General Description

This study aims to utilize SSTR2 receptors present on pancreatic NETs to target and deliver therapeutic agents directly to the tumors themselves. Researchers will first design a virus containing octreotide on its protein surface, which will allow the virus to bind to cells containing SSTR2 receptors (i.e. pancreatic NETs). The virus will contain the gene for TNF-a, a protein that induces cell inflammation and death. The intended goal is that the virus will selectively target pancreatic NETs via the SSTR2 receptor, deliver the TNF-a gene, and in tum cause cell death without harming surrounding healthy cells. The successful completion of this study will address the lack of a gene therapy approach to the treatment of pancreatic NETs.
