The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Chimeric antigen receptor modified T (CAR-T) cells have the capability in targeting and recognizing tumor antigen, and can specifically recognize, bind and kill tumor cells with positive antigen. Through local drug delivery, CAR-T cells have successfully achieved remarkable effect to treat solid tumors. Gastric cancer is one of the most frequent malignant tumors with high mortality, especially in China. Peritoneal metastasis is one of the common routes of metastasis. Once peritoneal metastasis occurred, patients should be categorized as clinical pathological stage IV with extremely poor prognosis, and the effect of routine treatments would be unsatisfactory. Epithelial cell adhesion molecule (EpCAM) is highly expressed in gastric cancer cells and closely associated with the poor prognosis of patients. In our previous pre-clinical research researches, the investigators have obtained CAR-T cells targeting EpCAM (EpCAM CAR-T), and finished the preparations of cells which could be used in clinical practice. Based on our previous works, the investigators aim to investigate the safety and efficacy of peritoneal infusion of EpCAM CAR-T cell in advanced gastric cancer with peritoneal metastasis by a prospective nonrandomized controlled trial. The results of this clinical trial are expected to provide the new treatment strategy for gastric cancer patients with peritoneal metastasis.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
