NCT03473496•Zhujiang Hospital

View on ClinicalTrials.gov

Summary

Multiple myeloma（MM） is one of the most common malignant diseases in the blood system.There is still no cure for the disease which only control the development of the disease in various ways.Chimeric Antigen Receptor-transduced T cell (CAR-T) therapy is one of revolutionary targeted immunotherapy.The efficacy of CAR-T cells for the treatment of acute B lymphocytic leukemia has been widely recognized, and several clinical trials have been reported in the treatment of multiple myeloma with CAR-T cells.

Detailed Description

Multiple myeloma（MM） is one of the most common malignant diseases in the blood system.There is still no cure for the disease which only control the development of the disease in various ways. In recent years, the understanding of pathogenic molecular mechanism in MM , many new types of drugs can be used in the treatment of this disease, one of the most widely used is proteasome inhibitors and immune regulator.Hematopoietic stem cell transplantation has also been shown to improve complete remission rates and prolong patient survival.Combined with the advantages of multiple therapies, chimeric antigen receptor T cells (CAR-T) have gradually become one of the strongest and most powerful weapons against multiple myeloma. CAR - T cells was taken in the form of genetic modification, and specific identified target antigen monoclonal antibody of single variable region (scFv) expression in T cell surface, and coupled with the activation of intracellular proliferation signal domain. When scFv recognizes antigens expressed in malignant cells, it stimulates the activation signal of downstream T cells and produces specific killing effects. CAR-T therapy is one of revolutionary targeted immunotherapy.The efficacy of CAR-T cells for the treatment of acute B lymphocytic leukemia has been widely recognized, and several clinical trials have been reported in the treatment of multiple myeloma with CAR-T cells.Throughout registration of clinical trials and published research results, B-cell maturation antigen (BCMA) as one of targets , its effect is more significant than other molecules.As with BCMA antigens, cluster of differentiation 138(CD138), cluster of differentiation 56 (CD56) or cluster of differentiation 38(CD38) antigens are also highly expressed in multiple myeloma cells.With CD138 as the target for the treatment of CAR-T cells, several clinical studies have been registered, and the results show that some of them are effective. In order to lay a foundation for the application of relapsed/refractory multiple myeloma patients with CAR-T therapy，objects are refractory/ relapsed patients with multiple myeloma,and plans to into the group of the number of cases in 50 cases.The main content is safety, efficacy and feasibility analysis of the CAR-T cells （single CAR-T or double CAR-T cells with BCMA、CD138、CD56 or CD38 ) in the treatment of refractory/relapsed multiple myeloma.

•6. The function of important organ was satisfied:(1)cardiac ultrasound indicated that cardiac ejection fractions is more than 50%（EF≥50%）, and the electrocardiogram showed no obvious abnormality;(2)Blood oxygen saturation is more than 90%（SpO2≥90%）;(3)Creatinine（Cr） is less than 2.5 times normal range;(4)Alanine transaminase（ALT） and glutamic-oxalacetic transaminase（AST）is less than 3 times normal range,and total bilirubin is less than 2 milligram per deciliter(TBil≤2.0mg/dL).
•7. After discussion by the expert group, the patient's condition was analyzed and combined with the general physical condition of the patient, the benefit of participating in the clinical trial was greater than the risk.
•8. Volunteered for this clinical trail and signed a consent form .

Exclusion Criteria

•1. Patients with high tumor burden or progression of disease need to control the progression of disease in order to decrease the tumor burden.
