Theriva Biologics Inc
therivabio.comTheriva Biologics (NYSE American: TOVX) is a clinical-stage biotechnology company developing oncolytic virus (OV) therapies for cancer. The company generates no product revenue, funding operations through equity issuances, warrant exercises, and Spanish government research and development tax credits and direct reimbursements. Its lead candidate, VCN-01, is an engineered adenovirus being evaluated in pancreatic ductal adenocarcinoma (PDAC) and retinoblastoma; in the VIRAGE Phase 2b trial, VCN-01 combined with gemcitabine/nab-paclitaxel standard of care produced a median overall survival of 10.8 months versus 8.6 months for standard of care alone (FY2025 10-K, filed 2026-03-12). A second candidate, SYN-004, is in a Phase 1a/2a clinical trial. The company also has VCN-12, the first candidate from its VCN-X discovery program. As of the FY2025 filing, cash was projected sufficient to fund operations only into the first quarter of 2027, and the company requires additional capital to advance beyond current trial phases.
