Vir Biotechnology Announces Various Abstracts Highlighting

SAN FRANCISCO, June 07, 2023 (Globe NEWSWIRE) — Vir Biotechnology, Inc. (Nasdaq: VIR) today declared that 5 abstracts highlighting new facts from the Company’s wide hepatitis portfolio addressing both of those hepatitis B virus (HBV) and hepatitis D virus (HDV) have been recognized for presentation at the annual meeting of the European Association for the Analyze of the Liver, EASL™ Congress 2023, getting place in Vienna from June 21-24.

“The accepted abstracts underscore the development Vir is generating with our sturdy hepatitis B and D portfolio and the prospective impact the combination of VIR-3434 and VIR-2218 could have on both of those viruses,” said Phil Pang, M.D., Ph.D., Vir’s Govt Vice President, Chief Clinical Officer and Interim Head of Research. “We look ahead to sharing new details from our scientific progress applications that give us self-confidence in our solution toward a functional overcome for HBV and a therapy for the lengthy-time period suppression of HDV.”

The late-breaker oral presentation, which was accepted as the only HBV-targeted late-breaker abstract, will offer new data relevant to the safety and efficacy of VIR-2218 with or without the need of pegylated interferon alfa (PEG-IFN-α) in virally-suppressed individuals with continual HBV infection.

A next oral presentation will share adhere to-up info from Component A of the Phase 2 MARCH trial. At first offered at the American Affiliation for the Study of Liver Disorders (AASLD) The Liver Meeting^® in November 2022, Part A was intended to, and correctly shown, the on-procedure additivity of VIR-2218 and VIR-3434. Importantly, these quick-length Element A cohorts, in which these investigational treatments ended up co-administered for only 4 or 12 weeks, knowledgeable the protocol for Part B, which is designed to evaluate whether VIR-3434 and VIR-2218, specified with or without the need of PEG-IFN-α for 24 and 48 weeks, can end result in a purposeful cure for long-term HBV. Original on-therapy info from the 24-week cohorts are expected in the 2nd fifty percent of 2023.

Finally, a few poster shows will focus on the prospective efficacy of VIR-2218 and VIR-3434 in preclinical types of HDV, the pharmacokinetics of HBV monotherapy with VIR-3434, and the eligibility and initiation of HBV treatment method in a real-planet placing.

About Continual Hepatitis B
Continual hepatitis B virus (HBV) infection stays an urgent international public wellbeing problem connected with significant morbidity and mortality. About 300 million persons close to the entire world are living with HBV, and approximately 900,000 of them die from associated troubles just about every calendar year. These individuals are substantially underserved by existing therapies with lower useful heal prices, lifelong day-to-day remedy and/or inadequate tolerability. Vir is operating to reach a functional treatment for the hundreds of thousands of people today with HBV all around the globe as a result of its broad and differentiated portfolio.

About Chronic Hepatitis D
Chronic hepatitis D virus (HDV) an infection occurs as a simultaneous co-infection or tremendous-infection with hepatitis B virus (HBV). An estimated 12 million folks globally are contaminated with HDV, symbolizing around 5% of all those contaminated with HBV. HDV-HBV co-an infection is viewed as the most critical form of continual viral hepatitis due to additional speedy development toward hepatocellular carcinoma and liver-associated demise.

About VIR-2218
VIR-2218 is an investigational subcutaneously administered HBV-concentrating on siRNA that Vir believes has the potential to encourage an effective immune reaction and have immediate antiviral action towards HBV and HDV. It is the first siRNA in the clinic to include Increased Stabilization Chemistry Plus (ESC+) engineering to improve balance and lessen off-goal activity, which probably could result in an improved therapeutic index. VIR-2218 is the very first asset in the Company’s collaboration with Alnylam Prescription drugs, Inc. to enter clinical trials.

About VIR-3434
VIR-3434 is an investigational subcutaneously administered antibody created to block entry of hepatitis B and hepatitis D viruses into hepatocytes and to cut down the stage of virions and subviral particles in the blood. VIR-3434, which incorporates Xencor’s Xtend™ and other Fc technologies, has been engineered to likely function as a T cell vaccine versus HBV and HDV, as very well as to have an extended fifty percent-lifestyle.
