VRON-0200: Treatment of HBV Infection

The T Cell Platform for Multi-Modal Therapies & Functional Cure

VRON-0200 is designed to address a global high unmet medical need for chronic HBV infection. VRON-0200 combines a genetically encoded checkpoint modifier along with selected and optimized antigens of choice and delivered by ChiVax™, our heterologous chimpanzee adenoviral vectors that promotes potent, prolonged, and broad CD8+ T cell responses.
