Outcome Measures
Primary Outcomes (3)
Dose limited toxicity (DLT)
DLT is defined as any of the predefined adverse events (AEs) related to KSVCBD occurring within 28 days after KSVCBD infusion (CRS and ICANS will be graded according to the ASTCT 2019 criteria, and other AEs will be evaluated using CTCAE v6.0).
Within 28 days post-infusion
Adverse events (AEs) and serious adverse events (SAEs)
Incidence and severity of AEs and SAEs
Within 24 months post-infusion
Adverse events of special interest (AESI)
AESI including grade ≥3 Cytokine Release Syndrome (CRS), Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS), and infections

EXPERIMENTALInterventions
KSVCBD injection is a CD19/BCMA-targeted in vivo-edited CAR-T cell injection. Three dose levels are predefined, and KSVCBD will be dose-escalated per the protocol-specified doses.
