Frequently asked questions about VCN-01

What is VCN-01 used for?

VCN-01 is an investigational gene therapy being studied for locally advanced and metastatic solid tumors, with the main focus on pancreatic cancer, including metastatic pancreatic adenocarcinoma. It is also being evaluated in serous ovarian cancer. It is not an approved treatment and remains in clinical development.

Who makes VCN-01?

VCN-01 is developed by Theriva Biologics, Inc., which trades on the NYSE American under the ticker TOVX. The company is the sponsor of the clinical program evaluating VCN-01 in pancreatic cancer and other solid tumors.

What phase is VCN-01 in?

VCN-01 is in Phase 1 clinical development, with a Phase 2 study also completed in metastatic pancreatic cancer. It is investigational and has not been approved by the FDA. The program includes completed, active, and recruiting trials across the United States and Spain.

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 NCT05057715, an active Phase 1 study with huCART-meso in pancreatic and ovarian cancer. Completed studies include NCT05673811 and NCT02045602.

Is VCN-01 the same as zabilugene almadenorepvec?

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

What FDA designations has VCN-01 received?

VCN-01 has received Fast Track, Orphan Drug, and Rare Pediatric Disease designations from the FDA. These designations support the development program in pancreatic cancer and other solid tumor indications, though VCN-01 remains investigational and is not approved.
