Vir Biotechnology Announces Clinical Advances Across Hepatitis Delta and Hepatitis B Programs at AASLD’s The Liver Meeting® 2024
– Phase 2 SOLSTICE Safety and Efficacy Data in Hepatitis Delta Trial at Week 24 to Be Presented –
– Oral and Five Poster Presentations Highlight Important Progress in Hepatitis Delta and Hepatitis B Clinical Programs, and Deliver Key Insights on the Burden of Disease Among Patient Segments in Hepatitis Delta –
SAN FRANCISCO, October 15, 2024--(BUSINESS WIRE)--Vir Biotechnology, Inc. (NASDAQ:VIR) today announced it will present new data from the Phase 2 SOLSTICE clinical trial evaluating the efficacy and safety profile of tobevibart, an investigational monoclonal antibody (mAb), and elebsiran, an investigational small interfering ribonucleic acid (siRNA) for the potential treatment of chronic hepatitis delta.
These data will be presented in an oral presentation at the upcoming American Association for the Study of Liver Diseases (AASLD) The Liver Meeting®, in San Diego, CA, November 15-19, 2024. Vir will also present five poster presentations that further characterize these investigational therapies as well as recent efforts to improve the assessment and evaluation of hepatitis delta infection, and insights into the economic burden of hepatitis delta for patients and society. Vir will also share advances from across the chronic hepatitis B development program.
"There is an urgent need for effective therapies for people living with hepatitis delta who can face rapid progression to liver cirrhosis and liver cancer. We are excited by the latest data from our hepatitis delta development program, and we look forward to sharing our latest findings at AASLD as we work to help patients living with this debilitating condition," said Mark Eisner, M.D., M.P.H., Executive Vice President and Chief Medical Officer, Vir Biotechnology. "Further, patients living with chronic hepatitis B face lifelong treatment and an increased risk of cirrhosis and liver cancer, so developing a functional cure could transform their lives. We are pleased to share data further characterizing our investigational therapies as we continue on our mission to advance a functional cure."
Vir will be presenting the following abstracts:

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 was identified using Vir’s proprietary antibody discovery platform and has been engineered to have an extended half-life and optimized binding to immune cells. 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 Chronic Hepatitis Delta
Chronic hepatitis delta (CHD) is a long-lasting, inflammatory liver disease caused by the hepatitis D virus (HDV), which requires the presence of hepatitis B virus (HBV) for its replication1. CHD affects nearly 5% of people who have a chronic infection with HBV, and it is considered by the World Health Organization to be the most severe form of chronic viral hepatitis2. Co-infection with HDV accelerates progression towards liver cancer and liver-related death by almost a decade in comparison to HBV mono-infected persons, independently of their age3. There is no cure, and treatment options are limited.

About Chronic Hepatitis B
Chronic hepatitis B (CHB) a is a long-lasting, inflammatory liver disease caused by the hepatitis B virus (HBV)1. The World Health Organization estimates that 254 million people were living with CHB infection in 2022, with 1.2 million new infections each year, and an estimated 1.1 million yearly deaths associated to the disease2. Complications from CHB may include liver cirrhosis, liver failure and liver cancer3. Although CHB can be treated, there’s no cure available today1.
