Tune Therapeutics Unveils Promising Data for Hepatitis B Treatment at EASL 2026
Tune Therapeutics has presented positive Phase 1b/2a proof of concept data for TUNE-401, an epigenetic silencer for hepatitis B, at the European Association for the Study of Liver (EASL) Congress. The study demonstrated deep and durable antiviral activity, including direct silencing of cccDNA, a key barrier to curing chronic hepatitis B (CHB). TUNE-401, delivered intravenously, showed dose-dependent repression of HBV biomarkers and was well-tolerated in patients. The trial included single and multiple-dose cohorts, with biomarker repression observed in 100% of participants at higher dose levels. The study's findings suggest a potential pathway to a finite cure for HBV patients.
