Brief Summary:
The primary objectives are to evaluate the safety and efficacy of infusion of autologous tumor associated antigen-specific engineered immune effector cells (EIE).

Condition or disease Intervention/treatment Phase
Cancer Biological: Engineered Immune Cells Phase 1 Phase 2

Detailed Description:

Malignant tumor is still a major challenge in medicine and requires technology breakthrough, and its mortality rate is the highest among all diseases. World Health Organization and the American Cancer Association expect about 12 million new cancer patients worldwide each year, with about 8 million cancer deaths (20 thousand cancer deaths per day). At present, more than 20 million people are suffering from cancer, and this figure will increase to 75 million in 2030. In Asia, the incidence of cancer is expected to rise by 60% in 2020, and the number of cancer related deaths will reach 7 million annually in 2030. The incidence of lung, Intestine, breast, prostate and gastric cancer is high, and lung, Intestine, breast and liver cancer are the main causes of cancer related deaths in Asia.

Adoptive immunotherapy based on cytotoxic T lymphocytes reactive with specific antigens has proven to be effective. In vitro induction of tumor antigen-specific immune cells and engineering of target specific immune cells have great potential for cancer eradication. The 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 injection. 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.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. percentage of adverse effects after EIE cell injection [ Time Frame: up to one month ]
    To assess the safety of autologous EIE cells in vivo. The percentage of patients who have adverse effects will be evaluated by using the NCI CTCAE V4.0 criteria.


Secondary Outcome Measures :
  1. Rate of successful EIE generation [ Time Frame: up to one month ]
    The percentage of successful EIE generation, which are derived from subjects and pass the safety test after standard culture procedures, viable for at least one preparation, will be evaluated.

  2. Ability of EIE cells to induce anti-cancer reaction [ Time Frame: after 1 month from EIE cells infusion until 12 months after infusion ]
    measurement of TAA concentration in blood sample

  3. Ability of EIE cells for anti-cancer reaction [ Time Frame: after 1 month from EIE cells infusion until 24 months after infusion ]
    Objective response (complete response (CR) + partial response (PR)) was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria. CR is disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial response is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.
