Study design:

Cohort study 

研究目的:

通过动态监测 ASCT 序贯 BCMA CAR-T 治疗 MM 患者过程中,CAR-T 细胞的体内动力学、功能表型以及全身免疫微环境的全景变化,系统揭示 ASCT 重塑的体内环境对 CAR-T 疗效的支持作用,阐明两者协同作用的细胞与分子机制。  

Objectives of Study:

Through dynamic monitoring of the sequential BCMA CAR-T therapy after ASCT in MM patients, the in vivo kinetics and functional phenotypes of CAR-T cells, as well as the panoramic changes of the systemic immune microenvironment, are systematically revealed, elucidating the supportive role of the ASCT-remodeled in vivo environment on CAR-T efficacy and clarifying the cellular and molecular mechanisms of their synergistic effects.

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data will be collected using standardized Case Report Forms (CRFs) and managed through an Electronic Data Capture (EDC) system. Clinical baseline characteristics, treatment information, laboratory results, MRD assessments, CAR-T cell kinetics, immune microenvironment profiling data, and follow-up outcomes will be prospectively recorded. All data will be entered and verified by trained study personnel to ensure accuracy and completeness. De-identified coded data will be used to protect participant confidentiality, and access will be restricted to authorized study investigators. All study data will be securely stored in the Hematologic Molecular Diagnosis Laboratory database of Shanxi Bethune Hospital for long-term preservation.
