This Phase 1 study evaluates a fourth-generation CAR-T cell therapy in multiple myeloma, B-cell lymphoma and other hematologic malignancies. The single-center, open-label, dose-escalation/expansion design assesses safety and effectiveness and seeks to determine the recommended dose of the CAR T-cells. Eligible participants are men and women aged 18 to 75 years with an expected survival of at least 3 months who provide informed consent.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
Inclusion Criteria:
Subjects must meet all of the following criteria to be enrolled:
1\. Voluntarily participate in this clinical study and sign the informed consent form; 2. 18 to 75 years old (including cut-off value), Male and female;; 3. Expected survival of at least 3 months; 4.1 CD19-positive B lymphocyte-derived hematologic malignancies; 4.2 Multiple myeloma patients; 4.3 Non-B cell-derived hematologic malignancies patients with CD7 or other target molecules; 5. The clinical trial values during the screening period meet the following criteria:
1. 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);
2. 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;
3. 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.
Exclusion Criteria:
Any one of the following conditions cannot be selected as a subject:
1. Having received CAR-T therapy targeting the same molecule;
2. Having received other immunotargeted therapy targeting the same molecules;
3. Pregnant or lactating women;
4. Subjects who have previously suffered from other malignancies, with the following exceptions:
1. Having received curative therapy, and no known active disease in the ≥ 3 years prior to the enrollment;
