Brief Summary:

Chimeric Antigen Receptor T Cells (CART) Therapy in GUYC2C postive Digestive system tumors, include colorectal cancer, gastric cancer, liver cancer, pancreatic cancer, adenocarcinoma of esophagus, cancer of the esophagogastric junction.

Ict-gc is an open, single-center study to evaluate the safety and efficacy of CAR-T-targeted therapy in patients with advanced gastrointestinal tumors.

Condition or disease Intervention/treatment Phase
Malignant Neoplasms of Digestive Organs Biological: gucy2c cart cells Not Applicable

Detailed Description:
The primary objective of phase 1 is to evaluate the safety of CART regimens. The primary objective of phase 2 is to evaluate the efficacy of CART, as measured by objective response rate in subjects with colorectal cancer. Secondary objectives will include assessing the safety and tolerability of CART and additional efficacy endpoints.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 20 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Chimeric Antigen Receptor T Cells (CART) Therapy in GUCY2C Positive Digestive System Tumors
Estimated Study Start Date : March 2021
Estimated Primary Completion Date : April 2022
Estimated Study Completion Date : March 2026

Arm Intervention/treatment
Experimental: Patients with late malignant digestive tract tumor
Patients with late malignant digestive tract tumor, for example metastatic colorectal cancer, pancreatic cancer, gastric cancer and so on. because of this is a open, single arm trail, there is no control group.
Biological: gucy2c cart cells
Patients with advanced malignant gastrointestinal tumors were injected with CART cells

Primary Outcome Measures :
  1. Number of participants with CAR-T treatment-related adverse events as assessed by CTCAE v4.03 [ Time Frame: 24 months ] [ Time Frame: 24 months ]
    The investigator is responsible for ensuring that all adverse events observed by the investigator or reported by the subject during the 3-month period from enrollment (i.e. initiation of leukocyte separation) to 3 months after targeted car-t infusion are monitored and reported. After three months, researchers will be required to monitor and report targeted adverse events, including neurological, blood, infection, autoimmune diseases, and secondary malignant tumors, for 24 months or until disease progression, whichever occurs first.

Secondary Outcome Measures :
  1. The event of cytokine release syndrome was reported using the grading scale in the protocol. [ Time Frame: 24 months ]
    We will summarize the classification of cytokine release syndrome (CRS) according to the severity and system organ classification.

  2. Efficacy will be assessed according to RECIST1.1 or EORTC or PERCIST criteria [ Time Frame: 24 months ]
    Remission will be evaluated by the central investigator at the time indicated in the evaluation plan. The disease was evaluated according to the response evaluation criteria in solid tumors RECIST version 1.1 or EORTC or percist. Flow cytometry, molecular or cytogenetic studies used in the trial will be used to assist, but will not be used alone to determine remission.
