Theriva Biologics Reaches Agreement with FDA on VCN-01 Phase 3 Trial Design

Theriva Biologics announced the outcomes of a recent Type B End-of-Phase 2 meeting with the FDA regarding the design of a Phase 3 clinical study of lead clinical candidate VCN-01 in combination with standard-of-care chemotherapy for the treatment of metastatic pancreatic adenocarcinoma. The FDA provided general agreement with Theriva's proposed design for a Phase 3 clinical trial, which closely tracks the design of the successful VIRAGE Phase 2 trial. As announced in 2025, the VIRAGE trial met its primary endpoints, with metastatic PDAC patients receiving VCN-01 with SoC chemotherapy having improved overall survival, progression free survival and Duration of Response compared to SoC chemotherapy alone. Greater improvements in OS and PFS were observed in patients who received two doses of VCN-01, leading Theriva to plan the Phase 3 trial to include repeat dosing and an adaptive design aimed to optimize the trial's timelines and outcomes. Consistent with scientific advice previously received from the Committee for Medicinal Products for Human Use of the European Medicines Agency, the FDA advised that a potential biologics licensing application for VCN-01 in metastatic PDAC could be supported by Theriva's proposed Phase 3 clinical trial comprising a single, high-quality, randomized, double-blinded, study comparing VCN-01 plus gemcitabine/nab-paclitaxel SoC to gemcitabine/nab-paclitaxel SoC plus placebo. The FDA further agreed on the proposed dosing of VCN-01 and gemcitabine/nab-paclitaxel in repeated "macrocycles", the proposed inclusion/exclusion criteria, the primary endpoint (overall survival), key secondary endpoints, and the use of an adaptive design. The FDA also clarified statistical expectations regarding the proposed interim analyses and the quality of data required for potential sample size re-estimation or a demonstration of early efficacy.

SYN-020 Licensed to Rasayana Therapeutics, Advancing Oncology Drug Development

"We are very pleased to have completed the licensing of our versatile Phase 2-ready asset SYN-020 to Rasayana Therapeutics, executing on our plan to derive value from our GI portfolio while we remain focused on the advancement of our oncology pipeline," said Steven A. Shallcross, CEO. "We continue to advance our lead oncolytic virus candidate VCN-01 towards pivotal clinical development in multiple indications of high unmet need. With the recent feedback from the EMA, we have further clarity on dosing regimen, protocol and overall design for our proposed Phase 3 trial in pancreatic ductal adenocarcinoma. An End-of-Phase 2 meeting with the FDA is planned for the first half of 2026 to finalize our design for a multinational pivotal Phase 3 trial in PDAC, aiming to provide patients with a novel therapy for this difficult to treat solid tumor that has a high mortality rate. Additional interactions with the FDA and EMA are planned for 2026 to refine the design of a potential Phase 2/3 trial for retinoblastoma, for which VCN-01 has received Orphan Drug and Rare Pediatric Disease designation. We continue to engage in potential partnership discussions for the additional innovative drug candidates in our portfolio."
