• Vir Biotechnology's tobevibart and elebsiran combination achieved 100% virologic suppression in chronic hepatitis delta (CHD) patients at Week 24, sustained through Week 60.
• HDV RNA was undetectable in 41% of participants at Week 24, increasing to 80% by Week 60, indicating potential viral clearance with the combination therapy.
• The combination therapy was well-tolerated, with no treatment-related severe adverse events, discontinuations, or ALT flares reported during the trial.
• Vir Biotechnology plans to initiate a Phase 3 registrational program (ECLIPSE) in the first half of 2025 to further evaluate the combination for CHD treatment.
