Outcome Measures

Primary Outcome Measures

Incidence of Treatment Related adverse events (AEs) [Up to 28 days after CAR-T cell infusion]
Incidence of treatment related AE.

Secondary Outcome Measures

Objective response rate (ORR) [Up to 24 weeks after CAR-T cell infusion]
ORR, defined as the proportion of participants with a complete response or partial response, as determined by the investigator according to RECIST v1.1
Progression-free survival (PFS) [Up to 24 weeks after CAR-T cell infusion]
PFS, defined as the time from CAR-T cell infusion to the first occurrence of disease progression or death from any cause (whichever occurs first) , as determined by the investigator according to RECIST v1.1
Duration of Response (DOR) [Up to 24 weeks after CAR-T cell infusion]
DOR, defined as the time from the first occurrence of a documented objective response to disease progression or death from any cause (whichever occurs first) in Stage 1, as determined by the investigator according to RECIST v1.1
Overall survival (OS) [Up to 24 weeks after CAR-T cell infusion]
OS , defined as the time from CAR-T cell infusion to death from any cause
Persistence of CAR-T cells (cell counts and cell percentage in peripheral blood) [Up to 24 weeks after CAR-T cell infusion]
The persistence over time of CAR T cells in the peripheral blood as determined by flow cytometry and qPCR.

Exclusion Criteria:

Patients have brain metastasis；
Patients with a history of organ transplantation or awaiting organ transplantation;
The side effects caused by the previous treatment of the subjects did not return to CTCAE ≤1; other tolerable events determined by investigator;
There is a large amount of serous effusion that cannot be controlled by treatment (such as pleural effusion, peritoneal effusion and pericardial effusion);
History of autoimmune disease (eg Crohn's disease, rheumatoid arthritis, systemic lupus) within the last 2 years;
Presence of acute or chronic graft-versus-host disease (GVHD);
Use prohibited drugs or treatments within a specified period of time before cell collection；
History or presence of CNS disorder, such as epilepsy, epileptic seizures, cerebrovascular disease (ischemia / hemorrhage / cerebral infarction), brain edema, reversible posterior white matter encephalopathy, paralysis, aphasia, stroke, severe brain injury, dementia, Parkinson's disease, cerebellar disease, cerebral organic syndrome or mental disease;
Chronic or active infections requiring systemic treatment, and a history of symptomatic viral infection that has not been completely cured；
Live vaccine received within 6 weeks before the start of screening;
Cardiac dysfunction includes: long QTc syndrome or QTc interval > 480 MS; Complete left bundle branch block, grade II / III atrioventricular block; Serious and uncontrolled arrhythmias requiring drug treatment; A history of chronic congestive heart failure with NYHA ≥ 3, and the cardiac ejection fraction was less than 50% within 6 months before screening; Cardiac valvular disease with CTC AE ≥ 3; Myocardial infarction, cardiac angioplasty or stenting, unstable angina pectoris, history of severe pericardial disease or other clinically significant heart diseases within 6 months before screening;
