Important Regulatory Notice:
This trial record is only for global academic information registration on ClinicalTrials.gov. Neither the sponsor Beijing Meikang Jimian Biotechnology Co., Ltd. nor collaborator Shenzhen Geno-Immune Medical Institute has obtained NMPA clinical trial approval or clinical technology filing permission to carry out interventional cell therapy trials in mainland China.

Gastro-intestinal (GI) cancer is becoming the top-ranked high mortality cancer in recent years. Every year, approximate 5,300,000 people in China are diagnosed with cancer, of which about 2,000,000 die each year, and esophagus cancer, gastric cancer and colorectal cancer account for ~50% of all GI cancer cases. GI cancer causes 500 thousand deaths a year. In China, nearly 85% of patients with cancer of the digestive tract are in middle to late stage at diagnosis. Regardless of the treatment, the five year survival rate is only 36%. GI cancers include cancer in the oral cavity, pharynx, esophagus, stomach, small intestine (duodenum, jejunum, ileum) and large intestine (cecum, colon, rectum). The main malignant tumors of the GI tract are esophageal, gastric, colorectal, liver, and pancreatic cancer.
Adoptive immunotherapy based on cytotoxic T lymphocytes reactive with specific antigens has proven to be effective in many studies. In vitro induction of cancer antigen-specific immune cells and genetic engineering of target specific immune cells have great potential for cancer eradication. This study aims to evaluate the safety and efficacy of ex vivo manipulated EIE cells including chimeric antigen receptor (CAR) modified immune cells in treating cancer. The primary study objectives are to evaluate the safety of the investigational product, autologous EIE cells, to subjects by intravenous and intratumoral injections. The secondary study objectives are (1) to evaluate the success rate of generating autologous EIE cells ex vivo, and (2) to determine the anti-cancer efficacy of the EIE cells.
