Breast Cancer Neoantigen Vaccination With Autologous Dendritic Cells

In this project, the investigators propose the first clinical study in Colombia of vaccination of patients with triple-negative breast cancer (TNBC) using synthetic peptides that contain mutations of the tumor itself that will be presented to the immune system by autologous dendritic cells to assess immunogenicity and safety of this type of personalized vaccine. Achieving the specific objectives set out in this project will mean that the investigators can validate in Colombia the experimental design necessary to identify exclusive epitopes in the tumors of the participants in this study, and also that have been able to demonstrate the safety and immunogenicity of these vaccines.
