Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: 3 dose groups
Using a dose escalation and rapid titration design, the CAR-T dose groups were (1) 0.5×10^6 CAR-T cells/kg; (2) 1×10^6 CAR-T cells/kg; (3) 3×10^6 CAR-T cells/kg.
Biological: Sup19 CAR-T
The use of Sup19 CAR-T cells to treat hematologic malignancies with prior CD19-targeted therapy failure or CD19 weak expression aims to improve the relapse-free survival rate in patients with hematologic malignancies, providing a novel curative strategy for these patients.
