Tumor-Specific Delivery of 5-Fluorouracil–Incorporated Epidermal Growth Factor Receptor–Targeted Aptamers as an Efficient Treatment in Pancreatic Ductal Adenocarcinoma Models

Abstract

Tumor-specific targeted delivery of 5FU using EGFR aptamers as the carrier achieved high target specificity; overcame 5FU resistance; and proved to be effective in a syngeneic orthotopic transplantation model, in KPC mice, in a CDX model, and in patient-derived organoids and, therefore, represents a promising backbone for pancreatic cancer chemotherapy in patients. Furthermore, our approach has the potential to target virtually any cancer entity sensitive to 5FU treatment by incorporating 5FU into cancer cell-targeting aptamers as the delivery platform.
