Vir Biotechnology, Inc. Presents Complete Week 96 Data from Phase 2 Solstice Clinical Trial in Hepatitis Delta Vir Biotechnology, Inc. announced the Company will present data from the Phase 2 SOLSTICE trial evaluating the combination of tobevibart and elebsiran for chronic hepatitis delta at the upcoming EASL Congress 2026 in Barcelona, Spain, May 27-30, 2026.
CHD is the most severe form of chronic viral hepatitis and was recently classified as carcinogenic by the International Agency for Research on Cancer. People living with the disease rapidly progress to cirrhosis, liver failure and liver-related death. Because ongoing hepatitis delta virus (HDV) replication drives disease progression, achieving undetectable virus, as defined by HDV RNA TND (target not detected), is considered an important virologic marker associated with improved clinical outcomes in CHD. Individuals with CHD who have detectable HDV RNA are at a higher risk of experiencing any liver-related event, including developing compensated and decompensated cirrhosis, hepatocellular carcinoma, liver transplantation and mortality, compared to patients with undetectable HDV RNA. There are currently no approved treatments in the U.S., and options are limited in the European Union and globally. Tobevibart and elebsiran are investigational agents being evaluated as a novel combination regimen administered monthly as two separate sequential subcutaneous injections for the treatment of CHD. The combination is designed to disrupt the HDV life cycle at multiple points by addressing both viral entry and the sustained presence of hepatitis B surface antigen (HBsAg) that enables ongoing HDV replication. Tobevibart is an investigational broadly neutralizing monoclonal antibody (mAb) targeting HBsAg. 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 was identified using Vir Biotechnology’s proprietary mAb discovery platform. The Fc domain has been engineered to increase immune engagement and clearance of HBsAg immune complexes and incorporates Xencor’s Xtend™ technology to extend half-life. Elebsiran is an investigational hepatitis B virus-targeting small interfering ribonucleic acid (siRNA) licensed from Alnylam Pharmaceuticals, Inc. It is designed to degrade hepatitis B virus RNA transcripts and limit the production of HBsAg. Announcement • Apr 17

Vir Biotechnology, Inc. Enrolls First Patient in Phase 3 Eclipse Registrational Program for Chronic Hepatitis Delta Vir Biotechnology, Inc. announced the enrollment of the first patient in its Phase 3 ECLIPSE registrational program. The ECLIPSE registrational program is designed to evaluate the efficacy and safety of tobevibart in combination with elebsiran in people living with chronic hepatitis delta (CHD). ECLIPSE 1, the first trial of the program to be initiated, and ECLIPSE 2 are Phase 3 trials designed to provide the registrational data needed for submission to multiple regulatory agencies. ECLIPSE 3, a Phase 2b trial, is designed to provide important supportive data to help enable access and reimbursement strategies in key European markets. CHD is a debilitating inflammatory liver disease caused by the hepatitis delta virus (HDV). It is the most severe form of chronic viral hepatitis2 and on average, people living with CHD will progress to cirrhosis and liver failure within 5 years.3 There is a high unmet medical need for effective treatments, as there are no approved therapies in the U.S., and options are limited in the European Union and globally. The objective of therapy is to eliminate the virus. Tobevibart in combination with elebsiran offers the potential to achieve this by tackling the viral lifecycle through multiple mechanisms. The significant unmet need in CHD and the potential for tobevibart and elebsiran to provide a much-needed treatment option has been recognized by the U.S. Food and Drug Administration (FDA) with Breakthrough and Fast Track designations, and by the European Medicines Agency (EMA) Priority Medicines (PRIME) and orphan drug designation. ECLIPSE is a Phase 3 registrational program to evaluate the safety and efficacy of tobevibart in combination with elebsiran in patients with chronic hepatitis delta. ECLIPSE includes three randomized, controlled trials designed to evaluate the combination therapy in comparison to deferred treatment or bulevirtide. ECLIPSE 1, the first trial of the program to be initiated, is a Phase 3 trial that will assess the efficacy and safety of tobevibart and elebsiran compared to deferred treatment in regions such as the U.S. where bulevirtide is not available or other regions where its access is limited. ECLIPSE 2 is a Phase 3 trial that will evaluate the efficacy and safety of switching to tobevibart and elebsiran in people with CHD who have not achieved viral suppression with bulevirtide therapy. ECLIPSE 1 and 2 are designed to provide the registrational efficacy and safety data needed for potential submission to global regulatory agencies. ECLIPSE 3 is a Phase 2b head-to-head trial to evaluate tobevibart and elebsiran compared with bulevirtide in bulevirtide-naïve patients, and it is designed to provide important supportive data to help establish access and reimbursement in key markets. ECLIPSE 1 plans to enroll 120 participants in the U.S. or other regions where bulevirtide use is limited. Participants will be randomized 2:1 to receive either tobevibart in combination with elebsiran or deferred treatment. During the deferred treatment period, participants will receive only nucleoside reverse transcriptase inhibitors (NRTIs). After the initial delay period, participants will be switched to the combination therapy of tobevibart and elebsiran. The composite primary endpoint measures HDV RNA at the lower limit of quantification target not detected or HDV RNA TND (defined as HDV RNA < 0 IU/mL) and ALT normalization at Week 48, compared to the deferred treatment group at the end of their deferred treatment period. Tobevibart is an investigational broadly neutralizing monoclonal antibody targeting the hepatitis B surface antigen (HBsAg). 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 was identified using Vir Biotechnology’s proprietary monoclonal antibody discovery platform. The Fc domain has been engineered to increase immune engagement and clearance of HBsAg immune complexes and incorporates Xencor’s Xtend™ technology to extend half-life. Tobevibart is administered subcutaneously, and it is currently in clinical development for the treatment of patients with chronic hepatitis delta and patients with chronic hepatitis B. Elebsiran is an investigational hepatitis B virus-targeting small interfering ribonucleic acid (siRNA) discovered by Alnylam Pharmaceuticals, Inc. It is 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 the treatment of patients with chronic hepatitis delta and patients with chronic hepatitis B.

Vir Biotechnology Announces Encouraging Safety and Efficacy Data in Ongoing Dose Escalation Trials for Dual Masked T-Cell Engagers VIR-5818 in Solid Tumors and VIR-5500 in mCRPC Vir Biotechnology, Inc. is presenting initial Phase 1 data from two of its dual-masked T-cell engagers (TCEs): VIR-5818, targeting a variety of HER2-expressing solid tumors; and VIR-5500, targeting PSMA in metastatic castration-resistant prostate cancer (mCRPC). Data show encouraging preliminary safety and efficacy profiles with no dose-limiting cytokine release syndrome (CRS), maximum tolerated dose (MTD) not yet reached as dose escalation continues, and early clinical response signals observed in heavily pretreated participants. These initial results provide clinical support for Vir Biotechnology’s in-licensed PRO-XTEN™ masking technology, which is designed to enable the selective activation of TCEs in the tumor microenvironment, mitigating damage to healthy cells and reducing toxicity. Despite availability of HER2-targeting therapies, there remains a significant unmet need for treatments with novel mechanisms of action to improve tolerability and extend survival. Currently, no HER2-directed immunotherapies are approved for solid tumors. The preliminary safety and efficacy data of VIR-5818 support the tumor-specific activation of PRO-XTENTM dual-masked TCEs and the potential of this technology to broaden the therapeutic index of TCEs. VIR-5818 is being evaluated in a Phase 1 clinical trial (NCT05356741) designed to study its safety and pharmacokinetics alone, and in combination with pembrolizumab, in participants with a variety of HER2-expressing cancers, including breast and colorectal cancer (CRC). The study has enrolled 79 heterogeneous and heavily pretreated participants in monotherapy cohorts. Early efficacy data indicate that 50% (10/20) of participants receiving VIR-5818 doses =400 µg/kg experienced dose-dependent tumor shrinkage across multiple HER2-positive tumor types. This includes participants who had received up to 9 prior lines of therapy. Strong anti-tumor activity was observed in a subset of participants with HER2-positive CRC who have exhausted standard of care. In this subset, confirmed partial responses (cPRs) were seen in 33% (2/6) of participants at early doses, and one patient continued in cPR for more than 18 months as of the data cut-off. Preliminary safety data demonstrate that VIR-5818 is generally well-tolerated, with minimal grade 1 or 2 CRS (20% and 10%, respectively) and no grade 3 or greater CRS observed in any of the 79 participants across doses up to 1000 µg/kg. Most treatment-emergent adverse events (TEAEs) were low grade, reversible and manageable. The MTD has not yet been reached. Preliminary pharmacokinetics and safety data indicate low systemic unmasking of the TCE, suggesting tumor-specific activation. Dual masking results in a half-life of approximately 6 days, which may enable a less frequent dosing regimen. As a result, Vir Biotechnology is currently evaluating a Q3W dosing regimen. Prostate cancer is the second most diagnosed cancer in men1. Despite advancements, there is still a significant unmet need for efficacious, well-tolerated treatments that can extend survival and improve quality of life. VIR-5500 is being evaluated in a Phase 1 clinical trial (NCT05997615) designed to assess its safety, pharmacokinetics, and preliminary efficacy in participants with mCRPC. The study has enrolled 18 participants with significant disease burden who have received 3 to 6 prior lines of therapy. Early efficacy data show encouraging signs of prostate-specific antigen (PSA) responses, and PSA reductions were observed in 100% (12/12) of participants after an initial dose =120 µg/kg. PSA50 response was confirmed in 58% (7/12) of participants receiving a first dose =120 µg/kg. Preliminary data show a promising safety profile, with no dose-limiting toxicities observed up to 1000 µg/kg without prophylactic corticosteroids. Safety findings showed minimal grade 1 or 2 CRS (17% and 11%, respectively) and no grade 3 or greater CRS at any dose. Most TEAEs were low grade. No hearing loss has been reported, suggesting safety benefits of dual masking in preventing on-target, off-tumor toxicities. Dose escalation is ongoing, and the MTD for VIR-5500 has not yet been reached. Preliminary pharmacokinetics and safety data indicate tumor-specific activation with minimal unmasking outside the tumor. The dual-masked TCE shows a desirable half-life of 8-10 days, which is enabling Vir Biotechnology to evaluate a Q3W dosing regimen. The safety and tolerability profile observed for VIR-5500 in ongoing dose escalation, together with the observed signs of early anti-tumor activity at low doses, may enable a wide therapeutic index.

Vir Biotechnology, Inc. Presents Positive Chronic Hepatitis Delta Clinical Trial Data and Announces Initiation of Phase 3 Registrational Program Vir Biotechnology, Inc. announced positive results from the SOLSTICE Phase 2 clinical trial evaluating tobevibart alone, or in combination with elebsiran, in people with chronic hepatitis delta (CHD). The most-advanced and potential first-of-its-kind investigational human monoclonal antibody and siRNA combination dosed monthly achieved 100% virologic response and rapid hepatitis delta virus (HDV) RNA suppression. HDV RNA below the lower limit of quantification (These data were presented in an oral session at the American Association for the Study of Liver Diseases (AASLD) The Liver Meeting, in San Diego, CA. Based on these results, and following a recent meeting with the FDA, Vir Biotechnology plans to initiate the Phase 3 registrational ECLIPSE program in the first half of 2025 to further evaluate the combination of tobevibart and elebsiran for the treatment of CHD. CHD is a chronic inflammatory liver disease caused by HDV. It is the most severe form of chronic viral hepatitis and on average, people living with CHD will progress to cirrhosis and liver failure within 5 years. There is no approved treatment in the United States. The objective of therapy is to clear the virus, and combination therapy offers the potential to do so by tackling the viral lifecycle through multiple mechanisms. Primary Endpoint Analysis from the Phase 2 SOLSTICE TrialClinical trial participants were randomized to receive tobevibart 300 mg monotherapy every two weeks (n=33) or a combination of tobevibart 300 mg and elebsiran 200 mg every four weeks (combination de novo arm, n=32). In addition, the participants from previous tobevibart or elebsiran monotherapy cohorts could rollover to receive the combination of tobevibart 300 mg and elebsiran 200 mg every four weeks (combination rollover, n=13). Rates of virologic suppression were evaluated at Week 24, and further assessed at Weeks 36, 48 and 60 in those participants that had reached each timepoint. Further monitoring will continue up to 192 weeks. Rapid and Sustained Virologic Suppression – 100% of participants across combination arms achieved an HDV RNA =2 log10 decrease or below limit of detection (LOD) at Week 24, and this rate was sustained over time in all participants at Weeks 36 (22/22) and those in the rollover cohort that reached Week 60 (5/5). HDV RNA TND was achieved in 41% (13/32) of participants across combination arms at Week 24 and this rose to 64% (14/22) at Week 36. By week 60, this had risen further with 80% (4/5) of participants in the rollover cohort having achieved no detectable viral RNA. Approximately 90% of participants receiving the combination achieved reductions in hepatitis B surface antigen (HBsAg) values below <10 IU/mL at Week 24, with sustained responses at later time points. This indicates suppression of the key biologic mechanisms that HDV requires for viral replication. ALT Normalization – Alanine aminotransferase (ALT) decreased in most participants between Day 1 and Week 24 and normalized in 47% (15/32) of participants in the combination de novo cohort and 56% (5/9) in the rollover cohort by Week 24. These rates were sustained at Week 36. Combined Endpoints – The protocol defined combined endpoint of HDV RNA decrease = 2 log10 compared to baseline or HDV RNA below LOD and ALT normalization at Week 24 was observed in 47% (15/32) of participants in the combination de novo arm. The more stringent composite endpoint of HDV RNA TND and ALT normalization was achieved in 19% (6/32) of participants in the combination de novo arm at Week 24, which increased to 27% (6/22) by Week 36. This trend was reflected in the combination rollover cohort in which 33% (3/9) of participants achieved this endpoint at Week 24 and 40% (2/5) at Week 60. Rates of HDV RNA suppression and ALT normalization were similar between non-cirrhotic and cirrhotic participants across combination arms. Safety Profile – The safety profile of tobevibart and elebsiran is consistent with previous studies. Treatment-emergent adverse events (TEAEs) were generally mild or moderate and transient across all treatment groups, with influenza-like illness being the most common event. No ALT flares were observed. There were no study-related discontinuations in the combination arms, and no treatment-related severe adverse events (SAEs) were reported. Phase 3 Registrational ECLIPSE ProgramFollowing a meeting with the FDA, Vir Biotechnology finalized the design of the Phase 3 registrational clinical program, ECLIPSE, which evaluates the tobevibart and elebsiran combination in people living with CHD. This program, which will commence in the first half of 2025, will include three randomized, controlled trials designed to evaluate the combination therapy in comparison to deferred treatment or bulevirtide. All studies will enroll both cirrhotic and non-cirrhotic participants. ECLIPSE 1 and 2 are Phase 3 trials designed to provide the registrational efficacy and safety data needed for submission to global regulatory agencies. ECLIPSE 3 is a Phase 2b trial designed to provide important supportive data, particularly in Europe, to help establish appropriate pricing and reimbursement in key markets. ECLIPSE 1 will assess the efficacy and safety of tobevibart and elebsiran compared to deferred treatment in regions such as the U.S. where bulevirtide is not available or its use is limited. ECLIPSE 2 will evaluate the efficacy and safety of switching to tobevibart and elebsiran in people with CHD who have not achieved viral suppression with bulevirtide therapy. ECLIPSE 3 is a Phase 2b head-to-head trial to evaluate tobevibart and elebsiran compared with bulevirtide in bulevirtide-naïve patients. Announcement • Nov 15
Vir Biotechnology, Inc. Announces Positive End-Of-T Treatment Results for Tobevibart and Elebsiran Combinations in Chronic Hepatitis B from the March Study at AASLD The Liver Meeting Vir Biotechnology, Inc. announced end-of-treatment data from Part B of the MARCH Phase 2 clinical study evaluating combinations of tobevibart and elebsiran, with or without pegylated interferon alfa (PEG-IFNa), in participants with chronic hepatitis B. The study demonstrated promising rates of hepatitis B surface antigen (HBsAg) loss (seroclearance) in participants with low baseline HBsAg (<1000 IU/mL) in both combination regimens. The efficacy and safety profile support continued development to evaluate the potential to achieve a functional cure. Chronic hepatitis B (CHB) is a long-lasting, inflammatory liver disease caused by the hepatitis B virus (HBV). The World Health Organization estimates that 254 million people live with CHB, and an estimated 1.1 million yearly deaths are associated with the disease. Complications from CHB may include liver cirrhosis, liver failure and liver cancer. Although CHB can be treated, there is no cure. Participants in the trial received tobevibart and elebsiran alone (doublet regimen) or in combination with PEG-IFNa (triplet regimen). This analysis includes data from 51 participants in the doublet regimen arm and 27 participants in the triplet regimen arm at the end of treatment. Tobevibart was administered at 300 mg every 4 weeks; elebsiran, at 200 mg every 4 weeks; and PEG-IFNa at 180 µg weekly. Study primary endpoints include HBsAg seroclearance (defined as HBsAg below the lower limit of quantification) and treatment-emergent adverse events (TEAEs) at end of treatment. Secondary endpoints include anti-HBs seroconversion (defined as development of anti-HBs=10 mIU/mL) at end of treatment. The doublet and triplet regimens resulted in HBsAg loss at the end of treatment in 39% (7/18) and 46% (5/11) of participants with baseline HBsAg<1,000 IU/mL, respectively. The proportion of participants with varying baseline HBsAg levels who achieved HBsAg loss at end of treatment was 16% (8/51) for the doublet and 22% (6/27) for the triplet regimen. The doublet regimen resulted in 50% (4/8) of participants who had achieved HBsAg loss also achieving anti-HBs seroconversion. All participants with HBsAg loss at the end of treatment who received the triplet regimen achieved anti-HBs seroconversion (100%, 6/6). Participants with HBsAg seroclearance at end of treatment who meet eligibility criteria will discontinue treatment. Functional cure assessment will occur 24 weeks after treatment discontinuation. The safety and tolerability profile of tobevibart and elebsiran was consistent with prior studies, with no new safety concerns identified. TEAEs were generally mild or moderate. Announcement • Oct 18

Vir Biotechnology, Inc. Receives FDA IND Clearance and Fast Track Designation for Tobevibart and Elebsiran for the Treatment of Chronic Hepatitis Delta Infection Vir Biotechnology, Inc. announced that the U.S. Food and Drug Administration (FDA) has cleared its investigational new drug (IND) application and granted Fast Track designation for the combination of tobevibart and elebsiran for the treatment of chronic hepatitis delta infection. Tobevibart, an investigational monoclonal antibody, and elebsiran, an investigational small interfering ribonucleic acid, are currently being evaluated in the Company’s Phase 2 SOLSTICE hepatitis delta clinical trial, with complete 24-week treatment data on track to be reported in the fourth quarter. The FDA’s Fast Track designation is intended to facilitate the development and expedite the review of drugs to treat serious conditions and fill an unmet medical need. The World Health Organization considers hepatitis delta to be the most severe form of chronic viral hepatitis due to more rapid progression towards liver cancer and liver-related death. It is estimated that at least 12 million people are living with chronic hepatitis delta globally. In June, the Company announced preliminary Phase 2 SOLSTICE trial data which suggests treatment with tobevibart alone or in combination with elebsiran was generally well tolerated and participants achieved high rates of virologic response at weeks 12 and 24, durable virologic response through 48 weeks, and high rates of ALT normalization. The complete 24-week treatment data is expected in the fourth quarter. The Company is working to expedite the initiation of its next study, the ECLIPSE trial. The open-label, randomized, controlled ECLIPSE trial is designed to support potential registration and will evaluate the safety and efficacy of a monthly-administered subcutaneous injection of tobevibart and elebsiran using the current standard of care therapy as a comparator. About the Phase 2 SOLSTICE Trial: The SOLSTICE trial (NCT05461170) is evaluating the safety, tolerability and efficacy of tobevibart and elebsiran for the treatment of people living with chronic hepatitis delta. One cohort is evaluating the combination of tobevibart and elebsiran dosed every 4 weeks with a second cohort evaluating tobevibart monotherapy every 2 weeks. Approximately 50% of participants have compensated cirrhosis. Tobevibart is an investigational subcutaneously administered antibody designed to inhibit entry of hepatitis B and hepatitis delta viruses into hepatocytes, neutralize both hepatitis B virus and hepatitis delta virus virions, and to reduce the level of virions 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. Elebsiran is an investigational subcutaneously administered 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. Vir believes it has the potential to have direct antiviral activity against hepatitis B virus and hepatitis delta virus. It is the first siRNA in the clinic to include Enhanced Stabilization Chemistry Plus (ESC+) technology to enhance stability and minimize off-target activity, which potentially could result in an increased therapeutic index. Elebsiran is the first asset in the Company’s collaboration with Alnylam Pharmaceuticals, Inc. to enter clinical trials. Announcement • Jun 06

Vir Biotechnology, Inc. Announces Multiple Abstracts Highlighting New Chronic Hepatitis B and Hepatitis Delta Data Accepted for Presentation at AASLD’s the Liver Meeting® 2023 Vir Biotechnology, Inc. announced that eight abstracts highlighting new data from its chronic hepatitis B (CHB) and chronic hepatitis delta (CHD) clinical programs have been accepted for presentation at the American Association for the Study of Liver Diseases (AASLD) The Liver Meeting®, taking place in Boston, MA, from November 10-14, 2023. These include seven poster presentations, one of which is a late-breaking poster, and one late-breaking oral presentation. Chronic hepatitis B (CHB) infection remains an urgent global public health challenge associated with significant morbidity and mortality. Approximately 300 million people around the world are living with CHB, and approximately 900,000 of them die from associated complications each year. These patients are significantly underserved by existing therapies with low functional cure rates, lifelong daily therapy and/or poor tolerability. Vir is working to achieve a functional cure for the millions of people with CHB around the world through its broad and differentiated portfolio. Chronic hepatitis delta (CHD) infection occurs as a simultaneous co-infection or super-infection with chronic hepatitis B. An estimated 12 million people globally are infected with CHD, representing approximately 5% of those infected with CHB. CHB-CHD co-infection is considered the most severe form of chronic viral hepatitis due to more rapid progression toward hepatocellular carcinoma and liver-related death. VIR-2218 (BRII-835) is an investigational subcutaneously administered hepatitis B virus-targeting small interfering ribonucleic acid (siRNA) that Vir believes has the potential to stimulate an immune response and have direct antiviral activity against hepatitis B virus and hepatitis delta virus. It is the first siRNA in the clinic to include Enhanced Stabilization Chemistry Plus (ESC+) technology to enhance stability and minimize off-target activity, which potentially could result in an increased therapeutic index. VIR-2218 is the first asset in the Company’s collaboration with Alnylam Pharmaceuticals, Inc. to enter clinical trials. VIR-3434 (BRII-877) is an investigational subcutaneously administered antibody designed to block entry of hepatitis B and hepatitis delta viruses into hepatocytes and to reduce the level of virions and subviral particles in the blood. VIR-3434, which incorporates Xencor’s Xtend™ and other Fc technologies, has been engineered to potentially function as a T cell vaccine against hepatitis B virus and hepatitis delta virus, as well as to have an extended half-life.

Biomedical Advanced Research and Development Authority Awards Funding to Vir Biotechnology, Inc. to Support Development of Antibody Platform Technologies for Global Infectious Disease Threats Vir Biotechnology, Inc. announced that the Biomedical Advanced Research and Development Authority (BARDA), part of the U.S. Department of Health and Human Services’ (HHS) Administration for Strategic Preparedness and Response (ASPR), has awarded Vir approximately $50 million in new funding to advance the development of novel monoclonal antibody (mAb) candidates and delivery solutions to widen the applicability of mAbs in COVID-19 and in pandemic preparedness and response. The new funding will support research and development of novel alternative mAb delivery technologies that have the potential to revolutionize mAb delivery by increasing expression relative to existing technologies. Such delivery could widen the breadth of administration options and shorten development and manufacturing timelines. $40 million of the total funds is part of ‘Project NextGen,’ an initiative by the HHS to advance a pipeline of new, innovative vaccines and therapeutics for COVID-19 and will support the development of VIR-7229 through Phase 1 in the context of developing alternative mAb delivery technologies. The Phase 1 trial is expected to be completed in the second half of 2025. $10 million of the total funds falls under support from the Division of Chemical, Biological, Radiological and Nuclear (CBRN) medical countermeasures of BARDA which will support the discovery of new mAbs against a second pathogen of pandemic potential in the context of further advancing alternative mAb delivery technologies. The new investment falls under Vir’s existing Other Transaction Authority (OTA), a multi-year contract BARDA awarded Vir in 2022. This OTA allows for a potential total investment of up to $1 billion to support Vir’s development of future pandemic influenza mAbs as well as the potential development of up to 10 emerging infectious disease or CBRN medical countermeasure candidates. The balance of the potential funding is subject to BARDA exercising up to 12 options in further support of the development of pre-exposure prophylactic antibodies for the prevention of influenza illness or supporting medical countermeasures for other pathogens of pandemic potential. Vir is also receiving approximately $11 million in additional BARDA funding that will be applied to wind down activities for the BARDA-supported Phase 2 PENINSULA trial evaluating the investigational prophylactic mAb VIR-2482 for the prevention of symptomatic influenza A illness. These programs have been funded in whole or in part with federal funds from the Department of Health and Human Services; Administration for Strategic Preparedness and Response (ASPR); Biomedical Advanced Research and Development Authority (BARDA), under OT number: 75A50122C00081.
