VXM01 Phase I Dose Escalation Study in Patients With Locally Advanced, Inoperable and Stage IV Pancreatic Cancer

VXM01 Phase I Dose Escalation Study in Patients With Locally Advanced, Inoperable and Stage IV Pancreatic Cancer to Examine Safety, Tolerability, and Immune Response to the Investigational VEGFR-2 DNA Vaccine VXM01

First-in-human phase I dose escalation study in patients with locally advanced, inoperable and stage IV pancreatic cancer to examine safety, tolerability, and immune response to the investigational VEGFR-2 DNA vaccine VXM01 to examine safety and tolerability, clinical and immunogenic response to the investigational vascular endothelial growth factor receptor 2 (VEGFR-2) DNA vaccine VXM01, and to define the maximum tolerated dose.
