Immunotherapy Using Pluripotent Killer-Programmed Cell Death 1 (PIK-PD-1) Cells for the Treatment of Advanced Hepatocellular Carcinoma

A Clinical Study of Adoptive Cellular Immunotherapy Using Pluripotent Killer T Cells Expressing Antibodies for Programmed Death 1 (PD-1) in Treating Patients With Advanced Hepatocellular Carcinoma

Objectives:

The purpose of this study is to evaluate the safety and efficacy of PIK-PD-1 Cells in the treatment of advanced Hepatocellular Carcinoma.

Methods:

This study designs a novel therapy using PIK-PD-1 cells. 40 patients with advanced Hepatocellular Carcinoma will be enrolled. They are randomly divided into dendritic cell-precision multiple antigen T cells (DC-PMAT) group and PIK-PD-1 cells group. Both DC-PMAT treatment and PIK-PD-1 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.

Inclusion Criteria:

• 1. Age 20~70 years old, male or female; 2.
