Virion Therapeutics announced at CROI 2026 that a single intramuscular dose of VRON-0200, its novel, first-in-class, immunotherapy for HBV functional cure was able to “spark” and re-awaken durable HBV-specific immunity in the majority of chronically HBV-infected patients – with HBsAg declines that were sustained or deepened through Day 360. These data, presented as a late breaker presentation, also highlighted VRON-0200’s ongoing favorable safety and tolerability profile, and its rapid and profound synergy when combined with antigen lowering antiviral agents.
Aligos Therapeutics announced positive data from two presentations at CROI 2026. The pevifoscorvir sodium presentation highlighted the Phase 1 monotherapy study of pevifoscorvir sodium, a potent CAM-E under development for the treatment of chronic hepatitis B virus (HBV) infection. Additionally, the ALG-097558 presentation (ALG-097558: Potential best-in-class ritonavir-free small molecule pan-coronavirus protease inhibitor) showcased data from participants with hepatic and renal impairment.
Atea Pharmaceuticals announced at CROI 2026 in vitro results showing that two proprietary oral nucleotide analogs, AT-587 and AT-2490, exhibit promising antiviral profiles as potential first-in-class inhibitors for the treatment of hepatitis E virus infection, a positive-sense, single-stranded RNA virus that primarily infects liver cells.
