Business Overview and History
Vir Biotechnology, Inc. is a clinical-stage biopharmaceutical company that is revolutionizing the treatment of serious infectious diseases and cancer by harnessing the power of the immune system. The company's diverse pipeline and innovative platform technologies have positioned it at the forefront of the industry, offering hope to patients in desperate need of effective therapies.
Vir Biotechnology was incorporated in April 2016 and commenced principal operations later that year. In its early years, the company focused primarily on organizing and staffing, business planning, raising capital, identifying, acquiring, developing, and in-licensing technology platforms and product candidates, as well as conducting preclinical studies and clinical trials.
The company has financed its operations primarily through sales of its common stock from its initial public offering, subsequent follow-on offerings, and payments received under its grant and collaboration agreements. As of December 31, 2022, Vir Biotechnology had $1.63 billion in cash, cash equivalents, and investments, demonstrating its strong financial position.
In June 2020, Vir Biotechnology entered into a significant collaboration agreement with GSK to research, develop, and commercialize products for the prevention, treatment, and prophylaxis of diseases caused by SARS-CoV-2 and potentially other coronaviruses. This collaboration initially focused on developing and commercializing antibodies targeting SARS-CoV-2, vaccines targeting SARS-CoV-2, and products based on genome-wide CRISPR screening of host targets.
A major milestone was achieved in May 2021 when the FDA granted an emergency use authorization (EUA) in the United States for sotrovimab, the first collaboration product under the Antibody Program with GSK. However, the landscape of COVID-19 treatment evolved rapidly, and in April 2022, the FDA excluded the use of sotrovimab in all U.S. regions due to the continued proportion of COVID-19 cases caused by certain variants.
In 2018, Vir Biotechnology entered into a collaboration, option, and license agreement with Brii Biosciences, granting them an exclusive option to obtain exclusive rights to develop and commercialize compounds and products arising from up to four of Vir Biotechnology's programs in the China Territory. To date, Brii Biosciences has exercised options for elebsiran and tobevibart, expanding Vir's reach in the Chinese market.
Throughout its history, Vir Biotechnology has faced various challenges, including the need to raise substantial additional funding to finance its operations as it has incurred net losses since inception. The company has also encountered obstacles in the development and commercialization of its product candidates, most notably the recent revocation of the EUA for sotrovimab by the FDA in December 2024.
One of Vir's key strengths is its proprietary antibody discovery and protein engineering platform, which has enabled the company to generate a diverse portfolio of product candidates targeting infectious diseases and oncology. The platform's AI-driven optimization capabilities have allowed Vir to develop highly potent and specific antibodies, setting the stage for potential breakthroughs in patient care.
In addition to its antibody platform, Vir has exclusively licensed the PRO-XTEN™ masking technology from Sanofi, which has been a game-changer in the company's oncology efforts. This innovative approach to T-cell engagers has the potential to unlock a wider therapeutic index, potentially improving both efficacy and safety for patients with solid tumors.
Vir's infectious disease pipeline is anchored by its work in chronic hepatitis delta (CHD) and chronic hepatitis B (CHB), where the company is pursuing unique combination therapy approaches that aim to address the significant unmet need in these areas. The company's CHD program, centered around the combination of tobevibart and elebsiran, has received both Breakthrough Therapy designation from the FDA and PRIME designation from the EMA, underscoring its potential to transform the treatment landscape.
Vir's oncology efforts have also gained significant traction, with the company's dual-masked T-cell engager (TCE) programs demonstrating promising early results. The VIR-5818 (HER2-targeted) and VIR-5500 (PSMA-targeted) TCEs have shown compelling efficacy signals and favorable safety profiles in heavily pretreated patients, validating the power of the PRO-XTEN platform.
