Theriva Biologics stock soars after EMA backs Phase 3 trial design

Theriva Biologics Inc. stock surged 25.4% in premarket trading after the European Medicines Agency (EMA) provided positive scientific advice on the company's proposed Phase 3 clinical trial design for VCN-01 in pancreatic cancer treatment. The EMA agreed with key elements of the trial design, including sample size and a "macrocycle" dosing regimen allowing for multiple doses of VCN-01. Theriva plans to engage with the FDA in early 2026 to finalize the protocol for the multinational Phase 3 trial and is also seeking advice for a potential Phase 2/3 trial for VCN-01 in retinoblastoma.
