– Strategic clinical program for hepatitis B and D with potential for multiple value drivers in 2022 –
– Virtual R&D Day webcast scheduled for today, Wednesday, April 27, at 12:00 pm ET / 9:00 am PT –
SAN FRANCISCO, April 27, 2022 (GLOBE NEWSWIRE) -- Vir Biotechnology, Inc. (Nasdaq: VIR) today announced that the Company will review its robust hepatitis portfolio, including initial data from the first cohort of the MARCH (Monoclonal Antibody siRNA Combination against Hepatitis B) trial evaluating VIR-2218 in combination with VIR-3434, as well as a new program aimed at chronic hepatitis D. Details will be discussed today at 12:00 pm ET / 9:00 am PT during Vir’s virtual Hepatitis Portfolio R&D Day.
“We are pleased to share encouraging data from the MARCH trial, which suggest that VIR-2218 and VIR-3434 are additive in reducing hepatitis B surface antigen, with no drug-related safety signals reported to date – supporting our strategy of combining antivirals with immunomodulators,” said George Scangos, Ph.D., Vir’s chief executive officer. “We are also excited to announce a new synergistic program that will leverage our differentiated assets to treat hepatitis D, the most aggressive form of viral hepatitis for which there are limited treatment options. Together with the other ongoing combination trials in our pipeline, we believe we have multiple opportunities to achieve meaningful outcomes for both hepatitis B and D.”

Anticipated Hepatitis Milestones
In 2022, the Company expects to report data from multiple trials for the treatment of chronic hepatitis B virus (HBV) infection including:
- Additional data from the Phase 1 monotherapy trial of VIR-3434 and the Phase 2 monotherapy trial of VIR-2218 (first half of 2022).
- Additional data from the Phase 2 trial of VIR-2218 in combination with PEG-IFN-α (second half of 2022).
- Additional data from the first cohort (Part A) of the Phase 2 MARCH trial evaluating safety, pharmacokinetics and hepatitis B surface antigen (HBsAg) suppression (second half of 2022).
- Initial data from the Phase 2 trial evaluating VIR-2218 in combination with BRII-179, an investigational T cell vaccine, for the potential treatment of chronic HBV infection, led by Brii Biosciences (second half of 2022).
Beyond 2022, the Company expects to report:
- Initial data from the Phase 2 trial evaluating various combinations of VIR-2218, selgantolimod, Gilead’s investigational TLR-8 agonist, and nivolumab, an approved PD-1 inhibitor for HBV (first half of 2023).
- Initial data from the second cohort (Part B) of the Phase 2 MARCH trial for HBV to determine dose, length of treatment and evaluate triple cocktails, when VIR-3434 is given every four weeks (second half of 2023).
- Initial data from a Phase 2 viremic trial (STRIVE/THRIVE) of VIR-2218 in combination with VIR-3434 in the second half of 2023, following trial initiation in the second half of 2022.
- Initial data from a Phase 2 trial of VIR-2218 in combination with VIR-3434 for the treatment of HDV in 2023, following trial initiation in the second half of 2022.
Recent Publications
The Company recently sponsored a Nature Outlook Supplement titled “The Push to Eliminate a Viral Liver Disease.” This special edition, focused on chronic HBV, features independent news features and commentary pieces from leading academics focused on the latest advances in treatment, efforts to improve diagnosis and screening, and why equitable access to treatments and prevention methods will be central to eradicating HBV by 2030.
About Chronic Hepatitis B and D
Chronic hepatitis B virus (HBV) infection remains an urgent global public health challenge associated with significant morbidity and mortality. Approximately 300 million people around the world are living with HBV 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 poor tolerability.
Hepatitis D virus (HDV) infection occurs as a simultaneous co-infection or super-infection with HBV. An estimated 12 million patients globally are infected with HDV, representing approximately 5% of those infected with HBV. HDV-HBV co-infection is considered the most severe form of chronic viral hepatitis due to more rapid progression towards hepatocellular carcinoma and liver-related death.
About VIR-2218
VIR-2218 is an investigational subcutaneously administered HBV-targeting siRNA that has the potential to stimulate an effective immune response and have direct antiviral activity against HBV. 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 can 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.
About VIR-3434
VIR-3434 is an investigational subcutaneously administered HBV-neutralizing monoclonal antibody designed to block entry of all 10 genotypes of HBV into hepatocytes and also 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 HBV in infected patients, as well as to have an extended half-life.
