Its lead clinical candidate is VTP-1000, which is being evaluated in the Phase 1 AVALON trial for the treatment of celiac disease. Additionally, the company is developing VTP-300, a viral vector-based immunotherapy in Phase 2 clinical trials aimed at achieving a functional cure for chronic hepatitis B virus (HBV) infections.

Strategic Initiatives
Growth programs, investments, and their expected impact
In January 2025, Barinthus Bio announced a strategic business refocus and restructuring to prioritize immunology and inflammation (I&I) indications, specifically antigen-specific immune tolerance and the development of VTP-1000 in celiac disease. Infectious disease and oncology assets (collectively referred to as 'Barinthus legacy assets'), including VTP-300 in chronic hepatitis B and VTP-850 in prostate cancer, were deprioritized for direct operations and will only be progressed with a partner.
Expected impact: Significantly reduced operating expenses (R&D and G&A) and extended the standalone cash runway.
