate showing a favorable safety profile and robust immunogenicity. The company's Phase 1 study in lactating mothers and their nursing infants demonstrated the potential for antibody transfer through breast milk, highlighting the versatility of Vaxart's platform.
