简要总结
This is a single-arm, open-label, single-center clinical trial to evaluate the safety, tolerability, efficacy, pharmacokinetics, and pharmacodynamics of QI-019B in patients with relapsed/refractory multiple myeloma.
详细描述
This investigator-initiated clinical study aims to evaluate QI-019B, the lentiviral vector that carries a BCMA/CD19-targeted CAR, in patients with relapsed or refractory multiple myeloma (MM). The study employs a dose-escalation design to assess safety, tolerability, and preliminary efficacy.

QI-019B Injection
Experimental
QI-019B Injection is an in vivo administered CAR-T gene therapy product that uses a lentiviral vector as the delivery system. Its mechanism of action involves transducing and integrating into the target T cell genome in the patient through the lentiviral vector, achieving stable expression of the CAR transgene, thereby generating CAR-T cells within the body.
干预措施: QI-019B Injection (Drug)
结局指标
主要结局
The number and severity of dose-limiting toxicity (DLT)events
时间窗: Within 28 Days After QI-019B infusion
Dose-limiting toxicity (DLT) refers to a grade ≥3 toxic reaction that occurs within the DLT observation period and is considered by the investigator or collaborators to have a reasonable association with QI-019B treatment(toxicity grading is based on CTCAE 5.0 standards, while grading for cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) follows the 2019 ASTCT consensus criteria)
The total number, incidence, and severity of Adverse Events(AEs)
时间窗: Within 28 Days After QI-019B infusion
The total number, incidence, and severity of Adverse Events(AEs). All other AEs would be assessed according to the Common Terminology Criteria for Adverse Events (CTCAE, Version 5.0)
