Frequently asked questions about VCN-01

What is VCN-01?

VCN-01 is an investigational oncolytic adenovirus developed by Theriva Biologics, Inc. (TOVX) as a gene therapy for cancer. It is being studied in locally advanced and metastatic solid tumors, with the main clinical focus on pancreatic cancer, including metastatic pancreatic adenocarcinoma. It is not an approved product and remains in clinical development.

What is VCN-01 used for in pancreatic cancer?

VCN-01 is being studied for pancreatic cancer, particularly metastatic pancreatic adenocarcinoma and newly diagnosed metastatic pancreatic ductal adenocarcinoma. Trials combine it with standard chemotherapy regimens such as nab-paclitaxel and gemcitabine, and one study pairs it with huCART-meso cells in pancreatic and ovarian cancer. All use remains investigational.

Who makes VCN-01?

VCN-01 is developed by Theriva Biologics, Inc., which trades under the ticker TOVX. The company sponsors the clinical program evaluating the agent in pancreatic cancer and other advanced solid tumors across studies in the United States and Spain.

What phase is VCN-01 in?

VCN-01 is in Phase 1 and Phase 2 clinical development. The Phase 2 study of nab-paclitaxel and gemcitabine with or without VCN-01 in metastatic pancreatic cancer has completed, while a Phase 1 study of more frequent VCN-01 dosing with standard chemotherapy in newly diagnosed metastatic pancreatic cancer is recruiting.

What clinical trials is VCN-01 in?

VCN-01 trials include NCT07701486, a recruiting Phase 1 study of more frequent dosing with standard chemotherapy in newly diagnosed metastatic pancreatic cancer in Spain, and NCT05673811, a completed Phase 2 study with nab-paclitaxel and gemcitabine. NCT05057715 tested huCART-meso plus VCN-01, and NCT02045602 was an intravenous dose escalation study.

Is VCN-01 the same as zabilugene almadenorepvec?

Yes. VCN-01 is also known as zabilugene almadenorepvec, and it is described as a VCN-01 oncolytic adenovirus. These names refer to the same investigational gene therapy developed by Theriva Biologics for solid tumors and pancreatic cancer.
