Vir Biotechnology said its pivotal Phase 3 ECLIPSE 1 trial of elebsiran and tobevibart in adults with chronic hepatitis delta met its primary and key secondary endpoints, with data presented at the AASLD Liver Meeting on November 8, 2026. The company also released expanded Phase 2 SOLSTICE data and preliminary, exploratory findings on treatment discontinuation, which the company itself says are interim and not a complete assessment of safety or efficacy.
ECLIPSE 1 primary endpoint: 44% of patients on elebsiran and tobevibart reached undetectable virus plus ALT normalization at Week 48, versus 0% in the delayed treatment group at Week 12 (p<0.0001)
Key secondary endpoint: 79% reached undetectable virus at Week 48, versus 0% in the delayed treatment group
SOLSTICE Week 96: 100% (28/28) of patients who completed Week 96 of combination therapy reached undetectable viremia
Exploratory analysis: 10 patients discontinued treatment; all 10 achieved SVR12, with 7 reaching SVR24 and 1 reaching SVR48; the filing states these data are preliminary and not a claim of cure
