This is a single arm, open-label, early phase I study, to determine the safety and efficacy of Novel CAR-T cell therapy in Hematological Malignancy treatment.

The Novel CAR-T contains either a scFv plus a PD-L1 blocker, or two scFvs, in a cytokine complex based outer memberane structure, this kind of structure enables the CAR-T cells to simultaneously target one or two targets on the tumor cell surface and enhance CAR-T cell persistence in tumor microenvironment，as well as stimulating innate T/NK cell activation and expansion.

Inclusion Criteria:

1. All subjects must personally sign and date the consent form before initiating any study specific procedures or activities;

2. All subjects must be able to comply with all the scheduled procedures in the study;

3. Clear diagnosis of hematological malignancy, including B-cell Non-Hodgkin lymphoma, B-cell lymphoblastic leukemia, multiple myeloma.

5. At least one clear indicator for hematological malignancy monitoring;

6. Aged <70 years;

7. Expected survival ≥12 weeks;

8. Eastern cooperative oncology group (ECOG) performance status of≤3;

9. Systematic usage of immunosuppressive drug or corticosteroid must have been stopped for more than 4 weeks;

10. All other treatment induced adverse events must have been resolved to

7. Subjects need systematic usage of immunosuppressive drug;
8. Planed operation, history of other related disease, or any other related laboratory tests restrict patients for the study;
9. Other reasons the investigator consider the patient may not be suitable for the study.
