Pipeline Programs

Chronic Hepatitis Delta (CHD)

• Preliminary data from the Phase 2 chronic hepatitis delta SOLSTICE study was presented at the European Study of the Liver (EASL) Meeting in June 2024. This data demonstrated the potential for transformative treatment for people living with chronic hepatitis delta, with both tobevibart as a monotherapy, and in combination with elebsiran, achieving high rates of virologic response and ALT normalization after 12 and 24 weeks of treatment. No treatment-related serious adverse events were observed.
• The combination of tobevibart and elebsiran has been granted Fast Track Designation by the U.S. FDA. Given the robust rates of virologic suppression observed with the combination, the Company is diligently working to advance this regimen into a pivotal development program as quickly as possible to address the urgent needs of these patients.
• At the upcoming American Association for the Study of Liver Diseases (AASLD) "The Liver Meeting" in November 2024, the Company will present additional data from the Phase 2 chronic hepatitis delta SOLSTICE trial, including: 24-week clinical data for both study cohorts in approximately 60 patients and further data for those patients who were on study beyond 24 weeks at the time of data cut-off.
  • One cohort assesses the combination of tobevibart and elebsiran administered every four weeks, while a second cohort evaluates tobevibart monotherapy administered every two weeks.
• The SOLSTICE trial is evaluating the safety, tolerability and efficacy of tobevibart and elebsiran for the treatment of chronic hepatitis delta.

Chronic Hepatitis B (CHB)

• The Company plans to share end-of-treatment data from the Phase 2 MARCH Part B trial as a Late Breaking presentation at the AASLD meeting in November 2024.
  • The MARCH-B trial is evaluating the safety, tolerability and antiviral activity of the triplet combination of tobevibart and elebsiran plus peginterferon alfa-2a in approximately 30 participants, and approximately 50 participants treated with the doublet combination of tobevibart and elebsiran.
  • The Company plans to share further data assessing a potential functional cure in the second quarter of 2025.

Solid Tumors

• VIR-5818 is a dual-masked HER2-targeted T-cell engager in clinical development designed to minimize off-tumor toxicity, potentially allowing for higher doses and increased efficacy to address the significant unmet needs of patients with HER2 expressing cancers.
  • A Phase 1 basket study of VIR-5818 as a monotherapy, and in combination with pembrolizumab, is on-going in multiple tumor types, including metastatic breast cancer and metastatic colorectal cancer.
  • The Company plans to share initial clinical data for VIR-5818 in the first quarter of 2025.
• VIR-5500 is a dual-masked PSMA directed T-cell engager in clinical development designed to minimize off-tumor toxicity and potentially improve efficacy relative to the existing approved PSMA-targeted therapies.
  • A Phase 1 dose escalation study of VIR-5500 is ongoing to assess its safety profile and optimal dose levels for future development in metastatic-castration resistant prostate cancer.
  • The Company plans to share initial clinical data for VIR-5500 in the first quarter of 2025.
• VIR-5525 is a dual-masked EGFR targeted T-cell engager with a cleared Investigational New Drug Application (IND) from the U.S. FDA.
  • The Company plans to initiate a Phase 1 basket study of VIR-5525 in the first quarter of 2025 in patients across a number of solid tumor indications of high unmet need, which may include metastatic head and neck squamous cell carcinoma, metastatic adenocarcinoma, squamous non-small cell lung cancer, and metastatic colorectal cancer.

Preclinical Pipeline Candidates

• The Company continues to advance pre-clinical assets in respiratory syncytial virus in partnership with GSK and pursue HIV cure in collaboration with the Bill & Melinda Gates Foundation.

Corporate Update

• On August 1, 2024 the Company announced an exclusive worldwide license to three clinical-stage masked T-cell engagers (TCEs) with potential applications in a range of cancers, as well as the exclusive use of the proprietary PRO-XTEN™ masking platform for oncology and infectious disease. The Company announced closing of the agreement with Sanofi on September 9, 2024.
  • Key employees from Sanofi, possessing extensive scientific and development expertise in TCEs, and in-depth experience with the PRO-XTEN™ platform, joined the Company following the closing of the agreement.
• On August 1, 2024 the Company announced the phase-out of clinical programs in influenza, COVID-19, and its T-cell based viral vector platform. The Company is seeking partners to advance these clinical programs through further development. Additionally, the Company announced a workforce reduction of approximately 25%, or approximately 140 employees, and expects to end 2024 with approximately 435 employees – a decrease of approximately 200 from its peak headcount in the second quarter of 2023.
• On September 10, 2024, the Company announced the appointment of Jason O'Byrne as Executive Vice President and Chief Financial Officer, effective October 2, 2024. Mr. O'Byrne is an accomplished executive with more than 20 years of finance and operations experience, and brings leadership in capital allocation and formation, corporate strategy and operational excellence.
• The Company will host two virtual investor events instead of the previously scheduled R&D Day in the fourth quarter of 2024. The first event, focusing on our hepatitis programs, will be held in November 2024, following the AASLD conference, and will provide detailed updates on our hepatitis delta and hepatitis B programs. In the first quarter of 2025, the Company will share initial clinical data for our masked T-cell engager programs during a second dedicated investor event.

Third Quarter 2024 Financial Results

Cash, Cash Equivalents and Investments: As of September 30, 2024, the Company had approximately $1.19 billion in cash, cash equivalents and investments, representing a decrease of approximately $245.1 million during the third quarter of 2024. The decrease includes a $103.7 million upfront payment made to Sanofi upon the closing of the agreement and a $75.0 million escrowed milestone payment reclassified to restricted cash. The escrowed milestone is subject to VIR-5525 achieving "first in human dosing" by 2026. Excluding the impact of the Sanofi agreement, the decrease in cash, cash equivalents and investments in the third quarter was approximately $66.4 million.

Revenues: Total revenues for the quarter ended September 30, 2024, were $2.4 million compared to $2.6 million for the same period in 2023.

Cost of Revenue: Cost of revenue was nominal for the third quarter of 2024 and 2023.

Research and Development Expenses (R&D): R&D expenses for the third quarter of 2024 were $195.2 million, which included $8.9 million of non-cash stock-based compensation expense, compared to $145.0 million for the same period in 2023, which included $15.8 million of non-cash stock-based compensation expense. The increase was primarily driven by $102.8 million of the Sanofi upfront payment being recognized as in-process research and development expense, partially offset by lower clinical development costs and manufacturing costs associated with the discontinued flu asset, VIR-2482.

Selling, General and Administrative Expenses (SG&A): SG&A expenses for the third quarter of 2024 were $25.7 million, which included $7.8 million of non-cash stock-based compensation expense, compared to $40.9 million for the same period in 2023, which included $11.1 million of non-cash stock-based compensation expense. The decrease was largely related to cost savings initiatives implemented during the second half of 2023.

Restructuring, long-lived assets impairment and related charges: Restructuring, long-lived assets impairment and related charges for the third quarter of 2024 were $12.7 million compared to $3.4 million for the same period in 2023. The increase was primarily driven by severance charges incurred related to our strategic restructuring announcement in August 2024 and to a lesser extent right-of-use asset impairment charges related to the closing of our Portland, Oregon facility, which was previously announced on December 13, 2023.

Other Income: Other income for the third quarter of 2024 was $17.8 million compared to $20.1 million for the same period in 2023. The decrease was primarily due to lower interest income.

(Provision for) Benefit from Income Taxes: Provision for income taxes for the third quarter of 2024 was $0.2 million compared to a benefit from income taxes of $3.2 million for the same period in 2023.

Net Loss: Net loss attributable to Vir for the third quarter of 2024 was $(213.7) million, or $(1.56) per share, basic and diluted, compared to a net loss of $(163.4) million, or $(1.22) per share, basic and diluted for the same period in 2023.

2024 Financial Guidance

The Company has updated its operating expense guidance for the full-year 2024, which includes the upfront in-process research and development expense associated with the clinical-stage T-cell engagers licensed through its agreement with Sanofi:

The GAAP operating expense guidance does not include the effect of GAAP adjustments caused by events that may occur subsequent to the publication of this guidance, including, but not limited to, business development activities, litigation, in-process R&D impairments, and changes in the fair value of contingent considerations.

About Tobevibart (VIR-3434)

Tobevibart is an investigational broadly neutralizing monoclonal antibody targeting the hepatitis B surface antigen. It is designed to inhibit the entry of hepatitis B and hepatitis delta viruses into hepatocytes, and to reduce the level of circulating viral and subviral particles in the blood. Tobevibart, which incorporates Xencor's Xtend™ and other Fc technologies, has been engineered to have an extended half-life and was identified using Vir's proprietary monoclonal antibody discovery platform. Tobevibart is administered subcutaneously, and it is currently in clinical development for treatment of patients with chronic hepatitis B and patients with chronic hepatitis delta.

About Elebsiran (VIR-2218)

Elebsiran is an investigational hepatitis B virus-targeting small interfering ribonucleic acid (siRNA) designed to degrade hepatitis B virus RNA transcripts and limit the production of hepatitis B surface antigen. Current data indicates that it has the potential to have direct antiviral activity against hepatitis B virus and hepatitis delta virus. Elebsiran is administered subcutaneously, and it is currently in clinical development for treatment of patients with chronic hepatitis B and patients with chronic hepatitis delta. It is the first asset in Vir's collaboration with Alnylam Pharmaceuticals, Inc. to enter clinical studies.

About VIR-5818, VIR-5500, VIR-5525

VIR-5818, VIR-5500, VIR-5525 are investigational, clinical candidates currently being evaluated for the treatment of solid tumors. These assets leverage the PRO-XTEN™ masking technology with three different T-cell engagers (TCEs) targeting HER2, PSMA, and EGFR, respectively.

TCEs are powerful anti-tumor agents that direct the immune system, specifically T-cells, to destroy cancer cells. The PRO-XTEN™ masking technology is designed to keep the TCEs inactive (or masked) until they reach the tumor microenvironment, where tumor-specific proteases cleave off the mask and activate the TCEs leading to killing of cancer cells. By driving the activity exclusively to the tumor microenvironment, we aim to circumvent the traditionally high toxicity associated with TCEs and increase their efficacy and tolerability. Additionally, the mask also helps drug candidates stay in the bloodstream longer in their inactive form, allowing them to better reach the site of action and potentially allowing more convenient dosing regimens for patients and clinicians.
