Chimeric Antigen Receptor Modified T Cells Targeting BCMA for the Treatment of Relapsed/Refractory Multiple Myeloma

Summary

To evaluate the safety and tolerability of chimeric antigen receptor gene-modified T cells targeting BCMA for the treatment of relapsed/refractory multiple myeloma

Eligibility

Inclusion Criteria:

1. Age 18-80 years, no gender restrictions;
2. Diagnosed with refractory/relapsed multiple myeloma through physical examination, pathological examination, laboratory tests, and imaging studies;

7. Peripheral blood lymphocyte absolute count ALC ≥0.5 ×10\^9/L, PLT \>30×10\^9/L, Hb \>80 g/L and has a single collection venous access, and there are no other contraindications for hematopoietic cell separation;
8. Those with fertility must agree to use highly effective contraceptive methods;
9. The subject or their legal guardian can understand and is willing to sign a written informed consent form voluntarily.

Exclusion Criteria:

1. Pregnant or nursing women, as well as women planning to become pregnant within the next six months;

3. History of other tumors (except for those with skin or cervical in situ cancers that have been cured by radical treatment and show no evidence of disease activity);
4. Previously received treatment targeting BCMA;
5. Underwent autologous hematopoietic stem cell transplantation within the last 6 weeks;
6. Presence of uncontrolled active bacterial or fungal infection;
7. Allergic to research-related drugs or cell components;
8. Presence of active autoimmune diseases;
9. Currently have unstable or active ulcers or gastrointestinal bleeding;
10. Unable to cooperate with treatment and efficacy evaluation due to mental or psychological disorders;
11. Received other experimental drug treatments within the last 3 months;
12. The researcher believes that for other reasons, the individual is not suitable for the clinical trial.
