Elebsiran

Agreement underscores Norgine's mission to bring innovative therapies to patients and builds on our heritage in hepatology and specialty pharmaceuticals. Vir Biotechnology's chronic hepatitis delta treatment candidate has shown robust virological responses and reflects a differentiated approach to treatment. UXBRIDGE, England, Dec. 17, 2025 /PRNewswire/ -- Norgine, a leading European specialty pharmaceutical company, today announced an exclusive licensing agreement under which Norgine will commercialise the combination of tobevibart and elebsiran for the treatment of chronic hepatitis delta (CHD) in Europe, Australia and New Zealand following the necessary marketing authorisations. There is a high unmet medical need for effective treatments for CHD given potential limitations with existing treatment options. Under the terms of the licensing agreement, Vir Biotechnology will receive a EUR 55 million initial reimbursement payment and up to EUR 495 million in potential regulatory and commercial milestone payments. Additionally, Vir Biotechnology will receive tiered, mid-teen to high-twenties percent royalties on net sales in Norgine's licensed territories. Clinical development costs for the ongoing trials in Vir Biotechnology's ECLIPSE registrational program (ECLIPSE 1, 2 and 3) will be shared, with Norgine contributing a percentage of go-forward external costs. Norgine will be responsible for all commercialisation activities and will hold all marketing authorisations in its licensed territories. The closing of this transaction with respect to certain jurisdictions outside the United States is subject to Norgine receiving regulatory approval from the applicable authorities as may be required. "Norgine has a rich history in hepatology and specialty care and this transaction represents a highly innovative and synergistic portfolio addition to continue our strong foothold in this space," said Janneke van der Kamp, Chief Executive Officer of Norgine. "By combining our proven commercial and regional expertise with cutting-edge science from Vir Biotechnology, we are reinforcing our commitment to improving healthcare outcomes. Collaborations like this affirm Norgine's position as a partner-of-choice for companies seeking a trusted collaborator in Europe, Australia and New Zealand." "This collaboration strengthens our ability to deliver this important therapy to patients with chronic hepatitis delta in need of efficacious, safe and convenient treatment options," said Marianne De Backer, M.Sc., Ph.D., MBA, Chief Executive Officer, Vir Biotechnology. "Norgine's proven track record in specialty medicines across Europe, Australia and New Zealand complements our clinical development mettle and ongoing registrational efforts. Together, we aim to broaden access and improve outcomes for people living with this severe disease." The combination of tobevibart and elebsiran offers the potential to treat the disease by tackling the viral lifecycle through multiple mechanisms. Tobevibart is an investigational neutralising monoclonal antibody that has been engineered for immune engagement. Elebsiran is an investigational small interfering RNA (siRNA) that is designed to enable targeted delivery to the liver and to reduce hepatitis B surface antigen, a protein which is required for the hepatitis D virus life cycle. About Tobevibart and Elebsiran 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. 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 indicate 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 (CHD). The combination of tobevibart and elebsiran has been granted Breakthrough Therapy and Fast Track designations by the U.S. Food and Drug Administration (FDA), and Priority Medicines (PRIME) and orphan drug designations by the European Medicines Agency (EMA). About Chronic Hepatitis Delta (CHD) CHD is the most severe form of chronic viral hepatitis1 and was recently classified as carcinogenic by the International Agency for Research on Cancer.2 People living with the disease rapidly progress to cirrhosis, liver failure3 and liver-related death.1 There are currently no approved treatments in the U.S., and options are limited in the European Union and globally. About Norgine Norgine is a mid-sized EU-based pharmaceutical company with 1,500 employees, generating approximately $600 million in annual sales. At Norgine, innovation drives our mission to deliver medicines that change lives. From common conditions like constipation to rare and severe diseases such as childhood cancer, we target unmet medical needs because we believe that every scientific breakthrough deserves to reach patients in need. We use our innovative development, commercialisation and manufacturing capabilities as well as strategic partnerships to navigate complex pathways. Combined with our extensive history and deep regional expertise, this approach allows us to accelerate and expand the reach of life-changing medicines across Europe, Australia, and New Zealand. We are guided by the trust that healthcare professionals and patients place in us and remain committed to delivering innovation that transforms lives, one patient at a time.
