A double-blind randomized comparative clinical trial to evaluate the safety and efficacy of dendritic cell vaccine loaded with WT1 peptides (TLP0-001) in combination with S-1 in patients with advanced pancreatic cancer refractory to standard chemotherapy

摘要

BackgroundPancreatic cancer is a refractory malignancy, and the development of a new effective treatment strategy is needed. We generated a dendritic cell vaccine by culturing monocytes obtained by apheresis of blood from each patient, inducing their differentiation into dendritic cells, and pulsing with tumor antigen peptides. However, the clinical efficacy of the vaccine has not been established. We therefore decided to conduct an exploratory clinical trial of dendritic cell vaccine loaded with Wilms’ tumor gene 1 peptides (TLP0-001) as a potential new treatment for patients with advanced pancreatic cancer refractory to standard chemotherapy.
