Virion Therapeutics announced at CROI 2026 that its novel immunotherapy, VRON-0200, demonstrated broad and sustained anti-HBV immunity in most chronically infected patients after a single dose. The treatment showed significant HBsAg declines lasting up to 360 days and maintained a favorable safety profile. The company aims to develop VRON-0200 as a foundational agent in future HBV treatment strategies, potentially reducing the need for rescue medications. A Phase 2b trial is planned to further evaluate its efficacy in combination with antiviral therapies.
