Immunotherapy Using Pluripotent Killer-Human Epidermal Growth Factor Receptor-2 (PIK-HER2) Cells for the Treatment of Advanced Gastric Cancer With Liver Metastasis

Second Military Medical University40 enrolled

Overview

Objectives: The purpose of this study is to evaluate the safety and efficacy of PIK-HER2 cells in the treatment of advanced Her2 high expressed gastric cancer with liver metastasis patients. Methods: This study designs a novel therapy using PIK-HER2 cells. 40 Her2 positive patients with liver metastasis from gastric cancer will be enrolled. They are randomly divided into dendritic cell-precision multiple antigen T cells (DC-PMAT) group and PIK-HER2 cells group. Both DC-PMAT treatment and PIK-HER2 cells treatment will be performed every 3 weeks with a total of three periods. The mail clinical indicators are Progression-Free-Survival and Overall Survival.

A total of 40 patients may be enrolled over a period of 1-2 years.
