Study & Design

Arm && Interventions

Group	Intervention	Description
KD-025	NKG2D-based CAR T-cells	NKG2D-based CAR T-cells Injection; Dosage:1-10x10\^6/kg, 70ml/time, The CAR-T cells will be administered by i.v. or hepatic portal artery injection over 20-30 minutes Frequency: total one time

Primary Outcome Measures

Name	Time	Method
Number of participants with treatment-related adverse events as assessed by CTCAE v4.0	through study completion, an average of 3 months.	The number of patiens who suffered ≥ 3 grade toxicities according to the CTCAE criteria after CAR-T therapy.
Detailed adverse events post NKG2D-based CAR-T therapy.	through study completion, an average of 3 months.	The events included infusion reactions, CRS, tumor lysis syndrome and hematological toxicity. The criteria mainly reffered to guidelines for immune related adverse reactions.

Secondary Outcome Measures

Name	Time	Method
Partial response rate	through study completion, an average of 3 months.	According the RECISE 1.1 criteria, as to the measurable primary lesions, we measure the long and short diameter. As to unmeasurable primary leisons, we measure the measurable metastatic lesions.
Progress Free Survival (PFS)	2 years post infusion	Progress Free Survival after administration
overall survival (OS)	2 years post infusion	For all subjects, overall survival refers to the period from being included in the test group to death caused by any reason
