Immunotherapy Using Precision T Cells Specific to Personalized Neo-antigen for the Treatment of Advanced Malignant Tumor of Biliary Tract

December 30, 2015 updated by: Second Military Medical University

A Clinical Study of Adoptive Cellular Immunotherapy Using Precision T Cells Specific to Personalized Neo-antigen in Treating Patients With Advanced Malignant Tumor of Biliary Tract

Objectives:

The purpose of this study is to evaluate the safety and prognosis of dendritic cell-precision T cell for neo-antigen in the treatment of advanced biliary tract malignant tumor.

Methods:

This study designs a novel therapy using dendritic cell-precision multiple antigen T cells. 40 patients will be enrolled. They are randomly divided into gemcitabine group and dendritic cell-precision T cell for neo-antigen combined with gemcitabine group. Gemcitabine treatments will be performed once a week with a total of six times. Dendritic cell-precision T cell for neo-antigen combined with gemcitabine treatment: Gemcitabine: once a week with a total of six times before 60 days prior to the start of drawing blood. Dendritic cell-precision T cell for neo-antigen: once per 3 weeks with a total of three periods. The mail clinical indicators are Progression-Free-Survival and Overall Survival.
