This is a single center, open-label, dose-escalation/expansion clinical study to evaluate the safety and effectiveness of Fourth-Generation CAR-T, and determine the recommended dose of the CAR T-cells for patients with Multiple Myeloma，B-cell lymphoma and other hematologic malignancies.
White blood cell count ≥ 3.0 × 10e9/L; Absolute neutrophil ≥ 1.0 × 10e9/L; Lymphocyte count ≥ 0.5 × 10e9/L. (The growth factor support is allowed, but growth factor must not have been received within 7 days prior to laboratory testing);
Platelet count ≥ 50 × 10e9/L (No blood transfusion support within 7 days prior to laboratory tests.); Note: Patients with leukemia, multiple myeloma, and lymphoma are not subject to the above blood picture requirements;
Biochemical indicators Serum total bilirubin (TBIL) ≤ 2.5 ULN, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 ULN, or 5 ULN if liver dysfunction is primarily due to tumor invasion); 6. Cardiac function: Subjects must have good hemodynamic stability, left ventricular ejection fraction (LVEF) ≥ 55%; 7. Lung condition: Subjects are not serious infections such as severe pneumonia; 8. ECOG activity status score: 0-2 points; 9. Female subjects must use effective contraception (such as oral prescription contraceptives, injectable contraceptives, intrauterine devices, double blockade, contraceptive patches, male partner sterilization) throughout the study period; Must have a negative serum or urine pregnancy test result at screening and throughout the study.
Having received CAR-T therapy targeting the same molecule;
Having received other immunotargeted therapy targeting the same molecules;
Pregnant or lactating women;
Having received curative therapy, and no known active disease in the ≥ 3 years prior to the enrollment;
