Trial is entitled "A Phase IIa, single-arm, single-center, open-label, proof-of-concept trial evaluating increased frequency dosing of zabilugene almadenorepvec (VCN-01) in combination with gemcitabine/nab-paclitaxel in patients with newly-diagnosed metastatic pancreatic cancer" (EUCT: 2026-525566-21-00).

The VIRAGE2 trial builds on the results of the 112-patient VIRAGE Phase 2b clinical trial evaluating VCN_01 in treatment naïve metastatic pancreatic ductal adenocarcinoma (PDAC) patients receiving gemcitabine/nab-paclitaxel standard-of-care (SoC) chemotherapy. In the VIRAGE trial, patients who received 2 doses of VCN-01 administered 3 months apart had significantly improved overall survival, progression free survival, and duration of response compared to patients treated with only one dose of VCN-01 or with SoC chemotherapy alone. As previously reported, both the EMA and the FDA recognized the improved survival in the group treated with 2 doses of VCN-01, and raised the possibility of more frequent repeated dosing of VCN-01 in combination with SoC chemotherapy to potentially improve clinical outcomes. The VIRAGE2 trial is designed to evaluate the feasibility of administering at least 3 doses of VCN-01 given 2 months apart in combination with SoC chemotherapy (see About VIRAGE2). Results from this trial will inform the VCN-01 dosing regimen for potential evaluation in a future pivotal Phase 3 clinical trial.
