Study Evaluating the Efficacy and Safety With CAR-T for Liver Cancer

Study Overview
=================
Brief Summary
-----------------
This single-arm,multicenter Phase 2 trial will treat the patients who have relapsed or refractory liver cancer with an infusion of the patient's own T cells that have been genetically modified to express a chimeric antigen receptor(CAR)that will bind to tumour cells that express the EPCAM protein on the cell surface.The study will determine if these modified T cells help the body's immune system eliminate tumour cells.The trial will also study the safety of treatment with CAR-T,how long CAR-T cells stay in the patient's body and the impact of this treatment on survival.

Detailed Description
-----------------
This is a single-arm,multicenter Phase 2 study to evaluate the efficacy and safety of the CAR-T for Liver Cancer.The study will be conducted using a phaseⅠ /Ⅱ disign.The study will have the following sequential phases:Part A(screening leukapheresis,cell product preparation,and cytoreductive chemotherapy) and Part B(treatment and follow-up).The follow-up period for each paticipant is approximately 35 months after the final CAR-T infusion.The total duration of the study is expected to be approximately 3 years.A total of 25 patients may be enrolled over a period of 3 years.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Single-arm<br>Name:The Chimeric Antigen Receptor T Cell Immunotherapy (CAR-T) Dosage form：injection Dosage:100ml/time Frequency:0 days,the first day,the second day,28days,29days Duration:total five times | Biological: EPCAM-targeted CAR-T cells<br>* This study have only one arm that is CAR-T experimental arm. Firstly all participators will be attended the screening, who passed the screening for the treatment of CAR-T cells, the CAR-EPCAM-modified T cells can recognize and kill tumor cells in the body，follow-up 35 months.<br>|
